HEPATOLOGY, Vol. 41, No. 3, 2005 Most common infections in cirrhosis • spontaneous bacterial peritonitis (SBP) (25%) • urinary tract infection (20%), • pneumonia (15%) , • bacteremia (12%) • others Most common causative organisms Most common organisms isolated • Gramnegative bacteria (GNB) – E. Coli – Klesiella – Enterobacteriaceae species • Gram-positive cocci (GPC) – Pneumonia (mainly Streptococcus pneumoniae) – Bacteremia associated with invasive procedures (mainly staphylococci).

Journal of Infection (2009) 59(S1) S25 S31 Pneumonia • Community-acquired pneumonia still remains the most common type with Streptococcus pneumoniae • In alcoholic cirrhosis, infection with anaerobes, Hemophilus influenzae, and K.pneumoniae are of particular concern. • Hospital-acquired pneumonia is predominantly caused by gram-negative bacilli and staphylococci. • Third generation cephalosporins are generally recommended, with nosocomial pneumonia needing J Clin Gastroenterol 2007;41:403–411) Microorganisms Causing Pneumonia -- by Time After OLT* Aduen JF, Hellinger WC, Kramer DJ, et al.
