Hyperemesis gravidarum, a literature review

The Effect of Hyperemesis Gravidarum on Macular Thickness, Corneal Thickness, and Intraocular Pressure in Pregnancy

AIM

Physiological changes in intraocular pressure as well as in the cornea and macula may occur during pregnancy. Therefore, we decided to investigate the effect of hyperemesis gravidarum on macular thickness, corneal thickness and intraocular pressure (IOP).

MATERIAL AND METHODS

A total of 110 people, 55 of whom were diagnosed with hyperemesis gravidarum and 55 of whom were in the control group, were included in the study. The inclusion criteria for the study were as follows: first trimester (8-14 weeks of gestation) pregnancy with positive fetal heartbeat and no history of systemic disease, no continuous use of medication, diagnosis of hyperemesis gravidarum (ketonuria and weight loss of more than 3 kilograms or 5% of body weight), body mass index (BMI) within normal limits, age between 18 and 40, no alcohol use or smoking.

RESULTS

In the HG group compared to the control group, there was a difference between the CCT values of both the right and left eyes (p<0.01). There was a difference in both right and left IOP values in patients in the HG group compared to the control group (p<0.05), and there was no correlation between ketonuria scores and right and left eye CCT values, right and left eye macular thickness, and right and left eye pressure in patients diagnosed with HG (p>0.05).

CONCLUSION

In hyperemesis gravidarum, changes occur in IOP, corneal thickness, and macular thickness. In ophthalmic examinations in the pregestational period, especially for women with systemic disease, it may be important for clinicians to take the necessary precautions in this regard.

[Hyperemesis Gravidarum - an Interprofessional and Interdisciplinary Challenge - Evidence-Based Review]

Hyperemesis gravidarum (HG) is a multifactorial disease characterized by severe and persisting nausea and vomiting, impairment of oral intake, weight loss of at least 5%, electrolyte abnormalities, and dehydration. The prevalence of HG ranges from 0.3 to 10% worldwide. The diagnosis is made by the patient's prehistory, clinical symptoms, physical examination, and the typical laboratory abnormalities. Therapeutic cornerstones are nutrition advice, consultation of life style, psychological/psychosocial support of the mother as well as the administration of antiemetics in a stepwise approach, depending on the severity of symptoms, and finally admission to hospital in severe cases. Treatment of patients requires close interprofessional and interdisciplinary cooperation.

Suicidal ideation and associated factors among pregnant women attending antenatal care at public hospitals of Harari regional state, eastern Ethiopia: A cross-sectional study

BACKGROUND

Suicide is a global issue. It is the third responsible for death among the reproductive age group. Pregnancy is a complicated event and crucial in the life of a woman with considerable physiological, hormonal changes, social, and mental changes. However, third-world countries like Ethiopia have not been investigated well. Therefore, the study planned to assess the magnitude and factors associated with suicidal ideation. Furthermore, it will identify the role of hyperemesis gravidarum on suicidal ideation.

METHOD

A Cross-sectional study was employed for 543 pregnant participants attending antenatal care at Hiwot Fana Specialized University Hospital and Jugal General Hospital, Harari regional state, eastern Ethiopia from June 1 to August 1, 2022. The recruited participants were selected by systematic random sampling method. Suicide was assessed using Composite International Diagnostic by interview methods data collection. Epi data and STATA version 14.1 were used for data entry and analysis respectively. Candidate variables were entered into a multivariate logistic regression then those variables that have p-value < 0.05 were considered as significantly associated.

RESULTS

The magnitude of suicidal ideation in this study was found to be 11.15% at (95% CI: 8.75-14.11). Regarding the associated factor, unwanted pregnancy (AOR = 3.39: at 95% CI = 1.58-7.27), Hyperemesis gravidarum (AOR = 3.65: at 95% CI = 1.81-7.34), having depressive symptoms (AOR = 2.79: at 95% CI = 1.49-5.23), having anxiety symptoms (AOR = 3.37; at 95% CI = 1.69-6.68), experiencing intimate partner violence (AOR = 2.88: at 95% CI = 1.11-7.46), and having stress (AOR = 3.46; at 95% CI = 1.75-6.86) were significantly associated variable with suicidal ideation among pregnant women.

CONCLUSION AND RECOMMENDATION

This study revealed that suicidal ideation is common among pregnant women. Regarding the associated factors unwanted pregnancy, hyperemesis gravidarum, having depressive and anxiety symptoms, experiencing intimate partner violence, and stress were significantly associated with suicidal ideation. Thus, giving awareness and early screening and interferences for antenatal suicide should be warranted.

Hyperemesis gravidarum and eating disorders before and after pregnancy: A register-based study

OBJECTIVE

Hyperemesis gravidarum (HG) is a severe form of excessive vomiting during pregnancy. The connection between psychiatric morbidity and HG has been debated, but only a few studies have focused on eating disorders (EDs). The objective of this study was to evaluate the association between HG and both pre-pregnancy and new post-pregnancy EDs.

METHODS

A register-based controlled study. HG diagnoses were retrieved from healthcare registers between 2005 and 2017. Women with HG in their first pregnancy resulting in delivery were chosen as cases (n = 4265; the HG group) and women with no HG as controls (n = 302,663; the non-HG group). The associations between EDs and HG were analyzed by binary logistic regression, adjusted with age, body mass index, smoking, socioeconomic status, and pre-pregnancy psychiatric diagnoses.

RESULTS

In the HG group, 1.6% and in the non-HG group, 0.2% had a pre-pregnancy ED. Women with ED were more likely to have HG in their first pregnancy compared with women with no history of EDs (adjusted odds ratio [AOR] 9.4, 95% CI 6.52-13.66, p < .0001). Moreover, 0.4% of the women in the HG group and 0.1% of the women in the non-HG group had a new ED diagnosis after pregnancy, and thus the women in the HG group were more likely to have an ED diagnosis after pregnancy (AOR I 3.5, 95% CI 1.71-7.15, p < .001, AOR II 2.7, 95% CI 1.30-5.69, p = .008).

DISCUSSION

We found a bidirectional association between ED and HG, suggesting a shared etiology or risk factors between these disorders. This finding emphasizes the importance of collaboration across various specialties when treating these patients.

PUBLIC SIGNIFICANCE

Our findings suggest a bidirectional association between HG and EDs before and after pregnancy. This finding provides essential information for healthcare professionals working with pregnant women. As both of these disorders are known to have far-reaching effects on the lives of both the mother and her offspring, our results help clinicians to target special attention and interventions to the patients suffering from these disorders.

Hyperemesis gravidarum and the risk of childhood cancer - A case-control study in Denmark

OBJECTIVE

Only a few studies have reported on the association between hyperemesis gravidarum and the risk of childhood cancer. We examined possible associations in this population-based study in Denmark.

METHODS

Pediatric cancer cases (n = 6420) were ascertained from the Denmark Cancer Registry among children born between 1977 and 2013. Twenty-five controls were matched to each case by sex and birth date from the Central Person Registry (n = 160500). Mothers with hyperemesis gravidarum were ascertained from the National Patient Register. The risk of childhood cancer was estimated using conditional logistic regression. In a separate analysis, we examined pregnancy prescription of antinauseant medications, ascertained from the National Pharmaceutical Register, to determine associations with childhood cancers.

RESULTS

In Denmark, hyperemesis gravidarum was associated with an increased risk of childhood cancer [all types combined; Odds Ratio (OR) = 1.43, 95% confidence interval (CI) 1.12, 1.81; n = 73 exposed cases). Hyperemesis gravidarum was also associated with an increased risk of neuroblastoma (OR = 2.52, 95% CI 1.00, 6.36; n = 5 exposed cases), acute lymphoblastic leukemia (OR = 1.63, 95% CI 0.98, 2.72; n = 16 exposed cases), and non-Hodgkin's lymphoma (OR = 2.41, 95% CI 0.95, 6.08; n = 5 exposed cases). We observed no childhood cancer risk increase from antinauseant prescriptions (OR = 1.05, 95% CI 0.84, 1.30; n = 91 exposed cases).

CONCLUSION

Our results are suggestive of an association between hyperemesis gravidarum and the overall cancer risk in offspring, particularly for neuroblastoma. Mothers with hyperemesis gravidarum should be closely monitored and receive appropriate treatment during pregnancy.

The predictive value of HALP score and systemic immune inflammation (SII) index in hyperemesis gravidarum

AIM

Hyperemesis gravidarum (HG) is one of the most common serious diseases in early pregnancy. This study aimed to investigate the clinical significance of hemoglobin, albumin, lymphocyte, and platelet (HALP) score and systemic immune inflammation (SII) index in the presence and severity of HG.

METHODS

This retrospective case-control study was conducted in a training and educational university hospital between January 2019 and July 2022. A total of 521 pregnant women, of whom 360 were diagnosed with HG at 6-14 weeks of gestation and 161 were low-risk pregnancies, were included in the study. Patients' demographic characteristics and laboratory parameters were recorded. Patients with HG were divided into three categories: mild (n = 160), moderate (n = 116), and severe (n = 84), according to disease severity. The modified PUQE scoring was used to determine the severity of HG.

RESULTS

The mean age of the patients was 27.6 (16-40) years. We divided the pregnant women into the control group and HG group. The HALP score was significantly lower in the HG group (average, 2.8 ± 1.3), whereas the SII index was found to be significantly higher (average, 895.8 ± 458.1). A negative correlation was found between the increase in the severity of HG and HALP score. The HALP score was the lower in severe HG (mean, 2.16 ± 0.81) and was significantly different from other HG categories (p < 0.01). Moreover, a positive correlation was noted between increased HG severity and SII index levels. The SII index was higher in the severe HG group and was significantly different from the others (1001.2 ± 437.2) (p < 0.01).

CONCLUSIONS

The HALP score and SII index can be useful, cost-effective, and easily accessible objective biomarkers to predict the presence and severity of HG.

The Role Of Systemic Immune-Inflammation Index In The Severity Of Hyperemesis Gravidarum

BACKGROUND

Hyperemesis gravidarum(HEG) is one of the severe health problems in early pregnancy. Obstetricians should be aware of systemic inflammation in HEG patients to provide better preventive strategies.

AIM

Hyperemesis gravidarum(HEG) is one of the most common causes of hospitalization in early pregnancy. Complete blood count parameters can be used as inflammatory markers in patients with HEG. We aimed to investigate the Systemic Immune-Inflammation Index (SII)in predicting the severity of HEG.

METHODS

This cross-sectional study was performed with 469 pregnant women diagnosed and hospitalized with HEG. The study parameters were calculated from complete blood count tests and urine analysis. Demographic characteristics, the Pregnancy Unique Quantification of Emesis (PUQE) scale values, and ketonuria levels at hospital admission were recorded. The neutrophil‑to‑lymphocyte ratio (NLR), platelet‑to‑lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and SII, calculated by the formula (neutrophil × platelet/lymphocyte), were evaluated for predicting the severity of HEG.

RESULTS

There was a positive correlation between the increased degree of ketonuria and SII. The cut-off value of SII for predicting the severity of HEG was 1071.8 (AUC 0.637, 95% CI (0.582-0.693), p<.001), and sensitivity and specificity were 59% and 59%, respectively. The cut-off value of SII to predict the length of hospitalization was 1073.6(AUC: 0.565, 95% CI: (0.501-0.628), p= 0.039); sensitivity and specificity were 56.3% and 55.5%, respectively CONCLUSIONS: : The clinical utility of SII in predicting HEG severity is limited due to relatively low sensitivity and specificity. Further research is needed to determine the importance of inflammatory indices in HEG patients.

Is hyperemesis gravidarum associated with transient hyperthyroidism? A systematic review and meta-analysis

Emerging evidence suggests an association of hyperemesis gravidarum (HG) with transient hyperthyroidism and high HCG levels. For synthesizing the current evidence to determine the association between HG with hormones related to thyroid function, a comprehensive systematic search was performed in the electronic databases comprised Medline, Web of Science, Scopus, Embase, ProQuest, and Cochrane Library up to December 2021. All published observational studies that evaluated the association of hyperemesis gravidarum with transient hyperthyroidism were investigated considering the PICO method. The standardized Joanna Briggs Institute Meta-Analysis of Statistics, Assessment, and Review Instrument were applied to appraise the included studies. Twenty-nine studies consisted of 6525 women included in the systematic review. Among them, 28 studies with 2446 participants were included in the meta-analysis. There were significant associations of HG with fT3 (MD: 1.31 pg/mL, 95% CI: 0.61 to 2.01), fT4 (MD: 1.95 ng/dL, 95% CI: 1.17 to 2.73), TSH (MD: -1.22μIU/mL, 95% CI: -1.75 to -0.68), TT4 (MD: 0.56 nmol/L, 95% CI:-0.43 to 1.24), and HCG (MD: 1.90IU/L, 95% CI: 0.497 to 3.301). In conclusion, the serum levels of fT3, fT4, and TT4 increased but TSH decreased significantly in women with compared without HG, indicating the significant association of HG with GTT.

Evaluation of Liver Disease in Pregnancy

Liver disease in pregnancy often requires diagnostic and therapeutic considerations that are unique to pregnancy. Liver disease in pregnancy is commonly thought of as either liver disease unique to pregnancy, chronic liver disease, or liver disease coincidental to pregnancy. This review summarizes the approach to evaluation of liver disease in pregnancy.

Thiamine deficiency in pregnancy and lactation: implications and present perspectives

During pregnancy, many physiologic changes occur in order to accommodate fetal growth. These changes require an increase in many of the nutritional needs to prevent long-term consequences for both mother and the offspring. One of the main vitamins that are needed throughout the pregnancy is thiamine (vitamin B1) which is a water-soluble vitamin that plays an important role in many metabolic and physiologic processes in the human body. Thiamine deficiency during pregnancy can cause can have many cardiac, neurologic, and psychological effects on the mother. It can also dispose the fetus to gastrointestinal, pulmonological, cardiac, and neurologic conditions. This paper reviews the recently published literature about thiamine and its physiologic roles, thiamine deficiency in pregnancy, its prevalence, its impact on infants and subsequent consequences in them. This review also highlights the knowledge gaps within these topics.

Maternal serum ischemia-modified albumin (IMA), total-sulphydryl concentrations, and some subclinic inflammatory markers in hyperemesis gravidarum (HG)

OBJECTIVE

This study investigates the relationship between Ischemia Modified Albumin and Total-Sulphydryl levels with some subclinical inflammatory markers in patients with hyperemesis gravidarum.

MATERIALS AND METHODS

A total of 258 pregnant women, 137 with hyperemesis gravidarum and 121 low-risk pregnancies, were included in this case-control study. The patients were divided into three groups according to the severity of hyperemesis gravidarum as mild (n = 53), moderate (n = 41) and severe (n = 43).

RESULTS

Serum Ischemia Modified Albumin levels were statistically different from the control group (P < 0.001). Among the subgroups, the highest Ischemia Modified Albumin value was observed in the severe hyperemesis gravidarum group, and the highest Total-Sulphydryl level was observed in the mild hyperemesis gravidarum group (P < 0.001). Serum potassium levels were higher in the control group (P < 0.001). While a negative correlation was observed between Ischemia Modified Albumin and Total-Sulphydryl, a positive correlation was observed in Platelet crit, C-reactive protein, and ketonuria. As the severity of the disease increases, Ischemia Modified Albumin, which is an oxidative stress factor, increases, and Total-Sulphydryl levels decrease (p < 0.001). Logistic regression analysis revealed that a one-unit increase in Ischemia Modified Albumin resulted in a statistically significant 1.9-fold increase in the risk of Severe hyperemesis gravidarum (OR 1.92, 95% CI 1.008-1.956; P = 0.01) CONCLUSION: This study shows that there is a condition in the pathophysiology of hyperemesis gravidarum, with an increase in Ischemia Modified Albumin and a decrease in Total-Sulphydryl levels, and oxidative stress occurs. It was important to detect increased Ischemia Modified Albumin and decreased antioxidant values in relation to the inflammatory factors that were effective in the severe hyperemesis gravidarum group.

Gestational malnutrition, hyperemesis gravidarum, and Wernicke's encephalopathy: What is missing?

Hyperemesis gravidarum (HG), or the severe nausea and vomiting of pregnancy, is one of the most dreaded complications of gestation, affecting between 1.5% and 3.0% of pregnant women. From the late 1800s to the mid-1980s, the etiology was frequently cited to have psychological and/or-later-perhaps hormonal origins, which have numbered at least 10. Current research has unearthed a genetic basis for HG that implicates growth differentiation factor 15, insulin-like growth factor binding protein 7, and hormone receptors (namely, glial cell line-derived neurogenic factor family receptor alpha-like and the progesterone receptor). Whatever the origins of this disease, it has caused immeasurable physiological and psychological damage to women, their fetuses, and their families. The psychological trauma includes a high rate of suicidal ideation as well as posttraumatic stress disorder. Whereas the healthcare costs are substantial for the mother with HG, the lifetime costs to the neonate include that which accompanies reduced employment earnings related to cognitive compromise. Another devastating outcome of severe HG can be Wernicke's encephalopathy (WE), which has a high fetal and maternal mortality rate. Our study explored 18 current reports of HG and WE. We highlighted additional presenting features we believe also accompany, and sometimes replace, the classically taught triad components of WE: ataxia, confabulation, and nystagmus. We agree with the conclusion made by Sheehan and Ironside in 1939 that thiamin alone may not reverse WE, and we offer possible explanations. Lastly, we offer suggestions for remediation.

Comparison of the prevalence and severity of nausea and vomiting in the first trimester between singleton pregnancies conceived from stimulated in vitro fertilization and frozen embryo transfer cycles

Objective

The objective of this prospective study is to compare the prevalence and severity of nausea and vomiting in the first trimester between singleton pregnancies conceived from stimulated in vitro fertilization (IVF) and frozen embryo transfer cycles (FET).

Methods

All women were recruited at 6 weeks gestation and filled in the modified Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) to document whether they had any experience of nausea and vomiting weekly till 12 weeks gestation. The primary outcome was the prevalence of nausea and vomiting and the secondary outcomes included severity of nausea and vomiting and pregnancy outcomes.

Results

A total of 360 pregnant women were recruited and 171 were in the stimulated IVF group and 189 in the FET group. The overall return rate was 82.2% (81.8% in the stimulated IVF group and 82.5% in the FET group). Nausea and vomiting were worse in the FET group compared with the IVF group. There were significantly more women who felt nauseated or sick in the FET group (p value = 0.032 for week 11 and p value = 0.046 for week 12); significantly more women with a longer duration of nausea in the FET group (p value = 0.044 for week 7 and p value = 0.030 for week 8); significantly more women with more vomiting in a day in the FET group (p value = 0.042) and significantly more women with retching or dry heaves in the FET group (p value = 0.030 for week 8 and p value = 0.028 for week 11).

Conclusion

Nausea and vomiting were significantly more prevalent and severe in the FET group when compared with the stimulated IVF group.

Changes in Serum Levels of Ketone Bodies and Human Chorionic Gonadotropin during Pregnancy in Relation to the Neonatal Body Shape: A Retrospective Analysis

Among the physiological changes occurring during pregnancy, the benefits of morning sickness, which is likely mediated by human chorionic gonadotropin (HCG) and induces serum ketone production, are unclear. We investigated the relationship between serum levels of ketone bodies and HCG in the first, second, and third trimesters and neonatal body shape (i.e., birth weight, length, head circumference, and chest circumference) in 245 pregnant women. Serum levels of 3-hydroxybutyric acid peaked in late-stage compared with early stage pregnancy (27.8 [5.0−821] vs. 42.2 [5.0−1420] μmol/L, median [range], p < 0.001). However, serum levels of ketone bodies and HCG did not correlate with neonatal body shape. When weight loss during pregnancy was used as an index of morning sickness, a higher pre-pregnancy body mass index was associated with greater weight loss. This study is the first to show that serum ketone body levels are maximal in the third trimester of pregnancy. As the elevation of serum ketone bodies in the third trimester is a physiological change, high serum levels of ketone bodies may be beneficial for mothers and children. One of the possible biological benefits of morning sickness is the prevention of diseases that have an increased incidence due to weight gain during pregnancy.

Hematological Parameters to Predict the Severity of Hyperemesis Gravidarum and Ketonuria

OBJECTIVE

 Hyperemesis gravidarum (HG) is a pregnancy complication that can progress with persistent nausea and vomiting. The aim of the present study is to evaluate the relationship between hematological parameters and HG.

METHOD

 A total of 532 pregnant women with HG who were admitted to the Department of Obstetrics and Gynecology between March 2019 and February 2021, and 534 healthy pregnant women with characteristics similar to those of the case group were included in the study. The hematological parameters of both groups were compared. In addition, the hematological parametersof patients with HG according to the severity of ketonuria were compared.

RESULTS

 The mean age of the HG group (n = 532) was 26.3 ±  4.1 years, and that of the control group (n = 534) was 25.9 ±  4.8 years. Among patients with HG, 46% (n = 249) had ketone (+), 33% (n = 174), ketone (++), and 21% (n = 109), ketone (++ + ). The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were higher in the HG group than in the control group: 3.8 (2.8-5.8)/3.2 (2.6-4.0); p < 0.001; and 135.2 ±  30.4/108.9 ±  62.2; p < 0.001 respectively. The neutrophil count, NLR, and PLR were higher in the group with ketone (++ + ) than in the groups with ketone (+) or ketone (++): 7.6 ±  1.9/5.5 ±  2.4; p < 0.001; 3.8(2.8-4.6)/2.9(2.3-3.6); p < 0.001; and 149.9 ±  48.0/135.9 ±  65.7; p < 0.001 respectively. The mean corpuscular hemoglobin (MCH) level, the NLR, and the PLR were identified as independent predictors of the presence of HG and the level of ketone positivity in HG patients.

CONCLUSION

 The NLR and PLR were high in patients with HG, suggesting the its inflammatory activity. They may be important markers associated with the presence and severity of HG.

Chronic nausea and vomiting: a diagnostic approach

INTRODUCTION

Chronic nausea and vomiting (CNV) are commonly encountered symptoms in medical practice. CNV is the presenting symptom in a variety of gastrointestinal and non-gastrointestinal disorders. However, in a significant percentage of patients without an obvious underlying cause, CNV poses a significant diagnostic challenge to the evaluating physician.

AREAS COVERED

A comprehensive clinical history and physical examination form the foundation for further diagnostic work-up. In the present review, we discuss the diagnostic approach to CNV, highlighting the epidemiology, pathophysiology, causes, and modes of evaluation of this condition. Specific investigations, carefully guided by clinical assessment and tailored for each patient, would be more beneficial in diagnosing CNV than empirically performing a blanket of investigations.

EXPERT OPINION

Whilst CNV remains a historically challenging diagnostic and therapeutic dilemma, research into this topic is limited. Hence, there is a growing call for more research into diagnostic modalities for CNV. With scientific advancement and further research, it is hoped that easy-to-use, cheap, noninvasive novel diagnostic modalities for CNV will be available soon.

Efficacy of group biofeedback treatment on hyperemesis gravidarum with psychosomatic symptoms diagnosed with the revised version of Diagnostic Criteria for Psychosomatic Research (DCPR-R): study protocol for a randomised controlled trial

INTRODUCTION

Hyperemesis gravidarum (HG) is a condition characterised by dehydration, electrolyte imbalance, lack of nutrition and at least 5% loss in body weight, occurring in the first half of pregnancy. The aim of this trial is to examine the efficacy of group biofeedback treatment on patients with HG with psychosomatic symptoms, which will be evaluated through the revised version of Diagnostic Criteria for Psychosomatic Research (DCPR-R).

METHODS AND ANALYSIS

In this single-blinded randomised controlled clinical trial, 68 patients with HG diagnosed with at least one psychosomatic syndrome according to DCPR-R and aged 18-40 years, will be recruited in a Chinese Maternal and Child Health Hospital. The sample will be randomised (1:1) into two arms: experimental group, which will undergo group biofeedback treatment, psycho-education and treatment as usual (TAU); and control group, which will undergo psycho-education and TAU only. The primary outcomes will be reduction of the frequency of psychosomatic syndromes, severity of nausea/vomiting, quality of life and heart rate variability. The secondary outcomes will include days of hospitalisation, repeated hospitalisation and laboratory investigations.

ETHICS AND DISSEMINATION

This study has received ethical approval from the Nanjing Medical University (No. 2019/491, granted 22 February 2019). All participants will be required to provide written informed consent. Study outcomes will be disseminated through peer-reviewed publications and academic conferences, and used to confirm a tailored biofeedback intervention for patients with HG with psychosomatic symptoms.

TRIAL REGISTRATION NUMBER

Chinese Clinical Trial Registry (ChiCTR2000028754).

Anti-Mullerian hormone levels in spontaneous pregnancies with hyperemesis gravidarum

We investigated the serum anti-Mullerian hormone (AMH), oestrogen and progesterone levels in spontaneously conceiving pregnant women, diagnosed for hyperemesis gravidarum (HG), in the first trimester. Pregnant women admitted at Hospital between 5 and 12 gestational weeks and treated for HG were compared, in this prospective case-control study, to a control group. The serum AMH, oestradiol, and progesterone values of both groups were evaluated and compared, and potential correlations were calculated. The serum AMH values were significantly higher in the HG group than the control group (3.15 ± 1.51 ng/mL vs. 2.27 ± 1.20 ng/mL; p = 0.012). No significant difference in the two groups was about serum oestradiol and progesterone values (p = 0.264, p = 0.235). In the HG group, there was no significant correlation between AMH and oestradiol (p = 0.570). However, a significant positive correlation was determined between AMH and progesterone (p = 0.050). The area under the ROC curve (AUC) was 0.669 and the cut-off value was 2.65 ng/ml with sensitivity of 58.3% and specificity of 66.7% for AMH in pregnant women with HG. A correlation between AMH high values and unexplained HG was detected in spontaneous pregnancies in the first trimester. High AMH levels may play a role in HG etiopathogenesis, especially in pregnant women with low progesterone levels.Impact statementWhat is already known on this subject? Aetiological causes of Hyperemesis gravidarum (HG) include hormonal, immunological, genetic, and psychological issues. However, no conclusive etiopathogenesis to explain the pathophysiological mechanism of HG has been stated.What do the results of this study add? Authors focussed on investigation a possible correlation between pregnant hormones and the HG pathogenesis, prevalent in the first trimester, when hormones are produced by either the placenta or corpus luteum. High anti-Mullerian hormone (AMH) levels may play a role in HG etiopathogenesis, especially in pregnant women with low progesterone levels.What are the implications of these findings for clinical practice and/or further research? A serum AMH level of ≥2.65 mg/mL could be predictive for the development of HG in the first trimester of a spontaneous pregnancy. Basing on these findings, more selective pharmacological treatments could be administrated to these patients.

Pr-AKI: Acute Kidney Injury in Pregnancy – Etiology, Diagnostic Workup, Management

Despite significant improvements in inpatient and outpatient management, pregnancy-related acute kidney injury (Pr-AKI) remains an important risk factor for early and late maternal and fetal morbidity and mortality. There is a discrepancy between the incidence of Pr-AKI in developing and in developed countries, with the former experiencing a decrease and the latter an increase in Pr-AKI in recent decades. Whereas septic and hemorrhagic complications predominated in the past, nowadays hypertensive disorders and thrombotic microangiopathy are the leading causes of Pr-AKI. Modern lifestyles and the availability and widespread use of in-vitro fertilization techniques in industrialized countries have allowed more women of advanced age to become pregnant. This has led to a rise in the percentage of high-risk pregnancies due to the disorders and comorbidities inherent to or accompanying aging, such as diabetes, arterial hypertension and preexisting chronic kidney disease. Last but not least, the heterogeneity of symptoms, the often overlapping clinical and laboratory characteristics and the pathophysiological changes related to pregnancy make the diagnosis and management of Pr-AKI a difficult and challenging task for the treating physician. In addition to general supportive management strategies such as volume substitution, blood pressure control, prevention of seizures or immediate delivery, each disease entity requires a specific therapy to reduce maternal and fetal complications. In this review, we used the current literature to provide a summary of the physiologic and pathophysiologic changes in renal physiology which occur during pregnancy. In the second part, we present common and rare disorders which lead to Pr-AKI and provide an overview of the available treatment options.

Anxiety, depression and marital satisfaction in women with hyperemesis gravidarum: A comparative cross-sectional study in Hospital Tengku Ampuan Rahimah, Klang, Malaysia

INTRODUCTION

Hyperemesis Gravidarum (HG) is a severe form of vomiting that occurs among pregnant mothers. Due to the nature of HG, pregnant mothers may feel fatigued and burdened by it and questions have been raised about the emergence of psychiatric illness during this period of vulnerability.

METHODS

A comparative cross-sectional study using Hospital Anxiety and Depression Scale (HADS), M.I.N.I (MINI International Neuropsychiatric Interview) and ENRICH- EMS (Evaluation and Nurturing Relationship Issues, Communication and Happiness - Marital Satisfaction Scale) were performed in a group of 112 pregnant women.

RESULTS

There were no differences in the prevalence rate of any anxiety disorder among the patient with HG vs comparative group (9% vs 3%, P > 0.05) and depressive disorder in women with HG vs comparative group (16% vs 8%, P > 0.05) respectively. There were associations between HG and gravida, past history of miscarriage, and gestational diabetes (P < 0.05). After adjustment, only past history of gestational diabetes was associated with HG as a protective factor (AOR 0.034 95% CI 0.002-0.181; P = 0.0014). We found that women in the HG group tended to score statistically significantly higher than the comparison group for depressive symptoms in the HADS Depression subscale (P = 0.041).

DISCUSSION

We found no convincing association between HG and anxiety disorder, depressive disorder, and marital satisfaction, but women with HG statistically significantly reported more depressive symptoms than women who were not diagnosed with HG. Psychiatric evaluation should be considered for women with HG.

Emerging Progress in Nausea and Vomiting of Pregnancy and Hyperemesis Gravidarum: Challenges and Opportunities

Nausea and vomiting of pregnancy (NVP) is a common condition that affects up to 70% of pregnant women. Hyperemesis gravidarum (HG) is considered the serious form of NVP, which is reported in 0.3–10.8% of pregnant women. NVP has a relatively benign course, but HG can be linked with some poor maternal, fetal, and offspring outcomes. The exact causes of NVP and HG are unknown, but various factors have been hypothesized to be associated with pathogenesis. With the advance of precision medicine and molecular biology, some genetic factors such as growth/differentiation factor 15 (GDF15) have become therapeutic targets. In our review, we summarize the historical hypotheses of the pathogenesis of NVP and HG including hormonal factors, Helicobacter pylori, gastrointestinal dysmotility, placenta-related factors, psychosocial factors, and new factors identified by genetics. We also highlight some approaches to the management of NVP and HG, including pharmacological treatment, complementary treatment, and some supporting treatments. Looking to the future, progress in understanding NVP and HG may reduce the adverse outcomes and improve the maternal quality of life during pregnancy.

Effects of Bilwa-Lajadi syrup in emesis gravidarum - an exploratory single arm open labeled trial

Background

Emesis gravidarum is a common obstetrical problem affecting 50–80% of pregnant women during their first trimester which begins in the morning and frequently continues throughout the day; considered as one of the Vyakta Garbha Lakshana in Ayurveda. If it is not treated effectively in time; it may lead to complications in pregnancy affecting the quality of life and thus the pregnancy outcome.

Objective

To evaluate the clinical effectiveness of Bilwa-Lajadi syrup in emesis gravidarum.

Material and methods

A single arm open labeled clinical trial was conducted on 30 participants fulfilling the inclusion criteria from OPD and IPD of Prasuti Tantra Evam StreeRoga, Sri Dharmasthala Manjunatheshwara College of Ayurveda and Hospital, Hassan and administered with Bilwa-Lajadi Syrup 20 ml per day in two divided doses, empty stomach before food for 30 days with followed up every 15 days during treatment and 15 days after completion of trial period.

Results

The drug showed statistically significant effect in reducing the frequency of vomiting per day, quantity of vomitus, aversion to smell, nausea and anorexia, altered content of vomitus, improved appetite, imparted lightness of body and increased haemoglobin gm%.

Conclusion

Thus, early medication with Bilwa-Lajadi syrup and following dietetic regimen played a vital role in relieving the symptoms of emesis gravidarum.

Hyperemesis gravidarum in the primary care setting: cross-sectional study of GPs

BACKGROUND

Hyperemesis gravidarum (HG), if untreated, can lead to malnutrition, dehydration, and Wernicke's encephalopathy. Foetal complications include low birth weight and neurodevelopmental delay. Recent evidence supports increased rates of termination of pregnancy and suicidal ideation. Drivers included difficulty in accessing medications, which thus contributed to poor perception of care.

AIM

To identify factors that may influence prescribers' confidence and knowledge regarding pharmacological therapy for HG.

DESIGN & SETTING

Cross-sectional study of qualified GPs and GP trainees in Wales.

METHOD

Distribution of a 22-item online survey. Statistical analysis was carried out using SPSS.

RESULTS

In total, 241 responses were received, with 216 included in the analysis (59% qualified GPs, 41% GP trainees). In total, 93% of responders correctly identified cyclizine as being safe in pregnancy, but no other drug recommended in the Royal College of Obstetrics and Gynaecology guidance was considered safe by more than 58%. Those reporting higher confidence levels in managing HG were more likely to correctly report guideline-recommended drugs as safe in pregnancy (P = 0.04). Additional qualifications related to obstetrics and gynaecology (O&G) and/or prior clinical experience increased confidence levels (P = 0.0001 and P = 0.0002, respectively). Only 19% of participants routinely screened for signs of mental health complications, and prior experience or education did not increase likelihood of this happening. The majority of participants (87%) would like additional education and/or access to evidence-based resources.

CONCLUSION

This study demonstrates a demand for improved dissemination of evidence-based education on HG to support those working in primary care. The extent to which HG is covered in pre-existing educational programmes should also be revisited.

Nausea During Pregnancy and Timing of Pubertal Development in Sons and Daughters: A Population-Based Cohort Study

PURPOSE

The objective of this study was to explore whether maternal nausea in pregnancy, a potential surrogate marker of endogenous estrogen levels, was associated with age at attaining pubertal milestones in sons and daughters.

MATERIALS AND METHODS

The study included a total of 14,612 boys and girls born in 2000-2003, from the Danish National Birth Cohort. Information on nausea was reported by mothers during pregnancy in telephone interviews scheduled around gestational week 12 and 30. Their children were invited every six months from 11 years of age until 18 years of full maturation to provide information on current pubertal status. Pubertal milestones included pubic hair, axillary hair and acne for both sexes, besides genital development, voice break and first ejaculation for boys, and breast development and menarche for girls. Mean monthly differences in age at attaining several pubertal milestones for boys and girls were estimated according to duration of nausea in the first trimester (0, 1-6, 7-11, 12 weeks). Further, we explored whether duration of nausea in the first two trimesters (0, 1-8, 9-15 or 16-28 weeks) and severity (measured by co-existence of vomiting and weight loss) were associated with pubertal timing.

RESULTS

Neither maternal nausea in the first trimester nor duration or severity of nausea in the first two trimesters were associated with pubertal timing.

CONCLUSION

Our study does not support the hypothesis that nausea in pregnancy - as a surrogate marker of endogenous estrogen levels - is associated with age at attaining pubertal milestones in children.

A pregnant woman who experienced auditory hallucinations concurrent with hyperemesis gravidarum: A case report

We report the case of a pregnant woman who experienced auditory hallucinations only while suffering from hyperemesis gravidarum. To the best of our knowledge, the present report is the first report of a case of obvious auditory hallucinations and hyperemesis gravidarum at the same time in a pregnant woman who had not been diagnosed with any psychiatric disorder. The patient was a 24‐year‐old pregnant woman with no history of psychiatric disorder. Two years prior to this admission, she became pregnant for the first time, and she was admitted to an obstetrics clinic due to severe hyperemesis gravidarum. She developed mild auditory hallucinations at the same time. After she gave birth, the auditory hallucinations disappeared. When she was 24 years old, she became pregnant again. She suffered from severe hyperemesis gravidarum from the early stage of pregnancy. At 20 weeks of pregnancy, she visited the Department of Psychiatry of our hospital for a detailed psychiatric evaluation and treatment because her moderate auditory hallucinations had relapsed. We administered an antipsychotic agent, perospirone, to treat the auditory hallucinations, which disappeared, although the hyperemesis gravidarum persisted until childbirth. After childbirth, perospirone treatment was discontinued, and her auditory hallucinations did not relapse. The auditory hallucinations may have occurred as a result of complicated biological and psychosocial factors. Physicians should carefully evaluate psychotic symptoms, such as auditory hallucinations, not only during the postpartum period but also throughout the course of pregnancy.

Liver and Biliary Disease of Pregnancy and Anesthetic Implications: A Review

Liver and biliary disease complicates pregnancy in varying degrees of severity to the mother and fetus, and anesthesiologists may be asked to assist in caring for these patients before, during, and after birth of the fetus. Therefore, it is important to be familiar with how different liver diseases impact the pregnancy state. In addition, knowing symptoms, signs, and laboratory markers in the context of a pregnant patient will lead to faster diagnosis and treatment of such patients. This review article discusses changes in physiology of parturients, patients with liver disease, and parturients with liver disease. Next, general treatment of parturients with acute and chronic liver dysfunction is presented. The article progresses to specific liver diseases with treatments as they relate to pregnancy. And finally, important aspects to consider when anesthetizing parturients with liver disease are discussed.

Effectiveness of Acupuncture in the Treatment of Hyperemesis Gravidarum: A Systematic Review and Meta-Analysis

Background

Hyperemesis gravidarum (HG) is a common gastrointestinal disease afflicting gravidas. It usually results in hospital admission in early pregnancy.

Objective

Through a meta-analysis, this study intended to explore acupuncture's clinical efficacy in treating HG.

Materials and Methods

A comprehensive search of PubMed, the Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biological Medical (CBM), Wanfang Database, and China Science and Technology Journal (VIP) for published clinical randomized controlled trials (RCTs) of acupuncture for treating HG was conducted from the date of database creation to 20th January 2021. We also searched grey literature in four databases: Chinese Cochrane Center, Chinese Clinical Trial Registry, GreyNet International, and Open Grey from their inception to 20th January 2021. Two authors independently screened the literature, extracted data, and evaluated the quality of the literature with Cochrane Handbook 5.1.0 and Review Manager 5.2 software. Review Manager 5.2 and STATA 12.0 software were applied to analyze data. Heterogeneity analysis was performed by the Cochran Chi-square test and I ² statistic. Egger's tests together with funnel plots were used to identify publication bias.

Results

A total of 16 trials covering 1043 gravidas were included. Compared with the conventional treatment, acupuncture had a significantly higher effective rate (OR: 8.11, 95% CI: 5.29∼12.43; P < 0.00001), a higher conversion rate of urine ketone (RR: 1.36, 95% CI: 1.15∼1.60; P=0.0003), an improvement rate of nausea and vomiting (OR: 26.44, 95% CI: 3.54∼197.31; P=0.001), and a relatively higher improvement rate of food intake (RR: 1.17, 95% CI: 1.01∼1.36; P=0.04). Acupuncture also shortened hospitalization time and manifested with a lower pregnancy termination rate and fewer adverse events. Nevertheless, no statistical variation in the improvement of nausea intensity, vomiting episodes, and lassitude symptom, recurrence rate, and serum potassium was observed.

Conclusion

Our study suggested that acupuncture was effective in treating HG. However, as the potential inferior quality and underlying publication bias were found in the included studies, there is a need for more superior-quality RCTs to examine their effectiveness and safety. PROSPERO registration number: CRD42021232187.

Wernicke's encephalopathy in women with hyperemesis gravidarum - Case series and literature review

Whilst nausea affects around 80% of pregnant women, hyperemesis gravidarum, an extreme form of the same, affects only 0.5% to 3%, but may lead to severe nutritional deficiency. Wernicke's encephalopathy is an acute neuropsychiatric disorder which occurs due to thiamine deficiency and needs emergency treatment to prevent neurological morbidity and mortality. Wernicke's encephalopathy is characterised by a clinical triad of oculomotor abnormalities, cerebellar dysfunction and altered mental state. Korsakoff's psychosis is a chronic condition and consequence of Wernicke's encephalopathy, resulting from its delayed treatment. Wernicke's encephalopathy is a well-known complication of chronic alcohol abuse. Not many are aware of its association with hyperemesis gravidarum. Although it is a rare complication, if not diagnosed and treated promptly, it may result in permanent and irreversible neurological sequelae. The objective of our retrospective observational study was to analyse the clinical profile and outcome (short and long term) in a rare yet preventable complication of pregnancy.

The relationship between inflammation markers and ketonuria in hyperemesis gravidarum

OBJECTIVE

Hyperemesis gravidarum is an illness that starts in early pregnancy and manifests itself with oral intake problems, electrolyte imbalance, ketonuria, and weight loss. Inflammation is closely associated with the hyperemesis gravidarum, and inflammatory indicators have been studied to understand its pathophysiology. This study investigates the relationship of ketonuria levels with inflammatory markers platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and neutrophil-to-lymphocyte ratio (NLR) for hyperemesis gravidarum patients.

MATERIAL AND METHODS

This retrospective case control study was conducted at Kütahya Medical Sciences University Tertiary Research and Training Hospital between December 2019 and December 2020. A total of 173 pregnancies, 82 of them with hyperemesis gravidarum and 91 of them low-risk pregnancies were included in the study. The patients' demographic profiles and laboratory parameters were recorded. The patients were divided into hyperemesis gravidarum and control groups and the groups were compared for the levels of inflammation markers. For the hyperemesis gravidarum group, the relationship between ketonuria levels and the inflammation severity was investigated.

RESULTS

MLR, NLR, PLR levels were higher in the hyperemesis gravidarum group than the control group in a statistically significant way (p < 0.001 for all of the comparisons). The hyperemesis gravidarum group was subdivided into four groups based on their ketonuria levels, and their MLR, NLR, PLR levels were compared. The differences between the groups were statistically significant (p < 0.001) and the indicators increased with the ketonuria levels. Finally, ketonuria levels had a positive and significant correlation with MLR (rho =0.67, p < 0.001), PLR (rho =0.67, p < 0.001), and NLR (rho =0.8, p < 0.001).

CONCLUSION

Hyperemesis gravidarum patients have higher levels of hematologic inflammation indicators than healthy pregnant patients. For these patients, the levels of the indicators increase with ketonuria levels.

Evaluation of psychological resilience and anxiety levels of patients with hyperemesis gravidarum diagnosis and comparison with healthy pregnant women

Objective:

To compare the psychological resilience and anxiety levels of patients diagnosed with hyperemesis gravidarum (HG) and healthy pregnant women.

Materials and Methods:

A sociodemographic data form and the Resilience scale for Adults (RSA) and the State-Trait Anxiety Inventory (STAI) were administered. The sociodemographic data form was completed by the physician, and the RSA and STAI were completed by the participant. The sample of the study consisted of 60 pregnant women with HG and hospitalized and 97 healthy voluntary pregnant women with similar characteristics to the research group without any pregnancy complications. Data were evaluated using descriptive statistical analyses, the independent samples t-test, the Mann-Whitney U test and Pearson’s correlation analysis.

Results:

The age range was 18-42 years for HG group and 20-43 years for control group. The average age of the HG group was 28.17±5.96 years and that of the control group was 29.45±5.83 years. There was no statistically significant difference between the groups in terms of pregnancy week. Regarding the prevalence of state and trait anxiety between the groups, it was found that 66.7% of the HG group had a high level of trait anxiety and 51.7% had a high level of state anxiety. It was found that 61.9% of the control group had a high level of trait anxiety and 38.1% had a high level of state anxiety. There was no difference between the healthy pregnant group and the HG group in terms of anxiety (p=0.125). It was found that there was a significant difference between the groups in terms of only sub-dimensions of RSA, which were perception of self (U=2385.00, p=0.044) and perception of future (U=2350.50, p=0.030). The perception of self and perception of future scores of the healthy control group were higher.

Conclusion:

There was no difference between the healthy pregnant group and the HG group in terms of anxiety. It was observed that the HG group had a lower perception of self and future. Apart from the usual increase in anxiety levels during pregnancy, HG accompanied by stubborn nausea and vomiting does not create an extra psychological burden, either as a cause or a result.

Ginger candy (Zingiber officinale) reduces the frequency of vomiting of first-trimester pregnant women with emesis gravidarum

OBJECTIVE

This study aimed to determine the effectiveness of ginger candy to reduce the frequency of vomiting in trimester pregnant women.

METHODS

It was a quasi-experimental study with non-randomized pre-test post-test with control group. The subject was divided into three groups of interventions, i.e. ginger candy, placebo, administering vitamin B6. The samples were 51 the first-trimester pregnant mothers that experience the emesis or vomit 3-5times/day, each group consist of 17 pregnant mothers. Intervention was done as long as 7 days.

RESULTS

Data shows that before giving the intervention, all groups experienced vomiting 3-5times/day, i.e. 17 people (100%). There was no difference between the ginger candy, placebo and vitamin B6 groups, but after giving the intervention, there were differences in the frequency of vomiting, the remaining ginger candy groups were 4 people (23.6%) who had a frequency of vomiting 3-5 times/day, while in the group given vitamin B6 there are still 16 people (94.1%). The group was given placebo all subjects, namely, 17 people (100%) still experienced vomiting 5-3 times/day.

CONCLUSION

Ginger candy can reduce the frequency of vomiting in pregnant women with emesis gravidarum.

Mode of conception in relation to nausea and vomiting of pregnancy: a nested matched cohort study in Sweden

Nausea and vomiting of pregnancy (NVP) is a common condition reported however inconclusively among pregnancies after assisted conception. The study objective was thus to explore whether NVP is associated to mode of conception or other in vitro fertilization (IVF)-related variables. This nested matched cohort study, originating from the BASIC-project, was conducted at the Uppsala University Hospital in Sweden between 2010 and 2016. IVF pregnancies (n = 210) and age and parity-matched women with spontaneous pregnancies (n = 420) comprised the study sample. The study outcome was self-reported NVP at gestational week 17. IVF treatment and pregnancy data were obtained after scrutinization of the medical records. NVP with or without medications was not associated with mode of conception (chi-square test, p = 0.889), even after adjusting for potential confounders. In a subgroup analysis among IVF pregnancies, NVP without medication was more frequently seen in the group who received cleavage stage embryos vs blastocysts (chi-square test, p = 0.019), exhibiting a marginally significant but strongly increased effect even after adjustment [crude RRR 3.82 (95% CI 1.23–11.92) and adjusted RRR 3.42 (95% CI 0.96–12.11)]. No difference in the rate of NVP with or without medication between women that underwent fresh and frozen/thawed embryo transfers as well as IVF or ICSI was observed. Conception through IVF is not associated with NVP. Transfer of a blastocyst may decrease the risk of developing NVP and further, large-scale prospective studies are required to validate this finding.

What stops us from eating: a qualitative investigation of dietary barriers during pregnancy in Punjab, Pakistan

OBJECTIVE

Adequate dietary intake during pregnancy is vital for the health and nutritional status of both mother and fetus. The nutritional status of reproductive age women in Pakistan is poor, with 14 % being underweight (BMI < 18·5) and 42 % experiencing Fe deficiency anaemia. This may stem from beliefs, practices and other barriers influencing dietary intake. This qualitative study seeks to determine which factors impact dietary intake during pregnancy in rural Punjab.

DESIGN

In-depth interviews and focus group discussions were conducted and then analysed using thematic analysis.

SETTING

Three purposively selected rural districts (Sahiwal, Okara and Pakpatan) with the highest prevalence of maternal and child malnutrition in the province of Punjab, Pakistan.

PARTICIPANTS

Mothers with children under age two (n 29) and healthcare providers with at least 5 years of experience working in the district (n 12).

RESULTS

We identified a combination of physiological, socio-cultural and structural barriers that inhibited healthful dietary intake during pregnancy. The primary physiological barriers to optimal dietary intake and dietary practices included food aversions and food cravings. Food classification, fear of a difficult childbirth, fear of high blood pressure and household food politics were the principal socio-cultural barriers. Additionally, two structural barriers, inadequate antenatal counseling and a lack of affordable food options, were identified.

CONCLUSIONS

Our study demonstrates that complex barriers prevent pregnant women in the Punjab area from consuming adequate dietary intake and that antenatal health education programmes and structural interventions are needed to support healthful dietary practices during this critical period.

Original article: is the protective association between hyperemesis gravidarum and birth defects biased by pregnancy termination?

PURPOSE

We assessed whether the protective association between hyperemesis gravidarum and birth defects could be due to selection bias from exclusion of pregnancy terminations.

METHODS

We designed a cohort study of 2,115,581 live births in Canada, 1990-2016. The main exposure measure was hyperemesis gravidarum. The main outcome measure included any birth defect at delivery. We estimated risk ratios (RR) and 95% confidence intervals (CI) for the association of hyperemesis gravidarum with birth defects in log-binomial regression models, and assessed the extent of selection bias through correction factors.

RESULTS

Hyperemesis gravidarum was associated with 0.88 times the risk of birth defects in models not corrected for bias (95% CI 0.82-0.94). Correction for selection bias suggested that if screening for birth defects was associated with 1.33 times the chance of detecting birth defects and having a pregnancy termination, there would be no association with hyperemesis gravidarum. If ultrasound was associated with 2.00 times the chance of detecting birth defects and 1.50 times the risk of pregnancy termination, hyperemesis gravidarum would be associated with 1.27 times the risk of birth defects (95% CI 1.18-1.35).

CONCLUSIONS

The protective association between hyperemesis gravidarum and birth defects in previous studies may be due to selection bias.

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. Effectively managing HG requires an understanding of both physical and psychosocial stressors, recognition of potential risks and complications, and proactive assessment and treatment strategies using innovative clinical tools.

Severity of nausea and vomiting in pregnancy and early childhood neurobehavioural outcomes: The Growing Up in Singapore Towards Healthy Outcomes study

BACKGROUND

Nausea and vomiting of pregnancy (NVP) affects 50 to 80 per cent of women. The existing literature has examined NVP from the perspective of the mother, and relatively less is known about offspring outcomes.

OBJECTIVES

To study the relationships of NVP with social-emotional, behavioural, and cognitive outcomes of the offspring in a multi-ethnic Asian cohort.

METHODS

In the Growing Up in Singapore Towards Healthy Outcomes prospective mother-offspring cohort study, mothers responded to a structured NVP questionnaire at 26-28 weeks' gestation (n = 1172) and participants with severe NVP were confirmed using medical records. Children underwent multiple neurodevelopmental assessments throughout childhood. We conducted multivariable regressions with post-estimation predictive margins to understand the associations of NVP with offspring neurobehavioural outcomes, which included 1-year Infant-Toddler Social and Emotional Assessment, 1.5-year Quantitative Checklist for Autism in Toddlers, 2-year Bayley Scales of Infant and Toddler Development, 2- and 4-year Child Behavior Checklist, and 4.5-year Kaufman Brief Intelligence Test. Analyses were adjusted for household income, birth variables, maternal mental health, and other relevant medical variables. Cohen's d effect sizes were calculated using standardised mean differences (μ_d ).

RESULTS

Mothers were categorised into no (n = 296, 25.3%), mild-moderate (n = 686, 58.5%), and severe NVP (n = 190, 16.2%), of whom 67 (5.7%) required admission. Compared to children of mothers who had no or mild-moderate NVP, children with exposure to severe NVP exhibited more externalising behaviours (μ_d 2.0, 95% CI 0.3, 3.6; Cohen's d = 0.33) and social communication difficulties before 2 years (μ_d 4.1, 95% Cl 0.1, 8.0; Cohen's d = 0.38), both externalising (μ_d 1.5, 95% CI 0.4, 2.6; Cohen's d = 0.43) and internalising behaviours at 2 years (μ_d 1.2, 95% CI 0.1, 2.2; Cohen's d = 0.35), and only internalising behaviours after 2 years (μ_d 1.1, 95% CI 0.4, 2.0; Cohen's d = 0.37).

CONCLUSIONS

Severe NVP is highly prevalent in this Asian cohort and may be adversely associated with multiple offspring neurobehavioural outcomes.

Pre-Pregnancy Risk Factors for Severe Hyperemesis Gravidarum: Korean Population Based Cohort Study

Hyperemesis gravidarum is known to be associated with poor perinatal outcomes. This study aimed to identify pre-pregnancy risk factors for hospital admission in women with hyperemesis gravidarum. We enrolled women who had delivered between 1 January 2013 and 31 December 2015, and had undergone a national health screening examination through the National Health Insurance Corporation 1-2 years before their first delivery. Multiple logistic regression analysis was performed to estimate the risk factors for hospital admission due to hyperemesis gravidarum. Of the 216,373 study participants with hyperemesis gravidarum, 2210 (1.02%) pregnant women were hospitalized. These women had lower waist circumference and were underweight based on body mass index compared to pregnant women who did not require hospitalization due to hyperemesis gravidarum. On multivariate analysis, primiparity, multiple pregnancies, female fetus, alcohol consumption, and pre-pregnancy underweight status were associated with an increased risk of hospitalization due to the condition. In this population-based cohort study, we found that hospitalization due to hyperemesis gravidarum was associated with pre-pregnancy lifestyle characteristics. Early recognition and management of these pre-pregnancy factors may help control the need for hospitalization in women with the condition in subsequent pregnancies.

Percutaneous Endoscopic Jejunostomy Tube Placement for Treatment of Severe Hyperemesis Gravidarum in Pregnancy

Hyperemesis gravidarum is a common disease. Most patients are effectively treated with conservative measures, but gastric feeding and, rarely, post-pyloric feeding can be necessary. A 27-year-old woman, G3P2002, with a history of refractory hyperemesis in previous pregnancies, required placement of a nasojejunal tube but was removed due to an oropharyngeal ulcer. Endoscopic placement of a percutaneous endoscopic transgastric-jejunostomy (PEG-J) tube caused resolution of her symptoms. Twelve days after placement, the distal tube became dislodged and was endoscopically replaced with hemoclip anchoring in the jejunum. PEG-J tube placement is a safe and effective option for nutritional support in refractory hyperemesis gravidarum.

Management Considerations for Recalcitrant Hyperemesis

Importance

Hyperemesis gravidarum (HEG) affects 0.3% to 3% of pregnancies and requires additional therapies beyond those commonly used for less severe instances of nausea and vomiting of pregnancy (NVP). Differentiating between NVP and HEG is a vital yet challenging function for any obstetrician. The literature for management of HEG is lacking compared with that of NVP.

Objective

Review etiology of NVP/HEG highlights key considerations in the workup of HEG as they compare to NVP and explore management options for recalcitrant HEG focusing principally on how they affect maternal and fetal outcomes and secondarily on where data are nonprescriptive.

Evidence Acquisition

This was a literature review primarily using PubMed and Google Scholar.

Results

Short-course corticosteroids and treatment for Helicobacter pylori have the most favorable risk-reward profiles of the 4 pharmacologic therapies evaluated. Mirtazapine and diazepam may have a place in highly selected patients. If nutritional supplementation is required, enteral nutrition is strictly preferred to parenteral nutrition. Postpyloric feeding approaches are less likely to induce vomiting. Surgically placed feeding tubes are less likely to be dislodged and may be worth the invasive insertion procedure if nasogastric or nasojejunal tubes are not tolerated.

Conclusions and Relevance

Hyperemesis gravidarum is a diagnosis reserved for refractory cases of NVP and therefore by definition poses treatment challenges. Any clinical presentation that lent itself to prescriptive, algorithmic management would likely fall short of the diagnostic criteria for HEG. However, data can inform management on a patient-by-patient basis or at least help patient and provider understand risks and benefits of therapies reserved for refractory cases.

Association between hyperemesis gravidarum and psychological symptoms, psychosocial outcomes and infant bonding: a two-point prospective case-control multicentre survey study in an inner city setting

OBJECTIVES

To assess if there is any association between hyperemesis gravidarum (HG), psychological morbidity and infant bonding and to quantify any psychosocial consequences of HG.

DESIGN

Two-point prospective case-control, multicentre survey study with antenatal and postnatal data collection.

SETTING

Three London hospitals.

PARTICIPANTS

Pregnant women at ≤12 completed weeks gestation recruited consecutively over 2 years. Women with HG were recruited at the time of admission; controls recruited from a low risk antenatal clinic. 106 women were recruited to the case group and 108 to the control. Response rates at antenatal data collection were 87% and 85% in the case and control groups, respectively. Postnatally, the response rate was 90% in both groups.

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcomes were psychological morbidity in the antenatal and postnatal periods, infant bonding in the postnatal period and psychosocial implications of HG. Secondary outcomes were the effects of severity and longevity of HG and assessment of correlation between Edinburgh Postnatal Depression Scale scores and maternal-to-infant bonding scores.

RESULTS

Antenatally, 49% of cases had probable depression compared with 6% of controls (OR 14.4 (5.29 to 39.44)). Postnatally, 29% of cases had probable depression versus 7% of controls (OR 5.2 (1.65 to 17.21)). There was no direct association between HG and infant bonding. 53% of women in the HG group reported needing four or more weeks of sick leave compared with 2% in the control group (OR 60.5 (95% CI 8.4 to 2535.6)).

CONCLUSIONS

Long-lasting psychological morbidity associated with HG was evident. Significantly more women in the case group sought help for mental health symptoms in the antenatal period, however very few were diagnosed with or treated for depression in pregnancy or referred to specialist perinatal mental health services. HG did not directly affect infant bonding. Women in the case group required long periods off work, highlighting the socioeconomic impact of HG.

Evaluation of Maternal Serum 25-Hydroxyvitamin D Levels in Patients with Hyperemesis Gravidarum at Early Gestational Weeks

Aim: The aim of this study was to compare vitamin D levels between pregnant women with hyperemesis gravidarum before 12 weeks of gestation and healthy pregnant women at similar ages. Methods: Sixty pregnancies with hyperemesis gravidarum and 60 age compatible healthy pregnancies applied to our facility were included in the study. Demographic characteristics, maternal thyroid function tests and 25-Hydroxyvitamin D levels were evaluated. Student t test was used for the variables with normal distribution and Mann-Whitney U test was used to analyze the variables without normal distribution. Results: Only one pregnant woman had normal vitamin D levels (>30ng/ml), whereas 71 patients had deficiency (10-30 ng/ml), and 48 had severe deficiency (<10 ng/ml). The mean vitamin D level of the total 120 pregnancies was 11.9±5.00 ng/ml (9.92±3.67 ng/ml in case group, 13.88±5.38 ng/ml in control group). The mean value of vitamin D was found to be significantly lower in hyperemesis gravidarum. 45% (n=27) of the pregnant women had vitamin D deficiency, whereas 55% (n=33) of them had severe deficiency. Free T3 and T4 levels were significantly higher than the control group, and thyroid-stimulating hormone level was significantly lower. Conclusion: Vitamin D levels of pregnant women with hyperemesis gravidarum were significantly lower. Vitamin D deficiency should be considered in patients with hyperemesis gravidarum. Keywords: pregnancy, hyperemesis gravidarum, Vitamin D deficiency

Nausea, vomiting and poor appetite during pregnancy and adverse birth outcomes in rural Nepal: an observational cohort study

Background

Nausea and vomiting are experienced by a majority of pregnant women worldwide. Previous studies have yielded conflicting results regarding their impact on birth outcomes and few studies have examined this relationship in settings with limited resources. We aimed to determine the effect of nausea, vomiting and poor appetite during pregnancy on birth outcomes in rural Nepal.

Methods

Observational cohort study using data collected in two randomized, community-based trials to assess the effect of influenza immunization during pregnancy on reproductive and respiratory outcomes among pregnant women and their offspring. Pregnant women in Sarlahi District, Nepal were recruited from 2011 to 2013. Exposure was defined as nausea, vomiting or poor appetite at any point during pregnancy and by trimester; symptoms were recorded monthly throughout pregnancy. Adverse outcomes were low birth weight (LBW), preterm birth and small for gestational age (SGA). Adjusted relative risks (aRR) with 95% CIs are reported from Poisson regressions with robust variance.

Results

Among 3,623 pregnant women, the cumulative incidence of nausea, vomiting or poor appetite was 49.5% (n = 1793) throughout pregnancy and 60.6% (n = 731) in the first trimester. Significantly higher aRRs of LBW and SGA were observed among women experiencing symptoms during pregnancy as compared to symptom free women (LBW: aRR 1.20; 95% CI 1.05 1.28; SGA: aRR 1.16; 95% CI 1.05 1.28). Symptoms in the first trimester were not significantly associated with any of the outcomes. In the second trimester, we observed significantly higher aRRs for LBW and SGA (LBW: aRR 1.17; 95% CI 1.01 1.36; SGA: aRR 1.16; 95% CI 1.05 1.29) and a significantly lower aRR for preterm birth (aRR 0.75; 95% CI 0.59 0.96). In the third trimester, we observed significantly higher aRRs for LBW and SGA (LBW: aRR 1.20; 95% CI 1.01 1.43; SGA: aRR 1.14; 95% CI 1.01 1.29).

Conclusions

Symptoms of nausea, vomiting or poor appetite during pregnancy are associated with LBW, SGA and preterm birth in a setting with limited resources, especially beyond the first trimester.

Severe nausea and vomiting in pregnancy: psychiatric and cognitive problems and brain structure in children

BACKGROUND

Two studies have suggested that severe prolonged nausea and vomiting during pregnancy is associated with emotional and behavioral problems in offspring, with smaller sample size and short-term follow-up. Moreover, little information is available on the role of the brain structure in the associations.

METHODS

In a US-based cohort, the association was investigated between severe prolonged nausea and vomiting in pregnancy (extending after the second trimester and termed SNVP), psychiatric and cognitive problems, and brain morphology, from the Adolescent Brain Cognitive Development (ABCD) study, from 10,710 children aged 9-11 years. We validated the emotional including psychiatric findings using the Danish National Cohort Study with 2,092,897 participants.

RESULTS

SNVP was significantly associated with emotional and psychiatric problems (t = 8.89, Cohen's d = 0.172, p = 6.9 × 10-19) and reduced global cognitive performance (t = - 4.34, d = - 0.085, p = 1.4 × 10-5) in children. SNVP was associated with low cortical area and volume, especially in the cingulate cortex, precuneus, and superior medial prefrontal cortex. These lower cortical areas and volumes significantly mediated the relation between SNVP and the psychiatric and cognitive problems in children. In the Danish National Cohort, severe nausea and vomiting in pregnancy were significantly associated with increased risks of behavioral and emotional disorders in children (hazard ratio, 1.24; 95% confidence interval, 1.16-1.33).

CONCLUSIONS

SNVP is strongly associated with psychiatric and cognitive problems in children, with mediation by brain structure. These associations highlight the clinical importance and potential benefits of the treatment of SNVP, which could reduce the risk of psychiatric disorder in the next generation.

An Atypical Case of a Common Pregnancy Issue: Appendicitis-Like Hyperemesis Gravidarum

Hyperemesis gravidarum (HG) is a severe subtype of nausea and vomiting in pregnancy (NVP) that typically affects women in their first trimester of pregnancy. Because HG is a diagnosis of exclusion, a thorough work-up ruling out organic causes must be performed. Herein, we describe a case of a pregnant woman with HG who presented with intractable pain mimicking appendicitis. While her clinical picture and ultrasound findings were only mildly consistent with appendicitis, the only therapy that provided pain relief was empiric antibiotic treatment that was prescribed due to a mildly elevated procalcitonin of 0.61. Thereby, the detection and treatment of concurrent organic causes is important as it may provide significant symptomatic relief in cases of concurrent HG.

Hyperemesis Gravidarum in First-Trimester Pregnant Saudi Women: Is Helicobacter pylori a Risk Factor?

Introduction

Hyperemesis gravidarum (HG) is a serious complication of pregnancy involving nausea and vomiting which affects all facets of the lives of many women. Helicobacter pylori infection has been linked to HG in some regions of the world. However, the prevalence of H. pylori in Saudi Arabian pregnant women and its link to HG has not been the subject of previous research. Detecting and treating H. pylori infection in women early in their pregnancies may lower the likelihood of adverse maternal outcomes. This study aims to assess the connection between the pathogenesis of HG and H. pylori infection in this population.

Methods

Forty-five pregnant women with HG were recruited from the outpatient clinic for antenatal care in the Gynecology and Obstetrics Department at King Abdulaziz University Hospital. Forty-five pregnant women without HG were matched as controls. Both groups underwent testing for the H. pylori antigen in stool samples.

Results

A statistically significant difference (P < 0.05) was observed between the cases and controls in terms of the occurrence of H. pylori. Thirty-eight women in the HG group (84.4%) tested positive for H. pylori, while the same was true of only 20 of the controls (44.4%). The mean level of blood hemoglobin in positive cases was significantly lower than that in negative cases (9.56 ± 1.29 vs. 11.90 ± 1.18 g/dl, P = 0.012).

Conclusion

H. pylori may play a contributing role in the presence of HG in the study population. It may be included with other investigations of HG, especially with cases that do not respond to conventional management and continue into the second trimester. Women with H. pylori were also more likely to suffer from anemia compared to those without the infection. For this reason, those working with pregnant women should pay close attention to those infected with H. pylori. Additional large case–control studies are necessary to better understand the part H. pylori plays and the pathogenesis of HG.

Distinct temperament and character traits in patients with hyperemesis gravidarum

Hyperemesis gravidarum (HG) is an extreme form of vomiting during pregnancy and is characterized with excessive vomiting and nausea and ketonuria, electrolyte imbalance, dehydration and severe nurtition deficiency. The etiology of HG is considered as multifactorial. Altough there is a great interest to HG in terms of psychiatric conditions, there have been limited numbers of studies that researched personality traits in patients with HG. In present study, we aimed to compare temperament and character traits between pregnant women with and without HG by Temperament and Character Inventory. 48 pregnant women with HG and 64 healthy pregnant women were included to study. The HG groups and control group were compared in terms of temperament and character traits and anxiety levels. The temperament scores of novelty seeking, harm avoidance and reward dependence were found to be similar between groups while the score of persistence was significantly lower in HG group compared with control group (p = .021). All character scores in HG group as cooperativeness, self-directedness, and self-transcendence were significantly lower compared with control groups (respectively; p = .002, p = .018 and p = .029). The scores of STAI-1 was higher in HG group compared with control group (p = .027) whereas the score of STAI-2 was found to be similar between groups. Present study is the first to demonstrate different temperament and character traits in patients with HG. We argue that our results support the psychiatric background of HG; however further studies are needed to confirm our results.
