In fact 30%-50% of deaths in cirrhotic patients
is due to infections. Most commonly spontaneous
bacterial peritonitis (SBP) in ascites (25%-31%), urinary tract infection (25%-31%), pneumonia (15%-21%), bacteremia (12%) and soft tissue infection (11%).
Of course as with all things... the more advanced the degree of cirrhosis (compensated with portal hypertension, decompensated cirrhosis and End-Stage Liver Disease) the more dangerous infections can become.
