BACKGROUND Transplant recipients in whom cutaneous squamous-cell carcinomas develop are at high risk for multiple subsequent skin cancers. Whether sirolimus is useful in the prevention of secondary skin cancer has not been assessed. METHODS In this multicenter trial, we randomly assigned transplant recipients who were taking calcineurin inhibitors and had(More)
Members of the cytokine receptor family are composed of several noncovalently linked chains with sequence and structure homologies in their extracellular domain. Receptor subfamily members share at least one component: thus the receptors for interleukin (IL) 2 and ILl5 have common ~ and 3" chains, while those for IL2, 4, 7, and 9 have a common 3' chain. The(More)
BACKGROUND Extended soft tissue defects of the face are difficult to reconstruct, and autologous tissue transfers usually lead to poor cosmetic and functional outcomes. We judged that composite tissue transplantation could be valuable in facial reconstructive surgery. METHODS We transplanted the central and lower face of a brain-dead woman onto a woman(More)
The specificity of chronic histological lesions induced by calcineurin inhibitors (CNI) is often questioned, but few studies have directly compared long-term lesions in renal-transplant patients who received this treatment and those who did not. We therefore conducted a retrospective study of 141 kidney-transplant recipients treated with (n = 48) or without(More)
Members of the cytokine receptor family are composed of several noncovalently linked chains with sequence and structure homologies in their extracellular domain. Receptor subfamily members share at least one component: thus the receptors for interleukin (IL) 2 and IL15 have common beta and gamma chains, while those for IL2, 4, 7, and 9 have a common gamma(More)
The common cytokine receptor gammac, shared by interleukin 2, 4, 7, 9, and 15 receptors, has a major role in lymphocyte proliferation and differentiation, leading, when mutated, to a genetic disease, X-linked severe combined immunodeficiency. In this study, we report that gammac is internalized and degraded in lymphoid cells. To identify gammac regions(More)
Antibody-mediated rejection (AMR) is a major cause of kidney graft loss, yet assessment of individual risk at diagnosis is impeded by the lack of a reliable prognosis assay. Here, we tested whether the capacity of anti-HLA antibodies to bind complement components allows accurate risk stratification at the time of AMR diagnosis. Among 938 kidney transplant(More)
BACKGROUND Sirolimus, a promising new immunosuppressive drug for organ transplantation, is currently associated with side effects, such as thrombocytopenia and hyperlipidemia. METHODS Eight renal transplant recipients, who developed unexplained interstitial pneumonitis during sirolimus therapy, were extensively re-screened for all causes of pneumonitis.(More)
Recurrence of idiopathic focal segmental glomerulosclerosis (FSGS) is frequent after the first kidney transplantation (KT), but a recurrence that only occurred after the second KT has never been reported. Although cyclosporine reduces proteinuria and prolongs graft survival in patients with recurrent glomerulosclerosis, the effectiveness of sirolimus for(More)
We report the case of a renal transplanted patient, in whom the detection of a unique anti HLA-DP antibody response preceded the development of chronic humoral rejection. In addition to donor-specific anti-DP alloantibodies, the patient displayed reactions against several non-donor-specific DP antigens (NDSA). Interestingly, we found that all the DP(More)
