Pathway Overview
15 steps
Algorithm Steps
15 total
01Start 02Action Overarching Principles
Key principles for PsA management
- Treatment goal: remission or low disease activity (MDA, DAPSA)
- Shared decision-making with patient
- Address ALL domains: peripheral, axial, skin, enthesitis, dactylitis
- Consider comorbidities: CV disease, metabolic syndrome, uveitis, IBD
- Multi-disciplinary care (rheum, derm, ophthalmology)
03Action Domain Assessment
Identify predominant manifestations
- Peripheral arthritis: joint count, swelling
- Axial involvement: inflammatory back pain, limited mobility
- Skin/nails: PASI score, BSA, nail dystrophy
- Enthesitis: LEI, MASES scores
- Dactylitis: digit count
04Decision Mild Disease?
Few joints, mild skin, no poor prognostic factors
- Poor prognostic factors: polyarticular, structural damage, elevated CRP/ESR, dactylitis
- Mild: oligoarticular, no erosions, mild skin involvement
- Yes - mild
05Action NSAIDs (Short-Term Only)
For mild PsA
- NSAIDs monotherapy ONLY for mild disease and short-term
- NOT long-term monotherapy
- If poor prognostic factors: start csDMARD rapidly
- Oral GC NOT recommended (may flare psoriasis)
06Decision Target Achieved at 3-6 Months?
Assess all domains
- MDA (Minimal Disease Activity): 5/7 criteria
- DAPSA remission (≤4) or low activity (≤14)
- If one domain uncontrolled: escalate based on that domain
- Yes - target met
07Action Maintenance Therapy
Sustained remission or MDA
- Continue effective therapy
- May consider cautious dose reduction in sustained MDA
- Do NOT stop bDMARD (relapse risk)
- Continue csDMARD if using combination
- Monitor all domains regularly
08Outcome PsA Controlled
MDA or remission achieved across all domains
- No - escalate
09Action bDMARD Therapy
After csDMARD failure
- TNF inhibitor (adalimumab, etanercept, infliximab, certolizumab, golimumab)
- IL-17 inhibitor (secukinumab, ixekizumab, bimekizumab)
- IL-23 inhibitor (guselkumab, risankizumab) - especially if skin predominant
- Ustekinumab (IL-12/23) - less preferred unless skin-predominant
- Consider skin severity in selection (IL-17i, IL-23i excellent for psoriasis)
10Warning ⚠️ Domain-Specific Drug Selection
Comorbidities influence choice
- Axial PsA: TNFi or IL-17i (like axSpA); NOT IL-23i (limited axial data)
- IBD: TNFi (adalimumab, infliximab); AVOID IL-17i (may worsen IBD)
- Uveitis: TNFi monoclonals preferred
- Severe skin: IL-17i, IL-23i excellent; TNFi less effective for skin
11Decision bDMARD Response at 3-6 Months?
Assess all domains
- Yes - response
- Path rejoins step 07Shared downstream outcome
- No - switch
12Action Switch bDMARD or JAK Inhibitor
After bDMARD failure
- Switch to different mechanism bDMARD
- JAK inhibitors: tofacitinib, upadacitinib
- EULAR suggests JAKi AFTER bDMARD failure (safety data ongoing)
- Assess CV/VTE risk before JAKi (similar to RA)
- Response
- Path rejoins step 08Shared downstream outcome
- Failure
13Warning Specialist Referral
Refractory disease, complex comorbidities, clinical trial
- No - or poor prognosis
14Action csDMARD Therapy (Peripheral PsA)
First-line for peripheral arthritis
- Methotrexate PREFERRED (15-25 mg/week with folic acid)
- Alternative: Leflunomide, Sulfasalazine (less evidence)
- Initiate rapidly if poor prognostic factors
- csDMARDs NOT effective for axial disease
- Short-term local GC injections acceptable
15Warning ⚠️ Glucocorticoid Caution
Not recommended in PsA
- Oral GC NOT recommended (may cause psoriasis flare on withdrawal)
- If absolutely needed: low dose, short duration
- Local injections (IA, peritendinous) acceptable
- Enthesitis: steroid injection controversial
- Path rejoins step 06Shared downstream outcome
