If results of thyroid relevant symptoms, thyroid morphology and important comorbidities. Melbourne and Professor Rita Horvath, Sydney antibodies, or high dose biotin (with certain thyroid assays). Propylthiouracil (6-propyl-2-thiouracil) and methimazole (1-methyl-2-mercaptoimidazole, Tapazole) are the antithyroid drugs used in the United States. First, propylthiouracil, but not methimazole or carbimazole, can block the conversion of thyroxine to triiodothyronine within the thyroid and in peripheral tissues, but this effect is not clinically important in most instances. Second, antithyroid drugs may have clinically important immunosuppressive effects. In patients taking antithyroid drugs, serum concentrations of antithyrotropin-receptor antibodies decrease with time,8 as do other immunologically important molecules, including intracellular adhesion molecule 19 and soluble interleukin-2 and interleukin-6 receptors. Chemical Structures of Propylthiouracil impair the coupling reaction in vitro, but it is uncertain and Methimazole, as Compared with Thiourea. Nevertheless, methimazole, with its oncedaily schedule, has decided advantages over propylthiouracil, including better adherence27 and more rapid improvement in serum concentrations of thyroxine and triiodothyronine. In a recent search of Internet pharmacies,42 a one-year supply of propylthiouracil (300 mg daily) was approximately $408, as compared with a one-year supply of methimazole (15 mg daily, $360; or 30 mg daily, $720). However, the disease of many patients can be controlled with smaller doses of methimazole, suggesting that the accepted potency ratio of 10:1 for methimazole as compared with propylthiouracil is an underestimate. In one randomized trial, 85 percent of patients had normal levels of thyroxine and triiodothyronine after six weeks of treatment with 10 mg of methimazole daily, as compared with 92 percent of patients receiving 40 mg daily. Antithyroid drugs are an option for initial therapy in adults with mild-to-moderate hyperthyroidism or active ophthalmopathy and are the therapy of choice for children, adolescents, and pregnant or lactating women. Radioiodine may be preferable as initial therapy for adults in the United States1 but not for those in the rest of the world. Indeed, hypothyevery two to three months and then every four to six roidism or goiter can develop if the dose is not months. After the first three to six pressed for weeks or even months, despite a normonths, follow-up intervals can be increased to malization of thyroid hormone levels, so a test of n engl j med 352;9 FurtherIf antithyroid drugs have immunosuppressive more, patients sometimes continue to have elevateffects, a higher dose or longer treatment duration ed serum triiodothyronine levels despite normal or might enhance the chances of remission. The tors for relapse after an average of three years of likelihood of relapse is increased in patients with antithyroid-drug therapy. If radioiodine therferential white-cell count should be obtained before apy is selected after a relapse, the outcome may be initiation of therapy. Most cases of agranulocytosis occur within the When used to normalize thyroid function before first 90 days of treatment, but this complication can radioiodine therapy, propylthiouracil, but not methoccur even a year or more after starting therapy. Agranulocytosis is thought to be autoimmuneAntithyroid drugs are associated with a variety of mediated, and antigranulocyte antibodies are shown minor side effects, as well as potentially life-threatby immunofluorescence83 and cytotoxicity84,85 ening or even lethal complications. Abandoning antithyroid drugs is a third opshould be obtained immediately and the drug distion, to be followed by definitive radioiodine therapy. In such cases, antiagranulocytosis (an absolute granulocyte count of thyroid drugs should be immediately discontinued less than 500 per cubic millimeter) occurred in 0. According percent of patients receiving propylthiouracil and to one report, Pseudomonas aeruginosa was the spein 0. Thirty percent of patients who had Routine monitoring of liver-function tests in papreviously received antithyroid drugs but were no tients being treated with propylthiouracil is generlonger receiving them were positive as well. The rare hepatic abnormalities associated with Other rare side effects of antithyroid drugs are methimazole and carbimazole are typical of a cholelisted in Table 1. Because of the lack of availability of propylthioOnce the thyrotoxicosis has come under conuracil in many countries, methimazole (or carbimtrol, the dose of antithyroid drug should be miniazole) is still widely used in pregnancy. If the mapregnant women should be treated with propylthiternal free thyroxine serum level is maintained at or ouracil when the drug is available. In the event of slightly above the upper limit of normal, the risk of allergy to propylthiouracil, methimazole can be subfetal hypothyroidism is negligible. The Food and Drug Administration has thyroid effects do occur, they are likely to be mild,121 categorized both propylthiouracil and methimaand follow-up studies of children exposed in utero zole as class D agents.

Au final, cette demarche pourrait permettre de calculer plus facilement le cout des maladies autoimmunes liees a une exposition a des agents physiques ou chimiques. Se pueden producir numerosas enfermedades autoinmunitarias diferentes, pero todas ellas se caracterizan por una respuesta inmunitaria inapropiada o excesiva frente a antigenos, cuyo resultado es una inflamacion cronica, destruccion de los tejidos y/o disfuncion. Hasta el momento, hay mas de 60 enfermedades con una etiologia autoinmunitaria demostrada o con una fuerte sospecha. En general, se supone que las enfermedades autoinmunitarias son relativamente poco frecuentes. Sin embargo, cuando se combinan todas estas enfermedades, la prevalencia estimada es alta (35% de la poblacion general), lo cual pone de manifiesto su importancia para la salud publica. Ademas, se tienen cada vez mas pruebas de que los mecanismos autoinmunitarios pueden influir en otras muchas enfermedades (la aterosclerosis por ejemplo). Hay factores intrinsecos (por ejemplo, la genetica, las hormonas, la edad) y factores ambientales (por ejemplo, las infecciones, la alimentacion, los medicamentos, la quimica ambiental) que pueden contribuir a la induccion, desarrollo y progresion de estas enfermedades. Se considera que los factores ambientales tienen una responsabilidad importante en su creciente prevalencia. Hay ahora pruebas epidemiologicas abundantes de la asociacion entre la exposicion ocupacional al polvo de silice cristalino (cuarzo) y el riesgo de varias enfermedades autoinmunitarias sistemicas (en particular, la esclerosis sistemica, el lupus eritematoso sistemico, la artritis reumatoide y la vasculitis sistemica de los vasos pequenos). Algunas enfermedades autoinmunitarias (por ejemplo, la enfermedad de Graves, la artritis reumatoide) se han asociado con el consumo de tabaco, en particular en los fumadores habituales, pero con otras enfermedades solo se han observado asociaciones debiles o nulas. Hay tambien algunas investigaciones sobre la influencia de factores de la alimentacion en las enfermedades autoinmunitarias. Se trata de un sector amplio que incluye la ingesta calorica, nutrientes y alimentos especificos y complementos alimentarios. La enfermedad celiaca es un ejemplo de enfermedad autoinmunitaria con una clara vinculacion con la alimentacion, en la cual una respuesta inmunitaria a proteinas especificas del trigo, la cebada y el centeno produce anticuerpos dirigidos contra la transglutaminasa de los tejidos, provocando danos en la mucosa del intestino delgado. Es muy probable que las infecciones desempenen una funcion en muchos trastornos autoinmunitarios, aunque el agente infeccioso y el mecanismo mediante el cual provoca la enfermedad pueda diferir de un trastorno a otro. La mayoria de las hipotesis que relacionan la infeccion con la autoinmunidad suponen que desempena una funcion causal directa, aunque simplemente puede servir como factor de predisposicion. Las condiciones de higiene, derivadas de una ausencia de estimulos infecciosos, pueden tener efectos en la autoinmunidad. En cambio, no hay pruebas facilmente disponibles que permitan medir el potencial de las sustancias quimicas o los factores ambientales para producir enfermedades autoinmunitarias o aumentar las existentes. Hay un gran numero de modelos animales que se han utilizado fundamentalmente para investigar mecanismos basicos y posibilidades terapeuticas para determinadas enfermedades autoinmunitarias. Los modelos de enfermedades autoinmunitarias de induccion quimica son menos comunes. Ademas, los efectos autoinmunogenicos y alergenicos de los compuestos no se suelen identificar en los estudios de toxicidad normales, en parte porque se utilizan animales exogamicos y los parametros pertinentes no se estudian. Consiste en un modelo de prueba en animales sencillo y solido que se puede utilizar para vincular reacciones directas de nodulos de linfocitos con la aplicacion local de sustancias quimicas potencialmente inmunoactivas. Sin embargo, estas valoraciones pueden predecir el potencial de sensibilizacion, pero no necesariamente el de autoinmunogenicidad de los agentes y no representan una via sistemica de exposicion. Debido a la carga de las enfermedades autoinmunitarias a nivel individual y colectivo, la evaluacion del riesgo con respecto a este grupo de enfermedades adquiere una importancia especial. Autoimmunity and autoimmune disease Autoimmune mechanisms underline many diseases, some organ-specific, others systemic in distribution. Thus the body must establish self-tolerance mechanisms, to distinguish between self and non-self determinants, so as to avoid autoreactivity (see Chapter 7). The selfrecognition mechanisms are no exception, and a number of disease have been identified in which there is autoimmunity, due to copious production of autoantibodies and autoreactive T cells. Among the autoimmune diseases, thyroiditis has been particularly well-studied, and many of the aspects discussed in this chapter will draw upon our knowledge of it. It is a disease of the thyroid which is most common in middle-aged women and often lead to formation of a goiter and hypothyroidism. Buy phenazopyridine online now.
