Study of the Laboratory-based Evaluation of the Degrees of Activity of Osteoarthritis

Study of the Laboratory-based Evaluation of the Degrees of Activity of Medium and Large Joint Osteoarthritis

This study evaluates laboratory-based method to estimate the degrees of activity of medium and large joint osteoarthritis.

Osteoarthritis (OA) is a chronic progressive disease, characterized by degradation of joint cartilage, synovial inflammation and joint dysfunction. This study evaluates laboratory-based method to estimate the degrees of activity of medium and large joint OA. Samples of synovial fluid (SF) from the patients with the OA (ICD-10 codes: M15, M16 and M17) will be assessed for T-cell subsets, msast cells, fibroblast-like synoviocytes (FLS) and macrophage-like synoviocytes (MLS) by flow cytometry. Subpopulations of blood T-cells involved in the inflammation will also be assayed. Standard clinical investigation will be performed and the results will be used to estimate the laboratory criteria or degrees of activity of medium and large joint OA.

Inclusion Criteria:

• medium and large joint active osteoarthritis

• refuse of patient to participate in the trial;
• acute infectious diseases;
• pregnancy/lactation;
• intercurrent severe chronic diseases;
• HIV, Hepatites B/C;
• active tuberculosis;
• alcohol use disorder/drug addiction;
• malignant neoplasms/leukemia.
