About this trial
To evaluate serum and synovial fluid 15-PGDH levels in patients with osteoarthritis and ankylosing spondylitis and determine their associations with clinical and musculoskeletal ultrasound features.
To compare 15-PGDH concentrations among patients with knee osteoarthritis, and ankylosing spondylitis with knee effusion
To evaluate whether serum 15-PGDH reflects intra-articular 15-PGDH concentrations.
Analysis the level of 15-PGDH in relation to disease activity and severity of both diseases.
