The serum concentration of interleukins (e.g., interleukin 6 or 18), high-sensitivity C-reactive protein (hs-CRP), or even simple, complete blood count-derived markers like neutrophil count, neutrophil-to-lymphocyte ratio (NLR), platelet count, platelet-to-lymphocyte ratio (PLR), and platelet volume (MPV) have been used in numerous studies as robust markers of subclinical inflammation in children and adults with primary hypertension [9,10,11,12]. This evidence concerns the gene CRP and essential hypertension.
