Human papillomavirus prevalence in South African women and men according to age and human immunodeficiency virus status
BACKGROUND: Both cervical cancer and human immunodeficiency virus (HIV) are major public health problems in Sub-Saharan Africa. The objectives of the study were to investigate human papillomavirus (HPV) prevalence according to age, HIV status and gender. METHODS: Participants were 208 HIV-negative w...

description | BACKGROUND: Both cervical cancer and human immunodeficiency virus (HIV) are major public health problems in Sub-Saharan Africa. The objectives of the study were to investigate human papillomavirus (HPV) prevalence according to age, HIV status and gender. METHODS: Participants were 208 HIV-negative women, 278 HIV-positive women, 325 HIV-negative men and 161 HIV-positive men between the ages of 18–66 years. HPV types were determined in cervical and penile cells by Roche Linear Array HPV genotyping assay. RESULTS: HPV prevalence was 36.7 % (76/207; 95 % confidence intervals (CI): 30.4–43.4 %) in HIV-negative women, with the highest prevalence of 61.0 % (25/41; 95 % CI: 45.7–74.4 %) in women aged 18–25 years. HPV prevalence was 74.0 % (205/277; 95 % CI: 68.5–78.8 %) in HIV-positive women, with the highest prevalence of 86.4 % (38/44; 95 % CI: 72.9–94.0 %) in women aged 18–25 years. HPV prevalence was found to decrease with increasing age in HIV-negative women (P = 0.0007), but not in HIV-positive women (P = 0.898). HPV prevalence was 50.8 % (159/313; 95 % CI: 45.3–56.3 %) in HIV-negative men, with the highest prevalence of 77.0 % (27/35; 95 % CI: 60.7–88.2 %) in men aged 18–25 years. HPV prevalence was 76.6 % (121/158; 95 % CI: 69.2–82.9 %) in HIV-positive men, with the highest prevalence of 87.5 % (7/8; 95 % CI: 50.8–99.9 %) in men 18–25 years of age. HPV prevalence was found to decrease with increasing age in HIV-negative men (P = 0.004), but not in HIV-positive men (P = 0.385). HIV-positive women had a significantly higher prevalence of one or more HPV type(s) in the bivalent (HPV-16/18: 20 % 55/277, 9 % 12/207; P <0.001), quadrivalent (HPV-6/11/16/18: 26 % 71/277, 12 % 24/207; P = 0.001) and nonavalent vaccine (HPV-6/11/16/18/31/33/52/56/58: 65 % 181/277, 24 % 50/207; P <0.001) compared to HIV-negative women. Similar observation were observed in men for bivalent (20 % 32/158, 10 % 30/313; P = 0.001), quadrivalent (35 % 56/158, 13 % 41/313; P <0.001) and nonavalent vaccine (75 % 119/158, 28 % 87/313; P <0.001). CONCLUSIONS: This study demonstrated high HPV prevalence among HIV-positive women and men in all age groups. The high prevalence of HPV types found in bivalent, quadrivalent and nonavalent vaccines in South African HIV-positive and HIV-negative women and men demonstrate that this population will greatly benefit from current HPV vaccines. |
