Fibrillary glomerulonephritis and renal failure in a child with systemic lupus erythematosus.
Fibrillary glomerulonephritis (FGN) is a rare immune-mediated glomerulopathy characterized by randomly arranged immunoglobulin (Ig) deposits on electron microscopy. Only seven pediatric cases have been reported, and the incidence in adults is about 1.5%. A 12-year-old boy presented with systemic lupus erythematosus (SLE) with World Health Organization Class IV lupus nephritis. A repeat biopsy carried out due to a poor response to standard immunosuppressive therapy and worsening renal functions revealed diffuse proliferative glomerulonephritis with fibrillary deposits. Despite aggressive immunosuppression with plasmapheresis and rituximab, the patient developed end stage renal disease. This is an atypical pediatric case characterized by SLE-associated FGN and a poor prognosis.
