The review covers the role of transplantology in treatment of patients with type 1 diabetes and the state of its development in the world and in Russia. The results of major multicenter studies, devoted to the influence of simultaneous kidney and pancreas transplantation and kidney transplantation alone on life expectancy and quality of life of diabetic patients are summarized here. Experience in pancreas-kidney transplantation, gained in Academician V.I. Shumakov Federal Research Center of Transplantology and Artificial Organs, is described, including surgical technical and postoperative treatment. Also we perform the results of research work, devoted to the influence of pancreas transplantation on different homeostasis parameters, such as: oxidative stress parameters, homocysteine, receptor for advanced glycation endproduct (RAGE), and markers of endocrine function of pancreas transplant.

Abstract Background and Aims In patients with type 1 diabetes and end-stage renal disease, kidney transplantation improves both quality of life and survival. When simultaneous kidney-pancreas transplantation appears too invasive, or after failure of the pancreatic graft, an islet after kidney transplantation (IAK) may be considered to restore a stable endocrine function. The aim of our work was to assess the impact of islet transplantation on kidney transplantation outcomes versus insulin alone. Method In this retrospective parallel-arm cohort study in Lille, we included all type 1 diabetes patients who received a kidney graft from 2000 to 2017, followed by an islet transplantation after kidney (IAK) or not (kidney alone, KA). The primary study endpoint was the change of renal function (estimated glomerular filtration rate, eGFR). Secondary endpoints were glycemic control-related markers, such as HBA1c. Results During the period of study, 14 patients were included in the KA group versus 15 in the IAK group (including 5 after failure of a simultaneous pancreatic graft) were enrolled. At baseline, kidney donor sex, BMI, cause of death, cold ischemia time and recipient sex, waiting time on dialysis, type of dialysis, and number of previous kidney transplantation, were similar between the two groups. Yet, there were significant differences between KA and IAK, considering donor age (resp. 56.0±15.0 vs 35.2±13.7 years, p<0.001), use of perfusion machine (resp. 7 vs 0, p= 0.002), recipient age (resp. 55.7±5.7 vs 42.1±6.1, p<0.001), and recipient BMI (24.7± 1.8 vs 21.9±2.5 k/m? p=0.004). In IAK, the median (IQR) time between islet and kidney transplantation was 21.8 months (19.0 – 29.4). eGFR was not significantly different at baseline (IAK: 57.8±17.7 vs KA: 48.9±21.4 ml/min, p=0.22) but the decrease was significantly lower up to 5 years in the IAK group (IAK: 0.05±1.99 ml/min/year vs KA: -2.42±3.43 ml/min/year, p=0.03). HBA1c was similar at baseline in both groups (IAK: 7.8±1.6% versus KA: 7.9±1.1%, p=0.31), but significantly lower in the IAK group up to 5 years (IAK: 6.6±0.97% versus KA: 7.8±1.12%, p<0.001). Conclusion In patients with type 1 diabetes and a functioning kidney graft, IAK was associated with a better glucose control and a slower decrease of eGFR than standard insulin therapy. Our results suggest that IAK should be proposed to type 1 diabetes patients with a functional kidney graft.

Elevated C-reactive protein (CRP) levels have previously been described before the onset of type 1 diabetes and gestational diabetes. We hypothesized that inflammation, as reflected by elevated CRP levels, can help predict development of islet autoimmunity or type 1 diabetes. The outcome of this research is to establish potential determinants of raised CRP concentrations in type 1 diabetic patients. Sensitive assay showed ‘low-level’ CRP concentrations in 147 type 1 patients (83M, 64F, median age 30 years, range 13–67). We have done step by step variant examination to relate these CRP levels to known cardiovascular risk factors and demographic data. Only four patients had established Coronary Heart Disease (median CRP 3.43 mg/l vs. 0.85 mg/l, p=0.035). In subjects without overt CHD, multivariate analysis revealed increase in subject age (p=0.0027), BMI (p=0.001) and HbA1 (p=0.013) to be associated with a higher CRP concentration, as was female sex (p=0.025) and a history of CHD in a first-degree relative (p=0.018, n=58). Elevated CRP levels were positively associated with cardiovascular and renal risk factors: age, body mass index, blood pressure, serum cholesterol level, smoking, plasma glucose level and elevated urinary albumin excretion and presence of hypertension were unrelated. This research work advises that certain of the risk factors connected with CHD in type 1 patients are also individually predictive of high CRP concentrations. The reasons for this, and whether intervention would prove valuable, require further analysis

Pancreas transplantation is the more effective cure for type 1 diabetes. Although intensive insulin scheme has been demonstrated to reduce the incidence of diabetes related complication, only pancreas transplantation normalizes glycometabolic control, avoids the risk of severe hypoglycemic events and prevents or in some case ameliorates diabetes related complications. In this review it will be analyzed the impact of pancreas transplantation on diabetes related complication and patient survival. Islet cell transplantation has recently emerged as one the most promising therapeutic approaches to improving glycometabolic control in type 1 diabetic patients and, in many cases, to obtaining insulin independence. Islet cell transplantation requires a relatively short hospital stay and has the advantage of being a relatively noninvasive procedure. The rate of insulin independence 1 year after islet cell transplantation has significantly improved in recent years Data from a recent international Trial confirmed that islet cell transplantation can be potentially a cure for type 1 diabetes. Recent data indicate that insulin independence after islet cell transplantation is associated with an improvement in glucose metabolism and quality of life and with a reduction in hypoglycemic episodes. Islet cell transplantation is still in its initial stages, and many obstacles still need to be overcome. Once clinical islet transplantation has been successfully established, this treatment could even be offered to diabetic patients long before the onset of diabetic complications or to patients with life-threatening hypoglycemic unawareness and brittle diabetes.

Insulin-induced hypoglycemia occurs commonly in intensively treated patients with type 1 diabetes, but the cardiovascular consequences of hypoglycemia in these patients are not known. We studied left ventricular systolic [left ventricular ejection fraction (LVEF)] and diastolic [peak filling rate (PFR)] function by equilibrium radionuclide angiography during insulin infusion (12 pmol · kg−1 · min−1) under either hypoglycemic (∼2.8 mmol/l) or euglycemic (∼5 mmol/l) conditions in intensively treated patients with type 1 diabetes and healthy nondiabetic subjects ( n = 9 for each). During hypoglycemic hyperinsulinemia, there were significant increases in LVEF (ΔLVEF = 11 ± 2%) and PFR [ΔPFR = 0.88 ± 0.18 end diastolic volume (EDV)/s] in diabetic subjects as well as in the nondiabetic group (ΔLVEF = 13 ± 2%; ΔPFR = 0.79 ± 0.17 EDV/s). The increases in LVEF and PFR were comparable overall but occurred earlier in the nondiabetic group. A blunted increase in plasma catecholamine, cortisol, and glucagon concentrations occurred in response to hypoglycemia in the diabetic subjects. During euglycemic hyperinsulinemia, LVEF also increased in both the diabetic (ΔLVEF = 7 ± 1%) and nondiabetic (ΔLVEF = 4 ± 2%) groups, but PFR increased only in the diabetic group. In the comparison of the responses to hypoglycemic and euglycemic hyperinsulinemia, only the nondiabetic group had greater augmentation of LVEF, PFR, and cardiac output in the hypoglycemic study ( P < 0.05 for each). Thus intensively treated type 1 diabetic patients demonstrate delayed augmentation of ventricular function during moderate insulin-induced hypoglycemia. Although diabetic subjects have a more pronounced cardiac response to hyperinsulinemia per se than nondiabetic subjects, their response to hypoglycemia is blunted.

Abstract Background Dental caries and type 1 diabetes are responsible for a large burden of global disease; however, the exact prevalence of dental caries among children and adolescents with type 1 diabetes remains controversial, and no quantitative meta-analysis exists. Thus, we performed a meta-analysis to evaluate the prevalence of dental caries among children and adolescents with type 1 diabetes. Methods We performed a systematic search strategy using PubMed, EMBASE and China National Knowledge Infrastructure for relevant studies investigating the prevalence of dental caries in children and adolescents with type 1 diabetes from July 1971 until December 2018. The pooled prevalence with 95% confidence intervals (95%CIs) and subgroup analyses were calculated using a random effects model. Results After screening 358 non-duplicated articles, a total of 10 articles involving 538 individuals were included. The overall prevalence of dental caries among children and adolescents with type 1 diabetes was 67% (95% CI: 0.56–0.77%; I2 = 83%). The prevalence was highest in South America (84%) and lowest in diabetic patients with good metabolic control (47%). Conclusions The prevalence of dental caries was high among children and adolescents with type 1 diabetes. Screening and preventive treatment should be included in dental clinical routines for diabetic children and adolescents, especially in those with poor metabolic control.

Abstract Objectives: The aim of the study was to calculate the prevalence rates and risk ofappearance of cutaneous lesions in diabetic patients with both type-1 and type-2diabetes. Material and Method: 384 patients were analysed, of which 47 had type-1diabetes (T1DM), 140 had type-2 diabetes (T2DM) and 197 were non-diabeticcontrols. Results: The prevalence of the skin lesions considered markers of diabeteswas 57.75% in diabetics, in comparison to 8.12% in non-diabetics (p<0.01). The riskof skin lesion appearance is over 7 times higher in diabetic patients than in nondiabetics.In type-1 diabetes the prevalence of skin lesions was significantly higherthan in type-2 diabetes, and the risk of skin lesion appearance is almost 1.5 timeshigher in type-1 diabetes than type-2 diabetes compared to non-diabetic controls.Conclusions: The diabetic patients are more susceptible than non-diabetics todevelop specific skin diseases. Patients with type-1 diabetes are more affected.

The target molecules of the T-cell response in type 1 diabetes, despite their pathogenic importance, remain largely uncharacterized, especially in humans. Interestingly, molecules such as insulin and glutamic acid decarboxylase (GAD) have been shown to be a target not only of autoantibodies, but also of autoreactive T-lymphocytes both in man and in the non-obese diabetic (NOD) mouse. In the present study we aimed to determine the existence of a specific T-cell response towards the insulinoma-associated protein 2 (IA-2) islet tyrosine phosphatase, a recently identified autoantigen which is the target of autoantibodies strongly associated with diabetes development. Human recombinant IA-2 produced in Escherichia coli, was tested for its reactivity with peripheral blood lymphocytes obtained from 16 newly diagnosed type 1 diabetic patients and from 25 normal controls, 15 of whom were HLA-DR-matched. A T-cell proliferation assay was performed in triplicate employing freshly isolated cells in the absence or in the presence of the antigen to be tested (at two different concentrations: 2 microg/ml and 10 microg/ml). A specific T-cell proliferation (defined as a stimulation index (S.I.) >/=3) was observed against IA-2 used at a concentration of 10 microg/ml (but not of 2 microg/ml) in 8/16 diabetic patients, in 1/15 HLA-DR-matched control subjects (P<0.01 by Fisher exact test) and in 0/10 of the remaining normal individuals. A statistically significant difference (P<0.003 by Mann-Whitney U test) was also observed in S.I. values between patients (3.1+/-1.4) and HLA-DR-matched controls (1.7+/-0.54) employing IA-2 at a concentration of 10 microg/ml. However, when IA-2 was used at a concentration of 2 microg/ml, the difference in S. I. between patients (1.65+/-0.8) and controls (1.0+/-0.3) did not reach statistical significance. In conclusion, these data show the presence of a specific, dose-dependent T-lymphocyte response against the IA-2 islet tyrosine phosphatase at the onset of type 1 diabetes. Consequently, this molecule appears to be a target not only at the B-lymphocyte but also at the T-lymphocyte level, reinforcing the potential pathogenic role of this autoantigen in the islet destructive process.
