ADAR1 mRNA quantification for predicting HSIL in persons with HIV and abnormal anal cytology.

ABSTRACT: Anal squamous cell carcinoma is a significant concern among people with HIV (PWH), with high-grade squamous intraepithelial lesions (HSIL) as its precursor. Current screening, primarily based on abnormal anal cytology, often results in unnecessary high-resolution anoscopies (HRA) due to limited specificity. This study evaluates whether quantifying Adenosine Deaminase Acting on RNA-1 (ADAR1) mRNA in anal swabs improves HSIL prediction and optimizes HRA selection. In this prospective cohort, HIV-positive adults with abnormal anal cytology underwent HRA. ADAR1 mRNA levels were quantified from anal swabs, and human papillomavirus (HPV) genotyping was performed. The diagnostic performance of ADAR1 mRNA was assessed using receiver operating characteristic (ROC) curve analysis and compared with E
