Bloomberg News is not one of the news organizations we review on a regular basis.
If we did, this story – “Diabetes May Be Reversed by Long-Used Vaccine for TB” – would not get a good score.
- “A tuberculosis vaccine in use for 90 years may help reverse Type 1 diabetes and eliminate the life- long need for insulin injections“
- “Results of the trial showed that two of the three patients given BCG had signs of renewed insulin production.”
- There was no independent perspective. Other stories had no trouble finding skeptical independent experts:
- WebMD reported: “One skeptic is Steven Wittlin, MD, professor of medicine and director of the diabetes service at the University of Rochester, N.Y.
“We are always hoping for an immune cure for diabetes,” Wittlin tells WebMD. “But so far all the immune studies that looked promising in early human studies have failed in large-scale trials.”
Wittlin notes that previous efforts to treat or prevent type 1 diabetes with BCG vaccine have failed.”
- HealthDay reported: “But what happens after 20 weeks? How often would they need to give this vaccine? (asked Dr. Spyros Mezitis, an endocrinologist at Lenox Hill Hospital in New York City. )
“I’m concerned about increasing the levels of TNF in the body,” he added. “They’re saying that only the insulin-secreting cells are affected, but what are the long-term effects if it’s given repeatedly? What about the growing cells in children, because if it works it would be used in children.”
- Reuters reported: “Other diabetes researchers criticized it for going beyond the evidence in its claims about what caused the observed effects. … “There is a bit of magical thinking here,” said Dr. Domenico Accili of the Naomi Berrie Diabetes Center at Columbia University Medical Center. The idea that BCG wipes out autoimmune cells “is totally unproved.”
