Most of the differential diagnosis factors with gout can be considered here. Infection is always a major differential, especially in the patient presenting with new acute monoarticular arthritis. In addition, septic arthritis can coexist in a joint that has been or is involved in an acute CPPD disease attack as with gout. Thus, it is important to aspirate the involved joint whenever possible for microscopic examination of the synovial fluid and Gram stain and culture.

Many people have no symptoms and are not aware they have CPPD. This form of CPPD causes an immune response that results in sudden, severe pain, swelling, redness, warmth, as well as other possible symptoms. Doctors sometimes refer to pseudogout and gout as crystal-induced arthropathies, which simply means they are joint diseases caused by microscopic crystals. You may need several tests to find out what’s causing your joint pain. If you have any type of joint pain, your doctor will likely send you for an X-ray.

This is the average effective dosage necessary for patients with normal renal function. Frequently, allopurinol therapy is initiated at a dosage of 100 mg per day and increased in increments of 50 to 100 mg per day every two weeks until the patient's urate level is less than 6 mg per dL (355 μmol per L). Unless the serum urate level is lower than 6.4 mg per dL (380 μmol per L), the concentration at which urate saturates the extra-cellular fluid, crystals will not be absorbed, and tophi will continue to form.

It is a condition that affects not only the joints but also the tissues that surround the joints and the connecting tissues around the affected area.

What Are The Drugs Used For Gout?

Pseudogout results from the abnormal formation of calcium pyrophosphate crystals in the cartilage , which is later followed by the release of crystals into the joint fluid. When CPP crystals are released into the joint, they can cause a sudden attack of arthritis, similar to gout. Pseudogout has been linked to the presence of calcium pyrophosphate dihydrate crystals within the affected joint. These crystals become more numerous as people age, appearing in nearly half the population older than age 85. But most people who have these crystal deposits never develop pseudogout.

Changes in urate levels can result from acute alcohol ingestion, acute overindulgence in foods high in purines, rapid weight loss, dehydration, or trauma. The heritability of serum urate levels is estimated at 63%. Genome-wide association studies have identified several candidate loci associated with chronically elevated serum urate concentrations and gout. Foods that are rich in purines include anchovies, sardines, sweetbreads, kidney, liver, and meat extracts.

What is the difference between gout and pseudogout?

While gout is caused by uric acid crystals; pseudogout is caused by calcium pyrophosphate dehydrate crystals (CPPD). And though the two have similar symptoms, treatment is somewhat different. Pseudogout causes sudden attacks of joint pain, swelling, and warmth. The attacks can last for days to weeks.

Here’s what you should know about the difference between gout and pseudogout. It’s very difficult to tell the difference between gout and pseudogout. In fact, pseudogout got its name, which means “false gout,” because it’s so hard to distinguish between the conditions. Gout is caused when uric acid leads to crystal buildup in the joint.

Although genetic factors have been strongly associated with hyperuricemia, environmental and other state-of-health factors are responsible for the majority of the gout burden in developed countries. About 90% of patients with gout develop excess urate stores because of an inability to excrete sufficient amounts of uric acid in the urine . Most of the remaining patients either overconsume purines or produce excessive amounts of uric acid endogenously . A few have impaired intestinal elimination of uric acid. A gout attack may be triggered either by release of crystals or by precipitation of crystals in a supersaturated microenvironment .

For example, basic calcium phosphate crystals cause acute calcific tendinitis and the Milwaukee shoulder syndrome. More significantly, calcium pyrophosphate crystals are related to a variety of articular manifestations known as calcium pyrophosphate deposition arthritis. CPPD arthritis is very common and its incidence increases with age. Gout is a picturesque presentation of uric acid disturbance. It is the most well understood and described type of arthritis. New insights into the pathophysiology of hyperuricemia and gouty arthritis; acute and chronic allow for an even better understanding of the disease.

All individuals with gout have hyperuricemia; however, hyperuricemia is also found in patients taking diuretics and even in those taking niacin or low doses of aspirin. If your joint has a significant buildup of calcium pyrophosphate crystals that are causing severe pain, your doctor might recommend joint-replacement surgery. Another common trigger of gout attacks is stress to the body and dehydration.

However, the type of crystals and what causes them differ between the conditions. While that can be said of any disease or condition, it is especially true when there are overlapping symptoms or when one condition mimics another. See your doctor if you experience a suddenly painful joint. Whereas gout is often exacerbated by consuming meat, seafood, and alcohol, diet does not affect the onset or development of pseudogout or control symptoms. Though the crystals associated with pseudogout are partly calcium, it is a myth that consuming foods high in calcium provokes the development of pseudogout.
