EVALUATION OF PROGNOSTIC FACTORS IN DECOMPENSATED LIVER CIRRHOSIS WITH ASCITES AND SPONTANEOUS BACTERIAL PERITONITIS

Mortality in spontaneous bacterial peritonitis (SBP) decreased significantly from 90% in 1970 to 10-30% today, but SBP still remains a complication with a poor prognosis. Although there are new preventive measures, such as early diagnosis and treatment with albumin, the introduction of new antibiotics, the prognosis of patients with decompensated cirrhosis and SBP remains poor, with a mortality rate of 20-40%. The installation of an episode of spontaneous bacterial peritonitis reduces the survival rate at 1 year to 30% and to 20% at 2 years. Purpose: In this context, the identification of patients with increased risk of death is extremely important in order to improve prognosis. Material and Methods: The prospective study included 153 patients with cirrhosis admitted to the Institute of Gastroenterology and Hepatology Iasi from 1 January to 31 December 2010, reevaluated during 2 years. Criteria for the diagnosis of SBP were the presence of a number> 250 PMN / mmc. The presence of ascites and / or upper gastrointestinal bleeding (UGB) marks the decompensated cirrhosis. To assess the severity of cirrhosis, there were used Child-Pugh and MELD scores. Diagnostic paracentesis and ascites fluid cultures were performed in all hospitalized patients with ascites and also in case of signs and symptoms of SBP, before and after antibiotic treatment. Lack of response to empirical therapy was considered in those cases with a decrease in the number of neutrophils <25% from baseline. Results: Identification of patients with increased risk of death is extremely important to improve prognosis. In peripheral leukocytosis and in the ascites fluid, low hemoglobin can be considered predictors of mortality in patients with PBS. Child-Pugh score, increased levels of bilirubin and creatinine and hyponatremia are independent risk factors of mortality in patients with SBP. Bacteremia and lack of therapeutic response are independent risk factors of mortality associated with SBP. Recent history of variceal bleeding, severity of infection and the degree of hepatic and renal impairment influence short-term prognosis of patients with SBP. Conclusions: Identification of patients with increased risk of death is extremely important to improve prognosis. Therefore, it is important to identify prognostic factors in patients with bacterial infection and cirrhosis, in order to identify high risk patients and to prevent complications and death.
