Creutzfeldt-Jakob Disease Case: Woman Dies After 50-Year Latency

Background

Creutzfeldt-Jakob disease (CJD) is a rare and fatal prion disease that causes rapid neurodegeneration. Prions are infectious misfolded proteins that trigger normal proteins in the brain to misfold and clump together, disrupting brain function. Iatrogenic CJD (iCJD) is a form of the disease transmitted through medical procedures, such as the use of contaminated surgical instruments or, as in this case, human growth hormone derived from cadavers.

The Case

The woman in this case received cadaveric human growth hormone (chGH) for nearly 10 years, starting at age 7. She presented with gait imbalance and tremors almost five decades later. After the onset of symptoms, her condition rapidly deteriorated, leading to coma and death. An autopsy confirmed iCJD, with the source likely being the contaminated chGH she received as a child.

Diagnosis of CJD

Diagnosing CJD involves several steps:

Why This Matters

This case underscores the importance of recognizing the potential for long latency periods in iCJD and maintaining vigilance in diagnosing unexplained neurological symptoms in individuals with a history of receiving human-derived biological products. It also highlights the significance of stringent screening and purification processes for biological materials used in medical treatments.

CJD is a rare, fatal brain disorder caused by infectious misfolded proteins called prions.

CJD can occur sporadically, be inherited, or be transmitted through contaminated medical equipment or biological products.

Symptoms include cognitive decline, muscle jerks, coordination problems, and vision issues.

Currently, there is no cure for CJD. Treatment focuses on managing symptoms and providing supportive care.
