Some antihypertensive drugs affect ACE2 expression or activity (ACE inhibitors and angiotensin II receptor blockers [ARBs]), suggesting use of other hypertensives might be preferable, such as calcium channel blockers (CCBs). Given the limited evidence, the International Society of Hypertension does not support such a policy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We used a Mendelian randomization study to obtain unconfounded associations of antihypertensives, instrumented by published genetic variants in genes regulating target proteins of these drugs, with immune (lymphocyte and neutrophil percentage) and inflammatory (tumour necrosis factor alpha [TNF\u2010\u03b1]) markers in the largest available genome\u2010wide association studies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Genetically predicted effects of ACE inhibitors increased lymphocyte percentage (0.78, 95% confidence interval [CI] 0.35, 1.22), decreased neutrophil percentage (\u22120.64, 95% CI \u22121.09, \u22120.20) and possibly lowered TNF\u2010\u03b1 (\u22124.92, 95% CI \u22128.50, \u22121.33). CCBs showed a similar pattern for immune function (lymphocyte percentage 0.21, 95% CI 0.05 to 0.36; neutrophil percentage \u22120.23, 95% CI \u22120.39 to \u22120.08) but had no effect on TNF\u2010\u03b1, as did potassium\u2010sparing diuretics and aldosterone antagonists, and vasodilator antihypertensives.
