[Clinico-genealogical study of microcirculation in diabetes mellitus type 1]
Abstract:
Altogether 60 patients with type I diabetes mellitus and their 29 relatives were examined. Diabetic microangiopathies were diagnosed in 29 patients, in 31 they were not found. Among relatives of the 1st degree of relationship 16 persons were with type I diabetes mellitus with angiopathies, 13 persons without angiopathies. In the patients with microangiopathies a degree of platelet aggregation significantly exceeded a similar index in the patients without microangiopathies in all age groups. In the relatives of the patients with diabetes mellitus complicated by microangiopathies, a degree of platelet aggregation was significantly higher than that in the relatives of the patients with diabetes mellitus without microangiopathies. It suggests hereditary predisposition to the development of diabetic microangiopathies. In the patients with microangiopathies there was an increase in the level of pre-beta-fraction and a decrease in the level of alpha-fraction of lipoproteins suggesting interrelationship of rheological disorders and lipid metabolism.
Insights
Type I diabetes mellitus complications like microangiopathies show a hereditary predisposition, indicated by increased platelet aggregation in affected patients and their relatives. Lipid metabolism alterations also correlate with these microvascular issues.
Area of Science:
- Endocrinology
- Diabetology
- Vascular Biology
Context:
- Type I diabetes mellitus is a complex endocrine disorder.
- Diabetic microangiopathies represent significant long-term complications.
- Understanding genetic and metabolic factors is crucial for managing diabetes.
Purpose:
- To investigate the role of hereditary factors in diabetic microangiopathies.
- To assess platelet aggregation and lipoprotein profiles in patients with and without microangiopathies.
- To explore the relationship between rheological disorders and lipid metabolism in diabetes.
Summary:
- This study examined 60 patients with type I diabetes mellitus and 29 relatives, assessing for diabetic microangiopathies.
- Patients with microangiopathies exhibited significantly higher platelet aggregation compared to those without.
- Relatives of patients with microangiopathies also showed increased platelet aggregation, suggesting a hereditary predisposition.
- Elevated pre-beta-lipoprotein and decreased alpha-lipoprotein fractions were observed in patients with microangiopathies, indicating a link to lipid metabolism.
Impact:
- Findings suggest a genetic component contributing to the development of diabetic microangiopathies.
- Highlights the potential role of platelet hyperaggregability as a risk factor.
- Suggests a connection between dyslipidemia and microvascular complications in type I diabetes mellitus.
- Informs potential future research into targeted therapies for preventing or managing diabetic microangiopathies.
