Summary

Cerebrotendinous xanthomatosis (CTX) can present with joint pain and neurological symptoms. Early diagnosis and treatment with chenodeoxycholic acid (CDCA) are crucial for managing this rare genetic disorder.

Area of Science:

  • Neurology
  • Genetics
  • Biochemistry

Background:

  • Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder.
  • It is characterized by defective bile acid synthesis, leading to accumulation of cholestanol and cholesterol in tissues.
  • CTX typically presents in adulthood with tendon xanthomas, cataracts, and progressive neurological dysfunction.

Observation:

  • A patient presented to a Rheumatologist with lower limb joint and muscle pain.
  • Clinical findings included bilateral Achilles tendon xanthomas, a parapareto-spastic gait, positive Babinski sign, hyperreflexia, and bilateral cataracts.
  • Elevated plasma cholesterol levels were noted, supporting the diagnosis.

Findings:

  • The patient's presentation was interpreted as CTX with spinal involvement.

  • The underlying biochemical defect involves impaired bile acid synthesis.
  • Chenodeoxycholic acid (CDCA) treatment has shown beneficial effects, particularly in early-stage CTX.

    • Implications:

    • This case highlights the importance of early diagnosis of CTX to prevent disease progression.
    • Recognizing the diverse clinical manifestations, including rheumatologic and neurological signs, is crucial.
    • Advances in therapeutic regimens offer hope for better management and improved outcomes in CTX patients.
