Cases of extracorporeal membrane oxygenation (ECMO) bridged lung transplantation (LTx) are rare in Japan because an allocation system to prioritize patients based on urgency remains to be established. For critically ill patients who cannot wait for a brain-dead donor LTx, ECMO bridge to living-donor LTx may be the only practical option. A 21-year-old woman with pleuroparenchymal fibroelastosis after hematopoietic stem cell transplantation was admitted to our hospital with rapidly progressive respiratory failure...

INTRODUCTION: Kidney transplant donors lose 50% of their renal mass after nephrectomy. The remaining kidney compensates for this loss and it is estimated that 70% of the baseline renal function prior to donation is recovered. Factors associated with post-donation renal compensation are not well understood. METHODS: Retrospective study of 66 consecutive kidney donors (mean age 48.8 years, 74.2% women). We analysed the potential factors associated with the compensatory mechanisms of the remaining kidney by comparing donors according to their renal compensation rate (RCR) (Group A, infra-compensation [<70%]; Group B, normal compensation [>70%])...

BACKGROUND/AIM: In clinical research setting, accurate and precise measurement of glomerular filtration rate (GFR) is essential to overcome the limitations of GFR estimation with equations, which are often unreliable. In recent decades, a method for measuring GFR by plasma clearance of iohexol, a non-ionic radiocontrast agent, was developed. To evaluate the safety of the procedure, we aimed to review all immediate adverse reactions that could be related to iohexol administration in our group's 25 years worth of experience...

BACKGROUND: The shortage of organs for kidney transplantation for patients with end-stage renal disease (ESRD) is magnified in Hispanics/Latin Americans in the United States. Living donor kidney transplantation (LDKT) is the treatment of choice for ESRD. However, compared to their representation on the transplant waitlist, fewer Hispanics receive a LDKT than non-Hispanic whites. Barriers to LDKT for Hispanics include: lack of knowledge, cultural concerns, and language barriers. Few interventions have been designed to reduce LDKT disparities...

BACKGROUND: Portopulmonary hypertension (POPH) is characterized by pulmonary vasoconstriction, while hepatopulmonary syndrome (HPS) is characterized by vasodilation. Definite POPH is a risk factor for the survival after orthotopic liver transplantation (OLT), as the congestive pressure affects the grafted liver, while subclinical pulmonary hypertension (PH) has been acknowledged as a non-risk factor for deceased donor OLT. Given that PH measurement requires cardiac catheterization, the tricuspid regurgitation pressure gradient (TRPG) measured by echocardiography is used to screen for PH and congestive pressure to the liver...

Live kidney donation involves a delicate balance between saving the most lives possible and maintaining a transplant system that is fair to the many thousands of patients on the transplant waiting list. Federal law and regulations require that kidney allocation be equitable, but the pressure to save patients subject to ever-lengthening waiting times for a transplant has been swinging the balance toward optimizing utility at the expense of justice. This article traces the progression of innovations created to make optimum use of a patient's own live donors...

Carbon monoxide is widely acknowledged as an important gasotransmitter in the mammalian system with importance on par with that of nitric oxide. It has also been firmly established as a potential therapeutic agent with a wide range of indications including organ transplantation, cancer, bacterial infection, and inflammation-related conditions such as colitis and sepsis. One major issue in developing CO based therapeutics is its delivery in a pharmaceutically acceptable form. Currently, there are generally five forms of deliveries: inhaled CO, photosensitive CO-releasing molecules, encapsulated CO, CO dissolved in drinks, and molecules that would release CO under physiological conditions without the need for light...

LT is a practical therapeutic alternative for unresectable hepatoblastoma; however, deciding when to perform LT is difficult. The aim of this study was to optimize the timing of LT for hepatoblastoma using pretransplant trends in AFP levels. Trends in pretransplant AFP levels and their influence on post-transplant outcomes were retrospectively evaluated. All patients who underwent living donor LT for hepatoblastoma in our institution since 2002 were included. Variables analyzed included history of prior tumor resection, pretransplant AFP responses to chemotherapy, metastatic disease at diagnosis, and post-transplant chemotherapy...

Recent OPTN bylaw revisions mandate US transplant programs have an "approved pediatric component" in order to perform heart transplantation (HT) in patients <18 years old. The impact of this change on adolescents, a group known to be at high-risk for graft loss and nonadherence, is unknown. We studied all US pediatric (age <18 years) HT from 2000-2015 to compare graft survival between centers organized primarily for adult versus pediatric care. Centers were designated as pediatric- or adult-specialty care according to the ratio of pediatric:adult HT performed and minimum age of HT (pediatric-specialty defined as ratio>0...

De novo donor specific antibody (DSA) formation is a major problem in transplantation, and associated with long-term graft decline and loss as well as sensitisation, limiting future transplant options. Forming high-affinity, long-lived antibody responses involves a process called the germinal center (GC) reaction, and requires interaction between several cell types, including GC B cells, T follicular helper (Tfh) and T follicular regulatory (Tfr) cells. Tfr cells are an essential component of the GC reaction, limiting its size and reducing nonspecific or self-reactive responses...

Background: Current reliance on clinical, laboratory and Doppler ultrasound (DUS) parameters for monitoring kidney transplant perfusion in the immediate post-operative period in children risks late recognition of allograft hypoperfusion and vascular complications. Near-infrared spectroscopy (NIRS) is a real-time, non-invasive technique for monitoring tissue oxygenation percutaneously. NIRS monitoring of kidney transplant perfusion has not previously been validated to the gold standard of DUS...

Hematopoietic stem cell biology has focused on stem cell purification and the definition of the regulation of purified stem cells in a hierarchical system. Work on the whole unpurified murine marrow cell population has indicated that a significant number of hematopoietic stem cells, rather than being dormant, are actively cycling, always changing phenotype and therefore resistant to purification efforts by current approaches. The bulk of cycling marrow stem cells are discarded with the standard lineage negative, stem cell marker positive separations...

Organ transplantation has prolonged and improved the lives of many patients around the world. However, a widespread shortage of donors remains the main factor that has led to organ trafficking and transplant tourism. To stop transplant tourism and to provide optimal treatment for its citizens with end-stage renal disease, Montenegro started performing renal transplantations in September 2012. Thirty-five transplantations have been performed since that time, 34 from living donors and only 1 from a deceased donor...

OBJECTIVE: Hepatic artery thrombosis (HAT) is one of the most serious complications of liver transplantation that can potentially lead to loss of the allograft. Retransplantation is the only option when revascularization can't be performed but the donor may be not available in the short period of time. We report the technique of using portal vein arterialization (PVA) for bridging before retransplantation. There are few reports in living donor setting. CASE DESCRIPTION: The recipient of the liver was a 59 year old male who received an extended right lobe graft from his son...
