“…However, there is still some controversy about the optimal UVA1 single and cumulative dose. So far, the doses applied have ranged from low, with 10–30 J/cm 2 [2], through medium, at 50–60 J/cm 2 [3, 4], to a high-dose regimen [1, 4, 5], with 130 J/cm 2 . For that reason, we compared in a randomized, controlled, prospective pilot study the efficacy of ‘high-dose’ (maximum single dose of 130 J/cm 2 , maximum cumulative dose of 1,840 J/cm 2 ), ‘medium-dose’ (maximum single dose of 65 J/cm 2 , maximum cumulative dose of 975 J/cm 2 ) and ‘low-dose’ (maximum single dose of 20 J/cm 2 , maximum cumulative dose of 300 J/cm 2 ) UVA1 therapy in patients with acutely exacerbated AD (SCORAD >30) [6].…”
