Clinicopathological features and prognosis of Chinese patients with acute post-streptococcal glomerulonephritis

Nephrology (Carlton). 2010 Sep;15(6):625-31. doi: 10.1111/j.1440-1797.2010.01352.x.


Aim: To investigate clinicopathological and prognostic differences between adults and children with acute post-streptococcal glomerulonephritis (APSGN).

Methods: A retrospective case series of 112 patients with APSGN was undertaken. Patients were divided into two groups according to age: adults aged more than 17 years and children aged less than 15 years.

Results: The incidence of APSGN, especially in adults, has decreased in the past three decades. Children have had a higher incidence of macroscopic haematuria than adults (58.3% vs 32.7%, P < 0.05). Laboratory test showed that red blood cell count of urine sediment in children was more significant. On light microscopy, adults had more global glomerulosclerosis, tubular basement membrane thickening, tubular atrophy and interstitial fibrosis, while children had more glomerular infiltrating neutrophils and monocytes and cellular casts. Immunofluorescence microscopy showed that classical staining was seen more in children. The short-term prognoses were good in both children and adults. But the recovery rate of proteinuria in children was faster than that in adults.

Conclusion: Adults with APSGN had similar clinical features as children except that children had more significant haematuria. On pathology, adults had more outstanding chronic changes by light microscopy and more untypical staining by immunofluorescence.
