Published: April 2016

Psoriasis is a chronic skin disorder affecting approximately 2% of the European and American population. The most common form of psoriasis is the chronic plaque type. Inverse psoriasis, also named flexural or intertriginous psoriasis, is not considered a separate disease entity but rather a special site of involvement of plaque psoriasis, characterized by its localization to inverse/intertriginous/flexural body sites. We review current evidence and establish whether inverse psoriasis is a separate disease entity based on characteristics in terms of epidemiology, pathogenesis, clinical and histologic presentation, microbiology, and treatment.

Background: Psoriatic arthritis (PsA) is a common comorbidity in patients with psoriasis (PsO) that leads to significant disease burden. Biologic therapies targeting the interleukin (IL)-23/IL-17 axis have been widely used for PsO, but their comparative effectiveness in preventing PsA remains unclear.

Objective: The study objective was to compare the occurrence of developing incidental PsA among PsO patients treated with interleukin-23 inhibitors (IL23is) or interleukin-17 inhibitors (IL17is).

Chronic inflammatory diseases show significant heterogeneity in their phenotypes, with diverse immune cells and mediators interacting in response to various stimuli. This review proposes the concept of the 'inflammazone' framework - which maps the distribution of immune components driving disease pathogenesis - using sarcoidosis and psoriasis as examples. Sarcoidosis features granulomatous inflammation with macrophages and CD4 T cells, which can spread to lymph nodes and other organs.

Interleukin-17: A pleiotropic cytokine implicated in inflammatory, infectious, and malignant disorders.

IL-17A, referred to as IL-17, is the founding member of a family of pro-inflammatory cytokines, including IL-17B, IL-17C, IL-17D, IL-17E (or IL-25), and IL-17F, which act via receptors IL-17RA to IL-17RE, and elicit potent cellular responses that impact diverse diseases. IL-17's interactions with various cytokines include forming a heterodimer with IL-17F and being stimulated by IL-23's activation of Th17 cells, which can lead to inflammation and autoimmunity. IL-17 is implicated in infectious diseases and inflammatory disorders such as rheumatoid arthritis and psoriasis, promoting neutrophil recruitment and anti-bacterial immunity, but potentially exacerbating fungal and viral infections, revealing its dual role as protective and pathologic.

Extracting natural active ingredients from plants is an effective way to develop and screen modern drugs. Psoralea corylifolia is a leguminous plant whose seeds have long been used as a Traditional Chinese Medicine to treat psoriasis, rheumatism, dermatitis, and other diseases. To date, several main compounds, including coumarins, flavonoids, monoterpene phenols, and benzofurans, have been identified from the seeds of Psoralea corylifolia.

Multiple parameters define the treatment course with biologics for a psoriatic patient while treatment switches are often associated with worse prognosis. The purpose of this study was to describe the switching patterns of biologics for psoriasis in the Greek market landscape and to detect associated factors that may impact the evolvement of selected therapy. This is a retrospective cohort study using data recorded in the nationwide digital prescription database of Greece.
