Abstract/OtherAbstract:
OBJECTIVES: Langerhans cells play a pivotal role as professional antigens presenting cells in cervical epithelium, thus changes in their density or/and function may profoundly influence the proper activation of the afferent arm of immune response in cases of HPV-related intraepithelial lesions. AIM OF THE STUDY: Assessment of intraepithelial Langerhans cell count changes in CIN I/CIN II after human recombinant interferon gamma (IFNgamma) application and correlation with clinical outcome. MATERIAL & METHODS: The present study is a part of prospective trial on IFNgamma application in the treatment of CIN I/CINII associated with high-risk HPV infection. Seventeen subjects underwent uniform IFNgamma treatment (four intracervical injections in a two-day interval for a total dose of 6,000,000 IU). Langerhans cells were stained within cervical punch biopsy specimens with the use of polyclonal anti-S-100 antibody according to the three-step indirect peroxidase protocol, and their mean count calculated for the following groups: before IFNgamma treatment launching, immediately after completion of the treatment, and after two months of follow-up. RESULTS: The analysis revealed a rapid and significant increase in Lagerhans' cell count immediately after treatment completion (21.17/mm2 and 25.94/mm2, respectively, at p = 0.019) which further increased in the group of complete response (in 9 subjects; 32.22/mm2). After transient elevation of the Langerhans' cell count it returned to a level even lower than initially in the non-responder group (4 subjects; 20.25/mm2). CONCLUSION: Our data strongly support the observation from static studies suggesting that regression of HPV-related cervical lesions is associated with increased density of epithelial Langerhans cells.
