-
-
- Pseudogout is a disorder resembling gout, characterized by deposits of calcium
- pyrophosphate dihydrate crystals in a single joint or multiple joints which
- causes mild chronic inflammation of those joints.
-
- Symptoms
-
- Pseudogout can appear in a chronic or acute form, or a combination of these
- two types.
-
- About one-fourth of patients with Pseudogout experience one or more acute
- (sudden) attacks characterized by rapid swelling and pain in a joint,
- stiffness and occasional redness and heat over the affected area. An attack
- usually reaches its peak within 12 to 36 hours and can last several days to
- weeks. In most people the symptoms of acute attacks will disappear
- eventually even without treatment. The most commonly affected joint is the
- knee, although any joint may be affected.
-
- The milder non-acute forms of the disorder are more likely to occur in
- several joints such as the wrists and fingers, as well as the knee. Pain and
- swelling occur, not as severe as in a sudden attack, but they tend to last
- longer. People with chronic Pseudogout find that pain becomes worse with
- activity. Some experience acute attacks as well as the chronic form, while
- others with the chronic form may never experience an acute attack.
-
- Causes
-
- The cause of Pseudogout is unknown. Its frequent association with other
- conditions such as osteoarthritis, diabetes mellitus, hyperparathyroidism,
- gout or hemochromatosis suggests that the deposits of the CPPD crystals in
- the cartilage are secondary to degenerative changes in the joints. A
- familial pattern of incidence has been observed in several countries.
-
- Affected Population
-
- Pseudogout appears in mature adults. Both sexes are affected equally. The
- incidence of asymptomatic calcinosis of cartilage in joints in persons over
- age 50 is appreciable.
-
- Related Disorders
-
- Gout is a recurrent acute arthritis of peripheral joints which results from
- deposition, in and about the joints and tendons, of monosodium urate crystals
- from supersaturated hyperuricemic body fluids. This disorder may become
- chronic and deforming, but in most cases it is responsive to drugs and diet
- therapy.
-
- Therapies: Standard
-
- Acute attacks of Pseudogout are treated by removing the excess fluid and CPPD
- crystals from the affected joint. The drugs used most often for treatment of
- Pseudogout are aspirin and the other non-steroidal anti-inflammatory drugs
- such as those commonly prescribed for many types of arthritis. These drugs
- reduce the pain and swelling caused by inflammation. Stomach upset is a
- common side effect of these drugs which may be avoided if they are taken with
- milk or food.
-
- If an acute attack has occurred in only one joint, a corticosteroid may
- be injected into the joint.
-
- During an attack of Pseudogout the affected joint may need rest.
- Splints, canes and other devices for protecting joints may be fitted. Once
- the episode subsides, or in cases of the milder chronic form, rest should be
- balanced with appropriate exercise prescribed by a doctor or a physical
- therapist.
-
- In a very few people with Pseudogout, surgery may be necessary to correct
- a joint that is badly damaged, very painful or unstable. Surgery can be
- performed either to repair a joint or to replace it entirely with an
- artificial joint. Surgery can be effective for reducing pain, improving
- movement and correcting disability.
-
- Therapies: Investigational
-
- Researchers at the Mayo Clinic in Rochester, MN have tested the experimental
- anti-inflammatory drug colchicine as a treatment in severe cases of
- Pseudogout when symptoms did not respond to any other treatment. More
- research is needed before this drug can be recommended for treatment of
- Pseudogout.
