Schematic overview of normal donors, asymptomatic carriers and HAM/TSP patients.

EDSS = expanded disability status scale, “0” reflecting normal neurological examination and “10” death; PVL = proviral load expressed as HTLV-1 copies per 104 PBMCs; ND = not determined; predn = prednisone; AA = high-dose ascorbic acid; 3TC = lamivudine; baclo = baclofen; AZT = zidovudine; F = female; M = male.EDSS即扩展残疾状态量表（expanded disability status scale），其评分“0”代表神经系统检查正常，“10”代表死亡；PVL即前病毒负荷（proviral load），以每10⁴个外周血单个核细胞（peripheral blood mononuclear cells, PBMCs）中的HTLV-1拷贝数表示；ND即未检测（not determined）；predn即泼尼松（prednisone）；AA即大剂量抗坏血酸（high-dose ascorbic acid）；3TC即拉米夫定（lamivudine）；baclo即巴氯芬（baclofen）；AZT即齐多夫定（zidovudine）；F即女性（female）；M即男性（male）。
