In obstructive sleep apnoea (OSA), abnormal nocturnal BP patterns, particularly nondipping and nocturnal hypertension, are common and contribute to excess cardiovascular risk.

This narrative review summarises current evidence on the physiological regulation of nocturnal BP, the mechanisms by which OSA disrupts nocturnal BP control, the epidemiology and prognostic relevance of abnormal nocturnal BP patterns in OSA, and the effects of available therapies. Continuous positive airway pressure (CPAP) has the strongest evidence base and lowers nocturnal BP modestly on average, with greater effects in patients with uncontrolled or resistant hypertension and with better treatment adherence. By contrast, evidence for non-CPAP therapies, including mandibular advancement devices, supplemental oxygen, hypoglossal nerve stimulation and upper-airway surgery, remains limited and less consistent. In summary, nocturnal BP abnormalities are common, clinically important and frequently overlooked in OSA. Greater use of ambulatory BP monitoring and more precise identification of patients most likely to benefit from targeted treatment may improve cardiovascular risk stratification and management in OSA.</p>","PeriodicalId":12166,"journal":{"name":"European Respiratory Review","volume":"35 181","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13598623/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149029611","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}

Disruption of these pathways contributes to a broad spectrum of pulmonary diseases. In COPD, asthma, idiopathic pulmonary fibrosis, pulmonary arterial hypertension, infectious lung diseases, and lung cancer, iron dysregulation promotes oxidative stress, ferroptosis, inflammation, aberrant repair, vascular remodelling, or pathogen persistence.

Available therapies do not halt or reverse disease progression, and novel therapeutic strategies aimed at tissue repair are urgently awaited. To address this unmet need, ongoing research aims to provide insight into the cellular/molecular mechanisms underpinning defective lung repair in emphysema. Healthy lungs possess an intrinsic regenerative capacity based on alveolar epithelial progenitor cells that reside in their niche, which is composed of a supporting extracellular matrix, stromal cells and immune cells. While this stromal niche is vital for appropriate regenerative responses, emerging studies show that interactions within the stromal niche are defective in COPD, hampering alveolar repair. This review addresses the novel concept that restoring disrupted interactions within the diseased stromal niche may lead to repair of damaged lung tissue in COPD. The unavailability of successful strategies to achieve stromal health and support lung tissue repair may be due to an incomplete insight into the complex interactions within the alveolus. Moreover, inadequate delivery methods, with uncontrolled release and rapid clearance of regenerative compounds and therapeutic cells, contribute to the failed translation of novel findings into effective strategies. This review provides an overview of the current state of the field, including novel insights into the defective interactions that have been identified within the alveolar niche in COPD.

We then examined the various factors associated with SAD, focusing on SAD as defined by spirometry.Maximal mid-expiratory flow, especially below the lower limit of normal (LLN), appears to be the most accurate and reproducible spirometric measure to assess SAD. However, no gold-standard spirometric definition has been endorsed by respiratory academic societies, and forced expiratory volume in 3 s or 6 s <LLN or combined forced expiratory flow could be alternative criteria. Impulse oscillometry or computed tomography scanning represent possible alternative assessment methods, with limitations regarding reproducibility.Globally, prevalence of SAD varies between regions. Air pollution appears to be associated with a higher prevalence of SAD, particularly particulate matter with aerodynamic diameter <2.5 µm. Both active and passive smoking are associated with SAD. SAD is also strongly associated with COPD and the risk of developing it, making SAD a marker of accelerated decline in lung function. Several occupational exposures are associated with SAD, including exposure to organic and inorganic dust. A history of lung infections, especially tuberculosis, is also associated with SAD. Advanced age may also be an associated factor, although the association depends on the criteria used to define SAD. Cardiac events have been associated to SAD, which might explain the association between SAD and higher mortality risk.By integrating these different associations in clinical assessment, it would be possible to screen more reliably and preventively for SAD.

Differentiating physiological ageing from pathological trajectories is critical for diagnosis, prognostication and interpretation of clinical trial end-points, particularly in interstitial lung diseases where attenuation of forced vital capacity (FVC) decline is a primary outcome in most trials. Without a benchmark for expected ageing, it is difficult to determine whether therapy preserves lung function by preventing FVC loss or mirrors natural trajectories. We conducted a systematic review and meta-analysis of longitudinal evidence on age-related FVC changes among adults without lung disease. A search of major databases and conference proceedings identified 7160 citations; 50 publications representing 35 cohorts and over 365 000 participants met eligibility criteria. Follow-up ranged from three to 35 years, with three to 12 spirometric assessments per participant. Over five decades of research, a consistent pattern of decline after early adulthood was evident, but estimates varied widely (10-80 mL·year<sup>-1</sup>) due to heterogeneity in study design, population composition, outcome reporting and analytic approach. The strongest evidence came from an individual-level pooled analysis of over 30 000 participants, demonstrating that FVC peaks in the mid-20s, declines continuously without plateau and follows a linear trajectory in women (∼26 mL·year<sup>-1</sup>) and a biphasic trajectory in men (∼22 mL·year<sup>-1</sup> before age 40, ∼36 mL·year<sup>-1</sup> thereafter). These normative trajectories, averaging ∼20-30 mL annually, are essential for distinguishing healthy ageing from pathological decline.

Frailty, a multidimensional syndrome characterised by reduced physiological reserve and increased vulnerability to stressors, is highly prevalent among individuals with COPD and contributes to adverse outcomes. Both conditions share common biological mechanisms, including chronic inflammation, oxidative stress, endocrine dysregulation, mitochondrial dysfunction and skeletal muscle atrophy. Exercise acts as a physiological stressor that elicits hormetic responses, triggering favourable molecular adaptations such as enhanced mitochondrial biogenesis, improved redox balance and the upregulation of antioxidant and cellular repair pathways. These adaptations translate into improved muscle function, metabolic efficiency and immune homeostasis, thereby counteracting the catabolic processes that underlie both frailty and COPD progression. Scientific evidence supports the role of combined aerobic, resistance and balance training as the most effective approach to improving functional status and quality of life in frail individuals with COPD. Frailty in COPD represents a potentially reversible state of systemic vulnerability rooted in accelerated biological ageing. Exercise thus constitutes a powerful, multi-target intervention capable of reprogramming molecular ageing pathways and promoting resilience across organ systems. Integrating exercise physiology with the principles of geroscience offers a promising framework for personalised rehabilitation strategies aimed at extending health span in patients with COPD.
