What Are the 5 Types of Psoriatic Arthritis? 

Psoriatic arthritis affects people in different ways. Among these are joint pain and stiffness, and swollen tendons. This can affect tendons attached to bones, such as the Achilles tendon, plantar fascia, and pelvic bones. Enthesitis affects the Achilles tendon and plantar fascia, and tenosynovitis affects the sheaths that surround these tendons.

Distal interphalangeal predominant 

Distal interphalangeal predominant SAR is a less common form of psoriatic arthritis, accounting for less than 10 percent of all psoriatic arthritis cases. Treatment for this form of the disease usually involves soaking the hands in warm water, maintaining cuticles, and taking regular pain medications. In more severe cases, DMARDs and corticosteroid injections may be required. 

The symptoms of Distal interphalangeal predominant SAR are similar to those of other psoriatic arthritis types. They can include generalized aches and pain, as well as swelling and inflammation of small joints. Patients may also experience nail changes, including small depressions in the nails. Sometimes the disease can also affect the eyes and cause skin problems. 

Asymmetric oligoarticular 

Asymmetric oligoarticular p, or asymmetric OA, is a form of psoriatic arthritis that affects different joints on both sides of the body. Around 35 percent of the population suffers from this condition. People who have this disease often have similar symptoms to rheumatoid arthritis. Symptoms can include nail changes and pain. 

Unlike symmetric oligoarticular PsA, asymmetric oligoarticular PsA affects fewer joints on one side of the body than the other. This type of PsA typically starts in a single joint, such as the knee. As a result, some doctors may have trouble diagnosing a patient with this type of psoriatic arthritis. 

Symmetric polyarthritis 

People with psoriatic arthritis can experience pain and stiffness in the joints. About half of psoriatic arthritis patients experience morning stiffness. They can also experience skin patches covered with silvery-white scales, often with raised edges. Some patients will have pitted nails as well. In addition, about one in five people with the condition will experience symmetric polyarthritis, which affects at least five joints on both sides of the body. Like rheumatoid arthritis, symmetric polyarthritis causes pain, swelling, and inflammation in the joints and other parts of the body. 

The pathogenesis of psoriatic arthritis is complicated by several factors. While the exact cause of psoriatic arthritis is unknown, it has been shown that inflammation in the joints and skin is associated with elevated production of tumor necrosis factor (TNF-alpha). The release of proinflammatory cytokines, such as TNF-alpha, is thought to be a factor in inflammation. In addition to contributing to inflammation, TNF-alpha has been linked to cardiovascular and metabolic effects. 


Spondylitis is an inflammatory form of psoriatic arthritis that affects the spinal column. It causes pain and stiffness in the neck, lower back, and sacroiliac joints. In some cases, it can lead to spine fusion. 

If you are experiencing pain in any of these areas, consult a doctor. The treatment for psoriatic spondylitis differs from that for other forms of psoriatic arthritis. Patients with psoriasis should undergo a physical examination to rule out other causes of pain in their spine. Imaging tests may be required.
