Influence of drugs with hyaluronidase activity on the survival of animals with a purulent-inflammatory process in the abdominal organs

Abstract

BACKGROUND: The optimization of the pharmacokinetics of antibiotics is an important aspect in improving the effectiveness of therapy for intra-abdominal infections. Thus, studying the survival of experimental animals with a simulated purulent-inflammatory process in abdominal organs using the combined use of antibacterial agents with endolymphatic agents is worthwhile. AIMS: To examine the effect of the co-administration of cefotaxime and hyaluronidase or bovgyaluronidase azoximer on the survival of mice with a purulent-inflammatory process of the abdominal organs. MATERIALS AND METHODS: The purulent-inflammatory process of the abdominal organs, which was simulated by the intraperitoneal administration of a lethal dose of Staphylococcus aureus microbial suspension to mice, was evaluated. Four study groups were formed, with 28 animals each. Group 1 did not receive treatment, group 2 was administered with cefotaxime, and groups 3 and 4 received antibiotics after preliminary administration of hyaluronidase or bovgialuronidase azoximer. For the statistical analysis of animal survival, the KaplanMeier multiple assessment method was used, and a univariate analysis using a log-rank test was employed to identify significant differences between the groups. RESULTS: During the study, a single injection of cefotaxime alone and in combination with other studied drugs promoted the survival of some mice with a simulated purulent-inflammatory process of the abdominal organs compared with the untreated group, and at the end of the experiment (day 7), 100% of the animals died. Moreover, the best results were achieved with the initial administration of hyaluronidase or bovhyaluronidase azoximer. Thus, on day 7 of observation, 70% of the animals in groups that received both an antibiotic and hyaluronidase or bovgyaluronidase azoximer survived. No statistically significant differences were found in the effect of these drugs on animal survival in the presence of an experimental purulent-inflammatory process. CONCLUSION: A single injection of cefotaxime alone or in combination with other studied drugs ensures the survival of some mice with a simulated purulent-inflammatory process of the abdominal cavity compared with the control group, in which 100% of the animals died by the end of the experiment (day 7). Moreover, the best results were achieved in groups initially administered with hyaluronidase or bovgialuronidase azoximer.
