Pediatric double positive anti‐glomerular basement membrane antibody and anti‐neutrophil cytoplasmic antibody glomerulonephritis—A case report with review of literature

Abstract

Anti‐glomerular basement membrane (GBM) disease is a rarely described entity in the pediatric population, especially in those less than 3 years old. Even rarer, is double seropositive disease, consisting of anti‐GBM antibody plus anti‐neutrophil cytoplasmic antibodies. Both single and double antibody positive diseases are characterized by rapidly progressive glomerulonephritis, often without pulmonary involvement in the pediatric population. We report the case of a 2‐year‐old child with double seropositive anti‐GBM disease, the youngest in the current literature, along with the role of therapeutic plasma exchange and rituximab in disease treatment.
