ABSTRACT

Cirrhosis is an immunocompromised state that leads to various infections, with an estimated 30% mortality. Pakistan already has a high morbidity and mortality related to complications of cirrhosis. Where the data on infection among cirrhotics is scanty, this study aimed to determine the frequency, microbiological spectrum and various risk factors of infections in cirrhosis of liver. This is a prospective cohort study conducted at a tertiary care hospital. The microbiological spectrum and frequency of infections was determined in cirrhotics. Various risk factors for infection among cirrhotics were evaluated like upper gastrointestinal bleed, use of proton pump inhibitors, malnutrition and severity of cirrhosis. Out of eleven hundred and forty-one patients with cirrhosis of liver, four hundred and ninety (42.94%) patients had infections. All kinds of infections like peritoneal, respiratory, urinary tract and skin were present in cirrhosis of liver where ascitic fluid infections (AFI) were the commonest i.e. 44.89%. The risk factors for bacterial infections among patients with cirrhosis of liver were upper gastrointestinal bleeding (odd ratio = 4.57, p = 0.0001), use of proton pump inhibitors (odd ratio = 2.57, p = 0.0001), degree of malnutrition (odd ratio = 10.34, p = 0.0001) and severity of cirrhosis (odd ratio = 12.99, p = 0.000). All types of infections occurred with varying frequency in cirrhosis of liver. Upper gastrointestinal bleeding, severity of cirrhosis, use of high dose proton pump inhibitors and severe malnutrition are important risk factors for infections among cirrhotics.
