[PMID: 38376580 PMCID: PMC11055751 DOI: 10.1007/s00592-024-02239-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 01/13/2024] [Indexed: 02/21/2024]
Abstract
AIM The sympathetic nervous and hormonal counterregulatory responses to hypoglycaemia differ between people with type 1 and type 2 diabetes and may change along the course of diabetes, but have not been directly compared. We aimed to compare counterregulatory hormone and symptom responses to hypoglycaemia between people with type 1 diabetes, insulin-treated type 2 diabetes and controls without diabetes, using a standardised hyperinsulinaemic-hypoglycaemic clamp. MATERIALS We included 47 people with type 1 diabetes, 15 with insulin-treated type 2 diabetes, and 32 controls without diabetes. Controls were matched according to age and sex to the people with type 1 diabetes or with type 2 diabetes. All participants underwent a hyperinsulinaemic-euglycaemic-(5.2 ± 0.4 mmol/L)-hypoglycaemic-(2.8 ± 0.13 mmol/L)-clamp. RESULTS The glucagon response was lower in people with type 1 diabetes (9.4 ± 0.8 pmol/L, 8.0 [7.0-10.0]) compared to type 2 diabetes (23.7 ± 3.7 pmol/L, 18.0 [12.0-28.0], p < 0.001) and controls (30.6 ± 4.7, 25.5 [17.8-35.8] pmol/L, p < 0.001). The adrenaline response was lower in type 1 diabetes (1.7 ± 0.2, 1.6 [1.3-5.2] nmol/L) compared to type 2 diabetes (3.4 ± 0.7, 2.6 [1.3-5.2] nmol/L, p = 0.001) and controls (2.7 ± 0.4, 2.8 [1.4-3.9] nmol/L, p = 0.012). Growth hormone was lower in people with type 2 diabetes than in type 1 diabetes, at baseline (3.4 ± 1.6 vs 7.7 ± 1.3 mU/L, p = 0.042) and during hypoglycaemia (24.7 ± 7.1 vs 62.4 ± 5.8 mU/L, p = 0.001). People with 1 diabetes had lower overall symptom responses than people with type 2 diabetes (45.3 ± 2.7 vs 58.7 ± 6.4, p = 0.018), driven by a lower neuroglycopenic score (27.4 ± 1.8 vs 36.7 ± 4.2, p = 0.012). CONCLUSION Acute counterregulatory hormone and symptom responses to experimental hypoglycaemia are lower in people with type 1 diabetes than in those with long-standing insulin-treated type 2 diabetes and controls.

Abstract
AIMS/INTRODUCTION To develop and validate a simple prediction model for hypoglycemia risk in patients with type 2 diabetes. MATERIALS AND METHODS We prospectively analyzed the data of 1,303 subjects in a third-class hospital in Tianjin and followed up their hypoglycemia events at 3 and 6 months. The hypoglycemia risk prediction models for 3 and 6 months were developed and the model performance was evaluated. RESULTS A total of 340 (28.4%) patients experienced hypoglycemia within 3 months and 462 (37.2%) within 6 months during the follow-up period. Age, central obesity, intensive insulin therapy, frequency of hypoglycemia in the past year, and hypoglycemia prevention education entered both model3month and model6month. The area under the receiver operating characteristic curve of model3month and model6month were 0.711 and 0.723, respectively. The Youden index was 0.315 and 0.361, while the sensitivities were 0.615 and 0.714, and the specificities were 0.717 and 0.631. The calibration curves showed that the models were similar to reality. The decision curves implied that the clinical net benefit of the model was clear. CONCLUSIONS The study developed 3 and 6 month hypoglycemia risk prediction models for patients with type 2 diabetes. The discrimination and calibration of the two prediction models were good, and might help to improve clinical decision-making and guide patients to more reasonable self-care and hypoglycemia prevention at home.

Abstract
The colossal global burden of diabetes management is compounded by the serious complication of hypoglycemia. Protective physiologic hormonal and neurogenic counterregulatory responses to hypoglycemia are essential to preserve glucose homeostasis and avert serious morbidity. With recurrent exposure to hypoglycemic episodes over time, these counterregulatory responses to hypoglycemia can diminish, resulting in an impaired awareness of hypoglycemia (IAH). IAH is characterized by sudden neuroglycopenia rather than preceding cautionary autonomic symptoms. IAH increases the risk of subsequent sudden and severe hypoglycemic episodes in patients with diabetes. The postulated causative mechanisms behind IAH are complex and varied. It is therefore challenging to identify a single effective therapeutic strategy. In this review, we closely examine the efficacy and feasibility of a myriad of pharmaceutical interventions in preventing and treating IAH as described in clinical and preclinical studies. Pharmaceutical agents outlined include N-acetyl cysteine, GABA A receptor blockers, opioid receptor antagonists, AMP activated protein kinase agonists, potassium channel openers, dehydroepiandrosterone, metoclopramide, antiadrenergic agents, antidiabetic agents and glucagon.

Severe (level 3) hypoglycaemia occurrence in a real-world cohort of adults with type 1 or 2 diabetes mellitus (iNPHORM, United States). Diabetes Obes Metab 2023; 25:3736-3747. [PMID: 37700692 PMCID: PMC10958739 DOI: 10.1111/dom.15268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 08/17/2023] [Accepted: 08/18/2023] [Indexed: 09/14/2023]
Abstract
AIMS Among adults with insulin- and/or secretagogue-treated diabetes in the United States, very little is known about the real-world descriptive epidemiology of iatrogenic severe (level 3) hypoglycaemia. Addressing this gap, we collected primary, longitudinal data to quantify the absolute frequency of events as well as incidence rates and proportions. MATERIALS AND METHODS iNPHORM is a US-wide, 12-month ambidirectional panel survey (2020-2021). Adults with type 1 diabetes mellitus (T1DM) or insulin- and/or secretagogue-treated type 2 diabetes mellitus (T2DM) were recruited from a probability-based internet panel. Participants completing ≥1 follow-up questionnaire(s) were analysed. RESULTS Among 978 respondents [T1DM 17%; mean age 51 (SD 14.3) years; male: 49.6%], 63% of level 3 events were treated outside the health care system (e.g. by family/friend/colleague), and <5% required hospitalization. Following the 12-month prospective period, one-third of individuals reported ≥1 event(s) [T1DM 44.2% (95% CI 36.8%-51.8%); T2DM 30.8% (95% CI 28.7%-35.1%), p = .0404, α = 0.0007]; and the incidence rate was 5.01 (95% CI 4.15-6.05) events per person-year (EPPY) [T1DM 3.57 (95% CI 2.49-5.11) EPPY; T2DM 5.29 (95% CI 4.26-6.57) EPPY, p = .1352, α = 0.0007]. Level 3 hypoglycaemia requiring non-transport emergency medical services was more common in T2DM than T1DM (p < .0001, α = 0.0016). In total, >90% of events were experienced by <15% of participants. CONCLUSIONS iNPHORM is one of the first long-term, prospective US-based investigations on level 3 hypoglycaemia epidemiology. Our results underscore the importance of participant-reported data to ascertain its burden. Events were alarmingly frequent, irrespective of diabetes type, and concentrated in a small subsample.

Abstract
AIMS We aim to compare and correlate Gold and Clarke questionnaire scores with hypoglycaemic symptomatic responses between insulin-treated type 2 diabetes participants with and without IAH in a real-life study. METHODS Insulin-treated type 2 diabetes participants attending an outpatient diabetes clinic in Singapore were asked to complete the Gold and Clarke questionnaires, record capillary blood glucose (CBG) and hypoglycaemic symptoms for 4 weeks. RESULTS Data were collected from 153 participants (M:F = 98:55) with mean age 61.0 ± 9.4 years, duration of diabetes 19.5 ± 8.8 years and HbA1c 68 ± 17 mmol/mol (8.4 ± 1.5%). Gold and Clarke methods classified 19.6% and 26.8% of participants with IAH, respectively. Using CBG threshold of <3 mmol/L, significantly greater proportion of participants with intact awareness were experiencing autonomic symptoms than those with IAH with either method (Gold: 69% vs. 18%, p = 0.006; Clarke: 85% vs. 46%, p = 0.010). Significantly greater proportion of participants with IAH experienced no hypoglycaemia symptoms than those with intact awareness (Gold: 3.4% vs. 36%, p = 0.015; Clarke: 3.7% vs. 31%, p = 0.031). Participants with IAH had significantly higher rates of severe hypoglycaemia in the preceding year compared to those without (Gold: 17% vs. 3.3%; Clarke: 15% vs. 2.7%, p = 0.012). CONCLUSIONS Gold and Clarke questionnaires are appropriate tools in ascertaining IAH status in insulin-treated type 2 diabetes participants. This is the first time whereby the hypoglycaemia symptomology has robustly validated the Gold and Clarke questionnaire in insulin-treated type 2 diabetes participants.

Abstract
BACKGROUND To examine the impact of real-time continuous glucose monitoring (rtCGM) on psychosocial outcomes in adults with insulin-using type 2 diabetes (T2D). METHODS A total of 174 insulin-using adults with T2D completed questionnaires assessing diabetes distress, hypoglycemic confidence, hypoglycemic fear, device-related emotional burden, and device-related trust before and after a six-month trial of rtCGM. Hemoglobin A1c (HbA1c) was assessed at the same time points; impaired hypoglycemic awareness (IAH) was assessed at baseline. Change in psychosocial outcomes was examined with t tests, then modeled as a function of baseline HbA1c and IAH and simultaneous change in HbA1c in multiple regression analyses. RESULTS Respondents were predominantly male (57.5%) and non-Hispanic white (67.8%). Significant improvement over the trial was observed in hypoglycemic fear (P = .031), hypoglycemic confidence (P < .001), diabetes distress (P < .001), and device-related emotional burden (P < .001). Impaired hypoglycemic awareness at baseline predicted greater improvement in hypoglycemic fear (P = .002), hypoglycemic confidence (P = .003), diabetes distress (P = .013), and device-related emotional burden (P < .001). Higher baseline HbA1c was linked with greater improvement in hypoglycemic fear (P = .030); HbA1c change over the trial was positively associated with change in diabetes distress (P = .010) and device-related emotional burden (P = .003). CONCLUSIONS Introduction of rtCGM in adults with insulin-using T2D was associated with significant improvements in diabetes-related psychosocial outcomes over six months. Gains were significantly greater among participants reporting IAH and those with higher HbA1c at baseline, thus providing the first evidence regarding which users might more likely benefit.

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
AIMS To conduct a systematic review to summarize the definition, measurement tools, prevalence, and contributing factors of impaired awareness of hypoglycemia (IAH) in type 2 diabetes mellitus (T2DM). METHODS A reproducible search strategy was used to identify factors affecting IAH in T2DM in PubMed, MEDLINE, EMBASE, Cochrane, PsycINFO, and CINAHL from inception until 2022. Literature screening, quality evaluation, and information extraction were performed independently by 2 investigators. A meta-analysis of prevalence was performed using Stata 17.0. RESULTS The pooled prevalence of IAH in patients with T2DM was 22% (95%CI:14-29%). Measurement tools included the Gold score, Clarke's questionnaire, and the Pedersen-Bjergaard scale. IAH in T2DM was associated with sociodemographic factors (age, BMI, ethnicity, marital status, education level, and type of pharmacy patients visited), clinical disease factors (disease duration, HbAlc, complications, insulin therapy regimen, sulfonylureas use, and the frequency and severity of hypoglycemia), and behavior and lifestyle (smoking and medication adherence). CONCLUSION The study found a high prevalence of IAH in T2DM, with an increased risk of severe hypoglycemia, suggesting that medical workers should take targeted measures to address sociodemographic factors, clinical disease, and behavior and lifestyle to reduce IAH in T2DM and thus reduce hypoglycemia in patients.

Abstract
AIMS Impaired awareness of hypoglycaemia (IAH) has been reported to affect up to a third of people with type 1 diabetes. Whether the increased use of sensor technology has changed its prevalence remains unknown. The aim of this study was to investigate the current prevalence of IAH and its change over time in a cohort of individuals with type 1 diabetes. METHODS IAH was assessed using the modified Clarke questionnaire in adults with type 1 diabetes. Participants were recruited from the diabetes outpatient clinic from February 2020 through April 2021. The scores were compared to similar data collected during previous assessments in 2006, 2010 and 2016 respectively. RESULTS A total of 488 individuals (51.2% male) with a mean (±SD) age of 51.3 ± 15.9 years, median [Q1-Q3] diabetes duration of 30 [16-40] years and mean HbA1c of 60 ± 12 mmol/mol (7.7 ± 1.1%) were included. Sensors were used by 85% of the study population. IAH was present among 78 (16.0%) participants, whereas 86 (17.6%) participants had a history of severe hypoglycaemia. By comparison, the prevalence of IAH equalled 32.5% in 2006, 32.3% in 2010 and 30.1% in 2016 (p for trend <0.001), while the proportion of individuals reporting severe hypoglycaemia equalled 21.2%, 46.7% and 49.8% respectively (p for trend 0.010). Comparing sequential assessments over time, the proportion of individuals with persistent IAH decreased from 74.0% and 63.6% between 2006 and 2016 to 32.5% in 2020. CONCLUSIONS Among individuals with type 1 diabetes and high use of sensor technology, the current prevalence of IAH was 16%, about 50% lower as compared to previous years.

Abstract
Background Hypoglycemia has a major impact on patient health and glycemic management during insulin therapy for both type 1 (T1DM) and type 2 diabetes mellitus (T2DM). It is the rate-limiting complication in diabetes management that prevents stringent glucose control. Objectives To assess the knowledge and awareness about hypoglycemia as a complication of T2D in adults in Al Qassim, Saudi Arabia. Methods This is a cross-sectional study done among type 2 diabetes patients in Al-Qassim, Kingdom of Saudi Arabia, from January to June 2022. A previously validated online questionnaire was disseminated through social media to gather information from respondents. Participants were chosen via a simple random sampling technique. Data analysis was completed using SPSS (version 23; IBM Corp., Armonk, NY). Results Overall, 213 respondents were included in our study. The majority of them were females (70.9%). The participants' average age was 35.9 + 13.0 years. Our results revealed that the average awareness score of the study population was found to be 3.6 ± 1.1 (by using the Clarke method) and 3.7 ± 2.1 (by using the Gold method). Moreover, we found that impaired awareness of hypoglycemia's prevalence by Clarke's questionnaire was 52.1% and 53.5% by using the Gold questionnaire. In addition, almost half of the respondents reported weakness as a symptom of hypoglycemia over the last six months and unconsciousness over the last 12 months. Hypertension was the most commonly reported chronic disease by our participants. Lastly, factors such as age, gender, educational level, geographic distribution, and history of chronic illness did not show any significant association with impaired awareness of the prevalence of hypoglycemia. Conclusion According to our research, we concluded that patients with type 2 diabetes mellitus in the region of Al-Qassim, Saudi Arabia, had insufficient knowledge about hypoglycemia as a complication of T2D. Moreover, the impaired awareness of hypoglycemia in diabetic patients was found to be high. Hence, there is a need for interventional programs to raise public awareness.

Abstract
BACKGROUND People with impaired awareness of hypoglycemia (IAH) are at elevated risk of severe, potentially hazardous, hypoglycemia and would benefit from a device alerting to hypoglycemia. Heart rate variability (HRV) changes with hypoglycemia due to sympathetic activity. Since IAH is associated with suppressed sympathetic activity, we investigated whether hypoglycemia elicits a measurable change in HRV in patients with T1D and IAH. METHOD Eligible participants underwent a modified hyperinsulinemic euglycemic hypoglycemic clamp (glucose nadir, 43.1 ± 0.90 mg/dl), while HRV was measured by a VitalConnect HealthPatch. Measurements of HRV included Root Mean Square of the Successive Differences (RMSSD) and low to high frequency (LF:HF) ratio. Wilcoxon rank-sum test was used for testing within-subject HRV changes. RESULTS We included 12 participants (8 female, mean age 57 ± 12 years, mean HbA1c 57 ± 5 mmol/mol (7.4 ± 0.4%)). Symptoms increased from 4.0 (1.5-7.0) at euglycemia to 7.5 (5.0-11.0) during hypoglycemia (P = .003). In response to hypoglycemia, the LF:HF ratio and RMSSD increased when normalized for data obtained during euglycemia (both P < .01). The LF:HF ratio increased in 6 participants (50%) and declined in one other participant (8%). The RMSSD decreased in 3 (25%) and increased in 4 (33%) participants. In 2 patients, no change in HRV could be detected in response to hypoglycemia. CONCLUSIONS This study reveals that hypoglycemia-induced changes in HRV are retained in the majority of people with T1D and IAH, and that these changes can be detected by a wearable device. Real-time HRV seems usable for detection of hypoglycemia in patients with IAH.

Abstract
AIMS/INTRODUCTION We investigated the associations between a combination of lifestyle factors and changes to these factors and the subsequent risk of severe hypoglycemia (SH) in type 2 diabetes patients. MATERIALS AND METHODS Individuals with adult type 2 diabetes who underwent consecutive 2-year interval health screening programs from 2009 to 2012 from the Korean National Health Insurance Service database were included and followed up until 2018. Information on history of smoking status, alcohol consumption and physical activity, as well as changes to these factors, was obtained. The primary outcome was incident SH. RESULTS Of the 1,490,233 type 2 diabetes patients, 30,539 (2.1%) patients developed SH. Current smokers and heavy drinkers had increased risk of SH, compared with non-smokers and non-drinkers, respectively (hazard ratio 1.28, 95% confidence interval 1.23-1.34; hazard ratio 1.22, 95% confidence interval 1.15-1.30). However, regular physical activity was associated with reduced SH risk (hazard ratio 0.79, 95% confidence interval 0.77-0.82). A combination of unhealthy lifestyle habits was associated with increased SH risk in a dose-dependent fashion (P for trend <0.001). Compared with participants without changes in their unhealthy lifestyles, participants who improved lifestyles had decreased risk of SH. CONCLUSIONS Greater adherence to healthy lifestyle factors and any improvement in unhealthy lifestyle habits were associated with a substantially lower risk of SH in individuals with type 2 diabetes.

Abstract
INTRODUCTION The aim of this study was to determine the psychometric properties of the 12-Item Hypoglycemia Impact Profile (HIP12), a brief measure of the impact of hypoglycemia on quality of life (QoL) among adults with type 1 (T1D) or type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS Adults with T1D (n=1071) or T2D (n=194) participating in the multicountry, online study, 'Your SAY: Hypoglycemia', completed the HIP12. Psychometric analyses were undertaken to determine acceptability, structural validity, internal consistency, convergent/divergent validity, and known-groups validity. RESULTS Most (98%) participants completed all items on the HIP12. The expected one-factor solution was supported for T1D, T2D, native English speaker, and non-native English speaker groups. Internal consistency was high across all groups (ω=0.91-0.93). Convergent and divergent validity were satisfactory. Known-groups validity was demonstrated for both diabetes types, by frequency of severe hypoglycemia (0 vs ≥1 episode in the past 12 months) and self-treated episodes (<2 vs 2-4 vs ≥5 per week). The measure also discriminated by awareness of hypoglycemia in those with T1D. CONCLUSIONS The HIP12 is an acceptable, internally consistent, and valid tool for assessing the impact of hypoglycemia on QoL among adults with T1D. The findings in the relatively small sample with T2D are encouraging and warrant replication in a larger sample.

Abstract
AIMS/HYPOTHESIS Attenuated counterregulation after recurrent hypoglycaemia is a major complication of diabetes treatment. As there is previous evidence for the relevance of sleep in metabolic control, we assessed the acute contribution of sleep to the counterregulatory adaptation to recurrent hypoglycaemia. METHODS Within a balanced crossover design, 15 healthy, normal-weight male participants aged 18-35 years underwent three hyperinsulinaemic-hypoglycaemic clamps with a glucose nadir of 2.5 mmol/l, under two experimental conditions, sleep and sleep deprivation. Participants were exposed to two hypoglycaemic episodes, followed by a third hypoglycaemic clamp after one night of regular 8 h sleep vs sleep deprivation. The counterregulatory response of relevant hormones (glucagon, growth hormone [GH], ACTH, cortisol, adrenaline [epinephrine] and noradrenaline [norepinephrine]) was measured, and autonomic and neuroglycopenic symptoms were assessed. RESULTS Sleep deprivation compared with sleep dampened the adaptation to recurrent hypoglycaemia for adrenaline (p=0.004), and this pattern also emerged in an overall analysis including adrenaline, GH and glucagon (p=0.064). After regular sleep, the counterregulatory responses of adrenaline (p=0.005), GH (p=0.029) and glucagon (p=0.009) were attenuated during the 3rd clamp compared with the 1st clamp, but were preserved after sleep deprivation (all p>0.225). Neuroglycopenic and autonomic symptoms during the 3rd clamp compared with the 1st clamp were likewise reduced after sleep (p=0.005 and p=0.019, respectively). In sleep deprivation, neuroglycopenic symptoms increased (p=0.014) and autonomic symptoms were unchanged (p=0.859). CONCLUSIONS/INTERPRETATION The counterregulatory adaptation to recurrent hypoglycaemia is compromised by sleep deprivation between hypoglycaemic episodes, indicating that sleep is essential for the formation of a neurometabolic memory, and may be a potential target of interventions to treat hypoglycaemia unawareness syndrome.

Abstract
BACKGROUND Illness perceptions are important for patients with insulin-treated type 2 diabetes mellitus (T2DM) and impaired awareness of hypoglycemia (IAH), as they determine health-related behaviors and motivations. Patients with IAH in many countries have poor illness perception, and there is a paucity of research exploring the effectiveness of Common Sense Model (CSM)-based interventions in this population. OBJECTIVE To investigate the effects of a CSM-based intervention program on perceptions of illness in patients with insulin-treated T2DM and IAH. DESIGN Quasi-randomized controlled trialMethods: 78 patients with IAH receiving routine care were included. The intervention group (n = 39) participated in a CSM-based program, whereas the control group (n = 39) did not. Illness perceptions, coping styles, hypoglycemia fear, and awareness of hypoglycemia at baseline, 1 month, and 3 months were analyzed and compared between the two groups. RESULTS The intervention group exhibited significant improvements in consequences (β = -1.615, P = 0.032); personal control (β = -1.897, P = 0.006); treatment control (β = -1.274, P = 0.046); and positive coping style (β = 4.872, P = 0.002) at the 3-month follow-up, and timeline (β = 2.769, P = 0.004) at the 1-month follow-up. Hypoglycemia fear and awareness were not significantly improved in the intervention group compared with the control group. No intervention-related adverse events were observed. CONCLUSIONS A CSM-based intervention program can modify illness perceptions to an extent and improve the positive coping style in patients with IAH.Impact statement: Nurses should conduct a CSM-based intervention program to help patients with IAH improve illness perceptions.

Abstract
INTRODUCTION Older age and longer disease duration are key risk factors for hypoglycemia in patients with type 2 diabetes (T2D) who receive insulin. Previous studies have shown that insulin glargine 300 U/mL (Gla-300) improves glycemic control and reduces the risk of hypoglycemia, but whether this effect is observed in older patients switching from neutral protamine Hagedorn (NPH) insulin is unclear. METHODS In this multicenter, observational study involving patients with T2D aged ≥ 18 years with glycated hemoglobin (HbA1c) ≥ 8%, we compared the safety and effectiveness of switching from NPH insulin to Gla-300 in subgroups of patients differing by age (< 65 vs. ≥ 65 years) and duration of diabetes (≤ 13 vs. > 13 years). RESULTS A total of 469 participants were included in the study. From baseline to 6 months after switching to Gla-300, mean HbA1c decreased from 9.23% to 8.13% (p < 0.001) among patients aged ≤ 65 years (224 patients), and from 9.15% to 8.20% (p < 0.001) among those aged > 65 years (245 patients). The proportion of patients with ≥ 1 episodes of hypoglycemia decreased from 19.1% to 13.6% (p = 0.11) among those aged ≤ 65 years, and from 26.9% to 13.0% (p < 0.001) among those aged > 65 years; the reduction was significantly greater in those aged > 65 years (p = 0.001). The reduction in HbA1c was greater in those with a disease duration ≤ 13 years (p = 0.007), but the reduction in hypoglycemia was greater in those with a disease duration > 13 years (p < 0.0003). CONCLUSION The switch from NPH insulin to Gla-300 improved glycemic control in older patients with T2D and in those with a longer disease duration. Older patients with T2D and those with a longer disease duration benefited even more from the switch to Gla-300 than younger patients and those with a shorter disease duration, with significantly greater reductions in the risk of hypoglycemia.

Abstract
BACKGROUND Sarcopenia and frailty influence clinical patients' outcomes. Low alanine aminotransferase (ALT) serum activity is a surrogate marker for sarcopenia and frailty. In-hospital hypoglycemia is associated, also with worse clinical outcomes. AIM We evaluated the association between low ALT, risk of in-hospital hypoglycemia and subsequent mortality. DESIGN This was a retrospective cohort analysis. METHODS We included patients hospitalized in a tertiary hospital between 2007 and 2019. Patients' data were retrieved from their electronic medical records. RESULTS The cohort included 51 831 patients (average age 70.88). The rate of hypoglycemia was 10.8% (amongst diabetics 19.4% whereas in non-diabetics 8.3%). The rate of hypoglycemia was higher amongst patients with ALT < 10 IU/l in the whole cohort (14.3% vs. 10.4%, P < 0.001) as well as amongst diabetics (24.6% vs. 18.8%, P < 0.001). Both the overall and in-hospital mortality were higher in the low ALT group (57.7% vs. 39.1% P < 0.001 and 4.3% vs. 3.2%, P < 0.001). A propensity score matching, after which a regression model was performed, showed that patients with ALT levels < 10 IU/l had higher risk of overall mortality (HR = 1.21, CI 1.13-1.29, P < 0.001). CONCLUSIONS Low ALT values amongst hospitalized patients are associated with increased risk of in-hospital hypoglycemia and overall mortality.

Hypoglycemic and Hyperglycemic Crises Among U.S. Adults With Diabetes and End-stage Kidney Disease: Population-Based Study, 2013-2017. Diabetes Care 2022; 45:100-107. [PMID: 34740910 PMCID: PMC8753755 DOI: 10.2337/dc21-1579] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 09/27/2021] [Indexed: 02/03/2023]
Abstract
OBJECTIVE We characterized annual trends of severe hypoglycemic and hyperglycemic crises (diabetic ketoacidosis/hyperglycemic hyperosmolar state) in patients with diabetes and end-stage kidney disease (ESKD). RESEARCH DESIGN AND METHODS This was a nationwide, retrospective study of adults (≥18 years old) with diabetes/ESKD, from the United States Renal Data System registry, between 2013 and 2017. Primary outcome was annual rates of emergency department visits or hospitalizations for hypoglycemic and hyperglycemic crises, reported as number of events/1,000 person-years. Event rates and risk factors were adjusted for patient age, sex, race/ethnicity, dialysis modality, comorbidities, treatment regimen, and U.S. region. RESULTS Among 521,789 adults with diabetes/ESKD (median age 65 years [interquartile range 57-73], 56.1% male, and 46% White), overall adjusted rates of hypoglycemic and hyperglycemic crises were 53.64 and 18.24 per 1,000 person-years, respectively. For both hypoglycemia and hyperglycemia crises, respectively, the risks decreased with age and were lowest in older patients (≥75 vs. 18-44 years old: incidence rate ratio 0.35, 95% CI 0.33-0.37, and 0.03, 0.02-0.03), women (1.09, 1.06-1.12, and 1.44, 1.35-1.54), and those with smoking (1.36, 1.28-1.43, and 1.71, 1.53-1.91), substance abuse (1.27, 1.15-1.42, and 1.53, 1.23-1.9), retinopathy (1.10, 1.06-1.15, and 1.36, 1.26-1.47), and insulin therapy (vs. no therapy; 0.60, 0.59-0.63, and 0.44, 0.39-0.48). For hypoglycemia, specifically, additional risk was conferred by Black race (1.11, 1.08-1.15) and amputation history (1.20, 1.13-1.27). CONCLUSIONS In this nationwide study of patients with diabetes/ESKD, hypoglycemic crises were threefold more common than hyperglycemic crises, greatly exceeding national reports in nondialysis patients with chronic kidney disease. Young, Black, and female patients were disproportionately affected.

Abstract
INTRODUCTION There are 3.9 million people in the UK with diabetes. Sarcopenia, increased frailty and loss of independence are often unappreciated complications of diabetes. Resistance exercise shows promise in reducing these complications in older adult diabetes patients. The aim of this feasibility randomised controlled trial is to (1) characterise the physical function, cardiovascular health and the health and well-being of older adults with mild frailty with/without diabetes treated with insulin, (2) to understand the feasibility and acceptability of a 4-week resistance exercise training programme in improving these parameters for those with diabetes and (3) to test the feasibility of recruiting and randomising the diabetic participant group to a trial of resistance training. METHODS AND ANALYSIS Thirty adults aged ≥60 years with insulin-treated diabetes mellitus (type 1 or 2), and 30 without, all with mild frailty (3-4 on the Rockwood Frailty Scale) will be recruited. All will complete blood, cardiovascular and physical function testing. Only the diabetic group will then proceed into the trial itself. They will be randomised 1:1 to a 4-week semisupervised resistance training programme, designed to increase muscle mass and strength, or to usual care, defined as their regular physical activity, for 4 weeks. This group will then repeat testing. Primary outcomes include recruitment rate, attrition rate, intervention fidelity and acceptability, and adherence to the training programme. A subset of participants will be interviewed before and after the training programme to understand experiences of resistance training, impact on health and living with diabetes (where relevant) as they have aged. Analyses will include descriptive statistics and qualitative thematic analysis. ETHICS AND DISSEMINATION The North East-Newcastle and North Tyneside 2 Research Ethics Committee (20/NE/0178) approved the study. Outputs will include feasibility data to support funding applications for a future definitive trial, conference and patient and public involvement presentations, and peer-reviewed publications. TRIAL REGISTRATION NUMBER ISRCTN13193281.

Abstract
AIM The objective of the CRASH (Conversations and Reactions Around Severe Hypoglycemia) survey was to further our understanding of the characteristics, experience, behavior and conversations with healthcare professionals (HCPs) of persons with diabetes (PWD) receiving insulin, and of their caregivers (CGs), concerning hypoglycemia requiring external assistance (severe hypoglycemic events [SHEs]). METHODS CRASH was an online cross-sectional survey conducted across eight countries. The PWDs with self-reported type 1 (T1D) or insulin-treated type 2 (T2D) diabetes were aged ≥18 years and had experienced one or more SHEs in past the 3 years; CGs were non-medical professionals aged ≥18 years, caring for a PWD meeting all the above criteria except for PWD age (≥4 rather than ≥18 years). The present report is a descriptive analysis of data from France. RESULTS Among PWDs who had ever discussed SHEs with an HCP, 38.9% of T1D PWDs and 50.0% of T2D PWDs reported that SHEs were discussed at every consultation; 26.3% and 8.8% respectively had not discussed the most recent SHE with an HCP. 35.7% of T1D PWDs and 53.8% of T2D PWDs reported that glucagon was not available to them at the time of their most recent SHE. Only 16.9% of T1D PWDs and 6.5% of T2D PWDs who had discussed their most recent SHE with an HCP reported that the HCP recommended obtaining a glucagon kit or asked them to confirm that they already had one. High proportions of PWDs and CGs reported that the most recent SHE had made them feel unprepared, scared and helpless and had affected mood, emotional state and activities. CONCLUSION CRASH survey data from France identify a need for greater discussion about SHEs between HCPs and PWDs and their CGs, and reveal gaps in the diabetes education of PWDs and CGs.

Abstract
INTRODUCTION Despite considerable progress in diabetes treatment, prevalence of nocturnal hypoglycemia in type 1 diabetes mellitus (T1DM) and advanced insulin treated type 2 diabetes mellitus (T2DM) remains high. AREAS COVERED The present manuscript describes the prevalence of night-time hypoglycemia as reported in observational and randomized controlled trials. Factors that affect the risk of hypoglycemia are highlighted. The authors also describe impaired awareness of hypoglycemia and available preventive methods. EXPERT OPINION Prevention of nocturnal hypoglycemia includes behavioral, dietary and pharmacologic interventions. The most recent development with the lowest rate of hypoglycemia is sensor-augmented pumps with predictive low glucose suspend technology. These pumps combine continuous subcutaneous insulin infusion with continuous glucose monitoring and use various algorithms to predict and stop hypoglycemia before it develops.

Abstract
INTRODUCTION Adherence to treatment and hypoglycemia awareness are strongly linked to glycemic control and hypoglycemia risk in people with type 2 diabetes mellitus (T2DM). Community pharmacies are suitable facilities to detect these conditions, and should be involved in the strategies to minimize the associated risks and burden. RESEARCH DESIGN AND METHODS This cross-sectional study conducted at community pharmacies across Spain assessed the prevalence of low adherence to antidiabetic treatments, the frequency of impaired hypoglycemia awareness, and their predictive factors. Adherence was measured with the 8-item Morisky Medication Adherence Scale (MMAS-8) and electronic records of dispensed treatments. The Clarke questionnaire was used to assess impaired hypoglycemia awareness. Healthcare counseling provided in the pharmacy was collected. RESULTS Seventy-nine pharmacists and 618 subjects with T2DM participated in the study. Mean age in the overall T2DM population was 67 years, being the majority (69%) pensioners. Adherence was high in 41% of participants, medium in 35%, and low in 24% according to the MMAS-8. Impaired hypoglycemia awareness was observed in 25% of participants. Main determinants of low adherence were the level of education, the number of treatments per patient, hypoglycemia awareness, and the type of pharmacy. Predictive factors of impaired hypoglycemia awareness were the level of education, information on diabetes-related complications, adherence levels, and the type of pharmacy. The proportion of participants who had healthcare counseling was 71% in the overall population and 100% in subjects with impaired hypoglycemia awareness and low adherence. Healthcare counseling comprised diabetes education (69%), pharmacotherapeutic assessment (20%), and physician referrals (11%). CONCLUSION Lack of adherence to antidiabetic treatments and impaired hypoglycemia awareness are frequent and correlate in T2DM. Community pharmacies can detect these conditions and should have an active role in the design of strategies to minimize them.

Abstract
One hundred years after its discovery, insulin remains the life-saving therapy for many patients with diabetes. It has been a 100-years-old success story thanks to the fact that insulin therapy has continuously integrated the knowledge developed over a century. In 1982, insulin becomes the first therapeutic protein to be produced using recombinant DNA technology. The first "mini" insulin pump and the first insulin pen become available in 1983 and 1985, respectively. In 1996, the first generation of insulin analogues were produced. In 1999, the first continuous glucose-monitoring device for reading interstitial glucose was approved by the FDA. In 2010s, the ultra-long action insulins were introduced. An equally exciting story developed in parallel. In 1966. Kelly et al. performed the first clinical pancreas transplant at the University of Minnesota, and now it is a well-established clinical option. First successful islet transplantations in humans were obtained in the late 1980s and 1990s. Their ability to consistently re-establish the endogenous insulin secretion was obtained in 2000s. More recently, the possibility to generate large numbers of functional human β cells from pluripotent stem cells was demonstrated, and the first clinical trial using stem cell-derived insulin producing cell was started in 2014. This year, the discovery of this life-saving hormone turns 100 years. This provides a unique opportunity not only to celebrate this extraordinary success story, but also to reflect on the limits of insulin therapy and renew the commitment of the scientific community to an insulin free world for our patients.

Abstract
AIM To examine blood glucose measurements recorded as part of the diabetes protocol operated by the UK, Ireland and Austria, which allows commercial airline pilots with insulin-treated diabetes to fly. METHODS An observational study was conducted in pilots with insulin-treated diabetes, granted medical certification to fly commercial or noncommercial aircraft, who recorded pre-flight and hourly in-flight blood glucose measurements. These values were correlated to a traffic light system (green 5.0 to 15.0 mmol/L; amber 4.0 to 4.9 mmol/L and 15.1 to 20.0 mmol/L; and red <4.0 mmol/L or >20.0 mmol/L) and studied for trends in glucose concentrations, time course within flight and any consequences. Pilot demographics were also analysed. RESULTS Forty-four pilots (90%) recorded one or more blood glucose value outside the green range during the 7 years of the study. Pilot age, diabetes type and duration, and follow-up period were comparable among subgroups, and mean glycated haemoglobin did not differ before and after certification in a way which would indicate poorer glycaemic control in any subgroup. A total of 892 blood glucose values (2.31%) were outside the green range, with half reported in-flight at various time intervals. There were 48 (0.12%) low red range values recorded, 14 (0.04%) of which occurred in-flight; all but four were restored to within the green range by the time of the next measurement. Appropriate corrective action was taken for all out-of-range values, with no reports of pilot incapacitation from any cause. CONCLUSIONS The traffic light system appears effective in identifying and reducing the frequency and severity of out-of-range values.

Abstract
AIMS We aimed to investigate the effect of an intervention in which ambulance personnel provided advice supported by a booklet-'Hypos can strike twice'-issued following a hypoglycaemic event to prevent future ambulance attendances. METHODS We used a non-randomised stepped wedge-controlled design. The intervention was introduced at different times (steps) in different areas (clusters) of operation within East Midlands Ambulance Service NHS Trust (EMAS). During the first step (T0), no clusters were exposed to the intervention, and during the last step (T3), all clusters were exposed. Data were analysed using a general linear mixed model (GLMM) and an interrupted-time series analysis (ITSA). RESULTS The study included 4825 patients (mean age 65.42 years, SD 19.42; 2,166 females) experiencing hypoglycaemic events attended by EMAS. GLMM indicated a reduction in the number of unsuccessful attendances (i.e., attendance followed by a repeat attendance) in the final step of the intervention when compared to the first (odds ratio OR: 0.50, 95%CI: 0.33-0.76, p = 0.001). ITSA indicated a significant decrease in repeat ambulance attendances for hypoglycaemia-relative to the pre-intervention trend (p = 0.008). Furthermore, the hypoglycaemia care bundle was delivered in 66% of attendances during the intervention period, demonstrating a significant level of practice change (p < 0.001). CONCLUSION The 'Hypos can strike twice' intervention had a positive effect on reducing numbers of repeat attendances for hypoglycaemia and in achieving the care bundle. The study supports the use of information booklets by ambulance clinicians to prevent future attendances for recurrent hypoglycaemic events.

Abstract
INTRODUCTION This study aimed to assess the association between fasting serum C-peptide levels and the presence of impaired awareness of hypoglycemia (IAH) in people with type 1 diabetes. RESEARCH DESIGN AND METHODS We performed a cross-sectional study among 509 individuals with type 1 diabetes (diabetes duration 5-65 years). Extensive clinical data and fasting serum C-peptide concentrations were collected and related to the presence or absence of IAH, which was evaluated using the validated Dutch version of the Clarke questionnaire. A multivariable logistic regression model was constructed to investigate the association of C-peptide and other clinical variables with IAH. RESULTS In 129 (25%) individuals, residual C-peptide secretion was detected, while 75 (15%) individuals reported IAH. The median (IQR) C-peptide concentration among all participants was 0.0 (0.0-3.9) pmol/L. The prevalence of severe hypoglycemia was lower in people with demonstrable C-peptide versus those with absent C-peptide (30% vs 41%, p=0.025). Individuals with IAH were older, had longer diabetes duration, more frequently had macrovascular and microvascular complications, and more often used antihypertensive drugs, antiplatelet agents and cholesterol-lowering medication. There was a strong association between IAH and having a severe hypoglycemia in the preceding year. In multivariable regression analysis, residual C-peptide, either continuously or dichotomous, was associated with lower prevalence of IAH (p=0.040-0.042), while age at diabetes onset (p=0.001), presence of microvascular complications (p=0.003) and body mass index (BMI) (p=0.003) were also independently associated with the presence of IAH. CONCLUSIONS Higher BMI, the presence of microvascular complications and higher age at diabetes onset were independent risk factors for IAH in people with type 1 diabetes, while residual C-peptide secretion was associated with lower risk of this complication.

Abstract
AIMS OF THE STUDY The minimum therapeutic goal regarding metabolic control for people with diabetes mellitus is the "absence of symptoms of hyperglycemia." However, it is uncertain whether a level of HbA1c can be defined that guarantees the absence of these symptoms. The aim was to define an HbA1c threshold above which most patients show hyperglycemic symptoms. METHODS In a multicenter cross-sectional study, 137 patients with type 1 and 285 with type 2 diabetes were asked about their symptoms during periods of hyperglycemia with a standardized questionnaire. Seventeen symptoms of hyperglycemia were summarized to the total hyperglycemia symptom score (THSS; min. 0; max. 68). The answers could be given according to the frequency and intensity in the last 4 - 6 weeks. RESULTS The HbA1c threshold above which most patients showed hyperglycemic symptoms was 10.05% for patients with diabetes type 1 and 8.9%. for patients with type 2. Most confidence was reached on the symptoms of frequent urination" and "tiredness." The mean THSS was 19.4 (±9.0) and showed a positive correlation with age (r=0.167; p<0.001) and HbA1c (r=0.254; p<0.001). CONCLUSIONS We identified an HbA1c threshold above which most patients show symptoms of hyperglycemia. In the treatment of people with diabetes mellitus, a safety margin to this threshold should be maintained to preserve well-being and avoid distress. However, since hyperglycemia symptoms are subject to many influencing factors, an adjustment of the therapy-both intensification and de-intensification-should always be carried out in combination with the requested hyperglycemia symptoms and HbA1c value.

[PMID: 34116789 DOI: 10.1016/j.eprac.2021.04.008] [Citation(s) in RCA: 95] [Impact Index Per Article: 31.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 04/16/2021] [Accepted: 04/19/2021] [Indexed: 02/08/2023]
Abstract
OBJECTIVE To provide evidence-based recommendations regarding the use of advanced technology in the management of persons with diabetes mellitus to clinicians, diabetes-care teams, health care professionals, and other stakeholders. METHODS The American Association of Clinical Endocrinology (AACE) conducted literature searches for relevant articles published from 2012 to 2021. A task force of medical experts developed evidence-based guideline recommendations based on a review of clinical evidence, expertise, and informal consensus, according to established AACE protocol for guideline development. MAIN OUTCOME MEASURES Primary outcomes of interest included hemoglobin A1C, rates and severity of hypoglycemia, time in range, time above range, and time below range. RESULTS This guideline includes 37 evidence-based clinical practice recommendations for advanced diabetes technology and contains 357 citations that inform the evidence base. RECOMMENDATIONS Evidence-based recommendations were developed regarding the efficacy and safety of devices for the management of persons with diabetes mellitus, metrics used to aide with the assessment of advanced diabetes technology, and standards for the implementation of this technology. CONCLUSIONS Advanced diabetes technology can assist persons with diabetes to safely and effectively achieve glycemic targets, improve quality of life, add greater convenience, potentially reduce burden of care, and offer a personalized approach to self-management. Furthermore, diabetes technology can improve the efficiency and effectiveness of clinical decision-making. Successful integration of these technologies into care requires knowledge about the functionality of devices in this rapidly changing field. This information will allow health care professionals to provide necessary education and training to persons accessing these treatments and have the required expertise to interpret data and make appropriate treatment adjustments.

Abstract
Hypoglycaemia (blood glucose concentration below the normal range) has been recognised as a complication of insulin treatment from the very first days of the discovery of insulin, and remains a major concern for people with diabetes, their families and healthcare professionals today. Acute hypoglycaemia stimulates a stress response that acts to restore circulating glucose, but plasma glucose concentrations can still fall too low to sustain normal brain function and cardiac rhythm. There are long-term consequences of recurrent hypoglycaemia, which are still not fully understood. This paper reviews our current understanding of the acute and cumulative consequences of hypoglycaemia in insulin-treated diabetes.

Abstract
ZusammenfassungIn der Behandlung des Typ-1-Diabetes ist die Therapie mit Insulin auch 100 Jahre nach seiner Entdeckung weiterhin eine lebensnotwendige Therapie. Der pharmakologische Fortschritt hat die Behandlung erheblich erleichtert und nähert sich der physiologischen Insulin-Sekretion zunehmend an. In der Behandlung des Typ-2-Diabetes hingegen ist die Insulin-Therapie bei den meisten Patienten zunächst nicht notwendig. Lebensstil-Interventionen und moderne Nicht-Insulin Antidiabetika können häufig zu einer lang andauernden Kontrolle der Erkrankung führen. Die Heterogenität des Typ-2-Diabetes führt jedoch dazu, dass einige Patienten früh von einer Insulin-Therapie profitieren. Auch beim Typ-2-Diabetes können moderne Insulin Präparate die Insulin-Behandlung deutlich erleichtern, auch in Kombination mit anderen Antidiabetika. Einleitung und Begleitung einer Insulin-Therapie gehören somit weiterhin zu den Kernaufgaben der Diabetologie.

Abstract
AIMS To develop a simple hypoglycemic prediction model to evaluate the risk of hypoglycemia during hospitalization in patients with type 2 diabetes treated with intensive insulin therapy. METHODS We performed a cross-sectional chart review study utilizing the electronic database of the Third Affiliated Hospital of Sun Yat-sen University, and included 257 patients with type 2 diabetes undergoing intensive insulin therapy in the Department of Endocrinology and Metabolism. Logistic regression analysis was used to derive the clinical prediction rule with hypoglycemia (blood glucose ≤ 3.9 mmol/L) as the main result, and internal verification was performed. RESULTS In the derivation cohort, the incidence of hypoglycemia was 51%. The final model selected included three variables: fasting insulin, fasting blood glucose, and total treatment time. The area under the curve (AUC) of this model was 0.666 (95% CI: 0.594-0.738, P < 0.001). CONCLUSIONS The model's hypoglycemia prediction and the actual occurrence are in good agreement. The variable data was easy to obtain and the evaluation method was simple, which could provide a reference for the prevention and treatment of hypoglycemia and screen patients with a high risk of hypoglycemia.
