详细描述
Synopsis Full study title: Assessing the impact of integrase strand transfer inhibitors (INSTI) to protease inhibitor (PI) switch on insulin sensitivity and fat metabolism (ADIPOSITY): a sub-study of DEFINE
Endpoints and objectives:
The following endpoints will be determined 12 and 24 weeks after switch from an INSTI-based antiretroviral therapy (ART) regimen to a PI-based regimen:
Primary endpoint: Change in insulin sensitivity (SI) at 12 weeks assessed by using a 3-hour frequently sampled oral glucose tolerance testing (fsOGTT).
Secondary endpoints: 1) Change in insulin sensitivity (SI) at 24 weeks assessed by using a 3-hour frequently sampled oral glucose tolerance testing (fsOGTT); 2) Change in insulin secretion during the fsOGTT assessed by using C-peptide deconvolution; 3) Change in intrahepatic triglyceride (IHTG) content measured by magnetic resonance imaging (MRI); 4) Change in adipocyte size by the osmium tetroxide fixation technique; and 5) Change in expression of genes associated with adipose tissue development, lipogenesis, inflammation and endocrine function by RNA sequencing.
