Atypical anti-NMDA receptor encephalitis associated with varicella zoster virus infection.

J Neurovirol 2022 May 23. Epub 2022 May 23.

Neurology Department, Mongi Ben Hamida Institute of Neurology, University of Tunis El Manar, Omar Chedly Street 1029, Bab Saâdoun, Tunis, Tunisia.

The triggering effect of herpes simplex virus infection on the development of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is now well established. However, there are very few reports that has linked a varicella zoster virus (VZV) reactivation with anti-NMDAR encephalitis. In this report, we describe a case of a 57-year-old man presented with atypical clinical presentation of anti-NMDAR encephalitis with gait ataxia, complete ophtalmoplegia, and abolished reflexes followed by drowsiness and confusion.

School of Public Health, Kyoto University, Kyoto, Japan.

Public health and social measures (PHSMs) targeting the coronavirus disease 2019 (COVID-19) pandemic have potentially affected the epidemiological dynamics of endemic infectious diseases. In this study, we investigated the impact of PHSMs for COVID-19, with a particular focus on varicella dynamics in Japan. We adopted the susceptible-infectious-recovered type of mathematical model to reconstruct the epidemiological dynamics of varicella from Jan. Read More

Development of an Indirect ELISA Kit for Rapid Detection of Varicella-Zoster Virus Antibody by Glycoprotein E.

Front Microbiol 2022 27;13:897752. Epub 2022 Apr 27.

School of Life Sciences, Zhengzhou University, Zhengzhou, China.

Varicella-zoster virus (VZV), a highly infectious agent that causes varicella (chickenpox), can also cause zoster (shingles), a disorder that is frequently associated with severe neuralgia. A reliable serological VZV diagnostic assay would be useful for identifying unprotected individuals and for surveilling post-vaccination immunoprotection status. Toward this goal, VZV membrane glycoprotein E (gE), the immunodominant VZV protein, served as target antigen in an indirect ELISA kit developed here to detect anti-VZV antibodies in clinical samples.

Fragment Size-Based Enrichment of Viral Sequences in Plasma Cell-Free DNA.

J Mol Diagn 2022 May 22;24(5):476-484. Epub 2022 Feb 22.

Department of Laboratory Medicine and Pathology, University of Washington Medical Center, Seattle, Washington; Vaccine and Infectious Disease Division, Fred Hutchinson Cancer Research Center, Seattle, Washington. Electronic address:

Sequencing of plasma cell-free DNA (cfDNA) is a promising milieu for broad-based cancer and infectious disease diagnostics. The performance of cfDNA sequencing for infectious disease diagnostics is chiefly limited by inadequate analytical sensitivity. The current study investigated whether the analytical sensitivity of cfDNA sequencing for viral diagnostics could be improved by selective sequencing of short cfDNA fragments, given prior observations of shorter fragment size distribution in microbial and cytomegalovirus-derived cfDNA compared with human-derived cfDNA.

Viral Pneumonias.

Radiol Clin North Am 2022 May;60(3):383-397

Department of Radiology, MSC 10 5530, 1 University of New Mexico, Albuquerque, NM 87131-0001, USA.

Viral pneumonia is usually community acquired and caused by influenza, parainfluenza, respiratory syncytial virus, human metapneumovirus, and adenovirus. Many of these infections are airway centric and chest imaging demonstrates bronchiolitis and bronchopneumonia, With the exception of adenovirus infections, the presence of lobar consolidation usually suggests bacterial coinfection. Community-acquired viral pathogens can cause more severe pneumonia in immunocompromised hosts, who are also susceptible to CMV and varicella infection. Read More

Biochem Biophys Res Commun 2022 Apr 26;613:41-46. Epub 2022 Apr 26.

Department of Immunochemistry, Research Institute for Microbial Diseases, Osaka University, 3-1 Yamadaoka, Suita, Osaka, 565-0081, Japan; WPI Immunology Frontier Research Center, Osaka University, 3-1 Yamadaoka, Suita, Osaka, 565-0081, Japan; Center for Infectious Disease Education and Research, Osaka University, Osaka, 565-0871, Japan. Electronic address:

Varicella-zoster virus (VZV) first infects hematopoietic cells, with the infected cells then acting to distribute the virus throughout the body. Sialic acid-binding immunoglobulin-like lectin (Siglec) family molecules recognize sialic acid-containing molecules on the same cell surface, called cis-ligands, or molecules on other cells or soluble agents, called trans-ligands. Among the Siglec family molecules, Siglec-4 and Siglec-7 mediate VZV infection through association with glycoprotein B (gB). Read More
