Abstract
배경: 근위축성측삭경화증(Amyotrophic Lateral Sclerosis; ALS)은 뇌와 척수의 상위 및 하위 운동신경원 세포의 점진적인 소멸을 특징으로 하는 비가역적 신경퇴행성질환이다. 현재까지 많은 연구가 있었으나, Riluzole만이 효과가 입증되어 있는 실정이나 이 또한 생존기간을 3-4개월 정도 늘리는 효과가 있을 뿐이다. 기존 문헌에 의하면, Erythropoietin (EPO)가 다양한 작용기전에 의하여 신경보호효과가 입증되고 있으며, 이에 ALS환자를 대상으로한 EPO의 효과를 확인해보고자 하였다. 대상과 방법: 총 55명이 본 연구의 대상군으로 설정되었다. 3개월 간의 도입부 기간을 두어 환자의 증상 진행경과를 관찰하였다. EPO 투여군에게 1개월 간격으로35,000 IU의 recombinant human EPO가 정맥내로 투여되었으며, 1차 투여 시점 후 3개월 시점을 유효성 판정을 위한 마지막 방문으로 설정하였다. ALS functional rating scale-revised(ALSFRS-R)의 변화량이 일차유효성 판정에 이용되었으며, 심근경색, 악성 고혈압, 혈소판 증가 등의 주요 이상반응과 혈액학적 변화 유무가 안전성 평가에 사용되었다. 결과: 대조군과 비교하여, EPO 투여군에서는 ALSFRS-R의 변화량이 도입부 3개월 간보다 EPO 투여 후 3개월 간에 적은 것이 확인되었다. 또한, 비교적 유병기간이 짧고 빠른 질병의 경과를 보이는 환자들에서 EPO의 효과가 있는 것으로 나타났다. EPO 투여 후 환자가 호소하거나 의사에 의해확인된 즉시 효과들로는 근력의 향상, 침흘림 감소, 강직성 감소, 심리 상태 안정 등이 확인되었으며, 주된 이상반응이나 혈액학적 변화는 관찰되지 않았다. 결론: ALS환자에게 rhEPO의 정맥내투여의 안전성이 확인되었으며, EPO의 신경보호효과와 치료 잠재력을 고려해 볼 때 추가 조사의 가치가 충분하다고 판단된다.; Background Amyotrophic lateral sclerosis (ALS) is a rapidly progressive, fatal neurodegenerative condition characterized by loss of upper and lower motor neurons in the brain and spinal cord. In spite of numerous researches, riluzole remains the only effective therapy, but with only minimal effects on survival. In previous reports, erythropoietin (EPO) has shown the neuroprotective effects, including anti-apoptotic and anti-inflammatory actions on central nervous system (CNS) in vivo as well as in vitro. Therefore, we evaluated the effects of erythropoietin therapy in patients with ALS. Methods Fifty-five patients with probable and definite ALS on the basis of El Escoreial criteria were recruited for this study. After the lead-in period for 3 months to assess the progression of disease, recombinant human erythropoietin (rhEPO)was injected intravenously twice at an interval of 1 month (35,000 IU/30min/50ml) to the patients (rhEPO group) who agreed to informed consent. Patients were monitored by clinical evaluation including ALS functional rating scale-Revised (ALSFRS-R), subjective symptoms and signs after rhEPO therapy. Change in ALSFRS-R score during 3 months after treatment was compared with those during lead-in period in both rhEPO and control groups. To assess the safety, patients were closely monitored for adverse events including thrombocytosis, malignant hypertension, and myocardial ischemia. Besides hemodynamic monitoring, each patient had complete blood cell count, blood urea nitrogen, creatinemia, electrolytes, glucose and liver enzyme. Findings Compared with control group, the rhEPO treatment slowed down the changes of ALSFRS-R during 3 months after EPO injection in rhEPO group (p=0.034). In addition, the relatively good response to rhEPO was shown in patients with short duration and rapid progression among the rhEPO group. The intravenous administration of rhEPO also had modest but significant beneficial effects including improvement of muscle power, decreased drooling, mood stabilization, and decreased spasticity. No significant adverse effects were noted. The hematocrit, hemoglobin, red blood cell counts, liver enzyme, and blood pressure remained stable throughout the 2 months follow-up period. Interpretation Intravenous rhEPO in ALS is both safe and well tolerated. Moreover, we might suggest that rhEPO has the neuroprotective effect and therapeutic potency, and this approach may be worthy of further investigation.
