Apoptotic leukocytes are endowed with immunomodulatory properties that can be used to enhance hematopoietic engraftment and prevent graft-versus-host disease (GvHD). This apoptotic cell-induced tolerogenic effect is mediated by host macrophages and not recipient dendritic cells or donor phagocytes present in the bone marrow graft as evidenced by selective(More)
BACKGROUND Insulin resistance with compensatory hyperinsulinaemia has been reported in adult polycystic kidney disease (APKD) patients. Diabetes mellitus is a common complication following transplantation and previous studies have demonstrated that inadequate insulin secretion was a prerequisite for the development of post-transplant diabetes mellitus(More)
Flow-PRA is a flow cytometric method for both anti-HLA class I and class II antibody (Ab) detection. We evaluated this technique for Ab screening in patients awaiting kidney transplantation. After having established a rigorous threshold for positivity, a three-dilution difference in sensitivity between Flow-PRA and complement-dependent cytotoxicity (CDC)(More)
A G-->C polymorphism has been identified in the human cyclooxygenase-2 (COX-2) gene promoter at position -765 with C allele leading to a decreased promoter activity with low prostaglandin E2 (PGE2) production. PGE2 has strong immunomodulatory properties that could influence graft survival. We studied the association between this polymorphism and allograft(More)
BACKGROUND The clinical and immunological relevance of a positive B-cell flow-cytometry (B-FCXM) crossmatch in renal transplantation is still controversial. METHODS We retrospectively analysed 145 consecutive cadaveric renal transplantations performed from May 1991 to September 1995 in our institution. All grafts were transplanted following a negative IgG(More)
BACKGROUND Renal transplant recipients are at increased risk of developing skin cancer. It remains difficult to establish the actual influence of overimmunosuppression in the development of skin cancers. We investigated whether lymphocyte subset count may predict the risk of developing skin cancer in long-term renal transplant recipients. METHODS One(More)
Few data are available about the muscle status in renal transplant recipients. Moreover, the list of myotoxic drugs is growing longer and some of them are likely to be prescribed in renal transplant patients. These conditions may act as confounding factors in case reports of both cyclosporin and colchicine myopathies. Moreover no study has evaluated the(More)
BACKGROUND There is a great concern over cyclosporine (CsA) nephrotoxicity in renal transplant recipients, and the effects of conversion from CsA to azathioprine (AZA) remain controversial. Large studies have demonstrated that mycophenolate mofetil (MMF), the morpholinoethyl ester of mycophenolic acid, is superior to AZA as a posttransplant(More)
Renal transplant recipients have disproportionately high rates of arteriosclerotic outcomes, and recent studies provided controlled evidence that clinically stable renal transplant recipients have an excess prevalence of hyperhomocysteinemia. Few studies suggest that hyperhomocysteinemia may be a cardiovascular risk factor in renal transplant recipients. In(More)
