Abstract:
Objective To study the clinical characteristics and analyze the correlative risk factors of interstitial pneumonia in systemic lupus erythematosus (SLE-IP).Methods 80 SLE patients in department of rheumatology of Nanfang hospital form January 2013 to January 2016 were retrospectively analyzed.SLE patients with interstitial pneumonia (n=40) were divided into case group.40 cases of SLE with interstitial pneumonia were selected and matched with age and sex.Patients with mild SLE without interstitial pneumonia were treated as controls.The clinical manifestations,routine examination,biochemical examination and immunological examination were performed to compare the risk factors of SLE-related interstitial pneumonia.Results In this study,non-specific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP) were common in SLE-IP patients.the ground-glass opacities were more common in NSIP type,while Grid shadows and honeycomb shadows were more common in UIP type.The dry cough,chest tightness / shortness of breath,Raynaud's phenomenon,wet rales,triglyceride increased,anti-Sm antibody positive rate,anti-U1-nRNP positive rate between two groups were statistically significant (P＜0.05).Logistic regression analysis showed that the risk factors of SLE-IP were dry cough,chest tightness / shortness of breath,Raynaud's phenomenon,wet rales,triglyceride increased,anti-Sm antibody positive and anti-U1-nRNP positive.Conclusion The presence of dry cough,chest tightness / shortness of breath,Raynaud's phenomenon,wet rales,triglyceride increased,anti-Sm antibody positive and anti-U1-nRNP positive all suggest the probability of interstitial pneumonia in SLE patients.HRCT plays an important role in the diagnosis of interstitial pneumonia in lupus,which is valuable to improve the prognosis.
