Insights
Thrombocyte spreading increased in older individuals and diabetics, correlating with retinopathy severity. This suggests impaired metabolic and vascular health in diabetes mellitus.
Area of Science:
- Biomedical Science
- Hematology
- Diabetology
Context:
- Investigated thrombocyte spreading in 162 individuals, including healthy controls and patients with type I and type II diabetes.
- Analyzed the influence of age, sex, retinopathy severity, disease duration, blood sugar, and HbA1 concentration on thrombocyte spreading.
Purpose:
- To examine the relationship between thrombocyte spreading and diabetes mellitus, considering various clinical factors.
- To determine if altered thrombocyte spreading is associated with diabetic complications like retinopathy.
Summary:
- Increased thrombocyte spreading was observed in older individuals and in both types of diabetics.
- A strong correlation was found between the extent of retinopathy and the prevalence of spread thrombocyte forms.
- Elevated thrombocyte spreading capacity may indicate a compromised metabolic and vascular state in diabetes mellitus.
Impact:
- Highlights a potential biomarker for metabolic and vascular disturbances in diabetes.
- Suggests that thrombocyte behavior could be a factor in the pathogenesis of diabetic retinopathy.
- Provides insights into the systemic vascular effects of diabetes mellitus.
Abstract:
In 162 test persons divided into healthy control persons and diabetics of type I and type II the thrombocyte spreading was investigated according to the method of Breddin. Age, sex, degree of seriousness of retinopathy, duration of diseases, present level of blood sugar and HbA1 concentration were taken into account. Spread thrombocyte forms were increasingly found in old age, in diabetics of both types and a close relation to the extent of retinopathy was evident. As diabetic retinopathy became evident and with growing degree of seriousness, spread forms of thrombocytes were increasingly found, so that the increased spreading capacity may be interpreted as a disturbed metabolic and blood vessel situation in diabetes mellitus.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Pathophysiology of 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...
