Bacterial Infection-Related Morbidity and Mortality in Cirrhosis

Leonidas Christou et al. Am J Gastroenterol.

Abstract

Objectives: Bacterial infections are acknowledged causes of morbidity and mortality in cirrhotic patients; yet, apart from spontaneous bacterial peritonitis, other infection issues have been understudied. We evaluated the existing medical data on infectious risks and related preventive and treatment data for cirrhotic patients.

Methods: Medical literature search through MEDLINE, using a variety of keywords focused on: (a) immunodeficiency parameters of cirrhosis and attempts at therapeutic reversal, (b) relative incidence of various focal infections and implications for prevention, and (c) specific pathogens posing a risk in cirrhosis and availability of preventive strategies.

Results: Immunodeficiency in cirrhosis is multifactorial and might not be reversed by isolated interventions. Epidemiologic data on the incidence of specific infections and risk factors are scarce, only Child-Pugh stage C being a common denominator. A variety of common, such as Staphylococcus aureus, Streptococcus pneumoniae, and Mycobacterium tuberculosis, as well as uncommon pathogens possess significant risks in cirrhosis. Certain aspects of these risks remain though unrecognized.

Conclusions: To better understand the overall burden of bacterial infections on cirrhotic patients' survival, more data on preventive efficacy of pneumococcal vaccination, on the overall burden of tuberculosis, and the relative incidence of specific infections as endocarditis are warranted.
