Abstract:
ObjectiveTo investigate the changes of high resolution computerized tomography (HRCT) of chest and quality of life and the main correlated factors of HRCT for interstitial lung disease(ILD) in patients with rheumatoid arthritis(RA).MethodsTwenty-six initial treatment patients with RA-ILD were enrolled.The following parameters were noted at baseline,12 and24 weeks for each patient:clinical features,HRCT,quality of life.ANOVA was used for repeated measurement data and stepwise multiple regression analysis were used to analyze the relativity between HRCT and other parameters.ResultsTwentysix patients were included.Twelve male(46％) patients were followed up for 24 weeks and pulmonary infection occurred in 11 patients,so the frequency rate was 42％.After being treated with prednisone and cyclophosphamide for 24 weeks,the HRCT scores were lower than before [(8+6) vs(12±5),respectively] and 16 patients' condition were improved,6 were in stable and 4 had deteriorated disease.For quality of life,the impact scores,symptom scores,activity scores,and total scores of St.George's respiratory questionnaire (SGRQ) were significantly decreased(F=3.783,6.362,4.217,4.426,P＜0.05) and all domains of the short form-36 health survey questionnaire(SF-36) had significant improvement after treatment.Stepwise multiple regression analysis showed that the impact scores(P=0.000) and symptom scores(P=0.001) of SGRQ,vitality (P=0.012) of questionnaire,globulin (P=0.027) in prior treatment and symptom scores (P--0.001 ) of SGRQ,course of disease (P=0.002),MRC score (P=0.011),vitality (P=0.036) of SF-36 questionnaire in post-treatment were the main correlated factors with HRCT features.ConclusionMale RA patients are prone to develop ILD and RA-ILD is susceptible to pulmonary infection.After early treatment,HRCT and quality of life in most patients can be improved.Respiratory symptoms,severity of dyspnea,globulin level,course of disease and vitality of patients are significantly correlated with HRCT.
