Abstract

Abstract : Background: Osteoarthritis (OA) and rheumatoid arthritis (RA) are the most frequent inflammatory diseases of the musculoskeletal system, which could not be differentiated in their early stages, and characterized by degradation of articular cartilage and impairment of joint function. Sometimes, criteria and radiography are not insufficient to distinguish early-stages of RA and OA and predict disease course, and therefor biomarkers that help clinicians to early diagnose disease are essential. Objectives: The aim of this study is to estimate serum level of Matrix metalloproteinase 3 (MMP3) and hrdroxyproline (HP) in early RA and OA patients to see if they can be used to differentiate both diseases at their early stages Methods: The aim of this study is to estimate serum level of Matrix metalloproteinase 3 (MMP3) and hrdroxyproline (HP) in early RA and OA patients to see if they can be used to differentiate both diseases at their early stages Results: We found a highly significant elevation of serum MMP3 in OA patients group compared to RA patients and control groups. We also found a highly significant elevation of MMP3 in RA patients than control group, (P < 0.001). Meanwhile, we found a highly significant elevation of HP in OA patients than in RA patients and control groups, (P < 0.001), whereas there was no significant difference between HP in RA patients and control groups (P > 0.05). Conclusion: Our results suggest that serum levels of Hydroxyproline (HP) rather than MMP3 could be used as a potential biomarker for early differentiation between osteoarthritis (OA) and rheumatoid arthritis (RA) when diagnostic criteria failed to be fulfilled.
