Psoriasis, a common chronic inflammatory skin disease affecting approximately 2-3% of the global population, frequently co-occurs with depression. This highly prevalent comorbidity significantly impairs patients' quality of life. Despite the substantial physical and mental health burden imposed by psoriatic depression, the underlying pathophysiological mechanisms connecting psoriasis and depression remain poorly understood. In this review, we explored several pathological processes that may cont

Prolonged glucocorticoid therapy may lead to adrenal insufficiency (AI) or even adrenal crisis (AC) due to suppression of the hypothalamic-pituitary-adrenal (HPA) axis. This case report describes a male patient with psoriasis who had received long-term irregular glucocorticoid therapy for psoriasis management. Following an upper respiratory tract infection, the patient developed generalized skin lesions accompanied by systemic symptoms including abdominal pain, vomiting, fatigue, fever, and leth

Plaque psoriasis is an immune-mediated chronic recurrent skin disease. In recent years, 308 nm excimer laser (308 nm EL) and topical tacrolimus have been widely used to treat psoriasis. The purpose of this study was to evaluate the efficacy of 308 nm EL irradiation combined with 0.1% tacrolimus ointment in the treatment of plaque psoriasis. This study was a retrospective observational study involving 100 patients with plaque psoriasis, divided into two groups: the control group (50 cases) was tr

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis involving axial and peripheral joints and tendons that affects a subset of patients with psoriasis (PsO). PsA can be a debilitating disease and warrants prompt rheumatologic evaluation and management. The diagnosis of PsA can be challenging for the practising dermatologist as there is often an overlap in the symptoms of PsA and non-inflammatory musculoskeletal conditions such as osteoarthritis, tendonitis and myofascial pain. The prim

Emerging evidence indicates that omega-3 fatty acids from fish oil may serve as beneficial dietary supplements for psoriasis management. Clinical observations demonstrate a significant association between psoriasis improvement and increased docosahexaenoic acid (DHA) levels. However, the causal relationship between fatty acids and psoriasis risk requires further investigation. Using summary-level genome-wide association study (GWAS) data, we applied univariable (UVMR), reverse, and multivariable

Pustular psoriasis is a rare and severe variant of psoriasis characterized by the eruption of sterile pustules, which may present in distinct clinical patterns. The pathologic features of psoriasis, including keratinocyte hyperproliferation, neutrophilic infiltration, and immune dysregulation, are markedly accentuated. Generalized pustular psoriasis (GPP) displays clinical heterogeneity in age of onset, severity, and disease course. Several overlapping phenotypes are recognized. A variable relat

Introduction Psoriasis is a chronic immune-mediated disease that significantly impacts patients clinically and psychologically. Physician-assessed severity measures, including Psoriasis Area and Severity Index (PASI), Body Surface Area (BSA), and Physician Global Assessment (PGA), often fail to capture patient-reported outcomes, particularly when clinical improvement and perceived quality-of-life gains are misaligned.Purpose To clarify the association between clinical improvements and Dermatolog

Previous research suggests that patients with hidradenitis suppurativa (HS) may face a higher risk of serious infections compared with those with psoriasis. However, these studies are subject to limitations that could constrain their reliability. To compare the risk of hospitalization from noncutaneous infections, infection profiles, and the length of stay (LOS) of adult patients with HS and psoriasis treated with adalimumab. This retrospective cohort study was conducted using deidentified claim

Abstract Background: Psoriasis vulgaris, particularly when manifesting in highly visible regions such as the face and hands, can profoundly impair self-perception and social functioning. Despite a growing interest in psychodermatology, the specific impact of visible psoriatic lesions on social appearance anxiety remains insufficiently explored. Objective: To assess the severity of social appearance anxiety in patients with visible psoriasis vulgaris lesions compared to healthy controls, and t

Psoriasis is a chronic skin disorder with significant individual and societal impacts. Current therapies often lack efficacy, are costly, or cause side effects, necessitating new treatments. This study explores regenerative therapies-exosomes, mesenchymal stem cells (MSCs), epigallocatechin-3-gallate nanoparticles (EGN), and EGN-loaded exosomes (EGN-Exo)-in regulating psoriasis-related markers (IL-6, IL-4, Bcl-2, Bax, NF-κB, CDC25B). An imiquimod-induced psoriasis model in Wistar rats was used,

Psoriasis is an autoimmune inflammatory condition that often intersects with orthopaedic care due to its connection to psoriatic arthritis. However, not all psoriasis patients develop psoriatic arthritis. Psoriasis patients may undergo hip or knee arthroplasties for reasons unrelated to psoriasis. This condition, marked by inflamed, scaly skin caused by an overactive immune system, may pose challenges for orthopaedic surgeries. This systematic review evaluated outcomes for psoriasis patients aft

Psoriasis is a chronic immune-mediated skin disorder characterized by excessive keratinocyte proliferation, inflammation, and oxidative stress. This study investigates the role of the JNK/c-Jun cascade in psoriasis pathogenesis, focusing on its impact on keratinocyte proliferation and inflammatory responses. An in vitro psoriasis model was established using M5-stimulated HaCaT keratinocytes, while an in vivo model was created with imiquimod-treated Wistar rats. The results indicated that M5 stim

Background Psoriasis is a chronic inflammatory disease associated with multiple comorbidities, including metabolic syndrome and cardiovascular disease. Although specific dietary interventions, such as intermittent fasting and caloric restriction, have been shown to ameliorate inflammation and promote weight loss, the effect of these interventions independent of weight loss remains unclear. Time-restricted eating (TRE), a type of intermittent fasting, limits the daily eating window to a fixed num

Background Psoriasis is a persistent inflammatory skin condition. Several studies have revealed that obesity significantly contributes to both the initiation and advancement of psoriasis. The metabolic score for visceral fat (METS-VF) represents an innovative measure designed to forecast visceral obesity, integrating factors such as insulin resistance metabolic score, waist-to-hip ratio (WHR), age, and gender. The present study aimed to investigate the association between METS-VF and psoriasis p

Ixekizumab is a monoclonal antibody used in the treatment of moderate-to-severe psoriasis and psoriatic arthritis by targeting interleukin-17 A (IL-17 A). It has demonstrated efficacy in controlling inflammation in autoimmune diseases, though adverse reactions can arise. This case study reports a case of 25-year-old female with psoriatic arthritis undergoing treatment with ixekizumab, who developed acute enlargement and inflammation of a pre-existing sebaceous cyst located posterior to the left

Psoriasis is a chronic inflammatory skin disease driven by immune dysregulation and often exacerbated by metabolic comorbidities. Glucagon-like peptide-1 receptor agonists (GLP-1RAs), initially developed for type 2 diabetes mellitus (T2DM) and weight management, have emerged as a promising treatment due to their anti-inflammatory and immunomodulatory properties. This review evaluates the clinical efficacy, mechanisms of action, and limitations of GLP-1RAs, such as liraglutide, exenatide, and sem

Background/purpose While biologics and small-molecule inhibitors are first-line systemic treatments for psoriasis, phototherapy remains an alternative for patients unable to access these treatments because of medical or financial constraints. Narrow-band ultraviolet B (NB-UVB) is effective for localized psoriasis but less so for extensive disease. To address this limitation, bathwater delivery of psoralen plus ultraviolet A (bath-PUVA) was introduced in 2004. This study evaluates the efficacy, s

Psoriasis is a common chronic inflammatory skin disease that significantly affects patients'quality of life. There is no cure for psoriasis, and available treatments are not completely effective. We have previously found that hydroxytyrosol (HT) has anti-psoriatic effects in vitro. In the present study, we aimed to investigate the therapeutic effects of HT on psoriasis in vivo and to explore the underlying mechanisms. We explored the effects and molecular mechanisms of HT on imiquimod (IMQ)-indu

Background Genetic susceptibility to psoriasis involves multiple loci, including TYK2 (Tyrosine Kinase 2), which is associated with various autoimmune diseases. However, its specific role and mechanisms in psoriasis remain unclear. This study aimed to identify psoriasis-associated proteins using Summary-based Mendelian Randomization (SMR) and to explore their regulatory mechanisms.Methods SMR analysis integrating pQTL data was conducted to identify proteins linked to psoriasis, revealing ICAM1 (
