Abstract
Purpose
Sotagliflozin, a dual SGLT1/2 inhibitor, enhances glucagon like peptide-1
(GLP-1) levels and GLP-1 receptor agonists are used to manage non-alcoholic
fatty liver disease (NAFLD). Study investigates the effects of sotagliflozin
on NAFLD, alone and combined with linagliptin, comparing outcomes in
normoglycemic and hyperglycemic animal models.
Methods
Obese fatty liver disease (FLD) model was induced by high-fat diet (HFD)
feeding, while a diabetic non-alcoholic steatohepatitis (NASH) model was
developed by administering a single dose of streptozotocin to neonatal mice,
followed by HFD feeding post-weaning. At termination of the study,
parameters including biochemical markers, inflammatory cytokines, hepatic
lipid content, and histopathology were assessed.
Results
In NASH mice, sotagliflozin and linagliptin reduced hepatic triglycerides by
60% and 44%, respectively, and cholesterol by 46% and 49%. Their combination
further decreased triglycerides by 68.5% and cholesterol by 83.9%. In FLD
mice, sotagliflozin and linagliptin reduced triglycerides by 33% and 17%,
respectively, and cholesterol by 46% and 21%. Combination treatment offered
no benefit, reducing triglycerides by 38% and cholesterol by 27%. Both the
treatments improved plasma fibroblast growth factor 21, hepatic
interlukin-6, glucose tolerance, steatosis and mitigated fat pad weight, but
their combination did not show additional benefit. However, combination
treatment demonstrated added benefit in modulating NAFLD activity score,
liver enzymes, glycogenated hepatic nuclei, plasma glucose and active GLP-1
levels.
Conclusion
Study underscores sotagliflozinʼs potential to mitigate NAFLD and highlights
the benefit of combining it with linagliptin in hyperglycemic NASH model,
which showed limited efficacy in normoglycemic FLD mice.
