BACKGROUND Machine cold perfusion is beneficial to the preservation of kidneys for transplantation. At the end of preservation, the perfusion solution contains many proteins. Using a proteomics approach, we searched for useful biomarkers and potential therapeutic targets in the perfusate. Our program is unique in that all transplant kidneys (even living donor kidneys, LKD) are placed on machine cold perfusion prior to transplantation. MATERIAL AND METHODS Perfusates from donation after neurological and circulatory determination of death (DNDD and DCDD respectively) and LKD were collected (n=41) and analyzed for LDH, neutrophil gelatinase-associated lipocalin (NGAL), and matrix metalloproteinase-2 (MMP-2) as markers of injury...

BACKGROUND Standard methods for endoscopic retrograde cholangiopancreatography (ERCP) management of anastomotic strictures (AS) after OLT includes repeated balloon dilation of the stricture with subsequent insertion of a plastic biliary stent (PBS). In post-OLT patients not responding to standard endoscopic treatment, the placement of fully covered self-expanding metal stents (FCSEMS) is a valid alternative to surgical treatment. The aim of this study was to compare the results of new FCSEMS implantation with the standard ERCP stricture management protocol and with conventional FCSEMS insertion...

BACKGROUND This study was designed to analyze the clinical implications of mycophenolic acid trough concentration monitoring. MATERIAL AND METHODS We collected data of patients with mycophenolic acid trough concentration monitoring after their first kidney transplant between November 2006 and March 2015 who were prescribed tacrolimus, mycophenolate, and methylprednisolone. Analyses were performed on 3 periods: 1 month, 1 month to 1 year, and after 1 year post-transplantation. To analyze factors related to acute cellular rejection, logistic regression was used for 1 month, while Cox analysis was used during 1 month to 1 year and after 1 year post-transplantation...

BACKGROUND In patients with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) co-infection, HIV can modulate HCV replication and immune response as well as accelerate liver fibrosis. The role of miRNA in HIV/HCV co-infection is not fully elucidated. The aim of this study was to examine the differential expression of miRNAs in the liver. MATERIAL AND METHODS Thirteen patients who had undergone a liver transplant (7 HCV-infected and 6 HIV/HCV-co-infected patients) were examined using a miRNA array containing 1347 human miRNAs...

BACKGROUND The incidence of incisional hernia following renal transplantation is 1.1% to 3.8%. The risk factors are immunosuppressive medications, impaired tissue quality, neuromuscular trauma due to the operation, and denervation. The incidence has been decreasing based on the shift from hockey-stick incision method to inguinal oblique incision method. The aim of this study was to minimize the development of incisional hernias due to renal transplantation. MATERIAL AND METHODS Twenty-four patients who underwent renal transplantation in 2015-2017 were retrospectively examined...

BACKGROUND The aim of this study was to find the main risk factors for development of cardiac allograft vasculopathy (CAV), especially factors identified before the surgical procedure and factors related to the recipient profile and the medical history of the donor. MATERIAL AND METHODS There were 147 patients who had heart transplantation (HT) included in this study: mean age was 45.8±15.3 years. All study patients had coronary angiography after HT. Analyzed risk factors were: non-immunologic recipient risk factors (age of transplantation, smoking, hypertension, lipids, diabetes, obesity and weight gain after HT), immunologic recipient risk factors (acute cellular rejection (ACR), acute humoral rejection (AMR), cytomegalovirus (CMV) episodes), and donor-related risk factors (age, sex, catecholamine usage, ischemic time, compatibility of sex and blood groups, cause of death, cardiac arrest)...

BACKGROUND Lung transplant (LTx) recipients suffer from high rates of malignancy. Exposure to immunosuppressive medication such as tacrolimus has been proposed as a risk factor for tumorigenesis. We hypothesized that chronically high levels of tacrolimus would be associated with risk of malignancy. MATERIAL AND METHODS The study was performed in a transplant center in Israel, with a nested case-control design. Cases were LTx recipients who were diagnosed with any solid or hematological malignancy except non-melanoma skin cancer...

BACKGROUND Biliary complications (BCs) following liver transplantation are very serious. Nevertheless, it is still uncertain which components influence the incidence of BCs the most. MATERIAL AND METHODS A consecutive sample of 74 adult recipients who underwent living-donor liver transplantation were enrolled in this study. BCs that were Clavien-Dindo classification grade II or higher were determined as BCs. RESULTS There were 11 out of the 74 recipients who experienced BCs. There were no differences in preoperative background factors between the BCs+ and BCs- group...

The Kidney Donor Risk Index (KDRI) and Kidney Donor Profile Index (KDPI) assist clinicians with the selection of deceased donor kidneys. This scoring system is based on 10 donor factors including Hepatitis C virus (HCV) status from serological or NAT testing. The donor HCV status (i.e., having either a positive hepatitis C antibody (Ab) or nucleic acid testing (NAT) result) increases the hazard ratio for graft failure by 1.27 and the KDPI by approximately 20%. Whether this increase in KDPI is a true reflection of graft quality for HCV seropositive but not viremic donors is unknown...

BACKGROUND STAT1/4 has been suggested to be involved in cardiac allograft rejection. However, no direct evidence regarding STAT3 has been established in cardiac allograft rejection. Here, we hypothesized that inhibition of STAT3 attenuates cardiac allograft rejection. MATERIAL AND METHODS To test our hypothesis, homotopic mouse heart transplantation was carried out in syngeneic C57BL/6 to C57BL/6 strain mice with or without oral gavage with NSC 74859, an inhibitor of STAT3. The immune response was investigated using real-time PCR for CD4 and CD8 surface makers of T cells and CD14 of monocytes and cytokines, including IL-2, IL-15, and IL-6 of allografts at 3, 6, and 9 days after transplantation...

BACKGROUND Genetic alterations of TGF-β pathway members, including its transmembrane receptor, TGFBR1, may influence the course of HCV infection. Rs868 is a single-nucleotide polymorphism of the 3'UTR region of TGFBR1, located in a binding site for the conserved let-7/miR98 microRNA family. Previously, we demonstrated a favorable course of hepatitis C recurrence after liver transplantation in rs868 AG genotype of the transplanted liver when compared to rs868 AA. The aim of the present study was to confirm the biological effect of rs868...

BACKGROUND Liver transplantation (LT) in infants is a challenging procedure. This study was designed to identify risk factors of 30-day mortality of infant LT recipients. MATERIAL AND METHODS A total of 101 infants treated between May 1997 and March 2015 were assigned to one of two groups, a deceased infant group (n=9) or a live infant group (n=92), according to their mortality status at 30 days after LT. RESULTS Patient characteristics of height, weight, preoperative total bilirubin, creatinine clearance, primary diagnosis, and graft-to-recipient weight ratio (GRWR) were significantly different between the two groups...

BACKGROUND This is the largest UK-based study on the effect of recipient body mass index (BMI) and its extremes (BMI <18.5 and BMI ≥35 kg/m²) on liver transplant (LT) outcomes. Its purpose was to analyze the BMI effect on post-LT mortality, graft loss, primary non-function (PNF), and graft vascular and biliary complications. MATERIAL AND METHODS Data were retrieved from a single-center LT database of 2,115 consecutive patients receiving first LT during period February 2004 to September 2015. Survivals were compared across the BMI groups; the effects of recipient BMI on survival, PNF, and graft vascular and biliary complications were analyzed via regression...

BACKGROUND Liver transplantation (LT) is the best radical treatment of hepatocellular carcinoma (HCC). Salvage liver transplantation (SalvLT) provides good outcomes for recurrent HCC cases after initial curative liver resection (LR). However, the salvage strategy is not feasible in all situations due to aggressive recurrences. Recently, sequential liver transplantation (SeqLT) was proposed for cases that show adverse pathological features after LR, thus LT is performed pre-emptively before recurrence. In this report, we compared the outcomes of SalvLT and SeqLT for surgical treatment of HCC...

The region of Sicily, Italy, is witnessing a chronic organ shortage. Thus, to face this critical issue, the use of marginal donors has increased over time. An example of marginal donor expansion is the use of liver donors who are positive for the hepatitis C antibody (HCV+) for HCV+ patients requiring liver transplantation (LT). In view of new advances in HCV therapy, including direct-acting agents (DAAs) to treat HCV in the post-transplant setting, our study focused on a monocentric experience in a series of consecutive LTs performed in adult patients receiving HCV+ liver donor allografts...
