A second child dies in a Chinese gene-editing trial

Last month, Science reported that a 6-year-old girl died while participating in a gene-editing clinical trial based in China. Researchers did not disclose the death, instead publishing an article on the therapy’s results in mice. Now, a separate Chinese institution has — belatedly, some argue — acknowledged the death of another child related to gene-editing research. After more than a year of silence on a Duchenne muscular dystrophy study and a monthslong STAT investigation, the company, HuidaGene, disclosed that the trial was shut down when a young boy died after receiving the therapy.
The disclosure raises concerns about the quality and transparency of China’s more lightly regulated pathway for drug trials — a form that has been gaining support in the U.S. The “thing that bothers me is the lack of transparency,” said Kiran Musunuru, a gene-editing researcher at the University of Pennsylvania. “There could be many of these events and we have no idea.” Read more from STAT’s Jason Mast and contributor Brian Yang on what this all means.

Poop pills for peanut allergies?
Peanut allergies among children have plummeted in recent years. But many people still live with the clinical aversion, which can be dreadful, and at times deadly. A new, small clinical trial offers hope: a fecal microbiome transplant, delivered via “stool capsules.”
Among 15 participants with the allergy, six showed increased peanut tolerance one month post-transplant, with a few lasting as long as four months. Read more from STAT’s Lauren Chan on what questions remain and where researchers want to go next.

Covid can reactivate dormant viruses, per study
Early research has shown that a Covid-19 infection can reactivate common, chronic viruses like Epstein-Barr and cytomegalovirus. A study published yesterday in Nature found that, among patients hospitalized with Covid, the reactivation of certain dormant viruses is correlated with the severity of a person’s disease. Additionally, there are temporal patterns to when certain viruses reactivate during sickness.
In a study including longitudinal data from more than 1,100 hospitalized Covid patients, researchers found significant reactivation of two virus families during acute infections: Herpesviridae and Anelloviridae. Reactivation of Anelloviridae in particular was strongly associated with long-term physical disability and long Covid. These reactivations also occurred frequently in “immunocompetent” people, challenging the presumption that this sort of reactivation is concentrated in immunocompromised people, the authors wrote.
