Experimental research on the therapeutic effect of MMR vaccine to juvenile-onset recurrent respiratory papillomatosis

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.
