An open labeled, comparative clinical study on efficacy and tolerability of oral minipulse of steroid (OMP) alone, OMP with PUVA and broad/narrow band UVB phototherapy in progressive vitiligo

Background: Several modalities of treatment have been tried in vitiligo with varied results; however, Indian data on comparative studies of two or more therapies are limited. Aims: We compared different phototherapy methods with an oral steroid as an adjunct to determine the method with the best tolerability and efficacy. Methods: Eighty-six patients with progressive vitiligo were randomly assigned to different study groups according to a continuous selection method over a period of one year. Group 1 was given OMP PUVA, group 2 OMP UVB (NB), group 3 OMP UVB (BB) and group 4 was given OMP alone. Each patient was followed up for six months and then released from treatment. Clinical evaluation was made at the end of three and six months. Results: In group 1 (OMP PUVA), marked improvement was seen in 18.51 while moderate improvement was seen in 66.66 of the patients. Marked improvement was seen in 37.03 in group 2 (OMP NB-UVB) while 44.44 had moderate improvement. In group 3 (OMP BB UVB), 8.33 showed marked improvement while moderate improvement was seen in 25 of the patients. Marked and moderate improvement was seen in 5 and 10 of group 4 (OMP) patients, respectively. Conclusions: Our study compared four treatment modalities in vitiligo patients, out of which oral minipulse of steroids (OMP) only had an adjunct value and was not very effective by itself. Narrow band UVB has a definite edge over broad band UVB and should be preferred when both options are available. NB-UVB and PUVA showed comparable efficacy.
