What is Anti-GBM/Anti-TBM nephritis
Anti-GBM/Anti-TBM nephritis: Anti–glomerular basement membrane (anti-GBM) antibody disease is a rare autoimmune disorder caused by autoantibodies that attack the walls of small blood vessels (capillaries) in the kidney. Anti-GBM disease that only affects the kidneys is called anti-GBM glomerulonephritis. This is a form of inflammation (-itis), which is injury to tissue caused by white blood cells (leukocytes). Glomerulonephritis due to Anti-GBM antibody disease is rare. It occurs in less than 1 case per million persons. It affects mostly young, white men aged 15-35. After age 50, women are more likely to be affected. The sexes overall are affected approximately at a male-female ratio of 3:2. It is seen very rarely in children. Some evidence suggests that genetics may play an important role in this disease. 60-70% of patients have both lung and kidney involvement. This is called Goodpasture’s Syndrome. 20-40% have only kidney involvement, which is called “renal limited” anti-GBM disease. Symptoms may include: chills and fever, nausea and vomiting, weight loss, chest pain, bleeding may cause anemia, respiratory failure, and kidney failure. Treatment of anti-GBM disease is focused on removing the anti-GBM antibody from the blood.
