    ABSTRACT: Background: Several studies have found improved glycemic control with continuous subcutaneous insulin infusion compared with multiple daily insulin injections for patients with type 1 diabetes, albeit for a relatively short-period of follow-up. This prospective study presents for the first time the optimization of glycemic control with insulin pumps in a cohort of Greek patients with type 1 diabetes for a 3-year follow-up period during the socioeconomic crisis in Greece. Materials and methods: Ninety-four patients, previously on intensified basal-bolus insulin therapy with poor glycemic control, were initially recruited. Glycosylated hemoglobin (HbA1c), hypoglycemic and diabetic ketoacidosis episodes, pump-related side effects, lipidemic profile, 24-h urine albumin excretion, body mass index, blood pressure, and total daily insulin requirements (bolus and basal) were recorded during the 3-year follow-up. Statistical analysis was initially conducted for the entire study population and after body mass index and gender stratification. Results: Seventy-nine patients completed the study. A statistically significant decrease of HbA1c level (P < 0.0001) was observed at the end of Year 1 and was retained for the following years for the whole population. Similarly, significantly fewer hypoglycemic episodes occurred during the follow-up period (P < 0.0001) compared with study entry. Insulin pump treatment was not accompanied with weight changes across all body mass index strata. Conclusions: Continuous subcutaneous insulin infusion achieved almost optimal glycemic control, reduced the number of hypoglycemic episodes without weight gain, and was well tolerated for the whole study period. Finally, this therapeutic approach was accompanied with lower daily insulin requirements.

    ABSTRACT: Background: A better understanding of parent and adolescent interest in using smartphone technology for type 1 diabetes (T1D) management is needed prior to developing technology-based interventions for ethnic minorities. This study examined access to and interest in technology-based programs for T1D in primarily Hispanic adolescents and their parents. Subjects and methods: During a scheduled clinic visit, adolescents with T1D (n = 50; 52% female; 13.6 ± 2.0 years old; 74% Hispanic; hemoglobin A1c = 8.9 ± 1.7%) and their parents (n = 49; 54% household income <$49,000) completed brief self-report surveys. Results: Adolescents reported having access to the Internet (98%) and their own smartphones (86%). Thirty-seven percent reported using smartphone applications (apps) for their diabetes care, with 88% reporting carbohydrate counting as its primary function. Although most participants reported high/moderate interest in diabetes-specific apps, girls were more likely than boys to endorse high interest in apps to calculate and track insulin doses. A greater proportion of parents than of adolescents expressed high interest in apps to track glucose, count carbohydrates, calculate insulin doses, track insulin use, and receive diabetes-related reminders. A greater proportion of parents than of adolescents also endorsed interest in a program that combined Internet use with smartphone apps. Conclusions: Results suggest ethnic minority adolescents with T1D across a range of income levels have access to smartphones. Although most parents expressed high interest in diabetes-specific apps, there was greater variability in adolescent interest. Understanding barriers and facilitators to the use of smartphone apps for diabetes care in ethnic minority adolescents may increase their interest in and ultimate adoption of this technology.

    ABSTRACT: Background: Insulin glargine 300 U/mL (Gla-300) has a more constant and prolonged action profile than insulin glargine 100 U/mL and in clinical studies is associated with similar glycemic control but less hypoglycemia. Whether its effects are altered by variability of injection time was examined in two 3-month substudies. Materials and methods: Eligible participants completing 6 months of optimized treatment with Gla-300 in EDITION 1 (n = 109) and EDITION 2 (n = 89), having a mean hemoglobin A1c (HbA1c) level of 7.3 % (SD 1.0 %), were randomized (1:1) to groups advised to increase variability of between-injection intervals to 24 ± up to 3 h or to maintain fixed 24-h intervals for 3 months. Changes of HbA1c level and other efficacy and safety measures were assessed. Results: In the fixed-dosing group, 64% of participants reported all intervals within the 23-25-h range, compared with 15% of those advised flexible dosing. In the fixed- and flexible-dosing groups, 12% and 41%, respectively, of between-injection intervals were outside the 23-25-h range, and 2% and 16%, respectively, were outside the 21-27-h range. Least squares mean between-group difference in HbA1c change from baseline was 0.05 % (95% confidence interval [CI], -0.13 to 0.23); for fasting plasma glucose, 2.7 mg/dL (95% CI, -9.0 to 14.4); and for daily basal insulin dose, 0.00 U/kg (95% CI, -0.02 to 0.03). Frequencies of hypoglycemia and adverse events did not differ between groups. Conclusions: The efficacy and safety of Gla-300 demonstrated in EDITION 1 and EDITION 2 are maintained in substudies when the insulin was injected up to 3 h before or after the usual time of administration.

    ABSTRACT: Background: The Food Insulin Index (FII) is a novel algorithm for ranking foods based on their insulin demand relative to an isoenergetic reference food. We compared the effect of carbohydrate counting (CC) versus the FII algorithm for estimating insulin dosage on glycemic control in type 1 diabetes. Materials and methods: In a randomized, controlled trial, adults (n = 26) using insulin pump therapy were assigned to using either traditional CC or the novel Food Insulin Demand (FID) counting for 12 weeks. Subjects participated in group education and individual sessions. At baseline and on completion of the trial, glycated hemoglobin A1c (HbA1c), day-long glycemia (6-day continuous glucose monitoring), fasting lipids, and C-reactive protein were determined. Results: Changes in HbA1c from baseline to 12 weeks were small and not significant in both groups (mean ± SEM; FII vs. CC, -0.1 ± 0.1% vs. -0.3 ± 0.2%; P = 0.855). The incremental area under the curve following breakfast declined significantly among the FID counters with no change in the CC group (FID vs. CC, -93 ± 41 mmol/L/min [P = 0.043] vs. 4 ± 50 mmol/L/min [P = 0.938]; between groups, P = 0.143). The mean amplitude of the glycemic excursion (MAGE) was significantly reduced among the FID counters (FID vs. CC, -6.1 ± 1.0 vs. -1.3 ± 1.0 mmol/L; P = 0.003), and only the FID counters experienced a trend (-44% vs. +11%; P = 0.057) to reduced hypoglycemia. Conclusions: In a 12-week pilot study, MAGE and postprandial glycemia following breakfast were significantly improved with FII counting versus CC, despite no significant differences in HbA1c.

    ABSTRACT: Background and Aim: Current literature regarding insulin pump-associated adverse events including pump malfunction, infusion set/site issues is discussed. We evaluated metabolic and non–metabolic adverse events in a large cohort of children and adolescents with type 1 diabetes (T1D), using insulin pump therapy. Methods: Data have been collected on patients younger than 19 years, starting insulin pump therapy before December 31st2013. For each patient age, disease duration, date of insulin pump therapy initiation, insulin pump model, breakdown/malfunction/pump replacement yes/no and reason, catheter/infusion set failures have been considered prospectively for the calendar year 2014. Results: Data have been returned by 20 pediatric Centers belonging to the Italian Diabetes Study Group about 916 T1D children and adolescents using insulin pump. During 2014, the most frequent infusion set and site problems were bubbles (38.2%), kinking (13%), leakage (10.3%), tunneling (10.2%), blockage (8.8%), bleeding (11%), lipohypertrophy (7.1%), infection (1.4%). Pump device has been replaced in 19.2% of patients: 82% for pump breakdown/malfunctions and 18% for ‘physiologic’ replacement after warranty. HbA1C mean value was 7.6% for the whole population. No relationship between pump replacement and HbA1C value was found. Only 1 DKA has been recorded due to pump failure. No severe hypoglycemia has been recorded due to pump or infusion set malfunction. Conclusions: Despite frequent infusion set problems, pump breakdown/malfunction and consequent replacement and metabolic adverse events in a large cohort of pediatric Italian patients with T1D are not as frequent as previously reported. Continuous educational programs are necessary for pump therapy management.

    ABSTRACT: Objective: This study was designed to evaluate accuracy, performance, and safety of the Dexcom (San Diego, CA) G4(®) Platinum continuous glucose monitoring (CGM) system (G4P) compared with the Dexcom G4 Platinum with Software 505 algorithm (SW505) when used as adjunctive management to blood glucose (BG) monitoring over a 7-day period in youth, 2-17 years of age, with diabetes. Research design and methods: Youth wore either one or two sensors placed on the abdomen or upper buttocks for 7 days, calibrating the device twice daily with a uniform BG meter. Participants had one in-clinic session on Day 1, 4, or 7, during which fingerstick BG measurements (self-monitoring of blood glucose [SMBG]) were obtained every 30 ± 5 min for comparison with CGM, and in youth 6-17 years of age, reference YSI glucose measurements were obtained from arterialized venous blood collected every 15 ± 5 min for comparison with CGM. The sensor was removed by the participant/family after 7 days. Results: In comparison of 2,922 temporally paired points of CGM with the reference YSI measurement for G4P and 2,262 paired points for SW505, the mean absolute relative difference (MARD) was 17% for G4P versus 10% for SW505 (P < 0.0001). In comparison of 16,318 temporally paired points of CGM with SMBG for G4P and 4,264 paired points for SW505, MARD was 15% for G4P versus 13% for SW505 (P < 0.0001). Similarly, error grid analyses indicated superior performance with SW505 compared with G4P in comparison of CGM with YSI and CGM with SMBG results, with greater percentages of SW505 results falling within error grid Zone A or the combined Zones A plus B. There were no serious adverse events or device-related serious adverse events for either the G4P or the SW505, and there was no sensor breakoff. Conclusions: The updated algorithm offers substantial improvements in accuracy and performance in pediatric patients with diabetes. Use of CGM with improved performance has potential to increase glucose time in range and improve glycemic outcomes for youth.

    ABSTRACT: Background: Efforts at improving quality metrics in diabetes focus on minimizing adverse events and avoiding re-admissions to the hospital. Our experience with Glucommander™ (Glytec, Greenville, SC), a cloud-based insulin management software system, suggested that its use in the emergency department (ED) would be useful in treating patients with mild diabetic ketoacidosis (DKA). Materials and methods: Thirty-five patients seen in the ED with hyperglycemic crises and diagnosed with DKA during one calendar year were reviewed. A retrospective chart review was performed on patients who were placed on Glucommander™ for DKA management. We excluded patients with significant acidosis or concomitant medical illnesses. Results: Initial average capillary glucose level was 487 ± 68 mg/dL, average time to target glucose was 5 h 11 min, and rate of hypoglycemia (blood glucose level <70 mg/dL) was less than 0.3%. Sixteen patients treated with the protocol were discharged from the ED directly, and 19 were admitted. Patients were maintained for an average of 14 ± 1 h on the Glucommander™ protocol. There was a significantly higher anion gap (P = 0.002) and lower serum bicarbonate level (P = 0.006) in the admitted group. We found very low evidence of re-admission (6%) within 30 days of discharge from the ED for DKA patients. No significant glucose-related adverse events were noted. Conclusions: Use of Glucommander™ for guiding the insulin treatment of mild DKA in the ED can decrease admissions to the hospital for DKA by 45%. Low rates of hypoglycemia make this an option to improve efficiency of utilization of inpatient hospital beds. The cost savings for nonadmissions were estimated at $78,000 over the 12 months of the study. Our results suggest that Glucommander™ is a safe and efficient tool for use in the ED to manage mild to moderate DKA.

    ABSTRACT: Continuous glucose monitoring (CGM) provides information unattainable by intermittent capillary blood glucose, including instantaneous real-time display of glucose level and rate of change of glucose, alerts and alarms for actual or impending hypo- and hyperglycemia, "24/7" coverage, and the ability to characterize glycemic variability. Progressively more accurate and precise, reasonably unobtrusive, small, comfortable, user-friendly devices connect to the Internet to share information and are sine qua non for a closed-loop artificial pancreas. CGM can inform, educate, motivate, and alert people with diabetes. CGM is medically indicated for patients with frequent, severe, or nocturnal hypoglycemia, especially in the presence of hypoglycemia unawareness. Surprisingly, despite tremendous advances, utilization of CGM has remained fairly limited to date. Barriers to use have included the following: (1) lack of Food and Drug Administration approval, to date, for insulin dosing ("nonadjuvant use") in the United States and for use in hospital and intensive care unit settings; (2) cost and variable reimbursement; (3) need for recalibrations; (4) periodic replacement of sensors; (5) day-to-day variability in glycemic patterns, which can limit the predictability of findings based on retrospective, masked "professional" use; (6) time, implicit costs, and inconvenience for uploading of data for retrospective analysis; (7) lack of fair and reasonable reimbursement for physician time; (8) inexperience and lack of training of physicians and other healthcare professionals regarding interpretation of CGM results; (9) lack of standardization of software methods for analysis of CGM data; and (10) need for professional medical organizations to develop and disseminate additional clinical practice guidelines regarding the role of CGM. Ongoing advances in technology and clinical research have addressed several of these barriers. Use of CGM in conjunction with an insulin pump with automated suspension of insulin infusion in response to actual observed or predicted hypoglycemia, as well as progressive refinement of closed-loop systems, is expected to dramatically enhance the clinical utility and utilization of CGM.

    ABSTRACT: Continuous glucose monitoring (CGM) has increased in popularity as a daily management tool for people with diabetes and a diagnostic instrument for their healthcare providers. Achieving better clinical outcomes hinges on appropriate analysis and interpretation of data collected by CGM systems. This includes device downloading, qualification of data, and generation of applicable reports. An objectives-based analysis of the reports can yield valuable insight for fine-tuning treatment in several areas, including postprandial glucose patterns, overnight/basal stability, duration of bolus insulin action, timing of (and response to) hypoglycemic episodes, the efficacy of meal and correction insulin doses, and the impact of a variety of lifestyle activities.

    ABSTRACT: Objective: This study was performed to understand and to compare differences in utilization of continuous glucose monitoring (CGM) and the rate of change (ROC) arrow to adjust insulin therapy among individuals with type 1 diabetes (T1D), comparing those treated with multiple daily insulin injections (MDI) with those treated with continuous subcutaneous insulin infusion (CSII). Research design and methods: We surveyed 222 T1D individuals who regularly used real-time CGM to obtain information about general CGM use and response to glucose ROC arrows in managing their diabetes. Results: The survey was completed by 222 T1D individuals. Respondents included CSII (n = 166) and MDI (n = 56) users. MDI and CSII respondents reported similar substantial increases in correction dosages (from 220 mg/dL to 120 mg/dL) in response to increasing glucose (one ROC arrow up: rising 2-3 mg/dL/min): +120% and +108%, respectively (P = 0.13). MDI and CSII respondents reported similar substantial increases in correction dosages in response to rapidly increasing glucose (two arrows up: rising >3 mg/dL/min): +146% and +138%, respectively (P = 0.72). When correcting from 220 mg/dL to 120 mg/dL, MDI respondents reported larger correction dosage reductions than CSII respondents in response to decreasing glucose (one ROC down arrow: decreasing 2-3 mg/dL/min) and rapidly decreasing glucose (two ROC down arrows: decreasing >3 mg/dL/min): -50% versus -37%, respectively (P = 0.024) and -52% versus 38%, respectively (P = 0.034). Similar between-group differences were observed in mealtime dosage adjustments. Conclusions: CGM users often rely on ROC information when determining insulin doses and tend to make larger changes than current recommendations suggest regardless of insulin delivery method.

    ABSTRACT: Background: Recent advances in accuracy and reliability of continuous glucose monitoring (CGM) devices have focused renewed interest on the use of such technology for therapeutic dosing of insulin without the need for independent confirmatory blood glucose meter measurements. An important issue that remains is the susceptibility of CGM devices to erroneous readings in the presence of common pharmacologic interferences. We report on a new method of assessing CGM sensor error to pharmacologic interferences using the example of oral administration of acetaminophen. Materials and methods: We examined the responses of several different Food and Drug Administration-approved and commercially available CGM systems (Dexcom [San Diego, CA] Seven(®) Plus™, Medtronic Diabetes [Northridge, CA] Guardian(®), and Dexcom G4(®) Platinum) to oral acetaminophen in 10 healthy volunteers without diabetes. Microdialysis catheters were placed in the abdominal subcutaneous tissue. Blood and microdialysate samples were collected periodically and analyzed for glucose and acetaminophen concentrations before and after oral ingestion of 1 g of acetaminophen. We compared the response of CGM sensors with the measured acetaminophen concentrations in the blood and interstitial fluid. Results: Although plasma glucose concentrations remained constant at approximately 90 mg/dL (approximately 5 mM) throughout the study, CGM glucose measurements varied between approximately 85 to 400 mg/dL (from approximately 5 to 22 mM) due to interference from the acetaminophen. The temporal profile of CGM interference followed acetaminophen concentrations measured in interstitial fluid (ISF). Conclusions: This is the first direct measurement of ISF concentrations of putative CGM interferences with simultaneous measurements of CGM performance in the presence of the interferences. The observed interference with glucose measurements in the tested CGM devices coincided temporally with appearance of acetaminophen in the ISF. The method applied here can be used to determine the susceptibility of current and future CGM systems to interference from acetaminophen or other exogenous pharmacologic agents.
