We evaluated the prevalence and the clinical relevance of bacterial and nonbacterial infections in predominantly alcoholic cirrhotic patients, admitted to an intermediate complexity hospital, and we also compared the clinical characteristics, laboratory and evolution of these patients with and without bacterial infection in a prospective study of cohort. A total of 211 consecutive admissions in 132 cirrhotic patients, between April 2004 and July 2007, were included. The mean age was 51.8 (±8) years, being 84.8% male. The alcoholic etiology of cirrhosis was present in 95.4%. One hundred and twenty nine episodes of bacterial infections were diagnosed in 99/211 (46.9%) admissions, community- acquired in 79 (61.2%) and hospital-acquired in 50 (38.8%): spontaneous bacterial peritonitis (23.3%); urinary tract infection (21.7%); pneumonia (17.8%); infection of the skin and soft parts (17.1%), sepsis by spontaneous bacteremia (7.7%); other bacterial infections (12.4%). Gram-positive organisms were responsible for 52.2% of total bacterial infections documented cases. There were eight serious cases of tuberculosis, fungal and parasitic infections; the prevalence of tuberculosis was 6% with an annual mortality of 62.5%; 28.1% (9/32) of the coproparasitological examination had Strongyloides stercolaris. The in-hospital mortality was significantly higher in patients with bacterial infection than in non-infected patients (32.4% vs. 13.2%; p=0.02). The independent factors associated with mortality were bacterial infections, the score of Child-Pügh and creatininemia > 1.5 mg/dl. By the multivariate analysis, leukocytosis and hepatic encephalopathy degree III/IV were independent factors associated to bacterial infection. This study confirms that bacterial and nonbacterial infections are a frequent and severe complication in hospitalized cirrhotic patients, with an increase of in-hospital mortality.
