Factors related to glycemic control in IDDM and insulin-treated NIDDM patients in current practice. A comparison of care policies. SIEMTIC Group. Studio Italiano Epidemiologico Multicentrico su Terapia Insulin e Controllo Metabolico.

OBJECTIVE: To evaluate, under routine conditions, the relation between different diabetes care policies and glycemic control through a by-center analysis procedure aimed at reducing some drawbacks of cross-sectional data. RESEARCH DESIGN AND METHODS: A survey on insulin-treated diabetes care management (IDDM and NIDDM) involved 16 Italian randomly selected diabetes outpatient clinics. A total of 2,142 representative patients were investigated. The standardized HbA1c average value of each center was related, by regression models, to some indicators of center care policy (average number of injections, average BMI, proportion of cases with recent fundus oculi examinations, or frequent visits) as well as to patients' average social levels (employment type). Homogeneity in patient admission criteria is assumed among the investigated centers as a basic condition for the procedure validity. Some known imbalance were controlled for both design and analysis. RESULTS: HbA1c showed a univariate inverse relation with daily number of injections in IDDM (P = 0.0009, r2 = 0.56) but not in NIDDM (P = 0.33). It was inversely related to both fundus examination (IDDM P = 0.04; NIDDM P = 0.099) and qualified employment (IDDM P = 0.06; NIDDM P = 0.026). A stepwise regression analysis left in the model insulin injections (P = 0.0002) in IDDM (total r2 = 0.68) and qualified employment (P = 0.016) and fundus examination (P = 0.14) in NIDDM (total r2 = 0.53), after controlling for age, sex, disease duration, insulin therapy starting delay, and insulin dose per kilogram. CONCLUSIONS: These results suggest that the confirmed benefits of a multiple-injection regimen in IDDM cannot be simply extrapolated to NIDDM, where patients' awareness and medical attention to complications proved to be the most important factors in current practice.

Effects of dietary fiber supplementation on glycemic control in dogs with alloxan-induced diabetes mellitus.

The effect of a high insoluble-fiber (IF) diet containing 15% cellulose in dry matter, high soluble-fiber (SF) diet containing 15% pectin in dry matter, and low-fiber (LF) diet on glycemic control in 6 dogs with alloxan-induced insulin-dependent diabetes mellitus was evaluated. Each diet contained greater than 50% digestible carbohydrate in dry matter. A crossover study was used with each dog randomly assigned to a predetermined diet sequence. Each dog was fed each diet for 56 days. Caloric intake was adjusted weekly as needed to maintain each dog within 1.5 kg of its body weight measured prior to induction of diabetes mellitus. All dogs were given pork lente insulin and half of their daily caloric intake at 12-hour intervals. Mean (+/- SEM) daily caloric intake was significantly (P less than 0.05) less when dogs consumed the IF diet vs the SF and LF diets (66 +/- 3 kcal/kg, 81 +/- 5 kcal/kg, and 79 +/- 4 kcal/kg, respectively). Serum alkaline phosphatase activity was significantly (P less than 0.05) higher when dogs consumed the LF diet vs the IF and SF diets (182 +/- 37 IU/L, 131 +/- 24 IU/L, and 143 +/- 24 IU/L, respectively). Mean postprandial plasma glucose concentration measured every 2 hours for 24 hours, beginning at the time of the morning insulin injection, was significantly (P less than 0.05) lower at most blood sampling times in dogs fed IF and SF diets, compared with dogs fed the LF diet.(ABSTRACT TRUNCATED AT 250 WORDS)

Achieving glycemic control in type 2 diabetes: a practical guide for clinicians on oral hypoglycemics.

Type 2 diabetes mellitus has reached epidemic proportions in the United States. Cardiovascular morbidity and mortality are particularly high in this patient population. Improved glucose control, especially early in the course of diabetes, can slow or prevent complications, preserve beta-cell function, and improve long-term outcomes. Within the last decade, new treatments and glycemic goals have created an opportunity to better manage this prevalent, chronic disease. Defects of insulin resistance and deficiency leading to type 2 diabetes can now be directly targeted with available therapies. In addition to diet and exercise, oral treatment options have been broadened, with both insulin secretagogues and insulin sensitizers. These advances in treatment options make glycemic control an obtainable target, and therefore should improve overall morbidity and mortality for patients. This paper will review currently available oral therapies, with a focus on the unique attributes of the insulin sensitizers for patients with type 2 diabetes.

Rush University guidelines and protocols for the management of hyperglycemia in hospitalized patients: elimination of the sliding scale and improvement of glycemic control throughout the hospital.

The management of inpatient hyperglycemia has received much recent attention because of an expanding literature supporting the benefits of quality improvement and the creation of guidelines in this area. The authors began a process in 2002 to create modern protocols for glycemic control with intravenous insulin in their intensive care units and with subcutaneous basal-prandial insulin in all of their non-intensive care units. In this report, they describe both the process employed and the current protocols they are using. They also describe the process, perpetually ongoing, for educating nurses and residents in a large academic medical center. The annual cycle of senior residents passing on the regular insulin sliding scale to first-year interns and students can be broken. The hospital ward can be a valuable setting in which to teach basal/prandial insulin protocols, which will readily translate into the outpatient clinic. Where better to teach the importance and real-time usefulness of HbA1c than on the inpatient ward of a teaching hospital? Protocols to prevent and treat hypoglycemia can also be taught and widely accepted, hospital insulin formularies can be streamlined, and modern information technology can be used to track and improve multiple metrics of care for inpatients with hyperglycemia. The inpatient encounter with diabetic care can be a golden window of opportunity for patient as well as physician and nurse education.

Role of oxidative stress in the etiology of type 2 diabetes and the effect of antioxidant supplementation on glycemic control.

Oxidative stress is a situation in which the amount of reactive oxygen species (ROS) exceeds the levels of neutralizing substances referred to as antioxidants. Numerous studies have shown that oxidative stress is associated with type 2 diabetes, and there is compelling biochemical evidence that suggests that ROS may even play a role, if only secondary, in the pathogenesis of type 2 diabetes. These observations have provided sufficient impetus for the use of antioxidant supplements as adjunct therapy for control of blood sugar in diabetic patients. However, there is currently no optimum regimen of antioxidant supplementation for diabetic patients. Studies are required to determine appropriate doses of relevant individual micronutrients that perhaps should be used in combination to diminish oxidative stress and improve glycemic control in individuals afflicted with type 2 diabetes.

Clinical value of glycated hemoglobin and fructosamine in the long-term glycemic control of children with acute lymphoblastic leukemia.

Hyperglycemia in children with acute lymphoblastic leukemia (ALL) has been well documented in the literature. The purpose of the present study was to evaluate the clinical value of glycated hemoglobin (GHb) and fructosamine (Frc) in the long-term glycemic control of ALL patients. An attempt was made to identify the risk factors for hyperglycemia in ALL patients. The study group comprised 26 newly diagnosed ALL patients admitted to hospital during 1995-96. Patients with a history of blood transfusion or infection within the past 3 months were excluded from the study. White blood cell (WBC) counts, fasting blood glucose (FBG), GHb and Frc levels were analyzed in venous blood on screening day 0, before induction of chemotherapy. Frc analysis was repeated on the 21st day and GHb level on the 60th day of chemotherapy. FBG tests were performed before each dose of L-asparaginase, on days 21 and 60. None of the patients was obese. Although six children (23%) had hyperglycemia during the induction therapy, four of them had a GHb level higher than normal on admission. Only one patient who developed hyperglycemia had a family history of diabetes mellitus. Patients with a high initial WBC count (> 20 x 10(9)/L) had a significantly higher baseline GHb than patients with a WBC count below this level. GHb values returned to normal after achievement of complete remission. It is suggested that the leukemic process could impair glucose metabolism and baseline GHb may be used to monitor possible small changes in glucose homeostasis of ALL patients, prior to chemotherapy.

Financial implications of glycemic control: results of an inpatient diabetes management program.

OBJECTIVE: (1) To determine the financial implications associated with changes in clinical outcomes resulting from implementation of an inpatient diabetes management program and (2) to describe the strategies involved in the formation of this program. METHODS: The various factors that influence financial outcomes are examined, and previous and current outcomes are compared. RESULTS: Associations exist between hyperglycemia, length of stay, and hospital costs. Implementation of an inpatient diabetes management program, based on published guidelines, has been shown to increase the use of scheduled medications to treat hyperglycemia and increase the frequency of physician intervention for glucose readings outside desired ranges. Results from implementing this program have included a reduction in the average glucose level in the medical intensive care unit through use of protocols driven to initiate intravenous insulin once the glucose level exceeds 140 mg/dL. Additionally, glucose levels have been reduced throughout the hospital, primarily because of interactions between diabetes nurse care managers and the primary care team. Associated with these lower glucose levels are a decreased prevalence of central line infections and shorter lengths of stay. The reduction in the length of stay for patients with diabetes has resulted in a savings of more than 2 million dollars for the year and has yielded a 467% return on investment for the hospital. CONCLUSION: Improved blood glucose control during the hospitalization of patients with known hyperglycemia is associated with reduced morbidity, reduced hospital length of stay, and cost savings. The implementation of an inpatient diabetes management program can provide better glycemic control, thereby improving outcomes for hyperglycemic patients while saving the hospital money.

Effect of life-style activity of varying duration on glycemic control in type II diabetic women.

Life-style activities such as walking are often recommended for patients with type II (non-insulin-dependent) diabetes. Because many of these patients are overweight and sedentary, such low-intensity activity would appear most appropriate, especially during initial intervention. However, there has been little research on the effects of low-intensity life-style activity on glycemic control. This study examined the effects of varying the duration (0, 20, or 40 min) of low-intensity exercise (50-55% of age-predicted max heart rate) on glycemic responses during exercise and a subsequent meal in type II diabetic patients. Glycemic response to exercise was significantly related to the duration of activity; 20 min of activity decreased blood glucose (BG) by 6 mg/dl, whereas 40 min decreased BG by 16 mg/dl. The effect of exercise on glucose was maintained over a 30-min rest period but disappeared after a meal was consumed. Insulin and the insulin-to-glucose ratio were not affected by the length of activity. These data suggest that life-style activity of long duration (20-40 min) produces a significant, but modest, decrease in glucose levels in type II diabetic women.

Glycemic control and coronary heart disease risk in persons with and without diabetes: the atherosclerosis risk in communities study.

BACKGROUND: Chronic hyperglycemia has been hypothesized to contribute to coronary heart disease (CHD), but the extent to which hemoglobin A(1c) (HbA(1c)) level, a marker of long-term glycemic control, is independently related to CHD risk is uncertain. METHODS: We conducted a prospective case-cohort study of 1321 adults without diabetes and a cohort study of 1626 adults with diabetes from the Atherosclerosis Risk in Communities Study. Using proportional hazards models, we assessed the relation between HbA(1c) level and incident CHD during 8 to 10 years of follow-up. RESULTS: In adults with diabetes, the relative risk (RR) of CHD was 2.37 (95% confidence interval [CI], 1.50-3.72) for the highest quintile of HbA(1c) level compared with the lowest after adjustment for CHD risk factors. In persons without diabetes, the adjusted RR of CHD in the highest quintile of HbA(1c) level was 1.41 (95% CI, 0.90-2.30); however, there was evidence of a nonlinear relationship in this group. In nondiabetic adults, HbA(1c) level was not related to CHD risk below a level of 4.6% but was significantly related to risk above that level (P<.001). In diabetic adults, the risk of CHD increased throughout the range of HbA(1c) levels. In the adjusted model, the RR of CHD for a 1-percentage point increase in HbA(1c) level was 2.36 (95% CI, 1.43-3.90) in persons without diabetes but with an HbA(1c) level greater than 4.6%. In diabetic adults, the RR was 1.14 (95% CI, 1.07-1.21) per 1-percentage point increase in HbA(1c) across the full range of HbA(1c) values. CONCLUSION: Elevated HbA(1c) level is an independent risk factor for CHD in persons with and without diabetes.

Relationship of patient request fulfillment to compliance, glycemic control, and other health care outcomes in insulin-dependent diabetes.

Patients' perceptions of the extent to which their health care needs have been met may affect compliance with prescribed health behaviors and related health outcomes. The authors examined the relationships of "patient request fulfillment" to patient compliance, glycemic control, and several other health care outcomes in 51 adult outpatients with insulin-dependent diabetes mellitus. On average, patients retrospectively cited 4.5 long-term requests, of which over three-fourths were fulfilled. Fulfillment of these requests was significantly associated with patient satisfaction, perceived health status, fewer insulin reactions, and greater insulin injection time reliability (p less than 0.05), but not with several other measures of compliance. Higher patient request fulfillment at single visits was correlated, as hypothesized, with subsequent reduction in glycosylated hemoglobin, but this association was not statistically significant. These results suggest that patient request fulfillment is associated with several aspects of health behavior and health status in adults with insulin-dependent diabetes. Further studies are needed to confirm these observations and determine whether strategies to enhance patient request fulfillment can enhance health care outcomes.

Glycemic control and serum lipoproteins after total pancreatectomy.

Carbohydrate and lipid metabolism were studied in 10 patients who had undergone total pancreatectomy. The results were compared with Type I diabetic patients and normal subjects, all of whom were matched for age, sex and weight. At the same level of glycemic control, the daily need for insulin was significantly lower in the patients with pancreatogenic diabetes than in those with Type I diabetes. Concentrations of serum total VLDL and HDL triglyceride were higher in the pancreatectomized patients than in the diabetic or normal controls, whereas concentrations of serum total and LDL cholesterol were significantly lower. The composition of the VLDL, LDL and HDL particles was abnormal in the totally pancreatectomized patients as all three lipoprotein fractions were enriched in triglyceride. HDL2 cholesterol was similar in the totally pancreatectomized patients to that in the other two groups but HDL3 cholesterol was lower. Postheparin plasma lipoprotein lipase and hepatic lipase activities were normal. It is concluded that in totally pancreatectomized patients the changes in the lipoprotein profile on reflect more the action of various confounding factors, i.e. malabsorption, continuance of alcohol abuse and dietary changes than the impact of the diabetes itself.

Fructosamine and glycated hemoglobin as indices of glycemic control in patients with liver cirrhosis.

Glucose intolerance often occurs in liver cirrhosis; therefore a long-term control of plasma glucose levels appears to be important. For this purpose glycated hemoglobin A (HbA1c) determination is proposed as a suitable method, while no data are available on fructosamine test. In 98 cirrhotic patients serum fructosamine and HbA1c levels were compared with those of normal controls and among cirrhotic patients grouped in non glucose-intolerant and with non insulin-dependent (NIDDM) or insulin-dependent diabetes mellitus (IDDM). The mean HbA1c values of cirrhotic patients with normal glycemic control were significantly lower than normal, and only a few IDDM and NIDDM cirrhotic patients showed high values of HbA1c, indicating that HbA1c is often underestimated in these patients. On the contrary, serum fructosamine levels were on the average higher than normal in nondiabetic patients, but they were significantly higher in IDDM and NIDDM patients than in nondiabetics, and the 72% of NIDDM and 85% of IDDM patients had fructosamine levels higher than the upper normal value. In conclusion, in diabetic patients with liver cirrhosis fructosamine seems to be a more suitable test than HbA1c for monitoring blood glucose levels.

Erythrocyte aldose reductase protein: a clue to elucidate risk factors for diabetic neuropathies independent of glycemic control.

Prolonged hyperglycemia has been thought to be the primary cause of diabetic complications, however, some diabetic patients develop severe complications early in duration of diabetes, while some patients have no or mild complications even after prolonged hyperglycemia. To investigate the risk factors for diabetic severe neuropathy independent of glycemic control and duration of diabetes, erythrocyte aldose reductase was determined in 43 non-insulin-dependent diabetic patients by a two-site ELISA using recombinant human aldose reductase. Among 20 patients with severe neuropathy which was developed within 5 years of diagnosis, the level of erythrocyte aldose reductase protein was significantly higher than that of 23 patients with no or mild neuropathy who had more than 8 years duration of diabetes and prolonged hyperglycemia (11.9+/-5.7 vs. 8.3+/-1.3 ng/mgHb, P < 0.0001). There was a significant stability of the erythrocyte aldose reductase (AR) in the 40 diabetic patients during 1-4 years. The logistic regression analysis revealed that the maximum body mass index (BMI) in the past minus present BMI and the level of erythrocyte aldose reductase protein were the independent risk factors for diabetic severe neuropathy. The measurement of erythrocyte AR level may be useful for predicting severe neuropathy in non-insulin-dependent diabetes mellitus (NIDDM) patients.

Anthropometric parameters in infants of gestational diabetic women with strict glycemic control.

OBJECTIVE: Differences in weight and body composition have been reported between infants of nondiabetic and diabetic mothers. These differences may explain the propensity for shoulder dystocia in the diabetic population. We investigated whether differences in anthropometric measurements still exist between infants of nondiabetic and diabetic mothers following strict glycemic control. METHODS: This was a prospective cohort study. The study group included infants of well-controlled gestational diabetic mothers (mean capillary glucose less than 100 mg/dL). Controls were infants of nondiabetic mothers matched for gender, gestational age, ethnicity, and birth weight. Only singleton term pregnancies were included. Both groups were studied within 24 hours of delivery. The following measurements were obtained: birth weight, infant length, femur length, head, chest, abdomen and thigh circumferences, and biacromial distance. Student t tests were used to compare the measured parameters between groups. P < .05 was considered significant. A sample size of 63 subjects in each group was needed to demonstrate a difference of 0.5 cm (+/- 1.0 cm) of the biacromial distance between the 2 groups, which we considered clinically significant, with a probability of 95% and power of 80%. RESULTS: Sixty seven infants in each group were included in the study. Anthropometric measurements did not differ significantly between the groups. We did a secondary analysis on neonates who weighed 4,000 g or more at birth. Anthropometric measurements again did not differ significantly between the groups. CONCLUSION: Anthropometric measurements of infants of mothers with well-controlled gestational diabetes do not differ from infants of nondiabetic mothers. LEVEL OF EVIDENCE: II-2.

A kinetic mass balance model for 1,5-anhydroglucitol: applications to monitoring of glycemic control.

The polyol 1,5-anhydroglucitol (AG) present in human plasma is derived largely from ingestion and is excreted unmetabolized. Reduction of plasma [AG] has been noted in diabetics and is due to accelerated excretion of AG during hyperglycemia. Plasma [AG] has therefore been proposed as a marker for glycemic control. A precise understanding of its utility relies on a quantitative understanding of the mass balance for AG. In this study, non-steady-state data from the literature were analyzed to develop a dynamic mass balance model for AG that is based on the two-compartment model proposed by Yamanouchi et al. [T. Yamanouchi, Y. Tachibana, H. Akanuma, S. Minoda, T. Shinohara, H. Moromizato, H. Miyashita, and I. Akaoka. Am. J. Physiol. 263 (Endocrinol. Metab. 26): E268-E273, 1992]. The data are consistent with a model in which exchange between tissue and plasma pools is rapid and in which the tissue compartment mass is two to three times the mass of the plasma compartment. According to model estimates, accelerated excretion of AG due to hyperglycemia can cause marked net depletion of total AG over a time scale of days. Recovery from a depleted state is slow because the total body capacity represents >5 wk of normal intake. Accordingly, AG monitoring should be able to indicate the presence of past glucosuric hyperglycemic episodes during a period of days to weeks, as well as provide information on the extent to which high deviations from the average plasma glucose concentration are operative.

Effects of glycemic control and other determinants on vascular disease in type 2 diabetes.

Cardiovascular disease is the leading cause of death in patients with type 2 diabetes, with more than 77,000 deaths each year. The risk remains high despite normalization of well-known cardiovascular risk factors, and the impact of glycemic control on risk reduction remains controversial. Deleterious changes in fibrinolysis, platelet function, and coagulation secondary to insulin resistance and/or the metabolic derangements of type 2 diabetes have emerged as likely mechanisms underlying increased cardiovascular risk. Plasminogen activator inhibitor-1 (PAI-1) is an inhibitor of the fibrinolytic system. Thus, elevated concentrations of PAI-1 promote persistence of clots. Concentrations of PAI-1 are elevated in the blood and vessel walls of patients with type 2 diabetes or other insulin-resistant states. We have hypothesized that increased PAI-1 can create conditions favorable to the evolution of unstable, lipid-laden atherosclerotic coronary plaques, thereby rendering patients with diabetes highly susceptible to rupture of vulnerable plaques and acute coronary syndromes. Therapeutic interventions that may alter this evolution by reducing concentrations of PAI-1 or correct metabolic derangements that promote it are being studied. Antiplatelet therapy has been directed at the increased platelet reactivity characteristic of patients with diabetes. Its use has reduced complications after percutaneous coronary intervention following the onset of unstable angina. Amelioration of diabetic cardiomyopathy by correction of impaired myocardial energy metabolism and limiting the accumulation of advanced glycation end products is being evaluated as well.

Walking behaviour and glycemic control in type 2 diabetes: seasonal and gender differences--study design and methods.

BACKGROUND: The high glucose levels typically occurring among adults with type 2 diabetes contribute to blood vessel injury and complications such as blindness, kidney failure, heart disease, and stroke. Higher physical activity levels are associated with improved glycemic control, as measured by hemoglobin A1C. A 1% absolute increase in A1C is associated with an 18% increased risk for heart disease or stroke. Among Canadians with type 2 diabetes, we postulate that declines in walking associated with colder temperatures and inclement weather may contribute to annual post-winter increases in A1C levels. METHODS: During this prospective cohort study being conducted in Montreal, Quebec, Canada, 100 men and 100 women with type 2 diabetes will undergo four assessments (once per season) over a one-year period of observation. These assessments include (1) use of a pedometer with a concealed viewing window for a two-week period to measure walking (2) a study centre visit during which venous blood is sampled for A1C, anthropometrics are assessed, and questionnaires are completed for measurement of other factors that may influence walking and/or A1C (e.g. food frequency, depressive symptomology, medications). The relationship between spring-fall A1C difference and winter-summer difference in steps/day will be examined through multivariate linear regression models adjusted for possible confounding. Interpretation of findings by researchers in conjunction with potential knowledge "users" (e.g. health professionals, patient groups) will guide knowledge translation efforts. DISCUSSION: Although we cannot alter weather patterns to favour active lifestyles, we can design treatment strategies that take seasonal and weather-related variations into account. For example, demonstration of seasonal variation of A1C levels among Canadian men and women with T2D and greater understanding of its determinants could lead to (1) targeting physical activity levels to remain at or exceed peak values achieved during more favourable weather conditions. Strategies may include shifting to indoor activities or adapting to less favourable conditions (e.g. appropriate outdoor garments, more frequent but shorter duration periods of activity) (2) increasing dose/number of glucose-lowering medications during the winter and reducing these during the summer, in anticipation of seasonal variations (3) examining the impact of bright light therapy on activity and A1C among T2D patients with an increase in depressive symptomology when sunlight hours decline.

Fish oil and glycemic control in diabetes. A meta-analysis.

OBJECTIVE: Hypertriglyceridemia is associated with cardiovascular disease in diabetes. Fibrates effectively lower, but do not always normalize, serum triglyceride levels. Fish oil supplements may then be added to lower serum triglyceride levels. Doubt remains whether the net effect of fish oil intake on glycemic control is beneficial in diabetes. We therefore performed a meta-analysis from published clinical trials. RESEARCH DESIGN AND METHODS: Data sources were Medline (Cologne, Germany), Excerpta Medica, Current Contents, review articles, and published reference lists. Publications of 26 trials were selected, and all trials included more than five diabetes (IDDM and NIDDM) patients and addressed the effects of fish oil (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) on serum lipids and glucose tolerance. We (C.E.F., M.J.F.M.J.) extracted data independently based on predetermined criteria. Studies were classified according to design. RESULTS: All studies combined showed a decrease in mean triglyceride concentrations in association with fish oil: -0.60 mmol/l (95% CI, -0.84 to -0.33, P < 0.01) and a slight but significant increase in serum LDL cholesterol: 0.18 mmol/l (95% CI, 0.04-0.32, P = 0.01), with both findings most prominent in NIDDM. No significant changes in HbA1c percentages occurred in diabetic subjects treated with fish oil. Fasting blood glucose levels were increased with borderline significance in NIDDM subjects (0.43 mmol/l [95% CI, 0.00-0.87], P = 0.06) and were significantly lower in IDDM subjects (-1.86 mmol/l [95% CI, -3.1 to -0.61], P < 0.05). Significant dose-response effects of EPA (g/day) on HbA1c and triglycerides and of DHA (g/day) on fasting blood glucose levels, HbA1c, and triglycerides were demonstrated only in NIDDM subjects. CONCLUSIONS: The use of fish oil has no adverse affects on HbA1c in diabetic subjects and lowers triglyceride levels effectively by almost 30%. However, this may be accompanied by a slight increase in LDL cholesterol concentration. Fish oil may be useful in treating dyslipidemia in diabetes.
