Multi-ancestry GWAS of severe pregnancy nausea and vomiting identifies risk loci associated with appetite, insulin signaling, and brain plasticity.

While most pregnancies are affected by nausea and vomiting, hyperemesis gravidarum (HG) is at the severe end of the clinical spectrum and is associated with dehydration, undernutrition, and adverse maternal, fetal, and child outcomes. Herein we performed a multi-ancestry genome-wide association study (GWAS) of severe nausea and vomiting of pregnancy of 10,974 cases and 461,461 controls across European, Asian, African, and Latino ancestries. We identified ten significantly associated loci, of which six were novel (, , , , , and , and confirmed previous genome-wide significant associations with risk genes , , , and .

Pregnant, miserable, and starving in 21st century America.

Severe nausea and vomiting of pregnancy is too common and devastating to be trivialized any longer. Authors of recent studies observed that children exposed in utero to severe nausea and vomiting of pregnancy had an increased risk for autism spectrum disorder, a decreased brain cortical volume, and developmental deficits. Research on severe nausea and vomiting of pregnancy and hyperemesis gravidarum has been disturbingly slow.

Patterns of Use and Self-reported Effectiveness of Cannabis for Hyperemesis Gravidarum.

There is limited research on effective treatment of Hyperemesis Gravidarum (HG), the most extreme version of nausea and vomiting during pregnancy (NVP). This paper examines current patterns of use and self-reported effectiveness of cannabis/cannabis-based products (CBP) to treat HG. The study employed a 21-question survey to gather information on demographics, antiemetic prescription use, and experience with cannabis/CBPs among individuals who experienced extreme nausea and vomiting or HG during their pregnancy.

HyperEmesis Level Prediction (HELP Score) Identifies Patients with Indicators of Severe Disease: a Validation Study.

Hyperemesis gravidarum (HG) severity can be underestimated resulting in undertreatment and adverse outcomes. This study was conducted to validate a tool (HELP Score) designed to score HG severity. A survey link which included PUQE and HELP Score (HELP) tool questions was posted on websites related to HG.

A patient-clinician James Lind Alliance partnership to identify research priorities for hyperemesis gravidarum.

Objective: There are many uncertainties surrounding the aetiology, treatment and sequelae of hyperemesis gravidarum (HG). Prioritising research questions could reduce research waste, helping researchers and funders direct attention to those questions which most urgently need addressing. The HG priority setting partnership (PSP) was established to identify and rank the top 25 priority research questions important to both patients and clinicians.

Hyperemesis Gravidarum: Strategies to Improve Outcomes.

Hyperemesis gravidarum (HG) is a debilitating and potentially life-threatening pregnancy disease marked by weight loss, malnutrition, and dehydration attributed to unrelenting nausea and/or vomiting; HG increases the risk of adverse outcomes for the mother and child(ren). The complexity of HG affects every aspect of a woman's life during and after pregnancy. Without methodical intervention by knowledgeable and proactive clinicians, life-threatening complications may develop.

Analysis of GDF15 and IGFBP7 in Hyperemesis Gravidarum Support Causality.

Hyperemesis gravidarum, severe nausea and vomiting in pregnancy, occurs in up to 2% of pregnancies and leads to significant weight loss, dehydration, electrolyte imbalance, and ketonuria. It is associated with both maternal and fetal morbidity. Familial aggregation studies and twin studies suggest a genetic component.

Analysis of neurodevelopmental delay in children exposed in utero to hyperemesis gravidarum reveals increased reporting of autism spectrum disorder.

The purpose of this study was to follow up on the reporting of neurodevelopmental disorders in children exposed in utero to Hyperemesis Gravidarum (HG). This was an exploratory descriptive study whereby neurodevelopmental outcomes of 267 children delivered by 177 mothers with HG were compared to neurodevelopmental outcomes from 93 children delivered by 60 unaffected mothers. Similar to at age 8, the children (now 12) exposed in utero to HG had over 3-fold increase in odds of neurodevelopmental disorders including attention, anxiety, sensory, sleep difficulty, and social development delay/social anxiety.

Evidence GDF15 Plays a Role in Familial and Recurrent Hyperemesis Gravidarum.

Hyperemesis gravidarum (HG), a pregnancy complication characterized by severe nausea and vomiting in pregnancy, occurs in up to 2% of pregnancies. It is associated with both maternal and fetal morbidity. HG is highly heritable and recurs in approximately 80% of women.

Placenta and appetite genes GDF15 and IGFBP7 are associated with hyperemesis gravidarum.

Hyperemesis gravidarum (HG), severe nausea and vomiting of pregnancy, occurs in 0.3-2% of pregnancies and is associated with maternal and fetal morbidity. The cause of HG remains unknown, but familial aggregation and results of twin studies suggest that understanding the genetic contribution is essential for comprehending the disease etiology.

Genetic analysis of hyperemesis gravidarum reveals association with intracellular calcium release channel (RYR2).
