AGHD individuals with nonalcoholic fatty liver disease showed specific changes in higher TAG and DAG subclass levels. Alterations in lipid profiles may contribute to metabolic dysregulation in AGHD patients. TAGs, PCs and PE fatty acids positively correlated with BMI, fasting insulin, insulin resistance index and adverse lipid parameters. In contrast, ether-linked PE-O, PC-O and LysoPE-O showed a negative correlation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study has significantly expanded the current understanding of lipid dysregulation in AGHD patients with iGCT.
