Association between clinical and laboratory factors and response to sodium-glucose cotransporter 2 inhibitors in patients with type 2 diabetes: a retrospective observational study

Abstract

ABSTRACT Background This study aimed to investigate the association between clinical and laboratory parameters and response to therapy with sodium-glucose cotransporter 2 inhibitors (SGLT2i) in patients with type 2 diabetes mellitus (T2D). Research design and methods We retrospectively analyzed the medical records of people with T2D in whom SGLT2i was started. Clinical and laboratory parameters were recorded before, 3 and 6 months after starting treatment. Specific criteria were applied to classify participants into good and poor responders in terms of weight loss (primary outcome) and glycemic control (secondary outcome), separately. Results Fifty individuals (64% men) with a mean age of 65.8 ± 8.5 years were included in the analysis. 86% and 64% of the participants were classified into good response categories for glycemic control and weight loss, respectively. Good responders in terms of glycemic control had lower high-density lipoprotein cholesterol levels at baseline compared to poor responders (43.3 vs 57.4 mg/dl, p = 0.044). In the logistic regression analysis, a higher baseline weight was associated with a better response to therapy in terms of weight loss (p = 0.04). Conclusions Our findings suggest that specific clinical and laboratory parameters are associated with response to SGLT2i treatment and can contribute to a more personalized approach to T2D care.
