Cancer immunotherapy, especially the use of checkpoint inhibitors, is expanding and can be efficacious in organ transplant recipients with malignant neoplasia. In this review, we summarize clinical findings and evolution of several patients treated with CTL4-4 or PD-1 inhibitors reported in the literature. The CTL-4 inhibitor ipilimumab has been safely used in several liver and kidney allograft recipients. PD1-inhibitors look promising for tumor shrinking, but acute rejection is the rule, so they should be avoided in recipients of life-saving organs...

Although calcineurin inhibitor drugs have been the mostly used therapy in modern immunosuppression in kidney transplantation, their effect on kidney allograft dysfunction has been suboptimal as far as preservation of kidney function is concerned. Additionally, there are metabolic and other nonmetabolic effects including increased risk of malignancy that has necessitated the use of mammalian target of rapamycin inhibitors to reduce exposure to calcineurin inhibitors. Mammalian target of rapamycin inhibitors, both sirolimus and everolimus, have been studied in several trials to facilitate preservation of kidney function with variable effects on kidney allograft function and immunogenicity...

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...

BACKGROUND: Transplant recipients are treated with immunosuppressive (IS) therapies, which impact host-microbial interactions. We examined the impact of IS drugs on gut microbiota and on the expression of ileal antimicrobial peptides. METHODS: Mice were treated for 14 days with prednisolone, mycophenolate mofetil, tacrolimus, a combination of these 3 drugs, everolimus or water. Faeces were collected before and after treatment initiation. Ileal samples were collected after sacrifice...

INTRODUCTION: Patient and pancreas allograft survival improved following reductions in surgical complications, tighter donor selection and optimization in immunosuppressive protocols. However, long-term survival of pancreas allografts is adversely affected by rejection and immunosuppressive regimen toxicity. AREAS COVERED: This article reviews the existing literature and knowledge of mammalian target of rapamycin inhibitors (mTORi). Some clinically relevant drug-drug interactions are highlighted...

Left ventricular hypertrophy (LVH) regression after kidney transplantation may be influenced by immunosuppression. In a 24-month open-label, multicenter, phase-IV study, 71 kidney allograft recipients without previous acute rejection, showing eGFR >40 ml/min and proteinuria <500 mg/day and between 6 months and 3 years post-transplantation, were randomized to receive everolimus (EVR) + mycophenolic acid (MPA) or were maintained on tacrolimus (TAC) + MPA. The aim was to assess whether the conversion to EVR could reduce left ventricular mass index (LVMi) at month-24...

In renal transplantation, use of calcineurin inhibitors (CNIs) is associated with nephrotoxicity and immunosuppression with malignancies and infections. This trial aimed to minimize CNI exposure and total immunosuppression while maintaining efficacy. We performed a randomized controlled, open-label multicenter trial with early cyclosporine A (CsA) elimination. Patients started with basiliximab, prednisolone (P), mycophenolate sodium (MPS), and CsA. At 6 months, immunosuppression was tapered to P/CsA, P/MPS, or P/everolimus (EVL)...

Tuberous sclerosis complex (TSC) is a relatively rare genetic disorder, affecting one in 6,000 births. Mammalian target of rapamycin (mTOR) inhibitors, such as everolimus, which have been previously used to prevent solid organ transplant rejection, augment anticancer treatment regimens, and prevent neovascularization of artificial cardiac stents, are now approved for treating TSC-related manifestations, such as subependymal giant cell astrocytomas and renal angiomyolipomas. The use of everolimus in treating subependymal giant cell astrocytomas is supported by long-term Phase II and III clinical trials...

BACKGROUND: End-stage renal disease is a long-term irreversible decline in kidney function requiring renal replacement therapy: kidney transplantation, haemodialysis or peritoneal dialysis. The preferred option is kidney transplantation, followed by immunosuppressive therapy (induction and maintenance therapy) to reduce the risk of kidney rejection and prolong graft survival. OBJECTIVES: To review and update the evidence for the clinical effectiveness and cost-effectiveness of basiliximab (BAS) (Simulect(®), Novartis Pharmaceuticals UK Ltd) and rabbit anti-human thymocyte immunoglobulin (rATG) (Thymoglobulin(®), Sanofi) as induction therapy, and immediate-release tacrolimus (TAC) (Adoport(®), Sandoz; Capexion(®), Mylan; Modigraf(®), Astellas Pharma; Perixis(®), Accord Healthcare; Prograf(®), Astellas Pharma; Tacni(®), Teva; Vivadex(®), Dexcel Pharma), prolonged-release tacrolimus (Advagraf(®) Astellas Pharma), belatacept (BEL) (Nulojix(®), Bristol-Myers Squibb), mycophenolate mofetil (MMF) (Arzip(®), Zentiva; CellCept(®), Roche Products; Myfenax(®), Teva), mycophenolate sodium (MPS) (Myfortic(®), Novartis Pharmaceuticals UK Ltd), sirolimus (SRL) (Rapamune(®), Pfizer) and everolimus (EVL) (Certican(®), Novartis) as maintenance therapy in adult renal transplantation...

BACKGROUND: Recent studies suggest that the combination of tacrolimus (TAC) and everolimus (EVL) could become a viable option for use as standard maintenance immunosuppression in non-highly sensitized kidney transplant recipients. METHODS: We conducted a single-center, open-label, randomized pilot trial comparing two maintenance immunosuppression regimens in non-highly sensitized, adult, primary kidney transplant recipients: (TAC/EVL, Group A) vs our standard maintenance regimen of TAC plus enteric-coated mycophenolate mofetil (TAC/EC-MPS, Group B)...

Malignancy is the second most common single cause of death observed in organ transplant recipients. The excess cancer risk is related to intensity and duration of immunosuppressive therapy and inversely to recipient age. Immunodeficiency and (chronic/oncogenic) viral infections together constitute a major risk. Nonmelanoma skin cancer, Kaposi sarcoma and posttransplant lymphoproliferative disease (PTLD) have standardized incidence ratios exceeding 10- or 50-fold. The mammalian target of rapamycin (mTOR) inhibitors, sirolimus and everolimus, are increasingly used after organ transplantation with potential advantages in virus-associated post-transplant malignancies as well as anti-cancer properties...

OBJECTIVE: To explore the molecular mechanisms of resistance to phosphatidyl inositol 3-kinase (PI3K) inhibitors in triple-negative breast cancer (TNBC) cells. METHODS: HCC70 cells (TNBC) were transfected with siFZD7, siWANT5B or siGSK3 using lipofectamine 2000 transfection reagent. The expression levels of key proteins of WNT/β-catenin and PI3K/AKT/mTOR pathways were determined by Western blot analysis. After HCC70, MCF-7 (ER-positive) and SK-BR3 (HER2-positive) cells were treated with PI3K/AKT/mTOR inhibitors, the inhibition rates of cell proliferation were measured by MTT assay, and half maximal inhibitory concentrations (IC50) were calculated...

Orthotopic liver transplantation (OLT) is the recommended treatment for patients at early stages of hepatocarcinoma (HCC) with potential portal hypertension and/or bilirubinemia, but without vascular-associated diseases. The patients are receiving immunosuppressive therapy to reduce graft rejection, but differential side effects have been related to calcineurin and mTOR inhibitor administration regarding tumor recurrence and nephrotoxicity. The in vitro studies showed that Tacrolimus exerted a more potent pro-apoptotic effect than Everolimus (Huh 7>Hep 3B>HepG2), being sirolimus only active in Hep3B cell line...

We present the case of a 73-year-old male patient who had received a first renal transplant at 36 years and a second one at the age of 55 years. He is currently under immunosuppression with everolimus 2.5 mg/day and prednisone 5 mg/day. The patient presented with multiple actinic keratoses on both cheeks and the forehead and received treatment by ingenol mebutate 150 µg/g gel daily on 3 consecutive days on his right cheek and methyl aminolevulinate (MAL) photodynamic therapy activated by daylight (MAL-dPDT) on the forehead and the left cheek...

BACKGROUND: Kaposi sarcoma (KS) is a cancer with an incidence in patients after transplantation (Tx) that is 500 times greater than that in the healthy population. The risk of KS increases significantly during therapy, especially when immunosuppressive therapy with cyclosporine A (CsA) is used. Most cases of KS develop during the first 2 years after transplantation. After a KS diagnosis, it is recommended to reduce the doses of immunosuppressive medications. Conversion of immunosuppressive treatment into mammalian target of rapamycin (m-TOR) inhibitors is strongly suggested...
