Autoimplantation technique in the treatment of anogenital warts: a clinico-immunological study.

An autoimplantation technique was adopted in the treatment of 50 cases of anogenital warts and was compared with the conventionally used podophyllin regimen in a matched group of 50 patients. They were assessed with 15 untreated subjects in a control group for the rate of clinical cure after 6 weeks, recurrence after 1 year follow up and for humoral and cell mediated immune responses before and after treatment. In the podophyllin group, 70% of patients were cured after 6 weeks while in autoimplantation, only 44% of patients were cured, and none in the control group had natural remission of warts without any treatment. After 1 year all the cured cases (100%) that completed follow up had recurrence of warts with podophyllin treatment, while none had recurrence of lesions in the autoimplantation group. Results of the humoral and cell mediated immune (CMI) response studies revealed that autoimplantation technique significantly augmented both humoral and CMI responses while there was not significant change in the immune status after podophyllin treatment (P > 0.001).
