Abstract

OBJECTIVE : To evaluate the efficacy of MMR vaccine in the treatment of juvenile-onset recurrent respiratory papillomatosis as adjuvant therapy by experimental research.
METHODS : Thirty-one children with RRP were enrolled and assigned randomly to intervention group or control group. Fifteen subjects in intervention group were treated with local application MMR vaccine on the lesion after surgery; sixteen subjects in the control group were treated with surgical excision alone. The quantity of virus of positive specimens was measured by fluorescence quantitative polymerase chain reaction.
RESULTS : After treatment with MMR vaccine, viral load of intervention group was (9.56 ± 11.03) × 108  copies/ml, that of control group was (22.01 ± 17.78) × 108 copies/ml, and there was significant difference between the two groups (P = 0.040).
CONCLUSIONS : Local application MMR vaccine as adjuvant therapy can reduce HPV viral load significantly. It is suggested that the MMR vaccine may inhibit replication of HPV DNA, but the curative effect needs further confirmation.
