ABSTRACT
Objective To observe the effect of transfer factor on immunity in patients with varruca plana and the clinical effect of treatment. Methods Sixty patients with varruca plana were randomly divided into a treatment group (treated with transfer factor) and a control group (treated with routine therapy). Before and after the treatment, T-lymphocyte subgroups in peripheral blood of all the patients were determined by flow cytometry and serum levels of interleukin-10 (IL-10)and in-terferon-gamma (INF-γ)were detected by ELISA. The same detections were done to the twenty healthy volunteers as healthy controls. Results Effective rates in the treatment group and control group were 76.67 % and 43. 33 %, respectively (x2=5. 63,P<0.05). Decrease of CD3+ cells, CD4+ cells, CD4+/CD8+ ratio and increase of CD8+ cells were found in varruca plana group as com-pared with the healthy controls(P<0.01 ). After the treatment of transfer factor, increase of CD3+ cells ,CD4+ cells (P<0.05), CD4+/CD8+ ratio (P<0. 01)and decrease of CD8+ cells(P<0.01)were found in the treatment group as compared with those before treatment, while there were no significant difference in the control group before and after the treatment. Higher IL-10 and lower INF-γ in serum were found in varruca plana group as compared with the healthy controls (P<0.05). After the treat-ment of transfer factor, decrease of IL-10 and increase INF-γ in serum (P<0. 05)were found in the treatment group as compared with those before treatment, while there were no significant difference in control group before and after the treatment. Conclusion The results reveal that immunity is im-paired in patients with varruca plana. Transfer factor can enhance the immunity of the patients. Therefore, varruca plana patients treated with transfer factor receive better effects.
