Transcriptional analysis of bulk monocytes isolated from patients post-bariatric surgery undergoing a standardized liquid mixed-meal test intended to provoque postprandial hypoglycemia, upon treatment with either placebo, anakinra or empagliflozin

ABSTRACT: Postprandial hypoglycemia is a disabling complication of bariatric surgery. So far, no therapy exists, and the underlying mechanisms remain unclear. Here, we hypothesized that glucose-induced IL-1β leads to an exaggerated insulin response in this condition. Therefore, we conducted a placebo controlled, randomized, double-blind, cross-over study with the SGLT2-inhibitor empagliflozin (Jardiance [10mg]) and the IL-1 receptor antagonist anakinra (Kineret [100mg]). Both drugs reduced postprandial insulin release and prevented hypoglycemia. Moreover, analysis of monocytes taken from this patient population ex-vivo revealed a hyper-reactive inflammatory state in these cells. Our study proposes a role for glucose-induced IL-1β in postprandial hypoglycemia after bariatric surgery and suggests that SGLT2-inhibitors and IL-1 antagonism may improve this condition.

Project description:Palmer2014 - Effect of IL-1β-Blocking therapies in T2DM - Healthy Condition This is the model with healthy state initial conditions. A few changes were made to the model equations in order to bypass the circular dependencies apparent in SBML. Coupled algebraic equations for the species Glucose, Insulin and Proinsulin were changed to reactions which represent the ordinary differential equations found in a previously published model by De Gaetano et al (2008), [MODEL1112110003]. This reference was used by the present authors for the algebraic equations. The original Mathematica code, obtained from the supplementary material of the article can be downloaded from the link below: [Palmer2014_notebook.nb].

Palmér R, Nyman E, Penney M, Marley A, Cedersund G, Agoram B. CPT Pharmacometrics Syst Pharmacol. 2014 Jun 11;3:e118. Abstract: Recent clinical studies suggest sustained treatment effects of interleukin-1β (IL-1β)-blocking therapies in type 2 diabetes mellitus. The underlying mechanisms of these effects, however, remain underexplored. Using a quantitative systems pharmacology modeling approach, we combined ex vivo data of IL-1β effects on β-cell function and turnover with a disease progression model of the long-term interactions between insulin, glucose, and β-cell mass in type 2 diabetes mellitus. We then simulated treatment effects of the IL-1 receptor antagonist anakinra. The result was a substantial and partly sustained symptomatic improvement in β-cell function, and hence also in HbA1C, fasting plasma glucose, and proinsulin-insulin ratio, and a small increase in β-cell mass. We propose that improved β-cell function, rather than mass, is likely to explain the main IL-1β-blocking effects seen in current clinical data, but that improved β-cell mass might result in disease-modifying effects not clearly distinguishable until >1 year after treatment.
