Background: Mesenchymal stem cell infusion and vitamin D supplementation may have immunomodulatory actions that could prolong the preservation of residual insulin secretion in patients with type 1 diabetes (T1D). Intervention with these agents after onset of T1D could favor the development of a remission phase, with potential clinical impact. We aimed to compare the presence of clinical remission (CR), glycemic control and daily insulin requirement at 6, 12, 18, 24 and 36 months after the diagnosis of T1D using IDAA1c in patients who received therapy with adipose tissue-derived mesenchymal stem cell (ASC) infusion and vitamin D supplementation and a control group.

To evaluate safety and therapeutic effect along 12 months of allogenic adipose tissue-derived stromal/stem cells (ASCs) transplantation with cholecalciferol (VITD) in patients with recent-onset type 1 diabetes (T1D). Prospective, phase II, open trial, pilot study in which patients with recent onset T1D received ASCs (1xKgx10 cells) and VITD 2000UI/day for 12 months (group 1) and were compared to controls with standard insulin therapy (group 2). Adverse events, C-peptide area under the curve (CPAUC), insulin dose, HbA1c and frequency of FoxP3+ in CD4+ or CD8+ T-cells(flow cytometry) were evaluated at baseline(T0), after 3(T3), 6(T6) and 12 months(T12).

Objective: Adipose tissue-derived stromal/stem cells (ASCs) and vitamin D have immunomodulatory actions that could be useful for type 1 diabetes (T1D). We aimed in this study to investigate the safety and efficacy of ASCs + daily cholecalciferol (VIT D) for 6 months in patients with recent-onset T1D.

Methods: In this prospective, dual-center, open trial, patients with recent onset T1D received one dose of allogenic ASC (1 × 10 cells/kg) and cholecalciferol 2,000 UI/day for 6 months (group 1).

To evaluate the short term safety and potential therapeutic effect of allogenic adipose tissue-derived stromal/stem cells (ASCs) + cholecalciferol in patients with recent-onset T1D. Prospective, phase II, open trial, pilot study in which patients with recent onset T1D received ASCs (1 × 10 cells/kg) and cholecalciferol 2000 UI/day for 3 months (group 1) and were compared to controls with standard insulin therapy (group 2). Adverse events, C-peptide (CP), insulin dose, HbA1c, time in range (TIR), glucose variability (continuous glucose monitoring) and frequency of CD4FoxP3+ T-cells (flow cytometry) were evaluated at baseline (T0) and after 3 months (T3).

Objective: Zinc transporter 8 autoantibodies (ZnT8A) have been poorly studied in non-Caucasian individuals. We aimed to investigate the prevalence of ZnT8 autoantibodies in patients with T1D and their first degree relatives (FDR) from a multiethnic population, as well as its relation with the insulin (INS) or the protein tyrosine phosphatase non-receptor 22 (PTPN22) gene polymorphisms.

Subjects And Methods: ZnT8A were analyzed in sera from T1D patients (n = 72, mean age of 30.

Unlabelled: Previous gestational diabetes mellitus (pGDM) indicates future risk for type 2 diabetes (T2DM). Insulin resistance (IR) may precede T2DM in many years and is associated with an increased risk for cardiovascular diseases.

Aim: This study aims to identify endothelial dysfunction and cardiovascular risk factors in women with pGDM.

Background: Familial partial lipodystrophies (FPLD) are clinically heterogeneous disorders characterized by selective loss of adipose tissue, insulin resistance and metabolic complications. Until genetic studies become available for clinical practice, clinical suspicion and pattern of fat loss are the only parameters leading clinicians to consider the diagnosis. The objective of this study was to compare body composition by dual energy X-ray absorptiometry (DXA) in patients with FPLD and control subjects, aiming to find objective variables for evaluation of FPLD.

Controversy exists regarding the effect of pregnancy on the development and course of diabetic nephropathy. This study followed 43 pregnant women with previous diabetes mellitus, 32 without nephropathy (Group I) and 11 with nephropathy (Group II). Urinary albumin excretion (UAE), serum creatinine (Cr) and creatinine clearance (CCr) in the pre-pregnancy (Pre-P), first trimester (1T), third trimester (3T) and 1 year postpartum (PP) were evaluated.

Type 1 diabetes is a chronic disease characterized by progressive destruction of the pancreatic beta cells, what leads to insulin deficiency and hyperglycemia. However, a significant secretory function may persist for long periods in a few patients, what is clinically evident through the detection of serum C peptide. This phenomenon might reduce the risk of chronic complications, severe hypoglycemias and allow easier metabolic control.

Diabetic ketoacidosis is an acute complication of Diabetes Mellitus characterized by hyperglycemia, metabolic acidosis, dehydration, and ketosis, in patients with profound insulin deficiency. It occurs predominantly in patients with type 1 diabetes and is frequently precipitated by infections, insulin withdrawal or undiagnosed type 1 diabetes. The authors review its pathophysiology, diagnostic criteria and treatment options in adults, as well as its complications.

Article Synopsis
  • A subgroup of patients may present diabetic ketoacidosis at the start of diabetes but later be categorized as type 2 diabetes based on follow-up.
  • These patients, often obese and of African or Hispanic descent, test negative for auto-antibodies linked to type 1 diabetes but often show specific HLA class II genetic markers.
  • The text discusses a case of a Caucasian patient who experienced this shift and was able to discontinue insulin therapy, exploring factors that contributed to this positive outcome.

Type 1 diabetes (T1D) is characterized by an immuno-mediated progressive destruction of the pancreatic beta cells. Due to the ability of NK cells to kill target cells as well as to interact with antigen-presenting and T cells, it has been suggested that they could be involved in one or multiple steps of the immune-mediated attack that leads to T1D. Abnormalities in the frequency and activity of NK cells have been described both in animal models and patients with T1D.
