Sirtuin 3 Mediated by Spinal cMyc-Enhancer of Zeste Homology 2 Pathway Plays an Important Role in Human Immunodeficiency Virus-Related Neuropathic Pain Model.
Clinical data demonstrate that chronic use of opioid analgesics increases neuropathic pain in people living with human immunodeficiency virus (HIV). Therefore, it is important to elucidate the molecular mechanisms of HIV-related chronic pain. In this study, we investigated the role of the transcription factor cMyc, epigenetic writer enhancer of zeste homology 2 (EZH2), and sirtuin 3 (Sirt3) pathway in HIV glycoprotein gp120 with morphine (gp120M)-induced neuropathic pain in rats. ⋯ These results demonstrated that spinal Sirt3 decrease in gp120M-induced neuropathic pain was mediated by cMyc-EZH2/H3K27me3 activity in an epigenetic manner. This study provided new insight into the mechanisms of neuropathic pain in HIV patients with chronic opioids.

The management of cancer-related pain in patients with opioid use disorder (OUD) remains complex and often challenging for clinicians and patients. There is currently a paucity of data to guide best practices, and the evidence that exists is variably applied. In this hospital-based questionnaire, we sought to understand the variation in practice patterns among clinicians in palliative medicine, addiction medicine, and hospital medicine, in caring for this complex patient population. ⋯ There was also a significant difference in postdischarge subspecialty follow-up. Furthermore, the findings suggest that buprenorphine and methadone may be underutilized in this population. Patients and clinicians may benefit from additional support and standardization of practices to best manage coexisting cancer-related pain and OUD.
