Dr. E.H. Ström, Institute of Pathology, Schönbeinstrasse 40, CH-4003 Basel (Switzerland) Dear Sir, Several studies have demonstrated the presence of IgA nephropathy (IgA-N) in up to 50% of patients with liver cirrhosis [1]. Alcohol-induced cirrhosis has been the most common liver disease associated with IgA-N. However, renal IgA deposits are frequently found in posthepatitic and biliary cirrhos...

IgA nephropathy (IgAN) is the most common primary glomerulonephritis globally, with up to 45% of IgAN patients at risk progressing ESKD. There are currently no approved treatments specifically for nephropathy. The initiating step in pathogenesis excess production galactose-deficient IgA1 (Gd-IgA1) resulting formation pathogenic immune complexes that cause kidney inflammation and damage. A Proli...

Goodpasture's (GP) disease is usually mediated by IgG autoantibodies. We describe a case of IgA-mediated GP, in a patient presenting with isolated rapidly progressive glomerulonephritis. The diagnosis was established on kidney biopsy, since routine enzyme-linked immunosorbent assay (ELISA) targeted at IgG circulating autoantibodies failed to detect the nephritogenic antibodies. Immunofluorescen...

We report two cases of Lyme disease-associated glomerulonephritis. A 57-year-old female presented with rash, volume overload, hypertension and rapidly progressive glomerulonephritis. Biopsy confirmed an immune complex-mediated, membranoproliferative lesion. She was treated successfully with steroids and antibiotics. In a second case, a 40-year-old male, with a previously known microscopic hemat...

IgA nephropathy is the most common glomerulonephritis worldwide and typically has minimal signs for chronicity in histopathology at the time of initial presentation. Pseudotumor cerebri (PTC) is characterized by increased intracranial pressure in the absence of any intracranial lesions, inflammation, or obstruction. PTC has been reported in renal transplant and dialysis patients, but we are una...

The detection of molecular weights of IgA-circulating immune complexes (CIC) in sera is described. Measurement of IgA-, IgG- and IgM-CIC in sera was also performed. Serum samples were obtained from nine patients with IgA nephropathy, nine patients with chronic proliferative glomerulonephritis without IgA deposits (PGN) and 19 healthy adults. Serum samples of these patients were subjected to hig...

Sixty consecutive patients with leprosy were investigated for renal involvement. Clinically overt renal disease was present in 4 patients; 3 presented with a nephrotic state and one patient with progressive renal failure. Urinalysis showed daily protein loss ranging from 0.4 to 8.9 g in 8 patients and microscopic haematuria in 4 cases. Elevated levels of blood urea and creatinine were seen only...

Glomerulonephritis stands third in terms of the etiologies for end-stage kidney disease in the USA. The aim of this study was to look at the patterns of biopsy-proven glomerulonephritis based on data from a single center.Kidney biopsy specimens of all patients above the age of 18 years, over a 10-year period, who had diagnosis of nondiabetic glomerular disease, were selected for the study.The m...
