BACKGROUND Currently there is no effective treatment available to retard cyst growth and to prevent the progression to end-stage renal failure in patients with autosomal dominant polycystic kidney disease (ADPKD). Evidence has recently been obtained from animal experiments that activation of the mammalian target of rapamycin (mTOR) signaling pathway plays a crucial role in cyst growth and renal...
OBJECTIVE To examine whether polymer based coronary stents eluting sirolimus or paclitaxel are equally effective in patients with and without diabetes. METHODS Systematic review and meta-analysis by indirect comparison of randomised controlled trials comparing stents eluting sirolimus or paclitaxel with conventional bare metal stents. The overall study population and patients with and without...
New-onset diabetes (NOD) is associated with transplant failure. A few single-center studies have suggested that sirolimus is associated with NOD, but this is not well established. With the use of data from the United States Renal Data System, this study evaluated the association between sirolimus use at the time of transplantation and NOD among 20,124 adult recipients of a first kidney transpla...
This report summarizes phase 1 studies that evaluated pharmacokinetic interactions between the novel triazole antifungal agent isavuconazole and the immunosuppressants cyclosporine, mycophenolic acid, prednisolone, sirolimus, and tacrolimus in healthy adults. Healthy subjects received single oral doses of cyclosporine (300 mg; n = 24), mycophenolate mofetil (1000 mg; n = 24), prednisone (20 mg;...
BACKGROUND The use of the immunosuppressant sirolimus in kidney transplantation has been made problematic by the frequent occurrence of various side effects, including paradoxical inflammatory manifestations, the pathophysiology of which has remained elusive. METHODS 30 kidney transplant recipients that required a switch from calcineurin inhibitor to sirolimus-based immunosuppression, were pr...
BK polyomavirus (BKPyV) replication causes nephropathy and premature kidney transplant failure. Insufficient BKPyV-specific T cell control is regarded as a key mechanism, but direct effects of immunosuppressive drugs on BKPyV replication might play an additional role. We compared the effects of mammalian target of rapamycin (mTOR)- and calcineurin-inhibitors on BKPyV replication in primary huma...
BACKGROUND Stent implantation for obstructive femoropopliteal artery disease has been associated with poor long-term outcomes. This study evaluated the effectiveness of shape memory alloy recoverable technology (SMART) nitinol self-expanding stents coated with a polymer impregnated with sirolimus (rapamycin) versus uncoated SMART Stents in superficial femoral artery obstructions. METHODS AND ...
OBJECTIVES The aim of this study was to examine the 5-year clinical safety and efficacy outcomes in patients enrolled in the SIRIUS (Sirolimus-Eluting Stent in De-Novo Native Coronary Lesions) trial. BACKGROUND The SIRIUS trial was a double-blinded randomized study that demonstrated that sirolimus-eluting stents (SES) significantly improved angiographic results (at 8 months) and clinical outc...
Perivascular epithelioid cell tumors (PEComas) are rare soft-tissue tumors with an extremely heterogeneous clinical behavior. They may arise in different organs and may behave indolently or sometimes metastasize with different grades of biological aggressiveness. We report the case of a young woman with a primary inoperable PEComa of the liver with malignant histological features. Since the mTO...
Percutaneous invasion of coronary arteries began with Andreas Gruentzig, who performed the first human percutaneous transluminal coronary angioplasty (PTCA). Stents, which overcame many of the limitations encountered with PTCA alone, were the next big milestone in the field of interventional cardiology. However, the incidence of restenosis even with stents remained high, at 20–40%. Over time, a...
