Insights
Pediatric diabetes is not rare, especially in very young children, and is linked to severe insulin deficiency. Early diagnosis and prompt management are crucial for better outcomes in children with diabetes.
Area of Science:
- Pediatrics
- Endocrinology
- Immunology
Background:
- Type 1 diabetes (T1D) incidence and presentation vary by age.
- Understanding T1D in young children is critical for early detection and management.
Purpose of the Study:
- To analyze the clinical characteristics and outcomes of newly diagnosed diabetic children.
- To identify factors associated with severe diabetic ketoacidosis (DKA) in pediatric diabetes.
Main Methods:
- Retrospective analysis of clinical and laboratory data from 165 newly diagnosed diabetic children.
- Age-stratified analysis and comparison of clinical features between severe and mild DKA groups.
Main Results:
- Common symptoms include polydipsia, weight loss, polyuria, and fatigue.
- Very young children (<2 years) showed higher dyspnea, lower C-peptide and HbA1c levels.
- Severe DKA was associated with younger age, preceding febrile illness, lower thyroid hormone levels, and higher white blood cell counts.
Conclusions:
- Diabetes in very young children is common and indicates more severe insulin deficiency.
- Young age and febrile illness may precipitate severe DKA in children.
- Prompt diagnosis and management are essential for pediatric diabetes.
Abstract:
Clinical and laboratory data of 165 newly diagnosed diabetic children at Chang Gung Children's Hospital in Taiwan from 1993 to 2003 were analyzed. The age distribution was categorized as 0-1 years: 19 (11.5%), 2-4 years: 39 (23.6%), 5-9 years: 61 (37%), and 10-16 years: 46 (27.9%); the incidence showed spring/winter peak and a mid-summer trough but not statistically significant (chi2= 1.86, p=0.61). The most common symptoms on presentation were polydipsia, weight loss, polyuria, and fatigue. Very young diabetic children had a higher incidence of having dyspnea at presentation (p=0.029) and had significantly lower levels of C-peptide (p=0.0086) and HbA1c (p=0.0025). The prevalences of GAD antibody and insulin autoantibodies were 67% and 49%, respectively. Children with severe diabetic ketoacidosis (DKA) were younger at diabetes onset (p=0.36, not to the statistical significance), had a higher incidence of preceding febrile illnesses (p=0.05), lower T4 and T3 levels (p=0.0008, 0.02), and higher white blood cell counts (p=0.03) than the mild group. In conclusion, diabetes in very young children is not rare and is more associated with more severe insulin deficiency. Young age at diabetes onset and preceding febrile illness may provoke severe DKA. High alertness is necessary for prompt diagnosis and management.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
