The interstitial lung diseases are a group of diseases in which patients develop uncontrolled scarring (called fibrosis) within the lung. This causes failure of the lung and patients become progressively more breathless over time. The commonest of these diseases is idiopathic pulmonary fibrosis and this is a devastating condition with a survival of 3-5 years.
Many people with fibrotic interstitial lung diseases have disrupted sleep as well as low oxygen levels at night or obstructive sleep apnoea (OSA - pauses in breathing at night time due to obstruction of the upper airway).
Patients with low oxygen levels at night have a worse quality of life, with fatigue during the day and survive for less long.
102 patients from specialist clinics at Guy's and St Thomas' and the Royal Brompton and Harefield NHS Foundation Trusts will be recruited. This research is funded by a grant from the British Lung Foundation. The investigators aim to compare patients with and without low oxygen levels at night by observing how their disease and quality of life changes over a year.
Patients will be asked to complete a two-night home sleep study which will involve wearing a probe over the finger connected to a sensor on the wrist. Patients will also be provided with a home spirometer to measure their breathing at home daily during the study.
Lung function testing (which is part of normal clinical practice), a six-minute walk test and quality of life questionnaires will be performed at the beginning of the study. These investigations will be repeated at six and twelve months and this will tell us how night time oxygen levels affect the progression of the disease, quality of life, exercise tolerance, hospitalisation frequency and survival of these patients.

|Estimated Study Completion Date :||May 30, 2021|
- Quality of life measured by King's Brief Interstitial Lung Disease Questionnaire (K-BILD) [ Time Frame: 0 months,12 months ]Change in K-BILD score from baseline at 12 months in patients with nocturnal hypoxaemia vs those without (defined as time spent with SpO2<90% of > 10% total sleep time)
- Forced vital capacity (FVC) [ Time Frame: 12 months ]Annualised decline in FVC in patients with nocturnal hypoxaemia vs those without
- Diffusion capacity of the lung for carbon monoxide (DLCO) [ Time Frame: 12 months ]Change in DLCO from baseline at 6 and 12 months in patients with nocturnal hypoxaemia vs those without
- Pittsburgh Sleep Quality Index (PSQI) [ Time Frame: 0 months, 6 months, 12 months ]PSQI score at baseline, and change at 6 and 12 months in patients with nocturnal hypoxaemia vs those without
- Insomnia Severity Index (ISI) [ Time Frame: 0 months, 6 months, 12 months ]ISI score at baseline, and change at 6 and 12 months in patients with nocturnal hypoxaemia vs those without
- Six-minute walk test (6MWT) [ Time Frame: 0 months 6 months, 12 months ]Total distance (in metres) and minimum oxygen saturation during 6MWT at baseline, 6 and 12 months
- Exacerbation frequency and hospitalisation [ Time Frame: 12 months ]
- Mortality [ Time Frame: 12 months ]
