Research Article: Effectiveness of Brodalumab in Patients with Moderate-to-Severe Plaque Psoriasis Located in Difficult-to-Treat Areas

Date Published: 2023-09-25

Abstract:
Psoriasis is a chronic inflammatory skin disease, affecting up to –% of the worldwide population. Despite several clinical phenotypes may be distinguished, plaque psoriasis is the most common, accounting for % of cases and presenting as sharply demarcated erythematous plaques covered by silvery-white lamellar scales., Psoriasis management is challenging, particularly for moderate-to-severe forms of the disease. Moreover, several comorbidities (e.g psoriatic arthritis, inflammatory bowel disease, cardiovascular diseases, obesity, psychological and psychiatric disorders, uveitis, etc.) may be associated with psoriatic disease, necessitating early treatment to prevent systemic complications., Recently, the introduction of biologics revolutionized the treatment scenario., Indeed, recent knowledge on psoriasis pathogenesis has led to the development of selective biologic drugs, interfering with the action of cytokines such as Tumor Necrosis Factor (TNF) ?, interleukin (IL)- and IL- by inhibiting the activation of the inflammatory cascade at various levels. In particular, IL- is a family of cytokines that consists of homodimers from IL--A to IL--F and an IL--AF heterodimer., IL--A plays a crucial role in the pathogenesis of psoriasis and is the selective target of drugs such as ixekizumab and secukinumab., Moreover, IL--F has been shown to contribute to psoriatic inflammation by becoming the target of the joint blockade together with ILA by bimekizumab.– However, other isoforms such as IL--E and IL- -C also seem to play an important role in certain components of psoriatic symptoms such as itching., Of note, the A-type receptor for IL- acts as a common coreceptor for all IL- isoforms. Thus, the selective blockade of the receptor rather than the cytokine allows the advantages of simultaneous inhibition of all the IL- isoforms.,
