National transplant societies, including the American Society of Transplantation, recommend screening for latent TB prior to transplant, with treatment in the peritransplant setting to reduce the subsequent risk of TB reactivation. Though screening is traditionally conducted using laboratory-based assays, such as the QuantiFERON-TB Gold, false negatives may occur in SOT candidates due to anergy from end-stage organ dysfunction, highlighting the need for a multimodal diagnostic approach. In this case series, we describe the clinical characteristics and outcomes of 3 SOT recipients at the University of Pennsylvania with negative pretransplant QuantiFERON-TB Gold testing who subsequently developed active TB in the posttransplant setting, contributing to a growing body of knowledge regarding this challenging population. Each patient experienced a complicated clinical course that arose in part from the lack of diagnosis of TB prior to transplant. Because all had epidemiologic risk factors for TB, the findings of our study highlight the need for more individualized approaches to pretransplant TB screening. 收起
