Oxalate – What Is It?

What is Oxalate?
6
• Oxalate is a naturally occurring molecule, containing two double bonded oxygens and two carbon atoms, found abundantly in plants. It can also be produced in humans and from various fungi.
• It is not a nutrient in humans and can lead to kidney stones in susceptible individuals.
• In plants, oxalate helps to reduce extra calcium.

What is Oxalate?
• Oxalate, and its acid form, is an organic compound obtained from three primary sources:
• Diet
• Fungus, such as mold and yeast
• Metabolism
• Oxalic acid is the most acidic organic acid in body fluids.
• Ethylene glycol (antifreeze) – toxicity effects are from oxalate crystal formation and acidosis.
• Pain on urination (but, no confirmation of infection)
• Eye pain (eye poking in some children)
• Body aches, burning feeling in muscles
• Fibromyalgia-like discomfort
• Moodiness, irritability, and aggressive behavior – often seen in autism.
• Tendon pain, trigger point tenderness, increased tension in muscles with movement.
Common Patient Complaints/Observations

YOUR LOGO
Vulvodynia
• It is a syndrome of unexplained vulvar pain, frequently accompanied by physical disabilities, limitation of daily activities, sexual dysfunction and psychological distress.
• The patient's vulvar pain usually has an acute onset and, in most cases, becomes a chronic problem lasting months to years.
• The pain is often described as burning or stinging, or a feeling of rawness and irritation.

• Cyclic vulvovaginitis is believed to be a reaction to yeast, which may be detected at times, and not detected at other times with KOH preparation or fungal cultures.
• Because of the link with Candida, treatment for cyclic vulvovaginitis may include anti-candida medication even if cultures are not positive.
• Other treatments for vulvodynia are a low-oxalate diet and the addition of oral calcium citrate (Citracal), two tablets (200 mg/950 mg each), two to three times a day.

Aspergillosis
• Aspergillosis is an infection caused by Aspergillus
• Most people breathe in Aspergillus spores every day without becoming ill. Individuals with weakened immunity or existing lung disease are at higher risk for Aspergillosis.
• The types of health problems caused by Aspergillus include allergic reactions, lung infections and infections in other organs.

Aspergillus Toxicity
• Most prevalent mold group in the environment and has caused billions of dollars in damage to crops and livestock.
• Most common Aspergillus mycotoxins are aflatoxin, ochratoxin, patuli and fumagillin.
• Aspergillus toxins have been found in all major cereal crops, e.g. peanuts, corn, rice.
• They can also be found in eggs, milk and meat from animals fed contaminated grains.
• There are approximately 180 species of Aspergillus, but fewer than 40 of them are known to cause infections in humans.
• Aspergillus fumigatus is the most common cause of human Aspergillusinfections. Other common species include A. flavus, A. terreus, and A. niger
• The liver is the main target of these toxins.

Solubility is the Factor That Determines Oxalate and Heavy Metal Toxicity
Salt Ksp (solubility product constant)
Mercury I 1.75 X 10-13
Lead 8.6 X 10-10
Copper II 4.4 X 10-10
Zinc 1.4 X 10-9
Cadmium 1.42 X 10-8
Calcium 1.5 X 10-8
Magnesium 8.5 X 10-5
The smaller the value of the Ksp, the greater insolubility of
the salt. For example, the lower the Ksp value for Mercury versus Calcium
means it is more insoluble -less likely to dissociate.
The larger the number in the negative exponent, the smaller the numerical value
52
The Mercury-Oxalate Salt is approximately 100,000K less soluble than Calcium-Oxalate.

Some Facts About Oxalate Chemistry
• At the pH of blood most oxalate is in the dibasic form.
• Oxalates can form salts with a wide variety of metals.
• Calcium levels in blood are relatively constant, but oxalates levels can vary widely.
• It is the oxalate level in the blood which tends to drive calcium (or other mineral/metal) oxalate crystal formation in tissues.

• Type I (PH1) - Primary Hyperoxaluria Type 1 is caused by the deficiency of the oxalate breakdown liver specific enzyme called alanine:glyoxylate aminotransferase (AGT):
• AGT is a Vitamin B6 dependent enzyme
• Leads to high glyoxylic acid which is then converted to glycolate by the enzyme GRHPR or to oxalate by LDH (lactate dehydrogenase).
• Elevated Oxalate and Glycolate (glycolic on the OAT).

• It is often less severe that Type 1 usually causing kidney stone damage versus end-stage kidney failure.
• Tend to see elevated Oxalate and Glycerate (glyceric on OAT).

SLC26A6 - It is an anion-exchanger expressed in the apical membrane
of the kidney proximal tubule,
the apical membranes of
the duct cells in the pancreas, and the villi of the duodenum
YOUR LOGO71
A model for the molecular mechanism of slc26a6 and NaDC-1 reciprocal regulation in epithelia. The apical slc26a6 and NaDC-1 are present in a complex to allow their interaction. The
interaction is mediated by the slc26a6 STAS domain and the NaDC-1 ICL1. When interacting, slc26a6 inhibits NaDC-1, while NaDC-1 activates slc26a6. The result is retention of citrate in the
filtrate and perhaps other luminal fluids to chelate part of the Ca2+ to allow safe oxalate excretion. When minimal oxalate excretion is required, the interaction between slc26a6 and
NaDC-1 relaxes to increase the activity of NaDC-1 and citrate absorption and salvage. Disruption of this regulation in disease states leads to Ca2+/oxalate stone formation.

Soy protein is probably not a good food for human-Linda Massey, Ph.D., at Washington St U.
• During their testing, the researchers found the highest oxalate levels in textured soy protein, which contains up to 638 milligrams of oxalate per 85-gram serving.
• Soy cheese had the lowest oxalate content, at 16 milligrams per serving.
• Spinach, measured during previous research, has approximately 543 milligrams per one-cup (2 oz. fresh) serving.

• Symptoms of oral ingestion: headache, muscle cramps and tetany (sharp flexion of the wrist and ankle joints, muscle twitching, cramps and convulsions), weak and irregular heartbeat, drop in blood pressure, signs of heart failure.
• Large doses rapidly cause shock, convulsions, coma and possible death.
• Mean lethal dose by ingestion of oxalates is 10-15 grams, but the lowest reported fatal dose of a related salt, potassium oxalate, was 5 grams.
• Amount of oxalates in spinach (two cups = 150 grams). A green smoothie is 15 grams, a potentially lethal dose

Remove Oxalate VERY SLOWLY From The Diet
• 5-10% per week
• For high oxalate patients, this could take a couple months or more.
• Removing them quickly can cause “dumping” symptoms, pain and can overwhelm the system.
Lynn Turner (July 13, 1968 – August 30, 2010), born Julia Lynn Womack, was an
American convicted murderer. In 1995, her husband, Glenn Turner, died after allegedly being sick with the flu. In 2001, the death of
what had been described as her common law husband, Randy Thompson, under
remarkably similar circumstances, aroused the suspicion of law enforcement. After
investigation, it was determined by authorities that Lynn Turner had murdered both her husbands by poisoning them with ethylene glycol-based antifreeze. She was
tried for Glenn Turner's murder in 2004. She was found guilty and went to trial again for
murdering Randy Thompson in 2007, ultimately being convicted. Turner died in prison on August 30, 2010. The cause of death was an apparent suicide by toxic overdose of blood pressure medication.
