Abstract
BACKGROUND Immunosuppressive medications play a crucial role in determining both organ and patient survival following liver transplantation (LT). Typically, immunosuppressive protocols for pediatric LT patients rely on calcineurin inhibitors (CNIs). While inhibitors of mammalian target of rapamycin (mTOR) have demonstrated beneficial outcomes in adult recipients of liver allografts, such as improved renal function post-LT, their application in pediatric liver transplant recipients is a subject of debate due to uncertain efficacy and potential adverse effects. OBJECTIVES This review evaluates the potential roles of mTOR inhibitors in the context of pediatric LT patients. METHODS This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol for conduct and reporting. Databases until 31 August 2023 were searched using specific terms and keywords. All clinical studies focusing on mTOR inhibitors in pediatric LT were included. RESULTS Out of 888 identified articles, 30 studies, involving 386 children who had undergone liver transplantation and received mTOR-inhibitor-based immunosuppressive regimens, met the inclusion criteria. The beneficial impacts of switching from a CNI to an mTOR inhibitor or adding an mTOR inhibitor to CNI-reduced immunosuppression in LT pediatric patients with impaired kidney function are controversial, and high-powered clinical studies are need. It appears that enhancing immunosuppression by adding an mTOR inhibitor to CNI is helpful for pediatric LT recipients who are experiencing refractory acute rejection or chronic rejection. mTOR-inhibitor-containing regimens failed to reduce the occurrence of post-transplant lymphoproliferative disorders (PTLD) among children with LT that may be due to concomitant high CNI concentration among studied patients. The effectiveness of mTOR inhibitors in treating PTLD remains uncertain; however, in patients with PTLD who are at high risk of rejection, mTOR inhibitors may be administered. Conversion to or the addition of mTOR inhibitors to maintenance immunosuppression seems to be suitable for pediatric patients who received a transplant due to hepatic malignancies such as hepatoblastoma or hepatocellular carcinoma or for those with post-transplant primary or recurrent malignancies. Switching to an mTOR inhibitor may improve some CNI-related adverse effects such as gingival hyperplasia, neurotoxicity, nephropathy, hypertrophic cardiomyopathy, or thrombotic microangiopathy. CONCLUSION Although the exact role of mTOR inhibitors among pediatric patients who have received a liver transplant needs further study, two algorithms are presented in this review to guide conversion from CNIs to mTOR inhibitors or the addition of mTOR inhibitor to a CNI-minimization immunosuppressive regimen for pediatric patients who may benefit from this class of drugs. This review mainly consisted of retrospective studies with inadequate sample sizes and lacked a control group, which represents the main limitation of this study.

Abstract
BACKGROUND AND AIMS To report 5-year outcomes of the CERTITUDE study. METHODS An observational study in patients with liver transplantation (LTx) compared the long-term impact of immunosuppression (with/without a calcineurin inhibitor) on renal function, cancers, major cardiovascular events (MACEs) and other safety parameters. All patients completing the 6-month SIMCER study were recruited and analysed according to treatment received at randomization and actual treatment received during the follow-up. RESULTS Of the 143 enrolled patients, 119 completed the 5-year follow-up (everolimus [EVR], n = 55; tacrolimus [TAC], n = 64). The mean absolute change in estimated glomerular filtration rate was not statistically different between both groups (TAC, -15.53 ml/min/1.73 m2 and EVR, -14.56 ml/min/1.73 m2 ). In the treatment subgroups based on actual treatment received, renal function was preserved better in the EVR subgroup compared with other subgroups (p = .051). Treated biopsy-proven acute rejection was higher in the EVR group (15.4% vs. 6.4%); however, the majority of events were mild in severity. MACE occurred in 9.2% vs. 14.1% of patients in the EVR and TAC groups respectively (p = .370). De novo cancer was reported in 14 and 5 patients in EVR and TAC groups respectively. Hepatocellular carcinoma (HCC) recurrence was observed in the TAC group alone (n = 4). Adverse events and treatment discontinuation owing to an adverse event were higher in the EVR group. CONCLUSIONS The CERTITUDE study demonstrated that EVR- and TAC-based regimens have comparable efficacy, safety and tolerability up to 5 years post-LTx.

Abstract
Immunosuppressive therapy (IMT) is the cornerstone of treatment after transplantation. The goal of immunosuppression is to prevent acute and chronic rejection while maximizing patient survival and long-term graft function. However, the expected effects of IMT must be balanced against the major adverse effects of these drugs and their toxicity. The purpose of this review is to summarize world experience on current immunosuppressive strategies and to assess their effects on renal function.

Abstract
One third of cirrhotic patients present impaired kidney function. It has multifactorial causes and has a harmful effect on patients' morbi-mortality before and after liver transplant. Kidney function does not improve in all patients after liver transplantation and liver-transplant recipients are at high risk of developing chronic kidney disease. Causes for renal dysfunction can be divided in three groups: preoperative, peroperative and postoperative factors. To date, there is no consensus for the modality of evaluation the risk for chronic kidney disease after liver transplantation, and for its prevention. In the present review, we describe the outcome of kidney function after liver transplantation, and the prognostic factors of chronic kidney disease to determine a risk stratification for each patient. Furthermore, we discuss therapeutic options to prevent kidney dysfunction in this setting, and highlight the indications of combined liver-kidney transplantation.

Abstract
Objective To analyze the diagnosis and treatment of patients with concomitant malignant tumors after organ transplantation by compiling data from organ transplantation patients. Methods By searching CNKI and PubMed databases, we made a systematic analysis of the studies of postorgan transplantation complicating malignant tumors in the last decade. Results There were 10 articles on malignant tumors after renal transplantation, 8 articles on liver transplantation, 2 articles on heart transplantation, and 1 article on lung transplantation. The incidence of malignant tumors complicating renal transplantation is 10.4% in Europe, with skin cancer and Kaposi's sarcoma being common; the incidence in the United States is 3.4%, with PTLD having the highest incidence; the incidence of malignant tumors is relatively lowest in Asia, with gastrointestinal malignancies being the main ones. The mean time to complication of malignancy after renal transplantation is 3.83 years. The incidence of concurrent malignancies after liver transplantation is 8.8% in Europe, where skin cancer and Kaposi's sarcoma are common; 5.6% in Asia, where gastrointestinal tract tumors are prevalent; and 4.5% in the United States, where gastrointestinal tract tumors, PTLD, and hematologic diseases are predominant. The mean time to complication of malignancy after liver transplantation is 4.79 years. The incidence of malignancy after heart transplantation is 6.8-10.7%. The incidence of malignancy after lung transplantation is about 10.1%. Minimization of immunosuppression or modification of immunosuppression regimens may be a key component of cancer prevention. mTOR inhibitors and phenolate (MMF) reduce the incidence of de novo malignancies in patients after solid organ transplantation. Surgical treatment improves survival in patients with early malignancies. The use of external beam radiation therapy in the treatment of hepatocellular carcinoma is limited due to the risk of radiation liver disease. Conclusions The risk of concomitant malignancy needs to be guarded for 5 years of immunosuppressive therapy after organ transplantation surgery. Adjusting the immunosuppressive treatment regimen is an effective way to reduce concurrent malignancies. Systemic chemotherapy or radiotherapy requires vigilance against the toxic effects of drug metabolism kinetics on the transplanted organ.

Abstract
The development of chronic kidney disease (CKD) after liver transplantation (LT) exerts a severe effect on the survival of patients. The widespread adoption of the model for end-stage liver disease score strongly impacted CKD incidence after the procedure, as several patients are transplanted with previously deteriorated renal function. Due to its multifactorial nature, encompassing pre-transplantation conditions, perioperative events, and nephrotoxic immunosuppressor therapies, the accurate identification of patients under risk of renal disease, and the implementation of preventive approaches, are extremely important. Methods for the evaluation of renal function in this setting range from formulas that estimate the glomerular filtration rate, to non-invasive markers, although no option has yet proved efficient in early detection of kidney injury. Considering the nephrotoxicity of calcineurin inhibitors (CNI) as a factor of utmost importance after LT, early nephroprotective strategies are highly recommended. They are based mainly on delaying the application of CNI during the immediate postoperative-period, reducing their dosage, and associating them with other less nephrotoxic drugs, such as mycophenolate mofetil and everolimus. This review provides a critical assessment of the causes of renal dysfunction after LT, the methods of its evaluation, and the interventions aimed at preserving renal function early and belatedly after LT.

Abstract
De novo malignancies (DNMs) following liver transplantation (LT) have been reported as 1 of the major causes of late mortality, being the most common cause of death in the second decade after LT. The overall incidence of DNMs is reported to be in the range of 3.1% to 14.4%, and the incidence is 2- to 3-fold higher in transplant recipients than in age- and sex-matched healthy controls. Long-term immunosuppressive therapy, which is the key in maintaining host tolerance and achieving good long-term outcomes, is known to contribute to a higher risk of DNMs. However, the incidence and type of DNM also depends on different risk factors, including patient demographics, cause of the underlying chronic liver disease, behavior (smoking and alcohol abuse), and pre-existing premalignant conditions. The estimated standardized incidence ratio for different DNMs is also variable. The International Liver Transplantation Society-Spanish Society of Liver Transplantation Consensus Conference working group on DNM has summarized and discussed the current available literature on epidemiology, risk factors, management, and survival after DNMs. Recommendations for screening and surveillance for specific tumors, as well as immunosuppression and cancer-specific management in patients with DNM, are summarized.

Abstract
Immunosuppressant is a class of medicines that inhibit or decrease the intensity of the immune response in the body. Most of these medications are used to allow the body less likely to resist a transplanted organ. In solid organ transplantation, immunosuppressive agents are needed for the activation of early-stage immunosuppression, the management of late-stage immunosuppression or for the maintenance of organ rejection. The emergence of novel agents and improvements in immunosuppression regimens after transplantation are significant factors leading to this progress. However, these drugs also increase the risk of infection, cancers and specific adverse side effects specific to each agent in patients particularly in pregnant women and fertility issues. Corona virus disease being hot topic of debate is has given positive outcome to immunosuppressive drugs however need more attention in future. Transplant centers across the world utilize multiple immunosuppression protocols; nevertheless, each patient can require an individually formulated immunosuppression regimen to manage the advantages and possible damage of treatment thus eliminating the likelihood of their primary disease recurrence.

Abstract
One-third of patients with cirrhosis present kidney failure (AKI and CKD). It has multifactorial causes and a harmful effect on morbidity and mortality before and after liver transplantation. Kidney function does not improve in all patients after liver transplantation, and liver transplant recipients are at a high risk of developing chronic kidney disease. The causes of renal dysfunction can be divided into three groups: pre-operative, perioperative and post-operative factors. To date, there is no consensus on the modality to evaluate the risk of chronic kidney disease after liver transplantation, or for its prevention. In this narrative review, we describe the outcome of kidney function after liver transplantation, and the prognostic factors of chronic kidney disease in order to establish a risk categorization for each patient. Furthermore, we discuss therapeutic options to prevent kidney dysfunction in this context, and highlight the indications of combined liver–kidney transplantation.

Abstract
INTRODUCTION AND AIM The interleukin-2 receptor antagonist; basiliximab is used to allow delayed introduction of Calcineurin inhibitors (CNI) after liver transplantation and thus delay their renal insult. However, there is only little evidence for the safety and the efficacy of this regimen. This study aimed to evaluate the effectiveness and safety of basiliximab induction in liver transplantation. MATERIALS AND METHODS This study included 89 patients who were classified into two groups: standard triple immunosuppression (IS) regimen of steroid, tacrolimus (TAC) and mycophenolate mofetil (MMF) (n = 47) and induction IS regimen of basiliximab, low dose steroids and MMF with delayed introduction of CNI (n = 42). All patients were followed after liver transplantation for at least six months or until death. RESULTS There were no significant differences in patient survival, graft dysfunction, infection rate or type, or wound healing between both groups. The acute rejection rate was equivalent in both groups. Renal dysfunction in the first six months post-transplant was less in the basiliximab group in comparison to the other group (7.1% and 19.1% respectively). CONCLUSION Basiliximab-induced IS protocol is a safe regimen that reduces medium-term renal dysfunction and achieves similar survival without increasing the acute rejection or infection rate in liver transplantation recipients.

Abstract
Background: Mammalian target of rapamycin (mTOR) inhibitors, such as everolimus and sirolimus, may be efficacious in preserving renal function in liver transplantation (LT) recipients while preventing hepatocellular carcinoma (HCC) recurrence. Materials and Methods: In this study, we retrospectively evaluated the safety, efficacy, and renoprotective effects of mTOR inhibitors in LT recipients. Among the 84 patients enrolled, mTOR inhibitor was commenced during the first year after LT. Renal function was measured by estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease equation. Results: Regarding the type of mTOR inhibitor, everolimus was used in 71 patients and sirolimus in 13 patients. Concomitant tacrolimus was used in 63 patients (75.0%). For total enrolled patients, kidney function did not significantly change during 12 months after initiation of mTOR inhibitors, although tacrolimus-withdrawn patients (n = 21) showed better kidney function compared to tacrolimus-minimized patients (n = 63) after conversion. However, a significant improvement in kidney function was observed in the eGFR <60 ml/min/1.73 m2 group (n = 19) 12 months after initiation of mTOR inhibitors, for both patient groups with early + mid starters (n = 7, stating within 1 year after LT) and late starters (n = 12, starting over 1 year after LT). mTOR inhibitors were safely administered without serious adverse events that led to drug discontinuation. Conclusion: We demonstrated that patients with renal impairment showed significant improvement in renal function regardless of the timing of mTOR inhibitor start, suggesting that switch to mTOR inhibitors may be beneficial when renal function declines.

Abstract
BACKGROUND Information on the risk factors, particularly kidney function, and impact of long-term cardiovascular events (CVE) after liver transplantation (LT) remains scarce. METHODS This is a retrospective, single-center study that included consecutive LT recipients between 2007 and 2017. The incidence of CVE, their risk factors, and their impact on patient survival were investigated. RESULTS We included 627 LT recipients. The incidence of CVE was 8% and 20% at 12 and 60 months after LT, respectively. The independent risk factors of long-term (beyond 12 mo) CVE were age at LT (hazard ratio [HR], 1.04; 95% confidence interval [CI], 1.01-1.07), male gender (HR, 2.48; 95% CI, 1.21-5.05), history of pre-LT cardiovascular disease (HR, 2.19; 95% CI, 1.2-3.98), and immunosuppression with cyclosporine A (HR, 1.93; 95% CI, 1.14-3.3). In patients with pre-LT cardiovascular disease, creatinine levels 12 months after LT significantly impacted the risk of long-term CVE. Long-term CVE (HR, 2.12; 95% CI, 1.24-3.61), hepatitis C as the etiology of liver disease (HR, 2.18; 95% CI, 1.29-3.67), cytomegalovirus infection (HR, 1.89; 95% CI, 1.08-3.3), and donor age (HR, 1.02; 95% CI, 1.01-1.04) were independent factors associated with post-LT patient death. CONCLUSIONS Age, male gender, cardiovascular disease before LT, and cyclosporine A were associated with the risk of long-term CVE. The impact of serum creatinine was restricted to patients with pre-LT cardiovascular disease. In these patients, preservation of kidney function early after LT may lessen the incidence of CVE, which are an independent predictor of post-LT death.

Abstract
The increasing potency of immunosuppression (IS) agents resulted in significantly decreased rates of steroid resistant rejection and rejection related graft loss in liver transplantation (LT). Currently, more than two thirds of late mortality after LT is unrelated to graft function. However, the increased benefit of more potent IS drugs, coupled with the prolonged survival of transplant recipients led to longer patients exposure to these drugs and their unwanted adverse effects, creating a double-edged sword. In this article the authors describe the mechanism of action and the adverse effects of the most commonly used immunosuppressed drugs, and the most commonly used IS regimens for both induction and maintenance regimens. The balance between the ideal IS regimen to prevent rejection and the need to minimize the dose of IS drugs in order to prevent the adverse effects related to its use requires the knowledge of the science and the experience with the art of medicine. The different protocols aimed at protecting renal function and preventing the development of de novo cancer and metabolic syndrome are discussed here. The main causes of mortality late after liver transplant are associated with prolonged use of IS medications, and clear evidence exists about over-immunosuppression of recipients of liver transplant. The current status of strategies of IS minimization and withdrawal are reviewed in this article, with evaluation of its benefits and pitfalls.

Abstract
BACKGROUND Mammalian target of rapamycin (mTOR) inhibitors following liver transplantation (LT) are used to minimize calcineurin inhibitor (CNI)-related nephrotoxicity. Data about metabolic effects of mTOR inhibitors are still limited. AIM This study aims to determine the renal and metabolic effects of different mTOR inhibitor-based protocols in real-life LT patients. METHODS This is a retrospective cohort study of patients treated with mTOR inhibitors after LT. Demographics, treatment protocols, glomerular filtration rate (GFR), and metabolic parameters were collected over a period of 4 years. Initiation of blood pressure (BP), diabetes mellitus, and lipid medications was also noted. RESULTS Fifty-two LT recipients received mTOR inhibitors. GFR improved significantly (by 1.96 mL/min/year), with greater improvement in patients with baseline renal dysfunction (+13.3 mL/min vs +4.5 mL/min at 3 years). Conversion to an mTOR inhibitor during the first post-transplant year resulted in a more durable improvement in GFR (for 4 years vs only 1 year for later conversion).No significant weight gain or new-onset diabetes mellitus was observed. However, there was some increase in total cholesterol (+7 mg/dL) and blood pressure (+2 mm Hg during the third year and +8 mm Hg in the fourth years), followed by initiation of lipid-lowering and BP medications in 25% and 13% of patients, respectively. CONCLUSIONS Treatment with an mTOR inhibitor following LT resulted in improved kidney functions without significant negative metabolic effects such as weight gain or new-onset diabetes mellitus. This makes mTOR inhibitors a valuable immunosuppressive option in the face of the growing incidence of nonalcoholic steatohepatitis as a leading cause for LT.

Abstract
BACKGROUND Calcineurin inhibitors have been implicated in acute and chronic kidney disease after liver transplant (LT). Everolimus (EVR) is a mammalian target of rapamycin inhibitor efficacious in preventing acute cellular rejection while preserving renal function among LT recipients. We evaluated the benefits on renal function of EVR immunosuppression in LT recipients. METHODS We performed a retrospective and observational study in 477 LT recipients in Virgen de las Nieves Hospital from 2002 to 2019 on the use of EVR with tacrolimus minimization or withdrawal in LT recipients with renal dysfunction. The study included 100 patients starting EVR (20.96%); in 66 (66%) the indication was renal dysfunction. The change in renal function was assessed by estimated glomerular filtration rate. Statistical analyses were performed using SPSS 17.0 software (IBM, Munich, Germany). RESULTS Fifty 8 patients received mycophenolate mofetil (87.8%), and tacrolimus therapy was stopped in 27 patients (40.9%). Induction therapy with basiliximab was administered in 41 patients (62.12%). There was significant difference between estimated glomerular filtration rate at the time of starting EVR and the first month at last follow-up (49.42 mL/min/1.73 m2 vs 75.27 mL/min/1.73 m2; P < .001) and at end of follow-up (24 months) (49.42 mL/min/1.73 m2 vs 64.32 mL/min/1.73 m2; P = .001). The rate of incidence of adverse events was 48.48% (32/66). Seven patients died during follow-up (10.6%), but there were no EVR-related deaths. Eleven patients (16.6%) developed biopsy-proven acute rejection. CONCLUSION This study showed that EVR is associated with a beneficial effect on glomerular filtration rate in both the short and long term in LT recipients.

Abstract
Autophagy modulation is considered to be a promising programmed cell death mechanism to prevent and cure a great number of disorders and diseases. The crucial step in designing an effective therapeutic approach is to understand the correct and accurate causes of diseases and to understand whether autophagy plays a cytoprotective or cytotoxic/cytostatic role in the progression and prevention of disease. This knowledge will help scientists find approaches to manipulate tumor and pathologic cells in order to enhance cellular sensitivity to therapeutics and treat them. Although some conventional therapeutics suffer from poor solubility, bioavailability and controlled release mechanisms, it appears that novel nanoplatforms overcome these obstacles and have led to the design of a theranostic-controlled drug release system with high solubility and active targeting and stimuli-responsive potentials. In this review, we discuss autophagy modulators-related signaling pathways and some of the drug delivery strategies that have been applied to the field of therapeutic application of autophagy modulators. Moreover, we describe how therapeutics will target various steps of the autophagic machinery. Furthermore, nano drug delivery platforms for autophagy targeting and co-delivery of autophagy modulators with chemotherapeutics/siRNA, are also discussed.

Abstract
In recent years, the use of mammalian target of rapamycin inhibitors has gained traction in their use as alternative or adjunct immunosuppressants in the post-liver transplantation (LT) setting. The efficacy of everolimus (EVR) in de novo LT is established and a reasonable time to initiate EVR is 30 d from LT surgery. Initiating EVR early post-LT allows for calcineurin inhibitor (CNI) reduction, thus reducing nephrotoxicity in LT recipients. However, data is inadequate on the appropriate timing for conversion from CNI to EVR maintenance in order to achieve optimal renoprotective effect without compromising drug efficacy. Adverse effects of proteinuria, hypercholesterolemia and hyperlipidemia are significantly higher as compared to standard CNI and long-term implications on graft and patient survival in LT is still unclear. Future research to explore strategies to minimise EVR adverse effects will be crucial for the success of EVR as an important alternative or adjunct immunosuppressive therapy in LT.

Abstract
Mammalian target of rapamycin (mTOR) inhibitors, everolimus (EVL) and sirolimus are immunosuppressive agents with a minor nephrotoxic effect, limited to the development of proteinuria in some cases. The combination of EVL and low-dose tacrolimus has proven to be as safe and effective as standard therapy with tacrolimus for the prevention of acute cellular rejection. Early initiation of EVL-based immunosuppressive regimens with reduced exposure to calcineurin inhibitors has been shown to significantly improve renal function of LT recipients during induction and maintenance phases, with comparable efficacy and safety profiles. In patients with established kidney failure, initiating EVL may enable clinicians to reduce calcineurin inhibitors exposure, thereby contributing to the improved renal function of these patients. Although there is not sufficient evidence to recommend their use to prevent the recurrence of hepatocellular carcinoma and the progression of de novo tumours, they are used in this context in routine clinical practice.

Abstract
Our aim was to study the safety and efficacy of immunosuppression with everolimus (EVL) within the 1st month after orthotopic liver transplantation (LT) when calcineurin inhibitors are not recommended. For this purpose, 28 recipients who had been treated with EVL within the 1st month after adult LT were eligible to enter in a retrospective multicenter study. Patients were followed up for 12 months after LT. EVL therapy was initiated at a median of 14 days (range, 4-24) after LT. The reason for early EVL was neurotoxicity in 14 cases, renal dysfunction in 12, and acute cellular rejection combined with renal impairment in 2. In 23 patients, immunosuppression was EVL + mycophenolate mofetil/mycophenolate sodium + steroids, and EVL + tacrolimus + steroids/mycophenolate sodium was used in 4 cases. Neurotoxicity disappeared in all patients. Renal function in patients with renal impairment improved from a median of 32 mL/min/1.73 m2 at the moment of implementation of EVL to 62 mL/min/1.73 m2 at 1 year. Four patients (14.3%) developed acute cellular rejection. We observed incisional hernia in 4 patients (14.3%), hematologic complications in 6 (21.4%), proteinuria in 2 (7.1%), edema and/or effusions in 8 (28.6%), and dyslipidemia in 12 (42.8%). No arterial complications were observed. EVL was withdrawn in 5 patients during the 1st year after LT. One-year patient survival was 92.7%. In conclusion, use of EVL within the 1st month after LT when calcineurin inhibitors are not recommended seems to be an effective therapeutic option with an acceptable safety profile.

Abstract
Management of complications post-liver transplantation (LT) includes immunosuppressive manipulations with the aim to reduce the overall burden of immunologic suppression and compensate for renal, cardiovascular, metabolic toxicities, and for the increased oncologic risk. Two approaches can be implemented to reduce immunosuppression-related adverse events: upfront schedules tailored to the pretransplant individual patient's risk profile versus downstream modifications in the event of immunosuppression-related complications. Upfront strategies are supported by evidence originating from prospective randomized trials and consist of triple/quadruple schedules whereby calcineurin inhibitors (CNI)-exposure is reduced with combination of anti-CD25 monoclonal antibodies, antimetabolites and corticosteroids. Quadruple regimens allow for staggering of CNI introduction and higher renal function in the early term, but their superiority in the long term has not yet been established. A more recent upfront schedule contemplates early (4 weeks) introduction of mammalian target of rapamycin inhibitor (mTORi) everolimus and allows for reduction of CNI up to 4 years posttransplantation. Incorporation of mTORi has the potential to prolong time to recurrence for patients with hepatocellular carcinoma. However, as suggested by the available evidence, downstream immunosuppressive manipulations are more frequently adopted in clinical practice. These encompass CNI replacement and immunosuppression withdrawal. Switching CNI to mTORi monotherapy is the option most commonly adopted to relieve renal function and compensate for posttransplant malignancies. Its impact is dependent on interval from transplantation and underlying severity of renal impairment. Introduction of mTORi is associated with longer overall survival for patients with extrahepatic posttransplant malignancies, but results are awaited for recurrences of hepatocellular carcinoma. Immunosuppression withdrawal seems feasible (70%) in very long term survivors (>10 years), but is not associated with reversal of immunosuppression-related complications. Awaiting novel immunosuppressive drug categories, integration of upfront strategies with the aim to reduce CNI-exposure and a low threshold for adjustment in the posttransplant course are both advisable to improve long-term outcomes of LT.

Abstract
Calcineurin inhibitors (CNI) are the mainstay of immunosuppression after liver transplantation (LT), but CNIs are associated with significant nephrotoxicity. Recently, mTOR inhibitors such as sirolimus and everolimus (EVR) have been used with or without CNIs in LT recipients for their renal-sparing effect. We conducted a systematic review and meta-analysis of randomized controlled trials (RCT) that examined the effect of EVR with CNI minimization or withdrawal on renal function in LT recipients. RCT of primary adult LT recipients with baseline GFR >30 mL/min who received EVR with CNI minimization or withdrawal were included. Four RCTs (EVR n=465, control n=428) were included. In three RCTs, EVR was initiated 4 weeks following LT; these studies were used to assess the primary outcome. All four studies were used to assess the secondary outcomes. Based on this study, EVR use with CNI minimization in LT recipients is associated with improved renal function at 12 months by GFR of 10.2 mL/min (95% CI: 2.75-17.8). EVR use was not associated with an increased risk of biopsy-proven acute rejection (RR 0.68, 95% CI: 0.31-1.46), graft loss (RR 1.60, 95% CI: 0.51-5.00), or mortality (RR 1.34, 95% CI 0.62-2.90). However, it was associated with an increased risk of overall infections (RR 1.45, 95% CI: 1.10-1.91).

Abstract
Background: Hepatocellular Carcinoma (HCC) represents the fifth most common malignancy and the third cancer-related cause of death worldwide. Hepatitis B (HBV) and C (HCV) viral infections and alcohol abuse are the principal etiological factors for HCC. Liver transplantation (LT) is oncologically the preferable approach to HCC, as it can remove all the intrahepatic tumor foci, and also the oncogenic cirrhotic liver. The use of mTOR inhibitors (mTORi) for immunosuppression after LT for HCC has been proposed due to rapamycin antitumor activity. We decided to review the literature to clarify the oncological role of mTORi after liver transplantation for HCC, analyzing both present condition and future perspectives. Material and Methods: A systematic literature search was performed using PubMed, EMBASE, Scopus, and the Cochrane Library Central. The search was limited to studies in humans and to those reported in the English language in the period of time between January 2005 and December 2015. Results: The literature search yielded 93 articles; after duplicates were removed, 77 titles and abstracts were reviewed. Most relevant data and papers are herein reported and discussed. Conclusions: So far, the use of mTORi is encouraging in terms of oncological outcomes for patients underwent LT for HCC, both for prevention and treatment of HCC recurrence although definitive data are still awaited.

Abstract
Malignancy after solid organ transplantation remains a major cause of posttransplant mortality. The mammalian target of rapamycin (mTOR) inhibitor class of immunosuppressants exerts various antioncogenic effects, and the mTOR inhibitor everolimus is licensed for the treatment of several solid cancers. In kidney transplantation, evidence from registry studies indicates a lower rate of de novo malignancy under mTOR inhibition, with some potentially supportive data from randomized trials of everolimus. Case reports and small single-center series have suggested that switch to everolimus may be beneficial following diagnosis of posttransplant malignancy, particularly for Kaposi's sarcoma and nonmelanoma skin cancer, but prospective studies are lacking. A systematic review has shown mTOR inhibition to be associated with a significantly lower rate of hepatocellular carcinoma (HCC) recurrence versus standard calcineurin inhibitor therapy. One meta-analysis has concluded that patients with nontransplant HCC experience a low but significant survival benefit under everolimus monotherapy, so far unconfirmed in a transplant population. Data are limited in heart transplantation, although observational data and case reports have indicated that introduction of everolimus is helpful in reducing the recurrence of skin cancers. Overall, it can be concluded that, in certain settings, everolimus appears a promising option to lessen the toll of posttransplant malignancy.

Abstract
Both acute and chronic kidney disease are common after liver transplantation and result in significant morbidity and mortality. The introduction of the Model for End-stage Liver Disease score has directly correlated with an increased prevalence of perioperative renal dysfunction and the number of simultaneous liver-kidney transplantations performed. Kidney dysfunction in this population is typically multifactorial and related to preexisting conditions, pretransplantation renal injury, perioperative events, and posttransplantation nephrotoxic immunosuppressive therapies. The management of kidney disease after liver transplantation is challenging, as by the time the serum creatinine level is significantly elevated, few interventions affect the course of progression. Also, immunological factors such as antibody-mediated kidney rejection have become of greater interest given the rising liver-kidney transplant population. Therefore, this review, assembled by experts in the field and endorsed by the American Society of Transplantation Liver and Intestine Community of Practice, provides a critical assessment of measures of renal function and interventions aimed at preserving renal function early and late after liver and simultaneous liver-kidney transplantation. Key points and practice-based recommendations for the prevention and management of kidney injury in this population are provided to offer guidance for clinicians and identify gaps in knowledge for future investigations.
