What Is Pyrrole Disorder?

Pyrrole Disorder is an alternate name for the condition known as Pyroluria, which is also known by various other names including Kryptopyrrole, Kryptopyrroluria, Pyrroluria, Pyrolle Disorder, Mauve Factor and Hemepyrrole.

Pyrrole Disorder is the abnormal synthesis and metabolism of any heme producing molecule, including the oxygen-carrying molecule hemoglobin. All cells in the body consume nutrients and they also produce waste or by-products. The by-product of heme metabolism is a metabolite called hydroxyhemopyrrolin-2-one (HPL), AKA Mauve Factor. Originally HPL was thought to be the molecule Kryptopyrrole, but further studies have proven this is not to be the case.

Pyrrole Disorder sufferers produce excessive amounts of HPL, which renders the receptors on cells unable to utilize Zinc 1-8, Vitamin B6 1-8 and Biotin 9 while enhancing their excretion in the urine. HPL also prevents the proper manufacture of an important Omega 6 fat, Gamma Linolenic Acid (GLA).

Supplementation with these nutrients is essential to reduce the detrimental effects of elevated HPL and to reduce the severity of the symptoms and signs linked to Pyrrole Disorder.

There is some evidence that suggests Pyrrole Disorder is genetically based, especially if a parent, grandparent, aunt, uncle, brother or sister has suffered from major Depression, Bi-Polar Disorder, Alcoholism, Schizophrenia or has committed suicide.

What we have found through treating many sufferers of Pyrrole Disorder, is that certain lifestyle factors also contribute to, or exacerbate, the many associated signs and symptoms of Pyrrole Disorder. Addressing stress, improper diet, inadequate digestion, dysbiosis and leaky gut syndrome are essential in any treatment protocol for Pyrrole Disorder.

Poor diet and/or poor digestive health can lead to an increase in HPL levels 10. This makes sense as insufficient nutritional intake from a poor diet and malabsorption stemming from inadequate digestion, robs the body of essential nutrients creating deficiencies. These deficiencies, in turn, place a greater stress on the body, thus further increasing HPL levels.

Leaky Gut Syndrome or intestinal permeability is a condition whereby microscopic holes appear in the intestinal wall allowing bacterial by-products, food particles, poisons and toxins to pass into the bloodstream. Unfortunately, Leaky Gut Syndrome is commonly found in people suffering from Pyrrole Disorder and contributes to further elevation of HPL.

Studies have shown that zinc deficiency increases Leaky gut Syndrome in both animals and humans. 11-17 Stress is a major contributor to intestinal inflammation, which in turn increases the severity of Leaky Gut Syndrome. 10,18-20

Dysbiosis, also commonly found in Pyrrole Disorder, is an overgrowth of detrimental organisms and an undergrowth of the beneficial ones within the intestinal tract. Dysbiosis is linked to high HPL levels as well as a major cause of Leaky Gut Syndrome. 21, 22 Stress has been shown to increases the adherence of bad bacteria to the intestinal wall within 30 minutes further worsening Dysbiosis and Leaky Gut Syndrome. 23

Pioneering Pyrrole Disorder researcher, Dr Carl Pfeiffer, stated on more than one occasion that stress is a major driver behind elevated HPL. Further research confirms this and has shown that elevated stress levels can indeed increase the production of HPL 2,6,24. A non-published US navy study conducted in 1992 found a very rapid increase in HPL levels in healthy male volunteers who were subjected to the stress of a brief cold-water immersion 10.

Heavy metal exposure, smoking, drugs (medical or recreational) and alcohol can also increase HPL levels. This is why the symptoms of Pyrrole Disorder sufferers tend to get a worse for 24 to 72 hours after a big night out drinking or after recreational drug use.

What Damage Does Pyrrole Disorder Metabolite HPL Cause?


HPL is classed as a 'nerve poison’ 25 and as such it can cause damage to nerves, nerve cells, tissue, the brain and also interrupt messages being sent along neuronal pathways especially within the brain.

Heme is a substance found in the body and has an iron atom at its core. The most commonly know heme molecule is hemoglobin, the oxygen-carrying red pigment of the blood. Heme is present in the liver, nerves and antioxidant enzymes.

The metabolic activity of nerves is highly dependent on heme for their function, and low levels of heme can lead to a metabolic crisis, resulting in neuronal or nerve cell death 26-28. The by-product of heme metabolism, HPL, is believed to further decrease heme levels in humans, thus worsening many of the signs and symptoms associated with Pyrrole Disorder.

Animal studies showed that HPL caused a decrease in liver heme and the heme-containing detoxification enzyme cytochrome P450, by up to 55% over a 48 hour period 29. Zinc, Vitamin B6, and Biotin are required for the production of heme and as such a reduction in these nutrients results in abnormal heme levels 27,30.

Heme is further depleted by stress and heavy metal exposure 27. Low levels of heme result in the excessive production of nitric oxide, which can cause serious damage to brain tissue and is suspected to play a role in schizophrenia, autism and Down Syndrome 31-35.

Oxidative stress or free radical damage can impair, injure and degenerate cells. Antioxidants are substances found in natural foods and are produced by the body to protect cells from damage, much like the way galvanized paint protects iron from rusting.

The body has three major antioxidant enzymes; Glutathione, Catalase and Superoxide Dismutase. All three of these enzymes rely on zinc or vitamin B6 in some part to assist in their production.

A marginal deficiency of vitamin B6 is linked to lower levels of Glutathione and cell mitochondrial decay 36-38. Catalase consists of four protein subunits, each requiring heme and as HPL suppresses heme, we can assume that Pyrrole Disorder is associated with lower catalase levels, as is the case with schizophrenia and autism 39-41. For Pyrrole Disorder sufferers the greater the HPL, the higher the level of oxidative stress.

Pyrrole Disorder: The Statistics

The following table shows neurological and behavioral disorders along with the percentages of high HPL associated with those disorders (10).

 Diagnosed Ailment
 % of HPL
 Diagnosed Ailment
 % of HPL
 Acute Intermittent Porphyria
 100  Down's Syndrome
 Latent Acute Intermittent Porphyria
 70  Schizophrenia Acute
 59 - 80
 Manic Depression
 47 - 50
 Schizophrenia Chronic
 40 - 50
 Depression (Non Schizophrenic)
 12 - 46
 Epilepsy  44
 Autism  46 - 48
 Learning Difficulties
40 - 47
 40 - 47
 Criminal Behavior
 Neurosis  20  - Adults With Sudden Deviance
 20 - 84
 - Youths, Violent Offenders

The reason for the variance in some of the above figures is that it depends which study the results have come from. For example one study may have found only 20% of alcoholics had high levels of HPL, whereas another study found that 84% of alcoholics had high levels of HPL.

Why Isn't Pyrrole Disorder Accepted by Mainstream Medicine?

Regrettably Pyrrole Disorder falls outside the realm of mainstream medicine because the only way to rectify the problem is by improving the sufferer's nutritional status, digestion, diet and stress levels. Thankfully there are a small group of GP's endeavoring to change this.

Mainstream medicine relies on drugs to suppress symptoms or relieve suffering. This form of treatment will not work on a person suffering from Pyrrole Disorder. Unfortunately Pyrrole Disorder sufferers tend to fall through the cracks of mainstream medicine, are often misdiagnosed and given medication that does nothing to rectify the underlying problem. Sadly these medications can lead to further deterioration of a person's health.

Already diagnosed with Pyrrole Disorder....unsure what to do next?

We have a variety of options available;

1) Our Adult and Child, Positive and Borderline Pyroluria Treatment Plans (Pyrrole Disorder Treatment Plans) offer the latest up to date treatment information and contain advice and recommendation on nutritional supplementation, diet, lifestyle issues and the underlying causes.

2) Our Pyroluria Combo Packs (Pyrrole Disorder Combo Packs) are for adults and children diagnosed with Positive or Borderline Pyrrole Disorder and contain our recommended Treatment Plan and the nutritional supplements. This is a more economical way of purchasing nutritional supplements for the first 4 - 8 weeks of Pyrrole Disorder treatment.

As you can see Pyrrole Disorder is a complex health issue and treatment with the relevant nutrients will help to reduce the symptoms associated with Pyrrole Disorder, but it will not address the underlying causes. Any treatment protocol for Pyrrole Disorder needs to not only support the nutritional deficiencies, but also identify and treat what has caused Pyrrole Disorder in the first place.
