- Pseudogout is caused by crystals in a joint.
- Pseudogout causes arthritis (joint inflammation).
- Pseudogout can cause calcification of cartilage.
- The arthritis of pseudogout is diagnosed by detecting typical crystals in joint fluid.
- Treatment of pseudogout is directed at the inflammation.
- Pseudogout can be associated with other illnesses.
What is pseudogout?
Pseudogout is a type of inflammation of joints (arthritis) that is caused by deposits of crystals, called calcium pyrophosphate, in and around the joints. Pseudogout literally means "false gout." It derives its name from its similarity to gout.
Pseudogout has many similarities to true gout, which also can cause arthritis. However, the crystal that incites the inflammation of gout is monosodium urate. The crystals that cause pseudogout and gout each have distinct appearances when joint fluid containing them is viewed under a microscope. This makes it possible to precisely identify the cause of the joint inflammation when joint fluid is available.
Pseudogout has been reported to occasionally coexist with gout. This means that the two types crystals can sometimes be found in the same joint fluid. Researchers have also noted that the cartilage of patients who had both forms of crystals in their joint fluid was often visibly calcified, as seen on X-ray images.
What are causes of pseudogout?
Pseudogout is primarily caused by the precipitation of calcium pyrophosphate dihydrate crystals developing within a joint space. Pseudogout has sometimes been referred to as calcium pyrophosphate deposition disease or CPPD.
Pseudogout is clearly related to aging as it is more common in the elderly and is associated with degenerative arthritis. Acute attacks of the arthritis of pseudogout can be caused by dehydration. This is particularly common in hospitalized patients and those recovering from operations, especially when associated with dehydration. Pseudogout can also be caused by the hormonal effects on calcium metabolism from hyperparathyroidism.
