Summary

Idiopathic pulmonary fibrosis (IPF) is a disease of unknown cause in which areas of normal lung tissue are replaced by scars. As a result it becomes harder for the lungs to extract oxygen from the air. IPF is commonly progressive, and around 50% of patients diagnosed with the disease die after approximately 3 years. The most common, troublesome symptoms of IPF are breathlessness on exertion, and cough. No drug treatments have been unequivocally shown to improve the death rate, or to significantly impact upon symptoms, in IPF.

In recent years it has been recognised that cough can be caused by small amounts of liquid coming up from the stomach and "going down the wrong way" into the lungs, a process commonly known as "reflux". As liquid in the stomach is usually acidic, patients' lungs may repeatedly be exposed to small amounts of acid. Reflux is unusually common in IPF and could potentially contribute to the debilitating cough found with the disease. However there are many potential causes for cough in IPF.

Stomach acid can be efficiently "switched off" by drugs called "proton pump inhibitors", one of which is called omeprazole. If reflux of stomach acid does contribute to cough in IPF, omeprazole might be expected to reduce cough. The purpose of this study is therefore to test whether omeprazole does reduce cough in patients with IPF. Sixty patients with IPF will be randomly allocated to have 3 months of omeprazole or a placebo. Neither the patient nor the doctor will be aware which treatment has been given, ie this is a randomised "double-blind", placebo--controlled trial. Patients' cough frequency will be measured before and after treatment and the change in cough frequency compared in those receiving omeprazole and those receiving placebo. Change in cough frequency is the main thing we aim to compare, but a range of other measurements will be assessed such as the numbers of patients eligible to take part, agreeing to randomisation and providing outcome data, patients' lung function, symptom scores, the amount of reflux, and the amount of inflammation in the lungs.
