    Polymorphic PTLD was eventually diagnosed. No recurrence or new set lesions were detected after 6-month follow-up.

    This is the first case describing PTLD may originate from reconstructed MHV after pediatric living donor liver transplant. As a life-threatening complication of liver transplant, surgical resection should be considered as a safe and feasible treatment for the single resectable mass.

    Acute kidney injury (AKI) is common after liver transplantation and affects outcome after liver transplantation. click here Antibody induction is commonly used to reduce dose and/or to delay introduction of calcineurin inhibitor (CNI) but is very expensive. We propose a modified immunosuppressive protocol that delays administration of CNI for 48 to 72 hours without antibody induction. This study evaluates the results of our new protocol.

    A retrospective case-control study was performed. Study patients had induction with steroid and mycophenolate mofetil without antibody induction, and CNI administration was delayed for 48 to 72 hours. Control patients received CNI and steroid induction without antibody induction, and CNI was continued posttransplant. AKI was defined as an increase in serum creatinine level of at least 1.5 times the pretransplant baseline within the first postoperative week.

    Sixty liver transplant recipients from 2013 to 2015 were included in this study (30 in the delayed CNI group and 30 in the control group). The patient characteristics and intraoperative factors were comparable in both groups. AKI developed in 11 patients in the study group and in 20 patients in the control group (37% vs 66.7%; P= .02). There was no acute rejection observed in the first month in either group.

    We have demonstrated that delayed CNI introduction without antibody induction is safe and helps preserve kidney function. Antibody induction can be omitted safely in a delayed CNI introduction protocol to reduce the cost of liver transplantation without increasing the risk of acute rejection.

    Hyperkalemia (HK) is a life-threatening complication following solid organ transplantation, and patients often need potassium-chelating agents and deviations from standard posttransplant protocols. This is the first study to report the incidence and clinical impact of hyperkalemia following heart transplantation.

    We retrospectively included patients who underwent heart transplantation at our institution between April 2014 and December 2018. Patients with multiorgan transplantation were excluded. Clinical outcomes of patients who had serum potassium >5.5 mEq/L in the first year posttransplant (HK group) were compared to patients who did not have serum potassium >5.5 mEq/L in the first year posttransplant (non-HK group).

    A total of 143 patients were included in this study. During the first year posttransplant, cumulative incidence of serum potassium >5.0, >5.5, and >6.0 mEq/L was 96%, 63%, and 24%, respectively. Fifty-five percent of patients required treatment with potassium-chelating agents. Sulfamethoxazole-trimethoprim was discontinued because of HK in 39% of patients. Overall survival of patients in the HK group (n= 89) was comparable to that of patients in the non-HK group (n= 54, 91% vs 98% at 1 year, P= .19), whereas infection-free survival was significantly lower in the HK group (34% vs 53% at 1 year, P= .010). Multivariate analysis revealed pretransplant renal dysfunction (odds ratio= 2.62; 95% confidence interval, 1.18-5.80; P= .018) and use of mechanical circulatory support (odds ratio= 2.90; 95% confidence interval, 1.08-7.76; P= .035) as significant predictors of posttransplant hyperkalemia.

    The incidence of HK following heart transplantation was high, with more than half of patients requiring any therapeutic interventions, and HK was related to an increase in infection events.

    Deceased-donor kidney quality pretransplantation is considered critical for future graft function. Assessment of donor kidney quality considers clinical and histologic variables. Several models that incorporate a variety of these factors have been proposed to predict long-term graft survival.

    We compared the performance metrics of 4 scoring systems models—the Maryland Aggregate Pathology Index, Banff, Remuzzi, and Leuven—for predicting renal allograft survival. In this retrospective cohort study, we analyzed 173 renal allografts that underwent preoperative baseline biopsy. Donor demographics and donor baseline histopathology data were collected and correlated with graft survival posttransplant.

    Among the 4 scoring systems, none were significantly associated with posttransplant graft survival or early graft function. The Maryland Aggregate Pathology Index scoring system had better predictive capacity in receiver operating characteristic curve analysis; however, the utility as a predictor of graft survival was only slightly better than chance. Baseline histologic features were individually analyzed, and it was found that none were associated with graft survival in this cohort. Among donor demographics, none were significantly associated with graft survival.

    In our study none of the 4 previously proposed predictive models were associated with graft survival after transplantation. Further studies are needed to define new models with stronger predictive value for graft outcome that could help minimize organ discards.
