The study of the activation of C3, C5, and C7 associated with the conversion of C3 in the serum of a 9-yr old girl after incubation at 0 degrees C for 6-8 h without utilization of C1, C4, and C2 is described. The patient has upper respiratory infections associated with recurrent gross hematuria, focal glomerulonephritis, and transient renal insufficiency. Histological lesions demonstrated the p...

IgA nephropathy (IgAN) is the most common pattern of primary glomerulonephritis seen in the Western world. In the majority of cases the cause remains unknown. Cases of familial IgAN and secondary IgAN have been reported and these have provided insights into underlying genetic and environmental triggers for this common glomerular disease. Secondary IgAN is seen most commonly in patients with liv...

BACKGROUND IgA nephropathy, a prevalent disease in Asia, is considered the main cause of end stage renal disease among primary glomerular disease. OBJECTIVE To determine the frequency of different clinical, histopathological and immunofluorescent characteristics of IgA nephropathy. METHODS Renal biopsies of 376 patients were received for immunofluorescent and for histopathological studies. ...

IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. If left untreated, about 40% of patients progress to end-stage renal disease over 20 years. Currently, there no established disease-specific treatment. Toll-like receptor (TLR)9 and TLR7 have been reported be involved in synthesis galactose-deficient IgA1 (Gd-IgA1), which plays a vital role pathogenesis IgAN. Furthe...

Anti-glomerular basement membrane disease is characterized by autoimmunity to antigenic sites on type IV collagen of the glomerular basement membrane. The majority of patients present with rapidly progressive glomerulonephritis and alveolar hemorrhage. The occurrence of antiglomerular basement membrane disease and other types of glomerulonephritis, such as membranous nephropathy, IgA nephropath...

IgA nephropathy is the most common primary glomerulonephritis worldwide and carries a substantial risk of kidney failure. New agency-approved therapies, either specifically for or chronic disease in general, hold out hope mitigating renal deterioration patients with nephropathy. The latest addition to this therapeutic armamentarium targets endothelin-A receptor (ETAR). Activation ETAR on multip...

BACKGROUND IgA nephropathy (IgAN) is the most common glomerulonephritis in the world, affecting close to a million people. Circulating galactose-deficient IgA (gd-IgA), present in patients with IgAN, form immune complex deposits in the glomerular mesangium causing local proliferation and matrix expansion. Intriguing though, individuals having gd-IgA deposits in the kidneys do not necessarily ha...
