Análise dos efeitos em fetos expostos à hiperêmese gravídica durante a gravidez / Analysis of the effects on fetuses exposed to hyperemesis gravidarum during pregnancy

INTRODUÇÃO: De etiologia desconhecida, a hiperêmese gravídica é um quadro caracterizado por vômitos persistentes, perda de 5% ou mais do peso, cetonúria, hipocalemia e desidratação. Acredita-se que a gonadotrofina coriônica humana (hCG) provoque aumento das náuseas e vômitos por meio de seu estímulo à produção de estrogênio pelo ovário, provocando a exacerbação dos sintomas do "enjoo matinal". OBJETIVO: Logo, essa revisão narrativa tem como objetivo analisar as repercussões fetais do quadro de hiperêmese gravídica. MÉTODOS: Foram realizadas buscas em Sistema Online de Busca e Análise de Literatura Médica - MEDLINE®. Sendo utilizadas os Medical Subject Headings (MeSh terms) e seus sinônimos: "hyperemesis gravidarum", "fetal risks", sendo selecionados ao todo 13 artigos. RESULTADOS: Os estudos demonstraram que a hiperêmese gravídica pode trazer malefícios para mãe e feto. A gestante pode apresentar distúrbios eletrolíticos, encefalopatia de Wernicke, fraqueza muscular, disfunções emocionais como depressão, ansiedade e estresse pós-traumático. DISCUSSÃO: Os estudos revelaram que a patologia pode estar relacionada ao risco aumentado para desfechos adversos no nascimento, como baixo peso ao nascer, nascimento prematuro e pequena estatura para idade gestacional. Ademais, alguns estudos relataram os riscos prejudiciais no neurodesenvolvimento do recém-nascido, como problemas psicológicos e comportamentais na idade adulta, redução à sensibilidade à insulina, e comorbidades (obesidade e doenças cardiovasculares) além de distúrbios de desenvolvimento neuropsicomotor. CONCLUSÃO: Gestantes que apresentam o quadro de hiperêmese gravídica devem ser regularmente acompanhadas com consultas entre 1 a 2 semanas, conforme a gravidade do caso e o mais precocemente possível tratadas, a fim de evitar maiores complicações tanto maternas quanto fetais.

INTRODUCTION: Of unknown etiology, hyperemesis gravidarum is a condition characterized by persistent vomiting, 5% or more weight loss, ketonuria, hypokalemia and dehydration. Human chorionic gonadotropin (hCG) is believed to cause increased nausea and vomiting through its stimulation of estrogen production by the ovary, causing exacerbation of "morning sickness" symptoms. OBJECTIVE: Thus, this narrative review aims to analyze the fetal repercussions of hyperemesis gravidarum. METHODS: Searches were performed in the Online Medical Literature Analysis and Search System - MEDLINE®. The Medical Subject Headings (MeSh terms) and their synonyms were used: "hyperemesis gravidarum", "fetal risks", being selected a total of 13 articles. RESULTS: The studies showed that hyperemesis gravidarum can bring harm to mother and fetus. The pregnant woman may present electrolyte disturbances, Wernicke's encephalopathy, muscle weakness, emotional dysfunctions such as depression, anxiety, and post-traumatic stress. DISCUSSION: The studies revealed that hyperemesis gravidarum may be associated with increased risk of adverse outcomes. Furthermore, some studies reported harmful risks in neurodevelopment of the newborn, such as psychological and behavioral problems in adulthood, reduced sensitivity to insulin, and comorbidities (obesity and cardiovascular diseases) and neurodevelopmental disorders. CONCLUSION: Pregnant women who present with hyperemesis gravidarum should be followed up with consultations between 1 to 2 weeks, according to the severity of the case and treated as early as possible in order to avoid further complications both maternal and fetal.

Wernicke-Korsakoff Syndrome associated with hyperemesis gravidarum and fetal death: Case report and literature review / Síndrome de Wernicke-Korsakoff associado a hiperêmese gravídica e morte fetal: Relato de caso e revisão de literatura

We describe a clinical case of a pregnant patient with hyperemesis gravidarum who progressed to abortion, Wernicke's encephalopathy, and Korsakoff's psychosis, all related to thiamine deficiency. The patient presented symptoms of disorientation, nonspecific limb movements, and fever, initially treated with metronidazole and ceftriaxone for suspected infected abortion. Subsequently, the patient was diagnosed with retained and infected abortion, and thiamine replacement therapy was initiated with an intravenous loading dose of 900 mg/day. During hospitalization, the patient presented with tetraparesis, nystagmus, decreased level of consciousness, anterograde and retrograde amnesia, confabulation, and aphasia. Magnetic resonance imaging showed lesions in the pons, typical of Wernicke's encephalopathy. The patient was empirically treated with acyclovir and ampicillin and showed clinical improvement. The text also provides a brief narrative review of the literature on the topic.

Descrevemos um caso clínico de uma paciente grávida com hiperêmese gravídica que evoluiu para aborto, Encefalopatia de Wernicke e Psicose de Korsakoff, ambas relacionadas à deficiência de tiamina. A paciente apresentou sintomas de desorientação, movimentos inespecíficos dos membros e febre, sendo, inicialmente, tratada com metronidazol e ceftriaxona por suspeita de aborto infectado. Posteriormente, a paciente foi diagnosticada com aborto retido e infectado e iniciou-se a reposição de tiamina com dose endovenosa de ataque de 900 mg/dia. Durante o internamento, a paciente apresentou tetraparesia, nistagmo, rebaixamento do nível de consciência, amnésia anterógrada e retrógrada, confabulação e afasia. A ressonância magnética mostrou lesões na ponte, típicas da Encefalopatia de Wernicke. A paciente foi tratada com aciclovir e ampicilina empiricamente e apresentou melhoras no quadro clínico. O texto também faz uma breve revisão narrativa da literatura sobre o tema.

Hospitalizaciones por hiperémesis gravídica durante el 2018-2021 en Chile / Hospitalizations for hyperemesis gravidarum during 2018-2021- in Chile

Introducción: La hiperémesis gravídica (HG) se caracteriza por más de 3 episodios diarios de vómitos persistentes y baja de peso. Frente a un puntaje PUQE mayor a 12 requerirá manejo intrahospitalario. El objetivo de esta investigación es calcular la tasa de egreso hospitalario (TEH) por HG, en el periodo 2018 a 2021 en Chile. Metodología: Estudio observacional, descriptivo. Sobre egresos hospitalarios por HG entre los años 2018-2021 en Chile (n=4.515) según grupo etario y días de estadía, datos del Departamento de Estadística e Información de Salud. Se calculó TEH, No se requirió comité de ética. Resultados: La TEH para el periodo seleccionado fue de 16,93/100.000 habitantes, con una disminución a través de los años de estudio, siendo el menor el año 2020 con 14,11/100.000 habitantes mujeres. El grupo etario con mayor TEH fue el de 20-44 años con 30,8. El promedio de estadía hospitalaria fue de 3,65 días. Discusión: La disminución de hospitalizaciones el año 2020 puede deberse a la pandemia por COVID-19, en la que se reporta una disminución de hospitalizaciones en patologías no respiratorias. Con respecto al grupo etario con mayor TEH, puede deberse a que se trata del periodo fértil de las mujeres, generando más embarazos y casos de HG a diferencia de las edades extremas de este estudio. No hay diferencia significativa en días de estadía hospitalaria según grupo etario. Conclusión: Es importante estudiar y educar sobre esta patología para su prevención y continuar disminuyendo posibles hospitalizaciones y complicaciones por HG.

Introduction: Hyperemesis gravidarum is characterized by more than 3 daily episodes of persistent vomiting and weight loss. Patients with a PUQE score more than 12 points will require intrahospital treatment. The objective of this study is to calculate the Hyperemesis gravidarum hospital discharge rate during the years 2018 to 2021 in Chile. Methodology: It is an observational-descriptive study about Hyperemesis gravidarum hospital discharge rate during the years 2018 to 2021 in Chile (n=4.515) according to age rate and days of hospital stay, the data was taken from Departamento de Estadística e Información de Salud. The Ethics Committee was not needed. Results: The hospital discharge rate during the selected period was 16,93/100.000 habitants, decreasing through the years, being the year 2020 the one with the lower rate 14,11/100.000 women, the age group with the highest rate was 20 - 44 years with 30,8. The average of hospital stay was 3,65 days. Discussion: The decrease in the number of hospitalizations during 2020 may be due to the COVID-19 pandemic in which it was reported a decrease of hospitalization in non respiratory pathologies. According to the age group with the highest rate it may be explain because it is the fertile period of women, causing more number of pregnancy and cases of Hyperemesis gravidarum, unlike the other grupo of ages There is no significant difference in days of hospital stay according to age group Conclusion: It is important to study and educate about this pathology for its prevention and to continue reducing HG hospitalizations and complications.

Tumor trofoblástico de sitio placentario secundario a mola parcial. Reporte de un caso / Placental site trophoblastic tumor secondary to partial mole. Report of a case

Resumen ANTECEDENTES: La enfermedad trofoblástica gestacional es un padecimiento que incluye un grupo de tumores placentarios, consecuencia de una proliferación anormal del tejido del trofoblasto. Se caracteriza por una excesiva elevación de la gonadotrofina coriónica humana que se considera diagnóstica y un predictor pronóstico. CASO CLÍNICO: Paciente de 23 años con hiperémesis gravídica y aumento del tamaño del útero mayor para las siete semanas de gestación y cuantificación de las concentraciones de HGC anormalmente elevadas en comparación con su valor basal. Se descartaron los diagnósticos diferenciales de mola parcial hidatiforme, mola completa y embarazo múltiple. Se concluyó que se trataba de enfermedad trofoblástica gestacional. Se procedió a la evacuación de la cavidad uterina de la que se extrajeron abundantes porciones de tejido ovoconformacional y molariforme. El informe de Patología fue: útero arcuato con tumor de sitio placentario, endometritis crónica, cervicitis con metaplasia escamosa, quiste de Nabot y endometrio proliferativo tardío. CONCLUSIÓN: Puesto que las pacientes con enfermedad trofoblástica gestacional suelen tener un pronóstico sombrío se sugiere la histerectomía simple para llegar a la curación. Por la agresividad del tumor y resistencia a otros tratamientos es indispensable el monitoreo riguroso semanal de la cuantificación de la HCG.

Abstract BACKGROUND: Gestational trophoblastic disease is a condition that includes a group of placental tumors resulting from abnormal proliferation of trophoblast tissue. It is characterized by an excessive elevation of human chorionic gonadotropin which is considered diagnostic and a prognostic predictor. CLINICAL CASE: 23-year-old patient with hyperemesis gravidarum and uterine enlargement greater than 7 weeks' gestation and abnormally elevated HGC levels compared to baseline. The differential diagnoses of hydatidiform partial mole, complete mole and multiple pregnancy were ruled out. It was concluded that it was gestational trophoblastic disease. The uterine cavity was evacuated and abundant portions of ovoconformal and molariform tissue were extracted. The pathology report was: arcuate uterus with placental site tumor, chronic endometritis, cervicitis with squamous metaplasia, Nabot's cyst and late proliferative endometrium. CONCLUSION: Since patients with gestational trophoblastic disease usually have a dismal prognosis simple hysterectomy is suggested to reach cure. Because of the aggressiveness of the tumor and resistance to other treatments, rigorous weekly monitoring of HCG quantification is indispensable.

Encefalopatía de Wernicke como complicación de la hiperemesis gravídica / Wernicke's encephalopathy as complication of hyperemesis gravidarum

RESUMEN Introducción: La hiperemesis gravídica provoca complicaciones neurológicas potencialmente letales como la encefalopatía de Wernicke, enfermedad aguda debida a la deficiencia de vitamina B1 en el cerebro. Objetivo: Presentar un caso clínico inusual de encefalopatía de Wernicke, como complicación de la hiperemesis gravídica. Caso clínico: Paciente de 42 años de edad y gestación de 12,4 semanas que ingresó por hiperemesis gravídica y luego se trasladó a la unidad de cuidados intensivos. Se solicitó valoración por Neurología al referir mareos, visión borrosa e incoordinación de los movimientos. Al examen físico presentó somnolencia, bradipsiquia, desorientación en tiempo y espacio, nistagmo horizontal y rotatorio bilateral, y ataxia del tronco. La resonancia magnética mostró hiperintensidad de señales en el tálamo, alrededor del III ventrículo, en el fórnix, corteza y subcorteza cerebral. Se planteó una encefalopatía de Wernicke secundaria a hiperemesis gravídica. La paciente evolucionó de forma favorable con la administración de vitamina B1 y esteroides. Conclusiones: La asociación entre hiperemesis gravídica y encefalopatía de Wernicke es poco frecuente, pero de consecuencias graves. El diagnóstico y el tratamiento oportuno son fundamentales para la disminución del riesgo de secuelas.

ABSTRACT Introduction: Hyperemesis gravidarum causes potentially lethal neurological complications such as Wernicke's encephalopathy, an acute disease due to vitamin B1 deficiency in the brain. Objective: To present an unusual clinical case of Wernicke encephalopathy, as a complication of hyperemesis gravidarum. Clinical case: 42-year-old patient with a 12.4-week gestation who was admitted for hyperemesis gravidarum and later transferred to the intensive care unit. Neurology assessment was requested when referring to dizziness, blurred vision and incoordination of movements. On physical examination, she presented drowsiness, bradypsychia, disorientation in time and space, bilateral horizontal and rotatory nystagmus, and trunk ataxia. Magnetic resonance imaging showed hyperintensity of signals in the thalamus, around the third ventricle, in the fornix, cortex and cerebral subcortex. Wernicke encephalopathy secondary to hyperemesis gravidarum was considered. The patient evolved favorably with the administration of vitamin B1 and steroids. Conclusions: The association between hyperemesis gravidarum and Wernicke encephalopathy is rare, but with serious consequences. Prompt diagnosis and treatment are essential to reduce the risk of sequelae.

Hematological Parameters to Predict the Severity of Hyperemesis Gravidarum and Ketonuria / Parâmetros hematológicos para prever a gravidade da hiperêmese gravídica e da cetonúria

Abstract 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 Themean 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.

Resumo Objetivo A hiperêmese gravídica (HG) é uma complicação da gravidez que pode evoluir com náuseas e vômitos persistentes. O objetivo deste estudo é avaliar a relação entre os parâmetros hematológicos e a HG. Método Foram incluídas neste estudo 532 gestantes com HG internadas no Departamento de Obstetrícia e Ginecologia entre março de 2019 e fevereiro de 2021, e 534 gestantes saudáveis com características semelhantes às do grupo de caso. Os parâmetros hematológicos foram comparados entre gestantes com e sem HG. Além disso, os parâmetros hematológicos foram comparados entre as pacientes com HG de acordo com a gravidade da cetonúria. Resultados A média de idade do grupo GH (n=532) foi de 26,3 ± 4,1 anos, e a do grupo de controle (n=534) foi de 25,9 ± 4,8 anos. Entre as pacientes com HG, 46% (n=249) tinham cetona(+), 33% (n=174), cetona(++), e 21% (n=109), cetona (+++). A razão de neutrófilos para linfócitos (RNL) e a razão de plaquetas para linfócitos (RPL) forammaiores no grupo HG do que no grupo de controle: 3,8 (2,8-5,8)/3,2 (2,6-4,0); p<0,001; e 135,2 ± 30,4/108,9 ± 62,2; p<0,001, respectivamente). A contagem de neutrófilos, a RNL e a RPL foram maiores no grupo com cetona(+++) do que nos grupos comcetona(+) e cetona(++): 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; e 149,9 ± 48,0/135,9 ± 65,7; p<0,001, respectivamente. O nível médio de hemoglobina corpuscular (MHC), a RNL e a RPL foram identificados como preditores independentes da presença de HG e do nível de positividade de cetona em pacientes com HG. Conclusão A RNL e RPL estavam elevadas em pacientes com HG, o que sugere a sua atividade inflamatória. Elas podem ser marcadores importantes associados à presença e à gravidade da HG.

Síndrome de Hamman em gestante: relato de caso / Hamman syndrome in pregnant women: case report

A síndrome de Hamman foi descrita pela primeira vez por Louis Hamman, em 1939, como "enfisema mediastinal espontâneo" e corresponde à presença de ar livre no mediastino, sem relação com trauma e/ou procedimentos invasivos na região torácica. A condição apresenta sintomas inespecíficos como dor torácica, dispneia, tosse, disfonia, disfagia e dor cervical. Devido aos sinais e sintomas inespecíficos, essa condição pode ser subdiagnosticada, contribuindo para a sua baixa incidência. O diagnóstico é estabelecido com exames de imagem como radiografia e tomografia computadorizada de tórax. No relato de caso descrito, temos uma paciente de 31 anos, gestante, G2P1A0, que desenvolve a síndrome concomitantemente a episódios de hiperêmese gravídica com cinco semanas e cinco dias de idade gestacional. O objetivo deste relato concentra-se em destacar essa hipótese diagnóstica para assistência adequada à paciente, uma vez que tal condição não faz parte do escopo cotidiano dentro da obstetrícia.(AU)

Hamman's syndrome was first described by Louis Hamman in 1939 as "spontaneous mediastinal emphysema" and is characterized by the presence of air in the mediastinum, unrelated to trauma, and/or invasive procedures in the thoracic region. The condition presents nonspecific symptoms such as thoracic pain, cervical pain, dyspnea, cough, and dysphonia. Due to the nonspecific signs and symptoms, this condition can be misdiagnosed, contributing to its low incidence. A diagnosis is established through imaging examinations such as chest radiography and computerized tomography. Here, we report the case of a 31-year-old female who developed Hamman's syndrome concomitantly with episodes of severe hyperemesis when she was five weeks and five days pregnant. Hamman's syndrome is a rare presentation in the field of obstetrics. This report seeks to highlight how Hamman's syndrome was diagnosed, discuss the care given to the patient, and explain the correlation between hyperemesis gravidarum and Hamman's syndrome.(AU)

Wernicke encephalopathy as a complication of hyperemesis gravidarum: case report / Encefalopatia de Wernicke como complicação de hiperêmese gravídica: relato de caso

Abstract Wernicke encephalopathy (WE) is an acute neurological disorder resulting from vitamin B1 deficiency, which is common in chronic alcoholism. We report a rare case of WE due to hyperemesis gravidarum in a 25-year-old pregnant patient at 13 weeks and 5 days of gestation. Initially, the disease manifested as weakness, mental confusion, anterograde amnesia, and visual and auditory hallucinations. The diagnosis was established after the detection of suggestive findings of WE in the thalamus by magnetic resonance imaging (MRI) and a rapid improvement in the patient's clinical status subsequent to treatment with thiamine. Hyperemesis is a rare cause of WE, which makes the reported case important in the literature and reinforces the need for attention in clinical practice to rare but important complications of this common condition (hyperemesis gravidarum).

Resumo A encefalopatia de Wernicke (EW) é uma condição neurológica aguda resultada da deficiência de vitamina B1, muito comum em etilistas crônicos. Relatamos um caso de EW secundário a um quadro de hiperêmese gravídica em uma gestante de 25 anos de idade e 13 semanas e 5 dias de idade gestacional. Inicialmente essa desordem se manifestou como fraqueza, confusão mental, amnésia anterógrada, e alucinações auditivas e visuais. O diagnóstico foi estabelecido depois da detecção de achados sugestivos de EW na ressonância nuclear magnética e da melhora do quadro clínico com reposição de tiamina. A hiperêmese gravídica não é uma causa comum de EW, o que faz com que o presente relato de caso tenha importância na literatura e reforça a necessidade de atenção na prática clínica para complicações raras mas importantes desse quadro tão comum (hiperêmese gravídica).

Effect of abnormal liver function test on maternal and perinatal outcome in pregnancy: observational study

Background: The present study was conducted with the objective to assess the spectrum of liver disease in pregnancy, and its course and effect on maternal and fetal outcomes.Methods: The present study was conducted as a prospective follow up study in the department of Obstetrics and Gynaecology, J. K. Hospital for a period of 1 year. The pregnant women between the ages of 18-35 years presenting with symptoms suggestive of underlying liver disease were selected. Socio demographic details and clinical history was obtained from all the participants and they were subjected to liver function test (LFT). All patients were followed till 2 weeks post-partum period. The maternal and fetal outcomes were noted.Results: The following results were obtained: pregnancy-induced hypertension (PIH) was the most common cause of abnormal LFT (46.66%), about 57.5% patients delivered at term, 63.3% patients delivered vaginally, mostly cases delivered a term healthy neonate between 2.5-3.0 kg weight with Apgar score >7 at 5 minutes after birth and maternal complications were seen in 10.82% cases.Conclusions: Our study shows that though liver disease is uncommon in Indian pregnant women, but it is associated with high maternal and perinatal morbidity. A high index of suspicion of liver disease, early diagnosis, prompt referral to a higher centre when required, appropriate supportive management, and a proactive policy of early delivery when indicated may improve the maternal and fetal outcomes in pregnant women with liver disease. Thus LFT should be conducted as a routine investigation in all pregnant females during first and second trimester.

Prevalence of hyperemesis gravidarum and associated risk factors among pregnant women in a tertiary health facility in Northeast, Nigeria

Background: One of the commonest symptoms observed in pregnant women before the 20th week of gestation is nausea and vomiting, an exaggeration of these symptoms hyperemesis gravidarum (HEG) could result in maternal and fetal catastrophes and even death. The objective of this study was to determine the prevalence and associated risk factors for hyperemesis gravidarum among pregnant women at booking.Methods: A prospective institutional based study design was done among 452 pregnant women seen at booking in a tertiary hospital in Northeast Nigeria from the 1st February 2019 to 30th June 2019. Data was summarized using descriptive statistics. OR was used to measure significant risk.Results: The observed prevalence of hyperemesis gravidarum among pregnant women in the study is 44.9%. The Majority (81.4%) of these women were between the age range of 21 and 35 years. Mean age of 27 years. Multiparity (33.4%), previous (44.9%) and family history of HEG (31.6%) were identified as important risk factors for developing HEG. Grand multiparity (11.5%) and gestational age less than 13 weeks (6.64%) were however less likely observed to be risks for HEG.Conclusions: HEG is a common problem in pregnancy with almost half of the number of pregnant women at booking affected. Multiparity and past history of HEG are pointers to developing the condition and it should be looked out for among at risk group of pregnant women, so that early intervention can be instituted to avoid any possible adverse outcome.

Structural Modeling and Validation of Growth/Differentiation Factor 15 [NP_004855] Associated with Pregnancy Complication- Hyperemesis Gravidarum.

Background: Hyperemesis Gravidarum (HG) is acommon pregnancy complication that occurs in0.3–2% of pregnancies. Growth/Differentiation Factor(GDF) 15 serum levels are abnormally high in patientsassociated with HG. In silico analysis providesinformation about structure and function of GDF15.Aim and Objectives: The aim of this study was to enlistbiochemical and functional properties of GDF15protein and determine its three-dimensional structure,as GDF15 is known to be associated with risk of HG.Material and Methods: The PDB file of GDF15[NP_004855] was created by RaptorX structureprediction server. The UCLA-DOE server was used tovisual analysis of crystal structure of protein. Thevalidation for structure models was performed by usingPROCHECK. Model quality estimates were based onthe QMEAN and ProSA. Results: The model showedgood stereo-chemical property in terms of G-factorvalue -0.64, that indicates geometry of modelcorresponds to probability conformation with 95%residue in the favored region of Ramachandran plot,showing high accuracy of model prediction. The Zscore of -4.04 predicted by ProSA represents the goodquality of the model. The energy plot shows the localmodel quality by plotting knowledge-based energies asa function of amino acid sequence position.Conclusion: The generated model could be supportiveto understand the structure and functionalcharacteristics of Homo sapiens growth/differentiationfactor 15 [NP_004855]. As abnormal high serum levelsof GDF15 were observe in patients associated with HG.Therefore, the structure model of GDF15 [NP_004855]is useful to understand its role in development of HG. InSilico docking study could be explain the molecularassociation of GDF15 [NP_004855] with HG and newdrug designing, for that structure model is very useful.

Mielinolisis extrapontina en una paciente embarazada, con hiperémesis e hiponatremia. Reporte de un caso / Extrapontine myelinolysis in a pregnant with hyperemesis and hyponatremia. A case report

Resumen: ANTECEDENTES: La mielinolisis extrapontina forma parte del síndrome de desmielinización osmótica que lesiona los oligodendrocitos y ocasiona la pérdida de mielina en regiones del sistema nervioso central diferentes al puente del tronco encefálico. Se origina por la corrección rápida de sodio en pacientes con hiponatremia y en mujeres embarazadas se asocia con hiperémesis gravídica. CASO CLÍNICO: Paciente indígena, de 32 años, enviada a un hospital universitario de alta complejidad en Bogotá, desde un territorio de la Amazonia colombiana, en el marco de un nuevo modelo de salud, con embarazo de 15 semanas, quien tuvo un episodio convulsivo, afasia y automatismo bucal, con antecedente de hiperémesis gravídica y otro episodio de hiperémesis con hiponatremia un mes antes. Inicialmente se sospechó eclampsia y neuroinfección; se implementó tratamiento para la corrección rápida del sodio y prescripción de anticonvulsivos. La resonancia magnética cerebral fue compatible con mielinolisis extrapontina. Luego de un mes regresó a su territorio de origen para rehabilitación. Tuvo parto domiciliario a las 38.3 semanas y acudió al hospital para el alumbramiento. CONCLUSIONES: La mielinolisis extrapontina debe considerarse en el diagnóstico diferencial entre embarazo con cuadro neurológico agudo y antecedente de hiperémesis e hiponatremia. Es importante integrar, sistemáticamente, hospitales universitarios o de alta complejidad en los territorios rurales para optimizar el diagnóstico y tratamiento de estas pacientes.

Abstract: BACKGROUND: Extrapontine myelinolysis is part of the osmotic demyelination syndrome, being an acute non-inflammatory demyelinating disease caused by hyperosmotic stress that injures oligodendrocytes and causes myelin loss in regions of the central nervous system other than the pons of the brain stem. Primarily caused by a rapid sodium correction in patients with hyponatremia, in pregnant women its most frequent association is with hyperemesis gravidarum. CLINICAL CASE: A 32-year-old indigenous woman was referred to a university hospital of high complexity, in Bogotá, from a territory of the Colombian Amazon, within the framework of a new health care model, with a 15-week pregnancy, who had a convulsive episode, aphasia and oral automatism, and a recent history of hyperemesis gravidarum. Another history of hyperemesis and hyponatremia a month ago. Initially, eclampsia and neuroinfection were suspected, a rapid correction of sodium, anticonvulsant, remission and management in the intensive care unit was performed. MRI was compatible with extrapontin myelinolysis. After a month she returned to the territory of origin for rehabilitation. She had a home delivery at 38.3 weeks and went to the hospital for placental delivery. CONCLUSION: Extrapontin myelinolysis should be considered in the differential diagnosis between pregnancy with acute neurological symptoms conditions and a history of hyperemesis or hyponatremia. In case of a repeated history of acute hyponatremia in pregnant women with hyperemesis, chronicity should be considered. It is recommended to integrate university hospitals to rural territories to optimize the diagnosis and management of this type of cases.

Enfermedades hepáticas y embarazo / Liver diseases and pregnancy

Resumen La prevalencia de las enfermedades hepáticas en el embarazo no es despreciable, ya que estas se presentan en 3%-5% de todas las gestaciones. Entre las múltiples causas se encuentran cambios fisiológicos del embarazo; enfermedad hepática preexistente, siendo las más comunes las enfermedades colestásicas (colangitis biliar primaria y colangitis esclerosante primaria), hepatitis autoinmune, enfermedad de Wilson, hepatitis virales crónicas, cirrosis establecida de cualquier etiología y paciente con historia de trasplante hepático; enfermedad hepática adquirida durante el embarazo, siendo las principales las hepatitis virales, la toxicidad inducida por medicamentos y la hepatolitiasis; hepatopatía relacionada con el embarazo, en la cual se encuentran 5 entidades principales: hiperémesis gravídica, colestasis intrahepática del embarazo, preeclampsia, síndrome HELLP e hígado graso del embarazo. La severidad de estas entidades tiene una amplia gama de presentaciones, desde la paciente que es completamente asintomática, hasta la falla hepática aguda e incluso la muerte. La gravedad del cuadro se asocia con una morbilidad y mortalidad significativas tanto para la madre como para el feto, lo cual hace que una evaluación rápida, diagnóstico certero y manejo apropiado por un equipo multidisciplinario (incluida obstetricia de alto riesgo, hepatología, gastroenterología y radiología intervencionista), en un servicio que tenga la posibilidad de ofrecer trasplante hepático, sean fundamentales para obtener buenos desenlaces.

Abstract Liver diseases develop in 3% to 5% of all gestations. Among the causes are: 1. Physiological changes of pregnancy. 2. Pre-existing liver diseases and conditions. The most common are cholestatic diseases such as primary biliary cholangitis and primary sclerosing cholangitis. Others include autoimmune hepatitis, Wilson's disease, chronic viral hepatitis, cirrhosis of any etiology and histories of liver transplantation. 3. Liver disease acquired during pregnancy, especially viral hepatitis, drug-induced toxicity and hepatolithiasis. 4. Pregnancy-related liver diseases including hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, preeclampsia, HELLP syndrome and fatty liver of pregnancy. Severity ranges from absence of symptoms to acute liver failure and even death. Severe cases have significant morbidity and mortality for both mother and fetus. These cases require rapid evaluation, accurate diagnosis and appropriate management by a multidisciplinary team including high-risk obstetrics, hepatology, gastroenterology and interventional radiology. Availability of liver transplantation is also important for obtaining good outcomes.

A Comparable Study on Efficacy of Granisetron and Promethazine in Controlling Hyperemesis Gravidarum

Purpose: Hyperemesis gravidarum is one of the leading causes of hospitalization during pregnancy. This randomized study wasaimed to compare and evaluate the efficacy of granisetron and promethazine in controlling nausea and vomiting in pregnancy.Materials and Methods: This study was done in the Department of Obstetrics and Gynaecology, Nalanda Medical College andHospital, Patna, Bihar, over a period of 6 months from February 2019 to July 2019. The included patients were administeredgranisetron and promethazine randomly and evaluated for nausea and vomiting by senior gynecologist blinded to designated drugs.Results: This study showed that granisetron was more effective than promethazine in controlling nausea and vomiting inpregnant patients. Greater patient satisfaction and less adverse drug reaction were observed in women receiving granisetron.Conclusion: Hyperemesis gravidarum is a health-related problem with social, economic, and psychological dimensions.All efforts, especially simple outpatient strategies, can reduce the severity of this condition and will help pregnant women tocontinue her pregnancy with satisfaction.

Helicobacter pylori infection and hyperemesis gravidarum: a prospective pilot study in India

Background: About 80% of all pregnant women experience some form of nausea and vomiting during their pregnancy. Hyperemesis gravidarum, the commonest indication for admission to hospital in the first half of pregnancy affects approximately 0.3%-2.0% of pregnancies. Helicobacter pylori infection has been implicated in the cause of nausea and occasional vomiting in early pregnancy. The objectives of this study are to determine the proportion of H. pylori seropositivity among women with hyperemesis gravidarum (HG) and determine its relation with socio-economic status.Methods: This was a prospective study conducted in a tertiary hospital in Bangalore among 60 pregnant women with HG for a period of 12 months. Venous blood samples were obtained and serum IgG for H. pylori was measured using enzyme-linked immunosorbant assay (ELISA). Details regarding socioeconomic status, recurrence of symptoms and severity were noted.Results: The proportion of H. pylori seropositivity among pregnant women with hyperemesis in our study was 70%.There was a significant increase in severity and recurrence of vomiting among seropositive cases. Women belonging to rural areas had 1.17 times the risk of infection compared to women with urban area. We also found women belonging to the lower socioeconomic status had 0.52 times more risk to develop Helicobacter pylori infection.Conclusions: This study suggests that H. pylori is an independent risk factor for vomiting in pregnancy. Effective treatment and eradication of H pylori infection may help reduce severity and recurrence of vomiting among positive cases thus reducing its adverse consequences.

Hyperemesis Gravidarum, Wernicke’s Encephalopathy and Korsakoff Syndrome Looked through the Lens of Three Cases, Paper II

Objective: Pregnancy a normal physiological condition is worsened by morning sickness, nausea and vomiting of pregnancy, hyperemesis gravidarum, Wernicke’s encephalopathy and Korsakoff syndrome in vulnerable women with gestation. This report of three cases described hyperemesis gravidarum, Wernicke’s encephalopathy and Korsakoff syndrome in the worsening pregnancies.Methods:Prospective collection of data concerning three pregnant patients seen in Dubai Health Care City, Dubai, United Arab Emirates. Results:All three patients were admitted to the hospital with manifestations of HG and WE and one of them showed additional features of Korsakoff syndrome. One patient developed intractable hyponatremia and central pontine myelinolysis. Two patients developed abortion while one patient's pregnancy ended with successful delivery with living infant. All patients were managed with thiamine, antiemetics, parenteral fluids and electrolytes and one patients required steroid therapy. Conclusion:The findings of these cases are compatible with international literature on HG and its sequential syndromes. This study may enhance awareness of HG, WE and KS and also fill the knowledge gap of professionals providing services to women with worsening health during pregnancy in Arabian Gulf countries

Maternal and fetal outcomes in pregnant women with hyperemesis gravidarum

Background: Hyperemesis gravidarum (HG) is associated with maternal weight loss, nutritional deficiencies, fluid and electrolyte abnormalities, which may lead to adverse fetal and maternal outcomes. The purpose of this study was to evaluate the relationship of hyperemesis gravidarum to maternal and foetal outcomes.Methods: A hospital-based prospective observational study was carried out. All patients with singleton pregnancy diagnosed as / history of hyperemesis gravidarum the current pregnancy was included in the study. The pregnant women with multiple pregnancy, molar pregnancy, presence of pre-gestational diabetes, pre-gestational hypertension, and other causes of nausea such as appendicitis and pyelonephritis were excluded from the study.Results: 36 pregnant women with prevalence rate of 3.28% have been found to be suffering from HG. Almost half (17, 47.22%) of the pregnant women with HG had age less than 25 years. The significant association (p-value: 0.0099) has been found between parity and smoking with HG. HG was significantly associated with low birth weight (p-value: 0.0133); small for gestational age (SGA) (p-value: 0.0316); APGAR score < 7 after 1 minute (p-value: 0.0060); and APGAR score <7 after 5 minutes (p-value: 0.0006). There is no association found between mode of delivery, gestational diabetes, and pregnancy-induced hypertension with HG.Conclusions: HG can adversely affect fetal as well as maternal, though not significant, pregnancy outcomes.

Encefalopatía de Wernicke secundario a hiperémesis gravídica: la importancia del diagnóstico temprano / Wernicke encephalopathy secondary to hyperemesis gravidarum: importance of early diagnosis

RESUMEN Introducción: La hiperémesis gravídica (HG) es una condición frecuente en el embarazo, que puede resultar en complicaciones potencialmente letales como la encefalopatía de Wernicke (EW), síndrome que al ser reconocido y tratado tardíamente puede traducirse en una alta morbi-mortalidad materna y fetal. Objetivo: Describir el primer caso de EW secundario a HG en Colombia y realizar una revisión de la literatura publicada sobre su diagnóstico y tratamiento. Materiales y métodos: Se describe un caso de EW secundario a HG en el que se brindó un manejo interdisciplinario. Se realizó una revisión de la literatura con los términos "encefalopatía de Wernicke", "hiperémesis gravídica" y "embarazo" incluyendo reportes de casos, series de casos, artículos de revisión, investigaciones originales o cartas al editor en inglés, español y francés, en donde se analizaron el método y tiempo del diagnóstico, pauta de tratamiento y estado funcional final. Resultados: Se incluyeron 69 publicaciones y se identificaron 89 casos. En 23 de ellos se presentó pérdida gestacional, sólo en el 12,4% de los casos se reportó el nivel de tiamina, de los cuales en el 90% se encontraba disminuido y de los casos en donde se reportó estado funcional final en el 5,9% la gestante falleció. Conclusión: La EW secundaria a HG es una complicación potencialmente letal. Debe sospecharse ante cualquier alteración neurológica e historia de emesis persistente. El diagnóstico y tratamiento oportuno interdisciplinario son fundamentales para disminuir el riesgo de secuelas que limitan la capacidad funcional con alto impacto en la calidad de vida.

ABSTRACT Introduction: Hyperemesis gravidarum (HG) is a frequent condition in pregnancy, which can result in potentially lethal complications such as Wernicke encephalopathy (WE), a syndrome that can be translated into a high maternal and fetal morbidity and mortality if it is recognized and treated late. Objective: To describe the first case of WE due to HG in Colombia and to review the published literature about its diagnosis and treatment. Materials and methods: We describe a case of WE due to HG with an interdisciplinary approach. A review of the literature was performed with the terms "Wernicke's encephalopathy", "hyperemesis gravidarum" and "pregnancy" including case reports, case series, review articles, original investigations or letters to the editor in English, Spanish and French, where the method and time of the diagnosis, treatment regimen and sequelae were analyzed. Results: Sixty-nine publications were included and 89 cases were identified. In 23 of them had a gestational loss, only in 12.4% of the cases the thiamine level was reported, in which 90% was diminished and in the cases where the final functional status was reported in 5.9% of the pregnant woman died. Conclusion: WE due to HG is a potentially lethal complication. In any neurological disturbance and history of persistent emesis it should be suspected. Timely interdisciplinary diagnosis and treatment are essential to reduce the risk of sequelae that limit functional capacity with a high impact on quality of life.

Maconha e gravidez: síndrome da hiperêmese por canabinoide - Relato de caso / Marijuana and pregnancy: cannabis hyperemesis syndrome - Case report

RESUMO Os autores relatam um caso da enfermaria psiquiátrica do Hospital Geral Santa Casa de Misericórdia de Sorocaba-SP. Paciente gestante, de 19 anos, usuária crônica de maconha que apresenta náuseas e vômitos intensos não responsivos aos antieméticos, associados a dor abdominal, agitação psicomotora e hábito compulsivo de tomar banhos quentes para alívio dos sintomas, quadro que caracteriza a SHC. Trata-se de uma síndrome rara, com efeito paradoxalmente emetogênico da maconha. É subdiagnosticada e relacionada ao uso crônico e intenso de maconha. Destacamos que não foi encontrada descrição de caso na literatura brasileira. A conclusão deste relato reporta a importância do reconhecimento e categorização da síndrome e sua correlação com a dependência de maconha, pois o tratamento implica a suspensão do uso de maconha, tratamento da dependência, além da prevenção de suas complicações clínicas.

A patient, 19-year-old, pregnant woman, marijuana chronic user, presenting abdominal pain, psychomotor agitation, unmanageable nausea, severe vomiting, not responsive to antiemetic drugs, associated with compulsive hot water showering. Cannabinoid hyperemesis syndrome is sub-diagnosed and rare, characterized by those three symptoms: heavy marijuana use, vomiting and repeated hot showering. There is no prior report in Brazilian medical literature. This paper aims to emphasize the importance of recognizing and categorizing this syndrome and its correlation to marijuana use. Main treatment is supportive care, withdrawing substance and supportive carries to suspension of marijuana use as well as clinical complications prevention.

Therapeutic Observation of the Treatment of Hyperemesis Gravidarum Majorly with Intradermal Needle plus Acupressure / 上海针灸杂志

Objective To observe the clinical efficacy in the treatment of hyperemesis gravidarum predominantly with intradermal needle plus acupressure.Method Seventy-six patients with hyperemesis gravidarum were randomized into a treatment group and a control group, 38 cases each. The control group was intervened by conventional medication, while the treatment group was intervened by intradermal needle plus acupressure based on the medication. The hyperemesis gravidarum score, Nutritional Risk Screening (NRS)-2002, and levels of human chorionic gonadotropin (β-HCG) and motilin in serum were observed before and after the treatment. The 24-hour nausea and vomiting times, intake of staple and water, admission duration, negative rate of ketone body, incidence of adverse reactions and clinical efficacy were compared between the two groups.Result The total effective rate and recovery rate were respectively 89.5％ and 52.6％ in the treatment group versus 81.6％ and 28.9％ in the control group. There was a significant difference in the therapeutic efficacy between the two groups (P<0.05). The parameters were significantly changed after the treatment in both groups (P<0.05). After the intervention, there were significant differences in the parameters between the two groups (P<0.05). The 24-hour nausea and vomiting times, intake of staple and water, admission duration and negative rate of ketone body in the treatment group were significantly different from those in the control group (P<0.05). The incidence of adverse reactions in the treatment group was 7.9％ versus 26.3％ in the control group, and the difference was statistically significant (P<0.05). Conclusion Taken as the major intervention method, intradermal needle plus acupressure is effective for hyperemesis gravidarum, and it can improve the expressions ofβ-HCG and motilin in serum, and increase the negative rate of ketone body.
