This systematic review and network meta-analysis aims to estimate the comparative effectiveness of antivirals and mAb therapies for treating COVID-19 patients infected with Omicron, capturing primarily acute outcomes. We searched multiple databases from July 4 to July 19, 2022, with updates through November 4, 2022. Studies comparing the effectiveness of antivirals or mAb to either nonuser controls or other treatments were included. Risk of bias was assessed using the Cochrane RoB 2 and ROBINS-I tools. Data extraction and verification involved five independent researchers. Among 39 studies (727,893 individuals with COVID-19, including 38 nonrandomized trials), nirmatrelvir/ritonavir and sotrovimab were associated with lower risks of mortality (HR = 0.317, 95% credible intervals [CrI] = 0.144–0.678; HR = 0.176, 95%CrI = 0.052–0.527) and hospitalization (HR = 0.479, 95%CrI = 0.319–0.711; HR = 0.489, 95%CrI = 0.293–0.797) compared with nonuser controls. Remdesivir users were associated with a lower risk of hospitalization (HR = 0.367, 95%CrI = 0.147–0.868) but not mortality. Molnupiravir and bebtelovimab showed no significant benefits for these outcomes. In conclusion, among individuals infected with COVID-19 during the Omicron wave, mortality risk was lower with nirmatrelvir/ritonavir or sotrovimab use, whereas hospitalization was reduced with nirmatrelvir/ritonavir, remdesivir, or sotrovimab. Sotrovimab and nirmatrelvir/ritonavir were effective against Omicron B.1.1.529/BA.1 and BA.2/BA.4/BA.5 subvariants, respectively. A key limitation is that findings rely on data from the last search and may be impacted by potential changes in mortality risk due to immune evasion by emerging variants, highlighting the need for ongoing randomized trials across variants and populations.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Trial Registration</h3>\u0000 \u0000 <p>The study was registered on PROSPERO, CRD42022351508.</p>\u0000 </section>\u0000 </div>","PeriodicalId":13544,"journal":{"name":"Influenza and Other Respiratory Viruses","volume":"18 12","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11669747/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142894221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In France, Nirsevimab, a long-acting monoclonal antibody to prevent RSV-associated lower respiratory tract infections (LRTI) was available from September 2023. We described RSV-associated LRTI hospitalisations during the 2023–2024 season among infants younger than six months born at the Hospices Civils de Lyon (HCL), and evaluated the effectiveness of Nirsevimab against RSV-LRTI hospitalisation.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>This observational study included infants born and hospitalised at the HCL during the 2023–2024 season, along with pre-COVID-19 and 2022–2023 seasons. Information on Nirsevimab immunisation status, clinical and perinatal variables were collected through routine care. Infants' characteristics and incidence rate of hospitalisation per 100 births during 2023–2024 were compared with the historical periods overall and by delay between birth and the onset of the RSV season. Nirsevimab effectiveness was computed by the screening method.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>During the 2023–2024 season, 83 infants younger than six months were hospitalised with an RSV-associated LRTI. Compared with the historical periods (640 pre-COVID-19 and 123 in 2022–2023), these infants were older. Incidence rate for infants born during the period when immunisation was available were lower than the previous seasons; incidence rate ratios were 0.45 (95% confidence interval [CI]: 0.33; 0.62) in 2023–2024 compared with pre-COVID-19 period and 0.53 (95%CI: 0.36; 0.77) compared with 2022–2023 season.

Almost the entire world has been affected by H5N1; the virus has expanded to new regions such as the Americas and Antarctica for the first time in its evolutionary history [&lt;span&gt;3&lt;/span&gt;]. However, no cases of H5N1 have been detected in Oceania to date [&lt;span&gt;5, 6&lt;/span&gt;] (only one human case infected outside this continent has been reported [&lt;span&gt;7&lt;/span&gt;]). Regions not affected by this virus are of epidemiological importance, as they provide insights about potential limiting factors for its spread (e.g., geographic barriers, environmental features, wild species traits and movement). Moreover, in those areas, there is still time to prepare efficient preventive and mitigation actions to reduce the impact of this pathogen, if we can identify potential pathways of virus arrival. Here, leveraging range maps of suitable host bird species, we suggest a potential pathway of H5N1 arrival to the Oceania region that could be important to consider under the current epidemiological behavior of this virus.&lt;/p&gt;&lt;p&gt;To assess possible pathways of H5N1 arrival to Oceania (specifically, Australia, New Zealand, and Tasmania for this article), we performed a map of risk based on wild bird species already reported as infected by the virus anywhere in the world. These species could be considered suitable hosts of the virus. We integrated a list of H5N1-infected wild bird species reported in the World Animal Health Information System (WAHIS) database up to April 2024 [&lt;span&gt;3&lt;/span&gt;] and Scientific Committee on Antarctic Research up to November 2024 (SCAR) [&lt;span&gt;8&lt;/span&gt;], with species distributions primarily based on habitat maps (AOH) [&lt;span&gt;9&lt;/span&gt;] and, when these were lacking, bird ranges provided by BirdLife International [&lt;span&gt;10&lt;/span&gt;]. We removed records in which infected individuals were not identified at the species level and cases where individuals were kept in captivity. We obtained 345 unique wild bird species found infected by H5N1. To map the risk of H5N1 infection (i.e., areas where species reported as infected are distributed), we used the Additive Benefit Function (ABF) in Zonation v.5 [&lt;span&gt;11&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;Our risk map shows that Oceania presents a low risk compared with other regions, because it still does not host many species already reported as infected in the rest of the world (Figure 1A). However, more than 50 species that live in Oceania have already been infected in other regions (Table S1). Many of those species overlap their distributions in most of the coast of Australia and New Zealand, making this region of high risk (Figure 1B). Some key susceptible species reported infected in other regions (e.g., Antarctica and sub-Antarctic islands) such as Brown skuas (&lt;i&gt;Stercorarius antarcticus&lt;/i","PeriodicalId":13544,"journal":{"name":"Influenza and Other Respiratory Viruses","volume":"18 12","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/irv.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142835459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
