A novel therapy for intractable chronic cough
Two cases of intractable chronic cough improved significantly with humidified high flow therapy (HHFT). The mechanisms by which HHFT improve intractable cough may include reducing airway dryness, inhibition of neutrophil inflammation and mucus obstruction, and splinting of the airways. HHFT significantly improved cough and health-related quality of life in two patients with interstitial lung disease. Further research is warranted to explore the role of domiciliary HHFT. AbstractTwo cases of intractable chronic cough improved significantly with humidified high flow therapy (HHFT). A 59-year-old woman with Primary Sjogren's disease and interstitial lung disease, was trialled on a Fisher and Paykel myAIRVO ™ system. She reported sustained benefits of uninterrupted sleep and increased socialization with tapering use of HHFT. A 67-year-old woman with idiopathic pulmonary fibrosis also benefited from the use of myAIRVO™. She had relentless cough with minimal movement, and nocturnal cough causing frag mented sleep. Her cough subsided considerably with continuous HHFT, but recurred without. Both patients reported significant reductions in the cough visual analogue scale. The mechanisms by which HHFT improve intractable cough may include reducing airway dryness, inhibition of neutrophil inflammatio n and mucus obstruction, and splinting of the airways. HHFT significantly improved cough and health-related quality of life in two patients with interstitial lung disease. Further resea...
