Abstract
BACKGROUND Asthma and vocal cord dysfunction (VCD), also known as inducible laryngeal obstruction (ILO), may coexist, resulting in worse outcomes for patients. The experience of people with VCD/ILO and coexisting asthma is unknown. OBJECTIVE We sought to determine whether coexistent VCD/ILO and asthma have deleterious impacts on quality of life. METHODS We undertook a descriptive qualitative study using one-to-one semistructured interviews with 30 purposively recruited adult participants with a prior confirmed doctor asthma diagnosis and laryngoscopy-confirmed VCD/ILO. A thematic and content analysis was conducted to explore the data. RESULTS Participants were mostly female (63%), mean ± SD age 63 ± 12 years. Four themes were identified: trapped voice, altered life, knowledge about VCD/ILO, and looking for solutions. Participants reported their voice being trapped in their throat or the voice being suddenly cut off when talking or singing. Self-reported VCD/ILO symptoms including throat tightness and breathlessness were highlighted by participants. The second theme described how patients struggle to communicate or tended to shorten conversations. Insufficient knowledge and existing confusion regarding whether asthma was causing the breathlessness was described in the third theme. Looking for solutions depicted participants' diagnostic journey and how they sought an explanation for the symptoms. CONCLUSIONS People with asthma and coexisting VCD/ILO experience a substantial burden affecting the quality of life. These data describe the impact on patients with coexisting conditions and should be used to increase clinician awareness of the experience of VCD/ILO from patients' perspectives to support a personalized approach to care.

Abstract
OBJECTIVE Asthma is frequently accompanied by dysfunctional breathing of which hyperventilation has been recognized as a subtype. The prevalence of hyperventilation in stable asthma has been scantily studied using blood gas analysis. Hence, a reliable estimate of its prevalence is lacking. It is unknown whether the Nijmegen Questionnaire (NQ) is a useful screening tool for hyperventilation in asthma. Therefore, the primary aim of this study was to determine the prevalence of hyperventilation in a large sample of patients with asthma in a stable state of disease. Secondary aims were to compare the clinical characteristics between patients with and without hyperventilation, and, to examine the concurrent validity of the NQ to detect hypocapnia in patients with asthma. METHODS A real-world, observational, multicenter study was conducted. Capillary blood gas analysis was performed in adults with a confirmed diagnosis of stable asthma. A subset of patients completed the NQ. RESULTS A blood gas analysis was obtained in 1006 patients. In 17% of the patients an acute hyperventilation was found, and in another 23% a chronic hyperventilation was uncovered. Patients with a chronic hyperventilation blood gas were more often female, were younger and had a better spirometric outcomes. The NQ appeared not to correlate with PCO2. CONCLUSION Hyperventilation is common in patients with stable asthma. Chronic hyperventilation is more often found in females of younger age and with the best spirometric outcomes compared to patients without hyperventilation. The NQ is not a suitable screening tool for the presence of hyperventilation in stable asthmatics.
