Predicting Kidney Transplantation Outcomes from Donor and Recipient Characteristics at Time Zero: Development of a Mobile Application for Nephrologists.

(1) Background: We report on the development of a predictive tool that can estimate kidney transplant survival at time zero. (2) Methods: This was an observational, retrospective study including 5078 transplants. Death-censored graft and patient survivals were calculated.

Does the Kidney Donor Profile Index (KDPI) predict graft and patient survival in a Spanish population?

Background And Objective: The Kidney Donor Profile Index (KDPI), together with other donor and recipient variables, can optimise the organ allocation process. This study aims to check the feasibility of the KDPI for a Spanish population and its predictive ability of graft and patient survival.

Materials And Methods: Data from 2,734 kidney transplants carried out in Andalusia between January 2006 and December 2015 were studied.

Socio-sanitary profile and information for living kidney donors and recipients in three Andalusian hospitals.

Background: Information provided by health professionals to potential donors and recipients is essential for an autonomous and objective decision to make a living kidney donation.

Objectives: To determine the characteristics of the information received by living kidney donors and recipients, to find out their socio-sanitary profile, their socio-demographics, financial and labour characteristics, health and the caregiving activity of these donors and recipients.

Methods: Observational, descriptive and cross-sectional study of the population of living kidney donors and recipients from the University Hospitals Puerta del Mar (Cádiz), Virgen del Rocío (Seville), and the University Hospital Complex of Granada, between 08/04/2014 and 08/06/2015.

The DESCARTES-Nantes survey of kidney transplant recipients displaying clinical operational tolerance identifies 35 new tolerant patients and 34 almost tolerant patients.

Background: Kidney recipients maintaining a prolonged allograft survival in the absence of immunosuppressive drugs and without evidence of rejection are supposed to be exceptional. The ERA-EDTA-DESCARTES working group together with Nantes University launched a European-wide survey to identify new patients, describe them and estimate their frequency for the first time.

Methods: Seventeen coordinators distributed a questionnaire in 256 transplant centres and 28 countries in order to report as many 'operationally tolerant' patients (TOL; defined as having a serum creatinine <1.

Clinical evolution of chronic renal patients with HIV infection in replacement therapy.

Patients on renal replacement therapy (RRT) infected with the human immunodeficiency virus (HIV) are a special group with growing interest. In order to study the epidemiological data of HIV+ patients on RRT in Spain, we collected individual information from 2004-2011 (period of use of highly active antiretroviral therapy [HAART] in the Autonomous Communities of Andalusia, Aragon, Asturias, Catalonia, Valencia, Castilla la Mancha, Castilla León, Galicia, Madrid, La Rioja and the Basque Country, comprising 85% of the Spanish population. A total of 271 incident and 209 prevalent patients were analysed.

Progression of urinary protein excretion after kidney transplantation: A marker for poor long-term prognosis.

Introduction: Post-transplantation proteinuria is a risk factor for graft failure. A progressive decline in renal graft function is a predictor for mortality in kidney transplant patients.

Objectives: To assess the development and the progression of urinary protein excretion (UPE) in the first year post-transplant in recipients of kidney transplants and its effect on patient and graft outcomes.

Harmful effects of viral replication in seropositive hepatitis C virus renal transplant recipients.

Background: Seropositivity for hepatitis C virus (HCV) predicts lower patient and graft survival after renal transplantation (RT). However, the influence of viral replication at transplantation on long-term outcome remains to be determined.

Methods: This was a retrospective study conducted in four Spanish hospitals, from 1997 to 2006.

Clinical relevance of anti-HLA donor-specific antibodies detected by Luminex assay in the development of rejection after renal transplantation.

Background: The role of anti-human leukocyte antigen (HLA) donor-specific antibodies (DSA) detected by Luminex in the development of rejection is not fully understood.

Methods: A study including 369 patients who received transplants from deceased donors with a negative complement-dependent cytotoxicity crossmatch (XM) was performed. From the total of patients, 151 underwent a renal biopsy because of renal dysfunction, whereas the 218 remaining showed a stable renal function, and no rejection was assumed.

Late evolution of kidney transplants in elderly donors and recipients receiving initial immunosuppressant treatment with daclizumab, mycophenolate mofetil, and delayed introduction of tacrolimus.

Background: Organ transplants in elderly recipients have increased over the past few years. This situation poses specific problems both in terms of organs and recipients; therefore, immunosuppressant regimens must be adapted accordingly. A previous study demonstrated good initial results in kidney transplant cases in which older donors and recipients (average ages of 64.

Clinical relevance of HLA donor-specific antibodies detected by single antigen assay in kidney transplantation.

Background: Clinical relevance of donor-specific antibodies (DSAs) detected by a single antigen Luminex virtual crossmatch in pre-transplant serum samples from patients with a negative cytotoxicity-dependent complement crossmatch is controversial. The aim of this study was to analyse the influence of a pre-transplant positive virtual crossmatch in the outcome of kidney transplantation.

Methods: A total of 892 patients who received a graft from deceased donors after a negative cytotoxicity crossmatch were included.

[Assessment and selection of kidney living donors].

Donor protection should always be taken account during the selection and assessment of a living donor. On these terms, the evaluation of a potential donor must include these issues: 1) The donor act is altruistic, consciousness and out of coercion; 2) Life expectancy and quality of life of the recipient will improve after the living donor kidney transplantation; 3) The donor has normal renal function and the potential risk of developing nephropathy in the long term follow up is scarce (familiar nephropathies and other processes that may increase the potential risk for renal disease in the future, like severe hypertension, diabetes, etc must be ruled out). The glomerular filtrate should meet criteria for the normal function corresponding to age furthermore the absence of proteinuria and urine smear is normal; 4) The screening in the donor should contemplate those clinical situations or diseases non related to the kidney function but might elevate the surgical and/or anesthesia risk besides disease transmission to the recipient (as neoplasia or infections); 5) The surgical act is possible without technical difficulties and always performed after a negative result of the crossmatch between donor and recipient.
