BACKGROUND: Carbapenem-resistant Klebsiella pneumoniae (CRKP) infections in patients with cirrhosis represent a significant therapeutic challenge as they are associated with poor outcomes due to high rates of treatment failure, and frequently induce liver decompensation.
AIMS: To evaluate treatment failure and in-hospital mortality in two cohorts of patients with cirrhosis and with CRKP infections treated with antibiotic regimens including or excluding Ceftazidime-avibactam.
METHODS: Data from hospitalized patients with liver cirrhosis and CRKP infections were extracted and retrospectively analyzed.
RESULTS: During the study period, 39 cirrhotic patients with confirmed invasive CRKP infections were enrolled. Overall, the median age was 60 years with a median MELD score of 16 points. Urinary tract infections were diagnosed in 46%, followed by pneumonia in 23%, and primary bacteremia in 18% of patients. Treatment failure was reported in 10 patients (26%), while in-hospital mortality in 15 patients (38%). A monotherapy was used in 8 patients (20.5%), while a combination therapy was required in 31 patients (79.5%). Ceftazidime-avibactam therapy was associated with lower rates of treatment failure (7% vs. 38%, P = 0.032) independent of severity of liver disease (Child Class) and mono or combination antibiotic therapy. Acute kidney injury, hepatorenal syndrome, and acute-on-chronic liver failure were the consequences more frequently observed in patients with treatment failure. In-hospital mortality was associated with treatment failure, and Ceftazidime-avibactam therapy improved in-hospital survival (log rank test: P = 0.035) adjusted for Child class and mono or combination therapy.
CONCLUSION: Treatment including ceftazidime-avibactam was associated with a lower rate of treatment failure in cirrhotic patients with CRKP infections. Considering the favorable efficacy and outcomes of ceftazidime-avibactam, this drug should be considered for the treatment of these severe infections in patients with liver cirrhosis, though further investigation is required.
