J Infect Chemother 2024:S1341-321X(24)00237-X. [PMID: 39197667 DOI: 10.1016/j.jiac.2024.08.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2024] [Revised: 08/07/2024] [Accepted: 08/26/2024] [Indexed: 09/01/2024]
Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), remains a global public health threat. Although several effective vaccines and therapeutics have been developed, continuous emergence of new variants necessitates development of drugs with different mechanisms of action. Recent studies indicate that cepharanthine, a chemical derivative purified from Stephania cepharantha, inhibits SARS-CoV-2 replication in vitro. METHODS This study examined the in vivo effects of cepharanthine using a Syrian hamster SARS-CoV-2 infection model. To evaluate the prophylactic and therapeutic effects, cepharanthine was intranasally administered before or after SARS-CoV-2 infection. Effects were assessed by monitoring body weight changes, lung pathology, lung viral load, and inflammatory response in the lungs. RESULTS Pre-infection administration of cepharanthine resulted in less weight loss, reduced virus titers, alleviated histopathological severity, and decreased lung inflammation. Furthermore, post-infection administration of cepharanthine also exhibited therapeutic effects. CONCLUSIONS This study demonstrated that both prophylactic and therapeutic administration of cepharanthine reduces the pathogenesis of COVID-19 in a Syrian hamster SARS-CoV-2 infection model. Our findings suggest that cepharanthine is a potential therapeutic agent against COVID-19.

Abstract
Background and objective Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has broad tissue tropism and high transmission, which are likely to perpetuate the pandemic. The study aim to analyze the clinicopathogenic characteristics in paediatric patients. Methods In this single-centre study, we retrospectively included all confirmed cases infected by SARS-CoV-2 infection at Xi'an Children's Hospital, China, from 1 December to 31 December 2022. The demographic, clinical, laboratory, and radiological features of the patients were analysed. Results A total of 4,520 paediatric patients with SARS-CoV-2 omicron variant infections were included. Of these, 3,861 (85.36%) were outpatients, 659 (14.64%) were hospitalised patients, and nine patients (0.20%) died. Of the nine patients who died, five were diagnosed with acute necrotising encephalopathy (ANE). The most common symptoms were fever in 4,275 (94.59%) patients, cough in 1,320 (29.20%) patients, convulsions in 610 (13.50%) patients, vomiting in 410 (9.07%) patients, runny nose/coryza in 277 (6.13%) patients, hoarseness of voice in 273 (6.04%) patients. A blood cell analysis showed a slight elevation of monocytes (mean: 11.14 ± 0.07%). The main diagnoses for both outpatients and inpatients were respiratory infection with multisystem manifestations. Conclusions A high incidence of convulsions is a typical characteristic of children infected with SARS-CoV-2. Five of the nine COVID-19 fatalities were associated with ANE. This indicates that nervous system damage in children with SARS-CoV-2 infection is more significant.

Abstract
OBJECTIVE The function of Bcl-6 in T follicular helper (Tfh) cell maturation is indispensable, and Tfh cells play a pivotal role in asthma. This study investigated the impact of Bcl-6 on asthmatic traits. METHODS The microscopic pathological alterations, airway resistance (AR), and lung compliance (LC) were determined in asthmatic mice and Bcl-6 interference mice. The surface molecular markers of Tfh cells and the Bcl-6 mRNA and protein expression were determined by flow cytometry, RT-qPCR, and Western blotting, respectively. The relationships between the Tfh cell ratio and the IgE and IgG1 concentrations in peripheral blood mononuclear cells (PBMCs) and bronchoalveolar lavage fluid (BALF) were determined. RESULTS Asthmatic inflammatory changes were observed in the lung tissue and were attenuated by Bcl-6 siRNA and dexamethasone (DXM). Asthmatic mice exhibited an increased AR and a decreased LC, while Bcl-6 siRNA or DXM mitigated these changes. The percentages of Tfh cells and eosinophils were significantly increased in the asthmatic mice, and they significantly decreased after Bcl-6 inhibition or DXM treatment. RT-qPCR and Western blotting analyses revealed that the Bcl-6 expression level in PBMCs was significantly higher in asthmatic mice, and it decreased following Bcl-6 inhibition or DXM treatment. The IgE expression in the serum and BALF and the B cell expression in PBMCs exhibited a similar trend. In asthmatic mice, the ratio of Tfh cells in the peripheral blood showed a strong positive correlation with the IgE levels in the serum and BALF, but not with the IgG1 levels. CONCLUSION The amelioration of airway inflammation and airway hyper-responsiveness is achieved through Bcl-6 suppression, which effectively hinders Tfh cell differentiation, ultimately resulting in a concurrent reduction in IgE production.
