Objective: Acacia bark-derived proanthocyanidins exhibit antioxidant, anti-inflammatory, anti-diabetic, hypotensive effects, and improving skin condition, in addition to beneficial effects on blood glucose. Herein, we evaluated the effects of acacia bark-derived proanthocyanidins on fasting and postprandial blood glucose levels in healthy Japanese adults with fasting blood glucose (FBG) levels between 110–125 mg/dL.Methods: Subjects were randomly allocated into 2 groups (n = 33 per group) and consumed 6 tablets/day of either tablets of acacia bark extract containing proanthocyanidins (Acacia group) or placebo for 12 weeks. Evaluation points were at the screening, and after 4-week (4w), 8-week (8w), and 12-week intervention (12w). The primary outcome was FBG level at 12 w, whereas the secondary outcomes were FBG level at 4w and 8w, the FBG changes from Scr to each-week intervention, the percentage of subjects with FBG levels below 110 mg/dL after 12 w, the measured value and the change value from Scr to each-week intervention of HbA1c, the measured value and the change value from Scr to each-week intervention of postprandial blood glucose levels.Results: A total of 33 subjects (18 men, 15 women) from each group were analyzed. The Acacia group had significantly lower FBG levels at 8 and 12 w than the placebo group (P = 0.030 and P = 0.014, respectively). The percentage of subjects with FBG <110 mg/dL at 12 w was marginally higher in the Acacia group than in the placebo group (P = 0.079). HbA1c at 12 w was significantly lowered in the Acacia group compared to the placebo group (P = 0.015).Conclusions: Acacia bark-derived proanthocyanidins were confirmed to have FBG-lowering effects.Trial registration: UMIN000039414Foundation: Acacia-No-Ki Co.,Ltd.Keywords: Acacia bark extract, Proanthocyanidins, Fasting blood glucose level, HbA1c

Abstract Background : The extract of Andrographis paniculata (Burm. F.) Wall. Ex. Nees. (sambiloto) (穿心蓮 chuān xīn lián) has been reported to have antidiabetic effect on mice models and has been used traditionally in the community. The exact mechanism of sambiloto extract in decreasing plasma glucose is unclear, so we investigated the role of sambiloto extract in incretin pathway in healthy and prediabetes subjects.Methods: This study was a double-blind, cross-over, randomized placebo-controlled trial. It was conducted to 38 healthy and 35 prediabetes subjects. All subjects were exposed to both intervention sambiloto extract and placebo alternately. All subjects were randomly assigned to receive first intervention for 14 days. There was wash out period between subsequent intervention. Primary outcome was glucagon-like peptide 1 (GLP-1) concentration and secondary outcomes were fasting insulin, 2-hour postprandial insulin, homeostasis model assessment of insulin resistance (HOMA-IR), fasting blood glucose, 2-hour postprandial blood glucose, dipeptidyl peptidase-4 (DPP-4), and glycated albumin before and after intervention.Result: After the intervention, GLP-1 concentration significantly increased in prediabetes by 19.6% compared to the placebo (p = 0.043). There were no significant differences in the changes of fasting insulin, 2-hour postprandial insulin, HOMA-IR, fasting blood glucose, 2-hour postprandial blood glucose, DPP-4, and glycated albumin levels after intervention. Sambiloto extract did not inhibit DPP-4 enzyme in healthy and prediabetes subjects. Conclusion: Sambiloto extract increased GLP-1 concentration without inhibiting DPP-4 enzyme in prediabetes subjects.Trial Registration : Clinical Trials.gov ID : NCT03455049.

Background: Obesity cause various physiological changes in the body, one of which is insulin resistance causes high blood glucose levels. Chewing is a stimulus of cephalic phase responses and sensory stimulation that can increase hormones releasing such as insulin, ghrelin, cholecystokinin (CCK) and glucagon like peptide-1 (GLP-1). Chewing plays important role in determining postprandial plasma glucose concentration.Objective: Investigate the effect of chewing on postprandial blood glucose in obese adults.Method: This was true experimental research. Research subjects were treated in the form of chewing 22 times and 40 times each mouthful. Blood glucose levels were measured using glucometer on fasting blood glucose and postprandial blood glucose 15 minutes, 30 minutes, 60 minutes, and 120 minutes. Statistical test using Independent t-test.Results: The mean postprandial glucose levels in the 22 chews group at 15 minutes, 30 minutes, 60 minutes, and 120 minutes were 112.11 ± 14.3328, 126.11 ± 15.667, 116.94 ± 15.539, and 89.67 ± 11.668 . While the mean postprandial blood glucose levels in the 40 chews group at 15 minutes, 30 minutes, 60 minutes, and 120 minutes were 122.22 ± 14.381, 129.61 ± 15.112, 109.50 ± 14.995, and 85.83 ± 13.963. There were statistically significant differences between chewing groups 22 times and chewing 40 times on fasting blood glucose and 15 minutes postprandial blood glucose (p = 0.041 and p = 0.042), while on 30 minutes postprandial glucose testing, 60 minutes , and 120 minutes there was no significant difference (p> 0.05).Conclusion: There was significant differences in 15 minutes postprandial blood glucose level between group 22 times chewing and 40 times chewing each mouthful.

Abstract Desvenlafaxine is a potent selective serotonin and norepinephrine reuptake inhibitor used to treat depression and anxiety. Several antidepressants have been associated with drug-induced hyperglycemia, but currently there are no reports for desvenlafaxine. A case of suspected desvenlafaxine-induced hyperglycemia is presented involving a 59-year-old female with type 2 diabetes whose average blood glucose increased by 30 mg/dL for fasting blood glucose and 75 mg/dL for postprandial blood glucose 1 month after switching from venlafaxine to desvenlafaxine. Prior to starting desvenlafaxine, she was stable on metformin 1000 mg twice daily, insulin glargine 8 units daily, and dulaglutide 1.5 mg once weekly. Over the course of 3 months after desvenlafaxine initiation, insulin glargine was increased and insulin lispro was initiated as the patient refused alternative antidepressant therapy due to favorable improvements in anxiety and depression. No other cause for elevated blood glucose could be elucidated. The Naranjo scale resulted in a score of 3, indicating a possible cause for the adverse drug reaction. Antidepressants have been associated with glucose dysregulation. However, literature also demonstrates improved glycemic control in treated versus untreated depression. If altered glucose levels are noted, all potential causative factors should be evaluated and risks and benefits weighed to guide therapy.

Background: To prevent diabetes, it is important to control postprandial glycemic levels. Studies have suggested that consuming black tea decreases the risk of type 2 diabetes; however, only a few studies have examined the effects of black tea on postprandial glycemic control after consuming starch-rich foods. In addition, the mechanism underlying the suppression of postprandial glucose levels remains unclear.Objective: To investigate the effects of black tea on postprandial blood glucose levels in healthy humans and to identify the components of black tea that inhibit digestive enzymes.Methods: The inhibitory activity of black tea on digestive enzymes was measured, and the inhibitory components were fractionated. Healthy Japanese adults ingested 200 ml of black tea, and its effect on postprandial blood glucose and insulin levels were investigated. Results: Black tea dose-dependently inhibited α-glucosidase, sucrase, and α-amylase activity. The major components responsible for this inhibition were high–molecular-weight polyphenols. The galloyl moieties present in these compounds play an important role in their inhibitory activities. Two randomized, double-blind, placebo-controlled, crossover studies of healthy human subjects (total n = 46) were conducted to investigate the effect of black tea on blood glucose and insulin levels. Combined data from the two studies showed that black tea ingestion (200 mL) after cooked rice intake (200 g) significantly reduced the incremental area under the curve of glucose (P =.024) and insulin (P =.014) compared to placebo drink.Conclusions: The high–molecular-weight polyphenols in black tea inhibited α-glucosidase, sucrase, and α-amylase activity in a dose-dependent manner. Furthermore, black tea ingestion after eating cooked rice significantly reduced the incremental area under the curve of glucose and insulin. These effects of black tea could be attributed to the inhibition of digestive enzymes by high–molecular-weight polyphenols containing galloyl groups.Keywords: black tea, blood glucose, α-glucosidase, α-amylase, polyphenol

In the present study, we evaluated the hypoglycemic, hypolipidemic and anti-peroxidative effects of yam rice powder (YRP) derived from Tremella aurantialba on streptozotocin (STZ)-induced diabetic mice and diabetic patients. Diabetic mice were treated with ethanol extract of YRP (EEYR) at three doses or YRP for 30 days. Diabetic patients were treated with ethanol extract solution of YRP (ESYR) for 4.5 months. Results indicated that EEYR administration significantly reduced levels of fasting blood glucose (FBG), serum fructosamine, total cholesterol, total triglyceride and malondialdehyde, and increased glucose metabolism velocities and superoxide dismutase level in the serum compared with diabetic controls (p<0.01). Moreover, ESYR could replace chemical drugs to control the FBG and postprandial blood glucose levels of diabetic patients. Our results suggested that YRP could enhance hypoglycemic, hypolipidemic and antioxidant properties in STZ-induced diabetic mice and diabetic patients. Collectively, YRP might be used as food to prevent or manage diabetes.

Background and objectives. Gluten-related disease affects less than 1% population and is not considered of relevance at the public health level. However, the consumption of a gluten-free diet has been most commonly adopted as a special diet worldwide in the recent past. In the present study, we investigated the association of gluten intake and diabetic Wistar albino rats. Methods. Thirty adult Wistar rats were randomly divided into five groups: control, diabetic, and test treated with pure gluten (100, 200 and 400 mg/kg body weight). Diabetes was induced in rats by intraperitoneal injection of Streptozotocin (65 mg/kg) after a dose of nicotinamide (110 mg/kg). Body weight, fasting blood glucose levels, postprandial blood glucose levels and histopathology of the pancreas were compared. Results. Fasting blood glucose levels and postprandial blood glucose were significantly higher in diabetes animals but there were no significant changes in gluten treated groups. Other parameters were not significantly changed among different groups. Conclusions. Gluten at doses 100 mg/kg, 200 mg/kg and 400 mg/kg is not a diabetogenic diet and hence it needs not be excluded from diet for the prevention and management of Type 2 diabetes mellitus.

Result. After the intervention, GLP-1 concentration significantly increased in prediabetes by 19.6% compared to the placebo ( p = 0.043 ). There were no significant differences in the changes of fasting insulin, 2-hour postprandial insulin, HOMA-IR, fasting blood glucose, 2-hour postprandial blood glucose, DPP-4, and glycated albumin levels after the intervention. Sambiloto extract did not inhibit the DPP-4 enzyme in healthy and prediabetic subjects. Conclusion. Sambiloto extract increased GLP-1 concentration without inhibiting the DPP-4 enzyme in prediabetic subjects.

Background: This article provides a clinical update using a novel run-to-run algorithm to optimize prandial insulin dosing based on sparse glucose measurements from the previous day's meals. The objective was to use a refined run-to-run algorithm to calculate prandial insulin-to-carbohydrate ratios (I:CHO) for meals of variable carbohydrate content in subjects with type 1 diabetes (T1DM). Method: The open-labeled, nonrandomized study took place over a 6-week period in a nonprofit research center. Nine subjects with T1DM using continuous subcutaneous insulin infusion participated. Basal insulin rates were optimized using continuous glucose monitoring, with a target fasting blood glucose of 90 mg/dl. Subjects monitored blood glucose concentration at the beginning of the meal and at 60 and 120 minutes after the start of the meal. They were instructed to start meals with blood glucose levels between 70 and 130 mg/dl. Subjects were contacted daily to collect data for the previous 24-hour period and to give them the physician-approved, algorithm-derived I:CHO ratios for the next 24 hours. Subjects calculated the amount of the insulin bolus for each meal based on the corresponding I:CHO and their estimate of the meal's carbohydrate content. One- and 2-hour postprandial glucose concentrations served as the main outcome measures. Results: The mean 1-hour postprandial blood glucose level was 104 ± 19 mg/dl. The 2-hour postprandial levels (96.5 ± 18 mg/dl) approached the preprandial levels (90.1 ± 13 mg/dl). Conclusions: Run-to-run algorithms are able to improve postprandial blood glucose levels in subjects with T1DM.
