Serum creatine phosphokinase in leptospirosis.
Serum creatine phosphokinase (CPK) and serum glutamic oxaloacetic and pyruvic transaminase (SGOT, SGPT) levels were determined in 61 patients with leptospirosis and 16 with viral hepatitis during the acute phase of illness. The CPK value was elevated in 29 leptospirosis patients and normal in all 16 hepatitis patients. Conversely, mean SGOT and SGPT levels were lower in leptospirosis patients. The CPK determination is a simple test that may provide diagnostic information in a jaundiced patient, particularly when characteristic manifestations of leptospirosis are absent. The pattern of greatly elevated CPK levels with only modest elevations in transaminase values in an acutely jaundiced patient should strongly suggest a diagnosis of leptospirosis.
