systemic inflammatory response syndrome and meld score in hospital outcome of patients with liver cirrhosis

background the evidence saying that the rate of systemic inflammatory response syndrome (sirs) is high in patients with advanced cirrhosis and portal hypertension, this could have negative outcome on patients prognosis. methods this prospective study included 109 cirrhotic patients who were admitted to imam khomeini hospital, affiliated with orumieh university of medical sciences, during 2011-2012. the presence of sirs and the model for end stage liver disease (meld) were assessed on admission and during the hospital stay. sirs was considered positive if patients had two or more of the following: temperature of >38ºc or <36ºc; heart rate >90 beats/min; respiratory rate >20/min or paco 2 < 32 mmhg or the use of mechanical ventilation; wbc >12000/mm 3 or < 4000/mm 3 or more than 10% immature neutrophil count. meld was calculated as:  meld = 3.8 [ln serum bilirubin (mg/dl)] +11.2 [ln inr] +9.6 [ln serum creatinine (mg/dl)] +6.4. hospital outcome was defined as death or hospital discharge. results a total of 109 cirrhotic patients between the ages of 14 to 84 (mean: 54.6±18.4) years were included. there were 65 (59%) male patients. of the 109 patients, 76 (69.8%) were sirs-negative and 33 (30.2%) were sirs-positive. the mean calculated meld score for all patients was 15.5. there was a correlation noted between sirs and high serum creatinine levels ( p =0.01) and between sirs and a high meld score ( p =0.00). during follow-up 19 (17.4%) patients died. sirs was correlated  with death ( p˂ 0.00) on multivariate analysis, sirs was independently associated with hospital death.   conclusion sirs is a relatively frequent event in cirrhotic patients admitted to referral centers. it is closely related to the severity of liver disease as shown by the meld score. sirs independently and adversely affects the in-hospital outcome in patients with liver cirrhosis. normal 0 false false false en-us x-none fa
