While evidence suggests that some comorbidities may directly influence the development or progression of IPF, or <i>vice versa</i>, whether these associations are causal or arise independently due to shared risk factors, such as ageing, smoking, lifestyle and genetic susceptibility, is still uncertain. Some comorbidities, such as metabolic syndromes, gastro-oesophageal reflux disease and obstructive sleep apnoea, precede the development of IPF. In contrast, others, such as pulmonary hypertension and lung cancer, often become apparent after IPF onset or during its progression. These timing patterns suggest a directional relationship in their associations. The issue is further complicated by the fact that patients often have multiple comorbidities, which may interact and exacerbate one another, creating a vicious cycle. To clarify these correlations, some studies have used causal inference methods (<i>e.g.</i> Mendelian randomisation) and exploration of underlying mechanisms; however, these efforts have not yet generated conclusive insights. In this review, we provide a general overview of the relationship between IPF and its comorbidities, emphasising the pathogenic mechanisms underlying each comorbidity, potential shared pathobiology with IPF and, when available, causal insights from Mendelian randomisation studies.</p>","PeriodicalId":12265,"journal":{"name":"European Respiratory Journal","volume":" ","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12095908/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143779508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbiome and resistome profiles were assessed in relation to clinical outcomes.RESULTSNext generation metagenomic sequencing reproduced differences between countries in microbial profiles previously shown by culture in the EMBARC study. Metagenomics provided enhanced detection for some bronchiectasis pathogens including P. aeruginosa, H. influenzae and S. pneumoniae. Three metagenomic microbial clusters dominated by the genera Pseudomonas, Streptococcus and Haemophilus demonstrated pan-European but variable distribution. Diverse resistomes, linked to underlying microbiomes, were identified across Europe, with significantly higher diversity of resistance gene determinants in Southern Europe. Resistome composition significantly differed between regions characterised by regionally contrasting multi-drug-resistant profiles. The EMBARC-BRIDGE cohort validated established bronchiectasis resistotypes: RT1 and RT2, which occur at varying frequency across regions.

As immunoglobulin (Ig)A is crucial to ensure adequate mucosal immunity, we explored whether IgA-related mucosal immunity is impaired in BOS.METHODSSixty LuTx recipients from the COLT cohort were retrospectively included. All participants were in stable condition within the first year post-transplant. At 3.5 years post-LuTx, 30 remained stable and 30 had developed BOS. Bronchoalveolar lavage fluid (BALF) and sera collected pre-transplant and at 6 (M6) and 12 months (M12) post-transplant were assessed for monomeric IgA, secretory (S)-IgA, secretory component (SC) and cytokine profiling. Second, bronchiolar polymeric Ig receptor (pIgR) expression and subepithelial IgA-producing B-cell numbers were compared across graft tissue samples from 54 LuTx recipients classified as stable, pre-BOS, BOS or end-stage BOS.RESULTSS-IgA levels in BALF decreased between M6 and M12 (p=0.0001) and were reduced in BOS patients at M12 (p=0.0018). Patients with lower S-IgA levels had higher infection rates. BOS patients exhibited elevated SC levels in serum (p<0.01).
