We have read with interest the results of the study conducted by Solomon and colleagues, showing that addition of tumor necrosis factor inhibitor (TNFi) versus sulfasalazine and hydroxychloroquine on methotrexate regimen among individuals with rheumatoid arthritis (RA) did not result in a significantly greater reduction in arterial inflammation, measured as an arterial target-to-background ratio (TBR) in the carotid arteries and aorta.1 A closer look at participants' baseline characteristics revealed that a significant proportion of recruited patients (45.2%) had concomitant arterial hypertension.1 Renin-angiotensin system (RAS) blockers have been shown to exert at some extent anti-inflammatory effects,2 partially explaining the relatively low TBR among patients with established atherosclerotic cardiovascular disease, treated with angiotensin converting enzyme inhibitors.3 Similarly, in subjects with a recent acute coronary syndrome, treatment with an angiotensin-II receptor blocker resulted in a significant reduction in TBR over a 6 month period of treatment.4 Therefore, we strongly believe that a subgroup analysis of the primary endpoint according to baseline use of RAS blockers would provide useful additional insights into the interesting research hypothesis formulated by Solomon and colleagues.
