How long a patient with lupus erythematosus nephropathy can live depends on the specific condition. Most patients, as long as they have not reached renal failure, or have not reached the uremic phase, can control the disease through reasonable and effective treatment, and can also delay the survival period. The current 20-year survival rate has been significantly improved from before, and can reach about 70%. Therefore, patients must have confidence to build up the confidence to overcome the disease and also the determination to treat it for a long time. If renal impairment progresses progressively, it is possible to reach the uremic stage and become life-threatening, and often renal replacement therapy will eventually be required. But eventually, a state of multi-system and systemic failure will also occur, eventually leading to death. Therefore early diagnosis and rational treatment at an early stage is crucial.
