Serum urate in degenerative joint disease and rheumatoid arthritis

Comparative studies of serum polysaccharides in rheumatoid arthritis and degenerative joint disease.

Serum YKL-40 levels and disease characteristics in patients with rheumatoid arthritis

Background: The present study aimed to evaluate serum YKL-40 levels in patients with rheumatoid arthritis (RA) compared to healthy subjects and to search whether there is an association between YKL-40 levels and disease characteristics in RA. Methods: In this cross-sectional study, 60 RA patients based on the ACR/EULAR 2010 criteria and 30 age- and sex-matched healthy controls were included. I...

25(OH) vitamin D serum values and rheumatoid arthritis disease activity (DAS28ESR)

Background: The role of vitamin D in the pathogenesis of rheumatoid arthritis is under investigation. This study was designed to evaluate the correlation between serum values of 25(OH) vitamin D [25(OH)D] and disease activity in rheumatoid arthritis (RA) patients according to Disease Activity Score 28 joints and ESR (DAS28ESR). Methods: Ninety-nine patients according to ACR classification crit...

Correlation between Serum Levels of Calprotectin with Disease Activity in Rheumatoid Arthritis Patients

Background and Objective: Rheumatoid arthritis (RA) is an autoimmune disease defined by chronic synovitis and progressive joint destruction. This study investigated calprotectin as a serological marker in the hope of establishing an adequate means of diagnosing RA and following up on patients. Materials and Methods: This cross-sectional study included 32 RA patients who were referred to the rh...

Radiographic evaluation of arthritis: degenerative joint disease and variations.

In the presence of joint space narrowing, it is important to differentiate inflammatory from degenerative conditions. The presence of osteophytes, bone sclerosis, and subchondral cysts and the absence of inflammatory features such as erosions suggest osteoarthritis. Typical osteoarthritis involves specific joints at a particular patient age. When osteoarthritis involves an atypical joint, occur...
