BACKGROUND Inducing transplantation tolerance and monitoring the recipient's immune status to improve allograft survival remains the main goal for kidney transplantation (KTx). MATERIAL AND METHODS A total of 53 renal transplantation patients and 20 healthy individuals were assigned to the post-transplantation and healthy groups, respectively; 10 recipients with stable renal function for 2 years after kidney transplantation were assigned to Group C. Eleven kidney transplantation recipients were hospitalized due to lung infection...

BACKGROUND In liver transplantation (LT), preoperative desensitization therapy is considered necessary in patients positive for donor-specific anti-human leukocyte antigen antibodies (DSAs). However, the relationship between DSA intensity and the necessary desensitization therapy is unclear. MATERIAL AND METHODS A total of 37 adult living donor (LD) LTs performed between January 2016 and March 2022 were examined. Mycophenolate mofetil (MMF) was administered preoperatively in DSA-positive cases with positive lymphocyte cross-matching who underwent LDLT...

A number types of extracellular DNA (eg, cell-free, cfDNA) circulate in human blood, including mitochondrial, transcriptome, and regulatory DNA, usually at low concentrations. Larger amounts of cfDNA appear in any inflammatory condition, including organ damage due to a variety of reasons. The role of cfDNA in solid organ transplantation is discussed in this review as a valuable additional tool in the standard of care of transplant patients. Post-transplant monitoring requires the use of high-quality biomarkers for early detection of graft damage or rejection to be able to apply early therapeutic intervention...

BACKGROUND EPTS (Estimated Post-Transplant Survival), KDRI (Kidney Donor Risk Index), and KDPI (Kidney Donor Profile Index) were developed aiming to ameliorate donor-recipient longevity matching in kidney transplants. They are based on a prediction model made using the United States population; evidence of their use outside EEUU remains limited. The aim of this study was to describe the quality of deceased-donor kidneys and to determine recipient and graft survival, glomerular filtration rate, and incidence of delayed graft function in renal transplantation according to these indices in Cali, Colombia...

BACKGROUND Membranoproliferative glomerulonephritis (MPGN) is an uncommon cause of end-stage renal disease (ESRD). Recurrence rates after transplantation range from 11.8% to 18.9% after 5 and 15 years, respectively. This study aimed to assess the risk factors of MPGN recurrence after kidney transplantation and its impact on graft survival. MATERIAL AND METHODS This was a single-center retrospective cohort, including renal transplant recipients older than 18 years, with a diagnosis of MPGN in native kidneys...

BACKGROUND The present study evaluated expanded cause of death (COD) definitions and its implications on donor utilization for solid organ transplantation. MATERIAL AND METHODS The OPTN Standard Transplant and Research file was queried for potential donors between 2005 and 2019. Donor- and organ-specific utilization were evaluated. Expanded donor COD were identified: trauma, cardiovascular (CV), cerebrovascular accident (CVA) or stroke, drug intoxication (DI), anoxia not otherwise specified (NOS), and other...

BACKGROUND Recently, there has been a recommendation to utilize a combination of supportive extracorporeal therapies, specifically plasma exchange and continuous venovenous hemodiafiltration, in patients with acute liver failure. This 15-year retrospective study aimed to evaluate supportive extracorporeal therapy, including plasma exchange and continuous venovenous hemodiafiltration, for 114 adults with acute liver failure awaiting liver transplant. MATERIAL AND METHODS In this retrospective study, the medical records of 1288 adult patients who underwent liver transplantation and 161 adult patients who received alternative therapy were analyzed; 114 patients who received combined supportive extracorporeal therapy for acute liver failure were included in the study...

BACKGROUND Transplant-associated thrombotic microangiopathy (TA-TMA) is a serious complication of hematopoietic stem cell transplantation (HSCT). The efficacy and survival of plasma exchange (PE) for TA-TM have not been fully clarified. In addition, there is a lack of consensus on diagnostic criteria for TA-TMA.  MATERIAL AND METHODS We retrospectively analyzed 32 patients diagnosed with TA-TMA by different diagnostic criteria from January 2018 to February 2022 at the First Medical Center of the PLA General Hospital...

BACKGROUND Aspirin prophylaxis has been associated with reduced graft-related thrombosis following kidney transplantation. Aspirin cessation, however, can increase risk of venous thromboembolic complications, including pulmonary thromboembolism and deep venous thrombosis. This single-center, retrospective, pre-post interventional study from Brisbane, Australia, aimed to compare the rate of thrombotic complications in 1208 adult kidney transplant recipients receiving postoperative aspirin for 5 days or >6 weeks...

BACKGROUND Liver retransplantation (reLT) is a well-accepted treatment for liver graft failure in selected patients. A rescue hepatectomy (RH), on the contrary, is a rare and controversial procedure in which a deteriorating liver graft causing failure of other organ systems is removed to stabilize the patient's condition before a new liver graft is available. MATERIAL AND METHODS In this retrospective cohort study, we evaluated the outcomes of the 104 patients who were listed for a first single-organ reLT in our center during the period 2000-2019, to compare the results after RH to other reLTs...

BACKGROUND Maple syrup urine disease (MSUD) is a rare genetic deficiency of the branched-chain alpha-keto acid dehydrogenase (BCKAD) complex that breaks down amino acids, resulting in multi-organ failure. This report is of 5 pediatric cases of domino liver transplantation (DLT) from live donors with MSUD from a single transplant center in Beijing. CASE REPORT All MSUD donors were confirmed to have disease-causing mutations in BCKDHA (branched-chain keto acid dehydrogenase E1, alpha polypeptide) or BCKDHB (branched-chain keto acid dehydrogenase E1, ß polypeptide) genes by peripheral blood whole-exon sequencing...

BACKGROUND Simultaneous pancreas-kidney transplantation (SPK) is a time-consuming and important surgical procedure, which can provide a physiological mean of achieving normoglycemia and render patients free of dialysis. The potential clinical benefits of sugammadex include fast and predictable reverse deep neuromuscular blockade (NMB), but whether sugammadex affects the function of SPK grafts is uncertain. MATERIAL AND METHODS Forty-eight patients were studied and reversed deep NMB with either sugammadex (n=24) or neostigmine (n=24)...

BACKGROUND Carbapenems are the primary treatment for urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae. However, the recurrence rate is high, and patients often require rehospitalization. We present the results of an observational study on patients with recurrent UTIs who were treated in an outpatient setting with maximal therapeutic oral doses of amoxicillin with clavulanic acid. MATERIAL AND METHODS All patients had pyuria and ESBL-producing K...

BACKGROUND Access to kidney transplantation is limited for elderly patients with end-stage renal disease (ESRD), who often die while on the waiting list or receive kidneys from marginal deceased donors. In our transplantation center, most donated kidneys were from younger living relatives, in whom donations to elderly outcomes were not previously studied. In this study, we aimed to determine the short- and long-term outcomes of patients aged ³65 years to justify the use of kidneys from younger donors in older recipients...

BACKGROUND This study aimed to compare the incidence of brain-dead (BD) donors and potential brain-dead (PBD) donors before vs after the introduction of intensivists. MATERIAL AND METHODS This longitudinal retrospective study was performed between January 2012 and December 2020 at Seoul Metropolitan Government-Seoul National University Boramae Medical Center. Four dedicated intensivists were introduced in January 2016. The periods before and after introduction of the intensivists were defined as the pre-introduction period (2012-2015) and post-introduction period (2016-2020), respectively...

BACKGROUND Sodium bicarbonate Ringer's solution (BRS) is the latest generation of balanced crystal solutions. BRS does not increase the liver burden, but its impact in liver transplantation is unclear. The aim of this study was to investigate the effect of BRS as a fluid therapy on intraoperative blood gas analysis and postoperative recovery time in orthotopic liver transplantation (LT) patients. MATERIAL AND METHODS The study included 101 patients who received classical in situ liver transplantation at the Second Affiliated Hospital of Guangxi Medical University from November 2019 to January 2022...

BACKGROUND Cardiovascular (CV) mortality remains high despite the improvement of kidney function after kidney transplantation. In heart failure (HF), high concentrations of biomarkers of fibrosis, related to cardiac and/or vascular impairment, are associated with CV outcomes, but their significance in kidney transplantation is still unclear. Our aim was to investigate the association of procollagen type I C-terminal pro-peptide (PICP) and galectin-3 (Gal-3), markers of fibrosis, with arterial stiffness measured by pulse wave velocity (PWV) and CV morbi-mortality in kidney transplantation recipients from the prospective monocenter TRANSARTE study (Transplantation and Arteries), which compared the evolution of arterial stiffness in transplanted patients and patients remained on dialysis...

BACKGROUND Taiwan has a high prevalence of hepatitis B virus (HBV) infection. HBV-related end-stage liver disease is the leading cause of liver transplantation (LT). Tenofovir alafenamide (TAF) is a recently approved agent for the treatment of chronic HBV infection that improves renal profiles compared with tenofovir disoproxil fumarate (TDF) in phase III trials. This study aimed to assess the outcomes of TAF treatment in LT recipients. MATERIAL AND METHODS This retrospective study analyzed 17 LT recipients who underwent treatment with TDF and TAF...

BACKGROUND Because of the massive organ shortage worldwide, marginal organs are increasingly being considered. The aim of this study was to present a comprehensive analysis of donor-related factors clinically supposed to influence the outcome after liver transplantation. This study from a single center in Germany aimed to evaluate postoperative outcomes in 415 patients following liver transplantation using extended donor criteria. MATERIAL AND METHODS Extended donor criteria (EDC) were considered according to the official guidelines issued through the German Medical Association...
