Epidemiological Situation

Introduction: The ongoing adverse situation with the prevalence of chronic hepatitis C virus (HCV) infection makes it especially relevant to assess the epidemiological situation of this infection in the country as a whole and the Samara Region. Our objective was to determine characteristics of the epidemic process of chronic HCV infection in the territory of the Russian Federation and the Samara Region in 1997–2018. Results and discussion: We observed a dynamic 5.88-fold increase in the Russian rates of chronic HCV infection in 1997–2014 from 6.7 0/0000 to 39.4 0/0000 (p < 0.01) followed by a decrease by 16.5 % in 2015–2018 (from 39.2 0/0000 to 32.7 0/0000). In the Samara Region, we traced a periodic wave-like increase alternating with small drops in the prevalence rates during the whole observation period. In 1997–2016, the rates of chronic HCV infection rose from 5.2 0/0000 to 58.0 0/0000 (by 11.2 times; p < 0.01) and declined slightly from 58.0 0/0000 to 56.2 0/0000 in 2016–2018. The maximum rates of chronic HCV infection in the child population of the Samara Region were registered in 2002 and 2012 (7.1 0/0000 and 7.2 0/0000, respectively) with the minimum of 1.9 0/0000 noted in 2017. The analysis of the epidemiological situation of chronic hepatitis is important for subsequent trend forecasting and developing appropriate preventive measures.

BACKGROUND/OBJECTIVE: Liver biopsy has been the gold standard for grading and staging chronic hepatitis C virus (HCV)-mediated liver injury. Traditionally, this has been performed by trained practitioners using a nonimage-guided percutaneous technique at the bedside. Recent literature suggests an expanding role for radiologists in obtaining biopsies using an ultrasound (US)-guided technique. The present study was undertaken study to determine if the two techniques produced liver biopsy specimens of similar quality and hypothesized that at our institution, non-US-guided percutaneous liver biopsies for HCV would be of higher quality than US-guided specimens.METHODS: Liver biopsies from 100 patients with chronic HCV infection (50 consecutive US-guided and 50 consecutive non-US-guided), were retrospectively identified using a hospital histopathology database. All original biopsy slides were coded and prospectively reanalyzed by a single hepatopathologist who was blinded to the technique used in obtaining the biopsy. Additionally, all liver biopsies for chronic HCV infection completed at the centre from 1998 to 2007 were identified and the technique used was recorded. Biopsy quality was determined primarily by the number of complete portal tracts (CPTs) identifiable in the slides. The total length of specimen and the degree of fragmentation were secondary outcome measures.RESULTS: There was a slight difference observed between the US-guided and non-US-guided groups in mean age (46.3 years versus 42.5 years, repectively; P=0.018) but no differences in sex, presence of cirrhosis, bilirubin, creatinine, international normalized ratio, and grade or stage of disease. Biopsies obtained using the US-guided technique produced higher quality specimens than the non-US-guided technique based on our primary outcome of number of CPTs in the biopsy (11.8 versus 7.4; P<0.001). US-guided specimens also were longer (24.4 mm versus 19.7 mm; P=0.001), had less fragmentation (P=0.016), and a higher overall histopathological quality assessment (P=0.026) than the non-US-guided biopsies. However, there was no significant difference between the two groups in the ability to grade and stage the disease (96% US-guided versus 90% in non-US-guided (P=0.20). Over a 10-year period, 763 biopsies for chronic HCV infection were identified with an obvious trend toward the increased use of US-guided technique observed at 2% in 1998 to 85% in 2007.CONCLUSIONS: US-guided liver biopsies for chronic HCV are the most common method of obtaining specimens at the Kingston General Hospital, Kingston, Ontario, and are of higher quality than non-US-guided specimens. However, there is no significant difference in the two techniques in the ability to grade and stage chronic HCV.

Introduction. The incidence of chronic hepatitis C virus (HCV) infection is rather high. Its most frequent consequences are chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. Treatment of chronic HCV infection. In treatment of chronic HCV infection, interferons have antiviral, anriproliferative, and immunoregulatory action. Within the cell, they induce protein synthesis, inhibiting viral replication. The most important among them are RNA dependent protein kinase, and eukaryotic initiation factor. However, viral proteins prevent their phosphorylation and activation. In order to overcome this problem, treatment is prolonged, higher doses of IFN are used, as well as induction therapy. The optimal period for viral response is 52 weeks, while induction therapy has shown controversial results. .

Pegylated interferon (PEG-IFN) alpha and ribavirin therapy has become the standard treatment in chronic hepatitis C virus (HCH)-infected patients. While thrombocytopenia associated with IFN use is frequently observed among these patients, autoimmune thrombocytopenia is one of the rarely observed adverse effects. In the present report, we present a case with chronic HCV infection in which autoimmune thrombocytopenia developed at week 7 of PEG-IFN alpha 2b plus ribavirin therapy. The patient subsequently received ursodeoxycholic acid (UDCA) treatment. Although there is not an adequate number of studies on this subject, it was concluded that the use of UDCA in cases of autoimmune thrombocytopenia that have developed due to PEG-IFN treatment in chronic HCV infection is a favorable option.

Background: Rheumatoid arthritis is a chronic immunological disease that causes destruction and deformity of joints. Chronic hepatitis C infection cases could develop rheumatic like clinical presenting profile. Raised rheumatoid factor in chronic HCV infection considerably reduces the diagnostic privilege of rheumatoid factor for rheumatoid arthritis coexisting with HCV infection. Aim of the work: To determine the value of anti-citrullinated protein antibody levels in cases having chronic HCV infection in comparison to rheumatoid factor. Methodology: The research team recruited 150 non-arthritic study subjects having chronic hepatitis C virus infection rheumatoid factor and anti-citrullinated protein antibody levels were assayed for all study subjects for statistical analysis. Results: Rheumatoid factor +ve study subjects had statistically significantly more frequent within female gender. (p value=0.027) Rheumatoid factor high +ve cases had statistically significantly had more frequent fatty liver and higher platelets than on high RF +ve cases. (P value =0.020, <0.038 consecutively) Conclusion: HCV cases with joint involvement were not implemented in the current research study that prevented statistical estimation of the sensitivity of anti-citrullinated protein antibody for arthritis in this cohort. Racial and ethnic differences should be put in consideration in future research studies that are recommended to be multi centric in fashion.

ABSTRACT Given the failures of nonreplicating vaccines against chronic hepatitis C virus (HCV) infection, we hypothesized that a replicating viral vector may provide protective immunity. Four chimpanzees were immunized transdermally twice with recombinant vaccinia viruses (rVV) expressing HCV genes. After challenge with 24 50% chimpanzee infective doses of homologous HCV, the two control animals that had received only the parental VV developed chronic HCV infection. All four immunized animals resolved HCV infection. The difference in the rate of chronicity between the immunized and the control animals was close to statistical significance (P = 0.067). Immunized animals developed vigorous gamma interferon enzyme-linked immunospot responses and moderate proliferative responses. To investigate cross-genotype protection, the immunized recovered chimpanzees were challenged with a pool of six major HCV genotypes. During the acute phase after the multigenotype challenge, all animals had high-titer viremia in which genotype 4 dominated (87%), followed by genotype 5 (13%). However, after fluctuating low-level viremia, the viremia finally turned negative or persisted at very low levels. This study suggests the potential efficacy of replicating recombinant vaccinia virus-based immunization against chronic HCV infection.

ABSTRACT A genetically determined resistance or susceptibility to chronic hepatitis C virus (HCV) infection may make an important contribution to the course of liver disease and may be linked to the human major histocompatibility complex (MHC). The aim of this study was to investigate the HLA class II genotype profile in chronic hepatitis C and to determine the HLA-hepatitis C association. The experimental population was composed of 49 unrelated chronic HCV patients (31 females, 18 males; mean age, 54.4 ± 1.7 years; range, 34 to 73 years). The control population consisted of 43 ethnically matched healthy donors. HLA-DR and -DQ alleles were studied for patients and controls by a PCR-sequence-specific-primer low-resolution method. Anti-HCV was investigated with enzyme-linked immunosorbent assay II, and HCV RNA was investigated with reverse transcriptase nested PCR. The HLA class II allele, DRB1*11, was found at reduced frequency in 49 patients with chronic hepatitis C (anti-HCV and HCV RNA positive) compared to that for controls (22.4 versus 51.0%; P < 0.01, odds ratio = 0.3, confidence interval = 0.1 to 0.7). No further HLA associations with chronic HCV infection were observed, and there was no correlation between the stage of disease and HLA. DRB1*11 was also found at reduced frequency in all HCV antibody-positive patients compared to controls (corrected P = not significant). DRB1*11 was associated with chronic HCV infection, and it is possible that HLA-DRB1*11 may have a protective feature in chronic HCV infection. In addition, DRB1*11 was associated with protection from HCV infection. These findings suggest that host HLA class II genotype is an important factor determining the outcome of infection with HCV.
