Abstract:
Objective To evaluate the clinical and image characteristics of rheumatoid arthritis (RA) patients accompanied with bronchiectasis (BR).Methods By retrospectively analyzing 67 patients admitted to our department,we divided RA patients into RA-BR group and non-BR group,according to the presence of BR or not.For those with interstitial lung disease (ILD),the ILD lesions were classified by inflammatory,fibrosis and mixed pattern.The clinical and image characteristics,as well as the correlation between BR patients with clinical/other lung changes were analyzed.Independent sample t test was used to compare the difference between the two groups if the data was normally distributed and those data that were not distributed normally were analyzed by Mann-Whitney U-test.Spearman correlation analysis was used for variables related analysis.Logistic regression analysis was used to identify independent risk factors for the presence of respiratory symptoms.Results Twenty-nine patients (43％) showed BR in CT scan.There was no statistically significant difference between BR and uon-BR group in age,gender,disease course of RA,smoking history and rheumatoid serology;respiratory symptom was presented in 6 pts in both groups;bronchiectasis involved unilaterallung in 10 patients (34％) and bilaterally in 19 (66％),26 patients (90％) were found to have bronchiectasis in their lower lobe.ILD was presented in 12 (41.4％) and 13 (34％) cases in BR and non-BR group,respectively (P＞0.05).BR in RA was not correlated with clinical parameters and presence of ILD.Logistic regression showed BR [OR:1.201,95％ CI.(1.023-1.411),P＜0.05] and ILD [OR:10.646,95％CI:(1.944-58.305),P＜0.01] were independent risk factors associated with respiratory symptoms in RA pts.Conclusion BR is a common lung lesion in pts with RA in China,and the dose was not correlated with ILD,the number of segment involved by BR is a risk factor for respiratory symptoms.
