Background: To explore vitamin D(VD) levels in patients with Crohn's disease, and the correlation between VD levels and seasons, disease activity, lesion region, hormone therapy. To find the risk factors of VD deficiency and the role of VD in the pathogenesis and treatment of Crohn’s disease. Methods: Between March 2018 and December 2019, 86 patients diagnosed with CD at the First Affiliated Hospital of Nanjing Medical University were identified, and 86 healthy people were selected as the control group at the same time. VD, counts of white blood cells (WBC), hemoglobin (Hb), counts of platelet(PLT), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), albumin (ALB) levels were recorded at the same time of colonoscopy. Logistic regression analysis of the relationship between disease activity, lesion region, hormone therapy and vitamin D deficiency in patients with Crohn's disease, and analyze possible risk factors. Results: The levels of VD in patients with CD was significantly lower than that in the healthy controls (35.10 nmol/L vs 67.60 nmol/L), the difference was statistically significant (Z= -10.527, P<0.001). The summer autumn group was significantly higher than the winter spring group (z = -2.215, P = 0. 027). Patients with ileum lesions have a higher proportion of vitamin D deficiency than patients with non-ileum lesions. vitamin D deficiency rate of patients in activity stage is higher than that of patients in remission stage. With the increase of the degree of inflammation, the level of vitamin D decreased. Logistic regression analysis shows that platelet count > 250 × 109 /L, CRP ≥ 8 mg / L, ALB < 30 g/L and hormone therapy were risk factors for vitamin D deficiency(P<0.05). Conclusions: Patients with CD have low levels of VD, which is related to seasons. platelet count > 250 × 109 /L, CRP ≥ 8 mg / L, ALB < 30 g/L, and hormone therapy were risk factors for V D deficiency in patient with CD.
