[Acute renal failure in hantavirus infections].
BACKGROUND
The acute renal failure remains a diagnostic challenge for the clinician.


METHODS
Between 1991 and 1996, acute renal failure caused by hantavirus infection was diagnosed in 4 previously healthy male patients. Main symptoms consisted of fever, headache, arthralgia, lumbar and abdominal pain as well as a decline in diuresis. The ultrasonography showed a slight splenomegaly in 2 patients. The clinical chemistry showed elevated serum creatinine from 2.2 mg/dl to 6.7 mg/dl and thrombocytopenia from 4000 to 150,000/microliter. The examination of the urine showed slight proteinuria and microhematuria. The kidney biopsy of 1 patient showed a reversible damage of the tubuli. The pathologic findings normalized within 3 weeks in 3 patients without need for dialysis. One patient developed a severe clinical course with acute renal failure and pulmonary edema requiring dialysis. In all patients, the renal function improved.
