배경: 대혈관 합병증은 당뇨병환자의 주요 사망 원인으로 미세혈관 합병증과는 달리 유병기간과 비례하지 않는다. 그러나 한국인에서 당뇨병성 대혈관 합병증 발생까지의 당뇨병의 평균 유병기간이나 합병증 발생과 관련된 예측 인자들에 대한 연구는 아직 많이 부족한 실정이다. 따라서 저자들은 제2형 당뇨병에서 대혈관 합병증 발생까지의 평균 유병기간과 대혈관 합병증 발생에 영향을 미치는 요인들, 특히 조기합병증 발생에 관여하는 위험요소들을 조사하고자 하였다. 방법: 대혈관 합병증이 처음 발생하여 입원한 121명의 환자와 대혈관 합병증의 과거력이 없는 115명의 제2형 당뇨병 입원환자를 대상으로 하여 임상적 특성을 후향적으로 조사, 분석하였다. 대혈관 합병증 발생까지의 당뇨병 이환 기간을 5년을 기준으로 조기발생군(54명)과 후기발생군(67명)으로 나누어 비교 분석하였다. 또한 대혈관 합병증 발생군을 성별에 따라 나누어 추가 분석을 시행하였다. 결과: 대혈관 합병증 발생까지의 평균 당뇨병 유병기간은 8.7±7.8년, 평균 연령은 61세, 남녀 각 63명, 58명이었다. 대혈관 합병증 발생군과 대조군과의 비교에서 평균 나이(61.0±11.8 vs. 56.0±14.6세, P=0.004), 수축기와 이완기 혈압 모두 대혈관 합병증 발생군에서 높았고(133.6±20.7/79.8±12.3 vs. 121.8±17.7/76.3±9.6 mm Hg, P<0.05), 흡연력이 있는 환자의 비율이 높았다(42.1 vs. 20.0%, P<0.001). 그러나 당화혈색소는 대조군에서 대혈관 합병증 발생군에 비해 더 높았고(9.5±2.4 vs. 8.2±1.8%, P<0.001), 미세혈관 합병증 동반율도 유의하게 더 높았다. 대혈관 합병증 조기발생군의 평균 연령이 후기발생군보다 더 적었으며(58.2±12.8 vs. 63.4±10.4세, P=0.015), 흡연력은 더 많았다(53.7 vs. 32.8%, P=0.021). 대혈관 합병증 발생군에서 성별에 따른 분석 결과, 남성에서 여성보다 합병증 발생 연령이 보다 적었고(57.5±10.3 vs. 64.9±12.2세, P<0.001), 당뇨병의 가족력이 남성에서 더 많았으며 흡연력은 남성에서 77.8%로 여성의 3.4%에 비해 매우 높았다. 결론: 본 연구를 통하여 제2형 당뇨병에서 대혈관 합병증발생에 고령, 고혈압, 그리고 흡연력이 중요한 위험 인자임을 알 수 있었고 대혈관 합병증 위험도는 미세혈관 합병증 발생 이전부터 높아져 있었다. 특히 흡연력은 한국인 남성 제2형 당뇨병환자에서 대혈관 합병증 조기 발생에 관여하는 중요한 예측 인자로 생각된다. 또한 추가 분석 결과를 미루어볼 때, 같은 당뇨병의 유병기간을 가졌다 하더라도 60세 미만의 상대적으로 젊은 나이의 당뇨병환자들이 고령의 환자들보다 대혈관 합병증 조기 발생 위험도가 상대적으로 높은 것으로 여겨지며, 대혈관 합병증 발생과 관련하여 성별에 따라 연령, 당뇨병의 가족력, 고혈압, 흡연력과 같은 몇 가지 위험 요소들의 차이점이 발견되었다. 이러한 결과들은 제2형 당뇨병환자에서 대혈관 합병증 발생 예방에 효과적으로 이용될 수 있을 것으로 생각된다. Background: The average duration of diabetes and predictive factors of macrovascular complications in Korean diabetic patients remain to be elucidated. This study examines the average duration of diabetes up to the onset of macrovascular complications and clinically important factors of early development of these complications in Korean type 2 diabetic patients. Methods: Clinical characteristics in type 2 diabetics with (n=121) and without macrovascular complications (n=115) were analyzed. In addition, early onset (≤5 years, n=54) and late onset groups (>5 years, n= 67) were compared, as were the clinical characteristics between male and female patients in the macrovascular complications group. Results: The average duration of diabetes was 8.7±7.8 years in the macrovascular complications group. Average age, systolic and diastolic blood pressures and smoking history were all higher in the macrovascular complications group than the control group. However, HbA1c levels and prevalence of microvascular complications were higher in the controls. Average age was lower in the early onset group and many more patients of that group had a smoking history. In the analysis based on sex, marcrovascular complications developed earlier in male patients. In addition, the prevalence of family history of diabetes was higher in males and 77.8% of male patients had a smoking history (female: 3.4%). Conclusion: Our study confirms that older age, high blood pressure and smoking history are major risk factors for the development of macrovascular complications. Moreover, a smoking history in males can be both risk and predictive factors for earlier development of macrovascular complications in Korean type 2 diabetic patients. We also found that several clinical characteristics including age, family history of diabetes, hypertension and smoking history, vary between the sexes, and these findings can provide useful indices for the prevention of macrovascular complications.

Backgroud: DHEA-S is the most abundant steroid hormone in circulation, and primarily secreted from the adrenal cortex, but its physiological role is little known. One of the characteristic features of DHEA-S is progressive decrement of plasma DHEA-S level with advancing age, in contrast, plasma levels of other adrenal hormones are not chaging or littie decreasing. To grasp the trends of plasma DHEA-S level and DHEA-S/cortisol ratio by age in healthy Korean, we measured the plasma DHEA-S levels and DHEA-S/cortisol ratios in healthy Korean. Methods: Healthy Korean(men: 99, women: 102, age range: 15-97 year old)were studied. Subjects were not taking drugs(such as glucocorticoid or androgenic medication) or cigarettes known to modify the plasma level of DHEA-S and cortisol, and had no evidence of hepatic, renal disease or hyperlipidemia as determined by serum lipid, bilirubin, SGOT, SGPT, BUN, creatinine. Data were analyzed by 10-year age group for men and women: i.e, 10-19, 20-29, 30-39, 40- 49, 50-59, 60-69, 70-79, 80-89 and 90 year or more. Plasma DHEA-S levels were measured by using a commercially available RIA kit with 125I labeled-DHEA-SO4(Coat-A Count DHEA-SO4), and for the measurement of plasma cortisol levels, commercial Gamma Coat TM[125I] Cortisol Radioimmunassay Kit was used. Results:. 1) In both men and women, plasma DHEA-S level showed high interindividual variation within the same age group. 2) There were individual sex differences in plasma levels of DHEA-S, in all age groups, plasma DHEA-S levels were significantly higher values for men than for women. 3) Maximum plasma DHEA-S levels(men; 237+-3.35 ug/dL, women; 108+-17.5 ug/dL) were at third decade in both men and women. 4) Both men and women showed the continuous decline in plasma DHEA-S level with age. These age-related decline was more prominent in men than in women(men; y= -3.152 * +292.6, r2= 0.8459, P$lt;0.05, women; y= -1.417 * +143.3, r2 = 0.7278, P$lt; 0.05). 5) As an index of aging, there was no stastical difference between DHEA-S and DHEA- S/cortisol ratio. Conclusion: In healthy Korean, there were high interindividual variation of plasrna DHEA-S levels. In both men and women plasma DHEA-S level was peak at third decade, and from when it declined progressively with age. These results suggest that although the reliability of single plasma DHEA-S measurement are limited, the decline of DHEA-S with advancing age might be a specific marker of endocrinologic hormonal milieu(aging index). Also, concerning to individual adrenal secreting capacity, we measured DHEA-S/cortisol ratio. But we did not found that plasma DHEA-S/cortisol ratio is superior to the plasma DHEA-S level as an aging index. (J Kor Soc Endocrinol 12:245-254, 1997)

Chronic heavy use of phosphate-binding antacids has been known to cause osteomalacia. However, ira spite of widespread use of antacids without prescription, there was no case report of osteomalacia associated with antacids in Korea. We report a case of osteomalacia diagnosed in a 36-year-old woman who had ingested large amounts of aluminum-containing antacids due to epigastric soreness. She had consumed about 4.2 kg of aluminum hydroxide over 10 years until she had withdrawn antacids 3 months before she was admitted with non-traumatic fractures of bilateral femur necks. Biochemical tests revealed normal levels of serum calcium and iPTH, increased level of serum alkaline phosphatase, and normal renal function. Bone mineral density (BMD) values of lumbar spines were decreased (T-score=-3.99~-3.11). Bone biopsy showed abundant unmineralized osteoid indicating osteomalacia. She was treated with bilateral total hip replacement arthroplasty and recommended not to restart the ingestion of antacids. After thirty months withdrawal of antacids, BMD values of lumbar spines were found to be improved (T-score=-2.3~-1.4). (Korean J Med 61:%-103, 2001)
