Diabetes mellitus is a risk factor of cardiovascular diseases. ECG of patients with diabetes mellitus type 1 (DM 1) shows tachycardia (block of parasympathetic innervation) and abnormal repolarization (increased QT interval and QT dispersion (QTd)) indicating a risk of ventricular tachycardia and sudden death in young people with DM 1. The aim of the present report was to measure 145 parameters of the heart electric field in 22 patients (14 men, 8 women) with DM 1 without complications (mean age 32.8+/-11.4 years) and in 22 controls (11 men, 11 women, mean age 30.1+/-3.4 years). The duration of diabetes was 13.9+/-7.8 years. The parameters were registered by the diagnostic system Cardiag 112.2 and statistically evaluated by the Student and Mann-Whitney test. Tachycardia (86.3+/-2.7 beats.min(-1)), shortening of both QRS (79.9+/-1.6 ms) and QT (349.0+/-5.9 ms) and increased QT dispersion (115+/-36 ms) were observed in DM 1 when compared with the controls (75.0+/-2.1 beats. min.(-1), QRS 89.9+/-2.7 ms, QT 374.0+/-4.4 ms, QTd 34.0+/-12.0 ms, p<0.01). The QTc was 415.2+/-4.1 ms in DM 1 and 401.4+/-6.6 ms in controls (NS). Other significant findings in DM 1 were: higher maximum of depolarization isopotential maps (DIPMmax) in the initial phase of QRS and less positive in the terminal phase, more negative minimum (DIPMmin) during QRS similarly as the minimum in depolarization isointegral maps (DIIMmin) and the minimum in isointegral map of the Q wave (Q-IIMmin), lower maximum in repolarization isopotential maps (RIPMmax) and less negative minimum (RIPMmin), more negative amplitude of Q wave (Q-IPMAM) and more pronounced spread of depolarization (activation time). Our results confirmed a decreased parasympathetic to sympathetic tone ratio (tachycardia, shortening of the activation time) and revealed different depolarization and repolarization patterns in DM 1. The differences in heart electric field parameters measured by the BSPM method in DM 1 and in the controls indicate the importance of ECG examination of diabetic patients type 1 in the prevention of cardiovascular diseases.

The aim. To identify the features of corneal sensitivity of the sick and the fellow eye in bacterial keratitis patients with or without diabetes mellitus. Materials and methods. The analysis was performed on the basis of survey data of 62 type 1 diabetes patients with bacterial keratitis and 43 nondiabetic control patients with bacterial keratitis. The examination was performed at the first visit. In addition to standard ophthalmic examination, the patients underwent fluorescein test, OCT of the anterior segment of the eye, non-contact corneal aesthesiometry. Results and discussion. The average corneal sensitivity threshold in diabetic patients with bacterial keratitis at the first visit at all air flow temperatures exceeded the corresponding indicators in nondiabetic patients of the control group: by 33.5% at an air temperature of 5 °C, by 30.6% at 15 °C, by 28.8% at 20 °C, by 27% at 30 °C, and by 26.1% at 40 °C (p<0.05). The average corneal sensitivity threshold at a temperature of 20 °C in the fellow eye in diabetic patients with bacterial keratitis exceeded that in nondiabetic patients with bacterial keratitis of the control group by 32.9 % (p<0.05). Conclusions. Corneal sensitivity of the sick and fellow eye in patients with bacterial keratitis depends on the presence of diabetes mellitus. The average threshold of corneal sensitivity of the sick and fellow eye in diabetic patients with bacterial keratitis at the first visit exceeds the corresponding values in nondiabetic patients with bacterial keratitis.

Aim. To estimate dynamics of secretory and motor-evacuational functions of the stomach in patients with type 1 diabetes mellitus and gastrointestinalform of diabetic neuropathy. Materials and methods. 32 patients with DM1 without gastrointestinal pathology allocated to different groups depending on DM duration (gr. 1 lessthan 10 yr, gr. 2 over 10 yr). Vegetative equilibrium was estimated from the Kerdo index, rehabilitative potential from its basic constituent (morphophysiologicalindex). The motor-evacuational function of the stomach was studied with the use of a scintillation gamma-chamber, the gastric secretoryfunction by pH measurements. Results. Half of the patients in gr 2 presented with hypersympathicotony. The frequency of hypertonic form of gastric tone increased with durationof DM while the acid-producing and evacuational functions of the stomach decreased (as estimated by pH-measurement and gastroscintiographyrespectively). The propulsive function most significantly decreased in the pyloric part. The efficacy of rehabilitation of diabetic patients with gastrointestinalform of diabetic neuropathy was much lower than in those with preserved vegetative function of the stomach. Conclusion. Impairment of evacuational function of the stomach and duodenum with DM1 duration may be a cause of unstable blood glucose level.Hypomotor dyskinesia of the upper gastrointestinal tract due to DM1 and deficit of parasympathetic innervation occurs more frequently in patientswith low rehabilitative potential. Functional changes in the gastrointestinal tract of DM1 patients do not depend on the quality of compensation ofmetabolic disorders but correlate (r=-0.39) with DM duration. It is concluded that the gastrointestinal form of diabetic neuropathy impairs rehabilitativepotential of fhe patients.

Since the autoimmune nature of type 1 diabetes mellitus came to become known some 40 years ago, continuous investigations have been carried out in an attempt to improve approaches to prognostication of this disease and develop new safe and efficacious methods for its prevention. For all that, many aspects of diabetes pathogenesis still remain far from clear. In most cases (roughly 85%), type 1 diabetes mellitus (DM1) develops sporadically in the absence of a relevant familial or hereditary history of this condition. Accordingly, the first-degree relatives account for only 15% of all DM1 patients. The risk of development of DM1 in the Russian population estimated by the researchers of the Children' Department, Endocrinological Research Centre, is relatively low (0.2%). It depends on many factors, such as the number of ill and healthy relatives, the chronological age of a given patient and the age of onset of clinical manifestations in his (her) relatives. Type 1 diabetes-predisposing and protective haplotypes were identified in the Russian population based on the results of molecular-genetic studies involving 599 children and adolescents with DM1. These and immunological data were used to distinguish between risk groups in the families of diabetic patients and the rationale was proposed for the dynamic follow-up of these subjects. It is concluded that estimation of the risk of type 1 diabetes mellitus based on the results of molecular-genetic studies and monitoring immunological markers constitutes the first step in the elaboration of preventive measures designed to prevent or delay the development of the disease.

Type 1 diabetes mellitus is considered an autoimmune disease mediated by Th1 lymphocytes, while allergic diseases are characterized by Th2-mediated immune response. Their incidence is rising in developed countries and the interaction between autoimmune and atopic diseases has been a subject of interest for decades. There are many controversies about the association or mutual exclusion of these diseases, but classical paradigm based on the assumption that diseases mediated by Th1 and Th2 should be mutually exclusive, has been revised considering both the role of regulatory T cells Threg, and the environmental factors involved. The aim of this review is to investigate the association of allergic diseases (rhinitis, asthma, dermatitis) in patient diagnosed with type 1 diabetes mellitus. The studies that attempted to shed light on this topic had surprisingly varied results. These ranged from statistically significant proof of an inverse association between an autoimmune disease and one or several atopic ones to other implying positive associations. Although up to now studies on this subject present seemingly discordant results, each attempt raises new questions and sheds light on new factors involved in the interaction of these diseases. They present much needed stepping stones for future studies to learn from and adapt.

Abstract Background: Adult patients diagnosed with type 1 diabetes mellitus are at risk for ventricular arrhythmias and sudden cardiac death. Aim: The objective of our study is to evaluate the electrocardiographic data of children diagnosed with type 1 diabetes mellitus and to determine the possibility of arrhythmia in order to prevent sudden death. Methods: Electrocardiographic data of 60 patients diagnosed with type 1 diabetes mellitus and 86 controls, who were compatible with the patient group in terms of age and gender, were compared. Results: The duration of diabetes in our patients with type 1 diabetes mellitus was 5.23 ± 1.76 years, and the haemoglobin A1c levels were 9.63% ± 1.75%. The heart rate, QRS, QT maximum, QT dispersion, QTc minimum, QTc maximum, QTc dispersion, Tp-e maximum, Tp-e maximum/QTc maximum and the JTc were significantly higher compared to the control group. There was no significant correlation between the duration of type 1 diabetes mellitus and HbA1c levels and the electrocardiographic data. Conclusion: We attributed the lack of a significant correlation between the duration of type 1 diabetes mellitus and the haemoglobin A1c levels and the electrocardiographic data to the fact that the duration of diabetes was short, since our patients were children. We believe that patients with type 1 diabetes mellitus should be followed up closely in terms of sudden death, as they have electrocardiographic changes that may cause arrhythmias compared to the control group. However, more studies with longer follow-up periods are necessary to support our data.

Abstract Urinary N-acetyl-beta-glucosaminidase (NAG) and its isoenzymes (NAG A and NAG B) in samples from 87 type 1 diabetic patients and 40 apparently healthy reference subjects were studied with enzyme immunoassays. The diabetic patients had higher concentrations of urinary NAG than did the control subjects (P less than 0.01), but the isoenzyme pattern did not differ. There was a positive correlation between metabolic control (Hb A1c concentrations) and total NAG (P less than 0.01), NAG A (P less than 0.01), and NAG B (P less than 0.001). The diabetic patients were divided into three groups, depending on the degree of retinopathy. Subjects with severe forms of retinopathy did not have increased concentrations of urinary NAG unless they had concomitant nephropathy. The isoenzyme pattern was similar irrespective of degree of retinopathy or nephropathy. The results indicate that concentrations of urinary NAG are positively correlated to the degree of nephropathy, whereas there is no such correlation to the degree of retinopathy.

AbstractReceptor for advanced glycation endproducts (RAGE) plays the essential role in the pathogenesis of diabetic vascular complications. The aim of the study was to compare concentration of soluble RAGE and its ligands (EN-RAGE and HMGB1) with different biochemical parameters in Type 1 (T1DM) and Type 2 (T2DM) diabetes mellitus.Total number of 154 persons (45 T1DM, 68 T2DM, 41 controls) was examined and concentrations of sRAGE, EN-RAGE and HMGB1 were measured and compared to diabetes control, albuminuria, cell adhesion molecules and metalloproteinases (MMPs).Mean serum sRAGE concentration was higher in T1DM as compared to controls (1137±532 ng/l vs. 824±309 ng/l, p<0.01). Similarly, EN-RAGE was significantly higher in both diabetic groups (p<0.001) and HMGB1 concentrations were elevated in T2DM patients (p<0.01). Significant relationship was found between MMP9 and HMGB1 and EN-RAGE in diabetic patients. Inverse relationship was observed between MMP2 and MMP9 in both types of diabetic patients (r= − 0.602, p<0.002 and r= − 0.771, p<0.001). Significant positive correlation was found between sRAGE and ICAM-1, VCAM-1 or vWF (p<0.01 to p<0.001).We conclude that serum sRAGE and RAGE ligands concentrations reflect endothelial dysfunction developing in diabetes.

Type 1 diabetes mellitus (T1DM) is a complex condition caused by the destruction of pancreatic beta cells by autoimmune mechanisms. As a result, insulin deficiency and subsequent hyperglycemia occur. The aim of the present study is to investigate the role of adiponectin and tumor necrosis factor alpha (TNF-α) in the development of T1DM. The study is designed as an observational case-control study, involving 52 diabetic patients and 66 controls. Z scores for Body Mass Index (BMI), weight, height, and adiponectin and TNF-α serum levels were assessed in both groups. The T1DM group had significantly higher TNF-α levels and a significantly higher proportion of high-risk patients for inflammation based on TNF-α values as compared to the control group, while both groups had statistically similar adiponectin levels and a similar proportion of high/medium-risk patients based on adiponectin values. TNF-α plays a significant role in the pathogenesis and evolution of T1DM and it may represent an additional marker of disease progression, as well as a potential target of immunotherapeutic strategies. In the present study, no statistically significant differences were recorded in adiponectin levels neither in diabetic patients and controls, nor in high/medium severity risk diabetic patients.

Category: Diabetes Introduction/Purpose: Diabetes mellitus (DM) poses a risk for increased rate of complications in many orthopaedic procedures, especially in patients undergoing elective arthroplasty procedures. Treatment of end-stage ankle arthritis includes both arthroplasty and arthrodesis. Current literature provides minimal guidance regarding outcomes of total ankle replacement (TAR) or ankle arthrodesis (AA) in diabetic patients. The authors of this study utilized a large database to compare rates of postoperative complications and reoperations of diabetic patients undergoing surgical management of ankle arthritis to rates seen in non-diabetic patients. Methods: Using the PearlDiver Technologies, Inc. database, Medicare patients diagnosed with ankle arthritis using ICD-9 codes were identified from 2005 to 2014. Patients were then sorted as diabetic or non-diabetic. Diabetic patients were then further stratified into Type 1 diabetes (T1DM) and Type 2 diabetes (T2DM). Type 2 diabetics requiring insulin (T2ID) and not requiring insulin (T2NID) were also isolated. Patients were identified who underwent either AA or TAR utilizing ICD-9 procedure and CPT codes. These groups were evaluated for postoperative complications and reoperation rates. Chi-Squared testing was used to determine significance. Multivariate analysis was performed to determine whether diabetes represents an independent risk factor. Results: 1477 diabetic patients underwent TAR and 5399 underwent AA versus 3900 TAR and 7838 AA in nondiabetics. Diabetics undergoing AA experienced complications at 32.2%, reoperations at 30.8%, and revisions at 18.7% versus 13.3%, 22.3%, and 19.2% respectively in patients without diabetes(P<0.05). In diabetics undergoing TAR, the complication rate was 21.6% and reoperation rates were 16.9% versus 12.5% and 13% respectively in their non-diabetic counterparts(P<0.05). Revision rates were similar. Patients with T1DM had more reoperations and complications in both TAR and AA compared to those with T2DM (P<0.05). In both surgical groups, Patients with T2ID had more complications and reoperations than those with T2NID(P<0.05). Multivariate analysis revealed diabetes as an independent risk factor for complication and reoperation in AA but only complication in TAR(P <0.05). Conclusion: Patients with a diagnosis of diabetes mellitus experienced higher complication and total reoperation rates when undergoing either TAR or AA. T1DM appears to impart a greater risk of surgical complication and repeat surgical intervention than does T2DM. However when insulin is required in T2DM, complication and reoperation rates are similar to those of T1DM. Patient selection for surgical management of end-stage ankle arthritis should incorporate diabetic type and insulin dependency when considering surgical intervention.

In this review, we will try to analyze the possible coexistence between epilepsy or seizures and type 1 diabetes mellitus (T1DM), in order to establish if there is more than a casual association, and to investigate possible mechanisms underlying this link. Anti-glutamic acid decarboxylase antibodies (GAD-Abs) have been associated with T1DM and a great number of neurological diseases such as epilepsy. Epilepsy can be a feature of a large variety of autoimmune or inflammatory disorders. GAD-Abs can have a role at the basis of the possible link between epilepsy and T1DM, although their real pathogenetic mechanism in neurological diseases is still unknown. Metabolic conditions such as hypoglycemia and hyperglycemia, common problems in diabetic patients, may be also implicated, even if their underlying mechanism is minimally understood.
