Kryptopyrroluria (KPU)

By Dr S V Bulatov – registered homeopath

 KPU is a controversial metabolic condition characterized by the excessive urinary excretion of pyrroles, which bind to and deplete essential nutrients—specifically zinc, vitamin B6, biotin, etc.

 The pyrrole is a colourless, volatile, heterocyclic aromatic organic compound. A five-membered aromatic ring with four carbon atoms and one nitrogen atom. Weakly acidic, as the nitrogen lone pair is part of the aromatic electron system. It darkens upon exposure to air and has a boiling point of 129 °C. Pyrrole derivatives are found in natural products like antibiotics.

 This is a genetic condition caused by a defect of several enzymes needed for the synthesis of heme - the building block of hemoglobin that delivers oxygen to the cells and cytochrome P450 oxidases that detoxify the body.

 The heme is an essential iron-containing porphyrin complex that acts as a vital prosthetic group for proteins like haemoglobin, myoglobin, and cytochromes. It is critical for oxygen transport, cellular respiration, ATP generation, and signal transduction. Primarily synthesized in the bone marrow and liver, heme is also a highly bioavailable form of dietary iron found in meat, fish, and poultry. The heme facilitates gas exchange (oxygen transport), acts as a redox catalyst in enzymes (catalase), and helps in electron transport chains. Lack of heme synthesis impacts blood, liver and nervous system. 

 The cytochrome P450 (CYP450) enzymes are a large family of heme-containing proteins primarily found in the liver that metabolize drugs, toxins, and endogenous compounds. They perform Phase I metabolism, breaking down, activating, or detoxifying over 90% of commonly used medications. Key enzymes include CYP3A4, CYP2D6, and CYP2C9. These enzymes primarily catalyse the oxidation of organic substances, making drugs more water-soluble for excretion. Medications can be substrates (metabolized by), inducers (increase enzyme activity), or inhibitors (decrease activity) of CYP450 enzymes, leading to significant drug-drug interactions. Polymorphisms in genes encoding these enzymes can lead to different phenotypes (poor to rapid metabolizers), causing large differences in how individuals respond to standard drug doses. Found in the endoplasmic reticulum of liver cells, though also present in the intestine and kidneys. While 57 isozymes exist, 6—CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4—are responsible for the vast majority of drug metabolism.

 KPU can be induced by:

1. Psychological trauma
2. Chronic infections, especially chronic Lyme disease
3. Intrauterine/birth/childhood/trans generational trauma
4. Car accident
5. Emotional trauma
6. Physical and sexual abuse

 Increased levels of circulating pyrroles bind with zinc, vitamin B6, biotin, manganese, arachidonic acid and other nutrients, excreted via the kidneys. This causes severe deficiencies.

 The zinc is an essential trace mineral vital for immune function, protein synthesis, DNA creation, and wound healing. It acts as a cofactor for over 300 enzymes and is crucial for growth and sensory functions. Zinc boosts the immune system by aiding T-cell production, supports metabolism, maintains skin integrity, and aids in sensory functions like taste and smell.

 The vit B6 is a vital water-soluble nutrient necessary for metabolism, brain development, immune function, and hemoglobin formation. It helps regulate mood, reduce pregnancy-induced nausea, and prevent deficiencies that cause skin rashes and neurological issues. Involved in over 100 enzyme reactions, mainly protein metabolism, cognitive development, and maintaining normal homocysteine levels. Helps create neurotransmitters like serotonin and dopamine. May interact with phenytoin (seizure medication) and blood pressure medications. 

 The biotin (vit B7) is a water-soluble essential nutrient crucial for energy metabolism, converting fats, carbohydrates, and proteins into fuel. It promotes healthy hair, skin, and nail growth, and supports nervous system function. While deficiency is rare, it can cause hair loss and skin rashes.

 The manganese is a crucial cofactor for enzymes like superoxide dismutase (SOD), which protects cells from free radical damage. It supports metabolism (protein, cholesterol, carbohydrate), immune function, blood sugar regulation, and bone development. It also helps with collagen production for wound healing.

 The arachidonic acid (ARA) is a 20-carbon polyunsaturated omega-6 fatty acid crucial for cell membrane structure, signalling, and inflammatory responses. It acts as a precursor to pro-inflammatory mediators, including prostaglandins, leukotrienes, and thromboxanes. ARA is a crucial component of phospholipid bilayers in cell membranes (especially in the brain, liver, and muscles), maintaining fluidity and integrity. It is essential for muscle repair, growth, and immune system function. It is also vital for foetal and infant development. ARA is metabolized via cyclooxygenase (COX) and lipoxygenase (LOX) pathways, producing eicosanoids that manage inflammation. While necessary for initiating acute inflammation and healing, excessive levels may promote chronic inflammation. It serves as a precursor for endocannabinoids, which influence pain, stress responses, and mood. 

While essential in small amounts, an overabundance of ARA relative to omega-3 fatty acids can contribute to chronic inflammatory conditions.

 The glutathione is a tripeptide made of the amino acids: glutamine, cysteine, and glycine. It is an antioxidant in humans, plants, animals, fungi, some bacteria and archaea. It is produced by the liver and involved in many body processes. Glutathione is involved in tissue building and repair, making chemicals and proteins needed in the body, and in the immune system function. Glutathione exists in reduced (GSH) and oxidized (GSSG) states. The ratio of reduced glutathione to oxidized glutathione within cells is a measure of cellular oxidative stress where increased GSSG-to-GSH ratio is indicative of greater oxidative stress. The people with KPU also suffer from low glutathione level that slows down detoxification.

 Key symptoms: Poor tolerance of physical and emotional stress, poor anger control, emotional mood swings, behavioral disorders, addictions, autism, Asperger’s, ADHD, ADD, Parkinson’s, depression, bipolar disorders, assaultive/aggressive/violent/criminal behavior, schizophrenia, anxiety, delusions, hallucinations, paranoia, occasional loss of contact with reality, tendency to have an insight (understand they have mental problems), poor short term memory, poor dream recall, prefer not to eat breakfast, upper abdominal pain when stressed, stitch in their side if they run, tendency to become loners as they age, mental symptoms are aggravated when undergoing stress, sweet, fruity breath and body odor, general loss of appetite, motion sickness, pain, seizures, complete physical debilitation, frequent infections, inability to tan, abnormal fat distribution, light, sound, odor and touch over sensitivity, hypoglycemia, pale skin, tremor, shaking, spasms, white spots on the nails, environmental and food allergies, cold hands or feet, stretch marks, tiredness, anemia, retention of heavy metals and environmental toxins, acne, amenorrhea, irregular periods, delayed puberty, impotence, eosinophilia, constipation and bloated feeling.

KPU flares up when the individual is undergoing prolonged stress, such as during a chronic and debilitating illness.

 Treatment: Taking zinc, vit B6, etc. for life adjusted according to the metabolic type, microbiological terrain, age and pyrroles level in the urine.

Methyl reconstruct is one of the best options to counteract the genetic defect and restore the balance in the body.

Eating nuts, legumes, green leafy vegetables, eggs (if no allergy/intolerance), chicken (if not B and AB blood group) and butter (if no cholesterol ring in the iris and elevated lipoprotein a) is also very helpful.
