Progression and mortality of interstitial lung disease in mixed connective tissue disease: a long-term observational nationwide cohort study

Abstract

Lung disease extent and progression in MCTD are modest. Yet, the extension continues several years after MCTD diagnosis causing lung function decline and increasing the risk of mortality. The study identified male gender, elevated anti-RNP titre, presence of anti-ro52 antibodies and absence of arthritis as the strongest predictors of ILD progression.
