Abstract: Objective The aim of this study was to explore the correlation of blood cluster differentiation (CD) antigen 64 (CD64) index, serum soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and interleukin-6 (IL-6) levels to intestinal mucosal barrier functions in patients with hepatitis B liver cirrhosis (LC) and spontaneous bacterial peritonitis (SBP). Methods Eighty-six cirrhotics were admitted to our hospital between October 2015 and February 2020, and fifty-four had SBP. The peripheral blood CD64 positive polymorphonuclear neutrophils, lymphocytes and monocytes were detected by flow cytometry and CD64 index was calculated automatically. Serum sTREM-1 and IL-6 levels were detected by ELISA. Blood endotoxin (ETX) and urine lactulose/mannitol (L/M) ratio were detected and calculated to determine intestinal mucosal barrier functions. Results At presentation, serum IL-6, sTREM-1, D-Lac, DAO, EXT as well as blood CD64 index and urine L/M ratio in patients with SBP were(122.1±37.9)ng/L,(60.3±12.4)μg/mL, (5.1±1.6)μg/mL, (14.2±2.2)μg/mL, (0.2±0.0)U/mL as well as (12314.3±324.3)mol/cell and (0.2±0.1), all significantly higher than [(78.6±28.2)ng/L,(51.4±10.6)μg/mL,(2.5±0.8)μg/mL,(9.8±1.6)μg/mL,(0.1±0.0)U/mL as well as (6376.52.5±0.3)mol/cell and (0.1±0.0), respectively, all P<0.05] in LC patients without SBP; after treatment, serum IL-6, sTREM-1, D-Lac, DAO, EXT as well as CD64 index and urine L/M ratio in patients with SBP were (71.2±23.9)ng/L, (17.5±5.1)μg/mL, (2.9±0.8)μg/mL, (14.2±2.2)μg/mL, (0.1±0.0)U/mL as well as (3398.2±258.2)mol/cell and (0.1±0.0), also all significantly higher than[(52.1±21.6)ng/L,(10.8±2.5)μg/mL,(2.3±0.5)μg/mL,(8.7±1.2)μg/mL,(0.0±0.0)U/mL as well as (2541.0±266.2)mol/cell and (0.0±0.0), respectively, all P<0.05] in cirrhotics without SBP; after treatment, serum IL-6 and sTREM-1 levels as well as blood CD64 index in 33 SBP patients with disabled intestinal mucosal barrier functions were(75.2±24.1)pg/mL and (19.5±4.9)μg/mL as well as (3642.2±242.1)mol/cell, all significantly higher than [(65.2±21.3)pg/mL and (14.8±4.3)μg/mL as well as (3123.2±168.4)mol/cell, respectively, P<0.05] in 21 patients with normal intestinal mucosal barrier functions. Conclusion The LC patients with SBP have abnormal intestinal mucosal barrier functions, which might take part in the pathogenesis of bacterial translocation.
