Study Notes
Biological Therapies and Bariatric Surgery
- Biological therapies (biologics) show less efficacy in some cases, with studies indicating a beneficial effect of bariatric surgery on psoriasis.
- Individual educational interventions can improve management outcomes, though they may be challenging in resource-limited settings.
Treatment Strategies for Plaque Psoriasis
- Treatment plans should consider psoriasis severity, presence of psoriatic arthritis, associated medical conditions, and patient preferences.
- Narrowband ultraviolet B (NB-UVB) radiation effectively treats plaque psoriasis, though it carries risks of burning and a lower potential for photocarcinogenesis compared to photochemotherapy.
- Treatment goals often aim for a psoriasis area severity index (PASI) score of 2 or less, or similar assessments indicating a 90% reduction from baseline.
Oral Systemic Therapies
- Before biologics emerged, oral systemic treatments were the primary option for moderate-to-severe plaque psoriasis.
- Patients eligible for systemic therapy generally have psoriasis covering more than 10% of their body surface area or have not responded to topical treatments.
- Commonly used oral agents include methotrexate and cyclosporine, but adherence to topical therapies remains a challenge due to their extensive use and side effects.
Topical Therapy
- Emollients should be liberally applied to all patients as a foundational treatment.
- Topical therapies remain an option for patients with limited psoriasis affecting less than 3-5% of their body surface area.
- Common topical agents include corticosteroids and anthralin, along with modern cosmetic options that prioritize appearance.
Phototherapy
- Ultraviolet radiation serves an immunosuppressive role locally, impacting the severity of psoriasis.
- Practice guidelines have evolved to assess treatment options concurrently rather than sequentially, reflecting the need for more immediate and effective management.
