Background & Aims: This analysis reports the rate of sustained virological response (SVR) in patients infected with hepatitis C virus (HCV) genotype 1 or 4 who were assigned to 24 weeks of treatment with pegylated interferon (peginterferon) alfa-2a 180 mug/wk plus ribavirin 1000/1200 mg/day after achieving a rapid virological response (RVR; HCV RNA level <50 IU/mL) at week 4 in a prospective trial investigating response-guided therapy.
Methods: Non-RVR patients with an early virological response were randomized to 48 or 72 weeks of therapy (this is a still-ongoing trial).
Results: A total of 150 of 516 patients (29%) had an RVR, 143 of whom completed 24 weeks of treatment. Younger patients, leaner patients, and those with an HCV RNA level
Conclusions: This prospective study confirms that a 24-week regimen of peginterferon alfa-2a plus ribavirin 1000/1200 mg/day is appropriate in genotype 1 and 4 patients with a low baseline HCV RNA level who achieve an RVR by week 4 of therapy.

Given the rapid cross-country spread of SARS-CoV-2 and the resulting difficulty in tracking lineage spread, we investigated the potential of combining mobile service data and fine-granular metadata (such as postal codes and genomic data) to advance integrated genomic surveillance of the pandemic in the federal state of Thuringia, Germany. We sequenced over 6500 SARS-CoV-2 Alpha genomes (B.1.

Severe cases of COVID-19 are associated with immune responses that lead to a surge in inflammatory molecules, resulting in multi-organ failure and death. This significant increase in inflammatory factors is triggered by viral proteins. Open reading frame 8 (ORF8) has received particular attention as a unique accessory protein of SARS-CoV-2.

Background: Several respiratory viruses, including Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2), suppress nuclear factor-E2-related factor-2 (NRF2) antioxidant response, generating oxidative stress conditions to its advantage. NRF2 has also been reported to regulate the innate immune response through the inhibition of the interferon (IFN) pathway. However, its modulation in younger individuals and its correlation with the IFN response remain to be elucidated.

Serum amyloid A (SAA) is a key biomarker for diagnosing inflammatory responses in diseases like influenza and COVID-19. An electrochemiluminescence (ECL) biosensor has been constructed for signal enhancement in SAA detection by encapsulating 4,4',4″,4‴-(1,3,6,8-pyrenetetrayl) tetrakis-benzoic acid (TBAPy) into liposomes. Such biomimetic encapsulation shields the biologically important membrane to avoid aggregation of TBAPy and prevents quenching.
