Quality of life (QoL) is an important parameter that affects the choice of therapy. Assessment of QoL and satisfaction with therapy using the rtCGM in children with T1D aged < 7 years was conducted. The study group consisted of 38 children with T1D aged < 7 years (34% aged 2–4, 66% aged 5–7 years), HbA1c: 6.53 ± 0.63%, duration of diabetes: 2.6 ± 1.6 years, treated with an rtCGM-augmented insulin pump for 1.92 ± 1.15 years. Two anonymous surveys were conducted: a. PedsQL3.0 diabetes standardized questionnaire—QoL assessment among age groups: 2–4/5–7 years. b. An original survey assessing the CGM use satisfaction. The mean scores in PedsQL3.0: communication 75%, worries 30%, treatment 70%, and problems associated with diabetes 65%. The QoL scale is: 0–19% very low, 20–39% low, 40–59% moderate, 60–79% high, 80–100% very high. The most frequently reported concerns were long-term diabetes complications and prick pain. Satisfaction with CGM use was high (68% in group aged 5–7 and 92% 2–4 years). Twenty-seven (71%) caregivers confirmed the positive effect of CGM on sleep. During the use of rtCGM a high quality of life was reported, and the quality of sleep in their caregivers was increased.

Introduction: Autoimmune thyroid diseases (AIT) are one of the most common disorders associated with type 1 diabetes (T1D) and they are capable of influencing its course. For Hashimoto's lymphocytic thyroiditis, the incidence is 14-28%, while for Graves-Basedow hyperthyroidism it is 0.5-7%. Aim of the study: Assessment of type 1 diabetes in the pediatric population with coexisting autoimmune thyroid diseases: Hashimoto's lymphocytic thyroiditis and Graves-Basedow's disease. Material and methods: Analyzing publications from the PubMed scientific database from 1990 to May 2020. Results: Among pediatric patients with T1D and coexisting thyroid autoimmunity insufficient glycemic control is usually observed. Reported average increase in glycated hemoglobin concentration ranges from 7.9 to 9.2%. In children with T1D and subclinical hypothyroidism, an increased number of episodes of hypoglycemia was noted -5 vs. 2 episodes per year among children with euthyroidism. In hyperthyroidism patients the number of episodes of hypoglycemia was 34.4 vs. 17.2 per 100 incidents in euthyroidism patients. An increased occurrence of diabetic ketoacidosis events may also be observed -18.1 vs. 7.7 per 100 patients with euthyroidism per year. The risk of developing chronic complications in the form of cardiovascular diseases is also higher. However, basing on the available literature, this subject is still debatable. Conclusions: Autoimmune thyroid diseases often accompany and interfere with type 1 diabetes in children and adolescents. Paying special attention to the different course of diabetes in the presence of thyroid disorders is an important and essential element of diabetes care.
