Other Manifestations



  • Importance of Prompt Antibiotic Therapy
    • Delayed Antibiotic Therapy in SBP with Associated Septic Shock Significantly Increases the Mortality Rate (2015) [MEDLINE]
      • Study: retrospective cohort study from an international, multicenter database (n = 126)
      • Main Findings
        • SBP with associated septic shock carries an 81.8% in-hospital mortality rate
        • Each hour of delay in appropriate antimicrobial therapy is associated with a 1.86x increase in -inhospital mortality
        • The admission APACHE II score, admission MELD score, and admission serum lactate are all positively correlated with the in-hospital mortality rate
        • Earlier antibiotic initiation with appropriate antimicrobial therapy could significantly improve outcome

Albumin (see Albumin, [[Albumin]])

  • Clinical Efficacy

    • Trial of Albumin in Cirrhotics with SBP (NEJM, 1999) [MEDLINE]: in addition to antibiotics, intravenous albumin decreases the incidence of renal impairment and death, as compared to antibiotics alone

  • Dosing: albumin 1.5 g/kg of body weight at the time of diagnosis, followed by 1 g/kg on day 3
  • Clinical Efficacy: in combination with antibiotics, therapy, albumin as been demonstrated to decrease renal impairment and mortality rate [MEDLINE]
