ACUTE INTERSTITIAL NEPHRITIS ASSOCIATED WITH IGA NEPHROPATHY IN CHILDREN

IgA nephropathy (IgAN) is a relatively common glomerulopathy in childr en and adolescents. The etiology of this disease is uncertain. We prev iously reported a child with IgAN who developed acute interstitial nep hritis. We now describe three pediatric patients, including the index case, who had IgAN and who developed concomitant acute interstitial ne phritis in association with renal functional impairment. We suggest th at this histopathological lesion be considered in any child with IgAN and unexpectedly severe kidney dysfunction.
