Comparison of different ratios of cefoperazone/sulbactam in patients with pyelonephritis.

ABSTRACT

Objective: To compare the clinical efficacy of different ratios of cefoperazone/sulbactam in the treatment of patients with pyelonephritis. Methods: In this retrospective study clinical records of patients with pyelonephritis treated in Huzhou Traditional Chinese Medicine Hospital from July 2020 to July 2021 were collected,. It included 55 patients who received cefoperazone/sulbactam 21 treatment (Control group) and 57 patients who received 1 cefoperazone/sulbactam 11 treatment (Observation group). Clinical response, inflammatory reaction and bacterial clearance were compared between the two groups. Results: The levels of C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-8 (IL-8) and leukocyte count (WBC) in the observation group were lower than those in the control group (P<0.05). The total efficacy of the Observation-group was 92.98%, higher than 80.00% of the control group (P<0.05). Fifty-eight strains of bacteria were isolated from the Control-group and 59 strains from the Observation-group. The bacterial clearance rates were 65.52% (38/58) and 83.05% (49/59), respectively. The differences were statistically significant (P<0.05). Conclusions: The clinical efficacy of 11 ratio of cefoperazone/sulbactam in the treatment of patients with pyelonephritis was superior that of 21 ratio. This ratio allows to fully utilize the antibacterial effect of cefoperazone, with a significant decrease in inflammation markers and an improvement in bacterial clearance.
