The use of cervical cancer screening strategies has largely improved the general outcome of cervical malignancies globally. Objective: To compare cervical cytological features against human papilloma virus genotypes in non HIV positive patients presenting for cervical cancer screening in UPTH. Method: A cross sectional prospective study of 82 non HIV positive women who presented for cervical cancer screening at the University of Port Harcourt Teaching hospital. A prestructured questionnaire was used to obtain socio demographic information. Cytobrush extracts of cervical samples were subjected to cytology and human papilloma virus DNA genotyping using real-time polymerase chain reaction. The information obtained was analyzed using SSPP version 20 and results presented as frequency tables, percentages and tested for significance using student t-test and chi square with p value Results: The mean age of the women was 36.61 ± 7.75 with an age range of 22 - 58 years. The prevalence of HrHPV was 4.88%. Twenty-two of the respondent have abnormal cytological pattern. While the 4 cases of HrHPV positivity were of normal cytological pattern and occurred in respondents that were in their reproductive age, the 22 that showed abnormal cervical cytology were mainly of low grade squamous intraepithelial lesion (LGSIL). There was no case of high grade squamous cell intraepithelial lesion (HGSIL). Conclusion: HrHPV prevalence rate of 4.88% occurring in low socioeconomic class patients. All the cervical abnormalies were of LGSIL, hence the risk of transformation into cervical cancer is equally low. There may be no correlation between hrHPV and cervical cytology in low risk patients.展开更多
目的对山东省女性高危型人乳头状瘤病毒(high-risk human papillomavirus,hrHPV)感染的检测结果进行分析,以了解山东省不同年龄和地区女性hrHPV的感染状况。方法采用新一代杂交捕获法,对济南金域医学检验中心2015年3月至2017年7月收集的...目的对山东省女性高危型人乳头状瘤病毒(high-risk human papillomavirus,hrHPV)感染的检测结果进行分析,以了解山东省不同年龄和地区女性hrHPV的感染状况。方法采用新一代杂交捕获法,对济南金域医学检验中心2015年3月至2017年7月收集的63 349例宫颈拭子标本,进行14种hrHPV检测(HPV16、18、31、33、35、39、45、51、52、56、58、59、66和68)。结果共检出hrHPV感染阳性者10 176例,阳性率为16.1%。不同年龄分布显示,总的hrHPV阳性率呈不对称双峰分布,以<25岁组最高(26.7%),随后的25岁～34岁组阳性率(16.3%)明显下降,35岁～44岁组(15.1%)最低,而45岁～54岁组和≥55岁组阳性率又略有升高,分别为15.5%和16.4%。不同地区阳性率比较,鲁西较高(22.8%),而鲁东(15.4%)和鲁中(15.0%)则较低;不同地区的年龄分布比较,除鲁东随着年龄增加而hrHPV阳性率逐渐下降外,其余地区与总的分布趋势一致。不同地区和总的hrHPV阳性女性病毒载量、不同年龄组间差异均无统计学意义。结论山东省不同年龄和地区女性hrHPV感染具有不同特点,这能够为本地区基于hrHPV的宫颈癌筛查,以及HPV疫苗接种提供一定的科学依据。展开更多
