Hybrid Closed-Loop Systems for the Treatment of Type 1 Diabetes: A Collaborative, Expert Group Position Statement for Clinical Use in Central and Eastern Europe. Diabetes Ther 2021; 12:3107-3135. [PMID: 34694585 PMCID: PMC8586062 DOI: 10.1007/s13300-021-01160-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Accepted: 09/18/2021] [Indexed: 01/23/2023] Open
Abstract
In both pediatric and adult populations with type 1 diabetes (T1D), technologies such as continuous subcutaneous insulin infusion (CSII), continuous glucose monitoring (CGM), or sensor-augmented pumps (SAP) can consistently improve glycemic control [measured as glycated hemoglobin (HbA1c) and time in range (TIR)] while reducing the risk of hypoglycemia. Use of technologies can thereby improve quality of life and reduce the burden of diabetes management compared with self-injection of multiple daily insulin doses (MDI). Novel hybrid closed-loop (HCL) systems represent the latest treatment modality for T1D, combining modern glucose sensors and insulin pumps with a linked control algorithm to offer automated insulin delivery in response to blood glucose levels and trends. HCL systems have been associated with increased TIR, improved HbA1c, and fewer hypoglycemic events compared with CSII, SAP, and MDI, thereby potentially improving quality of life for people with diabetes (PwD) while reducing the costs of treating short- and long-term diabetes-related complications. However, many barriers to their use and regional inequalities remain in Central and Eastern Europe (CEE). Published data suggest that access to diabetes technologies is hindered by lack of funding, underdeveloped health technology assessment (HTA) bodies and guidelines, unfamiliarity with novel therapies, and inadequacies in healthcare system capacities. To optimize the use of diabetes technologies in CEE, an international meeting comprising experts in the field of diabetes was held to map the current regional access, to present the current national reimbursement guidelines, and to recommend solutions to overcome uptake barriers. Recommendations included regional and national development of HTA bodies, efficient allocation of resources, and structured education programs for healthcare professionals and PwD. The responsibility of the healthcare community to ensure that all individuals with T1D gain access to modern technologies in a timely and economically responsible manner, thereby improving health outcomes, was emphasized, particularly for interventions that are cost-effective.

Abstract
Insulin (INS) therapy played a great role in patients with type 1 and type 2 diabetes to regulate
blood glucose levels. Although hypodermic injection was commonly used for insulin delivery, it
had some disadvantages such as pain, needle phobia and the risk of infection. Therefore, pulmonary
insulin delivery had been developed as an alternative method to overcome the therapeutic challenges in
recent years since pulmonary insulin administration showed great improvements in rapid action and
circumvention of first-pass hepatic metabolism. This review described the most recent developments in
pulmonary insulin administration. Firstly, the structure and physiology of the lung cavity were introduced.
Next, the advantages and disadvantages of pulmonary administration were discussed. Then
some new dosage forms for pulmonary insulin were investigated including carriers based on surfactants
and carriers based on polymers. Finally, innovate insulin inhalers and formulations were also described.

Abstract
AIMS To assess the efficacy of insulin pumps with automated insulin suspension systems in a real-world setting. METHODS We analysed anonymized data uploaded to CareLink™ by people (n=920) with Type 1 diabetes using the MiniMed Paradigm Veo system and the MiniMed 640G system (Medtronic International Trading Sàrl, Tolochanez, Switzerland) with SmartGuard technology, with or without automated insulin suspension enabled, between February 2016 and June 2018. Users with ≥15 days of sensor data and ≥70% sensor-wear time were classified as sensor-augmented pump alone, sensor-integrated pump with low glucose suspend enabled or sensor-integrated pump with predictive low glucose management enabled. RESULTS The median (25th -75th percentile) system use was 161 (58-348) days. The median time spent with sensor glucose values ≤3 mmol/l was 0.8 (0.3-1.7)% in the sensor-augmented pump group, 0.3 (0.1-0.7)% in the sensor-integrated pump with low glucose suspend group, and 0.3 (0.1-0.5)% in the sensor-integrated pump with predictive low glucose management group. In individuals switching from sensor-augmented pump to sensor-integrated pump with low glucose suspend (n=31), there were significant reductions in the monthly rate of hypoglycaemic events <3 mmol/l (rate ratio 0.63, 95% CI 0.45-0.89; P=0.009) and in the percentage of time with glucose values ≤3 mmol/l [sensor-augmented pump: 0.63% (95% CI 0.34-1.29), sensor-integrated pump with low glucose suspend: 0.33% (95% CI 0.16-0.64); P=0.001]. The monthly rate of hypoglycaemic events decreased further in individuals (n=139) switching from sensor-integrated pump with low glucose suspend to sensor-integrated pump with predictive low glucose management [rate ratio 0.82 (95% CI 0.69-0.98); P<0.0274]. Similar results were seen for events <3.9 mmol/l. There was no difference in median time spent in target glucose range. CONCLUSION Real-world UK data show that increasing automation of insulin suspension reduces hypoglycaemia exposure in people with Type 1 diabetes.

Abstract
BACKGROUND The Medtronic predictive low-glucose management (PLGM) algorithm automatically stops insulin delivery when sensor glucose (SG) is predicted to reach or fall below a preset low-glucose value within the next 30 min, and resumes delivery after hypoglycemia recovery. The present study evaluated the PLGM algorithm performance of the MiniMed™ 670G system SmartGuard™ "suspend before low" feature in children aged 7-13 years with type 1 diabetes (T1D). METHOD Participants (N = 105, mean ± standard deviation of 10.8 ± 1.8 years) underwent an overnight in-clinic evaluation of the "suspend before low" feature with a preset low limit of 65 mg/dL. After exercise, frequent sample testing (FST) was conducted every 5 min if values were <70 mg/dL; every 15 min if 70-80 mg/dL; and every 30 min if >80 mg/dL. First-day performance of the Guardian™ Sensor 3 glucose sensor and continuous glucose monitoring system was also evaluated. RESULTS Activation of the "suspend before low" feature occurred in 79 of the 105 participants, 79.7% (63/79) did not result in SG falling below 65 mg/dL. Mean glucose at activation was 102 ± 19 mg/dL and the initial insulin suspension duration was 87.5 ± 32.7 min. Four hours after insulin resumption, mean reference glucose was 130 ± 42 mg/dL. Mean absolute relative difference between the FST reference glucose and SG values on the first day of sensor wear was 11.4%. For the 26 participants in whom the "suspend before low" feature did not activate, none involved a reference glucose value ≤65 mg/dL, suggesting that the PLGM algorithm performed as intended. CONCLUSION In children aged 7-13 years with T1D, the "suspend before low" feature of the MiniMed 670G system demonstrated a hypoglycemia prevention rate of nearly 80% after exercise and did not involve rebound hyperglycemia. There were no events of severe hypoglycemia during the evaluation.

Abstract
BACKGROUND Sensor-integrated pump systems with low-glucose suspend (also known as threshold suspend) functions have markedly transformed the management of type 1 diabetes, but most studies to date have excluded patients at high risk of hypoglycemia. The SMILE study is investigating the efficacy of the MiniMed™ 640G insulin pump with the SmartGuard™ predictive low-glucose management (PLGM) feature in the prevention of hypoglycemia in adults with type 1 diabetes, who are at high risk of hypoglycemia. METHODS SMILE is a prospective, randomized, open-label, controlled trial being undertaken in four European countries and Canada. Following a 2-week run-in phase, eligible participants will be randomized to use either the MiniMed 640G system with continuous glucose monitoring (CGM) and the SmartGuard PLGM feature on continuously for 24 weeks (treatment arm), or the MiniMed 640G without CGM and with blinded continuous glucose measurements between weeks 10-12, 16-18, and 22-24 (control arm). The primary endpoint is the mean number of hypoglycemic events, defined as sensor glucose ≤55 mg/dL (≤3.0 mmol/L) for >20 consecutive minutes. Secondary endpoints include various glycemic indices in the hypoglycemic and hyperglycemic ranges, as well as glycated hemoglobin. Data on patient-reported outcomes such as hypoglycemia awareness and treatment satisfaction will also be collected. CONCLUSIONS It is anticipated that the SMILE study will provide important insights into the effectiveness of SmartGuard technology in adult patients with type 1 diabetes.
