Maternal type 1collagen N-terminal telopeptide levels in severe hyperemesis gravidarum.

ABSTRACT: BACKGROUND:Nausea and vomiting occur 50-90% during the first trimester of pregnancy. However, patients with hyperemesis gravidarum (HG) may be hospitalized at an incidence rate of 0.8-2% before the 20th week of gestational age. The symptoms generally start during the 5-6th gestational weeks, reaching the highest degree during the 9th week, and decline after the 16-20th weeks of gestation. Clinical findings are proportional to the severity of the disease and severe HG is characterized with dehydration, electrolyte imbalance, and nutritional deficiency as a result of vomiting. METHODS:The study population consisted of two groups of pregnant volunteers at 5-12?weeks of gestation: a severe HG group and a control group. The HG severity was scored using the Pregnancy-Unique Quantification of Emesis (and nausea) (PUQE).The serum levels of the maternal Ca, parathyroid hormone (PTH), Na, K, blood urea nitrogen(BUN), creatinine, vitamin D(25OHD3), and the maternal urine NTx levels were compared between the groups. RESULTS:In total, 40 volunteers were enrolled in this study: 20 healthy pregnant volunteers and 20 with severe HG. There were no statistically significant differences between the maternal characteristics. The first trimester weight loss of ?5?kg was significantly higher in the severe HG group (p?

Project description:IntroductionThe pathogenesis and risk factors for hyperemesis gravidarum, excessive nausea and vomiting of pregnancy, are not adequately recognized. In our previous study, we found that women with a personal history of nausea in different situations and a family history of nausea and vomiting of pregnancy (NVP) were more likely to have severe NVP. The present study focuses on these themes in association with hyperemesis gravidarum in a hospital setting.Material and methodsWomen with hyperemesis gravidarum (n = 102) were recruited from among patients hospitalized due to hyperemesis gravidarum in Turku University Hospital, Finland. Our control group (Non-NVP group, n = 138) consisted of pregnant women with no NVP. Personal history of nausea in different situations was inquired about in relation to "motion sickness", "seasickness", "migraine", "other kind of headache", "after anesthesia", "during the use of contraception", and "other kinds of nausea". Relatives with NVP were divided into first-degree (mother and sisters) and second-degree (more distant) relatives.ResultsIn univariate analysis, a personal history of motion sickness, seasickness, nausea related to migraine, nausea with other headache and nausea in other situations were associated with hyperemesis gravidarum. After adjusting for age, parity, pre-pregnancy body mass index, marital status, and smoking, motion sickness (adjusted odds ratio [aOR] 5.24, 95% confidence interval [CI] 2.67-10.31, p < 0.0001), seasickness (aOR 4.82, 95% CI 2.32-10.03, p < 0.0001), nausea related to migraine (aOR 3.00, 95% CI 1.58-5.70, p < 0.001), and nausea in other situations (aOR 2.65, 95% CI 1.13-6.20, p = 0.025) remained significant. In multivariable analysis with all history of nausea variables, motion sickness (OR 2.76, 95% CI 1.29-5.89, p = 0.009) and nausea related to migraine (OR 3.10, 95% CI 1.40-6.86, p = 0.005) were associated with hyperemesis gravidarum. Having any affected relative (OR 3.51, 95%CI 1.84-6.73, p = 0.0002), especially a first-degree relative (OR 3.06, 95% CI 1.62-5.79, p = 0.0006), was also associated with hyperemesis gravidarum. Adjustment did not change the results.ConclusionsWomen with a personal history of nausea or a family history of NVP are more likely to suffer from hyperemesis gravidarum. These results are beneficial to better identify and help women at risk for hyperemesis gravidarum.

Project description:BackgroundInadequate maternal weight gain increases the risk of small-for-gestational age (SGA) infants. Women with hyperemesis gravidarum (HG) are at risk of significant early pregnancy weight loss and insufficient total pregnancy weight gain. Recent studies have implied that weight gain during the first half of pregnancy is more crucial to pregnancy outcome than total weight gain. The aim of this study was to investigate whether not regaining prepregnancy weight by 13-18?weeks of gestation contributed to not reaching minimum body mass index (BMI)-specific total pregnancy weight gain and influenced the risk of SGA outcome in HG pregnancies.MethodsIn this retrospective 15-year cohort (2002-2016) of women hospitalized due to hyperemesis gravidarum, we reviewed individual patient hospital files and corresponding outpatient maternity records to collect prepregnancy BMI and weight, pregnancy weight gain (spanning 3-week intervals), delivery weight and foetal outcomes. BMI and total pregnancy weight gain goals were categorized according to the Institute of Medicine (IOM) 2009 guidelines: BMI <?18,5?kg/m2: 12.5-18?kg, 18.5-24.9?kg/m2: 11.5-16?kg, 25-29.9?kg/m2: 7-11.5?kg and > 30?kg/m2: 5-9?kg. Birth weight was categorized as SGA if less than the 10th percentile of sex- and gestational length-specific Norwegian neonatal weight charts. Nonparametric tests were used to compare weight categories, and logistic regression was used to predict the odds ratio (OR) of inadequate total pregnancy weight gain or SGA delivery.ResultsOut of 892 women hospitalized for HG during 2002-2016, 784 had a pregnancy lasting >?24?weeks, of which 746 were singleton pregnancies with follow-up until delivery. Among these women, 42 were classified as underweight, 514 as normal weight, 230 as overweight and 102 as obese before pregnancy. Not regaining prepregnancy weight by week 13-18 was an independent predictor of inadequate total gestational weight gain with an OR of 7.05 (95% CI 4.24-11.71) and an independent predictor for SGA outcome with an OR of 2.66 (95% CI 1.11-6.34), even when adjusted for total pregnancy weight gain, prepregnancy BMI, parity, age and smoking status.ConclusionInadequate total maternal weight gain and not regaining prepregnancy weight by week 13-18 may be considered independent risk factors for delivering a baby that is small for gestational age in pregnancies with hyperemesis gravidarum. Achieving adequate weight gain during the first trimester in HG pregnancies is important for the foetal outcome, underscoring the importance of nutritional treatment during this period.
