Cholongitas E, Burra P, Vourli G, Papatheodoridis GV. Safety and efficacy of everolimus initiation from the first month after liver transplantation: A systematic review and meta-analysis. Clin Transplant 2023; 37:e14957. [PMID: 36880482 DOI: 10.1111/ctr.14957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 02/15/2023] [Accepted: 02/25/2023] [Indexed: 03/08/2023]
Abstract
INTRODUCTION Everolimus, a selective inhibitor of mamalian target of rapamycin (mTORi), is considered to be an alternative immunosuppressive regimen in the liver transplantation (LT) setting. However, most of the transplant centers avoid its early use (i.e., during the first month) after LT mainly due to safety issues. METHODS We searched for all articles published between 01/2010 and 7/2022 to evaluate the effectiveness and safety of initial/early administration of everolimus after LT. RESULTS Seven studies (three randomized controlled trials and four prospective cohort studies) were included: initial/early everolimus-including therapy (group 1) was used in 512 (51%) and calcineurin inhibitor (CNI) based therapy (group 2) in 494 (49%) patients. No significant difference was found between group 1 and group 2 patients regarding the rates of biopsy-proven acute rejection episodes (Odds Ratio [OR]: 1.27, 95% CI: .67-2.41, p = .465) and hepatic artery thrombosis (OR: .43, 95% CI: .09-2.02, p = .289). Everolimus was associated with higher rates of dyslipidemia (14.2% vs. 6.8%, p = .005) and incisional hernia (29.2% vs. 10.1%, p < .001). Finally, no difference was found between the two groups regarding recurrence of hepatocellular carcinoma (Risk Rates [RR]: 1.22 95%CI: .66-2.29, p = .524) and mortality (RR: .85 95%CI: .48-1.50, p = .570). CONCLUSION Use of initial/early everolimus seems to be effective with a satisfactory safety profile, making its administration a reasonable therapeutic option in the LT setting.

Cross-sectional analysis of immunosuppressive regimens focused on everolimus after liver transplantation in a Korean high-volume transplantation center. KOREAN JOURNAL OF TRANSPLANTATION 2019; 33:98-105.

Abstract
Background The mammalian target of the rapamycin inhibitor has dual inhibitory effects on cell growth and angiogenesis. This study aimed to analyze the usage of everolimus on actual immunosuppression (IS) regimens through a cross-sectional study in a high-volume liver transplantation (LT) center. Methods Our institutional LT database was searched for adult patients who underwent primary LT surgery between January 2010 and December 2016. We identified 2,093 LT recipients with observation periods of 1 to 8 years. Results We divided the 2,093 recipients into three groups according to the posttransplant follow-up period as follows: group A (12–36 months; n=680), group B (37–60 months; n=560), and group C (>60 months; n=853). The individual IS agents were tacrolimus in 1,807 patients (86.3%), cyclosporine in 169 patients (8.1%), mycophenolate mofetil (MMF) in 1,310 patients (62.6%), and everolimus in 115 patients (5.5%). The most common IS regimens were tacrolimus-MMF combination and tacrolimus monotherapy, regardless of the posttransplant period. Patients with pretransplant malignancies were administered everolimus more frequently than those without pretransplant malignancies (P<0.001). In 102 patients with hepatocellular carcinoma recurrence or de novo malignancies, IS regimens included everolimus-tacrolimus in 41 patients (40.2%), tacrolimus-MMF in 27 patients (26.4%), tacrolimus in 20 patients (19.6%), MMF in 10 patients (9.8%), cyclosporine in three patients (2.9%), and cyclosporine-MMF in one patient (1.0%). Conclusions Administration of everolimus after LT has been gradually increasing with the expansion of indications in our institutional practice. Currently, the role of everolimus is minimal and not comparable to that of tacrolimus, but it has a unique position in the field of IS after LT.

Abstract
Background This study evaluated the efficacy, safety, and impact on renal function of everolimus in patients after liver transplantation (LT) with or without mycophenolate mofetil (MMF). Methods We evaluated LT recipients with calcineurin inhibitor (CNI)-related renal dysfunction after everolimus initiation. Laboratory data, including evaluation of renal function based on glomerular filtration rate (GFR) at baseline (i.e., everolimus initiation) and at the end of follow up, were analyzed. Results Fifty consecutive patients started taking everolimus at 30 months post-LT (range: 1-240), 6 as monotherapy and 44 in combination with MMF. After 30.5 months (range: 6-112), all patients were alive, without any biochemical evidence of a rejection episode or recurrence of hepatocellular carcinoma. The mean GFR, based on the Modification of Diet in Renal Disease equation, was 53±13 mL/min at baseline and 59±12 mL/min at the end of follow up (P=0.031). Eleven (22%) of the patients had GFR <60 mL/min at baseline but returned to GFR >60 mL/min by the end of follow up. In multivariate analysis, the time between the development of renal dysfunction and everolimus initiation was the only factor independently associated with GFR improvement (odds ratio [OR] 0.85, 95% confidence interval [95%CI] 0.76-0.96; P=0.007). Everolimus was stopped in 11 patients (22%) at the end of follow up because of adverse events. Conclusion A CNI-free everolimus-based regimen was effective in LT recipients with renal dysfunction and was associated with an improvement in GFR.

Abstract
Backgrounds/Aims Long-term immunosuppression regimens after liver transplantation (LT) are rarely reported in detail. We aimed to provide information on actual long-term immunosuppression regimens through this cross-sectional study. Methods Our institutional LT database was searched for adult patients who underwent primary LT operation from 2000 to 2016. We identified 3620 live recipients with actual information on immunosuppressive agent use for 1-17 years. Results The study cohort was divided into 7 groups according to posttransplantation period. The immunosuppressive agents used at the cross-sectional review period were tacrolimus in 2884 (79.7%), cyclosporine in 445 (12.3%), mycophenolate mofetil in 2007 (55.4%), and everolimus in 138 (3.8%) recipients. There was no marked difference in immunosuppressive agent use according to pretransplantation liver malignancy or type of LT operation. Tacrolimus, cyclosporine, mycophenolate mofetil, and everolimus were used in 97.4%, 1.8%, 60.9%, and 9.2%, respectively, in the year 2 group; 94.1%, 3.9%, 51.6%, and 8.3%, respectively, in the year 3 group; 87.3%, 8.4%, 68.9%, and 4.8%, respectively, in the year 4-5 group; 78.2%, 12.9%, 64.6%, and 3.0%, respectively, in the year 6-7 group; 76.9%, 10.8%, 58.8%, and 2.4%, respectively, in the year 8-10 group; 66.7%, 22.4%, 43.4%, and 1.5%, respectively, in the year 11-15 group; and 73.8%, 15.4%, 32.9%, and 1.7%, respectively, in the year ≥15 group. Conclusions Tacrolimus and mycophenolate mofetil are the primary immunosuppressive agents after LT, and the indications for everolimus have started to increase at our institution. We believe our results will help establish tailored long-term immunosuppression regimens.

Drug-resistant epilepsy development following stem cell transplant and cyclosporine neurotoxicity induced seizures: Case report in an adult and analysis of reported cases in the literature. EPILEPSY & BEHAVIOR CASE REPORTS 2018; 10:8-13. [PMID: 30062084 PMCID: PMC6064196 DOI: 10.1016/j.ebcr.2018.01.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/07/2018] [Revised: 01/19/2018] [Accepted: 01/27/2018] [Indexed: 11/22/2022]
Abstract
Introduction Drug-resistant epilepsy (DRE) occurs in 20–30% of all patients who develop epilepsy and can occur from diverse causes. Cyclosporine-A (CSA) is an immunosuppressive drug utilized to prevent graft-versus-host disease (GvHD) in transplant patients and is known to cause neurotoxicity, including seizures. In some cases, however, patients can develop DRE. Only a limited number of cases have been reported in which DRE has developed after CSA exposure — all in children. Here we present a rare case of an adult developing DRE after post-transplant CSA neurotoxicity. In addition, we provide a comprehensive review and analysis of all reported cases in the literature. Case report A 29-year-old man with Non-Hodgkin's Lymphoma underwent an allogenic hematopoietic stem cell transplant and experienced a CSA-induced seizure at 7.5 months' post-transplant. The patient was discontinued on CSA and began a low dose tacrolimus regimen. At 33 months' post-transplant, he had seizure recurrence and developed DRE. Imaging revealed right mesial temporal sclerosis (MTS) and video EEG localized ictal activity to the right anterior temporal lobe. He was successfully treated with a right anterior temporal lobectomy and amygdalohippocampectomy. Literature review Seven peer-reviewed studies described 15 patients who underwent transplantation with post-transplant CSA administration and subsequently developed DRE following an initial CSA-induced seizure. All 15 patients were children suggesting that young age is a risk factor for DRE after CSA-induced seizures. Initial CSA-induced seizures occurred at an average of 1.6 ± 1.1 months after transplant and seizure recurrence 9.2 ± 8.0 months after transplant. All reported CSA routes of administration (n = 6) were intravenous and 7 of 9 (78%) reported CSA blood levels above the therapeutic range. The incidence of MTS (40%) in these 15 patients was significantly higher than the incidence in the general DRE population (24%) and was most effectively treated via epilepsy surgery. Conclusions The use of cyclosporine for GvHD prophylaxis and treatment following transplantation may cause seizures and be associated with DRE. Although discontinuation and dose decrease of CSA often reverse adverse neurological events, initial CSA-induced seizures may be associated with MTS that and subsequent greater risk of DRE development.

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.

Effect of Early Everolimus-Facilitated Reduction of Tacrolimus on Efficacy and Renal Function in De Novo Liver Transplant Recipients: 24-Month Results for the North American Subpopulation. Transplantation 2017; 101:341-349.

Abstract
Background A recent randomized phase III study of 719 de novo liver transplant recipients showed that early everolimus plus reduced-dose tacrolimus (EVR + rTAC) led to significantly better kidney function than standard TAC (TAC-C), without compromising efficacy. In that study, patients from North America (n = 211) had increased risk factors for posttransplant renal insufficiency at study start, relative to patients from Europe and rest of world (eg, worse renal function, more diabetes, older age). Methods A post hoc analysis was performed to assess whether these regional disparities affected study outcomes in North American patients. Results In this subpopulation, estimated glomerular filtration rates at randomization were higher in TAC-C over EVR + rTAC (76.4 vs 69.3 mL/min per 1.73 m2). Mean changes in estimated glomerular filtration rate values (mL/min per 1.73 m2) favored EVR + rTAC over TAC-C at months 12 (+3.7 vs −4.5; P = 0.032), 24 (+2.7 vs −6.6; P = 0.042), and 36 (+4.3 vs −8.1; P = 0.059). The composite efficacy endpoint of treated biopsy-proven acute rejection, graft loss, or death was 10.9%, 14.1%, and 14.1% for EVR + rTAC and 13.1%, 17.2%, and 19.3% for TAC-C at months 12, 24, and 36, respectively. Conclusions Although the North American cohort had more comorbidities, results were consistent with the overall population for efficacy and renal function. In order to reduce nephrotoxicity in liver transplantation, several strategies are being explored including early everolimus-facilitated tacrolimus dose reduction, which in a recent multicenter study led to better kidney function versus standard TAC without compromising efficacy. In this North American cohort sub-analysis, results are similar despite higher baseline comorbidities.
