Male Fertility in Spondyloarthritis: from Clinical Issues to Cytokines Milieu. A Narrative Review.

PURPOSEOF REVIEW: Male fertility is an emergent issue that should be considered in clinical practice, when dealing with chronic inflammatory diseases in young men. As it is known, the chronic inflammation is the main pathophysiologic mechanism in some rheumatological conditions such as spondyloarthritis (SpA), Ankylosing Spondylitis (AS) and Psoriatic Arthritis (PsA). Therefore, it is paramount to be aware if these diseases could impair male fertility, both due to the inflammation or to the treatments needed: we reviewed the literature on the most relevant and recent evidence on male fertility in patients affected by SpA, AS and PsA. RECENT FINDINGS: Rheumatological inflammatory diseases (included SpA, AS and PsA) could impair the family planning in man life, especially when diagnosed at young age. Moreover, focusing on sperm quality, it seems that a link between sperm quality impairment and a higher disease activity exist. Focusing on therapies, Tumor Necrosis Factor inhibitors showed a safety profile on human male fertility in clinical studies. Recently, a prospective study and two double-blind placebo-controlled trials assessed the impact of methotrexate and Filgotinib on semen parameters, respectively, showing a safety profile of these drugs on human semen quality. However, there are no clinical data on the impact of Interleukin (IL)17 inhibitors(i), IL12-23i and IL23i. Concerning male fertility in SpA, AS and PsA, an unmet clinical need is still present and new studies are needed to understand the association between these diseases and male fertility, and the implication of the therapies used for these diseases. This narrative review provides an overview of the available data on male fertility in patients affected by SpA, AS and PsA.

Clinical Characteristics of "Severe" Peripheral Psoriatic Arthritis: A Retrospective Analysis of a Longitudinal Cohort.

INTRODUCTION: The concept of severity in a multidomain disease such as psoriatic arthritis (PsA) is still not well defined. The aim of this study was to identify the clinical characteristics of patients with severe peripheral PsA. METHODS: Retrospective analysis of a longitudinal cohort. Demographic and clinical characteristics of patients with PsA were collected at baseline and at last follow-up. We defined the severe population using the modified Composite Psoriatic Disease Activity Index (mCPDAI); which excludes ankylosing spondylitis quality of life scale). Hence, patients with a score of 3 in at least one domain were defined as having severe PsA. Clinical characteristics of patients fulfilling the definition of severe PsA were compared to those non-severe. RESULTS: We evaluated 177 patients with peripheral PsA (M/F: 98/76). Of these, 64 (36.1%) were identified as severe according to the mCPDAI criteria, at baseline. Eighteen patients (10.1%) at last follow-up still met the definition of severe PsA. At last follow-up visit, severe patients with PsA were only males (18/18, P < 0.01) and have worse outcomes in terms of disease activity, pain, function, and impact of disease. Male sex and the severity of skin involvement at baseline were factors associated with the presence of severe PsA. The agreement between the presence of severe PsA and the absence of minimal disease activity was slight [Cohen's k: 0.174 (0.084-0.264)]. CONCLUSIONS: Our study showed that severe patients with PsA had more disease activity, pain, and impact of disease than non-severe patients. Furthermore, we demonstrated that severity and disease activity are not interchangeable concepts.

Elevating the Standard of Care for Patients with Axial Spondyloarthritis: 'Calls to Action' from Rheumacensus, a Multistakeholder Pan-European Initiative.

INTRODUCTION: Several barriers to optimal care in axial spondyloarthritis (axSpA) exist, which is detrimental to patient outcomes. The Rheumacensus programme aimed to identify how the standard of care (SoC) and treatment ambition for patients with axSpA could be elevated, from the unique perspective of three key stakeholders from across Europe: patients, healthcare professionals (HCPs) and payors. METHODS: Rheumacensus followed three phases: an insights-gathering workshop to identify current unmet needs in axSpA and an area of focus, a modified Delphi process to gain consensus on improvements within the agreed area of focus, and a Consensus Council (CC) meeting to generate 'Calls to Action' (CTA) to highlight the changes needed to elevate the SoC for patients with axSpA. RESULTS: The Rheumacensus CC consisted of four patient representatives, four HCPs and four payors. All 12 members completed all three Delphi e-consultations. The shared area of focus that informed the Delphi process was patient empowerment through education on the disease and treatment options available, to enable patient involvement in management and ultimately increase treatment adherence. Four key themes emerged from the Delphi process: patient empowerment, patient knowledge, patient-HCP consultations and optimal initial treatment. These themes informed 11 overarching CTA, which demonstrate the need for a multistakeholder approach to implement a paradigm shift towards patient-centred care to elevate health outcomes in patients with axSpA. CONCLUSION: Rheumacensus identified CTA to help bridge the disparities observed in axSpA care. It is now imperative for all stakeholders to take practical steps towards addressing these CTA to elevate the SoC and treatment ambition in patients with axSpA.

Axial spondyloarthritis (axSpA) is a long-term inflammatory disease involving the spine and other joints of the body as well as where tendons and ligaments attach to bone. AxSpA is associated with a significant burden to patients which can be worsened by delays in diagnosis and poor disease management. This report is about a programme called Rheumacensus which has the overall aim of improving the standard of care (SoC) for patients with axSpA. Rheumacensus brings together the points of view of three key groups involved in the care of people with axSpA: patients, payors and healthcare professionals (HCPs) from across Europe. Together, these three groups agreed to focus on patient empowerment through education on the disease and treatment options to effectively enhance treatment adherence, as a way to raise the SoC. Through a series of exercises­to agree on the current SoC and what needs to be improved­and group discussions, four themes were established which were used by the groups to help them suggest 'Calls to action' (CTA). The CTAs were ideas of how improvements could be made or what needs to be done to improve the care patients receive. The four themes were (1) patient empowerment, (2) patient knowledge, (3) patient­HCP consultation and (4) optimal initial treatment. In total, 11 CTAs were developed across these themes that provide direction and practical next steps which patients, payors and HCPs could take to drive change and make a real difference to patients by improving their care.

Assessment of Patient-Physician Interactions in Psoriatic Arthritis: National Results of the ASSIST Study.

INTRODUCTION: An overarching principle for the management of psoriatic arthritis (PsA) is a shared decision-making process between physicians and patients. The aim of this study is to assess the patient-physician relationship in a group of patients with PsA, by using the Perceived Efficacy in Patient-Physician Interactions (PEPPI) and CollaboRATE instruments. METHODS: This is a cross-sectional multicenter study where consecutive patients with PsA were enrolled. For each patient, the main demographic, comorbid conditions, and clinical data were collected, including the assessment of disease activity, function, quality of life, and impact of disease. PEPPI and CollaboRATE questionnaires were used, respectively, to evaluate the patient's perception of the patient-physician relationship and the shared decision-making process. RESULTS: A total of 81 patients with PsA were enrolled at four centers in Italy. Overall, our patients showed a high level of confidence in obtaining needed health care, with relatively high median (IQR) values of PEPPI (20; 16-23), and a good shared decision-making process, with high median (IQR) values of CollaboRATE questionnaire (7; 6-9). PEPPI and CollaboRATE scores showed a statistically significant inverse correlation with different clinical variables such as disease duration, Leeds Enthesitis Index, PsA impact of Disease, Health Assessment Questionnaire, pain, patient's global assessment of disease activity and clinical disease activity for PsA. The presence of comorbidities did not appear to be associated with lower values of PEPPI and CollaboRATE. CONCLUSIONS: In this study, few patients with PsA were at risk of suboptimal communication with their physician. This phenomenon appeared to be primarily related to higher disease activity and burden.

The management of patients with inflammatory bowel disease-associated spondyloarthritis: Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) and Italian Society of Rheumatology (SIR) recommendations based on a pseudo-Delphi consensus.

Spondyloarthritis (SpA) is the most frequent extraintestinal manifestation in patients with inflammatory bowel diseases (IBD). When IBD and spondyloarthritis coexist, musculoskeletal and intestinal disease features should be considered when planning a therapeutic strategy. Treatment options for IBD and SpA have expanded enormously over the last few years, but randomized controlled trials with specific endpoints focused on SpA are not available in the IBD setting. To address this important clinical topic, the Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) and the Italian Society of Rheumatology (SIR) jointly planned to draw updated therapeutic recommendations for IBD-associated SpA using a pseudo-Delphi method. This document presents the official recommendations of IG-IBD and SIR on the management of IBD-associated SpA in the form of 34 statements and 4 therapeutic algorithms. It is intended to be a reference guide for gastroenterologists and rheumatologists dealing with IBD-associated SpA.

Practice pattern for the use of intravenous iloprost for the treatment of peripheral vasculopathy in systemic sclerosis: A case-control study from the Italian national multicenter "SPRING" (Systemic Sclerosis Progression InvestiGation) Registry.

Background: Intravenous iloprost has been widely used for the treatment of systemic sclerosis peripheral vasculopathy. No agreement has been found on the regimen and the dosage of intravenous iloprost in different scleroderma subset conditions. This study aimed to evaluate the modalities of intravenous iloprost administration within a large cohort of systemic sclerosis patients from the SPRING Registry and to identify any associated clinical-demographic, instrumental or therapeutic data. Patients and Methods: Data of systemic sclerosis patients treated with intravenous iloprost for at least 1 year (case group) were retrospectively analyzed, including different timing and duration of intravenous iloprost session, and compared with those of untreated patients (control group). Results: Out of 1895 analyzed patients, 937 (49%) received intravenous iloprost treatment, while 958 (51%) were assigned to the control group. Among cases, about 70% were treated every 4 weeks, 24% with an interval of more than 4 weeks, and only 6% of less than 4 weeks. Most patients receiving the treatment every 4 weeks, or less, underwent infusion cycle for 1 day only, while if it was scheduled with an interval of more than 4 weeks, a total number of 5 consecutive days of infusions was the preferred regimen. The comparison between the two groups revealed that patients treated with intravenous iloprost had a higher frequency of DUs (p < 0.001), pitting scars (p < 0.001), diffuse cutaneous involvement (p < 0.001), interstitial lung disease (p < 0.002), as well as higher rates of anti-topoisomerase I, "late" scleroderma pattern at nailfold videocapillaroscopy. These findings were confirmed by multivariate analysis. Conclusion: Our data provide a picture on the Italian use of intravenous iloprost among systemic sclerosis patients and showed that it was usually employed in patients with a more aggressive spectrum of the disease. The disparity of intravenous iloprost treatment strategies in the different centers suggests the need of a rational therapeutical approach based on the clinical characteristics of different patients' subsets.

How do patient reported outcome measures affect treatment intensification and patient satisfaction in the management of psoriatic arthritis? A cross sectional study of 503 patients.

OBJECTIVES: The ASSIST study investigated prescribing in routine psoriatic arthritis (PsA) care and whether the patient reported outcome: PsA Impact of Disease questionnaire (PsAID-12), impacted treatment. This study also assessed a range of patient and clinician factors and their relationship to PsAID-12 scoring and treatment modification. METHODS: Patients with PsA were selected across the UK and Europe between July 2021-March 2022. Patients completed the PsAID questionnaire, with the results shared with their physician. Patient characteristics, disease activity, current treatment methods, treatment strategies, medication changes and patient satisfaction scores were recorded. RESULTS: 503 patients recruited. 36.2% had changes made to treatment, 88.8% of this had treatment escalation. Overall, the mean PsAID-12 score was higher for patients with treatment escalation; the PsAID-12 score was associated with odds of treatment escalation (OR: 1.58; p< 0.0001). However, most clinicians reported PsAID-12 did not impact their decision to escalate treatment, instead supporting treatment reduction decisions. Physician's assessment of disease activity had the most statistically significant effect on likelihood of treatment escalation, (OR = 2.68, per 1-point score increase). Escalation was more likely in patients not treated with biologic therapies. Additional factors associated with treatment escalation included: patient characteristics, physician characteristics, disease activity and disease impact. CONCLUSION: This study highlights multiple factors impacting treatment decision making for individuals with PsA. PsAID-12 scoring correlates with multiple measures of disease severity and odds of treatment escalation. However, most clinicians reported the PsAID-12 did not influence treatment escalation decisions. PsAID scoring could be used to increase confidence in treatment de-escalation.

A strategy towards disentangling treatment refractory from misdiagnosed axial Spondyloarthritis.

Axial spondyloarthritis (axSpA) encompasses radiographic axial SpA (r-axSpA), formally designated as ankylosing spondylitis (AS) and non-radiographic axial SpA (nr-axSpA). The advent of MRI permitted the description of the "pre-radiographic" (nr-AxSpA) stage characterized by bone marrow oedema lesions, histologically an osteitis, not yet visible on X-rays. Most subjects with a diagnosis of nr-axSpA do not progress to r-axSpA and the risk of misdiagnosis of nr-axSpA is considerable because back pain related to malalignment, degenerative conditions or biomechanical stress including intense exercise may lead to positive MRI scans. Even when nr-axSpA or r-axSpA are accurately diagnosed only about 40-50% achieve the ASAS40 responses with licensed therapies. It is likely that spinal enthesitis/osteitis leading to structural damage and associated damage contributes to post inflammatory disc territory secondary pain responses. Things are complicated as the concept of refractory axSpA itself is not well defined since there is no gold standard test to capture the full burden of inflammatory disease and, in any event, MRI has not been systematically applied. Nevertheless, there is sufficient evidence to borrow from the refractory rheumatoid arthritis field to propose two types of refractory axial SpA- a persistent inflammatory refractory ax-SpA (PIRaxSpA) and non-inflammatory refractory ax-SpA (NIRaxSpA). Both axSpA refractoriness and misdiagnosis need careful considerations when evaluating treatment failure. The immunological basis for axSpA immunotherapeutics non-responses is still rudimentary beyond the knowledge of HLA-B27 positivity status, CRP elevation, and MRI bone oedema that represents osteitis being equated with responder status.

The assessment of the drug retention rate of secukinumab in patients with psoriatic arthritis in a real-life multicentre cohort.

OBJECTIVES: We aimed to evaluate the drug retention rate (DRR) of secukinumab, an anti-IL-17A monoclonal antibody, in patients with psoriatic arthritis (PsA) in a real-life cohort, and to assess the impact of comorbidities and patient clinical characteristics on the DRR of secukinumab. METHODS: A retrospective study of prospective followed-up patients was performed to evaluate the DRR of secukinumab on patients with PsA attending the recruiting centres between January 2016 and June 2022. RESULTS: In 207 patients with PsA, a 60-month DRR of secukinumab of 57.0% was estimated (mean time of administration of 21.5±17.1 months). Male gender, age ≥65 years, disease duration ≥5 years and ≥10 years did not influence the DRR of secukinumab. The presence of comorbidities, considering any concomitant disorder, did not affect the DRR of secukinumab. In patients with cardiometabolic multimorbidity, a trend toward a better DRR of secukinumab was recorded. In fact, patients with high blood pressure, dyslipidaemia, and type 2 diabetes showed a trend toward an improved DRR of secukinumab. Furthermore, the presence of obesity did not influence the DRR of secukinumab. Different dosages, previous bDMARDs, and concomitant therapy with csDMARDs did not influence the DRR of secukinumab. CONCLUSIONS: A cumulative 60-month DRR of secukinumab of 57.0% in patients with PsA was retrieved. The presence of cardiometabolic multimorbidity could be associated with an improved DRR of secukinumab, whereas obesity did not affect this feature in our cohort. Previous bDMARDs, concomitant csDMARDs, and different drug dosages could not influence the DRR of secukinumab over time.

Sensitivity and Specificity of Composite Indices of Remission in Male and Female Patients With Psoriatic Arthritis: A Multicenter Cross-Sectional Study of Longitudinal Cohorts.

OBJECTIVE: The aim was to evaluate the sex differences in sensitivity, specificity, positive and negative predictive values, and likelihood ratio of the outcome indices minimal disease activity (MDA), Disease Activity Score for Psoriatic Arthritis (DAPSA), and Psoriatic Arthritis Impact of Disease (PsAID) with respect to clinical remission, evaluated from both the physician and patient perspective, in a multicenter cohort of patients with PsA. METHODS: In this cross-sectional analysis of 2 longitudinal cohorts, all patients with PsA consecutively attending our rheumatology units were considered potentially eligible for the study. In all patients, a complete clinical examination was carried out. The DAPSA was calculated for each patient (DAPSA values ≤ 4 were considered as remission) and MDA was also evaluated. Patient and physician global assessment values ≤ 1 were considered as a surrogate of remission from the patient and physician perspective, respectively. RESULTS: Two hundred seventy-two patients with PsA were enrolled (mean age 55.7 [SD 12.4]; 141 male, 131 female). In both sexes, MDA had good sensitivity and specificity toward remission as assessed by the rheumatologist. Remission according to DAPSA had excellent values of specificity but lacks sensitivity in both sexes. PsAID ≤ 4 had excellent values of sensitivity but lacked specificity in both sexes. Remission defined by DAPSA values was found to be more sensitive and specific in female patients (45.4% and 100%, respectively) than in male patients (33.3% and 84.2%, respectively) with respect to physician-judged remission. CONCLUSION: The results of this study demonstrate for the first time, to our knowledge, that some differences between the 2 sexes on the different outcome indices are possible. This could be important in the clinical management of patients with PsA.

Management of psoriatic arthritis: a consensus opinion by expert rheumatologists.

Background: Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disease involving several articular and extra-articular structures. Despite the important progresses recently made in all of the aspects of this disease, its management is still burdened by unresolved issues. The aim of this exercise was to provide a set of statements that may be helpful for the management of PsA. Methods: A group of 38 Italian rheumatologists with recognized expertise in PsA selected and addressed the following four topics: "early PsA," "axial-PsA," "extra-articular manifestations and comorbidities," "therapeutic goals." Relevant articles from the literature (2016-2022) were selected by the experts based on a PubMed search. A number of statements for each topic were elaborated. Results: Ninety-four articles were selected and evaluated, 68 out of the 1,114 yielded by the literature search and 26 added by the Authors. Each of the four topic was subdivided in themes as follows: transition from psoriasis to PsA, imaging vs. CASPAR criteria in early diagnosis, early treatment for "early PsA"; axial-PsA vs. axialspondyloarthritis, diagnosis, clinical evaluation, treatment, standard radiography vs. magnetic resonance imaging for "axial PsA"; influence of inflammatory bowel disease on the therapeutic choice, cardiovascular comorbidity, bone damage, risk of infection for "comorbidities and extra-articular manifestations"; target and tools, treat-to-target strategy, role of imaging for "therapeutic goals." The final document consisted of 49 statements. Discussion: The final product of this exercise is a set of statements concerning the main issues of PsA management offering an expert opinion for some unmet needs of this complex disease.

18F-FDG PET/CT technology for the assessment of brown adipose tissue: an updated review.

INTRODUCTION: This review provides an update of 18 F-fluorodeoxyglucose ([18F] FDG) for Brown adipose tissue (BAT) activity quantification, whose role is not completely understood. AREAS COVERED: We conducted an unstructured search of the literature for any studies employing the [18F] FDG PET in BAT assessment. We explored BAT quantification both in healthy individuals and in different pathologies, after cold exposure and as a metabolic biomarker. The assessment of possible BAT modulators by using [18F] FDG PET is shown. Further PET tracers and novel developments for BAT assessments are also described. EXPERT OPINION: Further PET tracers and imaging modalities are under investigation, but the [18F] FDG PET is currently the method of choice for the evaluation of BAT and further multicentric trials are needed for a better understanding of the BAT physiopathology, also after cold stimuli. The modulation of BAT activity, assessed by [18F] FDG PET imaging, seems a promising tool for the management of conditions such as obesity and type 2 diabetes. Moreover, an interesting possible correlation of BAT activation with prognostic [18F] FDG PET indices in cancer patients should be assessed with further multicentric trials.

An international multi-centre analysis of current prescribing practices and shared decision-making in psoriatic arthritis.

OBJECTIVES: Shared decision-making (SDM) is advocated to improve patient outcomes in Psoriatic arthritis (PsA). We analysed current prescribing practices and the extent of SDM in PsA across Europe. METHODS: The ASSIST study was a cross-sectional observational study of PsA patients aged ≥18 years attending face-to-face appointments between July 2021-March 2022. Patient demographics, current treatment and treatment decisions were recorded. SDM was measured by the clinician's effort to collaborate (CollaboRATE questionnaire) and patient communication confidence (PEPPI-5 tool). RESULTS: 503 patients were included from 24 centres across the UK, France, Germany, Italy and Spain. Physician- and patient-reported measures of disease activity were highest in the UK. Conventional synthetic DMARDs constituted a higher percentage of current PsA treatment in UK than continental Europe (66.4% vs 44.9%), which differed from biologic DMARDs (36.4% vs 64.4%). Implementing treatment escalation was most common in the UK. CollaboRATE and PEPPI-5 scores were high across centres. Of 31 patients with low CollaboRATE scores (<4.5), no patients with low PsAID-12 scores (<5) had treatment escalation. However, of 465 patients with CollaboRATE scores ≥4.5, 59 patients with low PsAID-12 scores received treatment escalation. CONCLUSIONS: Higher rates of treatment escalation seen in the UK may be explained by higher disease activity and a younger cohort. High levels of collaboration in face-to-face PsA consultations suggests effective implementation of the SDM approach. Our data indicate that, in patients with mild disease activity, only those with higher perceived collaboration underwent treatment escalation. Prospective studies should examine the impact of SDM on PsA patient outcomes. TRIAL REGISTRATION: clinicaltrials.gov, NCT05171270.

Impact of COVID-19 and vaccination campaign on 1,755 systemic sclerosis patients during first three years of pandemic. Possible risks for individuals with impaired immunoreactivity to vaccine, ongoing immunomodulating treatments, and disease-related lung involvement during the next pandemic phase.

Introduction: The impact of COVID-19 pandemic represents a serious challenge for 'frail' patients' populations with inflammatory autoimmune systemic diseases such as systemic sclerosis (SSc). We investigated the prevalence and severity of COVID-19, as well the effects of COVID-19 vaccination campaign in a large series of SSc patients followed for the entire period (first 38 months) of pandemic. Patients and method: This prospective survey study included 1755 unselected SSc patients (186 M, 1,569F; mean age 58.7 ± 13.4SD years, mean disease duration 8.8 ± 7.3SD years) recruited in part by telephone survey at 37 referral centers from February 2020 to April 2023. The following parameters were carefully evaluated: i. demographic, clinical, serological, and therapeutical features; ii. prevalence and severity of COVID-19; and iii. safety, immunogenicity, and efficacy of COVID-19 vaccines. Results: The prevalence of COVID-19 recorded during the whole pandemic was significantly higher compared to Italian general population (47.3 % vs 43.3 %, p < 0.000), as well the COVID-19-related mortality (1.91 % vs 0.72 %, p < 0.001). As regards the putative prognostic factors of worse outcome, COVID-19 positive patients with SSc-related interstitial lung involvement showed significantly higher percentage of COVID-19-related hospitalization compared to those without (5.85 % vs 1.73 %; p < 0.0001), as well as of mortality rate (2.01 % vs 0.4 %; p = 0.002). Over half of patients (56.3 %) received the first two plus one booster dose of vaccine; while a fourth dose was administered to 35.6 %, and only few of them (1.99 %) had five or more doses of vaccine. Of note, an impaired seroconversion was recorded in 25.6 % of individuals after the first 2 doses of vaccine, and in 8.4 % of patients also after the booster dose. Furthermore, the absence of T-cell immunoreactivity was observed in 3/7 patients tested by QuantiFERON® SARSCoV-2 Starter Set (Qiagen). The efficacy of vaccines, evaluated by comparing the COVID-19-related death rate recorded during pre- and post-vaccination pandemic periods, revealed a quite stable outcome in SSc patients (death rate from 2.54 % to 1.76 %; p = ns), despite the significant drop of mortality observed in the Italian general population (from 2.95 % to 0.29 %; p < 0.0001). Conclusions: An increased COVID-19 prevalence and mortality rate was recorded in SSc patients; moreover, the efficacy of vaccines in term of improved outcomes was less evident in SSc compared to Italian general population. This discrepancy might be explained by concomitant adverse prognostic factors: increased rate of non-responders to vaccine in SSc series, low percentage of individuals with four or more doses of vaccine, ongoing immunomodulating treatments, disease-related interstitial lung disease, and/or reduced preventive measures in the second half of pandemic. A careful monitoring of response to COVID-19 vaccines together with adequate preventive/therapeutical strategies are highly recommendable in the near course of pandemic in this frail patients' population.

Identification of the Minimal Disease Activity Domains Achieved Based on Different Treatments in Psoriatic Arthritis.

INTRODUCTION: The aim of this work is to characterize which Minimal Disease Activity (MDA) domains are mainly achieved, based on different treatments, in psoriatic arthritis (PsA) patients. Moreover, the association between MDA achievement and the different treatment groups was assessed. METHODS: We conducted a cross-sectional analysis of two longitudinal PsA groups. Inclusion criteria were: age ≥ 18 years, PsA diagnosis, stable treatment for at least 6 months. Patients were grouped depending on the therapy: group 1: Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)/cyclooxygenase 2 inhibitors (COX2i)/steroids, group 2: conventional synthetic Disease-Modifying Anti-Rheumatic Drugs (csDMARDs), group 3: Tumor Necrosis Factor α  inhibitors (TNFi), group 4: interleukin inhibitors (IL)12-23i or IL-23i, group 5: IL-17i, group 6: phosphodiesterase 4 inhibitors (PD4i). For each group, the achieved domains based on therapy were assessed. Multivariate logistic regression analysis was performed to assess the association between the treatment groups and the MDA achievement. RESULTS: A total of 220 patients were enrolled, and MDA was achieved in 45.8% of them. In all treatment groups, the first MDA domains achieved were: body surface area ≤ 3, swollen joint count ≤ 1 and Leeds Enthesitis Index ≤ 1, while MDA domains less frequently achieved were Patient Global Assessment (PtgA) ≤ 2 cm and pain on visual analogue scale ≤ 1.5 cm. The logistic regression analysis showed higher odds ratios for the achievement of the MDA in those patients in groups 3 and 4. CONCLUSIONS: In each treatment group, MDA domains less frequently achieved were PtGA and pain, suggesting that "patient-driven domains" are still an unmet need. Due to the study design and the low number of patients in some groups, it is not possible to clearly define which MDA domain was achieved or not based on treatment; however, it seems that some differences could be present. If larger and prospective studies confirm our preliminary results, we could move toward a personalized/domain treatment approach in PsA.

Proceedings of the GRAPPA 2022 Executive Retreat.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) leadership congregated for a strategic planning meeting before the 2022 GRAPPA annual meeting in New York, USA. Meeting aims were to review GRAPPA's performance in relation to its 2016 goals and identify successes and areas for further improvement, identify key GRAPPA priorities and activities for the next 5 years, and explore committee structures to best support these aims.

Triple jump for the optimal management of psoriatic arthritis: diet, sleep and exercise - a review.

Psoriatic arthritis (PsA) is a complex, multiform and chronic inflammatory disease characterised by the association of arthritis and psoriasis combined with other related conditions and comorbidities. Treatment of PsA has rapidly evolved by the introduction of new biological drugs and small molecules which allow to achieve disease remission or low disease activity in most of the patients. However, unmet treatment needs still persist for those patients with persistent disease activity or symptoms, impaired function, reduced quality of life or comorbidities. In this context, non-pharmacological approaches, including diet modifications, an adequate sleep quality and physical activity could provide additional benefits. In recent years, diet modifications, improvement of sleep quality and physical activity became an area of interest for researchers and some studies showed how a holistic non-pharmacological approach may ameliorate the quality of life of patients with PsA.The aim of this manuscript was to review the current evidence on the intriguing link and potential effects of diet, sleep and exercise in PsA patients. In particular, we reviewed the literature focusing on the possible benefits of a holistic approach to PsA patients considering lifestyle modifications.

Difficult to Treat and Refractory to Treatment in Psoriatic Arthritis.

Psoriatic arthritis (PsA) is a complex and chronic inflammatory condition in which the achievement of the best possible disease control has been proposed as the treatment target, which includes the possibility of reaching remission in all disease domains. However, due to the complexity of this multidomain disease, some patients may still have high disease activity in one or more domain and a high burden of disease, potentially leading to various treatment changes and to difficulty with the overall management. In this paper, we overview the concept of patients with difficult-to-treat PsA and the concept of patients with refractory-to-treatment PsA by providing a distinction between these two concepts and the possible implication for the management of patients with PsA.
