Can Plant Oxalates Cause Neuropathy? Yes. Here’s a Neuro Lyme Comparison.

Yes, oxalates can potentially cause neuropathy, particularly in cases of oxalate accumulation or hyperoxaluria. Here’s an overview of the relationship between oxalates and neuropathy:

Oxalate-Related Neuropathy

1. Peripheral Neuropathy

Oxalate crystals can accumulate in peripheral nerves, leading to damage and dysfunction. This can result in symptoms such as pain, numbness, tingling, and weakness in the extremities.

2. Mechanism of Nerve Damage

Several mechanisms have been proposed for how oxalates cause nerve damage:

Disruption of axonal transport due to crystal deposition
Direct toxic effect of oxalate on nerve tissue
Nerve ischemia related to vessel occlusion from oxalate crystal deposition

3. Progressive Polyradiculoneuropathy

In severe cases, oxalate accumulation can lead to a rapidly progressive axonal and demyelinating sensorimotor polyradiculoneuropathy.

Symptoms of Oxalate-Induced Neuropathy

Patients with oxalate-related neuropathy may experience:

Sharp shooting pain
Dull aching pain
Severe muscle cramping
Sensory loss (stocking-glove distribution)
Weakness, particularly in distal muscles
Areflexia (absence of reflexes)

Associated Conditions

Oxalate-induced neuropathy is often associated with:

Primary Hyperoxaluria: A rare genetic disorder causing overproduction of oxalate.
Chronic Kidney Disease: As the kidneys are responsible for oxalate excretion, kidney dysfunction can lead to oxalate accumulation.
Systemic Oxalosis: A condition where oxalate deposits in multiple tissues throughout the body.

Diagnosis and Treatment

Diagnosis typically involves:

Clinical evaluation of symptoms
Nerve conduction studies
Biopsy of affected nerves (in some cases)
Genetic testing for primary hyperoxaluria

Treatment approaches may include:

Addressing the underlying cause (e.g., managing primary hyperoxaluria)
Dietary modifications to reduce oxalate intake
Kidney and/or liver transplantation in severe cases

It’s important to note that while oxalate-induced neuropathy is a recognized condition, it is relatively rare. If you’re experiencing symptoms of neuropathy, it’s crucial to consult with a healthcare professional for proper diagnosis and treatment.

Suggestions to Help Your Body Remove Oxylates in Nerves

To address oxalate crystals causing neuropathy once they have already accumulated in nerves and muscles, consider the following approaches:

Hydration and Fluid Therapy

Increase water intake to help flush oxalates from the body
In severe cases, intravenous fluid therapy may be necessary to promote oxalate excretion

Medication and Supplementation

Vitamin B6 (Pyridoxine): May help reduce oxalate production in the body
Calcium citrate: Can bind to oxalates in the bloodstream, potentially aiding in their removal
Antioxidants: May help reduce oxalate-related inflammation in nerves and muscles

Medical Interventions

Hemodialysis: In severe cases, particularly with renal failure, dialysis can help remove oxalates from the blood
Organ transplantation: In extreme cases of primary hyperoxaluria, combined liver and kidney transplantation may be considered

Supportive Therapies

Physical therapy: To help maintain muscle function and reduce pain
Pain management: May include medications or other interventions to address neuropathic pain

Monitoring and Follow-up

Regular blood tests to monitor oxalate levels
Neurological assessments to track progression or improvement of neuropathy

It’s important to note that once oxalate crystals have formed in nerves and muscles, complete removal can be challenging. Treatment often focuses on preventing further accumulation and managing symptoms. The effectiveness of treatments can vary depending on the severity and underlying cause of oxalate accumulation.

Always consult with a healthcare professional, preferably one experienced in treating oxalate-related disorders, for a personalized treatment plan. They may recommend a combination of these approaches based on your specific condition and medical history.

Primary Hyperoxaluria Type 1

Oxalate accumulation, particularly in cases of primary hyperoxaluria type 1 (PH1), can lead to a rapidly progressive axonal and demyelinating sensorimotor polyradiculoneuropathy. This condition is characterized by damage to multiple nerve roots and peripheral nerves, affecting both motor and sensory functions[1][3].

Mechanism of Nerve Damage

The proposed mechanisms of nerve damage due to oxalate accumulation include:

1. Disruption of axonal transport: Oxalate crystal deposition within nerve fibers can interfere with normal axonal transport processes[1].

2. Direct toxic effect: Oxalate itself may have a toxic effect on nerve tissue[1].

3. 1: Oxalate crystal deposition in blood vessels supplying nerves may lead to occlusion and subsequent ischemia[1].

Pathological Findings

Nerve biopsies in patients with oxalate-induced neuropathy reveal several characteristic features:

– Secondary demyelination
– Axonal degeneration
– Presence of calcium oxalate monohydrate crystals within nerve fibers[1][3]

Under polarized light microscopy, these crystals appear as bright hexagonal, rectangular, or starburst-shaped inclusions[1].

Clinical Presentation

The neuropathy associated with oxalate accumulation typically presents as:

– Rapidly progressive
– Affecting both sensory and motor functions
– Involving multiple nerve roots (polyradiculopathy)
– Characterized by both axonal damage and demyelination[3]

Association with Renal Disease

This type of neuropathy is often observed in patients with end-stage renal disease, particularly those with primary hyperoxaluria type 1 (PH1). The onset of severe neuropathy may coincide with the development of renal failure or initiation of dialysis[1][3].

Diagnosis and Management

Diagnosis involves a combination of clinical presentation, nerve conduction studies, and potentially nerve biopsy. Management typically focuses on treating the underlying cause of oxalate accumulation, which in PH1 may include combined liver and kidney transplantation. Some patients have shown significant neurological improvement following transplantation[3].

In conclusion, oxalate accumulation can lead to a severe and rapidly progressive form of peripheral neuropathy, particularly in patients with primary hyperoxaluria and renal failure. Early recognition and management of the underlying condition are crucial for preventing or limiting neurological damage.

Neuro Lyme Disease vs Oxalate Neuropathy – Key Distinguishing Factors

Symptoms

Oxalate Neuropathy:

Typically presents as a distal sensory neuropathy
Often involves neuropathic pain
May be asymmetric at onset
Can affect small fiber nerves

Lyme Neuropathy:

Can present with various neurological symptoms including:
- Numbness, tingling, and “shooting” pain in limbs
- Facial palsy (drooping on one or both sides of the face)
- Meningitis symptoms (fever, headache, stiff neck)
May involve cranial nerves, peripheral nerves, or central nervous system

Diagnostic Tests

Oxalate Neuropathy:

Serum oxalate levels
24-hour urine oxalate excretion
Nerve conduction studies and electromyography (EMG)
Small fiber nerve biopsy may be considered

Lyme Neuropathy:

Two-step serologic testing for Lyme disease (ELISA followed by Western blot)
Cerebrospinal fluid (CSF) analysis if central nervous system involvement is suspected
MRI may show white matter hyperintensities in some cases. (see Note)
Nerve conduction studies and EMG may be helpful

Note: In neurologic Lyme disease, MRI findings can vary between children and adults. Children may show white matter hyperintensities suggestive of inflammation or demyelination, while up to 40% of adults with Lyme disease may exhibit small white matter hyperintensities. However, these findings are not specific to Lyme disease and require careful interpretation. It’s important to note that the number of hyperintensities naturally increases with age, even in individuals without Lyme disease. Additionally, other factors such as ischemic disease or a history of smoking can contribute to an increased number of hyperintense areas on MRI. Therefore, while MRI can provide supportive evidence, it should be considered alongside clinical symptoms, patient history, and other diagnostic tests for an accurate diagnosis of neurologic Lyme disease[9].

Key Distinguishing Factors

History of tick exposure: Lyme neuropathy is associated with tick bites in endemic areas, while oxalate neuropathy is not.
Presence of erythema migrans rash: This characteristic expanding rash is often seen in early Lyme disease but not in oxalate neuropathy.
Serologic testing: Positive Lyme serology strongly suggests Lyme neuropathy, whereas it would be negative in oxalate neuropathy.
Response to antibiotics: Lyme neuropathy often improves with appropriate antibiotic treatment, while oxalate neuropathy would not.
Associated conditions: Oxalate neuropathy may be associated with conditions that increase oxalate levels, such as primary hyperoxaluria or excessive dietary oxalate intake.
Pattern of nerve involvement: Lyme disease can affect multiple nerves in various patterns, including facial palsy and radiculopathy, which are less common in oxalate neuropathy.
Timing and progression: Lyme neuropathy often develops within weeks to months after tick exposure, while oxalate neuropathy may have a more gradual onset related to oxalate accumulation over time.

Which Disease Better Fits These Symptoms

Based on the symptoms described, here’s an assessment of which disease (oxalate neuropathy or Lyme neuropathy) is more likely to cause each:

Microblood bleed in the eyeball near the fovea: Lyme disease is more likely, as it can cause ocular manifestations including retinal vasculitis.
Head buzzing vibrations: Lyme neuropathy is more likely to cause this sensation, as it can affect the central nervous system.
Stiff sore neck on movement: Lyme disease is more likely, as it can cause meningitis symptoms including neck stiffness.
Excess floaters: Lyme disease is more likely, as it can affect the eyes and cause various visual disturbances.
Visual migraines: Oxalate neuropathy is more likely, as oxalate accumulation can affect blood vessels and potentially trigger migraines.
Morning numbness of fingers and sometimes entire palm: Both conditions can cause this, but Lyme neuropathy is more likely due to its tendency to affect peripheral nerves.
Headaches: Both conditions can cause headaches, but Lyme disease is more likely, especially if associated with meningitis.
Fatigue: Both conditions can cause fatigue, but it’s a more common and prominent symptom in Lyme disease.
Non-pulsatile tinnitus: Lyme disease is more likely, as it can affect cranial nerves and cause auditory symptoms.
Slow heart rate during sleep: Lyme disease is more likely, as it can cause cardiac manifestations including heart block.
O2 desaturation to 88% during sleep: Neither condition typically causes this, but it could be an indirect effect of neurological involvement in Lyme disease affecting respiratory control.
Folliculitis: Neither condition directly causes folliculitis, but Lyme disease can cause various skin manifestations.
Circle hairs: Neither condition is directly associated with circle hairs.
Cherry angiomas: Neither condition is directly associated with cherry angiomas.
Pins and needles feeling in hands and feet: Both conditions can cause this, but it’s a more characteristic symptom of peripheral neuropathy in Lyme disease. Peripheral nerve involvement in Lyme disease can lead to radiculoneuropathy, which causes numbness, tingling, and other sensory disturbances in the extremities
Numb patches on toes, both feet: both Lyme neuropathy and oxalate neuropathy can potentially cause numb patches on toes and feet, but Lyme neuropathy is more likely to be the cause in this case. This type of neuropathy often affects the feet and can present as patchy areas of numbness. Oxalate neuropathy can also cause sensory symptoms in the feet, but it is more rare and typically presents as a more diffuse distal sensory neuropathy rather than distinct numb patches.

Overall, more of these symptoms align with Lyme neuropathy than oxalate neuropathy, suggesting Lyme disease as the more likely cause for this constellation of symptoms.
