Abstract:
Objective:To investigate the changes and clinical significance of serum immunoregulatory cytokines in patients with rheumatoid arthritis (RA) complicated with osteoporosis (OP).Methods:The clinical data of 420 patients with RA admitted to Mianyang Central Hospital from January 2019 to December 2019 were analyzed. According to their bone mineral density, they were divided into OP group (220 cases) and non OP group (200 cases). The immunoregulatory cytokines and bone metabolism indexes of the two groups were compared, and the correlation between them was analyzed.Results:The age, course of disease, glucocorticoid use history, fracture history, swelling joint number and tenderness joint number of OP group were significantly higher than those of non OP group ( P<0.05). In OP group, the serum levels of interleukin (IL)-6, IL-17, tumor necrosis factor-α (TNF-α) and C-terminal peptide cross-linking (CTX) of type Ⅰ collagen were significantly higher than those in control group ( P<0.05), while the IL-10 and transforming growth factor-β1 (TGF-β1) were significantly higher than that of non OP group ( P<0.05). The serum level of CTX in patients with RA complicated with OP was positively corrected with IL-6, IL-17, TNF-α ( r=0.913, 0.915, 0.921, P<0.001), and negatively correlated with IL-10 and TGF-β1 ( r=-0.921, -0.920, P<0.001). Conclusions:RA patients complicated with OP have higher age, longer course of disease, history of fracture, history of glucocorticoid use, more joint swelling and pain, higher IL-6, IL-17, TNF-α levels, lower IL-10 and TGF-β1 levels. Immunoregulatory cytokines may regulate the proliferation and differentiation of osteoclasts and osteoblasts, and play an important role in RA complicated with OP.
