Calcineurin inhibitors exacerbate ischemic injury in transplanted kidneys, but it is not known if sirolimus protects or exacerbates the transplanted kidney from ischemic injury. We determined the effects of sirolimus alone or in combination with cyclosporin A (CsA) on oxygenated and hypoxic/reoxygenated rat proximal tubules in the following in vitro groups containing 6-9 rats per group: sirolim...
PURPOSE We hypothesized that lymphoid-selective host conditioning and subsequent adoptive transfer of sirolimus-resistant allogeneic T cells (T-Rapa), when combined with high-dose sirolimus drug therapy in vivo, would safely achieve antitumor effects while avoiding GVHD. EXPERIMENTAL DESIGN Patients (n = 10) with metastatic renal cell carcinoma (RCC) were accrued because this disease is relat...
BACKGROUND We hypothesized that the addition of sirolimus to standard horse antithymocyte globulin (h-ATG) and cyclosporine (CsA) would improve response rates in severe aplastic anemia, due to its complementary and synergistic properties to cyclosporine A. DESIGN AND METHODS To test this hypothesis, we conducted a prospective randomized study comparing hATG/CsA/sirolimus to standard h-ATG/CsA...
BACKGROUND Sirolimus-eluting stents have been developed to prevent restenosis in the treatment of coronary artery disease. We investigated the risk of restenosis with use of sirolimus-eluting stents compared with bare-metal stents to assess possible differences. METHODS We enrolled 352 patients in whom one coronary artery required treatment, with diameter 2.5-3.0 mm and lesion length 15-32 mm...
Background: Persistence of left ventricular hypertrophy (LVH) in renal transplant recipients is associated with unfavorable outcomes. Calcineurin-inhibitor (CNI) nephrotoxicity is a major cause of morbidity and mortality after kidney transplantation. In this study we compared sirolimus (SRL) with calcineurin-inhibitor as primary immunosuppressants for the attenuation of left ventricular hypertr...
Background Sirolimus is a non-calcineurin immunosuppressant commonly used in patients with organ transplantation to prevent rejection. While various inflammatory syndromes have been described post-sirolimus use, it uncommon arthritis sirolimus 1 . We present patient who developed significant joint inflammation following use. Results Our 39 year old gentleman had heart transplant 1992 dilated ca...
BACKGROUND In autosomal dominant polycystic kidney disease (ADPKD), aberrant activation of the mammalian target of rapamycin (mTOR) pathway is associated with progressive kidney enlargement. The drug sirolimus suppresses mTOR signaling. METHODS In this 18-month, open-label, randomized, controlled trial, we sought to determine whether sirolimus halts the growth in kidney volume among patients ...
BACKGROUND The Orsiro Hybrid sirolimus-eluting stent is a newly developed third-generation drug-eluting stent, featuring a unique dual-polymer mix. An active bioabsorbable polymer delivers the anti-proliferative drug, sirolimus, via controlled release, while a passive biocompatible polymeric coating shields the metallic strut from surrounding tissue, preventing interaction. To date, the Orsiro ...
BACKGROUND There is evidence suggesting that sirolimus, in combination with tacrolimus, is active in the prevention of graft-versus-host disease. Sirolimus-based immune suppression may suppress alloreactive T cells, while sparing the survival and function of regulatory T cells. DESIGN AND METHODS We conducted a randomized trial to compare the impact of sirolimus/tacrolimus against that of met...
Treatment options are limited for orthotopic liver transplant (OLT) recipients suffering from chronic rejection (CR). We performed a retrospective review of OLT recipients diagnosed with CR and treated with sirolimus. The medical records of all OLT recipients treated with sirolimus between October, 1998 and October, 2000 were retrospectively reviewed. The diagnosis of CR was made by both clinic...
