The link between Chronic Kidney Disease and Coeliac Disease

https://www.fau.eu/2017/08/07/news/research/important-messenger-substances-in-the-immune-system/

Coeliac Disease might not be one of the first things that comes to mind when we hear the term “Chronic Kidney Disease”, but there are some interesting links between the two diseases, and the increasing incidence of Coeliac Disease globally makes this a topic worth discussing, especially for those of you who have been diagnosed with either disease, or have a family history of them.

 

Coeliac Disease is on the rise…

The estimated rate of Coeliac Disease worldwide is 1%. That’s 1 in every 100 people. The fact that this rate is increasing and that there is a strong genetic link suggest that we can expect this figure to rise. The fact that we do not understand the mechanisms responsible for this increase means there is not a lot we can do at this stage to prevent it.

 

CD vs CKD…

Coeliac Disease is a complex and as yet not well understood autoimmune disease, however the predisposing factors are clear. Sufferers must experience a combination of genetic, immune and environmental factors for the disease to develop. It cannot develop without dietary exposure to the protein gluten, and can only be managed by removing this trigger.

 

Chronic Kidney Disease, although the majority of cases can be attributed to high blood pressure and diabetes, can develop as a result of many different factors, including autoimmune conditions, urinary tract infections, congenital malformations (meaning they are present at birth), physical obstructions of the urinary tract or prostatitis, and many other inflammatory and genetic conditions. Diet and nutrition can be of great benefit in reversing kidney disease as we know, but it is rarely the direct cause of the condition.

 

The conditions do not appear related do they? But a cohort study published by Nephrology Dialysis Transplantation, which investigated the link between any form of glomerulonephritis, dialysis treatment and kidney transplantation and Coeliac Disease, has found statistical significance associating CD with an increased risk of Glomerulonephritis and renal failure.

On the surface, the 2 diseases appear to be completely unrelated, so let’s look below the surface…

 

What are the links between the diseases?

In a nutshell, it appears that immune characteristics are at the core of the connection between these 2 common and very serious diseases.

There is currently a lot of scientific interest in the gut (our gastrointestinal tract), it’s mechanisms of immune regulation and that factors of modern life that present a threat to the delicate balance that it serves to maintain. In the gut resides the gut-associated lymphoid tissue, or GALT. This makes up around 70% of our body’s immune cells – 70%! If this balance is compromised therefore, so is our immune system and its’ ability to protect us from disease. I will not go into too much depth about the role of GALT in this article, and to be honest there is still an awful lot we do not yet know about what goes on in there! But here is what we do know about the gut, and the similarities that have been found between Coeliac Disease and Chronic Kidney Disease sufferers.

 

Activated Immune System 

The mucosal immune system exists in the lining of the gastrointestinal tract and serves as our first line of defence against harmful pathogens, just as our skin does. It is an entire ecosystem made up of a complex network of immune cells and beneficial bacteria. Like any ecosystem, it relies on adequate nutrition, hydration and other factors to thrive and maintain homeostasis, or ‘balance’. When this barrier is compromised, protective mechanisms are initiated, one of which is the production and secretion of Secretory Immunoglobulin A (IgA). Almost 100% of Coeliac Disease patients have these antibodies present, and it appears that this same mucosal immune mechanism is also active in many forms of glomerulonephritis.

Gut permeability 

Tight junctions are part of the structural component of the mucosal immune system in the gut wall. They prevent toxins and harmful bacteria from entering the blood stream. Essentially, it’s what separates our internal environment from the outside world, so it’s pretty important! If these tight junctions are damaged, unwanted pathogens enter the systemic circulation and cause inflammation and oxidative stress throughout the body. This has been linked, as both a cause and effect, to generalised autoimmune diseases including Coeliac Disease.

Studies have shown that a loss in kidney function can also reduce the effectiveness of the intestinal barrier, allowing pathogens to enter the bloodstream and potentially increase the decline of kidney function. Conversely, an impaired intestinal barrier can potentially lead to autoimmune kidney diseases in susceptible individuals due to the inflammation and oxidative stress caused by the failure of the body’s first line of defence.

Auto-antibodies 

What are auto-antibodies you ask? These are similar to the antibodies our immune systems produce to fight invading pathogens, but autoantibodies are produced when the immune system mistakenly identifies its’ own tissue as the foreign invader. Auto = Self. This is what happen in autoimmune disease. Being an auto-immune condition, auto-antibodies are raised in Coeliac Disease, and studies have shown the same auto-antibodies to be present in renal disease.

What are the main threats to our internal environment?

  • Overuse of antibiotics and mediations
  • Stress
  • Chemicals in our food, water and environment
  • Pathogenic bacteria from food water and the environment
  • Poor diet
  • Genetics
  • Methods of birth and infant feeding

In Conclusion…

As with CD, the incidence of end stage kidney disease is on the increase globally, the underlying causes of which are still largely unknown. Many other chronic, autoimmune and immune related conditions are also on the rise. There are of course theories which speculate on this phenomenon, such as industrialisation, the hygiene hypothesis, overuse of antibiotics, the quality and preparation of the modern diet, stress and infections to name a few, but at the end of the day there are no definitive answers and therefore no definitive solutions.

With the growing body of evidence linking the gut to a myriad of health conditions, looking after our internal ecosystem seems like a pretty logical place to start in preventative health and disease management though. Don’t you agree?

Preventing and Treating Urinary Tract Infections – Naturally

Urinary Tract Infections, or UTI’s, are one of those annoying and embarrassing things that people don’t really like to talk about too much, but they are surprisingly common. In fact they are estimated to affect around 150 million people worldwide every year!

I would like to discuss how to prevent UTI’s because as well as being extremely uncomfortable, they can pose a threat to the kidneys. Even in an uncomplicated UTI (that is one where there are no other abnormalities of the urinary system), there is a likelihood that the bacteria will travel further up the urinary tract into the kidneys, but in complicated UTI’s (where there are other issues relating to the urinary system including renal disease), infections become more likely.

The most common symptoms of a UTI are feeling like you need to urinate more often, a painful burning feeling after urinating, getting up during the night to urinate, and smelly or cloudy urine. If there is fever, shakiness or lower back pain, this may indicate the infection has spread to the kidneys, in which case urgent medical attention is needed.

Often, antibiotics are prescribed to treat UTI’s, which usually gets rid of the infection and symptoms, but unfortunately antibiotics also negatively affect the good bacteria which actually help protect us from unwanted bacteria. This imbalance in bacteria then creates an environment that is favourable to drug-resistant pathogens, and so recurrence of UTI’s can become a vicious cycle.

Sometimes antibiotics cannot be avoided, but here are some tips and strategies to give you the best chance of avoiding needing them , and hopefully avoiding contracting a UTI I the first place:

Tips & Strategies 

Hygiene – UTI’s are more prevalent in women which is why some of these tips are specific to women’s hygiene.

  • Wiping from front to back after using the toilet
  • Empty the bladder fully
  • Wearing cotton underwear and avoiding tight clothing around the area
  • Always urinate as soon as possible after intercourse

 

Protect and support the microbiome – Several strains of probiotics have been researched and shown to be beneficial by promoting resistance to UTI’s by stimulating immunity. There are many different brands and combinations of strains available now, but look out for these strains on the bottle:

  • Lactobacillus plantarum HEAL9
  • Lactobacillus paracasei 8700:2
  • Lactobacillus rhamnosus LGG
  • Saccharomyces cerevisiae
  • Bifidobacterium animalis spp lactis.
  • Lactobacillus rhamnosus GR-1
  • Lactobacillus reuteri B-54

 

Herbal Medicine – There are many herbal medicines that can help support immunity and prevent and treat UTI’s. Herbal teas can be extremely effective as well as they go straight to the place we want them to! Try your local health food store to see if any of these are available.

  • Astragalus – Immune enhancing and diuretic, this herb supports the immune system and increases urine flow to eliminate bacteria.
  • Echinacea – This well-known herb can be used to help support the immune system as well as reduce inflammation and soothe irritated tissues in the urinary tract.
  • Corn Silk – This herb soothes the mucous membranes of the urinary tract as well as increasing urine flow. Even using the silk straight from a cob of corn steeped in hot water can help in an emergency!
  • Couch Grass – Another wonderful soothing and diuretic herb to help prevent bacteria accumulating and promote healing.
  • Buchu – Buchu is a urinary antiseptic which gives is amazing properties from preventing and treating UTI’s.
  • Shepherd’s Purse – Another urinary antiseptic, this herb also has anti-inflammatory properties which make it a valuable treatment.
  • Medicinal mushrooms – Not all mushrooms are created equal! These varieties enhance immunity and help prevent recurrent infection. Some of the best are Reishi, Cordyceps and Coriolus.

 

Support immune health through diet –

  • Vitamin C and zinc help decrease the severity and duration of an infection as well as help heal the tissues and prevent scarring. Citrus fruits, kiwifruit, capsicum, nuts and seeds are some of the best wholefood sources of these nutrients, but you may also want to supplement during periods of illness to support healing and recovery.
  • Avoid sugar! Sugars and refined carbohydrates can impair immune function and feed bacteria. Sugar also created an acidic environment that bacteria thrive in.

 

Prevent bacteria from adhering and colonising –

  • The bacteria that is present in a UTI thrives in the acidic environment. Keeping the urine alkaline during an infection will help stop the bacteria from colonising and spreading. There are commercial urinary alkalisers available, but in an emergency you can also drink ½ – 1 teaspoon of bi carb soda (not baking soda), in a glass of water 3-4 times per day.
  • Cranberry – Another herbal medicine that has been shown to prevent the bacteria from adhering to the wall of the urinary tract is Cranberry. You can take this in juice form, but avoid juices with sugar added (cranberry is quite tart!) as the sugar will feed the bacteria. If you are prone to UTI’s or kidney stones, you might want to take a quality cranberry tablet regularly instead as a preventative measure.

 

Flush toxins out of the urinary system –

  • As simple as it sounds, drinking enough water is the most important thing you can do to help prevent and resolve a UTI. Without adequate water, the bacteria will simply not leave the urinary system. How much you need to drink depends on several factors including body size, climate and whether or not you are a dialysis patient, in which case you need to discuss this with your doctor. For those who do not have a restriction on their water intake though, at least 2 litres per day is a good amount to focus on.

 

**As with any herbal medicines, make sure you talk with your doctor or pharmacist if you are taking any other medications.

What Everybody Ought to Know About Cadmium Toxicity and Renal Failure

A long, long time ago when man was inventing the wheel… nature provided us with pristine surroundings and atmosphere. We drank from the crystal blue waters, ate ‘organic’ fruit and vegetables, and rested in unspoiled lands.

…How so much is changed. Yes, we have progressed in terms of no longer defecating where we eat. Instead we have raped and pillaged all of the earth; her rivers, lakes, oceans, forests, deserts, and anywhere else we can find*.

As a consequence we now live in a toxic environment that compared to 100 years ago, would completely exceed imagination. Lift a bottle of water to our mouth… bring in dangerous xenoestrogen plastics. Apply our daily antiperspirant… introduce the heavy metal aluminium. Breathe in a full breath… hello arsenic.

Before this turns in to one of those “the sky is falling” type blog posts, let me digress and say:

“Whether you like it or not, your environment is affecting your health; but you do have the power to control it.”

And one of the biggest problematic elements found on earth for kidney sufferers is the heavy metal cadmium. Cadmium is one of the ‘big’ four heavy metals that are associated with the biggest threats to human health. The other three include: lead, mercury, and arsenic.

Heavy metals are routinely studied by large international bodies (such as the World Health Organisation – WHO) to determine their affects on human health. As such, much data and evidence has shown that these heavy metals exert powerful, though destructive, biological effects on the human body.

Cadmium in particular is an easy one to be exposed to due to the nature in which it is used. Nickel-cadmium batteries are mass produced and shipped to all four corners of the Earth – where you are probably using some right now. Cadmium industrial emissions are also very high, due to the fact that most cadmium products are uncommonly recycled. And cadmium exposure is profoundly increased in those who smoke cigarettes (cadmium is found in tobacco).

So What Are The Main Sources of Cadmium?
• Cigarette smoke (inc. passive smoking)
• Batteries (nickel-cadmium)
• Paint
• Evaporated milk
• Ceramics
• Shellfish
• Electroplating (Electronics)
• Drinking water (galvanised pipes)
• Phosphate fertilisers
• Breathing contaminated air in the workplace
• Fungicides
• Pesticides
• Tools
• Plumbing alloys
• Photographic chemicals

I am sure you are wondering by now…

“So How Does Cadmium Affect The Kidneys?”

Well, studies have shown that long-term exposure to cadmium via the food, water, or air, builds up in the kidneys and can possibly cause kidney disease and kidney failure via a number of pathways. A 2003 study in New Zealand (using mice) showed that in as quickly as 4 weeks of exposure there was an increase in antinuclear antibodies (=immune system). And on top of that, after 31 weeks on a low dose, increases in IgG2a (=immune system) were also noted. This brought about increased levels of protein in the urine and continued presence of immune bodies in the kidneys; indicating a kidney linked auto-immune disease (e.g. glomerulonephritis).

Is Inflammation Driving Your High Blood Pressure? Find Out for Sure…

Renal Hypertension

For many of you with hypertension (aka high blood pressure), a fire is burning intensely within you, which must be extinguished. Inflammation is the cause of many illnesses, and studies now point towards inflammation as a key trigger and driver for high blood pressure – the second biggest cause of kidney disease after diabetes.

If you haven’t already gathered, treating the cause of your illness is rule number one for healing yourself from renal disease (and any disease for that matter), so excuse when I repeat myself 5 billion times on this one…

“Treat the cause, not the symptoms. Treat the person, not the disease.”

So when I came across this study, I just had to show you. The results weren’t just suggestive, they were straight out conclusive! (Study: JAMA December 10, 2010, Vol 290. No. 22 2945)

A group of researchers came together to observe whether C-reactive protein (= a marker of systemic inflammation) is linked to high blood pressure. C-reactive protein has already been connected with the increased likelihood of myocardial infarction (= heart attack) and stroke, so the dangers to the cardiovascular system is already well established. On a side note: inflammation has also been associated with the development of diabetes, gastrointestinal disorders, dementia, increased aging, arthritic conditions, skin disorders, immune dysfunction, and many more.

The Setting
The study began by taking blood samples from 20,525 people with normal blood pressure. 7.8 years later they measured the same individuals again, and discovered that now a quarter of them had high blood pressure (5,365). C-reactive protein was then tested and shown to be significantly associated with an increased risk of developing high blood pressure.

They concluded “C-reactive protein levels are associated with future development of hypertension, which suggests that hypertension is in part an inflammatory disorder.”

The CAUSE of Your Kidney Disease is the KEY to Your Healing

This may seem a blatantly obvious statement to make to many people, but I am surprised time and time again how often this overlooked when treating ones health. But then again, this maybe second nature to me as throughout my naturopathic studies I was always told, verbatim: “treat the person, not the disease, treat the cause, not the symptoms”.

For example, this is most obvious when you slice your finger with a knife; you do not try and remedy the situation by increasing the strength of your skin so it can withstand knife penetrations do you? (I hope not, as that would be a little crazy!). No, you try and slice with more accuracy, because it was the handing of the knife that was the cause of the cut, not the skin being too weak.

The same can be said for let’s say, using pain medication for a headache. Are you treating the ‘headache’? Think about it. Or are you really inhibiting the ‘pain’.

A good question to ask before you ever treat yourself is “what am I trying to achieve here?”.

If you are trying to receive quick relief from the pain, then yes this is a VERY wise thing to consider, otherwise, if you are trying to heal, cure, or remedy the headache then you are entirely going about it the wrong way.

Though the solution to the cause of the headache maybe a tricky one to work out initially – as there are many possible causes: magnesium deficiency, spinal problems, estrogen dominance, high blood pressure, heavy metal toxicity, neurological disorders, just to name a few – it ALWAYS results in lifelong healing. Well worth the time and investigation, I believe.

…You see, when you realise the cause of YOUR kidney disease, you will be freed from its hold on you. And it won’t stop just at your kidneys, your whole body & life will be transformed by the flow on effect.

“Ones’ health displays the law of ‘cause and effect’ with perfection”

Take diabetes for example, the number one cause of kidney disease in the world, do you believe just treating the kidneys will be enough to heal them permanently if you leave your diabetes unchecked?
