Abstract

To study possible immunogenetic HLA markers of chronic viral hepatitides. Using the reaction of complement-dependent cytotoxicity by Terasaki, we analysed distribution of leukocytic HLA antigens (loci A, B and C) in 179 patients with chronic viral hepatitides B, C and D in Russians and Kazakhs living in the Astrakhan Region. In the Russian population we discovered a significant positive association of CVHB with HLA-B18, HLA-B35, HLA-B40, HLA-Cw3 antigens, and negative one--with HLA-A2. In Kazakhs with CVHB there was a positive association with HLA-A3, HLA-B18 and negative one--with HLA-A11. Alleles HLA-A10, HLA-B35, HLA-B40 and HLA-Cw3 mark CVHC in Russians. HLA-Cw4 specificity acts as protector in development of chronic HCV-infection. A correlation was found between carriage of some specificities and haplotypes of HLA and activity of chronic HBV and HCV infection. A high risk of chronic delta infection in Russians is associated with HLA-B8 and HLA-B35, in Kazakhs--with HLA-B35 and HLA-D40. There are significant associations between CVHB, CVHC, chronic delta infection and some HLA haplotypes. A universal role of HLA-B35 specificity in development of CVH irrespective of hepatotropic virus and patients' nationality is shown.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
