孕妇剧烈呕吐可能是家族遗传

cnbabyup报道,BMJ 2010;340:c2050。孕妇妊娠期间常会出现恶心和呕吐现象,但某些孕妇的剧烈呕吐往往需要送医院治疗。一项最新研究显示,这种被称为妊娠剧吐的症状会由妈妈传给女儿,它很可能具有家族遗传性。

新一期《英国医学杂志》(BMJ)刊登报告说,挪威研究人员分析了该国过去几十年里230万份出生记录,以及相应孕妇的健康数据,结果发现,如果母亲怀孕期间出现妊娠剧吐症状,女儿后来怀孕时也出现该症状的可能性是其他人的约3倍。

据介绍,妊娠剧吐会导致孕妇体重下降、缺少维生素和营养不良,如不及时医治还可能导致早产并影响婴儿健康。

研究还发现,孕妇妊娠剧吐与腹中胎儿含有来自丈夫一方的相关基因没有关系,导致这一症状的基因可能只是由妈妈遗传给女儿。

不过研究人员也表示,目前还不能完全排除环境因素的影响,因为母亲和女儿很可能生活在类似的环境中或是有相似的生活习惯,从而出现妊娠剧吐症状。

Recurrence of hyperemesis gravidarum across generations: population based cohort study

Hyperemesis gravidarum (hyperemesis) is defined as excessive nausea and vomiting in pregnancy starting before the 22nd week of gestation, which might lead to nutritional deficiencies and weight loss. Hyperemesis occurs in 0.5-2.0% of pregnancies and is the most common cause of admission to hospital in early pregnancy. It is associated with adverse pregnancy outcomes such as low birth weight and preterm birth.The aetiology is unknown.A study using the medical birth registry of Norway found that the risk of hyperemesis in a woman’s second pregnancy was 15.2% if hyperemesis had occurred in the first, compared with only 0.7% if it had not occurred.For women with hyperemesis in the first pregnancy, the risk of hyperemesis in the second pregnancy was 10.9% after a change of partner, while it was 16.0% if the partner remained the same. These findings suggest that there might be a genetic aspect to hyperemesis, possibly involving both maternal and fetal genes, although environmental factors cannot be ruled out.

To extend our understanding of the aetiology of this condition we examined the risk of hyperemesis according to whether or not the women and men under study were born after pregnancies complicated by hyperemesis. In addition, we estimated the risk of hyperemesis in women born after pregnancies not complicated by hyperemesis but where their mothers had hyperemesis in a previous or later pregnancy.
