The purpose of this study was to investigate the effects of vitamin D in rat models of chronic obstructive pulmonary disease (COPD) and periodontitis. Animals with both periodontitis and COPD, or with periodontitis only, were established. Once the animal model was established, experimental groups received intraperitoneal injections of 25-hydroxyvitamin D3 (25-OHD3) for 8 weeks, while control groups received refined peanut oil. After sacrifice, inflammatory status was examined in terms of the serum levels of receptor activator of the nuclear factor kappa B ligand (RANKL), tumor necrosis factor alpha (TNF-alpha) and interleukins (IL-1 and IL-10), as well as alveolar bone loss, forced expiratory volume (0.20) (FEV 0.20), and the ratio of FEV0.2 to forced vital capacity. The results showed that 25-OHD3 treatment significantly alleviated inflammation by decreasing the serum levels of RANKL, TNF-alpha and IL-1 and increasing that of IL-10, while reducing alveolar bone loss and slightly improving lung function. These findings suggest that vitamin D supplementation could he a new clinical approach for the treatment of COPD and periodontitis.
