BACKGROUND The long-term outcomes of kidney transplantation are suboptimal because many patients lose their allografts or experience premature death. Cross-country comparisons of long-term outcomes of kidney transplantation may provide insight into factors contributing to premature graft failure and death. We evaluated the rates of late graft failure and(More)
HIV infection has experienced dramatic improvement in morbidity and mortality with the highly active antiretroviral therapy (HAART). This prompted a reevaluation of organ-solid transplantation as a treatment option for HIV-infected patients. Some trials in the United States have shown that one- and 2-year graft and patient survival is comparable to(More)
BACKGROUND Hepatitis C virus (HCV) infection has been associated with an increased incidence of diabetes mellitus, both in the general population and among transplant patients. METHODS To test this hypothesis, we reviewed the records of 1614 patients who had undergone renal transplant at six Spanish centres between 1992 and 1998. We established the rate(More)
Calcineurin inhibitor drugs (CNI) are the mainstay of modern immunosuppression in renal transplantation. However, they contribute significantly to the chronic loss of renal grafts and the high morbidity and mortality in this population due to their deleterious effects on the renal graft, cardiovascular profile and tumour pathology. Anti-mTOR drugs,(More)
This open, multicenter, randomized, parallel-group study evaluated the efficacy and safety of tacrolimus-based dual and triple therapy regimens. For this 3-month study (with 12-month follow up), 491 adult renal transplant patients were randomized and received either dual therapy (tacrolimus/corticosteroids; 246 patients) or triple therapy(More)
BACKGROUND Noncompliance to immunosuppressive treatment is 1 of the risk factors for kidney graft loss. The once-daily, prolonged-release tacrolimus formulation may improve treatment adherence. We sought to compare the pharmacokinetics of both tacrolimus formulations in older de novo recipients of a cadaveric renal transplant from an expanded-criteria(More)
BACKGROUND The rate of acute rejection (AR) has decreased significantly, but whether this is associated with improvement in long-term graft survival is controversial. METHODS We analyzed 1445 consecutive adult deceased donor kidney transplant recipients from 1985 to 2005, over two periods (1985-1995 vs. 1996-2005) to compare long-term graft survival. (More)
We analyzed graft half-life and attrition rates in 1045 adult deceased donor kidney transplants from 1986-2001, with follow-up to 2011, grouped in two periods (1986-95 vs. 1996-01) according to immunosuppression. The Kaplan-Meier curve showed a significant increase in graft survival during 1996-2001. The uncensored real graft half-life was 10.25 years in(More)
INTRODUCTION Proteinuria is related to a poor prognosis for graft survival. MATERIALS AND METHODS We undertook a retrospective study of renal transplant biopsies between 2006 and 2009 performed because of proteinuria. Data were collected on demographic, analytical, and histological characteristics. RESULTS The study included 49 biopsies from 65% men(More)
Suitable selection of donors is key to the success of human islet isolation and transplantation. Although several important donor-related factors have been identified previously, they needed to be confirmed in our setting. The aims of this study were: (1) to compare the characteristics of islet donors with those of pancreas donors (national transplant(More)
