Fifteen patients with chronic urticaria were treated with ultraviolet light B (UVB) for 1-3 months during the spring 1984 and a follow-up study was performed in November 1984-January 1985. Patients with cold urticaria, cholinergic urticaria and dermographism became clearly better or got rid of their symptoms more often than those with "non-specific" chronic urticaria. The good results achieved during the phototherapy held during the summer but in the autumn urticaria became worse in one third of the cases. The result suggests that UV-therapy might be worth trying in many patients with chronic urticaria.
