ABSTRACT
Background: In our multi-disciplinary airways service, we assess refractory breathlessness due to suspected inducible laryngeal obstruction (ILO) and/or breathing pattern disorder (BPD). A significant proportion of patients have evidence of uncontrolled co-morbidity, including rhinitis and asthma, which aggravate airway symptoms. Aim(s): To identify the impact of rhinitis management on i) nasal symptoms ii) asthma control and iii) cough control, for individuals referred with suspected ILO +/- BPD and evidence of rhinitis. Method(s): Patient demographics/clinical data were collected between January 2021 and January 2022. Symptoms were recorded using the Total Nasal Symptom Score (TNSS), Asthma Control Questionnaire (ACQ) in those with asthma and a 10-point self-rating scale in chronic refractory cough (CRC). Result(s): Data were available for 43 patients [72% female, 18% atopic, median (IQR) age 54 (41-64) years] with symptoms of rhinitis, confirmed by nasendoscopy in 41% (not all patients had nasendoscopy due to COVID-19 pandemic). Co-morbidities included asthma 54% (39%, of whom were on biologic treatment), CRC (21%), ILO (35%) and BPD (35%). Rhinitis management comprised education (100%), nasal corticosteroids (91%), saline nasal douche (49%) and antihistamines (10%). TNSS scores improved [from 5 (4-6) to 3 (2-4), p<0.001] following intervention. In those with asthma, there was improvement in ACQ [2.98 (2.15-3.70) to 2.00 (0.95-3.05), p<0.001], and in those with chronic refractory cough in self-rating score [8 (4-9) to 2 (2-6), p=0.11]. Conclusion(s): Optimisation of medical treatment for individuals with rhinitis is important and can improve outcomes in patients with asthma, CRC, ILO and BPD.
