It has been suggested that cytokine release during DKA may result in capillary perturbation and thus may contribute to the development of its acute clinical complications (i.e.cerebral or pulmonary edema). We studied in 38 newly diagnosed T1DM children with DKA, aged 7.68±3.07 years, plasma levels of cytokines IL-1β (interleukin-1β), IL-2, IL-6, IL-8, IL-10, TNF-α (tumour necrosis factor-α) and also WBC (white blood cell count), hs-CRP (high sensitivity C-reactive protein), GH (growth hormone) and cortisol, prior to, during and 120h after DKA management, with the aim to monitor their levels at different time-points and in different degrees of DKA severity. Prior to DKA management the levels of IL-6, IL-8, IL-10, WBC and cortisol were elevated, but were all reduced within 120h after DKA management. Then the patients were divided into two groups: a. moderate/severe: pH≤7.2, b. mild DKA: pH>7.2. In the group with moderate/severe DKA (ph≤7.2), IL-10 levels were the highest of all cytokines, but were significantly decreased after 6h (91.76 vs 18.04 pg/mL, p=0.008), with no further change, while IL-6 levels were decreased at 120h (28.32 vs 11.9 pg/mL, p=0.003). The above were not observed in the group with mild DKA. In conclusion, in the children with DKA of our study, in the group with moderate/severe DKA the IL-10 levels were prematurely reduced at 6 hours, while the IL-6 levels remained high and were reduced at 120 hours after the DKA management. These changes may be responsible for increased capillary perturbation, which could lead to the subsequent development of acute DKA complications.

Background/Aims: Type 1 diabetes (T1DM) is associated with autoimmune thyroid, celiac, autoimmune gastric and Addison’s disease. Our aim was to investigate the prevalence of associated autoantibodies in relation to the demographic and β-cell autoantibody status (anti-GAD). Methods: Antibodies against thyroid peroxidase (anti-TPO), thyroglobulin (anti-Tg), tissue transglutaminase (anti-tTG IgA), parietal cells (APCA) and adrenal tissue (AAA) were measured in 144 children with T1DM with a mean ± SD age of 12.3 ± 4.6 years and a diabetes duration of 4.6 ± 3.8 years. Results: The prevalence of antibody positivity among our patients was: anti-GAD 53.2%, anti-thyroid (anti-TPO 17.4%, anti-Tg 11.1%); anti-tTG IgA 7.6%, APCA 4.0%, and AAA 0%. Among the children with positive anti-thyroid antibodies, 60% developed autoimmune thyroiditis, while among those anti-tTG IgA positive, 62.5% developed biopsy-confirmed celiac disease. Female gender was more frequent among anti-tTG IgA-positive patients (OR 4.47, p = 0.068), while increasing age was associated with anti-Tg positivity (OR 22.9, p = 0.041). The presence of anti-thyroid antibodies was associated with the presence of anti-GAD (OR 1.45, p = 0.01) and parietal cell antibodies (OR 4.98, p = 0.09). Conclusion: Among T1DM patients, the prevalence rates of anti-thyroid and parietal cell antibodies increased with age and diabetes duration. As the presence of anti-GAD was associated with gastric and thyroid autoimmunity, it could serve as marker for the development of additional autoimmunity in adolescents with diabetes.

Over the past few decades, the scientific community has been highly concerned about the obesity epidemic. Artificial sweeteners are compounds that mimic the sweet taste of sugar but have no calories or carbohydrates; hence, they are very popular among patients suffering from diabetes or obesity, aiming to achieve glycemic and/or weight control. There are four different types of sweeteners: artificial, natural, rare sugars, and polyols. Artificial and natural sweeteners are characterized as non-nutritional sweeteners (NNSs) since they do not contain calories. The extended use of sweeteners has been reported to have a favorable impact on body weight and glycemic control in patients with type 2 diabetes (T2DM) and on tooth decay prevention. However, there is concern regarding their side effects. Several studies have associated artificial sweeteners’ consumption with the development of insulin resistance, nonalcoholic fatty liver disease (NAFLD), gastrointestinal symptoms, and certain types of cancer. The present review focuses on the description of different types of sweeteners and the benefits and possible deleterious effects of the chronic consumption of NNSs on children’s health. Additionally, possible underlying mechanisms of the unfavorable effects of NNSs on human health are described.
