ABSTRACT
BACKGROUND AND AIM:
The association between vitamin D status and osteoarthritis (OA) and bone remodeling has been shown previously. The present study was conducted to determine the association between vitamin D status and inflammatory biomarkers and clinical symptoms in patients with knee OA.METHODS:
This case-control study was performed on 124 subjects with mild to moderate knee OA and 65 healthy controls. Demographic data was collected from all participants at baseline. We used Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC Index) for evaluating the severity of clinical symptoms in these patients. Serum levels of vitamin D as well as markers of inflammation including interleukin 1-ß (IL-1ß), interleukin 6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor-alpha (TNF-α), high-sensitivity C-reactive protein (hs-CRP), and nuclear factor k-B (NF-κB) p65 were evaluated for each participant.RESULTS:
The results of the present study showed that patients with knee OA had lower levels of vitamin D and higher levels of IL-1ß, TNF-α, hs-CRP, and NF-кB p65 compared with healthy controls (P < 0.0001). The levels of IL-1ß, TNF-α, and NF-кB p65 in knee OA patients with vitamin D insufficiency were significantly higher compared with the knee OA patients with sufficient vitamin D (P < 0.05). Based on the linear regression analysis, serum vitamin D levels were inversely correlated with IL-1ß, TNF-α, hs-CRP, and NF-кB p65 levels (P < 0.0001). Patients with sufficient vitamin D levels had lower total and physical function WOMAC scores compared with patients with vitamin D insufficiency (P = 0.011 and P = 0.010, respectively).CONCLUSION:
The results suggest a strong link between vitamin D deficiency and increased inflammatory biomarkers as well as increased severity of clinical symptoms in knee OA patients.Palabras clave
