RESUMO
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 efficacy, 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 efficacy 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 efficacy 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.

BACKGROUND: Very few studies using the combination of topical 8-methoxypsoralen (8-MOP) and narrow-band ultraviolet B (NBUVB) have been performed, especially in Indian patients. A combination of oral psoralen with NBUVB has been shown to have a superior efficacy as compared with NBUVB alone in psoriasis. AIMS: Comparison of the efficacy of topical psoralen NBUVB (combination) versus NBUVB alone in psoriasis. METHODS: Thirty patients with plaque psoriasis were taken up for the study and NBUVB phototherapy was given twice weekly. The target lesions on one side were treated with 0.1% topical 8-MOP 15 min before the irradiation. The treatment period was 12 weeks or 24 exposures. RESULTS: The number of treatment sessions and cumulative NBUVB doses were lower in the combination therapy as compared with NBUVB monotherapy, although the differences were not statistically significant. CONCLUSION: To conclude, topical 8-MOP enhances the therapeutic effects of NBUVB therapy without increasing the incidence of adverse effects.

Ever since artificial TL-01 lamps were developed, narrowband ultraviolet B (NBUVB) has gained giant strides in dermatology. Psoriasis is one of the common indications for the use of NBUVB in present day dermatology. We discuss here the evolution of NBUVB, its mechanism of action pertaining to psoriasis, indications and contraindications, dosimetry, complications of NBUVB while being used in patients with psoriasis, its merits and demerits in comparison with broadband UVB and psoralen+UVA (PUVA), and recent developments in the delivery system of NBUVB.
