ABSTRACT
Background:
Rheumatoid arthritis (RA) is a chronic inflammatory arthropathy characterized by excessive synovial hyperplasia and progressive joint destruction. Pro-inflammatory cytokines play major roles in the regulation of synovial inflammation. The contribution of interleukin-34 (IL-34) in RA pathogenesis has been strongly suggested in clinical studies.Aim:
To investigate the correlation between plasma IL-34 and disease parameters in RA patients including disease activity score (DAS28), receptor activator of NF-[Formula see text]B ligand (RANKL) concentration, synovitis and bone erosions under ultrasound.Methods:
60 RA patients and 20 healthy controls were from Huashan Hospital, patient's medical history, physical examination, laboratory examination and ultrasound data were collected and recorded, respectively. Blood samples of all participants were collected and the levels of IL-34 and RANKL were tested. The levels of IL-34 and RANKL in RA patients were compared with those of healthy controls. Furthermore, the correlation between IL-34, RANKL and disease parameters in RA patients was analyzed.Results:
Both plasma levels of IL-34 and RANKL in RA patients were significantly higher than the healthy controls (p < .05). IL-34 was significantly related to disease activity scores (r = 0.43, p = .001); RANKL (r = 0.46, p = .0003) and bone erosions by ultrasound (r = 0.38, p = .002).Conclusions:
The plasma IL-34 concentration in RA was significantly higher than the healthy controls and was significantly correlated with RANKL, as well as disease activity score and bone erosions by ultrasound. The IL-34 may be a new biological marker for disease activity and predictor for bone erosions in RA. Targeting IL-34 holds promise in the management of RA and, potentially, other osteoclasts driven diseases (erosive osteoarthritis and psoriatic arthritis for example).Palavras-chave
