Recognition of liver dysfunction relies on the creation of reference ranges. Outside pregnancy, factors such as age and gender have been shown to affect liver biomarkers but despite recommendations for age and gender-adjusted reference ranges for liver function tests, these have not been widely adopted clinically. In pregnancy, there are only a few studies that have examined changes of liver function tests (LFTs) with gestation, and none of them have controlled for maternal demographic characteristics.</p><p><strong>Objectives: </strong>The aims of this study are first, to provide reference ranges of LFTs in a large population of uncomplicated pregnancies after adjusting for the effect of gestational age and maternal demographic characteristics on the median and measures of dispersion and shape (skewness and kurtosis) of the distribution of these variables, and second, to create an on-line calculator of z-scores of maternal LFTs using the above-mentioned methodology.</p><p><strong>Study design: </strong>This was a cross-sectional study of healthy women attending for routine antenatal ultrasound scans at 11<sup>+0</sup> to 13<sup>+6</sup> weeks' gestation (visit 1), 19<sup>+0</sup> to 24<sup>+6</sup> weeks (visit 2), 30<sup>+0</sup> to 34<sup>+6</sup> weeks (visit 3), and 35<sup>+0</sup> to 37<sup>+6</sup> weeks (visit 4). Women with a history of liver dysfunction or adverse pregnancy outcome were excluded from the analysis. We measured the following variables: alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT), total bilirubin (TBIL) and albumin (ALB). The assessment of the distribution of LFTs across gestational age, (controlling for maternal characteristics) was performed with Generalized Additive Models for Location, Scale, and Shape (GAMLSS), using the GAMLSS R package, which allows the implementation of distributions other than normal distribution.</p><p><strong>Results: </strong>There were 3451 women who agreed to participate in the study and had uncomplicated pregnancies.

Identifying an effective, safe, and affordable method to prevent hyperemesis gravidarum is critical to reducing risk of reoccurrence and improving maternal, fetal, and child health. We recently demonstrated that genetic predisposition to hyperemesis gravidarum is mediated by low pre-pregnancy levels of the emetogenic hormone Growth and Differentiation Factor 15, resulting in hypersensitivity to its rapid rise during pregnancy. Because metformin increases circulating levels of the Growth and Differentiation Factor 15, we hypothesized that use of metformin before pregnancy will desensitize patients to the hormone and lower the risk of severe nausea and vomiting in pregnancy and hyperemesis gravidarum.","PeriodicalId":7574,"journal":{"name":"American journal of obstetrics and gynecology","volume":"27 1","pages":""},"PeriodicalIF":9.8,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
