We report a case of a 65-year-old gentleman with a history of end stage renal disease who underwent a successful cadaveric donor kidney transplant four years ago. He subsequently developed BK virus nephropathy related to chronic immunosuppressant therapy. Three years later, misfortune struck again, and he developed adenocarcinoma of the bladder.
BK polyoma viral infection occurs as an asymptomatic infection in a high proportion of normal hosts without obvious sequelae. In the kidney transplant population, the virus is reactivated because of reduced immunity and, if not appropriately managed, can lead to BK viral nephropathy, which has emerged as a common cause of acute kidney injury and progressive chronic kidney disease in renal trans...
Polyomavirus BK is a significant pathogen in transplant recipients, but no effective antiviral therapy is available. We show that cidofovir can inhibit BK virus replication in vitro. Esterification of cidofovir with hexadecyloxypropyl, octadecyloxyethyl, and oleyloxyethyl groups results in up to a 3-log lowering of the 50% effective concentration and an increased selectivity index.
BACKGROUND BK polyomavirus-associated nephropathy is an important cause of post-transplantation renal failure. We present two cases of BK polyomavirus-associated nephropathy who were submitted to contrasting strategies of clinical follow-up to BK polyomavirus reactivation, but progressed to a similar final outcome. CASE PRESENTATION Case 1 is a 37-year-old white man whose graft had never pres...
Polyomavirus BK is an important pathogen in transplant recipients with no effective therapy. This study demonstrates that alkoxyalkyl esters of (S)-9-(3-hydroxy-2-phosphonylmethoxypropyl)adenine and fatty acid derivatives of 9-[2-(phosphonomethyoxy)ethyl]adenine (P393 and P405) are potent and selective inhibitors of BK virus replication in vitro, with a 50% effective concentration in the microm...
Sindbis virus (SINV) induces inflammatory and vasoactive responses that are associated with rash and arthritis in human infections. The mechanisms underlying infection-associated microvasculopathy are still unknown. We investigated whether endothelial cells infected by SINV are differentially responsive to bradykinin (BK), a potent inducer of inflammatory edema in a broad range of infectious di...
