[Dithranol and combined treatment procedures: pro and con]
Summary
Combining therapies like dithranol with tar or UV light can improve psoriasis treatment. Newer combinations with retinoids offer high effectiveness and potentially reduce long-term side effects.
Area of Science:
- Dermatology
- Phototherapy
- Pharmacology
Context:
- Psoriasis treatment requires balancing efficacy with patient acceptance and safety.
- Traditional therapies like dithranol and Goeckerman have established safety profiles but varying effectiveness.
- Photochemotherapy (PUVA) is effective but reserved for severe cases due to potential risks.
Purpose:
- To evaluate the efficacy and tolerability of various combination therapies for psoriasis.
- To compare traditional regimens with newer combinations involving retinoids and UV irradiation.
- To identify optimal treatment strategies for psoriasis management.
Summary:
- Combination of dithranol with tar (CSVT) enhances antipsoriatic effects but has lower patient acceptance.
- Goeckerman therapy (tar + UV) is better tolerated but less effective than CSVT.
- Aromatic retinoid combinations with UVB (ReSUP) or PUVA (RePUVA) are highly effective, with ReSUP preferred for routine use due to potentially reduced long-term risks.
Impact:
- Identifies ReSUP as a preferred regimen for routine psoriasis treatment, balancing efficacy and safety.
- Provides evidence for optimizing combination therapies to improve patient outcomes.
- Highlights the role of retinoids in mitigating UV-related risks in psoriasis treatment.
