Chinese Herbal Remedy May Make TB Easier To Treat
| Hello Jeff - You KNOW, WITHOUT A DOUBT, that Big Pharma will make sure
this information is buried deep and never gets to the mainstream.
Big Pharma makes a lot of money on conventional TB and Cancer treatments.
The cancer industry (and TB) Is BIG business .
Rense and Doyle will make sure people do hear about this.
Herbal Medicine May Make Tuberculosis Easier To Treat
Posted by Sarina Gleason - Michigan State
A centuries-old herbal medicine, discovered by Chinese scientists and used to effectively treat malaria, may help treat tuberculosis and slow the evolution of drug resistance.
A new study shows the ancient remedy artemisinin stopped the ability of TB-causing bacteria, known as Mycobacterium tuberculosis, to become dormant. This stage of the disease often makes the use of antibiotics ineffective.
The study is published in the journal Nature Chemical Biology.
“When TB bacteria are dormant, they become highly tolerant to antibiotics,” says Robert Abramovitch, a microbiologist and assistant professor in the College of Veterinary Medicine at Michigan State University. “Blocking dormancy makes the TB bacteria more sensitive to these drugs and could shorten treatment times.”
One-third of the world’s population is infected with TB and the disease killed 1.8 million people in 2015, according to the Centers for Disease Control and Prevention.
Is this drug combo the answer to resistant malaria?
Mycobacterium tuberculosis, or Mtb, needs oxygen to thrive in the body. The immune system starves this bacterium of oxygen to control the infection. Abramovitch and his team found that artemisinin attacks a molecule called heme, which is found in the Mtb oxygen sensor.
By disrupting this sensor and essentially turning it off, the artemisinin stopped the disease’s ability to sense how much oxygen it was getting.
“When the Mtb is starved of oxygen, it goes into a dormant state, which protects it from the stress of low-oxygen environments,” Abramovitch says. “If Mtb can’t sense low oxygen, then it can’t become dormant and will die.”
Can take 6 months to treat
Abramovitch indicated that dormant TB can remain inactive for decades in the body. But if the immune system weakens at some point, it can wake back up and spread. Whether it wakes up or stays ‘asleep’ though, he says TB can take up to six months to treat and is one of the main reasons the disease is so difficult to control.
“Patients often don’t stick to the treatment regimen because of the length of time it takes to cure the disease,” he says. “Incomplete therapy plays an important role in the evolution and spread of multi-drug resistant TB strains.”
The research could be key to shortening the course of therapy because it can clear out the dormant, hard-to-kill bacteria, he adds. This could lead to improving patient outcomes and slowing the evolution of drug-resistant TB.
Tool determines in 1 day if TB treatment is working
After screening 540,000 different compounds, Abramovitch also found five other possible chemical inhibitors that target the Mtb oxygen sensor in various ways and could be effective in treatment as well.
“Two billion people worldwide are infected with Mtb,” Abramovitch says. “TB is a global problem that requires new tools to slow its spread and overcome drug resistance. This new method of targeting dormant bacteria is exciting because it shows us a new way to kill it. ”
The National Institutes of Health, MSU AgBioResearch, and the Bill and Melinda Gates Foundation funded the research. Other researchers from Michigan State, Sweet Briar College, and the University of Michigan collaborated on the study.
