Semi-invasive \"endo-phenotyping\" sleep studies attribute this fall in AHI primarily to improved ventilatory control stability. Phenotyping Using Polysomnography (PUP) attempts to reproduce these studies using routine polysomnography (PSG). <b>Objectives:</b> To determine whether changes in AHI following CPAP associate primarily with changes in PUP-estimated ventilatory control stability (loop gain, LG<sub>1</sub>) or with changes in other PUP-estimated pathophysiologic mechanisms. <b>Methods:</b> PUP analyses were performed on existing PSGs in research participants who underwent baseline PSG, 4.4±2.2 months CPAP therapy, and CPAP withdrawal with repeat PSG on night 2 of withdrawal. Pre-CPAP PUP-estimated LG<sub>1</sub>, arousal threshold (ArTH), and upper airway collapsibility (Vpassive) and compensation (Vcomp) were compared to corresponding values during CPAP withdrawal. Mixed effects models were constructed to determine which PUP estimate best explained changes in AHI. <b>Results:</b> PSG data were available for 35 participants (age 47±10.8 years; 12 female; BMI 38.5±8.6 kg/m<sup>2</sup>, AHI3A 58.8±33.1 events/hr, 9 mild/moderate OSA, 26 severe OSA). Following CPAP, AHI decreased, but the change was not statistically significant.

Across all participants, changes in PUP estimates did not exceed test-retest agreement limits. For those with severe OSA, decrease in LG<sub>1</sub> (0.86 [0.61-1.13] pre-CPAP versus 0.71 [0.61-0.99] on CPAP withdrawal) and increase in Vpassive (64.8 [5.4-88.4] %Veupnea pre-CPAP versus 76.4 [20.7-92.7] %Veupnea on CPAP withdrawal) exceeded test-retest agreement limits. Increased Vpassive, decreased LG<sub>1</sub>, and decreased ArTH were predictors of decreased AHI in mixed effects models. Vpassive had the greatest estimated effect on AHI. After accounting for Vpassive, additional estimates did not improve model performance. However, Vpassive and LG<sub>1</sub> were correlated, and post hoc analyses suggest these estimates may be influenced by both upper airway collapsibility and ventilatory control. <b>Conclusions:</b> According to PUP physiologic estimates, decreases in AHI following several months of CPAP therapy are primarily attributable to improved upper airway collapsibility.</p>","PeriodicalId":93876,"journal":{"name":"Annals of the American Thoracic Society","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142585081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Across the Americas, COPD disproportionately affects vulnerable populations, including minoritized populations and impoverished persons, who are more likely to be exposed to risk factors such as tobacco use, air pollution, infections such as tuberculosis, and biomass smoke, but less likely to have adequate healthcare access. Management of COPD can be challenging across the Americas, with some barriers being specific to certain countries and others shared across the United States, Canada, and Latin America. Because most cases of COPD are undiagnosed because of suboptimal access to health care and pulmonary function testing and, thus, cannot be treated, increased access to spirometry would have a substantial impact on disease management across the Americas. For individuals who are diagnosed, access to medications and other interventions is quite variable across and within nations, even in those with universal healthcare systems, such as Canada and Brazil. This emphasizes the importance of collaborative treatment guidelines, which should be adapted for the healthcare systems and policies of each nation or region, as appropriate.
