[Acute rhabdomyolysis. A study of 44 cases].

Fourty four patients suffering non traumatic rhabdomyolysis (RM) are studied. The most frequently encountered etiologies were neurologic abnormalities in 26 patients, followed by infections in 7 patients and metabolic abnormalities in four cases. Eleven patients (25%) presented several associated factors. The clinical manifestations of RM were not very significant, with only 18% of patients presenting muscle pain, 38.6% proteinuria and 36.4% hematuria. A significant increase in K, CPK, LDH, and ASAT values was observed after the RM episode (p less than 0.05). Those patients with an infectious RM were older (p less than 0.05) and presented higher urea (p less than 0.01) and creatinine (p less than 0.05) values. Only two patients presented renal failure. One patient with septic shock died. RM is a relatively common condition, often secondary to multiple systemic processes, which can go unnoticed due to the underlying disease.
