GSE132781: 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

Bulk RNA sequencing

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-1 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-1 in postprandial hypoglycemia after bariatric surgery and suggests that SGLT2-inhibitors and IL-1 antagonism may improve this condition.
