Carol is a 56 year old real estate agent who noticed a feeling of nervousness, warmth and rapid heart rate which worsened over a few days. Carol called a friend who drove her to the Emergency Room where the doctors gave her medications to slow the rapid rate (propranolol, a beta blocker). Lab testing confirmed she had Graves’ hyperthyroidism. Carol was sent home with an appointment to see an endocrinologist a week later.
The endocrinologist saw Carol and ran a thyroid lab panel showing a TSH of .001, which is very low. In addition, the other lab tests showed a FreeT3 of 1200 and a FreeT4 of 4.4, both markedly elevated. Her Thyroid Stimulating Immune-globulin (TSI) test was also very elevated, indicating Graves’ Hyperthyroidism. This is an autoimmune disease in which antibodies attack and stimulate the TSH receptor of the thyroid gland causing high thyroid function. Carol was started on a thyroid blocking drug, methimazole 30 mg daily.
Carol Goes to a Health Resort
Unhappy with conventional treatment, Carol traveled to health resort ranch in Arizona specializing in organic raw vegetarian meals and fresh vegetable juices. She went to daily yoga classes, meditation and sauna treatments. The doctor at the Health Resort started Carol on a vitamin supplement program for her thyroid condition which included a potassium iodide capsule containing 65 mg of iodide.
Carol Starts to Feel Better !!
At the Health Ranch, Carol started feeling much better, almost normal, and her repeat her lab panel showed the TSH had gone back up to the normal range of 3.2. The other thyroid labs, the FreeT3 and FreeT4 had also normalized. However, the TSI remained quite elevated with little change.
Carol returned home and visited the endocrinology office. Her endocrinologist reviewed the labs, and then stopped the methimazole blocking drug. He said it was no longer needed. However, the Graves’ antibodies, (the TSI thyroid stimulating antibodies), were still very elevated, so the endocrinologist recommended a subtotal hyperthyroidectomy, a surgical procedure to remove the thyroid gland. Carol was unhappy with this recommendation. She was not keen on having thyroid surgery, and came to see me in the office to get a second opinion.
Coming for a Second Opinion
This case illustrates the beneficial effect of Iodine on Graves’ Disease, showing complete remission with a 65 mg potassium iodine tablet given at a health resort as part of a vitamin program.(1)

The History of Iodine Use for Hyperthyroidism- Exopthalmos Goiter
1811- Discovery of Iodine by Courtois
In 1811, Bernard Courtois, a French chemist accidentally discovered a purple substance which he named, Iodine.(1)
1863 – Dr. Trousseau Accidently Discovers Iodine Cures Graves Disease.
In 1863, Trousseau was called to visit a sick woman with tachycardia caused by Graves’ Hyperthyroidism.(2) Dr. Trouseau intended to write a prescription for tincture of Digitalis to slow the heart rate, but instead wrote for tincture of Iodine by mistake,
Upon initial examination the woman’s heart rate was 140 to 150 times per minute. When Trousseau returned the next day, the lady’s heart rate had slowed to normal. It was then he realized his mistake and discovered the patient actually took 75-100 mg of Iodine over night. He cancelled the Iodine and again prescribed tincture of Digitalis.
The next day, Trousseau again examined the patient and found the pulse had again gone up to 150 beats per minute. Trousseau realized the Iodine induced a beneficial slowing of the heart rate, and remission of hyperthyroid symptoms. Trousseau then returned to the use of iodine, placing the patient back on her original iodine prescription. (2)
Iodine – How does it work in Graves ?
It has been more than 150 years since Trousseau’s accidental discovery of the beneficial effect on Graves’ Disease patients. The question you might ask is: How does it work? What is the effect of Iodine on thyroid cell physiology? A basic science study by Corvilain in 1988 explains that Iodide inhibits hydrogen peroxide generation in the thyroid follicle, an important step in the organification of iodine to the thyroglobulin molecule.(3) Thus by inhibiting organic binding, Iodine inhibits formation and release of thyroid hormone by the thyroid gland, and thyroid levels decline promptly. This explains remission in Graves Hyperthyroidism.(19-21)
In 1920’s, Drs Plummer, Starr, Lahey and Thompson published reports of successful use of Iodine for Graves Hyperthyroidism. (4-6). In the 1930’s and 1940’s, Drs. Thompson, Walcott and Redisch reported on their successful use of Iodine to treat Graves’ Hyperthyroidism. (6-9)
Dr. Redisch in 1940 reported on his case experience which was favorable. One important distinction was made however, between Graves hyperthyroidism and the toxic nodular goiter. Dr Redisch felt that : “Iodine should never be given to patients with old nodular goiters become toxic.”(9)
The Wisdom of Drs Wolf and Wartofsky
In 1948, the great thyroidologists Wolff and Chaikoff published a report which stated (10):
“we do believe that our findings justify the conclusion that an interference in organic binding of iodine by the gland is an integral part of the mechanism by which iodine brings about a remission in Graves’ disease.” (10)
In 1970, the great thyroidologist, Dr. Wartofsky, published his report on the “Inhibition by iodine of the release of thyroxine from the thyroid glands of patients with thyrotoxicosis.” in the Journal of Clinical Investigation (8). He stated,
“the decreased serum T4 concentration could only have resulted from decreased secretion of the hormone by the gland”,
thus explaining how iodine induces remission in Graves Hyperthyroidism.(11)

Iodine Not For Toxic Nodular Goiter
Iodine is contra-indicated in thyrotoxosis caused by toxic nodular goiter. These patients may have a solitary or multiple thyroid nodules, one of which is hyper-functioning. These patients are “toxic”, meaning they are hyperthyroid, because one of these nodules has mutated into a hyper-functioning autonomous nodule.(17-18) In this type of nodule, there has been a mutation in the cell line coding for the TSH receptor causing it to malfunction.. Thus the cells in the autonomous nodule uncontrollably convert iodine into thyroid hormone resulting in hyperthroidism.(17-18)
The Autonomous Thyroid Nodule
My previous article discussed diagnosis and treatment of thyrotoxicosis caused by the autonomous thyroid nodule. The clinical history usually includes some form of Iodine exposure, perhaps obtained from the health food store. Ultrasound thyroid Imaging usually shows a dominant thyroid nodule. Radionuclide imaging wth I-123 or Technetium 99M usually shows the “Hot Nodule” causing the thyrotoxicosis. The toxic nodule may be solitary, or may be present against a background of multiple nodules.
Since Iodine is useful for Graves’ Disease, and is contra-indicated in the autonomous nodule (toxic nodule), it is important to determine whether the thyrotoxicosis is caused by Graves’ Disease or a toxic nodule (Toxic Multinodular Goiter)
Image at upper left shows radioisotope scan with typical appearance of multiple thyroid nodules in Multinodular Goiter courtesy of IJEM.Arrows point to nodules.
Graves’ Disease is an autoimmune thyroid disease in which there are antibodies to the TSH receptor detectable on blood testing. The newer TRAb Thyroid Receptor Antibodies are specific for Graves Disease. They come in two varieties, the stimulatory antibodies called TSI, and the inhibitory antibodies called TBII, (Thyroid binding inhibitory immunoglobulins). Both are sensitive and specific for Graves’ Disease. The newest TBII test is called the H-TBII which uses human material rather than porcine material for the test. (34, 34a)
Dr Wallaschofski from Germany says in a 2004 article, the h-TBII test should be performed on all patients to differentiate Graves’ from Toxic Multinodular Goiter, (34):
“… the h-TBII should be performed in all patients with hyperthyroidism to differentiate Graves’ disease from non-autoimmune hyperthyroidism such as toxic multinodular goitre” quote from (34)
Above image shows radionuclide thyroid scan. Left Image: normal thyroid uptake. Right Image: Diffusely enlarged thyroid gland with increased radiotracer uptake typical appearance of Graves’ Hyperthyroidism.
The thyroid gland in Graves’ disease is usually smoothly enlarged on imaging and palpation (see image above).
On the other hand, In the patient with toxic Multi-Nodular Goiter, the thyroid gland is usually irregular and bumpy with either solitary nodule or multiple nodules on imaging.(see the above images).
Modern Treatment of Hyperthyroidism
By 1980, treatment of Graves’ Disease had evolved. New anti-thyroid drugs were developed such as PTU and Methimazole (Tapazole). Thyroid ablation with Radioactive I-131 given as an oral capsule was finding popularity. Of course, surgical thyroidectomy remained a treatment options. (29-33)
However, the original Iodine treatment remains in the hospital formulary for preparation of the Hyperthyroid Patient prior to thyroidectomy.(12-13)
In 2009, Dr Sinem Kiyici reported on the use of Lugol’s Iodine in combination with anti-thyroid drugs for preparation of the hyperthyoid patient for thyroidectomy.(14)
First Line Therapy With Iodine
In 2000, Dr. Jamieson reported on the successful treatment of Graves’ disease in pregnancy with Lugol’s iodine. (15) In 2013, Dr. Gangadharan reported on the use of Iodine as first line therapy in a child with Graves’ Disease.(16)
Lithium and Iodine Combination Treatment (49-56)
Lithium carbonate (300 mg tabs) can be an effective treatment for hyperthyroidism. Dosage is usually 300 mg three times a day. Blood levels are checked to avoid toxicity. (49-56) Lithium inhibits the release of thyroid hormone by the thyroid gland. The mechanism is thought similar to that of Iodine.
Perhaps a more effective treatment for Graves hyperthyroidism is found with the combination of both Lithium Carbonate and Iodine (Lugol’s) used together.(49)
Quoted from the Jonathan Wright MD Newsletter (49):
“In 1972, Dr. R Temple at the Mayo CLinic published the first clinical investigation of lithium treatment for Graves’ disease. Using high-dose lithium for 10 individuals, they reported that thyroid hormone levels fell by 20-30 percent within five days.
Twenty-six years later, in a review of more than 10 successful trials of lithium therapy for Graves’ disease, the authors wrote: “a small number of studies have documented [lithium’s] use in the treatment of patients with Graves’ disease… it’s efficacy and utility as an alternative anti-thyroid [treatment] are not widely recognized…”(55)
They also note lithium’s rapid effect: “Lithium normalizes [thyroid hormone] levels in one to two weeks…” Of course, they also caution that “toxicity precludes its use as a first-line or long-term therapeutic agent.”
But if they’d just added flaxseed oil and vitamin E to their treatment, they would have basically eliminated the risk of toxicity. in fact, every individual (except one) whom I’ve treated with iodine-iodide (in the form of Lugol’s Solution) and high dose lithium has had blood tests for thyroid hormone return to normal within two weeks. Their tests then stay normal as long as they use the Lugol’s solution and high dose lithium.” (49-56)
Once such protocol used Lithium Carbonate 300 mg three times a day for three days, then start the Lugol’s Iodine 5 % solution – 3 drops three times a day. (48-56)
Lithium Induced Hand Tremor
A common adverse effect of Lithium is hand tremor, which may be alleviated with addition of Vitamin B6 (P-5-P). (60) Lithium toxicity may be avoided with the use of Flax Seed Oil Essential Fatty Acids, and Vitamin E.
Drs Guy Abraham, David Brownstein and George Flechas of the Iodine Project recommend Iodine for treatment of Graves’ Hyperthyroidism. However, They advocate a nutritional supplement program prior to using Iodine: Selenium. Magnesium, Unrefined sea salt and vitamin C. (22-23)
Graves’ is an Autoimmune Disease
Graves’ disease is an autoimmune disease in which auto-antibodies attack and stimulate the TSH receptor. As such, based on the work of Allesio_Fasano, gluten sensitivity and leaky gut has been implicated in the etiology.(48) See my previous article on this.
Underlying gluten sensitivity is the common cause of leaky gut and auto-immune disease. The mechanism of molecular mimicry has been proposed with leakage of bacteria into the blood stream which invokes an immune response. The bacteria, Yersina has been implicated in Graves’ Disease. Antibodies to Yersinia cross react with the TSH receptor, producing hyperthyroidism by stimulating the TSH receptors in the thyroid gland.(36-42). Similarly, thyroid eye disease (TED) is the result of autoimmune attack on TSH receptors or other antigens in the extra-ocular muscles, peri-orbital adipose and connective tissue.(43-47)
Radio-Active Iodine Worsens Thyroid Eye Disease
Over the years, radioactive iodine (I-131) has enjoyed considerable popularity as a treatment for hyperthyroidsm. However, Dr. Jerome M. Hershman laments in 2013 Clinical Thyroidology that radio-Iodine worsens Thyroid Eye Disease (TED).(30)
Dr. Hershmann continues with the following quote: “It is difficult to predict how patients with Graves’ disease will be treated 20 years from now, but I hope that we will have some rational therapy that is directed at the autoimmune origin and that makes our entire current armamentarium obsolete.” (30)
Obviously, there is something yet to be desired with modern treatment of Graves’ Disease. Perhaps treatment with combined Iodine and Lithium is the answer (see below references (49-56).
Addressing the Underlying Auto-Immune Cause
Modern treatment ignores the underlying autoimmune causation, and is concerned solely with controlling the hyperthyroid metabolic state with drugs (methimazole)(31), radioactive iodine and thyroidectomy.(57)
Our program addresses the underlying autoimmune cause.
1) Gluten sensitivity testing with anti-gliadin antibody, and Genetic testing. If positive, a Gluten Free Diet may be curative,
2) Extended Food Reactivity testing, and dietary modification to eliminate reactive foods.
3) Healing the Gut with various nutritional programs including Glutamine, digestive enzymes, probiotics, etc.
4) Selenium level testing and optimization. See my previous article on this.
5) Vitamin D3 level testing and optimization.
6) Low Dose Naltrexone, an immune modulator, has been found useful in autoimmune disease patients.
7) Control and manage hyperthyroid state by inhibiting thyroid function with Iodine, lithium and methimazole (57). In some cases Beta Blocker (atenolol, propranolol) may be required to manage tachycardia.
8) Block and Replace: Once thyroid function has been decreased sufficiently with medical treatment (Methimazole, Lithium and/or Iodine), Thyroid Hormone replacement can be started with the goal of suppressing TSH. We prefer to use natural thyroid medication (NDT) such as Naturethroid from RLC labs, rather than T4 only levothyroxine commonly used by endocrinologists and primary carer physicians. By suppressing TSH, we have seen antibodies levels decline in autoimmune thyroid cases.
7) Thyroid Eye Disease (TED) in the Graves’ patient should be managed by coordinated team of physicians, endocrinologists, and ophthalmologists with specialty experience in managing TED. This typically involves a neuro-ophthalmologist, an orbital surgeon, and a strabismus surgeon. Unfortunately the usual treatments with antithyroid drugs and thyroidectomy do not improve thyroid eye disease. In fact, radioiodine therapy for Graves’ disease can worsen thyroid eye disease. (43)

“If this proposed mechanism is valid, orthoiodosupplementation,30 combined with magnesium intake between 800-1,200 mg/day, a daily amount this author recommended 21 years ago 98 for magnesium sufficiency, should reverse autoimmune thyroiditis. This nutritional approach is also effective in Graves’ autoimmune thyroiditis as previously discussed.”
Lectures on clinical medicine: delivered at the Hôtel-Dieu, Paris, Volume 1 By Armand Trousseau page 586-7
In 1863, Trousseau inadvertently used tincture of iodine successfully in a patient with exophthalmic goiter.55 “In the course of October, 1863, I was consulted by a young married lady, who habitually resides in Paris. She was suffering from subacute exophthalmic goiter… I still found her heart beat at the rate of 140 to 150 times in the minute… I wished to administer at the same time tincture of digitalis, but preoccupied with the idea that there would be some danger in giving iodin, I wrote iodin instead of digitalis, so that the patient took from 15 to 20 drops of tincture of iodin a day for a fortnight. (For the reader’s information, “tincture of iodin” is a 10% solution of iodine in 95% ethanol. The daily amount ingested was 75-100 mg). When she than came back to me her pulse was only 90. I found out my mistake, and I substituted tincture of digitalis for that of iodin, but, after another fortnight, the pulse had again gone up to 150, so that I at once returned to the iodin.” Trousseau had the distinction of performing the first double-blind study of iodine in a cohort of one patient with Graves’ disease. He also achieved remission of Graves’ disease with prolonged administration of potassium iodide.56
Thompson, el al,57 in a 1930 publication, quoted several authors in the late 1800s and early 1900s who used Lugol solution alone successfully in Graves’ disease, with complete remission of the disease, eliminating the need for surgery. Destruction of the thyroid gland with goitrogens and radioiodide was fortunately not then available for the management of Graves’ diseased. Professor Kocher came on the scene in the early 1900s and had an adverse iodophobic effect on the treatment of Graves’ disease. Professor Theodore Kocher carried a lot of weight, being the recipient of the Nobel Prize in Medicine and Physiology in 1909, for his work on “thyroid surgery,” the only Nobel Prize assigned to research on the thyroid gland. He was against the use of iodine/iodide in exophthalmic goiter and all forms of hyperthyroidism.58,59

The value of a short intensive course of iodine medication as a method of preparing a patient with exophthalmic goiter for thyroidectomy has been unquestioned since the report of Plummer1 in 1923. Following his announcement, the use of iodine in this disease rapidly became widespread. It was soon noted by various observers, beginning with Starr, Segall and Means,2 that in cases in which this medication was prolonged, its effect, though striking, was usually only temporary; and that after a few weeks the patient might be as ill as before it was started, if not worse. Thus, in general, the prolonged treatment for exophthalmic goiter with iodine alone has come to be regarded as a futile, if not a dangerous, procedure.
There are, however, some observations in the literature concerning favorable results in exophthalmic goiter with this method of treatment. Trousseau,3 in 1863, mentioned a patient in whom the disease was
Starr, et al 65 from the Massachusetts General Hospital used 15 drops (90 mg) of Lugol gaily for the treatment of exophthalmic goiter, with a 92% success fate, eliminating he need for surgery. “Of these 25 cases, 20 (80%) responded to iodine by a more or less extensive remission of the disease. Of these 20, 12 (48%) responded with the acute iodine resembling the effect produced by subtotal thyroidectomy. In the remaining eight (32%) the remission occurred, but was less extensive. In five unsuccessful cases (20%) two of the patients were pregnant, and one had cardiac decompensation. If these are omitted from the calculation, iodine administration was successful in 20 of 23, or 92% of our hospital cases.”

Wartofsky, et al5 in 1970 evaluated the effect of Lugol solution, administered at five drops (30 mg iodine/iodide) three times a day in five thyrotoxic patients.
Following a well-designed protocol, they reported, “It is concluded that the rapid decrease in T4 secretion induced by iodine is not the result of an acute sustained inhibition of T4 synthesis (the Wolff-Chaikoff effect), but rather results from an abrupt decrease in the fractional rate of thyroid T4 release.”
“Regardless of whether or not its administration was anteceded and accompanied by the administration of large doses of methimazole, iodine induced a rapid decrease in serum T4-127I concentration which could not be explained by an increase in the peripheral turnover of T4, as judged from the metabolism of the 131I-labeled hormone. Hence, the decreased serum T4 concentration could only have resulted from decreased secretion of the hormone by the gland. ”

Combination of potassium iodide and propranolol in preparation of patients with Graves’ disease for thyroid surgery. Feek CM, Sawers JS, Irvine WJ, Beckett GJ, Ratcliffe WA, Toft AD.
Abstract We assessed the efficacy of the combination of propranolol and potassium iodide in the preparation of patients with Graves’ disease for thyroid surgery. Potassium iodide was given orally in a dose of 60 mg three times a day for 10 days before operation in 10 patients who were already receiving propranolol. In contrast to previous experience with either drug used singly, the combined regimen caused a significant fall in mean serum total thyroxine and triiodothyronine to levels in the euthyroid range before operation (P less than 0.001). There was also a significant fall (P less than 0.05) before operation and transient rise after operation in serum reverse triiodothyronine. These preliminary results suggest that the combination of potassium iodide and propranolol may prove to be the optimum preoperative preparation for patients with Graves’ disease.

Lugols preop thyroidectomy

Thyroidectomy is an alternative treatment in the therapy of hyperthyroidism in patients who are non-compliant, drug-resistant or have various side effects to the antithyroid drugs. Preoperative preparation of hyperthyroid patients is extremely important to avoid per operative complications due to severe thyrotoxicosis. We investigated the effects of lugol solution usage with or without thionamides in the rapid preparation of thyroid surgery retrospectively.
Twenty-two patients with Basedow-Graves disease, 19 patients with toxic multinodulary goiter and 3 patients with toxic adenoma were enrolled into the study. Mean ages of patients were 46.6±14.7 years and mean duration of hyperthyroidism was 38.2±59.3 months. The indications of surgical treatment were as follows: unresponsiveness to medical treatment (n=19), pancytopenia (n=9), hepatotoxicity (n=6) allergic reactions (n=3) and noncompliance (n=7) with antithyroid drugs. To restore euthyroidism before surgery, 27 patients treated with lugol solution whereas 17 patients treated with lugol solution and thionamides. Mean dose of lugol solution was daily 27.7±5.5 drops and the mean usage of lugol solution was 9.7±2.3 days. Beta-blocking agents were used in 31 patients. After lugol treatment serum free T4 concentration decreased from 2.5±1.6 to 1.37±0.71 ng/dl (normal range=0.7–1.48 ng/dl) while serum free T3 concentrations decreased from 10.0±7.3 to 3.9±3.7 pg/ml (normal range=1.71–3.71 pg/ml). Percentage changes of serum free T4 and free T3 levels were not different in patients treated with lugol solution alone as compared with patients treated lugol solution and thionamides. All patients were clinically in euthyroid status before surgery. Uneventful total and subtotal thyroidectomy performed in 37 patients while hemithyroidectomy was performed in 7 patients.
In conclusion, lugol treatment with and without antithyroid drugs is safe and effective choice in rapid preparation of patients with hyperthyroidism to thyroidectomy when surgery cannot be delayed.

Here, we present a case of iodine-induced thyrotoxicosis in a patient with multinodular goiter with autonomously functioning tissue. Initially, the source of iodine was not obvious, especially as iodinated contrast agents, amiodarone, or topical antiseptics were not used. Finally, after intensive questioning it was revealed that the consumption of a kelp-containing tea was the sought-after source of excessive iodine.

Iodine-induced hyperthyroidism: occurrence and epidemiology.
Stanbury JB1, Ermans AE, Bourdoux P, Todd C, Oken E, Tonglet R, Vidor G, Braverman LE, Medeiros-Neto G.
We have critically reviewed the available information on iodine-induced hyperthyroidism (IIH) from published sources and other reports as well as the experience of the authors in Tasmania, Zaire, Zimbabwe, and Brazil. Administration of iodine in almost any chemical form may induce an episode of thyrotoxicosis (IIH). This has been observed in epidemic incidence in several countries when iodine has been given as prophylaxis in a variety of vehicles, but the attack rate as recorded has been low. IIH is most commonly encountered in older persons with long standing nodular goiter and in regions of chronic iodine deficiency, but instances in the young have been recorded. It customarily occurs after an incremental rise in mean iodine intake in the course of programs for the prevention of iodine deficiency, or when iodine-containing drugs such as radiocontrast media or amiodarone are administered. The biological basis for IIH appears most often to be mutational events in thyroid cells that lead to autonomy of function. When the mass of cells with such an event becomes sufficient and iodine supply is increased, the subject may become thyrotoxic. These changes may occur in localized foci within the gland or in the process of nodule formation. IIH may also occur with an increase in iodine intake in those whose hyperthyroidism (Graves’ disease) is not expressed because of iodine deficiency. The risks of IIH are principally to the elderly who may have heart disease, and to those who live in regions where there is limited access to medical care. More information is needed on the long-term health impact of IIH or “subclinical” IIH, especially in the course of prophylaxis programs with iodized salt or iodinated oil in regions where access to health care is limited.
Serum Thyroxine and Triiodothyronine Concentrations During Iodide Treatment of Hyperthyroidism, The Journal of Clinical Endocrinology & Metabolism 40.1 (1975): 33-36. CHARLES H. EMERSON, ARLENE J. ANDERSON, WILLIAM J. HOWARD, and ROBERT D. UTIGER
Serum thyroxine (T4) and triiodothyronine (T3) concentrations were measured at frequent intervals in 9 hyperthyroid patients treated with iodide alone. Serum T4 and T3 levels fell initially in all patients. In 6 patients, after a mean fall in serum T4 of 46% and in serum T3 of 47% after 4 to 11 days of therapy, thyroid hormone levels began to rise. In the 3 remaining patients a rise in thyroid hormone levels was not seen following the initial fall. However, in one of this group T4 and T3 levels did not reach the normal range despite 60 days of therapy. These data support the concept that iodide alone is not an ideal agent for the treatment of hyperthyroidism.

In vivo data suggest that high concentrations of iodide lead to reduction in both NIS mRNA and protein levels, partially by a transcriptional mechanism. In vitro results suggest that exposure to high doses of iodide results in a decrease in NIS protein levels that is, at least in part, due to an increase in NIS protein turnover

The effect of iodide on serum thyroid hormone levels in normal persons, in hyperthyroid patients, and in hypothyroid patients on thyroxine replacement.
Philippou G1, Koutras DA, Piperingos G, Souvatzoglou A, Moulopoulos SD.
To clarify the duration and the extent of the antithyroid effect of iodides in hyperthyroidism, and to investigate whether iodides have an additional peripheral effect on the metabolism of thyroid hormones, as has been reported for some organic iodine compounds.
DESIGN:The effect on the peripheral thyroid hormone levels of 150 mg of potassium iodide daily (equivalent to 114 mg of iodide) for 3-7 weeks was compared in 21 hyperthyroid patients and 12 healthy controls. A possible effect of iodide on the peripheral metabolism of thyroid hormones was investigated by assessing the serum levels of thyroid hormone in 12 hypothyroid patients on thyroxine replacement for 2 weeks.
PATIENTS:There were 21 thyrotoxic patients, 12 healthy hospital controls, and 12 patients with complete or near-complete hypothyroidism, on thyroxine replacement.
MEASUREMENTS:The following were measured before and at weekly intervals after iodide administration: (1) pulse rate, (2) serum T4, (3) serum T3, (4) serum TSH, (5) serum thyroxine-binding capacity (TBC), (6) serum rT3, (7) serum thyroxine-binding globulin (TBG), (8) the free-T4 Index, calculated as T4/TBC.
RESULTS:In the hyperthyroid patients serum T4, T3 and rT3 decreased, whereas serum thyroxine-binding globulin and thyroxine binding capacity increased. Serum T3, however, did not become completely normal in all cases. After 21 days, serum T4 and T3 started increasing again in some cases, but other patients remained euthyroid even after 6 weeks. In the normal controls there was a small but significant and consistent decrease in serum T4, T3 and rT3 and an increase in serum TSH. Finally, in the T4-treated hypothyroid patients there was no consistent change, except for an increase of serum T4 at 1 and 14 days and a decrease of serum TSH the first day.
CONCLUSION:Iodides in hyperthyroidism have a variable and unpredictable intensity and duration of antithyroid effect. Their antithyroid effect is smaller in normal controls. They have no important effect on the peripheral metabolism of thyroid hormones.

Q. Can those with Hashimoto’s or Graves’ disease take iodine?
A: I explain this topic in much more detail in my book, but let me summarize the answer. M research has shown that both Hashimoto’s and Graves’ disease are caused, in part, from low iodine. In fact, nearly every new patient with either a diagnosis of Hashimoto’s or Graves’ disease has tested significantly low for iodine. My experience has shown that the vast majority of patients suffering with these illnesses improve their condition when iodine deficiency is rectified. However, some people (including those with and without Hashimoto’s and Graves’ disease) may have problems with iodine supplementation. Of course, there can be an adverse effect to anything, iodine included.
The best results with iodine supplementation occur in those that have their levels checked and are followed by a health care provider who is knowledgeable about iodine. Furthermore, iodine supplementation works better when used as part of a complete holistic treatment regimen.
26) From GOODMAN & GILMAN’S THE PHARMACOLOGICAL BASIS OF THERAPEUTICS – 11th Ed. (2006) :
Mechanism of Action.
High concentrations of iodide appear to influence almost all important aspects of iodine metabolism by the thyroid gland (Roti and Vagenakis, 2005). The capacity of iodide to limit its own transport has been mentioned above. Acute inhibition of the synthesis of iodotyrosines and iodothyronines by iodide also is well known (the Wolff-Chaikoff effect). This transient, 2-day inhibition is observed only above critical concentrations of intracellular rather than extracellular concentrations of iodide. With time, “escape” from this inhibition is associated with an adaptive decrease in iodide transport and a lowered intracellular iodide concentration, most likely due to a decrease in NIS mRNA and protein (Eng et al., 1999). The mechanism of the acute Wolff-Chaikoff effect remains elusive and has been postulated to be due to the generation of organic iodo-compounds within the thyroid (Pisarev and Gartner, 2000).An important clinical effect of high [I-]plasma is inhibition of the release of thyroid hormone. This action is rapid and efficacious in severe thyrotoxicosis. The effect is exerted directly on the thyroid gland and can be demonstrated in the euthyroid subject as well as in the hyperthyroid patient. Studies in a cultured thyroid cell line suggest that some of the inhibitory effects of iodide on thyrocyte proliferation may be mediated by actions of iodide on crucial regulatory points in the cell cycle (Smerdely et al., 1993).In euthyroid individuals, the administration of doses of iodide from 1.5 to 150 mg daily results in small decreases in plasma thyroxine and triiodothyronine concentrations and small compensatory increases in serum TSH values, with all values remaining in the normal range. However, euthyroid patients with a history of a wide variety of underlying thyroid disorders may develop iodine-induced hypothyroidism when exposed to large amounts of iodine present in many commonly prescribed drugs (Table 56-6), and these patients do not escape from the acute Wolff-Chaikoff effect (Roti et al., 1997). Among the disorders that predispose patients to iodine-induced hypothyroidism are treated Graves’ disease, Hashimoto’s thyroiditis, postpartum lymphocytic thyroiditis, subacute painful thyroiditis, and lobectomy for benign nodules. The most commonly prescribed iodine-containing drugs are certain expectorants, topical antiseptics, and radiological contrast agents.
nursing case report of thyroid storm treated with Lugols
RNJournal 2014 Journal of Nursing Deborah L. Bray, RN, BSN, CNS Graduate Student Murray State University
Critical care nurses should be familiar with the regimen of medications administered during thyroid storm. The first medication administered should be an anti-thyroid medication such as propylthiouracil (PTU) which blocks the synthesis of thyroid hormones and inhibits the peripheral conversion of T4 to T3. The dosage is 200-250mg every 4 hours orally or via gastric tube. The nurse should monitor for signs of bleeding and a decreased platelet count. Methimazole, another anti-thyroid medication does not work in the periphery as PTU does; therefore, PTU is the anti-thyroid medication of choice during thyroid storm (Dahlen, 2002; Dulak, 2005; Kaplow & Hardin, 2007).
One to two hours later, a potassium iodide solution such as Lugol’s solution should be administered to prevent the release of stored thyroid hormone into the system. Timing of this medication is important as early administration of iodide may cause the body to synthesize more T4, worsening the toxic state.
The dosage is 8 drops every 6 hours orally or via gastric tube
(Dahlen, 2002; Dulak, 2005; Kaplow & Hardin, 2007).(Dahlen, 2002; Dulak, 2005; Kaplow & Hardin, 2007).

Rapid Preoperative Preparation for Severe Hyperthyroid Graves’ Disease

Conventional preoperative preparation for TX includes antithyroid drugs and iodine administration before surgery and often takes months to render patients euthyroid. Far more rapid control of thyrotoxicosis can be achieved by
the oral administration of iodinated radiographic contrast agents (IRCAs) such as iopanoic acid (IOP) or ipodate, often given in combination with corticosteroids and antithyroid drugs, and -blockers.
IRCAs have a multitude of effects on thyroid physiology and thyroid hormone metabolism. They competitively inhibit types 1 and 2 5 -monodeiodinase in the
liver, brain, and thyroid, thereby blocking the conversion of T4 to T3. This leads to a rapid and persistent reduction of T3, while reverse T3 levels increase due to decreased clearance of reverse T3 (5– 8). IRCAs also decrease serum T4 levels inhyperthyroid patients due to a decrease in the thyroidal organification of iodine and thyroid hormone secretion from the gland due to the iodine released from these agents (9 –11).
However, serum T4 levels decrease more slowly with IRCAs than with potassium iodide treatment, probably reflecting the decrease in the plasma clearance rate of T4 and a decrease in the hepatic uptake of T4 by displacement of T4 from hepatic binding sites (12). Iodine released from IRCAs also reduces intraoperative blood loss by decreasing thyroid vascularity

The near-uniform avoidance of using RAI in patients with Graves’ ophthalmopathy is striking and attributable mainly to the Italian studies showing that RAI worsens ophthalmopathy and that this can be prevented by corticosteroids (4,5). It is difficult to predict how patients with Graves’ disease will be treated 20 years from now, but I hope that we will have some rational therapy that is directed at the autoimmune origin and that makes our entire current armamentarium obsolete.

Initial treatment of thyrotoxic Graves’ disease with methimazole: a randomized trial comparing different dosages.
Messina M, Milani P, Gentile L, Monaco A, Brossa C, Porta M, Camanni F.
We evaluated the efficacy of different doses of methimazole (MMI) as the initial therapy for Graves’ disease. Fourteen patients were treated with 15 mg/die of the drug (group A) and 14 with 30 mg/die (group B). Blood samples for T3, T4, FT3 and FT4 were obtained before beginning therapy, every 48 h during the first 12 days and on the 45th day of treatment. All these hormonal parameters fell significantly from the 2nd day of therapy in both groups. All the patients, except for one in group B, had normal or subnormal levels of thyroidal hormones on the 45th day of treatment. The comparison between the two groups of regression coefficients over the first 12 days showed no significant differences. The absolute decrease of each examined parameter on day 12 was positively correlated with the relevant pretreatment value. These results demonstrate that doses of MMI (15 mg/die) much lower than those commonly recommended are able to rapidly control thyroidal overproduction as effectively as 30 mg/die.

Benefit of short-term iodide supplementation to antithyroid drug treatment of thyrotoxicosis due to Graves’ disease.
Takata K1, Amino N, Kubota S, Sasaki I, Nishihara E, Kudo T, Ito M, Fukata S, Miyauchi A.Combined treatment with anti-thyroid drugs (ATDs) and potassium iodide (KI) has been used only for severe thyrotoxicosis or as a pretreatment before urgent thyroidectomy in patients with Graves’ disease. We compared methimazole (MMI) treatment with MMI + KI treatment in terms of rapid normalization of thyroid hormones during the early phase and examined the later induction of disease remission.
DESIGN AND PATIENTS: A total of 134 untreated patients with Graves’ disease were randomly assigned to one of four regimens: Group 1, MMI 30 mg; Group 2, MMI 30 mg + KI; Group 3, MMI 15 mg and Group 4, MMI 15 mg + KI. For easy handling, KI tablets were used instead of saturated solution of KI. KI was discontinued when patients showed normal free thyroxine (FT4) levels but MMI was continued with a tapering dosage until remission. Remission rate was examined during a 4- to 5-year observation.
MEASUREMENTS: Serum FT4, FT3 and TSH were measured by chemiluminescent immunoassays. TSH receptor antibody (TRAb) was assayed with TRAb-ELISA. Goitre size was estimated by ultrasonography.
RESULTS: After 2 weeks of treatment, normal FT4 was observed in 29% of patients in Group 1 and 59% (P < 0.05) of patients in Group 2. Furthermore, normal FT4 after 2 weeks of treatment was observed in 27% of patients in Group 3 and 54% (P < 0.05) of patients in Group 4. Similarly, FT3 normalized more rapidly in Groups 2 and 4 than in Groups 1 and 3. None of the patients showed an increase in thyroid hormones or aggravation of disease during combined treatment with MMI and KI. The remission rates in Groups 1, 2, 3 and 4 were 34%, 44%, 33% and 51%, respectively, and were higher in the groups receiving combined therapy but differences among four groups did not reach significance.
CONCLUSIONS: Combined treatment with MMI and KI improved the short-term control of Graves’ hyperthyroidism and was not associated with worsening hyperthyroidism or induction of thionamide resistance.

Graves’ disease is the most common cause of hyperthyroidism in the developed world. It is caused by an immune defect in genetically susceptible individuals in whom the production of unique antibodies results in thyroid hormone excess and glandular hyperplasia. When unrecognized, Graves’ disease impacts negatively on quality of life and poses serious risks of psychosis, tachyarrhythmia and cardiac failure. Beyond the thyroid, Graves’ disease has diverse soft-tissue effects that reflect its systemic autoimmune nature. Thyroid eye disease is the most common of these manifestations and is important to recognise given its risk to vision and potential to deteriorate in response to radioactive iodine ablation. In this review we discuss the investigation and management of Graves’ disease, the recent controversy regarding the hepatotoxicity of propylthiouracil and the emergence of novel small-molecule thyroid-stimulating hormone (TSH) receptor ligands as potential targets in the treatment of Graves’ disease.

TSH-receptor antibody measurement for differentiation of hyperthyroidism into Graves’ disease and multinodular toxic goitre: a comparison of two competitive binding assays.
Pedersen IB1, Knudsen N, Perrild H, Ovesen L, Laurberg P.
Graves’ disease is characterized by stimulating autoantibodies to the TSH-receptor (TRAb). The aim of this study was to compare the performance of a new TRAb assay based on competitive binding to recombinant human TSH-receptors (H-TRAb) with an assay employing purified porcine TSH-receptors (P-TRAb). Furthermore, to evaluate the applicability of the H-TRAb assay to discriminate between patients with hyperthyroidism due to Graves’ disease (GD) and multinodular toxic goitre (MNTG).
DESIGN AND MEASUREMENTS: H-TRAb and P-TRAb were measured in patients with newly diagnosed hyperthyroidism due to GD (n = 106) and MNTG (n = 94). For comparison, TRAb was measured in patients with primary autoimmune hypothyroidism, euthyroid subjects with an enlarged thyroid gland by ultrasound, and healthy controls (n = 100 for each group). Patients were consecutively included from a population survey.
RESULTS: If the cut-off values recommended by the manufacturer for TSH-receptor antibody positivity were used for evaluation, the sensitivity of the H-TRAb assay vs. the P-TRAb assay in diagnosing GD was: 95.3/67.9% (P < 0.001). Specificity was (H/P-TRAb): 99/99%. The sensitivity of P-TRAb was increased if the upper 97.5% limit of measurements in controls was used as cut-off (H-TRAb vs. P-TRAb: 95.3/80.2%, P < 0.001). Specificity (H/P-TRAb): 98/98%. The difference between assay performance may partly be due to a better technical performance of the H-TRAb assay with more reliable results in the low range of measurements. However, even in GD patients with clearly measurable TRAb, 25% had a P-TRAb < 50% of the value expected from the H-TRAb measurement. This suggests that a subgroup of patients produce TRAb with a higher affinity for the human than the porcine TSH receptor. A relatively high proportion of patients with MNTG were TRAb positive (H-TRAb/P-TRAb: 17/9%). Characteristics of H-TRAb positive and negative MNTG patients were compared. There was no difference between size of thyroid gland and number of nodules by ultrasonography. H-TRAb positive patients had significantly higher serum T4 and T3 and a greater number were TPO-Ab positive.
CONCLUSIONS: H-TRAb diagnosed Graves’ disease with a high sensitivity and specificity than P-TRAb. The high occurrence of TRAb in multinodular toxic goitre might in part reflect an overlap between Graves’ disease and multinodular toxic goitre in some patients.

Effect of sodium ipodate and iodide on free T4 and free T3 concentrations in patients with Graves’ disease. Robuschi G, Manfredi A, Salvi M, Gardini E, Montermini M, d’Amato L, Borciani E, Negrotti L, Gnudi A, Roti E.
Graves’ hyperthyroid patients were treated daily for 10 days with 1 g sodium ipodate, a cholecystographic agent which exerts a blocking effect on the peripheral conversion of T4 to T3, or with 12 drops of saturated solution of potassium iodide (SSKI). Serum concentrations of free T4 (FT4) and free T3 (FT3) were measured before, during and 5 and 10 days after the administration of each drug. Sodium ipodate treatment induced a rapid decrement of serum FT4 concentrations which declined from 48.9 +/- 6.6 pg/ml to 26.0 +/- 2.7 pg/ml. In these patients serum FT3 concentrations declined from 12.4 +/- 2.0 pg/ml to 2.5 +/- 0.4 pg/ml. Ten days after sodium ipodate withdrawal, serum FT4 and FT3 concentrations returned to baseline values. In patients treated with SSKI serum FT4 concentrations declined from 51.1 +/- 8.8 pg/ml to 11.3 +/- 1.4 pg/ml and FT3 from 15.7 +/- 2 pg/ml to 2.6 +/- 0.3 pg/ml. Moreover, after therapy interruption serum free thyroid hormone concentrations returned to baseline values in these patients. Serum FT4 pattern during the study was not different between the two groups of subjects whereas serum FT3 concentrations were significantly lower in patients treated with sodium ipodate. These findings indicate that SSKI and sodium ipodate are effective in inducing a rapid decrement of serum free thyroid hormone concentrations. Therefore the employment of these drugs may be useful in the treatment of patients with thyroid storm and those undergoing thyroidectomy

The objective was to report a case of a woman with celiac disease presenting with hyperthyroidism and iron-deficiency anemia. Methods. We report the clinical course of this patient and her laboratory findings. We highlight the important associations between hyperthyroidism, iron-deficiency anemia, and celiac disease. The literature is reviewed for the typical and atypical presentations of celiac disease in relation to hyperthyroidism
and iron-deficiency anemia. Results. A 37-year-old woman presented with symptoms of hyperthyroidism and was found to have iron-deficiency anemia. During the work up for iron-deficiency anemia, she was diagnosed with celiac disease on small-bowel biopsy. After being placed on a gluten free diet, symptoms of hyperthyroidism improved without anti-thyroid medication.
Conclusion. Our case demonstrates that routine screening for celiac disease should be highly considered for patients with both hyperthyroidism and

Thyrotrophin (TSH) binding sites on Yersinia enterocolitica recognized by immunoglobulins from humans with Graves’ disease. Heyma P, Harrison LC, Robins-Browne R. Abstract
Antibodies against the gram negative enteric bacterium Yersinia enterocolitica have been found in a high proportion of persons with autoimmune thyroid disorders, especially in those with Graves’ disease or hyperthyroidism (Shenkman & Bottone, 1981). There is strong evidence that Graves’ disease is caused by receptor autoantibodies which mimic the bioeffects of thyroid stimulating hormone (TSH) on the thyroid (Manley, Knight & Adams, 1982).
Recently, saturable binding sites for TSH were demonstrated in Y. enterocolitica under non-physiological conditions (Weiss et al., 1983). We have characterized TSH binding sites on Y. enterocolitica under physiological conditions and studied their interaction with Graves’ immunoglobulins (Ig’s). Saturable and specific binding of receptor-purified 125I-TSH to lysozyme/EDTA-treated Y. enterocolitica (serotype 03) was demonstrated under both non-physiological and physiological conditions. Scatchard binding plots were linear indicating a single class of binding site (Kd 1 X 10(-7) M, maximum of 30,000 binding sites per cell). In the presence of Graves’ Ig’s the binding of 125I-TSH to Y. enterocolitica was significantly inhibited. Graves’ Ig’s also precipitated a protein of relative molecular mass (Mr) 64,000 from Triton-solubilized, 125I-labelled Y. enterocolitica, similar in size to one of the proteins precipitated by Graves’ Ig’s from human thyroid membranes.
These findings are consistent with the hypothesis that thyroid autoimmunity may be triggered by bacterial infection via a mechanism involving crossreactivity at the level of the TSH receptor. They also suggest that elements of mammalian endocrine systems are highly conserved and have a function in prokaryotes.

[Antibodies to Yersinia enterocolitica in immunogenic thyroid diseases].
[Article in German] Petru G, Stünzner D, Lind P, Eber O, Möse JR.
In 1976 Shenkman et al. revealed that in patients with thyroid disorders antibodies against Yersinia enterocolitica could be demonstrated in increased frequency. In 1983 Ingbar et al. first established that the gram-negative bacterium Yersinia enterocolitica shows on its surface saturable binding sites for thyrotropin (TSH). If such binding sites resemble immunologically human TSH receptors this would indicate that TSH receptor antibodies could be produced in selected individuals having been infected with bacteria showing TSH receptors. The aim of our study was to compare the incidence of antibodies against Yersinia enterocolitica in two groups of thyroid disorders which are either immunogenic (Graves’ disease and Hashimoto thyroiditis) or non-immunogenic (toxic adenomas, endemic goitre). In our series of 111 patients antibodies against Yersinia enterocolitica were demonstrated in a significantly higher percentage (36.3%) in patients suffering from immunogenic than in patients with non-immunogenic thyroid disorders (19.6%). The antibody titres were mainly directed towards Yersinia subtypes 8 and 3. It may, therefore, be assumed that the gram-negative bacterium Yersinia enterocolitica may have an active part in triggering immunogenic thyroid diseases such as Graves’ disease or Hashimoto thyroiditis.

Abstract The prevalence of increased titres of antibodies to Yersinia enterocolitica (serotype 3) has been studied in sera from patients with various thyroid diseases. In contrast to the low prevalences of the antibodies in healty subject (24.3%), titres (greater than 10) of anti-Yersinia enterocolitica (anti-Yersinia) were found more frequently in patients with thyroidal disorders, especially in Graves’ disease (70.0%).
Furthermore, high titres of the antibodies (greater than or equal to 160) were found only in patients with Graves’ disease.
There was no significant correlation between the titers of anti -Yersinia antibodies and those of anti-TSH receptor antibodies in sera from patients with Graves’ disease. In seven individual samples of sera, the anti- Yersinia antibody titer was high before treatment, but the decrease in the anti-TSH receptor antibody titer following treatment was associated with a simultaneous decline in anti-Yersinia antibodies in all of them. A highly positive and significant correlation between the titers of anti-TSH receptor antibodies and anti-Yersinia antibodies was obtained in each of them. These findings could be merely a reflection of the measurement of the cross-reaction of anti-Yersinia antibodies with anti-TSH receptor antibodies but the possibility of an association between Yersinia infection and the production of anti-TSH receptor antibodies in at least some patients with Graves’ disease cannot be ruled out.

It has previously been proposed that subclinical Yersinia enterocolitica infection may play a role in autoimmune thyroid disease (AITD). In this study, we investigated the relationship between the thyroid autoantibodies and the antibodies that produced against different serotypes of Y. enterocolitica. A total of 215 subjects were included into the study (65 newly diagnosed Graves’ disease [GD], 57 Hashimoto’s thyroiditis [HT], 53 nontoxic diffuse goiter [NTDG], and 40 subjects for control group [CG]). Thyroid receptor antibodies (TRAb), thyroid and agglutinating antibodies against Y. enterocolitica serotype O:3, O:5, O:8, O:9 were measured in the blood samples. The highest incidence of Y. enterocolitica antibody positivity was measured in GD (53.8% for O:3, 29.2% for O:5, 44.6% for O:8, and 40% for O:9) and followed by HT. In patients with GD, TRAb levels were also higher than in patients with HT, NTDG, and CG. There was no difference between NTDG and CG in respect to the titer levels and the positivity of both TRAb and Y. enterocolitica antibodies. There was also a weak linear correlation between TRAb level and the titer of antibodies against Y. enterocolitica antigens. It can be concluded that Y. enterocolitica infection may play a role in etiology of GD in Turkey.

Too early to dismiss Yersinia enterocolitica infection in the aetiology of Graves’ disease: evidence from a twin case-control study. Brix TH, Hansen PS, Hegedüs L, Wenzel BE. Department of Endocrinology and Metabolism, Odense University Hospital, Odense, Denmark.
Yersinia enterocolitica (YE) infection has long been implicated in the pathogenesis of Graves’ disease (GD). The association between YE and GD could, however, also be due to common genetic or environmental factors affecting the development of both YE infection and GD. This potential confounding can be minimized by investigation of twin pairs discordant for GD. We first conducted a classical case-control study of individuals with (61) and without (122) GD, and then a case-control study of twin pairs (36) discordant for GD. Immunoglobulin (Ig)A and IgG antibodies to virulence-associated Yersinia outer membrane proteins (YOPs) were measured. The prevalence of YOP IgA and IgG antibodies.
RESULTS: Subjects with GD had a higher prevalence of YOP IgA (49% vs. 34%, P = 0.054) and YPO IgG (51% vs. 35%, P = 0.043) than the external controls. The frequency of chronic YE infection, reflected by the presence of both IgA and IgG YOP antibodies, was also higher among cases than controls (49%vs. 33%, P = 0.042). Similar results were found in twin pairs discordant for GD. In the case-control analysis, individuals with GD had an increased odds ratio (OR) of YE infection: IgA 1.84 (95% CI 0.99-3.45) and IgG 1.90 (95% CI 1.02-3.55). In the co-twin analysis, the twin with GD also had an increased OR of YE infection: IgA 5.5 (95% CI 1.21-24.81) and IgG 5.0 (95% CI 1.10-22.81).
CONCLUSION: The finding of an association between GD and YE in the case-control study and within twin pairs discordant for GD supports the notion that YE infection plays an aetiological role in the occurrence of GD, or vice versa.

Rarer conditions include orbital neoplasms and carotid artery – cavernous sinus fistulas. New onset diplopia may result from cranial nerve palsies, internuclear ophthalmoplegia, or myasthenia gravis.
Management Patients with Graves’ ophthalmopathy should be managed by a coordinated team of primary care physicians, endocrinologists, and ophthalmologists with specialty experience in managing TED. This typically involves a neuro-ophthalmologist, an orbital surgeon, and a strabismus surgeon. The complicated nature of treatment often requires coordination of medical, surgical and radiation therapy.22 Uncontrolled thyroid function is associated with more severe thyroid eye disease.23,24 However, antithyroid drugs and surgical subtotal/near-total thyroidectomy therapies typically do not improve the ophthalmic disease course.25,26 In fact, radioiodine therapy for Graves’ disease can exacerbate ophthalmic disease;

The thyroid stimulating hormone receptor (TSHR) is over-expressed in orbital fibroblasts and adipose tissue in TED patients
Higher levels of TSHR mRNA expression are found in patients with clinically active disease when compared to patients with inactive TED
Methimazole, carbimazole, and propylthiouracil are the main drug treatments blocking thyroid hormone synthesis. They are frequently used in an attempt to achieve remission or as preparative therapy before radioactive iodine or thyroid surgery. After active concentration by the thyroid, the drugs inhibit thyroid peroxidase mediated iodination of tyrosine residues in thyroglobulin. Propylthiouracil had the additional benefit of inhibiting the peripheral conversion of thyroxine (T4) into triiodothyronine (T3).
Characteristic enlargement of the extraocular muscles and proliferation of adipocytes result in the clinical findings, such as eyelid retraction, exophthalmos, and strabismus of TED.
Conclusion Thyroid eye disease is a common cause of orbital disease in adults. The pathogenesis is an active area of research and many immunologic aspects of the disease have been elucidated. Research of serum markers may assist in the diagnosis, prognosis and response to therapy through their ability to improve the classification of TED patients. Characteristic enlargement of the extraocular muscles and proliferation of adipocytes result in the clinical findings, such as eyelid retraction, exophthalmos, and strabismus of TED. All patients require management of their systemic thyroid disease. Most cases of TED can be managed conservatively. Symptomatic treatment with lubrication often suffices for those with mild TED. Individuals with moderate to severe TED may require an escalation of therapy including steroids, radiation or immunomodulation. Intravenous glucocorticoids have the best response rate and the lowest incidence of side effects and thus play a significant role in the management of moderate to severe as well as sight-threatening TED. Surgical management is required when medical management fails. An emerging understanding of the immunologic pathogenesis will likely evolve the management of TED over the next decade.

autoimmunity against a thyroid-stimulating hormone receptor (TSH-r)–like protein in the orbital preadipocyte and, possibly, extraocular muscle fibre.
autoimmunity against TSH-r, expressed in fat and connective tissue, could explain the development of pretibial myxedema, acropachy and the OCT component of TAO
the eye-muscle and OCT–fat reactions are both autoimmune disorders that can occur alone or together in patients with thyroid autoimmunity, manifesting as 3 subtypes of TAO: ocular myopathy, congestive ophthalmopathy or mixed disease. In ocular myopathy, double vision, reduced eye movement and increased volumes of eye muscle (seen with orbital imaging techniques) result from damage to the eye muscles. In congestive ophthalmopathy, eye swelling, redness, chemosis and increased tearing are caused by inflammation in the periorbital tissues. Mixed disease is the most common manifestation of TAO. Chronic eyelid lag, occurring alone or with other features of TAO, may be a fourth subtype

Reversing hyperthyroidism by Jonathan Wright MD
I have used that treatment for my patients with tremendous success ever since that study was released. In fact, every individual (except one) whom I’ve treated with iodine-iodide (in the form of Lugol’s Solution) and high dose lithium has had blood tests for thyroid hormone return to normal within two weeks. Their tests then stay normal as long as they use the Lugol’s solution and high dose lithium.
I have my patients use five drops of Lugol’s iodine three times a day for two or three days. Then I have them add 300 milligrams of lithium carbonate three times a day in addition to the Lugol’s. Lugol’s Solution is available at any pharmacy, but you’ll have to get a prescription from your physician.
Lithium and iodine combination therapy for thyrotoxicosis. Acta endocrinologica, 94(2), 174-183. Boehm, T. M., Burman, K. D., Barnes, S., & Wartofsky, L. (1980). Walter Reed Army Hospital
In order to compare the relative therapeutic efficacy of iodine (I) and lithium (Li) in thyrotoxicosis, investigate possible additive effects of these agents, and examine their effect upon thyroidal release, 17 thyrotoxic patients were assigned to groups given either I (n = 9) or Li (n = 8) alone during an initial treatment period, with the alternate drug added as combination treatment during a second treatment period. Half of the patients received methimazole (MMI). Three additional thyrotoxic patients received I during both treatment periods to evaluate the possibility of cumulative I effect upon thyroidal release during the second treatment period. A double isotope technique was utilized as an index of thyroidal release, employing 125I as an intra-thyroidal label and [131I] T4 as a marker of T4 disposal. During the first treatment period either I or Li induced comparable, significant (P < 0.05) decreases in thyroidal release, as measured by slopes of ratios of serum PB125I: PB131I and by percentage inhibition of fractional T4 release rate. In response to Li, there was a 55% decrease in the slope of PB125I: PB131I with MMI and a 52% decrease without MMI.
In response to I, there was a 70% decrease in the slope of PB125I: PB131I with MMI and a 57% decrease without MMI.
Further significant (P < 0.05) decreases in the slopes of these ratios during the second, combined treatment period (I + Li) occurred only in those patients who had initially received I. No further decreases in the second treatment period were seen in patients receiving I during both treatment periods. Thus, I and Li together display additive inhibition of thyroidal release only if I is administered initially, but the combination, if Li is used first, does not appear to be more effective than Li alone.

Seven patients judged to be euthyroid following treatment of diffuse toxic goiter were studied to determine if they were susceptible to lithium induced hypothyroidism. Lithium carbonate was administered for 4-7 weeks in a dosage (900 mg/day) which maintained serum lithium levels between 0.5-1.0 mEq/l. Blood was obtained weekly for the determination of serum 3,5,3′-triiodothyronine (T3), thyroxine (T4), 3,3′,5′-TRIIODO-L-thyronine (reverse T3, rT3) and thyrotropin (TSH). Values observed during lithium therapy were compared to those obtained prior to, and approximately one week after discontinuing lithium.
During the pretreatment preiod, mean (+/- SE) serum T3, T4, and rT3 concentrations were
130 +/- 21 ng/100 ml, 7.6 +/- 0.4 mug/100 ml and 48 +/- 8 ng/100 ml, respectively, and decreased during lithium administration with the lowest T3, T4 and reverse T3 concentrations of the lowest T3, T4 and reverse T3 concentrations of
92 +/- 8 ng/100 ml, 4.9 +/- 0.6mug/100 ml, and 33 +/- 6 ng/100, ml, respectively, being reached between the fourth and sixth weeks of study. Thereafter, and in spite of continued treatment with lithium, values for serum concentrations of T3, T4, and rT3 plateaued, or actually increased in 4, 6, and 5 subjects, respectively. Serum TSH concentrations remained 3.0 muU/ml or less throughout the study in 6 patients; 2 of these subjects had no TSH response to thyrotropin-releasing hormone (TRH), even though they had been euthyroid for 3 and 10 months. These data suggest that patients euthyroid following treatment of diffuse toxic goiter display sensitivity to the antithyroid effects of lithium. Furthermore, these observations support the thesis that the inhibitory effects of lithium and iodine upon thyroid hormone synthesis or secretion may involve a similar mechanism of action since increased thyroidal iodine content may be a consequence of therapy with either agent.

[Results of lithium treatment in severe hyperthyroidism].
[Article in German] Wünsch C, Heberling HJ. Abstract
Up to the present time lithium therapy is under discussion in patients with severe, particularly of contrast remedy induced hyperthyroidism. The aim of our presentation was to investigate if the short term combined methimazole-lithium therapy in the initial phase will be advantageous in contrast to the monotherapy of methimazole. The examination in our material showed a good effectiveness and tolerance of the combined therapy. At present the precise mechanism of action of lithium has not been elucidated. There is evidence that lithium inhibits the thyreoglobulin hydrolysis and the peripheral conversion of thyroxin to triiodothyronin. Other actions are under discussion. In our opinion only the combined methimazole-lithium therapy will be advantageous. Through this procedure an earlier drug effect could be expected and the increase of thyroid hormones after finishing lithium therapy will be suppressed. In the own material severe side effects are not demonstrable.

The use of lithium in the treatment of thyrotoxicosis.
Temple R, Berman M, Robbins J, Wolff J.
Since lithium has been shown to inhibit release of iodine from the thyroid, we have investigated its therapeutic potential in thyrotoxicosis. Eight detailed (131)I kinetic studies were performed on seven thyrotoxic women and data was analyzed using a computer program. Lithium at serum levels of about 1 mEq liter decreased the loss of (131)I from the thyroid, led to a fall in serum (131)I levels and diminished urinary (131)I excretion. Computer simulation of the lithium effect required, in every case, that lithium inhibit hormonal and nonhormonal thyroid iodine release. In five cases a second lithium effect was required for a satisfactory fit of the model solution with observed data: namely, an inhibition of hormone disappearance from serum. NEITHER INHIBITION OF RELEASE NOR OF HORMONE DISAPPEARANCE SEEMED TO BE AFFECTED BY METHIMAZOLE (RELEASE: 52% decrease without methimazole, 60% with methimazole; hormone disappearance: approximately 60% decrease in both). When Li(+) was discontinued, recovery of the iodine release rate and hormone disappearance rate over the observed time span was variable, ranging from no recovery to rates that exceeded pre-Li(+) values. When Li(+) is used alone its effect on serum hormone levels is diminished due to continued accumulation of iodide by the thyroid. Thus, serum thyroxine-iodine levels fell 21-30% in 6-8 days in patients who did not receive methimazole and 15-67% in the methimazole-treated subjects. For prolonged therapy, therefore, a thiocarbamide drug must be used in conjunction with Li(+). The similarity of inhibition of iodine release from the thyroid produced by Li(+) and iodides is discussed.

Lithium carbonate in the treatment of thyrotoxicosis. A controlled trial.
Kristensen O, Andersen HH, Pallisgaard G.
Of 24 patients with newly diagnosed thyrotoxicosis, 13 were randomly selected for treatment with methimazole 40 mg per day, and 11 for treatment with lithium carbonate in such doses that the serum lithium lay between 0-5 and 1-3 meq. per litre. The lithium treatment brought about a fall in serum-thyroxine iodine (T4I) of 27.0%, and in the free-thyroxine index (F.T.I.) of 38.1% after 10 days. A comparison of the two patient groups with regard to the fall in F.T.I. after 3 and 10 days showed no statistically significant difference; similarly the calculated confidence limits appeared to exclude any difference of clinical importance. 8 of the 11 patients subjected to lithium treatment had side-effects, so that the general condition, which was already affected by the hyperthyroidism, was worsened. It is concluded that lithium cannot be considered superior to thiocarbamides for the rapid control of thyrotoxicosis.

We describe four patients treated with lithium for the control of hyperthyroidism. Conventional therapy with propylthiouracil and/or methimazole was tried initially, but the patients were either unresponsive or developed side effects during the drug administration. Within several days of reaching therapeutic levels of lithium, a euthyroid state was achieved in three of the four cases. Our observations support the use of lithium as an alternative antithyroid drug in the treatment of hyperthyroidism in certain defined indications, a clinical use that is not widely known.

Thyroid clinic of a regional hospital in Hong Kong.
PATIENTS:Thirteen patients with thyrotoxicosis pending therapy with radioiodine or surgery, in whom thionamides were contra-indicated due to adverse reactions or failure of treatment.
MAIN OUTCOME MEASURES:Free thyroxine levels, time to euthyroidism, and side-effects of lithium.
RESULTS:A satisfactory response, defined as a fall by 40% or more in free thyroxine levels and clinical improvement, was achieved in eight patients within 1 to 2 weeks of lithium therapy. In four others, response occurred in 3 to 5 weeks. Response was slow and inadequate in one patient due to ‘escape’. The median dosage of lithium was 750 mg daily, with a range of 500 to 1500 mg daily. The median serum lithium level was 0.63 mmol/L. Lithium toxicity was observed in one patient.
CONCLUSIONS:A relatively low dose of lithium offers a safe and effective alternative means of controlling thyrotoxicosis in patients who cannot tolerate or do not respond to thionamides.

Iodine treatment of iodine-induced thyrotoxicosis.
Boehm TM, McLain J, Burman KD, deShazo R, Wartofsky L.
A 62-year-old female who had received prolonged iodine therapy for asthma presented with severe thyrotoxicosis and severe asthma. Her history, elevated serum thyroxine and triiodothyronine, low 131I uptake, and elevated intrathyroidal iodine content by fluorescent scan were most consistent wiht a diagnosis of iodine-induced thyrotoxicosis (IITT). The clinical course of her thyrotoxicosis was protracted, and in spite of its etiologic role in the precipitaton of thyrotoxicosos, iodine was therapeutically efficacious, although combined treatment with methimazole was required to ultimately restore euthyroidism. Therapy with lithium was also employed but appeared to be only transiently effective and combined no additional decrement in serum T4 than that seen with iodine alone. The case exemplifies the heterogeneity of what is considered “iodine-induced” thyrotoxicosis, the complexities inherent in establishing a diagnosis of IITT, and the use of other rapid acting pharmacologic agents in IITT when beta blockade is contraindicated by asthma.

Graves’ Disease is a type of hyperthyroidism that is due to the production of autoantibodies against the TSH receptor on the follicular epithelial cells. These antibodies mimic the effects of TSH and cause overproduction and release of thyroid hormone. The epithelial cells in this patient no longer surround round follicles of colloid. Instead, these follicles are disappearing and the colloid is becoming depleted. Compare to normal thyroid.
