统计数据收集:
所有参与者都经过临床医生的评估,签订知情同意书,通过使用一套预先测试的标准化问卷来收集数据。同时经患者许可,从医院病历中回顾性检索病史。在问卷中确定和评估了30多个变量。本论文从问卷中用到的数据仅有年龄,和实验室检查数据(帕氏涂片、冰醋酸实验,CD4计数,HPV基因分型,HIV-1血清学检测)。
受试人群平均年龄为37岁,在144例样品中,41例为HIV阳性,103例为HIV阴性。144例样本中有134例进行HPV实验和深度测序,87例HIV-HPV+,39例HIV+HPV+, 8例HIV-HPV-,无HIV+HPV-病例。
Among HIV samples, HPV had a statistically
significant effect (P 0.02) on the cervical microbiome (Fig. 1B and C). Those microbes
which were enriched in HPV samples were Bacteriodetes and fusobacteria. Also, there
was a decrease in Actinobacteria. Cervical cytology was determined to be negative for
intraepithelial lesion or malignancy (NILM) in 23 samples, low-grade squamous intraepithelial
lesions (LSIL) in 72 samples, and high-grade squamous intraepithelial lesions
(HSIL) in 50 samples. Visual inspection with acetic acid (VIA), the standard for cervical
lesion detection in Tanzania, was carried out immediately following sample collection.
Twenty-six patients were found to be VIA positive for cervical lesions and 115 were VIA
negative. All VIA-positive samples were identified as LSIL or HSIL, while several VIAnegative
samples were found to be NILM, LSIL, or HSIL by pap smear. Odds ratios were
used to identify risk factors for testing VIA positive. Testing HIV, HSIL, having 5
