Cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpesvirus-6 (HHV-6) cause symptomatic diseases in liver transplant recipients. The loads of these viruses, the associations between viral DNAemia, serologic status, and acute rejection reactions were investigated in a group of 17 juvenile and 17 adult recipients of living donor liver transplantation (LDLT) for a median of 8 weeks posttransplantation. At least 1 plasma sample from 15/34 (44.1%) patients was positive for CMV DNA. ⋯ Serologic status seemed to be an important factor for all 3 viral infections. The rate of acute cellular rejection was not significantly higher in the CMV-, EBV-, or HHV-6-positive groups. Simultaneous monitoring for 3 herpesviruses revealed the impact of these viruses on LDLT recipients.

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.

Hepatopulmonary Syndrome (HPS) is a triad of liver disease, intrapulmonary vascular dilatation (IPVD), and arterial deoxygenation. Orthotopic liver transplantation (OLT) constitutes the only effective treatment; however, adverse outcomes have been reported. The aim of this study was to evaluate the early morbidity and short- and long-term survival after OLT for patients with and without HPS. ⋯ There were no significant differences between HPS and control groups regarding short- (68% vs 77%; P = .27) and long-term survival (60% vs 64%; P = .67) as well as among patients with mild, moderate, severe, or very severe HPS and the control group (P = .53). Also, intensive care unit (ICU) stay (7.0 vs 5.5; P = .41), duration of mechanical ventilation (38.0 vs 27.5; P = .43), reintubation rate (32.0% vs 23.5%; P = .45), and early postoperative complications (P = .72) were not different. In conclusion, there were no significant differences regarding the outcomes of OLT for patients with versus without HPS related to early morbidity or short- and long-term survival.

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.

Patients with high-relapse-risk lymphomas or those relapsing after initial therapy have a limited probability of cure with conventional treatment. There is recent inconclusive evidence that, in such cases, intensification or salvage treatment with high-dose chemotherapy followed by hematopoietic stem cell transplantation (HSCT) increases the response rate and may improve survival. Nevertheless, published data on long-term follow-up of high-risk lymphoma patients treated with HSCT are scarce. ⋯ The main etiologies were graft-versus-host disease and infection in the allogeneic setting, and infection in the autologous setting. The probability of long-term (12-year) overall survival was 71%, higher than that described for high-relapse-risk lymphoma patients treated without HSCT and significantly better (P < .05) for patients who received the transplant in 1CR (89%) than in AS (65%). Finally, the probability of long-term survival was significantly better for patients treated with HSCT during the period from 2000-2007 (85%) compared with the period from 1989-1999 (72%).
