FDA Panel Endorses Islet Cell Treatment for Type 1 Diabetes FDA Panel Endorses Islet Cell Treatment for Type 1 Diabetes

Voting 12-4 to support approval, panel members expressed concern about toxicity of long-term immunosuppression, particularly given the advances in diabetes technology that now offer improved control.Medscape Medical News

The inheritance of variants that lead to coding changes in, or the mis-expression of, genes critical to pancreatic beta cell function can lead to alterations in insulin secretion and increase the risk of both type 1 and type 2 diabetes. Recently developed clustered regularly interspaced short palindromic repeats (CRISPR/Cas9) gene editing tools provide a powerful means of understanding the impact of identified variants on cell function, growth, and survival and might ultimately provide a means, most likely after the transplantation of genetically “corrected” cells, of treating the disease. Here, we review some ...

Objectives We aimed to determine whether responsive insulin-producing cells (IPCs) could be generated from adipose-derived stem cells (ADSCs) isolated from patients with type 1 diabetes mellitus (T1DM). Methods We isolated ADSCs from adipose tissue of 4 patients (one patient with T1DM and 3 nondiabetic patients), who underwent surgery and differentiated them into IPCs with using a 2-step xeno-antigen free, 3-dimensional culture method. Characteristics of isolated ADSCs, in vitro cell quality, programmed cell death ligand-1 (PDL-1) expression, and transplantation into streptozotocin induced diabetic nude mice were inve...

Abstract Pancreatic islet transplantation is a reliable approach for treating insulin-deficient diabetes. This established β-cell replacement approach has shown considerable improvements in the last 2 decades. It has helped achieve metabolic homeostasis and safe outcomes for a subset of patients with type 1 diabetes and severe pancreatitis. Nutrition support, until recently, was considered as a secondary factor, merely identified as a means of providing all the necessary nutrients for such patients. However, new literature suggests that several factors, such as the route, timing, quantity, and composition of ...

Although both pancreas transplantation alone (PTA) and islet cell transplantation (ICT) have been associated with perioperative declines in estimated glomerular filtration rate (eGFR), the magnitude of decline is far less than that associated with medically managed (MM) diabetes. In the long-term, PTA and ICT have demonstrated stabilization of chronic kidney disease (CKD) for type 1 diabetic patients. In this setting, it remains unclear whether transplantation reduces the future need for kidney transplantation and mortality.

In conclusion, it remains unclear if brain-specific regional and temporal changes occur in the expression of the different APP variants during AD progression. Since APP is also found in blood cells, assessing the changes in APP mRNA expression in peripheral blood cells from AD patients has been considering an alternative. However, again the quantification of APP mRNA in peripheral blood cells has generated controversial results. Brain APP protein has been analyzed in only a few studies, probably as it is difficult to interpret the complex pattern of APP variants and fragments. We previously characterized the soluabl...

Conclusions. Human islet isolates with insufficient beta-cell mass for implantation within 72 hours can be cultured for 96 hours and longer to combine multiple preparations in order to reach the desired beta-cell dose and therefore result in a better metabolic benefit.

Abstract A combined kidney and pancreas transplant is a therapeutic option for patients with type 1 diabetes and end-stage renal disease. After successful transplantation, fertility is rapidly restored, allowing women of childbearing age to have spontaneous pregnancies and men to father pregnancies. These pregnancies are at increased risk for maternal and neonatal adverse outcomes due to immunosuppressive therapy, comorbidities, previous type 1 diabetes and previous transplant surgery, although the majority ends with the birth of a live and healthy offspring. Hypertension, miscarriages, diabetes, infections, graft...

Purpose of review Human islet transplantation has proven to be a highly effective treatment for patients with labile type 1 diabetes mellitus, which can free patients from daily glucose monitoring and insulin injections. However, the shortage of islet donors limits its’ broad application. Porcine islet xenotransplantation presents a solution to the donor shortage and recent advances in genetic modification and immunosuppressive regimens provide renewed enthusiasm for the potential of this treatment. Recent findings Advances in genetic editing technology are leading to multigene modified porcine islet donors with...

AbstractWhole-organ pancreas and islet transplantations are performed in a highly selected group of patients with diabetes mellitus, primarily those with type 1 diabetes mellitus, complicated by recurrent severe hypoglycaemia or renal failure requiring kidney transplantation. Clinical accessibility to pancreases or islets, and patient characteristics and therapeutic goals, may dictate choice of procedure. Pancreas transplantation is most often performed simultaneous with a kidney transplant, but patients with particularly labile type 1 diabetes may be considered for a pancreas transplant alone. While highly successful at r...
