Preemptive therapy (PET) and letermovir prophylaxis are effective in preventing cytomegalovirus (CMV) disease within the first 100 days after allogeneic hematopoietic cell transplantation (HCT) but associated with late-onset CMV disease. We retrospectively examined clinical manifestations, risk factors, prevention algorithm, outcome of late seropositive day survivors transplanted between 2001-2017 (PET cohort) 2018-2021 (letermovir cohort). There were 203 episodes among 2469 survivors,...

Clinically meaningful endpoints for respiratory syncytial virus (RSV) treatment trials are lacking hematopoietic cell transplant (HCT) recipients. We evaluated supplemental oxygen use among HCT recipients with RSV infection.Subjects were grouped according to the presence of upper tract infection (URTI) without lower (LRTI), URTI progressing LRTI, and LRTI at presentation. was defined as a positive sample or radiographic abnormality (defined proven probable respectively) (possible LRTI)....

Late cytomegalovirus (CMV) disease occurs in about 6% of patients (R+ or D+/R-) who survive the first three months after HCT. We have previously identified steroid treatment day 100 and CMV viremia before as risk factors for late disease. Little is known, however, epidemiology recurrent The objectives this study were to describe incidence, clinical characteristics, outcome, development retrospectively analyzed medical records 117 HCT patients, developed more than days their allogeneic...

<sec> <title>UNSTRUCTURED</title> The novel coronavirus disease 2019 (COVID-19) continues to spread over the world and there is still no specific treatment. Beside many drug studies, not enough data about place of cellular therapies. In this study, we used second passage cGMP grade umbilical cord-derived Mesenchymal Stromal Cell (MSC) via a combined intratracheal/intravenous route as administration protocol. After treatment, values inflammatory biomarker C-reactive protein all patients...
