Abstract:

Objective To investigate the changes of serum 1,25-dihydroxyvitamin D3 [1,25(OH)2D3],interleukin (IL)-17 and IL-10 in patients with osteoarthritis (OA). Methods A total of 91 OA patients and 80 healthy subjects (healthy control group) were enrolled. The levels of 1,25(OH)2D3,IL-17 and IL-10 were determined by enzyme-linked immunosorbent assay (ELISA). The level of 25-hydroxyvitamin D3 [25(OH)D3] was determined by electrochemiluminescence. Visual analogue scale (VAS) was used for the scoring of OA patients. The correlations among 1,25(OH)2D3,VAS,IL-17 and IL-10 were analyzed by Spearman correlation analysis. Results Serum levels of 1,25(OH)2D3,25(OH)D3 and IL-10 were lower in OA group than those in healthy control group (P<0.05),and serum level of IL-17 in OA group was higher (P<0.05). According to the levels of 25(OH)D3,the patients were classified into 3 groups,vitamin D deficiency,vitamin D insufficient and vitamin D adequacy groups. The VAS score of vitamin D deficiency group was higher than those of vitamin D insufficient and vitamin D adequacy groups (P<0.05),and there was no statistical significance for the VAS score between vitamin D insufficient and vitamin D adequacy groups (P>0.05). According to VAS scores,the patients were classified into mild pain,moderate pain and severe pain groups. Serum levels of 1,25(OH)2D3 in severe pain and moderate pain groups were lower than that in mild pain group (P<0.05),and there was no statistical significance between severe pain and moderate pain groups (P>0.05). Spearman correlation analysis showed that 1,25(OH)2D3 was positively correlated with IL-10 (r=0.778,P=0.002),and it was negatively correlated with VAS and IL-17 (r=-0.691 and -0.735,P=0.01 and 0.007). VAS score was negatively correlated with IL-10 (r=-0.725,P=0.008) and positively correlated with IL-17 (r=0.699,P=0.010). Serum levels of 1,25(OH)2D3 and IL-10 in patients with OA after treatment were higher than those before treatment (P<0.05),but they were lower than those in healthy control group (P<0.05). Serum levels of IL-17 after treatment were lower than those before treatment (P<0.05),but they were higher than those in healthy control group (P<0.05). Conclusions Serum 1,25(OH)2D3 plays a role in the occurrence and severity of OA.
