Bloodstream infections (BSIs) are a major cause of morbidity and mortality in transplant recipients. The aim of this study is to describe the incidence, microbiology and outcomes of BSIs in transplant recipients in Spain. The Spanish Network for Research on Infection in Transplantation (RESITRA) is formed by 16 centers with transplant program in Spain. The(More)
INTRODUCTION Expansion of donor criteria has become necessary with the increasing number of liver transplantation candidates, as aged donors who have been considered to yield marginal organs. METHODS Our database of 477 liver transplants (OLT) included 55 cases performed from donors at least 70 years old vs 422 with younger donors. We analyzed(More)
A prospective, multicentre, population-based surveillance programme for Candida bloodstream infections was implemented in five metropolitan areas of Spain to determine its incidence and the prevalence of antifungal resistance, and to identify predictors of death. Between May 2010 and April 2011, Candida isolates were centralized to a reference laboratory(More)
Eighty-four HCV/HIV-coinfected and 252-matched HCV-monoinfected liver transplant recipients were included in a prospective multicenter study. Thirty-six (43%) HCV/HIV-coinfected and 75 (30%) HCV-monoinfected patients died, with a survival rate at 5 years of 54% (95% CI, 42-64) and 71% (95% CI, 66 to 77; p = 0.008), respectively. When both groups were(More)
In this prospective study we analyzed pretransplant interferon-γ secretion by cytomegalovirus (CMV)-specific CD8+ T cells to assess its possible utility in determining the risk of CMV replication after solid organ transplantation. A total of 113 lung and kidney transplant patients were enrolled in the study but only 55 were evaluable. All CMV-seronegative(More)
BACKGROUND Urinary tract infection (UTI) is the most common infection in renal transplant patients, but it is necessary to determine the risk factors for bacterial UTI in recipients of other solid organ transplants (SOTs), as well as changes in etiology, clinical presentation, and prognosis. METHODS In total, 4388 SOT recipients were monitored in 16(More)
BACKGROUND It is necessary to clarify the incidence of and risk factors for tuberculosis (TB) among solid-organ transplant (SOT) recipients as well as changes in the chronology, clinical presentation, and prognosis of the disease. METHODS A total of 4388 SOT recipients were monitored prospectively at 16 transplant centers included in the Spanish Network(More)
Information describing the incidence and clinical characteristics of late infection (LI) in solid organ transplantation (SOT) is scarce. The aim of this study was to define the incidence, clinical characteristics and risk factors for LI (>6 months) as compared with infection in the early period (<6 months) after SOT. By the online database of the Spanish(More)
BACKGROUND Current advances in transplantation practices may influence the development of cytomegalovirus (CMV) disease after renal transplantation. METHODS From September 2003 through February 2005, 1470 renal transplant recipients (55 of whom were kidney-pancreas transplant recipients) were prospectively studied in the 16 transplant centers affiliated(More)
BACKGROUND The aim of this study was to compare the effectiveness of the ampicillin plus ceftriaxone (AC) and ampicillin plus gentamicin (AG) combinations for treating Enterococcus faecalis infective endocarditis (EFIE). METHODS An observational, nonrandomized, comparative multicenter cohort study was conducted at 17 Spanish and 1 Italian hospitals.(More)
