Elastic modulus in young diabetic patients (ultrasound measurements of pulse wave velocity)
Insights
Non-invasive Doppler C.W. effectively identifies pre-clinical arterial lesions in children with diabetes mellitus. Increased pulse wave velocity and arterial elastic modulus correlate with diabetes duration, highlighting early vascular changes.
Area of Science:
- Vascular Medicine
- Pediatric Endocrinology
- Medical Imaging
Background:
- Diabetes mellitus can lead to early arterial disease, even in children.
- Non-invasive methods are crucial for detecting pre-clinical vascular changes.
- Doppler Continuous Wave (C.W.) ultrasound offers a potential tool for arterial assessment.
Purpose of the Study:
- To validate non-invasive Doppler C.W. for evaluating arterial diseases in children.
- To assess the identification of pre-clinical arterial lesions using this method.
- To investigate arterial wall elasticity in diabetic children compared to healthy controls.
Main Methods:
- Study included 28 children with insulin-dependent diabetes mellitus and 28 healthy controls.
- Transit time methodology was used to determine the elastic modulus of lower limb arterial walls.
- Statistical analysis was applied to compare groups and identify correlations.
Main Results:
- An increased pulse wave velocity was observed in diabetic children.
- A significant correlation was found between the elastic modulus and the duration of diabetes.
- These findings suggest early arterial wall stiffening in pediatric diabetes.
Conclusions:
- Non-invasive Doppler C.W. is a valid method for assessing arterial health in diabetic children.
- Early detection of arterial lesions is possible, enabling timely intervention.
- The study highlights the impact of diabetes duration on arterial elasticity in pediatric patients.
Abstract:
Aim of this study is to confirm the validity of non-invasive evaluation with Doppler C.W. in the study of arterial diseases and in the identification of pre-clinical arterial lesions. We studied twenty-eight children suffering from diabetes mellitus, and dependent on insulin and a control group composed of twenty-eight healthy persons. All subjects were studied using the methodology of the transit time for the determination of the elastic modulus of the lower limb arterial wall and results were analysed according to a statistical method. Although the groups were small, an increase in pulse wave velocity was noted in diabetic children and a significative correlation was found between the elastic modulus and duration of diabetes.
