Homovanillic acid (HVA) and 5-hydroxy indole acetic acid (5-HIAA) concentrations have been estimated in the cerebrospinal fluid (CSF) of 16 and 18 patients respectively with Parkinsonism both before and during treatment with l-dopa. The rise of HVA correlated with dose of l-dopa. An increase of HVA concentration to less than 0·10 μg/ml. was associated with little or no clinical improvement. The five patients with the greatest increase of HVA concentration/g l-dopa showed little or no improvement from treatment and four of these patients had normal pre-treatment HVA and 5-HIAA. In those patients who responded well to l-dopa the CSF HVA/g l-dopa was intermediate between that of these two groups. It is suggested that change in HVA content of CSF during l-dopa treatment might be of value in the prediction of response to l-dopa.
分别测定了16例和18例帕金森病患者在左旋多巴治疗前及治疗期间脑脊液（CSF）中高香草酸（HVA）和5-羟吲哚乙酸（5-HIAA）的浓度。HVA的升高与左旋多巴的剂量相关。HVA浓度升高至低于0.10μg/ml时，临床改善很少或没有改善。HVA浓度/每克左旋多巴升高幅度最大的5例患者治疗后改善很少或没有改善，其中4例患者治疗前HVA和5-HIAA正常。在对左旋多巴反应良好的患者中，脑脊液HVA/每克左旋多巴处于这两组之间。提示左旋多巴治疗期间脑脊液中HVA含量的变化可能对预测左旋多巴的反应有价值。
