Abstract Few studies have evaluated the prevalence of replicating hepatitis C virus (HCV) infection in sub-Saharan Africa. Among 1812 individuals infected with human immunodeficiency virus, no patient in rural Mozambique and 4 patients in urban Zambia were positive for anti-HCV antibodies. Of these, none had confirmed HCV replication.

Introduction: In Portugal, the prevalence of hepatitis A virus infection has decreased in the past decades, especially in young adults. The aim of this study was to detect the prevalence of antibody to hepatitis A virus in a population observed in our Travel Clinic.Material and Methods: Antibodies against hepatitis A, hepatitis B, hepatitis C and human immunodeficiency virus were tested using standard enzyme immunoassay in patients older than 18. The exclusion criteria were: prior vaccination for hepatitis A virus, previous diagnosis of infection with hepatitis B virus, hepatitis C virus and/or human immunodeficiency virus, foreign travelers and long-term expatriates. We applied an epidemiological survey and data was statistically analyzed with SPSS® 18.0.Results: In the 665 travelers studied, natural immunity to hepatitis A virus was present in 57.6% (n = 383). They were stratified into 8 age groups and for each one hepatitis A immunity was clarified: 5.0% (n = 1) in 18 - 25 years, 32.3% (n = 21) in 26 - 30 years, 40.9% (n = 47) in 31 - 35 years, 45.8% (n = 54) in 36 - 40 years, 68.7% (n = 79) in 41 - 45 years, 70.1% (n = 68) in 46 - 50 years, 80.8% (n = 63) in 51 - 55 years and 87.7% (n = 50) over 56 years old. In those who accepted further screening, positivity for hepatitis B core antibody was found in 0.6% (n = 3) travelers, hepatitis C virus infection in 1.1% (n = 6) and human immunodeficiency virus infection in 0.5% (n = 3) whose previous status was unknown. The most frequent travel destination was sub-Saharan Africa (72.6%; n = 483).Discussion: We found 49.1% (n = 260) travelers under 50 years old susceptible to hepatitis A virus infection and for those between 40 and 50 years, 30.7% (n = 65) still need vaccine protection.Conclusion: Across age groups there is a trend towards lower prevalence of hepatitis A virus antibody, in particular among youngsters, when compared with older Portuguese studies.

Screening of undocumented migrants or refugees for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections has been offered free of charge and free from bureaucratic procedures since 2012 at four primary-level clinical centres in Naples and Caserta, Italy. Of 926 undocumented migrants and refugees visiting one of the primary-level clinical centres from January 2012 to June 2013, 882 (95%) were screened for hepatitis B surface antigen (HBsAg), total hepatitis B core antibody (anti-HBc) and antibodies against HCV and HIV. Of the 882 individuals enrolled, 78 (9%) were HBsAg positive, 35 (4%) anti-HCV positive and 11 (1%) anti-HIV positive (single infections); seven (1%) had more than one infection (three were HBsAg positive). Of the 801 HBsAg-negative patients, 373 (47%) were anti-HBc positive. The HBsAg-positivity rate was high (14%; 62/444) in individuals from sub-Saharan Africa and intermediate in those from eastern Europe (6%; 12/198), northern Africa (2%; 2/80) and Bangladesh, India, Pakistan and Sri Lanka (the ‘India-Pakistan area’) (3%; 4/126). Anti-HCV was detected in 9/126 (7%) individuals originating from the India-Pakistan area, in 12/198 (6%) from eastern Europe, in 17/444 (4%) from sub-Saharan and in 2/80 (2%) from northern Africa. The HBV, HCV and HIV infections in the undocumented migrants and refugees screened serve as a reminder to the Italian healthcare authorities to carry out extensive screening and educational programmes for these populations.

<b><i>Background:</i></b> Although transmission of pathogenic viruses through human tissue grafts is rare, it is still one of the most serious dreaded risks of transplantation. Therefore, in addition to the detailed medical and social history, a comprehensive serologic and molecular screening of the tissue donors for relevant viral markers for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) is necessary. In the case of reactive results in particular, clear decisions regarding follow-up testing and the criteria for tissue release must be made. <b><i>Methods:</i></b> Based on the clinical relevance of the specific virus markers, the sensitivity of the serological and molecular biological methods used and the application of inactivation methods, algorithms for tissue release are suggested. <b><i>Results:</i></b> Compliance with the preanalytical requirements and assessment of a possible hemodilution are mandatory requirements before testing the blood samples. While HIV testing follows defined algorithms, the procedures for HBV and HCV diagnostics are under discussion. Screening and decisions for HBV are often not as simple, e.g., due to cases of occult HBV infection, false-positive anti-HBc results, or early window period positive HBV NAT results. In the case of HCV diagnostics, modern therapies with direct-acting antivirals, which are often associated with successful treatment of the infection, should be included in the decision. <b><i>Conclusion:</i></b> In HBV and HCV testing, a high-sensitivity virus genome test should play a central role in diagnostics, especially in the case of equivocal serology, and it should be the basis for the decision to release the tissue. The proposed test algorithms and decisions are also based on current European recommendations and standards for safety and quality assurance in tissue and cell banking.

Abstract Background The influence of direct-acting antivirals (DAAs) on the composition of gut microbiota in hepatitis C virus (HCV)–infected patients with or without human immunodeficiency virus (HIV) is unclear. Methods We enrolled 62 patients with HCV monoinfection and 24 patients with HCV/HIV coinfection receiving elbasvir-grazoprevir from a clinical trial. Fecal specimens collected before treatment and 12 weeks after treatment were analyzed using amplicon-based 16S ribosomal RNA sequencing. Results Sustained virological response rates in the monoinfection and coinfection groups were similar (98.4% vs 95.8%). Pretreatment bacterial communities in the patient groups were less diverse and distinct from those of healthy controls. Compared with HCV-monoinfected patients, HCV/HIV-coinfected individuals showed comparable microbial alpha diversity but decreased Firmicutes-Bacteroidetes ratios. The improvement of microbial dysbiosis was observed in responders achieving sustained virological response across fibrosis stages but was not found in nonresponders. Responders with a low degree of fibrosis exhibited a recovery in alpha diversity to levels comparable to those in healthy controls. Reciprocal alterations of increased beneficial bacteria and reduced pathogenic bacteria were also observed in responders. Conclusions This study indicates a short-term effect of direct-acting antivirals in restoration of microbial dysbiosis. The favorable changes in gut microbiota profiles after viral eradication might contribute toward the reduction of HCV-related complications among infected individuals.
