Ureaplasma Species and Human Papillomavirus Coinfection and Associated Factors Among South African Adolescent Girls and Young Women

Ureaplasma species are associated with various reproductive health issues, while human papillomavirus (HPV) is associated with cervical, vaginal and vulvar cancers. Data on the association between Ureaplasma species and HPV are limited in South Africa. This study investigated the prevalence of Ureaplasma urealyticum (U. urealyticum), Ureaplasma parvum (U. parvum), and HPV coinfection and their associated factors, among adolescent girls and young women (AGYW) in the Eastern Cape Province, South Africa. A total of 214 partici-pants were retrospectively recruited, and secondary data on HPV, U. urealyticum, U. par-vum, demographics, and sexual behavior were used. HPV was detected using the Roche Linear Array HPV Genotyping Test, while U. urealyticum and U. parvum were detected us-ing Allplex™ sexually transmitted infection (STI) essential Assay. Statistical analyses were performed using GraphPad Prism Version 8.0.1.244. The prevalence of U. urealyticum was 43.9% (94/214) and increased significantly with age (p = 0.036, R2 = 0.8497); while U. parvum prevalence was 68.7% (147/214) and was not influenced by age. Having four to six lifetime sexual partners (PR:1.77, 95% CI: 1.04–3.00, p = 0.043) was associated with in-creased risk of U. urealyticum. A proportion of 36.3% (77/212) had HPV-U. urealyticum coinfection and its risk was increased among those with 3–6 lifetime sexual partners (PR: 1.59, 95% CI: 1.10–2.53, p = 0.017), 2–4 new partners past three months (PR: 2.14, 95% CI: 1.19–2.42, p = 0.021); vaginal sexual intercourse frequency past 1-month (2–3 vaginal in-tercourse: PR: 1.54, 95% CI: 1.06–2.53, p = 0.037; 4–10 vaginal intercourse: PR: 1.91, 95% CI: 1.83–1.91, p = 0.005) and alcohol consumption (PR: 1.85, 95% CI: 1.20–3.28, p = 0.004). U. urealyticum positives had a significantly higher risk of HPV types targeted by Cervarix® HPV vaccine than negatives (PR: 2.56, 95% CI: 1.23–5.37, p = 0.013), Gardasil®4 (PR: 2.16, 95% CI: 1.25–3.75, p = 0.006) and Gardasil®9 (PR: 1.70, 95% CI: 1.25–2.32, p = 0.001). AGYW of Eastern Cape Province, South Africa had high prevalence of U. urealyticum-HPV and U. parvum-HPV coinfections. Ureaplasma species coinfection was associated with HPV prevalence and distribution of genotypes. The U. urealyticum prevalence and its coinfection with HPV were associated with sexual behavior. Data from this study could contribute to the design of sexual health and STI interventions and could serve as a baseline for future epidemiological studies, which include ongoing surveillance of HPV genotype prevalence to evaluate the impact and effectiveness of HPV vaccination programs in the population.
