title: [Effects of viral infection on transplant recipients].
abstract: Viral infection remains an important cause of morbidity and mortality in transplant recipients. The risk of viral infection in these patients depends on several factors, such as the type of organ transplanted, the intensity of immunosuppression, and the recipient's susceptibility. In additional to direct effects, viral infection cause indirect effects, including greater risk of replication of other viruses, graft rejection, opportunistic infections and other specific entities for each type of transplant. These indirect effects result from the immunomodulatory activity of some viruses, such as cytomegalovirus and human herpes virus-6. For the most part, quantitative molecular tests have replaced serologic testing and in vitro culture for diagnosing infection. This approach is particularly prominent for cytomegalovirus, Epstein-Barr virus, hepatitis B virus, and hepatitis C virus. Despite these diagnostic advances, the development of specific antiviral agents and effective antiviral vaccines is limited. Thus, prophylactic strategies are still essential in transplant recipients.
