Use of capillary ketones monitoring in treatment of mild ketotic crisis in people with ketosis-prone atypical diabetes

This study was carried out to assess the potential reduction in duration of intensive diabetic ketoacidosis treatment in adults with ketosis-prone atypical diabetes (KPD) when using capillary versus urinary ketones. In this cross-sectional study, we included 20 people with KPD presented at the National Obesity Center of the Yaoundé Central Hospital with hyperglycemic decompensation (random capillary glucose ≥13 mmol/L) and significant ketosis (ketonuria≥++) requiring intensive insulin treatment. In all subjects, intensive insulin treatment was initiated at 10 UI per hour with simultaneous measurement of capillary beta-hydroxybutyrate and ketonuria every 2 hours until disappearance of ketonuria. Time-to-disappearance of urine ketones was compared with the time-to-normalization of capillary β-hydroxybutyrate concentrations. Subjects were aged 46±13 years with a median duration of diabetes of 1.5 (IQR: 0–2.5) years. On admission, the mean blood glucose was 22.8±5 mmol/L and capillary ketones level was 2.9±2.7 mmol/L. The median time-to-disappearance of ketonuria was 5 (IQR: 3–8) hours compared with the time-to-normalization of capillary β-hydroxybutyrate of 4 (IQR: 2–6) hours, p=0.0002. The absolute difference in time-to-normalization of ketonuria versus ketonemia was 2 (IQR: 1–3) hours and the relative time reduction of treatment was 32.5%±18.0%. Our results suggested that the use of capillary ketones versus ketonuria would allow a significant reduction in duration of intensive insulin treatment by one third in people with KPD.

Cost-effectiveness Analysis of a Flash Glucose Monitoring System for Patients with Type 1 Diabetes Receiving Intensive Insulin Treatment in Sweden

Flash glucose monitoring – an alternative to traditional self-monitoring of blood glucose (SMBG) – prevents hypoglycaemic events without impacting glycated haemoglobin (HbA1c).21Given the potential benefits, this study assessed the cost-effectiveness of using flash monitoring versus SMBG alone in patients with type 1 diabetes (T1D) receiving intensive insulin treatment in Sweden.Methods:This study used the IQVIA CORE Diabetes Model (IQVIA CDM, v9.0) to simulate the impact of flash monitoring versus SMBG over 50 years from the Swedish societal perspective. Trial data informed cohort data, intervention effects, and resource utilisation; literature and Tandvårds-Läkemedelförmånsverket (TLV) sources informed utilities and costs. Scenario analyses explored the effect of key base case assumptions.Results:In base case analysis, direct medical costs for flash monitor use were SEK1,222,333 versus SEK989,051 for SMBG use. Flash monitoring led to 0.80 additional quality-adjusted life years (QALYs; 13.26 versus 12.46 SMBG) for an incremental cost effectiveness ratio (ICER) of SEK291,130/QALY. ICERs for all scenarios remained under SEK400,000/QALY.Conclusion:Hypoglycaemia and health utility benefits due to flash glucose monitoring may translate into economic value compared to SMBG. With robust results across scenario analyses, flash monitoring may be considered cost-effective in a Swedish population of T1D intensive insulin users.

The Cost-effectiveness of a Flash Glucose Monitoring System for Management of Patients with Type 2 Diabetes Receiving Intensive Insulin Treatment in Sweden

Flash glucose monitoring, an alternative to traditional self-monitoring of blood glucose (SMBG), prevents hypoglycaemic events without impacting glycated haemoglobin (REPLACE trial). Given the potential benefits, this study assessed the cost-effectiveness of using flash monitoring versus SMBG alone in patients with type 2 diabetes (T2D) receiving intensive insulin treatment in Sweden.Methods:This study used the IQVIA CORE Diabetes Model (IQVIA CDM, v8.5) to simulate the impact of flash monitoring versus SMBG over 40 years from the Swedish societal perspective. Baseline characteristics, intervention effects, and resource utilisation were derived from REPLACE; literature and Tandvårds-Läkemedelförmånsverket (TLV) sources informed utilities and costs. Scenario analyses explored the effect of key base case assumptions.Results:In base case analysis, direct medical costs for flash monitoring use were SEK1,630,586 (€158,523) versus SEK1,459,394 (€141,902) for SMBG use. Flash monitoring led to 0.56 additional quality-adjusted life years (QALYs; 6.21 versus 5.65 SMBG) for an incremental cost-effectiveness ratio (ICER) of SEK306,082/QALY (€29,762/QALY). ICERs for all scenarios remained under SEK400,000/QALY (€38,894/QALY).Conclusions:Hypoglycaemia and health utility benefits due to flash glucose monitoring may translate into economic value compared to SMBG. With robust results across scenario analyses, flash monitoring may be considered cost-effective in a Swedish population of T2D intensive insulin users.

Early Intensive Insulin Use May Preserve β-Cell Function in Neonatal Diabetes Due to Mutations in the Proinsulin Gene

Although mutations in the proinsulin gene (INS) are the second most common cause of neonatal diabetes mellitus, the natural history of β-cell death and the most appropriate treatments remains unknown. We describe the management and outcome of two sisters with INS-mediated diabetes (S1 and S2) and suggest that more intensive insulin treatment of S2 may have resulted in better clinical outcomes. S1 was diagnosed with diabetes after presenting with serum glucose of 404 mg/dL (22.4 mmol/L) and started multiple daily insulin injections at age 4 months, followed by continuous subcutaneous insulin infusion (CSII) at age 42 months. S1 had positive genetic testing at age 4 months for the GlyB8Ser or Gly32Ser mutation in proinsulin. S2 had positive research-based genetic testing, age 1 month, before she had consistently elevated blood glucose levels. Continuous glucose monitoring revealed abnormal excursions to 200 mg/dL. Low-dose insulin therapy was initiated at age 2.5 months via CSII. At age-matched time points, S2 had higher C-peptide levels, lower hemoglobin A1c values, and lower estimated doses of insulin as compared with S1. Earlier, more intensive insulin treatment was associated with higher C-peptide levels, decreased insulin dosing, and improved glycemic control. Initiating exogenous insulin before overt hyperglycemia and maintaining intensive insulin management may reduce the demand for endogenous insulin production and may preserve β-cell function. Studies accumulating data on greater numbers of participants will be essential to determine whether these associations are consistent for all INS gene mutations.
