Respiratory Viral Infections in Transplant and Oncology Patients

Abstract: Respiratory viral infections are a significant cause of morbidity and mortality in the immunocompromised host. In the last two decades, there has been significant advancement in the epidemiology and laboratory diagnosis of respiratory viral infections. In addition, the clinical consequences of many respiratory viruses in the immunocompetent and immunocompromised host continue to be studied. Many therapeutics have also now become available, although their efficacy in transplant recipients remains uncertain. Thi… Show more

“…6 Typically, this imbalance may lead to the development of a negative outcome by favoring both direct CMV cytotoxic effects and by the so called indirect CMV effects, which are believed to be a consequence of the complex immunomodulatory and proinflammatory events triggered by the virus. 7,8 While both heart and lung recipients are exposed to the risk of the "indirect" effects, lung transplant recipients are particularly exposed to the "direct" cytotoxic effects of CMV: bearing endothelial, mononuclear and stromal cells, lung is a peculiar latency site of CMV, which may often combine with community acquired respiratory viruses in leading to acute and chronic graft injury [9][10][11] In this article we will revise the most recent updates regarding the therapeutic strategies for preventing CMV adverse effect and treating CMV infection in heart and lung transplantation, focusing not only on the effects and usage of pharmacologic agents, but also on the potential tools for therapy customization and specific modulation of the immune system against the virus.…”

“…In particolare, le infezioni respiratorie da virus influenzali determinano il 20-30% delle morti nei bambini di età inferiore a 6 anni nei paesi in via di sviluppo, mentre risultano responsabili di un significativo aumento della spesa sanitaria nei paesi sviluppati dove le percentuali di mortalità in genere non hanno raggiunto valori di rilievo (1,4,8,11,12). Tuttavia, dati recenti dell'Health Protection Agency hanno segnalato diversi decessi associati a virus influenza A di tipo H1N1 nel Regno Unito (2, 5, 6) in soggetti appartenenti a categorie a rischio non vaccinate.…”

“…Seroresponse after 6- 4,5 . Nas últimas duas décadas, com os avanços na detecção molecular, os VRC têm sido reconhecidos de maneira crescente como causa de infecção em pacientes submetidos ao TCTH 2,6,7,8,9,10,11 . Sua incidência varia de 3,5% a 29% 10 e a mortalidade relacionada é de 2% a 18% 11, 12,13. Receptores de TCTH geralmente apresentam altas cargas de VRC nas secreções respiratórias e excreção viral prolongada.…”
