Understanding the determinants of health-related quality of life in rheumatoid arthritis-associated interstitial lung disease.

Rationale: Health-related quality of life (HRQL) is impaired among patients with interstitial lung disease (ILD). Little is understood about HRQL in specific subtypes of ILD.

Objectives: The aim of this study was to characterize and identify clinical determinants of HRQL among patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and compare them to patients with idiopathic pulmonary fibrosis (IPF).

Efficacy of pirfenidone in patients with idiopathic pulmonary fibrosis with more preserved lung function.

This post hoc analysis examined the differences in idiopathic pulmonary fibrosis disease progression and the effects of pirfenidone in patients stratified by more preserved versus less preserved baseline lung function status using forced vital capacity (FVC) or GAP (gender, age and physiology) index stage.Efficacy outcomes, i.e.

The need for patient-centred clinical research in idiopathic pulmonary fibrosis.

Patient-centredness is an accepted term and is perceived by healthcare professionals to be morally and ethically desirable. We are motivated by the belief that this approach will improve the patient-professional experience of the decision-making process and improve health outcomes. We acknowledge that patients, either as participants or as co-investigators, have positive contributions to make to research.
