Intensive attention improves glycaemic control in insulin-dependent diabetes without further advantage from home blood glucose monitoring: results of a controlled trial.

Forty-six diabetics treated with twice-daily insulin were seen every two weeks for six months in an intensive education programme aided by regular home urine glucose testing. Control was improved with a decrease in 24-hour urinary glucose excretion (median 138 mmol/24 h (24.8 g/24 h) falling to 70 mmol/24 h (12.6 g/24 h); p less than 0.002), glycosylated haemoglobin concentration (mean 11.4 +/- SD 2.3% falling to 10.4 +/- 1.5%; p less than 0.001), and Diastix score (median 3.0 falling to 1.3; p less than 0.001). There was no reported increase in hypoglycaemia. Thirty-eight of the diabetics proceeded to a nine-month randomised cross-over study of the effect on blood glucose control of monitoring urinary glucose or blood glucose measured visually or by a reflectance meter using appropriate reagent strips. No further improvement in control was observed after home blood glucose monitoring. Nevertheless, 29 out of 37 patients preferred blood to urine glucose monitoring. During both the education and cross-over studies there was evidence of an initial improvement in control followed by deterioration. This was independent of the monitoring method used in the cross-over period and may have been due to waning enthusiasm. Despite patient enthusiasm and other reports to the contrary, home blood glucose monitoring offered no improvement in control over intensive attention and conventional urine glucose monitoring.     

Efficacy of self monitoring of blood glucose in patients with newly diagnosed type 2 diabetes (ESMON study): randomised controlled trial

Objectives To assess the effect of self monitoring of blood glucose concentrations on glycaemic control and psychological indices in patients with newly diagnosed type 2 diabetes mellitus.Design Prospective randomised controlled trial of self monitoring versus no monitoring (control).Setting Hospital diabetes clinics.Participants 184 (111 men) people aged <70 with newly diagnosed type 2 diabetes referred to the participating diabetes clinics. Major exclusion criteria were secondary diabetes, insulin treatment, previous self monitoring of blood glucose.Interventions Participants were randomised to self monitoring or no monitoring (control) groups for one year with follow-up at three monthly intervals. Both groups underwent an identical structured core education programme. The self monitoring group received additional education on monitoring.Main outcome measures Between group differences in HbA_1c, psychological indices, use of oral hypoglycaemic drugs, body mass index (BMI), and reported hypoglycaemia rates.Results 96 patients (55 men) were randomised to monitoring and 88 (56 men) to control. There were no baseline differences in mean (SD) age (57.7 (11.0) in monitoring group v 60.9 (11.5) in control group) or HbA_1c (8.8 (2.1)% v 8.6 (2.3)%, respectively). Those in the monitoring group had a higher baseline BMI (34 (7) v 32 (6.2)). There were no significant differences between groups at any time point (12 months values given) in HbA_1c (6.9 (0.8)% v 6.9 (1.2)%, P=0.69; 95% confidence interval for difference −0.25% to 0.38%), BMI (33.1 (6.4) v 31.8 (6.0); adjusted for baseline BMI, P=0.32), use of oral hypoglycaemic drugs, or reported incidence of hypoglycaemia. Monitoring was associated with a 6% higher score on the depression subscale of the well-being questionnaire (P=0.01).Conclusions In patients with newly diagnosed type 2 diabetes self monitoring of blood glucose concentration has no effect on glycaemic control but is associated with higher scores on a depression subscale.Trial registration ISRCTN 49814766.     

White coat hyperglycaemia: disparity between diabetes clinic and home blood glucose concentrations.

OBJECTIVES--To identify patients with discrepantly high clinic blood glucose concentrations compared with self reported values and to assess whether such patients have errors in self monitoring technique. To determine whether, in patients with good technique, the discrepancy is a transient phenomenon related to clinic attendance. DESIGN--Prospective study of diabetes clinic patients recruited over six months. SETTING--Outpatient diabetes clinic of a teaching hospital. SUBJECTS--34 consecutive patients with non-insulin dependent diabetes who had had at least two consecutive clinic blood glucose concentrations more than 5 mmol/l higher than the mean self reported concentration. MAIN OUTCOME MEASURES--Assessment of monitoring technique; presence of cognitive or physical impairment; serum fructosamine concentration; home and clinic blood glucose concentrations. RESULTS--15 of 34 patients had errors in monitoring technique, 12 of whom had cognitive or physical impairment. In the remaining 19, the mean (SD) blood glucose concentrations of capillary and venous samples taken at home (10.2 (0.6) and 12.2 (1.1) mmol/l respectively) were significantly lower than in those taken at the clinic (16.8 (1.6) mmol/l, p < 0.0002). The fructosamine concentration was significantly higher in patients with monitoring errors than those without (2.4 (0.4) v 1.8 (0.4) mmol/l, p < 0.0001). CONCLUSIONS--"White coat" hyperglycaemia was detected in about half the patients but errors in technique accounted for the rest of the discrepancies. Patients'' ability should be assessed before teaching self monitoring and the technique checked regularly.     

Cost effectiveness of self monitoring of blood glucose in patients with non-insulin treated type 2 diabetes: economic evaluation of data from the DiGEM trial

Objective To assess the cost effectiveness of self monitoring of blood glucose alone or with additional training in incorporating the results into self care, in addition to standardised usual care for patients with non-insulin treated type 2 diabetes.Design Incremental cost utility analysis from a healthcare perspective. Data on resource use from the randomised controlled diabetes glycaemic education and monitoring (DiGEM) trial covered 12 months before baseline and 12 months of trial follow-up. Quality of life was measured at baseline and 12 months using the EuroQol EQ-5D questionnaire.Setting Primary care in the United Kingdom.Participants 453 patients with non-insulin treated type 2 diabetes.Interventions Standardised usual care (control) compared with additional self monitoring of blood glucose alone (less intensive self monitoring) or with training in self interpretation of the results (more intensive self monitoring).Main outcome measures Quality adjusted life years and healthcare costs (sterling in 2005-6 prices).Results The average costs of intervention were £89 (€113; $179) for standardised usual care, £181 for less intensive self monitoring, and £173 for more intensive self monitoring, showing an additional cost per patient of £92 (95% confidence interval £80 to £103) in the less intensive group and £84 (£73 to £96) in the more intensive group. No other significant cost difference was detected between the groups. An initial negative impact of self monitoring on quality of life occurred, averaging −0.027 (95% confidence interval−0.069 to 0.015) for the less intensive self monitoring group and −0.075 (−0.119 to −0.031) for the more intensive group.Conclusions Self monitoring of blood glucose with or without additional training in incorporating the results into self care was associated with higher costs and lower quality of life in patients with non-insulin treated type 2 diabetes. In light of this, and no clinically significant differences in other outcomes, self monitoring of blood glucose is unlikely to be cost effective in addition to standardised usual care.Trial registration Current Controlled Trials ISRCTN47464659.     

Development of urine glucose meter based on micro-planer amperometric biosensor and its clinical application for self-monitoring of urine glucose

The highly sensitive urine glucose meter based on amperometric glucose sensor was developed and commercialized. It shows remarkable performances of wide measurement range in 0-2000 mgdl(-1), rapid response time as 6s and robustness against influence by interferents like ascorbic acid or acetaminophen. Correlation between the developed urine glucose meter and commercialized clinical-use urine glucose analyzer showed excellent linear relationship. The monitoring of postmeal blood glucose levels by assess of urine glucose of actual subjects was performed with the developed urine glucose meter. The experimental results suggest the urine glucose level 120 min following the meal should be the appropriate index for diabetes or impaired glucose tolerance to control blood glucose level. The new portable meter was developed, and is expected for flexible use at places other than home or office.     

Urine glucose levels are disordered before blood glucose level increase was observed in Zucker diabetic fatty rats

Many patients with diabetes are not diagnosed at all or are diagnosed too late to be effectively treated, resulting in nonspecific symptoms and a long period of incubation of the disease. Pre-diabetes is an early warning signal of diabetes, and the change of urine glucose in this period has been ignored even though urine has long been related with diabetes. In this study, Zucker diabetic fatty (ZDF) rats were used to test if there were changes in urine glucose before blood glucose increases. Six 8-week-old male ZDF rats (fa/fa) and Zucker lean (ZL) rats (fa/+) were fed with Purina 5008 high-fat diet and tested for fasting blood glucose and urine glucose. After 12 weeks of feeding, the urine glucose values of the ZL rats were normal (0–10 mmol L~(-1)), but the values of the ZDF model rats increased 10 weeks before their blood glucose levels elevated. The urine glucose values of the ZDF model rats showed a state of disorder that was frequently elevated (10 mmol L~(-1)) and occasionally normal (0–10 mmol L~(-1)). This finding may provide an easy early screening for diabetes by long-term monitoring of urine glucose levels: pre-diabetes may be revealed by frequently disordered urine glucose levels over a period.     

Aglycosuric Diabetes

The usefulness of urine tests for glucose was compared with that of blood sugar determinations in detecting diabetes mellitus in 2000 medical outpatients. Eighty-five patients proved to be diabetic, but 33 of these had no glycosuria on their first visit and would not have been detected by laboratory tests had the blood glucose levels not been measured. Exactly one-half of the new diabetics discovered would have been missed (15 of 30) had only urine tests been performed. The new diabetics who were aglycosuric at their initial examination had a mild form of the disease, were predominantly elderly, and were controlled, in nearly every case, by diet alone. Most of these patients had evidence of an elevated renal threshold for glucose. These results indicate that there is a large group of patients with mild, asymptomatic, diabetes mellitus who remain undetected unless blood tests are employed routinely. Because they have little or no glycosuria these patients do not have polydipsia, polyphagia, polyuria, or loss of weight. Automation in the medical laboratory has made routine blood tests for glucose feasible and rewarding in detecting diabetes mellitus.     

How do we educate young people to balance carbohydrate intake with adjustments of insulin?

The dietary management of childhood diabetes is complex. Is it possible to educate young people to balance carbohydrate with their insulin? Can dietary knowledge be translated into lasting behaviour change? Do present teaching methods provide the skills necessary for children and parents to adjust their insulin therapy adequately? Evidence shows great variation in glycaemic control between centres and countries but the impact of dietary education methods is poorly evaluated and its links with clinical and psychosocial outcomes is virtually unknown. There is also little evidence to suggest cohesive teamworking with clear dietary targets for glycaemic control, lipids, incidence of hypoglycaemia, compliance, effect on peer and sibling relationships, and evaluation of individual dietary components, e.g. fibre, fat, antioxidants. There is wide variation in methods of dietary education, which are often based on historic practice. They include rigid counting of grams of carbohydrate, carbohydrate portion assessments, qualitative diets, low glycaemic index diets and the more recent 'intensified' carbohydrate measures with daily adjustments of insulin (the basis also of pump management). This last method has many benefits although it requires extensive nutrition education, it allows greater flexibility and variety of food intake, is sensitive to the varying daily energy expenditure of childhood and it addresses postprandial glycaemic excursions, all of which are inadequately managed by conventional therapy. However, one of the problems of overemphasizing carbohydrate measurement is that total carbohydrate intake may be suppressed, with a resulting increase in fat, this may contribute to an increase in cardiovascular risk. The ISPAD Consensus Guidelines 2000 contain dietary recommendations but scientific evidence is often lacking. Limited dietary studies show that some countries can meet guidelines more successfully than others. There are many reasons for this, such as food availability, types of food eaten, food preferences and family/cultural/religious influences. Educational methods must be adapted to local customs. Is there enough evidence to recommend a particular dietary education method? What outcomes do we hope to achieve? The workshop explored these issues in order to develop a deeper understanding of the complexity of dietary modification in childhood diabetes.     

New Indices for Predicting Glycaemic Variability

Blood glucose variability is known to be associated with increased risk of long-term complications. Reliable indices for predicting hyperglycaemic and hypoglycaemic fluctuations are therefore needed. Glycaemic standard deviation (SD) obtained by continuous glucose monitoring correlates closely with nine previously described glycaemic variability formulas. Here, new indices predictive of glycaemic variability were developed, which can be calculated from laboratory measures based on a single blood draw. The indices included the glycated albumin (GA) to HbA1c ratio (GA/A1c ratio) and the fasting C-peptide immunoreactivity (FCPR) to fasting plasma glucose (FPG) ratio (FCPR index). Predictive values of these indices were assessed in 100 adults with diabetes. GA/A1c ratio and FCPR index showed close associations with glycaemic SD in addition to the nine existing glucose variability formulas. Subjects with a GA/A1c ratio ≥2.8 and FCPR index <3.0 showed the greatest SD and longest durations of hypoglycaemia, while those with a GA/A1c ratio <2.8 and FCPR index ≥3.0 had smaller SDs and little sign of hypoglycaemia. In adults with diabetes, a high GA/A1c ratio and low FCPR index value reflect higher glycaemic excursions, irrespective of diabetes type. Simultaneous measurements of GA, HbA1c, FPG and FCPR may help to identify a group of patients who warrant closer monitoring in relation to glycaemic variability and hypoglycaemia.     

Biotechnological and administration innovations in insulin therapy

The importance of the intensive control of blood glucose in patients with diabetes has been well documented in several large scale studies. Attempts to attain strict glucose control when managing diabetes have traditionally utilized daily subcutaneous injections of human insulin. This strategy has offered improvements in glycaemic control but is unable to replicate fully the normal diurnal plasma profile of endogenous human insulin. Advances in protein engineering techniques have, however, resulted in the formulation of a number of insulin analogues that offer more desirable properties of absorption from the subcutaneous depot and hence improved insulin profiles in patients with diabetes. Concurrent to the development of insulin analogues, devices to deliver insulin either subcutaneously or by other routes have also advanced. These novel delivery strategies are also likely to contribute to improved glycaemic control for patients with diabetes in the future.     

Oxidative DNA damage and plasma antioxidant capacity in type 2 diabetic patients with good and poor glycaemic control

Diabetes mellitus is a complex metabolic disorder characterized by a disturbance in glucose metabolism. Recent evidence suggests that increased oxidative damage as well as reduction in antioxidant capacity could be related to the complications in patients with type 2 diabetes. The aim of this study was to measure plasma antioxidant status in type 2 diabetic patients with good and poor glycaemic control and its relationship with oxidative DNA damage. Thirty-nine type 2 diabetic patients and eighteen healthy subjects were recruited for this study. We found that diabetic patients had slightly, but not significantly lower antioxidant capacity, measured with the "ferric reducing ability of plasma" (FRAP) assay, than healthy subjects. On the contrary, oxidative DNA damage (measured by the Comet assay) in leukocytes obtained from diabetic patients was significantly higher compared to healthy subjects. Taking into account glucose control, we found that the FRAP level was significantly (p<0.05) lower in diabetic subjects with poor glycaemic control than healthy subjects, while patients with good glycaemic control had FRAP values similar to controls. We also observed an unexpected positive correlation between FRAP values and oxidative DNA damage in diabetic patients; moreover, a positive correlation was found between FRAP and glucose level or HbA(1c) in patients with poor glycaemic control. In conclusion, our results confirm that patients with type 2 diabetes have a higher oxidative DNA damage than healthy subjects and that plasma antioxidant capacity is significantly lower only in patients with poor glycaemic control, moreover, in these patients FRAP values are positively correlated with glycaemic levels and HbA(1c). These observations indicate that a compensatory increase of the antioxidant status is induced as a response to free radical overproduction in type 2 diabetes. Therefore, the addition of antioxidant supplements to the current pharmacological treatment could have potentially beneficial effects in diabetic patients with poor glycaemic control.     

Management of severely brittle diabetes by continuous subcutaneous and intramuscular insulin infusions: evidence for a defect in subcutaneous insulin absorption.

Severely brittle diabetes is defined as a rare subtype of insulin-dependent diabetes with wide, fast, unpredictable, and inexplicable swings in blood glucose concentration, often culminating in ketoacidosis or hypoglycaemic coma. To assess the role of inappropriate type, amount, or timing of insulin treatment and the route of administration as a cause of severe brittleness six patients with continuous subcutaneous insulin infusion, which provides a high degree of optimisation of dosage with exogenous insulin in stable diabetics. The glycaemic control achieved during continuous subcutaneous insulin infusion was compared with that during continuous intramuscular insulin infusion. Six patients with non-brittle diabetes were also treated by continuous subcutaneous insulin infusion. These patients achieved the expected improvement in glycaemic control (mean +/- SD plasma glucose concentration 5.1 +/- 2.3 mmol/l (92 +/- 41 mg/100 ml)), but not the patients with brittle diabetes remained uncontrolled with continuous subcutaneous infusion (13.6 +/- 5.8 mmol/1 (245 +/- 105 mg/100 ml) compared with 10.3 +/- 4.1 mmol/l (186 +/- 74 mg/100 ml) during treatment with optimised conventional subcutaneous injections). During continuous intramuscular infusion, however, glycaemic control in five of the patients with brittle diabetes was significantly improved (7.7 +/- 2.6 mmol/l (139 +/- 47 mg/100 ml). The remaining patient with brittle diabetes, previously safely controlled only with continuous intravenous insulin, did not respond to continuous intramuscular infusion. It is concluded that in five of the six patients with brittle diabetes studied here impaired or irregular absorption of insulin from the subcutaneous site played a more important part in their hyperlability than inappropriate injection strategies. This absorption defect was presumably bypassed by the intramuscular route.

Cultural and clinical effectiveness of the 'QAAMS' point-of-care testing model for diabetes management in Australian aboriginal medical services

The national Quality Assurance for Aboriginal Medical Services (QAAMS) Program, in which point-of-care testing (POCT) for haemoglobin A(1c) (HbA(1c)) and urine albumin: creatinine ratio (ACR) is performed for diabetes management in 65 Australian Aboriginal medical services, is now embedded in the practice of diabetes care across Indigenous Australia. This paper documents the results of a detailed survey to assess levels of satisfaction with the QAAMS HbA(1c) Program among three key stakeholder groups-doctors, POCT operators and patients with diabetes. Both doctors and patients with diabetes agreed that the immediacy of POCT results contributed positively to patient care, improved the doctor-patient relationship, and made the patient more likely to be both compliant and self-motivated to improve their diabetes control. Both POCT operators and patients with diabetes reported improved satisfaction with their diabetes services after the introduction of POCT. The paper also provides evidence from two participating medical services that POCT has been an effective tool in improving the delivery of pathology services and clinical outcomes for both individuals and groups of patients with diabetes. A statistically significant reduction in HbA(1c) from 9.3% (+/- 2.0) to 8.6% (+/- 2.0) was observed in 74 diabetes patients 12 months after commencing POCT (p = 0.003, paired t-test). An improvement in the percentage of patients achieving glycaemic targets and a reduction in the percentage of patients with poor control was also observed in this group. These data provide evidence that the QAAMS POCT model delivers a culturally and clinically effective service for diabetes management in Aboriginal Australia.     

Impact of dietary fibre-enriched ready-to-eat extruded snacks on the postprandial glycaemic response of non-diabetic patients

Food intervention is a financially sensible way for prevention and treatment of diabetes. Extruded snack foods are considered high glycaemic products. Our previous research illustrated that postprandial glycaemic responses to snacks are manipulated by altering dietary fibre and starch contents. The current research assessed the effect of psyllium and oat bran on postprandial glycaemia and in?vitro digestibility. Addition of psyllium fibre to extruded snack products significantly reduced both the in?vitro and in?vivo glycaemic responses of products compared to a control snack product recipe. Oat bran inclusion reduced in?vitro starch digestibility but not in?vivo glycaemic response. The inclusion of oat bran into the snack products appeared to extend the glycaemic response of individuals compared to the control snack, suggesting a possibility of prolonging glucose release and potentially affecting satiety responses. The positive effect in attenuating glucose response means that psyllium fibre could be a target for inclusion by the snack food industry to effectively manipulate postprandial glucose response of individuals.     

Pain Reduction and Financial Incentives to Improve Glucose Monitoring Adherence in a Community Health Center

Self-monitoring of blood glucose is a critical component of diabetes management. However, patients often do not maintain the testing schedule recommended by their healthcare provider. Many barriers to testing have been cited, including cost and pain. We present a small pilot study to explore whether the use of financial incentives and pain-free lancets could improve adherence to glucose testing in a community health center patient population consisting largely of non-English speaking ethnic minorities with low health literacy. The proportion of patients lost to follow-up was 17%, suggesting that a larger scale study is feasible in this type of setting, but we found no preliminary evidence suggesting a positive effect on adherence by either financial incentives or pain-free lancets. Results from this pilot study will guide the design of larger-scale studies to evaluate approaches to overcome the variety of barriers to glucose testing that are present in disadvantaged patient populations.     

Heparanase levels are elevated in the urine and plasma of type 2 diabetes patients and associate with blood glucose levels

Heparanase is an endoglycosidase that specifically cleaves heparan sulfate side chains of heparan sulfate proteoglycans. Utilizing an ELISA method capable of detection and quantification of heparanase, we examined heparanase levels in the plasma and urine of a cohort of 29 patients diagnosed with type 2 diabetes mellitus (T2DM), 14 T2DM patients who underwent kidney transplantation, and 47 healthy volunteers. We provide evidence that heparanase levels in the urine of T2DM patients are markedly elevated compared to healthy controls (1162 ± 181 vs. 156 ± 29.6 pg/ml for T2DM and healthy controls, respectively), increase that is statistically highly significant (P<0.0001). Notably, heparanase levels were appreciably decreased in the urine of T2DM patients who underwent kidney transplantation, albeit remained still higher than healthy individuals (P<0.0001). Increased heparanase levels were also found in the plasma of T2DM patients. Importantly, urine heparanase was associated with elevated blood glucose levels, implying that glucose mediates heparanase upregulation and secretion into the urine and blood. Utilizing an in vitro system, we show that insulin stimulates heparanase secretion by kidney 293 cells, and even higher secretion is observed when insulin is added to cells maintained under high glucose conditions. These results provide evidence for a significant involvement of heparanase in diabetic complications.     

A randomized non-inferiority study comparing the addition of exenatide twice daily to sitagliptin or switching from sitagliptin to exenatide twice daily in patients with Type 2 diabetes experiencing inadequate glycaemic control on metformin and sitagliptin

Aims To test the hypothesis that glycaemic control achieved when switching sitagliptin to exenatide twice daily plus metformin is non-inferior to adding exenatide twice daily to sitagliptin and metformin. Methods Patients with Type?2 diabetes inadequately controlled with sitagliptin plus metformin were randomly assigned to 20?weeks of treatment with twice-daily exenatide plus placebo and metformin (SWITCH, n?=?127) or twice-daily exenatide plus sitagliptin and metformin (ADD, n?=?128). Results Non-inferiority (0.4% margin) of SWITCH to ADD treatment, measured by change in HbA(1c) from baseline to week?20, was not shown {between-treatment difference in least-squares mean [95%?CI 3?mmol/mol (0.30%)] [0.8-5.8 (0.07-0.53)]}. A greater reduction (P?=?0.012) in HbA(1c) [least-squares mean (se)] was experienced by patients in the ADD group {-7?mmol/mol [-0.68%] [0.9 (0.08)]}, compared with those in the SWITCH group {-4?mmol/mol [-0.38%] [1.0 (0.09)]} and a greater proportion (P?=?0.027) of patients in the ADD group (41.7%) reached 相似文献
