Key Points: The rate of prescription of opioid medication decreased between 2011 and 2020 for patients with ESRD. The risk of death for dialysis and kidney transplant patients increased as morphine milligram equivalents in prescriptions increased.
Background: Pain is important for patients with kidney failure, but opioid medication prescriptions are associated with morbidity and mortality.
Liver x receptor alpha (LXRα, Nr1h3) functions as an important intracellular cholesterol sensor that regulates fat and cholesterol metabolism at the transcriptional level in response to the direct binding of cholesterol derivatives. We have generated mice with a mutation in LXRα that reduces activity in response to endogenous cholesterol derived LXR ligands while still allowing transcriptional activation by synthetic agonists. The mutant LXRα functions as a dominant negative that shuts down cholesterol sensing.
