Influence of IL-6, TNF-α and hs-CRP on Insulin Sensitivity in Patients after Laparoscopic Cholecystectomy or Open Hernia Repair

Abstract

SummaryBackgroundThe aim of this study was to investigate the influence of IL-6, TNF-α and hs-CRP on insulin sensitivity during postoperative follow-up in patients with laparoscopic cholecystectomy (LC) or open hernia repair (OHR).Methods65 patients were studied: after laparoscopic cholecystectomy (LC; n=40) or open hernia repair (OHR; n=25). Glucose, insulin, hs-CRP, IL-6 and TNF-a were determined at day 0 (before the operation) and at days 1, 3 and 7 (after the operation).ResultsThere were no difference between LC and OHR groups concerning age, BMI, glucose, insulin, hs-CRP, IL-6 and TNF-α at day 0. hs-CRP increased at day 1, 3 and 7 vs. day 0 (p<0.0005), without difference between groups (p=0.561). IL-6 increased at day 1 and day 3 vs. day 0 (p<0.005). IL-6 was higher at day 1 in OHR group in comparison with LC group (p=0.044). There were no differences in TNF-a levels between LC and OHR groups (p=0.056). There was increase of HOMA-IR at day 1, 3 and 7 vs. day 0 (p<0.0005) in both groups. Significantly higher increase of HOMA-IR was in OHR group compared with LC group at day 1 (p=0.045). There was a positive correlation between hs-CRP and HOMA-IR (r=0.46; p=0.025) and between IL-6 and HOMA-IR at day 1 in OHR group (r=0.44; p=0.030).ConclusionsSignificantly higher HOMA-IR was found in OHR group compared with LC. Positive correlation between hs-CRP and IL-6 with HOMA-IR in OHR group at day 1, indicate possible influence of this mediators on impairment of insulin sensitivity.

Intra‐individual association between C‐reactive protein and insulin administration in postoperative lumbar spinal canal stenosis patients: A retrospective cohort study

“…Intra‐individual correlation observed in the postoperative state might improve the current understanding regarding the association between CRP levels and insulin resistance. There are two potential explanations for our findings.…”

“…In particular, intra‐individual variability in insulin requirements and its association with CRP levels remains unclear. Although the postoperative correlation between CRP levels and insulin resistance was evaluated in a cohort study, intra‐individual variability was not considered.…”

Keratinocyte Growth Factor‐2 Reduces Inflammatory Response to Acute Lung Injury Induced by Oleic Acid in Rats by Regulating Key Proteins of the Wnt/β‐Catenin Signaling Pathway

“…At the same time, TNF-α can promote the release of a variety of inflammatory mediators and further expand the inflammatory response, thereby aggravating lung tissue damage [27,28]. TNF-α can also activate the blood coagulation system and complement system, so that the inflammation "cascades expansion" and spreads in the lung tissue [25,28,29]. IL-10 is an anti-inflammatory mediator, and its decrease indicates increased expression of inflammation [30,31].…”

Effects of preoperative oral enzyme-hydrolyzed rice flour solution on gastric emptying and insulin resistance in patients undergoing laparoscopic cholecystectomy: a prospective randomized controlled trial

“…Laparoscopic cholecystectomy (LC) is an effective treatment for gallbladder stones and cholecystitis. Although LC is a minimally invasive surgery with less trauma, it is also accompanied with stress response and postoperative IR [ 7 ]. POC has been proved to reduce IR in most types of surgery [ 8 , 9 ], however the effect of POC on LC remains controversial [ 10 , 11 ].…”
