Increasing Access to Effective Systemic Treatments in Patients with Moderate-to-Severe Psoriasis: Narrative Review

Psoriasis is a chronic, immune-mediated inflammatory disease with a worldwide prevalence ranging between 0.51 and 11.43%. It results in a large clinical and social burden, with patients frequently suffering from reduced quality of life, psychologic distress and debilitating comorbidities. Biologic agents are used to establish and maintain disease control in patients with moderate-to-severe psoriasis and are essential to improving quality of life. However, a substantial proportion of patients have limited access to therapy due to economics, health policies and clinical considerations, which creates clinical unmet needs that disadvantage both patients and healthcare professionals. Biosimilars are a cost-effective alternative to off-patent biologic therapies, and there is mounting evidence to suggest they offer a valuable pharmacoeconomic strategy to lower healthcare costs in patients with psoriasis. Furthermore, the introduction of biosimilars can increase the number of patients able to receive biologics, allowing these patients to be treated earlier in the disease course, potentially modifying the course of their disease and reducing the risk of comorbidities. In time, the emergence of additional data, particularly those related to long-term safety, efficacy in extrapolated indications and the effects of switching, should reassure physicians and help overcome the final hurdles for a wider implementation of biosimilars. This review aims to provide an overview of current treatment approaches for patients with moderate-to-severe psoriasis in the biosimilars era and explores both the current challenges and potential opportunities to improve access to high-quality, effective treatments.

Advanced Glycation End Products and Psoriasis

Advanced glycation end products (AGEs) are biologically active compounds formed physiologically throughout a sequence of chemical reactions, to generate highly oxidant-reactive aldehydes that combine covalently to proteins. They accumulate slowly in tissues during ageing but also in metabolic and selected inflammatory disorders. Accumulation of AGEs occurs more rapidly and intensely in the skin and serum of patients with type 2 diabetes, obesity, cardiovascular diseases, chronic renal insufficiency, and non-alcoholic fatty liver disease and also in the skin of patients with psoriasis. All of the above conditions are intimately associated with psoriasis. Interaction of AGEs with their receptors (RAGEs) stimulates cellular signaling with the formation of reactive oxygen species and activation of nuclear factor kappa light chain enhancer of activated B (NF-kB), which is a key regulator in the expression of inflammatory mediators and the production of oxidative stress. Thus, AGEs may play an interesting pathogenic role in the intersection of inflammatory and metabolic diseases, may represent a biomarker of inflammation and a potential target for novel therapeutic strategies. This is a narrative review with the objective to summarize current evidence on the role of AGEs in psoriasis.

Tailored biological treatment for patients with moderate-to-severe psoriasis

INTRODUCTION

Psoriasis is a common, chronic immune-mediated skin disease frequently associated to inflammatory and metabolic comorbidities. About 20-30% of patients are affected by moderate-to-severe psoriasis and require a systemic treatment, which include traditional and biological drugs. The objective of this manuscript is to provide criteria for a personalized biological treatment.

AREAS COVERED

Tailoring a biological treatment for patients with moderate-to-severe psoriasis needs to consider several variables related to the disease, the patient and the treatment. It is important to consider the disease severity and activity, the skin areas involved, the frequency of relapses, itch or other symptoms, and foremost the presence of comorbidities. About the patient, is important to consider age, gender, body weight, the occupation, the impact on the quality of life, the likelihood of adherence, patient expectations, the desire for remission, and the fear of side effects.

EXPERT OPINION

The presence of comorbidities, which may benefit from or contraindicate a given biologic, is the main driver of a tailored therapy. A personalized treatment associates maximum efficacy and minimal risk of side effects. In addition, there is the possibility of modifying disease-course inducing long-term remission and preventing the development of psoriatic arthritis.
