Abstract:
Objective To explore the relationship between the impairment of hematological system and disease activity,immunological parameters,and the prognosis of systemic lupus erythematosus (SLE).Methods The clinical and laboratory data of in-patients with SLE in Jiangsu Province were investigated and all patients were hospitalized between 1999-2009.The impairment of hematological system was assessed and the relationship between hematological system damage and disease activity,immunological parameters,mortality rate of patients with SLE were analyzed.Statistic method used was X2 test.Results One thousand nine hundred and fifty eight cases of SLE were included in the study,in which,1836 were female and 122 were male.One thousand five hundred and forty nine (79.1%) patients complicated with hematological system damage,62.3% were anemia,45.5% with leucopenia and 29.4% with thrombocytopenia.There were significant differences in hematological system damage rate among patients with mild activity group,moderate activity group,severe activity group and almost no activity group,compared respectively with almost no activity group.The P values were P=0.01 and P＜0.01 respectively.The incidence of hematological system damage in elevated ESR,low complement C3 level,anti-dsDNA antibody group was higher than that in patients who had normal ESR,complement C3 level and anti-dsDNA group.(P＜0.01).During follow-up,166 patients died,of which the mortality rate(91.6%) in patients had hematological system damage,was obviously higher than those without hematological damage(8.4%)(P＜0.01 ).Among the 166 deceased patients,38.6% died of severe infection,22.9% died ofrenal failure,15.1% died ofnervous system damage,10.2% died of cadiovascular damage and 13.3% died from other causes.Conclusion Hematological system is one of the most commonly involved system in patients with SLE,of which anemia is the most common,and the incidence of leukopenia follows.The impairment of hematological system is closely related to lupus activity.Patients with abnormal immune parameters tend to have secondary hematological system damage.Severe infection is the main cause of death in patients with lupus,followed by nervous system damage and kidney damage.The mortality rate in patients with lupus that complicated hematological system damage is higher than patients who have no hematological system damage.
