PERIPHERAL BLOOD ENDOTOXIN LEVELS ARE NOT ASSOCIATED WITH SMALL INTESTINAL BACTERIAL OVERGROWTH IN NONALCOHOLIC FATTY LIVER DISEASE WITHOUT CIRRHOSIS.

Serum endotoxin levels did not differ between patients with and without SIBO, nor did these levels change after antibacterial therapy, virtually ruling out the possibility that elevated endotoxinemia in non-cirrhotic patients with NAFLD is associated with SIBO. Presence of SIBO was associated with greater severity of ballooning degeneration on liver biopsy, but not with a significantly higher prevalence of NASH. Additional studies are needed to evaluate the reproducibility and importance of this finding in patients with NAFLD and SIBO.
