Clinical Scorecard: Psoriasis–AD Switching May Mimic Treatment Failure
At a Glance
| Category | Detail |
|---|---|
| Condition | Psoriasis and Atopic Dermatitis |
| Key Mechanisms | Persistent, treatment-associated phenotype switching between psoriasis and atopic dermatitis due to immune rebalancing. |
| Target Population | Patients with psoriasis or atopic dermatitis undergoing systemic or biologic therapy. |
| Care Setting | Multicenter dermatology clinics across multiple countries. |
Key Highlights
- 101 patients developed eczematous features while treated for psoriasis.
- 47 patients developed psoriasiform disease while treated for atopic dermatitis.
- Switching often occurred during treatment with interleukin-17 or interleukin-23 inhibitors.
- Janus kinase inhibitors were the most frequently documented management strategy.
- Clinical severity scores improved following therapeutic adjustment.
Guideline-Based Recommendations
Diagnosis
- Sustained phenotype switching should be considered when patients develop opposing features.
Management
- Therapeutic adaptation may include broader immunomodulatory approaches such as Janus kinase inhibition.
Monitoring & Follow-up
- Clinical severity scores should be monitored following treatment modification.
Risks
- Potential misclassification of treatment failure if phenotype switching is not recognized.
Patient & Prescribing Data
Patients with psoriasis or atopic dermatitis experiencing phenotype switching.
60% of patients with psoriasis-to-eczematous switching were switched to a Janus kinase inhibitor.
Clinical Best Practices
- Recognize sustained phenotype switching to avoid misclassifying treatment failure.
- Consider patient history and comorbidities when managing treatment.
