Subacute Sclerosing Panencephalitis Associated Glomerulopathy

Subacute sclerosing panencephalitis (SSPE) is a progressive neurologic disease associated with chronic measles infection. We have assessed renal function parameters and renal biopsy details in 14 patients with SSPE. All had normal renal function. However, 9 had microscopic hematuria. 9 patients had focal segmental mesangial proliferation and 5 had capillary wall thickening with deposits visible by light microscopy. 13 patients had glomerular C3 deposition and 4 had IgG deposits. SSPE is a disease caused by chronic viral infection, in which nephritogenic complex formation may occur.
