Abstract
Objective: The aim of this study was to investigate the distribution and drug resistance of pathogenic bacteria and the prognosis of patients with sepsis bloodstream infection with renal insufficiency. Methods: One hundred and twelve patients with septicemic bloodstream infection with renal insufficiency and 112 patients with septic bloodstream infection without renal insufficiency were selected as study group and control group, respectively. We compare the distribution of pathogenic bacteria, analyze the drug resistance of major bacteria, and compare the efficacy, the incidence of septic shock, duration of mechanical ventilation, hospitalization time, and duration of antimicrobial drug administration between the two groups. Results: A total of 140 pathogenic strains were isolated from blood cultures in the study group, and 136 strains were isolated from blood cultures in the control group. The sepsis bloodstream infection was mainly caused by Gram-negative bacteria, accounting for 59.42% (164/276). Among the gram-negative bacteria, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii had higher resistance rates to levofloxacin, ceftazidime, piperacillin sodium tazobactam, and amikacin. Among the gram-positive bacteria, Streptococcus pneumoniae, Enterococcus, and Staphylococcus aureus had high resistance rates to clindamycin, cefazolin, penicillin G, gentamicin, azithromycin, and levofloxacin. The rate of extended spectrum β-lactamase (ESBLs)-producing enterobacteria and multi-drug resistant Pseudomonas aeruginosa (MDR-PA) infection was significantly higher in the study group than in the control group; there was no difference in multi-drug resistant Acinetobacter baumannii (MDR-AB), vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA) between the two groups. The duration of hospitalization and the duration of antimicrobial drug administration were longer in the study group than in the control group. Conclusion: The pathogenic bacteria in patients with sepsis bloodstream infection with renal insufficiency are mainly Gram-negative bacteria, are more difficult to be cured, have a longer course of treatment, and need to use antibacterial drugs for a long time.
