Clinical Characteristics, Glycemic Control, and Microvascular Complications Compared Between Young-Onset Type 1 and Type 2 Diabetes Patients at Siriraj Hospital - A Tertiary Referral Center.

Purpose: This study aimed to investigate the clinical characteristics, glycemic control, and microvascular complications compared between young-onset type 1 (T1DM) and type 2 diabetes (T2DM) patients at Siriraj Hospital. Patients and Methods: We collected demographic, clinical, glycemic control, and microvascular complication data of young-onset (onset <30 years of age) T1DM and T2DM patients at our center using February 2019-December 2020 data from the Thai Type 1 Diabetes and Diabetes diagnosed Age before 30 years Registry, Care and Network (T1DDAR CN). Results: Of 396 patients, 76% had T1DM and 24% had T2DM. At diagnosis, T1DM were significantly younger (9.7±5.4 vs 16.9±6.4 years, p<0.001), had a lower body mass index (17.2±4.1 vs 30.8±7.9 kg/m2, p<0.001), higher prevalence of diabetic ketoacidosis (DKA) (66.1% vs 13.7%, p<0.001), and higher HbA1c level (12.8±2.6% vs 10.9±3.1%, p=0.002) compared to T2DM. Regarding glycemic control, the mean HbA1c at registry enrollment did not differ between groups (T1DM 8.3±1.8% vs T2DM 8.1±2.2%, p=0.303), but T1DM achieved HbA1c <7% significantly less than T2DM (19.3% vs 47.8%, p<0.001). T1DM showed deterioration of glycemic control during 10-20 years of age, and gradually improved during 20-30 years of age, whereas patients with T2DM showed progressive worsening of glycemic control over time. Concerning microvascular complications, the prevalence of diabetic retinopathy (10.6% vs 9%, p=0.92) and diabetic neuropathy (3.4% vs 5.5%, p=0.514) between T1DM and T2DM was not significantly different. However, T2DM had a significantly higher prevalence of diabetic nephropathy (T1DM 10.1% vs T2DM 40.2%, p<0.001) that developed within a significantly shorter duration of diabetes (T1DM 11.0±6.8 vs T2DM 4.3±5.1 years, p<0.001) compared to T1DM. Conclusion: T1DM had a significantly high prevalence of DKA at presentation, and most T1DM did not achieve the glycemic target, especially during adolescence. T2DM had a significantly higher prevalence of diabetic nephropathy that developed within a shorter duration of diabetes compared to T1DM.

Young-onset diabetes patients in Thailand: Data from Thai Type 1 Diabetes and Diabetes diagnosed Age before 30 years Registry, Care and Network (T1DDAR CN).

AIMS/INTRODUCTION: There is a lack of current information regarding young-onset diabetes in Thailand. Thus, the objectives of this study were to describe the types of diabetes, the clinical characteristics, the treatment regimens and achievement of glycemic control in Thai patients with young-onset diabetes. MATERIALS AND METHODS: Data of 2,844 patients with diabetes onset before 30 years-of-age were retrospectively reviewed from a diabetes registry comprising 31 hospitals in Thailand. Gestational diabetes was excluded. RESULTS: Based on clinical criteria, type 1 diabetes was identified in 62.6% of patients, type 2 diabetes in 30.7%, neonatal diabetes in 0.8%, other monogenic diabetes in 1.7%, secondary diabetes in 3.0%, genetic syndromes associated with diabetes in 0.9% and other types of diabetes in 0.4%. Type 1 diabetes accounted for 72.3% of patients with age of onset <20 years. The proportion of type 2 diabetes was 61.0% of patients with age of onset from 20 to <30 years. Intensive insulin treatment was prescribed to 55.2% of type 1 diabetes patients. Oral antidiabetic agent alone was used in 50.8% of type 2 diabetes patients, whereas 44.1% received insulin treatment. Most monogenic diabetes, secondary diabetes and genetic syndromes associated with diabetes required insulin treatment. Achievement of glycemic control was identified in 12.4% of type 1 diabetes patients, 30% of type 2 diabetes patients, 36.4% of neonatal diabetes patients, 28.3% of other monogenic diabetes patients, 45.6% of secondary diabetes patients and 28% of genetic syndromes associated with diabetes patients. CONCLUSION: In this registry, type 1 diabetes remains the most common type and the prevalence of type 2 diabetes increases with age. The majority of patients did not achieve the glycemic target, especially type 1 diabetes patients.

Type 1 diabetes management and outcomes: A multicenter study in Thailand.

AIMS/INTRODUCTION: The Thai Type 1 Diabetes and Diabetes Diagnosed Before Age 30 Years Registry, Care and Network was established in 2014 and involved 31 hospitals. The objective of the registry was to evaluate glycemic control and complications of patients with type 1 diabetes. MATERIALS AND METHODS: Patients' demographics, clinical data, frequencies of daily self-monitoring of blood glucose (SMBG), glycemic control and complications were collected. RESULTS: Among the 1,907 type 1 diabetes patients, the mean age was 21.2 ± 11.3 years. The mean glycated hemoglobin level was 9.35 ± 2.41%, with significant variations among age groups (P < 0.001). Conventional insulin treatment and intensive insulin treatment were used in 43 and 57% of patients, respectively. Mean glycated hemoglobin levels were significantly higher in patients treated with conventional insulin treatment compared to those treated with intensive insulin treatment (9.63 ± 2.34 vs 9.17 ± 2.46%, P = 0.002). Compared to the conventional insulin treatment group, significantly more patients in the intensive insulin treatment group achieved good glycemic control (P < 0.001), and fewer had diabetic retinopathy (P = 0.031). The prevalence of microvascular complications increased significantly with age (P < 0.001). Multivariate analysis showed good glycemic control to be associated with age 25 to <45 years, intensive insulin treatment with SMBG three or more times daily and diabetes duration of 1 to <5 years. CONCLUSIONS: Most Thai type 1 diabetes patients were not meeting the recommended glycemic target. As a result of this study, the national program to improve the quality of diabetes treatment and education has been implemented, and the results are ongoing.

Real-world Evaluation of glycemic control and hypoglycemic Events among type 2 Diabetes mellitus study (REEDS): a multicentre, cross-sectional study in Thailand.

OBJECTIVE: Patients with type 2 diabetes mellitus (T2DM) often experience hypoglycaemia and weight gain due to treatment side effects. Sulfonylureas (SU) and the combination of SU and metformin (SU+MET) were the most common monotherapy and combination therapies used in Thailand tertiary care hospitals. This study aimed to assess the glycaemic goal attainment rates, hypoglycaemic episodes, weight gain and treatment compliance among patients with T2DM receiving SU or SU+MET. RESEARCH DESIGN AND METHODS: A multicentre cross-sectional survey and retrospective review was conducted in five tertiary care hospitals, Thailand. Patients with T2DM aged ≥30 years were included consecutively during a 12-month period. Glycaemic control, experiences of hypoglycaemia, weight gain and compliance were evaluated. Glycaemic goal attainment was defined by HbA1c level less than 7%. RESULTS: Out of the 659 patients (mean age (±SD)), 65.5 (10.0) years and median duration of T2DM (IQR), 10 (5-15) years), 313 (47.5%) achieved the glycaemic goal. HbA1c levels in the patients with goal attainment was significantly lower compared with those without (6.3%±0.5% vs 8.1%±1.2%, p<0.001). Goal attainment was significantly lower among patients treated with SU+MET than those treated with SU alone (43.5% vs 63.0%; OR 0.45, 95% CI 0.31, 0.66, p<0.001). A third of patients reported experiencing hypoglycaemia (30.7%) and weight gain (35.4%). Weight gain in the SU+MET group was lower than those receiving SU alone (33.1% vs 44.6%, p=0.015), but there was no difference in hypoglycaemic events. Major events in the previous 12 months were experienced by 68 patients, most commonly congestive heart failure and ischaemic heart disease. Approximately half of the patients (52.2%) reported not always taking their medication as prescribed. CONCLUSIONS: Among patients with T2DM receiving SU or SU+MET, only about half of the patients achieved glycaemic goal and compliance with the treatment. Hypoglycaemia and weight gain posed a significant burden with risk of weight gain higher in the SU group.

Impact of Hypoglycemia on Health-Related Quality of Life among Type 2 Diabetes: A Cross-Sectional Study in Thailand.

Type 2 diabetes mellitus (T2DM) is one of the most common chronic diseases. Patients are generally advised lifestyle changes with antihyperglycemic agents prescribed. The major drawback of prescribing antihyperglycemic agents is the risk of hypoglycemia which subsequently impacts on health-related quality of life (HRQoL). This study is aimed at examining association between previous history of hypoglycemia and HRQoL. The study was a multicenter cross-sectional study, conducted from February 2013 to March 2015 at 5 tertiary care hospitals in Thailand (Srinagarind, Phramongkutklao, Ramathibodi, King Chulalongkorn Memorial, and Siriraj hospitals). The study population were males or females diagnosed with type 2 DM according to ADA criteria, 30 years of age or older, who had been treated with sulfonylurea (SU) monotherapy or SU and metformin combination for at least 6 months. Prespecified medical factors were extracted from medical records 12 months prior to patients' enrolment. The experience of hypoglycemia questionnaire was used to collect and measure severity of hypoglycemia experienced during the previous 6 months. HRQoL was assessed using the 3-level version of EuroQol-5-dimension (EQ-5D-3L) and visual analogue scale (EQ-VAS) questionnaires. Of 659 eligible patients surveyed, 202 patients (30.65%) had experienced symptoms of hypoglycemia. HRQoL was significantly lower among patients reporting at least one of hypoglycemic symptoms, measured by EQ-VAS scores (mean ± SD; 73.66 ± 13.18, 73.56 ± 15.10, or 68.93 ± 14.76 vs. 77.01 ± 13.02, one-way ANOVA; p = 0.006) and EQ-5D-3L index scores (0.62 ± 0.47, 0.68 ± 0.38, or 0.58 ± 0.51 vs. 0.79 ± 0.31, one-way ANOVA; p < 0.001) for mild, moderate, or severe/very severe hypoglycemic patients compared with patients without hypoglycemic symptoms. After adjusting for confounding factors in a multiple linear regression model, patients with hypoglycemic symptoms either mild, moderate, or severe/very severe demonstrated significantly higher impairment for EQ-VAS and EQ-5D indexes than those who did not experience hypoglycemic symptoms. In conclusion, our study showed decreased HRQoL determined by EQ-5D and EQ-VAS in patients reporting symptoms of hypoglycemia compared with patients not reporting hypoglycemic symptoms, relative to severity of hypoglycemia.

The Berlin Declaration: Inspiration for primary care.

This paper describes the seminal Berlin Declaration, released in December 2016, and draws inspiration from it to ensure early prevention, early detection, and early control of diabetes, and provide early access to the right interventions for diabetes care. Discussion focuses on actions which primary care physicians can take in their individual practices to help achieve the goals laid down in Berlin Declaration. Collective efforts, involving simple, achievable and measurable interventions, will facilitate fulfillment of the Berlin Declaration's aims and objectives.

Efficacy of low- and moderate-intensity statins for achieving low- density lipoprotein cholesterol targets in Thai type 2 diabetic patients.

BACKGROUND: Low dose statins are commonly used among Asians, because plasma low-density lipoprotein cholesterol (LDL-C) reductions similar to those observed in Westerners are achieved at lower doses. We aimed to assess the efficacy of low- and moderate-intensity statins for achieving plasma lipid targets in Thai type2 diabetes (T2D) and to evaluate factors associated with greater LDL-C reduction by statins. METHODS: T2D patients who were treated with low- and moderate-intensity statins at the Siriraj Diabetes Clinic during the January 2013 to December 2014 study period were eligible for inclusion(n = 978), 400 patients were randomly recruited. Patients were classified into 1 of the following 2 groups according to their plasma LDL-C reductions by statins (N = 393); very favorable response (LDL-C reduction ≥50%) or less favorable response (LDL-C reduction <50%). RESULTS: Of the 400 patients, 41.3% were low-intensity statin users. Mean age was 64.4 ± 12.7 years, 64% were female. Median duration of diabetes was 13.3 years and mean HbA1C was 8.1 ± 1.9%. Plasma LDL-C goal of <100 mg/dl and <70 mg/dl was achieved in 84.3% and 38.0% respectively, with no significant difference between the low- and moderate-intensity statin users. LDL-C reductions ≥50% can be achieved in 38.4%. Factors associated with very favorable responses from statins were age, hypertension, patients with stable or reduced weight, and better glycemic control. CONCLUSION: Low- and moderate-intensity statins achieved plasma LDL-C goal of <100 mg/dl and <70 mg/dl in 84.3%, and 38.4% of the patients respectively. Due to the improved response to lower doses observed in Asians, a titration dosage strategy should be considered.

Glycemic control, quality of life and self-care behavior among adolescents with type 1 diabetes who attended a diabetes camp.

A prospective study was conducted at the tenth Siriraj diabetes camp with the objectives of evaluating the effectiveness of diabetes camp on 1) glycemic control, 2) knowledge, 3) quality of life, and 4) self-care behavior of adolescents with type 1 diabetes (T1D) who participated in the diabetes camp. During the 5-day camp, twenty-seven participants (mean age 15.6 +/- 2.1 years, mean duration 6.3 +/- 3.0 years) were taught diabetes self-management education (DSME) and engaged in psychosocial support sessions. Post-camp activities were held every 3 months and participants were followed for 12 months post-camp. Glycemic control was assessed prior to the camp, then every 3 months. Knowledge level was assessed prior to the camp, at the end of the camp, and every 3 months. Diabetes self-care behavior and quality of life were evaluated prior to the camp, at 3 months and 12 months after the camp. After attending the camp, participants had improvement in knowledge but there were no changes in HbA1c levels or quality of life scores. Quality of life was not consistently associated with HbA1c. In general, participants did not perceive their quality of life was poor or feel having diabetes affected their social life. The issue participants worried about most was whether they would develop complications from diabetes. There were several weak points found among participant self-care behavior, particularly in diet-related matters. Despite no improvement in glycemic control, participants gained knowledge from attending the camp. Diet related self-care behavior is difficult for teenagers with T1D to be compliant.

Hypoglycemia is associated with increased worry and lower quality of life among patients with type 2 diabetes treated with oral antihyperglycemic agents in the Asia-Pacific region.

AIMS: We examined the relationship of hypoglycemic symptoms with health-related quality of life and worry about hypoglycemia among type 2 diabetic patients using oral antihyperglycemic agents (AHA) in the Asia-Pacific region. METHODS: A total of 2257 type 2 diabetic patients with at least 6 months of oral AHA were enrolled in China, Korea, Malaysia, Thailand, and Taiwan. Quality of life was measured with the EuroQol Visual Analog Scale (EQ-VAS) and EuroQol-5 Dimensions questionnaire (EQ-5D), and worry about hypoglycemia with the worry subscale of the Hypoglycemic Fear Survey-II (HFS). RESULTS: The mean (SD) age was 58.7 (10.2) years and HbA(1c) was 7.5% (1.5). The proportion of patients with an HbA(1c) <6.5% and <7% was 24.9% and 41.8%, respectively. Hypoglycemic symptoms in the prior 6 months were reported by 35.8% of patients. Mean scores on the EQ-VAS and the EQ-5D were significantly lower for patients who had hypoglycemic symptoms compared to those who did not (73.6 vs. 76.9, p<0.001; 0.88 vs. 0.90, p<0.0001, respectively), whereas mean score on the HFS was significantly higher (12.5 vs. 6.3, p<0.001). In multivariate models, hypoglycemic symptoms were independently associated with scores on the EQ-5D, EQ-VAS, and HFS (all p ≤ 0.01-0.001). Symptom severity was positively associated with fear of hypoglycemia (all p ≤ 0.001). CONCLUSION: Hypoglycemic symptoms were associated with reduced quality of life and increased patient worry in patients with type 2 diabetes treated with AHA.

Urban and rural variation in clustering of metabolic syndrome components in the Thai population: results from the fourth National Health Examination Survey 2009.

BACKGROUND: Information on the distribution of Metabolic syndrome (MetS) and its combinations by urban/rural areas in lower-middle income countries has been limited. It is not clear how the various combinations of MetS components varied by urban/rural population and if particular combinations of MetS are more common. This study aimed to estimate the prevalence of MetS and combinations of MetS components according to sex and urban/rural areas from a nationally representative sample of Thai adults. METHODS: Data from the fourth National Health Examination Survey of 19,256 Thai adults aged 20 years and over were analyzed. MetS was defined using the harmonized criteria of six international expert groups with Asian-specific cut-point for waist circumference. RESULTS: The prevalence of MetS was 23.2% among adults aged ≥ 20 years (19.5% in men and 26.8% in women). Among men, the prevalence of MetS in urban was higher than those in rural areas (23.1% vs 17.9%, P < 0.05), but among women, the prevalence was higher in rural areas (27.9% vs 24.5%, P < 0.05). Overall, an individual component of low high density lipoprotein (HDL) and hypertriglyceridemia were more common in rural areas, while obesity, high blood pressure and hyperglycemia were more common in urban areas. The most common combination of MetS components in men was the clustering of low HDL, hypertriglyceridemia, and high blood pressure (urban: 3.4% vs. rural: 3.9%, adjusted OR 0.9, 95%CI 0.7, 1.1). Among women, the most common combination was the clustering of obesity, low HDL, and hypertriglyceridemia (urban: 3.9% vs rural: 5.9%, adjusted OR 0.8, 95%CI 0.6, 0.9), followed by the clustering of these three components with high blood pressure (urban: 3.1% vs. rural 4.5%, adjusted OR 0.8, 95%CI 0.7, 0.9). CONCLUSION: Metabolic syndrome affects both urban and rural population with different pattern of MetS combinations. Dyslipidemia and obesity were the most common components among women in rural areas, hence, interventions to prevent and control these factors should be strengthened.

Blood glucose patterns in type 2 diabetic patients with optimal fasting plasma glucose but high HbA1c.

BACKGROUND: Achieving fasting plasma glucose (FPG) target may not reflect hemoglobin A1c (HbA1c) target achievement. OBJECTIVE: Illustrate the blood glucose patterns contributing to HbA1c > 7% in patients whose FPG was < 130 mg/dl and correlation between HbA1c and plasma glucose at various times. The contribution of caloric intake, carbohydrate consumption and glycemic index of food to plasma glucose were determined. MATERIAL AND METHOD: Patients with type 2 diabetes, attended out-patient clinics at Siriraj Hospital, who had FPG of < 130 mg/dl but HbA1c level of > 7% were invited to participate in this 4-week study. They were treated with single or combined oral hypoglycemic agents except for alpha glucosidase inhibitors and glinide. Each patient performed self monitoring of capillary plasma glucose (CPG) before and 2 hours after each meal and before retiring to bed on the most convenient day in the first and fourth weeks and monitored two CPG before breakfast and before dinner weekly. Daily food intake was recorded in the logbooks. RESULTS: The observed patterns of CPG in 60 cases were postprandial hyperglycemia with FPG of < 130 mg/dl in 21.7%, a high pre-meal and post-meal CPG with FPG of < 130 mg/dl in 36.7% and elevated all fasting, pre-meal and post-meal CPG in 41.7% of the patients. The correlation coefficients between HbA1c at the end of the present study and CPG were 0.345, 0.40 and 0.337 at pre-breakfast, pre-lunch and pre-dinner, respectively (p = 0.01). The correlation coefficients between HbA1c and 2 hours CPG post-lunch, post-dinner and bed time were 0.402, 0.412 and 0.472, respectively (p = 0.01). The correlation between CPG and caloric intake, carbohydrate consumption or glycemic index of food were not observed. CONCLUSION: Elevated blood glucose at all times was the commonest finding in type 2 diabetic patients whose FPG < 130 mg/ dl but HbA1c level > 7%. A sole measurement of FPG should not be used to assure optimal glycemic control. Significant correlations between HbA1c and pre- or post- meal CPG indicated that frequent monitoring of pre- and post- meal could be used in assessing overall glycemic control.

Hypoglycemic symptoms in patients with type 2 diabetes in Asia-Pacific-Real-life effectiveness and care patterns of diabetes management: the RECAP-DM study.

Symptoms of hypoglycemia were reported by 35.8% of patients with type 2 diabetes treated with oral antihyperglycemic agents in the Asia-Pacific region. Symptoms were severe in 11.6% and very severe in 8.2% of patients experiencing hypoglycemia.

Non-Hodgkin lymphoma with adrenal insufficiency: a case report and literature review.

A 62-year-old Thai man was admitted because of nausea and vomiting with incidentally detected bilateral adrenal enlargement. The basal cortisol was low and ACTH level was elevated CT guided percutaneous needle biopsy of adrenal gland showed a diffuse infiltration of medium to large atypical lymphoid cells of B-cell immunophenotype, which are diagnostic for a diffuse large B-cell lymphoma. Involvement by large B-cell lymphoma was documented in bone marrow biopsy as well. The findings confirmed the diagnosis of primary adrenal insufficiency caused by large B-cell lymphoma involving both adrenal glands.

Lipid treatment assessment project II in Thailand (LTAP-II Thailand).

OBJECTIVE: Evaluate treatment practices and their outcomes in Thai patients with hyperlipidemia. The factors contributing to success of treatment were also determined. MATERIAL AND METHOD: A multi-center cross-sectional survey with the support of 98 physicians from 48 hospitals was done. Each physician enrolled up to 20 dyslipidemic patients by simple randomization. RESULTS: One thousand nine hundred twenty one cases, 45.1% males with a mean age of 58.6 years (SD = 9.6) were recruited. The patients were divided into three groups: 1,178 patients with coronary heart disease (CHD) and CHD equivalents, 424 patients with high risk, and 319 patients with low risk. The main targets for treatment were LDL-C levels of< 100, < 130 and < 160 mg/dL for each respective group. As a whole, the risk factors listed in order of frequency were age at risk (78%), hypertension (69. 8%), diabetes mellitus (43.6%), smoking (24.6%), and family history of CHD (6.9%). Obesity (body mass index > or = 25 kg/m2) was found in 53.8% of the patients. Twenty eight percent of the patients experienced CHD or other atherosclerotic diseases. Statin was the commonest prescribed drug (64%) followed by fibrate (25%). The overall success rate was 46.5%. Percentage of cases achieving LDL-C targets in the CHD and CHD equivalents, high and low risk group was 34.6%, 56.4%, and 76.8%, respectively. The patients in the low risk group, being under specialist care and receiving statin therapy reached target of treatment at a significantly higher rate. CONCLUSION: The present study showed that statin was the most common drug used in the management of hyperlipidemia. Patients with CHD and CHD equivalents were the group with least achievement of LDL-C target. The factors contributing to achievement of LDL-C target were lower risk patient, specialist care, and statin therapy.

Glycemic control and the psychosocial benefits gained by patients with type 1 diabetes mellitus attending the diabetes camp.

OBJECTIVE: The aim of this study was to evaluate the effectiveness of diabetes camp on glycemic control, knowledge, and psychosocial benefits among patients with type 1 diabetes (T1D). Glycemic control among patients with infrequent and frequent self-monitoring of blood glucose (SMBG) was also compared. METHODS: During a 5-day camp, 60 patients were taught diabetes self-management education (DSME). After camp, patients were divided into two groups based on frequency of SMBG (<3 versus 3-4 times/day) and were followed up until 6-month post-camp. Patients' HbA1c levels and knowledge were assessed at baseline, 3- and 6-month post-camp. Patients' impressions towards camp were assessed. RESULTS: In both SMBG groups, HbA1c levels decreased significantly at 3-month post-camp but did not sustain at 6-month monitoring. The patients with frequent SMBG had a lower mean HbA1c level. A significant improvement in knowledge was noted and sustained up to 6-month post-camp. The patients found diabetes camp of benefit and felt they could better cope with diabetes. CONCLUSIONS: Although the effect of the diabetes camp on glycemic control was short-lived, an improvement in knowledge and a better attitude towards having diabetes were seen among participants. PRACTICE IMPLICATIONS: The psychosocial benefits and knowledge gained by patients attending diabetes camp underline the importance of including a camp in a diabetes management plan. To improve patients' long-term glycemic control, a continuous education is required.

Glycemic and lipid responses to glucomannan in Thais with type 2 diabetes mellitus.

OBJECTIVE: To evaluate the benefits of glucomannan supplement on glycemic and lipid controls in type 2 diabetic patients. MATERIAL AND METHOD: A single-blind, placebo-controlled, crossover trial with two treatments separated by a 2-week washout period was performed in 10 men and 10 women with type 2 diabetes mellitus. Two separated protocols of experiments were sequentially followed. Initially, purified glucomannan (1 g) or placebo was ingested 30 min before 75-g glucose load to evaluate their effects on glucose absorption and insulin secretion in oral glucose tolerance test (OGTT). Later, the glycemic and lipid changes after 4-week intervention with 3 g/day glucomannan comparing to the placebo were determined. The standard OGTT was performed before and after ending of each intervention. RESULTS: Glucomannan taken before performing the OGTT can lower the rise of blood glucose and insulin from 1 to 2 hour in comparison with the placebo, though a statistically significance of insulin was not achieved. Long-term glucomannan supplement significantly reduced the 120-min glucose area under the curve of OGTT. Glucomannan also decreased the rise of low-density lipoprotein cholesterol (LDL-C). Reductions of HOMA-insulin resistance index and body mass index were detected in glucomannan-treated group though the former was shown only in females. No within- and between-group differences of insulin, fructosamine, and other lipids were observed in glucomannan- nor placebo- treated groups. CONCLUSION: In type 2 diabetes, pre-prandial glucomannan ingestion attenuated a rise of blood glucose without significantly affecting insulin levels. Long-term supplement of glucomannan to the regular diabetic regimen lessened post challenge glucose AUC and impeded the rise of LDL-C. Supplement of glucomannan may be beneficial to the glycemic and lipid controls in type 2 diabetes mellitus.

A survey study on diabetes management and complication status in primary care setting in Thailand.

OBJECTIVE: Healthcare service in Thailand is stratified into three levels with different facilities of care. This cross-sectional survey study described diabetes management, diabetes control, and late complication status among patients managed in urban primary health care clinics. MATERIAL AND METHOD: Thirty-seven primary health care units were randomly selected. Each unit enrolled up to 30 patients having been managed in the unit for at least one year. The patients were interviewed, and the medical records such as demographic data, management practice, glycemic control, and complications were retrospectively reviewed for a period of one year. All data were entered in the case record forms, transferred into a database by electronic scanning, and analyzed by SAS version 6.12. One thousand and seventy-eight patients, including 300 males and 778 females, were recruited in the present study. RESULT: Their mean +/- SD of age, onset age, and diabetes duration were 58.2 +/- 11.3, 52.2 +/- 11.4 and 6.2 +/- 4.0 years, respectively. Six percent of the patients were type 1, and 94% were type 2 diabetes. Two-thirds of the patients engaged in diabetes education > or = 5 days during the previous year. Monitoring of glycemic control was largely by measurement of fasting plasma glucose (FPG) in the unit. Determination of hemoglobin A1c (HbA1c), total cholesterol, triglyceride, HDL-cholesterol, serum creatinine, urinary protein, and microalbuminuria were observed in 0.7, 17.4, 11.7, 6.9, 38.2, 33.0, and 0.9% of the patients, respectively. Mean +/- SD of FPG was 8.3 +/- 2.7 mmol/l, and HbA1c was 8.6 +/- 1.9%. The percentage of patients with FPG < 6.7 mmol/l and HbA1c < 7% were 28.7 and 19.6%, respectively. An annual eye and foot examination was performed in 21.5% and 45% of the patients, respectively. The prevalence of late complications included retinopathy (13.6%), proteinuria (17.0%), end stage renal failure (0.1%), peripheral neuropathy (34%), acute foot ulcer/gangrene (1.2%), healed foot ulcer (6.9%), stroke (1.9%), and myocardial infarction (0.7%). CONCLUSION: The present study results demonstrated that necessary, routine assessments were not regularly practiced by caregivers in primary care units. In addition, peripheral neuropathy was the most common observed complication and this might explain the high rate of foot ulcers in this cohort.

The Atorvastatin Goal Achievement Across Risk Levels: (ATGOAL) study in Thailand.

OBJECTIVE: To evaluate the efficacy and safety of atorvastatin at the starting doses of 10, 20, 40 mg and evaluate the effectiveness of 1 step titrate up regimen. MATERIAL AND METHOD: Two hundred and forty two subjects with dyslipidemia were enrolled and assigned the appropriate dose in relation to their individual cardiovascular risk status and baseline LDL-C levels. If the NCEP targets were not achieved, the doses were titrated up at week 4 and the primary efficacy was evaluated at week 8. RESULTS: A majority of subjects (88.8%) achieved their LDL-C goals at week 8. Almost all of the subject's LDL-C levels reached their goals by week 2 and 4 (81.6% and 87.1%, respectively). Only 10.7% (n = 25) required the sole titration. Each dose provided significant decreases in LDL-C (average -46.4%). Only 36 subjects experienced treatment related adverse events, the majority of these were in the high-risk group (n = 22) with only one subject registering a serious adverse event. CONCLUSION: Atorvastatin is effective and safe for Thai patients with dyslipidemia. The appropriate starting dose has contributed in the achievement of cholesterol reduction.

Metabolic syndrome: recent prevalence in East and Southeast Asian populations.

BACKGROUND: The prevalence of the metabolic syndrome among a number of Asian populations as defined by several current criteria has been increasing rapidly and appears to resemble that among Western populations. METHODS: We review 25 surveys of the metabolic syndrome in Asian populations (PR China, Hong Kong, Taiwan, Japan, Philippines, Singapore) that report adequate information published during the last 5 years. RESULTS: Using Asian-adapted definitions of obesity (BMI > or = 25 kg/m(2)) and increased waist circumference (for male > or = 90 cm; for female > or =80 cm) prevalence appears to be between 10 to 30%. Those with the syndrome are more likely to have a history of diabetes and cardiovascular disease. The risk of developing Type 2 diabetes is 10 times higher among middle-aged Japanese men with the metabolic syndrome compared to healthy subjects. In Chinese and Japanese populations, people who have the metabolic syndrome are 3 to 10 times more likely to develop cardiovascular disease. Variance in prevalence estimates of the metabolic syndrome even within the same country result from differences in sampling and possibly from definitions. CONCLUSIONS: The outstanding conclusion from recent surveys across the Asian-Pacific region is that of a consistent increase in the prevalence of the metabolic derangements associated with abdominal adiposity that lead to high risk of morbidity and mortality.
