Role of metformin in the initiation of pharmacotherapy for type 2 diabetes: an Asian-Pacific perspective.

Increases in the prevalence of type 2 diabetes of 30-60% will occur in many Asian-Pacific countries by 2025, driven by urbanisation, sedentary habits and energy-rich diets. Obesity, insulin resistance, metabolic syndrome and diabetes are closely interrelated. Optimal control of diabetes and associated risk factors has reduced the risk of diabetes-related complications. In the UK Prospective Diabetes Study (UKPDS), metformin reduced the risk of macrovascular complications and retrospective analyses have confirmed the efficacy of metformin in improving clinical outcomes in type 2 diabetic patients with a history of cardiovascular disease. This growing body of evidence has led to the recommendation of metformin as optimum initial pharmacotherapy in overweight type 2 diabetic patients. Obesity is less prevalent in the Asian-Pacific population than in Caucasian populations. Nevertheless, metformin has multiple beneficial metabolic effects, which provide sufficient rationale for it to be recommended as the initial oral anti-diabetic pharmacotherapy, alone or in combination, irrespective of body mass index. This recommendation is consistent with global guidelines and regional recommendations for the Asian-Pacific region from the International Diabetes Federation. These recommendations can serve as templates for development of local guidelines for Asian people with diabetes, given the ethnic and cultural diversity within the region.

Comparisons of the outcomes on control, type of management and complications status in early onset and late onset type 2 diabetes in Asia.

OBJECTIVE: To describe the clinical characteristics and chronic diabetic complications in early (EOD) and late onset type 2 diabetes mellitus (LOD) in Asia. RESEARCH DESIGN AND METHODS: Retrospective collection of information (basic patient data, treatment received for diabetes, hypertension, dyslipidaemia, clinical measurements, complications, life-style management, etc.) on paper form and prospective collection of blood samples for HbA(1c) assessment were performed. Means, proportions and associated factors were analyzed using non-parametric and logistic regression. RESULTS: The frequency of EOD (<30 years) varies in different Asian countries (0.4-5.3%). Overweight (BMI>or=23 kg/m2) was common in both EOD (60%) and LOD (66%). EOD was characterized by significantly higher levels of HbA(1c) (median 8.9% versus 7.9%) and FPG (median 9.8 mmol/L versus 8.3 mmol/L) but hypertension was less common (43% versus 59%). Lipid profiles (cholesterol and triglycerides) were similar between both groups of patients. Cataract was more common in LOD and was associated with onset age and diabetes duration whereas an increase in frequency of advanced eye disease, retinopathy and history of photocoagulation was found in EOD cohort. CONCLUSIONS: In addition to diabetic control and duration of the disease, the onset age conferred risk to certain subsets of chronic complications in type 2 diabetes population.

The efficacy of repaglinide monotherapy and in combination with metformin in Indonesian type 2 diabetes mellitus patients.

AIM: To investigate the efficacy and safety of repaglinide alone and in combination with metformin therapy. METHODS: Seventy-two type 2 diabetes patients who were oral anti-diabetic drugs (OAD)-naive or currently on OAD for </=36 months with HbA1c </=9% and fasting plasma glucose (FPG) pound 13 mmol/L were recruited. Patients were titrated for 6 weeks to a dose level which maintained fasting blood glucose at 4.4-7.0 mmol/L and continued treatment for 8 weeks. Dose regimen started with 0.5 mg repaglinide each main meal, progressing to 1.0 mg repaglinide, 1.0 mg repaglinide + metformin 500 mg b.i.d. and 1.0 mg repaglinide + metformin 500 mg t.i.d., depending on patients' glycaemic status. Patients' glycaemic control (HbA(1c) and FPG), body weight and other safety parameters were evaluated. RESULTS: Thirty-seven patients completed the trial. Patients were overweight (mean BMI 25.5 +/- 4.1 kg/m(2)) with mean age 52.5 +/- 8.8 years and mean diabetes duration of 2.4 +/- 3.8 years. Mean HbA1c (2.26 +/- 0.22%, [p <0.05]) and FPG (3.31 +/- 0.47 mmol/L, [p <0.05]) decreased significantly from baseline. Body weight did not change significantly (0.85 +/-0.45 kg, p=0.068). Of the 33 patients who had baseline FPG >7.0 mmol/L, it appeared that repaglinide alone at doses 0.5 or 1.0 mg achieved FBG <7.0 mmol/L in 67% of patients. The majority of the treatment emergent adverse events were mild and unlikely related to trial product. Episodes of symptomatic hypoglycaemia were low (9.3%) in frequency. The changes in haematology, clinical biochemistry and urinalysis were mostly minor or remained unchanged. Vital signs and the results of physical examination also remained unchanged. Three of the four withdrawals were due to adverse events but were unlikely related to trial product. CONCLUSION: treatment with repaglinide alone and in combination with metformin was efficacious in glycaemic control in OAD-naive or previous users. Most of the patients appeared to achieve good control with repaglinide alone. The treatment regimens were safe (317 words).

The diagnostic value of combined risk factor analysis and radiological imaging in determining osteoporosis in post-menopausal women.

AIM: To determine the diagnostic value of risk factor analysis (age, duration of menopause, body mass index and physical activities) and radiological imaging (Singh index and cortical index of the femoral neck) in diagnosing osteoporosis in post-menopausal women. METHODS: The study was cross sectional on 64 post-menopausal women without secondary risk factor for osteoporosis. They were classified proportionally using the Singh index. Bone density was measured using DEXA (dual x-ray absorptiometry) on the femoral neck and lumbal 2-4 spine areas. The Singh index and cortical index of the femoral neck were evaluated using femoral neck antero-posterior x-ray. Physical activities were measured using a Historical leisure activity questionnaire. Bivariat statistical analysis was conducted using the t-test and chi-square, whereas multivariate analysis was conducted using multinomial logistic regression. RESULTS: There was a significant association (p<0.05) between bone density and age, body weight, height, body mass index, duration of menopause and Singh index. With multinomial logistic regression analysis, it was demonstrated that only Singh index, the duration of menopause and body mass index had the highest sensitivity and specificity. The score system algorithm could be utilized in two steps, the first was to diagnose osteoporosis and the second was to distinguish between osteopenia and normal bone. This score system had a sensitivity of 91.4% and a specificity of 89.6%, a positive prediction value of 91.4% in determining osteoporosis, and a sensitivity of 66.7%, a specificity of 89.1% and a positive prediction value of 70.6% in determining osteopenia, whereas the negative prediction value was 75%. CONCLUSION: The score system algorithm is the best method for determining osteoporosis in post-menopausal women. If there is osteopenia, evaluation using DEXA is then required. The score system algorithm cannot be used to follow up the therapy.

Left ventricular diastolic dysfunction in obese women.

AIM: To determine the direct effect of obesity on echocardiographic indices of diastolic left ventricular function METHODS: 44 obese (BMI > or =25 kg/m2) and 45 normal weight women were studied. They had no other pathological conditions. Echocardiographic indices of diastolic function were obtained, and dysfunction was assumed when at least two values differed by > or =2 SD from the normal weight group. RESULTS: In obese subjects, the values of maximum velocity of active mitral filling (A) were increased and pulmonary diastolic velocity was decreased significantly (p< 0,01); all other diastolic variables were unchanged. Subclinical diastolic dysfunction tend to be more prevalent among obese subjects but it was not significantly different from non obese (p= 0.11), being present in nine obese (20.5%) and 4 normal (8.9%) subjects. CONCLUSION: Subclinical left ventricular diastolic dysfunction is present in obese women.

Correlation between CD4 count and intensity of Candida colonization in the oropharynx of HIV-infected/ AIDS patient.

AIM: To know the correlation between CD4 count and intensity of Candida colonizations in the oropharynx of HIV-infected/AIDS patients, to get the prevalence of oropharyngeal candidiasis (OPC), and to know what kind of Candida species that causes oropharynx candidiasis of HIV-infected/AIDS patients. METHODS: A cross-sectional study was conducted in HIV-infected/AIDS patients who came as outpatients and inpatients in Cipto Mangunkusumo Hospital. The patients were interviewed, physically examined, their CD4 counts were checked, and their mouth rinse samples were taken to be cultured. Candida species was identified in CHROMagar media, and data were processed. RESULTS: From September 2004 until January 2005, 60 HIV-infected/AIDS patients were included in this study. There were 86.7% males and 13.3% females. Majority of the patients were from 20-30 years age group (85%). The most frequent transmission was among drug users (75%) followed by sexual contact (18.3%). The median of CD4 counts was 100 cells/il, ranged from 2 to 842 cells/il. Proportion of the OPC was 63.3% (CI 95% = 51.1 - 75.5). From 59 Candida isolates in this study, 74.58% were C. albicans. Candida non C. albicans species that were found in this trial were C. krusei, C. parapsilosis and C. tropicalis. There was significant correlation between low CD4 counts and high intensity of Candida colonization on the oropharynx of the subjects (r = -0.756). CONCLUSION: There was strong negative correlation (r = -0.756) between CD4 count and intensity of Candida colonization in the oropharynx of HIV-infected/AIDS patients. Proportion of OPC in this study was 63.3%. The most frequent species found in the oropharynx of the subjects was C. albicans.
