  • Clinical characteristics and prognosis of extensively drug-resistant Acinetobacter baumannii bacteremia

    Objective To summarize the clinical features and prognosis of extensively drug-resistant Acinetobacter baumannii (XDRAB) bacteremia. Methods This retrospective study included patients with Acinetobacter baumannii bacteremia diagnosed and treated in RICU of this hospital during January 1, 2012 and December 31, 2015. Demographic features, clinical data, clinical outcome within 3 days and 14 days after sample collection for blood culture were collected. Results Eight patients were included, with the mean age of (62.4±18.0) years, and including 3 males and 5 females. All patients had underlying diseases, 6 patients were immune suppressed, 7 patients had been exposed to β-lactam/enzyme inhibition or carbapenems for at least 7 days within 2 weeks before blood sample collection, and 6 patients received mechanical ventilation. Lung is the main pathogen source (6 cases). Within 48 hours after blood collection, the mean acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score was 28.3±7.5, the level of serum C-reactive protein (18.2 to 231.0 mg/L) and procalcitonin (0.1 to 25.0 ng/ml) had individual differences. The 3-day mortality rate was 4/8, the death group had APACHEⅡ >25. The 14-day mortality rate was 6/8, all the patients with procalcitionin>0.5 ng/ml died. Conclusions The 14-Day mortality is associated with the severity and increased procalcitionin in XDRAB patients. Preemptive therapy is recommend for patients with multiple risk factors, receiving mechanical ventilation, and with elevated procalcitonin and high APACHEⅡ score ( >25).
