Anti-Human GLP-1(aa 7-36) monoclonal antibody

We retrospectively assessed gluco-regulatory hormones over 10 h (including two meals) of fully automated closed-loop insulin delivery using faster (FA) versus standard insulin aspart (IAsp) in adults with type 2 diabetes [n = 15, age 59 +/- 10 years, body mass index 34.5 +/- 9.1 kg/m(2), glycated haemoglobin 7.7 +/- 1.2% (60 +/- 13 mmol/mol)]. Plasma concentration of human insulin, IAsp, C-peptide, glucagon, glucagon-like peptide 1, glucose-dependent insulinotropic peptide and peptide tyrosine tyrosine were measured every 15-30 min. Endogenous insulin secretion was calculated using C-peptide deconvolution and exposures to hormones were compared using their mean plasma concentrations. Ten-hour exposure of IAsp was higher with FA versus IAsp (P= .037) in line with the 10% higher insulin requirements to achieve similar glucose control. No significant difference was found for total insulin exposure and endogenous insulin secretion. Similarly, other gluco-regulatory hormones did not significantly differ. In conclusion, the faster pharmacokinetic profile and slightly higher aspart exposure of FA versus IAsp remained without significant effects on endogenous insulin secretion or other gluco-regulatory hormones. Further studies are warranted to explore the metabolic and endocrine effects of novel insulins with accelerated pharmacokinetic properties.

Background While obesity and overweight status are firmly established risk factors for Type 2 diabetes mellitus (T2DM), a substantial proportion of diabetic individuals, especially in Africa and Asia, are often underweight or normal weight. However, very little is known about the immunological and metabolic profiles of these individuals. Methods This study aimed to assess the relationship between malnutrition and Type 2 diabetes mellitus (T2DM). We examined a variety of analytes associated with the immunological and metabolic profiles of T2DM individuals with low (< 18.5 kg/m2) or normal (18.5-24.9 kg/m2) body mass index (BMI). To this end, we measured plasma levels of HbA1c, glucose, insulin, glucagon, adipocytokines and Type 1, Type 2, Type 17, pro-inflammatory and regulatory cytokines in T2DM individuals with low BMI (LBMI) or normal BMI (NBMI) with small sample size n = 44 in each group. Results LBMI individuals exhibited significantly higher levels of HbA1c, random blood glucose, insulin and glucagon compared to NBMI individuals. Similarly, LBMI individuals exhibited significantly higher levels of adiponectin and adipsin and significantly lower levels of leptin in comparison to NBMI individuals. LBMI individuals also exhibited significantly lower levels of the Type 1, Type 2, Type 17, pro-inflammatory and regulatory cytokines in comparison to NBMI individuals. Finally, while the metabolic parameters exhibited a significant negative correlation with BMI, the immunological parameters exhibited a significant positive correlation with BMI. Conclusions Malnutrition is associated with a significant modulation of glycemic, hormonal and cytokine parameters in T2DM. Hence, the biochemical and immunological profiles of T2DM is significantly influenced by BMI.
