Pseudogout is a common crystal-induced arthropathy caused by calcium pyrophosphate (CPP) crystals.
Presentation
The following are the signs and symptoms of pseudogout:
Entire Body System
-
Fever
The patient exhibited severe neck pains, headache, high fever and a pain in his knee joints together with symptoms of the central nervous system. The patient's cerebrospinal fluid was almost clear and showed no sign of viral infection. [ncbi.nlm.nih.gov]
Medicines NSAIDs, such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. [drugs.com]
Postoperative Course Approximately 5 weeks after surgery, the patient presented to the emergency department with 2 days of midback spasms, fever, and chills. Her temperature was 102 F, and blood inflammatory markers were elevated. [thejns.org]

Joint Swelling
Pseudogout or calcium pyrophosphate deposition disease (CPDD) is a form of inflammatory arthritis caused by crystals forming in the joints. [hss.edu]
This leads to attacks of joint swelling and pain in the knees, wrists, ankles, and other joints. Among older adults, CPPD is a common cause of sudden (acute) arthritis in one joint. [mountsinai.org]
These crystals irritate the joints, and cause the body to release chemicals that make the joints swell. This results in the irritated area of the hand to become painful and appear red. [arorahandsurgery.com]
Joint swelling occurs, as well as local heat and thickening of the lining of the joint – the synovium. Accumulation of fluid is called an effusion. Course The prognosis is usually good, but severe joint damage can occur. [health24.com]

Workup
Signs and symptoms of pseudogout are similar to those of gout. Therefore, it is necessary to carry out various tests to arrive at a definitive conclusion. The following methods are employed to diagnose pseudogout:
- Laboratory tests to detect the presence of crystals in the joints are done. In this, fluid is retrieved from the joints and is tested for the presence of crystals. In addition, blood tests may also be carried out to determine other underlying conditions such as thyroid disorders or mineral imbalances that can give rise to pseudogout.
- Imaging studies such as X-ray of the affected joint is done to determine the extent of damage to the joint. An X-ray examination of the joint would also reveal deposition of crystals.
Treatment
Pseudogout cannot be cured, however various treatment methods can help in effective management of the condition. Treatment regime is geared towards relieving the symptoms and discomfort experienced due to the arthritic attack. The following methods are employed for management of pseudogout:
- Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids and colchicines are administered for relieving the inflammation and the associated pain in the affected joint. Individuals who are prone to suffer from recurrent attacks of pseudogout are advised to take colchicines as prophylactic measure.
- There is accumulation of fluid in the affected joint that leads to pain and inflammation. This fluid is drained with the help of a needle or scalpel (surgical decompression) which is inserted into the affected area to aid in fluid removal [10]. Such a kind of process also helps in removing significant amount of crystals from the joints.
Prognosis
Prognosis of the condition is usually favorable with timely initiation of treatment. Affected individuals are reported to do well with medications and other therapies. Acute attacks are known to resolve within 10 days of receiving treatment.
Complications
Complications occur when the individuals do not seek proper medical treatment. In such cases, the joint undergoes constant and permanent damage by the deposited crystals.
Etiology
The deposition of calcium pyrophosphate crystals in the joints gives rise to development of pseudogout. What triggers the deposition of calcium salts is not known, but advancing age is thought to be the major factor. More than 50% of individuals aged 85 years and above have deposits of calcium salts in their joints. However, not all of them develop pseudogout. The reason behind this is still not understood. Genetic transmission has also been implicated in the expression of pseudogout [2].
Some of the risk factors contributing to development of deposition of calcium pyrophosphate crystals include the following:
- Hemochromatosis
- Hypomagnesemia
- Hyperparathyroidism
- Hypercalcemia
- Hypothyroidism
- Acromegaly
- Wilson disease
- Intake of loop diuretics [3]
- Etidronate sodium therapy for osteoporosis [4]
- Dyes from diagnostic angiography [5]
- Spinal surgery [6]
Epidemiology
Pseudogout is a common occurrence affecting about 1.3 per 1000 adult individuals. Incidence of pseudogout varies with age and older aged individuals, especially women, are known to be more affected by this condition.
It has also been estimated that about 30% of individuals above the age of 60 years and 50% individuals above 90 years were found to have deposits of calcium crystals in their joints. In addition, there is a considerable amount of risk associated with onset of pseudogout and development of heart diseases in the affected individuals.
Pathophysiology
Deposition of calcium pyrophosphate (CPP) crystals in the joints of individuals gives rise to pseudogout [7]. The exact factor that triggers such a kind of event is yet to be figured out. The deposition of the calcium pyrophosphate crystals in the joints causes the area to swell and be painful. The affected area also feels warm when touched.
The knee is the most common joint for development of pseudogout; however other areas such as ankle and wrist can also be affected. There are crystal arthropathies that involve both pseudogout and gout at the same time [8].
Prevention
Pseudogout cannot be prevented. However, the various conditions that can give rise to development of such a condition should be treated to avoid the onset of pseudogout.
Summary
Pseudogout also known as calcium pyrophosphate deposition disease is caused due to deposition of calcium pyrophosphate crystals in the joints [1]. It is a type of arthritis significantly affecting the knee and other joints. Pseudogout is a serious condition causing pain and inflammation and the attacks can last for several days to weeks, severely affecting the patients life.
Pseudogout needs appropriate diagnosis and prompt treatment to avoid worsening of the condition. Women fall easy prey to this arthritic condition as compared to males. Pseudogout received its identity in the year 1962 when the condition was described to have independent characteristic features from gout.
Patient Information
Definition
Pseudogout is a type of arthritis that severely affects the joints causing inflammation and pain. In this condition, crystals of calcium pyrophosphate get deposited in the joint. Females are more prone to contract this condition than males.
Cause
Age is known to be the most common factor for pseudogout. As individual ages, the crystals get deposited into the joints giving rise to arthritic pain. Certain underlying conditions are also known to give rise to pseudogout. These are thyroid disorders, parathyroid diseases, Wilson disease, acromegaly and hemochromatosis.
Symptoms
Symptoms of pseudogout precipitate as pain and inflammation in the affected joints. The affected area is also warm to touch. An attack of pseudogout lasts for several days and should usually resolve with prompt initiation of treatment.
Diagnosis
Diagnosis of pseudogout is carried out by an X-ray examination of the joints that reveal the presence of crystals and damage to the area. In addition, laboratory tests are also conducted to determine the presence of any underlying disease conditions. In many cases, the fluid from the joint is also tested for the presence of crystals.
Treatment
Pseudogout cannot be cured. With appropriate medications and therapies the condition can be effectively managed and symptoms kept under control. Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids are employed for relieving the pain and inflammation in the joint. Individuals prone to frequent attacks are given colchicines as a preventive regime. Fluid that gets accumulated in the joints can also be removed to reduce the associated pain and inflammation.
