OBJECTIVE: To determine the effects of polysaccharide nucleic acid fraction of bacillus calmette guerin (BCG-PSN) on serum levels of interleukin-4 (IL-4) and interleukin-12 (IL-12) in patients with condyloma acuminatum (CA) and to investigate the mechamism of immunoregulation of BCG-PSN on CA. METHODS: Sixty CA cases were randomly divided into 2 groups. The serum levels of IL-4 and IL-12 were respectively measured by Double-antibody sandwich ELISA method before and after the treatment. The serum levels of IL-12 and IL-4 of health control were also measured. The recurrent rate of each group was used as an index to assess the effect of BCG-PSN in CA patients. RESULTS: Compared with healthy controls, the serum levels of IL-12 in patients with CA were decreased significantly (P < 0.05), while the serum levels of IL-4 were increased significantly (P < 0.05) before the treatment. The serum levels of IL-12 were negatively correlated with the serum levels of IL-4 (r = -0.287, P < 0.05). After the treatment, the serum levels of IL-12 were increased significantly( P < 0.05), and the serum levels of IL4 were decreased significantly (P < 0.05) in the treatment group. But in the control group, the serum levels of IL-12 and IL-4 were similar before and after the treatment (P > 0.05). The recurrent rate of treatment group was significantly lower than that of the control group (chi2 = 4.356, P < 0.05). CONCLUSIONS: There is an imbalance of Th1/Th2 cytokines production in patients with condyloma acuminatum. BCG-PSN could increase the serum level of IL-12 and decrease the serum level of IL-4 in CA patients. BCG-PSN could decrease the recurrent rate of CA. The effect may be related to the regulation and modulation of BCG-PSN to Thl/Th2 cytokines imbalance,which then enhances the cellular immunity in CA patients.
