ABSTRACT

Se describe el caso de una mujer de 57 años de edad, con diagnóstico de síndrome de Wolf Parkinson White, en tratamiento con amiodarona 200 mg/día; que acudió por presentar palpitaciones, fatiga y aumento de sueño. Al examen físico no se encontró bocio, pero los reflejos osteotendinosos estaban prolongados. Los exámenes auxiliares mostraron TSH elevado, T4 libre disminuido y anticuerpos antiperoxidasa tiroidea negativos. Se suspendió la amiodarona y se inició levotiroxina. Después de dos meses; los niveles de TSH y T4 libre eran normales y la paciente no presentaba molestias. La amiodarona está asociada a diversos efectos adversos que pueden limitar su uso. Entre estos efectos adversos, se describe el hipotiroidismo inducido, que se caracteriza por TSH elevado, T4 libre disminuido y síntomas inespecíficos como fatiga, intolerancia al frío y piel seca. El tratamiento de elección es la levotiroxina.


We report a case of a Wolf Parkinson White syndrome in a 57-yearl-old woman receiving amiodarone (200 mg/ day) who presented with tachycardia, fatigue and somnolence. The physical examination did not reveal goiter, but the osteotendinous reflexes were brisk. Laboratory examinations revealed high TSH level, low T4 free level and negative antiperoxidase antibodies. Amiodarone was stopped and levotiroxine was started. Two months after, TSH and T4 free levels were normal and the patient was asymptomatic. Amiodarone is associated with several side effects that can preclude its indication; one of these side effects is hypothiroidism, characterized by high TSH levels, low T4 free levels and unspecific symptoms such as fatigue, cool intolerance and dry skin. The treatment of choice is levotiroxine.
