Acidóse tubular renal distal manifestando-se com rabdomiólise

Distail renal tubular acidosis manifesting with rhabdomyolysis

Resumos

A hipocalemia severa é causa incomum de rabdomiólise. Descreve-se o caso de urna paciente de 28 anos com acidóse tubular renal distal, que desenvolveu hipocalemia severa com consequente rabdomiólise. O estudo histológico do músculo evidenciou áreas focais de necrose muscular predominando em fibras do tipo II, com discreta reação macrofágica. A melhora clínica e laboratorial apresentada pela paciente ocorreu após a normalização do potássio sérico, tendo sido fundamental, neste caso, a correção da acidóse metabólica.

Severe hypokalemia is an uncommon cause of rhabdomyolysis. We describe a patient, 28-year-old woman, with distal renal tubular acidosis (DRTA) who developed severe hypokalemia and rhabdomyolysis. Muscle biopsy shows focal muscular necrosis mainly in type II muscle fibers and mild macrophagic reaction. After correcting the acidosis with oral administration of alkalinizing salts, clinical and laboratory improvement was seen. This clearly establish a causal realtionship between the positive acid balance, hypokalemia and the muscular manifestation in DRTA.
