Early markers of inflammation in a high angiotensin II state—results of studies in Bartter's/Gitelman's syndromes

摘要

Background. Inflammation has been increasingly recognized as playing a critical role in hypertension and atherosclerosis as reflected by overexpression and increased production of a variety of pro-inflammatory mediators. As angiotensin II (Ang II) also plays a major role in these diseases, the relationship between inflammation and Ang II has drawn increasing scrutiny. This study explores Ang II effects in Bartter's and Gitelman's syndromes (BS/GS) which do not develop hypertension and related cardiovascular remodelling and atherosclerosis, in spite of high Ang II levels and activation of the renin–angiotensin–aldosterone system while the NO system is up-regulated.
