Summary Type 1 diabetes mellitus (T1DM) is a chronic disease characterized by autoimmune destruction of pancreatic beta cells and inadequate insulin production. Remission criteria in T1DM take into account serum levels of C-peptide and glycosylated hemoglobin, as well as the dose of insulin administered to the patient. However, remission of T1DM lasting longer than 1 year is rare. We describe here the cases of two young women who presented with positive glutamic acid decarboxylase (GAD) antibody and classic clinical manifestations of T1DM. Both patients had a prior history of Hashimoto’s thyroiditis. They were initially treated with a basal-bolus regimen of insulin (glargine and lispro/glulisine). Once their blood glucose levels were controlled, they were started on oral sitagliptin 100 mg and vitamin D3 5000 IU daily. After this therapy, both patients achieved clinical diabetes remission for 4 years, along with a decrease in anti-GAD antibody levels. These benefits were probably associated with immunological effects of these medications. Inhibition of dipeptidyl peptidase 4 (DPP-4) in animal models deregulates Th1 immune response, increases secretion of Th2 cytokines, activates CD4+CD25+FoxP3+ regulatory T-cells and prevents IL-17 production. Vitamin D3 also activates CD4+CD25+FoxP3+ regulatory T-cells, and these medications combined can improve the immune response in patients with new-onset T1DM and probably promote sustained clinical remission. Learning points: The use of sitagliptin and vitamin D3 in patients with new-onset type 1 diabetes mellitus (T1DM) may help decrease the daily insulin requirement by delaying beta cell loss and improving endogenous insulin production. The use of sitagliptin and vitamin D3 in new-onset T1DM could help regulate the imbalance between Th17 and Treg cells. Age 14 years or above, absence of ketoacidosis and positive C-peptide levels in patients with T1DM are good criteria to predict prolonged T1DM remission. The determination of anti-GAD antibodies and C-peptide levels could be helpful in the follow-up of patients in use of sitagliptin and vitamin D3, which could be associated with prolonged T1DM clinical remission.

Abstract Objective: Obesity was once a rare problem in Type 1 diabetes mellitus, but is a growing problem today. The aim of our study is to determine the frequency of overweight / obesity at the time of diagnosis and during follow-up in children with type 1 diabetes mellitus as well as review the conditions that may accompany. Methods: 315 patients with type 1 diabetes mellitus were retrospectively analyzed. The patients were divided into two groups according to the last examination as normal weight and overweight / obese. The two groups were compared in terms of age at diagnosis, gender, birth weight, family history, anthropometric measurements, insulin dose used and blood pressure measurements, and insulin, c-peptide, hemoglobin A1c, triglyceride, and high-density lipoprotein levels at the time of diagnosis and follow-up. Results: The prevalence of overweight / obese in all patients was 4.8% at the time of diagnosis, while it was 9.8% at the last examination. The height, weight and BMI SD scores and c-peptide levels at the time of diagnosis of the overweight / obese group were higher than those with normal weight (p <0.001 and p = 0.008, respectively). The frequency of dyslipidemia and hypertension was higher in the overweight / obese group than in the normal weight group [18.2% versus 5% (p = 0.015) and 10% versus 1.5% (p = 0.003), respectively]. Conclusion: In our study, the fact that the overweight / obese group had higher BMI and c-peptide and lower HDL values at the time of diagnosis can be evaluated as indicators that insulin resistance syndrome can accompany T1DM from the beginning (double diabetes). When determining the treatment and follow-up strategies of patients with type 1 diabetes mellitus, considering the risk of obesity and taking the necessary precautions is very important in terms of morbidity.
