Abstract Details

2015, Master of Sciences, Case Western Reserve University, Clinical Research.
Objective: Abnormalities in the prostacyclin pathway are involved in pathobiology of pulmonary arterial hypertension (PAH) and can be studied noninvasively by cutaneous treprostinil iontophoresis. Methods: Treprostinil iontophoresis was tested in 24 patients with idiopathic or heritable PAH and 25 age- and gender-matched controls, between 2/2013 and 2/2015. Results: The percentage change in perfusion units (PUs) with treprostinil iontophoresis was significantly reduced in IPAH patients compared with matched controls (median (interquartile range) 246 (96-605) versus 538 (381-1,035), p=0.004). The peak PUs were associated with NYHA functional class (R=-0.35, p=0.01), number of PAH therapies (R=0.48, p=0.02) and cardiac index (R=0.41, p=0.05, respectively). Lower peak PUs related to increased oxidative stress and arginine methylation products in plasma. Conclusion: Patients with IPAH have a decrease in the cutaneous microvascular response to treprostinil iontophoresis compared with matched controls; a finding that can be due to increased oxidative stress and abnormalities of the nitric oxide pathway.
