The relationship between nephritogenic strains of group A beta-hemolytic streptococci (GABS) and acute poststreptococcal glomerulonephritis (APSGN) is well established. Recent studies have cast some doubts on the importance of the M-antigen which is widely used in classifying the nephritogenic strains of GABS. The renal injury occurs as a result of an immune-mediated process which involves the complement system. This leads to deposition of circulating immune complexes and/or their in-situ formation in the kidney resulting in renal damage. Newer antigenic fractions have been identified in GABS, which include; endostreptocin (ESS), nephritis strain associated protein (NSAP), and pre-absorbing antigen (Pa-Ag). These developments have allowed a better insight into the pathogenesis of APSGN. |
