A routine cell count from the ascitic fluid obtained either at diagnostic or therapeutic paracentesis should always be done to rule out SBP. Symptoms of Transferase SBP include abdominal pain, fever and vomiting. Diagnosis should also be suspected in patients with worsening of liver function, hepatic encephalopathy, renal failure and/or gastrointestinal bleeding but SBP is frequently asymptomatic. Previously, mortality exceeded 90% but with early diagnosis and current treatment strategies mortality has been reduced to approximately 20% [Garcia-Tsao, 2001; Tandon and Garcia-Tsao, 2008]. Inoculation of ascitic fluid in blood culture bottles often display Escherichia coli and Streptococcus species [Tandon and Garcia-Tsao, 2008], although ascites culture is negative in as many as 60% of patients, despite both clinical signs of SBP and neutrophil cell count >250 cells/?l. These patients should still be treated as having SBP [Rimola et al. 2000]. Treatment of SBP Since antibiotic resistance is an increasing challenge, ascitic fluid and blood inoculation + assessment regarding susceptibility to antibiotics prior to antibiotic treatment should always be performed. Empiric antibiotic treatment should be started immediately after diagnosis of SBP. Third generation cephalosporins such as cefotaxim cover most causative organisms and high throughput screening assay are often the treatment of choice [Felisart et al. 1985; Rimola et al. 1995]. Administration of 2 g intravenously twice a day is often preferred; a 5-day therapy is as effective as a 10-day therapy [Runyon et al. 1991]. Alternatively piperacillin/tazobactam could be considered [Novovic et al. 2012]. Patients with SBP and signs of hepatic dysfunction (bilirubin > 66 ?mol/l) or signs of renal impairment should further be given HA at 1.5 g albumin/kg in the first 6 hours followed by 1 g/kg on day 3 since HA infusion reduces the risk of HRS [Sort et al. 1999]. Furthermore, the beneficial effect of administering HA to the cirrhotic patient is probably also attributable to the albumin binding capacity of circulating pro-inflammatory and bacterial products such as prostaglandins (PGE2) and lipopolysaccharide. Consequently HA may Fasudil play an important role as modulator of the systemic and organ related inflammation evident in patients with decompensated cirrhosis [Arroyo et al. 2014; O��Brien et al. 2014]. The risk of re-infection is high and secondary prophylaxis with, for example, oral norfloxacin 400 mg daily, significantly reduces the risk of future SBP episodes [Gines et al. 1990]. Patients with low ascitic albumin concentration
