Type 1 diabetes mellitus is commonly recognized as an autoimmune disease characterized by progressive destruction of pancreatic ?-beta-cells. Progress in diagnostics at preclinical stage is accompanied with active development of preventive measures. So far, there are no specific therapeutic agents approved for clinical practice. However, ongoing large-scale studies have outlined some promising solutions, antigen-specific immunotherapy being one of them.

The prevalence of dental caries is high in people with type 1 diabetes mellitus and it is about 81.1-100%, however 57.1% are diagnosed with multiple dental caries. The effectiveness of caries prevention is only 48.3%. In the prevention of dental caries has significant role to exogenous methods of prevention with fluorides, but fluoride compounds adversely affect the condition of patients with diabetes mellitus. It’s advisable to use in patients with caries preventive measures containing nanohydroxyapatite and xylitol. The purpose is to conduct a research of optimized approach to local prevention of dental caries in patients with type 1 diabetes mellitus by the fluoride-free agents, taking into account the degree of risk of dental caries in patients and the state of diabetes compensation. Materials and methods. The review of  95 patients with type 1 diabetes mellitus in the state of compensation, subcompensation and decompensation was from 18 to 35 years and disease duration was from 1 to 24 years. The main group included 50 people, the comparison group was 45 people. The index of caries intensity DMF, structure functional indices of enamel acid resistance (TER) were determined in patients. Also the increase in the intensity of dental caries after 6 and 12 months, reducing the increase in caries after 12 months were defined.The patients of the main group, according to individualized approaches, taking into account the degree of risk of dental caries and the state of compensation of diabetes mellitus were subjected to local caries preventive measures, which included the use of fluoride-free products containing nanohydroxyapatite and xylitol, and means of enzymes lactoperoxidase system, patients of the comparison group - traditional local fluoroprophylaxis. Results and discussion. In patients of the main group after 6 months of caries-preventive measures of structure functional indices of enamel acid resistance was 3.52±0.19 points, 12 months – 3.14±0.16 points, the index improved to 1.7 times (p<0,05), compared to baseline (5.26±0,27 points). In the comparison group of patients, after 6 months, enamel acid resistance was 4.09±0.21 points, after 12 months - 3.86±0.18 points, which is only 1.3 times better (p<0.05) than the baseline index (5.02±0.25 points). Before the start of caries preventive measures, the caries intensity index DMF in patients of the main group was 13.7±0.84, after 6 months it increased to 13.8±0.86, the increase in the intensity of caries was 0.1. In the patients of the comparison group, the corresponding indexes of DMF were 12.3±0.85 and 12.6±0.91, increase the intensity of caries was 0.3 and was higher by 3 times. After 12 months, patients in the main group DMF index slightly increased to 14.0±0.87, increase the intensity of caries was 0.3. In the comparison group DMF index value was 13.1±0.93, increase the intensity was significantly higher (2.7 times) and it was 0.8. Reduction of increase the intensity of dental caries was 62.5%. Conclusion. Topical application in patients with type 1 diabetes mellitus of caries prophylactic agents containing nanohydroxyapatite and xylitol, as well as agents with enzymes of the lactoperoxidase system for 12 months on individualized approaches taking into account the degree of risk of dental caries and the state compensation of diabetes mellitus promoted caries resistance of enamel 1.7 times, reducing the intensity of caries by 2.7 times, allowed to reduction the dental caries growth by 62.5%.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), though mostly sparing the lungs in children, has been found to affect other organs including the endocrine pancreas. Type 1 diabetes mellitus (T1DM) may occur through direct negative effects of the virus on beta-cell function leading to diminished insulin production. Diabetic ketoacidosis (DKA) is a known and life-threatening complication of T1DM. Case presentation: This is a case of a 3-year-old previously healthy male who presented with 4 days history of fever, with malaise and hyperpnea for one day. Review of systems was notable for increased thirst and urination, nausea, vomiting, fatigue, and visible weight loss for 4 days. Initial investigations done showed elevated blood glucose, ketonuria, increased anion gap metabolic acidosis, and positive SARS-CoV-2 polymerase chain reaction (PCR). He was immediately commenced on intravenous fluids and insulin with progressive improvement and was discharged on hospital day 6. Conclusion: Coronavirus disease-2019 (COVID-19) has impacted children most profoundly with the new post-infectious multi-inflammatory syndrome, however, it is important to remember that primary coronavirus infection is still a threat to pediatric patients, for example, and its cytotoxic effects on the pancreatic beta cells that may lead to T1DM. We, therefore, recommend that caregivers, parents, and medical professionals should have a high index of suspicion when children present with symptoms consistent with a diagnosis of T1DM during the COVID-19 pandemic so that diagnosis can be made promptly and therefore DKA prevented.

Therapeutic Targets

Ion channels are integral proteins expressed in almost all living cells and are involved in muscle contraction and nutrient transport. They play a critical role in the normal functioning of the excitable tissues of the nervous system and regulate the action potential and contraction events. Dysfunction of genes encodes ion channel proteins, which disrupt the channel function and lead to a number of diseases, among which is type 1 diabetes mellitus (T1DM). Therefore, understanding the complex mechanism of ion channel receptors is necessary to facilitate the diagnosis and management of treatment. In this review, we summarize the mechanism of important ion channels and their potential role in the regulation of insulin secretion along with the limitations of ion channels as therapeutic targets. Furthermore, we discuss the recent investigations of the mechanism regulating the ion channels in pancreatic beta cells, which suggest that ion channels are active participants in the regulation of insulin secretion.

<b><i>Introduction:</i></b> Masked hypertension (MHTN) is the finding of elevated out-of-office blood pressure (BP) measurement. This is a pilot study to evaluate the prevalence of MHTN in adolescents with type 1 diabetes mellitus (T1DM). <b><i>Patients and Methods:</i></b> Normotensive, adolescents with T1DM were recruited from Tawam Adolescents Diabetes Clinic at Tawam hospital, Al Ain, UAE. They consented to wear the ambulatory BP monitoring (ABPM) device. The heart rate and ambulatory BP were recorded at 15-min intervals for 24 h. Abnormal systolic BP (SBP) and diastolic BP (DBP) were defined as readings above 135 and 85 mm Hg; respectively. <b><i>Results:</i></b> Thirteen patients (10 females) were recruited from “Tawam Adolescents Diabetes Clinic.” The median age was 17 (15–19) years, median BMI 21.4 (14.8–29), and median diabetes duration 9 (3–12) years. All patients had normal retinal examination within the past 12 months. Family history of hypertension (HTN) was present in 6/13 (46%) patients. Office BP measurements revealed a mean DBP ± SD of 72 ± 6.9 mm Hg and mean SBP ± SD116 ± 5.5 mm Hg. The median HbA1c was 8.4% (5.6–13.7) and median GFR 125 mL/min/m<sup>2</sup> (87–134). Two patients had microalbuminuria. Twenty-four hour ABPM revealed elevated SBP and DBP in 12.2 and 5.8% of the values; respectively. Further analysis confirmed MHTN in 4 (30%) patients, nondipping pattern of BP in 5 (38%) patients, and elevated pulse pressure in 8 (61.5%) patients. Only 4 (30%) patients had normal studies. <b><i>Conclusions:</i></b> ABPM uncovered a very high prevalence of MHTN in our patients. Whenever available, ABPM provides an excellent tool for diagnosis and hence early evaluation and management of HTN in adolescents with T1DM. Well-designed large-scale studies are needed to examine the magnitude of MHTN among adolescents with T1DM.

New onset type 1 diabetes mellitus is an uncommon but possible complication triggered by SARSCoV- 2 infection. Metabolic inflammation supported by cytokine storm leading to pancreatic beta cells destruction is the most probable link between COVID-19 and diabetes. Here, we describe the case of a 51-year-old female suffering from Hashimoto thyroiditis, who came to our attenction for new onset polyuria-polydipsia syndrome associated to hyperglycemia after a mild form of COVID- 19 recognized two months before and already recovered. Type 1 diabetes was diagnosed.
