The clinical course of childhood and adolescent adrenoleukodystrophy before and after Lorenzoʹs oil

The clinical course of Japanese patients with childhood and adolescent adrenoleukodystrophy (ALD) who were treated with Lorenzoʹs oil after the progression of early symptoms was investigated by Kaplan–Meier analyses. Many of the early symptoms, including visual, personality, hearing, mental and speech disturbances, had already appeared when the oil therapy was started. These early symptoms appeared significantly faster than bed-ridden state or dysphagia (P<0.01). Gait disturbance appeared faster than bed-ridden state and dysphagia (P<0.05), and tended to appear later than the early symptoms. These results would reflect the early natural course of childhood and adolescent ALD before treatment, and provide a basis for the evaluation of therapeutic trials for ALD.
