Abstract:
Objective The aim of this study was to explore the serum 25-(OH) Vitamin D and its correlation with liver function in children who have suffered from non-alcoholic fatty liver disease (NAFLD),and to explore the necessity of vitamin D treatment of NAFLD in children.Methods Forty children with NAFLD diagnosed by imaging were selected from the outpatient of pediatric digestive department of Shengjing Hospital of China Medical University,selected as observation group from July 2017 to August 2019,and 37 healthy children were selected as control group.The clinical data were collected and serum 25-(OH) Vitamin D were detected at the same time.Results There was no significant difference in 25-(OH) Vitamin D among children with NAFLD at different ages and gender (P ＞ 0.05).The level of 25-(OH) Vitamin D in children with NAFLD [(21.30 ±8.77) μg/L]was significantly lower than that in the control group [(28.53 ± 10.18) μg/L] (t =3.343,P ＜ 0.01).The incidence of vitamin D deficiency (＜ 20 μg/L) and insufficiency (＜30 μg/L)in children with NAFLD (35/40 =87.50％) was significantly higher than that in the control group (22/37 =59.46％) (x2 =10.035,P ＜ 0.05).Serum 25-(OH) Vitamin D was negatively correlated with fasting insulin (r =-0.464,P ＜ 0.01) and homeostasis model assessment of insulin resistance (r =-0.444,P ＜0.01),but not correlated with BMI,transaminase level (ALT,AST),uric acid and blood lipid (TG,TC,HDL-C,LDL-C,sd-LDL,Apo-A1,Apo-B).Vitamin D deficiency was the risk factor of NAFLD (OR =1.088,P ＜ 0.01).Conclusion Vitamin D deficiency is common in pediatric NAFLD,which may be a risk factor of NAFLD.The mechanism may be that vitamin D deficiency aggravates insulin resistance and further aggravates liver damage in children with NAFLD.
