Abstract
After an episode of enteritis caused by C. jejuni a 15-year-old boy developed Schönlein-Henoch purpura. Because of continuous proteinuria a renal biopsy was performed. Light microscopy revealed focal proliferative glomerulonephritis. IgA was the dominant immunoglobulin. A causal relationship between enteritis caused by C. jejuni and Schönlein-Henoch purpura complicated with focal proliferative glomerulonephritis is suggested.
