Analysis of the pathogenic microorganisms and drug treatment of acute pelvic inflammatory disease

Department of Gynecology and Obstetrics, the First Affiliated Hospital of Bengbu Medical College, Bengbu, Anhui 233004, China

摘要

摘要: 目的分析急性盆腔炎性疾病患者的致病微生物的特点、种类，抗生素的治疗情况以及致病微生物的耐药情况，希望可以帮助患者找到更合适的治疗方案。方法回顾性分析2019年1月—2021年1月于蚌埠医学院第一附属医院妇科就诊的100例患者的资料，基于分析结果，研究致病微生物的耐药情况。结果患者的致病因素包括不规则阴道出血、流产等；患者多出现发烧、腹痛、白带增多等症状。致病微生物中大肠杆菌与表皮葡萄球菌最为常见；患者均静脉应用抗生素治疗，患者在使用第三代头孢治疗后，体温以及白细胞恢复正常的时间更短(P < 0.05)。药敏实验表明青霉素类耐药率为56.3%，头孢类耐药率为23.8%；患者在应用致病微生物敏感和耐药的抗生素治疗时血液中白细胞数量比较差异有统计学意义(P < 0.05)。多次抗生素传代处理致病微生物实验结果表明致病微生物对不同种抗生素产生耐药性的时间有一定的差异，传代培养结束，抗生素抑制90%的致病微生物生长浓度提高至64倍。结论急性盆腔炎性疾病致病微生物种类较多，其中占主导地位的是大肠杆菌与表皮葡萄球菌；三代头孢治疗效果优于二代头孢；喹诺酮类和氨基糖甙类抗生素的耐药性更低，可作为临床用药的首选。致病微生物耐药产生的速度较快，具体的抗生素选取应参考细菌培养、药敏实验、临床医生的经验进行综合判断。

Abstract: Objective To investigate the types, characteristics, resistance and treatments of pathogenic microorganisms in patients with acute pelvic inflammatory disease, which will help patients to find an appropriate treatment plan. Methods From January 2019 to January 2021, a retrospective analysis was conducted on the data of 100 patients who visited the gynaecology department of the First Affiliated Hospital of Bengbu Medical College. Based on the results of the retrospective analysis, the drug resistance of pathogenic microorganisms was investigated. Results Many causes of the disease, including irregular vaginal bleeding, abortion. The main symptoms of the disease are fever, abdominal pain and increased vaginal discharge. Escherichia coli and Staphylococcus epidermidis were the most common pathogenic microorganisms detected in 100 patients. All patients were treated with intravenous antibiotics, and the temperature and white blood cell count returned to normal in a shorter time in patients treated with third-generation cephalosporins (P < 0.05). The drug sensitivity test showed that penicillin had been tested and the drug resistance rate was 56.3%. Cephalosporin had been tested and the drug resistance rate was 23.8%. There was a significant difference (P < 0.05) in the number of white blood cells in the blood when the patients were treated with susceptibility antibiotic compared to the resistant antibiotic. Moreover, the results of serial passage experiment to treat microorganisms showed that there was a clear difference in the time it took bacteria to develop resistance to different antibiotics. At the end of the passages, the concentration that inhibited the growth of 90% of the bacteria had increased 64-fold. Conclusion There are many pathogenic microorganisms in acute pelvic inflammatory disease, the predominant pathogens of acute pelvic inflammatory disease are Escherichia coli and Staphylococcus epidermidis. Moreover, third-generation cephalosporins are superior to second-generation cephalosporins in treating patients with antibiotics. In addition, there is less resistance to quinolones and aminoglycosides, which may be the first choice of clinical treatment. Furthermore, Pathogenic microorganism can easily develop resistance, highlighting the importance of the accuracy of empirical medication. Of course, the selection of specific antibiotics should be based on comprehensive identification of bacterial culture, drug sensitivity tests and clinician experiences.
