Background: Human papillomavirus (HPV) is the cause of 90%–95% of squamous cell cancers. Persistent infection with high-risk HPV can lead to development of precancerous lesions of the cervix in 5%–10% of infected women, and can progress to invasive cervical cancer 15–20 years later. This study was conducted to determine the seroprevalence of HPV immunoglobulin G (IgG) antibodies among women of reproductive age attending a reproductive health clinic at Ahmadu Bello University Teaching Hospital, Zaria, Nigeria.
Methods: The study was descriptive, cross-sectional, and experimental, combining the use of a structured questionnaire and analysis of serum samples obtained from 350 consecutive consenting women. The serum samples were analyzed for IgG antibodies to HPV by enzyme-linked immunosorbent assay.
Results: We found a seroprevalence of 42.9% (150/350) for IgG antibodies to HPV in these women. Women aged 45–49 years and those who had their sexual debut aged 20–23 years had the highest HPV seroprevalence, ie, 50% (57/114) and 51.1% (46/90), respectively. Presence of antibodies varied according to sociodemographic factors, but was significantly associated with educational status, tribe, and religion (P<0.05). Human papillomavirus infection was not significantly associated with the reproductive characteristics and sexual behavior of the women. Antibodies to HPV were detected in 50.0% (9/18) of women with a family history of cervical cancer and in 30.8% (4/13) of those with a history or signs of WHIM (warts, hypogammaglobulinemia, immunodeficiency, myelokathexis) syndrome as a genetic disorder (P>0.05).
Conclusion: Further studies are needed to determine the HPV serotypes and evaluate the risk of natural development of HPV-related malignancies among women in the study area.
