Abstract:
Objective:To analyze the 15-year survival rate, causes of death and prognostic factors of late-onset systemic lupus erythematosus(SLE).Methods:A total of 92 late-onset SLE patients aged >50 years hospitalized in the Rheumatology and Immunology Department of the People's Hospital of Xinjiang Autonomous Region from January 2006 to December 2016 were retrospectively collected.Clinical and serological data of the patients were analyzed and the diagnosis met the SLE classification criteria as revised by the American Society of Rheumatology in 1997.Survival rate, the cause of death, and the associated prognostic factors were analyzed.Outpatient or telephone follow-up was performed.Results:Of the 92 study patients, 8 were lost to follow-up(8 / 92, 8.7%)and 84 were able to follow up(84 / 92, 91.3%). Of the 84 able to follow up, 64 cases(64 / 84, 76.2%)survived, and 20 cases(20 / 84, 23.8%)died.Median survival time was 108 months.The 5-, 10-, and15-year survival rates were 86.0%, 77.9%and 59.6 %, respectively.Infection(55.0%)and multiple organ failure(15.0%)were the major cause of death in patients with late-onset SLE.Univariate analysis of the outcomes of patients with late-onset SLE showed that the age of onset( HR=1.113, P=0.001), hematology involvement( HR=3.610, P=0.023), and complicaed cardiovascular disease( HR=3.128, P=0.011)had a significant impact on the prognosis. Conclusions:The late-onset SLE has low survival rate and bad prognosis.Infection prevention and control of organ damage and focus on merging cardiovascular disease are critical to improve survival of late-onset SLE patients.
