Psoriasis is a chronic systemic inflammatory skin disorder that is strongly associated with metabolic disorders, including obesity, insulin resistance, hypertension, and dyslipidemia. Dyslipidemia causes abnormalities in lipid profiles, such as elevated triglycerides or low density lipoprotein (LDL) levels. Measure maternally expressed gene 3 (MEG3) and microRNA-147b in serum of patients with and without dyslipidemia compared to healthy control. These measurements were compared with clinical cha

Although post-translational modifications (PTMs) significantly influence the pathogenesis of psoriasis, their specific mechanisms remain poorly understood. This study aimed to identify novel PTM-targeted therapeutic avenues for the precision treatment of psoriasis. Nine psoriasis-related datasets GSE13355, GSE14905, GSE30999, GSE41664, GSE51440, GSE53552, GSE54456, GSE117239, and GSE226244 were obtained. Consensus clustering was performed to identify psoriasis subtypes. Then, the study proceeded

Background and aims Lipid dysregulation plays a crucial role in psoriasis pathogenesis and its cardiometabolic comorbidities. Novel anthropometric indices such as Body Roundness Index (BRI), Lipid Accumulation Product (LAP), and Triglyceride-Glucose (TyG) index have been proposed to better reflect underlying metabolic dysfunction and may be associated with psoriasis risk, severity, and related complications. This systematic review evaluates the current evidence on the associations of BRI, LAP, a

Drug exposure is one of the potential mechanisms implicated in the onset or exacerbation of psoriasis. To date, several cardiovascular agents have been implicated. Sacubitril/valsartan (SV) has been widely used in the treatment of hypertension and heart failure (HF). Its common adverse reactions include angioedema, hypotension, renal impairment, and hyperkalemia. However, SV may cause psoriasis, which needs clinical attention. This report describes a case of a middle-aged male patient who develo

High-impact site plaque psoriasis is difficult to treat. Icotrokinra, an oral peptide with high specificity for the interleukin (IL)-23 receptor, demonstrated significantly higher rates of high-impact site psoriasis clearance, versus placebo, with no safety signals, through Week (W)16. Report clinical response rates and safety through 1 year of icotrokinra treatment in participants with high-impact site plaque psoriasis. Participants (≥12 years of age; psoriasis body surface area ≥1%; Investigat

Subclinical inflammation (SI) is clinically relevant in psoriasis (PsO) and psoriatic arthritis (PsA), but quantitative imaging biomarkers are lacking. We evaluated the feasibility of ultrashort echo time (UTE) bicomponent MRI for quantifying Achilles enthesis SI. Conventional MRI showed no group differences, whereas short T2* (T2*s) values were significantly elevated in PsO/PsA compared with healthy volunteers. These findings support the feasibility of UTE bicomponent analysis, as a promising t

Activated mast cells (MCs) are crucial effectors in the initiation and progression of psoriasis by secreting inflammatory mediators. The MC activation mediated by Mas-related G-protein-coupled receptor X2 (MrgprX2) has been implicated in psoriasis progression. However, the therapeutic strategies targeting MrgprX2 for psoriasis treatment remain less explored. Alkannin (Alk) is the main active component of the plant Arnebia euchroma and exhibits significant anti-inflammatory activities. However, i

This pilot study aims to describe clinical and subclinical joint and nail abnormalities in children with psoriasis.Methods Children with psoriasis and healthy controls underwent ultrasound examination of various joints, entheses, and nails. Using a standard acquisition protocol, images were obtained in both B-mode an

Introduction Obesity contributes to inflammation and may decrease psoriasis treatment efficacy. We investigated whether obesity affects the efficacy and safety of tildrakizumab, an anti-interleukin-23 p19 antibody approved for the treatment of adults with moderate-to-severe plaque psoriasis, for scalp psoriasis treatment.Methods This was a subgroup analysis of a randomized, double-blind, placebo-controlled, Phase 3b trial in patients with moderate-to-severe plaque psoriasis affecting the scalp.

Objectives Plaque psoriasis frequently involves high-impact anatomical sites such as the scalp, nails, and palmoplantar regions, which are associated with significant functional impairment and reduced quality of life. Evidence on the long-term effectiveness of biologic therapies in these locations in real-world settings remains limited. This study aimed to evaluate the real-world effectiveness and safety outcomes of risankizumab in achieving complete clearance of psoriasis affecting high-impact

Background Patients with psoriasis (PsO) are at increased risk of developing psoriatic arthritis (PsA). Emerging evidence suggests that biologic therapies may differentially influence the development of PsA; however, there are no data on the relative ability of second-line biological therapy to prevent PsA.Aim To evaluate the impact of biologic therapy on the risk of incident PsA in patients with PsO with a focus on second-line biologic therapy.Methods We identified 2819 patients who initiated b

Background Linear psoriasis is a rare variant of psoriasis characterized by erythema and scaling along the Blaschko lines. Its pathogenesis remains unknown.Objective To investigate the molecular and immunological mechanisms of linear psoriasis through gene mutation analysis and in vitro experiments and identify potential combined therapeutic targets for psoriasis.Methods Whole-exome sequencing was performed on linear lesion, clinically normal skin, and peripheral blood from linear psoriasis pati

IL-36γ is highly expressed in psoriatic skin lesions and promotes neutrophil infiltration through the induction of neutrophil chemotactic chemokines. While IL-36γ has been established to play an important role in the pathogenesis of psoriasis, its localization in the psoriatic epidermis has not been fully elucidated, and the difference in its expression patterns among other inflammatory skin diseases remains unclear. We investigated IL-36γ localization using immunohistochemistry in skin specimen

Psoriasis is a chronic skin disease characterized by keratinocyte hyperproliferation and inflammation, largely driven by the cytokines IL-22 and interferon (IFN)-γ. These cytokines activate the signal transducer and activator of transcription (STAT) 3 and STAT1 molecular pathways, leading to abnormal proliferation, impaired differentiation, and increased production of inflammatory mediators in keratinocytes. While the IL-22/STAT3 pathway primarily promotes de-differentiation in keratinocytes, IF
