A significant reduction in peripheral CD14(+)CD16(+) monocytes by GMA should mitigate the inflammatory drive and contribute to the clinical efficacy of this procedure. Reduction of CD14(+)CD16(+) monocytes by corticosteroids was also seen. Hence, corticosteroids should enhance the efficacy of GMA. This is the first report on CD14(+)CD16(+) monocytes being decreased by Adacolumn GMA in patients with IBD.
We found strong correlations between CAI and IL-10 (r = 0.827, P < 0.001), IL-6 (r = 0.785, P < 0.001) and IL-18 (r = 0.791, P < 0.001). IL-1ra was not correlated with CAI. Following GMA therapy, 24 of the 31 patients achieved remission and the levels of all 4 cytokines fell to the levels in healthy controls. Further, blood levels of IL-1ra and IL-10 increased at the column outflow and inflow at 60 min suggesting release from leucocytes that adhered to the carriers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
