Postpartum women have relatively weaker bodies and may experience trauma during childbirth, providing opportunities for bacterial invasion. Therefore, there is indeed a certain risk of developing acute bacterial skin infections after childbirth. Postpartum acute bacterial skin infection can cause local or systemic symptoms, affect breastfeeding, and exacerbate the psychological and economic burden on patients.
This study aimed to analyse pathogen resistance in patients with acute postpartum bacterial skin infections and the differences of T lymphocytes and inflammatory factors.
In this case control study, a total of 100 patients with acute postpartum bacterial skin infections were selected as the experimental group. Another 100 healthy parturients were selected as the controls. The peripheral blood samples of the two groups were collected to detect the distribution of T lymphocyte subsets. The levels of inflammatory factors were detected. Separation and identification of pathogenic bacteria and drug sensitive test were performed in the experimental subjects.
The pathogens and drug resistance: Gram-positive bacteria such as Staphylococcus aureus and β-haemolytic Streptococcus were highly resistant to penicillin, erythromycin, clindamycin, and tetracycline, but sensitive to linezolid and vancomycin. Escherichia coli, Pseudomonas aeruginosa and other Gram-negative bacteria were highly resistant to amoxicillin, ampicillin, aztreonam, ceftriaxone, cefazolin, ciprofloxacin, and sensitive to imipenem. CD4+ and CD4+/CD8+ were markedly higher, and Th17/Treg was markedly lower in the controls compared to the experimental subjects ( < 0.05). IL-4, IL-10, and hs-CRP in the experimental subjects were higher compared to the controls ( < 0.05).
Staphylococcus aureus and Escherichia coli are the most common drug-resistant pathogens in patients with acute postpartum bacterial skin infections. The immune system plays an important regulatory role in the process of infection. T lymphocytes and inflammatory factors are differentially expressed in the process of infection.
产后女性身体相对较弱,分娩过程中可能会受到创伤,为细菌入侵提供了机会。因此,产后确实存在发生急性细菌性皮肤感染的一定风险。产后急性细菌性皮肤感染可引起局部或全身症状,影响母乳喂养,并加重患者的心理和经济负担。
本研究旨在分析产后急性细菌性皮肤感染患者的病原菌耐药情况以及T淋巴细胞和炎症因子的差异。
在本病例对照研究中,共选取100例产后急性细菌性皮肤感染患者作为实验组。另选取100例健康产妇作为对照组。采集两组外周血样本检测T淋巴细胞亚群分布。检测炎症因子水平。对实验组进行病原菌分离鉴定及药敏试验。
病原菌及耐药情况:金黄色葡萄球菌、β-溶血性链球菌等革兰阳性菌对青霉素、红霉素、克林霉素和四环素高度耐药,但对利奈唑胺和万古霉素敏感。大肠埃希菌、铜绿假单胞菌等革兰阴性菌对阿莫西林、氨苄西林、氨曲南、头孢曲松、头孢唑林、环丙沙星高度耐药,对亚胺培南敏感。与实验组相比,对照组CD4+及CD4+/CD8+明显升高,Th17/Treg明显降低(P<0.05)。实验组IL-4、IL-10及hs-CRP水平高于对照组(P<0.05)。
金黄色葡萄球菌和大肠埃希菌是产后急性细菌性皮肤感染患者最常见的耐药病原菌。免疫系统在感染过程中起重要调节作用。T淋巴细胞和炎症因子在感染过程中表达存在差异。
