RESUMO
BACKGROUND/AIMS: Three different apo E alleles (E2, E3 and E4) produce apo E isoproteins, which regulate the metabolism of lipoproteins. This study investigated the apo E polymorphisms as a prognostic factor for the development of diabetic nephropathy (DN). METHODS: A total of 525 type 2 diabetic patients were enrolled to participate in this prospective observational study. Apo E gene polymorphisms were analyzed by polymerase chain reaction. The progression of DN was defined as a shift to a higher stage of DN or a doubling of the baseline serum creatinine level by the end of the study. RESULTS: The mean follow-up period was 42.4 months. The patients whose DN progressed had significantly higher urine albumin/creatinine ratios and fewer used diuretics than those in whom DN did not progress. In the Cox regression analysis, the apo E4 carriers were found to be at greater risk of progression of DN than non-apo E4 carriers (p = 0.007, hazard ratio 2.252). After adjusting for confounding factors, apo E4 carriers remained at increased risk of progression to more severe DN (p = 0.002, hazard ratio 2.820). CONCLUSION: Our study suggests the apo E4 carrier might serve as a predictor of DN progression in Taiwan.

BACKGROUND: We investigated the gender differences in the effect of ACE I/D and AGT M235T polymorphisms on the prognosis of diabetic nephropathy (DN). METHODS: A total of 525 type 2 diabetics were enrolled to participate in this prospective observational study. ACE and AGT gene polymorphisms were analyzed by polymerase chain reaction. The progression of DN was defined as a shift to a higher stage of DN or a doubling of the baseline serum creatinine level by the end of the study. RESULTS: The baseline biophysical parameters show no gender differences in progression and non-progression of DN. The women who were ACE D allele carriers were found to be at an increased risk of DN progression compared to those with II genotypes (p = 0.024, OR 2.176). No such difference was seen in male patients (p = 0.619, OR 0.833). After adjusting for confounding factors (age, SBP, DBP, BMI, HbA1c, total cholesterol, TG, HDL-C, LDL-C, ACEI, and ARB) in our multiple regression analysis, these women were still found to be at increased risk of progressing to more severe DN (p = 0.008, OR 3.082) but not the men (p = 0.183, OR 0.586). Neither the AGT TT genotype nor the T allele were associated with the progression of DN in either sex after adjusting for confounding factors. CONCLUSION: Our follow-up study suggests that female diabetic carriers of the ACE D allele might be at an increased risk of DN progression.

BACKGROUND: Chronic kidney disease (CKD) is associated with cardiovascular disease (CVD) in the general population. We investigated the effects of renal function on coronary artery disease (CAD) in Chinese with type 2 diabetes who have a high risk of developing diabetic nephropathy but who may have a low risk of developing CAD. METHODS: We recruited a total of 2,434 Chinese with type 2 diabetes (1,078 men and 1,356 women) and diagnosed CAD by history or with an abnormal electrocardiogram (coronary probable or possible by Minnesota codes). Renal function was evaluated by serum creatinine (SCr) levels, estimated glomerular filtration rate (eGFR) (calculated by the abbreviated Modification of Diet in Renal Disease Study Croup formula) and urinary albumin/creatinine ratio (ACR). RESULTS: We found that patients with CAD were older, had higher SCr levels and body mass index (BMI), and had lower serum high-density lipoprotein cholesterol (HDL-c) levels. After adjusting for age, BMI, blood pressure, glycosylated hemoglobin, cholesterol, LDL-c, HDL-c, and triglycerides, we found that SCr levels >1.5 mg/dl, eGFR <60 ml/min, and urinary ACR >30 mg/g were independent risk factors for CAD in diabetic men, and that SCr levels >1.4 mg/dl and eGFR <60 ml/min were independently associated with CAD in women. CONCLUSION: Our findings indicate that Chinese with type 2 diabetes and CKD are likely to have had CAD previously and CKD is 'CVD risk state' in diabetic Chinese.

This study investigates whether Tg gene polymorphisms can be associated with Graves' disease (GD) in a Taiwanese population and identifies potential polygenic susceptive genes for GD. The findings of such a study may have important implications for prognostic prediction and treatment of GD. We performed case control association studies for the 3 discovered Tg single nucleotide polymorphisms (SNPs) (E10, E12, E33) in 215 GD patients and 141 controls. The three SNPs were identified within the Tg gene. These SNPs were analysed by a fluorescent-based restriction fragment length polymorphism method (RFLP) and PCR. The genotype and allele frequencies at E10SNP158, E12SNP and E33SNP in GD patients were compared with those of the controls. In addition, we analysed the interactions between these SNPs and the clinical and laboratory variables. We found a significant difference in the T/T genotype of E33SNP and G/G genotype of E12SNP compared with the control group (p<0.001). We also found the E33SNP T/T genotype to be positively associated with development of GD, whereas the E12SNP G/G genotype protected it.

A single nucleotide polymorphism (SNP) located at position-1 in the Kozak sequence of the CD40 gene has been associated with the development of GD in Caucasian and Koreans. This study investigated possible associated between CD40 SNP and the development of GD in a Taiwanese population. To do this, we enrolled 215 Taiwanese patients with GD and 141 controls from the Endocrine Clinic of Kaohsiung Medical University Hospital. This study investigated the association between gene polymorphism and relapse of hyperthyroidism after the discontinuation of medication in three GD patient groups based on time to relapse and a control group, and compared clinical and laboratory data of patients regrouped in three CD40 SNP genotypes. No significant difference in allele or CD40 SNP genotype frequency was observed between patients with GD and control subjects (P = 0.859 and P = 0.959, respectively). Furthermore, we analyzed the distribution of CD40 genotypes and three groups based on time to relapse after drug withdrawal. The cutoff points were 9 months, 9 months to 3 years, and more than 3 yr in subgroups of patients with GD divided by clinical and laboratory variables. Although no significant genotype-phenotype associations were found, the T allele and TT genotype frequency was significantly smaller in GD patients who had developed the disease before 35 years old than those who developed it after 35 years old (x (2) = 6.272, P = 0.043) (TT + CT v.s. CC, x (2) = 4.951, P = 0.030). These findings suggest that this CD40 gene polymorphism is not associated with GD in Taiwan and is, therefore, not contributing to susceptibility to the disease there.

CONTEXT: Graves' disease (GD) is an autoimmune disorder with genetic predisposition. The thyroglobulin (Tg) is a major autoantigen for GD. The human Tg gene polymorphism has specific features that make it important in GD. OBJECTIVE: This study investigated whether Tg single nucleotide polymorphisms (SNPs) relate to GD development in a Taiwanese population. DESIGN AND SETTING: This was a case-control association study. PATIENTS AND MAIN OUTCOME MEASURES: We enrolled 215 Taiwanese patients with GD and 141 controls from the Endocrine Clinic of Kaohsiung Medical University Chung-Ho Memorial Hospital. This study investigated the association between gene polymorphism and relapse of hyperthyroidism after medication was discontinued in three GD patient groups and a control group. We also compared clinical and laboratory data obtained from patients with the three different genotypes with the three different Tg SNPs (E10SNP158, E12SNP, and E33SNP). RESULTS: We found a significant increase in the T/T genotype of E33SNP compared with the control group (P < 0.001). We also found the E33SNP C/C genotype of the Tg gene was strongly associated with a subgroup of GD patients who were also characterized as having a higher relapse rate, significantly higher levels of persisting TSH-receptor antibody at the end of treatment, a higher frequency in smoking, and a higher incidence of ophthalmopathy (P < 0.05). CONCLUSIONS: This study showed that Taiwanese patients with the C/C genotype of E33SNP, smoking, ophthalmopathy, and positive TSH-receptor antibodies at the end of the treatment were more likely to have a relapse of Graves' hyperthyroidism after antithyroid medication is withdrawn.

Diabetes is known to be a high-risk factor for coronary artery disease (CAD), and lipid abnormalities have been found to possibly contribute to CAD in diabetic patients. Cholesteryl ester transfer protein (CETP) gene TaqIB polymorphism is associated with lipid profile variability, and this polymorphism may be a risk factor for CAD in diabetic patients. To clarify the relationship between CETP TaqIB gene polymorphism and CAD, we enrolled in our study 365 Taiwanese with type 2 diabetes mellitus (101 with CAD and 264 without CAD). The genotype of the subjects for TaqIB polymorphism of CETP in intron 1 was analyzed by using polymerase chain reaction-restriction fragment length polymorphism. The CETP B1B1 genotype (18.8% vs 8.5%, P = .002) and B1 allele (42.1% vs 29.7%, P = .002) were significantly more frequent in diabetic patients with CAD than those without CAD. Logistic regression analysis revealed that the CETP B1B1 genotype was associated with CAD in patients with type 2 diabetes mellitus (odds ratio, 3.18; 95% confidence interval, 1.54-6.54; P = .002). Interestingly, in diabetic patients, serum creatinine levels higher than 1.4 mg/dL were also associated with increased risk for CAD (odds ratio, 2.09; 95% confidence interval, 1.12-3.91; P = .02). Our results suggest that the CETP B1B1 genotype is a strong genetic predictor of CAD in Taiwanese with type 2 diabetes mellitus.

Thyroid gland suppuration is a rare condition with nonspecific features. For this reason, diagnosis is often delayed, which may lead to a life-threatening situation. Causative agents are often gram-positive bacteria, such as Staphylococcus aureus and Streptococcus pneumoniae. With appropriate antibiotics and drainage of the abscess, the prognosis is usually excellent. Herein, we describe a unique case of acute suppurative thyroiditis in an adult male presenting with nonspecific sore throat after a fish bone injury to the throat. The patient had a history of essential hypertension and gouty arthritis. In the emergency room, fever, chills, and neck swelling were noted. Thyroid echo and computed tomography of the neck revealed the thyroid abscess with deep neck infection. The culture of the abscess showed Streptococcus viridans. He recovered gradually after parenteral antibiotics and surgical intervention.

Osteoprotegerin (OPG) and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) have recently been reported to be associated with diabetic nephropathy in an in vitro study. However, the literature regarding serum OPG and TRAIL in type 2 diabetes mellitus patients is scarce. To investigate the role of OPG/TRAIL in diabetic nephropathy, we measured the serum concentrations of OPG and TRAIL in type 2 diabetes mellitus patients with different stages of nephropathy by enzyme-linked immunosorbent assay. One hundred seventy-nine subjects with type 2 diabetes mellitus were studied and stratified according to urinary microalbumin and serum creatinine measurements. The serum concentrations of OPG and TRAIL were significantly elevated in patients with microalbuminuria (OPG, 2154.2 ± 922.1 pg/mL; TRAIL, 80.2 ± 24.1 pg/mL) and macroalbuminuria (OPG, 2251.5 ± 925.7 pg/mL; TRAIL, 88.1 ± 23.8 pg/mL) as compared with patients with normoalbuminuria (OPG, 1690.1 ± 627.2 pg/mL; TRAIL, 70.7 ± 23.3 pg/mL). Serum OPG and TRAIL levels were increased in parallel and were significantly associated with each other. Using multivariate stepwise regression analysis, serum OPG was found to be an independent factor associated with the severity of diabetic nephropathy. Our results suggested that serum OPG may be a marker for the severity of diabetic nephropathy. Further studies are necessary to investigate the role of elevated serum OPG in the pathogenesis of diabetic nephropathy.

BACKGROUND: No study to date has evaluated whether multifactorial intervention can prevent diabetic nephropathy in patients with type 2 diabetes mellitus and normoalbuminuria. We evaluated the effect of tightly controlling multiple factors recommended by the American Diabetes Association (ADA) on the development and prevention of diabetic nephropathy in Chinese patients with type 2 diabetes mellitus and normoalbuminuria during a 4(1/2)-year period. METHODS: A longitudinal cohort study enrolled 1290 patients with type 2 diabetes and normoalbuminuria who received intensified treatment to meet the following ADA recommended goals: hemoglobin A(1c )(HbA(1c)), less than 7%; systolic blood pressure, less than 130 mm Hg; diastolic blood pressure, less than 80 mm Hg; low-density lipoprotein cholesterol, less than 100 mg/dL; triglycerides, less than 150 mg/dL; and high-density lipoprotein cholesterol, greater than 40 mg/dL for men and greater than 50 mg/dL for women. RESULTS: During the study period, 211 patients (16.4%) developed new-onset microalbuminuria. A significant association was found between the achievement of ADA goals, including HbA(1c) level less than 7% (hazard ratio [HR], 0.729; 95% confidence interval [CI], 0.553-0.906; P = .03), systolic blood pressure less than 130 mm Hg (0.645; 0.491-0.848; P = .002), and high-density lipoprotein cholesterol level greater than 50 mg/dL for women and greater than 40 mg/dL for men (0.715; 0.537-0.951; P = .02) and the development of new-onset microalbuminuria. CONCLUSIONS: Diabetic nephropathy can be delayed by tight simultaneous achievement of multiple ADA-recommended targets. This multifactorial intervention should be started in patients with diabetes and normoalbuminuria.

We investigated the effects of the common polymorphisms in the peroxisome proliferator-activated receptor-gamma (PPAR-gamma; Pro12Ala) and in PPAR-gamma coactivator-1(PGC-1; Gly482Ser) genes on the response to pioglitazone in Chinese with type 2 diabetes mellitus. A total of 250 patients with type 2 diabetes mellitus were treated with pioglitazone (30 mg/d) for 24 weeks without a change in previous medications. All patients were genotyped for the PPAR-gamma Pro12Ala and PGC-1 Gly482Ser polymorphisms. The Ala12Ala and Pro12Ala genotypes (26.0% vs 13.5%, P = .025) and Ala allele (15.6% vs 7.3%, P = .008) were significantly more frequent in pioglitazone responders than in nonresponders. The distribution of PGC-1 genotypes and alleles was not significantly different between responders and nonresponders. The decrease in fasting glucose (50.4 +/- 52.2 vs 43.3 +/- 51.7 mg/dL, P < .001) and hemoglobin A(1c) (0.57% +/- 1.44% vs 0.35% +/- 1.10%, P = .004) levels was significantly greater in subjects with the Ala12 carriers (Pro12Ala and Ala12Ala) than in those without the allele (Pro12Pro). Baseline fasting glucose and triglyceride levels were related to the response of pioglitazone. Only the PPAR-gamma Pro12Ala polymorphism was found to be associated with the response of pioglitazone by multiple logistic regression analysis. The PPAR-gamma Pro12Ala gene polymorphism is associated with the response to pioglitazone in Chinese patients with type 2 diabetes mellitus. These findings may be helpful for targeted treatment of diabetes by identifying patients who are likely to respond to pioglitazone.

The risk for peripheral arterial disease (PAD) is increased in patients with chronic kidney disease. We investigated the effects of renal function on PAD in Chinese with type 2 diabetes mellitus. This study enrolled a total of 2983 (1342 men and 1641 women) Chinese adults with diabetes. The mean age was 63.2 +/- 11.9 years. Peripheral arterial disease was diagnosed by an ankle-brachial index less than 0.9. Renal function was evaluated by serum creatinine (SCr), estimated glomerular filtration rate, and urinary albumin-creatinine ratio (ACR). Risk factors for PAD were evaluated using multiple logistic regression analysis. Age, cholesterol, and high-density lipoprotein cholesterol (HDL-C) (inverse association) were significant risk factors in men, whereas age, body mass index (inverse association), low-density lipoprotein cholesterol, and HDL-C (inverse association) were significant risk factors for diabetic women. After adjustment for age, body mass index, blood pressure, glycosylated hemoglobin, cholesterol, HDL-C, low-density lipoprotein cholesterol, and triglyceride levels, we found that SCr levels greater than 1.5 mg/dL, estimated glomerular filtration rate less than 60 mL/min, and urinary ACR greater than 30 mg/g were independent risk factors for PAD in diabetic men and that SCr levels greater than 1.4 mg/dL and urinary ACR greater than 30 mg/g were independently associated with PAD in diabetic women. The risk factors for PAD are somewhat different between men and women with diabetes in Chinese population in Taiwan. Diabetic nephropathy is significantly associated with PAD in this patient population.

OBJECTIVE: Graves' disease (GD) is known to be associated with thyroglobulin (TG) and CD40 genes. Therefore, we decided to investigate the relationship of age at onset of GD with CD40 and TG gene susceptibilities in a Taiwanese population. DESIGN AND METHOD: We analyzed the association of TG and CD40 polymorphisms with age at onset of GD in Taiwanese patients. We stratified patients into those with early onset (<40 years; 30.3+/-4.8 years; n=135) and later onset (>or=40 years; 52.3+/-6.3 years; n=80) and compared the results with those of 141 normal controls. RESULTS: We found a significant statistical difference in the T/T genotype frequency of E33 single nucleotide polymorphism (SNP) and G/G genotype frequency of E12 SNP when compared with the control group (P<0.001). In addition, the frequencies of the T allele and TT genotype of the CD40 SNP were found to be significantly increased in GD patients who developed GD aged over 40 years than those below 40 years (allele: chi(2)=5.299, P=0.021, OR=1.597; genotype: chi(2)=6.168, P=0.046). By contrast, the frequencies of genotypes in the TG gene E10, E12, and E33 SNPs were not found to be significantly different in GD patients who developed GD when aged over 40 years when compared with those aged below 40 years. CONCLUSIONS: These data suggest that the T/T genotype and T allele in the CD40 gene are more likely to be associated with late-onset GD in Taiwanese patients.

OBJECTIVE: To assess continuing diabetic education in Taiwan, we evaluated the impact of comprehensive diabetes care program for Taiwanese people with type 2 diabetes. METHODS: 211 diabetic patients were enrolled and followed up for 1 year at Kaohsiung Medical University Hospital. Patients were provided comprehensive care and their medications were not changed. Clinical and biophysical variables were collected and assessed at 0, 3, 6, 9, 12 months. RESULTS: Metabolic control had improved significantly by 1 year: fasting plasma glucose (164.6+/-60.4 vs. 137+/-37.5mg/dl, p<0.001); total serum cholesterol (198.7+/-38.8 vs. 187.2+/-43.1mg/dl, p<0.001); high-density lipoproteins cholesterol (43.2+/-10.2 vs. 46.2+/-11.7 mg/dl, p<0.001); low-density lipoproteins cholesterol (121.1+/-32.9 vs. 113.1+/-29.6 mg/dl, p<0.005). In the male group, HbA1c level fell from 8.16+/-1.99% to 7.61+/-1.31% and 7.72+/-1.40% after 9 months and 1 year, respectively, p<0.05. There were also significant improvements in female group after 6 months and 9 months (7.89+/-1.62% after 6 months; 7.94+/-1.66% after 9 months vs. 8.22+/-1.70% at baseline). The change of HbA1c level was significant in male patients, patients whose duration of disease was shorter and in those with higher baseline HbA1c levels after multi-variable and age-adjusted analysis. CONCLUSION: The comprehensive diabetes care program effectively improved glycemic and cholesterol control. The patients who were more likely to achieve better glycemic control were male, had diabetes for shorter periods of time and had high baseline HbA1c levels. Therefore, diabetic education should be offered to patients as close to the time of diagnosis as possible.

BACKGROUND: Onychomycosis is a complication of diabetes mellitus (DM), which has a deleterious impact on the quality of life. Aim To explore the prevalence of onychomycosis amongst Taiwanese diabetics, and to analyze the factors associated with onychomycosis after adjusting for age and sex. METHODS: A total of 1245 Taiwanese diabetics were enrolled, and a nested case-control study was performed by onychomycosis outcome and the exposures were compared. RESULTS: The overall prevalence of onychomycosis among DM patients was 30.76% (383/1245), with a significantly higher prevalence in men than in women (P = 0.024). The factors associated with onychomycosis in matched pairs by gender and age were analyzed in 375 pairs. It was found that metabolic syndrome, obesity, triglyceride (TG) levels, and glycosylated hemoglobin (HbA1c) were associated with onychomycosis (P < 0.05). CONCLUSION: Higher prevalence rates of onychomycosis were found in men and older DM patients. Metabolic syndrome, obesity, high TG levels, and poor glycemic control were associated with onychomycosis.

Some studies have reported a possible relationship between endothelial nitric oxide synthase (eNOS) and metabolic syndrome (MS), which is associated with an increased risk for cardiovascular disease. A recent meta-analysis study found the eNOS G894T polymorphism to be associated with ischemic heart disease. Here, we examine the association of eNOS G894T polymorphism with MS in a Chinese population (n = 397). The eNOS T+ (TT and GT) genotypes (56.92% vs 38.86%; odds ratio, 2.08; 95% confidence interval, 1.21-3.56; P = .007) and T allele (33.08% vs 23.34%; odds ratio, 1.62; 95% confidence interval, 1.08-2.44; P = .019) were significantly more frequent in subjects who had MS. Furthermore, subjects with eNOS T+ genotypes had significantly higher plasma C-reactive protein levels as compared with GG subjects (P = .004). This study shows that, in a Chinese population, eNOS G894T polymorphism is associated with an elevated C-reactive protein level and MS.

Coronary artery disease (CAD) is a major cause of morbidity and mortality in patients with type 2 diabetes mellitus. When diabetes exists in patients with established CAD, absolute risk for future events is very high. Diabetic patients often have severe, yet asymptomatic, CAD. Although high-sensitivity C-reactive protein (hsCRP) is a strong independent risk factor for cardiovascular events, there is an unclear association between it and silent myocardial ischemia in diabetic patients. In this study, we assess the relationship between hsCRP and silent myocardial ischemia in Chinese with type 2 diabetes mellitus. We designed a cross-sectional study with 225 asymptomatic diabetic patients having no known CAD. Ischemia was assessed by myocardial perfusion imaging. A total of 109 patients (48.4%) was found to have silent myocardial ischemia. Logistic regression analysis revealed age (odds ratio = 4.01, P = .002) (95% confidence interval, 1.98-7.44) and hsCRP (odds ratio = 2.58, P = .005) (95% confidence interval, 1.33-5.01) to be associated with greater risk of silent myocardial ischemia. Using the American Diabetes Association screening guidelines to evaluate risk, we found silent myocardial ischemia to be equally distributed between diabetic patients with 2 or more cardiac risk factors and those with less than 2 risk factors. Twenty-seven (24.8%) patients with silent myocardial ischemia were missed when the American Diabetes Association guidelines were used alone. High-sensitivity C-reactive protein was associated with silent myocardial ischemia in our study. High-sensitivity C-reactive protein might help detect silent myocardial ischemia in diabetic Chinese who may need aggressive treatment to reduce future CAD morbidity and mortality in Taiwan.

OBJECTIVE: In 2003, the American Diabetes Association recommended that the lower limit for the diagnosis of impaired fasting glucose (IFG) should be reduced from 110 to 100 mg/dL in the analysis of the associated risk factors of IFG. It has been proposed that liver dysfunction may contribute to the development of type 2 diabetes. A primary aim was to investigate the relationship between liver enzyme and insulin resistance (IR) in IFG group. The secondary aim was to investigate IR and beta-cell function assessed by homeostasis model assessment (HOMA-IR and HOMA-%B, respectively) in subjects with fasting plasma glucose (FPG) between 100 and 109 mg/dL. METHODS: We enrolled 284 subjects whose medical history and physical examination required tests to screen for metabolic abnormalities. In addition, we also excluded all factors affecting glucose or insulin metabolism. According to the FPG level, they were divided into the following groups: group A, FPG < 100 mg/dL; group B, FPG = 100 to 109 mg/dL; group C, FPG = 110 to 125 mg/dL. RESULTS: Group B as compared with group A had significant increase of HOMA-IR and decrease of HOMA-%B. Among the whole population, the fasting insulin level, the fasting glucose, HbA1c, HOMA-IR, alanine aminotransferase, gamma-glutamyltranspeptidase, aspartate aminotransferase, and the diastolic blood pressure all increased significantly as the glycemic status progressed, whereas HOMA-%B levels decreased significantly as the glycemic status progressed. The lipid profile, alkaline phosphatase, and systolic blood pressure did not differ significantly among 3 different glycemic classifications. CONCLUSIONS: Study results indicate that, first, there was a significant decrease of insulin sensitivity and insulin secretion in subjects with fasting glucose from 100 to 109 mg/dL compared with subjects with normal fasting glucose. Second, alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyltranspeptidase were associated with IR as the glycemic status progressed in the IFG group.
