Rapid development of diffuse crescents in post-streptococcal glomerulonephritis.
A 14-year-old boy presented with 3 days of hematuria and oliguria following impetigo. Renal biopsy showed diffuse endocapillary proliferative glomerulonephritis with subendothelial electron dense deposits but no crescents. Due to recrudescence of clinical abnormalities after initial improvement, the patient was re-biopsied 10 days later. This biopsy showed circumferential crescents in 83% of the glomeruli. Treatment with intensive plasma exchange, prednisolone, cyclophosphamide and dipyridamole was accompanied by prompt improvement in renal function. The need to carefully monitor the course in patients with acute post-streptococcal glomerulonephritis is emphasized.
