Objective: To compare continuous subcutaneous insulin infusion (CSII) therapy with multiple daily insulin (MDI) therapy on metabolic control in children and adolescents with type I diabetes mellitus (T1DM) over the long term. Methods: Fifty-two T1DM patients treated with CSII and monitored for at least one year prior to and at least five years following CSII were included. Thirty-eight age and sex-matched MDI controls with a 5-year follow up were recruited. Results: Mean age of the subjects, duration of diabetes and CSII therapy were 17.0 +/- 4.8 years, 10.7 +/- 2.8 years and 7.7 +/- 1.5 years respectively. Mean hemoglobin A1c (HbA I c) in the year prior to CSII, during the first year of treatment and after 5 years of CSII were 7.3 +/- 1 % (56 mmol/mol), 7.0 +/- 0.7% (53 mmol/mol) and 7.8 +/- 1.3 % (62 mmol/mol) respectively. Initial and 5-year mean HbA1C levels of controls were 7.9 +/- 1.08 % and 8.6 +/- 1.8 %. Mean HbA1c values were significantly lower in those receiving CSII therapy throughout follow-up. Basal and total insulin doses were significantly lower in the CSII group at all times. HbA1c was compared between subjects by age (0-5, 6-11 and 12-18 years) with no significant difference between them. Conclusion: Although CSII mean HbA1c values exceeded accepted good metabolic control limits after 5 years, CSII produces better HbA1c control at all times and in all age groups compared to MDI.

The aim of this study was to determine the prevalence of impaired hypoglycemia awareness (IHA) in children and adolescents with type 1 diabetes mellitus using a professional continuous glucose monitoring (CGM) system and to show the effect of structured education on glycemic variability (GV) in children and adolescents with IHA. Forty type 1 diabetic children and adolescents with a diabetes duration of at least five years were eligible for inclusion in this prospective, quantitative study. All subjects were asked about their history of being aware of the symptoms of hypoglycemia using a questionnaire. Professional CGM was conducted in all of the patients for six days. The frequency of IHA detected by comparison of CGM and logbook reports were analyzed. Patients with identified IHA underwent a structured training program. After three months, CGM was re-applied to patients with IHA. The study was completed by 37 diabetic children and adolescents. After the initial CGM, nine patients (24.3%) were found to have had episodes of IHA. Area under the curve (AUC) for hypoglycemia and number of low excursions were; 1.81±0.95 and 8.33±3.60 for the IHA group at the beginning of the study. AUC for hypoglycemia was 0.43±0.47 after three months of structured education the IHA patients (p=0.01). Coefficient of variation which shows primary GV decreased significantly although unstable at the end of education in IHA patients (p=0.03). CGM is a valuable tool to diagnose IHA. IHA, GV and time in range can be improved by education-based intervention.

The current COVID-19 pandemic has forced health care teams to look for alternative approaches to manage a great number of children with diabetes not only in rural but also in urban locations. Our aim in this COVID-19 pandemic was to provide information about the follow-up of new onset type 1 diabetes (T1D) patients and to discuss the integration of telemedicine into routine clinical care in the long term. The changes in Coefficient of variation (CV), standard deviation (SD); percentage of time in range (TIR), time below range (TBR) and time above range (TAR) were evaluated in 8 patients with new-onset T1D diagnosed in Pediatric Diabetes division of Ege University, during COVID-19 pandemic over a period of two-months follow-up using telemedicine system. Median follow-up time was 51 (24-66) days. Two of the patients were using low glucose suspend system and 6 were on multiple dose daily injection therapy (MDI). Target TIR values were achieved in 7 patients in the last televisit and according to last consensus suggestions' TBR <70 mg/dl (3.9 mmol/l) (level 1 hypoglycemia) of <4% and a TBR <54 mg/dl (3.0 mmol/l) (level 2 hypoglycemia) of <1% were achieved in all patients. Seven patients achieved a CV of < 36 % in their last televisit. Telemedicine as an alternative follow-up tool during unusual circumstances such pandemics, even in countries where it is not routinely used, could be beneficial to achieve optimum glycemic control in patients with new-onset T1D.

Objective: Diabetic ketoacidosis (DKA) is a life-threatening, acute complication of type 1 diabetes mellitus (T1DM). Infection is the most common precipitating factor for DKA, being responsible for more than 50% of such complications. The frequency and severity of DKA in children with T1DM, before and during the coronavirus disease 2019 outbreak were evaluated and compared with pre-pandemic presentation and severity rates.Methods: In total, 199 patients younger than 18 years were included in the study. Patients were divided into two groups: the Coronavirus disease-2019 (COVID-19) pandemic group (new onset T1DM presenting from March 2020 to March 2021; the control group included new onset T1DM from March 2016 to March 2020.Results: The rate of DKA at presentation was similar (p=0.393) during the pandemic period (58.3%) compared to the pre-pandemic years (44.8-64.3%). Although the percentage of DKA was similar, the rate of severe DKA in the COVID-19 group was higher than previous years. Although not significant, the duration of diabetes symptoms was longer in the COVID-19 period than the previous years.Conclusion: This study suggests that the rate of severe DKA, but not the overall rate of DKA, has increased during the COVID-19 pandemic compared to the prior four years. This may be due to the behavior of the parents of sick children and the limited access to the healthcare system. Despite this limited access, parental concern may have been sufficiently high to seek medical attention for their children, avoiding an increased frequency of DKA as the first presentation of new-onset T1DM.

Objective: Pump-treated children with type 1 diabetes (T1DM) have widely differing basal insulin (BI) infusion profiles for specific periods of the day. The pattern of BI requirements depends on the timing and magnitude of cortisol and growth hormone secretion within each age group. In adolescents and young adults, a decreased insulin sensitivity is seen, particularly in the early morning (dawn phenomenon) and to a lesser extent, in the late afternoon (dusk phenomenon). Different approaches exist for the inititation of basal rates. However, there is a lack of evidence-based recommendation, especially in young children. Usually the basal rates are set equally throughout day and night or the day is divided into tertiles. The aim of this study was to analyze the change of the initial, equally distributed, BI rates over the first year of standard insulin pump therapy. Methods: A total of 154 patients with T1DM, aged between 0 and <21 years at diagnosis, from a single center were documented. Patients were divided into five age groups according to age at pump initiation: group 1, 18 years, (n=5). Distribution of hourly basal rates at the initiation of the pump and at the end of first year were evaluated. Results: Median (range) age and diabetes duration was 14.46 (1.91-26.15) and 7.89 (1.16-17.15) years, respectively. Forty-four percent were male, 56% were female. Mean total insulin dose/kg in the whole cohort at the initiation and after one year of pump therapy was 0.86 +/- 0.23 U/kg and 0.78 +/- 0.19 U/kg, respectively and differed significantly between each age group (p<0.001; p<0.001). Mean daily basal rate/kg showed significant differences between the five groups (p<0.001). Circadian distribution of BI differed markedly among the five age groups. Conclusion: At the initiation of insulin pump therapy, circadian profiles by age group should be taken into account in pediatric patients to optimize basal rate faster and more easily.
