“…An oxidative stress resulting from an increased production of ROS, however, is relatively common finding in INS [8,9] though SBP develops only on rare occasions [1][2][3]. From the clinical point of view, it is interesting that hypoalbuminemia in INS is associated with a higher risk of development of SBP [2,3] and that an intravenous administration of human albumin preparations to the patients with SBP caused by liver cirrhosis may be beneficial [4,5]. These findings suggest an oxidative stress not only due to increased ROS but also due to decreased BAP is contributed to the development of SBP because an albumin, of which decreased serum level is hallmark of relapsing INS, is well-known antioxidant in vivo [6]: albumin is able to scavenge various strong oxidants compounds, such as hydroxyl radicals, peroxynitrite, and hypochlorous acid.…”
