Liver cirrhosis and Infections
Stage of liver cirrhosis
Severity of infections
• Liver cirrhosis is associated with defects in the
immune system, which increase the risk and
severity of infections.

Risk factors of infections in cirrhosis
-- invasive procedures
Reiner Wiest and Guadalupe Garcia-Tsao. 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).
Increasing causative organisms
--Fungal infection
• Candida
• Cryptococcus
• Aspergillus
• Coccidiodomycosis
Management of Infections
• SBP and other bacterial infections
• Fungal infections

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

Conclusions
• Infections in cirrhosis are a common cause of
morbidity and mortality;
• Abnormalities in cellular and humoral immunity and
the increasing use of invasive procedures predispose
these patients to a variety of infections.
• Clinicians should have a low index of suspicion as
prompt detection and the use of appropriate treatment
can improve survival in these patients.
Thank you!
