Diabetic embryopathy: pathogenesis, prenatal diagnosis and prevention
Obstetrical & Gynecological Survey
|June 1, 1986
Insights
Infants born to diabetic mothers have a significantly higher risk of congenital anomalies. This review explores causes, prenatal diagnosis, and prevention strategies for these birth defects in diabetic pregnancies.
Area of Science:
- Reproductive Medicine
- Neonatology
- Medical Genetics
Background:
- Diabetic pregnancies show persistently elevated rates of congenital anomalies, 2-3 times higher than in non-diabetic cases.
- Congenital malformations account for approximately 40% of perinatal deaths in infants of diabetic mothers.
Purpose of the Study:
- To review the current understanding of congenital anomalies in infants of diabetic mothers.
- To discuss pathogenesis, diagnostic methods, and prevention strategies.
Main Methods:
- Review of human and experimental studies on diabetic embryopathy.
- Analysis of available prenatal diagnostic techniques.
- Synthesis of approaches for malformation prevention.
Main Results:
- Congenital anomalies remain a major concern in diabetic pregnancies despite management improvements.
- Pathogenesis involves complex interactions, with evidence from human and animal models.
- Prenatal diagnosis methods are available to detect potential malformations.
Conclusions:
- Preventing congenital malformations in infants of diabetic mothers requires a multi-faceted approach.
- Further research into pathogenesis and improved prenatal care are crucial.
- Early detection and intervention can potentially reduce the incidence and impact of these anomalies.
Abstract:
In spite of the overall improvement in the management of diabetic pregnancies, congenital anomalies among infants of diabetic mothers still remain two to three times higher than in the nondiabetic population. Approximately 40 per cent of all perinatal deaths among diabetic offspring are due to congenital malformations. This article reviews the subject and discusses current views on pathogenesis, based on human and experimental work, describes methods available for prenatal diagnosis, and suggests an approach to the possible prevention of these malformations.

01:22Diabetes 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...
01:20Pathophysiology 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, suggesting a...

01:26Diabetes Mellitus: Introduction
Diabetes mellitus consists of chronic metabolic disorders characterized by persistent hyperglycemia. This elevated blood glucose results from defects in insulin secretion, impaired insulin action, or both. Insulin, produced by pancreatic β-cells, is essential for maintaining glucose homeostasis by facilitating cellular glucose uptake for energy or storage. Disruptions in insulin production or function lead to glucose accumulation in the bloodstream, causing the clinical features and long-term...

Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
