Postinfectious acute glomerulonephritis associated to influenza B virus and enterovirus

Acute post-infectious glomerulonephritis (APIGN) is an inflammatory lesion with main involvement of the glomerulus triggered by an extrarenal infection. Its pathogenesis is immune, triggered by a wide variety of germs: bacteria, viruses and fungi. The most common cause is poststreptococcal glomerulonephritis (PSAGN). The case that we present was associated to influenza B and enterovirus, etiological agents of infrequent presentation, with clinical manifestations similar to post-streptococcal glomerulonephritis. We conclude that, when faced with a nephritic syndrome clinic, the viral history should be taken into account to make an early diagnosis.
