Interstitial lung disease in connective tissue disorders.

Abstract

Some of the most pressing challenges associated with interstitial lung disease (ILD) are how best to define, diagnose, and treat connective tissue disease-associated ILD (CTD-ILD)--disorders with potentially substantial morbidity and mortality. In this focused review, we address aspects of prognosis for CTD-ILD and what indices might predict outcome, together with lessons that can be learnt from clinical trials of systemic sclerosis-associated ILD and idiopathic pulmonary fibrosis and how these lessons might be applied to future studies of CTD-ILD.
