Infection in cirrhosis: A prospective study

Abstract

Introduction and objectivesMultidrug-resistant (MDR) infections in cirrhosis are associated with poor outcomes. We attempted a prospective study on infections in patients with cirrhosis evaluating microbiology of these infections and how outcomes depended on factors like bacterial resistance, appropriate antibiotics, stage of liver disease and whether outcomes were significantly different from patients who did not have infections. Materials and methodsThis was a prospective evaluation involving one hundred and fifty nine patients with cirrhosis who were admitted at Peerless Hospitex Hospital and Research Center, Kolkata, West Bengal, India, during a 24 month period. One hundred and nineteen of these patients either had an infection at the time of admission or developed infection during hospitalization. Forty patients did not have an infection at admission and did not acquire infection while admitted. Data was collected about demographics, etiology of cirrhosis, liver and renal function and microbiology. ResultsInfections were community acquired in 27.7% of patients, healthcare associated in 52.9% and nosocomial in 19.3%. Gram negative bacilli (Escherichia coli 47.4% Klebsiella pneumoniae 23%) were common. 84.9% of enterobacteriaceae produced ESBL, AmpC or Carbapenemases. Spontaneous bacteria peritonitis (SBP) and urinary tract infection (UTI) were the most common sites of infection. In hospital mortality was 21.9%. Non-survivors had higher MELD (26 vs 19, p<0.001) and CTP scores (11.7 vs 10.3, p<0.001). The control group had lower MELD (16.65 vs. 20.8, p<0.001) and CTP scores (9.25 vs 10.59, p<0.001). ConclusionsMDR infections are common in patients with cirrhosis and have serious implications for treatment and outcomes.
