Children with single ventricle physiology have complete mixing of the pulmonary and systemic circulations, requiring staged procedures to achieve a separation of these circulations, or Fontan circulation. The single ventricle physiology significantly increases the risk of mortality in children undergoing non-cardiac surgery. As liver transplantation for patients with single ventricle physiology is particularly challenging, only a few reports have been published. We herein report a case of successful LDLTx for an 8-month-old pediatric patient with biliary atresia, heterotaxy, and complex heart disease of single ventricle physiology...

Interactions between bacteria and bacteriophage viruses (phages) are known to influence pathogen growth and virulence, microbial diversity, and even biogeochemical cycling. Lytic phages in particular infect and lyse their host cells, and can therefore have significant effects on cell densities as well as competitive dynamics within microbial communities. Despite the known impacts of lytic phages on the ecology and evolution of bacteria in free-living communities, little is known about the role of lytic phages in host-associated microbiomes...

In renal transplantation, living donations have more significant benefits compared to cadaveric donations. However, a probable increase in blood pressure following donation should also be kept in mind. In this study, we investigated the long-term changes in blood pressure in living kidney donors using ambulatory blood pressure monitoring and we explored the e-GFR and albuminuria/proteinuria measurements at three time points. Twenty-eight living kidney donors and 39 healthy individuals were evaluated and compared at the baseline and later at the 10th year...

INTRODUCTION: Acute liver failure (ALF) is an indication for emergency liver transplantation (LT). Although centers performing only deceased donor liver transplants (DDLT) have shown improved outcomes in this situation, they still have relatively long waiting lists. An alternative would be living donor liver transplantation (LDLT), which has shown equivalent outcomes in the elective situation but there is limited evidence of its results in ALF. AIM: The purpose of this study was to assess the outcomes in patients with ALF undergoing emergency LDLT in our center in Delhi, India...

Mild Zellweger spectrum disorder, also described as Infantile Refsum disease, is attributable to mutations in PEX genes. Its clinical course is characterized by progressive hearing and vision loss, and neurodevelopmental regression. Supportive management is currently considered the standard of care, as no treatment has shown clinical benefits. LT was shown to correct levels of circulating toxic metabolites, partly responsible for chronic neurological impairment. Of three patients having undergone LT for mild ZSD, one died after LT, while the other two displayed significant neurodevelopmental improvement on both the long-term (17 years post-LT) and short-term (9 months post-LT) follow-up...

BACKGROUND: The significance of pre-operative body composition has recently attracted much attention in various diseases. However, cut-off values for these parameters remain undetermined, and these factors are not currently included in selection criteria for recipients of living donor liver transplantation (LDLT). METHODS: Using computed tomography of 657 donors for LDLT, skeletal muscle mass, muscle quality, and visceral adiposity were evaluated by using skeletal muscle mass index (SMI), intramuscular adipose tissue content (IMAC), and visceral-to-subcutaneous adipose tissue area ratio (VSR)...

BACKGROUND & AIMS: Living-donor liver transplantation (LDLT) can simultaneously cure hepatocellular carcinoma (HCC) and underlying liver cirrhosis, improving long-term results in patients with HCC. ABO-incompatible LDLT could expand the living-donor pool, reduce waiting times for deceased-donor liver transplantation, and improve long-term survival for some patients with HCC. METHODS: We retrospectively reviewed the medical records of patients undergoing LDLT for HCC from November 2008 to December 2015 at a single institution in Korea...

Kidney transplant is the optimal therapy for end stage renal disease, prolonging survival and reducing healthcare spending. Prior economic analyses of kidney transplant using Markov models, have generally assumed compatible, low risk, donors. The economic implications of using deceased donor kidneys with high kidney donor profile index (KPDI) scores, ABO incompatible or HLA incompatible living donors has not been assessed. The costs of transplant and dialysis were compared using discrete event simulation over a 10-year period, using data from the United States Renal Data System, Vizient ™ (Irving, Texas), and literature review...

Background: Although many previous studies have confirmed that perioperative blood transfusion is associated with poor outcomes after liver transplantation (LT), few studies described the influence of single-donor platelet apheresis transfusion in living donor LT (LDLT). This study aimed to assess the effect of blood products on outcomes for LDLT recipients, focusing on apheresis platelets. Methods: This retrospective study included 126 recipients who underwent their first adult-to-adult LDLT...

BACKGROUND: Utilization of liver grafts from hepatitis B core antibody (anti-HBc) positive donors carries the risk of reactivation of hepatitis B virus (HBV) in recipients because of post-transplant immunosuppressive therapy. METHODS: This was a retrospective study of patients who had received liver grafts from anti-HBc positive live donors between 2006 and 2016 at our institute. RESULTS: Out of 22 recipients [all males, mean age 45.4 years (range 18-64 years)], four patients were hepatitis B surface antigen (HBsAg) positive preoperatively and received entecavir post-transplantation...

We previously developed a mobile- and web-based decision aid (iChoose Kidney) that displays individualized risk estimates of survival and mortality, for the treatment modalities of dialysis versus kidney transplantation. We examined the effect of iChoose Kidney on change in transplant knowledge and access to transplant in a randomized controlled trial among patients presenting for evaluation in three transplant centers. A total of 470 patients were randomized to standard transplantation education (control) or standard education plus iChoose Kidney (intervention)...

BACKGROUND: Posttransplant liver graft failure occurs most often in male recipients of livers from female donors. The respective role of donor sex itself and the size disparity in graft vessels/bile ducts according to donor sex are unclear. Thus, we aimed to evaluate the importance of donor sex with adjustment for anastomotic size disparity between female and male donor grafts. METHODS: A total of 309 male patients without hepatic tumors who underwent living donor liver transplantation were analyzed (109 female and 200 male donors)...

BACKGROUND: At present, organ transplantation is the most efficient treatment of end-stage failure of various organs, including the heart, lungs, pancreas, intestines, kidney, and liver. Despite the efforts to use organs from living donors or from donors after circulatory death, most of the organs are recovered from brain dead (BD) donors. METHODS: The Medline and Web of Science databases were searched without time limit on November 2015 using the terms "brain dead donor" and "deceased donor" in conjunction with "transplantation", "graft", "organ", "hemodynamic", "hormonal", or "management"...

Living donation provides important access to organ transplantation, which is the optimal therapy for patients with end-stage liver or kidney failure. Paired exchanges have facilitated thousands of kidney transplants and enable transplantation when the donor and recipient are incompatible. However, frequently willing and otherwise healthy donors have contraindications to donation of the organ that their recipient needs. Trans-organ paired exchanges would enable a donor associated with a kidney recipient to donate a lobe of liver and a donor associated with a liver recipient to donate a kidney...

Kidney paired donation (KPD) can facilitate living donor transplantation for candidates with an incompatible donor, but requires waiting for a match while suffering the morbidity of dialysis. The balance between waiting for KPD versus desensitization or deceased donor transplantation relies on the ability to estimate KPD wait times. We studied donor/candidate pairs in the National Kidney Registry (NKR), a large multi-center KPD clearinghouse, between 10/2011-9/2015 using a competing risk framework. Among 1894 candidates, 52% were male, median age was 50 years, 66% were white, 59% had blood type O, 42% had PRA>80, and 50% obtained KPD through NKR...

AIM: Careful assessment of the potential donor-recipient relationship is recommended by guidelines to prevent undue coercion, and ensure realistic expectations and genuine motivations. However, relationships are complex, nuanced and value-laden, and can be challenging to evaluate in living kidney donation. We aimed to describe the attitudes and approaches of transplant clinicians towards assessing the relationship between potential living kidney donors and their recipients. METHODS: Semi-structured interviews were conducted with 54 transplant clinicians (nephrologists, surgeons, coordinators, social workers, psychiatrists and psychologists) from 32 transplant centres across nine countries including Australia, United States, Canada and New Zealand...
