Catecholamine의 주요 대사산물인 혈장 HVA 및 MHPG 농도변동과 약물에 대한 반응, 임상변인들과의 연관성에 대한 많은 연구들이 진행되고 있다. 본 연구에서는 이를 추시 확인하고 혈장 HVA 및 MHPG 농도의 생물학적 지표로서의 가능성에 대하여 확인하고자 하였다. 16명의 정신분열병 환자를 대상으로 정형적 항정신병약물인 haloperidol복용을 2주간 중단하여 약물의 영향이 최소화된 상태에서 혈장 HVA 및 MHPG 농도를 측정하였다. 항정신병약물 투여 24시간 후의 발병연령과 HVA 및 MHPG 농도의 변동을 알아보았다. 혈장 HVA 및 MHPG의 측정은 고압액체크로마토그래피-전기화학측정방법을 이용하였다. 항정신병약물을 투여하여 DA계의 변화를 유도한 후 혈장 HVA와 MHPG 농도의 변화를 살펴본 결과에서 각 개인별로 혈장 HVA와 MHPG 농도가 감소하는 결과를 볼 수 있었다. 혈장 HVA와 MHPG 농도와 발병연령과의 상관관계를 볼 때 26.56세 이하에서 발병한 환자 군에서 26.56세 이상에서 발생한 군보다 더 낮은 혈장 HVA와 MHPG 농도를 보이고 있다. 이러한 농도의 차이는 항정신병약물을 투여 후 더욱 뚜렷해지는 것을 볼 수 있었다. 이 결과는 혈장 HVA와 MHPG 농도가 정신분열병의 생물학적 지표로서의 의미를 보여준다고 생각된다. 또한 정신분열병을 생물학적인 지표에 의해서 좀 더 동질적인 아집단으로 구분할 수 있을 가능성과 정신분열병이 단일 질병이 아니라 여러 아집단으로 구성된 증후군일 가능성도 제시하고 있다.
Abstract
Objectives : The author investigated the possibility of homovanillic acid (HVA) and methoxyhydroxyphenylglycol(MHPG) concentrations in plasma as biological markers before and after single haloperidol treatment. Methods : Sixteen patients with schizophrenia were enrolled after two-weeks washout of neuroleptics. Baseline plasma was obtained at 8:00 AM after washout. After baseline sampling, the patient was treated with haloperidol and consequent sampling was done 24 hours later. The concentrations of HVA and MHPG were compared with age of onset. The HVA and MHPG levels were assayed using high pressure liquid chromatography-electrochemical detection method. Results : A significant association was observed between the age of onset and plasma HVA concentration after haloperidol treatment. The early onset group had lower plasma HVA concentration than the late onset group. More significant association was observed between the age of onset and plasma MHPG concentration after haloperidol treatment. The early onset group had much lower plasma MHPG concentration than the late onset group. Conclusions : These findings suggest that the activities of dopamine and norepinephrine are different with respect to age of onset after haloperidol treatment. Plasma HVA and MHPG concentration can be used as biological markers for subgrouping of schizophrenia. These results might suggest that schizophrenia is not a single disease, but a syndrome.
