title: Immunosuppression in renal transplantation: viral diseases and chronic allograft nephropathy.
abstract: Chronic allograft dysfunction after renal transplantation can be ascribed to different causes, among which are viral infections. The aim of this work was to show the various ways by which different kinds of viruses affect transplant structure and function. Polyoma virus is an example of viruses directly affecting the kidney because of a specific tropism to the uroepitelial cells. Cytomegalovirus (CMV) has been chosen both because of the frequency of this infection and because CMV (as other viruses) can produce transplant vascular sclerosis. Finally, we describe hepatitis C virus (HCV) because of its capacity to induce renal lesions independently from chronic allograft nephropathy. Indeed HCV is likely to determine immunologically mediated nephritis in the transplanted kidney as well in the native one.
