Abstract
Nausea and vomiting are common experiences and are often dreaded more than pain. This review discusses blonanserin, mirtazapine, and isopropyl alcohol as antiemetics. Blonanserin, an atypical antipsychotic with a high affinity for dopamine D2 and D3 receptors and serotonin receptor 5-HT2A, has less of a risk of extrapyramidal adverse effects. Transdermal blonanserin, available in Korea, Japan, and China in a small number of trials, has improved nausea in patients not responding to standard antiemetics. Mirtazapine is a noradrenergic and specific serotonergic antidepressant that has been used for multiple symptoms besides depression. There is little evidence that mirtazapine improves anorexia or nausea in advanced cancer but is as effective as olanzapine in reducing chemotherapy-induced nausea and vomiting. Isopropyl alcohol aromatherapy has been successfully used in the emergency department for nausea and vomiting with an onset to benefit more rapidly than standard antiemetics. Isopropyl alcohol prep pads can be used for home-going antiemetic therapy and as a bridge to treating acute nausea until standard antiemetics take effect.

Abstract
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.

Use of Mirtazapine and Olanzapine in the Treatment of Refractory Hyperemesis Gravidarum: A Case Report and Systematic Review. Case Rep Obstet Gynecol 2022; 2022:7324627. [PMID: 36105926 PMCID: PMC9467790 DOI: 10.1155/2022/7324627] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 08/09/2022] [Accepted: 08/24/2022] [Indexed: 11/18/2022] Open
Abstract
Hyperemesis gravidarum (HG) is a rare condition (1.1%) characterized by excessive vomiting, malnutrition, dehydration, and laboratorial alterations. Herein, we describe the even rarer and serious presentation of refractoriness to the usual treatment of antiemetics and parenteral nutrition, with improvement only after the use of olanzapine and mirtazapine. Two subsequent pregnancies of the same woman with HG are described, which were associated with severe weight loss, anemia, hyponatremia, hypokalemia, and mild dysfunction of liver enzymes. In the third pregnancy, the usual treatment for HG was not successful, requiring enteral nutrition and the introduction of olanzapine. In the fourth pregnancy, the patient refused to use enteral nutrition for refractory HG. Hence, the patient was started on mirtazapine at an initial dose of 15 mg/day, which was gradually increased to 30 mg/day. The patient responded well to the new regimen, as demonstrated by the decrease in symptoms, the gain of 10 kg in the pregnancy, and delivering a healthy newborn. A systematic review of literature showed 11 articles and 30 cases that successfully used mirtazapine in HG. Good clinical outcomes were seen with 4 days of the treatment and at an initial dose of 15 mg/day. However, most of these reports were from psychiatric profiles, with a predominance of depression and anxiety symptoms, and a poor description of the obstetric conditions and the disease progression itself. Pulmonary hypertension was described in one case and neonatal hyperexcitability in another. The case described in this paper reinforces the idea that mirtazapine and olanzapine can be considered in refractory HG, with good results. In the world literature, this is the second case of HG that has been successfully treated with olanzapine and the first in Latin America treated with mirtazapine.

Abstract
OBJECTIVE To investigate the association between mirtazapine exposure in pregnancy and risk of specific adverse pregnancy outcomes. METHODS A register-based nationwide cohort study was conducted including all registered pregnancies in Denmark from 1997 to 2016. Mirtazapine-exposed pregnancies were compared with mirtazapine unexposed pregnancies in a 1:4 ratio matched according to propensity scores. Outcomes were major congenital malformations analyzed using log binomial models, and spontaneous abortion, stillbirth and neonatal death analyzed using Cox proportional hazard regression. RESULTS From a source population of 1,650,649 pregnancies, the propensity score-matched cohort included 4475 pregnancies (895 mirtazapine exposed) in the analysis of major congenital malformations. The analyses of spontaneous abortion included 9 500 pregnancies (1900 mirtazapine exposed), and for the analyses of stillbirths and neonatal deaths 9725 (1 945 mirtazapine-exposed) and 4485 pregnancies (897 mirtazapine-exposed) were included, respectively. Thirty-one (3.5%) children were diagnosed with major congenital malformation among the mirtazapine exposed compared with 152 (4.3%) among the unexposed pregnancies (OR=0.81, 95% CI 0.55-1.20). Spontaneous abortion occurred in 237 (12.5%) of the mirtazapine exposed compared with 931 (12.3%) of the unexposed pregnancies (HR = 1.04%, 95% CI 0.91-1.20). The analyses revealed no increased risk of stillbirth (HR = 0.88%, 95% CI 0.34-2.29) or neonatal death (HR = 0.60%, 95% CI 0.18-2.02). CONCLUSIONS In this nationwide Danish register study, mirtazapine exposure in pregnancy was not associated with major congenital malformations, spontaneous abortion, stillbirth, or neonatal death. Clinicians and patients can be reassured that mirtazapine is safe in pregnancy.

Abstract
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.

Abstract
INTRODUCTION Current pharmacological treatment options for hyperemesis gravidarum have been introduced based on scarce evidence and are often not sufficiently effective. Several case reports suggest that mirtazapine, an antidepressant, may be an effective treatment for hyperemesis gravidarum, but so far there are no controlled trials investigating the potential effect of mirtazapine on hyperemesis gravidarum. The antiemetic ondansetron is currently widely used to treat hyperemesis gravidarum despite sparse evidence of effect in pregnant women. This study aims to investigate the effect of mirtazapine on hyperemesis gravidarum while also providing data on the effect of ondansetron. METHODS AND ANALYSIS This randomised double-blind placebo-controlled multicentre trial will be conducted in eight Danish hospitals. One hundred and eighty pregnant women referred to secondary care for hyperemesis gravidarum will be randomly allocated to 14-day treatment with either mirtazapine, ondansetron or placebo. Main inclusion criterion will be Pregnancy Unique Quantification of Emesis (PUQE-24) score ≥13 or PUQE-24 score ≥7 if accompanied by weight loss >5% of pre-pregnancy weight or hospitalisation. Participants are eligible regardless of whether other antiemetics, including ondansetron, have been tried. The coprimary outcomes are effects of mirtazapine and ondansetron, respectively, on PUQE-24 score tested hierarchically on day 2 and day 14. Secondary outcomes include, but are not limited to, differences between the three groups in number of daily vomiting episodes, dropout due to treatment failure, use of rescue medication, weight change and side effects. ETHICS AND DISSEMINATION The trial has been approved by the Regional Committees on Health Research Ethics in the Capital Region of Denmark, the Danish Medicines Agency and the Danish Data Protection Agency. Results will be published in peer-reviewed journals and submitted to relevant conferences. TRIAL REGISTRATION NUMBER NCT03785691.

Abstract
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.
