RESUMO
Background: 3ß-hydroxy-Δ5-C27-steroid-oxidoreductase (3ß-HSD) deficiency is a bile acid synthesis disorder that leads to the absence of normal primary bile acids and the accumulation of abnormal bile acids. This results in cholestatic jaundice, fat-soluble vitamin deficiency, acholic or fatty stools and failure to thrive. Bile acid supplementation is used to treat 3ß-HSD-deficiency and its symptoms. Methods: This report details the case of a 28-year-old woman diagnosed with 3ß-HSD-deficiency, who was treated with glycine-conjugated deoxycholic acid (gDCA). Results: gDCA treatment successfully restored normal bile acid levels, improved body weight by reducing fat malabsorption, and was well-tolerated with no observed liver problems or side effects. Conclusions: As a potent FXR ligand, gDCA might exert its action through FXR activation leading to bile acid synthesis regulation.
