Effects of nonsteroidal anti-inflammatory drugs on serum proinflammatory cytokines in the treatment of ankylosing spondylitis

摘要

Objective: This study was conducted to investigate the correlation between serum levels of proinflammatory cytokines and the clinical efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with ankylosing spondylitis (AS). Methods: A total of 148 patients with AS were selected and received NSAID treatment. ELISA was used to assess cytokine levels, and patients were assigned into the following groups: positively effective; effective; moderately effective; and ineffective. Spearman and Pearson correlation analyses were used for correlation analysis. Results: The erythrocyte sedimentation rates (ESR), C-reactive protein (CRP) levels, and immunoglobulin A (IgA) levels of the case group after NSAID treatment were markedly lower than those before NSAID treatment. After treatment, the levels of interleukin (IL)-6 IL-17, and tumor necrosis factor (TNF)-alpha were markedly reduced, while IL-10 levels increased in the positively effective, effective, and moderately effective groups, and IL-12 levels decreased in the positively effective and effective groups. In addition, the levels of IL-6 and TNF-alpha were correlated with a greater number in the efficacy indexes and clinical parameters, followed by IL-10 levels, while the levels of IL-17 and IL-12 had relatively weaker correlations with these indexes and parameters. Conclusion: NSAIDs could promote the clinical efficacy of treatment for ankylosing spondylitis by regulating serum levels of proinflammatory cytokines.
