Legionella pneumophyla is the agent responsible of Legionnaire's disease. It appears as a severe pneumonia and often requires admission in Intensive Care Unit. In literature, renal failure is reported to occur in 15 percent of Legionnaire disease and this event induce a mortality over 50% of these cases. The authors describe a case of Legionnaire's pneumonia with respiratory failure, rhabdomyolysis and acute renal failure. Patient was a female, 61 yrs old, admitted to our hospital because of fever (38 degrees-38.5 degrees C), severe respiratory failure (pH = 7.49, PaCO2 = 23.1 mmHg, PaO2 = 56.7 mmHg), oliguria (< 200 ml/24 h); chest x-rays and computed tomography (TC) showed a pneumonia at right lower lobe. Among other things, in blood analysis was noted the following values: BUN = 47 mg/dl, creatinine = 2.1 mg/dl, Na+ = 133 mmol/L, Cl- = 97 mmol/L, Ca+ = 7.2 mg/dl, K+ = 5.8 mmol/L, AST = 213 U/L, ALT = 45 U/L, LDH = 1817 U/L, CPK = 16738 U/L, CPK-MB = 229 U/L, myoglobin > 4300 ng/ml., leucocyte count = 17,500/mmc (N = 92%, L = 3%, M = 5%), positive anti Legionella IgG and IgM (IgG > 1:64, IgM > 1:96), evidence of Legionella soluble antigen in the urine analysis. Therapy with clarytromicyne (500 mg b.i.d i.v.) and rifampicin (600 mg/die i.v.) was begun; computed tomography showed after six days an improvement of pulmonary lesion but, in the following days, health status and blood analysis got worse. Patient went on antibiotics and underwent haemotherapy (Hb: 8 gr/dl), haemodialysis because of acute renal failure but healthy status worse furthermore and she died on 18th days after admission. This case point out rhabdomyolysis with acute renal failure is suggestive for Legionnaire's disease and is associated with high rate of mortality.
