Urogenital pathogens such as and have been reported to cause pyuria, however they are not routinely cultured from urine samples of patients clinically diagnosed to have urinary tract infections (UTI). In this study, pathogen specific PCR was done to identify the urogenital pathogens in the urine samples among clinically diagnosed UTI patients with negative routine urine culture.
A cross-sectional study was conducted involving 227 archived urine samples from clinically diagnosed UTI patients with positive leucocyte esterase but negative urine culture results. The urogenital pathogens were detected using pathogen specific singleplex PCR. Data were cleaned and analyzed using STATA version 15.
The median age of patients was 31[IQR 23 - 51] years and the majority (174, 76.7%) were females. Two thirds of patients had history of antibiotic use two weeks prior to recruitment (154, 67.8%). A total of 62(27.3%) urine samples were positive for at least one urogenital pathogen. Of 62 positive samples, 9 had two urogenital pathogens and 1 had three urogenital pathogens. The most predominant urogenital pathogen detected was 25(34.2%) and 24(32.9%). Being female (aOR 2.4; 95% CI: 1.04 - 5.49; p-value 0.039) and having history of using antibiotics in the past two weeks (aOR 1.9; 95%CI: 1.04 - 3.60; p-value 0.036) was independently associated with the presence of urogenital pathogens.
More than a quarter of female patients with clinical symptoms of UTI and routine urine culture negative results were infected with urogenital pathogens mainly and . Further research with a larger sample set in a range of settings is required to understand the implications of these finding generally.
据报道,诸如[未提及具体病原体名称]等泌尿生殖系统病原体可导致脓尿,但在临床诊断为尿路感染(UTI)的患者尿液样本中,它们并非常规培养对象。在本研究中,采用病原体特异性聚合酶链反应(PCR)来鉴定临床诊断为UTI但常规尿液培养结果为阴性的患者尿液样本中的泌尿生殖系统病原体。
开展了一项横断面研究,纳入227份来自临床诊断为UTI且白细胞酯酶阳性但尿液培养结果阴性的患者的存档尿液样本。使用病原体特异性单重PCR检测泌尿生殖系统病原体。数据使用STATA 15版本进行清理和分析。
患者的中位年龄为31岁[四分位间距23 - 51岁],大多数(174例,76.7%)为女性。三分之二的患者在入组前两周有抗生素使用史(154例,67.8%)。共有62份(27.3%)尿液样本至少对一种泌尿生殖系统病原体呈阳性反应。在62份阳性样本中,9份含有两种泌尿生殖系统病原体,1份含有三种泌尿生殖系统病原体。检测到的最主要泌尿生殖系统病原体是[未提及具体病原体名称]25份(34.2%)和[未提及具体病原体名称]24份(32.9%)。女性(调整后比值比2.4;95%置信区间:1.04 - 5.49;p值0.039)以及在过去两周有抗生素使用史(调整后比值比1.9;95%置信区间:1.04 - 3.60;p值0.036)与泌尿生殖系统病原体的存在独立相关。
超过四分之一有UTI临床症状且常规尿液培养结果为阴性的女性患者感染了泌尿生殖系统病原体,主要是[未提及具体病原体名称]和[未提及具体病原体名称]。需要在一系列环境中使用更大样本量进行进一步研究,以全面了解这些发现的影响。
