Presence of human papillomavirus and Epstein-Barr virus in the cervix of women infected with the human immunodeficiency virus.

The presence of human papillomavirus (HPV) and Epstein-Barr virus (EBV) was sought in cervical scrapings from 110 human immunodeficiency virus (HIV)-infected women to evaluate the role of these viruses as risk factors for squamous intraepithelial lesions of the cervix. By using PCR, presence of HPV-DNA and EBV-DNA was found in 60.9% (67/110) and in 10% (11/110) of clinical samples, respectively. Identification of oncogenic group of HPV by hybrid capture (HC II, Murex-Digene) indicated the presence of low-risk HPV in 13 (19.4%) patients, high-risk HPV in 28 (41.8%), and both types of HPV in 26 (38.8%) patients. Squamous intraepithelial lesions were present in 59 cases, being low-grade (n = 52) and high-grade (n = 7) lesions. HPV was detected in 84.7% of patients with lesions, in association with low-grade (43/52) and high-grade lesions (7/7), and in 33% of patients without lesions. EBV-DNA was detected in 8 patients with low-grade lesions and in 3 patients without lesions. Concurrent genital HPV and EBV infection was observed in 9 cases. HPV was associated with detection of squamous intraepithelial lesions [OR = 3.55; 95% CI = (1.96; 6.48)]. No significant association was found between presence of EBV and detection of lesions, both in case of EBV infection alone [OR = 1.4; 95% CI = (0. 93; 2.12)] and in case of HPV/EBV combined infection [OR = 0.87; 95%CI = (0.54; 1.42)]. These data confirm the significant role of HPV as risk factor for squamous intraepithelial lesions and suggest that EBV could not be involved in the pathogenesis of the lesions that arise in the cervix of HIV-positive women.
