T cell–mediated response to SARS‐CoV‐2 in liver transplant recipients with prior COVID‐19
2021
Abstract Whether immunosuppression impairs severe acute respiratory syndrome coronavirus 2‐specific T‐cell‐mediated immunity (SARS‐CoV‐2‐CMI) after liver transplantation (LT) remains unknown. We included 31 LT recipients in whom SARS‐CoV‐2‐CMI was assessed by intracellular cytokine staining (ICS) and interferon (IFN)‐γ FluoroSpot assay after a median of 103 days from COVID‐19 diagnosis. Serum SARS‐CoV‐2 IgG antibodies were measured by ELISA. A control group of non‐transplant immunocompetent patients were matched (1:1 ratio) by age and time from diagnosis. Post‐transplant SARS‐CoV‐2‐CMI was detected by ICS in 90.3% (28/31) of recipients, with higher proportions for IFN‐γ‐producing CD4+ than …
Cytomegalovirus infection management in solid organ transplant recipients across European centers in the time of molecular diagnostics: An ESGICH sur…
2017
Background Scant information is available about how transplant centers are managing their use of quantitative molecular testing (QNAT) assays for active cytomegalovirus (CMV) infection monitoring in solid organ transplant (SOT) recipients. The current study was aimed at gathering information on current practices in the management of CMV infection across European centers in the era of molecular testing assays. Methods A questionnaire-based cross-sectional survey study was conducted by the European Study Group of Infections in Immunocompromised Hosts (ESGICH) of the Society of Clinical Microbiology and Infectious Diseases (ESCMID). The invitation and a weekly reminder with a personal link to …
