Agents that are used to treat hyperthyroidism by reducing the excessive production of thyroid hormones.
A thioureylene antithyroid agent that inhibits the formation of thyroid hormones by interfering with the incorporation of iodine into tyrosyl residues of thyroglobulin. This is done by interfering with the oxidation of iodide ion and iodotyrosyl groups through inhibition of the peroxidase enzyme.
A thiourea antithyroid agent. Propythiouracil inhibits the synthesis of thyroxine and inhibits the peripheral conversion of throxine to tri-iodothyronine. It is used in the treatment of hyperthyroidism. (From Martindale, The Extra Pharmacopeoia, 30th ed, p534)
An imidazole antithyroid agent. Carbimazole is metabolized to METHIMAZOLE, which is responsible for the antithyroid activity.
A common form of hyperthyroidism with a diffuse hyperplastic GOITER. It is an autoimmune disorder that produces antibodies against the THYROID STIMULATING HORMONE RECEPTOR. These autoantibodies activate the TSH receptor, thereby stimulating the THYROID GLAND and hypersecretion of THYROID HORMONES. These autoantibodies can also affect the eyes (GRAVES OPHTHALMOPATHY) and the skin (Graves dermopathy).
Hypersecretion of THYROID HORMONES from the THYROID GLAND. Elevated levels of thyroid hormones increase BASAL METABOLIC RATE.
A hypermetabolic syndrome caused by excess THYROID HORMONES which may come from endogenous or exogenous sources. The endogenous source of hormone may be thyroid HYPERPLASIA; THYROID NEOPLASMS; or hormone-producing extrathyroidal tissue. Thyrotoxicosis is characterized by NERVOUSNESS; TACHYCARDIA; FATIGUE; WEIGHT LOSS; heat intolerance; and excessive SWEATING.
Autoantibodies that bind to the thyroid-stimulating hormone (TSH) receptor (RECEPTORS, THYROTROPIN) on thyroid epithelial cells. The autoantibodies mimic TSH causing an unregulated production of thyroid hormones characteristic of GRAVES DISEASE.
A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.
The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.
Blood tests used to evaluate the functioning of the thyroid gland.
A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA.
A glycoprotein hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Thyrotropin stimulates THYROID GLAND by increasing the iodide transport, synthesis and release of thyroid hormones (THYROXINE and TRIIODOTHYRONINE). Thyrotropin consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the pituitary glycoprotein hormones (TSH; LUTEINIZING HORMONE and FSH), but the beta subunit is unique and confers its biological specificity.
A decrease in the number of GRANULOCYTES; (BASOPHILS; EOSINOPHILS; and NEUTROPHILS).
Pathological processes involving the THYROID GLAND.
Occurs in seeds of Brassica and Crucifera species. Thiouracil has been used as antithyroid, coronary vasodilator, and in congestive heart failure although its use has been largely supplanted by other drugs. It is known to cause blood dyscrasias and suspected of terato- and carcinogenesis.
Cell surface proteins that bind pituitary THYROTROPIN (also named thyroid stimulating hormone or TSH) and trigger intracellular changes of the target cells. TSH receptors are present in the nervous system and on target cells in the thyroid gland. Autoantibodies to TSH receptors are implicated in thyroid diseases such as GRAVES DISEASE and Hashimoto disease (THYROIDITIS, AUTOIMMUNE).
A T3 thyroid hormone normally synthesized and secreted by the thyroid gland in much smaller quantities than thyroxine (T4). Most T3 is derived from peripheral monodeiodination of T4 at the 5' position of the outer ring of the iodothyronine nucleus. The hormone finally delivered and used by the tissues is mainly T3.
Inflammatory disease of the THYROID GLAND due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-CELLS and thyroid AUTOANTIBODIES. The clinical signs can range from HYPOTHYROIDISM to THYROTOXICOSIS depending on the type of autoimmune thyroiditis.
Natural hormones secreted by the THYROID GLAND, such as THYROXINE, and their synthetic analogs.
Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes.
Inflammatory diseases of the THYROID GLAND. Thyroiditis can be classified into acute (THYROIDITIS, SUPPURATIVE), subacute (granulomatous and lymphocytic), chronic fibrous (Riedel's), chronic lymphocytic (HASHIMOTO DISEASE), transient (POSTPARTUM THYROIDITIS), and other AUTOIMMUNE THYROIDITIS subtypes.
Enlargement of the THYROID GLAND that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (HYPOTHYROIDISM), or hormone overproduction (HYPERTHYROIDISM). Goiter may be congenital or acquired, sporadic or endemic (GOITER, ENDEMIC).
Antibodies that react with self-antigens (AUTOANTIGENS) of the organism that produced them.
Surgical removal of the thyroid gland. (Dorland, 28th ed)
Chronic autoimmune thyroiditis, characterized by the presence of high serum thyroid AUTOANTIBODIES; GOITER; and HYPOTHYROIDISM.
A thiourea antithyroid agent that inhibits the synthesis of thyroid hormone. It is used in the treatment of hyperthyroidism.
A hemeprotein that catalyzes the oxidation of the iodide radical to iodine with the subsequent iodination of many organic compounds, particularly proteins. EC 1.11.1.8.
Compounds that contain the Cl(=O)(=O)(=O)O- structure. Included under this heading is perchloric acid and the salts and ester forms of perchlorate.
The widespread involvement of the skin by a scaly, erythematous dermatitis occurring either as a secondary or reactive process to an underlying cutaneous disorder (e.g., atopic dermatitis, psoriasis, etc.), or as a primary or idiopathic disease. It is often associated with the loss of hair and nails, hyperkeratosis of the palms and soles, and pruritus. (From Dorland, 27th ed)
A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.
A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.
An intense itching sensation that produces the urge to rub or scratch the skin to obtain relief.

Alternating antineutrophil cytoplasmic antibody specificity: drug-induced vasculitis in a patient with Wegener's granulomatosis. (1/466)

We describe a patient who presented with Wegener's granulomatosis associated with antineutrophil cytoplasmic antibodies (ANCA) directed against proteinase 3 (PR3) with a cytoplasmic immunofluorescence pattern (cANCA), whose ANCA type changed to antimyeloperoxidase antibodies with a perinuclear immunofluorescence pattern (pANCA) when treated with propylthiouracil, and changed back to anti-PR3 antibodies with cANCA after the medication was discontinued. The patient developed flares of vasculitis symptoms associated with rises in either type of ANCA. Tests for antimyeloperoxidase ANCA were repeatedly negative before the drug was started, strongly implicating the drug as the cause of the episode. This case demonstrates that patients with idiopathic ANCA-positive vasculitis may quickly develop a superimposed drug-associated ANCA-positive vasculitis. Iatrogenic vasculitis should be suspected when a patient with idiopathic vasculitis with one type of ANCA develops the other type of ANCA.  (+info)

Screening methods for thyroid hormone disruptors. (2/466)

The U.S. Congress has passed legislation requiring the EPA to implement screening tests for identifying endocrine-disrupting chemicals. A series of workshops was sponsored by the EPA, the Chemical Manufacturers Association, and the World Wildlife Fund; one workshop focused on screens for chemicals that alter thyroid hormone function and homeostasis. Participants at this meeting identified and examined methods to detect alterations in thyroid hormone synthesis, transport, and catabolism. In addition, some methods to detect chemicals that bind to the thyroid hormone receptors acting as either agonists or antagonists were also identified. Screening methods used in mammals as well as other vertebrate classes were examined. There was a general consensus that all known chemicals which interfere with thyroid hormone function and homeostasis act by either inhibiting synthesis, altering serum transport proteins, or by increasing catabolism of thyroid hormones. There are no direct data to support the assertion that certain environmental chemicals bind and activate the thyroid hormone receptors; further research is indicated. In light of this, screening methods should reflect known mechanisms of action. Most methods examined, albeit useful for mechanistic studies, were thought to be too specific and therefore would not be applicable for broad-based screening. Determination of serum thyroid hormone concentrations following chemical exposure in rodents was thought to be a reasonable initial screen. Concurrent histologic evaluation of the thyroid would strengthen this screen. Similar methods in teleosts may be useful as screens, but would require indicators of tissue production of thyroid hormones. The use of tadpole metamorphosis as a screen may also be useful; however, this method requires validation and standardization prior to use as a broad-based screen.  (+info)

Risk of iodine-induced thyrotoxicosis after coronary angiography: an investigation in 788 unselected subjects. (3/466)

In this study, the risk of iodine-induced thyrotoxicosis in unselected patients from an iodine-deficient area was investigated. The patients were consecutively enrolled. Thyroid hormone values and urinary iodine excretion were determined before, as well as 1, 4 and 12 weeks after iodine contamination by coronary angiography. Two of 788 unselected patients developed hyperthyroidism within 12 weeks. The two patients did not belong to a risk group for iodine-induced thyrotoxicosis (i.e. old people, patients with goiter or possible thyroid autonomy, low TSH). Both patients had normal TSH levels at baseline and ultrasound of the thyroid was without evidence of nodules. The study shows that in euthyroid unselected patients from an iodine-deficient area short-term iodine contamination by contrast media rarely leads to hyperthyroidism. On account of these facts, prophylactic therapy, e.g. by perchlorate or thiamazole, is not generally recommended, because the risk of side-effects is perhaps even greater than the risk of iodine-induced thyrotoxicosis.  (+info)

Identification of thyroid hormone residues on serum thyroglobulin: a clue to the source of circulating thyroglobulin in thyroid diseases. (4/466)

Thyroglobulin (Tg) present in the serum of normal individuals and patients with thyroid disorders could be partly newly synthesized non-iodinated Tg and partly Tg containing iodine and hormone residues originating from the lumen of thyroid follicles. With the aim of examining the contribution of the latter source of Tg to the elevation of serum Tg concentration in thyroid pathophysiological situations, we devised a procedure to identify thyroxine (T4) and tri-iodothyronine (T3) residues on Tg from unfractionated serum. A two-step method, basedon (i)adsorption of Tg on an immobilized anti-human Tg (hTg) monoclonal antibody (mAb) and (ii)recognition of hormone residues on adsorbed Tg by binding of radioiodinated anti-T4 mAb and anti-T3 mAb, was used to analyze serum Tg from patients with either Graves' disease (GD), subacute thyroiditis (ST) or metastatic differentiated thyroid cancer (DTC). Purified hTg preparations with different iodine and hormone contents were used as reference. Adsorption of purified Tg and serum Tg on immobilized anti-hTg mAb ranged between 85 and 90% over a wide concentration range. Labeled anti-T4 and anti-T3 mAbs bound to adsorbed purified Tg in amounts related to its iodine content. Tg adsorbed from six out of six sera from ST exhibited anti-T4 and anti-T3 mAb binding activities. In contrast, significant mAb binding was only observed in one out of eight sera from untreated GD patients and in 1 out of 13 sera from patients with DTC. The patient with DTC, whose serum Tg contained T4 and T3, represented a case of hyperthyroidism caused by a metastatic follicular carcinoma. In conclusion, we have identified, for the first time, T4 and T3 residues on circulating Tg. The presence of Tg with hormone residues in serum is occasional in GD and DTC but is a common and probably distinctive feature of ST.  (+info)

Improved suppression by dietary taurine of the fecal excretion of bile acids from hypothyroid rats. (5/466)

The effect of dietary taurine, 2-aminoethanesulfonic acid, on hypercholesterolemia caused by thiouracil-induced hypothyroidism was investigated in hypothyroid rats. Serum total- and HDL-cholesterol were significantly increased, and the excretion of fecal bile acids was significantly decreased. Taurine did not change the hypercholesterolemia, but significantly recovered the excretion of bile acids.  (+info)

Effects of oral propylthiouracil treatment on nitric oxide production in rat aorta. (6/466)

The effects of oral propylthiouracil (PTU) treatment on vascular nitric oxide (NO) production were studied in the rat aorta. Rats were fed a standard low fat diet with or without 0.1% PTU, for 2 or 4 weeks, or for 2 weeks with additional thyroxine injections. Concentration response curves were then constructed to phenylephrine (PE) in both endothelium-intact and denuded aortic rings from these animals and after incubation with 0.1 mM L-N(G)nitroarginine (L-NOARG). In addition, expression of nitric oxide synthase (NOS) was analysed in sections of aorta from PTU-treated and control rats using rabbit polyclonal antibodies to both inducible NOS (iNOS) and endothelial NOS (eNOS). Oral PTU treatment resulted in a significant reduction in both the maximum response (control, 0.53+/-0.02; 2 week PTU, 0.20+/-0.07; 4 week PTU, 0.07+/-0.02 g mg(-1)) and vessel sensitivity (EC50 values: control, 9.10x10(-8)+/-0.67; 2 week PTU, 7.45x10(-7)+/-1.15; 4 week PTU, 9.73x10(-7)+/-0.45 M) to PE in endothelium-intact vessel rings, as compared to controls (P<0.05). Both endothelial removal and incubation with L-NOARG restored the maximum response after 2, but not 4 weeks, although, in general, vessel sensitivity was not altered by either treatment. Vessels from PTU-treated rats given thyroxine injections showed no significant differences between any of the dose response curve parameters. Immunohistochemical analysis suggested that labelling for eNOS may be increased after PTU treatment as compared to control animals, whereas iNOS antibody immunoreactivity was not different between the two groups. These results suggest that the hyporesponsiveness to PE observed after oral PTU treatment is, in part, due to enhanced nitric oxide (NO) production by the endothelium, and demonstrate for the first time that thyroid hormones may play a role in the regulation of eNOS activity in the rat aorta.  (+info)

Remission of insulin autoimmune syndrome in a patient with Grave's disease by treatment with methimazole. (7/466)

The patient, a 24-year-old man, had suffered from hunger, sweating, tachycardia and palpitation for three years. He was diagnosed as having Graves' disease (GD) and treated with methimazole (MMI) for 3 months. He noted that palpitation and perspiration seemed to particularly occur when he was hungry, and thus he was examined to determine whether these symptoms were caused by hypoglycemia. As a markedly elevated immunoreactive insulin level and the presence of insulin antibody in serum were found, he was diagnosed as having insulin autoimmune syndrome (IAS). HLA typing revealed the patient to be positive for group Bw62/Cw4/DR4, which is reportedly a specific HLA type in MMI-treated euthyoroid GD patients with IAS. In spite of the continuation of MMI treatment, the % binding of IRI decreased and the hypoglycemic episode disappeared. In contrast to the previously reported MMI induced IAS in GD cases, MMI is unlikely to have exacerbated IAS in the present case, although his HLA combination is identical to that of the previous cases.  (+info)

Hypercalcemia accompanied by hypothalamic hypopituitarism, central diabetes inspidus and hyperthyroidism. (8/466)

We present here a case of prominent hypercalcemia accompanied by hypothalamic tumor and Graves' disease. A 24-year-old man with hypothalamic tumor showed hypopituitarism, central diabetes inspidus (DI) and hyperthyroidism. Nausea, loss of thirst and appetite, and general fatigue were found with the unveiling of hypercalcemia and hypernatremia. Parathyroid hormone (PTH) and 1alpha-dihydroxyvitamin D levels were suppressed with a normal range of PTH-related protein values. One-desamino-(8-D-arginine)-vasopressin (DDAVP) and half-saline administration normalized hypernatremia, while hypercalcemia was still sustained. Administration of cortisone acetate and thiamazole reduced the elevated serum Ca level. In the present case, concurrent hyperthyroidism was assumed to accelerate skeletal mobilization of calcium into the circulation. Hypocortisolism and central DI was also considered to contribute, to some extent, to the hypercalcemia through renal handling of Ca.  (+info)

An antithyroid agent is a hormone antagonist acting upon thyroid hormones. The main antithyroid drugs are carbimazole (in the UK), methimazole (in the US), and propylthiouracil/PTU. A less common antithyroid agent is potassium perchlorate. In Graves disease, treatment with antithyroid medications must be given for six months to two years, in order to be effective. Even then, upon cessation of the drugs, the hyperthyroid state may recur. Side effects of the antithyroid medications include a potentially fatal reduction in the level of white blood cells. A randomized control trial testing single dose treatment for Graves found methimazole achieved euthyroid state more effectively after 12 weeks than did propylthyouracil (77.1% on methimazole 15 mg vs 19.4% in the propylthiouracil 150 mg groups). But generally both drugs are considered equivalent. A study has shown no difference in outcome for adding thyroxine to antithyroid medication and continuing thyroxine versus placebo after antithyroid ...
Description of disease Drug, antithyroid. Treatment Drug, antithyroid. Symptoms and causes Drug, antithyroid Prophylaxis Drug, antithyroid
The primary goals of treatment for hyperthyroidism are to eliminate excess thyroid hormone and minimize the long-term consequences.9 Treatments include radio-active iodine, antithyroid medications (propylthiouracil [PTU], methimazole [MMI]), and surgery.2,8-10 Beta-blockers are sometimes added to provide symptomatic relief.9,13,15. Radioactive Iodine Therapy (RIT): The usual dose for RIT ranges from 5 to 15 mCi of 131I. In general, higher dosages are required for patients who have large goiters or low radioiodine uptake, or who have been pretreated with antithyroid drugs.15,16. Because the thyroid needs iodine to produce hormones, the radioiodine goes into the thyroid cells and, over time, overactive thyroid cells are destroyed. The thyroid gland shrinks, and in several weeks to months, hyperthyroid symptoms gradually diminish.16 RIT may increase the risk of new or worsened symptoms of Graves ophthalmopathy. This adverse effect is usually mild and temporary, but the therapy may not be utilized ...
1. Diagnosis:. Clinical presentation and initial biochemical evaluation should make the diagnosis in most cases.However, a case of a patient with no goiter and no apparent eye disease may need more testing.The thyroid stimulating antibody TRAb, iodine uptake, or ultrasound can be used. Thyroid scan is indicated if toxic adenoma or toxic multinodular goiter is suspected.. 2. Use TRAb to control antithyroid drug therapy. 13% of patients have reactions. Minor allergic reactions to serious reactions that include a loss of white blood cells, blood vessel disease, and liver toxicity... TRAb levels should be measured before the end of antithyroid drug therapy to identify patients with a higher chance of remission.1. Patients with high TRAb could opt for Surgery or radioiodine.. 3. Safety of long-term antithyroid drug therapy makes it more accepted to be on antithyroid drugs long-term.. Methimazole doses of 2.5 mg/d to 10mg/d is safe and effective and had better outcomes and fewer side effects than ...
Purpose Whereas antithyroid drugs (ATD) are the preferred treatment modality for Graves hyperthyroidism (GH), there is still controversy about the optimal regimen for delivering ATD. To evaluate whether Block and Replace (B + R) and Titration (T) regimes are equivalent in terms of frequency of euthyroidism and Graves Orbitopathy (GO) during ATD therapy. Methods A prospective multicentre observational cohort study of 344 patients with GH but no GO at baseline. Patients were treated with ATD for 18 months according to B + R or T regimen in line with their institutions policy. Results Baseline characteristics were similar in both groups. In the treatment period between 6 and 18 months thyrotropin (TSH) slightly increased in both groups, but TSH was on average 0.59 mU/L (95% CI 0.27-0.85) lower in the B + R group at all time points (p = 0.026). Serum free thyroxine (FT4) remained stable during the same interval, with a tendency to higher values in the B + R group. The point-prevalence of ...
No single treatment is best for all patients with hyperthyroidism. The appropriate choice of treatment will be influenced by your age, the type of hyperthyroidism that you have, the severity of your hyperthyroidism, other medical conditions that may be affecting your health, and your own preference. It may be a good idea to consult with an endocrinologist who is experienced in the treatment of hyperthyroid patients. If you are unconvinced or unclear about any thyroid treatment plan, a second opinion is a good idea.. Antithyroid Drugs: Drugs known as antithyroid agents-methimazole (Tapazole®) or in rare instances propylthiouracil (PTU)-may be prescribed if your doctor chooses to treat the hyperthyroidism by blocking the thyroid glands ability to make new thyroid hormone. Methimazole is presently the preferred one due to less severe side-effects. These drugs work well to control the overactive thyroid, and do not cause permanent damage to the thyroid gland. In about 20% to 30% of patients with ...
Taking antithyroid drugs (ATDs) during the first trimester of pregnancy is associated with an increased risk for birth defects, particularly for women receiving prescriptions for methimazole (MMI) or both MMI and propylthiouracil (PTU). The findings are published in Annals of Internal Medicine.
Infants born to women who received antithyroid drugs for Graves disease during the first trimester of pregnancy had an increased risk for congenital malformations, a study found.
Treatment for GD is focused in three main directions, decrease production, inactivation, or removing of the thyroid. Treatment one uses antithyroid drugs to lower T3 and T4 production, this treatment option is the lease invasive and potential will solve the problem. The theory of antithyroid treatment is to lower the production of hormones to normal levels, causing the thyroid to continue normal production after antithyroid treatment is completed. Hyperthyroidism may resume after treatment, which makes this treatment option unsuccessful. Inactivation of the thyroid is the second treatment option; thyroid hormone production is discontinued after radioactive iodine destroys thyroid function. Replacement thyroid drug therapy is then provided to the patient in synthetic form of thyroid hormone. Thyroid removal is the final treatment available, preventing all production of thyroid hormones, also resulting in synthetic drug replacement therapy ...
Conclusion The presentation of case 1 is well recognised in the literature in adult patients with established thyroid disease. In case 2 our patient developed focal status epilepticus which has not been recognised as a feature of Hashimotos encephalitis in the literature. He is also responding to a new form of immunomodulation medication which has previously never been described; most cases in the literature have used azathioprine as a second-line agent. Both patients had an encephalopathy related to antithyroid antibodies but their history, signs and symptoms highlight the spectrum of presentations that these patients can have as well as the varied clinical response to treatment. The authors feel presenting the above cases with an overview of current literature will aid clinical practice and would be grateful for the opportunity to highlight the spectrum if disease associated with antithyroid antibodies. ...
The British Thyroid Foundation is a UK charity dedicated to supporting people with thyroid disorders and helping their families and people around them to understand the condition.
The most commonly used antithyroid drugs are Propylthiouracil (P.T.U.) and Tapazole (Methimazole). These drugs act to prevent the thyroid gland from manufacturing thyroid hormone, and thus the symptoms of hyperthyroidism will gradually subside.. You will probably begin to feel better within two weeks, you will feel a difference by six weeks, and feel well in 10-14 weeks. You will probably take the medication for 6-12 months. Your doctor will check at six months, nine months and twelve months approximately, to see if P.T.U. is still needed. If your thyroid gland now functions normally, your family doctor will still check you periodically to be sure that your thyroid hormone level (T4) remains within the normal range or just above (normal T4 range - 50-165nmol/L). Most patients feel better with a T4 level in the upper half of normal (110-165nmol/L).. If taking antithyroid drugs, P.T.U. or Tapazole, and you develop a rash, itching, hives, joint pains, a fever or sore throat, stop taking the drug ...

Methimazole (MMI) and propylthiouracil (PTU) are widely used antithyroid drugs (ATD) that have been approved for the treatment of hyperthyroidism. Hepatotoxicity may be induced by these drugs, though they exert dissimilar incidence rates of hepatotoxicity and, possibly, with different underlying pathogenic mechanisms. We report the case of a 55-year-old woman with no relevant medical history diagnosed with hyperthyroidism due to Graves disease, who developed two episodes of acute hepatitis concurrent with the consecutive administration of two different ATDs, first MMI and then PTU. Given the impossibility of administering ATDs, it was decided to perform a total thyroidectomy because the patient was found to be euthyroid at that point. Pathological anatomy showed diffuse hyperplasia and a papillary thyroid microcarcinoma of 2 mm in diameter. Subsequent clinical check-ups were normal. This case suggests the importance of regular monitoring of liver function for hyperthyroid patients. Due to the ...

In our cohort of 279 patients with AAV, the overall prevalence of thyroid disease was 21.5%. The prevalence of hypothyroidism was 17.6%; this is much higher than the reported population prevalence of hypothyroidism in the United Kingdom, which is around 1%. This was particularly evident in women for whom the prevalence of hypothyroidism in our cohort was 30.8% compared to around 2% in the general population14. The prevalence of hyperthyroidism was also higher but the difference less marked, with 3.6% in our population compared to a reported population prevalence of 0.5-2.0%14. This was seemingly independent of the use of antithyroid drugs, with only 2 documented cases of previous PTU use in our series. This is similar to a previously reported prevalence of thyroid disease of 20% in 158 patients with AAV, and 38% in women with AAV, in an American case-control series; they also reported a low rate of use of antithyroid drugs (2/129 patients)9. A Swedish study reporting comorbidities in patients ...

Levothyroxine (T4) is a synthetically prepared levo isomer of thyroxine, the major hormone secreted from the thyroid gland. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form triiodothyronine which exerts a broad spectrum of stimulatory effects on cell metabolism. Thyroid hormone increases the metabolic rate of cells of all tissues in the body. In the fetus and newborn, thyroid hormone is important for the growth and development of all tissues including bones and the brain. In adults, thyroid hormone helps to maintain brain function, food metabolism, and body temperature, among other effects.

Levothyroxine (T4) is a synthetically prepared levo isomer of thyroxine, the major hormone secreted from the thyroid gland. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form triiodothyronine which exerts a broad spectrum of stimulatory effects on cell metabolism. Thyroid hormone increases the metabolic rate of cells of all tissues in the body. In the fetus and newborn, thyroid hormone is important for the growth and development of all tissues including bones and the brain. In adults, thyroid hormone helps to maintain brain function, food metabolism, and body temperature, among other effects.

Treatment. Treatment of Graves disease usually involves one of three methods, antithyroid drugs (thionamides), use of radioactive iodine, or surgery. The specific form of treatment recommended may be based upon the age of an affected individual and the degree of the illness.. The least invasive method of treating Graves disease is the use of drugs that reduce the release of thyroid hormone (antithyroid drugs). These drugs are especially preferred for the treatment of young children and pregnant women, individuals with mild cases of hyperthyroidism, or individuals in whom prompt control of hyperthyroidism is required. The most common antithyroid drug used to treat Graves disease is methimazole, which is recommended by the American Thyroid Association and the American Association of Clinical Endocrinologists as the initial treatment of choice for hyperthyroidism in children and adolescents. Propylthiouracil is sometimes used in specific instances, especially when Graves disease occurs early in ...
The treatment of hyperthyroidism is described in detail in the Hyperthyroidism brochure. All hyperthyroid patients should be initially treated with beta-blockers. Treatment options to control Graves disease hyperthyroidism include antithyroid drugs (generally methimazole [Tapazole®], although propylthiouracil [PTU] may be used in rare instances such as the first trimester of pregnancy), radioactive iodine and surgery.. Antithyroid medications are typically preferred in patients who have a high likelihood of remission (women, mild disease, small goiters, negative or low titer of antibodies). These medications do not cure Graves hyperthyroidism, but when given in adequate doses are effective in controlling the hyperthyroidism.. If methimazole is chosen, it can be continued for 12-18 months and then discontinued if TSH and TRAb levels are normal at that time. If TRAb levels remain elevated, the chances of remission are much lower and prolonging treatment with antithyroid drugs is safe and may ...

Methimazole: A thioureylene antithyroid agent that inhibits the formation of thyroid hormones by interfering with the incorporation of iodine into tyrosyl residues of thyroglobulin. This is done by interfering with the oxidation of iodide ion and iodotyrosyl groups through inhibition of the peroxidase enzyme.
Propylthiouracil (PTU) could induce antineutrophil cytoplasmic antibody (ANCA) associated vasculitis. This study aimed to investigate the inhibitory effects on MPO oxidation activity by PTU and MPO-ANCA from patients with primary microscopic potyangiitis (MPA) and PTU-induced vasculitis. IgG preparations were purified from MPO-ANCA-positive sera from seven patients with PTU-induced vasculitis and ten patients with primary MPA. The oxidation activity of MPO was measured in the presence of PTU and MPC-ANCA-positive IgG preparations from patients with PTU-induced vasculitis and primary MPA respectively. PTU could competitively inhibit the oxidation activity of MPO dose dependently. MPO-ANCA-positive IgG preparations from 6/7 patients with PTU-induced vasculitis and only 3/10 from patients with primary MPA could inhibit the MPO activity in a dose-dependent manner. In conclusions, the oxidation activity of MPO could be inhibited by PTU and PTU-induced MPC-ANCA in a dose-dependent manner, which might ...

SUPPRESSED TSH WITHOUT CLEAR CAUSE? TREATMENT?. QUESTION-I would be thankful if you could kindly guide me on this clinical situation I come across so often.. Patients of various age groups are frequently referred with persistent subclinical hyperthyroidism. TSH suppression can be mild or less than 0.2 mIU/l. Patients may be asymptomatic or having symptoms that may or may not be secondary to subclinical hyperthyroidism.. On many occasions I do not find any underlying cause, thyroid antibodies including TSH receptor antibodies are negative, pertechnetate thyroid uptake scans are normal with no hyper functioning nodules are demonstrated.. How should these patients be managed. Which of these patients are candidates for antithyroid medications. How long should they be treated.. Young or old, should these patients have bone densitometry scan in order to decide about treatment.. Is there any role of urine iodine measurement and replacement if found low rather than initiating patients on antithyroid ...
|p|Graves disease is an autoimmune disease that affects the thyroid gland. The thyroid produces hormones called T3 and T4, which help regulate the bodys use of energy. With Graves disease, the body produces too much of these hormones, which in turn causes body functions like heart rate and food metabolism to speed up. Its an autoimmune disease because it occurs because the immune system mistakenly attacks part of the body. |/p||p||b|Symptoms of Graves Disease|/b||/p||p|The overactive thyroid caused by Graves disease can lead to a number of problems. Common issues include a rapid heartbeat, trouble sleeping, nervousness, irritability and trembling hands. People with Graves disease can also develop a goiter, or enlarged thyroid, and they might see their skin thin out and their hair get brittle. Other signs of Graves disease included unexplained weight loss, weak muscles and frequent bowel movements. Graves disease can also cause serious eye issues, including swelling, inflammation and bulging of
We usually treat Graves disease with medication first. There are 2 types of medications, which are beta blockers and antithyroid medications. Each one works differently, so we will talk with you about which one is best for your child and how long your child should take the medication.. The first type of medication is called a beta blocker. Beta blockers are used to treat faster heart rate or increased blood pressure. They typically do not affect how much thyroid hormone the thyroid releases.. The second type of medication is called methimazole. Methimazole is used to control how much thyroid hormone the thyroid releases. Children can usually take methimazole with little trouble, but it can have rare, but possibly serious side effects. Minor (less serious) side effects include a metallic taste in the mouth, allergic reactions with rashes and itching and joint pain. Major (rare, but serious) side effects include liver problems, rash and a lower numbers of white blood cells in the body. This can ...
When people think of fluoride being prescribed for medicinal purposes, they generally think of fluoride supplementation to reduce tooth decay. Fluoride, however, has also been prescribed as a drug to reduce the activity of the thyroid gland. Up through the 1950s, doctors in Europe and South America prescribed fluoride to reduce thyroid function in patients with over-active thyroids (hyperthyroidism). (Merck Index 1968). Doctors selected fluoride as a thyroid suppressant based on findings linking fluoride to goitre, and, as predicted, fluoride therapy did reduce thyroid activity in the treated patients. (McClaren 1969; Galletti 1958; May 1937). Moreover, according to clinical research, the fluoride dose capable of reducing thyroid function was notably low - just 2 to 5 mg per day over several months. (Galletti & Joyet 1958). This dose is well within the range (1.6 to 6.6 mg/day) of what individuals living in fluoridated communities are now estimated to receive on a regular basis. (DHHS ...

The thyroid gland produces thyroid hormone (TH) that controls your bodys energy production and consumption.. This hormone helps regulate a variety of body processes including heart rate, body temperature and how quickly you burn calories. When too much or too little hormone is generated, your health is negatively affected. Hyperthyroidism is the name given to a disorder that is the result of too much TH hormone. This causes the metabolism to speed up, leading to rapid or irregular heartbeat, anxiety, irritability, nervousness, fatigue, heat intolerance, excessive sweating, tremors, weight loss and increased bowel movements. Hyperthyroidism can be caused by an autoimmune disorder known as Graves disease, nodules, goiter, inflammation of the thyroid gland and too much iodine. The condition is usually treated with drugs such as beta-blockers, antithyroid medications like methimazole, radioactive iodine or surgery. When the opposite occurs and too little TH hormone is produced, the metabolism ...

Anti-thyroid treatments - Lifelong treatment with antithyroid medications such as methimazole (can be given as a pil, liquid, or transdermal lotion) or a iodine restricted diet can be effective. Sometimes,however, they lose efficacy over time.. Surgical removal - The thyroid glands can be surgically removed, however this can result in hypothyroidism (low thyroid hormone) which may require medication. Complications can also ensue from the removal of the parathyroid gland which regulates calcium balance in the body. Radioactive iodine treatment - Many cats respond well to treatment with radioactive iodine. The isotope I131 is injected intravenously and effectively targets the thyroid tissue, rendering the abnormal tissue inactivated. While this can be extremely effective, it does require hospitalization and isolation. until the patient is no longer considered radioactive ...
Tapazole: Methimazole belongs to the class of medications called antithyroid medications. It is used to treat hyperthyroidism (overactive thyroid gland). It prevents the thyroid gland from over-producing thyroid hormone, but does not interfere with the actions of thyroid hormone. It may take weeks to months before methimazole has its full effect on the symptoms of overactive thyroid (e.g., palpitations, sweating). During this time period, other medications may be used to control these symptoms.
The effect of treatment with propylthiouracil early in life (PTU; 8 mg k-1 day-1, ip, from day 17 of gestation to postnatal day 42) on the susceptibility of the cerebral cortex to spreading depression (SD) was studied in 13 adult Wistar rats (90-100 days of age). Ten animals injected with Ringer solution served as control. Adult PTU-treated rats displayed a significant (P | 0.05) reduction in body weight (mean +/- SD: 139.9 +/- 28.9 g vs 304.9 +/- 42.8 g) as well as wet brain weight (1.39 +/- 0.12 g vs 1.86 +/- 0.13 g) and dry brain weight (247.3 +/- 24.2 mg vs 359.4 +/- 30.1 mg). Their thyroid glands presented histological changes indicative of hypofunction and SD velocity of propagation was significantly reduced all along the 6 h of the recording session (mean +/- SD ranges: 1.90 +/- 0.46 to 2.52 +/- 0.68 mm/min vs 3.49 +/- 0.57 to 3.71 +/- 0.55 mm/min). The results indicate that PTU early in life was effective in producing hypothyroidism and that in this situation cortical susceptibility to SD is

Radioactive iodine- Radioiodine is now more widely used in the UK, as has previously happened elsewhere, although it is contraindicated in pregnancy and while breast-feeding. Iodine-131 in an empirical dose (usually 200-500 MBq), accumulates in the thyroid and destroys the gland by local radiation - though it takes several months to be fully effective. Strict radiation safety rules apply in the UK and may be inconvenient or disconcerting for some patients. Patients must be rendered euthyroid before treatment though they have to stop antithyroid drugs at least 4 days before radioiodine, and not recommence until 3 days after radioiodine (many patients who are well controlled before radioactive iodine do not need to restart at all). Risk of carcinogenesis has been long debated, but it is now clear that overall cancer incidence and mortality are not increased after radioactive iodine (and indeed are significantly reduced in some studies) but the risk of thyroid cancer is significantly increased ...
Graves disease is an autoimmune disease. The immune system normally protects the body from germs with chemicals called antibodies. But with an autoimmune disease, it makes antibodies that attack the bodys own tissues. With Graves disease, antibodies cause the thyroid gland to make too much thyroid hormone. This is known as hyperthyroidism. Extra thyroid hormone in the bloodstream leads to the bodys metabolism being too active. It can cause problems such as low weight, fast heartbeat, high blood pressure, and heart failure.. Graves disease occurs more often in children. But it can also occur in newborn babies. If not diagnosed shortly after birth, Graves disease can be fatal to a newborn baby.. ...
