Abstract

BACKGROUND: Ultraviolet A1(UVA1) phototherapy is increasingly being used in the treatment of morphea, atopic dermatitis, lupus and some other recalcitrant dermatoses. We present a retrospective review of our experience with this modality.

AIM: To evaluate the treatment response rates for various dermatoses and adverse effects of UVA1 phototherapy.

METHODS: We reviewed phototherapy notes along with electronic and/or paper case records for all patients treated with UVA1 phototherapy from October 1996 to December 2008.

RESULTS: A total of 269 patients (outcomes available for 247) had 361 treatment courses (treatment data available for 317 courses) over this period. We found phototherapy to be beneficial in 28 (53%) of 53 patients with atopic dermatitis and 19 (51%) of 37 patients with morphea. A beneficial outcome was recorded in all six (100%) cases of urticaria and six (85.7%) of seven patients treated for a polymorphic light eruption. Benefit was also recorded in systemic lupus erythematosus (8 (44.4%) of 18), lichen sclerosus (6 (42.9%) of 14), mastocytosis (2 (33.3%) of 6), necrobiosis lipoidica (4 (30.8%) of 13), granuloma annulare (2 (25%) of 8), scleroderma (2 (22.2%) of 9) and keloids (1 (7.7%) of 13). Overall, treatment was well tolerated with no patients having to stop treatment due to adverse effects.

LIMITATIONS: This is a retrospective study with no control group. Subjective/recall bias is quite possible as a number of patients were followed up over the phone.

CONCLUSIONS: Our data suggest that ultraviolet A1 can be considered for the treatment of selected dermatoses. However, long-term malignancy risk is as yet unknown.
