Small intestinal bacterial overgrowth and endotoxinemia in patients with chronic liver disease / 中华消化杂志

ABSTRACT

Objective To study the correlation between small intestinal bacterial overgrowth (SIBO) and plasma endotoxin,platelet-derived growth factor(PDGF)level,and levels of serum hyaluronic acid (HA),laminin(LN),N-terminal procollagen Ⅲ peptide(PⅢNP)and type Ⅳ collagen(Ⅳ.C). Methods Lactulose hydrogen breath test (LHBT) was performed in 64 patients with chronic liver disease. Plasma endotoxin was measured with Limulus test, plasma PDGF was tested with ABC-enzyme-linked immunosorbent assay,serum HA,LN,PⅢNP and Ⅳ.C were tested by radioimmunoassay(RIA) in the patients. The relationship between SIBO and plasma endotoxin, PDGF and HA,LN,PⅢNP and Ⅳ.C levels were analyzed. Results Positive LHBT suggesting the existence of SIBO were observed in 22 patients(34.4%). Plasma endotoxin[(62?19) pg/ml vs.(31?13) pg/ml] and PDGF [(211?77) pg/ml vs.(136?57) pg/ml] levels were significantly higher in patients with SIBO than those in patients without SIBO (P
