AB0309 ASSOCIATION BETWEEN RHEUMATIC DISEASE COMORBIDITY INDEX AND PULMONARY INVOLVEMENT IN RHEUMATOID ARTHRITIS

Background Pulmonary involvement is one of the primary contributors morbi-mortality among patients followed for Rheumatoid Arthritis (RA) [1]. Comorbidities are also independent factors poor outcomes on those debilitated population. Objectives We aimed to assess association between comorbidity and pulmonary in rheumatoid arthritis Methods conducted a retrospective study our rheumatology department including with established RA according ACR/EULAR 2010 criteria. Rheumatic Disease Comorbidity Index (RDCI) was calculated each patient. Clinical characteristics, radiological findings, respiratory function tests (PFTs) were collected. Results There 255 patients: 212 female (83.1%) 43 male (16.9%). The mean age 58.92 ± 10.72 years [25-85]. RDCI 1.14 1.25 [0-6]. noted 115 (45.3%). It asymptomatic 50.6% cases. Reported clinical symptoms dyspnea (36.1%), chronic cough (8.4%), (4.8%). PFT showed restrictive syndrome 34.9% cases, an obstructive 4.8%, mixed 3.6% normal 56.6% patients. Non-specific interstitial pneumonia 26.6% patients, by nodular lung disease 11.4 %, usual 11.4%, BOOP 6.3%, then pleural nodules 6.3%. An (presence: 1.7 1.3 vs absence: 0.6 0.8, p<10 -3 ). Conclusion In conclusion, there elevated index involvement. may be predictive factor extra-articular manifestations. early management improve References [1]Hyldgaard C, Hilberg O, Pedersen AB, Ulrichsen SP, Løkke A, Bendstrup E, et al.A population-based cohort arthritis-associated disease: mortality.
