Optimal Dose of Cefoperazone-Sulbactam for Acute Bacterial Infection in Patients with Chronic Kidney Disease

Abstract

The optimal dosage of cefoperazone-sulbactam for patients with chronic kidney disease (CKD) remains unclear. This study aimed to investigate two treatment strategies of cefoperazone-sulbactam–2 g/2 g twice daily and adjusted dose according to renal function for patients with CKD. A total of 155 patients with CKD received cefoperazone-sulbactam either at a dose of 2 g/2 g twice daily (study group) or adjusted according to renal function (control group) for the treatment of acute bacterial infection. The primary outcome was the clinical response rate at day 14 and the secondary outcomes included treatment failure and all-cause death. The study group had a higher clinical response rate (80.0% vs. 65.0%) and a lower treatment failure rate (4.0% vs. 23.8%) as compared with the control group. Further multivariable analysis showed that compared with the control group, the study group had a higher clinical response rate (adjusted OR = 4.02; 95% CI, 1.49–10.81) and lower treatment failure rate (adjusted OR = 0.06; 95% CI, 0.01–0.28). In addition, no significant difference in all-cause mortality was observed between the study and the control group (adjusted OR = 1.95; 95% CI, 0.57–6.66). Finally, no significant difference was observed between the study and the control group in the risk of the adverse events (AEs)–diarrhea (p = 0.326), eosinophilia (p = 1.000), prolonged PT (p = 0.674), alteration in renal function (p = 0.938) and leukopenia (n = 0.938). In conclusion, cefoperazone-sulbactam at a dose of 2 g/2 g twice daily could achieve better clinical efficacy than the reduced dosage regimen. Additionally, this dosage did not increase the risk of AE compared to the reduced dose. Therefore, cefoperazone-sulbactam at a dose of 2 g/2 g twice daily is an effective and safe regimen for acute bacterial infection in patients with CKD.
