Hospitalization in patients with type 2 diabetes mellitus in Taiwan: A nationwide population-based observational study.

BACKGROUND/PURPOSE: We investigated hospitalization rates of patients with type 2 diabetes mellitus (T2DM) and individuals without diabetes mellitus (non-DM) in a disease-specific manner from 2005 to 2014 in Taiwan. METHODS: This population-based study was conducted using data from the National Health Insurance Research Database. We analyzed the hospitalization rates of patients with and without T2DM. We collected up to five diagnostic codes given at discharge for each hospitalization, and the first one was considered the main diagnosis. Odds ratios were determined to assess the risk of hospitalization according to disease-specific classifications in patients with T2DM compared with those without T2DM. RESULTS: The hospitalization rates of non-DM patients was stable from 2005 to 2014. By contrast, the rate of hospitalization among patients with T2DM decreased from 395.4 (per 1000 person-years) in 2005 to 336.9 (per 1000 person-years) in 2014. An increase in hospitalization rates for malignancies and sepsis/infection (other than pneumonia) was observed from 2005 to 2014 in both patients with and without T2DM. Although patients with T2DM had a higher hospitalization risk for all the disease-specific classifications than non-DM patients, this difference in risk decreased from 2005 to 2014 for all diseases except pneumonia. CONCLUSION: Hospitalization rates for malignancies and sepsis/infection (other than pneumonia) continually increased from 2005 to 2014 in Taiwan. Although patients with T2DM had a greater risk of disease-specific hospitalization than those without, this difference in risk decreased from 2005 to 2014 for all diseases except for pneumonia.

The impact of ambient temperature on HbA1c in Taiwanese type 2 diabetic patients: The most vulnerable subgroup.

BACKGROUND/PURPOSE: The relationship between temperature variability and HbA1c has been reported in Caucasians, but not for Asians of Taiwanese origin. This study investigated the impact of temperature on HbA1c in various groups of Taiwanese with type 2 diabetes in Taiwan. METHODS: For this longitudinal follow-up study which started in 2006, we recruited a total of 4399 patients with type 2 diabetes who had been regularly followed up at Chi Mei Medical Center and obtained local temperature data for 2006 to 2011 from Taiwan's Central Weather Bureau. We used a generalized estimated equation (GEE) to analyze the HbA1c level and its change over time with temperature and temperature changes, respectively. RESULTS: We found a negative correlation between HbA1c and temperature (R = -0.475, p = 0.001). For every 1°C decrement in temperature, there was an increase in the risk of having a HbA1c level >7% [p < 0.001, adjusted odds ratio (OR): 1.01]. There was a significantly higher risk of HbA1c > 7% among those in the lowest quartile of temperatures than the highest quartile (p = 0.0038, adjusted OR: 1.13). Patients with diabetic patients were at higher risk of HbA1C > 7% in the winter and spring than those in the summer (adjusted OR: 1.13, p = 0.0027; adjusted OR: 1.14, p = 0.0022). After adjusting for various confounders, we found people who were younger than 65 years old, people who had diabetes for longer than 6 years, and people who had a body mass index (BMI) < 24 to be more susceptible to temperature changes (p = 0.0022, ß: 0.0095; p < 0.0001, ß: 0.0125; p < 0.0001, ß: 0.016, respectively). CONCLUSION: Our study suggests cold weather may adversely affect HbA1c levels in Taiwanese people with type 2 diabetes, especially in people under 65 years old, people with diabetes for longer than 6 years, and those with a BMI < 24.

Cytomorphological comparison of ThinPrep and SurePath liquid-based cytology in thyroid fine-needle aspiration.

BACKGROUND: The two widely established systems for liquid-based cytology (LBC), ThinPrep and SurePath, employ different principles. The aim of this study was to compare the cytomorphology of thyroid lesions prepared by the two techniques. METHODS: We retrospectively reviewed 44 thyroid FNA specimens prepared by LBC, including 20 ThinPrep and 22 SurePath. Cytologic diagnoses were made according to the Bethesda system and cytomorphologic parameters were evaluated. RESULTS: Acellular smears were significantly frequent in ThinPrep than SurePath (10% vs. 0%). Both techniques produced a clean background, well cell preservation, and not apparent cell shrinkage. ThinPrep showed significantly lower cellularity than SurePath (25% vs. 4.3%). ThinPrep produced considerable flattening and fragmented clusters, while SurePath contained larger clusters in a three-dimensional configuration. Colloid was significantly reduced in amount and fragmented in ThinPrep, and was easily observed in SurePath. In cases of Hashimoto's thyroiditis, ThinPrep produced much less leukocytes in background than SurePath. Aggregates of fibrin and leukocytes were frequently present in 10/16 cases (62.5%) processed by ThinPrep. Air-dry artifact at periphery of the ring was present in 6/16 cases (37.5%) processed by ThinPrep. The nuclear features of papillary carcinoma were similarly evident in both LBC preparations. CONCLUSION: SurePath seems to be superior to ThinPrep for diagnosing benign entities based on adequate representation of colloid and lymphocytes. The cell quality of both techniques in thyroid FNA was comparable, while each method introduces its own unique cytologic artifacts related to its methodology. We should recognize the cytomorphologic alterations to avoid misinterpretations.

Optimizing lipid control in Taiwanese diabetic patients: A collaborative consensus by the Diabetes Association of the Republic of China (Taiwan) and the Taiwanese Association of Diabetes Educators.

We present an in-depth analysis of dyslipidemia management strategies for patients with diabetes mellitus in Taiwan. It critically examines the disparity between established guideline recommendations and actual clinical practices, particularly in the context of evolving policies affecting statin prescriptions. The focus is on synthesizing the most recent findings concerning lipid management in patients with diabetes mellitus, with a special emphasis on establishing consensus regarding low-density lipoprotein cholesterol treatment targets. The article culminates in providing comprehensive, evidence-based recommendations tailored to the unique needs of those living with diabetes mellitus in Taiwan. It underscores the criticality of personalized care approaches, which incorporate multifaceted factors, and the integration of novel therapeutic options to enhance cardiovascular health outcomes.

A randomized trial on the effect of transcutaneous electrical nerve stimulator on glycemic control in patients with type 2 diabetes.

Transcutaneous electrical nerve stimulator (TENS) has been demonstrated to be beneficial in glycemic control in animal models, but its application in humans has not been well studied. We randomly assigned 160 patients with type 2 diabetes on oral antidiabetic drugs 1:1 to the TENS study device (n = 81) and placebo (n = 79). 147 (92%) randomized participants (mean [SD] age 59 [10] years, 92 men [58%], mean [SD] baseline HbA1c level 8.1% [0.6%]) completed the trial. At week 20, HbA1c decreased from 8.1% to 7.9% in the TENS group (- 0.2% [95% CI - 0.4% to - 0.1%]) and from 8.1% to 7.8% in the placebo group (- 0.3% [95% CI - 0.5% to - 0.2%]) (P = 0.821). Glycemic variability, measured as mean amplitude of glycemic excursion (MAGE) at week 20 were significantly different in the TENS group vs. the placebo group (66 mg/dL [95% CI 58, 73] vs. 79 mg/dL [95% CI 72, 87]) (P = 0.009). Our study provides the clinical evidence for the first time in humans that TENS does not demonstrate a statistically significant HbA1c reduction. However, it is a safe complementary therapy to improve MAGE in patients with type 2 diabetes.

Mortality and related risk factors in the co-presentation of tuberculosis and type 2 diabetes mellitus: a population-based study.

OBJECTIVE: Patients with type 2 diabetes mellitus (T2DM) are often immunosuppressed and susceptible to infectious diseases. We investigated the mortality and related risk factors of active TB disease in patients with T2DM in Taiwan. MATERIALS AND METHODS: The data of 1258 patients diagnosed with both T2DM and active TB disease from January 1 to December 31, 2002 (T2DM-TB group) were retrieved from the Taiwan National Health Insurance Research Database. Patients in the T2DM-TB group were matched by age, sex, and comorbidities to a control group of 10,064 T2DM patients without TB disease (T2DM group). Patients were followed up since TB diagnosis until death or 31 December 2011. Cox proportional-hazards regression analysis was employed to compare the risk of death between the T2DM group and the T2DM-TB group. RESULTS: A total of 101,837 potentially eligible patients were included in the study. After 1:10 propensity score matching, 1,258 patients were classified in the T2DM-TB group and 10,064 patients in the T2DM group. After adjustment for age, sex and comorbidities, the T2DM-TB group showed a 2.16-fold higher mortality risk than the T2DM group (95% CI = 1.83-2.56, p < .001). The mortality risk remained higher after stratification by year. The log-rank test indicated that male sex, age ≥60 years, hypertension and heart failure were independent risk factors. CONCLUSIONS: TB increases mortality risk in patients with T2DM on long-term follow-up. The independent risk factors for mortality in patients with concurrent T2DM and TB disease include male sex, age ≥60 years, hypertension and heart failure.KEY MESSAGESThe co-presentation of T2DM and TB is an important emerging issue, especially in Asia.This study showed mortality risk was significantly higher in the T2DM-TB group compared with the T2DM group on long-term follow-up.Increased medical attention is necessary for patients with T2DM and a history of TB disease.

A Randomized Controlled Trial of R-Form Verapamil Added to Ongoing Metformin Therapy in Patients with Type 2 Diabetes.

CONTEXT: There is a medical need for effective insulin-independent antidiabetic drugs that can promote pancreatic ß-cell function and have a low risk of hypoglycemia in type 2 diabetes mellitus (T2DM) patients. R-form verapamil (R-Vera), which is able to enhance the survival of ß-cells and has higher cardiovascular safety margin compared with racemic verapamil, was developed as a novel approach for T2DM treatment. OBJECTIVE: This randomized, double-blind, placebo-controlled clinical trial was designed to evaluate the efficacy and safety of 3 dosages of R-Vera added to ongoing metformin therapy in T2DM patients who had inadequate glycemic control on metformin alone. METHODS: Participants were randomly assigned in an equal ratio to receive R-Vera 450, 300, or 150 mg per day, or matching placebo, in combination with metformin. The primary endpoint was change in hemoglobin A1c (HbA1c) after 12 weeks of treatment. RESULTS: A total of 184 eligible participants were randomized to receive either R-Vera or placebo plus metformin. At week 12, significant reductions in HbA1c were observed for R-Vera 300 mg/day (-0.36, P = 0.0373) and 450 mg/day (-0.45, P = 0.0098) compared with placebo. The reduction in HbA1c correlated with decreasing fasting plasma glucose levels and improved HOMA2-ß score. Treatment with R-Vera was well tolerated with no hypoglycemic episodes occurring during the trial. CONCLUSION: Addition of R-Vera twice daily to ongoing metformin therapy significantly improved glycemic control in T2DM patients. The favorable efficacy and safety profile of R-Vera 300 mg/day can be considered as the appropriate dose for clinical practice.

Apolipoprotein E polymorphism and the progression of diabetic nephropathy in type 2 diabetes.

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.

The Impact of Antidiabetic Agents on Sarcopenia in Type 2 Diabetes: A Literature Review.

Sarcopenia is a geriatric syndrome characterized by decline of skeletal muscle mass and function. Contributing factors include nutritional, genetic, inflammatory, and endocrinal factors. The reported prevalence of sarcopenia in type 2 diabetes mellitus is high, especially in patients with poor glycemic control. Additionally, antidiabetic agents may alter the balance between protein synthesis and degradation through various mechanisms of skeletal muscle mass regulation. This study reviewed the literature on the pathogenesis of sarcopenia in diabetes mellitus and the current understanding of whether antidiabetic agents contribute positively or negatively to sarcopenia and muscle wasting.

Thyroid-stimulating hormone receptor antibodies during follow-up as remission markers in childhood-onset Graves' disease treated with antithyroid drugs.

Graves' disease is uncommon in children. The remission rate after antithyroid drugs (ATD) therapy is lower than in adults. We evaluated the clinical course of ATD therapy in children with Graves' disease in southern Taiwan to determine whether their biochemical markers could be used to predict remission in these patients. We retrospectively reviewed the clinical data of 53 children diagnosed with Graves' disease between 2009 and 2019. Clinical and biochemical parameters were analyzed for predictors of remission. About three-fourths of the patients were female. Their median age at diagnosis was 13 years. No sex differences were found in most clinical characteristics. There was no correlation between thyroid-stimulating hormone receptor antibody (TRAb) levels at diagnosis and thyroid function or adverse reactions to ATD. Relapse occurred in 62% of patients after discontinuation of first-course ATD therapy. Three variables-good initial response to ATD, a decrease in TRAb levels during the first year after diagnosis, and a decrease in TRAb levels during the second year after diagnosis-were significant predictors of remission for more than 18 months. In conclusion, children with Graves' disease who had early ATD-controlled Graves' disease and decreased TRAb levels during the first 2 years are likely to enter remission for more than 18 months.

Health-Related Quality of Life and Medical Resource Use in Patients with Osteoporosis and Depression: A Cross-Sectional Analysis from the National Health and Nutrition Examination Survey.

Background: Patients with either osteoporosis or depression are prone to develop other diseases and require more medical resources than do the general population. However, there are no studies on health-related quality of life (HRQoL) and medical resource use by osteoporosis patients with comorbid depression. We conducted this study for clarifying it. Methods: This cross-sectional study from 2005 to 2010 (6 years) analyzed 9776 National Health and Nutrition Examination Survey (NHANES) patients > 40 years old. Each patient was assigned to one of four groups: osteoporosis-positive(+) and depression-positive(+) (O+/D+); O+/D-; O-/D+; O-/D-. We used multivariate linear and logistic regression model to analyze the HRQoL and medical resource use between groups. Results: The O+/D+ group reported more unhealthy days of physical health, more unhealthy days of mental health, and more inactive days during a specified 30 days. The adjusted odds ratios (AORs) of O+/D+ patients who had poor general health (7.40, 95% CI = 4.80-11.40), who needed healthcare (3.25, 95% CI = 2.12-5.00), and who had been hospitalized overnight (2.71, 95% CI = 1.89-3.90) were significantly highest. Conclusions: Low HRQoL was significantly more prevalent in D+/O+ patients. We found that depression severity more significantly affected HRQoL than did osteoporosis. However, both diseases significantly increased the risk of high medical resource use.

Gender-dependent effect of ACE I/D and AGT M235T polymorphisms on the progression of urinary albumin excretion in Taiwanese with type 2 diabetes.

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.

Diabetic ketoacidosis further increases risk of Alzheimer's disease in patients with type 2 diabetes.

AIM: Diabetes mellitus (DM) is a known risk factor for dementia. It is unclear whether diabetic ketoacidosis (DKA) further increases the risk of dementia in patients with type 2 DM. METHODS: This retrospective nationwide population-based cohort study was conducted using Taiwan's National Health Insurance database. We extracted claims data for 4451 patients with type 2 diabetes and DKA and 8902 diabetic controls matched for age, gender, diabetes complication severity index, frequency of clinic visits and baseline comorbidities between 2000 and 2002. Patients with type 1 diabetes or prior hypoglycemia before index date were excluded. All patients were tracked until new dementia diagnosis, death, or end of 2011. RESULTS: Of the 4451 DKA patients, 211 (4.7%) and 305 (3.4%) of the 8902 diabetic controls were diagnosed as having dementia during the follow-up period. The incidence rate ratio (IRR) for dementia was 1.62 (95% CI 1.35-1.93; P < 0.0001) for patients with DKA versus diabetic patients without DKA. After adjusting for age, baseline comorbidities, geographic area, and income, patients with DKA were found to have 1.86 times the risk of developing dementia, compared to controls (95% CI 1.56-2.22, P < 0.0001). They were found to have a higher risk of Alzheimer's dementia (HR:1.86; 95% CI 1.52-2.28, P < 0.0001) but not non-Alzheimer's dementia. CONCLUSION: Type 2 diabetes patients with DKA are at increased risk of Alzheimer's dementia but not non-Alzheimer dementia.

Basal insulin therapy: Unmet medical needs in Asia and the new insulin glargine in diabetes treatment.

Diabetes remains a global epidemic and a tremendous health challenge, especially in the Asian population. Dramatic increases in the prevalence of diabetes across different countries or areas in Asia have been reported in recent epidemiological studies. Although clinical guidelines have strengthened appropriate antihyperglycemic medications and lifestyle modifications for optimal diabetes management, inadequate glycemic control still occurs in many patients with an increased risk of developing microvascular and macrovascular complications. Insulin administration is the main therapy for diabetes in response to the inability to secrete insulin, and is recommended in current guidelines to treat patients with type 2 diabetes after failure of oral antidiabetic drugs. Clinical studies have shown that long-acting insulin analogs improve basal glycemic control with reduced risk of hypoglycemia. In the present review, we discuss previous challenges with basal insulin therapy in Asia, the pharmacological development of insulin analogs to overcome the unmet medical needs and recent clinical studies of the new ultra-long-acting insulin analog, insulin glargine U300. Furthermore, relevant findings of current real-world evidence are also included for the comparison of the efficacy and safety of different insulin formulations. Based on the accumulating evidence showing a low incidence of hypoglycemia and technical benefits of dose titration, treatment with glargine U300 can be a promising strategy for Asian diabetes patients to achieve glycemic targets with favorable safety.

Chronic kidney disease as a risk factor for coronary artery disease in Chinese with type 2 diabetes.

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.

Exon 33 T/T genotype of the thyroglobulin gene is a susceptibility gene for Graves' disease in Taiwanese and exon 12 C/C genotype protects against it.

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 C/T polymorphism in CD40 gene is not associated with susceptibility and phenotype of Graves' disease in Taiwanese.

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.

Association between a C/T polymorphism in exon 33 of the thyroglobulin gene is associated with relapse of Graves' hyperthyroidism after antithyroid withdrawal in Taiwanese.

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.

Cholesteryl ester transfer protein B1B1 genotype as a predictor of coronary artery disease in Taiwanese with type 2 diabetes mellitus.

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.

Acute suppurative thyroiditis with deep neck infection: a case report.

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.
