RESUMO
Objectives: Type 1 diabetes mellitus is a chronic autoimmune disease caused by insufficient production of insulin. Many studies have linked type 1 diabetes mellitus to vitamin D3 deficiency. We investigated the prevalence of vitamin D deficiency in Sudanese children and adolescents with type 1 diabetes mellitus and assessed the impact of vitamin D deficiency treatment on their glycemic control. Methods: In 2019-2022, we conducted a quasi-experimental study on 115 children with type 1 diabetes mellitus (1-19 years old) at the Sudan Childhood Diabetes Center. Vitamin D supplements were given orally to deficient patients for 3 months. The concentrations of hemoglobin A1c, fasting blood glucose, insulin dosage, and vitamin D (25-hydroxyvitamin D (25(OH)D)) were measured before and after vitamin D3 administration. One-way ANOVA and paired sample t-tests were used to evaluate the effect of supplementation. Results: Only 27% of type 1 diabetes mellitus children were deficient in vitamin D, whereas 31.1% were inadequate and 40.9% were sufficient. The administration of vitamin D supplements slightly improved hemoglobin A1c levels in 67.7% of the patients, but the difference was not significant (mean 10.8 ± 2.1% before, 10.1 ± 2.5% after, p0.05 = 0.199). However, there was a significant decrease in the fasting blood glucose level (mean: 174.978.5-136.759.1 ng/ml; p0.05 = 0.049). Vitamin D levels were significantly increased after treatment (mean = 49.6 ng/mL; t-test = -11.6, 95% CI 40.8-(-28.6); p0.05 = 0.000). After vitamin D3 supplementation, 25.8% of individuals changed their insulin dosage; however, there was no significant variation in insulin needs. Conclusions: The prevalence of vitamin D deficiency in children and adolescents with type 1 diabetes mellitus in Sudan is relatively high; incorporating vitamin D supplements in their treatment plan may improve their glycemic control.
RESUMO
Corona Virus Disease-2019 (COVID-19) is a novel pandemic disease. There have been many challenges for diabetic patients, which might have resulted in an increased risk of complications and significant lifestyle changes, including physical inactivity and psychological distress. This study evaluated the effects of lockdown on paediatric patients with type 1 diabetic mellitus (T1DM) in terms of acute metabolic complications and psychological deterioration. A questionnaire-based cross-sectional study was conducted between November 2020 and February 2021 at Mohammed Alamin Hamid Diabetic Clinic, Omdurman, Sudan. Data was collected from direct interviews with patients and their caregivers. Out of 208 children with T1DM aged from 1-18 years, 48.1% had persistent hyperglycaemia, and 20.6% had hypoglycaemia. Insulin doses were missed in 20.2% of them, glucose monitoring was not done in 28.8%, and 20.6% reported decreased physical activity during the lockdown. Mean HbA1c levels were the same in pre and post-lockdown periods. There was an insignificant relationship between physical activity, dietary changes, and glycaemic control (p values = 0.519 and 0.146, respectively). On the other hand, there was a significant weak positive correlation between psychological and behavioural disorders such as aggression, anxiety, isolation, and glycaemic control (p-value = 0.032, 0.002, and <0.0001; r = 0.115, 0.135, and 0.169, respectively). The negative impact of the COVID-19 lockdown found on blood glucose measures and psychological status may correlate with glucose monitoring equipment shortage, lifestyle changes, and mood deterioration.
