Bacterial infections occur frequently in patients with cirrhosis and may worsen the disease outcome. We investigated the prevalence of bacteriuria in 500 consecutive patients with cirrhosis, in different Child-Pugh stages (41.4% A; 40.8% B; 17% C) and analysed the associated risk factors. Most of the cirrhosis cases were virus related; alcohol abuse was recorded in 6.2% of the patients. Bacteriuria was detected in 139 (27.8%) cases: 32.4% were more than 100,000 cfu/ml; 7.9% between 100,000 and 1.000,000 cfu/ml and the remaining cases more than 1000,000 cfu/ml. Escherichia coli was the most frequent isolated agent (84.5%); Proteus spp. strains were detected only in bacteriuria with more than 100,000 cfu/ml. At univariate analysis, female gender, age and presence of diabetes were significantly associated to bacteriuria, while Child-Pugh stage and the presence of hepatocellular carcinoma were not. In a multivariate model, only female gender and diabetes were significantly associated to bacteriuria. These results indicate that advanced cirrhosis was not a risk for bacteriuria, that was associated rather to gender and diabetes, which are common risk factors for bacteriuria in non-cirrhotic patients.

Abstract

Bacterial infections occur frequently in patients with cirrhosis and may worsen the disease outcome. We investigated the prevalence of bacteriuria in 500 consecutive patients with cirrhosis, in different Child-Pugh stages (41.4% A; 40.8% B; 17% C) and analysed the associated risk factors. Most of the cirrhosis cases were virus related; alcohol abuse was recorded in 6.2% of the patients. Bacteriuria was detected in 139 (27.8%) cases: 32.4% were more than 100,000 cfu/ml; 7.9% between 100,000 and 1.000,000 cfu/ml and the remaining cases more than 1000,000 cfu/ml. Escherichia coli was the most frequent isolated agent (84.5%); Proteus spp. strains were detected only in bacteriuria with more than 100,000 cfu/ml. At univariate analysis, female gender, age and presence of diabetes were significantly associated to bacteriuria, while Child-Pugh stage and the presence of hepatocellular carcinoma were not. In a multivariate model, only female gender and diabetes were significantly associated to bacteriuria. These results indicate that advanced cirrhosis was not a risk for bacteriuria, that was associated rather to gender and diabetes, which are common risk factors for bacteriuria in non-cirrhotic patients.
