OBJECTIVES: Elevated plasma fibrinogen (Fib) correlated with patient's prognosis in several solid tumors. However, few studies have illuminated the relationship between preoperative Fib and prognosis of HCC after liver transplantation. We aimed to clarify the prognostic value of Fib and whether the prognostic accuracy can be enhanced by the combination of Fib and neutrophil-lymphocyte ratio (NLR). RESULTS: Fib was correlated with Child-pugh stage, alpha-fetoprotein (AFP), size of largest tumor, macro- and micro-vascular invasion...

BACKGROUND: Infections, particularly urinary tract infections, and cardiovascular accidents are the main causes of morbidity and mortality during the 1st year after kidney transplantation (KT). Bacteria and viruses, such as Escherichia coli, Enteroccoci, and Polyoma BK virus are common in the 1st 6 months, so they are controlled routinely. On the other hand, Clostridium perfringens infection is a rare life-threatening condition, associated with a high mortality rate especially in the transplant population, that is not controlled routinely...

INTRODUCTION: Elective heart transplantation (HTX) aims to improve physical ability, increase survival, and improve health-related quality of life (HRQoL) in patients with chronic heart failure. Nevertheless, most patients who undergo urgent HTX are previously healthy, and a transplant could be perceived as a limitation. The aim of this study is to compare HRQoL between elective and urgent heart transplant recipients. METHODS: Cohort study including patients undergoing heart transplantation between January 1998 and March 2012 in a single center...

OBJECTIVES: The authors sought to identify strictures or hepatic artery obstruction with posterior collateral transformation in our series of liver transplantation, treatment, and evolution. The thrombosis or severe hepatic artery stenosis sometimes presents a compensation mechanism, the collateral transformation of the artery. MATERIAL AND METHODS: From April 2002 to December 2011 we collected 18 cases of collateral transformation. We analyzed data regarding the transplantation, diagnosis, treatment, clinical evolution, liver function, and Doppler-ultrasound...

BACKGROUND: Hepatitis C is a common indication for liver transplantation (LT). Hepatitis C virus (HCV) recurrence is universal in viremic patients. This recurrence is frequently very aggressive, with graft loss in less than 5 years. Our aim is to detect which factors are related to worse fibrosis at 1 year post-LT. PATIENTS AND METHODS: Records of all HCV-positive transplanted patients in Hospital Universitario Nuestra Señora de la Candelaria from 1996 to 2014 were collected...

INTRODUCTION: Accumulating evidence indicates that interleukin (IL)-34 participates in T-cell homeostasis and tolerance due to the ability of IL-34 to trigger apoptosis of Th1, Th17, and Tc1 cells, but spare Th2 cells and Treg. In addition, IL-34 exerts anti-inflammatory effects by impairing leukocyte adhesion and transendothelial migration, and reducing the secretion of proinflammatory cytokines. The aim of our study was to investigate the time course of serum levels of IL-34 during hepatic allograft rejection...

BACKGROUND: Malignancy is one of the most common long-term complications in renal transplant patients, often related to immunosuppressive treatment although other factors could be considered. Vitamin D plays an important role in reducing cancer risk. After kidney transplantation (KT), 25-hydroxyvitamin D (25OH-D, or calcidiol) insufficiency concerns >85%. The main aim of the present study was to determine the relationship between calcidiol blood levels and cancer development in KT recipients...

En bloc pediatric transplantation (EBPT) began with the aim of increasing the donor pool due to the existing high demand for donors. At its inception, it was considered a type of suboptimal transplantation due to its association with a high incidence of vascular, urologic, and immunologic complications. The main objective of this study was to update information on EBPT with the largest case series that exists on a worldwide scale. In a retrospective study, the results obtained from brain-dead donors (BDDs; n = 770) were compared to those of EBPT (n = 100) from January 1990 to December 2012...

BACKGROUND: Infection of the urinary tract (UTI) is the most common form of bacterial infection in renal transplant patients, but its management is still controversial. We compared symptomatic and asymptomatic bacteriuria, treated or untreated, during two different months (summer or winter). METHODS: This longitudinal, prospective study involved routine urine cultures collected during September 2014 or March 2015. Demographic, clinical, and microbiological characteristics from the patients with positive urine cultures were described...

Access to kidney transplantation for patients with high levels of antibodies against HLA is a major challenge. This issue makes it difficult to detect compatible donors for those patients in a certain geographical area. Consequently, hypersensitized patients remain on the waiting list for long periods and their quality of life deteriorates. Our purpose was to increase access to transplantation for highly sensitized patients by developing a national priority allocation system based on virtual crossmatch. Between June 15, 2015, and May 15, 2016, 675 patients on the kidney transplant waiting list with calculated panel-reactive antibodies ≥98% and undergoing dialysis for at least 12 months were included in the study; 86...

BACKGROUND: Immunosuppression (IS) protocols should be individualized according to the individual recipient's immunity to minimize adverse effects. The aim of this study was to determine whether preoperative levels of CD8+ T lymphocytes could be used as a guide for the introduction of IS. METHODS: Sixteen adult liver transplantations in our institute were retrospectively analyzed. The immunosuppressive agents were temporarily withheld for 8 patients with a lower (<10%) preoperative percentage of CD8+ cells after transplant (classified as group A)...

The aim of the current study was to characterize the anti-HLA antibodies before and after pancreatic islet or pancreas transplantation. We assessed the risk of anti-donor-specific antibody (DSA) sensitization in a single-center, retrospective clinical study at Geneva University Hospital. Data regarding clinical characteristics, graft outcome, HLA mismatch, donor HLA immunogenicity, and anti-HLA antibody characteristics were collected. Between January 2008 and July 2014, 18 patients received islet transplants, and 26 patients received a pancreas transplant...

Xenotransplantation has vast clinical potential but is limited by the potent immune responses generated against xenogeneic tissue. Immune-privileged Sertoli cells (SCs) survive xenotransplantation long term (90 days) without immunosuppression, making SCs an ideal model to identify xenograft survival mechanisms. Xenograft rejection includes the binding of natural and induced antibodies and the activation of the complement cascade. Using an in vitro cytotoxicity assay, wherein cells were cultured with human serum and complement, we demonstrated that neonatal pig SCs (NPSCs) are resistant to complement-mediated cell lysis and express complement inhibitory factors, membrane cofactor protein (MCP; CD46), and decay-accelerating factor (DAF; CD55) at significantly higher levels than neonatal pig islets (NPIs), which served as non-immune-privileged controls...

Significant racial disparity remains in the incidence of unfavorable outcomes following heart transplantation. We sought to determine which pediatric post-transplantation outcomes differ by race and whether these can be explained by recipient demographic, clinical, and genetic attributes. Data were collected for 80 black and 450 non-black pediatric recipients transplanted at 1 of 6 centers between 1993 and 2008. Genotyping was performed for 20 candidate genes. Average follow-up was 6.25 years. Unadjusted five-year rates for death (p=0...

CCR2 is a chemokine receptor expressed on the surface of blood leukocytes, particularly «Ly6Chi» inflammatory monocytes and microglia. Signaling through this receptor is thought to influence the immune activity of microglia as well as monocytes egress from the bone marrow (BM) and their trafficking into the central nervous system (CNS) in several neurological diseases. During experimental herpes simplex virus 1 (HSV-1) encephalitis (HSE), CCR2 deficiency has been reported to exacerbate the outcome of the disease...

Galactose-deficient IgA1 (Gd-IgA1) and IgA-IgG complexes are known to play an important role in the pathogenesis of IgA nephropathy (IgAN). We aimed therefore to determine the impact of immunosuppression on the serum levels of Gd-IgA1, total IgA1 and IgA-IgG complexes in IgAN patients. In a retrospective study, serum samples from IgAN patients collected before transplantation (t0) and at 3- and 6-month posttransplant (t3 & t6) were used to measure the levels of Gd-IgA1, total IgA1 and IgA-IgG complexes. The area under the curves (AUC) of immunosuppressants was calculated by the plot of plasma trough level or dosage of each immunosuppressant versus time and was interpreted as the extent of drug exposure...

BACKGROUND: Caregiving for allogeneic hematopoietic stem cell transplant (Allo-HSCT) patients can be significantly burdensome. Caregiver well-being often mirrors patients' suffering. However, to our knowledge, this dyadic relationship has not been linked to patient outcome. OBJECTIVE: Caregiver's objective and subjective sleep and overall distress before transplantation were hypothesized to be related to patient's time to engraftment in secondary analyses. METHODS: Dyads (N = 124) were Allo-HSCT patients (mean [SD] age, 49...

Haematopoietic stem cell transplantation-coordinating nurses (HSCT-CNs) play an important role in informing related donors (RDs) and in organising human leucocyte antigen (HLA) tests, pre-donation workup and stem cells collection. Our pilot study aimed to explore French HSCT-CNs' perceptions of RD care issues. Twenty-nine French HSCT adult units were sent a questionnaire on the subject of donation procedures, HSCT-CNs' data and their professional experience of related donation issues. Twenty-two HSCT-CNs returned a completed questionnaire, and 90% of HSCT units were involved to some degree in both patient and donor care...
