Psoriasis continues to affect a large percentage of patients worldwide and strongly appears to be a systematic disease. Efforts are being made to understand its etiology, which have led to research extended to genomic analysis with a focus on the role of pro-inflammatory cytokines, which play a major role in the pathogenesis of the disease. Plasma proteomic analysis in various diseases has provided promising results for choosing the right treatment for psoriasis, suggesting that it could play a key role in the prevention, prognosis, and treatment of the disease by individualizing treatment choices based on the proteomic profile of each patient. In this review, we focus on existing data in the bibliography on proteomic analysis in psoriasis and relevant approaches to future targeted therapies.Psoriasis remains a chronic inflammatory condition of the skin and joints. It is estimated to affect millions of people worldwide; however, its aetiology has still not been fully elucidated. Apparently, it is a multifactorial disease influenced by exogenous and endogenous factors, which define the clinical symptoms, signs, and severity of the disease (1).The incidence of this condition in Caucasian children has significantly increased over time, with the chronic plaque type appearing to dominate (73.7%). The extremities (59.9%) and the scalp (46.8%) are the most affected sites. The incidence of the disease increases with age; however, it is not different between both sexes (2). A recent German study showed a rise in incidence in men compared to women, peeking in midlife, and declining from the age of 60, in both sexes (3). It seems that the annual incidence of this disease has increased in the last 40 years for unknown reasons; changes in the diagnostic patterns developed recently could be one factor (4). It is important to note that, psoriasis ranks second in the list of diseases associated with depression (5).Many studies have investigated psoriasis and its role in the systemic comorbidities such as: cardiometabolic diseases (6, 7), gastrointestinal diseases (8, 9) chronic kidney disease (CKD) (10), malignancy (11), infection (12, 13), mental health issues (14, 15), and psoriatic arthritis (PsA) ( 16). Severe psoriasis is associated with an increased risk of death, primarily due to cardiovascular events (17). Overweightness and obesity, more common among psoriatic patients, increase the severity the disease (18). In 1961, Reed et al. first investigated the high prevalence of thrombosis or myocardial infarction (MI) in necropsy material from psoriatic arthritis patients (19). During the last decades, there has been increasing epidemiological evidence supporting the identification of more systemic diseases as extracutaneous medical conditions related to psoriasis. For example, eye manifestations and complications can be seen in psoriasis arthritis patients, symptoms usually not investigated by physicians (20, 21). There is an increasing prevalence of comorbidities associated with psoriasis on a global scale 1000
