title: Death-related factors of systemic lupus erythematosus patients associated with the course of disease in Chinese populations: multicenter and retrospective study of 1,958 inpatients.
abstract: Despite the improved survival rate among systemic lupus erythematosus (SLE) patients, there are many factors associated with the mortality of SLE. In the current study, death-related factors of patients associated with course of disease were surveyed. Retrospective study was used. Mortalities among these three groups (group A, B and C, the course of disease was ≤ 5 years, 5-10 years and > 10 years, respectively) were calculated and compared. Various factors related to mortality were analyzed. Male SLE patients died relatively more than female patients. The total mortality was 8.5 %. The mortalities were significant difference in group A, B and C which were 9.4, 4.8 and 8.9 %, respectively. The mortalities of group A and group C were significantly higher than that of group B, but there was no significant difference between mortalities of group A and group C. The most common death-related factor was infection, followed by involved disorders in renal, brain, multisystem, heart, etc. The mortalities resulted from neuropsychiatric systemic lupus erythematosus (NPSLE), pulmonary infection, involved digestive system and hematological system were significantly different between three groups. There was no difference between mortalities of group A and group C associated with pulmonary infection and NPSLE. Patients in group C died more than in group A from involved renal, heart, multisystem, etc, while group A had more patients than group C who died of pulmonary infection, involved hematological system. In conclusion, Male SLE patients have worse outcome than female patients. Infection and active SLE are not only contributors to the death of early stage patients, but also to that of later stage patients.
