Cytomegalovirus (CMV) infection is an important cause of morbidity and mortality after solid organ transplantation. CMV infection after kidney transplantation was confirmed in 19 (54.3%) out of 35 patients. 16 of these (84.2%) developed CMV disease. CMV infection was diagnosed based on a fourfold or greater increase of anti-CMV IgG antibody titre, detection of CMV-IgM antibodies and/or virus isolation. Primary infection was observed in 3 patients, reactivation in 9 and an undefined type of infection in 7. In most patients (63%), infection was diagnosed in the first 2 months, and in 3 patients, after 3, 5 and 9 years following kidney transplantation. The most frequent symptoms of CMV disease were fever (58%), pneumonitis (26.3%) and enterocolitis (15.8%). In 53% of the patients, CMV infection co-occurred with other pathogens such as Candida albicans. Cryptococcus neoformans, bacteria or viruses (HBV, HCV, HSV). Treatment with polyvalent globulin (Sandoglobin) or hyperimmune globulin (Cytotect), in combination with ganciclovir in 7 patients, resulted in a regression of CMV disease.

January 2025

Medical Practice Evaluation Center, the Division of Infectious Disease, and the Division of Maternal Fetal Medicine, Massachusetts General Hospital, Boston, Massachusetts; the Department of Pediatrics, Centre Hospitalier Universitaire Sainte-Justine, University of Montreal, Montreal, Quebec, Canada; and the Department of Obstetrics and Gynecology, Weill Cornell Medicine, New York, New York.

The purpose of this review is to serve as an update on congenital cytomegalovirus (CMV) evaluation and management for obstetrician-gynecologists and to provide a framework for counseling birthing people at risk for or diagnosed with a primary CMV infection or reactivation or reinfection during pregnancy. A DNA virus, CMV is the most common congenital viral infection and the most common cause of nongenetic childhood hearing loss in the United States. The risk of congenital CMV infection from transplacental viral transfer depends on the gestational age at the time of maternal infection and whether the infection is primary or nonprimary.

Objectives: The present study aims to identify potential predictive factors for developing sensorineural hearing loss (SNHL) in individuals with congenital Cytomegalovirus (cCMV) infection.

Methods: A retrospective study was performed on 50 subjects with cCMV infection (symptomatic and asymptomatic), followed at the Audiology Service of Sant'Anna Hospital (University Hospital of Ferrara). The following data were analyzed: the type of maternal Cytomegalovirus (CMV) infection (primary versus non-primary), time of in utero infection, systemic signs and symptoms or laboratory test anomalies due to cCMV infection, and signs and symptoms of central nervous system (CNS) involvement at birth.

Purpose: This multicenter study aimed to investigate the clinical characteristics and factors associated with specific viral pathogens in patients with acute retinal necrosis (ARN).

Methods: A retrospective multicenter cohort study included ARN patients who underwent aqueous or vitreous polymerase chain reaction (PCR) testing. Multivariable mixed-effects Poisson regression was used to identify factors associated with viral pathogens.

This study investigates the application of levan- produced from Paenibacillus polymyxa SG09-12 as an antiviral agent against cucumber mosaic virus (CMV). A high-purity microbial levan was produced and purified using diafiltration. The chemical composition, structure, and functional groups of the levan were characterised using high-performance liquid chromatography (HPLC), nuclear magnetic resonance (NMR), Fourier-transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS).
