| Summary: | Background
Vitiligo may be treated with hospital‐based phototherapy, but this requires long‐term frequent appointments. Self‐treatment using home‐based phototherapy is a convenient alternative, which may improve adherence and results, but evidence is limited, and so it is not routinely recommended. This systematic review aims to assess the effectiveness and safety of home‐based phototherapy for vitiligo.
Methodology
Searches were conducted on Medline, Scopus and The Cochrane Library for randomised controlled trials comparing home‐based phototherapy with institution‐based phototherapy or placebo/no phototherapy for vitiligo. The primary outcome was treatment effectiveness. CASP criteria were used for quality assessment. Data were synthesised in a meta‐analysis where appropriate.
Results
Three studies (195 participants) were included: two compared home‐based with institution‐based phototherapy, and one compared home‐based phototherapy with placebo. Studies were of mixed quality. Therapy regimes varied across studies. Findings on effectiveness were contradictory across studies with variable rates of repigmentation. There was no significant difference in repigmentation rates between the groups, although adherence to treatment schedules was significantly better in home‐based groups. Adverse effects were significantly higher in home‐based groups. No long‐term data were reported on maintenance of treatment benefits.
Conclusions
Although adherence to treatment was significantly better with home‐based phototherapy, data were insufficient to form conclusions on effectiveness. Home‐based phototherapy had a significantly higher risk of adverse effects, making it difficult to recommend in clinical practice. However, as it offers logistical advantages for patients, its effectiveness alongside additional safety measures should be explored further in large‐scale, good‐quality RCTs, with standardised outcome measures, including patient‐reported outcomes. |
