摘要: 目的 调查非酒精性脂肪性肝病(NAFLD)肥胖儿童血清25羟维生素D3[血清25-(OH)D3]和白介素-17(IL-17)水平变化。方法 2014年1月~2017年12月我院诊治的肥胖儿童62例,参照非酒精性脂肪性肝病诊疗指南标准诊断单纯性非酒精性脂肪肝(NAFL)36例,非酒精性脂肪性肝炎(NASH)26例,另选健康儿童30例,采用ELISA法检测血清25-(OH)D和IL-17水平。结果 NAFL儿童血清25-(OH)D3水平为(15.2±2.1) ng/mL,NASH儿童为(9.6±1.3) ng/ml,均显著低于健康儿童的(26.3±2.3) ng/mL,而血清IL-17水平分别为(17.1±7.8)μg/L和(36.2±12.6) μg/L,均显著高于健康儿童的(1.4±0.5) μg/L,差异均有统计学意义(P<0.05);中度脂肪变儿童血清ALT和AST水平分别为(54.1±15.4) U/L和(46.5±12.6) U/L,重度组儿童分别为(117.1±37.1) U/L和(78.5±31.0) U/L,均显著高于轻度组的(33.4±4.6) U/L和(30.5±2.9) U/L(P<0.05);中度脂肪变儿童血清25-(OH)D3水平为(10.2±1.4) ng/ml,重度组儿童为(8.4±1.1) ng/ml,显著低于轻度组的(15.8±2.0) ng/mL(P<0.05),而血清IL-7水平分别为(22.2±6.3) μg/L和(39.6±9.2) μg/L,显著高于轻度脂肪变儿童的(13.5±3.5)μg/L,组间差异均有显著性统计学意义(P<0.05)。结论 NAFLD儿童血清25-(OH)D3水平降低,而血清IL-17水平升高,它们的变化可能与肝内脂肪变程度有关,动态监测这些变化,可能对了解病情和防治效果判断起指导作用。

Abstract: Objective To investigate serum 25-(OH)D3 and interleukin-17(IL-17) levels in obese children with nonalcoholic fatty liver disease(NAFLD).Methods Sixty-two obese children were enrolled in this study between January 2014 and December 2017,and out of them,36 cases were diagnosed as nonalcoholic fatty liver (NAFL) and 26 were nonalcoholic steatohepatitis (NASH). Thirty healthy children were selected as control. Serum IL-17 and 25-(OH)D3 levels were assayed by ELISA.Results Serum 25-(OH)D3 level in children with NAFL was(15.2±2.1) ng/mL,and in children with NASH was (9.6±1.3) ng/ml,both significantly lower than (26.3±2.3) ng/mL in healthy children,while serum IL-17 levels were(17.1±7.8) μg/L and (36.2±12.6) μg/L,both significantly higher than(1.4±0.5) μg/L in healthy children(P<0.05);serum ALT and AST levels in children with moderate NAFLD were (54.1±15.4) U/L and (46.5±12.6) U/L,and were (117.1±37.1) U/L and (78.5±31.0) U/L in children with severe NAFLD,all significantly higher than (33.4±4.6) U/L and (30.5±2.9) U/L in kids with mild NAFLD(P<0.05);serum 25-(OH)D3 level in children with moderate NAFLD was(10.2±1.4) ng/ml and in children with severe NAFLD was(8.4±1.1) ng/ml,both significantly lower than (15.8±2.0) ng/ml in children with mild NAFLD(P<0.05),while serum IL-7 levels were(22.2±6.3)μg/L and (39.6±9.2) μg/L,respectively,significantly higher than (13.5±3.5) μg/L in children with mild NAFLD (P<0.05). Conclusion Serum 25-(OH)D3 levels decrease and serum IL-17 levels increase in obese children with NAFLD,which might be new indicators for supervision of disease progress.
