Introduction
Anti- glomerular basement membrane (GBM) disease is an uncommon autoimmune disorder that is characterized by rapidly progressive glomerulonephritis (GN) caused by autoantibodies against the α3-chain of type IV collagen in the GBM. Commom variable immunodeficiency (CVID) is a primary immunodeficiency manifested by hypogammaglobulinemia, inability to make functional antibody, and recurrent infections. We report an interesting association of anti-GBM disease with CVID.
Case Description
A 15-year-old Caucasian female with prior normal renal function presented with 2 weeks of nephrotic proteinuria, oliguria, AKI, and was found to have serum anti-GBM antibody. She had been diagnosed with CVID and West Nile meningoencephalitis at 3 and 12 yrs of age respectively. Her renal biopsy showed crescentic GN with at least 50% global glomerulosclerosis and immunofluorescence showed linear staining for IgG along the glomerular capillary wall. There was no clinical or radiological evidence of pulmonary hemorrhage. She was treated with pulse IV steroids, Cyclophosphamide, Rituximab and several sessions of plasmapheresis. Her serum anti-GBM antibody level decreased from 194 U/mL at presentation to 0 U/mL post therapy. However, she progressed to ESRD within weeks and required dialysis. Her clinical course was complicated by hypertensive encephalopathy, CMV meningoencephalitis, CMV viremia, status epilepticus, and she passed away a few months later from lower respiratory infection related complications.
Discussion
Anti-GBM disease is a rare autoimmune condition, which has not been reported in association with a primary immunodeficiency syndrome. ESRD secondary to anti-GBM disease in a patient with CVID is an interesting association and supports role of immune dysregulation in systemic autoimmune disease.
