Beyond Viral Suppression: How the Right HIV Drug Helps the Gut Heal Itself
Can specific HIV drugs heal the gut? For late-stage patients, viral suppression isn't enough to stop chronic inflammation. Our 2-year trial reveals that dolutegravir, unlike darunavir, profoundly restores the gut microbiome, offering a new pathway to long-term health and reduced inflammation.

Dolutegravir restores gut microbiota in late-stage HIV-1 unlike darunavir: an open-label, randomized clinical trial - Nature Communications
Advanced HIV-1 infection is associated with gut dysbiosis, and it’s not known whether this is reversed with antiviral therapy. The ADVANZ-4 MISTRAL trial shows that dolutegravir restores gut microbiota in late-stage HIV1 patients better than darunavir, and that recovery is linked to improved immune reconstitution.

The White House has turned COVID.gov from a public health resource into a politically charged platform promoting the lab-leak theory and attacking specific scientists and the pandemic response in general. Let’s fact check its 5 headline claims… 🧵
The virus possesses a biological characteristic that is not found in nature.
2.

Data shows that all COVID-19 cases stem from a single introduction into humans. This runs contrary to previous pandemics where there were multiple spillover events.
3.

Wuhan is home to China’s foremost SARS research lab, which has a history of conducting gain-of-function research (gene altering and organism supercharging) at inadequate biosafety levels.
4.

Wuhan Institute of Virology (WIV) researchers were sick with COVID-like symptoms in the fall of 2019, months before COVID-19 was discovered at the wet market.
5.

By nearly all measures of science, if there was evidence of a natural origin it would have already surfaced. But it hasn’t.
