Systemic sclerosis-related pulmonary hypertension associated with interstitial lung disease: impact of pulmonary arterial hypertension therapies.
Precapillary pulmonary hypertension (PH) is an important cause of death in patients with systemic sclerosis (SSc). It can occur in isolation (pulmonary arterial hypertension [PAH]) or in association with interstitial lung disease (ILD). Importantly, the outcomes and efficacy of PAH therapies in patients with SSc-related PH complicating ILD (PH-ILD) remain unknown. This study was undertaken to evaluate our experience with PH-ILD with regard to the efficacy and safety of PAH therapies in this patient cohort. ⋯ This study represents the largest series to date in which the impact of PAH therapies in SSc-related PH-ILD was examined. In this cohort, PAH therapies were associated with no clear benefits. Deterioration in oxygenation was an important determinant of long-term survival. Prospective clinical trials focusing on this group of patients are warranted.
