Ninety children, aged from 7 days to 12 months, with perinatal damage of the central nervous system (CNS) were virologically tested. The persistence of cytomegalovirus (CMV) DNA in the blood, urine and oropharyngeal swabs was identified in 18.9% of children. In 14.4% of children, CMV DNA was found only in oropharyngeal swabs and urine samples. In some cases, the severity of neurologic symptoms and absence of positive changes in the restoration treatment could be caused by the activity of CMV infection, blood CMV DNA and the increase in blood-brain barrier permeability. The authors recommend performance of a comprehensive immunological and molecular-biological survey in patients with suspected CMV infection. In case of positive reactions, a specific antiviral treatment should be started. Tree clinical cases are reported.

Introduction: The extent to which commercially available nucleic acid extraction platforms impact the magnitude of Cytomegalovirus (CMV) DNA loads measured in plasma specimens by 1st WHO standard-normalized real-time PCR assays is uncertain.
Methods: This retrospective study compares the performance of Abbott m2000sp, Qiagen QIAsymphony SP, and KingFisher Flex platforms using plasma samples from allogeneic hematopoietic stem cell transplant recipients and plasma spiked with the CMV AD169 strain. The Abbott RealTime CMV PCR assay was used for CMV DNA quantitation.

Cytomegalovirus (CMV) infection is one of the most prevalent opportunistic infections after hematopoietic stem cell transplantation (HSCT). Prophylaxis and preemptive therapy have demonstrated promise in reducing the incidence of CMV infection and CMV disease, but the management of refractory/resistant (R/R) CMV infections after HSCT remains a challenge that significantly affects the prognosis of patients undergoing HSCT. Intolerance and resistance to antivirals are the primary reasons for developing refractory CMV infections.

This study aimed to analyze cytomegalovirus (CMV) reactivation and its influencing factors in patients with B-lymphocyte malignancy who received chimeric antigen receptor T (CAR-T) cell therapy. This study retrospectively reviewed patients with B-lymphocyte malignancy who received CAR-T cell therapy in the First Affiliated Hospital of Soochow University from January 2021 to December 2023. The data of patients who underwent CMV-DNA detection and/or pathogen metagenomic sequencing twice or more within 100 days after CAR-T cell therapy were analyzed.

People living with HIV (PLWH) beginning antiretroviral therapy (ART) retain a high burden of cytomegalovirus (CMV). CMV has been implicated in atherosclerosis in healthy adults, and a role in PLWH is plausible. Atherosclerosis has also been linked with γδ T cells and CMV seropositivity with altered γδ T cell profiles in other populations.

Objective: The impact of cytomegalovirus (CMV) on inflammatory bowel disease (IBD) flares remains a matter of debate. This study aimed to evaluate patients with CMV infection who presented with IBD exacerbation in terms of diagnosis and treatment and investigate the importance of CMV DNA levels in colitis development.
Materials And Methods: Patients who were followed up with IBD and examined with clinical suspicion of CMV colitis at a university hospital between January 2016 and December 2021 were retrospectively scanned.
