abstract
Cervical cancer is 5 times more likely among women living with human immunodeficiency virus (WHIV), likely due to higher prevalence of human papillomavirus (HPV). Despite evidence of higher rates with multiple HPV genotypes in WHIV, there are no recommendations for triage by HPV genotyping specific to WHIV. In Latin America/Caribbean rates are high and vary significantly. To guide optimization of HPV-based cervical cancer screening among WHIV in Latin America/Caribbean, review of current literature was completed to assess HPV genotype distribution by cervical disease grade in WHIV in this region; and further expanded globally for comparison across regions.A systematic review of the literature from June 2016 to January 2020 revealed 15 studies reporting human papillomavirus (HPV) genotype distribution by cervical disease state (normal, low-grade disease, high-grade disease, and invasive cervical cancer) across different global regions.Across all studies, there were 6928 WHIV from 4 global regions, 3952 of whom were HPV-positive. Three studies from Latin America/Caribbean (LAC) countries were reviewed, with 1 providing enough detail to describe HPV genotypes by cervical disease grade and identified types 31 and 35 in high-grade cervical lesions. Of the studies included, 4 from Africa and Europe/North America each, and 1 from Asia included data that were able to be summarized.Latin America, a region which experiences high rates of HPV, human immunodeficiency virus (HIV), and cervical disease, had few published studies reporting HPV genotypes by cervical disease grade, with 1 reporting individual HPV genotype and specific cervical disease grade. Identifying HPV types associated with CIN2+ in WHIV in this region has the potential to improve screening and treatment for cervical cancer prevention and should be the focus of future research.
