INTERFERON IN THE TREATMENT OF WOMEN INFECTED WITH HIGH-RISK HUMAN PAPILLOMAVIRUS
Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide. About 99 % of cervical cancer is caused by persistent infection with high-risk types of HPV. It can take over 10 years from the time of an initial human papillomavirus infection until a cervical cancer. In most cases, HPV infections are transient and go away within 1 year. There is evidence that cell mediated immune responses of the host, both systemic and local, are important determinants of the course of infection, thus, it is reasonable to use immunocorrective therapy. Many studies have demonstrated the effectiveness of interferon alpha in complex therapy of HPV infection. The aim – to determine the efficacy of interferon alpha-2b in reducing the viral load of high-risk HPV among infected women of reproductive age. Materials and methods. 60 high-risk HPV positive women were included in the study. Qualitative and quantitative determination of high-risk HPV (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59) was carried out by PCR in real time. Patients were randomized into two groups: group 1 (n = 30) received alfa-interferon in the form of rectal suppositories; group 2 (n = 30) did not receive the drug. Control study was conducted 1 month later. The average age in group 1 was 31,7 ± 1,6 years, in group 2 – 35,0 ± 1,6 years (p = 0,08). In group 1 monoinfection diagnosed in 72,4 % of cases, mixed infection in 27,6 % of cases in group 2 – at 64,3 % and 35,7 %, respectively. Results. The average viral load was 3,5 ± 0,2 Lg (HPV on 105 cells) in group 1 and 3,4 ± 0,3 in group 2 (p = 0,473). Сlinically significant viral load dominated in group 1 (41,4 %), insignificant viral load was dominated in group 2 (42,9 %). After 1 month the average viral load was 1,9 ± 0,3 Lg (HPV on 105 cells) in group 1 and 2,8 ± 0,4 Lg in group 2 (р = 0,04). There were statistically significant difference in both groups before and after 1 month (p < 0,05). Elimination of HPV occurred in 34,5 % of cases in group 1 and at 28,6 % of cases in group 2. The viral load in the group that used interferon alfa-2b decreased by 45,5 %, in the comparison group only 18,3 % Conclusion. The treatment with interferon alfa-2b is effective in reducing viral load in HPV infected women of reproductive age. Long-term follow-up observation of this cohort is needed and further study of effective treatment regimens. Long- follow-up observation of this cohort is needed, in order to assess whether this regimen is effective.
