Legionnaire's disease complicated by acute renal failure due to rhabdomyolosis: a case report

The infectious origin of non-traumatic rhabdomyolysis is rare (5% of cases). An elevated muscle enzyme level is often reported in the legionnaire's disease. We report the case of a 39-year-old male, with no previous medical history, admitted for renal failure (creatininemia=977 micromol/l) secondary to rhabdomyolysis and a twelve-day history of infectious syndrome with pneumonia in the left base. Legionella pneumophila was considered responsible for these symptoms because of a positive serology. The other microbial assessments were negative. After rehydration and three weeks of antibiotics, the outcome was favorable: the renal failure resolved completely and the muscle enzyme level returned to normal.
