OBM Transplantation (ISSN 2577-5820) is an international peer-reviewed Open Access journal published quarterly online by LIDSEN Publishing Inc., which covers all evidence-based scientific studies related to transplantation, including: transplantation procedures and the maintenance of transplanted tissues or organs; assimilation of grafted tissue and the reconstitution of removed organs or parts of organs; transplantation of heart, lung, kidney, liver, pancreatic islets and bone marrow, etc. Areas related to clinical and experimental transplantation are also of interest.

OBM Transplantation is committed to rapid review and publication, and we aim at serving the international transplant community with high accessibility as well as relevant and high quality content.

The journal publishes all types of articles in English. There is no restriction on the length of the papers. We encourage authors to be concise but present their results in as much detail as necessary, as reviewers are expected to emphasize scientific rigor and reproducibility.

Liver transplantation; survival; infection

Liver disease causing end organ failure is a growing cause of mortality worldwide. It is estimated that up to 25% of all persons have risk factors for developing liver disease including viral hepatitis, fatty liver disease and alcohol abuse. Unfortunately, for many of these individuals they will develop decompensated liver failure and in most cases the only effective therapy for this end stage disease is liver transplantation.

Fortunately, liver transplantation as a clinical undertaking has achieved high levels of success and as such is regarded as standard of care for the treatment of decompensated liver failure worldwide. But those success rates are still negatively affected by infectious complications. Currently survival rates for liver transplantation are 85-90% at one year. Infectious complications post liver transplant may account for up to 25-30% of that mortality. Thus, understanding and improving our management of infectious risk pre and post-transplant could lead to significant improvement in patient outcomes after this complex surgery.

With this in mind, we have commissioned this special issue of OBM-Transplantation to address the current state of infections and their impact on liver transplantation. We have chosen to focus on infections pre-transplant which have had significant effects on post-transplant survival such as the viral hepatitides, fungal infections, bacterial infections, and viral reactivation diseases. These compromise the vast majority of infectious risk to the liver transplant recipient. Control of viral hepatitides in the pre- and post-transplant setting has significant effects on patient survival and graft function and the emergence of new anti-virals, particularly for the treatment of Hepatitis C has radically changed the paradigms of treatment.

Fungal infections after liver transplant still represent a considerable risk for infectious morbidity and mortality to the immunosuppressed patient. Diagnosis, prophylaxis, and treatment of these infections is an ever changing field and new therapeutics have broadened the scope of effective therapy but also reflect the increasing danger posed by this class of infectious organisms.

Finally, although viral reactivation diseases such as CMV have been known to affect allograft function after liver transplant, there is still little consensus regarding their monitoring and management in the liver transplant recipient. In particular, there is renewed interest in CMV infection in transplant recipients as the immune response to the virus appears to cause graft injury versus injury from viral replication alone. Thus, achieving the right balance of decreased immunosuppression and treatment of viral replication is critical to the successful control of this and other viral reactivation diseases.

Given of importance of these topics to the field of liver transplantation, we are pleased to present this special issue of OBM-Transplantation. We believe it will provide an important reference for clinicians caring for liver transplant recipients and spur discussion of how to improve treatment modalities to limit infectious complications in this group of patients.
