Abstract

Abstract : Solid organ transplant (SOT) recipients are exposed to respiratory viral infection (RVI) during seasonal epidemics; however, the associated burden of disease has not been fully characterized. We describe the epidemiology and outcomes of RVI in a cohort enrolling 3294 consecutive patients undergoing SOT from May 2008 to December 2015 in Switzerland. Patient and allograft outcomes, and RVI diagnosed during routine clinical practice were prospectively collected. Median follow‐up was 3.4 years (interquartile range 1.61–5.56). Six hundred ninety‐six RVIs were diagnosed in 151/334 (45%) lung and 265/2960 (9%) non‐lung transplant recipients. Cumulative incidence was 60% (95% confidence interval [CI] 53%‐69%) in lung and 12% (95% CI 11%‐14%) in non‐lung transplant recipients. RVI led to 17.9 (95% CI 15.7–20.5) hospital admissions per 1000 patient‐years. Intensive care unit admission was required in 4% (27/691) of cases. Thirty‐day all‐cause case fatality rate was 0.9% (6/696). Using proportional hazard models we found that RVI (adjusted hazard ratio [aHR] 2.45; 95% CI 1.62–3.73), lower respiratory tract RVI (aHR 3.45; 95% CI 2.15–5.52), and influenza (aHR 3.57; 95% CI 1.75–7.26) were associated with graft failure or death. In this cohort of SOT recipients, RVI caused important morbidity and may affect long‐term outcomes, underlying the need for improved preventive strategies. Abstract : The authors report that while respiratory viral infections are common and cause significant short‐term morbidity for transplant recipients, lower respiratory tract infections and influenza are associated with an increased risk of graft failure and death, highlighting the need for improved preventive strategies.
