I've just been reading the news reports about the swine flu outbreak.

I was wondering what anti-viral supplements would be recommended to help your body defend against influneza in general.
Thanks,

The illness acts quickly and has led to death in Mexico within five days, she said, adding among those who died were healthy young people between the ages of 20 to 44.
It is believed that cytokine storms were responsible for many of the deaths during the 1918 influenza pandemic, which killed a disproportionate number of young adults.[1] In this case, a healthy immune system may have been a liability rather than an asset. Preliminary research results from Hong Kong also indicated this as the probable reason for many deaths during the SARS epidemic in 2003.[citation needed] Human deaths from the bird flu H5N1 usually involve cytokine storms as well.[citation needed]

The excessive release of cytokines by the immune system contributes importantly to the pathogenesis of inflammatory diseases. Recent advances in understanding the biology of cytokine toxicity led to the discovery of the "cholinergic anti-inflammatory pathway," defined as neural signals transmitted via the vagus nerve that inhibit cytokine release through a mechanism that requires the alpha7 subunit-containing nicotinic acetylcholine receptor (alpha7nAChR). Vagus nerve regulation of peripheral functions is controlled by brain nuclei and neural networks, but despite considerable importance, little is known about the molecular basis for central regulation of the vagus nerve-based cholinergic anti-inflammatory pathway. Here we report that brain acetylcholinesterase activity controls systemic and organ specific TNF production during endotoxemia. Peripheral administration of the acetylcholinesterase inhibitor galantamine significantly reduced serum TNF levels through vagus nerve signaling, and protected against lethality during murine endotoxemia. Administration of a centrally-acting muscarinic receptor antagonist abolished the suppression of TNF by galantamine, indicating that suppressing acetylcholinesterase activity, coupled with central muscarinic receptors, controls peripheral cytokine responses. Administration of galantamine to alpha7nAChR knockout mice failed to suppress TNF levels, indicating that the alpha7nAChR-mediated cholinergic anti-inflammatory pathway is required for the anti-inflammatory effect of galantamine. These findings show that inhibition of brain acetylcholinesterase suppresses systemic inflammation through a central muscarinic receptor-mediated and vagal- and alpha7nAChR-dependent mechanism. Our data also indicate that a clinically used centrally-acting acetylcholinesterase inhibitor can be utilized to suppress abnormal inflammation to therapeutic advantage.

More than not-supplementing if done correctly and if those supps work to begin with, but improved survival is good enough..Really though, how much can supplementation help against a potential pandemic?
I'm assuming it could be the other way round if it kills you via a cytokine storm. Then again, some of those supps do not necessarily work via increased immune responses.I mean a healthy immune system is great,
So what? There is no "true immunity " to the flu anyway, not even using those meds:but without true immunity you would be bound to catch it eventually.
amantadine and rimantadine, but susceptible to oseltamivir (Tamiflu) and zanamivir (Relenza).

"—Genetic analysis of virus samples in the two countries is continuing. The CDC says tests results show the U.S. and Mexican viruses are essentially the same, but some experts have not ruled out the possibility that the virus is changing as it leaks across the border to the north.
—Perhaps nutrition levels are worse in some Mexican communities — poor nutrition can degrade a person's immune defenses, and make them more susceptible to illness.
—Air quality in Mexico City is considered terrible. That too may have affect patients confronted with a novel respiratory disease.
—Access to medical care has been an issue in Asia, where a rare bird flu — which does not spread easily from person-to-person — has killed more than 200 over the last several years. Maybe Mexican patients have also had trouble getting medical care or antiviral drugs, some have speculated — even though the government provides health care.
All that is speculation at this point.
"The question of why the virus appears to be more virulent in Mexico is one that we are looking intensively into," the CDC's Schuchat said. "Rather than speculate, it's important for the science to lead us on this.""

They have discovered anti-bodies that neutralise multiple strains of the influenza virus, and a so-called "pan-therapy" or broad-spectrum vaccine could be just five years away.
The findings have been published in Nature Magazine.
Dr Robert Liddington from the Burnham Institute in California says researchers gave mice lethal doses of the H5N1 bird flu, then injected them with the antibodies.
"We were surprised and actually delighted to find that these antibodies also neutralised a majority of other influenza viruses including most of the regular seasonal flus," Dr Liddington said.

I'm not a virologist, so knowledge is very limited, rendering a lot of my comments rather worthless.
So we are looking at treatments that apply to a cytokine storm?
According to Wikipedia those include:
-OX40 IG
-ACE inhibitors and Angiotensin II Receptor Blockers
-Corticosteroids
-Free radical scavengers
-TNF-alpha blockers
I need to look more into this, as I am unfamiliar.
Posted 26 April 2009 - 04:00 AM
Because the US victims were kids? As Maxwatt mentions above, this virus, like the 1918 pandemic flu, hits young adults hardest.Any ideas why the same flu is having a different mortality rate so far between mexico and the U.S

At the risk of revealing and being embarrassed by my anti-establishment vigor of a few years ago:
SARS anyone?
Bird Flu anyone?
West Nile Virus anyone?
It was said that if SARS ever left the far east (or wherever it was first reported) that it would make the 1918 pandemic look like child's play. It did spread, but here we are 6 years later. Many of you probably also remember the immense hysteria that developed in the U.S. over the substantially non-lethal West Nile Virus.
I realize the danger in the "super bug" scenario, but I have also been alive long enough to have seen innumerable waves of media-generated "super bug" hysteria. Is the swine flu the one? I don't know. But what I do know is that open discussions on how best to combat new viruses, like this one here, are better than cowering in fear and quarantining every city in the world. The more we learn about the immune system and how we live in balance with the viral and bacterial ecosystems - most of the time - the sooner we will be able to develop newer more effective strategies for keeping people alive.

Offhand, I'd guess that you would want about a thousand times the dose of steroid. Nasal inhalers are typically micrograms of steroids, while a systemic dose that could really knock down major inflammation would be milligrams of a prednisone-class steroid. I didn't look up the contents of Nasonex, but that's my guess.I'm currently using a corticosteroid (Nasonex) a was given a puppy 2 weeks ago, but sadly it appears I'm allergic to it so my doctor prescribed it. Anyway, does this mean I'm less likely to have a cytokine storm?

Well, 70+ people in Mexico are dead and everyday you have new infections, so I wouldn't consider quarantine a sign of being a coward they're taking precautions to stop the disease from spreading.

Seems this strain has already spread to a few countries and passed through multiple airports.
Someone else asked why is it non-lethal in the U.S.? Two people in Kansas had it and both are now fine. Remaining alert and on the watch is fine. I expect the media will make it out worse than it will really end up. Remember that approximately 40,000 people in the U.S. and 500,000 worldwide, die every year from regular human strains of flu.

The Kansas couple were older, not in the vulnerable age-range. However, viruses that have jumped to a new host are extremely mutable and still rapidly mutating. They are adapting to a new host, and are in the process of striking a balance between virulence and contagion. Killing the host too quickly is a poor strategy for a virus, it will not spread and will go extinct. It is possible the virus has already adapted to its human host and now less lethal. This was the pattern seen with SARS in china. The pathogen adapts to its host, and becomes less lethal which is the usual case. In nature, sometimes a pathogen finds a way to spread by a long contagious dormancy or by being extremely contagious. With current public health practices of detection and containment, extreme virulence leads to rapid quarantine and extinction of lethal strains.
I speculate that rapid communication and quarantine methods are having an effect, and causing the virus to develop less virulence in order to survive; the milder strains out-compete the fatal ones. If we had had the WHO, the current degree of communication and the rapid containment response we are seeing now, the "Spanish Flu" of 1918 might have faded rapidly rather than becoming a pandemic.

Now they're reporting suspected cases in France, New Zealand, Spain; all are from people who traveled to Mexico.
