Glomerulonephritis secondary to non-streptococcal infections

Postinfectious glomerulonephritis (PIGN) is part of a larger group of infection-related glomerulonephritis (IRGN) that harbor the common PIGN and post-streptococcal glomerulonephritis (PSGN) and the less common infectious glomerulonephritis. IRGN is considered to be a cluster of glomerular diseases resulted from immunologic insult secondary to systemic nonrenal infection. Two smaller groups of IRGN have been identified. The first is postinfectious glomerulonephritis (PIGN), which shares a clinical resemblance to PSGN and differs in the causing pathogen (see Table 1). The second is more scarce, with a somewhat different glomerular pathology and is secondary to active bacterial or (more common) viral infection (e.g., hepatitis C virus andHIV). This chapter reviews non-strep PIGN.
