[Type 2 diabetes and pregnancy: management from preconception to the postpartum]. / Diabète de type 2 et grossesse : prise en charge de la préconception au postpartum.

With the increasing prevalence of diabetes, we are more frequently confronted to treat pregnant women with pre-existing type 2 diabetes. Thereby, we need to take several factors into account such as glycemic control before and during pregnancy, comorbidities such as overweight/obesity and hypertension, as well as existing complications and the need for changes in diabetes treatment. Pregnancy leads to increased insulin requirements, particularly from the second trimester onwards. In this context, a healthy lifestyle and control of weight gain are also necessary. This article provides an overview of the interdisciplinary management of type 2 diabetes before and during pregnancy and in the postpartum period.

En raison de l'augmentation de la prévalence du diabète, nous sommes de plus en plus confrontés à des femmes enceintes avec un diabète de type 2 préexistant. Les défis sont le contrôle glycémique avant et durant la grossesse, les comorbidités telles que le surpoids/l'obésité et l'hypertension artérielle ainsi que les complications existantes et le besoin de changement de traitement du diabète. La grossesse entraîne une forte augmentation des besoins en insuline, en particulier à partir du deuxième trimestre. Dans ce contexte, une bonne hygiène de vie et le contrôle de la prise de poids sont également nécessaires. Cet article offre une vue d'ensemble de la prise en charge interdisciplinaire du diabète de type 2 pendant la grossesse, y compris les soins prénataux et la phase péripartum.

[The impact of gestational diabetes on the mother and her child: what strategies can we propose?] / Impact du diabète gestationnel sur la mère et l'enfant : quelles stratégies proposer ?

Gestational diabetes is often considered as a diagnosis that affects maternal and offspring health exclusively during pregnancy. However, we now know that there are also medium- and long-term risks beyond pregnancy for the mother and the child. Lifestyle changes have been proven to be effective, but they are still a major challenge for young women with no previous health problems and a busy schedule. However, it is also a time that can be seen as an opportunity to take care of one's health in a more global perspective including also transgenerational aspects. This article describes the medium- and long-term issues at stake, but above all the different ways to approach them.

Le diabète gestationnel (DG) reste souvent considéré comme un diagnostic qui n'impacte que le moment de la grossesse. Or, nous savons aujourd'hui qu'il représente aussi des risques au-delà de la grossesse, et ce pour la mère comme pour l'enfant, à moyen et long termes. Si les modifications du style de vie ont fait leurs preuves, elles restent néanmoins un enjeu de taille chez des jeunes femmes a priori sans antécédents de problèmes de santé et avec un emploi du temps bien chargé. Néanmoins, cette situation peut aussi être vue comme une opportunité de prendre soin de sa santé dans sa globalité et dans une perspective transgénérationnelle. Cet article s'attache à décrire les enjeux à moyen et long termes d'un DG mais surtout les moyens pour y faire face.

Reactive hypoglycaemia during the OGTT after gestational diabetes mellitus: Metabolic implications and evolution.

AIMS: Gestational diabetes (GDM) presents an increased cardio-metabolic risk and is diagnosed with an oral glucose tolerance test (OGTT). Reactive hypoglycaemia (RH) during the OGTT in pregnancy is associated with adverse outcomes. Although postpartum OGTT after GDM is recommended, the occurrence and implications of RH are unknown. We investigated the prevalence, metabolic implications and longitudinal evolution of RH at 6-8 weeks postpartum in women with a history of GDM. METHODS: Between 2011 and 2021, we consecutively followed 1237 women with previous GDM undergoing an OGTT at 6-8 weeks postpartum. RH was defined as 2-h glucose <3.9 mmoL/L after the OGTT. Metabolic outcomes were compared in women with and without RH (RH+/RH-). We also included a subcohort of 191 women with data on insulin sensitivity/secretion indices (MATSUDA, HOMA-IR, insulin-adjusted-secretion ISSI-2). RESULTS: The postpartum prevalence of RH was 12%. RH+ women had a more favourable metabolic profile including a 2-5-times lower prevalence of glucose intolerance and metabolic syndrome at 6-8 weeks postpartum compared to RH- (all p ≤ 0.034). In the subcohort, women with RH+ had higher insulin sensitivity, higher ISSI-2 and an earlier glucose peak after OGTT (p ≤ 0.049) compared to RH- women at the same time point. Insulin resistance increased and ISSI-2 decreased over the first year postpartum in both groups. These changes were associated with a 50% reduction in overall RH prevalence at 1-year postpartum. Some of the favourable profiles of RH+ persisted at 1-year postpartum, without group differences in the longitudinal metabolic changes. CONCLUSIONS: At 6-8 weeks postpartum, RH was frequent in women after GDM and associated with a better metabolic profile including increased insulin sensitivity and higher insulin-adjusted-secretory capacity. RH might be a marker of favourable metabolic prognosis in women with a history of GDM.

[What is the place of a low carbohydrate or low glycemic index diet in gestational diabetes treatment?] / Quelle place pour une alimentation low-carb ou à index glycémique bas dans le diabète gestationnel ?

There is no real consensus on the ideal nutritional approach to recommend for gestational diabetes (GDM) treatment. A carbohydrates reduction (low-carb) is frequently suggested, although many studies have not found any consistent beneficial effects. On the other hand, according to recent meta-analyses, a low glycemic index (GI) diet would have favorable effects for the mother and the child. Although the clinical and practical value of GI is still being studied, a low GI diet seems to be the most appropriate approach in GDM. In addition, soluble fibers may have a beneficial metabolic impact in the short time of pregnancy. More evidence on the impact of these nutritional approaches in the short and long term for mother and child is needed.

Il n'y a pas de réel consensus concernant l'approche nutritionnelle idéale à recommander en cas de diabète gestationnel (DG). Une réduction des quantités de glucides (low-carb) est fréquemment mise en avant, alors que de nombreuses études n'y retrouvent pas d'effets bénéfiques notables. Toutefois, selon des méta-analyses récentes, une alimentation à index glycémique (IG) bas a des effets bénéfiques pour la mère et l'enfant. Même si la valeur clinique et pratique de l'IG fait encore l'objet d'études, cela semble être l'approche la plus appropriée en cas de DG. En complément, les fibres dites « solubles ¼ pourraient avoir un impact métabolique favorable dans le court délai imparti par la grossesse. Plus d'évidences sur l'impact de ces approches nutritionnelles à court et à long termes pour la mère et l'enfant sont indispensables.

[Insulin pump treatment: For whom and how to set it up on an outpatient?] / Traitement par pompe à insuline : pour qui et comment le mettre en place en ambulatoire ?

Pump therapy has existed for over 40 years and provides a more flexible delivery of insulin. To date, almost 25% of type 1 diabetic patients have chosen this therapeutic option. In recent years, it has also been offered to patients with type 2 insulin-requiring diabetes. The choice of insulin pump is based on its indication, the patient's preference, lifestyle and knowledge of the disease. A risk of developing ketoacidosis in case of interruption of insulin delivery exists. Its implementation therefore requires a specialized interdisciplinary care team available in case of emergency.

L'insulinothérapie par pompe existe depuis plus de 40 ans et permet une délivrance plus flexible de l'insuline. À ce jour, près de 25% des patients diabétiques de type 1 ont choisi cette option thérapeutique. Depuis quelques années, elle est aussi proposée aux patients diabétiques de type 2 insulino-requérants. Le choix de la pompe à insuline repose sur son indication, la préférence du patient, son style de vie et ses connaissances de la maladie. Un risque de survenue d'acidocétose en cas d'interruption de la délivrance d'insuline existe. Sa mise en place nécessite donc une équipe de soins interdisciplinaire spécialisée et disponible en cas d'urgence.

[Preconception care in patients with diabetes]. / Prise en charge préconceptionnelle chez une patiente avec un diabète préexistant.

In patients with diabetes, pregnancy is associated with high maternal and fetal risks, especially in unplanned pregnancies. Current evidence confirms that timely family planning and interdisciplinary care and management starting at the preconceptional period can optimize metabolic control and significantly reduce these risks. The purpose of this article is to summarize the different aspects to consider as well as provide tools to use when preparing patients with diabetes for a pregnancy.

Chez les patientes diabétiques, la grossesse est associée à des hauts risques materno-fœtaux, notamment lorsqu'elle n'est pas planifiée. L'évidence actuelle confirme que la planification familiale opportune ainsi qu'une prise en charge interdisciplinaire depuis la période préconceptionnelle permettent d'optimiser le contrôle métabolique et de diminuer ces risques de façon significative. Le but de cet article est de résumer les différents aspects à considérer ainsi que de fournir des outils à utiliser lors de la préparation des patientes avec un diabète à une grossesse.

[Type 1 diabetes, physical activity and novel technology]. / Diabète de type 1, activité physique et nouvelles technologies.

Physical activity is recommended for all patients with diabetes, but it is important to be particularly attentive in patients with type 1 diabetes. Because of their treatment, these patients have a higher risk of hypoglycemia. The challenge for both caregivers and the patient is to find the best possible strategy to practice the desired physical activity without any significant hypo- or hyperglycemia. Thus, an adaptation of the insulin and/or nutritional treatment is necessary, depending on the type, intensity and duration of the physical activity. Moreover, many technological devices are now available that can improve patient care, but they also have some limitations to take into account. Allover, an interdisciplinary approach is highly recommended, both for a specific or a regular physical activity practice.

L'activité physique est recommandée pour tous les patients avec un diabète, mais une attention particulière est nécessaire en cas de diabète de type 1. En effet, ces patients sont à haut risque d'hypoglycémie. Le défi des soignants et du patient est donc de trouver la meilleure stratégie possible pour pouvoir pratiquer l'activité physique souhaitée, et cela sans faire d'hypo ou d'hyperglycémie. Une adaptation du traitement d'insuline et/ou de l'alimentation est nécessaire, en fonction du type, de l'intensité et de la durée de l'activité physique. Il existe désormais plusieurs outils technologiques permettant d'améliorer la prise en charge du patient, lesquels ont également des limitations. Ainsi, une prise en charge interdisciplinaire diabétologique est recommandée en vue de la pratique d'une activité physique régulière ou ponctuelle.

[Value of continuous glucose monitoring in type 2 diabetic patients]. / Utilité de la mesure en continu de la glycémie chez les patients diabétiques de type 2.

Management of type 1 and type 2 diabetes mellitus is getting complex with the apparition of new treatments, but also new technologies. Among these, continuous glucose monitoring systems (CGMS) lead to a better glycemic control and less hypoglycemia in type 1 diabetic patients. Studies are scarce in type 2 diabetes but also seem to show a benefit, particularly in patients using insulin. Nevertheless, type 2 diabetic patients taking advantage of CGMS must be better defined. In any case, a multidisciplinary approach to the use of CGMS and interpretation of data is warranted.

La prise en charge du diabète, que ce soit de type 1 ou de type 2, ne cesse de se complexifier avec l'apparition de nouveaux traitements, mais aussi de nouveaux outils technologiques. Parmi ces derniers, les appareils mesurant la glycémie en continu permettent d'améliorer le contrôle glycémique et diminuent le risque d'hypoglycémie chez les patients diabétiques de type 1. Chez les patients diabétiques de type 2, les études sont moins nombreuses mais semblent aussi montrer un bénéfice, notamment chez les patients traités par insuline. Il convient cependant de bien définir quels patients diabétiques de type 2 seront de bons candidats au CGMS (continuous glucose monitoring system). Dans tous les cas, une prise en charge multidisciplinaire est nécessaire pour la pose de l'appareil et l'interprétation des tracés.

Cardio-Metabolic and Mental Health Outcomes Before and During the COVID-19 Pandemic in a Cohort of Women With Gestational Diabetes Mellitus in Switzerland.

Background: The COVID-19 pandemic has been associated with worsened metabolic and mental health in the general and perinatal population. The postpartum is a critical moment regarding these outcomes particularly in women with gestational diabetes mellitus (GDM). We investigated the cardio-metabolic and mental health outcomes before and during the pandemic in this population. Methods: This cohort study included 418 women with GDM, recruited during two distinct periods. This included 180 women exposed to the pandemic (E+) and recruited between May 2020-April 2021 and 238 women who were not exposed to the pandemic during their postpartum period (attended a year before=non-exposed (E-)) and recruited between January-December 2019. Among the E+, a nested-subcohort of 120 women were exposed both during pregnancy and postpartum. During the pandemic, we adopted a hybrid follow-up of women that consisted of in-person consultations, regular contact via phone calls (35%), sent recorded exercise guide to patients to follow at home and linked to our website. We specifically focused on maintaining motivation and keeping a strong focus on healthy lifestyle behaviors. Obstetric, neonatal, cardio-metabolic and mental health outcomes were assessed during pregnancy and postpartum. Results: The pandemic was not associated with worsened weight, weight retention, glucose tolerance, metabolic syndrome, well-being or depression in the postpartum with the exception of a minimally increased HbA1c, diastolic blood pressure and lower emotional eating scores in E+ women (all p ≤ 0.046). In the nested subcohort, E+ women had a slightly increased HbA1c at the first GDM visit and a higher need for glucose-lowering medication (both p ≤ 0.014), but HbA1c at the end of pregnancy and other cardio-metabolic, mental health, obstetric and neonatal outcomes during pregnancy were similar. Conclusions: The pandemic was not associated with any clinically relevant worsening of cardio-metabolic, mental health, obstetrical and neonatal outcomes in our GDM cohort. This was possibly due to a continued hybrid follow-up, and the partial lockdown in Switzerland.
