Millions of people
suffer from the skin condition eczema worldwide. More than 15 million
people in the United States alone have this condition. If you are
one of them, you most likely have red, raised, itchy patches that
sometime become infected or become "weepy". Eczema tends
to occur on the face, neck, upper back or chest, wrists, hands, in
the folds behind the knee and elbows.
Lets look at the causes,
triggers and treatments of this inflammatory skin condition. It may
also be called atopic eczema.This skin disorder
is generally attributed to a malfunction in the body's immune system.
You may have an increased level of IgE antibodies in your blood. Eczema
tends to occur in people who have a family history of allergies.
Many children who get this disease outgrow it at puberty, but later
develop "dermatitis" or eczema as adults. Risk factors
may include exposure to tobacco smoke, skin infections, changes in
climate, irritating chemicals, and food allergies.
Eczema is a hypersensitivity
reaction. Here's kind of how it works: your body is "more reactive",
or more sensitive to things, and so anything that touches your skin,
affects it from inside or from outside, will make you itch. That itch
will make you scratch, you may even be unaware that you are scratching
it. The scratch will bring out the eczema, and then you have a problem.
There
are different sizes of patches that can be red. There can be some
scaly patches. The are most often very itchy and uncomfortable. Some
people have little bumps that stick up and some have bumps with fluid
in it. And those who do a lot of scratching, the skin markings are
thicker and you can see the skin much easier than people who've had
it on an acute basis. Identifying eczema may be tricky. (I know, my
husband has had dermatologists who didn't even recognize that he had
eczema!) You may see it on infants too, they get it also. Here is
a photo of an infant with a nasty cases of eczema.
Other conditions
often get confused with eczema and then a dermatologist might just
say it is "contact dermatitis". What is known is that certain
triggers do seem to cause flare-ups. These include lower humidity,
lower temperature, and certain clothing like wool. Stress can make
any skin condition worse, whether it's eczema, psoriasis,
acne, herpes,
cold sores, etc. Psoriasis
sometimes resembles eczema, but usually the distribution will make
it more obvious. A family history of eczema may be present; and sometimes
a biopsy will be helpful. The best advice to give someone is to ward
off a flare-up if you can! Ask your parents if they have ever had
it if you do. See a dermatologist if it gets infected or if you are
unsure if it is eczema.
The first line
of defense usually is something to keep the skin from being this dry.
So we use what we call emollient creams or lubricating creams or ointments.
Traditionally, steroid creams or ointments were used for flare-ups,
but they had side effects when used long term. Often hydrocortisone
creams are used. I personally have not seen them to be very effective
with very itchy eczema. Non-steroidal preparations offer a treatment
that is not only effective but seems free of long term side effects.
That is the way to go if you can. There are also herbal treatments
that may work for you. Acupuncture has
been known to help eczema also.
Oral antihistamines
(like Benadryl®) can be used to reduce itching, which can be very
useful at night when patients are unable to control their urge to
scratch the skin. Ultraviolet light therapy also reduces itchiness
in some people.
A new class of
drugs for mild to moderately severe cases of eczema is called topical
immunomodulators, or TIMS. Studies have shown that these drugs improve
or completely clear symptoms in the vast majority of cases, and pose
little or no safety concerns. Elidel (pimecrolimus) and Protopic (tacrolimus)
are the only drugs in this class that are available thus far. Studies
with Elidel have shown that application of TIMs at the first sign
of itching can reduce severity and/or onset of flares.
What
To Do To When You Have Eczema?
1. Avoid drying or irritating the skin
2. No more than one shower or bath per day, and do not sit in a soapy
bath
3. Only use soap on armpits, groin, and feet
4. Uses soaps that dont dry out skin, such as Aveeno, Neutrogena,
or Cetaphil.
5. Pat skin dry after shower/bath -- do not rub it!
6. Before skin is completely dry, cover with an agent that helps hold
in moisture, such as Eucerin, or mineral oil. (I say avoid petroleum
products).
7. Avoid scratchy clothes (often cotton is the best)
8. Avoid foods that tend to trigger (do challenges to determine which
ones may trigger -- most common are wheat and dairy). Only 30% of
those affected are worsened by certain foods.
Remember, there is no cure for this very annoying condition, but ways
to manage it!
Decrease stress. Easy to say, harder to do.
