Medical Marijuana and Mucopolysaccharidosis (MPS)

Nobody wants to receive a diagnosis of a severe health condition, especially mucopolysaccharidosis, which can cause a whole range of symptoms and other problems, along with having limited treatment options. However, as an alternative treatment, cannabis for mucopolysaccharidosis packs quite a punch with its ability to alleviate many diverse symptoms, including those of mucopolysaccharidosis.

What Is Mucopolysaccharidosis?

Mucopolysaccharidosis (MPS) is a group of inherited disorders where your body can’t properly break down chains of sugar molecules called mucopolysaccharides. Because of this, these sugars begin building up in blood, cells and connective tissue, leading to various health problems.

The treatment you receive will depend on the symptoms you’re experiencing.

Types of Mucopolysaccharidosis

There are seven different types and several subtypes of MPS.

Mucopolysaccharidosis Type I

Depending on symptom severity, health professionals separate MPS I into three main clinical entities:

1. Hurler syndrome (MPS 1-H) is the most severe type of MPS. It’s a progressive condition with multiple organ and tissue involvement that leads to early childhood death.

2. Scheie syndrome (MPS 1-S) is the mildest type of MPS. Symptoms typically appear after the child turns 5, and they often receive a diagnosis after they turn 10.

3. Hurler-Scheie syndrome (MPS 1H/S) describes an intermediate clinical phenotype — for example when the presentation of the disorder doesn’t fit either the more severe or the milder category.

An alpha-L-iduronidase deficiency causes all these, and distinguishing between them depends on clinical criteria, which include the symptom’s rate of progression.

Mucopolysaccharidosis Type II

Hunter syndrome, or MPS 2, is the only MPS with X-linked inheritance. So, it occurs exclusively in boys, with an incidence rate of 1.3 per 100,000 live male births.

Other Types of MPS

Sanfilippo syndrome, or MPS 3, comes with four subtypes (A through D) differentiated by four separate enzyme deficiencies involved in heparan sulfate degradation. Severe central nervous system disease that leads to progressive neurocognitive deterioration characterizes the condition.

Morquio syndrome, or MPS 4, occurs due to defective degradation of any of the structural carbohydrates in the cartilage, cornea, and bone due to a deficiency in beta-galactosidase, a powerful tool for genetic engineering of bacteria, and an enzyme called N-acetyl-galactosamine-6-sulfatase.

Maroteaux-Lamy syndrome, or MPS 6, is the result of a deficiency in an enzyme called arylsulfatase B, leading to the accumulation of dermatan sulfate, a glycosaminoglycan found mostly in the skin.

Sly syndrome, or MPS 7, results from a beta-glucuronidase deficiency, leading to a lack of dermatan sulfate, heparan sulfate and chondroitin sulfate — a chemical normally present in cartilage around joints in the body.

Hyaluronidase deficiency, or MPS 9, is an extremely rare type of MPS marked by a deficiency in the hyaluronidase enzyme, which is responsible for breaking down hyaluronic acid.

Symptoms of Mucopolysaccharidosis

The symptoms of MPS aren’t present at birth, but begin appearing during childhood. Individuals whose MPS is severe develop this condition’s features earlier than individuals with attenuated MPS.

mps symptoms

The symptoms you experience will depend on the type of MPS you have. For instance, the symptoms and signs of MPS I occur due to the alpha-L-iduronidase enzyme deficiency, required to metabolize or break down complex carbohydrates called mucopolysaccharides.

For instance, some symptoms that could occur in MPS I are:

  • Enlarged vocal cords, leading to a deep voice
  • Enlarged lips, head, tongue, cheeks, and nose
  • An inguinal hernia
  • An umbilical hernia
  • Sleep apnea
  • Frequent upper respiratory infections
  • Enlarged spleen and liver
  • Hydrocephalus
  • Carpal tunnel syndrome
  • Hearing loss
  • Corneal clouding
  • Recurrent ear infections
  • Spinal stenosis, or narrowing of the spinal canal narrowing
  • Joint deformities
  • Short Stature
  • Developmental delays and regression
  • Heart valve abnormalities that could lead to heart failure
  • Generalized thickening of many long bones, especially the ribs

Associated symptoms and signs and the condition’s severity vary substantially by type. Generally, most people with MPS seem healthy at birth, experiencing a period of regular development, but then start declining in mental or physical function. As MPS progresses, it could affect:

  • Organ and system functioning
  • Physical abilities
  • Cognitive development
  • Appearance

Causes of Mucopolysaccharidosis

MPS’ underlying genetic cause will vary depending on its form. Many cases of MPS are genetic, and not associated with the sex chromosomes. However, one specific type of MPS — MPS II — follows an inheritance X-linked pattern.

IDUA gene mutations cause MPS I. The IDUA gene gives instructions for an enzyme production that’s involved in breaking down large sugar molecules called glycosaminoglycans, or GAGs. GAGs used to be called mucopolysaccharides, which is how the condition received its name. IDUA gene mutations reduce or eliminate the IDUA enzyme function.

GAGs accumulate within cells due to the lack of IDUA enzyme activity, particularly inside the lysosomes. These are compartments in the cell responsible for digesting and recycling various types of molecules. Disorders that cause the buildup of molecules inside the lysosomes, MPS I included, are called lysosomal storage disorders.

The accumulation of GAGs enhances the size of the lysosomes, which explains why a lot of organs and tissues become enlarged in people who have this condition. Researchers believe the GAGs could also interfere with other proteins’ functions inside the lysosomes, disrupting the molecule movement inside the cell.

The condition is genetically transmitted, with both parents contributing one recessive gene that carries precisely the same genetic inheritance type. Human traits which include the classic genetic disorders are the product of the two genes interacting for that condition.

Physical Effects of Mucopolysaccharidosis

MPS can cause wide-ranging complications, including:

  • Central nervous system disease
  • Cardiovascular disease
  • Pulmonary disease
  • Ophthalmologic disease
  • Hearing impairment
  • Musculoskeletal disease

Mental Effects of Mucopolysaccharidosis

Individuals with MPS might experience:

  • Increased emotional and physical dependence on their family and friends
  • Low self-esteem
  • Lowered participation in work, school, and social life
  • Mental health and behavioral conditions like depression and anxiety

Impaired cardiopulmonary function among MPS sufferers can cause fatigue, which can produce:

  • Frustration
  • Anger
  • Stress
  • Depression

Mucopolysaccharidosis Statistics

Facts about mucopolysaccharidosis, according to the National Organization for Rare Disorders, include:

  • MPS I affects males and females equally, with an approximate incidence of one in 100,000 live births.
  • Doctors often diagnose MPS I in babies between 6 and 24 months old.
  • Hurler syndrome, or MPS IH/S, first becomes noticeable between 6 months to 2 years old with developmental delay.
  • Scheie syndrome symptoms’ onset in individuals typically occurs after they turn 5 years old. However, diagnosis often gets delayed until they reach between 10 and 20 years old.

Current Treatments Available for Mucopolysaccharidosis and Their Side Effects

Treatment for MPS requires a multidisciplinary team of healthcare professionals because of its wide range of symptoms. This team of doctors could include:

  • Primary care
  • Pulmonology
  • Cardiology
  • Neurology
  • Gastroenterology
  • Ear, nose and throat specialists
  • Orthopedics
  • Audiology
  • Dental
  • Physical therapy
  • Orthopedics
  • Developmental specialists

The two main MPS I treatment options are enzyme replacement therapy and hematopoietic stem cell transplant (HSCT). Both of these help replace the missing IDUA enzyme.

Doctors usually prescribe HSCT to patients with severe MPS I. However, the timing of the treatment will determine its success. Many medical professionals recommend providing HSCT early on, before the patient’s second birthday. Research has shown when HSCT is successful, it can improve auditory, facial and cardiac manifestations.

While the treatment has also been successful in slowing down cognitive decline, its effect on intellectual development isn’t as clear, although some research does suggest an improvement.

A medication called aldurazyme or laronidase is the enzyme replacement therapy for the condition. Laronidase treatment helps improve problems associated with:

  • Growth
  • Breathing
  • Heart
  • Bones
  • Joints

However, this treatment will not help improve issues with mental development, since the drug can’t cross the brain-blood barrier.

Side effects of these medicines may include:

  • A cough
  • Cold symptoms — such as a sore throat, stuffy or runny nose, and sneezing
  • Tingling or numbness
  • Mild skin rash
  • Injection site reactions, including redness, swelling, pain or other irritation
  • Overactive reflexes

Recent Developments in Mucopolysaccharidosis

New insights on the pathophysiology of mucopolysaccharidosis disorders are leading to gene therapy, alternative therapeutic approaches, substrate reduction therapy, and inflammatory response modulators.

Researchers are conducting a study to evaluate the side effects and efficacy of donor hematopoietic cells through the use of a chemotherapy regimen and not total-body irradiation in kids with MPS undergoing a hematopoietic stem cell transplant.

Scientists are also carrying out a study to evaluate the safety and efficacy of the drug JR-141 for MPS II.

How and Why Marijuana Can Be an Effective Treatment for Mucopolysaccharidosis

Patients with MPS might experience considerable discomfort and pain alongside the condition. Traditionally, doctors have treated pain with opioid narcotics like Percocet and Vicodin, as well as analgesics like acetaminophen or ibuprofen.

While opioids are effective in relieving chronic pain, they come with side effects and highly addictive properties. Analgesics, while not addictive, aren’t that effective in eliminating pain, and can have serious side effects from long-term use like liver damage, stomach bleeding and kidney damage.

Medical marijuana and mucopolysaccharidosis treatment is much safer than opioids. In many cases, medical weed has not only reduced the side effects of opioids and other medicines but has also helped improve patients’ quality of life. Be aware, however, cannabis can come with some side effects like:

  • Red eyes
  • Dry eyes
  • Dry mouth
  • Short-term memory loss
  • Constipation
  • Fatigue
  • Hunger

Many years’ worth of anecdotal evidence shows marijuana’s efficacy in treating chronic pain conditions. These days, scientific and medical communities are catching up with what cannabis advocates have known for some time now.

A review of 28 studies evaluating cannabinoids for treating pain and other medical issues has the support of quality evidence.

Some of the symptoms of MPS cause nausea in patients. Severe nausea keeps cells from fulfilling their essential functions, including:

  • Proper digestion
  • Appetite responses
  • Basic functionality

Endocannabinoids, the endocannabinoid system’s backbone, consist of a variety of enzymatic pathways forming patterns in the brain. These inform the brain of various functional roles. In individuals with severe nausea, these pathways become disturbed. For a lot of patients, however, CBD products can help get the body back on track.

What Side Effects and Symptoms of Mucopolysaccharidosis Can Medical Marijuana Treat?

Pain is often common in mucopolysaccharidosis patients. As mentioned above, medical weed has been proven to help reduce or eliminate pain, helping improve the patient’s quality of life.

Depression and anxiety are also often a problem for many MPS patients. Several strains of medical pot are ideal for helping people restore their mental health.

The symptom of hydrocephalus in MPS can cause nausea and vomiting, headaches, irritability, and sleepiness, all of which medical marijuana for mucopolysaccharidosis can help treat.

Nausea and vomiting is also a symptom of the hepatosplenomegaly symptom in MPS.

Recurrent ear infections are another symptom of MPS and can cause pain, inflammation, nausea, vomiting, and headache. Cannabis can be helpful for all these symptoms.

Spinal stenosis, another MPS symptom, causes pain, cramping, muscle weakness and a pins-and-needles sensation in the legs, back, and buttocks. Medical weed can often alleviate these symptoms.

Best Strains of Marijuana to Use for Symptoms of Mucopolysaccharidosis

Medical cannabis for mucopolysaccharidosis offers the benefit of being a consistent, professionally cultivated product. Commercial growers can produce plants more accurately with the proper balance of cannabinoid compounds to help with specific conditions and symptoms.

Since mucopolysaccharidosis’ symptoms are so diverse, including problems such as hydrocephalus, sleep apnea, and an enlarged liver and spleen, you’ll need to research your strains thoroughly.
