Effects of the TNF-alpha Inhibiton on Hemodynamic Parameters in Resistant Hypertension

This crossover, double-blind study will include 12 resistant hypertensive subjects - regularly followed at the Outpatient Resistant Hypertension Clinic/UNICAMP - which will randomized assigned to (1) saline infusion followed by infliximab infusion (TNF-α inhibitor, 3 mg/kg) and (2) infliximab followed by saline, for two hours and washout of the 40-day period between both infusions. It is expected that the TNF-α inhibition regulates hemodynamic parameters, such as mean BP, cardiac Output, total peripheral resistance, which may allow a better rational approach for the RH treatment.
