Abstract:
Objective To investigate the clinical characteristics and current condition of treatment for systemic lupus erythematosus (SLE) associated pulmonary arterial hypertension (PAH).Methods 10-year inpatients cases were reviewed and followed up.Cases were divided into 2 groups:group A:patients with baseline pulmonary arterial systolic pressure (PASP) lower than 70 mmHg; group B:patients with baseline PASP higher than 70 mm Hg.Pearson's correlation analysis,Chi-square test,Logistic regression,Cox-Mantel and Wilcoxon test were used for statistical analysis.Results There were totally 155 cases with 184 records of admission which accounted for 4.16% among total lupus cases.The main clinical characteristics included Raynaud's phenomenon (47.3%),pericardial effusion (41.9%) and high titer of anti-RNP antibody (55.4%).There were 132 cases enrolled for prognostic statistical analysis.There were 47 cases of death (35.6%) in total,among which 9 cases (19.1%) were in group A and 38 cases (80.9%) were in group B.In group A,there was a positive correlation between PASP and lupus disease activity index score.Single therapy analysis by Chi-square test showed that cyclophosphamide (CTX) (P<0.05) and PAH targeted drugs (P<0.01) were significantly associated with favorable outcome but logistic regressive analysis only confirmed the efficacy of target drugs (P<0.01).PAH target drugs significantly improved the one year survival rate of the severe cases.Conclusion The main clinical characteristics of SLE associated PAH include Raynand's phenomenon,pericardial effusion and positive anti-RNP antibody.The severity of PAH may not be related to lupus disease activity.PAH targeted drugs are effective in SLE-PAH.CTX may be effective in some cases.For severe cases,the combination therapy of CTX and PAH targeted drugs could significantly improve the prognosis.
