In systemic sclerosis (SSc) patients, pulmonary arterial hypertension (PAH), which is preceded by pulmonary vascular disease (PVD), is one the of major causes of morbidity and mortality. Given the higher risk of PAH among anti-CENP antibodies (ACA)+ patients, we previously characterised a subset of ACA+ patients, based on a differential reactivity of their ACA with the phage clone (pc4.2)-expressing peptide 4.2 (p4.2). There was a considerably greater prevalence of a low diffusing lung capacity for carbon monoxide (DLCO), an expression of PVD, among patients with high anti-pc4.2 Ab levels. Here we examine whether a similar clinical subgroup can be identified within a larger cohort of ACA+ patients, using the synthetic p4.2.

Abstract

In systemic sclerosis (SSc) patients, pulmonary arterial hypertension (PAH), which is preceded by pulmonary vascular disease (PVD), is one the of major causes of morbidity and mortality. Given the higher risk of PAH among anti-CENP antibodies (ACA)+ patients, we previously characterised a subset of ACA+ patients, based on a differential reactivity of their ACA with the phage clone (pc4.2)-expressing peptide 4.2 (p4.2). There was a considerably greater prevalence of a low diffusing lung capacity for carbon monoxide (DLCO), an expression of PVD, among patients with high anti-pc4.2 Ab levels. Here we examine whether a similar clinical subgroup can be identified within a larger cohort of ACA+ patients, using the synthetic p4.2.
