Vitamin B6 as a novel risk biomarker of fractured ankles

Abstract

Ankle fractures are the most common intra-articular fractures. Osteoporosis is a common and frequent disease among the elderly with a poor prognosis and high risk of fractured ankles. However, the relationship between vitamin B6 and the incidence of fractured ankles in patients with osteoporosis is unclear.A total of 101 patients with osteoporosis were recruited. Clinical and followed-up information was recorded. And the vitamin B6, albumin, globulin, and hemoglobin in the blood were tested. Pearson's chi-squared and spearman test were performed to analyze the correlation between fractured ankles and relative parameters. Univariate and multivariate logistic regression, receiver operating characteristic curve analysis, univariate and multivariate Cox proportional hazards regression analysis, and Kaplan-Meier method were also performed.There exist strong relation between the expression level of vitamin B6 and fractured ankle (P < .001). The expression of vitamin B6 [Odd ratio (OR) = 12.071, 95% confidence interval (CI): 4.69-31.143, P < .001] has a clear correlation with whether the patients have fractured ankles via the univariate logistic regression analysis. In terms of multivariate logistic regression level, vitamin B6 (OR = 15.384, 95% CI:5.195-45.556, P < .001) was significantly associated with fractured ankle. In addition, expression level of vitamin B6 [hazard ratio (HR) = 11.684, 95% CI: 6.419-21.267, P < .001] was significantly associated with Maintenance time from recovery to recurrence (MRTT) of patients with osteoporosis.Enhanced vitamin B6 is significantly correlated with the poor prognosis of patients with osteoporosis and the increasing incidence of fractured ankles.
