Chronic COUGH Management in Interstitial Lung DisEase

Interstitial Lung Disease (ILD) includes chronic, disabling and progressive respiratory conditions marked by lung inflammation and fibrosis. The quality of life and functionality of people with ILD is affected by a plethora of debilitating symptoms such as dyspnoea fatigue and cough. Among them, chronic cough (a cough lasting more than 8 weeks) reigns as one of the most prevalent and challenging, despite receiving far less attention from researchers than other symptoms. Chronic cough affects up to 8 out of 10 individuals with ILD and it is associated with a worse prognosis, mortality, and the need for lung transplantation. This condition showed a significant impact in people's life (e.g., urinary incontinence, speech interferences, depression, chest pain, couples sleeping in separate bedrooms, avoidance of public areas, reduced social interaction, and work absenteeism), further contributing to the decreased health-related quality of life experienced by this population. Managing chronic cough is, therefore, urgently needed. The general aim of this study is to explore the effects of a non-pharmacological cough control treatment on cough-related quality of life in people with ILD. The specific aims of this study are: i) to explore short- and mid-term effects of the non-pharmacological cough control treatment on cough related outcomes (e.g., cough frequency and intensity, dyspnoea, fatigue, cough self-efficacy, health-related quality of life and emotional status); ii) to identify (if any) adverse effects of this therapy.
