What is Psoriatic Arthritis?

Psoriatic arthritis (PsA) is a form of inflammatory arthritis that affects some people with psoriasis, a chronic skin condition characterized by red patches and silvery scales on the skin [1]. It is a progressive condition that causes joint pain, swelling, and stiffness, as well as inflammation in the connective tissue, known as entheses [6].

Symptoms of Psoriatic Arthritis

The symptoms of psoriatic arthritis can vary from person to person but often include:

• Joint pain and stiffness
• Swelling along the bones that form the joints
• Inflammation in the connective tissue (entheses)
• Pain and swelling in any joint in the body [9]

Causes and Risk Factors

Psoriatic arthritis is an autoimmune condition, meaning that the immune system mistakenly attacks healthy tissues. It can occur with or without psoriasis, but people with a history of psoriasis are at higher risk of developing PsA [7].

Treatment Options

While there is no cure for psoriatic arthritis, various treatments can help manage symptoms and slow disease progression. These include medications to reduce inflammation and relieve pain, as well as lifestyle changes such as maintaining a healthy weight and exercising regularly [5].

Common Signs and Symptoms of Psoriatic Arthritis

Psoriatic arthritis (PsA) is a long-term condition that causes joint pain, swelling, and stiffness in people who have psoriasis. The symptoms can vary from person to person, but here are some common signs and symptoms:

• Joint Pain and Stiffness: Joint pain and stiffness are the most common symptoms of PsA. They can affect any part of the body, including your fingertips, hands, feet, wrists, knees, and ankles [1].
• Skin Rashes and Changes: People with PsA often experience skin rashes and changes in their fingernails and toenails [2].
• Fatigue: Fatigue is a common symptom of PsA, which can make it difficult to perform daily activities [3].
• Swollen Joints: One of the first signs of PsA is often a swollen joint, most commonly in a hand, foot, or knee [4].
• Deformed Joints: Chronic inflammation can cause deformed joints, especially in the fingers and toes [5].

Other Symptoms

In addition to these common symptoms, people with PsA may also experience:

• Pain and tenderness in different parts of the body (e.g., right hand and left knee) [6]
• Early morning stiffness that lasts for more than 30 minutes
• Swelling and redness around the affected joints
• Limited range of motion in the affected joints

Diagnostic Tests for Psoriatic Arthritis

Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects the joints and skin, but there is no definitive diagnostic test to confirm its presence. However, various tests can help healthcare providers diagnose PsA by ruling out other causes of joint pain.

• Physical Examination: A thorough examination by a physician can reveal swollen or tender joints, which are common symptoms of PsA [1].
• Blood Tests: Blood tests can help rule out other conditions that cause similar symptoms. For example, rheumatoid factor and anti-citrullinated protein antibody (anti-CCP) tests can help differentiate PsA from rheumatoid arthritis [2]. Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP) tests can also be used to monitor inflammation levels [3].
• Imaging Tests: Imaging tests such as X-rays, ultrasounds, or magnetic resonance imaging (MRI) can reveal changes in joints, entheses, or the spine, which are characteristic of PsA [4]. These tests can help identify joint damage and rule out other conditions.

Common Diagnostic Tests for Psoriatic Arthritis

• Ultrasound imaging test
• X-ray imaging test
• CT imaging test
• MRI imaging test
• Skin or nail examination

It's essential to note that no single test can confirm a diagnosis of psoriatic arthritis. A combination of clinical evaluation, laboratory tests, and imaging studies is often used to diagnose PsA [5].

Treatment Options for Psoriatic Arthritis

Psoriatic arthritis (PsA) can be effectively managed with various treatment options, including medications and lifestyle changes. Here are some common drug treatments used to manage the symptoms of PsA:

• Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): These over-the-counter medications, such as ibuprofen or naproxen, can help relieve pain and reduce inflammation in the joints [2].
• Corticosteroids: These powerful anti-inflammatory medications can be injected directly into affected joints to provide quick relief from symptoms [6].
• Immunosuppressants: Medications like azathioprine and cyclosporine can help ease joint pain and swelling by suppressing the immune system's attack on healthy tissues [7].
• Methotrexate: This immunosuppressive drug is often used to treat psoriasis, but it also works well for PsA and can help prevent joint damage [8].

Commonly Prescribed Medications

Some commonly prescribed medications for PsA include:

• Adalimumab (Humira)
• Etanercept (Enbrel)
• Infliximab (Remicade)
• Golimumab (Simponi)

These medications are typically used in combination with other treatments, such as NSAIDs or corticosteroids, to manage the symptoms of PsA [1].

Other Treatment Options

In addition to medication, other treatment options for PsA may include:

• Physical therapy
• Occupational therapy
• Lifestyle changes, such as maintaining a healthy weight and exercising regularly

It's essential to work with a healthcare provider to determine the best course of treatment for individual cases of PsA.

Differential Diagnosis of Psoriatic Arthritis

Psoriatic arthritis (PsA) can be challenging to diagnose due to its shared symptoms with other types of arthritis. A differential diagnosis approach is necessary to rule out other conditions and confirm the presence of PsA.

Key Features for Differential Diagnosis

• Enthesitis: Inflammation of the tendons and ligaments, which can aid in the differential diagnosis of PsA [3].
• Dactylitis: Swelling of an entire toe or finger, which is a fairly specific sign of PsA that can help with differential diagnosis, especially when accompanied by enthesitis [9].
• Uveitis and Iritis: Inflammatory eye diseases that are associated with PsA [4].

Common Misdiagnoses

Prior to receiving a diagnosis of PsA, patients often experience misdiagnosis. The most common misdiagnoses include:

• Psychosomatic disorder: A condition where physical symptoms are caused by psychological factors (26.6%) [6].
• Osteoarthritis: Wear and tear on the joints, which can be mistaken for PsA (21.7%) [6].
• Anxiety or depression: Mental health conditions that can present with similar symptoms to PsA (18.2%) [6].

Differential Diagnosis Subsets

The differential diagnosis of PsA involves distinguishing it from other inflammatory arthropathies, such as rheumatoid arthritis (RA). The subsets of PsA include:

• Axial PsA: Involves the spine and sacroiliac joints.
• Symmetrical polyarthritis: Characterized by symmetrical joint involvement.
• Nail lesions: Pitting or onycholysis (separation of the nail from the nail bed).
• Pitting edema: Swelling of the feet and ankles due to fluid retention.
