There is no fixed answer as to how long a person can live with lupus erythematosus nephritis is related to the patient’s physical condition and the severity of the disease. If the treatment is timely, long-term survival is possible. At present, the five-year survival rate of patients with lupus nephritis in China has exceeded 90%, and the ten-year survival rate has exceeded 80%. If the symptoms are serious and the treatment is not timely, then it can also be life-threatening in the short term, with only a few months or years of survival. Therefore, it is recommended that patients with lupus erythematosus nephritis be treated early and promptly. Patients with mild symptoms can survive for a long time with active treatment, otherwise the condition is critical and can affect life expectancy and even lead to sudden death. Specific diagnosis and treatment need to follow the doctor’s advice.
