研究目的: |
维生素A缺乏在全世界广泛流行,尤其是发展中国家更为严重,导致全球每年60万儿童死亡。我国城乡3~12岁儿童维生素A缺乏和边缘缺乏率达54.4%,农村为60.8%;农村80%以上六月龄内婴儿维生素A营养不良。维生素A补充可显著降低维生素A缺乏地区儿童死亡率,还可促进儿童对多种疫苗的免疫应答。乙肝疫苗接种是我国控制乙肝的最重要措施,但婴幼儿中广泛的V维生素A营养不良是否会制约乙肝疫苗免疫效果,目前尚无研究。本研究将采用随机、双盲、安慰剂对照的现场干预试验,选择150 例农村乳母及其母乳喂养婴儿为研究对象,随机分为三组,从产后两周直到产后六个月,分别给予乳母分次大剂量、每日小剂量维生素A补充以及安慰剂,观察母乳中维生素A含量变化,母乳喂养儿童血清维生素A水平改善,以及婴儿完成三次乙肝疫苗接种后一个月时血清抗乙肝疫苗抗体浓度,分析三组间的差别。结果将有助于阐明我国儿童维生素A营养不良是否制约了乙肝疫苗的免疫效果。 |

Objectives of Study: |
Vitamin A deficient (VAD) children have impaired immunity. Vitamin A (VA) supplementation has been associated with enhancing anti-body response to tetanus toxoid and diphtheria, measles and Hepatitis B vaccine. VAD is highly prevalent in China, about 39.4% and 44.8% of rural infants under-6-months were VAD and marginal VAD. Meanwhile, the prevalence of Hepatitis B virus infection was about 9.09% in China. Hepatitis B vaccine has been incorporated into China’s National Immunization Program since 2002. But 1.89%~63.06% of young children manifested weak or null response to the vaccine. Thus, research is needed to assess the impact of vitamin A status on response to the vaccine. The overall goal of this study is to assess the effects of maternal VA supplementation during lactation on their offspring’s vitamin A status and immune response to Hepatitis B vaccine. This is a randomized, double-blind, controlled intervention trial. Lactating women (n=150) are recruited before giving birth and randomly assigned to one of the following three groups: 1) large doses VA supplements (60mg) each at 2 weeks and 3 months postpartum; 2) daily VA supplements (1.2 mg) for 6 months; or 3) no any VA supplements. In addition, all of the mothers will be given daily a capsule containing 10 mg alpha-tocopherol and 10μg cholecalciferol in corn oil. Blood samples will be collected from the infants at 1 month after the 3rd Hepatitis B vaccine to analyze plasma anti-Hepatitis B antibody, retinol and acute phase proteins (C-reactive protein and alpha-acid glycoprotein). Maternal venous blood will be collected to analyze plasma retinol concentration at the beginning and the end of the study. Breast milk samples will be collected from the mothers at the beginning, mid and end of the treatment period to analyze breast milk retinol. |
