Understanding Psoriatic Arthritis
Psoriatic arthritis (PsA) is a chronic, immune-mediated inflammatory disease associated with psoriasis. While many patients develop psoriasis first, musculoskeletal symptoms may precede skin disease. PsA is a systemic condition that can affect multiple organ systems beyond the joints.
The Arthritis Center of Nebraska specializes in the diagnosis and comprehensive management of psoriatic arthritis, addressing its multidomain involvement through coordinated, specialty-based care.
Multidomain Involvement in Psoriatic Arthritis
Psoriatic arthritis may involve one or more of the following domains:
- Articular (Peripheral joints):
Joint pain, stiffness, and swelling; often asymmetric and may involve the hands, feet, knees, or wrists. - Axial disease:
Inflammatory involvement of the spine and sacroiliac joints, causing chronic back pain and stiffness. - Enthesial involvement (Enthesitis):
Inflammation where tendons or ligaments attach to bone, commonly affecting the heels, plantar fascia, or elbows. - Dactylitis:
Diffuse swelling of entire fingers or toes (“sausage digits”). - Dermatologic disease:
Psoriasis involving the skin and nails, including nail pitting, onycholysis, or crumbling. - Ocular involvement:
Inflammatory eye disease such as uveitis, which may cause eye pain, redness, or vision changes. - Bowel involvement:
Association with inflammatory bowel disease (IBD) in some patients.
Because disease expression varies widely, treatment must be individualized and domain-specific.
Disease Course
Psoriatic arthritis is a chronic condition characterized by flares and remission. Without treatment, persistent inflammation can lead to irreversible joint damage, functional impairment, and reduced quality of life. Early diagnosis and appropriate therapy are essential.
Our Treatment Approach
Management focuses on controlling inflammation across all affected domains, preventing joint damage, and improving overall function.
Treatment may include:
- Disease-modifying antirheumatic drugs (DMARDs)
- Targeted biologic and oral therapies addressing joint, skin, axial, enthesial, ocular, and bowel involvement
- Short-term anti-inflammatory medications for symptom relief
- Ongoing monitoring to guide treatment adjustments and ensure safety
Therapy selection is tailored to the specific domains involved and patient comorbidities.
Coordinated Specialty Care
Because psoriatic arthritis is a multisystem disease, care is often coordinated with:
- Dermatology for psoriasis and nail disease
- Gastroenterology for associated inflammatory bowel disease
- Ophthalmology for inflammatory eye involvement
This collaborative approach ensures comprehensive, integrated care and optimal outcomes.
When to Refer for Suspected Psoriatic Arthritis
Referral to rheumatology is recommended for patients with psoriasis who develop:
- Persistent joint pain, swelling, or stiffness
- Dactylitis or enthesitis
- Inflammatory back pain
- Nail disease with musculoskeletal symptoms
- Ocular inflammation or known IBD with joint symptoms
- Unexplained inflammatory arthritis, even without known psoriasis
Why See a Rheumatologist?
Rheumatologists are uniquely trained to:
- Diagnose psoriatic arthritis across multiple disease domains
- Select targeted biologic therapies based on individual disease patterns
- Coordinate multidisciplinary care
- Monitor long-term disease activity and treatment safety
