Abstract
Background
: Alendronate is on of the anti-resorptive drugs for the treatment of osteoporosis and results in a decrease of bone turnover. HRT is also known to decrease the bone turnover. Combination therapy with HRT and alendronate has made significant increase of BMD in postmenopausal women. But there were no available long-term results about combination therapy of HRT and alendronate on Korean osteoporotic women.

Methods : Eighty postmenopausal women with osteoporosis who visited the Climacteric Clinic in Samsung Cheil Hospital & Women's Health Care Center from April to July 1999 were subjects. Randomized open labeled case control study was made. We evaluated 37 postmenopausal osteoporotic Korean women who were treated for 2 years after enrollment. Subjects in Group I were treated with HRT only and group II had HRT with alendronate 10 mg daily. Subjects also were measured BMD at lumbar spine and makers of bone turnover before, one and two year after treatment.

Results : Common reasons for dropouts were side effects of HRT such as breast tenderness, irregular vaginal bleeding, economic problems, long distance from clinic etc. BMD in lumbar spine was increased 10.1% in the first year, and 12.0% in the second year in subjects treated with HRT and alendronate. But in HRT only group BMD increased to 6.4% in the first year and 7.8% at second year. Markers of bone turnover were decreased significantly in both groups compared with baseline value, but the percent changes of markers after 1 year and 2 years between the two groups were not significant.

Conclusion : This study demonstrated that, in postmenopausal Korean women with osteoporosis, 2 years of combination therapy with HRT and alendronate resulted in a significant and sustained increase in spinal BMD than HRT and alendronate resulted in a significant and sustained increase in spinal BMD than HRT only group.
초록
연구배경 : 알렌드로네이트는 골다공증 치료에 이용되는 골흡수 억제제로서 골대사를 억제한다. 여성호르몬 보충요법은 역시 골대사를 감소시킨다고 알려져 있다. 이 두 약제의 병합사용은 폐경 여성에서 유의한 골밀도의 증가를 나타낸다. 그러나 아직 한국여성에서 두 약제의 장기간 사용에 대한 자료가 부족한 실정이다.

방법 : 1999년 4월부터 7월까지 삼성제일병원 갱년기클리닉을 방문한 여성 중 요추 골밀도가 2.5 표준편차 이상 감소한 골다공증 여성 80명 중 2년 동안 치료를 완료한 37명을 대상으로 하였다. 대상자는 무작위로 두 군으로 구분하였으며, 한 군은 여성호르몬과 알렌드로네이트를 병합사용하였으며, 다른 군은 여성호르몬만 단독으로 사용하였다.

결과 : 치료 탈락자들의 흔한 이유로는 유방통이나 불규칙적인 자궁 출혈, 경제적인 문제 및 거리상의 문제 등으로 나타났다. 치료전의 골밀도와 비교한 결과 여성호르몬과 알렌드로네이트를 병합사용한 군에서는 1년 후 10.1%의 골밀도 증가를 나타냈으며, 2년 후 12.0%의 증가를 보였다. 그러나 여성호르몬을 단독으로 사용한 군에서는 6.4%, 7.8%의 골밀도 증가를 나타냈다. 골대사 지표의 치료 후 1년, 2년 후 모두 치료 전에 비해 유의한 감소를 보였으며, 두 군사이에서는 유의한 차이를 나타내지 않았다.

결론 : 골다공증이 있는 한국 여성에서 2년간 여성호르몬과 알렌드로네이트를 동시에 사용한 결과 여성호르몬 단독 사용군에 비해 지속적으로 유의한 골밀도의 증가를 나타냈다.
