INTRODUCTION: Lung transplantation (LT) is the standard of care for patients with advanced lung diseases, including lymphangioleiomyomatosis (LAM). LAM accounts for only 1% of all LTs performed in the international registry. As a result, the global experience, including the use of mechanistic target of rapamycin (mTOR) inhibitors before and after LT in LAM, is still limited. METHODS: We conducted a retrospective review of all LAM patients who underwent LT at our centre between 2003 and 2016...

BACKGROUND: Danon disease is an X-linked disturbance of autophagy manifesting with cognitive impairment and disordered heart and skeletal muscle. After a period of relative stability, patients deteriorate rapidly and may quickly become ineligible for elective heart transplantation - the only life-saving therapy. METHODS: We report a large pedigree with diverse manifestations of Danon disease in hemizygotes and female heterozygotes. RESULTS: Malignant cardiac arrhythmias requiring amiodarone treatment induced thyroid disease in two patients; intractable thyrotoxicosis, which enhances autophagy, caused the death of a 21year-old man...

Percutaneous coronary intervention (PCI) has become a standard treatment in patients with acute coronary syndrome. However, it is associated with endothelial cell denudation, which may predispose to in-stent thrombosis and restenosis. Pharmacological methods which prevent restenosis can delay post-PCI re-endothelialisation. We have therefore examined how atorvastatin (HMG-CoA reductase inhibitor), sirolimus and everolimus (mTOR inhibitors) affect young and old endothelial cell functions which are responsible for wound healing after PCI...

The relative long-term efficacy and safety of sirolimus-eluting stents (SES) compared with paclitaxel-eluting stents (PES) in multiple comparative studies remains controversial. This report evaluates 29 randomized trials with 18,379 patients in whom long-term (more than 1 year) outcomes were evaluated. The primary outcomes were target lesion revascularization (TLR) and the secondary end points were death, cardiac death, myocardial infarction (MI), major adverse cardiac events (MACEs), target vessel revascularization (TVR) and stent thrombosis (ST)...

Purpose Hematopoietic cell transplant patients are exposed to numerous classes of medications. Transplant practitioners must vigilantly monitor for drug interactions especially involving immunosuppressants. We report a hematopoietic cell transplant patient receiving sirolimus who developed supratherapeutic serum concentrations after initiating mirabegron. Summary A 31-year-old, 98 kg female received a second umbilical cord blood transplant four years after the first transplant for relapsed acute myeloid leukemia...

BACKGROUND: Although drug-eluting stents have dramatically reduced the rates of restenosis and target lesion revascularization, they are associated with stent thrombosis (ST), a catastrophic event likely due to delayed endothelialization and chronic inflammation caused by the polymer and the metal scaffolds. To increase the safety and efficacy of stents, polymer-free dual drug-eluting stents (DDES) have been developed. METHODS: A total 160 stents (Bare-metal stents (BMS), polymer-free probucol stents (PrES), sirolimus-eluting stents (SES) and DDES) were randomly implanted in the coronary arteries of 80 pigs...

Background: Most of the previous studies reported that tacrolimus (TAC) with sirolimus (SRL) was associated with worse post-transplant outcomes in kidney transplantation, compared with TAC with mycophenolate mofetil (MMF). These might be attributable to high-dose SRL. However, outcomes using low-dose SRL with TAC for kidney transplantation are uncertain. The aim of this study was to assess the efficacy and safety of low-dose SRL with extended-release tacrolimus (ER-TAC) versus MMF with ER-TAC...

High risk, recurrent, or refractory solid tumors in pediatric, adolescent and young adult (AYA) patients have an extremely poor prognosis despite current intensive treatment regimens. We piloted an allogeneic bone marrow transplant (alloBMT) platform using a reduced intensity conditioning (RIC) and partially HLA-mismatched (haploidentical) related donors for this population of pediatric and AYA solid tumor patients. Sixteen patients received a fludarabine, cyclophosphamide (Cy), melphalan and low dose total body irradiation (TBI) RIC haploidentical BMT (haploBMT) followed by post-transplantation cyclophosphamide (PTCy), mycophenolate mofetil (MMF) and sirolimus...

We conducted a pilot study employing extended T cell costimulation blockade (COSBL) with Abatacept along with sirolimus and post-transplantation cyclophosphamide (PTCy) in 10 patients (median age 12) with severe aplastic anemia (SAA). Nine patients engrafted in the COSBL group, compared to all 10 patients (median 14 vs 13days) treated on PTCy protocols without abatacept (CONTROL group). The incidence of acute graft-versus-host disease (GVHD) was 10.5% in the COSBL group compared to 50% in the CONTROL group (p=0...

BACKGROUND: A comparison in acute thrombogenicity between the Magmaris sirolimus-eluting bioabsorbable magnesium scaffold and the Absorb bioresorbable vascular scaffold has not been performed. This study assessed acute thrombogenicity of Magmaris compared with Absorb and the Orsiro hybrid drug-eluting stent in a porcine arteriovenous shunt model. METHODS AND RESULTS: An ex vivo porcine carotid jugular arteriovenous shunt was established and connected to SYLGARD tubing containing the Magmaris, Absorb, and Orsiro scaffolds/stents and allowed to run in the shunt for a maximum of 1 hour...

The SLENDER Integrated Delivery System (IDS™) is an 'all-in-one' fixed-wire coronary stenting device designed for direct stenting, precluding the need for conventional guidewires and predilatation balloons. It achieves ultra-low profiles (crossing profiles as low as 0.029" /0.737 mm), enabling the downsizing of catheters to facilitate TRI across wider subsets of patients. Areas covered: This paper aims to evaluate the SLENDER IDS for the treatment of coronary artery disease. Expert commentary: The system represents the first advance in coronary stent delivery since the introduction of rapid-exchange stent delivery systems more than 20 years ago and is a new...

We estimated the effect of various immunosuppressants (ISs) and metformin (M) to provide theoretical background of optimal therapeutic strategy for de novo colon cancer after liver transplantation (LT). Three colon cancer cell lines (HT29, SW620, and HCT116) were used in in vitro studies. HT29 was also used in BALB/c-nude mice animal models. Following groups were used in both in vitro and in vivo studies: sirolimus (S), tacrolimus (T), cyclosporin A (CsA), M, metformin/sirolimus (Met/S), metformin/tacrolimus (Met/T), and metformin/cyclosporin A (Met/CsA)...

A 36-year-old Caucasian woman with history of heart transplantation on sirolimus, tacrolimus and prednisone presented to the Emergency Department with abdominal pain, one day following lisinopril initiation.

Rapamycin (sirolimus) is an antiproliferative drug that has been widely used in the clinic as an immunosuppressant and a potential anticancer agent. Certain reports have indicated that rapamycin may induce male infertility through impairing sperm quality. The present study investigated the mechanism of male infertility caused by rapamycin and examined whether withdrawal of rapamycin could recover the number of sperm in rats. Male Sprague‑Dawley rats (n=100) were divided randomly into 5 groups: 3 rapamycin‑treated groups (2, 4 and 6 mg/kg) and 2 control groups [Blank and dimethyl sulfoxide (DMSO)]...

Background  Kaposiform hemangioendothelioma (KHE) is a vascular tumor frequently associated with Kasabach-Merritt phenomenon (KMP), characterized by severe thrombocytopenia and consumptive coagulopathy. Visceral involvement in KHE is rare. In our recent experience, sirolimus has shown to be an effective treatment in cutaneous KHE, becoming indeed the treatment of choice in KMP. We report a case of pancreatic KHE associated with KMP and refractory to sirolimus. Case Report  A 4-month-old infant is referred for obstructive jaundice (10 mg/dL conjugated bilirubin) secondary to vascular pancreatic tumor...
