Abstract:We sought to investigate differential metabolism in patients with systemic sclerosis (SSc) who develop pulmonary arterial hypertension (PAH) versus those who do not, as a method of identifying potential disease biomarkers. In a nested case-control design, serum metabolites were assayed in SSc subjects who developed right heart catheterization-confirmed PAH (n=22) while under surveillance in a longitudinal cohort from Johns Hopkins, then compared to metabolites assayed in matched SSc patients who did not develo… Show more
