Over the past two decades, numerous highly effective biological treatments have been developed for patients with moderate-to-severe psoriasis. As a result of more effective therapies, treatment goals have shifted from a 50% to a 90% reduction in psoriasis area and severity index. Although randomized controlled trials provide some insight, they often include only a subset of patients, have short durations, and do not compare different treatments. Many patients respond well to these new treatments; however, some do not respond at all, whereas others experience a loss of effectiveness after an initial response. No definitive guidelines on the best time to start treatment or on how to choose the most suitable treatment for an individual patient have yet been established. Furthermore, it remains uncertain whether optimal treatment or specific therapy reduces the risk of developing comorbidities. Real-world data have revealed adverse effects, such as tuberculosis reactivation with tumor necrosis factor inhibitors, worsening of inflammatory bowel disease with interleukin-17 inhibitors, and potential cardiovascular events associated with particularly interleukin-12/23 inhibition. Studies from both clinical trials and real-world settings have also shown that patients with high body mass index, smokers, older individuals, and those with prior biological treatments tend to have poorer treatment outcomes. Recently, studies have indicated that genetic markers such as HLA-C*06:02, initial treatment response, and post-initiation drug concentration levels can predict treatment response. The integration of genetic markers, clinical data, and advanced technologies may aid in developing more personalized treatment plans for patients in the future.

Introduction: Switching biologics within or across classes can improve outcomes for patients with psoriasis who failed to meet their treatment goals on their original therapy. The objective of this study was to identify real-world baseline features which are associated with switching psoriasis therapies following sustained use of a biologic therapy.
Methods: The study was a retrospective analysis of the prospective, multicenter, non-interventional PPD™ CorEvitas™ Psoriasis Registry cohort. Patient sociodemographics, comorbidities, treatment history, disease activity, and patient-reported outcome measures were assessed at baseline visits, along with changes in disease activity and treatment at follow-up visits. Patients were classified at each follow-up visit as either switchers from one biologic therapy to another or non-switchers. Three analytic strategies-logistic regression, random forest, and decision trees-were used to identify features associated with switching.
Results: Patients contributed 14,729 follow-up visits, of which 995 episodes (6.8%) reflected a switch in biologic therapy. In logistic regression models, statistically significant associations with switching were seen for features including body surface area (BSA) involvement at baseline, change in BSA involvement from baseline to follow-up, and addition of at least one non-biologic systemic medication to treatment between baseline and follow-up. In random forest estimations, these three variables along with patient-reported fatigue and quality of life were determined to be most important. Finally, in the decision tree analysis, four subgroups of patients with moderate/severe BSA involvement at baseline in combination with other specific variables were identified as having a > 50% likelihood of switching.
Conclusion: Identification and recognition of these features and combinations thereof can facilitate shared decision-making between clinicians and patients to improve both outcomes of and patient satisfaction with biologic therapy.

Introduction: Atopic dermatitis (AD) is a chronic, relapsing inflammatory disease, significantly impacting a patient's quality of life. To date, a substantial proportion of patients present an insufficient response to available treatment options. Lebrikizumab, a monoclonal antibody targeting interleukin 13, has shown a promising clinical benefit in phase 3 trials, however, real-world data on the effectiveness and safety of lebrikizumab for atopic dermatitis (AD) are limited and mostly restricted to Asian populations. Aim of this study was to evaluate the real-world effectiveness and safety of lebrikizumab in patients with AD.
Methods: This retrospective study included 35 patients from a largely homogenous Central European population with moderate to severe Atopic Dermatitis treated with lebrikizumab at the Dermatology Department of the St. Josef-Hospital in Bochum between December 2023 and April 2025. Eczema area and severity index (EASI), SCORing Atopic Dermatitis (SCORAD), peak-pruritus (PP)-numerical rating scale (NRS) and dermatology life quality index (DLQI) were assessed during the treatment.
Results: Lebrikizumab reduced all clinical indices by week 4, with improvements maintained through week 16. At week 24, the achievement rates for EASI-50 (50% reduction in EASI), EASI-75 (75% reduction in EASI) and EASI-90 (90% reduction in EASI) were 100%, 75% and 75%, respectively, and the SCORAD-50 (50% reduction in SCORAD) response rate was 64.2%. The proportions of patients achieving a ≥ 4-point reduction in the PP-NRS and in the DLQI at week 24 were 55.8% and 91.6%, respectively. No new safety signals were observed.
Conclusion: Lebrikizumab demonstrated favorable real-world effectiveness and safety over 24 weeks in patients with moderate-to-severe AD, supporting its use in routine clinical practice.
特应性皮炎(AD)是一种慢性、复发性炎症性疾病,严重影响患者的生活质量。迄今为止,相当大比例的患者对现有的治疗方案反应不足。Lebrikizumab是一种靶向白细胞介素13的单克隆抗体,在3期试验中显示出有希望的临床益处,然而,关于Lebrikizumab治疗特应性皮炎(AD)的有效性和安全性的实际数据有限,而且主要局限于亚洲人群。本研究的目的是评估lebrikizumab在AD患者中的实际有效性和安全性。方法:这项回顾性研究包括35例来自中欧大部分同质人群的中度至重度特应性皮炎患者,这些患者于2023年12月至2025年4月在波hum St. josef医院皮肤科接受lebrikizumab治疗。评估治疗期间湿疹面积及严重程度指数(EASI)、特应性皮炎评分(SCORAD)、瘙痒峰(PP)-数值评定量表(NRS)和皮肤病生活质量指数(DLQI)。结果:Lebrikizumab在第4周降低了所有临床指标,并在第16周保持改善。在第24周,EASI-50 (EASI降低50%)、EASI-75 (EASI降低75%)和EASI-90 (EASI降低90%)的完成率分别为100%、75%和75%,SCORAD-50 (SCORAD降低50%)的有效率为64.2%。在第24周,PP-NRS和DLQI降低≥4点的患者比例分别为55.8%和91.6%。没有观察到新的安全信号。结论:Lebrikizumab在中重度AD患者24周内显示出良好的实际有效性和安全性,支持其在常规临床实践中的使用。

Introduction: Sonidegib and vismodegib are Hedgehog pathway inhibitors (HHIs) approved for the treatment of locally advanced basal cell carcinoma (laBCC), as well as metastatic basal cell carcinoma (mBCC) for vismodegib. Few studies have compared real-world treatment patterns associated with HHI treatment. The objective of this study was to investigate the real-world treatment patterns and conditions of patients receiving HHIs for BCC.
Methods: In this longitudinal study, claims from the Komodo Health Claims Database (between 2016 and 2023) were used to identify patients. Baseline characteristics and comorbidities of patients were assessed. Time to treatment discontinuation (TTD), odds of discontinuation, and clinical conditions experienced during treatment were analyzed.
Results: Patients who received sonidegib remained on treatment longer than those on vismodegib (log-rank test; P = 0.041) and were 23% less likely (P = 0.036) and 32% less likely (P = 0.013) to discontinue treatment at 6 and 9 months, respectively. Sonidegib-treated patients were less likely to experience gastrointestinal-related conditions (33% less likely; P = 0.045), taste- and smell-related conditions (71% less likely; P = 0.048), and muscle spasms (52% less likely; P = 0.009) during treatment compared with patients who received vismodegib.
Conclusion: In the real-world setting, sonidegib-treated patients remained on treatment longer than vismodegib-treated patients and were less likely to experience pharmacologically relevant clinical conditions.

Introduction: Biologic therapies have significantly improved treatment options for patients with moderate-to-severe psoriasis. Brodalumab's effectiveness, efficacy, and safety have been demonstrated in clinical trials. Real-world data are now available to confirm these outcomes in diverse populations, including those at higher risk of reduced treatment response.
Methods: This observational, prospective, multicentre study included 143 patients between 2020 and 2022. Baseline data included demographics, medical history, Psoriasis Area and Severity Index (PASI), presence of high-impact areas (HIA), Dermatology Life Quality Index (DLQI), comorbidities, and prior treatments. Follow-up visits (weeks 12-16 and 52) documented PASI, DLQI, and drug survival. The analysis focused on four potential modifiers of treatment response: body mass index (BMI), biologic treatment history, number of HIA, and age.
Results: Brodalumab demonstrated effectiveness and safety in patients with moderate-to-severe psoriasis requiring systemic therapy. Time of exposure to brodalumab was 13 months (52 weeks ± 4). At weeks 12/16, 49.6% achieved PASI 100, sustained in 61.9% at week 52. DLQI scores improved at both follow-ups, with increased proportions achieving DLQI ≤ 1. At week 52, PASI 100 and DLQI ≤ 1 were observed in 62.5% and 73.2% of patients with overweight, 48.6% and 61.8% of patients with obesity, respectively. Among older patients, 60.9% achieved PASI 100 and 65.2% reported DLQI ≤ 1. In patients with ≥ 2 HIA, 60.0% achieved PASI 100 and 68.9% experienced DLQI ≤ 1. Response was favourable across treatment history: 65.5% of bionaïve and 51.7% of bioexperienced patients achieved PASI 100; DLQI ≤ 1 was observed in 75.0% and 64.3%, respectively. Drug survival was high overall (94.6%) and across subgroups (88.3-100%). The safety profile was consistent with clinical trial data.
Conclusion: Real-world data supports brodalumab use as a valuable long-term treatment for HIA and specific subpopulations such as older, bionaïve, bioexperienced, and patients with overweight or obesity. This article is a post hoc analysis of the PSO-TARGET clinical trial (Evaluation of the Sensitivity and Specificity of a Novel Quality of Life Tool to Assess the Treatment Satisfaction in Psoriasis Patients).

Introduction: Several treatments are available for actinic keratosis (AK), many of which are hampered by local inflammation, pain, long duration, and slow healing. Indoor daylight photodynamic therapy (idl-PDT) is an effective, well-tolerated, first-line treatment for both AK and field cancerization, but its feasibility is limited by the long time required for illumination (2 h). The objective of our study was to evaluate the efficacy of idl-PDT with an illumination time of 1 h versus 2 h in the treatment of scalp AK.
Methods: We conducted an intrapatient, comparative study of idl-PDT with two illumination durations, 1 h versus 2 h, using methyl aminolevulinate (MAL, Metvix®) and a white light-emitting diode (LED) light (Dermaris®) for the treatment of scalp AK. Patients were evaluated 3 months and 6 months after one session of idl-MAL-PDT for AK response rate, both overall and by AK grade, and tolerability. Physicians' and patients' satisfaction were also investigated.
Results: A total of 55 patients were enrolled with a total of 955 AK (grade I-II). The AK clearance rate was 72.9% in 1 h-half and 71.1% in 2 h-half after 3 months, and 76.2% in 1 h-half and 78.9% in 2 h-half after 6 months. No statistically significant difference in efficacy (overall, grade I and II AK) was observed between the two illumination times, both at 3 and 6 months. The local skin reaction score and pain numeric rating scale (NRS) were very low, and comparable between the two treatment arms. Both physicians and patients expressed very good opinion on effectiveness and cosmetic outcome. Overall, 96.4% of patients would undergo idl-PDT again.
Conclusions: The efficacy of idl-PDT in treating grade I and II AK of the scalp was comparable using 1 h or 2 h as illumination time. Both treatment schedules were well tolerated, with a very high rate of satisfaction from both physicians and patients. This trial was retrospectively registered on the 4th of December 2025.

The local skin reaction score and pain numeric rating scale (NRS) were very low, and comparable between the two treatment arms. Both physicians and patients expressed very good opinion on effectiveness and cosmetic outcome. Overall, 96.4% of patients would undergo idl-PDT again.</p><p><strong>Conclusions: </strong>The efficacy of idl-PDT in treating grade I and II AK of the scalp was comparable using 1 h or 2 h as illumination time. Both treatment schedules were well tolerated, with a very high rate of satisfaction from both physicians and patients.

Introduction: Dermocosmetics are widely used to complement dermatologic care, yet context-specific guidance remains limited for populations with Fitzpatrick skin types III-V. We convened a national expert panel to generate transparent, reproducible recommendations across ten common clinical scenarios.
Methods: Egyptian dermatologists participated in round 1 (national survey, n = 601) and round 2 (expert panel, n = 16), both with anonymous ratings and inter-round feedback, using the RAND/UCLA appropriateness method (median bands 1-3/4-6/7-9; disagreement index (DI) = interpercentile range (IPR)/IPR adjusted for symmetry (IPRAS); DI > 1.0 = disagreement). Per-item outputs included median, P30, P70, IPR (30-70), asymmetry Index (AI), IPRAS, DI, and final category (appropriate/uncertain/inappropriate). We additionally benchmarked classifications against prior consensus, guidelines, and key evidence frameworks.
Results: Across ten vignettes and 30 ingredients (30 ingredients × 10 scenarios = 300 items; multiple raters per item in round 1), 158 (52.7%) items were appropriate (median ≥ 7; DI ≤ 1.0), 135 (45.0%) were uncertain, and 7 (2.3%) were inappropriate. Photoprotection had the highest appropriateness across scenarios (broad-spectrum/tinted SPF), with a small number of DI-flagged uncertain exceptions. Hydration/barrier agents (e.g., hyaluronic acid, peptides, ceramides) were appropriate in stress-aging, post-laser, and post-procedure care. Pigment modulators (tranexamic acid, arbutin, niacinamide, vitamin C, glabridin) were appropriate in melasma/post-inflammatory hyperpigmentation and chronic sun-induced pigmentation. Classical retinoids were inappropriate for postpartum/breastfeeding and immediate post-procedure; lower-irritancy retinoid esters were context-dependent. Botanicals showed inconsistent support. Panel disagreement (DI > 1.0) declined from 38.3% in round 1 to 15.7% (47/300) in round 2. Patterns largely aligned with prior consensus; visible-light-mitigating photoprotection and timing-specific retinoid use were emphasized for darker phototypes.
Conclusion: We provide a transparent, regionally relevant framework for dermocosmetic ingredient selection. Sun protection and barrier support are foundational; pigment modulators are scenario-specific; retinoids require selective use; botanicals remain adjunctive.

Port-wine stain (PWS) is a congenital capillary malformation with a 0.3-0.5% prevalence. This article reviews key techniques and advancements in the diagnosis and treatment of PWS. For assessment, several noninvasive diagnostic techniques were analyzed, including dermoscopy, high-frequency ultrasound, photoacoustic imaging, optical coherence tomography (OCT), laser speckle contrast imaging, the VISIA-CR™ system, and reflectance confocal microscopy. These methods were evaluated on the basis of factors such as vascular morphology (e.g., point, spherical, linear, grid vessels, vessel diameter, vessel wall thickness, etc.), depth of penetration, real-time blood flow monitoring, and quantitative analysis of hemoglobin. However, these noninvasive diagnostic methods share common limitations, such as restricted penetration depth, varying operator dependency, challenges in real-time quantitative analysis, and subjective interpretation in some modalities. In terms of treatment, pulsed dye laser (PDL) therapy remains the clinical gold standard for managing PWS. However, there are now additional options available, including alexandrite laser (755 nm), neodymium-doped yttrium aluminum garnet laser (1064 nm Nd:YAG), and intense pulsed light (IPL), and various other treatment strategies that cater to different characteristics of PWS. Nonetheless, efficacy can be limited by the depth of the blood vessels and individual variability. Photodynamic therapy, which targets the vascular endothelium using photosensitizers, is more effective but also more expensive. Recently, the incorporation of artificial intelligence and deep learning technology holds promise for improving the accuracy of diagnosis and personalization of PWS treatment. This represents a significant direction for future development in this field.

Introduction: Psychodermatology studies the connection between skin and mental health and is especially relevant in older adults, where visible skin changes and aging often reflect psychological well-being. This is an understudied area in dermatology.
Methods: This narrative review examined literature on the current concepts and management strategies of geriatric psychodermatology. Research databases such as MEDLINE, PubMed, Springer, Google Scholar, and others were investigated, with a total of 131 papers identified. No publication date limits were included.
Results: There is a complex and fascinating relationship between the skin and the brain often referred to as the "skin-brain axis." Common psychodermatologic disorders in the elderly include obsessive-compulsive and related disorders, delusional infestation, and psychogenic pruritus, and these are often difficult to diagnose and manage in the elderly. We also summarize secondary dermatoses from anxiety, depression, stress, and dementia in the elderly. Comprehensive geriatric assessment extends beyond physical health and includes dermatologic, psychiatric, cognitive, and psychosocial domains. Comprehensive care requires collaboration among dermatology, psychiatry, and geriatrics, often incorporating both pharmacologic and non-pharmacologic approaches. We also describe dermatologic signs of elder abuse, dementia complicating psychodermatoses, and review treatment strategies of these conditions.
Conclusion: Psychocutaneous dermatology is a relevant and understudied area that dermatologists should familiarize themselves with. Multidisciplinary care including pharmacologic and non-pharmacologic strategies are often required for the management of these patients.

Introduction: Psoriasis is a chronic inflammatory disease associated with multiple systemic comorbidities and reduced quality of life. Risankizumab, an interleukin (IL)-23 inhibitor, has demonstrated efficacy in achieving rapid and sustained skin clearance in moderate-to-severe psoriasis. However, its impact on chronic subclinical inflammation is less understood. Conventional clinical assessments like Psoriasis Area and Severity Index (PASI), Investigator's Global Assessment (IGA), and Body Surface Area (BSA) focus on evaluating visible symptoms and are limited in capturing underlying disease activity. Optical coherence tomography (OCT), a non-invasive imaging modality, offers real-time assessment of structural and vascular changes, providing valuable insights beyond the skin surface.
Methods: This sub-analysis of a prospective, single-center exploratory study included 22 patients with moderate-to-severe psoriasis treated with risankizumab. Clinical assessments (PASI, IGA, BSA) were conducted at baseline and weeks 2, 4, 16, 28, 40, and 52. OCT imaging performed at baseline and weeks 4, 16, and 52 evaluated epidermal thickness and vascular parameters (e.g., vessel density and diameter) in lesional and perilesional skin.
Results: By week 16, mean (95% confidence interval [CI]) PASI score decreased from 16.3 (11.6-21.1) at baseline to 3.5 (1.8-5.2), and BSA involvement from 24.7% (16.1-33.3) to 5.2% (1.9-8.4) (both p < 0.001). By week 52, 86.7%, 73.3%, and 40.0% of patients achieved PASI 75, 90, and 100, respectively, and 93.3% achieved IGA 0/1. OCT showed lesional reductions in epidermal thickness (- 37.4%), vessel density (- 26.6% Δ area under the curve [AUC]), and vessel diameter (- 59.5% ΔAUC) over the 52-week period. Notably, vascular changes also occurred in uninvolved perilesional skin.
Conclusion: Risankizumab improved both clinical and OCT parameters over 52 weeks, emphasizing the importance of long-term therapy with benefits extending beyond visible improvement. OCT emerged as a valuable tool for assessing deep (vascular) treatment response, thereby supporting a more comprehensive understanding of therapeutic outcomes in psoriasis.
