Abstract
[한글]최근 지방조직에서 분비되는 adipo(cyto)kine은 비만, 당뇨, 관상동맥질환과 같은 대사성 및 혈관 질환의 병인에 중요한 역할을 하는 인자로 활발히 연구되고 있다. 그 중 adiponectin은 항염증 및 항동맥경화, 인슐린 감수성을 증가시키는 작용을 하며, resistin은 인슐린 저항성을 증가 시킴으로써, high-sensitivity C-reactive protein (hs-CRP), interleukin (IL)-6, tumor necrosis factor (TNF)-α등의 inflammatory marker와 밀접한 관계가 있다.폐경 후 여성은 지방 조직의 재분포가 일어나며, 인슐린 저항성, 고혈압, 고지혈증과 같은 대사성 증후군과 심혈관 질환의 위험도가 증가한다. 이러한 폐경 여성의 변화에 adipokine이 중요한 역할을 할 것으로 생각된다. 따라서, 본 연구는 폐경 후 adipokine의 변화와 이에 여성 호르몬 대체 치료가 미치는 영향을 알아보고, adipokine 변화와 inflammatory marker의 상호관계를 알아보고자 하였다.36명의 폐경 전 여성과 33명의 건강한 폐경 여성을 대상으로 하였으며, 폐경 여성 중 27명은 6개월간 호르몬 치료를 시행 하였다. 각각 체질량지수, 허리엉덩이 둘레비 및 혈압을 측정하였으며, 지질대사인자 (lipid profile), 공복혈당, 인슐린, hs-CRP, IL-6, TNF-α, adiponectin, resistin을 측정하였으며, 인슐린 저항성은 homeostasis model assessment of insulin resistance (HOMA-IR) index로 계산하여 평가하였다.폐경 전 여성과 비교할 때 폐경 여성에서 총콜레스테롤, HDL-콜레스테롤, 공복혈당 (각각 169.39±30.04 vs. 197.55±35.37 mg/dL, 53.94±10.54 vs. 59.99±11.55 mg/dL, 4.75±0.36 vs. 5.04 ± 0.46 mmol/L, P < 0.05)이 유의하게 높았으나, HOMA-IR index는 유의한 차이를 보이지 않았다. Adiponectin은 폐경 여성에서 유의하게 증가되어있는 반면 (4.56±2.42 vs. 7.76±4.99 µg/mL, P < 0.05), resistin, hs-CRP, TNF-α, IL-6는 유의한 차이를 보이지 않았다. 다변량 회귀 분석하였을 때, hs-CRP는 체질량지수와 양의 상관관계를 나타내었으며, adiponectin은 연령과 양의 상관관계, 체질량지수와 음의 상관관계를 나타내었고, TNF-α는 공복혈당과, IL-6는 HOMA-IR과 유의한 양의 상관관계를 나타내었다. 호르몬 치료 6개월 후 hs-CRP는 치료 후 유의한 증가를 보였으나 (0.51±0.30 vs. 1.22±1.52 mg/L, P < 0.05), adiponectin, resistin, TNF-α, IL-6는 유의한 차이를 보이지 않았다.결론적으로, 건강한 여성에서 폐경 후 adipokine의 변화가 심혈관 질환 위험도와 대사성 증후군의 발현에 일차적인 원인이 되지 않으며, 폐경 여성의 경구 호르몬 단기 치료는 hs-CRP는 증가시키지만 adipokine에 영향을 미치지 않는다.

[영문]Recent research has demonstrated that adipose tissue is an active endocrine organ, which secretes various hormones, such as adiponectin, resistin, and leptin, referred to as adipo(cyto)kines. Adiponectin has anti- inflammatory, anti diabetic, and anti-atherogenic properties and resistin is known to increase insulin resistance. Adipokines are related to inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP), Interleukin (IL)-6, Tumor necrosis factor (TNF)-α. Adipose tissue is redistributed after menopause, and the risk of metabolic syndrome and cardiovascular events increases in postmenopausal women. Adipokines are considered to play an important role in this, but much is not known about the effects of menopause and hormone therapy on adipokines.The objectives of this study are to assess the changes of adipokines after menopause and effects of hormone therapy on adipokines and to evaluate the relations between cardiovascular risk factors and adipokines.Study subjects consisted of 36 premenopausal and 33 healthy, early menopausal women. 27 of the menopausal women received 6 months of hormone therapy. Initially body mass index (BMI), waist to hip ratio (WHR), and blood pressure (BP) were measured and lipid profile, fasting glucose, insulin, hs-CRP, IL-6, TNF-α, adiponectin, and resistin were assayed. Homeostasis model assessment of insulin resistance (HOMA-IR) index was calculated.Total cholesterol, HDL cholesterol and fasting glucose levels in menopausal women were significantly higher than premenopausal women (169.39±30.04 vs. 197.55±35.37 mg/dL, 53.94±10.54 vs. 59.99±11.55 mg/dL, 4.75±0.36 vs. 5.04±0.46 mmol/L, P < 0.05), but not HOMA-IR index. Adiponectin was significantly raised in menopausal women (4.56 ± 2.42 vs. 7.76 ± 4.99 µg/mL, P < 0.05), but no difference was observed in levels of resistin, hs-CRP, TNF-a, and IL-6. Through multivariate regression analysis, hs-CRP and BMI were positively correlated, and adiponectin was positively correlated with age, and negatively correlated with BMI. TNF-α was significantly correlated with fasting glucose, and IL-6 with HOMA-IR index. After 6 months of hormone therapy, hs-CRP increased significantly (0.51±0.30 vs.1.22±1.52 mg/L, P < 0.05), but levels of adiponectin, resistin, TNF-a, and IL-6 were not altered.In conclusion, since adiponectin levels in healthy menopausal women increase significantly, it doesn’t seem to play a primary role in developing cardiovascular events and metabolic syndrome in menopausal women. Short term hormone therapy in menopausal women didn’t affect the levels of adipokines. Even though hs-CRP, an inflammatory marker, was increased after short-term hormone therapy, homocysteine and insulin levels went down and lipid profile was improved.
