Acidóse tubular renal distal manifestando-se com rabdomiólise

Abstract

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 relationship between the positive acid balance, hypokalemia and the muscular manifestation in DRTA.
