Ok! I will attempt to answer your questions...
SymiereWhat autoimmunity isThe response is a hypersensitivity reaction similar to allergies, where the immune system reacts to a substance that it normally would ignore. In allergies, the immune system reacts to an external substance that would normally be harmless. With autoimmune disorders, the immune system reacts to normal body tissues.
Mutated genes
In a normally functioning immune system, white blood cells produce antibodies to foreign invaders such as bacteria and viruses. These white blood cells also produce chemicals that aid in healing and fighting infective agents. But with psoriasis, special white blood cells called T-cells become overactive. These T-cells "attack" the skin and set off a cascade of events that make the skin cells multiply so fast they start to stack up on the surface of the skin. Normal skin cells form, mature, then are sloughed off every 30 days. But in plaque psoriasis the skin goes through this whole process in 3-6 days. Normally T-cells produce chemicals that help heal the skin. In psoriasis, T-cells produce an abnormally large amount of these chemicals and actually cause more inflammation in the skin and joints.
With regard to the genetic predisposition of autoimmunity. Autoimmunity is primarily unpredictable. If asked what the main "symptom" of autoimmunity is, the answer would be
unpredictable. It waxes and wanes
in severity, you may constantly have some manifestation of ppp,
but there are times when it will be more severe than others. ( did this not happen with you Jane, or was it not noticeable? Has your ppp never flared, and then after a few months or even weeks subsided? ) If it has, then
that is waxing and waning.
http://www.healthline.com/adamcontent/autoimmune-disordersThe outcome depends on the specific disease. Most are chronic, but many can be controlled with treatment. Symptoms of autoimmune disorders can come and go. The sudden, severe development of symptoms is called a flare up.
This quote concerning ppp. note that an abnormal reaction (
an allergy= non-self) to nicotine, may incite the genetic predisposition into action. So basically it is thought that if you have an allergy to nicotene itself, this allergy (easily detected of course) could incite the autoimmune response, as indeed many other allergies could if you carry the genetic predisposition to autoimmunity. So if you want to know if your smoking (if you do) could set this off in
you, then have a patch test done for nicotene!
Palmo-plantar pustulosis
Palmo-plantar pustulosis (PPP) is a type of pustular psoriasis that causes pustules on the palms of the hands and soles of the feet. PPP is characterized by multiple pencil eraser-sized pustules in fleshy areas of the hands and feet, such as the base of the thumb and the sides of the heels. The pustules appear in a studded pattern throughout reddened plaques of skin, then turn brown, peel and become crusted. The course of PPP is usually cyclical, with new crops of pustules followed by periods of low activity. (That is waxing and waning a symptom of any autoimmune disease, BUT it appears that it is also a symptom of ppp itself.) Those who are at risk for PPP should seriously consider not smoking, as some studies suggest that these patients may have an abnormal response to nicotine which can trigger flares of PPP.
Note also!
People who start to smoke after developing psoriasis may delay the onset of psoriatic arthritis, according to research presented at the 2007 annual meeting of the Society for Investigational Dermatology. However, because smoking causes serious health problems, everyone should avoid tobacco use.
The goals of treatment are to reduce symptoms and control the autoimmune process while maintaining the body's ability to fight disease. Treatments vary widely and depend on the specific disease and your symptoms.There is no known prevention for most autoimmune disorders.
PPP is the manifestation of the autoimmune response, and as there is also an hereditary factor you will naturally get psoriasis or one of its phenotypes, such as ppp. I have a genetic predisposition to autoimmunity, and like
both of you can have any autoimmune disease, but I can never have ppp, because I do not have the hereditary gene.
Don't quote me, but I think researchers believe that there may be more than one gene involved with psoriasis.
Genetic Causes of Psoriasis
Researchers have found 9 gene mutations that may be involved in causing psoriasis. One of these mutations on chromosome 6, called PSORS-1, appears to be a major factor that can lead to psoriasis. Mutations on genes cause certain cells to function differently.
You can have more than one autoimmune condition manifesting entirely different in the same person,
http://www.healthline.com/adamcontent/autoimmune-disordersA person may have more than one autoimmune disorder at the same time. Examples of autoimmune (or autoimmune-related) disorders include:
Hashimoto's thyroiditis
Pernicious anemia
Addison's disease
Type I diabetes
Rheumatoid arthritis
Systemic lupus erythematosus
Dermatomyositis
Sjogren syndrome
Lupus erythematosus
Multiple sclerosis
Myasthenia gravis
Reactive arthritis
Grave's disease
Celiac disease - sprue
and that above answers your question here symiere...
But then there's this:
Psoriasis (et all) is considered an autoimmune disease.
Hypothyroidism is considered an autoimmune disease.
The reason why that is possible, is because the genetic fault is a
predisposition, and not a
specific autoimmune disease.
When the cycles of PPP are stepping on each other, that's the autoimmune in overdrive, right?
But the actual symptoms - deep, hot itch to pustules to crusty scales to bloody fissures - are P....yes?
SO! When the "actual symptoms" of P are stepping on top of each other, producing layers upon layers - that is the autoimmune?
I think we have confusion here..
Please note the bold bit in blue in the PPP quote above.
I presume you mean the multiplying of the cells as described under Mutated Genes at the beginning of my post??
P are stepping on top of each other, producing layers upon layers
that is the result of the
stimulated muted hereditary gene,-consequently resulting in- the malfunction of these cells - resulting in the manifestation of the disease psoriasis.
Waxing and waning applies to my own and everybody else with an autoimmune disease. The disease manifested is the result of the autoimmune response. The autoimmune response can manifest again differently as it has with you symiere, and alison too. It depends on which cells are involved within that response, and at what point the malfunction takes place, determining the disease manifested. However in
you there is the hereditary factor to P.
JaneWhen the cycles of PPP are stepping on each other, that's the autoimmune in overdrive, right?
That's what I assumed Symiere when my PPP was active.
As explained above , yes, the abnormal response (Which because it is abnormal, is now called an autoimmune response), causes this malfunction
of these particular cells ( because you have the hereditary factor to Psoriasis) to go into overdrive. In my own case, an antigen to a normal protein found in (everybody's) skin, is produced, (therefore to *self*) and thus an abnormal antibody is produced to that abnormal antigen, ( autoantibody being of the iga type) and again produced in excessive amounts, or as you say in overdrive. That explains the resulting manifestation of the autoimmune response, which has occurred in me.
The blistering is, over various periods of time, sometimes worse than others, although never completely gone. That is typical of
all autoimmune diseases. It appears however that ppp
itself runs in cycles in this way too, and is a symptom of this manifested disease. I hope that clarifies things?
Since the Doxy with it's anti-inflammatory properties, do you think that my immune system has been calmed down?
I don't really know Jane , but I would imagine your doctor prescribed the Doxy, because your ppp at that time showed signs of infection, resulting in more pronounced inflammation of course. That treatment was very successful for you, reducing all the inflammation, not just from the infection, but that resulting from the autoimmune response ppp. You see at such times the situation can become a circle of events. If your ppp has calmed down significantly over a period of about a year, and you have had no major flare ups, and the outbreaks you have had, have not been bad at all, then you could be slowly going into remission!
SymiereI feel that if I can get it CLEAR in my mind, I can deal with it better.
That is my sole reason for all my long posts. By doing the research I am learning too and understand far better than I did, and because of that I cope better. I hated it when doctors talked "over my head", or explained things in so simple a way that it was in fact misleading. Now I say "tell me as you would a colleague, I can understand and if not I will find out what those terminologies mean."
Same as they had to do !I'm worn out!!
