AI Article Synopsis

  • The study investigates the HLA Class I and II genotype profiles in hepatitis C virus (HCV) infected patients from Northern India.
  • The research analyzed 148 anti-HCV-positive patients over a period from January 2013 to August 2014 and found significant changes in specific HLA allele frequencies compared to control groups.
  • Notably, certain HLA alleles showed geographic variation in frequencies among HCV-infected individuals in India, highlighting the potential role of genetic factors in HCV susceptibility.

Article Abstract

Purpose: Humans are the only known natural hosts of hepatitis C virus (HCV). This study was undertaken to examine the frequencies of human leucocyte antigens (HLAs) Class I and Class II genotype profiles in anti-HCV-infected patients of Northern India.

Materials And Methods: From a period of January 2013 to August 2014, 148 anti-HCV-positive patients of North India referred to the Department of Molecular Biology and Transplant Immunology, Indraprastha Apollo Hospitals, New Delhi, for performing HLA typing were included in the study.

Results: AFNx0102, AFNx0131 allele frequency decreased significantly in anti-HCV-positive patients. Frequencies for HLA-B loci did not reach any statistical significance. Among the Class II alleles, HLA-DRB1FNx0103 and HLA-DRB1FNx0110 were significantly higher in the patient population, and HLA-DRB1FNx0115 was significantly decreased in the patient population as compared to the controls.

Conclusion: HLA-AFNx0133 was significantly increased as compared to control population and showed geographic variation in HCV-infected individuals of India.

Telomere attrition is a hallmark of biological aging, contributing to cellular replicative senescence. However, few studies have examined the determinants of telomere attrition in vivo in humans. Mitochondrial Health Index (MHI), a composite marker integrating mitochondrial energy-transformation capacity and content, may be one important mediator of telomere attrition, as it could impact telomerase activity, a direct regulator of telomere maintenance.

Human adenovirus (HAdV) is a widely spread respiratory pathogen that can cause infections in multiple tissues and organs. Previous studies have established an association between HAdV species B (HAdV-B) infection and severe community-acquired pneumonia (SCAP). However, the connection between SCAP-associated HAdV-B infection and host factor expression profile in patients has not been systematically investigated.

Antibody-mediated protection against pathogens is crucial to a healthy life. However, the recent SARS-CoV-2 pandemic has shown that pre-existing comorbid conditions including kidney disease account for compromised humoral immunity to infections. Individuals with kidney disease are not only susceptible to infections but also exhibit poor vaccine-induced antibody response.
