Madrid, Spain, 12 June 2013: A new study presented at EULAR 2013, the Annual Congress of the European League Against Rheumatism, demonstrates the efficacy of the ARASHI method at evaluating radiographic (X-ray) joint damage in RA.
The study validated the use of ARASHI to assess joint damage in RA, and clarified the pattern of progression of damage during two-year TNF-blocking therapies. In addition to concluding the success of the scoring method, the data also showed that hip and knee joints with pre-existing damage were predisposed to continue destruction, even during two-year treatment with TNF-blocking therapies.
RA is a chronic, inflammatory, autoimmune disease that affects approximately 1 in 100 worldwide. It can cause pain, stiffness, joint destruction and deformity, and reduce quality of life, life expectancy and physical function.
"Radiographic damage is directly correlated to functional disability, overall severity and pain in patients with RA. At present radiographic damage of large joints is commonly evaluated by Larsen grade, which has severe limitations, including a ceiling effect within the grade," commented the study's lead author Dr. Isao Matsushita, Department of Orthopaedic Surgery, Faculty of Medicine, University of Toyama. "These data highlight the need for better scoring and evaluation, without which, progression of damage and patient needs cannot be accurately assessed."
Fifty one patients with a mean age of 59.9 years old were enrolled in the study; each fulfilled the ACR 1987 revised criteria*. Those with a history of surgical intervention were excluded from analysis. Radiographic findings were evaluated at baseline using the ARASHI status score, and at one and two years after TNF-blocking therapies (infliximab, etanercept or adalimumab) using the ARASHI change score.
ARASHI status score consists of 4 categories; joint space narrowing (0-3 points), erosion (0-3 points), joint surface (0-6
