RESUMO
BACKGROUND: Psoriasis is one of the most frequent chronic inflammatory skin diseases and has a negative impact on the interpersonal relationship and psychosocial well-being. The aims of this study were to examine the effects of intensity of pruritus on quality of life and depression, to investigate the relationship between anger, self-esteem, and depression, and to compare patients with early and late onset of psoriasis. As our study was carried out during the COVID-19 pandemic, we aimed also to investigate the safety concerns and anxiety related to COVID-19 in psoriasis patients. METHODS: This cross-sectional study included 137 patients diagnosed with plaque psoriasis. The patients were classified as early-onset (age < 30 years) and late-onset psoriasis (age ≥ 30 years). Duration of disease, pruritus scores, and socio-demographic characteristics were recorded. Measures included the State-Trait Anger Expression Inventory (STAXI), Rosenberg Self-Esteem Scale, Beck Depression Inventory (BDI-II), Psoriasis Disability Index (PDI), and Fear and anxiety in relationship with COVID-19 Scale were used for determining anger, anger expression style, self-esteem, depression, anxiety, and quality of life. RESULTS: The psoriasis patients had a lower score for self-esteem than the normative data from the Romanian general population. The average scores for state anger and trait anger are similar to the normative data from the Romanian general population, but the scores for anger-in and anger-out are higher. Patients with early onset had higher depression scores and lower quality of life. Self-esteem correlates negatively with depression, anger, severity of disability due to psoriasis, number of affected areas, and duration of disease. Lower level of self-esteem led to increased anger. CONCLUSIONS: Reduced self-esteem, increased anger levels, and depression are present in psoriasis patients. The effective treatment of psoriasis must, therefore, consist of a multidisciplinary approach, in which the personalized treatment of the skin condition is as important as the adjuvant therapies that reduce the patients' stress level.
RESUMO
Psoriasis is a chronic autoimmune disease affecting over 2% of the worldwide population. From an anatomopathological point of view, psoriasis is characterized by immune cells infiltration, epidermal hyperproliferation, and abnormal keratinocyte differentiation. Understanding the pathogenesis of psoriasis will allow clinicians to manage this complex disease. Under these conditions, the application of effective treatments requires a thorough knowledge of all the pathogenetic mechanisms that lead to psoriasis. Numerous immunopathological pathways play crucial roles in the development of new therapies, such as biological therapies, which have been a breakthrough in psoriasis's treatment. Pharmacogenetics is an essential factor in the patient's response to treatment. One important pathway targeted by modern treatments is the interleukin (IL)-23∕T-helper (Th)17 axis. Like IL-17 inhibitors, IL-23 blockers are a very effective therapy for this autoimmune disease. It is considered that micro-ribonucleic acids (microRNAs) are the starting point for any autoimmune disease. Studying certain microRNA (miR) involved in the inflammatory pathway in psoriasis can find direct targets to future treatments that can even be more specific than actual biological therapies. As such, miR-210 has proven to be up-regulated in psoriasis, also leading to the up-regulation of the Th1∕Th17 axis. On the other hand, miR-187 was found to be down-regulated, influencing the outcome of psoriasis by increasing the proliferation of IL-6 stimulated keratinocytes and consecutively generating epidermal thickening. In this review, we are aiming to do an up-to-date briefing of psoriasis histopathology and pharmacogenetic factors that are considered for the accurate evaluation of treatment response.
