Background: Modern insulin pump therapy for type 1 diabetes mellitus offers the freedom to program several basal profiles that may accommodate diurnal variability in insulin sensitivity and activity level. However, these basal profiles do not change even if a pending hypoglycemic or hyperglycemic event is foreseen. New insulin pumps could receive a direct feed of glucose values from a continuous glucose monitoring (CGM) system and could enable dynamic basal adaptation to improve glycemic control. Method: The proposed method is a two-step procedure. After the design of an initial basal profile, an adaptation of the basal rate is suggested as a gain multiplier based on the current CGM glucose value and its rate of change (ROC). Taking the glucose value and its ROC as axes, a two-dimensional plane is divided into a nine-zone mosaic, where each zone is given a predefined basal multiplier; for example, a basal multiplier of zero indicates a recommendation to shut off the pump. Results: The proposed therapy was evaluated on 20 in silico subjects (ten adults and ten adolescents) in the Food and Drug Administration-approved UVa/Padova simulator. Compared with conventional basal therapy, the proposed basal adjustment improved the percentage of glucose levels that stayed in the range of 60–180 mg/dl for all 20 subjects. In addition, the adaptive basal therapy reduced the average blood glucose index values. Conclusions: The proposed therapy provides the flexibility to account for insulin sensitivity variations that may result from stress and/or physical activities. Because of its simplicity, the proposed method could be embedded in a chip in a future artificial pancreatic β cell or used in a “smart” insulin pump.

Glucose Lowering Therapy

The problems of complications of diabetes mellitus cannot be solved without constant monitoring of blood glucose levels. The evolution of additional technologies for the determination of glucose in the blood of the last decades makes it possible to more accurately predict the risks of complications, both in the individual and in the patient population as a whole. The article provides an overview of the methods used in modern diabetology, facilitating control over the variability of blood glucose levels and helping in a more accurate selection of glucose-lowering therapy. All presented methods are currently working in real clinical practice in the Khabarovsk Krai

The Impact

Development of truly useful wearable physiologic monitoring devices for use in diabetes management is still in its infancy. From wearable activity monitors such as fitness trackers and smart watches to contact lenses measuring glucose levels in tears, we are just at the threshold of their coming use in medicine. Ultimately, such devices could help to improve the performance of sense-and-respond insulin pumps, illuminate the impact of physical activity on blood glucose levels, and improve patient safety. This is a summary of our experience attempting to use such devices to enhance continuous glucose monitoring–augmented insulin pump therapy. We discuss the current status and present difficulties with available devices, and review the potential for future use.

The primary objective of the present study was to analyse the advantages of insulin pump therapy and real time glucose monitoring systems as the tools for reducing the frequency of hypoglycemic episodes. The study included 190 children and adolescents at the age varying from 1 to 18 years suffering from type 1 diabetes mellitus. All the patients were hospitalized at the Endocrinological Research Centre for the treatment the disease using different modalities of insulin therapy, such as multiple injections of insulin (MII) and its continuous subcutaneous infusion (CSII). The blood glucose level was monitored during 72 hours making use of the continuous blind and real time monitoring protocols (blind-CGM and RT-CGM respectively). All the patients were divided into 4 groups depending on the therapeutic modality and the mode of blood glucose monitoring. Group 1 was comprised of the patients given multiple insulin injections in combination with blind glucose monitoring ("blind-CGM + MII"), group 2 included the patients undergoing blind glucose monitoring in conjunction with continuous insulin infusion ("blind-CGM + CSII"), group 3 contained the patients treated by multiple insulin injections followed by real-time blood glucose monitoring ("RT-CGM + MII"), and group 4 was composed of the patients undergoing continuous subcutaneous infusion of insulin combined with real-time blood glucose monitoring ("RT-CGM + CSII"). In all the cases, the blood glucose levels were measured and the occurrence of hypoglycemia during the period of monitoring time was evaluated. It was shown that the highest frequency of hypoglycemia during 72 hours was recorded in the "blind-CGM" group and the lowest one in the RT-CGM groups. Despite adequate self-control, almost half of the patients in the "blind-CGM + MII" group reported at least one hypoglycemic episode either at the daytime or at night ; the duration of such episode was more than 1 hour on the average. In the "blind-CGM" group, CSII resulted in the decrease of the number of hypoglycemic episodes both at night and daytime (p<0.05). In the "RT-CGM + CSII" group, continuous insulin infusion reduced the mean duration of nocturnal hypoglycemic episodes (p<0.05) whereas this parameter was not significantly different between the other groups. It is concluded that hypoglycemia especially nocturnal one is rather a common problem facing children and adolescents suffering from type 1 diabetes mellitus. The use of insulin pump therapy and real time glucose monitoring systems (RT-CGM) makes it possible to substantially decrease the frequency and duration of hypoglycemic episodes in this population group.

Introduction. Diabetes mellitus (DM) is a highly prevalent disease worldwide. It has been associated with an important morbimortality due to its complications and sometimes as a result of adverse events related to treatment. Insulin pump therapy (IPT) is one of the options used to control this disease and reduces one of the most frequent complication associated with treatment: hypoglycemia, which has also a great impact on life quality and clinical status of patients. Materials and Methods. A descriptive and retrospective study was performed including patients treated and followed by the department of endocrinology from a high-complexity university hospital in Cali, Colombia, between 2012 and 2017. Patients were on IPT and continuous glucose monitoring (CGM): MiniMed Paradigm® Veo™ Insulin Pump (Medtronic®) and MiniMed 640G Insulin Pump-Enlite™ Sensor (Medtronic®). Presentation of hypoglycemia and variables associated with its development were evaluated. Results. 51 patients were included. The main indication for IPT initiation was the report of hypoglycemic episodes and inappropriate metabolic control. Initiation of IPT was related with a decrease in glycosylated hemoglobin (HbA1c) and also a decrease in severe hypoglycemic events and hospitalization due to hypoglycemia. The risk factors linked with clinically significant hypoglycemia were male gender, and standard deviation of glucose measures calculated by CGM. A diminished glomerular filtration rate (GFR) (<60 mL/min/1.73 m2) was correlated with higher risk of severe hypoglycemia. Conclusion. IPT with CGM is a useful strategy in the management of patients with DM; it is associated with a reduction of adverse hypoglycemic events and hospitalizations due to hypoglycemia.
