“…A recent open-label, dose-escalating study in 12 adult patients with severe AD demonstrated a 52% improvement in the clinical score over baseline values at week 24, and only 1 patient withdrew from further treatment because of adverse events, a result that is clinically meaningful. 96 By using the same scoring system (six-area, six-sign SD score), azathioprine showed a 37% improvement over baseline values at week 12 (placebo 20%) in a double-blind, placebo-controlled study in patients with moderateto-severe AD older than 16 years, 97 thus confirming efficacy as assessed during an earlier trial. 98 Although adverse events, such as leucopenia and increased liver transaminase levels, need to be carefully monitored, these data indicate that azathioprine is effective in AD.…”
