Cell-free DNA methylation-based inflammation score as a marker for hepatocellular carcinoma among people living with HIV.

Background: People living with the human immunodeficiency virus (HIV) are at a greater risk of developing hepatocellular carcinoma (HCC), potentially due to the stimulation of inflammation by HIV infection. Inflammation-related DNA methylation signatures obtained in liquid biopsy, such as circulating cell-free DNA (cfDNA), may serve as promising minimally invasive biomarkers that can inform diagnosis of HCC.

Methods: Using data from 249 individuals with HIV (114 individuals with normal liver conditions, 69 with fibrosis, 30 with cirrhosis, and 36 with HCC), we constructed a cfDNA methylation-based inflammation score (inflammation-DNAm score) based on 54 CpGs previously associated with circulating C-reactive protein concentrations.

Comparative Assessment of p16/Ki-67 Dual Staining Technology for cervical cancer screening in women living with HIV (COMPASS-DUST)-Study protocol.

The risk of progression of low-grade (CIN1) to high-grade cervical intraepithelial neoplasia (CIN2/3) is 3-5 times higher for women living with HIV (WLHIV) than for HIV-negative women. Evidence suggests that the current cervical cancer screening methods perform less effectively in WLHIV. An emerging screening method-p16/Ki-67 dual staining technology (DUST) is a safe and rapid assay that could be used to detect CIN2/3 with higher sensitivity and specificity.
