May 21, 2013 — (Bronx, NY) — In a striking, unexpected discovery, researchers at Albert Einstein College of Medicine of Yeshiva University have determined that vitamin C kills drug-resistant tuberculosis (TB) bacteria in laboratory culture. The finding suggests that vitamin C added to existing TB drugs could shorten TB therapy, and it highlights a new area for drug design. The study was published today in the online journal Nature Communications.
TB is caused by infection with the bacterium M. tuberculosis. In 2011, TB sickened some 8.7 million people and took some 1.4 million lives, according to the World Health Organization. Infections that fail to respond to TB drugs are a growing problem: About 650,000 people worldwide now have multi-drug-resistant TB (MDR-TB), 9 percent of whom have extensively drug-resistant TB (XDR-TB).TB is especially acute in low and middle income countries, which account for more than 95 percent of TB-related deaths, according to the World Health Organization.
The Einstein discovery arose during research into how TB bacteria become resistant to isoniazid, a potent first-line TB drug. The lead investigator and senior author of the study was William Jacobs, Jr. Ph.D., professor of microbiology & immunology and of genetics at Einstein. Dr. Jacobs is a Howard Hughes Medical Institute investigator and a recently elected member of the National Academy of Sciences.
Dr. Jacobs and his colleagues observed that isoniazid-resistant TB bacteria were deficient in a molecule called mycothiol. “We hypothesized that TB bacteria that can’t make mycothiol might contain more cysteine, an amino acid,” said Dr. Jacobs. “So, we predicted that if we added isoniazid and cysteine to isoniazid-sensitive M. tuberculosis in culture, the bacteria would develop resistance. Instead, we ended up killing off the culture— something totally unexpected.”
The Einstein team suspected that cysteine was helping to kill TB bacteria by acting as a “reducing agent” that triggers the production of reactive oxygen species (sometimes called free radicals), which can damage DNA.
“To test this hypothesis, we repeated the experiment using isoniazid and a different reducing agent— vitamin C,” said Dr. Jacobs. “The combination of isoniazid and vitamin C sterilized the M. tuberculosis culture. We were then amazed to discover that vitamin C by itself not only sterilized the drug-susceptible TB, but also sterilized MDR-TB and XDR-TB strains.”
To justify testing vitamin C in a clinical trial, Dr. Jacobs needed to find the molecular mechanism by which vitamin C exerted its lethal effect. More research produced the answer: Vitamin C induced what is known as a Fenton reaction, causing iron to react with other molecules to create reactive oxygen species that kill the TB bacteria.
“We don’t know whether vitamin C will work in humans, but we now have a rational basis for doing a clinical trial,” said Dr. Jacobs. “It also helps that we know vitamin C is inexpensive, widely available and very safe to use. At the very least, this work shows us a new mechanism that we can exploit to attack TB.”
The paper is titled, “Mycobacterium tuberculosis is extraordinarily sensitive to killing by a vitamin C-induced Fenton reaction.” The other contributors are Catherine Vilcheze, Ph.D., Travis Hartman and Brian Weinrick, Ph.D., all at Einstein.
The study was supported by a grant (AI26170) from National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.

About Drug-Resistant TB
Multi-drug-resistant TB (MDR-TB): TB that does not respond to isoniazid and rifampicin, the two most potent anti-TB drugs. Extensively drug-resistant TB (XDR-TB): TB that is resistant to rifampicin and isoniazid, as well as to any member of the quinolone family of antibiotics and at least one of four second-line injectable anti-TB drugs.

Special edition to mark World TB day maps new issues and approaches to curbing spread of infection
During the 1930s, dedicated sanitaria and invasive surgery were commonly prescribed for those with the infection – usually caused by Mycobacterium tuberculosis, which the editors describe as “the most successful human pathogen of all time.”
TB often lies dormant with no symptoms, but in a proportion of cases, becomes active, predominantly attacking the lungs. But it can also affect the bones and nervous system, and if left untreated can be fatal.
The infection is developing increasing resistance around the world to the powerful drugs currently used to treat it.
“Whatever we may have once optimistically thought, TB remains with death, taxes and political chicanery as being inevitable, unavoidable and deeply unpleasant,” write the joint editors, Andy Bush and Ian Pavord.
“It shows every sign of weathering the storm and superb randomised controlled trials, to emerge in ever-increasingly drug-resistant forms, potentially turning the clock back to the 1930s,” they say.
“This edition of Thorax, coinciding with world TB day, is themed to recognise the ongoing sinister successes of Mycobacterium tuberculosis, unarguably the most successful human pathogen of all time,” they conclude.
The issue contains international research papers, looking at a broad range of issues, from the risk of TB after seroconversion to HIV infection, to the impact of ethnicity on the pattern of disease.
Could cod liver oil help combat tuberculosis?
Repost from Dec 2011
A review of a historical study from 1848 reveals that cod liver oil was an effective treatment for tuberculosis, says Professor Sir Malcolm Green in the Christmas issue published on bmj.com today.
In the study, carried out by physicians at the Hospital for Consumption, Chelsea (now the Royal Brompton Hospital), 542 patients with consumption (tuberculosis) received standard treatment with cod liver oil. These patients were compared with 535 ‘control’ patients who received standard treatment alone (without cod liver oil).
While improvement rates were similar in the two groups, the disease was stabilised in 18% of the patients given cod liver oil, compared with only 6% of those in the control group. Deterioration or death occurred in 33% of patients given standard treatment alone, but in only 19% of those given cod liver oil, a reduction of 14%.
Professor Green says that some children are still given cod liver oil today and perhaps this relates back to the late 19th and early 20th centuries when cod liver oil was widely used to treat and prevent tuberculosis.
He adds that the steady fall in tuberculosis deaths in the late 19th and early 20th centuries is often attributed to better living conditions. While a reduction in overcrowded living might have reduced transmission, Green believes improved nutrition was probably as important. “It could well be that the widespread use of cod liver oil encouraged by doctors played a significant part,” he writes.
Cod liver oil is a rich source of Vitamin D, which we now know is important in fighting infections, as well as preventing conditions such as rickets, says the author.
He says: “A role for vitamin D in combating tuberculosis gives a rational basis for sunshine therapy, which was widely practised for patients in sanatoriums before chemotherapy became available, as vitamin D is synthesised in the skin when exposed to the sun. Patients were put out on their beds to lie in the sun in summer and winter, and many were sent to Switzerland and other sunny countries for treatment.” He adds that today many patients who develop TB in the UK are found to be Vitamin D deficient.
Green concludes that since tuberculosis is still a common infection, accounting for millions of deaths annually across the world, there may yet be a role for vitamin D supplements in combating this terrible killer.
