OBJECTIVES: Survival in liver transplant after end-stage liver disease is associated with major cardiac functions. In a significant number of patients with end-stage liver disease, cardiac dysfunctions may be observed, which can include high-output heart failure, cardiac valve disease, and pulmonary venous and arterial hypertension. All of these affect perioperative survival. The aim of our study was to determine whether preoperative and postoperative echocardiographic parameters, specifically right heart-related tricuspid regurgitation, estimated systolic pulmonary arterial pressure, and tricuspid annular plane systolic excursion, are associated with rejection and mortality in liver transplant patients...

The risk of de novo hepatitis B virus infection is lower after liver transplant using hepatitis B core antibody-negative donors into negative recipients versus hepatitis B core antibody-positive donors but can occur. Here, we present a 34-year-old male patient with acute de novo hepatitis B virus that developed 7 months after successful liver transplant. The case we report here is the first in the literature with regard to both switch from tenofovir to entecavir treatment and the presentation of de novo acute hepatitis B virus after liver transplant...

Liver transplant has occasionally been performed in the presence of congenital afibrinogenemia and has been rarely used to treat it. Historically, to safely manage coagulopathy during transplant, these patients have been administered a combination of fresh frozen plasma and cryoprecipitate. In this case report, we discuss the first reported use of recombinant fibrinogen to treat such a patient and the decision-making process considered to balance the thrombotic and hemorrhagic risks.

Polyomavirus-associated nephropathy is a pertinent cause of poor renal allograft survival. Absence of defensive immunity toward BK polyomavirus may favor the occurrence of BK polyomavirus-active infection and influence the progression to polyomavirus-associated nephropathy. Humoral immune responses may offer incomplete protection. In this review, available data on both humoral and cellular immunity were examined, with a concentration on BK polyomavirus-specific T cells; in addition, their roles in BK polyomavirus cellular immune response and immunotherapy were discussed...

OBJECTIVES: Infections are major causes of morbidity and mortality in the early postoperative period after liver transplant. We observed a high rate of enterococcal infections at our center. Therefore, we added an intraoperative single shot of vancomycin to the standard regimen of meropenem given over 5 days. The aim of this study was to determine the prevalence of both Enterococcus faecium and Enterococcus faecalis infections during the first 28 days after surgery depending on the type of antibiotic prophylaxis and their implications on mortality and morbidity...

REVIEW
Gengguo Deng, Dong Liu
Organ shortage has long been an obstacle to transplant procedures. As acceptance of aging kidneys from expanded criteria donors increases, the long-term outcomes of renal allografts could be unsatisfactory. The klotho gene, which is known as an antiaging gene that is highly expressed in kidneys, is closely associated with chronic kidney disease and acute kidney injury. Results from existing literature have shown a tendency to support Klotho as a renal protective protein owing to its pleiotropic effects. However, few data are available on Klotho in renal transplant...

OBJECTIVES: Liver replacement continues to be the only definitive mode of therapy for children with end-stage liver disease. However, it remains challenging because of the rare donor organs, complex surgical demands, and the necessity to prevent long-term complications. Our objectives were to analyze 16 years of experience in the Shiraz University Organ Transplant Center. MATERIALS AND METHODS: We retrospectively analyzed the records of 752 patients (< 18 years old) who underwent orthotopic liver transplant at our center over a 16-year period...

En bloc kidney transplants of small pediatric kidneys into adult recipients have been shown to have outcomes similar to transplants from standard adult deceased donors. Here, we report a 27-year-old male patient with successful repair of bilateral ureteral stricture 3 years after en bloc kidney transplant at the Shahid Modarres Hospital (Tehran, Iran). The patient received an en bloc deceased kidney donation from a 9-month-old infant. An end-to-end anastomosis of the aorta to the internal iliac artery and an end-to-side external iliac vein anastomosis to vena cava were performed...
