Background/Aims: This study aimed to investigate whether the apolipoprotein (Apo) B/ApoA-I ratio is associated with carotid intima-media thickness (CIMT) in type 2 diabetes mellitus (T2DM) subjects with low density lipoprotein cholesterol (LDL-C) levels less than 100 mg/dL. Methods: This cross-sectional study included 845 subjects aged with T2DM 40 to 75 years who had visited Huh’s Diabetes Center in Seoul, Republic of Korea for CIMT measurement. Traditional fasting lipid profiles, ApoB and ApoA-I levels were examined. CIMT was measured at three points on the far wall of 1 cm long section of the common carotid artery in the proximity of the carotid bulb. The mean value of six measurements from right and left carotid arteries were used as the mean CIMT. In this study, carotid atherosclerosis was defined as having a focal plaque or diffuse thickening of the carotid wall (mean CIMT ≥ 1.0 mm) Results: The prevalence of carotid atherosclerosis increased with ApoB/ApoA-I ratio. The ApoB/ApoA-I ratio, expressed as both quartiles (odds ratio [OR], 2.14; 95% confidence interval [CI], 1.21 to 3.79; p for trend = 0.014) and continuous values (OR, 10.05; 95% CI, 3.26 to 30.97; p < 0.001), was significantly associated with a higher risk for carotid atherosclerosis, regardless of conventional cardiovascular disease risk factors. The optimal ApoB/ApoA-I ratio cutoff value for detecting carotid atherosclerosis was 0.57, based on receiver operating characteristic curve analysis with a sensitivity of 58.0% and a specificity of 55.1%. Conclusions: A high ApoB/ApoA-I ratio was significantly associated with carotid atherosclerosis in T2DM patients with LDL-C levels less than 100 mg/dL.

Objectives: Abdominal obesity increases mortality and morbidity from cardiovascular disease and there is a possibility that smoking effects obesity. However, previous studies concerning the effects of smoking on obesity are inconsistent. The objective of this study was to examine whether smoking is positively related to abdominal obesity in men with type 2 diabetes. Methods: Subjects consisted of 2197 type 2 diabetic patients who visited Huh's Diabetes Center from 2003 to 2009. Indices of abdominal obesity were defined as visceral fat thickness (VFT) measured by ultrasonography and waist circumference (WC). Overall obesity was defined as body mass index (BMI). Results: Statistically significant differences in WC and VFT by smoking status were identified. However, there was no statistical difference in BMI according to smoking status. Means of WC and VFT were not significantly higher in heavy smokers and lower in mild smokers. Compared to nonsmokers, the BMI confounder adjusted odds ratio and 95% confidence interval for VFT in ex-smokers and current-smokers were 1.70 (1.21 to 2.39) and 1.86 (1.27 to 2.73), respectively. Conclusions: Smoking status was positively associated with abdominal obesity in type 2 diabetic patients.

BACKGROUND/OBJECTIVES: This study was performed to investigate the association between the dietary intake of fish and shellfish, and omega-3 polyunsaturated fatty acids (PUFAs) and cardiovascular disease (CVD) risk factors in the middle-aged Korean female patients with Type 2 diabetes (T2D). SUBJECTS/METHODS: A cross-sectional analysis was performed with 356 female patients (means age: 55.5 years), who were recruited from the Huh’s Diabetes Clinic in Seoul, Korea between 2005 and 2011. The dietary intake was assessed by a validated semi-quantitative food frequency questionnaire and analyzed using the Computer Aided Nutritional Analysis program (CAN-Pro) version 4.0 software. RESULTS: In a multiple regression analysis after the adjustment for confounding factors such as age, BMI, duration of diagnosed T2D, alcohol consumption, fiber intake, sodium intake, and total energy intake, fish and shellfish intake of the subjects was negatively associated with triglyceride and pulse wave velocity (PWV). Omega-3 PUFAs intake was negatively associated with triglyceride, systolic blood pressures, diastolic blood pressures, and PWV. The multiple logistic regression analysis with the covariates showed a significant inverse relationship between the omega-3 PUFAs consumption and prevalence of hypertriglyceridemia [OR (95% CI) for greater than the median compared to less than the median: 0.395 (0.207-0.753)]. CONCLUSIONS: These results suggest that the consumption of fish and shellfish, good sources of omega-3 PUFAs, may reduce the risk factors for CVD in the middle-aged female patients with T2D.

BACKGROUND/OBJECTIVES: This study was aimed at examining the association between dietary flavanones intake and lipid profiles according to the presence of metabolic syndrome (MetS) in Korean women with type 2 diabetes mellitus (T2DM). SUBJECTS/METHODS: A cross-sectional analysis was performed among 502 female T2DM patients (non-MetS group; n = 129, MetS group; n = 373) who were recruited from the Huh’s Diabetes Clinic in Seoul, Korea between 2005 and 2011. The dietary intake was assessed by a validated semi-quantitative food frequency questionnaire (FFQ) and the data was analyzed using the Computer Aided Nutritional Analysis program (CAN-Pro) version 4.0 software. The intake of flavanones was estimated on the basis of the flavonoid database. RESULTS: In the multiple linear regression analysis after adjustment for confounding factors, daily flavanones intake was negatively associated with CVD risk factors such as total cholesterol, LDL-cholesterol, and apoB and apoB/apoA1 ratio only in the MetS group but not in the non-MetS group. Multiple logistic regression analysis revealed that the odds ratio for a higher apoB/apoA1 ratio above the median (≥ 0.74) was significantly low in the 4th quartile compared to that in the 1st quartile of dietary flavanones intake [OR: 0.477, 95% CI: 0.255-0.894, P for trend = 0.0377] in the MetS group. CONCLUSIONS: Dietary flavanones intake was inversely associated with the apoB/apoA1 ratio, suggesting a potential protective effect of flavanones against CVD in T2DM women with MetS.

연구배경: Apolipoprotein B/apolipoprotein A-I 비율(ApoB/ApoA-I)은 대사증후군의 중요한 임상적 지표이다. 하지만, 한국인 제2형 당뇨병환자들을 대상으로 ApoB/ApoA-I과 대사증후군의 관련성을 살펴본 연구는 미미하다. 따라서 본 연구에서는 ApoB/ApoA-I과 ApoB/ApoA-I 사분위에 따른 대사증후군 및 대사증후군 각 요소별 위험도를 보았다. 방법: 대상자는 서울의 당뇨병 전문 클리닉 허내과를 방문한 제2형 당뇨병환자 812명 (남자 424명, 여자 388명)이다. 이들을 성별로 ApoB/ApoA-I의 사분위에 따라 네 군으로 나누었다(가장 낮은 군:Q1-가장 높은 군:Q4). 체위, 혈액성상 및 식품섭취 빈도조사지를 통한 식이섭취량이 측정되었다. 결과: 대사증후군의 유병률은 남자 47.9%, 여자 66.5%였다. 대사증후군과 대사증후군의 각 위험요소에 대한 OR은 남녀 모두 ApoB/ApoA-I의 Q2에서 Q4로 갈수록 유의하게 증가했다(남자: OR=5.37; 95% CI=2.98-9.65 and OR=7.41; 95% CI=4.04-13.6; 여자: OR=2.57; 95% CI=1.28-5.15 and OR=8.49; 95% CI=4.28-16.8). 이러한 경향은 남녀 모두에서 연령, 당뇨 유병기간, 공복 혈당, 대량영양소를 보정한 후에도 변하지 않았다(남자: OR=5.24; 95% CI=2.80-9.24 and OR=7.98; 95% CI=4.09-15.6; 여자: OR=3.54; 95% CI=1.84-6.81, OR=4.41; 95% CI=2.26-8.61, and OR=8.29; 95% CI=3.85-17.8). 결론: 본 연구에서는 당뇨병환자에서 가장 중요한 인자 중 하나인 다량 영양소 섭취량을 포함한 대사증후군의 위험요인을 보정하기 전과 후 모두 ApoB/ApoA-I이 증가 할수록 대사증후군 및 대사증후군 각 요소의 위험도가 증가했다. 향후, ApoB/ApoA-I 증가와 대사증후군 및 대사증후군 각 요소의 위험도에 대한 정확한 평가를 위해 ApoB/ApoA-I과 관련한 식이위험요인에 대한 전향적인 연구가 필요할 것으로 사료된다. Background: The Apolipoprotein B/apolipoprotein A-I ratio (apoB/apoA-I) is a powerful clinical indicator of metabolic syndrome. However, few studies have searched for an association between ApoB/ApoA-I and metabolic syndrome in Korean patients with type 2 diabetes. We investigated the relation between ApoB/ApoA-I and the risk of metabolic syndrome and its components. Methods: Subjects were 812 (424 males and 388 females) Korean patients who were being treated for type 2 diabetes at Huh`s Diabetes Center in Seoul. The patients were classified into quartiles (lowest:Q1- highest:Q4) of ApoB/ApoA-I by gender. Anthropometric and hematological characteristics and dietary intake using a food frequency questionnaire were assessed. Results: The prevalence of metabolic syndrome in our sample was 47.9% in males and 66.5% in females. The odds ratios (OR) for metabolic syndrome and for having its components were significantly increased from Q2 to Q4 quartiles of ApoB/ApoA-I in males (OR = 5.37; 95% CI = 2.98-9.65 and OR = 7.41; 95% CI = 4.04-13.6) and females (OR = 2.57; 95% CI = 1.28-5.15 and OR = 8.49; 95% CI = 4.28-16.8). These trends withstood adjustment for age, duration of type 2 diabetes, fasting blood glucose levels, and macronutrient intake both in males (OR = 5.24; 95% CI = 2.80-9.24 and OR = 7.98; 95% CI = 4.09-15.6) and in females (OR=4.41; 95% CI = 2.26-8.61 and OR = 8.29; 95% CI = 3.85-17.8). Conclusion: ApoB/ApoA-I appeared to be independently associated with risk of having metabolic syndrome and its components in Korean patients with type 2 diabetes after adjustment for putative risk factors including macronutrient intake, a particularly important lifestyle factor for patients with type 2 diabetes. A follow-up study of this population should evaluate the mechanisms underlying the relation between ApoB/ApoA-I and metabolic syndrome and its components. (Korean Diabetes J 33:143-154, 2009)
A Rapid PCR-based Assay for Detecting Hepatitis B Viral DNA Using GenSpector TMC-1000
Huh, Bum,Ha, Young-Ju,Oh, Jae-Tak,Park, Eun-Ha,Park, Jin-Su,Park, Hae-Joon The Korean Society for Applied Biological Chemistr 2006 Journal of Applied Biological Chemistry (J. Appl. Vol.49 No.4
A rapid PCR-based assay for detecting hepatitis B viral DNA(HBV DNA) in serum and plasma was developed using a new PCR instrument named GenSpector(TMC-1000, Samsung electronics). PCR was carried out using a chip-based platform, which enabled 50 PCR cycles with internal controls, and melting-curve analysis in 30 minutes. Verification of the amplified HBV DNA product and the internal control was based on specific melting temperatures(Tm) analysis, executed by the GenSpector software. Primers were designed within the region conserved through HBV genotypes A to F. The lower limit of detection was 840 copies/ml serum, conducted with serial dilutions of a HBV DNA positive control(ACCURUN 325 series 700, Boston Biomedica Inc.). The assay was also compared to another assay for HBV DNA(Versant HBV DNA 3.0 assay, Bayer HealthCare) for 200 samples(each 100 clinical negative and positive samples). The sensitivity and specificity were 100% matched. This rapid PCR-based assay is specific, reproducible, and enables qualitative detection of HBV DNA.
