Study Summary

The purpose of this study is 1) to determine whether Imiquimod or Steroid pretreatment modifies UVB laser light response resulting in increased cell death compared to UVB laser light alone; 2) to determine if pretreatment of psoriatic lesions with Imiquimod or Steroid prior to UVB laser light exposure selectively effects various T cell functions; 3) to determine clinical results from the Imiquimod/Steroid/UVB laser light and correlate those changes with immuno-histochemical changes in the skin; and 4) to determine if single high dose lesion limited UVB laser light intervention combined with Imiquimod or Steroid influences T cell changes

Primary Outcome

Lesions were treated with either Imiquimod or Clobetasol cream. Lesions were subsequently treated with UVB and biopsied. From the biopsy samples obtained from the Imiquimod arm, quantitative PCR was performed to measure levels of Myx A, an imiquimod response gene.

Interventions

  • DRUG Imiquimod
  • DRUG Clobetasol
