Lung transplantation (LT) is the only effective form of therapy for cystic fibrosis (CF) associated with end-stage pulmonary failure. In Italy, the management of CF is regulated by national law, which has instituted regional centers for care and follow-up of all CF patients. LT has been performed since 1992 in only nine LT certified centers. ⋯ The most frequent cause of death is bronchiolitis obliterans syndrome (BOS). Our nationwide database indicates the excellent results obtained by LT in FC. Still, mortality on the waiting list remains a challenge and long-term outcome is limited by BOS.

Lung transplantation recipients are at high risk for herpesvirus infections. We evaluated the effect of combined cytomegalovirus (CMV) prophylaxis on CMV pneumonia, acute rejection episodes (ARE), lymphocytic bronchitis/bronchiolitis (LB), and obliterans bronchiolitis (OB) diagnosed in 180 transbronchial biopsies (TBB) of lung transplant recipients. At our center, 25 patients (control group; 1999-2002) received acyclovir for 12 months and 21 recipients (study group; 2003-2007) received combined CMV prophylaxis consisting of CMV-IG (Cytotect Biotest) for 12 months and ganciclovir or valganciclovir from postoperative day 21 for 3 weeks. ⋯ Logistic regression analysis showed a relationship between prophylaxis and a reduced prevalence of ARE (odds ratio [OR] 3.25, confidence interval [CI] 1.12-9.40; P= .03). Finally, in the study group, BAL EBV-DNA positivity and EBV-CMV coinfections were low (6% and 0%, respectively) compared with other herpesviruses and with the literature. Our data suggested the efficacy of combined CMV prophylaxis to prevent ARE and LB, 2 risk factors for chronic rejection, and a possible role to reduce the trend toward CMV pneumonia and EBV infections.

Case Reports
Activated recombinant protein C in septic shock early after liver transplantation: a case report.
Severe infectious diseases after liver transplant are associated with high risk of multiorgan failure and mortality. Septic shock is difficult to manage in this setting since it is often unresponsive to conventional aggressive therapy. ⋯ Herein we have reported on a patient who was given drotrecogin alfa 15 days following liver transplant for acute septic shock originating from a nosocomially acquired pneumonia. Recombinant activated drotrecogin alfa, associated with conventional aggressive treatment, was efficacious to revert the life-threatening "slippery slope" of vasoplegia and uncontrolled diffuse inflammation.

Hemophilia B is a congenital recessive disorder caused by deficiency of coagulation factor IX (FIX). Surgical procedures can be performed in patients with hemophilia using high-purity and/or recombinant FIX, which has been shown to be safe and effective in surgical hemostasis. Liver transplantation is the only potentially curative treatment available for these patients, providing a long-term phenotypic cure for hemophilia. ⋯ It has been demonstrated to be a useful tool for real-time analysis of clot formation using a whole-blood assay format. Further, it accurately illustrates the clinical effects of procoagulant or anticoagulant interventions. In this article, we have described the usefulness of thromboelastography to monitor the ability of high-purity FIX supplementation to restore a normal coagulation state and to guide the perioperative administration of blood products in a successful orthotopic liver transplantation in a hemophilic patient with deficiencies of factors IX and X, presenting with hepatitis C virus-related cirrhosis and hepatocellular carcinoma.

Evaluation of research products released during activities that have received public funds should be a mandatory practice. In this study, we evaluated the research products released during the research program "Innovative Strategies to Expand Cadaveric Donor Pool for Liver Transplantation" (SITF Project), funded by the Italian Ministry of Health. The SITF Project prefigured the participation of Italian transplantation centers with more advanced experience in the field of liver transplantation. ⋯ Spearman's rank test found a weak negative correlation between journal IF and number of published articles (r= -.2919; P= .413). Although the OU involved in the coordination of the SITF Project released a relatively high number of articles (n=8; IF, 0.923+/-0.352), several other OUs obtained better results for number of articles (9-11) and/or IF (3.071+/-2.248 or 2.959+/-1.779). In projects that benefit from public funds, the potential negative impact of coordination activities to scientific production should be adequately considered.
