A literature search across key databases targeted studies from January 2023 to August 2024, emphasizing recent insights into JN.1's spread and clinical impact.

Previously approved antivirals, including Paxlovid, Veklury, and Lagevrio, demonstrate effectiveness against JN.1, and current vaccines still protect against severe illness from this variant. However, vaccination rates remain low. Monitoring efforts include genomic assessments, wastewater surveillance, and digital tracking to contain the variant's spread.

This menace is intensified by the alarming increase in drug resistance, which limits the availability of effective antibiotics for bacterial respiratory infections. Consequently, there is an urgent demand for alternative therapeutic options. Phage therapy (PT) has re-emerged as a promising therapeutic approach and as an adjunct to antibiotic treatment.</p><p><strong>Objective: </strong>This systematic review synthesises the application of PT for LRTIs in humans, providing unified and updated data on the evaluation of the safety and efficacy of PT for LRTIs.</p><p><strong>Design: </strong>Systematic review.</p><p><strong>Data sources and methods: </strong>Following the PRISMA guidelines, a comprehensive search strategy was carried out (spanning January 2000 - February 2024) in four databases: PubMed, Scopus, ScienceDirect and Web of Science to retrieve published records of PT for LRTIs in humans only. The reference list of each included study was evaluated for possible inclusion of other relevant articles.</p><p><strong>Results: </strong>Among the 18 records that fulfilled the inclusion criteria, 70 patients were administered PT. Microbiologically, 71.42% (<i>n</i> = 50/70) of the patients improved; with either the eradication of the pathogen or a decrease in bacterial load, whilst 15.71% (<i>n</i> = 11/70) did not record any improvement.

However, there is a lack of uniform methodologies and protocols across different PT cases in the management of LRTIs. Consequently, there is a need for additional clinical studies to establish standardised pharmacokinetic elements and an overall protocol for PT. By doing so, we can fully unlock the potential of PT in effectively managing clinical bacterial infections, including LRTIs.</p>","PeriodicalId":46154,"journal":{"name":"Therapeutic Advances in Infectious Disease","volume":"12 ","pages":"20499361241307841"},"PeriodicalIF":3.8,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11760135/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143048142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
