Candida endocrinopathy syndrome with membranoproliferative glomerulonephritis: demonstration of glomerular candida...

A boy who had the Candida endocrinopathy syndrome, consisting of mucocutaneous candidiasis, hypoparathyroidism and hypoadrenocorticism, also had hypocomplementemic membranoproliferative glomerulonephritis. A renal biopsy at age 16 showed lobular glomerulonephritis with chronic interstitial inflammation. Glomerular and focal tubular deposition of IgG and C3, but not C4, were seen by immunofluorescence microscopy. Electron microscopy revealed dense intramembranous deposits in glomerular, tubular and Bowman's capsul basement membranes. C. albicans antigenic material was detected in the glomeruli by immunofluorescence microscopy using an FITC-labelled rabbit antiserum to the patient's organism. These fidings suggest that chronic C. albicans infection led to an immune complex form of nephritis. Clinical and laboratory evidence of resolution of his nephritis and return to normal serum levels of C3 followed prolonged antifungal therapy.
