Abstract
BACKGROUND Interleukin-17A (IL-17A) is a proinflammatory cytokine, playing an essential role in the development of psoriasis. Although treatment with anti-IL-17A monoclonal antibodies has demonstrated high efficacy in psoriasis patients, not all patients respond equally well, highlighting the need for biomarkers to predict treatment response. Specific single nucleotide polymorphisms (SNPs) in the endoplasmatic reticulum aminopeptidase (ERAP) 1 and 2 genes have been associated with psoriasis and other immune-mediated diseases. OBJECTIVES We aimed to investigate the association between the ERAP1 and ERAP2 genotypes and response to secukinumab treatment in psoriasis patients. METHODS A total of 75 patients with plaque psoriasis were included. All patients were genotyped for the ERAP1 rs27524, rs27044, rs30187, rs2287987, and rs26653 SNPs, the ERAP2 rs2248374 SNP, and human leukocyte antigen-C*06:02 (HLA-C*06:02) status. RESULTS Our results demonstrated that individuals with specific ERAP1 and ERAP2 genotypes had a considerably lower response rate to secukinumab treatment. Patients with the ERAP2 rs2248374 G/G genotype had a more than 6-fold increased risk of treatment failure compared with patients with the rs2248374 A/G or -A/A genotypes. Stratifying for HLA-C*06:02 status, the ERAP2 G/G genotype pointed towards an increased risk of treatment failure among HLA-C*06:02-positive patients, although this was not statistically significant. CONCLUSION Taken together, this unique study breaks new ground by identifying distinct ERAP1 and ERAP2 gene variants that may serve as potential biomarkers for predicting the treatment response to secukinumab in psoriasis patients. Notable, out data extends existing knowledge by linking specific ERAP1 and ERAP2 gene variants to treatment outcome.

Abstract
ABSTRACT Patients with Sézary syndrome (SS), a leukemic variant of cutaneous T-cell lymphoma (CTCL), are prone to Staphylococcus aureus infections and have a poor prognosis due to treatment resistance. Here, we report that S aureus and staphylococcal enterotoxins (SE) induce drug resistance in malignant T cells against therapeutics commonly used in CTCL. Supernatant from patient-derived, SE-producing S aureus and recombinant SE significantly inhibit cell death induced by histone deacetylase (HDAC) inhibitor romidepsin in primary malignant T cells from patients with SS. Bacterial killing by engineered, bacteriophage-derived, S aureus-specific endolysin (XZ.700) abrogates the effect of S aureus supernatant. Similarly, mutations in major histocompatibility complex (MHC) class II binding sites of SE type A (SEA) and anti-SEA antibody block induction of resistance. Importantly, SE also triggers resistance to other HDAC inhibitors (vorinostat and resminostat) and chemotherapeutic drugs (doxorubicin and etoposide). Multimodal single-cell sequencing indicates T-cell receptor (TCR), NF-κB, and JAK/STAT signaling pathways (previously associated with drug resistance) as putative mediators of SE-induced drug resistance. In support, inhibition of TCR-signaling and Protein kinase C (upstream of NF-κB) counteracts SE-induced rescue from drug-induced cell death. Inversely, SE cannot rescue from cell death induced by the proteasome/NF-κB inhibitor bortezomib. Inhibition of JAK/STAT only blocks rescue in patients whose malignant T-cell survival is dependent on SE-induced cytokines, suggesting 2 distinct ways SE can induce drug resistance. In conclusion, we show that S aureus enterotoxins induce drug resistance in primary malignant T cells. These findings suggest that S aureus enterotoxins cause clinical treatment resistance in patients with SS, and antibacterial measures may improve the outcome of cancer-directed therapy in patients harboring S aureus.

Abstract
INTRODUCTION Alopecia areata (AA) is an autoimmune skin disease presenting as nonscarring hair loss. Information on the epidemiology of AA, especially the occurrence of AA and its subtypes within the general population, is scarce. The study aimed to estimate the incidence rates and prevalence of hospital-treated AA and its subtypes in Denmark and to examine the demographic and clinical characteristics of patients with AA, including comorbidities and use of prescription medications. METHODS This was a cohort study based on data from administrative and health registers in Denmark in 1995-2016. The study included individuals who were (1) registered with a hospital inpatient or hospital-based outpatient clinic diagnosis of AA between 1995 and 2016 in the Danish National Patient Registry covering encounters at all Danish hospitals, (2) alive and resided in Denmark anytime between 1995 and 2016, (3) aged ≥ 12 years, and (4) resided uninterrupted in Denmark during the 12 months before the first AA diagnosis during the study period. RESULTS During the study period, 2778 individuals with an incident hospital-based diagnosis of AA were identified; 63.1% were female and 28.7% of the patients were aged ≥ 50 years. Over the study period, the overall incidence rate for any hospital-treated AA per 100,000 person-years was 2.62 (95% confidence interval [CI], 2.53-2.72), and the overall prevalence in 2016 was 71.7 (95% CI 69.4-74.1) per 100,000 persons. Both incidence rate and prevalence increased over time. Prevalence of most hospital-treated comorbidities or history of medication use was below 10% and was similar in the alopecia totalis (AT)/alopecia universalis (AU) and non-AT/AU subtypes of AA. CONCLUSION This cohort study reported incidence rates and prevalence over time and characteristics of individuals with hospital-treated AA in Denmark, which are in agreement with those previously reported in this population.

Abstract
Psoriatic arthritis mutilans (PAM) is the rarest and most severe form of psoriatic arthritis, characterized by erosions of the small joints and osteolysis leading to joint disruption. Despite its severity, the underlying mechanisms are unknown, and no susceptibility genes have hitherto been identified. We aimed to investigate the genetic basis of PAM by performing massive parallel sequencing in sixty-one patients from the PAM Nordic cohort. We found rare variants in the NADPH oxidase 4 (NOX4) in four patients. In silico predictions show that the identified variants are potentially damaging. NOXs are the only enzymes producing reactive oxygen species (ROS). NOX4 is specifically involved in the differentiation of osteoclasts, the cells implicated in bone resorption. Functional follow-up studies using cell culture, zebrafish models, and measurement of ROS in patients uncovered that these NOX4 variants increase ROS levels both in vitro and in vivo. We propose NOX4 as the first candidate susceptibility gene for PAM. Our study links high levels of ROS caused by NOX4 variants to the development of PAM, offering a potential therapeutic target.

Abstract
Background Heat shock protein 90 (HSP90) is an important chaperone supporting the function of many proinflammatory client proteins. Recent studies indicate HSP90 inhibition may be a novel mechanism of action for inflammatory skin diseases; however, this has not been explored in atopic dermatitis (AD). Objectives Our study aimed to investigate HSP90 as a novel target to treat AD. Methods Experimental models of AD were used including primary human keratinocytes stimulated with cytokines (TNF/IFNγ or TNF/IL-4) and a mouse model established by MC903 applications. Results In primary human keratinocytes using RT-qPCR, the HSP90 inhibitor RGRN-305 strongly suppressed the gene expression of Th1- (TNF, IL1B, IL6) and Th2-associated (CCL17, CCL22, TSLP) cytokines and chemokines related to AD. We next demonstrated that topical and oral RGRN-305 robustly suppressed MC903-induced AD-like inflammation in mice by reducing clinical signs of dermatitis (oedema and erythema) and immune cell infiltration into the skin (T cells, neutrophils, mast cells). Interestingly, topical RGRN-305 exhibited similar or slightly inferior efficacy but less weight loss compared with topical dexamethasone. Furthermore, RNA sequencing of skin biopsies revealed that RGRN-305 attenuated MC903-induced transcriptome alterations, suppressing genes implicated in inflammation including AD-associated cytokines (Il1b, Il4, Il6, Il13), which was confirmed by RT-qPCR. Lastly, we discovered using Western blot that RGRN-305 disrupted JAK-STAT signaling by suppressing the activity of STAT3 and STAT6 in primary human keratinocytes, which was consistent with enrichment analyses from the mouse model. Conclusion HSP90 inhibition by RGRN-305 robustly suppressed inflammation in experimental models mimicking AD, proving that HSP90 inhibition may be a novel mechanism of action in treating AD.

Abstract
Importance Hidradenitis suppurativa is a painful immune-mediated disorder with limited treatment options; hence, a need exists for new treatments. Objective To evaluate the feasibility of heat shock protein 90 inhibition by RGRN-305 as a novel mechanism of action in treating moderate to severe hidradenitis suppurativa. Design, Setting, and Participants This was a parallel-design, double-blind, proof-of-concept, placebo-controlled randomized clinical trial conducted between September 22, 2021, and August 29, 2022, at the Department of Dermatology, Aarhus University Hospital in Denmark. The study included a 1- to 30-day screening period, a 16-week treatment period, and a 4-week follow-up period. Eligibility criteria included age 18 years or older and moderate to severe hidradenitis suppurativa with 6 or more inflammatory nodules or abscesses in at least 2 distinct anatomic regions. Of 19 patients screened, 15 patients were enrolled in the study. Intention-to-treat analysis was performed. Interventions Patients were randomly assigned (2:1) to receive oral RGRN-305, 250-mg tablet, or matching placebo once daily for 16 weeks. Main Outcomes and Measures The primary efficacy end point was the percentage of patients achieving Hidradenitis Suppurativa Clinical Response 50 (HiSCR-50) at week 16. Secondary efficacy end points included HiSCR-75 or HiSCR-90, Hidradenitis Suppurativa Physician's Global Assessment, Dermatology Life Quality Index scores, and a pain numeric rating scale. Safety was assessed by adverse events, physical examinations, clinical laboratory measurements, and electrocardiograms. Results A total of 15 patients were enrolled, completed the study, and were included in all analyses (10 [67%] female; median age, 29 [IQR, 23-41] years). The primary end point HiSCR-50 at week 16 was achieved by a higher percentage in the RGRN-305 group (60% [6 of 10]) than in the placebo group (20% [1 of 5]). Improvements were also observed across all secondary end points at week 16, including higher rates of the harder-to-reach HiSCR levels; 50% (5 of 10) achieved HiSCR-75 and 30% (3 of 10) achieved HiSCR-90, whereas none of the placebo-treated patients achieved HiSCR-75 or HiSCR-90. RGRN-305 was well tolerated, with no deaths or serious adverse events, and treatment-emergent adverse events were similarly frequent between the RGRN-305 and placebo groups. Conclusions and Relevance The findings of this trial suggest that heat shock protein 90 inhibition by RGRN-305 offers a novel mechanism of action in treating hidradenitis suppurativa, warranting further evaluation in larger trials. Trial Registration ClinicalTrials.gov Identifier: NCT05286567.

Abstract
BACKGROUND Clinical trials have shown promising results for interleukin-23 inhibitors in the treatment of psoriasis. The drugs have been used in clinical practice since 2017. OBJECTIVE To investigate the drug survival and effectiveness of interleukin-23 inhibitors in the treatment of psoriasis and psoriatic arthritis (PsA) in a real-world setting. METHODS The study was a retrospective analysis of patients treated with either guselkumab, tildrakizumab, or risankizumab at the Department of Dermatology, Aarhus University Hospital, during the period from June 11 2018, to July 14 2021. RESULTS A total of 80 patients were included. During the study, 19 patients discontinued treatment with an interleukin-23 inhibitor, and mean treatment duration (SD) was 61.4 weeks (43.7). Seventy-six patients (95%) had previous use of ≥1 biologic. One-year drug survival was 81.0%. Among patients, 64.3% achieved a Psoriasis Area and Severity Index (PASI) ≤ 2 at weeks 12-17; 61.3%, at weeks 40-60. There was no statistically significant difference between the drugs regarding the chance of achieving PASI ≤ 2 (p>.05). Twenty-two patients (27.5%) had PsA. Among these, 40.9% and 36.4% achieved complete remission and partial remission, respectively. CONCLUSIONS Interleukin-23 inhibitors appear to have high and similar drug survival and effectiveness in patients with difficult-to-treat psoriasis and PsA.

Abstract
Hidradenitis suppurativa is a chronic inflammatory skin disease with limited treatment options. The poorly understood pathogenesis hinders the development of effective treatments; therefore, a pressing need exists to further elucidate the molecular mechanisms in hidradenitis suppurativa. This study investigated the underlying inflammatory pathways and cell types in hidradenitis suppurativa using transcriptomic approaches with RNA sequencing of lesional and non-lesional skin biopsies from hidradenitis suppurativa, which was jointly analyzed with previously published transcriptomic data from atopic dermatitis and psoriasis patients. The differential expression and pathway enrichment analyses demonstrated the activation of multiple inflammatory processes, including the innate and adaptive immune systems, implicated in the hidradenitis suppurativa pathogenesis. In agreement, hidradenitis suppurativa exhibited a unique and heterogeneous cell type signature involving lymphoid and myeloid cells such as B cells and macrophages. Furthermore, hidradenitis suppurativa displayed increased expression of TH1/2/17 signatures with no predominant TH signatures unlike psoriasis (TH1/17) and atopic dermatitis (TH2). In summary, our study provides molecular insights into the pathomechanisms in hidradenitis suppurativa, revealing a strong and widespread immune activation, which may benefit from treatment strategies offering a broad immunomodulation of various key inflammatory pathways. Our data not only corroborate previously reported findings but also enhance our understanding of the immune dysregulation in hidradenitis suppurativa, uncovering novel and potential therapeutic targets.

Abstract
Progressive myelopathy, urinary retention and gait problems are rare presenting features of Lyme neuroborreliosis. A 30-year-old man had 11 months of urinary retention and 3 months of spastic paraparesis. MR scans of the brain and the spinal cord showed leptomeningeal thickening with contrast enhancement. Cerebrospinal fluid showed mononuclear pleocytosis, decreased glucose, increased protein and chemokine ligand 13, with intrathecal Borrelia-specific IgM and IgG antibodies. He received 14 days of intravenous ceftriaxone followed by 14 days of oral doxycycline. Despite improvement at 6 months, he still had severe gait problems. Urinary retention in otherwise healthy people needs investigation, and Lyme neuroborreliosis is a rare cause.

Abstract
BACKGROUND The fixed dose combination of calcipotriene (CAL) and betamethasone dipropionate (BDP) is a well-established topical treatment option for psoriasis based on strong scientific rationale for the single agents having complementary efficacy and safety. CAL/BDP PAD-cream is an easily spreadable cream based on PAD Technology™, an innovative formulation and drug delivery system. OBJECTIVES AND METHODS A Phase 3, multicentre, randomized, investigator-blind, active and vehicle-controlled trial enrolling 490 patients with mild to moderate psoriasis according to the Physician Global Assessment (PGA) scale was conducted in three European countries. Products were applied once daily for 8 weeks. The aim of the trial was to evaluate the efficacy and safety of CAL/BDP PAD-cream as well as treatment acceptability compared to CAL/BDP gel and PAD-cream vehicle. Primary endpoint was percentage change in modified Psoriasis Area and Severity Index (mPASI) from baseline to Week 8. RESULTS The percentage mean change from baseline to Week 8 in mPASI for CAL/BDP PAD-cream (67.5%) was superior compared to PAD-cream vehicle (11.7%; p < 0.0001) and non-inferior to CAL/BDP gel (63.5%). The proportion of patients achieving PGA treatment success (at least two-step improvement to clear or almost clear) after 8 weeks was superior for CAL/BDP PAD-cream (50.7%) compared to PAD-cream vehicle (6.1%, p < 0.0001) and statistically significantly greater than CAL/BDP gel (42.7%, p = 0.0442). Patient-reported psoriasis treatment convenience score (PTCS) for CAL/BDP PAD-cream was rated superior to CAL/BDP gel at Week 8 (p < 0.0001) and the mean change in DLQI from baseline to Week 8 improved statistically significantly more in the CAL/BDP PAD-cream group compared to both PAD-cream vehicle (p < 0.0001) and CAL/BDP gel (p = 0.0110). Safety assessments during the trial demonstrated that CAL/BDP PAD-cream was well-tolerated. CONCLUSION CAL/BDP PAD-cream is a novel topical treatment of psoriasis that has a high efficacy and a favourable safety profile combined with a superior patient-reported treatment convenience.

Abstract
BACKGROUND Secukinumab is effective against a range of psoriatic manifestations. Investigating psoriasis (PsO) relapse following secukinumab discontinuation could provide insights into long-term PsO remission. OBJECTIVE To examine PsO relapse rates upon treatment discontinuation following one year of secukinumab treatment. METHODS This study (NCT01544595) is an extension of the Phase 3 ERASURE/FIXTURE studies in patients with moderate-to-severe plaque PsO. After one year of secukinumab 300 mg or 150 mg treatment, Week 52 PASI75 responders were randomly assigned to receive placebo. Upon relapse, patients receiving placebo were switched to their previous secukinumab dose. The study primary outcome was non-relapse rate after secukinumab withdrawal. RESULTS Following the last dose of secukinumab 300 mg, 21% and 10% of patients who switched to placebo did not relapse at one and two years after discontinuation, respectively. Patients who received secukinumab 150 mg for one year showed a lower proportion of non-relapse following treatment discontinuation (14% and 6%) at one and two years, respectively). Non-relapsing patients maintained low mean PASI (2.8) at one year drug-free versus baseline (20.9); 1.7 at two years drug-free versus baseline (19.2). Disease duration (P=0.017) and severity (P=0.022) were significantly associated with time-to-relapse in patients initially treated with secukinumab 300 mg; patients with shorter disease duration and lower baseline PASI remained relapse-free for longer. CONCLUSIONS Following discontinuation of secukinumab, a proportion of patients stayed relapse-free. Further, patients with shorter disease duration remained relapse-free for longer, suggesting that earlier treatment with secukinumab may result in long-term clinical control of moderate-to-severe PsO.

Abstract
Topical treatment plays a crucial role in psoriasis management, with non-adherence being a major barrier to treatment success. The fixed-dose combination of calcipotriol (CAL) and betamethasone dipropionate (BDP) represents the first-line choice in topical psoriasis treatment. A CAL/BDP cream based on polyaphron dispersion (PAD) Technology has emerged as a novel formulation for a more convenient topical treatment of psoriasis. This article aims to summarize the most relevant published evidence about CAL/BDP PAD-cream and its underlying PAD Technology. The PAD Technology enables CAL and BDP stability in an aqueous cream through a multimolecular shell structure, as well as it increases the penetration of both active ingredients into the epidermis and dermis. This technology also demonstrated to increase the cosmetic acceptability and to provide the desirable sensory properties for a topical psoriasis treatment. Two phase III clinical trials have been conducted so far with CAL/BDP PAD-cream. Findings from both trials revealed high efficacy with a fast onset of action, a favourable safety and tolerability profile and convenience for CAL/BDP PAD-cream compared to CAL/BDP gel. In the trial including patients with psoriasis affecting the scalp (MC2-01-C7), results support the use of CAL/BDP PAD-cream in scalp psoriasis. An anchored matching-adjusted indirect comparison (MAIC) was conducted to compare CAL/BDP PAD-cream and CAL/BDP foam, as both products had been previously compared to CAL/BDP gel. CAL/BDP PAD-cream and CAL/BDP foam showed equivalent efficacy and quality of life at their recommended treatment duration, whereas greater treatment satisfaction for CAL/BDP PAD-cream was found after one week of treatment. Overall, the high patient acceptability and treatment satisfaction observed with CAL/BDP PAD-cream in clinical trials may lead to improved adherence and hence higher efficacy in clinical practice.

Abstract
Staphylococcus aureus is suspected to fuel disease activity in cutaneous T-cell lymphomas. In this study, we investigate the effect of a recombinant, antibacterial protein, endolysin (XZ.700), on S. aureus skin colonization and malignant T-cell activation. We show that endolysin strongly inhibits the proliferation of S. aureus isolated from cutaneous T-cell lymphoma skin and significantly decreases S. aureus bacterial cell counts in a dose-dependent manner. Likewise, ex vivo colonization of both healthy and lesional skin by S. aureus is profoundly inhibited by endolysin. Moreover, endolysin inhibits the patient-derived S. aureus induction of IFNγ and the IFNγ-inducible chemokine CXCL10 in healthy skin. Whereas patient-derived S. aureus stimulates activation and proliferation of malignant T cells in vitro through an indirect mechanism involving nonmalignant T cells, endolysin strongly inhibits the effects of S. aureus on activation (reduced CD25 and signal transducer and activator of transcription 5 phosphorylation) and proliferation (reduced Ki-67) of malignant T cells and cell lines in the presence of nonmalignant T cells. Taken together, we provide evidence that endolysin XZ.700 inhibits skin colonization, chemokine expression, and proliferation of pathogenic S. aureus and blocks their potential tumor-promoting effects on malignant T cells.

Abstract
INTRODUCTION Psoriasis ranges from mild to severe with the majority of patients having mild disease. Mild to moderate disease is often treated with topical therapies while photo-, oral, and biologic therapies are generally reserved for moderate-to-severe disease. There is a strong scientific rationale for the combination of calcipotriene (CAL) and betamethasone dipropionate (BDP) with respect to mode of action, efficacy, and safety and CAL/BDP has shown an inhibitory effect on key pathogenic cytokines in psoriasis including tumor necrosis factor-α, interleukin (IL)-17, and IL-23. METHODS The objective of this pooled post hoc analysis is to investigate the efficacy of CAL/BDP polyaphron dispersion (PAD)-cream in subgroups of patients with moderate-to-severe psoriasis from two completed phase 3 studies conducted in the USA and Europe. RESULTS The proportion of patients achieving Physician Global Assessment (PGA) treatment success as well as a modified Psoriasis Area and Severity Index (mPASI)75 response was higher in the subgroup with a body surface area > 10% and mPASI > 10 and Dermatology Life Quality Index > 10 at baseline compared to the overall patient population. Furthermore, the numerical difference in treatment efficacy between CAL/BDP PAD-cream and CAL/BDP topical suspension/gel increased in patient subgroups with higher baseline severity. Similar patterns were shown for the patient-reported outcomes. CONCLUSION In this subgroup analysis, patients who had higher disease severity at baseline achieved greater efficacy than the total patient population when treated with 8 weeks of CAL/BDP PAD-cream as compared to a currently marketed active comparator. Additionally, as indicated by this analysis, CAL/BDP PAD-cream treatment may also be more convenient and less greasy, which may reduce the burden of daily treatment and improve adherence to therapy.

Abstract
Enhanced treatment options for psoriasis and growing use of guidelines increased the potential to better quality of psoriasis care in Europe. The aim of the PsoBarrier EU study is to compare the quality and processes of psoriasis care in four European countries with different healthcare systems, based on validated quality indicators. This cross-sectional survey was conducted in dermatology centres in Denmark, Germany, Poland and Spain on 1,304 patients, using standardized patient and physician questionnaires. Measured by quality of psoriasis care indicators, patients in Poland had the most critical outcomes, such as the highest disease severity (Psoriasis Area and Severity Index; PASI) and lowest health-related quality of life (Dermatology Life Quality Index; DLQI). This indicates differences in psoriasis care, with Polish participants experiencing more severe psoriasis and its consequences. Differences in the healthcare systems, which create barriers to accessing treatments, could explain variations in quality of care.

Abstract
INTRODUCTION The purpose of this study is to explore treatment preferences and identify patient characteristics in young bio-naive adults with moderate to severe psoriasis in the Nordic countries (Norway, Finland, Sweden, and Denmark). METHODS Patients were 18-45 years old and bio-naive but referred for biologic treatment of moderate to severe psoriasis. Patients were included at eight Nordic dermatology clinics. Patients with significant comorbidity or psoriatic arthritis were excluded. The Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) were assessed along with basic patient information. A semistructured interview guide was used in individual qualitative interviews, asking patients about their treatment preferences and reasons, disease journey, and disease management. The interviews were analyzed using thematic content analysis. Twenty-four patients sufficed to reach saturation in this qualitative study. RESULTS The patient sample characteristics represented a qualitative variation in age, sex, symptoms, duration of disease, and country. We included a total of 12 male and 12 female patients. The mean age was 34 years (range 18-45 years), the mean age at diagnosis was 20 years (range 6-34 years), the mean ± standard deviation (SD) time since diagnosis was 13 ± 8 years, PASI was 9.5 ± 4.7, and DLQI was 15.2 ± 6.4. Interviews suggested that both the burden of disease as well as the burden of treatment influenced patient preferences regarding treatment attributes, hence getting alleviation from symptoms did not alone influence patient preferences. Time, effort, and inconvenience related to psoriasis treatments also influenced patient preferences. CONCLUSIONS This first in-depth, qualitative study in young bio-naive adults with psoriasis suggests that patient preferences are focusing not only on symptom relief but also on alleviating the burden of psoriasis treatment. Understanding the reasons for patient preferences and the perspectives of young adults is needed to guide individual shared decision-making in psoriasis management.

Abstract
Background Roflumilast is a targeted inhibitor of phosphodiesterase (PDE)-4 and has been approved for treatment of severe chronic obstructive pulmonary disease for more than a decade. Generic versions are available in the United States. PDE-4 is involved in the psoriasis pathogenesis, but the efficacy and safety of oral roflumilast in patients with psoriasis have not previously been studied. Methods A company-independent, multicenter, randomized, double-blind, placebo-controlled trial (ClinicalTrials.govNCT04549870). Patients were randomized 1:1 to receive monotherapy with oral roflumilast 500 μg once daily or placebo. At week 12, placebo patients were switched to open-label roflumilast through week 24. The primary endpoint was a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI75) at week 12. Findings In all, 46 patients were randomized (roflumilast, n = 23; placebo, n = 23). At week 12, significantly more patients in the active arm achieved PASI75 (8 of 23 patients [35%]) vs. placebo (0 of 23 patients [0%], with a difference vs. placebo of 8 [35%] patients, 95% CI: 3 [13%]-13 [57%] patients) (p = 0.014). At week 24, 15 (65%), 10 (44%), 5 (22%), and 2 (9%) of patients treated with roflumilast from week 0 had PASI50, PASI75, PASI90, and PASI100 responses (key secondary endpoints), respectively. The most prevalent, drug-related adverse events in both treatment groups were transient gastrointestinal symptoms, weight-loss, headache, and insomnia. A total of three patients (roflumilast n = 2; placebo, n = 1) discontinued therapy due to adverse events. Interpretation Oral roflumilast was efficacious and safe in treating moderate-to-severe plaque psoriasis over 24 weeks. With generic versions available, this drug may represent an inexpensive and convenient alternative to established systemic psoriasis treatments. Funding Financial support was received from Herlev and Gentofte Hospital, University of Copenhagen, and independent grants from private foundations in Denmark. No pharmaceutical company, including the market authorization holder of roflumilast, was involved in the study at any point.

Abstract
BACKGROUND Clinical trials have established the efficacy of brodalumab in treatment of psoriasis and psoriatic arthritis. Real-world evidence is needed to fully evaluate the drug. OBJECTIVE Here we investigate drug survival and clinical effectiveness of brodalumab in patients with psoriasis and psoriatic arthritis in a real-world setting. METHODS This was a retrospective single-centre study enrolling patients receiving brodalumab for psoriasis at the Department of Dermatology, Aarhus University Hospital, Denmark. The primary endpoints were drug survival, reasons for discontinuation, percentage of patients achieving a Psoriasis Area and Severity Index (PASI) ≤ 2 and clinical effectiveness against psoriatic arthritis. RESULTS Eighty-three patients were included (mean age 49.2 ± 17.4 years, 59.0% male, 9.6% bio-naïve, mean baseline PASI 10.9 ± 6.9). Twenty-seven patients discontinued treatment primarily due to ineffectiveness and adverse events (AEs). Kaplan-Meier-estimated 1-year drug survival was 65.7%. An absolute Psoriasis Area and Severity Index (PASI) ≤ 2 was achieved by 68.2% of patients at end of follow-up, by 70.0% at weeks 12-17 and by 76.2% after 40-60 weeks of treatment. Neither drug survival nor PASI ≤ 2 was associated with baseline PASI ≥ 10, body mass index ≥ 30, previous treatment with > 2 biologics or other IL-17 inhibitors in particular (P > 0.05). Psoriatic arthritis remission or partial remission was achieved by 10 out of 18 patients with psoriatic arthritis; treatment failure was reported in 5 patients. CONCLUSIONS Brodalumab was effective against psoriasis and psoriatic arthritis in a real-world setting. The drug survival was lower than reported in other real-world settings.

Abstract
The p90 ribosomal S6 kinases (RSKs) contain two distinct catalytic kinase domains, the N-terminal and C-terminal kinase domains (NTKD and CTKD, respectively). The activation of CTKD is regulated by phosphorylation by extracellular signal-regulated kinase (ERK1/2) and an autoinhibitory αL helix. Through a mutational series in vitro of the RSK CTKDs, we found a complex mechanism lifting autoinhibition that led us to design constitutively active RSK CTKDs. These are based on a phosphomimetic mutation and a C-terminal truncation (e.g., RSK2 T577E D694*) where a high activity in absence of ERK phosphorylation is obtained. Using these constructs, we characterize IC50 values of ATP-competitive inhibitors and provide a setup for determining specificity constants (kinact/Ki) of covalent CTKD inhibitors.

Abstract
The function of most lipases is controlled by the lid, which undergoes conformational changes at a water–lipid interface to expose the active site, thus activating catalysis. Understanding how lid mutations affect lipases’ function is important for designing improved variants. Lipases’ function has been found to correlate with their diffusion on the substrate surface. Here, we used single-particle tracking (SPT), a powerful tool for deciphering enzymes’ diffusional behavior, to study Thermomyces lanuginosus lipase (TLL) variants with different lid structures in a laundry-like application condition. Thousands of parallelized recorded trajectories and hidden Markov modeling (HMM) analysis allowed us to extract three interconverting diffusional states and quantify their abundance, microscopic transition rates, and the energy barriers for sampling them. Combining those findings with ensemble measurements, we determined that the overall activity variation in the application condition is dependent on surface binding and lipase mobility when bound. Specifically, the L4 variant with a TLL-like lid and wild-type (WT) TLL displayed similar ensemble activity, but WT bound stronger to the surface than L4, while L4 had a higher diffusion coefficient and thus activity when bound to the surface. These mechanistic elements can only be de-convoluted by our combined assays. Our findings offer fresh perspectives on the development of the next iteration of enzyme-based detergent.

Abstract
Background In psoriasis, poor treatment adherence is frequently related to low efficacy and limited cosmetic acceptability from the patients' perspective. This study aimed to characterize the sensorial attributes of a calcipotriol (CAL) and betamethasone dipropionate (BDP)-cream vehicle based on polyaphron dispersion (PAD) Technology and to compare them with the conventional ointment and oleogel formulations for psoriasis. Methods A panel of 16 experts assessed sensory properties at four different stages: appearance, pick up, rub out and afterfeel. Descriptive sensory analysis was used to evaluate relevant attributes. Each attribute was rated on a line scale (range 0-100%). Active ingredients were not used because panellists were healthy volunteers, and vehicle formulations needed to be used instead. Results CAL/BDP PAD-cream vehicle was evaluated as having a low stickiness, low grease behaviour, good wetness, and good spreadability. Ointment showed the least desirable behaviour regarding these properties. Moreover, once CAL/BDP PAD-cream vehicle was absorbed, the gloss disappeared quickly, leaving low stickiness and a low amount of residue. This afterfeel behaviour was not observed with ointment. The oleogel formulation had good sensory properties, similar to CAL/BDP PAD-cream vehicle, but with lower integrity of shape, lower wetness and higher greasiness. Conclusion Overall, CAL/BDP PAD-cream vehicle has the desirable requirements for a topical product for the treatment of psoriasis, with better sensory properties than ointment and easier manipulation than oleogel, which may lead to greater acceptance and adherence.

Abstract
BACKGROUND Psoriatic arthritis (PsA) is a chronic inflammatory arthritis that occurs in a large proportion of patients with psoriasis causing pain and impaired quality of life. Early recognition and treatment are important as PsA may result in structural joint damage with a risk of reduced physical function. OBJECTIVES The aim of this study was to determine the proportion of psoriasis patients with suspicion of PsA who are diagnosed with PsA or other rheumatologic conditions following referral from a dermatology department. Furthermore, the study aimed to identify clinical and patient-reported variables identifying patients with psoriasis in whom joint discomfort is an expression of PsA. METHODS This single-center retrospective study included all patients with psoriasis who had been referred for rheumatological evaluation on suspicion of PsA in the period from 2014 to 2018. RESULTS A total of 364 patient records were reviewed. This identified 106 patients with psoriasis who had been referred for rheumatologic evaluation on suspicion of PsA. Patients with a previous diagnosis of PsA were excluded from the analysis. Among the referred patients, 23.6% were diagnosed with either peripheral or axial PsA, or both. A total of 23.6% were diagnosed with osteoarthritis and an additional 14.2% were diagnosed with inactive PsA. For patient-reported swollen joints and dermatologist-assessed swollen joints at referral, the positive predictive values/negative predictive values for a PsA diagnosis were 40%/100% and 50%/92%, respectively. Conclusion: In this study, 23.6% of patients with psoriasis with symptoms suggestive of PsA were diagnosed with axial and/or peripheral arthritis following rheumatologic evaluation. Patient-reported swollen joints and dermatologist-assessed swollen joints indicated a high likelihood of peripheral PsA. Additionally, the absence of patient-reported swollen joints indicated a very low probability of establishing a diagnosis of peripheral PsA.

Abstract
Introduction Chronic inflammatory skin diseases may have a profound negative impact on the quality of life. Current treatment options may be inadequate, offering an unsatisfactory response or side effects. Therefore, ongoing efforts exist to identify novel effective and safe treatments. Heat shock protein (HSP) 90 is a chaperone that promotes the activity of a wide range of client proteins including key proinflammatory molecules involved in aberrant inflammation. Recently, a proof-of-concept clinical trial of 13 patients suggested that RGRN-305 (an HSP90 inhibitor) may be an oral treatment for psoriasis. However, HSP90 inhibition may be a novel therapeutic approach extending beyond psoriasis to include multiple immune-mediated inflammatory skin diseases. Methods This study aimed to investigate (i) the anti-inflammatory effects and mechanisms of HSP90 inhibition and (ii) the feasibility of topical RGRN-305 administration (new route of administration) in models of inflammation elicited by 12-O-tetradecanoylphorbol-13-acetate (TPA) in primary human keratinocytes and mice (irritative dermatitis murine model). Results/Discussion In primary human keratinocytes stimulated with TPA, a Nanostring® nCounter gene expression assay demonstrated that HSP90 inhibition with RGRN-305 suppressed many proinflammatory genes. Furthermore, when measured by quantitative real-time polymerase chain reaction (RT-qPCR), RGRN-305 significantly reduced the gene expression of TNF, IL1B, IL6 and CXCL8. We next demonstrated that topical RGRN-305 application significantly ameliorated TPA-induced skin inflammation in mice. The increase in ear thickness (a marker of inflammation) was significantly reduced (up to 89% inhibition). In accordance, RT-qPCR of the ear tissue demonstrated that RGRN-305 robustly reduced the gene expression of proinflammatory markers (Tnf, Il1b, Il6, Il17A and Defb4). Moreover, RNA sequencing revealed that RGRN-305 mitigated TPA-induced alterations in gene expression and suppressed genes implicated in inflammation. Lastly, we discovered that the anti-inflammatory effects were mediated, at least partly, by suppressing the activity of NF-κB, ERK1/2, p38 MAPK and c-Jun signaling pathways, which are consistent with previous findings in other experimental models beyond skin inflammation. In summary, HSP90 inhibition robustly suppressed TPA-induced inflammation by targeting key proinflammatory cytokines and signaling pathways. Our findings suggest that HSP90 inhibition may be a novel mechanism of action for treating immune-mediated skin disease beyond psoriasis, and it may be a topical treatment option.

Abstract
BACKGROUND Biologic treatments have been studied mainly in patients with a long-term history of psoriasis and previous treatment failures. OBJECTIVES The purpose of this primary analysis of the STEPIn study is to determine whether early intervention with secukinumab in patients with new-onset moderate to severe plaque psoriasis is superior to standard of care treatment with narrow band ultraviolet B (nb-UVB) phototherapy. METHODS The STEPIn study is a randomized, open-label, multicentre study to investigate early intervention with 52 weeks of secukinumab 300 mg administered subcutaneously versus standard treatment with nb-UVB phototherapy in patients with new-onset (≤12 months) moderate to severe plaque psoriasis (NCT03020199). The primary and additional secondary endpoints were ≥90% improvement in Psoriasis Area and Severity Index (PASI 90) at Week 52 and Investigator's Global Assessment (IGA mod 2011) 0/1 response at Week 52, respectively. RESULTS In the secukinumab and nb-UVB study arms, 77/80 and 76/80 randomized patients received at least one dose of study treatment, respectively. The primary endpoint was achieved: 91.1% (70/77) of patients achieved a PASI 90 response at Week 52 in the secukinumab arm versus 42.3% (32/76) in the nb-UVB arm (p < 0.0001, odds ratio [OR] estimate [95% confidence intervals, CI] = 16.3 [5.6, 46.9]). The additional secondary endpoint was also achieved: 85.7% of patients achieved an IGA 0/1 response at Week 52 in the secukinumab arm versus 36.8% in the nb-UVB arm (p < 0.0001). The safety data were consistent with the safety profiles of secukinumab and nb-UVB with no new or unexpected safety signals. CONCLUSIONS Secukinumab was superior to nb-UVB in treating patients with new-onset moderate to severe plaque psoriasis. The high and sustained skin clearance observed indicates that biologic treatment for psoriasis may be more effective if used early in the disease course.

Abstract
Immune mediated inflammatory diseases (IMIDs) are a heterogeneous group of debilitating, multifactorial and unrelated conditions featured by a dysregulated immune response leading to destructive chronic inflammation. The immune dysregulation can affect various organ systems: gut (e.g., inflammatory bowel disease), joints (e.g., rheumatoid arthritis), skin (e.g., psoriasis, atopic dermatitis), resulting in significant morbidity, reduced quality of life, increased risk for comorbidities, and premature death. As there are no reliable disease progression and therapy response biomarkers currently available, it is very hard to predict how the disease will develop and which treatments will be effective in a given patient. In addition, a considerable proportion of patients do not respond sufficiently to the treatment. ImmUniverse is a large collaborative consortium of 27 partners funded by the Innovative Medicine Initiative (IMI), which is sponsored by the European Union (Horizon 2020) and in-kind contributions of participating pharmaceutical companies within the European Federation of Pharmaceutical Industries and Associations (EFPIA). ImmUniverse aims to advance our understanding of the molecular mechanisms underlying two immune-mediated diseases, ulcerative colitis (UC) and atopic dermatitis (AD), by pursuing an integrative multi-omics approach. As a consequence of the heterogeneity among IMIDs patients, a comprehensive, evidence-based identification of novel biomarkers is necessary to enable appropriate patient stratification that would account for the inter-individual differences in disease severity, drug efficacy, side effects or prognosis. This would guide clinicians in the management of patients and represent a major step towards personalized medicine. ImmUniverse will combine the existing and novel advanced technologies, including multi-omics, to characterize both the tissue microenvironment and blood. This comprehensive, systems biology-oriented approach will allow for identification and validation of tissue and circulating biomarker signatures as well as mechanistic principles, which will provide information about disease severity and future disease progression. This truly makes the ImmUniverse Consortium an unparalleled approach.

Abstract
Psoriasis is a common chronic inflammatory skin disease accompanied by heterogenous clinical and histological features, including a characteristic keratinocyte hyperproliferation and dermal immunogenic profile. In addition, psoriasis is associated with widespread transcriptomic alterations including changes in microRNA (miRNA) and circular RNA (circRNA) abundance, which constitute non-coding RNA (ncRNA) classes with specific regulatory capacities in diverse physiological and pathological processes. However, the knowledge about the expression dynamics of ncRNA during psoriasis treatment is sparse. To elucidate the dynamics of miRNA and circRNA abundance during secukinumab (anti-IL-17A) treatment, we studied their expression patterns in skin biopsies from 14 patients with severe plaque-type psoriasis before and during an 84-day secukinumab therapy at day 0, 4, 14, 42, and 84 using NanoString nCounter technology. We found a comprehensive downregulation of the majority of investigated circRNAs and specific alterations in the miRNA profile, including an upregulation of miR-203a-3p, miR-93-5p, and miR-378i in lesional compared to non-lesional skin before treatment. During treatment, the circRNAs progressively returned to the expression levels observed in non-lesional skin and already four days after treatment initiation most circRNAs were significantly upregulated. In comparison, for miRNAs, the normalization to baseline during treatment was delayed and limited to a subset of miRNAs. Moreover, we observed a strong correlation between multiple circRNAs, including ciRS-7 and circPTPRA, and the psoriasis area and severity index (PASI). Similar pronounced correlations could, however, not be found for miRNAs. Finally, we did not observe any significant changes in circRNA expression in peripheral blood mononuclear cells during treatment. In conclusion, we uncovered a rapid shift in global circRNA abundance upon anti-IL-17A treatment, which predated clinical and histological improvements, and a strong correlation with PASI, indicating a biomarker potential of individual circRNAs.

Abstract
INTRODUCTION Treatment with biologics often leads to clearance of psoriasis. However, some patients do repeatedly fail to respond and/or lose an achieved response (treatment refractory) to the biologic, whereas other patients achieve excellent response to one biologic and remain clear of psoriasis for several years (super-responders). OBJECTIVE To identify and characterize patients with treatment refractory psoriasis and patients who are super-responders to biologic treatment. MATERIAL AND METHODS Patients registered in DERMBIO between January 2007 and November 2019 were included. Patients were categorized as being treatment refractory if they had had treatment failure to ≥3 biologics targeting ≥2 different pathways. Super-responders were patients treated with their first biologic for minimum 5 years without an absolute psoriasis area and severity index (PASI) > 3 between 6 months and 5 years of treatment. All remaining patients from DERMBIO served as comparators. RESULTS In total, 3280 patients were included with a mean age of 45.0 years. 1221 (37%) of the patients were females. Of the included patients, 214 (6.5%) were categorized as treatment refractory and 207 (6.3%) were categorized as super-responders. Treatment refractory patients had higher mean body weight (100.6 kg vs. 90.6 kg, P < 0.0001) and higher mean BMI (32.2 vs. 29.4, P < 0.0001) compared with the rest of patients in DERMBIO. Super-responders had higher socioeconomic status and fewer comorbidities compared with the comparator group (P < 0.0001). CONCLUSION A small proportion of patients with psoriasis treated with biologics are either super-responders or treatment refractory. Treatment refractory patients have higher body weight, whereas super-responders have fewer comorbidities and higher socioeconomic status.

Abstract
Altered miRNA expressions are assigned pathogenic properties in several cancers including mycosis fungoides and could play a role in the early onset of the disease. The aim of this study was to examine disease-specific miRNA expression in early-stage mycosis fungoides patch and plaque lesions. A quantitative real-time PCR platform of 384 human miRNAs was used to study miRNA expression in 154 diagnostic mycosis fungoides biopsies. A total of 110 miRNAs were significantly differentially expressed (>2-fold, p < 0.05) between plaque lesions and healthy controls, and 90 miRNAs (>2-fold, p < 0.05) differed between patch lesions and healthy controls. Moreover, 13 miRNAs differed in expression between patch and plaque lesions. Early-stage mycosis fungoides exhibited miRNA features that overlapped with those of psoriasis. However, 39 miRNAs, including miR-142-3p, miR-150 and miR-146b, were specific to mycosis fungoides. In conclusion, early-stage mycosis fungoides expresses a distinct miRNA profile, indicating that miRNAs could play a role in the early development of mycosis fungoides.

Abstract
Psoriasis is associated with several comorbidities ranging from cardiovascular comorbidity and mental disorders to other immune mediated inflammatory diseases. However, most of these co-morbidities are often overlooked or diagnosed late. Furthermore, evidence suggests that comorbidities are undertreated. Here, we provide an overview of comorbidities in psoriasis and present a simple rundown of considerations of relevance to the clinician. We hope that this review may raise clinicians' awareness of comorbidities in psoriasis and provide simple guidance regarding screening tools and treatment decisions in psoriasis with comorbidities.

Abstract
Importance Given the possible treatment modalities in psoriasis management, little is known about whether drug monitoring is associated with response rate. Objective To determine whether drug monitoring is associated with response to brodalumab therapy. Design A multicenter case series study of patients with psoriasis treated with brodalumab whose treatment with previous IL-17A inhibitor therapy failed. Patients were recruited from the Departments of Dermatology at Gentofte and Aarhus University Hospitals, Denmark, between 2018 and 2020. Patient visits were conducted after 4 and 12 weeks of therapy. Patients not achieving Psoriasis Area and Severity Index 75% improvement from baseline (PASI 75) after 12 weeks were discontinued and considered nonresponders. Patients maintaining PASI 75 response were followed up for up to 52 weeks. Exposure Treatment with brodalumab, 210 mg, at weeks 0, 1, 2, then every 2 weeks. Main Outcomes and Measures Outcome measures were PASI reductions vs brodalumab levels and antibrodalumab antibodies. Results Twenty patients with psoriasis (13 [65%] were male; median age, 50 years [range, 19-66 years]) were included. After 12 weeks of therapy, patients with quantifiable levels of brodalumab (≥0.05 μg/mL) experienced significantly higher PASI reductions than those without (median, 93%; range, 61%-100% vs median, -3; range, -49% to 94%, respectively; P = .006). After 12 weeks of therapy, 4 of 5 patients (80%) not achieving PASI 75 had subquantifiable drug levels (<0.05 μg/mL), although this finding was seen for only 3 of 14 PASI 75 responders (21%). None of 7 patients (35%) with subquantifiable drug levels after 12 weeks of therapy maintained response. No antibrodalumab antibodies were detected in any of the tested samples. Conclusions and Relevance Results of this case series study suggest that circulating brodalumab level is a factor associated with clinical treatment response. Monitoring patient levels of circulating brodalumab may aid clinical decision-making and help prevent ineffective therapy.

Abstract
BackgroundImmune-Mediated Inflammatory Diseases (IMIDs), including psoriatic arthritis (PsA), axial spondyloarthritis (AxSpA), psoriasis, hidradenitis suppurativa, and inflammatory bowel disease share both pathophysiological and environmental factors, individuals with one IMID have an increased risk for developing other IMIDs, and are associated with reduced health-related quality of life, increased risk of comorbidities, and reduced socioeconomic status.Unmet needs in care of patients with IMIDs may result from lack of patient-centricity in the usual mono-disciplinary siloed approach to these diseases.ObjectivesThe overall aim of this study is to determine the effectiveness of an interdisciplinary combined clinic intervention compared to usual care in patients with the aforementioned IMIDs.MethodsThis is a randomized, usual care controlled, parallel-group pragmatic clinical trial. 300 consecutively enrolled participants with co-occurrence of at least two IMIDs are randomly assigned 2:1 to either treatment in the interdisciplinary combined clinic or usual care. The study consists of a 6-month active intervention period and a 6-month follow-up period. Primary outcome is change from baseline to 24-Weeks on the Short-Form Health Survey (SF-36). Additional questionnaire-based qualitative date from 30 patients and 15 health-care professional (HCP)s involved in the center are reported.ResultsHere we report baseline characteristics of the first 128 patients (mean age: 45.4y, 18–74.2, females (83, 64.8%)). All patients had ≥2 IMIDs: Psoriasis (99, 77.3%), PsA (peripheral) (72, 56.3%), AxSpA (34, 26.6%), Hidradenitis (16, 12.5%), Crohn (35, 27.3%), Colitis (20, 15.6%), AxPsA (9, 7.0%), IBD-associated arthritis (10, 7.8%), HS-associated arthritis (1, 0.8%). HLA-B27 was positive in 24 (22.2%) patients.Advantages, challenges and themes mentioned by the patients are listed in Table 1.Table 1.Advantages and challenges on feedback from 15 HCPs and feedback from 30 patients.Advantages - HCPChallenges - HCPThemes mentioned by the patientsProfessional developmentCulture -Old habits from regular departments-“This is how we usually do this”Communication between HCOs improved treatmentSatisfying to work on a high professional levelCreate a new culture takes time and patience-Large differences between specialties and subject areasCollaboration between HCPs improved treatmentImproved perspective on diseases and patientsLogistics, physical requirementsHolistic approach –patients felt HCPs cared for all health aspectsCollaboration – professional, personal, team spiritShared goalsConfidence in living with diseasesMeaning full to work with all aspects of diseaseTime and patienceCoherenceEffective communicationOptimal use of time and resourcesTreatment optimizationLearning can be brought back to “monodisciplinary” work (improved treatment in respective departments)Clarification about diet, mastering fatigue and work-related problemsBroader disease focusAvoid patient being information carrierReflectionA statement from a patient: “It gave me much more peace of mind that I should not “split” my health problems and run errands between different departments.

Abstract
Importance A clear dosing regimen for methotrexate in psoriasis is lacking, and this might lead to a suboptimal treatment. Because methotrexate is affordable and globally available, a uniform dosing regimen could potentially optimize the treatment of patients with psoriasis worldwide. Objective To reach international consensus among psoriasis experts on a uniform dosing regimen for treatment with methotrexate in adult and pediatric patients with psoriasis and identify potential future research topics. Design, Setting, and Participants Between September 2020 and March 2021, a survey study with a modified eDelphi procedure that was developed and distributed by the Amsterdam University Medical Center and completed by 180 participants worldwide (55 [30.6%] resided in non-Western countries) was conducted in 3 rounds. The proposals on which no consensus was reached were discussed in a conference meeting (June 2021). Participants voted on 21 proposals with a 9-point scale (1-3 disagree, 4-6 neither agree nor disagree, 7-9 agree) and were recruited through the Skin Inflammation and Psoriasis International Network and European Academy of Dermatology and Venereology in June 2020. Apart from being a dermatologist/dermatology resident, there were no specific criteria for participation in the survey. The participants worked mainly at a university hospital (97 [53.9%]) and were experienced in treating patients with psoriasis with methotrexate (163 [91.6%] had more than 10 years of experience). Main Outcomes and Measures In a survey with eDelphi procedure, we tried to reach consensus on 21 proposals. Consensus was defined as less than 15% voting disagree (1-3). For the consensus meeting, consensus was defined as less than 30% voting disagree. Results Of 251 participants, 180 (71.7%) completed all 3 survey rounds, and 58 participants (23.1%) joined the conference meeting. Consensus was achieved on 11 proposals in round 1, 3 proposals in round 2, and 2 proposals in round 3. In the consensus meeting, consensus was achieved on 4 proposals. More research is needed, especially for the proposals on folic acid and the dosing of methotrexate for treating subpopulations such as children and vulnerable patients. Conclusions and Relevance In this eDelphi consensus study, consensus was reached on 20 of 21 proposals involving methotrexate dosing in patients with psoriasis. This consensus may potentially be used to harmonize the treatment with methotrexate in patients with psoriasis.

Abstract
Immunohistochemical quantification of inflammatory cells in skin biopsies is a valuable tool for diagnosing skin diseases and assessing treatment response. The quantification of individual cells in biopsies is time-consuming, tedious, and difficult. In this study, we presented and compared two methods for the quantification of CD8+ T cells in skin biopsies from patients with psoriasis using both commercial software (Adobe Photoshop) and open-source software (Qupath). In addition, we provided a detailed, step-by-step description of both methods. The methods are scalable by replacing the CD8 antibody with other antibodies to target different cells. Moreover, we investigated the correlation between quantifying CD8+ cells normalized to area or epidermal length and cell classifications, compared cell classifications in QuPath with threshold classifications in Photoshop, and analyzed the impact of data normalization to epidermal length or area on inflammatory cell densities in skin biopsies from patients with psoriasis. We found a satisfactory correlation between normalizing data to epidermal length and area for psoriasis skin. However, when non-lesional and lesional skin samples were compared, a significant underestimation of inflammatory cell density was found when data were normalized to area instead of epidermal length. Finally, Bland–Altman plots comparing Qupath and Photoshop to quantify inflammatory cell density demonstrated a good agreement between the two methods.

Abstract
Climatotherapy is a well‐described treatment of psoriasis. Dead Sea climatotherapy (DSC) in Israel consists of intensive sun and Dead Sea bathing and is very effective in improving clinical and patient‐reported outcomes. However, the effect of DSC has not been widely studied. We aimed to investigate the effect of DSC on psoriasis skin using quantitative immunohistochemistry techniques and analysis of blood samples. Skin punch biopsies from 18 psoriasis patients from a previous cohort study were used. Biopsies were obtained from non‐lesional skin and from a psoriasis target lesion at baseline. A biopsy was acquired from the target lesion after DSC. Among patients who achieved complete visual clearance, a biopsy was also obtained at relapse. Blood samples were obtained at the same time points. We performed haematoxylin and eosin staining and quantitative immunohistochemical analysis of CD3, CD4, CD8, CD11c, CD103, CD163, CD207, forkhead box P3, Ki67 and myeloperoxidase. We performed blood tests of cholesterol, c‐reactive protein, glucose, haemoglobin A1c and triglycerides. All skin biomarkers except for CD207 were decreased after DSC. At relapse, none of the biomarkers were significantly different from the baseline lesional measurements. Total CD207 staining correlated with psoriasis area and severity index at baseline while CD163 staining correlated with psoriasis area and severity index at EOT. No changes were observed in selected blood tests during the study. Consistent with clinical results, DSC is highly effective in the short term almost normalising all investigated biomarkers. However, at relapse, biomarkers were upregulated to the baseline level.

Abstract
BACKGROUND HSP90 is a downstream regulator of tumor necrosis factor α (TNFα) and interleukin (IL)-17A signaling and may therefore serve as a novel target in the treatment of psoriasis. OBJECTIVE This phase 1b proof-of-concept study was undertaken to evaluate the safety and efficacy of a novel HSP90 inhibitor (RGRN-305) in the treatment of plaque psoriasis. METHODS An open-label, single-arm, dose-selection, single-center proof-of-concept study. Patients with plaque psoriasis were treated with 250 mg or 500 mg RGRN-305 daily for 12 weeks. Efficacy was evaluated clinically using Psoriasis Area and Severity Index (PASI), body surface area (BSA), and Physician Global Assessment (PGA) scores and by Dermatology Life Quality Index (DLQI). Skin biopsies collected at baseline and at 4, 8, and 12 weeks after treatment start were used for immunohistochemical staining and for gene expression analysis. Safety was monitored via laboratory tests, vital signs, ECG, and physical examinations. RESULTS Six of the eleven patients completing the study responded to RGRN-305 with a PASI improvement between 71% and 94%, whereas five patients were considered nonresponders with a PASI response < 50%. No severe adverse events were reported. Four of seven patients treated with 500 mg RGRN-305 daily experienced a mild to moderate exanthematous drug induced eruption due to study treatment. Two patients chose to discontinue the study due to this exanthematous eruption. RGRN-305 treatment resulted in pronounced inhibition of the IL-23, TNFα, and IL-17A signaling pathways and normalization of both histological changes and psoriatic lesion gene expression profiles in patients responding to treatment. CONCLUSION Treatment with RGRN-305 showed an acceptable safety, especially in the low-dose group, and was associated with clinically meaningful improvement in a subset of patients with plaque psoriasis, indicating that HSP90 may serve as a novel future target in psoriasis treatment.

Abstract
BACKGROUND Psoriasis, psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA) are chronic inflammatory diseases that often affect women of childbearing age. Detailed information about pregnancy and related outcomes across these indications in patients exposed to ixekizumab is lacking. OBJECTIVES To evaluate pregnancy outcomes after maternal or paternal exposure to ixekizumab in patients with psoriasis, PsA, or axSpA. METHODS Pregnancy cases from clinical trials and post-marketing reports, associated with either maternal or paternal exposure to ixekizumab cumulatively through 22 March 2019, were identified in the Eli Lilly Global Safety Database and described separately. RESULTS One hundred and ninety-three ixekizumab-exposed pregnancies were identified. Maternal exposure occurred in 51.3% of pregnancies (clinical trials: n = 58; post-marketing: n = 41). The majority of paternal exposure pregnancies occurred in clinical trials (91 of 94). Live births were reported for 53.8 and 61.1% of known outcomes in maternal exposure pregnancies during clinical trials and post-marketing surveillance, respectively. No congenital malformations resulting from maternal exposure were reported in clinical trials: one case, not causally related to ixekizumab therapy, was recorded in the post-marketing setting. CONCLUSIONS This integrated safety analysis provides relevant information for clinicians treating patients with psoriasis, PsA, or axSpA with ixekizumab. No new safety signals were identified in patients receiving ixekizumab.

Abstract
OBJECTIVES (i) To estimate the prevalence and severity of coronary artery disease and (ii) to assess the risk of cardiovascular events and mortality, in patients with psoriasis and psoriatic arthritis (PsA) in a large-scale cohort of patients referred to coronary computed tomography angiography (CTA). METHODS This was a cross-sectional study with follow-up of 46,022 patients based on data from a Danish national CTA registry. Exposure was defined as psoriasis or PsA. A group of patients without psoriasis, PsA or any other inflammatory disease was used as reference. Cross-sectional primary outcomes were a coronary artery calcium score (CACS) >0 and CACS ≥400, and secondary outcome was obstructive CAD. At follow-up, the primary outcome was a composite endpoint of cardiovascular events and all-cause mortality. All outcomes were adjusted for traditional cardiovascular risk factors. RESULTS We identified 1356 psoriasis and 370 PsA patients. The adjusted odds ratio (OR) for psoriasis patients for CACS >0, CACS ≥400 and obstructive CAD was 1.26 (1.10-1.46), 1.25 (1.04-1.50) and 1.14 (0.98-1.33), respectively. For PsA patients, OR for CACS >0 was 1.28 (1.00-1.64). We found a crude hazard ratio (HR) of 1.49 (1.21-1.85) and adjusted HR of 1.14 (0.92-1.41) for the primary outcome in psoriasis patients. CONCLUSIONS In this population, both psoriasis and PsA were associated with an increased prevalence of coronary calcification. Psoriasis patients also showed an increased prevalence of severe calcification. Psoriasis patients were at increased risk for cardiovascular events and death, however not after adjusting for the effect of other predictors.

Abstract
Studies on switch between interleukin (IL)-17 inhibitors are scarce. We assessed the effectiveness of brodalumab in patients with previous treatment failure of IL-17A inhibitor(s). Patients with psoriasis and previous treatment failure of an IL-17A inhibitor were treated with brodalumab at standard dose. Effectiveness was assessed after 12, 26, and 52 weeks of treatment. The primary outcome was the proportion of patients that had achieved an absolute psoriasis area and severity index (PASI) ≤2 and/or a relative reduction of PASI of 75% (PASI75) at week 12. Plasma cytokine levels were measured at baseline and after 12 weeks of treatment. In total, 20 patients were included, seven (35%) were female, the median age was 50 years, and the median baseline PASI was 13.5. Analyzing the data using nonresponder imputation, 14 (70%) patients had achieved either PASI75 and/or PASI ≤2, 8 (40%) had achieved PASI90, and three (15%) had achieved PASI100 at week 12. In total, nine patients (45%) completed the 52-weeks trial and seven patients (35%) still had PASI75 throughout 52 weeks. Seventeen out of 20 patients experienced any adverse events (AEs) during 52 weeks with no serious AEs or deaths. Patients responding to treatment had lower levels of tumor necrosis factor (TNF)-α and IL-6 at baseline compared with those who did not respond to treatment (TNF-α, p = 0.041, IL-6, p = 0.0054). In conclusion, treatment with brodalumab despite previous treatment failure with an IL-17A inhibitor can be effective and well-tolerated.

Abstract
In health, the non-recirculating nature and long-term persistence of tissue-resident memory T cells (TRMs) in tissues protects against invading pathogens. In disease, pathogenic TRMs contribute to the recurring traits of many skin diseases. We aimed to conduct a systematic literature review on the current understanding of the role of TRMs in skin diseases and identify gaps as well as future research paths. EMBASE, PubMed, SCOPUS, Web of Science, Clinicaltrials.gov and WHO Trials Registry were searched systematically for relevant studies from their inception to October 2020. Included studies were reviewed independently by two authors. This study was conducted in accordance with the PRISMA-S guidelines. This protocol was registered with the PROSPERO database (ref: CRD42020206416). We identified 96 studies meeting the inclusion criteria. TRMs have mostly been investigated in murine skin and in relation to infectious skin diseases. Pathogenic TRMs have been characterized in various skin diseases including psoriasis, vitiligo and cutaneous T-cell lymphoma. Studies are needed to discover biomarkers that may delineate TRMs poised for pathogenic activity in skin diseases and establish to which extent TRMs are contingent on the local skin microenvironment. Additionally, future studies may investigate the effects of current treatments on the persistence of pathogenic TRMs in human skin.

Abstract
Lipases comprise one of the major enzyme classes in biotechnology with applications within, e.g., baking, brewing, biocatalysis, and the detergent industry. Understanding the mechanisms of lipase function and regulation is therefore important to facilitate the optimization of their function by protein engineering. Advances in single-molecule studies in model systems have provided deep mechanistic insights on lipase function, such as the existence of functional states, their dependence on regulatory cues, and their correlation to activity. However, it is unclear how these observations translate to enzyme behavior in applied settings. Here, single-molecule tracking of individual Thermomyces lanuginosus lipase (TLL) enzymes in a detergency application system allowed real-time direct observation of spatiotemporal localization, and thus diffusional behavior, of TLL enzymes on a lard substrate. Parallelized imaging of thousands of individual enzymes allowed us to observe directly the existence and quantify the abundance and interconversion kinetics between three diffusional states that we recently provided evidence to correlate with function. We observe redistribution of the enzyme's diffusional pattern at the lipid-water interface as well as variations in binding efficiency in response to surfactants and calcium, demonstrating that detergency effectors can drive the sampling of lipase functional states. Our single-molecule results combined with ensemble activity assays and enzyme surface binding efficiency readouts allowed us to deconvolute how application conditions can significantly alter protein functional dynamics and/or surface binding, both of which underpin enzyme performance. We anticipate that our results will inspire further efforts to decipher and integrate the dynamic nature of lipases, and other enzymes, in the design of new biotechnological solutions.
