Tacrolimus-associated thrombotic microangiopathy (TA-TMA) is a rare complication. TA-TMA is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ damage due to thrombus. We report asymptomatic TA-TMA diagnosed by laboratory tests in pig-to-rhesus corneal xenotransplantation. Corneal transplantation had been conducted from a wild-type SNU miniature pig to a rhesus macaque. The veterinary records were retrospectively reviewed in this case. The immunosuppressive regimen consisted of rituximab, basiliximab, and IVIg as inductive therapies, and steroids with tacrolimus (0...

Ischemia/reperfusion (I/R) injury is a causative factor contributing to morbidity and mortality during liver resection and transplantation. Livers from elderly patients have a poorer recovery from these surgeries, indicating reduced reparative capacity with aging. Mechanisms underlying this age-mediated hypersensitivity to I/R injury remain poorly understood. Here, we investigated how sirtuin 1 (SIRT1) and mitofusin 2 (MFN2) are affected by I/R in aged livers. Young (3 months) and old (23-26 months) male C57/BL6 mice were subjected to hepatic I/R in vivo...

Drug-induced liver injury (DILI) is a leading cause of acute liver failure and transplantation. DILI can be the result of impaired hepatobiliary transporters, with altered bile formation, flow, and subsequent cholestasis. We used gadoxetate dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), combined with pharmacokinetic modelling, to measure hepatobiliary transporter function in vivo in rats. The sensitivity and robustness of the method was tested by evaluating the effect of a clinical dose of the antibiotic rifampicin in four different preclinical imaging centers...

Primary biliary cholangitis (PBC) is a rare chronic cholestatic liver disease that may progress to biliary cirrhosis if left untreated. The first-line therapy for PBC is ursodeoxycholic acid (UDCA). Unfortunately, 1 of 3 patients does not respond to UDCA. These patients are at risk for developing clinical events, including cirrhosis, complications of portal hypertension, hepatocellular carcinoma, liver transplant, or death. Recently, the U.S. Food and Drug Administration approved obeticholic acid to be used in certain patients with PBC...

Transplantation-associated thrombotic microangiopathy (TA-TMA) is a serious complication of hematopoietic stem cell transplantation (HSCT). We characterized the incidence, risk factors, and long-term outcomes associated with TA-TMA by performing a comprehensive review of all adult patients (n=1,990) undergoing allogeneic HSCT at the Dana Farber Cancer Institute/Brigham and Women's Hospital between 2005 and 2013. Using the City of Hope criteria, we identified 258 (13%) and 508 (26%) patients with "definite" and "probable" TMA, respectively...

Transportable normothermic kidney perfusion for 24 hours or longer could enable viability assessment of marginal grafts, increased organ utilization and improved transplantation logistics. Eleven clinically-declined kidneys were perfused normothermically, six from donors after brain stem death (DBD, median cold ischemia time 33±36.9 hours) and five from donors after circulatory death (DCD, 36.2±38.3 hours): n=3 kidneys were perfused using Ringer's lactate to replace excreted urine volume, and n=8 using urine recirculation to maintain perfusate volume without fluid replenishment...

NKG2D is an important immunoreceptor expressed on the surface of NK cells and some T cells. NKG2D recognizes a set of ligands typically expressed on infected or transformed cells, but recent studies have also documented NKG2D ligands on subsets of host non-tumor cells in tumor-bearing animals and humans. Here we show that in transplanted tumors and genetically engineered mouse cancer models, tumor-associated macrophages are induced to express the NKG2D ligand RAE-1δ. We find that a soluble factor produced by tumor cells is responsible for macrophage RAE-1δ induction, and we identify tumor-derived colony-stimulating factor-1 (CSF-1) as necessary and sufficient for macrophage RAE-1δ induction in vitro and in vivo ...

We developed a highly elastic customized scaffold for soft-tissue regeneration and combined them with bioactive hydrogels with stem-cell-inducing ability. This was done to mimic mechanical properties of native soft tissues and improve the viability of transplanted cells as well as efficiency of tissue regeneration. The proposed study was aimed at evaluating various characteristics of scaffolds and investigating their tissue regenerating ability. Finger shaped porous scaffolds were successfully fabricated by an indirect 3D printing of poly (L-lactide-co-ε-caprolactone) (PLCL) which provides a high elasticity for soft tissue engineering...

Split liver transplantation (SLT) should be cautiously considered because the right tri-sectional (RTS) graft can be a marginal graft in adult recipients. Herein, we analyzed the outcomes of RTS-SLT in Korea, where > 75% of adult liver transplantations are performed by living donor liver transplantation. Among 2,462 patients who underwent deceased donor liver transplantations (DDLT) from 2005 to 2014, we retrospectively reviewed 86 adult patients (3.4%) who received a RTS graft (RTS-SLT group). The outcomes of the RTS-SLT group were compared to those of 303 recipients of whole liver (WL-DDLT group)...

To evaluate the association between sarcopenia and tumor recurrence after living donor liver transplantation (LDLT) in patients with advanced hepatocellular carcinoma (HCC), we analyzed 92 males who underwent LDLT for treating HCC beyond the Milan criteria. Sarcopenia was defined when the height-normalized psoas muscle thickness was <15.5 mm/m at the L3 vertebra level on computed tomography based on an optimum stratification method using the Gray's test statistic. Survival analysis was performed with death as a competing risk event...

Optimal donor selection is critical for successful allogeneic hematopoietic cell transplantation (HCT). Donor sex and parity are well-established risk factors for graft-versus-host disease (GVHD), with male donors typically associated with lower rates of GVHD. Well-matched unrelated donors (URDs) have also been associated with increased risks of GVHD as compared with matched sibling donors. These observations raise the question of whether male URDs would lead to more (or less) favorable transplant outcomes as compared with parous female sibling donors...

Many of the testicular cancer-survived patients, treated with chemotherapeutic drugs, show infertility, preimplantation and postimplantation loss, and germ cell abnormality. Studies examining the negative effects of chemotherapeutic drugs on testicular germ cells are ongoing; however, information on the stemness properties and proteomic profiles of these cells are lacking. The present study investigated the effects of chemotherapeutic drugs etoposide, cisplatin, bleomycin, and their combination (BEP) on the physiology and stem cell activity of mouse germ cells in vitro...

The detailed kinetics of the cytomegalovirus (CMV)-specific T cell response in hematopoietic stem cell transplant (HCT) recipients have not yet been fully assessed. We evaluated these kinetics of CMV-specific T cell response and factors associated with high CMV-specific T cell responses 1 year after HCT. In HCT recipients, CMV pp65 and IE1-specific ELISPOT assay were performed before HCT (D0), and at 30 (D30), 90 (D90), 180 (D180), and 360 (D360) days after HCT. Of the 51 HCT recipients with donor-positive (D+ )/recipient-positive (R+ ) serology, 26 (51%) developed CMV infections after HCT...

BACKGROUND: Rejection and infection can occur after kidney transplantation and are important factors in preserving graft kidney function. The use of immunosuppressant agents in transplantation is therefore important, and the question of which induction therapy should be used as an immunosuppressant is controversial. OBJECTIVE: The goal of this study was to assess the comparative benefits and harms of various maintenance immunosuppressive induction agents in adults undergoing kidney transplantation by using a network meta-analysis and to generate rankings of the different immunosuppressive regimens according to their safety and efficacy...
