5-Hydroxytryptophan (5-HTP) treatment of a single case of Lesch-Nyhan syndrome showing compulsive self-mutilation, athetoid movements, and characteristic clinical biochemical picture was studied on a double-blind basis. 5-HTP or placebo was administered for seven fortnightly treatment blocks. 5-HTP produced a significant reduction of athetoid movement and a sedative effect but did not improve the patient's mood or reduce self-mutilation.
对一例患有强迫性自残行为、手足徐动症以及典型临床生化表现的莱施-奈恩综合征患者,采用双盲法研究了5-羟色氨酸(5-HTP)的治疗效果。5-HTP或安慰剂每两周给药一次,共进行七个治疗周期。5-HTP显著减少了手足徐动症,并有镇静作用,但并未改善患者情绪或减少自残行为。
