Background: Mesangioproliferative glomerulonephritis is the most common type of chronic glomerulonephritis (CGN). However, the clinical characteristics and prognosis are not fully understood in patients without Immunoglobulin A (IgA) deposition. To explore the clinical and pathological characteristics of patients with mesangioproliferative glomerulonephritis without IgA deposition (N-IgAN), we ...

Familial Mediterranean fever (FMF) is an inherited auto-inflammatory disorder. Secondary AA amyloidosis is the most devastating complication of FMF. Nonamyloid renal involvements have also been reported in association with FMF, including vasculitis, focal and diffuse glomerulonephritis, and IgA nephropathy. We describe a patient with FMF and E148Q mutation who presented with massive proteinuria...

The therapeutic effects of saccharolytic and proteolytic enzymes were investigated in models of IgA nephropathy. Mesangial glomerulonephritis was induced in mice by intravenous injection of preformed soluble immune complexes of dextran sulfate and either IgA (J 558) or IgM (MOPC 104 E) antidextran MAb (passive model) or by immunization with DEAE dextran (active model). In the passive model, onl...

BACKGROUND Cadmium is a metal used in the zinc, copper and steel industries, and in the manufacture of electric batteries and solar cells. Acute cadmium poisoning is characterized by irritation of the respiratory tract, while in chronic poisoning the main target organ is the renal tubule. AIMS We report a patient with chronic work overexposure to cadmium, who presented a IgA mesangial glomeru...

Serum immunoglobulin A (IgA) was markedly increased in 80% of 50 patients with acute rheumatic fever in Trinidad in contrast to 20% of 63 patients with acute glomerulonephritis, whereas serum IgG was increased in nearly all of both groups. Since total antibody to M-associated protein (MAP) (assessed by complement fixation) is the only antibody as yet consistently found to be of higher titer in ...

Structural aberrations of O-linked glycans present in the IgA1 hinge region are associated with IgA nephropathy, but their contribution to its pathogenesis remains incompletely understood. In this study, mice implanted with hybridoma secreting 6-19 IgA anti-IgG2a rheumatoid factor, but not 46-42 IgA rheumatoid factor bearing the same IgA allotype, developed mesangial deposits consisting of IgA,...
