AB1130 LOCALIZATION OF MRI INFLAMMATORY LESIONS OF THE HAND IN SCLERODERMA AND RHEUMATOID ARTHRITIS - COMPARATIVE STUDY

Background: Inflammatory lesions of hand are frquent clinical feature in rheumatoid artritis (RA), with lower frequency in pts with systemic sclerosis (SSc), also. MR is useful method for detecting and quantification of inflammatory lesion of the hand (bone oedema, erosions, synovitis) in RA and SSc. Objectives: The aim of the study was to compare MR hand feature in SSc (experimental) and RA (control group) and to detect the localisation of the highest OMERACT RAMRISinflammatory score on the hand in pts with SSc and RA Methods: 110 pts with SSc and 60 with RA were investigated (mean age 53y). All the pts underwenr clinical examination, X ray and MR on the dominant hand and wrist. Contrast enhanced low field MRI of the wrist and MCP2-5 joints was performend to all the pts. MRI inflammatory changes (bone oedema,erosions, synovitis)were assessed and scored by OMERACT RAMRIS scoring system. Results: Clinical examination confirmed synovitis in 17.1%, and 78% of patients with SSc using MR I (p Conclusion: MR inflammatory lesions in SSc are less frequent compared to that in RA but still in significant percentage, confirming the need for early detection and aggressive treatment of both, RA and SSc patients with joint involvement References: [1]Avouac J, Walker UA, Hachulla E, Riemekasten G, Cuomo G, Carreira PE, et al.
