【 摘 要 】

Abstract Background The presence of bacteremia as a complication of variceal bleeding in patients with liver cirrhosis had been investigated by many studies. The aim of this study was to assess the bacteremia as a risk factor for variceal upper gastrointestinal tract bleeding in cirrhotic patients. A cross-sectional study was conducted on 99 patients with chronic liver disease divided into three groups: group I included 35 patients presented with first attack of variceal bleeding, group II included 35 patients presented with recurrent attacks of variceal bleeding, and group III included 29 patients with no history of previous variceal bleeding as a control group. Routine laboratory tests were done, upper GI endoscopy, blood culture, and measurement of procalcitonin level in blood. Results Patients with recurrent variceal bleeding had statistically (p < 0.05) the highest percentage of positive blood culture followed by patients with first variceal bleeding and the control (60% vs 45.7% vs 24.1%) respectively. In addition to procalcitonin results, patients with recurrent variceal bleeding had statistically the highest values of PCT followed by patients with first variceal bleeding and the control (1.92 vs 0.325 vs 0.22 ng/ml) respectively. Multivariate regression analysis showed that procalcitonin and hemoglobin only was the significant predictors for variceal bleeding. Hemoglobin at cutoff value of ≤ 9.6 and procalcitonin (ng/dl) at cutoff value of > 1.76 is the most specific in predicting bleeding 86.21%, 86.21% (CI 95%) respectively. Conclusion Bacteremia and procalcitonin are risk factor for variceal bleeding in cirrhotic patients. Procalcitonin can be used as easily measurable and surrogate biomarker for bacteremia and variceal bleeding.
