Background: Prurigo nodularis (PN) is a chronic disease of which treatment choices are limited. Among them, thalidomide and phototherapy have been used with satisfactory results. Unfortunately, the possibility of side effects limits their use.
Objective: To evaluate the efficacy of a sequential combined treatment with thalidomide and ultraviolet B (UVB) therapy in order to minimize side effects and, thus, making possible a long-term treatment.
Methods: A prospective open trial combining thalidomide as initial therapy followed by narrow-band UVB (TL01) irradiation until complete or almost complete remission of the disease was achieved.
Results: An excellent response was obtained after an average of 12 weeks of thalidomide therapy and 32 UVB courses.
Conclusions: Sequential combined therapy with thalidomide and narrow-band UVB therapy could improve the management of prurigo nodularis with minimal side effects, although it should probably be reserved to men and women over 50 years of age.
