Pancreas transplantation improves the quality of life of Japanese type 1 diabetes patients with diabetic kidney disease.

Objectives: Type 1 diabetes mellitus (T1DM) patients with diabetic kidney disease-induced kidney failure have a significantly impaired quality of life (QOL), resulting in a high level of physical, mental, and social anxiety. In this study, we evaluated the QOL of T1DM patients on the list for pancreas transplantation (PTx) at their registration, and determined whether PTx improved their QOL.

Methods: There were 58 patients (men/women, 22/36; mean age, 42.

Impact of B Cell Depletion on COVID-19 in Kidney Transplant Recipients.

Kidney transplant recipients are patients at high risk for coronavirus disease 2019 (COVID-19) due to being on immunosuppressive therapy. B cell depletion therapy, including rituximab, is an important strategy for ABO-incompatible transplants. However, knowledge about the effect of B cell depletion therapy on COVID-19 is lacking.

An Examination of Packing Methods for Grafts to Prevent Freezing Injury during Transportation for Liver Transplantation.

Background: University of Wisconsin solution (UW) may freeze at temperatures below -0.7 °C, damaging the graft. The present study assessed the effectiveness of the liver graft package protocol, which recommends filling a package with sufficient liquid to prevent grafts from sustaining freezing injury.

Outcomes of Pancreas Transplantation for Lower-Ranked Candidates.

Methods: Sixty-five cases of pancreatic transplantation from brain-dead donors, which were performed in our facility, were enrolled in this study.

Evaluation of the Efficacy and Effects of Common Hepatic Artery Reconstruction in Pancreas Transplantation: A Randomized Controlled Trial.

Maintenance of postoperative graft flow is important in pancreas transplantation. In Japan, reconstruction of the common hepatic artery is performed primarily to increase perfusion in the pancreatic head. We investigated the effects of common hepatic artery reconstruction on patient and graft survival and endocrine functions.

The History of Clinical Islet Transplantation in Japan.

Islet transplantation shows the promise of being capable of relieving glucose instability and improving QOL of patients with type 1 diabetes that cannot be controlled due to severe hypoglycemia unawareness. In Japan, following the first human islet isolation from a donor after cardiac death in 2003 and the first clinical islet transplantation in 2004, islet transplantation was performed for the improvement of type 1 diabetes as a single-center trial in several centers. Although it was discontinued due to the possibility of contamination of collagenase by bovine brain component in 2007, the phase II clinical trial of islet transplantation started using ATG induction and a TNF-α inhibition protocol in 2012.

Analysis of risk factors for donation after circulatory death kidney transplantation in Japan.

Background: In Japan, donations after circulatory death kidney transplantation are widely performed due to legislation delays. The number of donations after brain death kidney transplantations is increasing, but the target remains unmet. We reviewed the outcomes of donation after circulatory death in Japan.

Outcomes of pancreas transplantation in older versus younger recipients: a comparative analysis.

Purpose: The feasibility of pancreas transplantation (PT) in older recipients remains a matter of debate. We examined the influence of recipient age on PT outcomes and identified the prognostic factors for older recipients.

Methods: We compared the outcomes of PT in recipients aged < 50 years (younger group; n = 285) with those in recipients aged ≥ 50 years (older group; n = 94).

Impact of the revision of the law on pancreatic transplants in Japan-An analysis of the Japanese Pancreas Transplants Registry.

Background: In Japan, it has been about 10 years since the revision of the law on donating brain-dead organs. The present study compared the outcomes of pancreatic transplant before and after the revision of the law.

Methods: The 437 patients who had received pancreas transplantation were divided into two groups according to the time when pancreas transplantation was performed between era 1 (before the revision) and 2 (after the revision), and compared in the patient and pancreas graft survival.

Impact of Pancreas Transplantation on the Patient Survival-An Analysis of the Japanese Pancreas Transplants Registry.

Background: The impact of pancreas transplantation, including kidney transplantation on patients' life prognoses, is unclear in Japan. An analysis of the data of the Japan Pancreas Transplant Registry was performed to compare the patient survival between on the waiting list and after pancreas transplantation, and investigate the factors that affect the patient survival after pancreatic transplantation.

Methods: The life prognoses of 361 patients who underwent pancreas transplantation from 2000 to December 2018 were examined.

Are the outcomes of Japanese pancreas transplantation utilizing extended-criteria donors acceptable? A propensity score matching analysis for donors <50 or ≥50 years old.

In Japan, about 30% of pancreatic transplant donors are ≥50 years old, making them "extended-criteria donors (ECDs)." We analyzed 361 cases of transplantation involving donors from the Japanese pancreas transplantation registry to evaluate the acceptability of ECDs. The patient survival rates at 1, 5, and 10 years after transplantation were 96.

[A Case of Gastric Cancer with Necrotic Lymph Node Perforation in the Stomach during Chemotherapy].

A 63-year-old man was diagnosed with gastric cancer. Distal gastrectomywas performed in November 2011. The pathologic finding was pT3N2M0, Stage ⅢA.

The Effects of Using Pancreases Obtained from Brain-Dead Donors for Clinical Islet Transplantation in Japan.

Background: The pool of brain-dead donors (BDDs) was increased with the revision to the relevant law in 2010, and islet transplantation from BDDs was started in 2013. The present study assessed the influence of using pancreases from BDDs on islet transplantation in Japan.

Renal Autotransplantation and Extracorporeal Nephron-Sparing Surgery for De Novo Renal Cell Carcinoma in a Kidney Allograft.

De novo renal cell carcinoma (RCC) rarely occurs in kidney allografts; however, the risk of RCC in these patients is 100-fold that of the general healthy population. Although total nephrectomy has been the standard treatment for kidney allograft RCC, several authors have reported that early-stage RCC in kidney allografts was successfully treated with nephron-sparing surgery. We herein describe a new procedure involving renal autotransplantation and extracorporeal nephron-sparing surgery, which was performed to treat de novo RCC near the hilum of a transplanted kidney.
