Aim: To determine the associated risk factors and the laboratory parameters in spontaneous bacterial peritonitis (SBP).. Materials and methods-All patients of cirrhosis with ascites underwent diagnostic paracentesis within 24 h of admission or whenever peritonitis is suspected. SBP was diagnosed in the presence of a polymorphonuclear (PMN) cell count ≥ 250 cells/mm3 in peritoneal fluid. SBP was considered as community-acquired when diagnosed at admission or within 48 h of admission. Results- All the patients included in our study presented clinically with fever (100%) followed by pain abdomen (95%), abdomen distention (61.66%), encephalopathy (38.33%), reduced urine output (33.33%), jaundice (30%), Haemetemesis (10%) and malena (6.66%).The mean value of PMN cell count in ascetic fluid was 394.63 cells/mm3, total bilirubin was 4.47 mg/dL, Serum Creatinine was 1.53mg/dL, Serum albumin was 2.47 g/dL, INR was 1.85 and Serum sodium was 132.83 mEq/L. The mean values of MELD and iMELD score were 20.63 and 46.28 respectively. Conclusion- total bilirubin, serum creatinine, serum sodium, INR, MELD score and iMELD score were found as prognostic factors for prediction of mortality in patients with SBP.
