[Prevalence and risk factors for bacteriuria in patients with cirrhosis].
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.
