Abstract:
Objective: To detect and analyze the expression level of serum 25-hydroxyvitamin D [25(OH)D], periodontal clinical indicators and immunological indicators of rheumatism in patients with periodontitis and rheumatoid arthritis (RA), and to explore the correlation between 25(OH)D and the two diseases. Methods: This study was a case-control study. According to the inclusion criteria, patients from the Department of Stomatology and the Department of Rheumatology and Immunology and healthy volunteers from the Physical Examination Center were selected from November 2018 to May 2019 in Shengjing Hospital, China Medical University respectively. The patients were divided into 4 groups: 26 patients with simple periodontitis were included in the periodontitis group; 23 patients with RA were included in the RA group; 22 patients with RA and periodontitis simultaneously were included in the RA with periodontitis group; 22 healthy volunteers were included in the healthy control group, adding up to a total of 93 cases. The general information and periodontal clinical indexes of subjects in these 4 groups were recorded. Median elbow venous blood samples were collected from fasting subjects in each group, and 25(OH)D and immunoglobulin (Ig) were measured. The disease activity scores of RA patients were recorded and the rheumatic immune indexes were determinated. Pearson correlation analysis was performed between 25 (OH) D level and periodontal indexes in subjects of 4 groups. Results: The expression levels of rheumatoid factor [106.5(47.1, 283.8) kU/L] and C-reactive protein [20.5(13.1, 32.3) mg/L] in RA with periodontitis group were significantly higher than those in RA group [60.1(19.0, 110.0) kU/L, 14.7(3.0, 18.0) mg/L] (Z=-2.29, P=0.022; Z=-2.25, P=0.024). The levels of IgG and IgA in RA with periodontitis group [IgG and IgA: (16.0±4.3), (3.2± 1.3) g/L] as well as RA group [IgG and IgA: (16.3±5.5), (3.7±1.8) g/L] were significantly higher than those in healthy control group [IgG and IgA: (12.0±1.8), (2.3±0.6) g/L] and periodontitis group [IgG and IgA: (12.5±2.2), (2.0±0.7) g/L](P<0.05). The level of 25(OH)D in RA with periodontitis group [(26.0±9.8) nmol/L] was significantly lower than that in periodontitis group [(35.6±8.4) nmol/L] and RA group [(32.7±8.6) nmol/L] (P<0.05). The level of 25(OH)D was negatively correlated with sulcus bleeding index (r=-0.43, P=0.032) and clinical attachment loss (r=-0.41, P=0.043). Conclusions: Expression level of 25(OH)D was significantly decreased in patients with periodontitis and RA. There was a certain correlation between 25(OH)D and periodontitis and RA.
