Humoral response to John Cunningham virus during pregnancy in multiple sclerosis [PDF]

open access: yesMultiple Sclerosis and Related Disorders, 2018
Pregnancy induces an immunosuppressive state in the mother to ensure immunological acceptance of the foetus. Impairment of cell-mediated immune responses may render the mother susceptible to intracellular pathogens. It is not presently known whether pregnancy alters the immunosurveillance for John Cunningham virus (JCV), an opportunistic pathogen ...

Considerations on the appropriateness of the John Cunningham virus antibody assay use in patients with rheumatoid arthritis

open access: yesSeminars in Arthritis and Rheumatism, 2015
The John Cunningham virus (JCV) is a generally benign and asymptomatic polyomavirus. Due to an association of the anti-integrin agent natalizumab with progressive multifocal leukoencephalopathy (PML) in patients with multiple sclerosis (MS), a newly developed anti-JCV antibody assay has been implemented as a risk-stratification tool for natalizumab ...

John Cunningham virus conversion in relation to natalizumab concentration in multiple sclerosis patients

open access: yesEuropean Journal of Neurology, 2017
Background and purposeInfection with the John Cunningham virus (JCV) is required for the development of progressive multifocal leukoencephalopathy, the feared complication of natalizumab treatment in multiple sclerosis patients. The JCV seroconversion rate seems higher in natalizumab treated patients than in the normal population, with an unknown cause.

John Cunningham Virus Status, Seroconversion Rate, and the Risk of Progressive Multifocal Leukoencephalopathy in Polish John Cunningham Virus-Seronegative Patients with Relapsing-Remitting Multiple Sclerosis

European Neurology, 2020
Introduction: Presence of anti-JC-virus antibodies (JCVAbs) is associated with the increased risk of natalizumab (NAT)-related progressive multifocal leukoencephalopathy (PML). Little is known about seroconversion rate and time to seroconversion in relapsing-remitting multiple sclerosis (RRMS) patients treated with NAT in Poland.

Distribution and Quantity of Sites of John Cunningham Virus Persistence in Immunologically Healthy Patients

JAMA Neurology, 2017
Although seroepidemiological studies indicate that greater than 50% of the population has been infected with John Cunningham virus (JCV), the sites of JCV persistence remain incompletely characterized.To determine sites of JCV persistence in immunologically healthy individuals.Tissue specimens from multiple sites including brain, renal, and nonrenal ...

JCVirusNEntamoebaNET (JCENET): A Deep Neural Network for John Cunningham Virus and Entamoeba Parasite Detection

2021 International Conference on Information and Communication Technology for Sustainable Development (ICICT4SD), 2021
Parasites and viruses are responsible for attacking the immune system of human body and destroying it in the process which makes detection of parasites and virus a penultimate task in modern medical analysis. The detection process is often characterized with symptoms, microscopic tests.
