We aimed to compare the clinical antiviral effects of the two drugs.<h3>Methods</h3>In an open-label, phase 2, randomised, controlled, adaptive pharmacometric platform trial, low-risk adult outpatients aged 18–60 years with early symptomatic COVID-19 (<4 days of symptoms) were recruited from hospital acute respiratory infection clinics in Thailand and Laos. Patients were randomly assigned in blocks (block sizes depended on the number of interventions available) to one of eight treatment groups, including oral ensitrelvir and oral ritonavir-boosted nirmatrelvir at standard doses, both given for 5 days, and no study drug. The primary endpoint was the oropharyngeal SARS-CoV-2 viral clearance rate assessed between day 0 and day 5 in the modified intention-to-treat population (defined as patients with at least 2 days of follow-up). Patients had four oropharyngeal swabs taken on day 0 and two swabs taken daily from days 1 to 7, then on days 10 and 14. Viral clearance rates were derived under a Bayesian hierarchical linear model fitted to log<sub>10</sub> viral densities in standardised paired oropharyngeal swab eluates taken daily over the 5 days (14 samples). An individual patient data meta-analysis of all small molecule drugs evaluated in this platform trial using published results was also performed, adjusting for temporal trends in viral clearance.

Median estimated SARS-CoV-2 clearance half-lives were 5·9 h (IQR 4·0–8·6) with ensitrelvir, 5·2 h (3·8–6·6) with nirmatrelvir, and 11·6 h (8·1–14·5) with no study drug.

It is a primary arboviral infection with increasing global incidence, driven by climate change, urbanisation, and the expanding range of Aedes mosquito vectors. Despite growing research interest, outcome and measurement instrument heterogeneity in dengue clinical trials remains high, limiting comparability and evidence synthesis. This project aimed to develop a globally relevant Core Outcome Measurement Set (COMS) for use in dengue clinical trials through international consensus. This consensus study followed core outcome measures in effectiveness trials and Core Outcome Set-Standards for Development (COS-STAD) guidelines and was conducted in two phases. Phase 1 focused on developing a Core Outcome Set (COS) through four steps: (1) a systematic literature review; (2) qualitative interviews with people with lived experience of dengue; (3) review by the management group and steering committee; (4) a two-round modified Delphi survey and structured online consensus meetings to finalise the COS for hospitalised and early stages of dengue disease. Input from critical care experts informed recommendations for the intensive care unit (ICU) and high dependency unit COS. Phase 2 consisted of a further two steps: (1) targeted review of outcome measurement instruments; and (2) a hybrid international consensus workshop to finalise the COMS. The agreed COMS for hospitalised dengue included seven outcomes; the early stage dengue COS included these outcomes plus four more. For critical care trials, use of existing ICU-specific COS was recommended. Unified definitions were developed for nine clinician-reported outcomes. The DEN-CORE COMS provides a consensus-based framework for harmonising outcome selection and measurement in dengue trials, improving comparability and supporting policy and clinical decision making.","PeriodicalId":49923,"journal":{"name":"Lancet Infectious Diseases","volume":"56 1","pages":""},"PeriodicalIF":56.3,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145241705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additional microbiological testing in this context is often negative, but untreated individuals might still progress to culture-positive disease. We aimed to estimate the 2-year risk of tuberculosis among screened participants with trace-positive sputum (PWTS).<h3>Methods</h3>In this longitudinal follow-up study, we conducted Ultra-based systematic screening for tuberculosis in Kampala, Uganda, from Feb 2, 2021, to April 27, 2024, enrolling PWTS as well as participants who were Ultra-positive or Ultra-negative controls. Recruitment occurred primarily through community-based screening events and door-to-door screening. Ultra sputum testing was offered to individuals aged 15 years or older who were not on active tuberculosis treatment, regardless of their symptoms. All PWTS, as well as age-matched and sex-matched participants with negative screening results and consecutive participants with positive screening results, were recruited. Participants underwent extensive initial evaluation, and untreated PWTS and negative-control participants were followed up with re-testing for up to 24 months. Our primary outcome was the cumulative hazard of tuberculosis among PWTS, using two definitions of tuberculosis: one incorporating clinician judgement and one strictly microbiological. We then compared hazards between PWTS and negative-control participants. We also assessed whether the presence of symptoms or chest x-ray abnormalities at baseline were associated with tuberculosis diagnosis during follow-up in PWTS.<h3>Findings</h3>We screened 31 505 people for tuberculosis in Uganda using sputum Xpert Ultra as an initial test through event-based and door-to-door screening. We enrolled 128 PWTS and 139 age-matched and sex-matched control participants who were Ultra-negative (negative-control participants) into prospective cohorts and 110 control participants who were Ultra-positive (more than trace) for cross-sectional comparison. Of 128 PWTS, 79 (62%) were male, 49 (38%) were female, and 19 (15%) were HIV positive; 45 (35%) were recommended for treatment upon enrolment, eight (6%) were lost to follow-up within 3 months, and 75 (56%) were followed up for a median of 706 days (IQR 344–714), of whom 19 (25%) were recommended for treatment during follow-up. The cumulative hazard of tuberculosis among PWTS not treated at baseline was 0·24 (95% CI 0·15–0·40) at 1 year and 0·33 (0·21–0·54) at 2 years, versus 0·03 (0·01–0·10) at 2 years for negative-control participants.

AMR and antimicrobial consumption data on 13 new antibiotics were extracted by reviewing the literature and the reports from 38 surveillance systems included in the European Clinical Research Alliance on Infectious Diseases–The Epidemiology Network central data repository, encompassing 27 EU countries, four European Free Trade Association countries, and the UK. Our analysis revealed rapid resistance development to all new Gram-negative-targeting antibiotics, with particularly high ERI values for imipenem–relebactam and cefiderocol.
