Abstract
Bacterial infection is common and represents major cause of Morbidity and mortality in cirrhosise specially in the decompensated phase. Patients with cirrhosis are immuno-compromised and have an increased susceptibility to develop spontaneous bacterial infections, hospital-acquired infections, and a variety of infections from uncommon pathogens.
Moreover, bacterial infections have been acknowledged as a potential trigger factor in many complications of cirrhosis, including variceal bleeding, hepatic encephalopathy, renal failure and impairment in clotting factors.
Early identification of bacterial infections in patients with chronic liver disease is sometimes challenging. The clinical presentation is usually vague and atypical and the value of SIRS criteria for detection of sepsis is decreased Additionally the bacterial cultures require at least 24-48 hours for providing any results, thus delaying diagnosis and treatment Therefore the identification of other clinical and laboratory parameters would be of special interest in those patients.
Lately, inflammatory biomarkers such as CRP and PCT have been investigated as a tool for early diagnosis of bacterial infections in several clinical settings. Some studies have shown that CRP and PCT are reliable markers for diagnosis of bacterial infections in patients with chronic liver disease. However, their diagnostic accuracy and the cutoff values were highly variable.
The aim of this study was to evaluate the performance of CRP and PCT as markers for early diagnosis of bacterial infections in patients with end-stage liver disease and/or potential candidates for liver transplantation. To reach this aim, this case- control study has included 75 patients with dcompensated end stage liver disease, who were selected from ASCOT as well as from the Tropical medicine department Ain shams university.
The patients were then classified into three groups group A: was formed of 25 patients who were diagnosed as having chronic liver disease without confirmed bacterial infection (this group was designed to identify the effect of decompensated liver disease on the CRP value without the presence of bacterial infection), group B: (the control group): was formed of 25 patients, who were diagnosed as having end stage liver disease without confirmed bacterial infection (potential candidates for liver transplantation) and group C (the case group): was formed of 25 patients who were diagnosed as having end stage liver disease with confirmed bacterial infection).
