Abstract

Aims Rural, agro-pastoralist Maasai in East Africa exhibit low prevalence of diabetes, yet little is known about their physi-ological response to glucose loads and whether sex has an impact on glucose metabolism, including incretin hormones.

Methods We included 58 (29 men, 29 women) adult Maasai without diabetes living in rural Tanzania. Clinical background characteristics were measured, and they were exposed to an oral glucose tolerance test (OGTT) after an overnight fast. Plasma glucose, insulin/C-peptide, glucagon, glucose-dependent insulinotropic polypeptide (GIP), and glucagon-like pep-tide-1 (GLP-1) were analysed.

Results Mean age was 34.8 (range 17–65) years, and mean body mass index (BMI) was 20.3 (range 14.0-30.9) kg/m2 with two individuals being overweight and 14 being underweight. Men had a higher mean fasting glucose concentration (5.2 vs. 4.9 mmol/L, p=0.031), while women exhibited a higher OGTT-derived mean GLP-1 concentration at 2-h (8.5 vs. 5.1 pmol/L, p=0.005). Total area-under-the-curve (tAUC) for GLP-1 was higher in women compared to men (1336 vs. 870 pmol x min, p=0.011). Sex- and BMI-adjusted regression analyses for tAUC showed higher values of insulin, C-peptide and GLP-1 in women (p<0.10).

Conclusions Sex differences were found in fasting glucose and OGTT-derived insulin/C-peptide and GLP-1 concentrations. Research using more sophisticated methodology is needed to further explain the glucose metabolism phenotype in Maasai

Abstract

Background Immune checkpoint inhibitor (ICI)-induced diabetes is a rare endocrine immune-related adverse event, and long-term pancreatic magnetic resonance imaging (MRI) findings after disease onset have not been well characterized.

Case presentation An individual developed abrupt hyperglycemia during pembrolizumab therapy for recurrent renal cell carcinoma and subsequently required insulin therapy. Serum C-peptide rapidly declined to below the detection threshold, whereas pancreatic enzyme levels remained within normal limits throughout follow-up. MRI performed 1 day after diagno-sis demonstrated diffuse high signal intensity on diffusion-weighted imaging (DWI) and reduced apparent diffusion coeffi-cient (ADC) values throughout the pancreas. Serial imaging over 25 months showed progressive pancreatic atrophy, whereas the DWI/ADC features persisted.

Conclusion This case provides a new descriptive longitudinal radiological observation of persistent diffusion-related pancre-atic MRI findings and progressive pancreatic atrophy after the onset of ICI-induced diabetes.

Abstract

Background and aims Although continuous glucose monitoring (CGM) devices are now standard of care among Type 1 diabetes patients, they are still relatively underutilized in Type 2 diabetes (T2D), particularly in those patients not treated with insulin. Widespread adoption continues to be hindered by a combination of factors. Chief among these is the scarcity of long-term, large-scale clinical trials demonstrating the benefits of the use of CGM in T2D. This meta-analysis aimed to address this gap by comparing CGM with self-blood glucose monitoring (SBMG), with primary outcomes of HbA1c and time in range (TIR) in insulin-treated and non-insulin-treated TD2 patients.

Methods and results Following the stringent rules mandated by our National Health Service (which requires a panel com-posed of all stakeholders involved in diabetes treatment, and includes PICO, GRADE, AGREE, and meta-analyses), we performed a systematic review of RCTs that enrolled two groups of individuals with T2D, those treated with insulin (includ-ing basal and basal-bolus regimens), and those receiving treatments other than insulin. All included trials compared CGM with structured blood glucose monitoring (SBGM) with glycated hemoglobin (HbA1c) as the main endpoint. Based on the strength and consistency of the evidence, the panel issued a strong recommendation in favor of CGM for individuals with T2D treated with insulin (including those on basal insulin alone) and for individuals with T2D not treated with insulin, par-ticularly for those with glycated hemoglobin levels≥7%. From a pharmacoeconomic perspective, outcomes were positive in both patient groups.

Conclusion CGM represents a clinically effective and cost-efficient approach to optimizing glycemic control in T2D, becom-ing mandatory among individuals on insulin therapy. Our findings support a shift in clinical practice toward the more widespread use of CGM in T2D, with regulatory frameworks and reimbursement policies needing to adapt accordingly.
