Epidemiological Characteristics

Aim. To study dynamics of main epidemiological characteristics (incidence and prevalence) of type 1 diabetes mellitus (DM) in children in theRussian Federation (RF) and its Federal districts (FD) in 2001-2007. Materials and methods. Analysis of main epidemiological characteristics (incidence, prevalence, mortality) of type 1 DM in children of RF has beenunderway in the Institute of Pediatric Endocrinology, ERC, since 2001 based on results of questionnaire studies. The questionnaires regularly distributedamong Health Committees of RF subjects (primary sources of information) are designed to collect data on the size, age and sex compositionof childrens populations affected by DM1 and the number of newly diagnosed cases as per the end of each reporting year. The data obtainedare compared with those stored in the State Diabetes Registry (secondary source of information). Results. Major trends in the dynamics of epidemiological characteristics of type 1 DM in children of RF are similar to those worldwide. Mean annualgrowth rate is 2,8%. The incidence of DM1 remains highest in the North-West FD (15,66 per 100 000 children) followed by Central andVolga FDs (12,82 and 10,6 respectively) where its is close to the average value FDr RF (11,01). The incidence of DM1 continues to decrease in theSouthern FD (6,61% per year) and undergoes up-and-down fluctuations in Ural and Siberian FDs. It steadily grows in the Far East FD. TheNorth-South gradient of DM1 morbidity across the territory of RF has persisted during the study period. Conclusion. Monitoring main epidemiological characteristics of type 1 diabetes mellitus in children of RF is an integral component of the organizationof medical and preventive aid to these patients that creates a basis for predicting morbidity, planning measures for its control, and improvinggeneral quality of healthcare provided to diabetic children

Epidemiological Characteristics

Aim. To assess main epidemiological characteristics (prevalence, morbidity, mortality) of type 1 diabetes mellitus (DM1) in children of the RussianFederation and its federal okrugs (districts) in 2001-2008. Materials and methods. The research was based on questionnaries designed in the Pediatric Endocrinology Institute of Endocrinology Research Center. Results. There were18,028 children aged 0-14 years with DM1 as per 01.01.2009. As many as 2,789 new caseswere diagnosed in 2008. The meanprevalence as per 01.01.2009 was estimated at 72.28 (24.88-90.63), morbidity 11.25 (3.39-14.06), mortality 0.07 (0-0.26) per 100,000 childrenspopulation.The absolute increment in morbidity from 2001 to 2008 was 1.69, growth rate 117.7%, accession rate 17.7%, mean annual rate for the8-year study period 2.2%. Morbidity is predicted to reach 13.2 per 100,000 in the next 5 years (2013). The highest morbidity recorded in the Uralokrug (14.73/100,000) exceeded that in the North-West okrug (13.63/100,000 as per 01.01.2009) where it was maximum in the preceding years.Morbidity in the Privollzhsky, Far East and Siberian okrugs remained unaltered (11.06, 7.3, 10.6 respectively), decreased in the Southern okrug(8.0) and increased in the Central okrug from 13.3 in 2007 to 14.3/100,000 in 2008. The overall prevalence of DM1 among children in Russia increasedfrom 54.6 to 72.28 per 100,000. Conclusion. The main tendentious in DM1 epidemiology in children in RF are comparable with those worldwide.

AbstractThe aim of the study was to determine the frequency and titers of anti-thyroid peroxidase (Anti-TPO), anti-thyroglobulin (Anti-TG), and anti-glutamic acid decarboxylase (Anti-GAD) antibodies in Turkish patients with type 1 diabetes mellitus (DM), and to compare the frequency of anti-TPO and anti-TG titers in the presence or absence of anti-GAD. A total of 104 patients including 56 males and 48 females with type 1 DM and their age-, gender-, and body mass index-matched control group, including 31 males and 27 females, 58 cases in total with an age range of 15-50 years, were recruited into this study. In patients with type 1 DM, positive anti-GAD was detected in 30.8% (n=32). In patients with positive anti-GAD, rate of positive anti-TPO was 37.5%; however, in patients with negative anti-GAD, the rate of positive anti-TPO was 9.7% and the difference was statistically significant (p=0.001). In patients with positive anti-GAD, the rate of positive anti-TG was 18.8%. In patients with negative anti-GAD, the rate of positive anti-TG was 2.8%, and the difference between them was statistically significant (p=0.005). In patients with positive and negative anti-GAD, rates of both positive anti-TPO and anti-TG were 15.6% and 1.4%, respectively, with the difference showing statistical significance (p=0.004). Thyroid autoimmunity in type 1 DM patients with positive anti-GAD was apparently higher; therefore, these patients should be followed more frequently and carefully.

Background: Type 1 diabetes mellitus (DM) patients surviving myocardial infarction (MI) are at heightened risk for the subsequent development of heart failure (HF). Despite the worse outcomes, investigations into the pathophysiological mechanisms that contribute to the increased frequency of HF after MI in the type 1 DM heart remain scarce. Neuregulin-1 (NRG-1), along with the ErbB family of receptor tyrosine kinases through which NRG-1 ligands signal, have been shown to be intimately involved in mediating cardiac recovery after MI. However, the impact of type 1 DM on this signaling system post-MI remains to be elucidated. Therefore, in the present study, we examined myocardial NRG-1/ErbB signaling during post-MI HF in the presence of type 1 DM. Methods: Type 1 DM was induced in male Sprague-Dawley rats via a single intraperitoneal injection of streptozotocin (STZ) (65 mg/kg). Two weeks after induction of type 1 DM, MI was produced in DM and non-DM rats by ligation of the left anterior descending (LAD) coronary artery. Residual left ventricular (LV) function was assessed by echocardiography at 4 weeks post-MI. Following echocardiographic assessment, NRG-1, ErbB2, and ErbB4 protein expression was assessed in the remote, surviving LV myocardium of DM and non-DM rats using Western blot techniques. Results: LV Fractional Shortening (FS) and LV Ejection Fraction (EF) were significantly lower in the DM + MI group compared to the MI group ([LVFS: DM + MI, 17.9 ± 0.7 (n=6) vs. MI, 25.2 ± 2.2 (n=6), p <0.05; LVEF: DM + MI, 35.5 ± 1.4 (n=6) vs. MI, 47.5 ± 3.5 (n=6), p <0.05]), indicating an increased functional severity of HF in the diabetic post-MI group. The weight of myocardial scar caused by the infarction was not significantly different between the MI groups ([DM + MI, 0.19 ± 0.02 g (n=4) vs. MI, 0.20 ± 0.03 g (n=4), p =0.70]). ErbB2, ErbB4, and NRG-1 protein expression levels were all significantly lower in the DM + MI group compared to the MI group. Conclusions: These findings demonstrate that type 1 DM impairs myocardial NRG-1/ErbB signaling in response to MI, which may contribute to the accelerated progression of subsequent HF. Augmentation of NRG-1 or its downstream signaling pathways may represent a novel therapeutic strategy for ameliorating post-MI HF in the setting of type 1 DM.

Type 1 Dm

Type 1 diabetes mellitus (T1DM) has been linked to many autoimmune problems. The association between T1DM and urticaria warrants investigation. Data were extracted from the National Health Insurance Research Database (NHIRD) of Taiwan. Participants with T1DM were recruited as the case group, and that group was matched by sex and age at a ratio of 1:4 to the control group comprising those without T1DM. The study period was 1998–2011. All participants were followed up to the diagnosis of urticaria, withdrawal from the insurance program, death, or the end of the study. A multivariable Cox proportional hazard model was used to calculate the adjusted and crude hazard ratios for urticaria. A total of 5895 participants (1179 in the case group and 4716 in the control group) were followed up in the study. The total incidence rate of urticaria in patients with type 1 DM was 26.6 per 1000 person-years, and that in controls was 6.85 per 1000 person-years. Compared with the control group, the hazard ratio of urticaria in the case group was 2.84 (95% CI = 2.27–3.56). Compared with age-matched participants without T1DM, patients with type 1 DM aged <18 years had a 3.62-fold higher risk of urticaria (95% CI = 2.85–4.59). The hazard ratio in patients with an adjusted Diabetes Complications Severity Index (aDCSI) score of 1.01–2.00 per year was 2.57 (95% CI = 1.18–5.57), and that in patients with an aDCSI score of >2.00 per year was 4.47 (95% CI = 2.68–7.47). T1DM patients aged <18 years had an increased risk of urticaria, but a similar phenomenon was not observed among T1DM patients older than 18 years.

Pathogenesis of Type 1 Diabetes Mellitus: A Brief OverviewBefore the discovery of insulin, type 1 diabetes mellitus (DM) was a disease with acute evolution, leading to death shortly after diagnosis. During the first years of insulin therapy, the medical world was optimistic, even enthusiastic, considering that the therapeutic solution for the malady was found. Unfortunately this was only an illusion, because the patients started to develop chronic complications that shortened their lifespan and impaired their quality of life. In other words, insulin therapy transformed type 1 DM into a chronic disease. The prevention or the delay of the onset of hyperglycemia emerged as a new solution for the patients and, consequently, the understanding of the pathogenesis of the disease (a prerequisite for developing efficient preventive methods) became a priority for all the diabetologists involved in research. Almost 40 years have passed since the autoimmune theory regarding the pathogenesis of type 1 DM was imagined but, despite the tremendous research performed in this field since then, the prevention could not be obtained. The aim of this paper is to present the most important theoretic notions regarding the mechanisms that underlie the development of type 1 DM, in the way they are understood today.

Aim. To investigate the technical difficulties of performing the stages of vitreoretinal surgery, the peculiarities of the surgical technique in young patients with the proliferative stage of diabetic retinopathy (DR). Methods. Twelve patients (12 eyes) with type 1 diabetes mellitus (DM) were selected. Their average age was 26±2 years (from 19 to 30 years). There were 4 men and 8 women. All patients had DM since childhood. Selection criteria: presence of indications for vitreoretinal surgery for proliferative DR, age of patients with type 1 DM not more than 30 years, onset of DM in childhood. Results. Initially, the clinical manifestations of proliferative DR in young people with type 1 DM were distinguished by the severity of neovascular and fibrous growths, a tendency to hemorrhages, and the complexity of preoperative preparation in the form of panretinal laser coagulation, at least partial. Surgical removal of vitreoretinal adhesions and elimination of neovascularization zones differed in technical difficulties associated with their higher density and the area of retinal tissue lesion. Conclusion. Surgical treatment of proliferative DR in young patients has a number of technical difficulties associated with the density and length of fibrovascular vitreoretinal growths, the difficulty of separating them due to the high tendency of newly formed vessels to hemorrhages. Key words: proliferative diabetic retinopathy; endovitreal surgery; type 1 diabetes mellitus; young age.

Abstract Background: The objective of the study was to analyze salivary flow rate, urea concentration, and buffer capacity in adolescents with type 1 diabetes mellitus (type 1 DM) in two different stages. Methods: This study was performed on adolescents (14–19 years), allocated between two groups: type 1 DM group comprised 32 adolescents with type 1 DM, and non-type 1 DM group comprised 32 nondiabetics. The adolescents in type 1 DM group were evaluated at a baseline (T0) and after 15 months (T1), and those in non-type 1 DM group were only evaluated at T0. Diabetic status was determined by glycosylated hemoglobin (GHb) and capillary glucose tests. Measurement of salivary flow was performed by means of stimulated saliva (SSFR) collection. The buffer capacity (BC) was determined, and analysis of urea salivary concentration was performed using the colorimetric method. Results: At T0, there were significant differences between diabetics and nondiabetics for SSFR and BC (p<0.05). In diabetics, SSFR was 0.790 mL/min in T0 and 0.881 mL/min in T1 (p>0.05). BC at T0 was 4.8, and at T1, it was 3.9 (p=0.000). Urea concentration mean value had a significant decrease at T1 (28.13) compared with T0 (34.88) (p=0.013). There was a negative correlation between SSFR and urea salivary concentration at both T0 (r=−0.426, p≤0.05) and T1 (r=−0.601, p≤0.01). Conclusions: In adolescents with type 1 DM, hyposalivation at T0 was associated with an increase in urea salivary concentration. At T1, hyposalivation was associated with a reduction in BC, and an increase in salivary urea.
