Acute kidney injury (AKI) is a major complication in orthotopic liver transplantation (OLT). In an evaluation of Acute Kidney Injury Network (AKIN) criteria in liver transplanted patients, we retrospectively analyzed the usefulness of these criteria to predict survival of 193 consecutive patients at a single center who underwent primary OLT for clinical parameters and peak AKI. Postoperative AKI according to AKIN occurred in 60.1% of the patients, namely, stages 1, 2, and 3 in 30%, 13% and 17.1% respectively. ⋯ Cox regression analysis showed independent risk factors for mortality during the first year after transplantation to include post-OLT AKI (12.1; P < .05), post-OLT infection (HR 4.7; P < .01), pre-OLT hypertension (HR 4.4; P < .01) hazard ratio [HR] and post-OLT APACHE II ≥10 (HR 3.6; P < .05). We concluded that AKI as defined by the AKIN criteria is a major complication of OLT linked to a poor outcomes. It remains to be evaluated whether aggressive perioperative therapy to prevent AKI can improve survival among OLT patients.

The aim of this study was to investigate the prevalence of hyperuricemia and factors predicting its occurrence, and to establish the relationship over time between serial changes in estimated glomerular filtration rate (eGFR) and uric acid (UR) concentration in kidney transplant (KT) recipients with eGFR >60 mL/min/1.73 m(2). ⋯ Transplantation duration, male gender, eGFR level, DM, and serum calcium level were risk factors for hyperuricemia in kidney recipients with intact graft function. Increased uric acid after KT did not significantly affect graft function.

This study was performed to determine the feasibility of second hematopoietic stem cell transplantation (HSCT) using reduced-intensity conditioning (RIC) with fludarabine and melphalan in patients with relapsed hematologic malignancies after a prior autologous HSCT. Twelve patients (multiple myeloma [n = 7], non-Hodgkin lymphoma [n = 3], and acute myeloid leukemia [n = 2] received allogeneic HSCT using RIC with fludarabine (25 mg/m(2) for 5 days) and melphalan (140 mg/m(2) for 1 day) after a failed autologous HSCT. The graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine plus a minidose of methotrexate. ⋯ The estimated nonrelapse mortality at 1 year was 28.4%. The estimated overall survival rate at 1 year was 58.3%, and the estimated event-free survival rate at 1 year was 41.7%. Allogeneic HSCT using RIC with fludarabine and melphalan appears to be feasible for a second HSCT in patients with relapsed hematologic malignancies after a failed autologous HSCT.

Educating physicians about transplantation during undergraduate training can improve organ procurement rates. The aim of this study was to evaluate and analyze the knowledge of medical students regarding transplantation. ⋯ Medical students have limited knowledge about organ transplantation; there is a need for educational intervention early in the medical curriculum.

Tubular enzymes (TE) are early markers of acute kidney injury (AKI), but their value for liver transplant (LT) recipients is unknown. We sought to evaluate the usefulness of TE to predict AKI after LT. We enrolled Thirty-nine adult patients without AKI who had been admitted to the Intensive Care Unit (ICU). ⋯ In the LT group, on the first day of the patients' stay in the ICU, urinary LDH (P = .032), AF (P = .022), and γ-GT (P = .002) were significantly higher among those who developed AKI; these elevations preceded those of serum creatinine. In forward receiver-operating characteristic (ROC) plot analysis, the areas under the ROC curves were 0.8, 0.86, and 0.92 for LDH, AF, and γ-GT, respectively. We concluded that TE determined early after LT are a helpful predictors of AKI.
