    Abstract:
    PURPOSE: Invasive cervical cancer (ICC) is associated in nearly 100% with persistent high-risk Human Papillomavirus (HR-HPV) infection. ICC is still one of the leading causes for cancer mortality in women worldwide. The immunosuppressive influence of Human Immunodeficiency Virus (HIV) and the immunocompromised period of pregnancy due to tolerance induction against the hemiallogeneic fetus, are generally risk factors for acquisition and persistence of HR-HPV infections and their progression to precancerous lesions and HPV-associated carcinoma. METHODS: Overall, 81 pregnant women living with HIV (WLWH) were included. A medical history questionnaire was used to record clinical and HIV data. Participants received cervicovaginal cytological smear, colposcopy and HPV testing. HPV test was performed using BSGP5+/6+ PCR with Luminex read-out. The HR-HPV genotypes 16, 18, 31, 33, 45, 52, 58 were additionally grouped together as high-high-risk HPV (HHR-HPV) for the purpose of risk-adapted analysis. RESULTS: HR-HPV prevalence was 45.7%. Multiple HPV infections were detected in 27.2% of participants, of whom all had at least one HR-HPV genotype included. HR-HPV16 and HR-HPV52 were the most prevalent genotypes and found when high squamous intraepithelial lesion (HSIL) was detected by cytology. HIV viral load of ≥ 50 copies/ml was associated with higher prevalence of HR-HPV infections. Whereas, CD4 T cells < 350/µl showed association with occurrence of multiple HPV infections. Time since HIV diagnosis seemed to impact HPV prevalence. CONCLUSION: Pregnant WLWH require particularly attentive and extended HPV-, colposcopical- and cytological screening, whereby clinical and HIV-related risk factors should be taken into account.
