Ghrelin and Leptin Elevation in Postoperative Intra-Abdominal Sepsis

Abstract

During postoperative intra-abdominal sepsis, both ghrelin and leptin plasma levels are elevated and positively correlate with both inflammatory cytokines (TNF-alpha, IL-6) and main APP member (CRP). It supports experimental finding that TNF-alpha and IL-6 can be important regulatory factors of their synthesis. This hormonal reaction is not specific to sepsis--the significant increase of both ghrelin and leptin occurs during an uncomplicated postoperative response, although in a lesser extent than was shown in sepsis.
