Lupus nephritis is more serious and lupus nephritis is caused by a disease called systemic lupus erythematosus. SLE is an autoimmune disease that produces very many antibodies, which are not used to kill bacteria, but to attack themselves, and when they attack the kidneys it is called lupus nephritis. In addition to attacking the kidneys, it also attacks the lungs, the digestive tract, the nervous system, and so on. If the patient’s disease progresses more rapidly or is not very sensitive to the treatment drugs, the patient will die of multiple organ failure in a short period of time, so this disease is very serious. This disease is usually treated with hormones combined with immunosuppressive drugs, which suppress the overwhelming immune response in the body and prevent the attack on the organs of the body. In case of fulminant lupus nephritis, blood purification treatment can also be considered, mainly plasma exchange, to remove the harmful antibodies from the body.
