What is Pseudogout?
Pseudogout is a type of arthritis that is characterized by the development of a painful swelling that occurs suddenly in one or more joints. It is also known as calcium pyrophosphate deposition disease (CPPD) because of the type of crystals that are deposited on the joint during the disease process.
Which are the Joints Commonly Affected by Pseudogout?
The most commonly affected joints are the knees, followed by the wrists and ankles.
What are the Symptoms of Pseudogout?
During a pseudogout attack, the following signs and symptoms may be experienced in the affected joints:
- Swelling
- Warmth
- Severe pain
What are the Causes of Pseudogout?
Pseudogout has been associated with the deposition of pyrophosphate dihydrate crystals inside the joint, although most people with such crystal deposits do not develop pseudogout. These crystals increase in number as you grow older and are present in at least half of the population over the age of 85 years.
What are the Risk Factors for Pseudogout?
The following factors put you at a higher risk of developing pseudogout:
- Old age: Your risk for developing pseudogout increases as you grow older.
- Traumatic joint injury: Having sustained serious joint trauma or undergoing surgery increases your risk.
- Genetic predisposition: You may be at a higher risk for pseudogout if other members of your family have the condition.
- Mineral imbalance: High blood levels of calcium and iron, and low levels of magnesium increase your risk for pseudogout.
- Certain medical conditions: Pseudogout has been linked with the presence of an underactive thyroid gland or an overactive parathyroid gland.
What are the Complications of Pseudogout?
The pyrophosphate dihydrate crystals which have been linked to pseudogout may damage the joint, mimicking signs and symptoms of rheumatoid arthritis or osteoarthritis.
