Spoonful of Sugar Helps the Persistent Bacteria Go Down
Doctors have discovered that adding sugar to antibiotics increases their ability to knock out persistent staph infections (abstract). Certain types of bacteria called persisters shut down their metabolic processes when exposed to antibiotics. Adding sugar keeps the bacteria feeding, making them more susceptible to drugs. From the article: "Adding such a simple and widely available compound to existing antibiotics enhances their effectiveness against persisters, and fast. One test showed that a sugared up antibiotic could eliminate 99.9 percent of persisters in two hours, while a regular antibiotic did nothing. Doctors believe that this discovery will help treat urinary tract infections, staph infections, and strep throat, but its most life-saving application may be against the age-old disease tuberculosis. This infection of the lungs kills many people, and is hard to fight off. A little sugar could help save a lot of lives."
I'm taking this with a grain of salt.
Don't hunters already use this method, somehow? Bait an animal with food to lure it out in the open and then kill it?
Maybe some sugar in my coffee will help get rid of the bone infection in my jaw after the dentist screwed up my root canal. They got me on 2 types of antibiotics the infections hurts my face up to my eye. Funny thing is I try and avoid sugar even though I really like sweet coffee. Doubt it is that simple though.

A spoon ful of sugar helps the medicine go down or in this case more effective.

Discovered? No, we've known this and used this for years. It's a typical procedure to treat difficult wounds that are failing to close by 2nd or 3rd intention with sugar or honey. We also grind up fenitoin pills (used to treat epileptics) and add them to the wound, since fenitoin stimulates fibroblasts and helps with would healing. Of course this is not an FDA approved use of the drug, but it works.

...the reason why we currently think honey works is not because of sugar, but because of enzymes in it which produce hydrogen peroxide.
Xylitol is another form of sugar that in addition to low calories and insulin response, kills bacteria and the evil Helicobacter pylori that causes cavities and ulcers. Stay tuned for the 2027 study that will prove it effective!
...omphaloskepsis often...
How exactly can this technique be used to fight tuberculosis, which lives in the lungs? The sugar in the antibiotic would be absorbed into the blood stream before the antibiotic could get to the infection. Unless they're talking about inhaling the antibiotic with the sugar.. which I suppose is a possibility.
Maybe it's some kind of bonding process that bonds the sugar to the antibiotic? I suppose I could read the article if I was that curious.

It's not candy, it's medicine dammit.
"I assumed blithely that there were no elves out there in the darkness"
Perhaps there is more to the placebo effect than we realize! lol
when they get the patent.
I love Jesus, except for his foreign policy.
Most antibiotics are to be taken just after a meal , when your blood sugar levels are peaking.
However , maybe a little more sugar wouldn't be a bad idea.
I can see it now. Drug companies will take their existing antibiotics, add a bit of sugar, and then upcharge $5 per fill for Sugarfukitol over normal Fukitol.
If these bacteria feed on sugar, then wouldn't significantly cutting down on sugar when treating them make good sense?
I know I've never had a doctor make such a recommendation before though.
until we run out of gasoline, then the price of sugar might go to $1000/pound, but by then we'd all have probably switched to biogas and biodiesel
No I won't!
Religion is what happens when nature strikes and groupthink goes wrong.
I'm expecting a "new formula" for damn near every drug that could benefit from this...of course big pharma is going to claim they added "medical-grade" sugar, to justify the 200% price increase.
What does this mean for previous studies that use a sugar pill for placebo?
If the placebo itself was causing a positive reaction instead of being neutral, how much material needs to be reviewed again?
Patent sugar, sue the sugar manufacturers for infringement, destroy the sugar industry. When sugar is only available in our pills, charge $200 for a box of them. Shut down production after 5 years, and lock up the patents for the next 200 years. Implement worldwide. Profit! Sugar is gone.
Can people please read the article before making inane comments, we are talking about aminoglycosides here not glucose, fructose or sucrose. This is a amino-modified sugar that are not absorbed in the gut. They have been around for a long time but until now they had not been used in conjunction with specific metabolites. So this has nothing to do with diabetics or blood sugar.
I've heard of putting sugar on a cut with some antibiotic ointment, supposedly to promote faster healing. I hadn't heard that it was supposed to improve the effectiveness of the antibiotic, though. I thought it was to promote cell growth.

This was an interesting article. I especially like the the fact that sugar can aid in the improvement of the antibacterial meds and rid the pesky little bacteria

So apparently a placebo (sugar pill) actually CAN have real effect!
A spoon full of sugar helps the medicine go down.
Love it... guess the old home remedy of "spoonful of sugar and lemon juice" to get rid of colds or other maladies faster wasn't ever factored into...? Big Pharma is nothing but a bunch of money-grubbing meat heads. They don't give a crap about mankind. They'd rather pump everyone full of drugs so you continue to stay sick and buy their medicines/remedies. Eat whole and natural foods and you'd be amazed at how healthy you become.
It is hardly surprising this method works. It is one man has used for several millennium or more when making beer. Once yeast is pitched it will consume all or a good portion of the existing sugars. Once the alcohol content reaches a certain level or there is no more sugars left, they will go dormant. You can reactivate them by adding more sugar; there is of course a limit to the amount of additional sugar that can be added and the yeasts alcohol tolerances; some yeast strains are more tolerant of high alcohol levels than others.

Just a spoonful of sugar makes the medicine go down!
In this case that old adage happens to apply to both the host and the invader.
Gee...I don't know WHAT to believe any more!!!

Agile Spaceport - You will never find a more wretched hive of scrum and villainy. We must be cautious.
The glucose is the metabolite and is used alongside an aminoglycoside antibiotic. It is aminoglycoside dependent because adding the sugar only works with aminoglycoside antibiotics: mannitol (the sugar) was tested with gentamicin (an aminoglycoside antibiotic), ofloxacin (a quinolone antibiotic) and ampicillin (a beta-lactam, specifically a penicillin antibiotic) and the only one which showed an improved response was the mannitol + gentamicin combination.
Glucose, mannitol and fructose then showed the greatest response with gentamicin (ribose, glycerol etc were much lower).
Have you read the article?
So - lemme get this... Mary Poppins was right? A spoonful of sugar really does help the medicine go down?
Studies have pointed to the fact that many bacteria still "eat" the Xylitol -- they just can't digest it, and starve, or are otherwise impaired. Not a bad thing in these cases.
http://www.ncbi.nlm.nih.gov/pubmed/21037297 for one of many cromulent studies out there involving bacterial uptake of Xylitol.
Bacteria both having been intelligently designed and causing disease doesn't necessarily imply a malevolent Creator. It only means that they've microevolved from the bacteria that the Creator put in mammals' intestines.
...with animals. It's called "bait".

Like anyone can even know that

Yeast is a fungus, not a bacterium. You can't assume that a technique that works for one kingdom will work for another. Furthermore, what the study essentially says is that sugar enhances the susceptibility of bacterium to antibiotic drugs. Now, it might be the case that the same thing holds for fungi and anti-fungal medication as well, but as far as I am aware, that would also be big news.
When preserving food by heating it, it makes a difference whether the bacteria are active or dormant. You kill them much more effectively, if you catch them feeding. If you do other preserving steps (like unfavorable pH or osmotic conditions) too early, bacteria go dormant and survive the heat much better.
So, now the FDA can label sugar a drug, make it available only with a prescription, and drive the cost up to $150/oz?
"but its most life-saving application may be against the age-old disease tuberculosis." What a tragedy. Tuberculosis was practically unheard of in the U.S. by the 1970s and 80s, but experienced a resurgence due to failure to care for cases occurring among AIDS patients, the homeless, the poor, and illegal immigrants. Tuberculosis was once treatable--not at great expense, but not with one cheap vaccine shot, either; careful treatment and followup was needed to make sure that the infection was completely cured. This wasn't done, and the result is that now we have resistant strains.
Infectious disease does not know how to respect social status, and the upper- and middle classes cannot be healthy if the poor are sick. As the debate over health care continues, it is something to keep in mind.
I hope this new advance works. Otherwise, boomers may be the only generation in the history of the human race to live our entire lives free of the terror of bacterial infection.
"How to Do Nothing," kids activities, back in print!
Yes, I get the joke, but the usual disclaimer for these kind of results applies: did this work in vivo or just in the test tube? The abstract shows one experiment done in vivo: they introduced infected catheters into mice, then treated the mice with 1) nothing, 2) antibiotic, and 3) antibiotic plus mannitol (a sugar alcohol). Option 3) killed substantial amounts of bad bacteria, while the others did not. So that's good. But... they used kind of a lot of mannitol - 1.5 g/kg - which would be the equivalent of a couple of ounces (twice daily) for a typical human. That might be tough to swallow (so to speak).
More buts: all of these results seemed to apply to biofilms, and although controlling the growth of biofilms is important, infecting bacteria are most likely not in the form of biofilms after they've invaded the body. And it's unclear to me whether any of the other experiments were done in vivo. Also, if the presence of sugar at the infection site is key to getting this to work, that might be problematic - mammal bodies keep blood sugar concentration on fairly tight control, no matter how many spoonfuls of sugar you eat, so it might be tough to produce the sugar concentration you need at the infection site.
Bottom line: sounds like interesting, promising research. But bear in mind that it's not ready for prime time now, and might not ever be.
Actually, several sorts of bacteria (notably including those responsible for tooth decay), are attracted to xylitol, will attempt to eat it, and and then starve.
Even if this turns out to work in real life, the amount of sugar used to accompany antibiotics would be dwarfed by, say, world-wide production of Coca-Cola alone. And of course that's only one current use of sugar. This use wouldn't amount to a drop in the bucket by comparison.
A noob reading this might think, just eat a spoonful of honey with my pills and my infection will be cured better or faster. Somehow I don't think its that simple. Reading the full article in nature costs $32 so I can't know but most probably, the experiment was done in vitro (in a petri dish, test tube or something). Eat honey with your antibiotic pills and unless you have diabetes, most probably your body will regulate your blood sugar levels so it remains constant
