Abstract: | We investigated the causes of death and analyzed the prognostic factors in Korean systemic lupus erythematosus (SLE) patients. We evaluated 1010 patients with SLE who visited Seoul Saint Mary's Hospital from 1997-2007. Changing patterns in the causes of death were analyzed. Survival rate was calculated by the Kaplan-Meier method and the log-rank test. The risk factors for death were analyzed by multivariate logistic regression analysis. The 5-year survival rate was 97.8%. Over the period of the study, 59 deaths were observed. Among 44 patients who died in our hospital, the most common cause of death was infection (37.3%), with SLE-related death as the next most frequent cause (22.0%). In comparison with earlier data, the proportion of SLE-related deaths has fallen and the proportion of infections has risen. SLE-related death was the most frequent cause of early death, while infection was the most common cause of death in the overall population. In univariate analysis, damage related to SLE, cumulative glucocorticoid dose, mean glucocorticoid dose for 1?month before death, intravenous methylprednisolone therapy and cyclophosphamide treatment were associated with death (p?0.001 each). The late onset of SLE and renal involvement were predictive factors of poor outcome (p = 0.03 and p?0.001). In multivariate analysis, the risk factors for death were irreversible damage related to SLE, cyclophosphamide therapy and mean glucocorticoid dose for 1?month before death. The most common cause of death in Korean SLE patients was infection. The judicious use of immunosuppressive agents may be important to decrease infection and to improve survival in SLE patients. |
