Health providers often rely on trial-and-error approaches that may delay disease control, increase costs, and expose patients to unnecessary side effects. Biomarkers are key to precision asthma care, as they provide objective measures of underlying disease mechanisms. Established biomarkers such as blood eosinophil count, fractional exhaled nitric oxide, and serum total immunoglobulin E are important for identifying type 2-high asthma.

Emerging biomarkers, including proteomic, transcriptomic, metabolomic, and genomic biomarkers, show promise in further refining biologic therapy selection. In addition, digital biomarkers derived from electronic health records, wearable devices, and artificial intelligence-based algorithms offer new opportunities to capture real-world changes in disease and treatment response. Non-medical drivers of health, particularly socioeconomic factors, are increasingly recognized as modifiers of biologic effectiveness and may also be helpful in selecting biologic therapies.

The cohort was divided into two groups based on the presence of ILD to evaluate routine blood parameters and derived indices. Significant parameters from univariate analysis were further evaluated using two separate multivariable logistic regression models adjusted for age, gender, erythrocyte sedimentation rate (ESR), anti-Scl-70, immunosuppressive use, newly diagnosed status and monocyte-to-lymphocyte ratio (MLR).ResultsOut of 117 patients (mean age: 49.03 ± 13.48 years, 90.6% female), dcSSc-ILD was detected in 53% (n=62). Within the cohort, 42.7% (n=50) were receiving immunosuppressive therapy, and 35.0% (n=41) were newly diagnosed with dcSSc. Patients with dcSSc-ILD demonstrated significantly higher ESR (p=0.002), ESR-to-C-reactive protein ratio (ECR) (p=0.042), and ESR-to-lymphocyte ratio (SLR) (p=0.003) levels compared to those without ILD. Anti-Scl-70 positivity was observed in 39.3% of the cohort and was significantly more prevalent in the ILD group (50.0% vs. 27.3%, p=0.012). ROC curve analysis revealed an optimal ESR cut-off value of >23.5 mm/hour for identifying ILD, yielding a high specificity of 90.9% and a sensitivity of 43.5% (AUC: 0.667, 95% CI: 0.569-0.766, p=0.002). In multivariable regression analyses, the diagnostic value of ESR and anti-Scl-70 remained significant and independent after adjusting for age, gender, MLR and immunosuppressive therapy (Model 1), as well as new diagnosis status (Model 2). Each 1 mm/hour increase in ESR was associated with an approximately 7% increase in the probability of dcSSc-ILD.ConclusionESR and Anti-Scl-70 positivity serve as modest but highly specific independent indicators of lung involvement in dcSSc.

COPD is increasingly recognized as a heterogeneous disorder driven by coordinated immune dysregulation and airway structural remodeling; however, clinically applicable molecular signatures that capture these processes are still lacking.ObjectivesTo identify and validate a blood-based diagnostic signature for COPD and to explore the underlying immune and structural remodeling mechanisms.DesignA multi-stage integrative study combining retrospective bioinformatics analysis with prospective experimental validation.MethodsPublic lung transcriptomic datasets were used to identify COPD-associated candidate genes through differential expression, co-expression network, and machine-learning analyses. Candidate genes were validated by RT-qPCR in peripheral blood samples from stable COPD patients and healthy controls. Exploratory immune, single-cell, virtual perturbation, and molecular simulation analyses were performed to assess potential biological relevance.ResultsFour lung-derived candidate genes, AC079767.4, CEP55, EMR3, and ATP6V0D2, were identified. In peripheral blood validation, CEP55 and ATP6V0D2 showed the strongest diagnostic performance, whereas AC079767.4 showed limited blood-based discriminatory ability. Functional and immune analyses suggested that these genes may be associated with intracellular pH regulation, vesicular acidification, cytokinesis, immune imbalance, and inflammatory pathways. Single-cell analysis indicated that CEP55 was mainly enriched in epithelial, endothelial, and smooth muscle cells, whereas ATP6V0D2 was enriched in macrophages and monocytes. Virtual perturbation and molecular simulation analyses provided hypothesis-generating evidence for possible involvement in antigen presentation, T-helper-cell-related pathways, and ligand-target interactions.ConclusionThis study identified four lung-derived COPD-associated candidate genes through integrative transcriptomic, network, and machine-learning analyses. Among them, CEP55 and ATP6V0D2 showed the strongest peripheral-blood diagnostic performance and biological plausibility, supporting their prioritization as candidate circulating biomarkers for further validation. Exploratory docking and MD simulations suggested possible ligand-target interactions involving CEP55 and ATP6V0D2, but these computational findings require experimental pharmacological validation before any therapeutic relevance can be inferred.</p>","PeriodicalId":22884,"journal":{"name":"Therapeutic Advances in Respiratory Disease","volume":"20 ","pages":"17534666261478820"},"PeriodicalIF":3.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13500954/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148798064","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}
