Increased vegetable intake improves glycaemic control in adults with type 2 diabetes mellitus: a clustered randomised clinical trial among Indonesian white-collar workers.

Dietary patterns high in fibre and green leafy vegetables have shown an inverse association with lower risks of type 2 diabetes mellitus and improved glycaemic control. The study aimed to investigate the effects of increased vegetable intake and conventional diabetes diet on glycaemic control among type 2 diabetic patients. White-collar workers from one telecommunication company with type 2 diabetes were assigned to two treatment groups by cluster randomisation. Individuals with known type 2 diabetes and poor glycaemic control (HbA1c ≥8 g%) were eligible and a total of 84 subjects were recruited. Subjects in the intervention group (n 41) were offered to attend seminars and intensive coaching weekly to encourage them to increase raw vegetable intake. The control group (n 40) followed the conventional diet according to the guidelines of the Indonesian Society of Endocrinology. Glycated haemoglobin (HbA1c), plasma lipids, blood pressure, vegetable intake and anthropometric measurements were assessed at baseline and end line of 12 weeks intervention. A regression analysis was conducted using differences in HbA1C between baseline and 12 weeks as the dependent variable. Student's t test was conducted for the changes of biochemical indicators from baseline to end line during the period of 12 weeks intervention. Glycaemic control improved in the intervention group and mean HbA1C, fasting blood glucose and post-prandial blood glucose in the intervention group decreased significantly along with body weight, waist circumference and total cholesterol. The finding suggested that the intervention which emphasised raw vegetable intake contributed to improved glycaemic control among Indonesian adults with type 2 diabetes mellitus.

Assessment of baseline characteristics, glycemic control and oral antidiabetic treatment in Asian patients with diabetes: The Registry for Assessing OAD Usage in Diabetes Management (REASON) Asia study.

BACKGROUND: To assess baseline characteristics, glycemic control, and treatment with oral antidiabetic drugs (OAD) in type 2 diabetes mellitus (T2DM) patients. METHODS: This multinational, observational study recruited patients ≥ 21 years of age who were newly diagnosed and/or treated with OAD monotherapy for <6 months but were inadequately controlled. In cross-sectional phase, data on demographics, medical history, diabetic complications and comorbidities, OAD treatment, glycosylated hemoglobin (HbA1c), and fasting blood glucose (FBG) were collected. In longitudinal phase evaluating 6-month follow-up of sulfonylurea (SU)-treated patients, additional data on reasons for not achieving HbA1c targets were collected. RESULTS: Of 1487 patients (mean [± SD] age 52.0 ± 11.6 years; 46.7% men; mean BMI 25.8 ± 4.4 kg/m(2) ) recruited, 75.9% were newly diagnosed, 73.3% had central obesity, 43.8% had hypertension, and 60.5% had dyslipidemia. The mean HbA1c was 9.8 ± 2.4%, and the mean FBG was 11.3 ± 4.3 mmol/L. At T0 (baseline) and T6 (month 6 visit), 99.8% (n=1066) and 97.1% (n=830) patients received SU, respectively. There was decrease from T0 to T6 in mean HbA1c (10.2% vs 7.3%, respectively; P<0.0001) and mean FBG (12.0 vs 7.6 mmol/L, respectively; P<0.0001). Number of patients with HbA1c <7% increased from T0 (4.5%) to T6 (46.8%). Reasons for not achieving target HbA1c included poor diabetes education (50.7%), non-compliance to OADs (21.4%), and fear of hypoglycemia (19.7%). CONCLUSION: Marked reductions in HbA1c and FBG are achievable in T2DM patients managed with OADs. However, patient education and compliance are important for achieving and maintaining treatment targets.

The traditional plant, Andrographis paniculata (Sambiloto), exhibits insulin-releasing actions in vitro.

AIM: to examine the effect of A.paniculata on pancreatic b-cells. METHODS: sixty minutes incubation of BRIN-BD11 in Modified Kreb-Ringer Solution containing 16.7 mM glucose (KRB-3) + 0.625 - 2.5 mg/mL A.paniculata evoked 1.7 - 3.73 fold of insulin secretion compared to 16.7 mM glucose only (p = 0.003 - p < 0.001). RESULTS: compared to the effect of 100 mM glibenclamide, 60 minutes incubation of BRIN-BD11 in KRB-3 containing 1.25 and 2.5 mg/mL A. paniculata evoked 1.5 fold (p=0.034) and 2.3 fold (p=0.001) insulin secretion. Twenty minutes incubation of BRIN-BD11 in KRB-3 + 0.625-5 mg/mL A.paniculata, evoked 1.4 - 4.7 fold (p = 0.002 - p < 0.001) of insulin secretion compared to 16.7 mM glucose only. Twenty minutes incubation of BRIN-BD11 in KRB-1 containing 1.11 mM glucose + 0.625 - 10 mg/mL A.paniculata, evoked 1.3 - 3.7 fold (p = 0.019 - p < 0.001) of insulin secretion compared to 16.7 mM glucose only. CONCLUSION: this study conclude that A.paniculata was a very strong, dose dependent insulinotropic agent, glucose dependent and independent insulin secreting agent. This study also conclude that A.paniculata affected one of the membrane receptors, mostly ATP-dependent potassium channels (K+ATP).

Imported malaria in Jakarta, Indonesia: passive surveillance of returned travelers and military members postdeployment.

BACKGROUND: Autochthonous malaria does not currently occur in Jakarta, the most populous city in Indonesia. Military, forestry, mining, and tourist activities draw Jakarta residents to distant parts of the archipelago with high rates of malaria. Although malaria is a reportable disease in Jakarta, little has been published. METHODS: We collected demographic and travel information from patients in Jakarta with microscopically confirmed malaria from January 2004 to February 2005, using a standardized data collection form. These results were compared to regional rainfall statistics and transit patterns of Jakarta residents to and from rural areas. RESULTS: Data from 240 patients were collected. Aceh Province was the travel destination most commonly recorded for military members, while Papua and Bangka Island were the most frequently cited by civilians. Plasmodium falciparum accounted for 53% of cases, of which 15% had detectable gametocytemia. The most common admission diagnoses were malaria (39%), febrile illness not otherwise specified (23%), viral hepatitis (19%), and dengue (11%). The median time from admission to microscopic diagnosis was 2 days for civilian patients and 2.5 days for military patients. The highest number of cases occurred in May, July, and December with the nadir in October. CONCLUSIONS: The diagnosis of malaria may be overlooked and therefore delayed, in nonendemic areas such as Jakarta. Travel destinations associated with contracting malaria vary significantly for civilian and military populations. The factors affecting the peak months of importation likely include rainfall, holiday transit, military flight availability, and referral center locations.
