Background The respiratory syncytial virus (RSV) is the main cause of bronchiolitis in infants and interferon (IFN) α is a commercial antiviral drug. The nebulization of IFN α1b could be a viable treatment method. In this study, the therapeutic effects and safety of IFN α1b delivery via nebulization in infant bronchiolitis were investigated in this multi-center prospective study. Methods and findings Bronchiolitis patients admitted to 22 hospitals who met the inclusion criteria were enrolled and randomly allocated to four groups: control, IFN Intramuscular Injection, IFN Nebulization 1 (1 μg/kg), and IFN Nebulization 2 (2 μg/kg) groups. All patients were observed for 7 days. The therapeutic effects and safety of different IFN delivery doses and delivery modes were evaluated. Coughing severity change, as scored by the researchers and parents, between days 1 and 3 was significantly different between the IFN Nebulization 2 and control
Diarrhea, fever, and abdominal pain were the three most common clinical manifestations observed in patients infected with S. sonnei. High-level antibiotic resistance was observed among Shigella species.
BackgroundTo investigate the effects of co-infection with C. sinensis on T cell exhaustion levels in patients with chronic hepatitis BMethodsInhibitory receptors and suppressive cytokines expression in circulating CD4+ and CD8+ T cells was detected by flow cytometry. The correlations between PD-1 and TIM-3 expression and alanine aminotransaminase (ALT) levels, aspartate aminotransferase (AST) levels and HBV DNA levels were analyzed using GraphPad Prism 7.0. ResultsPD-1 and TIM-3 expression levels were significantly higher on CD4+T and CD8+T cells from co-infected patients than on those from the HBV patients. In addition, CD4+T cells and CD8+T cells function was inhibited by C. sinensis and HBV coinfection, secreting low levels of IFN-γ, IL-2 and TNF-α. Then, a significant positive correlation was found between the PD-1 and TIM-3 expression levels on T cells and the AST ,ALT levels and HBV DNA levels.ConclusionsOur current results suggested that C. sinensis co-infection could exacerbate T cell exhaustion in patients with chronic hepatitis B. Furthermore, it maybe one possible reason for the weaker response to antiviral therapies and the chronicity of HBV infection in co-infected patients. We must realize that the importance of C.sinensis treatment for HBV infected patients. It might provide useful information for the clinical doctors to choose the right treatment plans.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
