THE ROLE OF INTERFERON ALPHA-2b IN REDUCING OF VIRAL LOAD IN HPV INFECTED WOMEN
Abstract
Human papilloma virus (HPV) is the causal agent, necessary for the development of cervical cancer (CC). The International Agency for Research on Cancer (IARC) has classified 12 HPV types as group 1 carcinogens (oncogenic or high risk): HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59. Persistence HPV is associated with an increased risk of developing cervical squamous epithelial neoplasia (SIL) and СС. There is evidence that cell mediated immune responses of the host, both systemic and local, are important determinants of the course of infection . The use of interferon drugs in complex therapy of HPV infection can lead to reduction of viral load. The aim – to determine the frequency of different high risk types of HPV and to evaluate the effectiveness of the drug «Viferon» in reducing of viral load in HPV infected women. Materials and methods. The authors performed a prospective, randomized, placebo uncontrolled study. We have formed 2 groups among 60 women with HPV infection. The main group (n = 30) received rectal suppositories with interferon alfa-2b in dosage of 1000000 IU. In the comparison group (n = 30) treatment was not carried out. High-risk HPV DNA detection and viral load testing was performed by PCR. Results. Mono-infection was dominated among the patients of both groups the most common was HPV 16 (I – 28,6 %; II – 27,8 %). On the first visit, in group I was 3,5 ± 0,2 Lg (HPV/105 cells), in group II – 3,4 ± 0,3 Lg (p = 0,473). Viral load after 1 month was 1,9 ± 0,3 Lg (HPV/105 cells) and 2,8 ± 0,4 Lg, respectively (p = 0,04). In group I the viral load decreased by 45,5 %, in group II – by 18,3 % (p = 0,01). Conclusion. Mono-infection was prevalent among HPV infected women HPV 16 is the most frequently detected hrHPV. The use of the drug interferon alfa-2b in the study group, contributed to viral load reduction.
