Debilidad muscular con hipokalemia e hipertiroidismo en un adolescente con síndrome de down

Abstract

La hipokalemia aguda es una causa poco frecuente de debilidadmuscular. La parálisis periódica tirotóxica es una complicacióninfrecuente de la tirotoxicosis, en sus diferentes etiologías,en la cual se produce hipokalemia por un flujo masivo depotasio al compartimiento intracelular, que provoca parálisismuscular, que afecta, principalmente, la musculatura proximalde los miembros inferiores. Es importante reconocer estaentidad para instaurar un tratamiento adecuado que incluyael rápido suplemento de potasio y el uso de beta-bloqueantesno selectivos. El tratamiento del hipertiroidismo subyacentey el retorno al estado eutiroideo es imprescindible para laresolución de los episodios de parálisis periódica tirotóxica.Aquí se presenta a un paciente de 13 años de edad con síndromede Down que consultó por debilidad muscular de los miembrosinferiores y trastorno de la marcha, asociada a hipokalemiaaguda, en el que se realizó el diagnóstico de hipertiroidismopor enfermedad de Graves.Palabras clave: parálisis periódicas familiares, hipertiroidismo,metimazol, hipokalemia, síndrome de Down.

Acute hypokalemic paralysis is a rare cause of acute weakness. Thyrotoxic periodic paralysis (TPP) is an unusual complication of hyperthyroidism. It is characterized by sudden onset of hypokalemia condition resulting from a shift of potassium into cells and paralysis that primarily affects the lower extremities. Failure to recognize TPP may lead to improper management. Treatment of TPP includes replacing potassium rapidly, using nonselective beta-blockers and correcting the underlying hyperthyroidism as soon as possible. TPP is curable once euthyroid state is achieved. We describe a 13-year-old male with Down syndrome who presented with acute onset of lower extremity weakness secondary to acute hypokalemia and was found to have new onset Graves’ disease.
