Document Details : Title: Membranous glomerulopathy in a patient with selective IgA deficiency: is there a link? Author(s): VANACKER A, VAN DORPE J, MAES B Journal: Acta Clinica Belgica Volume: 66 Issue: 3 Date: 2011 Pages: 228-230 DOI: 10.2143/ACB.66.3.1002951 Abstract : We report a 42-year-old woman, who presented with proteinuria (3,85 g/day) and malleolar oedema. She had a medical history of Graves’ disease, recurrent upper respiratory tract infections, episodes of Raynaud phenomenon and dysphagia. Biochemistry showed a selective IgA deficiency (SIgAD). Percutaneous renal needle biopsy showed diffuse global thickening of the glomerular basement membranes on light microscopy and granular deposits of IgG and C3 along the glomerular basement membranes on immunofluorescence. The pathological diagnosis was membranous glomerulopathy stage II. A treatment with dietary salt restriction and an angiotensin-converting enzyme inhibitor was initiated, resulting in a reduction of proteinuria. Despite the fact that selective IgA deficiency is associated with various autoimmune disorders, the association with glomerular disease is rather rare and the pathogenesis is not fully understood. |
