Abstract
In order to achieve optimal glycemic control, intensive insulin regimes are needed for individuals with Type 1 Diabetes (T1D) and insulin-dependent Type 2 Diabetes (T2D). Unfortunately, intensive glycemic control often results in insulin-induced hypoglycemia. Moreover, recurrent episodes of hypoglycemia result in both the loss of the characteristic warning symptoms associated with hypoglycemia and an attenuated counterregulatory hormone responses. The blunting of warning symptoms is known as impaired awareness of hypoglycemia (IAH). Together, IAH and the loss of the hormonal response is termed hypoglycemia associated autonomic failure (HAAF). IAH is prevalent in up to 25% in people with T1D and up to 10% in people with T2D. IAH and HAAF increase the risk of severe hypoglycemia 6-fold and 25-fold, respectively. To reduce this risk for severe hypoglycemia, multiple different therapeutic approaches are being explored that could improve awareness of hypoglycemia. Current therapies to improve awareness of hypoglycemia include patient education and psychoeducation, the use of novel glycemic control technology, pancreas/islet transplantation, and drug therapy. This review examines both existing therapies and potential therapies that are in pre-clinical testing. Novel treatments that improve awareness of hypoglycemia, via improving the counterregulatory hormone responses or improving hypoglycemic symptom recognition, would also shed light on the possible neurological mechanisms that lead to the development of IAH. To reduce the risk of severe hypoglycemia in people with diabetes, elucidating the mechanism behind IAH, as well as developing targeted therapies is currently an unmet need for those that suffer from IAH.

Abstract
Aim: To analyze the clinical effect of continuous subcutaneous insulin infusion (CSII) in type 1 diabetes mellitus (T1D) patients in the Spanish real-world scenario. Methods: All T1D patients on CSII registered in the SPAnish Insulin Pump (SPAIP) registry were included. The primary efficacy outcome was change in HbA1c during follow-up. Secondary efficacy outcomes included: insulin pump indications, diabetes complication rates, insulin and pump use, and continuous glucose monitoring (CGM) glycometrics. Patient data were typed through the web-based SPAIP registry. Results: Data from 2979 T1D patients treated with CSII were analyzed. The median age was 44 years (interquartile range [IQR] 34-52 years), and T1D duration was 27 years (IQR 18-35 years). The median duration of CSII therapy was 6 years (IQR 3-10 years). The main indications for treatment were suboptimal glycemic control (33.8%), hypoglycemia (22.1%), and increased glycemic variability (18.8%). Glycated hemoglobin decreased by 6 mmol/mol (95% CI, -5 to -6 mmol/mol, P < 0.001) [-0.5%, 95% CI, -0.4 to -0.5, P < 0.001] during the follow-up. The percentage of patients with severe hypoglycemia decreased from 14.9% to 0.9% (P < 0.001). We observed an inverse correlation between final HbA1c levels and CGM adherence (R = -0.24, P < 0.001) or percentage of time with active hybrid closed-loop functions (R = -0.25, P < 0.001). Conclusions: CSII treatment was associated with a sustained improvement in glycemic control in the Spanish population. This benefit was greater among patients with higher CGM or active hybrid closed-loop functions adherence. The protocol was publicly registered at ClinicalTrials.gov (NCT04761094).

Abstract
Objective Regarding the effects and practical application of insulin pumps on patients with type 1 diabetes mellitus (T1DM), the real-world evidence is limited especially concerning the incidence of hypoglycemia. This study aimed to compare the efficacy of continuous subcutaneous insulin infusion (CSII) therapy with multiple daily injection (MDI) therapy on glycemic metrics evaluated by retrospective continuous glucose monitoring (CGM) in Chinese patients with T1DM. Methods In total, 362 T1DM Chinese patients from the outpatient department of the Second Xiangya Hospital, Central South University, who underwent intensive insulin therapy and used a retrospective CGM system were included in this retrospective cross-sectional study. Comprehensive analysis of clinical and biological features and retrospective CGM derived-metrics was performed on the 362 enrolled T1DM patients who underwent CSII (n = 61) or MDI (n = 301) therapy (defined as 4 or more insulin injections per day). Results Our findings demonstrated that patients who underwent CSII therapy, compared with those who received MDI therapy, had lower levels of hemoglobin A1c (HbA1c) and fasting blood glucose; moreover, CSII therapy was associated with better glycemic outcomes in terms of increasing time in range (TIR), decreasing time above range (TAR), and achieving CGM-associated targets of TIR ≥70% and TAR <25%. However, patients who underwent CSII therapy did not experience decreasing time below range (TBR), achieving CGM-associated targets of TBR <4%, and reduction of the risk of hypoglycemia as evidenced by comparing TBR and low blood glucose index (LBGI) between the two treatment regimens. The parameters of glycemic variability, such as standard deviation of glucose (SD), mean amplitude glycemic excursion (MAGE), and large amplitude glycemic excursion (LAGE) in T1DM patients who underwent CSII therapy outperformed. Conclusion Our results provided further evidence that CSII therapy is safe and effective for management of Chinese T1DM patients, which was confirmed by a lower HbA1c level and better CGM-derived metrics but no demonstration of improvment in the risk of hypoglycemia. To achieve more satisfactory glycemic outcomes through the utilization of CSII therapy for Chinese T1DM patients, a strong physician-patient relationship is essential.

Abstract
INTRODUCTION Fear of hypoglycemia (FOH) is a phenomenon that affects people with diabetes experiencing hypoglycemia. On the one hand, FOH is an adaptive mechanism that helps to protect patients from hypoglycemia and its consequences. On the other hand, the non-normative level of FOH causes anxiety and tension, disturbs normal functioning, and makes normoglycemia maintenance difficult. OBJECTIVE The main objective of this review was to describe factors influencing FOH and methods of measurement of FOH levels. Moreover, we highlighted the impact of the new technologies used in diabetes therapy on FOH and different therapeutic possibilities helping patients cope with excessive levels of FOH. We also presented clinical cases of patients with high FOH levels met in clinical practice and discussed methods to better diagnose and assist people with this kind of problem. METHODS We searched for studies and articles via PubMed using the keywords fear of hypoglycemia, diabetes, and hypoglycemia. From screened documents identified from literature search, 67 articles were included in our review. RESULTS We divided results from literature screening into five parts: fear of hypoglycemia and hypoglycemia definition, risk factors for the FOH, methods of measuring levels of FOH, therapies for the FOH, and modern technologies. We also described clinical examples of abnormal fear of hypoglycemia in patients. CONCLUSION The review highlights the importance of taking into consideration fear of hypoglycemia phenomenon in diabetic patients in everyday clinical practice.

Abstract
AIMS/HYPOTHESIS We aimed to compare diabetic retinopathy outcomes in people with type 1 diabetes following introduction of continuous subcutaneous insulin infusion (CSII) therapy with outcomes in people receiving continuing therapy with multiple daily insulin injections (MDI). METHODS This is a retrospective cohort study using the Scottish Care Information - Diabetes database for retinal screening outcomes and HbA1c changes in 204 adults commenced on CSII therapy between 2013 and 2016, and 211 adults eligible for CSII during the same period but who continued on MDI therapy. Diabetic retinopathy progression (time to minimum one-grade worsening in diabetic retinopathy from baseline grading) was plotted for CSII and MDI cohorts using Kaplan-Meier curves, and outcomes were compared using multivariate Cox regression analysis adjusting for age, sex, baseline HbA1c, blood pressure, cholesterol, smoking status and socioeconomic quintile. Impact of baseline HbA1c and change in HbA1c on diabetic retinopathy progression was assessed within CSII and MDI cohorts. RESULTS CSII participants were significantly younger, were from less socially deprived areas, and had lower HbA1c and higher diastolic BP at baseline. There was a larger reduction in HbA1c at 1 year in those on CSII vs MDI (-6 mmol/mol [-0.6%] vs -2 mmol/mol [-0.2%], p < 0.01). Diabetic retinopathy progression occurred in a smaller proportion of adults following commencement of CSII vs continued MDI therapy over mean 2.3 year follow-up (26.5% vs 18.6%, p = 0.0097). High baseline HbA1c (75 mmol/mol [9%]) was associated with diabetic retinopathy progression in the MDI group (p = 0.0049) but not the CSII group (p = 0.93). Change in HbA1c at follow-up, irrespective of baseline glycaemic status, did not significantly affect diabetic retinopathy progression in either group. CONCLUSIONS/INTERPRETATION CSII was associated with reduced diabetic retinopathy progression compared with continued MDI therapy, and may be protective against diabetic retinopathy progression for those with high baseline HbA1c. Progression of diabetic retinopathy over 3 years was not associated with a change in HbA1c.

Abstract
Monitoring blood glucose levels for diabetic patients is critical to achieve tight glycaemic control. As none of the current antidiabetic treatments restore lost functional β-cell mass in diabetic patients, insulin injections and the use of insulin pumps are most widely used in the management of glycaemia. The use of advanced and intelligent chemical engineering, together with the incorporation of micro- and nanotechnological-based processes have lately revolutionized diabetic management. The start of this concept goes back to 1974 with the description of an electrode that repeatedly measures the level of blood glucose and triggers insulin release from an infusion pump to enter the blood stream from a small reservoir upon need. Next to the insulin pumps, other drug delivery routes, including nasal, transdermal and buccal, are currently investigated. These processes necessitate competences from chemists, engineers-alike and innovative views of pharmacologists and diabetologists. Engineered micro and nanostructures hold a unique potential when it comes to drug delivery applications required for the treatment of diabetic patients. As the technical aspects of chemistry, biology and informatics on medicine are expanding fast, time has come to step back and to evaluate the impact of technology-driven chemistry on diabetics and how the bridges from research laboratories to market products are established. In this review, the large variety of therapeutic approaches proposed in the last five years for diabetic patients are discussed in an applied context. A survey of the state of the art of closed-loop insulin delivery strategies in response to blood glucose level fluctuation is provided together with insights into the emerging key technologies for diagnosis and drug development. Chemical engineering strategies centered on preserving and regenerating functional pancreatic β-cell mass are evoked in addition as they represent a permanent solution for diabetic patients.

Abstract
PURPOSE OF REVIEW The aim of the present review is to gather recent reports on the use of pancreas and islet transplantation and conventional insulin therapy for treating patients experiencing diabetes and its related complications. The present review directs attention to the current status, challenges and perspectives of these therapies and sheds light on potential future cellular therapies. RECENT FINDINGS The risks and benefits of diabetes treatment modalities continue to evolve, altering the risk versus benefit calculation for patients. As continuous subcutaneous insulin infusion and monitoring technologies demonstrate increasing effectiveness in achieving better diabetes control and reducing hypoglycemia frequency, so are pancreas and islet transplantation improving and becoming more effective and safer. Both beta-cell replacement therapies, however, are limited by a dependence on immunosuppression and a shortage of cadaver donors, restricting more widespread and safer deployment. Based on the effectiveness of clinical beta-cell replacement for lengthening lifespan and improving quality of life, scientists are aggressively investigating alternative cell sources, transplant platforms, and means of preventing immunological damage of transplanted cells to overcome these principle limitations. SUMMARY Essential goals of diabetes therapy are euglycemia, avoidance of hypoglycemia, and prevention or stabilization of end-organ damage. With these goals in mind, all therapeutic options should be considered.

Abstract
Hypoglycaemia is common in patients with type 1 diabetes and type 2 diabetes and constitutes a major limiting factor in achieving glycaemic control among people with diabetes. While hypoglycaemia is defined as a blood glucose level under 70 mg/dL (3.9 mmol/L), symptoms may occur at higher blood glucose levels in individuals with poor glycaemic control. Severe hypoglycaemia is defined as an episode requiring the assistance of another person to actively administer carbohydrate, glucagon, or take other corrective actions to assure neurologic recovery. Hypoglycaemia is the most important safety outcome in clinical studies of glucose lowering agents. The American Diabetes Association Standards of Medical Care recommends that a management protocol for hypoglycaemia should be designed and implemented by every hospital, along with a clear prevention and treatment plan. A tailored approach, using clinical and pathophysiologic disease stratification, can help individualize glycaemic goals and promote new therapies to improve quality of life of patients. Data from recent large clinical trials reported low risk of hypoglycaemic events with the use of newer anti-diabetic drugs. Increased hypoglycaemia risk is observed with the use of insulin and/or sulphonylureas. Vulnerable patients with T2D at dual risk of severe hypoglycaemia and cardiovascular outcomes show features of "frailty." Many of such patients may be better treated by the use of GLP-1 receptor agonists or SGLT2 inhibitors rather than insulin. Continuous glucose monitoring (CGM) should be considered for all individuals with increased risk for hypoglycaemia, impaired hypoglycaemia awareness, frequent nocturnal hypoglycaemia and with history of severe hypoglycaemia. Patients with impaired awareness of hypoglycaemia benefit from real-time CGM. The diabetes educator is an invaluable resource and can devote the time needed to thoroughly educate the individual to reduce the risk of hypoglycaemia and integrate the information within the entire construct of diabetes self-management. Conversations about hypoglycaemia facilitated by a healthcare professional may reduce the burden and fear of hypoglycaemia among patients with diabetes and their family members. Optimizing insulin doses and carbohydrate intake, in addition to a short warm up before or after the physical activity sessions may help avoiding hypoglycaemia. Several therapeutic considerations are important to reduce hypoglycaemia risk during pregnancy including administration of rapid-acting insulin analogues rather than human insulin, pre-conception initiation of insulin analogues, and immediate postpartum insulin dose reduction.

Abstract
BACKGROUND We aimed to explore the impact of externally worn diabetes technologies on sexual behavior and activity, body image, and anxiety in adopters and nonadopters of these devices. METHODS People with type 1 diabetes aged 16-60 years living in Western Australia were invited to complete an online survey. RESULTS Of the 289 respondents (mean age 34.3 years), 45% used continuous subcutaneous insulin infusion (CSII) and 35% used continuous glucose monitoring (CGM). Approximately half of CSII users stated that the pump interferes with sex. Of these, 75% disconnect their pump during sexual activity to avoid this issue. Comfort during sex influenced the location of the CSII insertion site in 22% of respondents, with the abdomen being preferred. One in four non-CSII users cited sex-related concerns as a factor for not adopting the technology. CGM interfered with sexual activity in 20% of users, but did not commonly affect CGM placement (only 18%). Sexual activity was reported as a factor for not adopting the technology in 10% of non-CGM users. No differences in body dissatisfaction (P = .514) or anxiety (P = .304) between CSII and non-CSII users were observed. No differences in sexual activity and behavior between technology users and nontechnology users were observed. CONCLUSION Wearable technologies impact upon sexual activity and this influences the decision to adopt the technology. Despite this, technology users are similar in terms of sexual behavior, anxiety, and body image compared to nontechnology users. Where appropriate, these data can be used to identify potential concerns, address strategies to mitigate them, and inform people with diabetes when considering adopting external technologies.

Long-term effects of continuous subcutaneous insulin infusion in adults with type 1 diabetes mellitus patients: Results of a public healthcare system. ACTA ACUST UNITED AC 2020; 68:116-122. [PMID: 32007441 DOI: 10.1016/j.endinu.2019.10.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Revised: 10/11/2019] [Accepted: 10/30/2019] [Indexed: 12/27/2022]
Abstract
AIM To evaluate the long-term clinical effect of continuous subcutaneous insulin infusion (CSII) in adult type 1 diabetes mellitus (T1DM) patients in a regional public healthcare system real-world scenario. METHODS All adult T1DM patients on CSII for ≥10 years subjected to follow-up in the regional Castilla-La Mancha Public Health Service were included. The primary efficacy outcome was the variation in HbA1c during follow-up. Direct patient data were compiled through the web-based Spanish national registry on CSII therapy. RESULTS A total of 69 T1DM adult patients were treated with insulin pumps for ≥10 years in our region. The mean age was 45.0±10.5 years, with a T1DM duration of 13.9±8.5 years. The mean duration of CSII therapy was 11.4±2.1 years. The main indications for treatment were high glucose variability (39%), problematic hypoglycemia (26%), and HbA1c >53mmol/mol (7%) on multiple daily injections (20%). Sensor-augmented pump therapy was used by 31% of the patients. Glycosylated hemoglobin did not change during follow-up (58±11mmol/mol vs. 58±11mmol/mol; 7.5±1.0 vs. 7.5±1.0; p=0.66). However, the percentage of patients with at least one episode of severe hypoglycemia during the last year and unnoticed hypoglycemia decreased from 36% to 7% (p=0.006) and from 38% to 32% (p<0.001), respectively. The proportion of subjects with ≥1 episode of diabetic ketoacidosis in the last year decreased from 30% to 6% (p=0.045). CONCLUSIONS The reduction of severe hypoglycemia without deterioration of glycemic control can be sustained over long-term CSII therapy.

Abstract
Technological advances have had a major effect on the management of type 1 diabetes. In addition to blood glucose meters, devices used by people with type 1 diabetes include insulin pumps, continuous glucose monitors, and, most recently, systems that combine both a pump and a monitor for algorithm-driven automation of insulin delivery. In the next 5 years, as many advances are expected in technology for the management of diabetes as there have been in the past 5 years, with improvements in continuous glucose monitoring and more available choices of systems that automate insulin delivery. Expansion of the use of technology will be needed beyond endocrinology practices to primary-care settings and broader populations of patients. Tools to support decision making will also need to be developed to help patients and health-care providers to use the output of these devices to optimise diabetes management.

Abstract
Aims: To analyze prevalence and clinical effect of continuous subcutaneous insulin infusion (CSII) in adult type 1 diabetes mellitus (T1DM) patients in a public health system real-world scenario. Materials and Methods: All adult T1DM patients on CSII being followed at Castilla-La Mancha Health Public Service were included. Primary efficacy outcome was the change in HbA1c during the follow-up. Secondary efficacy outcomes included evaluation of the following variables: insulin pump indications, diabetes complication rates, insulin and pump use, continuous glucose monitoring use, patients achieving an HbA1c decrease ≥6 mmol/mol (0.5%) with or without severe hypoglycemia, and discontinuations. Direct patient data were typed through the web-based Spanish national registry on CSII therapy by nine diabetologists from eight different health care areas. Results: A total of 7% of T1DM adult patients were treated with insulin pumps in our region, with a regional prevalence of 18.7 CSII patients/100,000 inhabitants. Three hundred thirteen patients were analyzed with a mean age of 34.1 ± 11.0 years and T1DM duration of 16.6 ± 9.7 years. Mean duration of CSII therapy was 6.2 ± 4.0 years. Data completion was 91.2%. Main indications for treatment were high glucose variability (36%) and suboptimal glycemic control (32%). Mean duration of CSII therapy was 6.2 ± 4.0 years. Sensor-augment pump therapy was used by 26% of the patients. Glycated hemoglobin decreased to -5 mmol/mol (95% CI -6 to -3 mmol/mol; P < 0.001) during the follow-up (Mean difference in change -0.4%, 95% CI -0.5 to -0.2; P < 0.001). Percentage of patients with severe hypoglycemia decreased from 32% to 13% (P < 0.001). Frequent nonsevere hypoglycemia, severe hypoglycemia, and diabetic ketoacidosis were less frequent among patients using higher number of daily basal rates at the study end. The rate of CSII interruption was 3.8%. Conclusions: Prevalence of CSII therapy in our region remains under 10% of adult T1DM patients, although CSII treatment was associated with a sustained improvement in glycemic control.

Abstract
INTRODUCTION To describe and compare the routine use of continuous subcutaneous insulin infusion (CSII) in type 1 diabetes (T1D) patients with and without continuous glucose monitoring (CGM) in routine clinical practice and its relationship with glycemic outcomes. METHODS Retrospective observational case-control study collecting routine use of CSII and CGM in T1D patients between January 2016 and December 2016. Patients with T1D using sensor augmented pump (SAP) were matched by sex and disease duration in a 1:3 ratio with those treated only with CSII. Patients used a Paradigm Veo or 640G Medtronic-Minimed® insulin pump with or without a glucose sensor (Enlite, Medtronic-Minimed®) for at least 12 months. RESULTS A total of 160 subjects with T1D were included, 40 using SAP and 120 on CSII (age 47 ± 12 years, 88 women, diabetes duration 29 ± 9.0 years, 10 ± 4.7 years on CSII, HbA1C 7.6 ± 0.8%). Those in SAP therapy used the sensor 63% of time, performed less self-monitored blood glucose (SMBG)/day (3.3 ± 1.9 vs. 4.5 ± 2.0; p < 0.01), more bolus/day (6.2 ± 3.6 vs. 4.8 ± 1.6; p < 0.05), more basal insulin segment/day (6.5 ± 2.1 vs. 5.9 ± 1.5; p < 0.05), and more suspension time of the pump (97 ± 93 vs. 9.6 ± 20 min/day; p < 0.0001). Regarding metabolic control, SAP therapy patients had lower HbA1c (7.4 ± 0.7 vs. 7.7 ± 0.9%; p = 0.068), lower average SMBG value (151 ± 32 vs. 163 ± 30 mg/dL; p < 0.05), a lower percentage of SMBG values greater than 180 mg/dL (30 ± 19 vs. 37 ± 16%; p < 0.05) with no differences in SMBG values less than 70 mg/dL (12 ± 8.0 vs. 9.8 ± 9.8%; p = 0.33) compared with patients on CSII. There were no differences in bolus wizard targets or in insulin/carbohydrate ratios per day. CONCLUSION In a real-world setting, SAP therapy is associated with more self-adjustments of insulin therapy when compared to CSII alone. This could result in an improvement in glucose control.

ACTA ACUST UNITED AC 2019; 66:534-539. [PMID: 31133475 DOI: 10.1016/j.endinu.2019.03.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2018] [Revised: 03/14/2019] [Accepted: 03/20/2019] [Indexed: 10/26/2022]
Abstract
OBJECTIVE Less than one third of patients with type 1 diabetes mellitus (T1DM) achieve the cut-off value proposed as good metabolic control by most guidelines, HbA1c<7%. However, HbA1c reductions and prevention of severe hypoglycemia (SH) have shown clinically relevant benefits. The study objective therefore was to assess the effectiveness of continuous subcutaneous insulin infusion (CSII) therapy at 5 years of follow-up in a cohort of patients attending a specialized unit using HbA1c reduction and abscence of SH as combined goals. METHODS A retrospective, observational study on 178 patients with T1DM who started CSII treatment at Hospital Clinic of Barcelona between 2003 and 2008. HbA1c levels at baseline and after 5 years of treatment with CSII and presence or absence of SH were recorded. The combined variables calculated included: a) HbA1c reduction by≥0.5 points and absence of SH in the last 2 years; b) HbA1c at 5 years<7.5% and no SH in the last 2 years; c) HbA1c<8.5% and no HG in the last 2 years, and d) HbA1c reduction by≥0.5 points and/or HbA1c<7.5% at 5 years with no SH in the last 2 years of follow-up. RESULTS Twenty-seven of the 178 patients were excluded due to loss to follow-up or CSII discontinuation. A total of 151 patients (aged 37.4±10.5 years, 64% women, diabetes duration of 19.2±10.7 years) were therefore analyzed. The 2 main reasons for starting CSII were suboptimal metabolic control (60.9%) and severe hypoglycemia/hypoglycemia unawareness (28.5%). HbA1c levels in the total cohort and in patients with suboptimal metabolic control were 8.0±1.2 and 8.4±1.1% at CSII start and 7.8±1.2 and 8.0±1.3% at 5 years of treatment (P=.104 and P=.016) respectively. In the overall cohort, 55.5% of patients achieved at 5 years the combined goal of HbA1c<7.5% and/or HbA1c reductions≥0.5% without SH. CONCLUSIONS After 5 years of CSII therapy, more than half of the patients achieved the combined goal of significant HbA1c reduction and absence of SH. The use of combined goals offers the opportunity to assess the effectiveness of T1DM treatment from a clinically more meaningful point of view.

Abstract
There continues to be uncertainty about the effectiveness in Type 1 diabetes of insulin pump therapy (continuous subcutaneous insulin infusion, CSII) vs. multiple daily insulin injections (MDI). This narrative review discusses the reasons for this uncertainty, summarizes the current evidence base for CSII and suggests some future research needs. There are difficulties in interpreting trials of CSII because effectiveness varies widely due to factors such as differing baseline control, suboptimal use of best CSII practices, and psychological factors, for example, high external locus of control, non-adherence and lack of motivation. Many summary meta-analyses are also misleading because of poor trial selection (e.g. short duration, obsolete pumps, low baseline rate of hypoglycaemia) and reliance on mean effect size for decision-making. Both MDI and CSII can achieve strict glycaemic control without hypoglycaemia in some people with Type 1 diabetes, especially those who are motivated and have undergone structured diabetes education, and with high levels of ongoing input from healthcare professionals. CSII is particularly effective in those people with Type 1 diabetes who have not achieved target HbA1c levels without disabling hypoglycaemia using best attempts with MDI, and here there can be valuable and substantial improvement. Insulin pumps are safe, effective and accepted when used in newly diagnosed diabetes, particularly in children, where MDI may not be practicable. Future research needs include more studies on mortality associated with insulin pumps where registry data have suggested lower rates vs. MDI; and psychological strategies to improve non-adherence and suboptimal glycaemic outcomes on CSII.

Abstract
OBJECTIVE There is scarce information regarding the performance of a specific, structured education program addressed to patients with type 1 diabetes (T1D) using continuous subcutaneous insulin infusion (CSII) including both routine use of the therapy and patient experience evaluation. We aimed to assess the routine use of CSII and patient's experience and satisfaction regarding a specific structured patient self-management education and care program. METHODS A retrospective, observational, cross-sectional study collecting CSII routine use downloaded data. Patient experience and satisfaction were evaluated using an anonymous online survey covering different aspects of CSII self-management education and care program. RESULTS 380 T1D subjects were included (aged 45.3±12.17 years, 62.1% women, diabetes duration 27.8±10.3 years, 9.7±4.7 years on CSII, HbA1c 7.7+1.0%; 61.0±7.9mmol/mol). Participants with HbA1c≤7.5% (58mmol/mol, n=178) did more SMBGs per day (4.4±2.1 vs. 3.9±1.9); used more boluses (5.0±1.8 vs. 4.5±2.0); the percentage of insulin given as bolus was higher (50.1±12.8 vs. 44.9±13.2%); the night bolus wizard (BW) high glucose target was lower (125.9±4.4 vs. 130.5±12.8mg/dl) and time on CSII therapy was shorter (8.9±4.6 vs. 10.3±4.6 years. p<0.05 all comparisons). More SMBG/day, shorter duration of CSII treatment, a lower BW low glucose target at night, a lower BW high glucose target at night, total insulin dose per day and total number of carbohydrates per day were related with better HbA1c levels. 60% of 373 patients answered the questionnaire. The response to the different aspects of the educational program was homogeneously highly satisfactory. Seventy-seven percent of patients scored the program as very useful. Ninety-three percent of CSII users would not return to their previous insulin treatment. CONCLUSIONS The analysis of routine clinical use of CSII by T1D patients demonstrates that glucose control may be associated with some pump usage and adherence parameters. The overall user experience and satisfaction with our CSII self-management education and care program was remarkably favorable.

Abstract
AIM To describe continuous subcutaneous insulin infusion (CSII) characteristics in type 1 diabetes mellitus (T1DM) children and adolescents using a standardized protocol in routine clinical settings in Qatar. METHODS A total of 138 T1DM patients (62 males; 76 females; mean age 9.8 ± 3.4 years) with a mean diabetes duration of 2.4 ± 1.9 years initiated CSII (MiniMed® Veo®™ and MiniMed® 640 G insulin pumps; Medtronic, Northridge, CA, USA) in 2016 and 2017. CSII characteristics and glycated hemoglobin (HbA1c) were evaluated 1 year after treatment initiation. RESULTS At 1 year after treatment initiation, the insulin dose had significantly increased (from 0.59 ± 0.23 to 0.74 ± 0.26 U/kg body weight per 24; P < 0.05), and the HbA1c level had significantly decreased (from 9.7 ± 1.3 to 8.1 ± 0.6%; P < 0.05). More than 92% of patients used the Bolus Wizard feature of the insulin pump at the following settings: insulin-to-carbohydrate ratio 19.2 ± 9.3 g; insulin sensitivity factor 131 ± 68 mg/dl; target range 91 ± 9.3-135 ± 14.2 mg/dl; active insulin time 3.8 ± 0.8 h. CONCLUSION Our results show that CSII may significantly improve glucose control in T1D children and adolescents who use a standardized protocol. A reduction of HbA1c by - 1.6% was achieved at 1 year after CSII initiation. These results need to be confirmed in a study with a longer duration.

Abstract
BACKGROUND Insulin pump therapy (IPT) is a technological advancement that has been developed to help people manage Type 1 diabetes (T1D). However, ways of managing diabetes requiring the implementation of health technologies bring new complexities and a need to understand the factors which enable people with T1D to incorporate a novel device. This new comprehension could provide an exemplar for people with long-term conditions to incorporate new technologies more generally. OBJECTIVE To determine what influences the incorporation, adaptation and use of IPT into the everyday lives of people living with diabetes. DESIGN Critical interpretive synthesis (CIS) using systematic searches undertaken in 7 electronic databases of literature, published 2008 onwards. RESULTS A total of 4998 titles were identified, 274 abstracts reviewed, 39 full articles retrieved and 22 papers selected for analysis. Three themes emerged which were of relevance to the introduction and use of IPT; Tensions between expectations and experiences in adoption and early adaptation; Negotiation of responsibility and accessing support; Reflexivity, active experimentation and feedback. CONCLUSIONS This CIS builds on earlier reviews on lived experiences of IPT. Novel insights are offered through examination of the experiences of pump users from children through to adults, their families and health-care professionals. Expectations of what the device can do to improve self-management impacts on the early stages of adoption as the reality of the technology requires substantial thought and action. Areas for intervention to improve IPT incorporation include establishing who is responsible for management tasks of the device and enabling navigation to further means of support and resources.

Abstract
OBJECTIVE To compare continuous subcutaneous insulin infusion (CSII) therapy with multiple daily insulin (MDI) therapy on metabolic control in children and adolescents with type 1 diabetes mellitus (T1DM) over the long term. METHODS Fifty-two T1DM patients treated with CSII and monitored for at least one year prior to and at least five years following CSII were included. Thirty-eight age and sex-matched MDI controls with a 5-year follow up were recruited. RESULTS Mean age of the subjects, duration of diabetes and CSII therapy were 17.0±4.8 years, 10.7±2.8 years and 7.7±1.5 years respectively. Mean hemoglobin A1c (HbA1c) in the year prior to CSII, during the first year of treatment and after 5 years of CSII were 7.3±1% (56 mmol/mol), 7.0±0.7% (53 mmol/mol) and 7.8±1.3% (62 mmol/mol) respectively. Initial and 5-year mean HbA1C levels of controls were 7.9±1.08% and 8.6±1.8%. Mean HbA1c values were significantly lower in those receiving CSII therapy throughout follow-up. Basal and total insulin doses were significantly lower in the CSII group at all times. HbA1c was compared between subjects by age (0-5, 6-11 and 12-18 years) with no significant difference between them. CONCLUSION Although CSII mean HbA1c values exceeded accepted good metabolic control limits after 5 years, CSII produces better HbA1c control at all times and in all age groups compared to MDI.

Abstract
Advances in technology allowing improved insulin delivery and glucose monitoring can significantly reduce the burden of hypoglycaemia when used appropriately. However, limitations of the current technology, and the skills, commitment and motivation required to use them, mean that it does not work for all people. Education and informed professional support are key to success. In the context of problematic hypoglycaemia, data suggest that newer technology has lower efficacy and uptake in those with most need. Identifying the causes of hypoglycaemia and understanding some of the underlying behavioural drivers may prove useful and psycho-educational strategies may be effective in selected individuals. Ultimately, as in many spheres of medicine, successful management of problematic hypoglycaemia depends upon matching the right treatment to the right individual.

Abstract
AIMS To assess safety and benefits of continuous subcutaneous insulin infusion (CSII) therapy in a cohort of type 1 diabetes patients in Spain. METHODS A web-based national registry was created by the Working Group of the Spanish Diabetes Association. All patients on CSII being followed at selected referral centers were included. A cross-sectional analysis was performed. RESULTS A total of 1275 patients were included. Data completion for patients on CSII was 67 ± 32%. Indications for treatment were suboptimal glycemic control (32%), high glucose variability (24%), preconception care (14%) and hypoglycemia (11%). In the patients on CSII for ≥1 year (n = 843, mean CSII duration of 5 years), HbA1c decreased by 5 mmol/mol (0.5%) in the whole population and by 8 mmol/mol (0.7%) in subjects with suboptimal glycemic control as CSII indication. Percentage of patients achieving HbA1c ≤ 53 mmol/mol (7%) increased from 20% before CSII to 34% at the end of follow-up. Severe hypoglycemia decreased from 29% to 5%. The rate of discontinuation was 9.5%. HbA1c was lower in patients using bolus advisor and temporary basal rates. CONCLUSIONS CSII was associated with a sustained improvement in glycemic control and a reduction in severe hypoglycemia. The use of advanced CSII settings was related to better glycemic control.

Abstract
BACKGROUND Insulin is generally administered to people with type 1 diabetes mellitus (T1DM) using multiple daily injections (MDIs), but can also be delivered using infusion pumps. In the UK, pumps are recommended for patients with the greatest need and adult use is less than in comparable countries. Previous trials have been small, of short duration and have failed to control for training in insulin adjustment. OBJECTIVE To assess the clinical effectiveness and cost-effectiveness of pump therapy compared with MDI for adults with T1DM, with both groups receiving equivalent structured training in flexible insulin therapy. DESIGN Pragmatic, multicentre, open-label, parallel-group cluster randomised controlled trial, including economic and psychosocial evaluations. After participants were assigned a group training course, courses were randomly allocated in pairs to either pump or MDI. SETTING Eight secondary care diabetes centres in the UK. PARTICIPANTS Adults with T1DM for > 12 months, willing to undertake intensive insulin therapy, with no preference for pump or MDI, or a clinical indication for pumps. INTERVENTIONS Pump or MDI structured training in flexible insulin therapy, followed up for 2 years. MDI participants used insulin analogues. Pump participants used a Medtronic Paradigm® VeoTM (Medtronic, Watford, UK) with insulin aspart (NovoRapid, Novo Nordisk, Gatwick, UK). MAIN OUTCOME MEASURES Primary outcome - change in glycated haemoglobin (HbA1c) at 2 years in participants whose baseline HbA1c was ≥ 7.5% (58 mmol/mol). Key secondary outcome - proportion of participants with HbA1c ≤ 7.5% at 2 years. Other outcomes at 6, 12 and 24 months - moderate and severe hypoglycaemia; insulin dose; body weight; proteinuria; diabetic ketoacidosis; quality of life (QoL); fear of hypoglycaemia; treatment satisfaction; emotional well-being; qualitative interviews with participants and staff (2 weeks), and participants (6 months); and ICERs in trial and modelled estimates of cost-effectiveness. RESULTS We randomised 46 courses comprising 317 participants: 267 attended a Dose Adjustment For Normal Eating course (132 pump; 135 MDI); 260 were included in the intention-to-treat analysis, of which 235 (119 pump; 116 MDI) had baseline HbA1c of ≥ 7.5%. HbA1c and severe hypoglycaemia improved in both groups. The drop in HbA1c% at 2 years was 0.85 on pump and 0.42 on MDI. The mean difference (MD) in HbA1c change at 2 years, at which the baseline HbA1c was ≥ 7.5%, was -0.24% [95% confidence interval (CI) -0.53% to 0.05%] in favour of the pump (p = 0.098). The per-protocol analysis showed a MD in change of -0.36% (95% CI -0.64% to -0.07%) favouring pumps (p = 0.015). Pumps were not cost-effective in the base case and all of the sensitivity analyses. The pump group had greater improvement in diabetes-specific QoL diet restrictions, daily hassle plus treatment satisfaction, statistically significant at 12 and 24 months and supported by qualitative interviews. LIMITATION Blinding of pump therapy was not possible, although an objective primary outcome was used. CONCLUSION Adding pump therapy to structured training in flexible insulin therapy did not significantly enhance glycaemic control or psychosocial outcomes in adults with T1DM. RESEARCH PRIORITY To understand why few patients achieve a HbA1c of < 7.5%, particularly as glycaemic control is worse in the UK than in other European countries. TRIAL REGISTRATION Current Controlled Trials ISRCTN61215213.

Abstract
BACKGROUND Subcutaneous insulin infusion (CSII) therapy is a challenge for both patients and healthcare providers. The long-term CSII use is scarce. The aim of this study is to describe the impact of CSII therapy for 10 years of use at our center. METHODS This single-center retrospective study includes 162 type 1 diabetes patients using CSII for >3 years during October 2004 until October 2014. Data were collected through the electronic medical record system, cross-sectional analysis (telephone, e-mail, or social media), and CSII reports generated by Carelink Therapy Management Software (Medtronic, Northridge, CA). RESULTS Patients were analyzed in three age groups: 12-18, 19-24, and >25 years. All patients were treated with CSII for >3 years. Total daily dose of insulin was >0.9 U/(kg·day) in age group 12-18 years old, which was significantly higher than other two age groups (P < 0.05). Basal ratio was lower in younger age (<40%) and showed trend of increasing with age and longer diabetes duration (up to 44%). Younger patients used bolus wizard on regular basis (>75%), which was significantly higher than other age groups (P < 0.05). More than 50% of patients achieved glycated hemoglobin (HbA1c) <7.0% and >70% of patients achieved HbA1c <7.5%. HbA1c level significantly changed from baseline in all groups (P < 0.05). CONCLUSION Our study shows improved glucose control in long-term CSII users. A reduction of HbA1c levels by -1.1% was maintained during the study period.

Abstract
BACKGROUND We investigated the long-term effects of continuous subcutaneous insulin infusion (CSII) on glucose control and microvascular complications in patients with type 1 diabetes (T1D). METHODS A total of 157 patients (59 M/98 W; age 39.1 ± 14.8 years) with T1D who switched from multiple daily injections to CSII and used CSII for at least one year were included. HbA1c levels and status of microvascular complications before and while under CSII were analyzed, retrospectively. RESULTS The follow-up period was 4.0 ± 1.5 years. HbA1c significantly decreased from 8.4 ± 1.3 to 7.7 ± 1.3% (68 ± 14 to 61 ± 14 mmol/mol) after 1-year CSII and remained lower than pre-CSII levels during four years. Patients with pre-CSII HbA1c >8.0% (64 mmol/mol) showed significant improvement of HbA1c for four years, while those with pre-CSII HbA1c <8.0% showed no significant change. The prevalence of retinopathy, albuminuria, and chronic kidney disease (CKD) were respectively 39%, 12%, and 9% at CSII initiation. During follow-up, the incidence of retinopathy, albuminuria, and CKD were 3.6, 2.5 and 1.4/100 patient-years. Onset or progression of retinopathy occurred in 16 (27.1%) patients with diabetes duration >15 years, and in three (4.3%) patients with diabetes duration <15 years ( P < .01). CONCLUSION CSII was effective in improving HbA1c for up to four years, specifically in patients with HbA1c >8% (64 mmol/mol) prior to CSII. Incidence and progression rates of retinopathy and albuminuria were low, particularly in patients with a diabetes duration <15 years at CSII initiation. These results argue for not delaying a proposal of CSII initiation in T1D with sustained HbA1c >8% (64 mmol/mol).

Abstract
Cortisol has a distinct circadian rhythm with low concentrations at night, rising in the early hours of the morning, peaking on waking and declining over the day to low concentrations in the evening. Loss of this circadian rhythm, as seen in jetlag and shift work, is associated with fatigue in the short term and diabetes and obesity in the medium to long term. Patients with adrenal insufficiency on current glucocorticoid replacement with hydrocortisone have unphysiological cortisol concentrations being low on waking and high after each dose of hydrocortisone. Patients with adrenal insufficiency complain of fatigue, a poor quality of life and there is evidence of poor health outcomes including obesity potentially related to glucocorticoid replacement. New technologies are being developed that deliver more physiological glucocorticoid replacement including hydrocortisone by subcutaneous pump, Plenadren, a once-daily modified-release hydrocortisone and Chronocort, a delayed and sustained absorption hydrocortisone formulation that replicates the overnight profile of cortisol. In this review, we summarise the evidence regarding physiological glucocorticoid replacement with a focus on relevance to paediatrics.
