title: Vitiligo.
abstract: BACKGROUND
  Vitiligo is an acquired skin disorder characterised by white (depigmented) patches in the skin, due to the loss of functioning melanocytes. The extent and distribution of vitiligo often changes during the course of a person's lifetime and its progression is unpredictable.
  
  
  METHODS
  We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of medical treatments, and of ultraviolet light treatments, for vitiligo in children and in adults? We searched: Medline, Embase, The Cochrane Library and other important databases up to March 2007 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
  
  
  RESULTS
  We found 25 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
  
  
  CONCLUSIONS
  In this systematic review we present information relating to the effectiveness and safety of the following interventions: corticosteroids, oral levamisole, topical immunomodulators, topical Vitamin D analogues, ultraviolet A plus psoralen (PUVA), and ultraviolet B (narrowband, and broadband).
