Antibodies also attack the collagen of the air sacs of the lung (alveoli) resulting in bleeding of the lung (pulmonary hemorrhage). Symptoms may include general body discomfort or pain, bleeding from the nose and/or blood in the urine, respiratory problems, anemia, chest pain, and kidney failure. Anti-GBM disease is thought to result from an environmental insult (smoking, infections, exposure to certain drugs) in a person with genetic susceptibility, such as a specific human leukocyte antigen (HLA) type. Diagnosis is confirmed with the presence of anti-GBM antibody in the blood or in the kidney. The treatment of choice is plasmapheresis in conjunction with prednisone and cyclophosphamide.
