Abstract
A retrospective study of acute glomerulonephritis was performed with respect to type of primary infection and time interval from the onset of the infection to the introduction of antibiotic therapy. 14 out of the 20 patients had had acute tonsillitis, 3 pharyngitis, and 2 skin infections. One patient with no history of focal infection had a simultaneous rheumatic fever. Evidence of streptococcal infection were found in all patients except 4. All patients except 1 received penicillin 6 days or later after the onset of the primary infection or were not treated. The significance of early instituted adequate penicillin treatment of streptococcal infections is discussed.
