ABSTRACT
Background: Narrow band ultraviolet-B (NB-UVB) is now one of the most widely used modalities in the treatment of psoriasis. However, despite its high effi cacy, conventional Goeckerman treatment has fallen out of favor in recent years and some institutions are now using NBUVB with coal tar as their regimen. Objective: To evaluate the effi cacy of NB-UVB, Goeckerman therapy and the effect of addition of retinoid to the treatment regimen in the treatment of psoriasis. Patients and Methods: A retrospective analysis of 65 patients who underwent 81 courses of treatment in our department was undertaken. The effi cacy of NB-UVB and Goeckerman therapy individually, and in combination with acitretin was assessed. Data were analysed to evaluate the contribution of acitretin to these modalities. Results: PASI-75 responses in the NB-UVB, retinoid + NB-UVB (re-NB), Goeckerman and retinoid + Goeckerman (re-Goeckerman) groups were achieved for 12 of 31 patients (39%), 13 of 21 patients (62%), 15 of 17 patients (88%) and 10 of 12 patients, respectively. The addition of acitretin to both modalities reduced both the number of sessions and the cumulative ultraviolet-B dose delivered. Limitations: This is a retrospective study, the patients were not randomized and the number of patients in the treatment groups were dissimilar. Conclusion: Goeckerman therapy is more effective than NB-UVB phototherapy. Although the addition of acitretin to both NB-UVB and Goeckerman therapy did not contribute to treatment outcomes in terms of PASI-75 responses, it enabled a reduction in UV exposures and enhanced efficacy.
