Definition & Terminology
Formal Definition
### Formal Medical Definition
Psoriatic arthritis is a chronic, inflammatory, seronegative spondyloarthritis that occurs in association with psoriasis. It is characterized by peripheral arthritis, often asymmetric; enthesitis; dactylitis; and axial involvement. The disease results from immune-mediated inflammation targeting joints, entheses, and skin.
### Medical Terminology
- **Seronegative:** Rheumatoid factor negative
- **Enthesitis:** Inflammation at tendon/ligament attachment to bone
- **Dactylitis:** Swelling of entire finger or toe ("sausage digit")
- **Spondyloarthritis:** Group of inflammatory arthritis affecting spine
- **Psoriasis:** Chronic skin condition with red, scaly patches
- **Nail psoriasis:** Pitting, ridging, discoloration of nails

Anatomy & Body Systems
Joint Involvement
- Can affect any joint
- Often asymmetric
- Common sites: fingers, wrists, knees, ankles, spine
- May involve distal interphalangeal (DIP) joints
Entheses
- Where tendons/ligaments attach to bone
- Common sites: Achilles tendon, plantar fascia, elbows
- Inflammation is hallmark feature
Skin and Nails
- Psoriasis skin lesions
- Nail changes: pitting, onycholysis, hyperkeratosis
- May precede or follow joint symptoms
Systemic Features
- Fatigue
- Eye inflammation (uveitis)
- Cardiovascular risk
- Metabolic syndrome association
Causes & Root Factors
Primary Cause
Autoimmune Response
- T-cells attack healthy joint tissue
- Inflammatory cascade
- Cytokine production (TNF, IL-17, IL-23)
- Genetic predisposition
Contributing Factors
Genetics
- Family history
- Specific HLA genes
- Non-HLA genetic factors
Environmental Triggers
- Infections (streptococcal)
- Trauma
- Stress
- Medications
Risk Factors
Risk Factors
- Psoriasis: Primary risk factor
- Family history: Increases risk
- Age: 30-50 years typical
- Nail psoriasis: Increases PsA risk
Protective Factors
- Not well established
- Early treatment of psoriasis may help
- Healthy lifestyle
Signs & Characteristics
Arthritis Patterns
- Asymmetric oligoarthritis: Most common
- Symmetric polyarthritis: Like rheumatoid arthritis
- DIP predominant: Fingers only
- Arthritis mutilans: Severe, destructive form
- Axial disease: Spine involvement
Symptoms
- Joint pain and swelling
- Morning stiffness (>30 minutes)
- Fatigue
- Reduced range of motion
Enthesitis
- Heel pain (Achilles)
- Sole of foot pain
- Elbow pain
- Buttock pain
Dactylitis
- Swollen fingers or toes
- Sausage appearance
- Painful
Skin and Nails
- Psoriasis patches
- Nail pitting
- Nail separation
- Nail thickening
Associated Symptoms
Eye Inflammation
- Uveitis
- Conjunctivitis
- Iritis
Other Associations
- Cardiovascular disease
- Metabolic syndrome
- Osteoporosis
- Depression
Complications
- Joint damage
- Disability
- Reduced quality of life
- Cardiovascular disease
Differential Diagnosis
Rheumatoid Arthritis
- Usually symmetric
- Rheumatoid factor positive
- No skin/nail involvement
- Different treatment
Ankylosing Spondylitis
- Primarily spine
- HLA-B27 positive
- No skin involvement
Gout
- Acute attacks
- Uric acid elevated
- Different joint distribution
Osteoarthritis
- No inflammation
- Older age
- Different pattern
Conventional Treatments
Medications
NSAIDs
- Pain relief
- Reduce inflammation
- For mild symptoms
DMARDs
- Disease-modifying antirheumatic drugs
- Methotrexate first line
- Sulfasalazine
- Leflunomide
Biologics
- TNF inhibitors (etanercept, adalimumab)
- IL-17 inhibitors (secukinumab)
- IL-23 inhibitors (guselkumab)
- JAK inhibitors (tofacitinib)
Treatment Goals
- Reduce symptoms
- Prevent joint damage
- Improve quality of life
- Achieve remission

- Pace activities
- Rest during flares
Skin Care
- Moisturize regularly
- Treat psoriasis
- Protect skin
Lifestyle
- Maintain healthy weight
- Don't smoke
- Limit alcohol
- Manage stress
Prevention
No Proven Prevention
- Cannot prevent PsA if genetically susceptible
- Early treatment of psoriasis may reduce risk
Early Detection
- Regular skin checks
- Report joint symptoms
- Monitor for nail changes
Lifestyle
- Healthy weight
- Regular exercise
- Stress management
When to Seek Help
Seek Evaluation If
- Joint pain with psoriasis
- New joint symptoms
- Stiffness >30 minutes
- Swelling in joints or fingers/toes
Red Flags
- Severe pain
- Joint deformity
- Significant disability
- Systemic symptoms
Prognosis
Disease Course
- Chronic, lifelong condition
- Usually progressive without treatment
- Flare-ups and remissions
With Treatment
- Most achieve good control
- Can slow or halt progression
- Improved quality of life
Prognosis Factors
- Early treatment = better outcomes
- Severe skin disease = more severe arthritis
- Some develop disability
FAQ
Is psoriatic arthritis the same as rheumatoid arthritis?
No, they're different. PsA occurs with psoriasis, involves enthesitis and dactylitis, often affects DIP joints, and is rheumatoid factor negative.
Will I need medication forever?
Most patients require ongoing medication to control the disease. Treatment goals include achieving remission, which may allow medication reduction in some cases.
Can diet help?
While no diet cures PsA, anti-inflammatory foods may help reduce symptoms. Some find certain foods trigger flares.
Does it affect life expectancy?
With modern treatments, life expectancy is normal. However, associated cardiovascular and metabolic conditions may affect overall health.
Can exercise help?
Yes, regular exercise maintains joint mobility, strengthens muscles, and improves overall health. Low-impact activities are recommended.
