Background: Patients with Type 2 Diabetes Mellitus (T2DM) may develop hypoglycemia as an adverse effect of insulin therapy. Hypoglycemia has dangerous consequences that result from neuroglycopenia and hypersecretion of counter-regulatory hormones. Patients who recognize early symptoms of hypoglycemia can initiate self-treatment and rectify the situation. Impaired Awareness of Hypoglycemia (IAH) predisposes patients to severe hypoglycemia and unconsciousness. Objective: To assess the prevalence of IAH, the intensity of hypoglycaemic symptoms, the frequency of severe hypoglycemia and factors associated with IAH in patients with insulin-treated T2DM. Methods: This is a cross-sectional study that used Clarke's and Gold's surveys to assess IAH and Edinburgh survey to assess the intensity of hypoglycemic symptoms in patients with insulin-treated T2DM (n= 388). The frequency of hypoglycemia and other data were collected by self-reporting or from medical records. Results: The prevalence (95% confidence interval) of IAH was 17.01% (13.27%-20.75%) as determined by Clarke’s method and 5.93% (3.58-8.28) by Gold’s method (Odds= 3.25, p-value<0.00001). Drowsiness, hunger, sweating, tiredness, trembling and weakness, were the most intense hypoglycaemic symptoms, and 6.19% of participants reported at least one episode of severe hypoglycaemia within the past year. Regardless of classification method used, IAH is not dependent on age, gender, duration of T2DM or duration of insulin therapy (p-values>0.05). Instead, IAH is positively associated with frequency of hypoglycaemia during the previous six months (p-value<0.05) and development of severe hypoglycaemia within the past year (p-value <0.05). Conclusion: This study highlights large variability in IAH depending on the method used for assessment. Increased hypoglycaemia frequency may increase the prevalence of IAH and thus the development of severe hypoglycemia

ObjectivePeople with type 2 diabetes on insulin are at risk for hypoglycemia. Recurrent hypoglycemia can cause impaired awareness of hypoglycemia (IAH), and increase the risk for severe hypoglycemia. The aim of this study was to assess the prevalence and determinants of self-reported IAH and severe hypoglycemia in a Dutch nationwide cohort of people with insulin-treated type 2 diabetes.Research design and methodsObservational study of The Dutch Diabetes Pearl, a cohort of people with type 2 diabetes treated in primary, secondary and tertiary diabetes care centers. The presence of IAH and the occurrence of severe hypoglycemia in the past year, defined as an event requiring external help to recover, were assessed using the validated Dutch version of the Clarke questionnaire. In addition, clinical variables were collected including age, diabetes duration, hemoglobin A1c, ethnicity and education.Results2350 people with type 2 diabetes on insulin were included: 59.1% men, mean age 61.1±10.4 years, mean diabetes duration 14.8±9.2 years and 79.5% on basal-bolus therapy. A total of 229 patients (9.7%) were classified as having IAH and 742 patients (31.6%) reported severe hypoglycemia. Increased odds for IAH were found with complex insulin regimens and lower odds with having a partner and body mass index ≥30 kg/m2. Severe hypoglycemia was associated with complex insulin regimens, non-Caucasian ethnicity and use of psychoactive drugs, and inversely with metformin use.ConclusionsIn this nationwide cohort, almost one out of ten people with type 2 diabetes on insulin had IAH and >30% had a history of severe hypoglycemia in the past year.

ObjectivesHypoglycemia is a common side effect of insulin therapy in type 1 and type 2 diabetes. Limited data exist on the frequency of hypoglycemic events in type 2 diabetic patients in Turkey. Our study investigated self-reported hypoglycemic events and awareness of hypoglycemia in Turkish patients with type 2 diabetes.MethodsPeople with type 2 diabetes older than 18 years of age were recruited from the two university hospital diabetes clinics. The frequency and severity of hypoglycemia and awareness of hypoglycemia during the preceding year were determinated using questionnaires by the face-to-face interview method.ResultsIn this study of 187 patients with type 2 diabetes, 83.4% had impaired awareness of their hypoglycemia, and 62% reported that they had missed some of the symptoms of hypoglycemia. Of the patients reporting hypoglycemic symptoms and severity level, 84.1% experienced mild hypoglycemia, 60% moderate, and 15.5% severe hypoglycemia in the past year. No significant association was made between hypoglycemia awareness and age, body-mass index (BMI), years of diabetes, dose of insulin, duration of insulin use, number of meals, or amount of snacking. A significant correlation was found between A1c levels and hypoglycemia awareness and severity of hypoglycemia. A significant correlation was found between dose of insulin, amount of snacking, and severity of hypoglycemia. No significant association was made between severity of hypoglycemia and age, BMI, years of diabetes, duration of insulin use, or the number of meals. However, the group with severe hypoglycemia had diabetes longer, and the average daily dose of insulin use was higher than in other groups.ConclusionsAccording to the study results, the percentage of patients with impaired awareness of hypoglycemia is high, and 62% of patients reported that they had missed some of the symptoms of hypoglycemia in type 2 diabetes. In addition, the percentage of severe hypoglycemic events is not low. Impaired awareness of hypoglycemia is a major risk factor for severe hypoglycemic events. Patients should be educated about the danger of hypoglycemia. Education should be improved, and a determined attempt should be made to eradicate the problem.

Abstract Purpose To assess quality of life, glycemic control, and safety/tolerability associated with liraglutide versus insulin initiation in patients with type 2 diabetes in Germany. Methods Liraglutide/insulin-naïve adults with type 2 diabetes and inadequate glycemic control despite using oral antidiabetic medication were assigned to liraglutide (≤1.8 mg daily; n=878) or any insulin (n=382) according to the treating physician’s decision and followed for 52 weeks. The primary objective was to evaluate Audit of Diabetes-Dependent Quality of Life (ADDQoL) scores. Results At baseline, the liraglutide group was younger and had shorter type 2 diabetes duration, lower glycated hemoglobin (HbA1c), higher body mass index, and a lower prevalence of certain diabetes-related complications than the insulin group (all p<0.05). ADDQoL average weighted impact scores improved numerically in both groups from baseline to 52 weeks (mean difference [95% confidence interval], liraglutide vs. insulin: 0.159 [−0.023;0.340]; not significant). Changes in general wellbeing and five ADDQoL domains significantly favored liraglutide (remaining 14 domains, not significant). HbA1c reductions were greater with insulin than liraglutide (−2.0% vs. −1.2%; p<0.01); however, mean HbA1c after 52 weeks was 7.2% in both groups. Compared with insulin, liraglutide significantly decreased body mass index (−1.54 kg/m2 vs. +0.27 kg/m2; p<0.001), systolic blood pressure (−5.03 mmHg vs. −1.03 mmHg; p<0.01) and non-severe hypoglycemia (0.85% vs. 4.55% at 52 weeks; p<0.01). Adverse drug reactions were reported for<3% of patients in both groups. Conclusions Liraglutide improved certain ADDQoL components and reduced body mass index, systolic blood pressure, and non-severe hypoglycemia versus insulin. Both treatments improved glycemic control.

Abstract Aims/Hypotheses: The aims of this study were to determine whether the angiotensin-converting enzyme (ACE) gene I/D polymorphisms independently predict severe hypoglycemia in community-dwelling type 2 patients. Methods: Six hundred two patients who were ACE genotyped at baseline and assessed in 1998 were followed up to the end of June 2006. Severe hypoglycemia was defined as that requiring documented health service use as the primary diagnosis. Cox proportional hazards modeling was used to determine the predictors of first episode and zero-inflated negative binomial regression modeling identified predictors of frequency. Results: Forty-nine patients (8.1%) experienced 63 episodes of severe hypoglycemia. After adjusting for previously identified significant independent predictors of time to first episode, both ACE DD genotype and ACE inhibitor therapy, but not their interaction, added to the model [hazard ratio (95% confidence interval): 2.34 (1.29–4.26), P = 0.006, and 1.77 (0.99–3.13), P = 0.052, respectively]. Similarly, after adjusting for previously identified risk factors for multiple episodes of severe hypoglycemia, ACE DD genotype was independently associated with increased risk [incidence relative risk (95% confidence interval): 1.80 (1.00–3.24), P = 0.050]. Conclusions/Interpretation: ACE DD genotype is associated with an increased the risk of the first episode of severe hypoglycemia and its subsequent frequency approximately 2-fold in well-characterized patients with type 2 diabetes. Consistent with previous case-control studies, ACE inhibitor therapy was a weak predictor of severe hypoglycemia. ACE I/D genotyping might provide useful adjunctive prognostic information when intensive glycemic control measures are contemplated.

Abstract We conducted a 1:1 propensity score-matched retrospective cohort study of 70,826 patients with type 2 diabetes (mean age, 71.4 years [standard deviation, 5.0]) initiating a SGLT2i or a second-generation sulfonylurea in Medicare data. We estimated HRs (95% CIs) for a composite cardiovascular endpoint and severe hypoglycemia comparing the two treatments in the entire population and by the CFI-based frailty subgroups. Compared with sulfonylureas, SGLT2is were associated with lower rates of the composite cardiovascular endpoint (HR, 0.68 [95% CI, 0.62-0.75]) and severe hypoglycemia (0.43 [0.35-0.53]) over a mean follow-up of 9.5 months. The lower rate of composite cardiovascular endpoint for SGLT2i vs sulfonylureas was observed in pre-frail (0.68 [0.61-0.77]) and frail (0.64 [0.53-0.77]) subgroups, but not in non-frail subgroup (0.95 [0.59-1.54]). The rate of severe hypoglycemia was consistently lower for SGLT2i vs sulfonylureas across frailty subgroups (non-frail, 0.37 [0.12-1.16]; pre-frail, 0.45 [0.35-0.59]; frail, 0.40 [0.28-0.58]).
