Results: A superior reduction in RVF infectivity titer (45.5%) was observed when RA was applied post-infection compared to 17.7% reduction following its application before infection in addition to time-dependent inactivation kinetics. Recorded data showed in-silico inhibitory potential of RA and its metabolite against RVFV cap-binding protein and glycoprotein C, which are integral for viral transcription. LC–MS revealed cellular inclusion of RA, supporting its intracellular viral interaction.

Cremer, Dickens Theodore","doi":"10.2217/fvl-2023-0117","DOIUrl":"https://doi.org/10.2217/fvl-2023-0117","url":null,"abstract":"This is a summary for the hepatitis B community providing straightforward information on the results of a study called ‘B-Clear’. Hepatitis B is an infection of the liver caused by a virus. Chronic hepatitis B is a long-lasting infection and occurs when the body is unable to fight off the virus and it persists in the blood and liver. Chronic hepatitis B virus infection is a major global health problem affecting approximately 296 million people. Current standard therapies, such as nucleotide analogs (antiviral therapy), rarely lead to a cure. This study investigated a new treatment for chronic hepatitis B virus infection, called bepirovirsen, alone or in combination with nucleotide analogs (antiviral therapy), in participants with chronic hepatitis B virus infection. The duration of treatment was 6 months. In this study, bepirovirsen was tested to see if it could decrease the levels of hepatitis B surface antigen and viral DNA to the point where they cannot be detected anymore in the blood and whether participants would maintain undetectable levels for 6 months after the end of treatment. Six (9%) participants who were currently on nucleotide analogs (antiviral therapy) and also received bepirovirsen and 7 (10%) participants who only received bepirovirsen, achieved undetectable levels of hepatitis B surface antigen and viral DNA for 6 months after the end of treatment. These results show that bepirovirsen could be an effective treatment for chronic hepatitis B virus infection. The loss of hepatitis B surface antigen seen in some participants means that bepirovirsen has the potential to reduce the risk of liver complications, such as liver failure and liver cancer and provide patients with an alternative option to lifelong treatment. Achieving undetectable levels of hepatitis B surface antigen and viral DNA may also have a positive impact on the quality of life of participants by reducing stigma and discrimination related to hepatitis B and offer relief from the hopelessness that often comes with a chronic hepatitis B virus infection diagnosis and need for lifelong therapy. Larger and longer studies are needed to confirm the results of the B-Clear study and to further evaluate how well bepirovirsen works in treating chronic hepatitis B virus infection as well as to assess its safety.

Results: Among the samples studied, the HIV-1 R5 tropic viruses were predominant. However, X4 tropism could be a reason for the higher risk of treatment failure. A good accordance was observed between paired DNA/RNA tropism results. Conclusion: CCR5 inhibitors can be crucial in simplifying HIV treatment in Iranian patients. X4-virus is a risk factor for treatment failure.

Vaccination programs have had a remarkable impact on the control of the COVID-19 burden with reports of greater than 90% reductions in mortality rate observed in vaccinated individuals of all ages and reductions in hospitalization by 71–87% [2], though it should be noted that the efficacies of different vaccines against variants of SARS-CoV-2 are variable [1]. However, the long-term safety of COVID-19 vaccines may have been overlooked as a result of the immediacy of the pandemic. Some short-term side effects of the vaccines have gradually become evident; apart from general side effects such as fatigue, headaches, muscle pain and chills, COVID-19 vaccination has been shown to trigger the development of various autoantibodies associated with autoimmune diseases including IgA nephropathy and autoimmune vasculitis [3,4]. Adenoviral-based vaccines are one type of vaccine platform that has been developed for COVID-19 vaccination and warrants further investigation for their potential long-term side effects. These vaccines use a viral vector to deliver a genetic sequence encoding an immunogenic antigen into host cells to elicit transient antigen expression and a prophylactic immune response, but some reports suggest that they may have the potential for genome integration.Viruses have been harnessed as gene-delivery tools in genetic engineering for their biological functions and, while there are also non-viral gene-delivery approaches, viral vectors are known as the most efficient to","PeriodicalId":12505,"journal":{"name":"Future Virology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135823841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
