Abstract

Objective. The Disability of Ann, Shoulder and Hand (DASH) questionnaire is a tool for measuring physical function and symptoms of the upper extremity. Although widely used, it is not validated for rheumatoid arthritis (RA). In this study the DASH was validated for this patient group. Methods. In total, 102 patients participated in this study. For the validation, the questionnaires of the DASH, the Health Assessment Questionnaire (HAQ), the Medical Outcomes Study Short Form-36 (SF-36), and the Arthritis Impact Measurement Scale (ATMS2) were used. Patients were examined clinically before completing the questionnaires. Pain was scored by each patient using a visual analog scale (VAS). The Disease Activity Score (DAS28) was obtained and grip strength was measured. Reliability was tested by a second DASH questionnaire after 2 days. Validity was tested using a Pearson correlation analysis for the relevant domains of the questionnaires and for the clinical aspects. Results. The reliability of the DASH was excellent (intraclass correlation coefficient 0.97). Internal consistency was strong (Cronbach's alpha 0.97). Validity was proven with excellent results for Pearson correlation with the relevant domains of the questionnaires: HAQ, r = 0.88; SF-36, r = 0.70; and AIMS2, r = 0.85. The clinical scores had a relatively low correlation with the DASH (DAS28, r = 0.42; and grip strength, r = 0.41-0.48), except for the VAS (r = 0.60-0.65). Conclusion. The DASH is a reliable and valid questionnaire in patients with RA. It can be used as a measurement tool of physical disability of the upper extremity.

Hand and Wrist Involvement in Seropositive Rheumatoid Arthritis, Seronegative Rheumatoid Arthritis, and Psoriatic Arthritis-The Value of Classic Radiography

Ewa Zelnio, Mihra Taljanovic, Malgorzata Manczak, Iwona Sudol-Szopinska

Summary: The hand and wrist are frequently involved in rheumatic diseases, and this study aimed to identify the distinguishing radiographic characteristics of psoriatic arthritis (PsA), seropositive rheumatoid arthritis (RA), and seronegative RA, especially in the early stages. The analysis of radiographic hand findings on 180 seropositive RA patients, 154 PsA patients, and 36 seronegative RA patients revealed that symmetric distribution of lesions was more suggestive of seropositive or seronegative RA, while lesions affecting PIP joints, wrist, or styloid process of the radius were more common in patients with seropositive RA. PsA was more likely to be suggested by DIP joints' involvement and proliferative bone changes. Furthermore, there were differences in the types of bone lesions and their distribution between seropositive RA, seronegative RA, and PsA, with ulnar styloid involvement more commonly seen in seronegative RA patients.
