ABSTRACT
Se presentan 3 pacientes que consultaron a la sección de endocrinología de la Fundación Santa Fe de Bogota para evaluación de la funcion tiroidea. Todos tenian diagnostico de hipotiroidismo de varios años de evolución, tratado con medicamentos anorexiantes serotoninergicos tipo fenfluramina o dexfenfluoramina. Los tres pacientes fueron de sexo femenino, de 58, 34 y 44 años de edad, ninguna tenia historia de enfermedad valvular. El paso fue de 59,61 y 69 Kg. con indices de masa corporal de 23, 24 y 26 Kg/m respectivamente. Las pacientes 1 y 2 recibieron fenfluoramina (60 mg/dia) por nueve y siete años respectivamente y la 3 recibio dexfenfluoramina por diez meses a dosis de 30 mg diarios por tener antecedentes de sobrepeso u obesidad. Se confirmaron en las pacientes 1 y 3 insuficiencia aortica y mitral y en la 2 insuficiencia aortica, mitral y tricuspidea. La apciente 1 requirio remplazo valvular aortico y mitral y la patologia evidencio cambios compatibles con sindrome carcinoide. Comclusiones: los tres caso sugieren asociacion del uso de fenfluoramina y dexfenfluoramina a largo y mediano plazo, con daños valvulares e insuficiencias mitral, aortica y tricuspidea. El estudio histopatologico similar al sindrome carcinoide en uno de los casos, reafirma la sospecha

Oubain sensitive and insensitive adenosine triphosphatase showed decrease in their activities in the polymorphonuclear leukocytes of obese patients while the activity of acetylcholinesterase was found to be increased significantly. The contents of sodium, potassium and magnesium were found to be significantly decreased in polymorphonuclear leukocytes of obese patients. Polymorphonuclear leukocytes obtained from treated obese patients showed considerable restoration.

A prospective, randomised case-control trial of an anorectic drug, fenfluramine was conducted on 30 patients of simple obesity. The study revealed that the drug was well tolerated, non-toxic and effective in reducing the body weight and normalising the thyroid profile. Reduction in body weight, rise in serum thyroxine (T4) and fall in serum triiodothyronine (T3) was highly significant (p less than 0.01) in drug treated group as compared to controls (p less than 0.05) after 12 weeks of therapy. There was also fall in serum thyroid stimulating hormone (TSH) levels but without any statistical significance.

Trata-se de uma revisäo da literatura, visando determinar a validade do uso da farmacoterapia na síndrome de autismo. É avaliada também a metodologia clínica dos trabalhos originais sobre o assunto, na tentativa de se exprimir um posicionamento bem próximo da verdade atual sobre farmacoterapia nesta síndrome. Os diferentes autores propöem a utilizaçäo de diversos fármacos (triiodotironina, piridoxina, sulpiride, drogas antipsicóticas e fenfluramine) no autismo. Entretanto, somente o haloperidol demonstrou efetivamente em estudes clínicos bem conduzidos; sendo que sua eficácia restringe-se à diminuiçäo de sintomas alvo, especialmente isolamento e estereotipias.
