Genetically engineered PHOX2B rodents exhibit defective development of the brainstem retrotrapezoid nucleus (RTN), a carbon dioxide sensitive structure that critically controls expiratory muscle recruitment. This has been linked to a blunted exercise ventilatory response. Whether this can be extrapolated to human CCHS is unknown and represents the objective of this study.</p><p><strong>Materials and methods: </strong>Thirteen adult CCHS patients and 13 healthy participants performed an incremental symptom-limited cycle cardiopulmonary exercise test. Responses were analyzed using guideline approaches (ventilation V'_E, tidal volume V_T, breathing frequency, oxygen consumption, carbon dioxide production) complemented by a breathing pattern analysis (i.e. expiratory and inspiratory reserve volume, ERV and IRV).</p><p><strong>Results: </strong>A ventilatory response occurred in both study groups, as follows: V'_E and V_T increased in CCHS patients until 40 W and then decreased, which was not observed in the healthy participants (<i>p</i><0.001). In the latter, exercise-related ERV and IRV decreases attested to concomitant expiratory and inspiratory recruitment. In the CCHS patients, inspiratory recruitment occurred but there was no evidence of expiratory recruitment (absence of any ERV decrease, <i>p</i><0.001).</p><p><strong>Conclusions: </strong>Assuming a similar organization of respiratory rhythmogenesis in humans and rodents, the lack of exercise-related expiratory recruitment observed in our CCHS patients is compatible with a PHOX2B-related defect of a neural structure that would be analogous to the rodents' RTN. Provided corroboration, ERV recruitment could serve as a physiological outcome in studies aiming at correcting breathing control in CCHS.</p>","PeriodicalId":54237,"journal":{"name":"Pulmonology","volume":" ","pages":"2416790"},"PeriodicalIF":10.4,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139974560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to develop reference equations for spirometry and assess their applicability to residents at altitudes ranging from 2,100 to 4,700 metres above sea level. This extensive cross-sectional study encompassed healthy non-smokers aged 15 years or older living at Xinjiang and Tibet autonomous region, which covered eight high-altitude areas by a multistage stratified sampling procedure. All individuals underwent pre- and post-bronchodilator measurement. We used the Lambda-Mu-Sigma (LMS) method to establish reference equations for various spirometry parameters. We assessed model fit using mean absolute error (MAE), mean absolute percentage error (MAPE), and residual values (standard deviation), relative to established benchmarks such as GLI, ECSC, and NHANES III, to evaluate the applicability of our equations to high-altitude residents. Between June 2015 and August 2016, 3174 healthy subjects were included. The reference equations utilise age and height as independent variables, with improved accuracy achieved through spline functions. Our spirometry reference equations demonstrate minimal MAE, MAPE, and residual values (standard deviation) for most of the analysed spirometry parameters, stratified by gender.
