- Abstract
<bold>Background: </bold>Very few studies have been performed to evaluate the efficacy and safety of narrow-band ultraviolet B (NBUVB) therapy in Indian patients with vitiligo and are of small sample size.<bold>Aims: </bold>The purpose of this study is to know the efficacy and safety of NBUVB in 150 vitiligo patients of various age groups.<bold>Methods: </bold>One hundred fifty patients (69 males, 81 females), aged 3-70 years, with vitiligo were treated twice weekly with NBUVB. The starting dose was 250 mJ/cm2 in adults and 150 mJ/cm2 in children, with 20% dose increments at each subsequent visit given for a maximum period of 1 year and were followed-up for 6 months for stability of repigmentation. Statistical methods were employed to establish the relation between the response and the number of exposures, duration of treatment, cumulative dose and the compliance.<bold>Results: </bold>Analysis of our study showed that a majority of our cases, about 73, achieved 25-75% repigmentation, with an average of 51+/-19 exposures, 51 had <25% repigmentation, with an average of 19+/-11 exposures and 26 had >75% repigmentation, with an average of 74+/-24 exposures. Good response to therapy was directly associated with good compliance, more number of exposures and increasing cumulative dose, which was statistically significant (P<0.01). Adverse effects were minimal. Only three patients developed depigmentation of repigmented sites during follow-up.<bold>Conclusion: </bold>Our study proves that NBUVB therapy is an effective and safe tool in the management of vitiligo, with good stability of repigmentation and cosmetic appearance.
