Abstract:Objective To evaluate the value of neutrophil CD64 in guiding the antibiotic therapy for hepatitis B liver cirrhosis complicated with spontaneous bacterial peritonitis (SBP). Methods Totally 134 patients with hepatitis B liver cirrhosis complicated with SBP were randomly divided into CD64 group (73 cases) and control group (61 cases). The patients in the CD64 group received antibiotics according to neutrophil CD64, and the patients in the control group were treated according to the clinical symptoms, the plasma level of white blood cell and antibiotic guidelines. The main observation indexes included duration of antibiotic therapy, cost of antibiotics, length of hospitalization, cost of hospitalization, Child-Pugh score, MELD score, clinical efficacy and mortality. Results The duration of antibiotic therapy and the length of hospitalization were shorter, the cost of antibiotics and the cost of hospitalization were lower in the CD64 group than in the control group (p < 0.05). There was no significant difference in the Child-Pugh score, the MELD score, the clinical efficacy or the mortality between the two groups after treatment (p > 0.05). Conclusions The neutrophil CD64 can be used as a reference index to guide clinical antibiotic application for hepatitis B liver cirrhosis complicated with SBP, and can shorten the duration of antibiotic use and length of hospitalization.
