ABSTRACT

BACKGROUND:

The pathogenesis of alopecia areata is still unknown, however autoimmune mechanism is strongly suggested. The topical immunotherapy using potent sensitizer has been used as new therapeutic modality. By this method in one half and to one third of the patients, hair growth is observed.

OBJECTIVE:

To evaluate the immunological profile between responders and non-responders to dphencyprone (DPCP) topical immunotherapy in alopecia areata patients.

METHODS:

Aker sensitization, DPCP was applied to the patients' scalp weekly for three months. Before and after treatment the therapeutic effect was evaluated by clinical observation by following items complete baldness, baldness+vellus, baldness+terminal hair and normal hair. Peripheral T cell and T cell subsets, B cell and delayed hypersensitivity with various antigens were evaluated before and after treatment.

RESULTS:

The immunologic difference between responders and non-responders was not statistically different.

CONCLUSION:

It is suggested that no major immunologic difference was observed between responders and non-responders before and after DPCP topical immunotherapy. Local mechanism seems to be related in the response to immunotherapy.
