Hepatitis C (HC) is a very relevant negative prognosis factor for graft and transplant recipient survival. New direct-acting antivirals (DAAs) allow us to solve this problem in an effective way. It is crucial to understand their real impact in our daily practice. We analyzed treatment results with DAA, free of interferon, in kidney transplant recipients (KTRs) from 15 Spanish hospitals (Grupo Español de Actualización en Trasplante), regarding effectiveness, tolerance, and impact on immunosuppression, renal function-proteinuria, and diabetes...

OBJECTIVE: Left ventriuclar mass (LVM) is a strong predictor of cardiovascular events. In patients with chronic kidney disease and in patients on dialysis left ventricular hypertrophy is highly prevalent. Overcoming uremia by renal transplantation might improve LVM. However, after transplantation treatment with steroids and calcineurin inhibitors increases blood pressure and therefore might counteract the positive effect of restoring renal function.We performed a metaanalysis of the available evidence from observational studies in patientts after renal tranplantation...

Complement system activation plays an important role in several renal pathologies, including antibody-mediated glomerulonephritis, ischaemia-reperfusion injury of trasplanted kidneys or renal allograft rejection. Besides these conditions, alternative pathway abnormalities are directly involved in the pathogenesis of C3 glomerulopathies and atypical haemolytic uraemic syndrome. These abnormalities may be inherited or acquired, the latter as autoantibodies directed against the various components and regulators of the alternative complement pathway...

Renal disease secondary to vasculitis associated with anti-neutrophil cytoplasmic antibodies (ANCA) can lead to chronic renal disease requiring renal replacement therapy. In these patients, kidney transplantation offers excellent long-term rates of allograft and patient survival; consequently, they can be trasplanted when the clinical disease activity has remitted. However, the risk of disease relapses in the renal allograft remains, although at lower rates due to modern immunosuppressive regimens. We describe the case of a male patient with extracapillary glomerulonephritis type III C-ANCA (+) who developed a recurrence in the renal allograft 8 years after transplantation...

Polyomaviruses BK and JC are ubiquitous viruses with high seroprevalence rates in general population. Following primary infection, polyomaviruses BK and JC persist latently in different sites, particularly in the reno-urinary tract. Reactivation from latency may occur in normal subjects with asymptomatic viruria, while it can be associated to nephropathy (PVAN) in kidney transplantat recipients. PVAN may occur in 1%-10% of renal transplant patients with loss of the transplanted organ in 30% up to 80% of the cases...

INTRODUCTION: The incidence of renal artery stenosis in the transplanted kidney (TRAS) varies between 2 and 23%, being the most frequent vascular complication following renal trasplantation. The delay in diagnosis and treatment can lead to functional graft loss. Percutaneous trasluminal angioplasty with stent (PTAS) is the treatment of choice to restore kidney perfusion. MATERIALS AND METHODS: Retrospective review of renal transplant casuistic in our institution between September 2005 and August 2009...

The number of lung transplantations that are performed in Spain continues to grow, with 235 transplant recipients 2010. Non-heart-beating donations have contributed to this upward progression. Our Lung Transplant Unit began its activity in October 2008 and during these last three years 97% of the transplant interventions performed have been successful. In order to increase the number of donations, we have developed a non-heart-beating donor program as part of the existing organs program in our hospital. In doing so, the development of a multi-organic preservation method (lung, liver and kidney), which we call «Bithermia Preservation», was necessary...

Renal transplantation is the best therapeutic choice in patients with end-stage renal disease (ESRD), with donation from living donors the alternative that offers the best medium- and long-term results. Because of the limited number of cadaver donors and the progressive increase in donor age, transplantation from living donors has become the renal replacement treatment of choice. Several studies have demonstrated that donation does not increase the donor's risk of developing ESRD in the long term. Some studies have asserted that a donor's life expectancy increases as a result of the comprehensive study and screening process they must undergo...

Anemia is prevalent in kidney transplant recipients and likely contributes to morbidity and mortality. The definition of anemia as established by the World Health Organization and subsequently adopted by the American Society of Transplantation is a hemoglobin concentration of 12 g/dL or less in women and 13 g/dL or less in men. Using this definition, the prevalence of anemia is nearly 30%. The National Survey of Post Transplant Anemia (PTA) in kidney transplant recipients in Argentina was conducted to evaluate the incidence of PTA at 1 year and its relationship to variables that influence transplantation outcome...

The National Kidney Transplant Program with cadaveric donors is based on centralized and unique waitlist, serum bank, and allocation criteria, approved by Instituto Nacional de Donación y Trasplante (INDT) in agreement with clinical teams. The median donor rates over last 3 years is 20 per million population and the median number of waitlist candidates is 450. The increased number of waiting list patients and the rapid aging of our populations demanded strategies for donor acceptance, candidate assignment, and analysis of more efficient and equitable allocation models...

Fever in an immunocompromised patient like the transplanted subject is usually due to an overt or occult infection. Clinicians must make important decisions to find the cause of fever, and also concerning the timing and adequacy of empiric antibiotic therapy. However, occasionally, fever is not due to an infectious cause. A correct identification of its causes may avoid a needlessly prolonged course of antibiotics. Herein we have reported a kidney transplant patient with a febrile syndrome, which appeared after endovascular aortoiliac stent-graft placement, that was finally attributed to a noninfectious cause like postimplantation syndrome...

INTRODUCTION: The use of mycophenolate mofetil (MMF) is limited by gastrointestinal adverse events (GI-AEs). Enteric-coated mycophenolate sodium (EC-MPS) was developed to avoid these effects. METHODS: This multicenter prospective study sought to analyze the clinical benefit of EC-MPS among 726 stable renal transplant recipients in Spain. The data collection included: doses and trough levels of mycophenolic acid (MPA) and calcineurin inhibitors (CNI), renal function, routine biochemical parameters (3-6 months preconversion, baseline, and 1, 3, 6, and 12 months of EC-MPS initiation), as well as graft and patient survivals and adverse events...
