Liver dysfunction is an important cause of morbidity and mortality after orthotopic liver transplantation (OLT). The Molecular Adsorbent Recirculating System (MARS) is an albumin-based dialysis system designed to enhance the excretory function of a failing liver. MARS has been successfully used in patients affected by advanced liver disease and presenting with severe cholestasis. ⋯ The patients with intractable pruritus showed significant improvement of this symptom after MARS therapy. Thus, MARS is a safe, therapeutic option for the treatment of liver dysfunction after OLT. Further studies are necessary to confirm whether this treatment is able to improve both graft and patient survival.

Few biomarkers exist to monitor chronic kidney disease (CKD). Neutrophil gelatinase-associated lipocalin (NGAL), a member of lipocalin family, has recently been proven useful to quantitate CKD. The aim of the study was to assess whether NGAL could represent a novel, sensitive marker of kidney function in adult patients with CKD and in kidney transplant recipients. ⋯ NGAL should be investigated as a potential early, sensitive marker of kidney impairment/injury, which might provide an additional accurate measure of kidney impairment in CKD and among transplant recipients, particularly at advanced stages.

Determination of cardiac output (CO) is crucial for perioperative monitoring of orthotopic liver transplant (OLT) recipients. A pulmonary artery catheter (PAC) has always been considered the "gold standard" of hemodynamic monitoring. The aim of this study was to evaluate the suitability of a transesophageal echo-Doppler device (ED) as a minimally invasive device to measure CO in OLT. ⋯ In patients with MELD score <15, the bias was 0.12 +/- 0.55. The ED results were not interchangeable with PAC, because of the large limits of agreement. However, in cirrhotic patients with MELD scores <15, the precision of the new method was similar to that of PAC; therefore, in this subset of patients, it may represent a reliable alternative to PAC.

University of Wisconsin (UW) and histidine-tryptophan-ketoglutarate (HTK) solutions are the 2 most commonly used liver preservation solutions. The aim of this study was to compare cardiovascular stability, acid-base status, and potassium concentrations between patients who received grafts preserved in either UW or HTK solution in orthotopic liver transplantation (OLT). ⋯ The incidence of PRS was greater using HTK compared with UW solution during the reperfusion period. Therefore, careful hemodynamic management is advised when using HTK solution.

Herein we have reported our experience concerning the usefulness of extracorporeal membrane oxygenation (ECMO) in heart transplant patients. ⋯ Rapid operating room or bedside placement of ECMO allowed stabilization of hemodynamics with potential myocardial recovery in patients with cardiac graft failure.
