Synovial tissue macrophage as a source of the chemotactic cytokine IL-8
Key result
Rheumatoid arthritis was associated with significantly higher IL-8 levels in synovial fluid compared to osteoarthritis (14.37 vs 0.135 ng/ml, p<0.05), primarily derived from synovial macrophages.

Implication
IL-8 may drive synovial inflammation in RA; leaves open its value as biomarker or therapeutic target.

Koch et al. (1991) conducted an observational in Arthritis (Rheumatoid arthritis, Osteoarthritis) (n=75). Rheumatoid arthritis vs. Osteoarthritis was evaluated on IL-8 levels in synovial fluid (ng/ml) (p=<0.05). Rheumatoid arthritis was associated with significantly higher IL-8 levels in synovial fluid compared to osteoarthritis (14.37 vs 0.135 ng/ml, p<0.05), primarily derived from synovial macrophages.
