چکیده

A light, electron and immunofluorescence microscopy study was performed on 102 consecutive patients on whom suitable percutaneous renal biopsies were obtained. In this selected group of patients primary IgA glomerulonephritis was diagnosed in 6 (5.9%) cases. On light microscopy the glomerular lesions were predominantly focal (WHO class III) and diffuse mesangial proliferative glomerulonephritis (Class IV). The mesangial deposits showed high association with IgM deposits and presence of early complement components (C1q, C4) indicative of both classical and alternative pathways of C3 activation in our patients. The high incidence of nephrotic syndrome with microhaematuria (5 cases) is due to patient selection when compared to other studies. This study shows the existence of IgA nephropathy in Pakistan and larger number of cases need to be investigated to determine the true prevalence of this disease and its clinical manifestations and importance in Pakistan.

IgA nephropathy: an update on pathogenesis and classification.

IgA nephropathy is a primary glomerulopathy characterized by deposition of IgA containing immune deposits in the kidney. Its diagnosis is based on histopathologic and immunoflourescence studies on renal biopsy. The disorder is poorly understood. This review is focused on updates regarding its pathogenesis and discussion on a new proposed histopathological classification of IgA nephropathy.

شیوع نفروپاتی IgA در بیماران مبتلا به گلومرولونفریت اولیه

During a 14-month period (Dec. 1990-Jan. 1992) , renal biopsies were performed on 105 patients with suspected glomerular disease. All specimens were processed for light microscopy (L.M) and immunoflourescence. Work-up revealed 21 patients to suffer a systemic glomerular disease and glomerular disease was found to be primery in 85 cases. Predominant IgG deposition was noted in 71 cases with prim...
