Aim: The study aimed to analyze human respiratory syncytial virus (hRSV) strains in nasopharyngeal aspirates obtained retrospectively. Materials & methods: Clinical information of ARI patients (n = 53) was accessed and 2nd hypervariable region of G protein gene of RSV was sequenced and analyzed. Results: Cough (98.1%), fever 40 (75.4%) and shortness of breath 32 (60.3%) were the common symptom. Sequence determination (n = 45) categorized all the strains in ON1 genotype. Potential O- and N- glycosylation were observed at some sites and purifying selections were observed at 274 and 320 codon positions. Conclusion: The study reports replacement of other RSVA genotypes with ON1. The future course of studies should emphasize on clinical implications of presence of hRSVA-ON1 genotype in a given population.

Aim: The antiviral potentials of rosmarinic acid (RA) against Rift Valley fever (RVF) virus were investigated. Methods: Antiviral activity was investigated by evaluating the reduction in the viral infectivity titer. Computational and LC–MS studies were performed for investigating the mechanism of action. This is via testing the interaction between RA and its major metabolite with the key infectivity proteins and determination of RA cellular permeability. 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. Conclusion: These antiviral potentials might suggest a promising foundation for future anti-RVF drug development.
目的:研究迷迭香酸(RA)对裂谷热(RVF)病毒的抗病毒潜力。方法:通过评估病毒感染率的降低来研究其抗病毒活性:通过评估病毒感染滴度的降低情况来研究其抗病毒活性。为研究其作用机制,进行了计算和 LC-MS 研究。具体方法是测试 RA 及其主要代谢物与关键感染性蛋白之间的相互作用,并确定 RA 的细胞渗透性。结果在感染后使用 RA,RVF 感染性滴度明显降低(45.5%),而在感染前使用 RA,感染性滴度降低 17.7%。记录的数据表明,RA 及其代谢物对 RVFV 的帽结合蛋白和糖蛋白 C 有抑制潜能,而这两种蛋白是病毒转录不可或缺的成分。液相色谱-质谱(LC-MS)显示,细胞中含有 RA,支持其在细胞内与病毒相互作用。结论这些抗病毒潜力可能为未来开发抗 RVF 药物奠定了良好基础。

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. Clinical Trial Registration: NCT04449029 (B-Clear study) ( ClinicalTrials.gov )

Aim: The HIV-V3 sequence influences tropism via the interaction of HIV with CCR5 and CXCR4 coreceptors; however, no consistent sequence accounts for R5 or X4-virus. Methods: RT-Nested PCR was performed to define V3-tropism in 123 samples using genotypic methods, including Geno2Pheno, WebPSSM, PhenoSeq, Net Charge and the 11/25 rule. 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. Proviral DNA (pvDNA) tropism result can be an appropriate target for V3-tropism determination.

Aim: Sotrovimab is an engineered human monoclonal antibody that binds a conserved region of the SARS-CoV-2 spike protein. The COMET-ICE phase III study evaluated sotrovimab for treatment of mild to moderate COVID-19 in nonhospitalized participants with ≥1 risk factor for severe disease progression. Materials & methods: We evaluated the presence of circulating SARS-CoV-2 variants of concern or interest (VOCs/VOIs) and characterized the presence of baseline, post-baseline and emergent amino acid substitutions detected in the epitope of sotrovimab in SARS-CoV-2. Results: None of the sotrovimab-treated participants with baseline epitope substitutions, and 1 of 48 sotrovimab-treated participants with post-baseline epitope substitutions, met the primary clinical endpoint for progression. Conclusion: Overall, progression was not associated with identified VOC/VOI or the presence of epitope substitutions in sotrovimab-treated participants.

Aim: Virtual screening of deep-sea fungal metabolites against SARS-CoV-2 Delta and Omicron spikes as potential antivirals. Materials & methods: Deep-sea fungal alkaloids (n ≥ 150) were evaluated against SARS-CoV-2, Delta and Omicron spikes, using various in silico approaches, including Admet scores, physiochemical properties, molecular docking (MD) and MD simulation (150 ns). Results: The test alkaloids complied with Admet scores and physiochemical properties within acceptable ranges, and followed Lipinski's rule of five. Of these, Cladosporium sphaerospermum-derived cladosin K (tetramate alkaloid) for SARS-CoV-2, Cystobasidium laryngis-derived saphenol (phenazine alkaloid) for Delta and Chaetomium globosum-derived chaetoglobosin E (quinoline alkaloid) for Omicron were identified as potential spike-inhibitors. Conclusion: Our data therefore, strongly warrants further experimental validations of cladosin K, saphenol and chaetoglobosin E, especially against the Omicron and Delta spikes.

The unprecedented scale of the SARS-CoV-2 pandemic has driven considerable investigation into novel antiviral treatments since effective vaccination strategies cannot completely eradicate the virus. Apitherapy describes the medicinal use of bee venom, which may be an effective treatment against SARS-CoV-2 infection. Bee venom contains chemicals that are antimicrobial and stimulate the immune system to counteract viral load. The present review focuses on the use of bee venom as a possible treatment for COVID-19 and reviews studies on the pharmacodynamics of bee venom.
