We compared these cutoffs with studies of chronic pulmonary aspergillosis (CPA) and manufacturers' cutoffs.Eligibility criteriaOnly studies addressing the diagnostic value of <i>Aspergillus</i> IgG or precipitins for HP were included. Separately papers defining cutoffs for CPA were tabulated.Sources of evidencePublished papers were identified in literature searches in Embase, Web of Science, and Medline.ResultsWe identified 414 papers, of which 12 were included, all published between 1965 and 2005. Occupational HP linked to <i>Aspergillus</i> spp. exposure included Farmer's Lung, Malt-Worker's Lung, Esparto Worker's Lung, and Woodworker's lung (Sawmill-workers). No studies directly addressed serological testing in Tobacco Worker's lung, Compost Lung, or poultry workers. Among <i>Aspergillus</i> species exposure, <i>A. fumigatus</i> was most commonly described; others included <i>A. umbrosus</i> (now <i>A. glaucus</i>), <i>A. clavatus</i>, and <i>A. niger</i>. Antibody tests included ELISA, BALISA, precipitin tests and ImmunoCAP, with a higher sensitivity of ELISA and ImmunoCAP tests compared to precipitin tests. Patients with HP linked to <i>Aspergillus</i> exposures, were positive in 156/290 (53.8%) compared to 96/615 (15.6%) in those with similar occupational exposures without HP. In malt workers with HP 35/53 (66%) had detectable <i>A.</i> <i>clavatus</i> IgG antibody compared to 0/53 <i>A. fumigatus</i> IgG, and 13/74 (18%) exposed but unaffected workers, but are not commercially available.ConclusionsImproved means of establishing or ruling out <i>Aspergillus</i> exposure are required, given the negative consequences for patients of continued <i>Aspergillus</i> inhalation. Modern studies with commercially available <i>Aspergillus</i> IgG antibody assays are required to define appropriate cutoffs for HP, given numerous studies published for chronic pulmonary aspergillosis.</p>","PeriodicalId":10217,"journal":{"name":"Chronic Respiratory Disease","volume":"22 ","pages":"14799731251326592"},"PeriodicalIF":3.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12033569/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to develop a non-invasive machine learning model incorporating Peptest™ and GerdQ scores to facilitate GERC detection, particularly in primary care and resource-limited environments where MII-pH testing is not readily available.Methods210 chronic cough patients were enrolled between September 2022 and June 2024. GERC diagnosis followed established guidelines, and salivary pepsin levels were measured via Peptest™. Feature selection was performed using the Boruta algorithm (hereafter referred to as Boruta), a method based on random forest (RF), designed to identify relevant variables by comparing them to random shadow features. The selected optimal features were then evaluated using nine ML models, including logistic regression (LR), RF and others. Model performance was assessed through area under the curve (AUC), decision curve analysis (DCA), and calibration curves.Results73 (34.76%) patients had GERC. Peptest™ and GerdQ scores were key predictors. Logistic regression was selected for its balance of accuracy (AUC: 0.876) and clinical utility.

Adults with PRISm had more frequent respiratory symptoms, more comorbidities, greater health burden and poorer quality of life than those with normal spirometry. Pre- and post-bronchodilator FEV<sub>1</sub> and FVC were lower in adults with PRISm than those with airflow limitation. Adults with PRISm were less likely to use respiratory medicine than those with airflow limitation (OR = 0.56, 95% CI 0.38-0.81). <b>Conclusions:</b> PRISm was present in 11% of adults in this study and they had similar respiratory symptoms and health burden as adults with airflow limitation.</p>","PeriodicalId":10217,"journal":{"name":"Chronic Respiratory Disease","volume":"22 ","pages":"14799731241312687"},"PeriodicalIF":3.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11755527/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143022289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a cross-sectional study in which 60 adults with PTLD underwent a cardiopulmonary exercise test (CPET). Additionally, the following assessments were performed: spirometry, impulse oscillometry (IOS), chest X-ray (CXR), and QoL using the WHOQOL-BREF. The mean peak oxygen uptake (VO<sub>2peak</sub>) was 16.1 ± 6.8 ml/kg/min. There were positive correlations between VO<sub>2peak</sub> and several parameters, including height, physical-WHOQOL-BREF, and forced vital capacity (FVC). There were negative correlations between VO<sub>2peak</sub> and several parameters, including age, heterogeneity of resistance between 5 and 20 Hz, frequency response (Fres), and reactance-area. In IOS, patients with small airway disease (SAD) had a lower VO<sub>2peak</sub>. Regarding CXR, only cavitation and nodular opacities were associated with a lower VO<sub>2peak</sub>. In multivariate analysis, FVC, age, male sex, and Fres explained 65.2% of the variability in VO<sub>2peak</sub>. In conclusion, there is a relationship between VO<sub>2peak</sub> and lung mechanics in patients with PTLD. In these patients, IOS is able to detect more pulmonary mechanical alterations than spirometry, including those reflecting SAD. Thus, the use of both CPET and IOS may aid in the monitoring of patients with PTLD.</p>","PeriodicalId":10217,"journal":{"name":"Chronic Respiratory Disease","volume":"22 ","pages":"14799731251345492"},"PeriodicalIF":3.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12099090/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
