Abstract
Lung transplantation has become an accepted treatment for end-stage pulmonary parenchymal and vascular diseases. Infections still are the most common cause of early and late morbidity and mortality in lung transplant recipients. Bacterial infections comprise approximately half of all infectious complications. Cytomegalovirus (CMV) infections and disease have become less frequent, because of prophylaxis with ganciclovir. Because CMV is also involved in the pathogenesis of obliterative bronchiolitis, the frequency of this infection may also reduce the occurrence of this main obstacle to successful lung transplantation. Invasive fungal infections remain a problem, but they have also decreased in frequency because of better control of risk factors such as CMV disease and preemptive antifungal therapy. Nonherpes respiratory viral infections have emerged as a serious problem. Their severity may be reduced by treatment with ribavirin. Meticulous postoperative surveillance, however, is still crucial for the management of lung transplant patients with respect to early detection and treatment of rejection and infection.
