Down's Syndrome patients are known to be of short stature, prone to infections, autoimmune disease, hypothyroidism, leukaemia, heart defects and later Alzheimer's disease. They tend to have older mothers, like Alzheimer's disease patients. The latter tend to have sibs with either Down's Syndrome or lymphoma/leukaemia. Evidence, looking at 28 Down's Syndrome patients, suggests that multiple food allergies, gluten-gliadin sensitivity or intolerance are causing a coeliac disease-like picture with a malabsorption state for essential vitamins, minerals and severe autoimmune disease. It is hoped that missed gluten-gliadin sensitivity or intolerance with or without coeliac disease will be considered as a cause of abnormal oogenesis and spermatogenesis resulting in trisomy 21 and other aneuploidies. The mechanism most likely is low B1 interfering with sufficient release of cAMP for normal meiosis. Alternatively exorphins and peptides from foods may suppress prostaglandin E1 synthesis, or food sensitivities may alter toxic metal absorption mechanisms, which are thought to play a role in the development of Alzheimer's disease. Adequate vitamin/mineral supplementation, especially B1, prior to conception and in the first trimester is recommended for mothers at risk for DS, especially older mothers and a gluten free diet for those with coeliac disease or gluten-gliadin sensitivity/intolerance. Hopefully this will prevent conception of a DS child, or prevent heart defects/stigmata if one is conceived. DS children should be investigated for the above and commence a food allergy free diet with relevant supplements to meet their needs as early as maximum development.
众所周知,唐氏综合征患者身材矮小,容易感染、患自身免疫性疾病、甲状腺功能减退、白血病、心脏缺陷,后期还易患阿尔茨海默病。他们往往有年龄较大的母亲,这一点与阿尔茨海默病患者相似。后者往往有患唐氏综合征或淋巴瘤/白血病的兄弟姐妹。对28名唐氏综合征患者的研究证据表明,多种食物过敏、麸质醇溶蛋白敏感性或不耐受会导致类似乳糜泻的症状,出现必需维生素、矿物质吸收不良以及严重的自身免疫性疾病。人们希望,无论是否患有乳糜泻,未被发现的麸质醇溶蛋白敏感性或不耐受将被视为导致卵子发生和精子发生异常从而导致21三体和其他非整倍体的原因。最有可能的机制是低水平的维生素B1干扰了正常减数分裂所需的环磷酸腺苷(cAMP)的充分释放。另外,食物中的外啡肽和肽可能会抑制前列腺素E1的合成,或者食物敏感性可能会改变有毒金属的吸收机制,而这些机制被认为在阿尔茨海默病的发展中起作用。建议有唐氏综合征风险的母亲,尤其是年龄较大的母亲,在受孕前和孕早期补充足够的维生素/矿物质,特别是维生素B1,对患有乳糜泻或麸质醇溶蛋白敏感性/不耐受的母亲建议采用无麸质饮食。希望这将防止怀上唐氏综合征患儿,或者如果已经怀上,能预防心脏缺陷/体征。应该对唐氏综合征患儿进行上述检查,并尽早开始无食物过敏饮食并补充相关营养以满足其最大发育需求。
