ABSTRACT
Objective:To explore the relationship of Vitamin A and Vitamin D with the incidence and severity of hand, foot and mouth disease(HFMD) as well as with the anti-viral immune index interferon-α(INF-α), and to investigate the role of Vitamin A and Vitamin D in HFMD.Methods:A total of 305 children with Coxsackie virus A6(CA6) HFMD admitted at Xi′an Children′s Hospital from January 2017 to December 2018 were enrolled in the study.One hundred healthy children whose gender and age matched with those of children in the case group were selected as the healthy control group.Serum Vitamin A levels were detected by high performance liquid chromatography.Enzyme-linked immunosorbent assay was used to detect the levels of Vitamin D and IFN-α, and the correlation of the levels of Vitamin A and Vitamin D with the severity of HFMD was analyzed.Results:The levels of serum Vitamin A[(0.96±0.39) mg/mol] and Vitamin D [(42.14±15.13) μg/L] in patients with CA6 HFMD were lower than those of the healthy control group[(1.26±0.29) mg/mol, (49.63±8.86) μg/L], and the differences were statistically significant(all P<0.05). Logistic multivariate regression analysis showed that WBC>15×10 9/L, blood sugar>8.3 mmol/L, the deficiency of Vitamin A level and Vitamin D level were all risk factors for severe CA6 HFMD in children( OR=2.303, 4.622, 7.346, 5.211; all P<0.05). According to the receiver operating characteristic curve analysis, the Youden index was the largest at a Vitamin A level of 0.725 mg/mol, and the corresponding sensitivity and specificity were 82.0% and 64.8%, respectively.When Vitamin D level was 32.88 μg/L, the Youden index was the highest, and the sensitivity and specificity were 84.5% and 61.9%, respectively.The serum IFN-α concentration of patients with CA6 HFMD [(84.44±26.28) ng/L] was higher than that of the healthy control group [(36.58±14.39) ng/L], and the difference was statistically significant( P<0.05). In addition, the serum IFN-α concentration in severe HFMD children [(71.48±18.34) ng/L] was significantly lower than that in the common HFMD children [(91.25±27.27) ng/L], and the difference was statistically significant( P<0.05). The results of correlation analysis showed that serum IFN-α concentration is positively correlated with Vitamin A and Vitamin D levels ( r=0.783, 0.239; all P<0.001). Conclusions:The levels of serum Vitamin A and Vitamin D decreased in children with HFMD.WBC>15×10 9/L, blood sugar>8.3 mmol/L, the deficiency of Vitamin A level and Vitamin D level are related to severe HFMD.The se-rum IFN-α concentration is positively correlated with the levels of Vitamin A and Vitamin D. The deficiency of Vitamin A and Vitamin D is one of the early warning factors of severe HFMD.
