Outline
To analyze the clinical characteristics of patients infected with emphysematous pyelonephritis (EPN) and the drug resistance of the strains. To enhance the understanding of EPN, provide a basis for the selection of antibacterial drugs in clinical practice.
Evaluated 15 EPN patients’ clinical characteristics and outcome, analysis of pathogenic bacteria and drug resistance.
Among the 15 EPN patients, 66.67% (10 cases/15 cases) patients were cured, 13.33% (2 cases/15 cases) patients died, and 20.00% (3 cases/15 cases) patients were adverse. Fluid cultures identified 12 strains of pathogenic bacteria, with Escherichia coli being the most prevalent (66.67%, 8 cases/12 cases), followed by Klebsiella pneumoniae (25.00%, 3 cases/12 cases), and Pseudomonas aeruginosa was the least common (8.33%, 1 cases/12 cases), 75.00% (9 cases/12 cases) of the strains were multi-drug resistant. The drug sensitivity test results showed that amikacin, cefotetan, and cefoperazone sulbactam were 100.00% sensitive antibiotics; the sensitivity rates of meropenem, imipenem, and ertapenem were 91.67%.
Patients with EPN have high mortality and poor prognosis. Escherichia coli was the most common pathogenic bacteria, followed by Klebsiella pneumoniae, and the proportion of multi-drug resistant strains was high. We recommend the use of over 90% of the pathogen-sensitive drugs with susceptibility about 90% identified in this study.
