Insights

Maternal diabetes increases infant risk for congenital abnormalities, despite advances in pregnancy care. Achieving good glycemic control before conception is critical to prevent birth defects in infants of diabetic mothers.

Area of Science:

  • Endocrinology
  • Reproductive Medicine
  • Neonatology

Background:

  • Diabetes mellitus is a prevalent chronic disease globally.
  • Infants born to mothers with diabetes face a higher risk of congenital abnormalities.
  • Despite improved pregnancy care for diabetic women, the risk of birth defects persists.

Purpose of the Study:

  • To review congenital anomalies associated with maternal diabetes.
  • To highlight the importance of glycemic control in diabetic pregnancies.
  • To inform neonatal clinicians about diabetic embryopathy risks.

Main Methods:

  • Literature review of studies on maternal diabetes and congenital anomalies.
  • Analysis of mechanisms implicated in diabetic teratogenicity.
  • Discussion of clinical identification of at-risk infants.

Main Results:

  • Maternal diabetes is linked to a spectrum of fetal anomalies affecting multiple organ systems.
  • Teratogenic mechanisms of maternal diabetes are complex and multifactorial.
  • Good pre-conception glycemic control is essential for risk reduction.

Conclusions:

  • Congenital anomalies remain a significant concern for infants of diabetic mothers.
  • Early identification and management of diabetic embryopathy are crucial for neonatal clinicians.
  • Further research into prevention and treatment strategies is warranted.

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Glucose Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
