[PMID: 38426052 PMCID: PMC10902440 DOI: 10.3389/fmicb.2024.1287637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Accepted: 01/24/2024] [Indexed: 03/02/2024] Open
Abstract
Background Currently, there has been observed a significant alteration in the composition of the gut microbiome (GM) and serum metabolites in patients with psoriatic arthritis (PsA) compared to healthy individuals. However, previous observational studies have shown inconsistent results regarding the alteration of gut microbiota/metabolites. In order to shed light on this matter, we utilized Mendelian randomization to determine the causal effect of GM/metabolites on PsA. Methods We retrieved summary-level data of GM taxa/metabolites and PsA from publicly available GWAS statistics. Causal relationships between GM/metabolites and PsA were determined using a two-sample MR analysis, with the IVW approach serving as the primary analysis method. To ensure the robustness of our findings, we conducted sensitivity analyses, multivariable MR analysis (MVMR), and additional analysis including replication verification analysis, LDSC regression, and Steiger test analysis. Furthermore, we investigated reverse causality through a reverse MR analysis. Finally, we conducted an analysis of expression quantitative trait loci (eQTLs) involved in the metabolic pathway to explore potential molecular mechanisms of metabolism. Results Our findings reveal that eight GM taxa and twenty-three serum metabolites are causally related to PsA (P < 0.05). Notably, a higher relative abundance of Family Rikenellaceae (ORIVW: 0.622, 95% CI: 0.438-0.883, FDR = 0.045) and elevated serum levels of X-11538 (ORIVW: 0.442, 95% CI: 0.250-0.781, FDR = 0.046) maintain significant causal associations with a reduced risk of PsA, even after adjusting for multiple testing correction and conducting MVMR analysis. These findings suggest that Family Rikenellaceae and X-11538 may have protective effects against PsA. Our sensitivity analysis and additional analysis revealed no significant horizontal pleiotropy, reverse causality, or heterogeneity. The functional enrichment analysis revealed that the eQTLs examined were primarily associated with glycerolipid metabolism and the expression of key metabolic factors influenced by bacterial infections (Vibrio cholerae and Helicobacter pylori) as well as the mTOR signaling pathway. Conclusion In conclusion, our study demonstrates that Family Rikenellaceae and X-11538 exhibit a strong and negative causal relationship with PsA. These particular GM taxa and metabolites have the potential to serve as innovative biomarkers, offering valuable insights into the treatment and prevention of PsA. Moreover, bacterial infections and mTOR-mediated activation of metabolic factors may play an important role in this process.

Real-world effectiveness and persistence of secukinumab in the treatment of patients with psoriatic arthritis. Front Med (Lausanne) 2023; 10:1294247. [PMID: 38053615 PMCID: PMC10694458 DOI: 10.3389/fmed.2023.1294247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 11/03/2023] [Indexed: 12/07/2023] Open
Abstract
Introduction Psoriatic arthritis (PsA) is a complex and heterogeneous inflammatory disease. Secukinumab, a biologic disease-modifying antirheumatic drug (bDMARD), has extensive clinical evidence of efficacy and safety in the treatment of PsA but data in clinical practice are still limited. This study aims to provide real-world evidence on secukinumab use, effectiveness, and persistence in PsA. Methods A retrospective, multicenter study was conducted on patients diagnosed with PsA and treated with secukinumab up to June 2021 at 12 centers in the Valencian Community (Spain). Data on DAS28-CRP, DAPSA, Tender and Swollen Joint Counts (TJC, SJC), enthesitis, dactylitis, skin and nail involvement, pain, patient and physician global assessment (ptGA, phGA) using 100-mm visual analog scale (VAS), and persistence for up to 24 months were collected. Results A total of 178 patients were included (49% men; mean [standard deviation, SD] age: 51.4 [10.5] years; 39% obese). Secukinumab was used as a first-, second-, or ≥ third-line bDMARD in 37, 21, and 42% of patients, respectively. The percentage of patients achieving at least low disease activity (DAS28-CRP ≤ 3.2) increased from 25% at baseline to 66% at month 6 (M6) and was maintained (75%) up to M24. Mean (SD) DAS28-CRP baseline values (3.9 [1.2]) decreased to 2.9 (1.1) (p < 0.001) at M6 and remained low through M24 (2.6 [1.1]) (p < 0.001). Secukinumab also improved peripheral arthritis increasing the percentage of patients with TJC = 0 (20% baseline; 57% M24) and SJC = 0 (37% baseline; 80% M24). Treatment reduced the percentage of patients with enthesitis (25% baseline; 6% M24), dactylitis (20% baseline; 4% M24), and skin (70% baseline; 17% M24), and nail (32% baseline; 2% M24) involvement. Additionally, we observed improvements in the mean pain VAS (-26.4 mm M24), ptGA (-26.2 mm M24), and phGA (-24.8 mm M24). Secukinumab showed an overall 24-month persistence rate of 67% (95% confidence interval [CI]: 60-74%). Patients receiving first-line secukinumab showed the highest 24-month persistence rate (83, 95% CI: 73-92; p = 0.024). Conclusion Secukinumab showed long-term effectiveness across the six key PsA domains thus reducing disease activity and pain, which are major treatment goals. This was accompanied by high persistence rates, especially in bDMARD naive patients.

Abstract
Psoriatic arthritis (PsA) is associated with psoriasis, featured by its irreversible joint symptoms. Despite the significant impact on the healthcare system, it is still challenging to leverage machine learning or statistical models to predict PsA and its progression, or analyze drug efficacy. With 3961 patients' clinical records, we developed a machine learning model for PsA diagnosis and analysis of PsA progression risk, respectively. Furthermore, general additive models (GAMs) and the Kaplan-Meier (KM) method were applied to analyze the efficacy of various drugs on psoriasis treatment and inhibiting PsA progression. The independent experiment on the PsA prediction model demonstrates outstanding prediction performance with an AUC score of 0.87 and an AUPR score of 0.89, and the Jackknife validation test on the PsA progression prediction model also suggests the superior performance with an AUC score of 0.80 and an AUPR score of 0.83, respectively. We also identified that interleukin-17 inhibitors were the more effective drug for severe psoriasis compared to other drugs, and methotrexate had a lower effect in inhibiting PsA progression. The results demonstrate that machine learning and statistical approaches enable accurate early prediction of PsA and its progression, and analysis of drug efficacy.

Abstract
INTRODUCTION Psoriatic arthritis (PsA) is a chronic arthritis typically associated with cutaneous psoriasis (PsO). Its pathogenesis is connected to an innate and acquired immune response, as well as genetic risk alleles. The extent of immunopathogenic mechanisms and the heterogenicity of clinical manifestation make the identification of patient-targeted therapies a critical issue, and the treatment decision challenging in patients' management. AREAS COVERED This review includes a brief overview of biological and small-molecule therapies, focusing on evidence from clinical trials and real-world data that support their use in PsA. We summarize novel and future possible therapeutic strategies, the importance that comorbidities have on selection of therapy and discuss the adverse event of each drug. Relevant papers for up to 1 August 2022 (trials, real-life studies, and reviews) regarding biologics and/or small molecules were summarized. EXPERT OPINION In recent years, the treatment of PsA has been revolutionized by new targeted therapies, which offer the opportunity to perform a tailored-tail management, considering risk factors, comorbidities, and the different PsA phenotypes. Growing experience with these new agents allows novel treatment approaches that may improve clinical outcomes for PsA patients, in terms of remission/low disease activity and quality of life.

Biologic Initiation Rate in Systemic-Naïve Psoriatic Arthritis Patients Starting Treatment with Apremilast vs Methotrexate: 1-Year Retrospective Analysis of a US Claims Database. Open Access Rheumatol 2022; 14:123-132. [PMID: 35734243 PMCID: PMC9207121 DOI: 10.2147/oarrr.s342123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Accepted: 05/03/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose To compare the rate of biologic initiation after commencing treatment with apremilast (APR) vs methotrexate (MTX), in systemic-naïve patients with psoriatic arthritis (PsA). Patients and Methods Systemic-naïve patients with PsA who started treatment with either APR or MTX between 01/01/2015 and 12/31/2018 were analyzed using claims data from the IBM® MarketScan® Commercial and Medicare Supplemental databases (2014-2019). PsA patients were identified via diagnosis codes; the first prescription date for APR or MTX was the index date. Patient demographics, clinical characteristics, healthcare utilization during the year pre-index (baseline) and the year post-index (follow-up), and median time to biologic initiation were reported descriptively. The rates and risk of biologic initiation during follow-up were compared between APR and MTX users by logistic and Cox regressions, respectively. Models were adjusted for demographics, clinical and utilization measures during the baseline period. Results A total of 2116 patients with PsA newly treated with APR (n = 534) or MTX (n = 1582) were identified. Mean age was similar (50.5 vs 50.4; P = 0.938), and proportion of females was higher for APR vs MTX users (59.4% vs 54.0%; P = 0.031). Mean time to biologic initiation among patients who initiated during follow-up was 194.1 vs 138.7 days between APR vs MTX users (P < 0.001). After adjusting for confounders, the likelihood of biologic initiation was 58% lower (OR, 0.42 [95% CI, 0.32-0.54]; P < 0.001) with APR, with a significantly lower predicted rate of biologic initiation among APR users when compared to MTX users during follow-up (20.0% [95% CI, 16.6-23.9%] vs 37.5% [95% CI, 35.0-40.1%]). Additionally, APR users had a lower risk of biologic initiation than MTX users (HR, 0.46 [95% CI, 0.37-0.57]; P < 0.001) during the 1-year follow-up. Conclusion Systemic-naïve patients with PsA have a lower rate of, and longer time to, biologic initiation over one-year following APR initiation, compared to those initiating MTX.

Vaccination for SARS-CoV-2 in Patients With Psoriatic Arthritis: Can Therapy Affect the Immunological Response? Front Med (Lausanne) 2022; 9:811829. [PMID: 35295608 PMCID: PMC8918942 DOI: 10.3389/fmed.2022.811829] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 01/25/2022] [Indexed: 12/13/2022] Open
Abstract
Background A few studies on vaccination in patients with rheumatic diseases, including arthritis, connective tissue diseases, vasculitis, and psoriatic arthropathy (PsA), demonstrated reduced production of neutralizing antibodies to SARS-CoV-2 Spike RBD (receptor-binding domain contained in the N-terminal of the S1 globular head region) when compared to the general population. Objective The aim of our study was to observe whether different therapies for PsA [methotrexate, anti-TNF antibodies, soluble TNF receptor (etanercept) or IL-17 inhibitors] have a different impact on SARS-CoV-2 vaccination in a homogeneous population of patients. Methods We enrolled 110 PsA patients in remission, assessed with Disease Activity in PSoriatic Arthritis (DAPSA). Of these: 63 were in treatment with anti-TNF-α therapy (26 etanercept, 15 certolizumab, 5 golimumab, 17 adalimumab); 37 with anti-IL17 secukinumab; 10 with methotrexate. All patients underwent vaccination for SARS-CoV-2 with mRNA BNT162b2 vaccine. Assessment of absolute and percentage lymphocyte subsets and anti-SARS-CoV-2 Spike RBD IgG antibody value 3 weeks after the second vaccine dose were performed. In addition, the serum antibody levels of 96 healthy healthcare workers (HCW) were analyzed. Results The mean disease activity assessed with DAPSA score was 2.96 (SD = 0.60) with no significant differences between patients under different medications (p = 0.779). Median levels of neutralizing antibodies to SARS-CoV-2 Spike RBD were 928.00 binding antibody unit (BAU)/mL [IQR 329.25, 1632.0]; 1068.00 BAU/ml [IQR 475.00, 1632.00] in patients taking MTX, 846.00 BAU/ml [IQR 125.00, 1632.00] in patients taking etanercept, 908.00 BAU/mL [IQR 396.00, 1632.00] in patients taking anti-IL17 and 1148.00 BAU/ml [IQR 327.00, 1632.00] in patients taking TNF-α inhibitors, without statistically significant differences between these groups. Mean serum antibody level of HCW group was 1562.00 BAU/ml [IQR 975.00, 1632.00], being significantly higher than in the patient group (p = 0.000816). Absolute and percentage count of lymphocyte subsets were not statistically different between the subgroups under different treatments and when compared with HCW. Conclusions As for other rheumatic diseases on immunomodulatory treatment, our data showed a reduced humoral response in PsA patients compared to the control group. However, antibody response did not significantly differ between groups treated with different medications.

Abstract
Objective Ixekizumab is a monoclonal antibody targeting IL-17A and licensed for psoriasis, psoriatic arthritis (PsA) and axial spondyloarthritis. Review objectives were to summarize: 1) ixekizumab safety in people with PsA, 2) ixekizumab efficacy from Phase III randomized controlled trials, and 3) ixekizumab study participant PsA phenotypes. Methods We conducted a search in PubMed limited to phase III randomized controlled trials (RCT) and corresponding long-term extension studies where the intervention was treatment with ixekizumab in a population with PsA. Results We identified 17 publications and 13 met inclusion criteria. Injection site reactions (ISR) and allergic reactions occurred in up to 25.3% and 6.2% with ixekizumab and 4.5% and 1.85, respectively, with placebo. ISR occurred in 9.5-10.6% at 24 and 52 weeks with ixekizumab versus 3.2-3.5% with adalimumab (p < 0.01) in biologic-naïve PsA. Serious adverse events at 24 weeks occurred in 8.5% with adalimumab versus 3.5% with ixekizumab (p = 0.02), and at 52 weeks in 12.45 with adalimumab and 4.25 with ixekizumab (p < 0.01). Ixekizumab had similar efficacy to adalimumab across all PsA musculoskeletal, symptom and patient-reported outcome domains and surpassed adalimumab in psoriasis outcomes as well as all combined musculoskeletal and psoriasis outcomes. The study subject population was overwhelmingly white, balanced men-women, BMI at the obese threshold, had on average 7-year PsA duration and 15-year psoriasis duration. Disease activity was high with 7/66 swollen joints, 13/68 tender joints, 55% enthesitis, variable dactylitis (12-51%), and active psoriasis in >92%. Conclusion Ixekizumab treatment in PsA was associated with a statistically significant higher risk of injection site reactions versus placebo or adalimumab. Ixekizumab had statistically significantly fewer serious adverse events than adalimumab. Ixekizumab demonstrated efficacy for all PsA disease activity domains as well as for slowing radiographic disease progression. The main shortcoming of the ixekizumab PsA program is lack of representation of African American study participants.

Abstract
Psoriatic arthritis is a chronic inflammatory condition that can lead to severe functional impairment and irreversible damage. The diagnosis can be difficult in early cases where the clinical exam is often scarce. The lack of a serological biomarker can lead to a considerable delay in diagnosis. In this review, we discuss the existent imaging methods that have improved the diagnosis of psoriatic arthritis (PsA). The degree and type of musculoskeletal involvement cannot be assessed by only one imaging method. We think that a combination of methods is the best approach to evaluate both structural damage and inflammatory lesions and that ultrasound (US) could be the best tool to screen a patient when considering the diagnosis of PsA. US is an accessible, non-ionizing technique that offers information regarding active inflammation in joints, entheses, and soft tissues.

Abstract
Greater than 90% of patients with psoriatic arthritis (PsA) first develop their arthritis on a background of known psoriasis (Pso). Thus, having skin/nail Pso certainly is an important risk factor for PsA but as PsA develops in <30% of those affected with Pso, the presence of Pso alone is insufficient as a means of identifying which patients with Pso will develop PsA. It is hoped that with further molecular assessment of Pso patients who do not have any evidence of inflammatory musculoskeletal disease compared to those with early PsA features, that the “at risk” profile of Pso patients destined to develop PsA can be refined such that disease prevention studies can be designed and a new era of treatment for PsA can emerge. In this article, the early stages in the development of PsA are outlined and what is currently known about clinical features, genetic factors and soluble or tissue biomarkers associated with the development of PsA in patients with Pso is reviewed in detail. Finally, proposals are outlined regarding the approaches required in order to address this important research area.

Importance of lymphocyte-stromal cell interactions in autoimmune and inflammatory rheumatic diseases. Nat Rev Rheumatol 2021; 17:550-564.

Abstract
Interactions between lymphocytes and stromal cells have an important role in immune cell development and responses. During inflammation, stromal cells contribute to inflammation, from induction to chronicity or resolution, through direct cell interactions and through the secretion of pro-inflammatory and anti-inflammatory mediators. Stromal cells are imprinted with tissue-specific phenotypes and contribute to site-specific lymphocyte recruitment. During chronic inflammation, the modified pro-inflammatory microenvironment leads to changes in the stromal cells, which acquire a pathogenic phenotype. At the site of inflammation, infiltrating B cells and T cells interact with stromal cells. These interactions induce a plasma cell-like phenotype in B cells and T cells, associated with secretion of immunoglobulins and inflammatory cytokines, respectively. B cells and T cells also influence the stromal cells, inducing cell proliferation, molecular changes and cytokine production. This positive feedback loop contributes to disease chronicity. This Review describes the importance of these cell interactions in chronic inflammation, with a focus on human disease, using three selected autoimmune and inflammatory diseases: rheumatoid arthritis, psoriatic arthritis (and psoriasis) and systemic lupus erythematosus. Understanding the importance and disease specificity of these interactions could provide new therapeutic options.

Abstract
Psoriatic arthritis (PsA) is a complex inflammatory disease with heterogeneous clinical features, which complicates psoriasis in 30% of patients. There are no diagnostic criteria or tests available. Diagnosis is most commonly made by identifying inflammatory musculoskeletal features in joints, entheses or the spine in the presence of skin and/or nail psoriasis and in the usual absence of rheumatoid factor and anti-cyclic citrullinated peptide. The evolution of psoriasis to PsA may occur in stages, although the mechanisms are unclear. In many patients, there may be little or no relationship between severity of musculoskeletal inflammation and severity of skin or nail psoriasis. The reason for this disease heterogeneity may be explained by differences in genotype, especially in the HLA region. New targeted therapies for PsA have been approved with additional therapies in development. These developments have substantially improved both short-term and long-term outcomes including a reduction in musculoskeletal and skin manifestations and in radiographic damage. With efforts underway aimed at improving our understanding of the molecular basis for the heterogeneity of PsA, a personalized approach to treating PsA may become possible.

Abstract
With the availability of effective treatment with targeted synthetic and biologic disease-modifying anti-rheumatic drugs (ts/bDMARDs) for psoriatic arthritis (PsA), it is crucial to identify predictors of access to this treatment since disease onset. We retrospectively enrolled patients with peripheral PsA, assessed in an early arthritis clinic from 2005 to 2020. The main baseline demographic, clinical and ultrasonographic (assessment of bilateral wrist and metacarpophalangeal joints) features were evaluated through descriptive statistics and tested as predictors by univariate and multivariate Cox models. The outcome of interest was the indication for ts/bDMARDs within 2 years from diagnosis. We included 238 patients with PsA, with a mean (sd) age of 51.04 (13.98) years; 90 (37.8%) were male, and the median (IQR) symptom duration was 6.12 (3.29–12.25) months. In univariate analyses, C-reactive protein (RR, 95% CI 1.204 (1.065,1.362)), Visual Analogue Scale (VAS) pain (1.027 (1.005,1.048)), the number of tender joints on 28 joints (1.087 (1.025, 1.153)), and a synovial power Doppler (PD) score > 1 (3.63 (1.307, 10.08)) emerged as significant predictors. C-reactive protein, VAS pain and PD confirmed their predictive value also in multivariate models. These results provide preliminary evidence on the features that might characterize patients with early peripheral PsA requiring more intensive monitoring and treatment escalation.

Abstract
Psoriasis is a symmetric autoimmune/inflammatory disease that primarily affects the skin. In a significant proportion of cases, it is accompanied by arthritis that can affect any joint, the spine, and/or include enthesitis. Psoriasis and psoriatic arthritis are multifactor disorders characterized by aberrant immune responses in genetically susceptible individuals in the presence of additional (environmental) factors, including changes in microbiota and/or epigenetic marks. Epigenetic changes can be heritable or acquired (e.g., through changes in diet/microbiota or as a response to therapeutics) and, together with genetic factors, contribute to disease expression. In psoriasis, epigenetic alterations are mainly related to cell proliferation, cytokine signaling and microbial tolerance. Understanding the complex interplay between heritable and acquired pathomechanistic factors contributing to the development and maintenance of psoriasis is crucial for the identification and validation of diagnostic and predictive biomarkers, and the introduction of individualized effective and tolerable new treatments. This review summarizes the current understanding of immune activation, genetic, and environmental factors that contribute to the pathogenesis of psoriatic arthritis. Particular focus is on the interactions between these factors to propose a multifactorial disease model.

Abstract
Psoriasis, a common skin inflammatory disorder, is characterized by the aberrant growth and differentiation of keratinocytes. Ar-Turmerone, a main bioactive ingredient of Curcuma longa, has been found to alleviate skin inflammation in psoriasis-like mice. However, the effects and underlying mechanism of ar-turmerone on keratinocytes remain unknown. The effects of ar-turmerone alone or combined with recombinant human sonic hedgehog (rhShh) on cell proliferation, apoptosis, and inflammatory cytokine secretion were explored by MTT, flow cytometry analysis, and ELISA, respectively. The mRNA and protein levels of Shh, glioblastoma-1 (Gli1), and smoothened (SMO) were determined by RT-qPCR and western blot analysis, respectively. Results disclosed that ar-turmerone dose-dependently suppressed proliferation, facilitated apoptosis, and reduced TNF-α-mediated production of interleukin (IL)-1β, IL-6, and IL-8 in HaCaT cells. Ar-turmerone blocked Hedgehog pathway in HaCaT cells, as evidenced by the reduced expression of Shh, Gli1, and SMO. Moreover, activation of the Hedgehog pathway by rhShh abolished the effects of ar-turmerone on the proliferation, apoptosis, and TNF-α-mediated inflammatory cytokine expression in HaCaT cells. In conclusion, ar-turmerone suppressed cell proliferative ability and attenuated inflammatory cytokine expression by inactivating Hedgehog pathway in HaCaT cells, contributing to better understanding the potential anti-psoriasis effects of ar-turmerone on psoriasis.

Abstract
Psoriatic arthritis (PsA) is a complex inflammatory musculoskeletal and skin disease. The treatment of PsA has changed substantially over the past 10 years. Clinical practice guidelines are developed to help busy clinicians rapidly integrate evolving knowledge of therapeutic management into practice. In this review, we compare PsA treatment recommendations or guidelines developed by one national organization [ACR and National Psoriasis Foundation (NPF) in 2018], one regional organization (EULAR in 2015), and one international organization (the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis in 2015). We examine the development of guidelines in PsA more broadly and examine similarities and differences in the three sets of recommendations.

Abstract
Background Obesity is overrepresented in patients with psoriatic arthritis (PsA) and associated with increased disease activity. We have previously shown in 41 patients with PsA (Caspar criteria) and obesity (body mass index; BMI ≥33 kg/m2) that weight loss treatment with Very Low Energy Liquid Diet (VLED), 640 kcal/day during 12–16 weeks, followed by a structured reintroduction of an energy restricted diet resulted in a median weight loss of 18.6% and concomitantly a significant improvement of the disease activity in joints, entheses and skin. The objectives of this follow-up were to study the effects of the weight loss treatment on disease activity in longer term (12 and 24 months) and to study the effects on cardiovascular risk factors. Methods The patients were assessed with 66/68 joints count, Leeds enthesitis index (LEI), body surface area, blood pressure, BMI, questionnaires and fasting blood samples at the 12- and 24-month visits. Results In total, 39 and 35 PsA patients attended the 12- and the 24-month visits, respectively. Median weight loss since baseline was 16.0% (IQR 10.5–22.4) and 7.4% (IQR 5.1–14.0) at the 12- and 24-months follow-up. The 66/68 swollen/tender joints score, LEI, CRP and HAQ score were still significantly reduced at the 12- and 24-month visits compared to baseline. The number of patients with Minimal Disease Activity increased from 28.2% (11/39) at baseline, to 38.5% (15/39; p = 0.008) and 45.7% (16/35; p = 0.016) at the 12- and 24-month visits. The weight loss was also associated with improved levels of serum lipids, glucose and urate and the antihypertensive treatment was reduced or stopped in five patients during the follow-up. Conclusions Weight loss treatment, with VLED included in the program, was associated with long-term improvement of measures of disease activity, self-reported function and markers of the metabolic syndrome after 24-months follow-up.

Abstract
BACKGROUND The efficacy and safety of certolizumab pegol over 52 weeks was compared in two groups of patients: Group 1 comprised patients naïve to biologic treatments; Group 2 comprised patients previously treated with one or more antitumor necrosis factor (TNF)-α and/or anti-interleukin (IL) agents. METHODS We reported results in 50 patients affected by both mild psoriasis (PsO) and psoriatic arthritis (PsA). Primary endpoint was a reduction from baseline at week 52 of Disease Activity Score (DAS44-ESR) in both groups of patients. Secondary endpoints were a reduction from baseline at week 52 of Psoriasis Area Severity Index (PASI), Visual Analog Scale for Pain (PAIN VAS), ESR, CRP, and Dermatology Life Quality Index (DLQI). RESULTS We observed a statistically significant improvement of both cutaneous and rheumatic disease in all patients, with a consistent reduction of DAS44-ESR, PASI, and PAIN VAS from baseline to week 52. DAS44-ESR decreased from 3.9 at BL to 1.5 at W52 (Group 1), and from 3.8 to 1.7 at W52 (Group 2). Mean PASI Score decreased from 3.2 at baseline (BL) to 0.4 at W52 (Group 1), and from 5.4 to 0.7 at W52 (Group 2). Mean PAIN-VAS decreased from a value of 73.5 at BL to 2.5 at W52 (Group 1), and from a value of 62.4 at BL to 9.2 at W52 (Group 2). We also found a reduction in ESR, CRP and DLQI values for each time point. CONCLUSIONS Our results confirm that CZP can be administered safely and effectively to treat both psoriasis and psoriatic arthritis irrespective of previous treatments with biologic agents.

Abstract
Psoriatic disease (PsD) is a heterogeneous condition that can affect peripheral and axial joints (arthritis), entheses, skin (psoriasis) and other structures. Over the past decade, considerable advances have been made both in our understanding of the pathogenesis of PsD and in the treatment of its diverse manifestations. However, several major areas of continued unmet need in the care of patients with PsD have been identified. One of these areas is the prediction of poor outcome, notably radiographic outcome in patients with psoriatic arthritis, so that stratified medicine approaches can be taken; another is predicting response to the numerous current and emerging therapies for PsD, so that precision medicine can be applied to rapidly improve clinical outcome and reduce the risk of toxicity. In order to address these needs, novel approaches, including imaging, tissue analysis and the application of proteogenomic technologies, are proposed as methodological solutions that will assist the dissection of the critical immune-metabolic pathways in this complex disease. Learning from advances made in other inflammatory diseases, it is time to address these unmet needs in a multi-centre partnership aimed at improving short-term and long-term outcomes for patients with PsD.

Abstract
Psoriasis (PsO) is one of the common chronic inflammatory skin diseases. Approximately 3% of the European Caucasian population is affected. Psoriatic arthritis (PsA) is a chronic immune-mediated disease associated with PsO characterized by distinct musculoskeletal inflammation. Due to its heterogeneous clinical manifestations (e.g., oligo- or polyarthritis, enthesitis, dactylitis, and axial inflammation), early diagnosis of PsA is often difficult and delayed. Approximately 30% of PsO patients will develop PsA. The responsible triggers for the transition from PsO only to PsA are currently unclear, and the impacts of different factors (e.g., genetic, environmental) on disease development are currently discussed. There is a high medical need, recently unmet, to specifically detect those patients with an increased risk for the development of clinically evident PsA early to initiate sufficient treatment to inhibit disease progression and avoid structural damage and loss of function or even intercept disease development. Increased neoangiogenesis and enthesial inflammation are hypothesized to be early pathological findings in PsO patients with PsA development. Different disease states describe the transition from PsO to PsA. Two of those phases are of value for early detection of PsA at-risk patients to prevent later development of PsA as changes in biomarker profiles are detectable: the subclinical phase (soluble and imaging biomarkers detectable, no clinical symptoms) and the prodromal phase (imaging biomarkers detectable, unspecific musculoskeletal symptoms such as arthralgia and fatigue). To target the unmet need for early detection of this at-risk population and to identify the subgroup of patients who will transition from PsO to PsA, imaging plays an important role in characterizing patients precisely. Imaging techniques such as ultrasound (US), magnetic resonance imaging (MRI), and computerized tomography (CT) are advanced techniques to detect sensitively inflammatory changes or changes in bone structure. With the use of these techniques, anatomic structures involved in inflammatory processes can be identified. These techniques are complemented by fluorescence optical imaging as a sensitive method for detection of changes in vascularization, especially in longitudinal measures. Moreover, high-resolution peripheral quantitative CT (HR-pQCT) and dynamic contrast-enhanced MRI (DCE-MRI) may give the advantage to identify PsA-related early characteristics in PsO patients reflecting transition phases of the disease.

Abstract
INTRODUCTION Psoriatic arthritis (PsA) is a chronic, systemic, inflammatory disease where disease burden and quality of life (QoL) are affected by both joint and skin manifestations. METHODS Patient and physician reported data were collected about 3200 patients in a cross-sectional survey of patients from nine countries. Patient-reported outcomes (PROs) included perceptions of symptom importance, EuroQol questionnaire (EQ-5D), Psoriatic Arthritis Impact of Disease (PsAID12), and Work Productivity and Activity Impairment (WPAI) Index. Outcomes were compared in patients with 'joint-only' and 'joint and skin' disease symptoms. RESULTS Of the 3200 patients, 2703 had complete information for 'joint-only' or 'joint and skin' involvement and were included in the analysis. Patients had a mean age of 49.2 years, 45.2% were female, and 64.5% had 'joint and skin' involvement. Patients with 'joint and skin' involvement had higher mean tender and swollen joint counts (5.2 and 4.8) than patients who were 'joint-only' (2.0 and 1.5). Significantly more patients with active 'joint and skin' symptoms experienced a flare (currently or within the last 12 months) compared with 'joint-only' patients (34.9 vs. 23.2%, p < 0.001). When asked to prioritize the burden of symptoms, 61.6% of patients prioritized joints, 38.4% prioritized skin. Anxiety/depression was experienced by 41.4% of patients, 62.4% of whom indicated that both joint and skin symptoms were the cause. Patients with 'joint and skin' involvement reported significantly worse QoL, work productivity and activity impairment than 'joint-only' patients (EQ-5D index 0.79 vs. 0.85, p < 0.001; EQ-5D VAS 71.98 vs. 77.68, p < 0.001; PsAID12 2.91 vs. 1.66, p < 0.001; WPAI overall work impairment 25.61 vs. 16.32, p < 0.001). CONCLUSIONS PsA patients who experience 'joint and skin' symptoms had significantly worse clinical outcomes, health-related QoL, and work productivity compared with patients with 'joint-only' symptoms.

Abstract
This review summarizes the steps from basic research on IL-17 family cytokines to understanding their role in psoriasis pathogenesis to the approval of a number of monoclonal antibodies targeting IL-17 pathways as first line treatment of psoriasis and psoriatic arthritis. The IL-17 cytokine family comprising IL-17A to IL-17F and receptor subunits IL-17RA to IL-17RE represents a genetically ancient intercellular network regulating local tissue homeostasis. Its pivotal role in antifungal defense and its central position in the pathogenesis of inflammatory diseases including psoriasis were discovered only relatively late in the early 2000s. Since the connection of dysregulated IL-17 and psoriasis pathogenesis turned out to be particularly evident, a number of monoclonal antibodies targeting IL-17 pathways have been approved and are used as first line treatment of moderate-to-severe plaque psoriasis and psoriatic arthritis, and further agents are currently in clinical development.

Abstract
Psoriasis is a common multifactorial autoimmune disease of the skin, and in a large percentage of patients, immune responses involve nail and joint pathology, which develop psoriatic arthritis (PsA). Historically, T helper 1 (Th1)-derived-IFN-γ was abundantly detected in psoriatic skin and its correlation with development and severity of PsO, led to an early classification of psoriasis as a Th1-mediated disease. Investigations of the cellular and molecular mechanisms of PsO pathogenesis in recent years, together with impressive results of biologics against interleukin 17A (IL-17) have shifted focus on IL-17A. However, the contributions of IFN-γ in IL-17 induced pathology and its involvement in the development of PsA have been largely overshadowed. This review summarizes the current knowledge on IFN-γ and provides new insights on the contribution of IFN-γ to PsO and PsA disease pathogenesis and development.

Abstract
Physicians' and patients' perspectives can vary significantly. For a long time, physicians considered psoriasis a non-pruritic dermatosis until a survey found pruritus to be the most bothersome symptom among psoriasis patients. In our study, we wanted to get an insight into the factors that affect patients and evaluate whether gender differences exist. A link of an anonymous online survey ( www.fightpsoriasis.ch ) with 24 questions was placed on the website of the Swiss Psoriasis and Vitiligo Patient Association ( www.spvg.ch ) from May 2016 until June 2017. 3164 persons participated in this online survey, of which 1979 were diagnosed with psoriasis. Significantly more females than males were affected by psoriatic pruritus [713 (36%) vs. 500 (25.3%), p ≤ 0.001] and 756 (39.7%) of all patients identified pruritus as the most life quality-limiting factor. Fewer women reported high satisfaction with their therapy compared to men [96 (4.9%) vs. 110 (5.6%), p ≤ 0.015]. Pruritus remains the most bothersome symptom and women were more often affected by it, leading to a lower treatment satisfaction among female patients.

Abstract
Background: Ocular involvement in Psoriatic Arthritis (PsA) patients is mainly associated with uveitis but there remains a paucity of data on dry eye and retinal abnormalities. We aimed to analyze dry eye and subclinical retinal abnormalities in a cohort of PsA patients sine-psoriasis (PsO). Methods: PsA patients sine-PsO were enrolled. Best-corrected-visual-acuity, ocular-surface-disease-index (OSDI), Schirmer test, tear film breakup-time, standard-automated-perimetry (SAP, mean deviation—MD, pattern standard deviation—PSD), fundus-perimetry (FP), and spectral-domain-optical-coherence-tomography (SD-OCT) were performed. Results: A total of 80 eyes from 40 PsA patients with moderate-severe disease activity, and 70 eyes from 35 healthy control (HC) were evaluated. Higher dry eye prevalence occurred in PsA than HC (p < 0.0001). ESR was positively related with OSDI (p < 0.001) and negatively related with Schirmer (p = 0.007). In PsA, SAP registered higher MD (p < 0.0001) and higher PSD (p = 0.005) in comparison with HC. PSD resulted positively correlated with ESR (p = 0.04) and CRP (p = 0.01), while MD showed a negative correlation with CRP (p = 0.01). Both FP mean differential sensitivity and mean defect were lower in PsA then HC (p < 0.0001). In PsA, FP differential sensitivity was directly related with cumulative steroids (p = 0.02). Conclusions: In PsA patients sine-PsO, dry eye and subclinical abnormalities in visual functions occurred being potentially related to systemic inflammation.

Inhibition of radiographic progression in psoriatic arthritis by adalimumab independent of the control of clinical disease activity. Rheumatology (Oxford) 2020; 58:1025-1033.

Abstract
Objectives To evaluate the relationship between radiographic progression and disease activity in subjects with PsA treated with adalimumab (ADA) or placebo (PBO) and the impact of concomitant MTX. Methods This was a post hoc analysis of the randomized, double-blind, PBO-controlled ADEPT trial. Subjects were categorized according to time-averaged (TA) disease activity (remission, low, moderate or high) based on Disease Activity Score of 28 joints with CRP [DAS28(CRP)], Disease Activity Index for Psoriatic Arthritis (DAPSA) or Psoriatic Arthritis Disease Activity Score (PASDAS), and achievement of minimal disease activity (MDA) at week 24. Radiographic progression was assessed as change in modified total Sharp score (ΔmTSS) from baseline to week 24. The analyses included interaction terms between disease activity and treatment on radiographic progression, comparison of radiographic progression in subjects categorized by disease activity and treatment, and correlation between disease activity and radiographic progression by treatment. Results The interaction terms for TA disease activity and treatment on ΔmTSS were significant (P = 0.002–0.008). Irrespective of concomitant MTX, ΔmTSS was lower with ADA vs PBO in all disease activity categories. Importantly, even in subjects having moderate or high disease activity or not achieving MDA, ΔmTSS was significantly lower on ADA than PBO (P = 0.05–0.001 for TA-DAPSA, TA-PASDAS and MDA). Correlations between TA disease activity scores and ΔmTSS were moderately positive and significant (P < 0.001) with PBO but non-significant with ADA. Conclusion Among subjects with PsA treated with ADA, there was evidence of a ‘disconnect’ between disease activity and radiographic progression: inhibition of radiographic progression was greater than expected based on control of clinical disease activity alone. MTX had no added effect. Trial registration ClinicalTrials.gov, http://clinicaltrials.gov, NCT00646386.

A set of serum markers detecting systemic inflammation in psoriatic skin, entheseal, and joint disease in the absence of C-reactive protein and its link to clinical disease manifestations. Arthritis Res Ther 2020; 22:26.

Abstract
Background C-reactive protein (CRP) is often normal in patients with psoriatic disease. Herein, we aimed to define markers of systemic inflammation in patients with monomorphic and polymorphic psoriatic skin, entheseal, and joint disease. Methods Three-step approach: (i) selection of serum markers elevated in psoriatic arthritis compared healthy controls from a panel of 10 different markers reflecting the pathophysiology of psoriatic disease; (ii) testing of these selected markers as well as C-reactive protein (CRP) in a larger cohort of 210 individuals- 105 healthy controls and 105 patients with psoriatic disease with either monomorphic skin (S), entheseal (E) or joint (A) involvement or polymorphic disease with various combinations of skin, entheseal and joint disease (SE, SA, EA, SEA); (iii) testing whether tumor necrosis factor (TNF) and interleukin (IL)-17 inhibitor therapy normalizes these markers. Results CRP was not elevated or was rarely elevated in the subgroups (S 0%, E 0%, A 20%, SE 7%, SA 33%, EA 27%, SEA 33%) despite active psoriatic disease. In sharp contrast, beta-defensin 2 and lipocalin-2 levels were elevated in the majority of patients with monomorphic skin (93% and 73%) and entheseal (both 53%), but not joint disease (27% and 20%). Conversely, elevations of calprotectin and IL-8 were found in the majority of patients with monomorphic joint disease (both 73%). IL-22 was elevated in all three monomorphic disease manifestations (S 60%, E 46%; A 60%). Furthermore, the vast majority of patients with polymorphic psoriatic disease (SE, SA, EA, SEA) showed widespread marker elevation. IL-17- and TNF inhibitor treatment significantly lowered all 5 markers of inflammation in PsA patients. Conclusions Systemic inflammation is detectable in the majority of patients with psoriatic disease, even if CRP is normal. The respective marker pattern depends on the manifestation of psoriatic disease with respect to skin, entheseal, and joint involvement.

Abstract
Objective Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis that manifests as peripheral arthritis, dactylitis, enthesitis, and spondylitis. Biologics, particularly tumor necrosis factor inhibitors (TNFis) and some interleukin 17 (IL‐17) and interleukin 23 (IL‐23) inhibitors, are the only US Food and Drug Administration (FDA)–approved treatments shown to limit joint damage in clinical trials for PsA. Conventional synthetic disease‐modifying antirheumatic drugs have also been adapted to PsA treatment. Current 2018 American College of Rheumatology (ACR) guidelines regard TNFis as first‐line therapy in treatment‐naïve patients. The aim of this project is to review the prescribing practices for patients with PsA at an urban rheumatology office, with a focus on biologic prescribing. Methods A retrospective chart review was performed to search for patients seen from June 1, 2017, to June 1, 2018, using International Classification of Diseases, 10th Revision codes for PsA. A log of prescribing practices listed the use of biologics versus oral small molecules (OSMs) (methotrexate, sulfasalazine, leflunomide, and apremilast) across different ages, sex, and disease severity. Results This study included a total of 97 patients (40 women and 57 men), and 66% were on biologics (60% of women and 70% of men). There was no sex bias in biologic prescribing (P = 0.59). Use of biologics was highest in the 38 to 57 years age group and lowest in the 78 to 97 years age group, although, statistically, there was no age bias in biologic prescribing (P = 0.22). Biologics provided superior disease control (84.37%) compared with nonbiologics (66.6%) (P = 0.0016). OSMs provided slightly better control (69.5%) over apremilast monotherapy (61.5%) (P = 0.016). Conclusion There is no age or sex bias in prescribing practices for PsA. In accordance with the ACR, patients with controlled symptoms on OSMs are being appropriately maintained. Although apremilast is allocated as an add‐on therapy, 13.4% of patients were on apremilast monotherapy. This quality improvement project reveals that in most instances, biologics are being appropriately initiated as the primary mode of therapy for patients with PsA at our outpatient practice; however, treatment modifications can be made regarding patients who are managed with apremilast alone.

Abstract
Tofacitinib is an oral Janus kinase inhibitor approved for the treatment of psoriatic arthritis (PsA). It provides an alternative option for patients who have had an inadequate response and tolerance to other disease modifying antirheumatic drugs (DMARDs). It has demonstrated comparable efficacy to biologics, is effective in the management of treatment resistant disease, and is reported to improve enthesitis, dactylitis, and radiographic progression. Tofacitinib is also associated with an increased risk of serious infections, malignancy, and laboratory abnormalities. There is currently a large armamentarium of therapies for psoriatic arthritis, and choosing among treatments can be challenging. Due to this wide selection, a thorough assessment of psoriatic disease phenotype, patient preference, disease presentation, and comorbidities is critical. This review addresses key considerations in patient selection for the treatment of PsA with tofacitinib.

Abstract
Background Psoriasis affects 1–3% of the Canadian population. Psoriatic arthritis (PsA), the most common comorbidity of psoriasis, affects up to 30% of psoriasis patients. The skin microbiome is hypothesized to play a role in the pathogenesis of psoriatic disease (PsD-psoriasis and PsA). Objective To summarize the current state of literature on the skin microbiome in PsD. Methods A systematic review was performed using searches in Ovid, Medline, Embase, Medline Epub Ahead of Print and In-Process & Other Non-Indexed Citations, and Cochrane Central Register of Controlled Trials (CENTRAL). Search was limited to humans and English language, with no limits for date or publication type. Results Of 4,032 citations identified, 9 studies met inclusion criteria (7 on psoriasis only and 2 studies compared the microbiome characteristics between psoriasis and PsA). Compared to healthy controls, lesions demonstrated a decreased alpha diversity, higher relative abundances of Firmicutes, and lower relative abundances of Actinobacteria. Less conclusive were genus-level results, which nonetheless demonstrated trends towards increased Streptococcus, Staphylococcus, and Corynebacterium and decreased Propionibacterium in lesions vs. control. Limitations Study designs were heterogeneous, including sampling technique and exclusion criteria. Conclusions Phyla- and selected genus-level characteristic of the psoriatic microbiome are presented; further research is warranted. Psoriatic lesion demonstrates decreased alpha diversity compared to healthy skin. Relative abundance of Firmicutes is higher in psoriatic compared to healthy skin. Relative abundance of Actinobacteria is lower in psoriatic compared to healthy skin. Studies vary in methodology, including sampling technique and exclusion criteria.

Abstract
BACKGROUND A specific subset of psoriasis patients is characterized by subclinical inflammatory changes. These patients frequently present with arthralgia and have a higher risk to develop psoriatic arthritis (PsA). We hypothesized that IL-17A inhibition in this subset of patients can intercept the link between skin and joint disease and resolves pain and inflammatory changes. METHODS Psoriasis, but no PsA, patients were included in the open prospective exploratory Interception in very early PsA (IVEPSA) study. Patients had to have nail or scalp involvement or a high psoriasis area severity index (PASI) (> 6) as well as inflammatory or erosive changes in MRI or CT. Patients received treatment with the anti-interleukin (IL)-17A antibody secukinumab over 24 weeks. Clinical assessments of skin and joint disease were done at baseline and after 12 and 24 weeks, MRI and CT at baseline and after 24 weeks. RESULTS Twenty patients were included, 85% of them reporting arthralgia and 40% had tender joints at the examination. Eighty-three percent had at least one inflammatory lesion in the MRI, most of them synovitis/enthesitis. Skin disease (PASI: p < 0.002; BSA: p < 0.003) and arthralgia (VAS pain: p < 0.003) significantly improved after 24 weeks. Total PsAMRIS (p = 0.005) and synovitis subscore (p = 0.008) also significantly improved. Erosions and enthesiophytes did not progress, while bone mass in the distal radius significantly (p = 0.020) increased after 24 weeks. CONCLUSIONS These data suggest that very early disease interception in PsA is possible leading to a comprehensive decline in skin symptoms, pain, and subclinical inflammation. IVEPSA therefore provides rationale for future early interventions with the concept to prevent the onset of PsA in high-risk individuals.

Safety and efficacy of ixekizumab in patients with PsA and previous inadequate response to TNF inhibitors: week 52 results from SPIRIT-P2. Rheumatology (Oxford) 2019; 57:2001-2011. [PMID: 30053162 PMCID: PMC6199530 DOI: 10.1093/rheumatology/key182] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2018] [Indexed: 01/05/2023] Open
Abstract
Objectives To assess the long-term safety and efficacy of ixekizumab, an IL-17A antagonist, in patients with active PsA. Methods In SPIRIT-P2 (NCT02349295), patients (n = 363) with previous inadequate response to TNF inhibitors entered the double-blind period (weeks 0-24) and received placebo or ixekizumab 80 mg every 4 weeks (IXEQ4W) or every 2 weeks (IXEQ2W) following a 160-mg starting dose at week 0. During the extension period (weeks 24-156), patients maintained their original ixekizumab dose, and placebo patients received IXEQ4W or IXEQ2W (1:1). We present the accumulated safety findings (week 24 up to 156) at the time of this analysis for patients who entered the extension period (n = 310). Exposure-adjusted incidence rates (IRs) per 100 patient years are presented. ACR responses are presented on an intent-to-treat basis using non-responder imputation up to week 52. Results From week 24 up to 156 (with 228 patient years of ixekizumab exposure), 140 [61.3 IR] and 15 (6.6 IR) patients reported infections and serious adverse events, respectively. Serious adverse events included one death and four serious infections. In all patients initially treated with IXEQ4W and IXEQ2W at week 0 (non-responder imputation), ACR20 (61 and 51%), ACR50 (42 and 33%) and ACR70 (26 and 18%) responses persisted out to week 52. Placebo patients re-randomized to ixekizumab demonstrated efficacy as measured by ACR responses at week 52. Conclusion During the extension period, the overall safety profile of ixekizumab remained consistent with that observed with the double-blind period, and clinical improvements persisted up to 1 year.

Efficacy and Metabolic Effect on Serum Lipids of Apremilast in Psoriatic Arthritis: A Case Report. J Clin Med 2019; 8:jcm8030398. [PMID: 30909370 PMCID: PMC6463257 DOI: 10.3390/jcm8030398] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Revised: 03/13/2019] [Accepted: 03/18/2019] [Indexed: 01/14/2023] Open
Abstract
Psoriatic arthritis (PsA) is a chronic immune-mediated disease manifesting as joint inflammation with functional impairment associated with psoriasis. Recently, PsA has emerged as a systemic disease with several comorbidities, such as cardiovascular diseases and metabolic disorders. Apremilast is a targeted synthetic disease-modifying anti-rheumatic drug (tsDMARD) directed against phosphodiesterase 4 (PDE4) with demonstrated efficacy and safety in PsA and psoriasis. We report the case of a patient with PsA manifesting as arthritis, dactylitis, mild psoriasis and a significantly reduced health-related quality of life (HRQoL). Treatment with apremilast in association with methotrexate led to a quick improvement of joint and skin involvement with a stable amelioration of HRQoL. Furthermore, we observed a persistent favorable shift of serum lipid profile. Our observations suggest that apremilast is effective in controlling mild skin and joint involvement, including dactylitis, and suggest a potentially advantageous metabolic effect in patients with PsA.

Abstract
Tofacitinib (Xeljanz®) is the first Janus kinase (JAK) inhibitor approved at a dosage of 5 mg twice daily (BID) in the EU and the USA for the treatment of active psoriatic arthritis (PsA), where it is indicated in combination with methotrexate for patients who have had an inadequate response or who have been intolerant to a prior therapy with a disease-modifying antirheumatic drug (DMARD). Two well-designed phase III trials (OPAL Broaden and OPAL Beyond) in patients with PsA with or without prior tumour necrosis factor inhibitor (TNFi) therapy showed that tofacitinib 5 mg BID (co-administered with methotrexate or another approved conventional synthetic DMARD) significantly improved the key clinical signs/symptoms and disability associated with PsA after 3 months of treatment, while also improving skin psoriasis, enthesitis, dactylitis, physical function and fatigue. According to interim data, the improvements in clinical signs/symptoms were maintained for up to 30 months in the ongoing long-term extension study OPAL Balance, with minimal radiographic progression seen after 12 months' therapy in the OPAL Broaden study. Tofacitinib 5 mg BID had an acceptable tolerability profile, with low incidences of serious infections, malignancies, cardiovascular events and gastrointestinal perforations over 36 months. Changes in laboratory parameters generally remained stable over 36 months of treatment. Although further studies are required to more definitively establish its efficacy and safety, currently available evidence indicates that tofacitinib expands the treatment options available for the treatment of PsA in patients who have had an inadequate response or who have been intolerant to a prior DMARD therapy.

Abstract
It has previously been demonstrated that the self-inactivating γ-globin lentiviral vector GGHI can significantly increase fetal hemoglobin (HbF) in erythroid cells from thalassemia patients and thus improve the disease phenotype in vitro. In the present study, the GGHI vector was improved further by incorporating novel enhancer elements and also pseudotyping it with the baboon endogenous virus envelope glycoprotein BaEVRless, which efficiently and specifically targets human CD34+ cells. We evaluated the hypothesis that the newly constructed vector designated as GGHI-mB-3D would increase hCD34+ cell tropism and thus transduction efficiency at low multiplicity of infection, leading to increased transgene expression. High and stable HbF expression was demonstrated in thalassemic cells for the resulting GGHI-mB-3D/BaEVRless vector, exhibiting increased transduction efficiency compared to the original GGHI-mB-3D/VSVG vector, with a concomitant 91% mean HbF increase at a mean vector copy number per cell of 0.86 and a mean transduction efficiency of 56.4%. Transduced populations also exhibited a trend toward late erythroid, orthochromatic differentiation and reduced apoptosis, a further indication of successful gene therapy treatment. Monitoring expression of ATG5, a key link between autophagy and apoptosis, it was established that this correction correlates with a reduction of enhanced autophagy activation, a typical feature of thalassemic polychromatophilic normoblasts. This work provides novel mechanistic insights into gene therapy-mediated correction of erythropoiesis and demonstrates the beneficial role of BaEVRless envelope glycoprotein compared to VSVG pseudotyping and of the novel GGHI-mB-3D/BaEVRless lentiviral vector for enhanced thalassemia gene therapy.

Abstract
Introduction This study investigated the effectiveness of adalimumab treatment in improving Work Productivity and Activity Impairment (WPAI) in patients with psoriatic arthritis (PsA) in real-world settings in Japan. Methods This 24-week, single-arm, postmarketing surveillance study (2014–2017), conducted at 75 centers in Japan, enrolled adalimumab-naïve patients (paid workers, including part-time) meeting ClASsification criteria for Psoriatic ARthritis (CASPAR). The primary endpoint was improvement in overall work impairment (OWI) scores from baseline to week 24. Secondary endpoints included changes in WPAI-PsA (OWI, absenteeism, presenteeism, and activity impairment), Psoriasis Area and Severity Index (PASI), psoriatic arthritis screening and evaluation (PASE) scores, Disease Activity Scores in 28 joints using C-reactive protein (DAS28[CRP]), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores, Health Assessment Questionnaire-Disability Index (HAQ-DI) scores, and PASI75/90 and American College of Rheumatology (ACR) 20/50/70 rates. Results In the effectiveness population (n = 106; 72.6% men; mean ± standard deviation [SD] age, 49.3 ± 10.7 years), OWI scores significantly improved (mean ± SD change, − 25.2 ± 35.3; p < 0.0001) from baseline to week 24. Other WPAI domain scores also improved significantly. Changes in OWI were significantly correlated (p < 0.0001) with PASE (r = 0.6284), DAS28(CRP) (r = 0.6059), BASDAI (r = 0.7281), and HAQ-DI (r = 0.6161) scores and were significantly influenced by previous nonsteroidal anti-inflammatory drug use (p = 0.0142), and baseline PASE (p = 0.0098), DAS28(CRP) (p = 0.0026), HAQ-DI (p = 0.0004), and BASDAI (p < 0.0001) scores. At the last evaluation, rate (95% confidence interval) of PASI 75 and 90 (n = 100) was 58.0% (47.7–67.8) and 39.0% (29.4–49.3), respectively, and that of ACR 20, 50, and 70 (n = 58) was 86.2% (74.6–93.9), 70.7% (57.3–81.9), and 53.4% (39.9–66.7), respectively. No new safety signals were observed in the safety population (n = 148). Conclusion Adalimumab treatment improved WPAI in patients with PsA. Improvements in OWI and joint symptoms were significantly associated. Trial Registration Number ClinicalTrials.gov identifier: NCT02414633. Funding AbbVie GK and Eisai Co., Ltd.

Weight loss improves disease activity in patients with psoriatic arthritis and obesity: an interventional study. Arthritis Res Ther 2019; 21:17. [PMID: 30635024 PMCID: PMC6330463 DOI: 10.1186/s13075-019-1810-5] [Citation(s) in RCA: 60] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2018] [Accepted: 01/02/2019] [Indexed: 11/26/2022] Open
Abstract
Background Obesity is over-represented in patients with psoriatic arthritis (PsA) and associated with higher disease activity, poorer effect of treatment and increased cardiovascular morbidity. Studies on the effects of weight loss are however needed. This study aimed to prospectively study the effects of weight loss treatment with very low energy diet (VLED) on disease activity in patients with PsA (CASPAR criteria) and obesity (body mass index BMI ≥ 33 kg/m2). Methods VLED (640 kcal/day) was taken during 12–16 weeks, depending on pre-treatment BMI. Afterwards, an energy-restricted diet was gradually reintroduced. Weight loss treatment was given within a structured framework for support and medical follow-up. Treatment with conventional synthetic and/or biologic disease-modifying anti-rheumatic drugs was held constant from 3 months before, until 6 months after baseline. Patients were assessed with BMI, 66/68 joints count, Leeds enthesitis index, psoriasis body surface area (BSA), questionnaires and CRP at baseline, 3 and 6 months. Primary outcome was the percentage of patients reaching minimal disease activity (MDA) and secondary outcomes were reaching Psoriatic Arthritis Response Criteria (PsARC) and American College of Rheumatology (ACR) response criteria. Results Totally 41/46 patients completed the study, 63% women, median age 54 years (IQR 48–62). At baseline increased BMI was associated with higher disease activity and poorer function. The median weight loss was 18.7 kg (IQR 14.6–26.5) or 18.6% (IQR 14.7–26.3) of the baseline weight. A majority of the disease activity parameters improved significantly after weight loss, including 68/66 tender/swollen joints count, CRP, BSA, Leeds enthesitis index, HAQ and patient VAS for global health, pain and fatigue. A larger weight loss resulted in more improvement in a dose-response manner. The percentage of patients with MDA increased from 29 to 54%, (p = 0.002). PsARC was reached by 46.3%. The ACR 20, 50 and 70 responses were 51.2%, 34.1% and 7.3% respectively. Conclusions Short-term weight loss treatment with VLED was associated with significant positive effects on disease activity in joints, entheses and skin in patients with PsA and obesity. The study supports the hypothesis of obesity as a promotor of disease activity in PsA.

Abstract
OBJECTIVE To develop an evidence-based guideline for the pharmacologic and nonpharmacologic treatment of psoriatic arthritis (PsA), as a collaboration between the American College of Rheumatology (ACR) and the National Psoriasis Foundation (NPF). METHODS We identified critical outcomes in PsA and clinically relevant PICO (population/intervention/comparator/outcomes) questions. A Literature Review Team performed a systematic literature review to summarize evidence supporting the benefits and harms of available pharmacologic and nonpharmacologic therapies for PsA. GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology was used to rate the quality of the evidence. A voting panel, including rheumatologists, dermatologists, other health professionals, and patients, achieved consensus on the direction and the strength of the recommendations. RESULTS The guideline covers the management of active PsA in patients who are treatment-naive and those who continue to have active PsA despite treatment, and addresses the use of oral small molecules, tumor necrosis factor inhibitors, interleukin-12/23 inhibitors (IL-12/23i), IL-17 inhibitors, CTLA4-Ig (abatacept), and a JAK inhibitor (tofacitinib). We also developed recommendations for psoriatic spondylitis, predominant enthesitis, and treatment in the presence of concomitant inflammatory bowel disease, diabetes, or serious infections. We formulated recommendations for a treat-to-target strategy, vaccinations, and nonpharmacologic therapies. Six percent of the recommendations were strong and 94% conditional, indicating the importance of active discussion between the health care provider and the patient to choose the optimal treatment. CONCLUSION The 2018 ACR/NPF PsA guideline serves as a tool for health care providers and patients in the selection of appropriate therapy in common clinical scenarios. Best treatment decisions consider each individual patient situation. The guideline is not meant to be proscriptive and should not be used to limit treatment options for patients with PsA.

CONCLUSION The 2018 ACR/NPF PsA guideline serves as a tool for health care providers and patients in the selection of appropriate therapy in common clinical scenarios. Best treatment decisions consider each individual patient situation. The guideline is not meant to be proscriptive and should not be used to limit treatment options for patients with PsA.

Resolution of synovitis and arrest of catabolic and anabolic bone changes in patients with psoriatic arthritis by IL-17A blockade with secukinumab: results from the prospective PSARTROS study. Arthritis Res Ther 2018; 20:153. [PMID: 30053825 PMCID: PMC6063019 DOI: 10.1186/s13075-018-1653-5] [Citation(s) in RCA: 49] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 06/27/2018] [Indexed: 01/14/2023] Open
Abstract
Background Although the effects of interleukin-17A (IL-17A) inhibition on the signs and symptoms of psoriatic arthritis (PsA) are well defined, little is known about its impact of local inflammatory and structural changes in the joints. The PSARTROS study was designed to elucidate the effects of IL-17A inhibition on inflammation and bone changes in joints affected by PsA. Methods This was a prospective open-label study in 20 patients with active PsA receiving 24 weeks of treatment with the IL-17A inhibitor secukinumab. Magnetic resonance imaging (MRI), power Doppler ultrasound (PDUS), and high-resolution peripheral quantitative computer tomography (HR-pQCT) of the hands were performed at baseline and after 24 weeks to assess synovitis, periarticular inflammation, bone erosion, enthesiophyte formation, and bone structure. Demographic and clinical measures of joint disease (DAPSA and DAS28-ESR), skin disease (PASI and BSA), and composite measures (minimal disease activity, or MDA) were also recorded. Results Treatment with secukinumab led to significant improvement of signs and symptoms of PsA; 46% reached MDA and 52% DAPSA low disease activity. MRI synovitis (P = 0.034) and signal in PDUS (P = 0.030) significantly decreased after 24 weeks of treatment. Bone erosions in MRI and HR-pQCT and enthesiophytes in the HR-pQCT did not show any progression, and structural integrity and functional bone strength remained stable. Conclusions IL-17 inhibition by secukinumab over 24 weeks led to a significant decrease of synovial inflammation and no progression of catabolic and anabolic bone changes in the joints of patients with PsA.

Long Non-Coding RNAs Play a Role in the Pathogenesis of Psoriatic Arthritis by Regulating MicroRNAs and Genes Involved in Inflammation and Metabolic Syndrome. Front Immunol 2018; 9:1533. [PMID: 30061880 PMCID: PMC6054935 DOI: 10.3389/fimmu.2018.01533] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2018] [Accepted: 06/21/2018] [Indexed: 01/03/2023] Open
Abstract
Psoriatic arthritis (PsA) is an inflammatory arthritis, characterized by inflammation of entheses and synovium, leading to joint erosions and new bone formation. It affects 10-30% of patients with psoriasis, and has an estimated prevalence of approximately 1%. PsA is considered to be primarily an autoimmune disease, driven by autoreactive T cells directed against autoantigens present in the skin and in the joints. However, an autoinflammatory origin has recently been proposed. Long noncoding RNAs (lncRNAs) are RNAs more than 200 nucleotides in length that do not encode proteins. LncRNAs play important roles in several biological processes, including chromatin remodeling, transcription control, and post-transcriptional processing. Several studies have shown that lncRNAs are expressed in a stage-specific or lineage-specific manner in immune cells that have a role in the development, activation, and effector functions of immune cells. LncRNAs are thought to play a role in several diseases, including autoimmune disorders. Indeed, a few lncRNAs have been identified in systemic lupus erythematosus, rheumatoid arthritis, and psoriasis. Although several high-throughput studies have been performed to identify lncRNAs, their biological and pathological relevance are still unknown, and most transcriptome studies in autoimmune diseases have only assessed protein-coding transcripts. No data are currently available on lncRNAs in PsA. Therefore, by microarray analysis, we have investigated the expression profiles of more than 50,000 human lncRNAs in blood samples from PsA patients and healthy controls using Human Clariom D Affymetrix chips, suitable to detect rare and low-expressing transcripts otherwise unnoticed by common sequencing methodologies. Network analysis identified lncRNAs targeting highly connected genes in the PsA transcriptome. Such genes are involved in molecular pathways crucial for PsA pathogenesis, including immune response, glycolipid metabolism, bone remodeling, type 1 interferon, wingless related integration site, and tumor necrosis factor signaling. Selected lncRNAs were validated by RT-PCR in an expanded cohort of patients. Moreover, modulated genes belonging to meaningful pathways were validated by RT-PCR in PsA PBMCs and/or by ELISA in PsA sera. The findings indicate that lncRNAs are involved in PsA pathogenesis by regulating both microRNAs and genes and open new avenues for the identification of new biomarkers and therapeutical targets.

Abstract
Psoriatic arthritis (PsA) is an inflammatory rheumatic disorder that occurs in patients with psoriasis and predominantly affects musculoskeletal structures, skin, and nails. The etiology of PsA is not well understood but evidence supports an interplay of genetic, immunologic, and environmental factors which promote pathological bone remodeling and joint damage in PsA. Localized and systemic bone loss due to increased activity of osteoclasts is well established in PsA based on animal models and translational studies. In contrast, the mechanisms responsible for pathological bone remodeling in PsA remain enigmatic although new candidate molecules and pathways have been identified. Recent reports have revealed novel findings related to bone erosion and pathologic bone formation in PsA. Many associated risk factors and contributing molecular mechanisms have also been identified. In this review, we discuss new developments in the field, point out unresolved questions regarding the pathogenetic origins of the wide array of bone phenotypes in PsA, and discuss new directions for investigation.

Abstract
Background Psoriatic arthritis (PsA) is an inflammatory arthritis, characterized by bone erosions and new bone formation. MicroRNAs (miRNAs) are key regulators of the immune responses. Differential expression of miRNAs has been reported in several inflammatory autoimmune diseases; however, their role in PsA is not fully elucidated. We aimed to identify miRNA expression signatures associated with PsA and to investigate their potential implication in the disease pathogenesis. Methods miRNA microarray was performed in blood cells of PsA patients and healthy controls. miRNA pathway analyses were performed and the global miRNA profiling was combined with transcriptome data in PsA. Deregulation of selected miRNAs was validated by real-time PCR. Results We identified specific miRNA signatures associated with PsA patients with active disease. These miRNAs target pathways relevant in PsA, such as TNF, MAPK, and WNT signaling cascades. Network analysis revealed several miRNAs regulating highly connected genes within the PsA transcriptome. miR-126-3p was the most downregulated miRNA in active patients. Noteworthy, miR-126 overexpression induced a decreased expression of genes implicated in PsA. Conclusions This study sheds light on some epigenetic aspects of PsA identifying specific miRNAs, which may represent promising candidates as biomarkers and/or for the design of novel therapeutic strategies in PsA.

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that negatively regulate the expression of multiple protein-encoding genes at the post-transcriptional level. MicroRNAs are involved in different pathways, such as cellular proliferation and differentiation, signal transduction and inflammation, and play crucial roles in the development of several diseases, such as cancer, diabetes, and cardiovascular diseases. They have recently been recognized to play a role also in the pathogenesis of autoimmune diseases. Although the majority of studies are focused on miRNA expression profiles investigation, a growing number of studies have been investigating the role of polymorphisms in miRNA genes in the autoimmune diseases development. Indeed, polymorphisms affecting the miRNA genes can modify the set of targets they regulate or the maturation efficiency. This review is aimed to give an overview about the available studies that have investigated the association of miRNA gene polymorphisms with the susceptibility to various autoimmune diseases and to their clinical phenotypes.
