Kidney transplantation is the favored method to treat end-stage renal disease. Some recipients develop severe diseases requiring admission to an intensive care unit (ICU). Acute kidney injury (AKI) is a common complication among critically ill patients but few data are available among renal transplant recipients. ⋯ Mortality rate at 3 months after the ICU stay was 25.3%. Among the patients who survived, 40 (68%) recovered to their baseline renal function at 3 months, most of them being classified as no AKI during the ICU stay. We have herein reported the evolution of renal function among kidney graft recipients after an ICU stay.

Despite the high rate of kidney transplantation in Spain, a disparity still exists between the numbers of donors and waiting-list patients. Donors after circulatory death (DCD) have been propagated as a promising approach to reduce the donor kidney shortage. In Europe most of the countries use controlled DCD, but in Spain, mainly uncontrolled DCD are harvested and until 2010 at only four institutions. ⋯ There were no cases of primary nonfunction, but delayed graft function was present in 85% of recipients. Despite this impairment, about 75% of patients reached a serum creatinine below 2 mg/dL in the second month, with 1-year graft and patient survivals of 85% and 100%. Although, our preliminary results with a not very long follow-up and small number of patients suggested that utilization of DCD should be expanded because this type of donor increases the number of cases and opportunities of end-stage renal disease patients to reduce the waiting times for transplantation.

Orthotopic liver transplantation (OLT) (LTx) using donation after circulatory death (DCD) donors is increasingly performed, but still considered to risk of poorer outcomes compared with standard donations after brain death (DBD)-OLT. Therefore we reviewed our results of DCD-OLT. ⋯ Despite substantial ischemic injury (high peak AST and biliary strictures) short- and long-term survival after DCD-OLT was comparable to DBD-OLT. Rapid donor surgery, careful donor and recipient selection, as well as short warm and cold ischemia times are key factors to optimize outcomes after DCD-OLT. However, strategies to reduce biliary complications remain warranted.

Renal transplantation represents the main treatment for end-stage renal disease. The goal of this study was to evaluate the course and outcome of renal transplant recipients admitted to the intensive care unit (ICU) and to analyze factors determining prognosis and mortality. ⋯ The mortality rate was higher than that of the general ICU population (42.6% vs 30%). The main reason for ICU admission of renal transplant recipients was sepsis.

Pulmonary capillary wedge pressure (PCWP) can be estimated from transmitral or color M-mode Doppler flow propagation velocities. However, it has been recommended to not use these indices in heart transplant recipients. Our aim was to compare the accuracy of color M-mode, Doppler, and Doppler tissue imaging (DTI)-derived indices to predict PCWP in heart transplant recipients. ⋯ Compared with other indirect Doppler indices, E/Vp showed the best correlation to predict PCWP in heart transplant recipients. Despite previous recommendations, PCWP can be accurately estimated from color M-mode indices, giving useful information and avoiding the risks of invasive measurements.
