Using expanded criteria donor (ECD) organs is 1 strategy to make more organs available for transplant. To reduce the number of posttransplant complications and failures, there is a need to create a comprehensive system of evaluation before transplantation, especially for kidneys harvested from ECD. The aim of this study was to assess the results of kidneys procured from ECD seeking to discover the most useful factors for kidney evaluation before transplantation. ⋯ There was no significant difference in patient survival between recipients of kidneys harvested from expanded versus standard criteria donors. ECD kidneys displayed lower graft survival rates. There was no significant difference in the incidence of delayed graft function between recipients of kidneys harvested from expanded versus standard criteria donors. Pretransplant evaluation of ECD kidneys should include 3 variables: donor parameters, histologic findings, and machine perfusion parameters.

Kidney injury represents a major clinical problem in orthotopic heart transplant (OHT) patients which seriously increases the mortality rate. The aim of this work was to evaluate the utility of a new kidney damage marker-neutrophil gelatinase-associated lipocalin (NGAL)-and its correlations with cystatin C, creatinine, and glomerular filtration rate (GFR) among patients after heart or lung transplantation. ⋯ Plasma NGAL was not a specific biomarker for monitoring chronic renal disorders. We did not exclude other pathologies that might contribute to increased serum NGAL levels.

Spain has been showing the highest rate of deceased donor organ recovery in the world for a whole country, namely, 33-35 donors per million population (pmp) during the last years. This activity is attributed to the so-called Spanish Model of organ donation, an integrated approach to improve organ donation since the start of the Organización Nacional de Trasplantes (ONT) in 1989. However, in 2007 there were 7/17 regions with >40 donors pmp and a marked regional variability. Thus, ONT has set a large-scale, comprehensive strategy to achieve a substantial improvement in donation and transplantation in Spain in the coming years: The 40 Donors pmp Plan. ⋯ Detection and management of brain-dead donors, with 4 specific subareas: access to intensive care units, new forms of hospital management, foreigners and ethnic minorities, and evaluation/maintenance of thoracic organ donors. Expanded criteria donors, with 3 subareas: aging, donors with positive tests to certain viral serologies, and donors with rare diseases. Special surgical techniques. Donation after cardiac death.

The knowledge of brain death (BD) epidemiology and the acute brain injury (ABI) progression profile are relevant to improve public health programs, organ procurement strategies, as well as intensive care unit (ICU) protocols aiming to increase the detection of potential donors. The aim of this study was to analyze the BD epidemiology and the ABI progression profile among subjects admitted to ICUs with a Glasgow Coma Score (GCS) < or = 8. ⋯ This study showed a 200% increment of detected BD and 150% of real donors, although these results are still below the international figures. GCS follow-up appeared to be a good tool to predict the BD outcome. The follow-up of patients with ABI allowed us to improve our BD detection strategy.

Because lung transplantation is the only effective therapy for terminal respiratory failure, the demand for donor lungs has increased steadily. However, the number of donors has remained fairly constant over the years, which results in an increasing duration of waiting for lung transplantation. To overcome the lack of organs, various strategies have been developed by transplant centers including use of marginal donors. ⋯ We were able to improve gas exchange sufficiently that as many as two-thirds of the lungs were suitable for transplantation. During the protocol, no complications were reported, and no patient became hemodynamically unstable, precluding organ procurement. We believe that optimization of multiorgan donor management with simple interventions may improve oxygenation, reducing the number of inadequate donor lungs and increasing the overall donor pool and organ availability.
