ABSTRACT

OBJECTIVE: To evaluate the use of metformin for preventing cesarean deliveries and large-for-gestational-age (LGA) newborn (NB) outcomes in non-diabetic obese pregnant women. SUBJECTS AND METHODS: This is a randomized clinical trial with obese pregnant women, divided into 2 groups: metformin group and control group, with followed-up prenatal routine. The gestational age of participants was less than or equal to 20 weeks and were monitored throughout entire prenatal period. For outcomes of delivery and LGA newborns, absolute risk reduction (ARR) and the number needed to treat (NNT) were calculated with a 95% confidence interval (CI). RESULTS: 357 pregnant women were evaluated. From the metformin group (n = 171), 68 (39.8%) subjects underwent cesarean delivery, and 117 (62.9%) subjects from the control group (n = 186) had intercurrence (p < 0.01). As for the mothers' general characteristics, there was significance for marital status (p < 0.01). Maternal-fetal results presented reduced preeclampsia (p < 0,01). Primary prophylactic results presented an ARR of 23.1 times (95% CI: 13.0-33.4) with NNT of 4 (95% CI: 3.0-7.7) and no significant values for LGA NB (p > 0.01). Secondary prophylactic outcomes presented decreased odds ratio for preeclampsia (OR = 0.17, 95% CI: 0.10-0.41). CONCLUSION: The use of metformin reduced cesarean section rates, resulted in a small number of patients to be treated, but it did not reduce LGA NB. Administering a lower dosage of metformin from the early stages to the end of treatment may yield significant results with fewer side effects. Arch Endocrinol Metab. 2020;64(3):290-7.

ABSTRACT

Abstract Objectives: identify the action of metformin and physical activities to reduce weight gain and prevent mellitus diabetes in obese pregnant women. Methods: the electronic search was performed in PubMed / MEDLINE, LILACS, Web of Science, Scopus and Cochrane library databases between 2008 and 2018. The selection took place between April and July 2018, through the descriptors "pregnancy, obesity, metformin, treatment, exercise". A protocol was programmed and consecutively a selective research on the inclusion / exclusion phase. The "PICO" strategy was used. Population: obese pregnant women. Intervention: physical exercises and metformin. Control: The main indicator established was therapeutic outcomes with physical activity and metformin. Outcome of interest: body weight control. Results: by selecting the database, 3,983 articles were identified on the topic of interest. After selecting and eligibility, only 16 scientific studies were selected, of which 81.25% were clinical trials related to diet programs, physical activity, metformin use and possible outcomes, 18.75% were prospective cohort on causes of obesity in gestation and its association with gestational mellitus diabetes and preventive therapies. The study pointed out the possibility of adapting physical therapy programs with the correct metformin dosage for a greater control in gestational weight gain. However, there is a need for greater awareness and changes in habits for obese woman during the gestational period. Conclusions: the drug presents similarity to physical activity by activating AMPK and may be added to treatments that propose changes in pregnant women's lifestyle to reduce weight gain and prevent gestational diabetes mellitus with a better understanding of the optimal dosage. Thus, the study suggests the use of metformin is not only for the prevention and the intercurrence of gestational diabetes mellitus, but a strictly careful investigation allowing its use to non-diabetic obese pregnant women.


Resumo Objetivos: identificar a ação da metformina e da atividade física para redução do ganho de peso e prevenção do diabetes mellitus em gestantes obesas. Métodos: a busca eletrônica foi realizada nas bases de dados PubMed/MEDLINE, LILACS, Web of Science, Scopus e biblioteca Cochrane entre 2008 e 2018. A seleção ocorreu entre abril e julho de 2018, através dos descritores "gravidez, obesidade, metformina, tratamento, exercício". Programou-se um protocolo e consecutivamente uma etapa seletiva de inclusão/exclusão das pesquisas. Utilizou-se a estratégia "PICO". População: gestantes obesas. Intervenção: exercícios fisicos e metformina. Controle: o principal comparador estabelecido foi o desfecho terapêutico com atividade fisica e metformina. Desfecho de interesse: controle do peso corporal. Resultados: através da seleção do banco de dados, 3.983 artigos foram identificados sobre o tema de interesse. Após as etapas de seleção e elegibilidade, apenas 16 estudos científicos foram selecionados, dos quais 81,25% ensaios clinicos referentes aos programas de dieta, atividade física, uso da metformina e possíveis desfechos, 18,75% coorte prospectiva sobre as causas da obesidade na gestação e sua associação com o diabetes mellitus gestacional e terapêutica preventiva. O estudo apontou a possibilidade de se adequar programas de terapias físicas com a dosagem correta de metformina para um maior controle no ganho de peso gestacional. No entanto, existe a necessidade de uma maior concientização e mudanças de hábitos da mulher obesa durante o período gestacional. Conclusões: a droga apresenta semelhança com a atividade física ao ativar o AMPK e pode somar aos tratamentos que propõem mudanças no estilo de vida das gestantes para reduzir o ganho de peso e prevenir o diabetes mellitus gestacional com a necessidade de um melhor entendimento sobre a dosagem ideal. Desta forma, o estudo sugere que o uso da metformina não seja apenas para prevenção e intercorrências do DMG, mas também com uma investigação estritamente cuidadosa para possibilitar o seu uso em grávidas obesas não diabéticas.

ABSTRACT

Objetivos: o artigo objetiva avaliar o uso de metformina em gestantes obesas na prevenção da pré-eclâmpsia. Métodos: trata-se de um ensaio clínico randomizado com mulheres grávidas obesas com índice de massa corporal superior ou igual a 30 kg/m2 divididos em dois grupos ­ um grupo de estudo, que utilizou metformina, e um grupo controle, que seguiu a rotina de pré-natal. As gestantes entraram no estudo com idade gestacional menor que 20 semanas e foram acompanhadas durante todo o período pré-natal. O diagnóstico de pré-eclâmpsia foi feito de acordo com os critérios da Organização Mundial de Saúde. Resultados: verificou-se a redução de risco absoluto e o número necessário para tratar em um intervalo de confiança de 95% para o resultado pré-eclâmpsia. Nos resultados, 272 gestantes foram avaliadas. No grupo de estudo (n = 127), oito (6,3%) desenvolveram pré-eclâmpsia. No grupo controle (n = 145), 31 (21,4%) tiveram a doença (p <0,01). Conclusão: o estudo apontou uma redução de risco absoluto de 15,1 vezes (IC95%: 7,1-22,9) e número necessário para tratar de sete (IC95%: 4,4-13,9). O uso de 1000 miligramas diárias de metformina indicou uma redução de 15,1 vezes no risco absoluto de pré-eclâmpsia na população estudada, com a necessidade de tratar sete gestantes para evitar um desfecho.


Aims: The article aims to evaluate the use of metformin in obese pregnant women in the prevention of pre-eclampsia. Methods: This is a randomized clinical trial with obese pregnant women with a body mass index greater than or equal to 30 kg / m2 divided into two groups: a study group that used metformin and a control group that followed the prenatal routine. The pregnant women entered the study with gestational age less than 20 weeks and were followed throughout the prenatal period. The diagnosis of pre-eclampsia was made according to World Health Organization criteria. Results: The absolute risk reduction and number needed to treat in a 95% confidence interval for the preeclampsia result were checked. In the results, 272 pregnant women were evaluated. In the study group (n = 127) eight (6.3%) developed preeclampsia, in the control group (n = 145) 31 (21.4%) obtained the disease (p <0.01). Conclusions: The study indicated an absolute risk reduction of 15.1 times (95% CI: 7.1-22.9) and number needed to treat of 7 (95%CI: 4.4-13.9). The use of 1000 milligrams daily metformin indicated a 15.1 x reduction in the absolute risk of preeclampsia in the study population, with the need to treat seven pregnant women to avoid an outcome.

ABSTRACT

OBJECTIVE: To evaluate the factors associated with the need for insulin as a complementary treatment to metformin in pregnant women with gestational diabetes mellitus (GDM). METHODS: A case-control study was performed from April 2011 to February 2016 with pregnant women with GDM who needed complementary treatments besides diet and physical exercise. Those treated with metformin were compared with those who, in addition to metformin, also needed the combination with insulin. Maternal characteristics and glycemic control were evaluated. Multinomial logistic regression models were developed to evaluate the influence of different therapies on neonatal outcomes. RESULTS: A total of 475 pregnant women who needed pharmacological therapy were evaluated. Of these, 366 (77.05%) were submitted to single therapy with metformin, and 109 (22.94%) needed insulin as a complementary treatment. In the analysis of the odds ratio (OR), fasting glucose (FG) < 90 mg/dL reduced the odds of needing the combination (OR: 0.438 [0.235-0.815]; p = 0.009], as well as primiparity (OR: 0.280 [0.111-0.704]; p = 0.007]. In obese pregnant women, an increased chance of needing the combination was observed (OR: 2,072 [1,063-4,039]; p = 0,032). CONCLUSION: Obesity resulted in an increased chance of the mother needing insulin as a complementary treatment to metformin, while FG < 90 mg/dL and primiparity were protective factors.


OBJETIVO: Avaliar os fatores associados à necessidade de insulina como tratamento complementar à metformina em gestantes com diabetes mellitus gestacional (DMG). MéTODOS: Um estudo caso-controle foi realizado de abril de 2011 a fevereiro de 2016 com gestantes portadoras de DMG que necessitaram de tratamentos complementares além de dieta e exercícios físicos. Aquelas tratadas com metformina foram comparadas com aquelas que, além da metformina, também precisaram de combinação com insulina. Foram avaliadas as características maternas e de controle glicêmico. Modelos de regressão logística multinomial foram construídos para avaliar a influência das diferentes terapias nos desfechos neonatais. RESULTADOS: Foram avaliadas 475 gestantes que necessitaram de terapia farmacológica. Destas, 366 (77,05%) utilizaram terapia única com metformina, e 109 (22,95%) necessitaram de insulina como tratamento complementar. Na análise da razão de possibilidades (RP), a glicemia de jejum (GJ) < 90 mg/dL reduziu as chances de necessidade da combinação (RP: 0,438 [0,235­0,815]; p = 0,009), bem como a primiparidade (RP: 0,280 [0,111­0,704]; p = 0,007). Em gestantes obesas, foi observada uma chance maior de necessidade da combinação (RP: 2.072 [1.063­4.039]; p = 0,032). CONCLUSãO: A obesidade resultou em um aumento na chance de a mãe precisar de insulina como tratamento complementar à metformina, enquanto a GJ < 90 mg/dL e a primiparidade foram fatores de proteção.

ABSTRACT

The meningococcal disease manifestation associated with the presence of Cryptococcus neoformans is rare. There are no reports in the literature about these simultaneous infections in immunocompetent patients. The aim of the present study is to describe the first case of fulminant septic shock by Neisseira meningitidis associated with Cryptococcus neoformans coinfection in an immunocompetent patient. We describe a case of an immunocompetent 74-year-old Caucasian woman who presented with fulminant acute meningococcemia associated with cryptococcal meningitis, which progressed to worsening general condition and died of septic shock and multiple organ dysfunctions in less than 48 hours. This case report demonstrates the possibility of coinfections related to Neisseria meningitidis and Cryptococcus neoformans, even in immunocompetent patients, which represent a diagnostic challenge for clinicians, thus encouraging further studies for a better understanding.

ABSTRACT

Avaliar o tratamento utilizado e a classificação de peso de recém-nascidos (RN) de gestantes portadoras de Diabetes Mellitus Gestacional (DMG). Foi realizado um estudo transversal descritivo com gestantes portadoras de DMG, em gestação única, no período de abril de 2011 a fevereiro de 2016. Os dados avaliados foram o tipo de tratamento utilizado e a classificação de peso do RN. Foram avaliadas 893 gestantes. A dieta e a atividade física como única terapêutica foram utilizadas por 306 (34,3%), 366 (41%) necessitaram metformina, a associação de metformina e insulina foi necessária em 109 (12,2%) e utilizaram somente insulinoterapia 112 (12,5%) gestantes. Houve 27 (3,0%) RN pequenos para a idade gestacional (PIG), 687 (76,9%) RN adequados para a idade gestacional (AIG) e 179 (20,0%) RN grandes para a idade gestacional (GIG). A metformina foi a terapêutica mais utilizada e a maioria dos recém-nascidos foram AIG.


Evaluate the treatment used and the weight classification of newborns (NB) of pregnant women with Gestational Diabetes Mellitus (GDM). A descriptive cross-sectional study was developed with pregnant women with GDM in a single gestation from April, 2011 to February, 2016. The data evaluated were the type of treatment used and the weight classification of the newborn. A total of 893 pregnant women were evaluated. Dietary and physical activity as sole therapy was used by 306 (34,3%), 366 (41%) needed metformin, the combination of metformin and insulin was necessary in 109 (12,2%) and only used insulin therapy (12,5%) pregnant women. There were 27 (3,0%) small for gestational age NB (SGA), 687 (76,9%) adequate for gestational age NB (AGA) and 179 (20,0%) large for gestational age NB (LGA). Metformin was the most used therapy and most of the newborns were AIG.

ABSTRACT

Objetivo: Comparar os desfechos materno-fetais de gestantes com e sem diabetes mellitus gestacional (DMG). Metodologia: Foi realizado um estudo tipo transversal. O grupo de estudo foi composto por gestantes com diagnóstico de diabetes gestacional e início de tratamento entre 13 e 33 semanas de gestação atendidas de abril de 2011 a fevereiro de 2016, comparado a outro grupo de gestantes sem DMG atendidas de setembro de 2016 a fevereiro de 2017. Os desfechos primários avaliados foram presença de doença hipertensiva específica da gestação (DHEG), via de parto, presença de recém-nascido (RN) pequeno (PIG) e grande (GIG) para a idade gestacional, necessidade de unidade de terapia intensiva (UTI), Apgars baixos e óbito fetal. A análise estatística foi realizada através do cálculo de regressão logística multinomial, com nível de significância de 95% ajustado para fatores de confusão. Resultado: Foram avaliadas 663 gestantes portadoras de DMG e 1409 sem DMG. Após a análise de razão de chance, prematuridade (0,629 IC 95% 0,410-0,966) e presença de RNs PIG (0,345 IC 95% 0,200-0,596) diminuíram no grupo de diabéticas. Registrou-se um aumento da chance de nascimentos por cesariana (2,343 IC 95% 1,914-2,869) e de RNs GIG (1,969 IC 95% 1,397-2,773). Nas demais complicações na gravidez, não houve alteração (DHEG, óbito fetal, Apgars baixos e necessidade de UTI). Conclusão: O diagnóstico e o tratamento de DMG na assistência perinatal apresentam impacto positivo na redução de prematuridade e da presença de RNs PIG, entretanto, notou-se um aumento de nascimentos por cesariana e de RNs GIG.


Objective: To compare maternal and fetal outcomes of pregnant women with and without gestational diabetes mellitus (GDM). Methodology: A cross-sectional study was performed. The study group consisted of pregnant women diagnosed with gestational diabetes and onset of treatment between 13 and 33 weeks of gestation attended from April 2011 to February 2016, compared to another group of pregnant women without GDM attended from September 2016 to February 2017. The primary outcomes evaluated were the presence of specific hypertensive disease of gestation (SHGD), mode of delivery, presence of small (SGA) and large (LGA) newborns for gestational age, need for intensive care (ICU), low Apgars and fetal death. Statistical analysis was performed by calculating multinomial logistic regression, with a significance level of 95% adjusted for confounding factors. Results: 663 pregnant women with GDM and 1409 without GDM were evaluated. After the odds ratio analysis, prematurity (0.629 95% CI 0.410-0.966) and presence of SGA infants (0.345 95% CI 0.200-0.596) decreased in the diabetic group. There was an increased chance of cesarean births (2.343 95% CI 1.914-2.869) and GIG newborns (1.969 95% CI 1.397-2.773). In other pregnancy complications, there was no change (SHGD, fetal death, low Apgars and need for ICU). Conclusion: Diagnosis and treatment of GDM in perinatal care have a positive impact on reducing prematurity and the presence of SGA infants, however, there was an increase in cesarean births and LGA infants.

ABSTRACT

Abstract Objective Does the use of metformin have an influence on the outcomes of preeclampsia (PE)? Sources of Data The descriptors pregnancy, metformin, treatment, and preeclampsia associated with the Boolean operators AND and OR were found in the MEDLINE, LILACS, Embase and Cochrane databases. A flowchart with exclusion criteria and inclusion strategy using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, and eligibility criteria was used. Data were extracted regarding the type of study, the applied dosage, treatment time, segment, bias risks, and the Patient, Intervention, Comparison and Outcome (PICO) strategy to identify the quality of the study. Selection of Studies Total number of journals in the initial search (n= 824); exclusions from repeated articles on different search engines (n= 253); exclusions after reading the titles, when the title had no correlations with the proposed theme (n= 164); exclusions due to incompatibility with the criteria established in the methodological analysis (n= 185), exclusion of articles with lower correlation with the objective of the present study (n= 187); and final bibliographic selection (n= 35). Data Collection At first, a systematic review of the literature was performed. Subsequently, from the main selection, randomized and non-randomized trials with metformin that presented their results in absolute and relative numbers of PE outcomes were selected. The variables were treated statistically in the meta-analysis with the Review Manager software (RevMan), version 5.3. Copenhagen: Nordic Cochrane Centre, The Cochrane Collaboration. Denmark in the Hovedistaden region. Synthesis of Data The study showed that metmorfin presented greater preventive effects for pregnancy-induced hypertension and was less effective for PE. Conclusion Metformin may gain place in preventive treatments for PE, once the dosages, the gestational age, and treatment time are particularly evaluated. A methodological strategy with an improved perspective of innovative and/or carefully progressive dosages during pregnancy to avoid side effects and the possibility of maternal-fetal risks is suggested.


Resumo Objetivo O uso de metformina tem influência nos resultados da pré-eclâmpsia (PE)? Fontes de Dados Os descritores gravidez, metformina, tratamento e pré-eclâmpsia associados aos operadores booleanos AND e OR foram encontrados nas bases de dados MEDLINE, LILACS, Embase e Cochrane. Foi utilizado um fluxograma com critérios de exclusão e estratégia de inclusão, utilizando o protocolo Preferred Reporting Items for Systematic Reviews and Meta-Analyses PRISMA e critérios de elegibilidade. Os dados foram extraídos quanto ao tipo de estudo, dosagem aplicada, duração do tratamento, segmento, riscos de viés e estratégia Patient, Intervention, Comparison and Outcome (PICO) para identificar a qualidade do estudo. Seleção de Estudos Número total de periódicos na busca inicialmente realizada (n= 824); exclusões de artigos repetidos nos diferentes sites de busca (n= 253); exclusões após a leitura dos títulos, quando o titulo não apresentava correlações com o tema proposto (n= 164); exclusões por incompatibilidade com os critérios estabelecidos na análise metodológica (n= 185), exclusão de artigos com menor correlação com o objetivo do presente estudo (n= 187); e seleção bibliográfica final (n= 35). Coleta de Dados Inicialmente, foi realizada uma revisão sistemática da literatura. Posteriormente, a partir da seleção principal, foram selecionados estudos randomizados e não randomizados com metformina, os quais apresentaram em seus resultados números absolutos e relativos de desfechos de PE. As variáveis foram tratadas estatisticamente na metanálise por meio do Review Manager software (RevMan), version 5.3. Copenhagen: Nordic Cochrane Centre, The Cochrane Collaboration. Denmark in the Hovedistaden region. Síntese dos Dados O estudo demonstrou que a metmorfina apresenta maiores efeitos preventivos para a hipertensão induzida pela gravidez e é menos eficaz para a PE. Conclusão A metformina pode conquistar seu espaço nos tratamentos preventivos da PE, uma vez que as dosagens, a idade gestacional e o tempo de tratamento são particularmente avaliados. Sugere-se uma estratégia metodológica com uma perspectiva aprimorada de doses inovadoras e/ou cuidadosamente progressivas durante a gravidez, a fim de evitar efeitos colaterais e a possibilidade de riscos materno-fetais.

ABSTRACT

OBJECTIVE: To identify the changes caused by dyslipidemia and obesity in pregnancy suggesting causes for premature birth, and the prognosis for the newborn. METHOD: Systematic review based on the Medline, Lilacs, Embase and Cochrane library databases between 1996 and 2016. The search for studies included the following keywords: "dyslipidemia, pregnancy, obesity, preterm birth." A protocol was programmed and a protocol for inclusion/exclusion of studies was implemented. RESULTS: Of the 5,789 articles initially selected between March 1996 and July 2016, only 32 were in accordance with the established criteria. Of these, 28.12% discussed risk factors of prematurity; 37.50%, metabolic alterations and gestational dyslipidemia; 21.87%, dyslipidemic complications in preterm birth; and 12,50%, lipid metabolism, glycemic and placental transfer. CONCLUSION: There is a reduced adaptation of obese pregnant women to the metabolic changes of gestation. This favors dyslipidemic intercurrences in the mother, which, directly or indirectly, suggests the occurrence of premature births and high lipid transfer to the fetus. Therefore, preterm newborns, whose mothers were dyslipidemic during pregnancy, have greater risk of epicardial fat, both in early (first year of life) and in later (adult) phases of life.

ABSTRACT

OBJECTIVE: To assess the effectiveness of metformin in the incidence of gestational diabetes mellitus (GDM) in obese pregnant women attending a public maternity hospital in Joinville, Santa Catarina, Brazil. METHODS: Randomized clinical trial including obese pregnant women with a body mass index (BMI) ≥ 30 kg/m2, divided into two groups (control and metformin). Both groups received guidance regarding diet and physical exercise. The participants were assessed at two moments, the first at enrollment (gestational age ≤ 20) and the second at gestational weeks 24-28. The outcomes assessed were BMI and gestational diabetes mellitus (GDM) diagnosis. The data distribution was assessed with the Friedman test. For all the analytical models, the p-values were considered significant when lower than 0.05. The absolute risk reduction was also estimated. RESULTS: Overall, 164 pregnant women were assessed and further divided into 82 participants per group. No significant difference was observed in BMI variation between the control and metformin groups (0.9 ± 1.2 versus 1.0 ± 0.9, respectively, p = 0.63). Gestational diabetes mellitus was diagnosed in 15.9% (n = 13) of the patients allocated to the metformin group and 19.5% (n = 16) of those in the control group (p = 0.683). The absolute risk reduction was 3.6 (95% confidence interval 8.0-15.32) in the group treated with metformin, which was not significant. CONCLUSION: Metformin was not effective in reducing BMI and preventing GDM in obese pregnant women.


OBJETIVO: Avaliar a efetividade da metformina na incidência de diabetes mellitus gestacional (DMG) em gestantes obesas de uma maternidade pública de Joinville, Santa Catarina, Brasil. MéTODOS: Ensaio clínico randomizado desenvolvido com gestantes obesas com índice de massa corporal (IMC) ≥ 30 kg/m2, divididas em dois grupos (controle e metformina). Ambos os grupos receberam orientação sobre dieta e exercício físico. As participantes foram avaliadas em dois momentos, o primeiro na inclusão (com idade gestacional ≤ 20 semanas) e o segundo entre 24 e 28 semanas de gestação. Os desfechos avaliados foram IMC e diagnóstico de diabetes mellitus gestacional (DMG). A distribuição dos dados foi avaliada com o teste de Friedman. Para todos os modelos analíticos, foram considerados significativos os valores de p inferiores a 0,05. Foi estimada também a redução absoluta de risco. RESULTADOS: Foram avaliadas 164 gestantes, divididas em 82 participantes em cada grupo. Não houve diferença significativa na variação do IMC entre os grupos controle e metformina (0,9 ± 1,2 versus 1,0 ± 0,9, respectivamente, p = 0,63). O DMG foi diagnosticado em 15,9% (n = 13) das pacientes alocadas para o grupo metformina e 19,5% (n = 16) das incluídas no grupo controle (p = 0,683). A redução absoluta de risco foi de 3,6 (intervalo de confiança de 95% 8,0­15,32) no grupo metformina, o que não foi significativo. CONCLUSãO: A metformina não foi eficaz em reduzir o IMC e prevenir o DMG em gestantes obesas.

ABSTRACT

Summary Objective: To identify the changes caused by dyslipidemia and obesity in pregnancy suggesting causes for premature birth, and the prognosis for the newborn. Method: Systematic review based on the Medline, Lilacs, Embase and Cochrane library databases between 1996 and 2016. The search for studies included the following keywords: "dyslipidemia, pregnancy, obesity, preterm birth." A protocol was programmed and a protocol for inclusion/exclusion of studies was implemented. Results: Of the 5,789 articles initially selected between March 1996 and July 2016, only 32 were in accordance with the established criteria. Of these, 28.12% discussed risk factors of prematurity; 37.50%, metabolic alterations and gestational dyslipidemia; 21.87%, dyslipidemic complications in preterm birth; and 12,50%, lipid metabolism, glycemic and placental transfer. Conclusion: There is a reduced adaptation of obese pregnant women to the metabolic changes of gestation. This favors dyslipidemic intercurrences in the mother, which, directly or indirectly, suggests the occurrence of premature births and high lipid transfer to the fetus. Therefore, preterm newborns, whose mothers were dyslipidemic during pregnancy, have greater risk of epicardial fat, both in early (first year of life) and in later (adult) phases of life.


Resumo Objetivo: Identificar as alterações provocadas pela dislipidemia e pela obesidade na gestação que sugerem causas de partos prematuros e o prognóstico para o recém-nascido. Método: Revisão sistemática nas bases de dados Medline, Lilacs, Embase e da biblioteca Cochrane entre os anos de 1996 e 2016. O processo de seleção ocorreu a partir dos descritores dislipidemia, gravidez, obesidade, nascimento prematuro. Um protocolo foi programado, havendo uma etapa seletiva de inclusão/exclusão das pesquisas. Resultados: Dentre os 5.789 artigos inicialmente selecionados entre março e julho de 2016, somente 32 estavam de acordo com os critérios estabelecidos. Desses, 28,12% focavam nos fatores de risco da prematuridade; 37,50%, em alterações metabólicas e dislipidemia gestacional; 21,87%, em intercorrências dislipidêmicas no parto prematuro; 12,50%, em metabolismo lipídico, glicêmico e transferências pela placenta. Conclusão: Existe uma menor adaptação da gestante obesa às mudanças metabólicas da gestação, favorecendo intercorrências dislipidêmicas na mãe, o que, direta ou indiretamente, sugere a ocorrência de partos prematuros e uma elevada transferência de lipídios para o feto. Portanto, recém-nascidos prematuros de mães dislipidêmicas durante a gravidez apresentam maior risco de desenvolver gordura epicárdica tanto na fase precoce (primeiro ano de vida) quanto na tardia (vida adulta).

ABSTRACT

Quais são os resultados preponderantes com a administração do cloridrato de metformina no índice de massa corporal elevado da gestante e no peso do recém-nascido? Foi feita uma revisão sistemática da literatura selecionada entre os anos de 2000 a 2017 sobre a obesidade e os efeitos da terapia na gestação nas bases MEDLINE, LILACS, Embase e Cochrane. Analisou-se artigos disponíveis em meio eletrônico, publicados em português, espanhol e inglês. Dentre os 2.127 artigos inicialmente escolhidos, somente 29 estudos estavam dentro dos critérios estabelecidos. Os desfechos avaliados foram resultados da terapia metformina versus placebo, terapia metformina versus insulina e o impacto de diferentes dosagens de metformina utilizadas nas pesquisas. A medicação apresentou resultados relevantes na redução do peso da mãe, mas não o do recém-nascido. Novos estudos clínicos multicêntricos são necessários, bem como uma estratégia terapêutica inovadora quanto às dosagens do cloridrato de metformina durante os três trimestres da gravidez.


Which are the most predominant results with the administration of metformin hydrochloride in the high body mass index of the pregnant and in the newborn's weight? A systematic review of the literature choose from 2000 to 2017 on obesity and the effects of therapy on pregnancy in MEDLINE, LILACS, Embase and Cochrane databases was performed. Among the 2,127 papers initially chosen, only 29 studies presented the criteria established. The outcomes assessed were results of the metformin therapy versus placebo, metformin therapy versus insulin, and the impact of different dosages of metformin used in the researches. The drug presented relevant results in reducing the weight of the mother, but not the newborn. New multi-centre clinical studies are needed as well as an innovative therapeutic strategy regarding the dosages of metformin hydrochloride during the three quarters of pregnancy.
