Abstract
In glucose-deprived conditions, ketone bodies are produced by the liver mitochondria, through the catabolism of fatty acids, and are used peripherally, as an alternative energy source. Ketones are produced in the body under normal conditions, including during pregnancy and the neonatal period, when following a ketogenic diet (KD), fasting, or exercising. Additionally, ketone synthesis is also augmented under pathological conditions, including cases of diabetic ketoacidosis (DKA), alcoholism, and several metabolic disorders. Nonetheless, diet is the main regulator of total body ketone concentrations. The KDs are mimicking the fasting state, altering the default metabolism towards the use of ketones as the primary fuel source. Recently, KD has gained recognition as a medical nutrition therapy for a plethora of metabolic conditions, including obesity and diabetes mellitus (DM). The present review aims to discuss the role of ketones, KDs, ketonemia, and ketonuria in DM, presenting all the available new evidence in a comprehensive manner.

[PMID: 35881330 PMCID: PMC9439977 DOI: 10.1007/s40272-022-00520-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 06/14/2022] [Indexed: 11/14/2022]
Abstract
The pharmacokinetic and pharmacodynamic properties of the second-generation basal insulin glargine 300 Units/mL (Gla-300) may be of benefit in the treatment of type 1 diabetes mellitus (T1DM). Gla-300 provides a stable and sustained time-action profile, which is associated with glycaemic control and flexible dosing schedule. This review summarises the available evidence on the safety and efficacy of Gla-300 in children and adolescents with T1DM. Gla-300 is as effective as the first-generation basal insulin glargine 100 Units/mL (Gla-100), a standard of care for patients with diabetes in reducing HbA1c, and shows a lower risk of severe hypoglycaemia and hyperglycaemia in children and adolescents with T1DM. However, Gla-300 and Gla-100 are not bioequivalent and are not directly interchangeable. Real-world studies on patients aged 6-17 years are limited. To date, only one small study assessed the effectiveness and safety of Gla-300 versus Gla-100 in newly diagnosed T1DM paediatric patients, confirming the treatment safety and effectiveness of Gla-300 in clinical practice. Gla-300 is a longer-acting basal insulin alternative in the management of children (aged ≥ 6 years) and adolescents with T1DM.

Diabetes Care 2021; 44:125-132. [PMID: 33444161 DOI: 10.2337/dc20-1033] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Accepted: 10/12/2020] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To prove equivalence of individual, clinically titrated basal insulin doses of glargine 300 units ⋅ mL-1 (Gla-300) and degludec 100 units ⋅ mL-1 (Deg-100) under steady state conditions in a single-blind, randomized, crossover study, on the glucose pharmacodynamics (PD) in people with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS Subjects with T1D (N = 22, 11 men, age 44.3 ± 12.4 years, disease duration 25.5 ± 11.7 years, A1C 7.07 ± 0.63% [53.7 ± 6.9 mmol ⋅ mL-1], BMI 22.5 ± 2.7 kg · m-2), naïve to Gla-300 and Deg-100, underwent 24-h euglycemic clamps with individual clinical doses of Gla-300 (0.34 ± 0.08 units ⋅ kg-1) and Deg-100 (0.26 ± 0.06 units ⋅ kg-1), dosing at 2000 h, after 3 months of optimal titration of basal (and bolus) insulin. RESULTS At the end of 3 months, Gla-300 and Deg-100 reduced slightly and, similarly, A1C versus baseline. Clamp average plasma glucose (0-24 h) was euglycemic with both insulins. The area under curve of glucose infused (AUC-GIR[0-24 h]) was equivalent for the two insulins (ratio 1.04, 90% CI 0.91-1.18). Suppression of endogenous glucose production, free fatty acids, glycerol, and β-hydroxybutyrate was 9%, 14%, 14%, and 18% greater, respectively, with Gla-300 compared with Deg-100 during the first 12 h, while glucagon suppression was no different. Relative within-day PD variability was 23% lower with Gla-300 versus Deg-100 (ratio 0.77, 90% CI 0.63-0.92). CONCLUSIONS In T1D, individualized, clinically titrated doses of Gla-300 and Deg-100 at steady state result in similar glycemic control and PD equivalence during euglycemic clamps. Clinical doses of Gla-300 compared with Deg-100 are higher and associated with quite similar even 24-h distribution of PD and antilipolytic effects.

Diabetes Obes Metab 2021; 23:166-174. [PMID: 33001554 PMCID: PMC7821234 DOI: 10.1111/dom.14212] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 09/25/2020] [Accepted: 09/27/2020] [Indexed: 12/25/2022]
Abstract
AIMS Insulin glargine 300 U/mL (Gla-300) contains the same units versus glargine 100 U/mL (Gla-100) in three-fold lower volume, and higher subcutaneous (SC) doses are required in people with diabetes. To investigate blood glucose (BG) lowering potency, Gla-300 and Gla-100 were compared after intravenous (IV, for 4 h) and SC (for 24 h) injection in healthy Beagle dogs. MATERIALS AND METHODS The dose of 0.15 U/kg Gla-300 and Gla-100 was injected IV in 12 dogs. BG, C-peptide, glucagon and the active metabolite 21A-Gly-human insulin (M1; liquid chromatography-tandem mass spectrometry method) were measured. Twelve other dogs were studied after SC injection of 0.3 U/kg Gla-300 and Gla-100. RESULTS After IV injection, Gla-300 and Gla-100 were equally potent [BG_AUC0-4 h ratio 1.01 (95% confidence interval, 0.94; 1.09)]. After SC injection, BG decreased slower and less with Gla-300. Similar metabolism of Gla-300 and Gla-100 to M1 occurred with IV dosing [M1_AUC0-1 h ratio 0.99 (95% confidence interval, 0.82; 1.22)], but with SC dosing M1_Cmax and AUC0-24h were 44% and 17% lower; mean residency time and bioavailability were 32% longer and 50% lower, with Gla-300. CONCLUSIONS IV Gla-300 and Gla-100 have the equivalent of BG-lowering potency and M1 metabolism. SC Gla-300 has lower M1 bioavailability with a reduced BG-lowering effect and need for greater doses versus Gla-100.

Diabetes Obes Metab 2020; 22:1880-1885.

Abstract
Severe hypoglycaemia (SH) remains a challenge to people with type 1 diabetes (T1DM), and new-generation basal insulins may improve patient outcomes. This post hoc meta-analysis explored the risk of SH with insulin glargine 300 U/mL (Gla-300) versus glargine 100 U/mL (Gla-100) in a pooled population with T1DM from three randomized, multicentre, 6-month similarly designed phase 3 trials: EDITION 4, EDITION JP 1 and EDITION JUNIOR. Endpoints included incidence and time to first occurrence of SH. Among 629 and 626 participants randomized to Gla-300 and Gla-100, respectively, glycated haemoglobin reductions were similar. Fewer participants experienced ≥1 SH event with Gla-300 (6.2%) than with Gla-100 (9.3%). From baseline to month 6, the risk of a first SH event was lower with Gla-300: hazard ratio 0.65 [95% confidence interval (CI) 0.44-0.98; stratified log-rank test P = 0.038]. SH event rates were numerically lower with Gla-300 versus Gla-100 from baseline to month 6 [relative risk (RR) 0.80 (95% CI 0.49-1.29); P = 0.356] and baseline to week 8 [RR 0.73 (95% CI 0.37-1.44); P = 0.369]. Thus, Gla-300 demonstrated similar glycaemic control with lower risk of SH versus Gla-100, particularly during the titration period.

Comparable efficacy with similarly low risk of hypoglycaemia in patient- vs physician-managed basal insulin initiation and titration in insulin-naïve type 2 diabetic subjects: The Italian Titration Approach Study. Diabetes Metab Res Rev 2020; 36:e3304.

Abstract
AIMS People with uncontrolled type 2 diabetes (T2DM) often delay initiating and titrating basal insulin. Patient-managed titration may reduce such deferral. The Italian Titration Approach Study (ITAS) compared the efficacy and safety of insulin glargine 300 U/mL (Gla-300) initiation and titration using patient- (nurse-supported) or physician-management in insulin-naïve patients with uncontrolled T2DM. MATERIALS AND METHODS ITAS was a multicentre, phase IV, 24-week, open-label, randomized (1:1), parallel-group study. Insulin-naïve adults with T2DM for ≥1 year with poor metabolic control initiated Gla-300 after discontinuation of SU/glinides, and were randomized to self-titrate insulin dose (nurse-assisted) or have it done by the physician. The primary endpoint was change in HbA1c . Secondary outcomes included hypoglycaemia incidence and rate, change in fasting self-monitored plasma glucose, patient-reported outcomes (PROs), and adverse events. RESULTS Three hundred and fifty five participants were included in the intention-to-treat population. At Week 24, HbA1c reduction from baseline was non-inferior in patient- vs physician-managed arms [least squares mean (LSM) change (SE): -1.60% (0.06) vs -1.49% (0.06), respectively; LSM difference: -0.11% (95% CI: -0.26 to 0.04)]. The incidence and rates of hypoglycaemia were similarly low in both arms: relative risk of confirmed and/or severe nocturnal (00:00-05:59 hours) hypoglycaemia was 0.77 (95% CI: 0.27 to 2.18). No differences were observed for improvement in PROs. No safety concerns were reported. CONCLUSIONS In the T2DM insulin-naïve, SU/glinides discontinued population, patient-managed (nurse-assisted) titration of Gla-300 may be a suitable option as it provides improved glycaemic control with low risk of hypoglycaemia, similar to physician-managed titration.

Abstract
AIMS Chronic kidney disease (CKD) challenges diabetes management and is associated with increased cardiovascular morbidity and mortality. We examined whether clinical outcomes with insulin glargine 300 U/mL (Gla-300) and insulin degludec 100 U/mL (IDeg-100) are affected by renal function in a prespecified subgroup analysis from the BRIGHT trial. MATERIALS AND METHODS BRIGHT (NCT02738151) was a multicentre, open-label, randomized, active-controlled, two-arm, parallel-group, 24-week study in insulin-naïve uncontrolled type 2 diabetes (T2D). Participants were randomized 1:1 to evening Gla-300 (n = 466) or IDeg-100 (n = 463) and stratified based on baseline estimated glomerular filtration rate (eGFR) for this analysis. RESULTS Heterogeneity of treatment effect across renal function subgroups was observed (P = .02), reflecting a greater mean glycated haemoglobin (HbA1c) reduction from baseline to week 24 with Gla-300 versus IDeg-100 in the eGFR <60 mL/min/1.73 m2 subgroup (least squares mean difference: -0.43% [95% confidence interval: -0.74% to -0.12%]), while there were no differences in hypoglycaemia incidence or rates over 24 weeks in that subgroup. HbA1c reductions were similar between treatments in the other eGFR subgroups. However, heterogeneity was observed for annualized rates of anytime (24 hours) or nocturnal (00:00-05:59 hours) confirmed hypoglycaemia (≤70 mg/dL [≤3.9 mmol/L]) over 24 weeks showing less hypoglycaemia with Gla-300 versus IDeg-100 in the ≥90 mL/min/1.73 m2 . CONCLUSIONS Kidney function seems to affect the glucose-lowering effects of Gla-300 versus IDeg-100 in insulin-naïve T2D. Greater HbA1c reductions with Gla-300 without increase in hypoglycaemia risk, were observed in patients with eGFR <60 mL/min/1.73 m2 .
