Brief Summary:

Surgical resection is one of the curative treatment modalities for HCC. Limits are postoperative septic and liver functional complications related to an increase in bacterial translocation and systemic endotoxemia. Bacterial translocation is a passage of bacteria and bacterial degradation products from the intestine to the portal circulation. The endotoxemia secondary to bacterial translocation, stimulates endothelial production of nitric oxide (NO). NO is also a potent inducer of membrane instability, responsible for an increase in the permeability of the vascular endothelium and intestinal mucosa, possibly contributing to a worsening of bacterial translocation.

Probiotics are live microorganisms which when administered in adequate amounts, provide a health benefit on the host ((Health and Nutritional Properties of Probiotics in Food Including Powder Milk with Live Lactic Acid Bacteria - Cordoba Argentina October 2001). Data from experimental and clinical literature show a significant effect of probiotics on the improvement of liver function and a decrease in infectious complications in patients with chronic liver disease. The proposed study would evaluate the effect preventive and therapeutic in a population of surgical patients, in whom the intestinal portal and hepatic inflammation promotes postoperative complications.

Condition or disease Intervention/treatment Phase
Liver Fibrosis Liver Cirrhosis Permeability; Increased Hepatocellular Carcinoma Dietary Supplement: Probiotic Dietary Supplement: Placebo Not Applicable

Detailed Description:

The aim of this study is to evaluate the effect of the administration of probiotics on intestinal barrier function in patients with chronic liver disease (fibrosis stage F3 or F4) operated for hepatocellular carcinoma.

After hepatectomy, kinetic of endotoxemia have been studied previously and the evolution will be summarized by the area under the plasma concentration versus time curve (AUC) of circulating endotoxin levels measured before surgery and at 5 different times analysis after hepatectomy. At 12 hours, portal hypertension and its consequences on gut permeability (impaired barrier function, bacterial translocation) are highest with peak of circulating endotoxins. The decreasing of endotoxemia curve is observed between the 2nd and 3rd day (end of liver regeneration and early liver architectural reorganization). On the 5th day, persist measurable but not deleterious to liver restructured and theoretically functional rates.

Then the main criterion to demonstrate the effectiveness of a diet enriched with probiotics is the AUC of circulating levels of endotoxins ((pg/ml) using the Limulus amebocyte lysate (LAL) assay) observed for each patient. Endotoxin levels were analysed on samples of peripheral blood. The two arms of equal size will be considered significantly different when compared to the AUC of circulating levels of endotoxin if the null hypothesis (AUC is the same for both arms) is rejected in favor of the alternative hypothesis (AUC differs between the two arms - Wilcoxon test)

In order to estimate the sample size to distinguish between the two hypotheses with sufficient power, the median AUC in arm without probiotics be used to form two groups of patients in each arm. Thus, half of the patients without probiotics have a higher median AUC arms. Then, this proportion may be compared to the proportion of patients with probiotics have an AUC greater than the median of the group without probiotics.

The secondary endpoints are:

  • Evaluation of systemic inflammation by assay of inflammatory cytokines
  • IL-2, IL-4, IL-6, IL-8, IL-10, GM-CSF, IFNa, TNFa
  • CRP
  • Leukocyte count
  • The post-operative liver function monitored in the usual manner
  • Standard Liver function tests between J1 and J5 (Bilirubin, prothrombin, ammonia)
  • Indocyanine green clearance with measuring retention rates at 15 minutes between J1 and J3
  • Monitoring of overall postoperative complications and specifically liver failure and infectious complications at 3 months.
