Abstract

Background: Consensus human cytomegalovirus (HCMV) DNA cut-off values for preemptive therapy in transplant recipients have not yet been defined, mainly due to the lack of real-time PCR standardization., Objectives: (i) To compare the kinetics of HCMV DNA in transplanted patients using an in-house real-time PCR assay (Pavia assay) and the new Abbott RealTime CMV assay; (ii) to verify assay concordance in the identification of patients eligible for preemptive treatment and (iii) standardize results with international units (IUs) using the WHO International HCMV DNA Standard as a reference., Study Design: The kinetics of HCMV disseminated infection was retrospectively evaluated in 513 stored whole blood samples from 37 transplanted patients enrolled in randomized prospective studies designed for the clinical validation of HCMV DNA cut-off values. Conversion factors of HCMV DNA copy number to WHO international units (IUs) were determined., Results: Among the 513 samples, 352 (68.6%) were concordant positive, 42 (8.1%) concordant negative and 119 (23.1%) discordant. All discordant samples resulted positive by the Abbott RealTime CMV assay and negative by the Pavia assay, showing higher sensitivity for the Abbott RealTime CMV assay. A significant correlation was observed between concordant positive samples (r=0.89). HCMV DNAemia determined by each assay showed overlapping kinetics. Expression of results as IU/ml provided the best results in preemptive treatment simulation., Conclusion: HCMV DNAemia cut-off values determined using our in-house assay and expressed as IU/ml appear valid for use in commercial assays as well as other potential in-house assays., (Copyright © 2012 Elsevier B.V.

Abstract

Highlights • EBV reactivation was observed in patients with COVID-19. • NK + and CD8 + T cell reduction was related to the severity of COVID-19 infection. • An increase of B cells in patients with severe symptoms was documented., Objectives The immunologic profile and opportunistic viral DNA increase were monitored in Italian patients with COVID-19 in order to identify markers of disease severity. Methods A total of 104 patients infected with SARS-CoV-2 were evaluated in the study. Of them, 42/104 (40.4%) were hospitalized in an intensive care unit (ICU) and 62/104(59.6%) in a sub-intensive care unit (SICU). Human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV), Parvovirus B19 and Human Herpesvirus 6 virus reactivations were determined by real-time PCR, and lymphocyte subpopulation counts were determined by flow cytometry. Results Among opportunistic viruses, only EBV was consistently detected. EBV DNA was observed in 40/42 (95.2%) of the ICU patients and in 51/61 (83.6%) of the SICU patients. Comparing the two groups of patients, the EBV DNA median level among ICU patients was significantly higher than that observed in SICU patients. In parallel, a significant reduction of CD8 T cell and NK count in ICU patients as compared with SICU patients was observed (p
