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.

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.

Pitfalls in the assessment of gestational transient thyrotoxicosis.

Gestational transient thyrotoxicosis (GTT) is associated with direct stimulation of the maternal thyroid gland by human chorionic gonadotropin (hCG). It is characterized by slightly higher thyroid hormone and lower thyroid-stimulating hormone (TSH) levels in early pregnancy and mild or no symptoms. While GTT must be distinguished from Graves' disease (GD), which is associated with maternal and fetal complications, treated GD and new-onset GD in pregnancy are occasionally challenging to distinguish. Evaluating serum hCG levels and TSH receptor antibody (TRAb) titers can help, but the results are not irrefutable due to pregnancy-related immunosuppression. Moreover, GTT can follow unusual clinical courses in relation to some pregnancy complications. Excessive hCG production can cause severe GTT symptoms in patients with hyperemesis gravidarum, trophoblastic disease, or multiple pregnancies. Thyrotoxicosis can emerge beyond the second trimester in patients with gestational diabetes mellitus and mirror syndrome, because of delayed elevations in the hCG levels. Detailed knowledge about GTT is necessary for correct diagnoses and its appropriate management. This review focuses on the diagnosis of GTT, and, particularly, its differentiation from GD, and unusual clinical conditions associated with GTT that require comprehensive management.

History of depression and risk of hyperemesis gravidarum: a population-based cohort study.

Hyperemesis gravidarum (HG) is a pregnancy condition characterised by debilitating nausea and vomiting. HG has been associated with depression during pregnancy but the direction of the association remains unclear. The aim of this study was to assess whether previous depression is associated with HG. This is a population-based pregnancy cohort study using data from The Norwegian Mother and Child Cohort Study. The study reviewed 731 pregnancies with HG and 81,055 pregnancies without. Logistic regression analyses were performed to examine the association between a lifetime history of depression and hyperemesis gravidarum. Odds ratios were adjusted for symptoms of current depression, maternal age, parity, body mass index, smoking, sex of the child, education and pelvic girdle pain. A lifetime history of depression was associated with higher odds for hyperemesis gravidarum (aOR = 1.49, 95% CI (1.23; 1.79)). Two thirds of women with hyperemesis gravidarum had neither a history of depression nor symptoms of current depression, and 1.2% of women with a history of depression developed HG. A lifetime history of depression increased the risk of HG. However, given the fact that only 1.2% of women with a history of depression developed HG and that the majority of women with HG had no symptoms of depression, depression does not seem to be a main driver in the aetiology of HG.

Hyperemesis Gravidarum: A Review of Recent Literature.

BACKGROUND: In the United States, hyperemesis gravidarum is the most common cause of hospitalization during the first half of pregnancy and is second only to preterm labor for hospitalizations in pregnancy overall. In approximately 0.3-3% of pregnancies, hyperemesis gravidarum is prevalent and this percentage varies on account of different diagnostic criteria and ethnic variation in study populations. Despite extensive research in this field, the mechanism of the disease is largely unknown. Although cases of mortality are rare, hyperemesis gravidarum has been associated with both maternal and fetal morbidity. The current mainstay of treatment relies heavily on supportive measures until improvement of symptoms as part of the natural course of hyperemesis gravidarum, which occurs with progression of gestational age. However, studies have reported that severe, refractory disease manifestations have led to serious adverse outcomes and to termination of pregnancies. SUMMARY: Despite extensive research in the field, the pathogenesis of hyperemesis gravidarum remains unknown. Recent literature points to a genetic predisposition in addition to previously studied factors such as infectious, psychiatric, and hormonal contributions. Maternal morbidity is common and includes psychological effects, financial burden, clinical complications from nutritional deficiencies, gastrointestinal trauma, and in rare cases, neurological damage. The effect of hyperemesis gravidarum on neonatal health is still debated in literature with conflicting results regarding outcomes of birth weight and prematurity. Available therapy options remain largely unchanged in the past several decades and focus on parenteral antiemetic medications, electrolyte repletion, and nutritional support. Most studies of therapeutic options do not consist of randomized control studies and cross-study analysis is difficult due to considerable variation of diagnostic criteria. Key Messages: Hyperemesis gravidarum carries a significant burden on maternal health and US health care. Most published research on pathogenesis is observational and suggests multifactorial associations with hyperemesis gravidarum. Precise, strictly defined criteria for clinical diagnosis are likely to benefit meta-analyses of further research studies regarding pathogenesis as well as therapeutic options.

Pregnancy and liver disease.

Pregnancy associated liver diseases affect up to 3% of pregnant women and are the most frequent cause of liver dysfunction in pregnancy. When severe, they are associated with significant morbidity and mortality for both mother and infant. A rapid evaluation to distinguish them from non-pregnancy related liver dysfunction is essential, in order to facilitate appropriate management. Liver disease unrelated to pregnancy can present de novo in pregnancy, or pregnancy can occur in women with preexisting liver pathology (Table 1). Research and subsequent advances in medical care have resulted in improved but still not satisfactory maternal and fetal outcomes. In this review we provide an overview of the liver diseases specific to the pregnant state and an update on their pathogenesis, treatment and outcomes. The risks of pregnancy in women with pre-existent liver pathology is detailed and recent advances in our understanding of specific risks and outcomes are discussed.

Is there any relationship between serum sirtuin-1 level and neutrophil-lymphocyte ratio in hyperemesis gravidarum?

AIM: The aim of this study was to evaluate the relationship between serum sirtuin-1 (SIRT1) level and neutrophil-lymphocyte ratio (NLR) with hyperemesis gravidarum (HG). METHODS: Overall, 90 patients who presented with pregnancy between August 2013 and November 2014 were included in the study. The patients were divided into two groups: patients with HG (n=45) and patients without HG (control group [C]; n=45). The patients with comorbid conditions other than pregnancy (disease or medication) were excluded. In all patients, demographic data including age, body mass index (BMI), gestational week, and smoking status were recorded. Blood samples were drawn for complete blood count and measurements of blood lipid, liver enzymes, serum SIRT1, and insulin levels. NLR was calculated from CBC. RESULTS: No significant differences were detected in age, BMI, or GA between groups (P>0.05). Serum SIRT1 and NLR were found to be significantly higher in patients with HG compared with those in the control group (P=0.001 and 0.006, respectively). CONCLUSION: In HG, both SIRT1 level and NLR increased. In HG, this occurred as a response to metabolic alterations and potential inflammation.

Hyperemesis gravidarum and its relation with maternal body fat composition.

The objective of this study was to determine if maternal body fat composition and body mass index were associated with hyperemesis gravidarum (HG) in the first trimester of pregnancy. Healthy pregnant women (n = 30) without nausea and vomiting (control group) and women with HG (n = 54; study group), all with singleton pregnancy at 6-14 weeks gestational age, were included. Body mass index was measured before and during pregnancy. Visceral adipose tissue (VAT) and subcutaneous fat thickness were measured during pregnancy. Comparison of the groups revealed that VAT and pre-pregnancy body mass index but not subcutaneous fat thickness were significantly higher in the HG group versus controls. VAT and pre-pregnancy body mass index predicted 83.8% and 67.1% of HG cases, respectively. VAT and pre-pregnancy body mass index were correlated with the development of hyperemesis gravidrum and hence could be considered as predictive markers for HG.

Hydatidiform mole: age-related clinical presentation and high rate of severe complications in older women.

OBJECTIVE: The purpose of this study was to demonstrate differences in clinical presentation of hydatidiform mole between women ≥40 years and younger women. DESIGN: Retrospective study. SETTING: A tertiary referral unit in northern Italy. POPULATION: Three hundred and sixty-five women with hydatidiform mole were divided into group A (<40 years, 318 cases) and group B (≥40 years, 47 cases). METHODS: Clinical presentation between groups A and B was analyzed, also considering partial hydatidiform mole and complete hydatidiform mole. MAIN OUTCOME MEASURES: Differences in clinical presentation according to woman's age. RESULTS: In group B the diagnosis of hydatidiform mole at ≥12 gestational weeks was more frequent (p < 0.001) and the detection of ultrasound features was higher (p < 0.05) than in group A. Vaginal bleeding (p < 0.05), increased uterine volume (p < 0.0001) and hyperemesis (p < 0.05) occurred more frequently in group B. In the women with complete hydatidiform mole, group B women presented with vaginal bleeding (p < 0.001), increased uterine volume (p < 0.05) and hyperemesis (p < 0.05) more frequently than group A women. Complete hydatidiform mole was more commonly diagnosed after 12 weeks of gestation in group B (p < 0.0001). In women ≥50 years, an increased rate of disease-related complications was detected. CONCLUSIONS: The clinical features of hydatidiform mole in women ≥40 years are different from those seen in younger women. Failures in the early detection of hydatidiform mole in older women may expose them to a higher rate of severe complications.

Are there any differences in psychiatric symptoms and eating attitudes between pregnant women with hyperemesis gravidarum and healthy pregnant women?

AIM: We aimed to determine the relationship between eating attitudes and psychiatric symptoms in women with hyperemesis gravidarum (HG) and to compare these women with healthy control subjects. METHODS: The study sample included 48 women with HG, and the control group had 44 pregnant women. The patients were selected from women with HG hospitalized in the obstetric inpatient clinic. All of the participants were in the first trimester of pregnancy. The participants' sociodemographic and clinical characteristics were recorded in the obstetric clinic. All of the participants completed a Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Eating Attitudes Test (EAT) and Body Image Scale (BIS). RESULTS: Women with HG were more likely to have had a history of HG during their previous pregnancy (P<0.05). There was no significant difference between the study and control groups regarding obstetric history. Women with HG were more influenced by food that induced nausea. There was no significant difference between the study and control groups for pre-pregnancy nausea, food craving and the initial BMI (P>0.05). Depression and anxiety scores were significantly higher in women with HG (P<0.05). However, there was no significant difference between the study and control groups for body image score and eating attitude test scores (P>0.05). CONCLUSION: We suggest that HG appears to be associated with depression and anxiety symptoms rather than deterioration of eating attitudes and body image. However, these results should be confirmed by prospective and clinical studies.

Hyperparathyroid crisis presenting with hyperemesis gravidarum.

PURPOSE: Primary hyperparathyroidism during pregnancy is a rare condition, and the diagnosis may be confounded by pregnancy related conditions. Since the appropriate management reduces the maternal and fetal complications; differential diagnosis becomes quite crucial. METHOD: Clinical course of a patient with hyperparathyroid crisis will be discussed with the review of the literature. A 22-year- old, (gravida 2, para 1) woman was presented with hyperparathyroid crisis at the 11th weeks' gestation. She was hospitalized twice due to hyperemesis gravidarum. When she was admitted to the hospital for the third time due to increased vomiting and weight-loss, serum biochemistry panel was performed and it revealed severe hypercalcemia that serum Ca was 17.59 mg/dl, and she was referred to our hospital as parathyroid crisis. Maternal hypercalcemia was resolved after urgent parathyroidectomy. She was diagnosed as preeclampsia at the 30 weeks' gestation and delivered a male infant weighing 1,090 g at 33 weeks' gestation with APGAR scores 6 at 1 min, and 7 at min 5, without evidence of neonatal hypocalcemia or tetany. RESULTS: Urgent parathyroidectomy is the definite treatment in symptomatic patients with hyperparathyroidism during pregnancy. Resolving maternal hypercalcemia prevents neonatal tetany and hypocalcemia. CONCLUSION: Hyperemesis may lead to hypercalcemic crisis in patients with hyperparathyroidism, so serum Ca level should be checked in patients with hyperemesis gravidarum especially who detoriate rapidly. Although they share some common pathogenetic mechanisms, there is not enough evidence for attributing preeclampsia to primary hyperparathyroidism.

[Pregnancy during dialysis: experience in six patients]. / Embarazos exitosos en hemodiálisis crónica: experiencia de un único centro.

BACKGROUND: The frequency of pregnancies during dialysis is increasing. This condition requires changes in the dialysis schedule and nutritional approach. AIM: To report the experience in six patients with terminal kidney disease who became pregnant. MATERIAL AND METHODS: Retrospective review of medical records of women with terminal kidney disease in dialysis who became pregnant in a period of 27 years. RESULTS: We recorded six successful pregnancies among women in hemodialysis treatment aged 32 ± 4 years. The mean dialysis-time per week was 19.5 ± 2.7 hours and Kt/V was 1.55 ± 0.17. The mean systolic blood pressure was 130 ± 13.3 mmHg. The mean packed cell volume of the group increased from 22.7% during pre-gestational stage to 30.2% during third trimester of pregnancy. All patients received an intensive treatment for anemia. The most common symptom of pregnancy was hyperemesis. The mean gestational age (GA) at diagnosis was 13.4 ± 4.7 weeks. All patients had preterm deliveries at a GA of 33 ± 1.7 weeks, and 66% of offspring were appropriate for gestational age. CONCLUSIONS: A multidisciplinary approach allows high rate of successful pregnancies during hemodialysis.

[Abnormal hepatic function tests in pregnancy: causes and consequences]. / Kóros májlelet áldott állapotban: okok és teendok.

The well-known normal ranges of laboratory parameters are altered due to the broad spectrum of physiological changes as well as proinflammatory and procoagulant effects of pregnancy. Hepatic disorders of any aetiology can cause potential problems during gravidity. Most frequently toxic-effects, hepatotrop viruses (such as hepatitis B and C), metabolic syndrome and diseases with autoimmune background can be observed. When dealing with "pregnancy-specific hepatic syndromes", it is very important to consider the "timing-factors" of pathologic changes and deterioration of clinical pictures as well. Due to the progress in cholestasis management, early termination of pregnancy can be avoided in many cases. As the overlap is really broad between various hepatic disorders, a multidisciplinary cooperation of different sub-disciplines is emphasized in order to achieve proper diagnosis and curative measures at early phase.

Diplopia after Sleeve Gastrectomy: The Canary in the Coal Mine.

Wernicke's encephalopathy (WE) is a neurologic emergency requiring timely intravenous thiamine supplementation to prevent permanent neurologic deficits. Historically, the WE diagnosis was limited to individuals with alcohol use disorder. However, it is now widely recognized to occur in patients who are chronically malnourished, post-bariatric surgery, pregnant with hyperemesis gravidarum, and with severe anorexia nervosa. Here we present a young woman who developed WE after undergoing a recent sleeve gastrectomy followed by protracted emesis for several days. This case underscores the importance of performing a thorough neurological review of systems and physical exam in high-risk patients and having a low clinical threshold to initiate appropriate thiamine treatment.

Hyperemesis, gestational hypertensive disorders, pregnancy losses and risk of autoimmune diseases in a Danish population-based cohort.

The risk of some female predominant autoimmune diseases (ADs) has previously been shown to be higher in women who experience hyperemesis, gestational hypertensive disorders and idiopathic pregnancy losses. This study assessed the association between such pregnancy-related experiences and the subsequent risk of female predominant and other ADs. Our study cohort comprised 1.6 million Danish women born since 1955 for whom we had information about hyperemesis, gestational hypertensive disorders and pregnancy losses and subsequent hospital contacts for 31 ADs between 1982 and 2008. Ratios of first hospitalization rates (RRs) with 95% confidence intervals (CIs) were calculated using Poisson regression, adjusting for age, birth cohort, calendar period, marital status and childbirths. During 27.0 million person-years of follow-up 51,732 women were hospitalized with one or more ADs. Overall, compared with women without the specific pregnancy experiences, the risk of any AD was significantly increased for women with hyperemesis (RR = 1.41; 95% CI 1.30-1.51), gestational hypertensive disorders (1.21; 1.16-1.26), spontaneous abortions (1.10; 1.07-1.14), missed abortions (1.09; 1.04-1.13), stillbirths (1.25; 1.12-1.40), ectopic pregnancies (1.08; 1.02-1.14) and induced abortions (1.07; 1.04-1.09). Associations with female predominant ADs (i.e., ADs with a female:male ratio >2:1) were strongest in the first five years after the studied pregnancy experiences, but overall there was little difference between the RRs for groups of female predominant ADs and other ADs. Strong and potentially biological associations were observed for a number of specific ADs; including systemic lupus erythematosus, Graves' disease, type 1 diabetes mellitus and pernicious anemia, and for some specific ADs associations persisted even more than five years after the abnormal pregnancy experience. Abnormal pregnancies are associated with increased risk of certain ADs, possibly because of underlying immunologic or hormonal factors that predispose to both adverse pregnancy experiences and AD development.

Emergency management of hyperemesis gravidarum.

Most pregnant women experience morning sickness during the first 20 weeks of pregnancy. Often, the symptoms are mild, but recurring, nausea and vomiting; but the condition can also lead to dehydration, weight loss, electrolyte imbalance and blood volume depletion, and many women with more severe forms of the condition present to emergency departments. This article describes the presenting symptoms, causes of hyperemesis gravidarum, the associated clinical signs and complications, and the most common treatments offered.

A potential role for olanzapine in the treatment of hyperemesis gravidarum.

Hyperemesis gravidarum is a rare but potentially serious complication of pregnancy. Some women with severe symptoms and possibly psychiatric comorbidities remain symptomatic despite the use of currently available treatments. Due to its favorable safety profile, antiemetic efficacy in other conditions, and 5-HT3 antagonism, olanzapine may be a potentially useful addition to the armamentarium for management of hyperemesis gravidarum resistant to standard- of-care treatment.

Familial aggregation of hyperemesis gravidarum.

OBJECTIVE: This study was undertaken to determine whether there is familial aggregation of hyperemesis gravidarum (HG), making it a disease amenable to genetic study. STUDY DESIGN: Cases with severe nausea and vomiting in a singleton pregnancy treated with intravenous hydration and unaffected friend controls completed a survey regarding family history. RESULTS: Sisters of women with HG have a significantly increased risk of having HG themselves (odds ratio, 17.3; P = .005). Cases have a significantly increased risk of having a mother with severe nausea and vomiting; 33% of cases reported an affected mother compared to 7.7% of controls (P < .0001). Cases reported a similar frequency of affected second-degree maternal and paternal relatives (18% maternal lineage, 23% paternal lineage). CONCLUSION: There is familial aggregation of HG. This study provides strong evidence for a genetic component to HG. Identification of the predisposing gene(s) may determine the cause of this poorly understood disease of pregnancy.

The clinical management of hyperemesis gravidarum.

Hyperemesis gravidarum is a severe and disabling condition with potentially life-threatening complications. It is likely to have a multifactorial etiology which contributes to the difficulty in treatment. Treatment is supportive with correction of dehydration and electrolyte disturbance, antiemetic therapy, prevention and treatment of complications like Wernicke's encephalopathy, osmotic demyelination syndrome, thromboembolism, and good psychological support. There are abundant data on the safety of antihistamines, phenothiazines, and metoclopromide in early pregnancy and treatment should therefore not be withheld on the basis of teratogenicity concerns. Thiamine replacement is indicated in hyperemesis gravidarum to prevent development of Wernicke's encephalopathy.

Relapse of Human Chorionic Gonadotropin-Induced Hyperthyroidism and Severe Hyperemesis Gravidarum Secondary to Twin-Twin Transfusion Syndrome, With Rapid Recovery Following Fetoscopic Laser Coagulation: Case Report.

Background: Limited data have shown that, compared to uncomplicated twin pregnancies, pregnancies complicated by twin-twin transfusion syndrome (TTTS), a life-threatening condition, are associated with higher maternal serum levels of both human chorionic gonadotropin (hCG) and thyroid hormones. With the continuing expansion of assisted reproductive technologies, the rate of twin pregnancies, including those complicated by TTTS and associated hyperemesis gravidarum, is expected to increase further. Therefore, detailed descriptions of the maternal and fetal clinical outcomes of maternal thyrotoxicosis linked to TTTS can be useful for timely diagnosis and management. However, such descriptions are currently lacking in the literature. Case Presentation: We report the case of a 30-year-old woman carrying a monochorionic twin pregnancy complicated by TTTS that induced a relapse of severe hyperemesis gravidarum with overt non-autoimmune hyperthyroidism at 17 weeks of gestation. Following fetoscopic laser coagulation (FLC), both hyperemesis and hyperthyroidism improved within 1 week. Conclusions: The present experience contributes to the knowledge base on maternal thyrotoxicosis linked to TTTS and can be useful in the diagnosis and treatment of future cases; it also emphasizes the need for a high degree of clinical suspicion and for close collaboration between endocrinologists and obstetricians. Another key point is that TTTS-associated hyperemesis gravidarum and maternal hyperthyroidism should be considered in the differential diagnosis of refractory or relapsing hyperemesis gravidarum in women with monochorionic twin pregnancy, because this condition may require more stringent supportive treatment before and during the FLC procedure when the mother is overtly hyperthyroid.
