Abstract

Background: Δ9-Tetrahydrocannabinol (Δ9-THC) is the active compound of Cannabis sativa with appetitestimulating properties. This study evaluated the effect of low doses of oral Δ9-THC on self-reported symptoms of patients suffering from chronic anorexia nervosa (AN).

Methods: Nine female subjects over 18 years of age participated in the study. Six were diagnosed according to DSM-IV criteria with AN restrictive type and three with active AN binge-purge type. Their mean age was 45.0±3.2 years and their BMI was 16.1±1.6 kg/M2. They completed questionnaires before and after treatment with Δ9-THC (1 mg/day for one week and 2 mg/day for three weeks). The primary outcome was improvement in the way patients perceived their eating behavior.

Results: Significant improvements were found in selfreported body care, sense of ineffectiveness, asceticism and depression. There were no significant changes in BMI.

Conclusions: Δ9-THC may be an effective component in treating the psychological symptoms of AN.

Δ9-THC对神经性厌食症心理症状的影响:一项初步研究
背景:Δ9-Tetrahydrocannabinol (Δ9-THC)是大麻中具有刺激食欲的活性化合物。本研究评估了低剂量口服Δ9-THC对慢性神经性厌食症(AN)患者自我报告症状的影响。方法:9名年龄在18岁以上的女性受试者参与研究。6例根据DSM-IV诊断为AN限制性型,3例为活动性AN狂泻型。平均年龄45.0±3.2岁,BMI为16.1±1.6 kg/M2。他们在Δ9-THC治疗前后分别完成问卷调查(1 mg/天,1周,2 mg/天,3周)。主要结果是患者对自己饮食行为的认知有所改善。结果:自我报告的身体护理、无效感、苦行和抑郁均有显著改善。BMI没有明显变化。结论:Δ9-THC可能是治疗an心理症状的有效成分。
