Impact of biologic therapy on the management of moderate to severe psoriasis: a systematic review
Keywords:
Biological Therapy, Psoriasis, Quality Of Life, BiologicsAbstract
Objective: To evaluate the impact of biological therapy in the treatment of moderate to severe psoriasis. Methods: A systematic review based on PubMed data from January 2014 to August 2024. Articles were selected according to study type, intervention, outcomes, and language. Thus, 12 articles were chosen from the 53 that focused on the efficacy and safety of immunotherapies in the treatment of patients with moderate to severe psoriasis. The selection was conducted by more than one researcher, based on the title, abstract, and full text. Results: The main outcomes of the articles were PASI (Psoriasis Area and Severity Index) response rates and patients' quality of life, measured by the DLQI. Among the studies, ixekizumab and brodalumab stood out as highly effective treatments.Discussion: The selected biologics, chosen for their high efficacy, achieved PASI 90-100 and a lower number needed to treat, demonstrating a strong therapeutic capacity by promoting the clearance of psoriatic lesions and significantly improving patients' quality of life. Conclusion: The review highlights that biological therapies, particularly Brodalumab and Ixekizumab, are highly effective for moderate to severe psoriasis, showing rapid responses. Brodalumab is superior in skin clearance, while Ixekizumab provides faster results. Secukinumab and Ustekinumab are also beneficial but less consistent. These therapies represent significant advances, improving clinical outcomes and quality of life, and should be chosen based on patient individuality, efficacy, and safety.
