Low-Dose UVA1 Radiation in Cutaneous Lupus Patients
This is an open-label trial to assess the efficacy, safety, and immunologic effects of uVa1 phototherapy on patients with cutaneous lupus erythematosus. Fifteen patients will be recruited to receive low dose (20 J/cm2) uVa1 phototherapy treatment three times per week for 10 weeks followed by an eight-week observation phase. in the event that a patient experiences adverse events (e.g. erythema) with the 20 J/cm2 dose, the dose will be decreased to 6 J/cm2. if symptoms persist, the patient will be withdrawn from the study. Patients will be allowed to continue on their current medications throughout the study. Patients will be assessed prior to, during, and at the end of uVa1 treatment at the end of the observation period. any adverse events and symptoms of SLe flares will be assessed simultaneously. Serological studies will be completed prior to treatment, during the treatment phase, and at the end of the observation phase. optional biopsies will be performed at the beginning and end of the active treatment phase. Gene and protein expression studies will be conducted on blood and skin samples with the intent of understanding the mechanism of action for uVa1 treatment in cutaneous lupus.
