[Current clinical aspects of leptospirosis]

Leptospirosis is still endemic in the Po valley. It has an extremely protean clinical picture. In a series of 79 cases diagnosed at Pavia in the period 1970-79 hepatonephritic forms were the most common (29.1%), followed by febrile or pseudo-influenza forms (25.3%), hepatitis (20.2%), nephritis (17.8%), and meningitis (7.6%). Febrile hepatonephritis was always accompanied by the most severe pictures. Timely antibiotic management with penicillin or ampicillin, and above all the early use of peritoneal dialysis (carried in 10 subjects) enable a final cure to be obtained even in these cases. The only death in that series did not appear to be ascribable to the disease itself.
