Résumé : Background: There is no consensus on the optimal management of immunosuppression during bacterial infections among solid organ transplant recipients. Methods: A multicenter, cross-sectional survey, of high-volume kidney and liver transplant centers across US and Europe. Structured questionnaires including six multiple-choice questions concerning the management of immunosuppression during infection were distributed among 381 centers. Results: A total of 124 (33%) centers fully completed the questionnaire: 67 liver, 57 kidney centers. Participating centers reported heterogenous approaches to immunosuppression management for all types of immunosuppressive drugs. Notably, kidney centers reported similar frequencies of either discontinuation (19%), continuation (19%), or dose reduction (17.5%) of antimetabolites; discontinuation only for life-threatening infection (17.5%) or case by case decisions (27%). Calcineurin inhibitors (CNI) management was heterogenous mostly among liver centers, with 8% discontinuing the CNI, 18% continuing, and 22% reducing dose. Heterogenous approaches to management of steroids and inhibitors of the mammalian target of rapamycin were also demonstrated. Conclusions: Immunosuppression management during bacterial infection is heterogenous in US and European centers. Immunosupression reduction (ISR) during infection is a common practice, though supported by limited evidence. Demonstrating high heterogeneity in the approach to ISR, together with the equivocal results of clinical studies, support consideration of an interventional clinical trial.
