The use of insulin detemir during pregnancy: a safety evaluation

American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update

OBJECTIVE

The objective of this clinical practice guideline is to provide updated and new evidence-based recommendations for the comprehensive care of persons with diabetes mellitus to clinicians, diabetes-care teams, other health care professionals and stakeholders, and individuals with diabetes and their caregivers.

METHODS

The American Association of Clinical Endocrinology selected a task force of medical experts and staff who updated and assessed clinical questions and recommendations from the prior 2015 version of this guideline and conducted literature searches for relevant scientific papers published from January 1, 2015, through May 15, 2022. Selected studies from results of literature searches composed the evidence base to update 2015 recommendations as well as to develop new recommendations based on review of clinical evidence, current practice, expertise, and consensus, according to established American Association of Clinical Endocrinology protocol for guideline development.

RESULTS

This guideline includes 170 updated and new evidence-based clinical practice recommendations for the comprehensive care of persons with diabetes. Recommendations are divided into four sections: (1) screening, diagnosis, glycemic targets, and glycemic monitoring; (2) comorbidities and complications, including obesity and management with lifestyle, nutrition, and bariatric surgery, hypertension, dyslipidemia, retinopathy, neuropathy, diabetic kidney disease, and cardiovascular disease; (3) management of prediabetes, type 2 diabetes with antihyperglycemic pharmacotherapy and glycemic targets, type 1 diabetes with insulin therapy, hypoglycemia, hospitalized persons, and women with diabetes in pregnancy; (4) education and new topics regarding diabetes and infertility, nutritional supplements, secondary diabetes, social determinants of health, and virtual care, as well as updated recommendations on cancer risk, nonpharmacologic components of pediatric care plans, depression, education and team approach, occupational risk, role of sleep medicine, and vaccinations in persons with diabetes.

CONCLUSIONS

This updated clinical practice guideline provides evidence-based recommendations to assist with person-centered, team-based clinical decision-making to improve the care of persons with diabetes mellitus.

Maternal diabetes negatively impacts fetal health

Diabetes is a chronic metabolic disease affecting an increasing number of people. Although diabetes has negative health outcomes for diagnosed individuals, a population at particular risk are pregnant women, as diabetes impacts not only a pregnant woman's health but that of her child. In this review, we cover the current knowledge and unanswered questions on diabetes affecting an expectant mother, focusing on maternal and fetal outcomes.

Updates in Gestational Diabetes Prevalence, Treatment, and Health Policy

PURPOSE OF REVIEW

Gestational diabetes (GDM) is associated with adverse pregnancy and neonatal outcomes and increased maternal risk for subsequent type 2 diabetes. The best diagnostic strategy for GDM is debated and the role of oral antidiabetic medications (OAD) for treatment is unclear. In this paper, we review methods of GDM diagnosis, updates in GDM therapy, and interventions to reduce future type 2 diabetes in women with a history of GDM.

RECENT FINDINGS

A "one-step" screening protocol for GDM using 75-g, 2-h oral glucose tolerance testing at 24-28 weeks gestation is recommended by the International Association of the Diabetes and Pregnancy Study Groups, the American Diabetes Association, and the Endocrine Society. This strategy identifies a milder degree of hyperglycemia and thus increases GDM prevalence. Studies indicate that in these cases of mild hyperglycemia, treatment decreases pregnancy and neonatal complications. Insulin analogues including detemir, aspart, and lispro have been shown to be safe in pregnancy with a pregnancy category B classification. Growing literature suggests that sulfonylureas cross the placenta and are associated with increased incidence of macrosomia and neonatal hypoglycemia. Telephone or online diabetes prevention program (DPP)-based interventions for women with GDM have shown encouraging results in pilot studies. Insurance coverage remains a barrier. Additional studies are needed to determine the safety of OAD in pregnancy. Public policy supporting DPP could help improve patient access to these proven interventions.

Pharmacotherapy for hyperglycemia in pregnancy - The new insulins

Hyperglycemia in pregnancy may lead to adverse maternal, fetal and neonatal outcomes. Tight glycemic control is prudent in order to reduce pregnancy complications. For many years, the gold standard pharmacological therapy during pregnancy was human insulin. Recently, insulin analogues were also introduced to clinical use in pregnancy. This brief review aims to summarize the information on the efficacy and safety of insulin analogue therapy during gestation. The strengths and pitfalls of insulin analogue administration during gestation, compared with human insulin, are presented. According to studies in pregnant women with type 1 diabetes, insulins lispro, aspart and detemir are efficacious and safe. Correspondingly, the FDA has reclassified them for the treatment of pregnant women with diabetes from category C to category B. Although large and prospective data on insulin glargine in gestation are still lacking, no major safety concerns were documented. No controlled trials with insulins glulisine and degludec were conducted in pregnancy. In sum, insulin analogues are practical therapeutic options for hyperglycemia in pregnancy, mainly due to their hypoglycemia risk reduction. More research for their use in pregnant women with gestational diabetes or type 2 diabetes should be conducted. Overall, their efficacy and safety is possibly comparable to human insulin.

ACOG Practice Bulletin No. 190: Gestational Diabetes Mellitus

Gestational diabetes mellitus (GDM) is one of the most common medical complications of pregnancy. However, debate continues to surround the diagnosis and treatment of GDM despite several recent large-scale studies addressing these issues. The purposes of this document are the following: 1) provide a brief overview of the understanding of GDM, 2) review management guidelines that have been validated by appropriately conducted clinical research, and 3) identify gaps in current knowledge toward which future research can be directed.

Pharmacotherapy for gestational diabetes

INTRODUCTION

Gestational diabetes mellitus (GDM) represents impaired carbohydrate metabolism during pregnancy and is characterized by progressive insulin resistance and compensatory hyperinsulinaemia. If inadequately treated, it may lead to fetal macrosomia and other adverse outcomes.

AREAS COVERED

In this review, the authors summarize the current evidence from studies on the use of insulin and other agents for the treatment of women with GDM.

EXPERT OPINION

Lifestyle management is of paramount importance for the treatment of GDM. In pharmacotherapy, insulin remains the long-established mainstay of treatment. NPH (Neutral Protamine Hagedorn) and soluble human insulin have long been established for use, but favorable experience has now also accumulated with the newer insulins (aspart, lispro, detemir). Alternatively, metformin and glyburide have been used in GDM, but they have never gained wide acceptance. Nutritional supplements based on micronutrients and bioactives (probiotics and myoinositol) have shown promising results as well. Further experience with incretin agents (DPP-4 inhibitors and GLP-1 receptor agonists) is awaited.

Moieties in antidiabetic drugs as a target of insulin receptors in association with common neurological disorders

Insulin is a peptide that can be harmful with regards to neuroplasticity, neuroprotection and neuromodulation. Furthermore, the role of insulin highlights its relevance in the progress of diverse clinical disorders as well as in the mechanisms associated with certain pathogenesis and their evolution towards diabetes, obesity and neurodegenerative diseases. The precise molecular mechanisms by which these diseases are induced remain to be elucidated. The benefits in knowing/discovering these mechanisms in animal models and humans cannot be undermined. An in depth understanding of the principal risk factors leading to obesity and their management is vital in the implementation of early-life strategies of intervention and prevention, with a view to avoid adverse late-life outcomes. Therefore, the aim of the present study was to review their possible association with antidiabetic drugs.
