Digital sclerosis in children with insulin-dependent diabetes mellitus
Insights
Children with insulin-dependent diabetes mellitus often develop digital sclerosis, characterized by skin thickening and joint contractures. This condition may serve as a model for studying microvascular complications and rheumatologic diseases.
Area of Science:
- Pediatric endocrinology
- Rheumatology
- Dermatology
Background:
- Insulin-dependent diabetes mellitus (IDDM) is a chronic condition affecting children.
- Musculoskeletal complications can arise in diabetic patients.
- Digital sclerosis, a skin condition affecting the fingers, has been observed in adults with diabetes.
Purpose of the Study:
- To investigate the prevalence of digital sclerosis in children with IDDM.
- To explore the association between digital sclerosis and microvascular complications.
- To evaluate the potential of childhood diabetic digital sclerosis as a model for rheumatologic research.
Main Methods:
- A cross-sectional study was conducted.
- 137 children diagnosed with IDDM were examined for skin changes and joint contractures.
- A control group of 52 healthy children was included for comparison.
Main Results:
- Palpable skin thickening and induration of the fingers were observed in 34% of children with IDDM, compared to 0% in controls.
- Mild flexion contractures of the interphalangeal joints were present in 19% of children with IDDM, particularly those with severe skin changes.
- The observed digital sclerosis shares clinical and pathogenic similarities with progressive systemic sclerosis.
Conclusions:
- Digital sclerosis is a prevalent finding in children with insulin-dependent diabetes mellitus.
- The presence of digital sclerosis and associated contractures may indicate microvascular involvement.
- Childhood diabetic digital sclerosis represents a valuable model for further rheumatologic investigation.
Abstract:
Palpable thickening and induration of the skin of the fingers were found in 47 (34%) of 137 children with insulin-dependent diabetes mellitus and in none of 52 normal children. Mild flexion contractures of the interphalangeal joints were seen in 26 (19%), mainly in those children with more extensive and severe skin changes. Such contractures have been linked to microvascular complications of diabetes. The clinical and pathogenic similarities to progressive systemic sclerosis make the digital sclerosis of childhood diabetes a promising model for further rheumatologic study.
