Childhood glomerulonephritis associated with varicella and streptococcal infection

Varicella is a usually benign disease of childhood and its complications are uncommon in immunocompetent children. In recent years we have witnessed the increasing virulence of group A beta-haemolytic streptococci (GABHS). In particular, in 1993, 50% of new cases of invasive GABHS disease were associated with varicella infection and all were suppurative complications. Because also a non suppurative complication of varicella as glomerulonephritis associated with GABHS infection, has been published in only one case, we feel that it could be of interest to describe this condition in two other cases we have observed.
