Effects of Anti-TNF alpha Therapy on Blood Pressure in Resistant Hypertensive Subjects: A Randomized, Double-Blind, Placebo-Controlled Pilot Study.

Background: The cytokine tumor necrosis factor-alpha (TNF-α) is elevated in resistant hypertension (RH), but the effects of a TNF-α inhibitor in this population is unknown.

Objective: The aim of this trial was to evaluate whether a single dose of infliximab controlled by placebo acutely reduces blood pressure (BP) in RH subjects.

Methods: A double-blind, placebo-controlled, crossover trial was conducted, and randomized RH subjects received either infliximab or placebo.

Metabolic Syndrome-Related Features in Controlled and Resistant Hypertensive Subjects.

Background: Metabolic syndrome (MetS) is widespread among hypertensive patients. Clinical features and potential biomarkers of MetS in the presence of hypertension and resistant hypertension (RHTN) represent a great area of interest for investigation.

Objective: The purpose of this study was to evaluate the prevalence of MetS and the clinical features associated with it in resistant and mild to moderate hypertensives.

Acute Sildenafil Use Reduces 24-Hour Blood Pressure Levels in Patients With Resistant Hypertension: A Placebo-Controlled, Crossover Trial.

The authors previously demonstrated that acute administration of sildenafil-a phosphodiesterase 5 (PDE5) inhibitor-improves hemodynamic parameters in patients with resistant hypertensive (RH), but its effect on ambulatory blood pressure monitoring (ABPM) is unknown. This interventional, nonrandomized, single-blinded, placebo-controlled, crossover trial included 26 patients with RH. A dose of sildenafil (187.
