Performance of visual Inspection With Acetic Acid for Cervical Cancer Screening as Compared to Human papillomavirus Deoxyribonucleic acid Testing Among Women With HIV in Ethiopia: A Comparative Cross-sectional Study

Objectives The aim of this study was to evaluate the performance of visual inspection with acetic acid compared with Human papillomavirus Deoxyribonucleic acid (HPV DNA) testing among women with HIV in Ethiopia. Methods A comparative cross-sectional study was conducted to address the aforementioned objective. Data were collected from January to October 2021, to compare the performance of these two screening modalities. Trained clinicians collected cervical specimens and immediately applied acetic acid for visual inspection. The HPV DNA testing was done using Abbott m2000rt/SP by trained laboratory professionals in accredited laboratories. A total of 578 women with HIV aged 25-49 years were included. Results Test positivity was 8.9% using visual inspection with acetic acid (VIA) and 23.3% using HPV DNA test. The sensitivity and specificity of the VIA test were 19.2% and 95.1%, respectively. The strength of agreement between the two screening methods was poor (k = .184). The burden of genetic distribution of high risk HPV16 was 6.1%, and HPV18 was 1.1%. Other high risk HPV types (ie non-HPV 16/18 high risk HPV genotypes) were predominant in this study (18.6%). Conclusion The higher positivity result using HPV DNA testing compared with VIA, and low sensitivity of VIA are indicating that the implementation of HPV DNA testing as the primary screening strategy is likely to reduce cervical cancer cases and deaths of women in the country.
