However, real-world data on its use in psoriatic arthritis (PsA) are limited. This study aimed to evaluate the effectiveness and safety of BKZ over 24 weeks in a real-world setting.

Methods

A retrospective, multicenter study was conducted at two Italian rheumatology centers, enrolling adult patients with PsA who initiated BKZ treatment between January 2023 and February 2025. Clinical data were collected at baseline, week 12, and week 24.

Results

Forty patients with PsA were included. Of these, 75% had failed at least two biologic and/or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) prior to BKZ and 25/40 (62.5%) had failed at least one IL-17A inhibitor (IL-17Ai). Among these 25 patients, 32% experienced a primary failure and 68% a secondary failure. The median baseline Disease Activity in Psoriatic Arthritis (DAPSA) score was 22.9 (17.5-27.2), decreasing to 6.0 (3.1-12.8) at week 24 (p < 0.001). By week 24, 72.5% achieved DAPSA low disease activity (LDA), and 25% achieved DAPSA remission. The median swollen joint count (SJC) decreased from 3.0 (0.8-5.3) to 0.0 (IQR 0.0-1.0), and median tender joint count (TJC) decreased from 4.5 (3.0-7.3) to 1.0 (0.0-2.0) (both p < 0.001). Pain visual analog scale (VAS) and Patient Global Assessment (PGA) improved significantly, from 7.0 (6.0-8.0) and 7.5 (6.5-8.0) at baseline to 2.0 (1.0-5.0) and 2.0 (1.0-4.5) at week 24 (both p < 0.001). Skin involvement also improved, with 51.5% achieving Psoriasis Area and Severity Index (PASI) 100 by week 24. The safety profile was favorable; 15% of patients developed mild oral candidiasis, none of which required treatment discontinuation.

Conclusion

BKZ demonstrated rapid and sustained improvements in PsA symptoms in a challenging real-world population, with a favorable safety profile.

Objective

The aim of this study was to systematically review the literature to characterize the burden of pediatric psoriasis.

Methods

Papers assessing associations between pediatric psoriasis (in children <18 years old) and quality of life, physical symptoms (e.g., skin pain, itch, sleep disruption), and adverse psychological, social, and financial effects were searched with no date restrictions through July 2023. Databases searched included Ovid MEDLINE®, CENTRAL, the Cochrane Database of Systematic Reviews, and PsycInfo. Articles were excluded if they focused on comorbidities (including psoriatic arthritis/enthesitis), were of low quality, or were not in English.

Results

64 publications met eligibility criteria. Composite quality of life was the most frequently reported domain (40 publications) and was negatively impacted by psoriasis as a function of severity. Physical burdens, especially itch, occurred in 44.1-96.3% of children with psoriasis, while skin pain was less common. Psychosocial and family burdens were less frequently assessed and often with non-validated tools. Children with psoriasis participated less in social activities, but there were no clear associations between psoriasis and school performance or interpersonal relationships. Psoriasis was associated with a higher mental health burden on caregivers and greater family financial burden.

Conclusions

Psoriasis leads to high burden for pediatric patients and caregivers. Evaluation and management decisions should include and incorporate a thorough assessment of burden. Additional studies using validated tools are necessary to fully assess psychosocial and family burdens of psoriasis.

This study aims to gain insight in the perspectives of patients with psoriasis on this important subject.Methods: A cross-sectional questionnaire study including adult female and male patients with psoriasis, independent of their treatment type.Results: A total of 102 patients responded to the questionnaire (70% females, 30% males), of whom 47.1% have ever used biologic therapy. Respondents preferred dermatologists or general practitioners (GPs) as information provider. Patients would like to receive FPP information on fertility, heredity of psoriasis, use of psoriasis medication, and - specifically for females- the course of psoriasis during and after pregnancy and breastfeeding. Timing of FPP information provision was preferable at moment of diagnosis and medication changes or upon explicit request.Conclusion: Dermatologists and GPs have a crucial role in providing FPP information. The findings of this study have provided hands-on guidance for healthcare professionals to improve healthcare for both female and male patients with psoriasis in the reproductive age.

However, the optimal recommended dosage of topical drugs has not been well established.

Objectives

To investigate the effect of topical drug application quantity and treatment duration on psoriasis treatment outcome.

Methods

We conducted a post-hoc analysis of two randomized controlled trials investigating 214 patients with psoriasis using topical drugs containing corticosteroids and/or calcipotriol for up to 48 weeks. We measured the amount of topical drugs used during the study period and calculated the mean amount of applied drugs per 1% affected body surface area (BSA) divided by number of days in the study period. Improvement in severity of psoriasis was measured by Lattice-System Physician's Global Assessment (LS-PGA) (where affected BSA was divided into seven categories) from baseline to last study visit. Descriptive results were reported as counts with proportions, and as means with normality-based confidence intervals (CI). Associations were analyzed using linear regressions.

Results

Most study participants had a duration of psoriasis greater than 20 years, moderate psoriasis, and no history of using systemic psoriasis treatment. They had applied a mean of 1.0 g per 1% BSA per day (95% CI 0.9; 1.2). Daily use of topical drugs for four-weeks reduced severity of psoriasis. However, extended daily use for up to 48 weeks provided further reduction in disease severity (coefficient --0.30 (95% CI -0.51, -0.09)) and -0.73 (95% CI -1.09; -0.38) (P= 0.028). Greater amount of applied topical drugs reduced severity of psoriasis in a linear manner. Every increase of 1 g of topical drugs applied per 1% BSA per day reduced LS-PGA by 0.43 (95% CI 0.24; 0.61). Finally, patients who had never used systemic drugs experienced a greater reduction in psoriasis when applying the same mean amount of topical drugs (coefficient -0.7 (95% CI -1.1, -0.4) compared to those who had a history of taking systemic treatment (-0.3 (95% CI -0.5; -0.1), P=0.026).

Conclusions

A mean application amount of at least 1.0 g of topical drugs per 1% BSA per day seems safe and effective and can be used daily until clearance.

The Saudi Arabia Psoriasis Registry (PSORSA) was established to address long-term real-world data (RWD) on systemic and biologic therapies in the region. This observational cohort study provides a comprehensive analysis of baseline disease characteristics, comorbidities, and treatment efficacy among patients enrolled in PSORSA, with an emphasis on risankizumab.

Methods

Data were sourced from a governmental online database covering multiple healthcare centers. Patients eligible for biologics were followed at baseline and at weeks 16, 28, 40, and 52 to evaluate disease severity, quality of life, and adherence. Statistical analyses were conducted using Jamovi and R. Descriptive statistics were performed for categorical and continuous variables. p-Values < 0.05 were considered significant.

Results

The study cohort included 313 patients. Plaque psoriasis was the most prevalent clinical type (93.9%). An analysis of treatment history revealed that 39.6% of patients had prior therapy exposure, and all patients received risankizumab as a biologic therapy. At baseline, the mean Psoriasis Area and Severity Index (PASI) score was 25.49. By week 52, it had decreased to 0.358, indicating complete clearance. PASI scores showed a steady and substantial reduction over time, with an 88% reduction at week 16, 96% at week 28, 97.5% at week 40, and 98.5% by week 52, demonstrating a strong and sustained treatment effect (p < 0.001). Additionally, risankizumab exhibited a favorable drug survival profile, with many patients maintaining treatment beyond 122 weeks.

Conclusion

This study represents the first real-world assessment of risankizumab for moderate-to-severe psoriasis in Saudi Arabia. The findings demonstrate that risankizumab is an effective and well-tolerated treatment for moderate-to-severe psoriasis in this Saudi Arabian cohort. However, future studies should explore long-term safety outcomes and the comparative effectiveness of risankizumab and emerging biologics in diverse patient populations.

The effects of this treatment on skin microorganisms and microbiome-encoded metabolic pathways remain unclear.

Objectives

This was an exploratory clinical study designed to investigate whether Psoriasis is associated with skin microbiota, as well as a longitudinal cohort study aimed at revealing the effects of IL-17A inhibitor treatment on skin microbiota in Psoriasis.

Methods

In this study, we recruited 26 patients with moderate to severe psoriasis and 15 healthy controls. We collected skin microbiome samples from both greasy and dry skin regions. All samples were analyzed using 16S rDNA gene sequencing to determine the microbial profiles.

Results

Compared with healthy controls, the composition and function of skin microbiome in psoriasis patients are heterogeneous. Treatment with IL-17A inhibitors significantly increases the alpha diversity of the skin microbiota in psoriasis patients, indicating potential restoration of microbial community richness and evenness. However, this treatment does not entirely alter the taxonomic composition of the skin microbiota; rather, it shifts the relative abundance of specific microbial species, indicating that certain core microbial features remain relatively stable. Moreover, IL-17A inhibitors help adjust the functional profile of the skin microbiome in psoriasis patients, bringing it closer to that of healthy individuals.

Conclusions

Psoriasis patients exhibit significant heterogeneity in both the composition and functionality of their skin microbiota. Although IL-17A inhibitor treatment fails to fundamentally alter its taxonomic composition, this therapy effectively enhances microbial community stability by increasing alpha diversity and modulating the relative abundance of various taxa. Additionally, it adjusts the functional profile of the skin microbiota towards a healthier state, thereby contributing to the restoration of microecological balance.

Many studies suggest that obesity may influence the onset and treatment efficacy of psoriasis. Currently, increasing evidence indicates that abdominal obesity is associated with various metabolic diseases, but research on the relationship between abdominal obesity and psoriasis remains limited. This study uses advanced obesity indicators such as the conicity index and body roundness index to explore the association between abdominal obesity and psoriasis.

Methods

This study is a cross-sectional analysis that uses univariate regression analysis and weighted multivariable logistic regression to investigate the relationship between conicity index, android percent fat, body roundness index, and psoriasis. Additionally, restricted cubic spline analysis was performed to explore the nonlinear association between these indicators and psoriasis. Subgroup analysis and interaction tests were also conducted.

Results

A total of 4873 participants were included in this study. After adjusting for confounding variables, the results showed a positive correlation between conicity index, android percent fat, body roundness index, and the risk of psoriasis. When conicity index, android percent fat, and body roundness index were converted into quartiles (Q1-Q4), the risk of psoriasis in the Q4 group was significantly higher compared to the Q1 group (conicity index: p = 0.032, android percent fat: p = 0.020, body roundness index: p = 0.003). In the subgroup analysis and interaction tests, no significant interaction between the conicity index, body roundness index, and the association with psoriasis was found (p > 0.05). The results only suggest that the poverty income ratio (PIR), marital status, and alcohol consumption may influence the relationship between android percent fat and psoriasis. In addition, subgroup analysis based on age shows that the association between abdominal obesity and psoriasis is more significant in the population over 40 years old.

Conclusions

After adjusting for covariates, the study found that three abdominal obesity indicators-conicity index, android percentage fat, and body roundness index-are positively correlated with psoriasis risk, suggesting that the association between abdominal obesity and psoriasis as a comorbidity is more likely to occur, emphasizing the clinical significance of this link.

Level of evidence

Level III, Evidence obtained from well-designed cohort or case-control analytic studies.

Objective

In this systematic review and meta-analysis we aimed to evaluate the association between selected serum trace element levels (zinc [Zn], copper [Cu], iron [Fe], selenium [Se], and calcium [Ca]) and IMSDs (psoriasis, vitiligo, atopic dermatitis [AD], alopecia areata [AA], hidradenitis suppurativa, and bullous diseases).

Data sources

We conducted a comprehensive search on the PubMed, EMBASE, Scopus, China National Knowledge Infrastructure, and Web of Science databases from the database inception date to May 2, 2024. Studies measuring serum, plasma, or whole-blood levels of Zn, Cu, Fe, Se, or Ca in patients with IMSD compared to those in healthy controls were included.

Data extraction

This study followed the guidelines of the Meta-analysis of Observational Studies in Epidemiology and the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines. Two authors (X.Y.S. and Y.O.) independently reviewed the titles and abstracts of the identified studies using a standardized collection form.

Data analysis

The primary outcome was the standardized mean difference with a 95% CI in serum trace element levels (Zn, Cu, Fe, Se, and Ca) between patients with IMSDs and healthy controls. Overall, 113 studies involving 7014 patients with IMSD were included in the meta-analysis. Compared with those in the healthy control group, serum Zn levels decreased in patients with vitiligo, psoriasis, and AA; serum Cu levels increased in patients with psoriasis, AD, and AA; serum Se and Fe levels decreased in patients with psoriasis and AD.

Conclusion

Serum trace element levels showed more significant changes in patients with IMSDs than in healthy controls. These findings suggest that alterations in trace element levels may be associated with the occurrence, development, and prognosis of IMSDs.
