OBJECTIVE: To investigate the effect of vitamin D deficiency on susceptibility to spinal tuberculosis and its pathological development.
METHODS: A case-control design was used in this study. A total of 163 treatment-naïve patients with spinal tuberculosis admitted to this institute for an operation from June 2013 to May 2016 were included in the case group, and 170 subjects who received a health examination in the same hospital were included in the control group. Control group patients were frequency-matched with the case group by age, gender, and season. Serum 25-hydroxyvitamin D levels were detected using an enzyme linked immunosorbent assay (ELISA). Pathological classification of patients in the case group was conducted according to intraoperative findings, and definite diagnosis of spinal tuberculosis was confirmed after operation.
RESULTS: The serum level of vitamin D [23.99 (20.55, 29.54) nmol/L] in the case group was lower than that in the control group [42.94 (35.68, 51.04) nmol/L], and the difference was statistically significant (Z = -9.048, P < 0.05). Out of the 163 patients with spinal tuberculosis who underwent pathological classification, 107 cases of caseous necrosis and 56 cases of hyperplasia were identified. Based on the vitamin D levels of the patients in the case group, these patients were further divided into a low-level group (<25 nmol/L) and a high-level group (≥25 nmol/L). The proportion of patients with caseous necrosis in the low-level group (79.17%) was higher than that in the high-level group (46.27%), with a statistically significant difference (χ2 = 18.937, P < 0.05).
CONCLUSION: Vitamin D deficiency is associated with susceptibility to spinal tuberculosis and its pathological classification, and vitamin D deficiency affects the occurrence and development of spinal tuberculosis.
