Is eczema an autoimmune disease?

Does garlic boost the immune system?

Eczema is an itchy skin condition that can be painful and chronic. Eczema sufferers commonly have allergies and consuming a food you are allergic to elicits an IgE immune system response. The result is itchy, inflamed skin.

However avoiding your diagnosed allergy foods does not usually fix your eczema (or it only partially helps). So researchers in Vienna hypothesise that because the immune response can still occur after the allergy foods are avoided eczema “could be autoimmune” (Valenta 2009).

A drug company recently declared that “eczema is an autoimmune disease”. And they stand to profit greatly from their findings. Their patented drug will hit the market (if it passes safety tests) and again we will clamour for the promise of a quick fix, only to find the side-effects are worse than the original skin disorder.

Remember that topical steroids were once the miracle cure eczema sufferers were praying for. Topical steroid addiction has been known of since the 1970s and after using (and stopping) topical steroids your eczema can spread to areas where it previously did not appear. So tread carefully when it comes to taking new drugs for eczema – there is a safer way.

Is eczema an autoimmune disease?

Not usually… there is no conclusive evidence showing that eczema is always an autoimmune disease. Not everyone with eczema has allergies, not everyone with eczema has abnormally high levels of antinuclear antibodies in their blood. So it might be short sighted to categorise all cases of eczema as autoimmune.

Let’s look at the facts: eczema is not only related to allergies and immune-system imbalance, it’s also strongly linked with the following:

  • 17 to 33% of eczema sufferers have fatty liver (Kimata, 2001)
  • 52% are sensitive to salicylates (Loblay and Swain 2006)
  • 36% are sensitive to amines (amines are in probiotics) (Loblay and Swain 2006)
  • 35% react to MSG/glutamates (Loblay and Swain 2006)

A widely replicated major risk factor for eczema is also genetic dysfunction: namely the loss-of-function mutations in the structural protein filaggrin. Microbes and infections are also involved in the appearance of eczema.

All of these factors worsen eczema. Avoiding allergies is a good place to start but if it’s your only strategy to prevent eczema, then your skin problem is likely to prevail.

Liver health and eczema – the forgotten link

Dr Kimata from the Department of Pediatrics and Allergy at the Ujitakeda Hospital in Kyoto (Japan) 17% to 33% of children with eczema have non-alcoholic fatty liver. Your liver health is important to detoxify toxins and chemicals, and food sensitivities and allergies can result. So while treating allergies and the immune system is useful, we can also look at the underlying cause of allergies which is liver dysfunction and gut dysbiosis. 

Leaky gut is related to coeliac disease and gluten intolerance. Fatty liver can be caused by nutritional deficiencies, low antioxidants in your diet, and high sugar and high fat intake. Fatty liver is reversed with supplementation and a change in diet but scarring and damage can occur from frequent drug use.

“Should I avoid garlic as it boosts the immune system?”

Garlic is low in salicylates and it is one of the few flavourings people with eczema and salicylate sensitivity can enjoy. While garlic may not be suitable for everyone, many are fine with it. If you are allergic or sensitive to garlic then avoid it and if you have diagnosed autoimmune disease you can avoid using garlic if you have been instructed to do so.
I encourage people to omit anything they don’t like (from The Eczema Diet), but don’t avoid garlic unnecessarily.

“If I have eczema should I take drugs to suppress my immune system?”

My opinion differs to many medical professionals but most would agree that eczema is not an autoimmune disease. Some people with eczema also have autoimmune disease (i.e. an overactive immune system) but that is not the rule for everyone with eczema.

I have worked with eczema patients who have had overactive immune systems, which were overactive because they were eating foods they were highly sensitive to and they had nutritional deficiencies.

Long-term use of topical steroids can also cause problems, and often topical steroid withdrawal is involved and causes the eczema to be stubborn and hard to treat.

Their calcium levels were also very low and this caused insomnia (which caused more stress). Once these patients changed their diets and took Skin Friend supplements their immune systems gradually normalised. This took about 8 months.

For those with eczema and immune system issues, I find they need to be healthy long-term. For other eczema sufferers who have no autoimmune issues and no topical withdrawal symptoms, their eczema clears a lot faster.

“Is the immune system incompetent and should it be silenced with drugs?”

In most cases, no. The immune system is usually an intelligent mechanism which alerts us when something is not right within the body. Just because you cannot identify the trigger/s does not mean you should presume the immune system is faulty (of course it may be faulty in some cases but we cannot assume this in all cases of eczema).

Often a radical change in diet and environment, plus nutritional support are needed to get the body back in balance. Sleep and laughter also help eczema according to Japanese researcher Dr Kimata.

Changing the diet is hard work and some people like taking pills as it is the easy option. But drugs often come with side-effects and you need to weight up if the side-effects are worth the short-term relief.

Some people absolutely need to take immunosuppressant drugs in order to live without pain so I’m not saying never take the medical option. I’m saying do both if you have to. But do your research on side-effects first as the drugs can end up worsening your eczema symptoms in the long-term so what begins as mild eczema can end up covering your whole body.

A natural approach to eczema

At the Eczema Life Clinic in Sydney we see a lot of new eczema patients with symptoms such as loss of hair and eyebrows, cracks at the corners of their mouth, insomnia, itchy skin and chronic dry and flaking skin and these are common nutritional deficiency signs, that are easily reversed with the right supplementation.

The Eczema Diet and the Skin Friend supplements were initially designed for my two-year-old daughter who had eczema. I no longer wanted to use topical steroids and a nurse had advised us to avoid salicylates (which are in most supplements, in ingredients such as herbs and fruit extracts).

After following the diet and taking the supplements for about 3 months, patients have reported renewed hair growth, less inflammation, softer skin, healing of mouth ulcers and cracks around the mouth, and their skin is no longer itchy.

When you change your diet you are changing your body’s biochemistry, improving your genetic health and normalising your immune system – this does not happen overnight. We need to change our mentality about seeking quick-fixes for eczema. Take the time to feed your skin from the inside out – you’ll look and feel better for it.
