Negative result of an overactive immue system

The vitamin E enema works with the immune system without causing it to be overactive .Is this one reason it works?

The Cost of a Strong Immune System

by Jon Barron

Okay, so having a strong immune system is would think? The stronger the better...right? You should be buying whatever supplements you can lay your hands on to pump up your immune response...who could argue with that?

As it turns out, not necessarily. It seems that too much of a good thing, in some circumstances, may actually be bad for you. Last month, a study was published in Behavioral Ecology and Sociobiology that just might explain why the obvious ain't necessarily so.

Bird behavior
The reason for the study was an observation that when it comes to raising children, extended family units, or what is referred to as "cooperative breeding" is not that common. At first glance, shared rearing of offspring would seem to provide a host of natural advantages. It better defines the home/nest. It allows for more food to be gathered, better care to be taken of the young, not to mention, offering the potential for better education. And yet, in most species it just doesn't happen. Think lions and bears, for example. The cubs are raised by the mothers alone -- lest the fathers kill the cubs. In fact, infanticide has been found in many species, including gorillas, cats, dogs, whales, rodents, insects and fish. The bottom line is that among species, cooperative breeding is the exception, not the rule -- common primarily in humans and birds. So the question arises, with all its "apparent" advantages , why do so few species do it?

As it turns out, the benefits of cooperative breeding come with a cost. Or to put it another way, the benefits of cooperative breeding extend not only to the immediate species, but also to the pathogens and parasites that plague them. Quite simply:

Because of all the close contact among family members in cooperative breeding, there is more interaction among individuals, thus more chance for transmission of the pathogens.
Since the interaction is with close relatives, they share similar immune system capabilities -- their bodies are actually selectively breeding parasites better able to overcome those capabilities. (Any parasites that survive, by definition, survive because they can resist those capabilities.)
As Dr. Spottiswoode, the lead researcher in the study said, "This hypothesis predicts that cooperative breeders should invest relatively more in immune defense than closely related species which breed in pairs."

She tested her hypothesis by examining the PHA response of the immune system in different species of African birds. The actual methodology was to inject the birds with phytohaemagglutinin (PHA), a substance that induces an immune reaction. In particular, when PHA is inserted under the skin of a bird's wing, it causes minor swelling. Dr Spottiswoode reasoned that the amount of swelling from a dose of PHA would reveal the activity of a bird's immune system. The more at risk the bird was, the more swiftly its immune system would respond to any challenge, and the greater that response would be. That response, however, comes at a price. The stronger the response, the greater the swelling. The greater the swelling, the greater the immune stress on the bird and the more energy its immune system ended up using to fight off the effects of pathogens. The bottom line was that among 66 species tested, the PHA response was significantly higher in the 18 cooperatively breeding species. Based on Dr. Spottiswoode's hypothesis, these results suggest that cooperatively breeding birds, because of their increased exposure to more virulent pathogens, had developed "stronger" immune systems than non-cooperative breeders. But these stronger immune systems came at a cost:

Greater immune stress
More use of body resources
Increased inflammation
Although Dr Spottiswoode's research focused on birds, the principle is likely to apply to other cooperative breeders such as human beings. Indeed, the evidence is that many human infections -- malaria, measles and flu, for example -- stem from the crowded living conditions shared by modern man. As a result, we see more virulent infections, stronger immune responses, and greater stress on the body. This gives a whole new meaning to Hilary Clinton's line, "It takes a village."

Where do we see this in humans?
Back in August of 2005, I first addressed the issue of Bird Flu (although at the time, despite the beginnings of the media frenzy, I said that I didn't see it as an imminent threat -- which it turned out not to be.). More importantly, though, I proposed that contrary to most of the advice you would hear in the alternative health community, building your immune system could be a major contributing factor in mortality rates if bird flu did hit. As I said back then:

Many alternative health companies are trying to tell you to boost your immune system to protect yourself. That's a questionable tactic with bird flu -- at least if not accompanied by the use of pathogen destroyers. Death from bird flu is most likely to come from a cytokine storm triggered by your own immune system, not from the flu itself. This is the same situation we saw in the great influenza pandemic of 1918/1919.
And now, thanks to Dr. Spottiswoode's study, we have an idea as to why this happens. In the case of bird flu, the stronger immune response of "healthy" people exacts too great a cost on the human body -- literally killing it by virtue of its overreaction. Or to put it another way, the cost of an extremely strong immune response is too high.

It's interesting that almost three years later, and even with the new study now available for all to see, little has changed. Medical doctors still tell you to get flu shots to protect yourself (even though they are, at best, only marginally effective), and people in the alternative health community still tell you to build your immune system (so that your body can be overtaxed and die).

It's not just flu
Once we understand the problem -- that an overly strong immune system forced to address pathogens at full viral or bacterial load is an unbalanced immune system and will exact a cost on the body, we realize that the problem is likely to be endemic and appear in many different forms (some fatal and others not) in many different people. And it does. For example:

Endemic immune system disorders
A significant increase in diseases/symptoms such as fibromyalgia and chronic fatigue
Chronic systemic inflammation in joints, muscles, and cardiovascular systems. (Remember, just like in the birds, inflammation is an immune system response.)
Dr. Spottiswoode conducted her experiments to better understand why more animals didn't have extended families since doing so appeared to offer great benefits. In the end, she went a long way to proving her hypothesis that extended families demand much more active immune systems from individuals, which extracts a heavy cost on the body. Kudos to Dr. Spottiswoode. For me, though, I see other important information coming from this study -- information that can alter how you choose to "optimize" your immune system and prepare for any invading pathogens. What the study showed, if you look from a slightly different perspective, is that when it comes to the immune system, more is not always better. Improving the strength of the immune system comes at a cost. Optimizing the immune system, then, comes down to "cost benefit analysis."

The bottom line is yes, you want your immune system to respond strongly to any pathogens -- but not too strongly. If it responds too strongly, the costs can outweigh the benefits. An overactive immune system can lead to:

Sustained systemic inflammation
Autoimmune disorders
Overactive responses to allergens
Even death, as in the case of avian flu
So exactly what does that mean:

It means that you do want to use immune builders such as
Pau d’arco
Medicinal mushrooms
Beta glucans
Aloe vera
Bovine colostrums
But it means you also want a supply of natural antipathogens on hand to ratchet down the need for a high level immune system response.
Olive leaf extract
Oil of wild mountain oregano
Grapefruit seed extract
It's also a good idea to regularly supplement with natural immunomodulators that help to regulate immune response - moving a weak immune system up and calming an overactive immune system down. These include
When it comes to fighting disease and staying healthy, your immune system is your best friend. You want the strongest immune system response you can have without it being so strong that it overtaxes the body. If you can tone down the strength of the pathogenic attack, then a strong immune system works in your favor -- finishing off the invading little buggers as quickly as possible, but without the need to drain down your reserves. But if you don't ratchet down the strength of the attack, your immune system actually works against you -- causing chronic inflammation, immune system disorders, overactive allergy responses, or as in the case of avian flu, potentially killing you.
