Causes chronic nephritis

1 tumors: some blood cancer or colon cancer, lung cancer, can cause chronic nephritis. These tumors may exhibit specific antigen or secretion of certain factors, causing the body produce antibodies to form immune complexes deposited in glomeruli.
2 Primary: This accounted for the majority of patients with chronic nephritis, many environmental factors, mild infections may be the cause.
3 Genetic: Some hereditary nephritis is due to defects in collagen-induced, finally resulting in end stage renal failure, patients may also have other unusual symptoms, such as: deafness or skeletal abnormalities, usually there is a significant family history of end stage renal failure history .
4 drugs: Some drugs, such as painkillers, gold compounds, certain antibiotics, etc., will lead to glomerular lesions.
5 Infection: Many viral or bacterial infections, may be complicated by glomerular lesions. As for the sore throat or skin infection caused by Streptococcus, then the child, can cause acute glomerulonephritis.
6 autoimmune diseases and vasculitis: as lupus erythematosus, also due to the deposition of immune complexes caused by chronic nephritis. And some autoimmune diseases, nephritis itself rarely, such as rheumatoid arthritis, but the use of some drugs, such as non-steroidal anti-inflammatory agent or analgesic drugs gold, it may be complicated by the glomerular lesions. As vasculitis caused by glomerulonephritis, the situation is usually more serious, need active treatment.
