당뇨가 오래되면 삶의 질을 떨어뜨리는 여러 가지 합병증들이 오게 되는데 그 중에서 시력을 위협하는 제일 심각한 합병증은 당뇨망막병증으로 이는 망막에 영양을 공급하는 혈관이상에 의해 발생하는 진행성 질환이다. 당뇨망막병증의 발생빈도는 당뇨의 유병기간과 밀접한 관계가 있다. 당뇨로 진단받고 5$\sim$10년이 지나면 25$\sim$50%가 망막병증이 생기고 15년이 지나면 거의 90%환자가 망막병증이 생긴다. 이밖에도 고혈압, 임신, 신장질환, 고지혈증과 같은 위험인자들이 있으며 어린이나 사춘기에 당뇨병이 있는 경우에는 조기에 망막병증의 빈도가 매우 높게 나타난다.

Objectives: The purpose of this study was to analyze the influence of four lifestyle-related diseases, diabetes, hypertension, obesity and hypercholesterolemia, on oral health in the rural elderly in Korea. Methods: We enrolled 399 subjects over 60 years of age over a six year period, year 2000-2006/ year 2001-2007. All subjects received a routine health examination as part of a program conducted by the National Health Insurance Corporation at Seongju-gun Public Health Center in Gyeongsangbuk-do Province, South Korea. All subjects were surveyed and examined to determine their general and oral health statuses. Results: Our results suggest that the duration of lifestyle-related diseases has a significant influence on oral health. The following factors were all significant in the results of analyses: duration of diabetes, tooth decay, which teeth had decayed, missing and filled teeth(DMFT), duration of hypertension, and duration of obesity and hypercholesterolemia(p<0.05). Our results also suggest that the number of lifestyle related diseases has a significant influence on oral health. Subjects with more than two diseases had significantly greater numbers of missing teeth and greater numbers of DMFT(p<0.01). The results of simple regression analysis indicate that patients exhibiting longer durations of diabetes also exhibit more tooth decay, and that patients exhibiting longer durations of hypertension and obesity are characterized by greater numbers of missing teeth. The longer the duration of any of the four lifestyle-related diseases we considered, the more DMFT we observed. Multiple regression analyses also demonstrated that longer duration of lifestyle-related disease was associated with greater numbers of missing teeth. As the number of lifestyle-related diseases increased, DMFT also increased. Conclusions: In summary, lifestyle-related diseases such as diabetes, hypertension, obesity and hypercholesterolemia have significant influences on oral health in the elderly. In this context, the prevention and management of lifestyle-related disease is critical for the maintenance and promotion of oral health.

대혈관 합병증은 중간크기 이상의 혈관(동맥 및 정맥)에서 동맥경화증이나 죽상경화증에 의한 변화로 발생하는 질환으로 관상동맥, 뇌혈관 및 말초혈관에 주로 발생하며 당뇨병환자의 주된 사망원인과 관련이 있기 때문에 매우 중요합니다. 당뇨병환자에서 대혈관 합병증인 죽상경화증은 가장 흔하고 중대한 만성합병증으로 관상동맥질환에 의한 관상동맥질환, 말초혈관질환 및 뇌혈관질환이 발생합니다. 발생률은 당뇨병이 없는 사람에 비해 2$\sim$5배 높으며 제 2형 당뇨병뿐만 아니라 제 1형 당뇨병환자의 주된 사망원인이 됩니다. 대혈관 합병증과 관련된 질환은 유병기간이 오래된 당뇨병환자에서 이환율, 장애 정도, 사망률 및 치료비용에 심각한 영향을 미칩니다. 당뇨병환자의 사망은 대부분이 대혈관 합병증과 관련이 있으며, 이중에서도 관상동맥질환으로 인한 사망률이 2$\sim$4배 증가합니다. 당뇨병성 만성합병증은 건강관리를 위한 지출에 상당히 영향을 미칩니다. 총 의료관리 예산의 약 25%가 당뇨병 및 당뇨병성 만성합병증의 치료에 지출됩니다. 위험요소를 감소시키거나 제거하면 만성합병증의 85%가 지연되거나 진행을 늦출 수 있습니다. 이것으로 미국의 경우 매년 170억 달러의 의료관리 예산을 절감할 수 있다고 합니다.

우리나라의 당뇨병 유병률은 경제발전과 식생활의 급속한 서구화로 빠른 속도로 증가하고 있다. 특히 당뇨병은 유병기간이 길수록 여러 합병증을 초래하는데 그 중 하나가 혈관경화증이다. 혈관 경화증은 신체 부위별로 그 진행 속도가 다르다. 광혈류측정법(PPG, photoplethysmogram)은 간편한 혈류량 측정방법으로 PPG 2차 미분 방법을 이용해서 혈관의 경화도를 진단할 수 있다. 이러한 PPG 2차 미분방법을 이용하여 당뇨병환자의 왼손과 오른손의 말초혈관 탄성도 차이를 정상인과 비교해 보았다. 실험결과 당뇨병환자와 정상인의 양 손가자 말초혈관 탄성도의 유의한 차이를 확인 할 수 있었다.

현재, 우리나라 당뇨병의 유병률은 빠른 속도로 증가하고 있으며 당뇨병의 유병기간이 길수록 각종 합병증이 발생하며 더욱 심각한 증세를 나타내기도 한다. 그 중, 비만 및 고혈당, 당대사장애로 인한 당뇨병성 혈관 합병증과 말초 혈관 경화증이 많이 발병하고 있는 실정이다. 본 연구에서는 광혈류량 측정법(Photoplethysmograaphy)으로 손가락에서 얻어진 맥파의 2차 미분 분석을 통해 당뇨병으로 확진된 36명의 당뇨병 환자에 대해 말초혈관 경화도를 연령별로 비교하고자 하였다. 이때 사용한 PPG 파형의 2차 미분 분석 평가 인자는 a와 d이고, d/a는 혈관의 경화도를 의미하며 경화도가 클수록 d/a의 값은 감소하게 되고, 연령이 증가할수록 경화도는 증가하게 된다. 50대 미만의 당뇨병 환자의 d/a값은 $-0.32{\pm}0.12$, 50대는 $-0.48{\pm}0.13$, 60대는 $-0.55{\pm}0.16$, 70대 이상에서는 $-0.59{\pm}0.19$로 연령이 높아질수록 d/a값이 감소하는 것을 확인하였다. 또한, SPSS 13.0 for Windows(SPSS Inc, USA)의 Oneway ANOVA 분석 결과, 연령과 경화도는 통계적으로 유의한 차이를 보였다(p<0.05). 하지만 70대 이상의 당뇨병 환자 그룹에서는 유의한 차이를 확인할 수 없었다. 본 연구에서는 PPG 파형의 2차 미분 분석을 통하여 연령별 당뇨병 환자의 말초혈판 경화도를 비교하였으며, 향후 보완 연구를 통해 비침습적이고 간단한 방법으로 당뇨병 환자의 말초혈관 경화도를 객관적으로 평가하고 진단할 수 있는 시스템 개발로 당뇨병 환자들의 심혈관계질환 사전예방과 치료효과 판정에 도움을 줄 것으로 기대한다.

This study identifies the factors influencing Quality of Life (QoL) in both male and female workers with diabetes mellitus and examines the differences between them. Using data from the Korea National Health and Nutrition Examination Survey (KNHANES) for 2010-2017, 1693 workers (1082 males; 611 females), aged 19 or over, with diabetes mellitus were enrolled in the study. Data were analyzed by complex sample linear regression using SPSS/WIN 23.0. The factors influencing QoL differed between males and females. The common factors included household income, education, job, stress, disease duration, and disease complications. The additional factors in males included working style, and, in females included age, marital status, drinking habits, and the treatment and control of the disease. Males had a higher QoL than females in all the sub-factors. Patients with diabetes mellitus require gender-specific intervention and governmental and social policies that can support it must be developed.

Purpose : This study analyzed the expression of HLA-DR and DQ genotypes and anti-thyroid autoantibodies[anti-thyroid peroxidase(TPO) and anti-thyroglobulin(TG) antibodies] in Korean patients with type 1 diabetes(T1DM) to investigate the susceptible HLA alleles to T1DM in Korea and the prevalence of thyroid autoantibodies and their significance for the development of thyroid disorders. Methods : A total of 59 Korean patients with type 1 diabetes[26 males, median age 13.7 years(range 5.7-29.9 years), diabetes duration 7.6 years(-1.7-22.5 years)] were enrolled in this study, and 200 healthy Koreans without a family history of diabetes were selected as a normal control for the comparison of HLA genotypes. Seventeen patients with anti-TPO or anti-TG were followed [median duration 3.96 years(1 day-10.7 years)] with measurement of anti-TPO, anti-TG, $T_3$, $T_4$ or free $T_4$, TSH levels and physical examinations. HLA-DR and DQ genotyping were done by PCR-SSO, PCR-SSCP, PCR-RFLP and PCR-SSP methods. Results : HLA analysis showed higher frequencies of HLA-DRB1*0301, *090102 and DQB1*0201, *030302 alleles, DRB1*0301/*090102, *090102/*090102 and DQB1 *0201/*030302, *030302/*030302, *0201/ *0302 genotypes in T1DM patients compared to controls(Pc<0.05). Fifteen(25.4 percent) had anti-TPO antibody, 12(20.3 percent) had anti-TG, 17(28.8 percent) had either autoantibody and 10(16.9 percent) had both autoantibodies. No clinical or subclinical hypothyroidism developed during follow-up after the first detection of anti-thyroid autoantibody. There was no significant correlation between thyroid autoimmunity and gender, onset age of T1DM, and diabetes duration, respectively(P>0.05). Conclusion : We thought this unique HLA-DR, DQ allele distribution might be an important factor for the low incidence of T1DM in Korea. And a high prevalence of thyroid autoantibodies in these populations suggests examinations of thyroid antibodies should be performed regularly. Optimal age for the initial screening and the frequency of re-screening for associated thyroid autoimmune diseases in T1DM remains to be determined through prospective follow-up.

Type 1 diabetes mellitus commonly occurs in childhood and adolescence, although the prevalence of type 2 diabetes mellitus in these age groups is now being increased in the western world and Korea. Diabetic nephropathy developing in 15-25% of subjects with type 1 diabetes mellitus and in similar or higher percentage of type 2 diabetes mellitus patients is the leading cause of end-stage renal disease worldwide. Although prepubertal diabetic duration may contribute less to the development of microvascular complications than pubertal and postpubertal duration, diabetic nephropathy in susceptible patients almost certainly begins soon after disease onset and may accelerate during adolescence, leading to microalbuminuria or incipient DN. Type 1 diabetes is commonly associated with a period of hyperfiltration followed by the development of persistent microalbuminuria after as little as 7-10 years of type 1 diabetes. Microalbuminuria is associated with pathologic lesions that are so advanced as to overlap with those seen in patients with overt proteinuria and declining kidney function, therefore, microalbuminuria currently considered the best clinical indicator of overt diabetic nephropathy risk. This review covers the natural history and renal manifestations of diabetic nephropathy in children and adolescents.

In diabetes mellitus, renal disease is a common complication, characterized by increased urinary albumin excretion and reduced eGFR. According to KDIGO CKD stage classification, Korean characteristics were analyzed according to urinary albumin and eGFR using the National Health and Nutrition Examination Survey VI raw data. According to KDIGO classification, diabetic patients were classified as Low risk 72.0%, Moderate risk 19.3%, High risk 5.6% and Very high risk 3.0%. Low risk decreased from 74.7% to 52.2%, and moderate to very high risk increased from 25.4% to 47.8% as the duration of diabetes mellitus was prolonged. The risk factors were CKD stage 1 (HR 2.064) to stage 4 (HR 11.049), the highest risk of hypertension. The incidence of renal disease was elevated according to duration of hypertension and HR 0.42 of kidney disease was decreased in the group maintaining proper blood pressure. In the hypertensive patients, the group administered with target blood pressure had a reduction of the kidney disease by 42% than the group with the hypertension. Therefore, controlling and managing hypertension to target blood pressure is important for the prevention of kidney disease.
