OBJECTIVE: The objective of the present study was to assess the prevalence and type-specific distribution of cervical high-risk (HR) human papillomavirus (HPV) among women with normal and abnormal cytology, and to describe risk factors for HR HPV among HIV-positive and HIV-negative women in Tanzania.

METHODOLOGY: A cross-sectional study was conducted in existing cervical cancer screening clinics in Kilimanjaro and Dar es Salaam. Cervical specimens were obtained from women aged 25-60 years. Samples were shipped to Denmark for cytological examination, and to Germany for HR HPV testing (using Hybrid Capture 2) and genotyping (using LiPaExtra). Risk factors associated with HPV were assessed by multivariable logistic regression analysis.

RESULT: Altogether, 4080 women were recruited with 3416 women contributing data for the present paper, including 609 HIV-positive women and 2807 HIV-negative women. The overall HR HPV prevalence was 18.9%, whereas the HR HPV prevalence in women with high-grade squamous intraepithelial lesions (HSILs) was 92.7%. Among HPV-positive women with HSIL, HPV16 (32.5%) and HPV58 (19.3%) were the the most common types followed by HPV18 (16.7%) and HPV52 (16.7%). Factors associated with HR HPV included younger age, increasing number of partners and early age at first intercourse. Similar risk factors were found among HIV-positive and HIV-negative women. In addition, among HIV-positive women, those with CD4 counts <200 cells/mm3 had an increased risk of HR HPV (OR 2.2; 95% CI 1.2 to 4.8) compared with individuals with CD4 count ≥500 cells/mm3.

CONCLUSION: Given the HPV distribution among Tanzanian women, the current HPV vaccination in Tanzania using quadrivalent vaccine may be considered replaced by the nonavalent vaccine in the future. In addition, appropriate antiretroviral treatment management including monitoring of viremia may decrease the burden of HR HPV in HIV-positive women.
