Clinical, functional, and radiological data were collected up to 28 months after hospital discharge.Among 715 patients hospitalized for COVID-19, 493 (69.0%) were discharged alive. We could access complete medical records for 268/493 patients (54.4%); 138/268 (51.5%) exhibited persistent respiratory symptoms and agreed with the data collection and follow-up. Patients were predominantly male (64.5%), with a mean (±sd) age of 58.9±15.3 years. At the last follow-up, the leading symptoms were asthenia (31.5%), dyspnoea (29.8%), and neuropsychological symptoms (17.7%). Lung function improved up to the last visit. Mean diffusing capacity of the lung for carbon monoxide (DLCO) was 77.8% of predicted value, total lung capacity (TLC) 83.5%, and O2desaturation during exercise (O2desaturation) −2.3%. While DLCO improved over the entire period, TLC improved in the early phase and O2desaturation in the late phase. Except for those with lung comorbidities, only one patient presented with minor functional and chest radiological alterations at 28-months.Patients with acute COVID-19 discharged alive showed improved clinical symptoms, lung function parameters and radiological signs up to 28 months post infection. Persistent symptoms consisted mainly of asthenia and dyspnoea, with lung function returning to normal. One patient without prior respiratory issues exhibited moderate pulmonary fibrosis.","PeriodicalId":11739,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140969760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to evaluate the association between pulmonary perfusion defects or residual vascular obstruction and functional recovery after PE.We performed a systematic review and meta-analysis including studies assessing both the presence of perfusion defects or residual vascular obstruction and functional recovery (i.e.persistent symptoms, quality of life, exercise endurance). An odds-ratio (OR) was pooled for perfusion defects or residual vascular obstruction and persistent symptoms using a random-effect model.12 studies were included totaling 1888 PE patients; at a median of 6 months after PE (range 2–72), 34% had perfusion defects or residual vascular obstruction and 37% reported persistent symptoms. Among patients with perfusion defects or residual vascular obstruction, 48% (95%CI 37–60, I2=82%) remained symptomatic during follow-up, compared to 34% (95%CI 20–51, I2=96%) of patients without such defects. Presence of perfusion defects or residual vascular obstruction was associated with persistent symptoms (OR 2.15, 95%CI 1.66–2.78; I2=0%, τ=0). Notably, there was no association between these defects and quality of life or cardiopulmonary exercise test parameters.While the odds of having persistent symptoms was higher in patients with perfusion defects or residual vascular obstruction after acute PE, a significant proportion of these patients reported no limitations. A possible causality between perfusion defects or residual vascular obstruction and residual functional limitation therefore remains to be proven.","PeriodicalId":11739,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140996218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that RLS-0071 inhibits a temporary neutrophil-mediated inflammation in the lungs induced by inhalation of low-dose LPS in healthy participants.Participants were randomised to one of three arms to receive inhaled LPS followed by three doses of either low-dose (10 mg·kg−1) or high-dose (120 mg·kg−1loading dose followed by 2 doses of 40 mg·kg−1) RLS-0071 IV or placebo (saline) every 8 h (Q8H). Biomarkers evaluating inflammatory responses, with absolute neutrophil counts in induced sputum as the primary endpoint, were collected before and at 6 and 24 h after LPS challenge.Active treatment with RLS-0071 showed a similar safety profile to participants receiving placebo. RLS-0071 significantly decreased the numbers of neutrophils in sputum at 6 h post LPS by approximately half (p=0.04). Neutrophil effectors myeloperoxidase, neutrophil elastase, and Interleukin-1β in sputum were also significantly decreased at 6 h for RLS-0071 compared with placebo. Several biomarkers showed trends suggesting sustained decreases for RLS-0071versusplacebo at 24 h.This clinical trial demonstrated that RLS-0071 was safe and well tolerated and modulated neutrophil-mediated inflammation in humans after inhaled LPS challenge, consistent with results from prior animal model studies.","PeriodicalId":11739,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140996972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
