and concomitant use of antimicrobial agents in case 2. Note. Intravenous piperacillin-tazobactam 4.5 gm iv q12h, daptomycin 250 mg iv q12h, and metronidazole 500 mg iv q8h were given from day 3 for empirical treatment of spontaneous bacterial peritonitis, while intravenous piperacillin-tazobactam 4.5 gm iv q12h, and daptomycin 250 mg iv q12h were given between day 45 and 56 for clinical diagnosis of another episode of spontaneous bacterial peritonitis.
