Abstract
Background: C3 glomerulopathy is a rare entity, secondary to a dysregulation of complement alternative pathway
Purpose: The purpose of this article is to report the case of a teenager who presented acute glomerulonephritis, initially suspecting membranoproliferative glomerulonephritis and/or poststreptococcal glomerulopathy, with significant compromise of glomerular filtration, low C3 levels, severe arterial hypertension and proteinuria with renal biopsy compatible with C3 glomerulopathy, with a membranoproliferative pattern also suggestive of thrombotic microangiopathy
Case presentation: We report the case of a teenager who was diagnosed with C3 glomerulopathy and thrombotic microangiopathy, without response to initial 8-week management with steroids.
Discussion and conclusions: This is a rare and recently described entity, with evidence of significant compromise in renal function and some patients, progression to renal failure. In the case of this teenager, he received anticomplement therapy with eculizumab with resolution of the diasease, in the follow-up, was achieved without evidence of complications or side effects documented to date.
