Serologic Status of Routine Childhood Vaccines, Cytomegalovirus, and Epstein-Barr Virus in Children With Inflammatory Bowel Disease.

Inflamm Bowel Dis 2018 Dec 14. Epub 2018 Dec 14.

Section of Paediatric Gastroenterology, Department of Paediatrics, University of Calgary, Calgary, Alberta, Canada.

Background: Data on the serologic status of childhood vaccines, cytomegalovirus (CMV) and Epstein-Barr virus (EBV), are limited in inflammatory bowel disease (IBD). Therefore, we evaluated vaccine coverage and seroprotection, along with CMV and EBV seropositivity, in pediatric IBD.

Methods: In a cross-sectional study, demographic data, IBD history, vaccine records, and serum for antibodies against measles, mumps, rubella, diphtheria, tetanus, varicella, hepatitis B (HBV), CMV, and EBV were collected from children with IBD. Read More

A Clinico-epidemiological Study of Childhood Herpes Zoster.

Indian Dermatol Online J 2018 Nov-Dec;9(6):383-388

Department of Dermatology, Military Hospital, Bareilly, Uttar Pradesh, India.

Herpes zoster (HZ) is a viral infection believed to be caused by the re activation of varicella zoster virus (VZV) or human herpes virus type 3 (HHV 3) that persists in the posterior nerve root ganglion. HZ is rarely reported in the pediatric age group with an intact immunity. Past infection with VZV and immunization with chickenpox vaccine are key markers in the onset of varicella zoster in children. Read More

Live-attenuated varicella zoster virus vaccine does not induce HIV target cell activation.

J Clin Invest 2018 Dec 4. Epub 2018 Dec 4.

Background: Varicella-zoster virus (VZV) is under consideration as a promising recombinant viral vector to deliver foreign antigens including HIV. However, new vectors have come under increased scrutiny since vaccination with Ad5-vectored HIV vaccine trials demonstrated increased HIV risk in individuals with pre-immunity to the vector which was thought to be associated with mucosal immune activation (IA). Therefore, defining the impact of VZV vaccination on IA is particularly important with the prospect of developing an HIV/VZV chimeric vaccine. Read More

Xanthine-based acyclic nucleoside phosphonates with potent antiviral activity against varicella-zoster virus and human cytomegalovirus.

Antivir Chem Chemother 2018 Jan-Dec;26:2040206618813050

1 Institute of Organic Chemistry and Biochemistry, Czech Academy of Sciences, Prague, Czech Republic.

While noncanonic xanthine nucleotides XMP/dXMP play an important role in balancing and maintaining intracellular purine nucleotide pool as well as in potential mutagenesis, surprisingly, acyclic nucleoside phosphonates bearing a xanthine nucleobase have not been studied so far for their antiviral properties. Herein, we report the synthesis of a series of xanthine-based acyclic nucleoside phosphonates and evaluation of their activity against a wide range of DNA and RNA viruses. Two acyclic nucleoside phosphonates within the series, namely 9-[2-(phosphonomethoxy)ethyl]xanthine (PMEX) and 9-[3-hydroxy-2-(phosphonomethoxy)propyl]xanthine (HPMPX), were shown to possess activity against several human herpesviruses.

Based on prescriptions filled at external pharmacies, prescription surveillance (PS) in Japan has been reporting the estimated numbers of influenza and varicella patients and people prescribed certain drugs since 2009. Every morning, this system estimates the numbers of patients from the numbers of prescriptions filled nationwide for neuraminidase inhibitors, anti-herpes virus drugs, antibiotic drugs, antipyretic analgesics, and multi-ingredient cold medications. Moreover, it can detect "unexplained" infectious diseases that are not explained as infectious diseases monitored by other surveillance systems. Read More

Viral infections of the central nervous system (CNS) occur sporadically and have been extensively studied because of the potential for permanent neurological damage or death. The neurotropic viruses have been reported to lead to various CNS infections. The objective of the present study is to develop an antigen detection ELISA protocol for detection and quantification of viral antigen in CNS infections by assessing the usefulness of antipeptide antibodies against potential peptides of cytomegalovirus (CMV), Epstein-Barr virus (EBV), varicella zoster virus (VZV), Japanese encephalitis virus (JEV), dengue (DENV), West Nile virus (WNV) and Chandipura virus (CHPV).
