Urinary tract infections (UTIs) are extremely common, affecting people of all ages and health statuses. Although UTIs do not usually cause severe illness, in some cases they can lead to more serious complications, especially if their initial treatment is ineffective due to antimicrobial resistance (AMR). AMR is an increasing issue, exacerbated by misdiagnosis and inappropriate prescribing of antibiotics, thus facilitating further resistance. The aim of this study was to investigate the rates of AMR in isolated from clinical urine specimens tested at the Balfour Hospital, Orkney, and determine trends related to patient risk factors. Antibiotic susceptibilities were tested for 100 isolates of uropathogenic using the VITEK 2 Compact (bioMérieux), and data were analysed using percentage resistance rates. Resistance rates were compared by patient sex, age and source (hospital versus community). The findings showed higher AMR in males compared with females, particularly for trimethoprim (TMP), with 52% in males and only 12% in females. AMR tended to be higher in isolated from hospital inpatients than from community specimens, except for amoxicillin (AMX) and co-amoxiclav. Finally, the study found that AMR of isolates was greater in patients aged over 50 than 18-50 years old, particularly for AMX and TMP. The highest resistance rates across all patient demographics were for AMX, implying that the use of this antibiotic for the treatment of UTIs is not appropriate.
尿路感染(UTIs)极为常见,可影响各年龄段和健康状况的人群。尽管 UTI 通常不会导致严重疾病,但在某些情况下,它们可能会导致更严重的并发症,特别是如果由于抗菌药物耐药性(AMR)导致初始治疗无效的情况下。AMR 是一个日益严重的问题,误诊和不合理使用抗生素加剧了这一问题,从而进一步促进了耐药性的产生。本研究旨在调查在奥克尼的 Balfour 医院检测的临床尿液标本中分离出的 Uropathogenic 的 AMR 率,并确定与患者风险因素相关的趋势。使用 VITEK 2 Compact(bioMérieux)对 100 株尿路致病性 进行了抗生素药敏性测试,并使用耐药率百分比分析了数据。通过患者性别、年龄和来源(医院与社区)比较耐药率。研究结果表明,男性的 AMR 高于女性,尤其是对于甲氧苄啶(TMP),男性的耐药率为 52%,女性的耐药率仅为 12%。与社区标本相比,医院住院患者分离出的 的 AMR 往往更高,除了阿莫西林(AMX)和复方阿莫西林。最后,研究发现,年龄超过 50 岁的患者比 18-50 岁的患者分离出的 的 AMR 更高,尤其是对于 AMX 和 TMP。所有患者人群中,耐药率最高的是 AMX,这表明该抗生素不适合用于治疗 UTI。
