Sanfilippo Syndrome – Symptoms, Diagnosis, and Supportive Care

What is Sanfilippo Syndrome?

Sanfilippo Syndrome (also known as Mucopolysaccharidosis Type III - MPS III) is a rare, inherited metabolic disorder caused by a deficiency in one of four enzymes responsible for breaking down heparan sulfate, a complex sugar molecule. The deficiency leads to the accumulation of heparan sulfate in the body, particularly in the brain, which causes progressive neurological damage. Sanfilippo Syndrome is classified into four subtypes: MPS IIIA, MPS IIIB, MPS IIIC, and MPS IIID, depending on which enzyme is deficient.

Symptoms of Sanfilippo Syndrome

Sanfilippo Syndrome generally manifests in early childhood, often between the ages of 2 and 6 years. Common symptoms include:

• Developmental delay: Delays in speech, motor skills, and cognitive development.

• Neurological issues: Behavioral problems, hyperactivity, seizures, and sleep disturbances.

• Physical features: Coarse facial features and a larger head size.

• Movement disorders: Difficulty with coordination, loss of motor skills, and walking problems.

• Hearing loss: Progressive hearing impairment.

• Vision issues: Corneal clouding, leading to vision difficulties.

• Cardiac issues: Enlarged heart and possible valve abnormalities.

• Behavioral problems: Aggression, self-injurious behavior, and anxiety.

• Gastrointestinal problems: Difficulty swallowing, constipation, and feeding difficulties.

Diagnosis of Sanfilippo Syndrome

Sanfilippo Syndrome is diagnosed through a combination of clinical observation and laboratory tests. Key diagnostic steps include:

• Enzyme activity testing: Measuring enzyme activity in blood, skin, or urine samples to detect deficiencies in one of the four enzymes involved in breaking down heparan sulfate.

• Urinary glycosaminoglycan (GAG) testing: Elevated levels of GAGs are indicative of MPS III.

• Genetic testing: DNA testing can identify mutations in the genes that encode the enzymes deficient in Sanfilippo Syndrome.

• Imaging: MRI scans can detect brain abnormalities due to the buildup of heparan sulfate.

Early diagnosis allows for better management of the condition and may help in planning treatments and interventions to improve quality of life.

Treatment Options for Sanfilippo Syndrome

Currently, there is no cure for Sanfilippo Syndrome, but various treatments can help manage symptoms and improve quality of life. The treatment focus is on alleviating symptoms and slowing disease progression:

• Symptomatic treatment: Treatment to manage seizures, sleep disturbances, gastrointestinal issues, and behavior problems.

• Enzyme replacement therapy (ERT): Some subtypes of Sanfilippo Syndrome may benefit from enzyme replacement therapy, though its effectiveness in treating neurological symptoms is still under investigation.

• Stem cell therapy: Research into stem cell-based treatments is ongoing, and some studies show promise for treating the neurological aspects of the disorder.

• Physical, occupational, and speech therapy: These therapies help with mobility, communication, and daily functioning. Physical and occupational therapy can support children with motor difficulties, while speech therapy aids with communication and swallowing issues.

• Seizure management: Anti-seizure medications may be prescribed to manage the neurological symptoms.

• Behavioral therapy: Behavioral interventions can assist in managing aggression, anxiety, and other behavioral issues.
