ABSTRACT
Background: Cutaneous warts are small skin lesions formed as a result of infection by the human papilloma virus (HPV). In the lesion, viral manipulation creates a microenvironment that favors virus survival and reproduction. Most lesions eventually regress, probably as a result of a Th1-mediated immune response. However, some warts fail to regress and become persistent. Objective: The efficacy of treatment of persistent HPV-caused warts with Energetics of Living Systems acupuncture and monitored immune system involvement was tested. Methods: Eighteen patients with persistent warts were recruited for the study; 9 received acupuncture treatment and 9 received placebo. Each patient was treated 4 times. Results: Clinical success was defined as total clearance of all lesions with no recurrence for 3 months. In the treatment group, clinical success was 36.6% versus 0% in the placebo group. In the treatment group, the level of interleukin (IL)-10 decreased. In a comparison of patients with cleared warts and overall patients with nonresponding warts, different expression levels of IL-8, IL-10, tumor necrosis factor-α, IL-6, and interferon-γ were found, although these differences were not always statistically significant. Trends of differences (not significant) were observed in leukocyte levels. Acupuncture eliminated persistent warts in some of the patients, along with inducing changes in immunologic parameters. Conclusions: Taking the clinical and immunologic outcomes together, clearance of persistent warts following acupuncture might be due to a shift toward a Th1 immune response, or an anti-inflammatory effect against the lesion-induced microenvironment.
