Outcomes In Psoriatic Arthritis Research Articles

MTHFR C677T rs1801133 and TP53 Pro72Arg rs1042522 gene variants in South African Indian and Caucasian psoriatic arthritis patients.

Methylenetetrahydrofolate reductase (MTHFR) gene is involved in homocysteine and folic acid metabolism. Tumour suppressor protein TP53 gene maintains cellular and genetic integrity. To date, no studies associated the MTHFR C677T rs1801133 and TP53 Pro72Arg rs1042522 with CRP levels and methotrexate (a folic acid antagonist) treatment outcomes in psoriatic arthritis (PsA) patients. The present study aimed to investigate whether the MTHFR rs1801133 and TP53 rs1042522 gene variants influences CRP levels and methotrexate treatment outcomes in South African Indian and Caucasian PsA patients. PsA patients (n=114) and healthy controls (n=100) were genotyped for the rs1801133 and rs1042522 using RFLP-PCR. (i) Results for rs1801133 genotyping: Caucasian patients had a higher frequency of the variant T-allele versus healthy Caucasian controls (40% versus 22%; OR=2.31, 95% CI=1.10-4.88, p=0.0379). Patients with the variant CT+TT genotypes had higher median CRP levels at baseline versus wildtype CC genotypes (11.70 (5.3-28.80) mg/mL versus 7.40 (5.00-15.05) mg/mL, p=0.0355). After 6 months of methotrexate treatment median CRP levels between genotypes reduced and remained similar. (ii) Results for rs1042522 genotyping: Indian patients had a higher frequency of the variant Arg-allele versus healthy Indian controls (42% versus 29%; OR=1.75, 95% CI=1.07-2.86, p=0.0275). In conclusion, patients with the MTHFR rs1801133 variant T-allele have elevated CRP levels, which can be ameliorated with methotrexate.

The Persistence of Biologic Therapies for Psoriatic Arthritis: A Narrative Review.

Drug persistence is a crucial measure of long-term efficacy, safety, and patient satisfaction. Lack of persistence can increase healthcare costs and morbidity and mortality rates. This review aimed to consolidate available data on drug persistence for various biological treatments used as the primary intervention for psoriatic arthritis and identify factors associated with nonpersistence. Reports indicate variable 1-year persistence rates for biologic therapies, ranging from 37% to 73%. Specifically, tumor necrosis factor inhibitors have shown fluctuating 1-year persistence rates ranging from 32% to 85%. IL-12/23 and IL-23 inhibitors demonstrate persistence rates of 25% to 89%, whereas data for IL-17 and JAK inhibitors are more limited, ranging from 51% to 77%. Factors such as female sex and a higher burden of comorbidities have been associated with an increased risk of nonpersistence, although evidence regarding other factors remains scarce. The significant variability in reported persistence rates may be attributed to differences in treatment gaps and methodologies across studies. Addressing and mitigating the factors leading to nonpersistence is essential for improving treatment outcomes in psoriatic arthritis.

A Real-World Analysis of Weather Variation on Disease Activity and Patient-Reported Outcomes in Psoriatic Arthritis.

Patients with inflammatory articular diseases, such as psoriatic arthritis (PsA), report weather changes in their symptoms. Our objective was to investigate the correlation between weather variation, disease activity (DA), and patient-reported outcomes (PROs) in patients with PsA. Hourly measurements of temperature, relative humidity, and pressure were obtained from 2015 to 2020 in Montreal (through Environment Canada) and were matched with DA and PROs of patients with PsA enrolled in Rhumadata. The differences in mean DA and PROs were examined between winter and summer. Pearson correlation coefficients were calculated between clinical profile and weather measurements. Among patients with PsA, 2665 PROs were collected for a total of 858 patients. The Clinical Disease Activity Index (P = 0.001) and Simplified Disease Activity Index (P < 0.001) were lower in winter. In summer, positive correlations were found between humidity and symptoms (using patient global assessment, fatigue, pain, C-reactive protein, Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index), whereas negative correlations between temperature and Health Assessment Questionnaire-Disability Index were reported. In winter, positive correlations were observed between temperature, fatigue, and pain. This is the first study to investigate weather variations through subjective and objective PROs matched with patients with PsA. Statistically significant differences in clinical profile were evident between winter and summer, as well as in their correlation with weather measurements. However, these distinctions lack clinical significance, suggesting a small impact on patients with PsA.

Mediterranean diet and exercise are associated with better disease control in psoriatic arthritis.

Psoriatic arthritis (PsA) is associated with obesity and other related comorbidities, which impose an additional burden on disease activity and response to treatment. We investigated the impact of Mediterranean diet, and exercise on the presentation and severity of PsA. Three hundred fifty-five patients with PsA (n = 279) and psoriasis (PsO) (n = 76) were included in a cross-sectional study. Demographic and clinical characteristics and dietary and exercise patterns were recorded. Patients were grouped into (i) high, moderate, and low Mediterranean diet adherence and (ii) high, medium, and low activity level. Levels of diet and exercise were correlated with disease activity indices. PsA patients had more comorbidities than their PsO counterparts (42.7% vs. 26.3%, p = .038). The majority showed a low exercise pattern (total = 71.3%, PsA = 72.4%, PsO = 67.1%). Approximately half (total = 44.2%, PsA = 43.4%, PsO = 47.4%) did not follow a Mediterranean diet. Disease Activity in Psoriatic Arthritis Score (DAPSA) (p = .004), tender (p = .003) and swollen (p = .015) joint counts, erythrocyte sedimentation rate (ESR) (p = .001), and Psoriasis Area and Severity Index (PASI) (p = .015) had an inverse correlation with exercise. Higher Mediterranean diet adherence was associated with reduced ESR (p = .056), PASI (p = .011), and body surface area (BSA) (p = .009) indices. After adjusting for body mass index (BMI), exercise retained its positive correlation with PsA disease activity, but diet showed significant correlation only with enthesitis (p = 0.015). Uptake of a Mediterranean diet and exercise have positive effects on PsA activity, independently of BMI. These findings support lifestyle recommendations to supplement conventional treatment for improvement in disease outcomes. Key points • Diet and lifestyle are important influencers of health-related outcomes in PsA. • In this cross-sectional study of 355 patients with psoriatic disease, we found that Med Diet and exercise improve outcomes in PsA independently of weight loss. • Our results suggest that diet and lifestyle modifications should supplement conventional medical treatments.

Impact of comorbidities on patient-reported outcomes in psoriatic arthritis: a single centre cohort study

BackgroundComorbidities are frequent in psoriatic arthritis (PsA) and may contribute to worse health-related outcomes. Patient-reported outcomes (PROs) are used to evaluate the burden of the assessed disease. The aim of this study is to evaluate the impact of comorbidities on selected PROs in PsA.MethodsAdult patients, diagnosed with PsA, based on CASPAR criteria, were included in this cross-sectional, observational study. Collected data encompassed the comorbidities and PROs (Health Assessment Questionnaire [HAQ], Multi-Dimensional Health Assessment Questionnaire [MDHAQ], 36-Item Short Form Health Survey [SF-36]). Standard statistic methods were performed for data assessment.ResultsThere were 267 participants included in the study (54.7% females). The most prevalent comorbidities were cardiovascular diseases (CVD) (29.2 %). Multimorbidity was observed in 50.2% cases and was associated with poorer results of SF-36 questionnaire, regarding bodily pain (34.7 [30.1, 39.3] vs. 47.5 [43.1, 52.0]; p<0.01), physical functioning (52.1 [47.3, 56.9] vs. 63.1 [58.9, 67.4]; p<0.01) and role physical (28.5 [21.2, 35.9] vs. 42.8 [35.2, 50.4]; p<0.01). CVD were associated with poorer MDHAQFn score (β=0.17, p<0.01), while mental disorders negatively influenced mental health (β= -0.35, p<0.01), vitality (β= -0.22, p<0.01), general health (β= -0.19, p<0.01), social functioning (β= -0.15, p=0.04) and role emotional (β= -0.30, p<0.01) dimensions of SF-36. ConclusionsMultimorbidity exerts significant impact on physical aspects of quality of life (QoL) in PsA. CVD and mental disorders adversely influence functional capacity as well as mental and social dimensions of QoL, respectively. The impact of comorbidities should be taken into account by clinicians and researchers assessing PROs.

P173 The positive utility of PSAID-12 score in remote monitoring and the impact of gender and treatment on patient reported outcomes in psoriatic arthritis

Abstract Background/Aims Psoriatic arthritis (PsA) is a chronic inflammatory disease that significantly impacts the quality of life (QOL) of patients. The PSAID-12 score reflects the impact of the PsA from the perspective of the patients. This study assessed patient reported outcomes using the PSAID-12 and evaluated the impact of gender, treatment and disease duration. Methods This study was a cross-sectional, observational study of patients with PsA meeting CASPAR critieria. Patients were recruited consecutively from clinic and completed the PSAID-12 questionnaires 14 days prior to their clinic visit digitally or by paper. Demographic and clinical data, including age, gender, disease duration, medication were collected. Disease activity was measured using the the tender/swollen joint count, patient/physician assessment and CRP. Results The total number of patients in the study was n = 225. The female:male ratio was 1.0:0.8. The mean disease duration was 27 years (range 2 months to 44 years). The mean age was 52 years (range 18 to 86 years). The number of patients on DMARDs was 89.3 % (201/225) and combined DMARDs and biologics was 26.67 % (60/ 225). The mean PSAID-12 score was 4.09 (SD 2.47). There was a positive correlation between the pre-clinic PSAID-12 score and the in-person calculated tender joint count (r = 0.58), swollen joint count (r = 0.51) and the Likert pain score (r = 0.84). All domains of the PsAID-12 score were higher in female than male (4.53 vs 3.47 respectively), Table 1. Fatigue, discomfort, and pain were the most reported score for females (mean 5.52, 5.22, 5.02 respectively) whereas for males the commonest scores were discomfort, pain and fatigue (mean 4.10, 3.88, 3.88 respectively). The fourth commonest score for both genders was the impact on work and or leisure activities (4.67 for females and 3.83 for males). In terms of disease duration, discomfort is the most common reported score for patients with a disease duration of less than 5 years (mean 5.09) whereas fatigue was the most common complaint in patients with the group of 5-10 years and &amp;gt;10 years (4.56 and 5.11 respectively). There was a lower mean score of skin problems in the biologics compared to the non-biologic group (2.78 vs 3.90). There was a trend towards lower coping, embarrassment, and social participation scores in the biologics group. Conclusion The PSAID-12 score correlated well with PsA disease activity. The impact on QOL from PsA was higher in females than males. Fatigue, pain and discomfort were the commonest symptoms and higher scores were reported in early disease, with discomfort being the highest in this group. Fatigue was more commonly reported in patients with longer disease duration. The benefits of the biologics on QOL and skin problems were seen in these patients despite their longer disease duration.

Hematological indices in psoriatic enthesopathy: relation to clinical and ultrasound evaluation

BackgroundEnthesopathy is considered a crucial aspect of assessment and outcome in psoriatic arthritis (PsA). Musculoskeletal ultrasound (MSUS) is a critical tool for accurately detecting enthesitis. Recent research focuses on identifying simple biomarkers for detecting and monitoring psoriatic enthesopathy. Red cell distribution width (RDW), mean platelet volume (MPV), and neutrophil/lymphocyte ratio (NLR) are components of a complete blood count (CBC) and are reliable bio-inflammatory markers in various rheumatic diseases.Aim of workTo measure MPV, RDW, and NLR in psoriatic enthesopathy and determine their relationship to disease activity and MSUS findings.Patients and methodsThis study focused on 30 people with psoriatic arthritis (PsA) as per CASPAR criteria, along with 20 control subjects. Enthesopathy was evaluated clinically using the Leeds Enthesitis Index (LEI). The modified Disease Activity Index of Psoriatic Arthritis (DAPSA28) was calculated, and RDW, MPV, NLR, CRP, and ESR were measured. Each enthesis in LEI was radiologically assessed using plain radiography and MSUS according to OMERACT definitions.ResultsThere was a significant relationship between clinical tenderness, the presence of enthesophytes on plain radiography, and MSUS findings at entheses sites (p < 0.001 for each). Psoriatic patients had higher levels of RDW and MPV (p < 0.001 and 0.01, respectively) than controls, with no significant differences in NLR (p = 0.189) between the two groups. RDW and MPV levels were positively correlated with the DAPSA28 score.ConclusionMonitoring PsA disease activity can be improved by considering RDW and MPV as reliable indicators and using them to screen for psoriatic enthesopathy with MSUS indices.Key points• Clinically identifying enthesitis in patients with PsA can be challenging. Imaging MSUS indices hold promise for objective analysis, but there is no consensus on which indices to use in clinical trials and daily practice.• Patients with psoriatic enthesopathy have higher RDW and MPV levels, which are positively correlated with DAPSA28 score.• RDW and MPV can be considered in the turn of improved screening of psoriatic enthesopathy with MSUS scores.

Characteristics associated with patient-reported treatment success in psoriatic arthritis.

To determine characteristics associated with patient-reported treatment success in psoriatic arthritis (PsA). Rheumatologist-diagnosed PsA patients fulfilling the CASPAR classification were recruited from a single center. PsA outcome measures included: 66/68 swollen/tender joint counts, Leeds/SPARCC dactylitis/enthesitis indices, psoriasis body surface area (BSA), and patient-reported outcomes (PROs) including PROMIS. The primary outcome was a patient-reported item: "Today, considering the level of control of your psoriatic arthritis and psoriasis, do you consider your treatment has been successful?" Descriptive and multivariate logistic regression analyses identified clinical predictors of patient-reported treatment success. Patient-reported reasons for lack of treatment success were explored. A total of 178 participants had a baseline visit. Mean (SD) CASPAR score was 3.7 (0.9), age 51.7 (13.5) years, and BMI 31.3 (7.2) kg/m2. Fifty-two percent were women, and 86.0% white. Treatment success was reported by 116/178(65%) patients in the analytic cohort. Among 76 patients who reported treatment failure, the most frequently selected reasons for lack of success were pain (n = 55, 72.4%), fatigue (n = 46, 60.5%), inflamed joints (n = 40, 52.6%), and stiffness (n = 40, 52.6%). Overall, 105 participants had complete data across variables in the logistic regression models. Patient-reported treatment success was independently associated with the 66-swollen/68-tender joint counts, psoriasis BSA, PROs (pain interference, physical function, fatigue), and TNF-inhibitor therapy, after controlling for BMI and demographics. Patient-reported treatment success in PsA may be achieved through improvement of inflammatory arthritis, psoriasis, pain, physical function, fatigue, and the use ofTNF-inhibitors. Patients reported treatment failure was most commonly due to symptoms of pain, fatigue and stiffness.

The Effect of JAK Inhibitors on Patient-Reported Outcomes in Psoriatic Arthritis.

Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects the joints and skin of patients with psoriasis. In this review we aimed to summarise the available evidence regarding the effect of Janus kinase inhibitors (JAKi) on patient-reported outcomes (PROs) when used for the management of PsA. We utilised a narrative review approach as we searched the available literature for articles to be included in our study. JAKi have been found to be effective in inducing better PRO responses compared to placebo. These findings have been consistent across various patient populations, including those with active PsA, those with an inadequate response to conventional therapies, and those with comorbidities. The evidence supporting the benefits of JAKi on PROs in PsA is compelling, demonstrating consistent improvements in pain, physical function, fatigue, and quality of life. Numerous studies have demonstrated the the efficacy of JAKi in improving PROs in patients with PsA.

Residual Disease Activity in Canadian Patients With Psoriatic Arthritis Treated With Advanced Therapies: Results From a Multiregistry Analysis (UNISON-PsA).

Although patient outcomes in psoriatic arthritis (PsA) have improved with the advent of advanced therapies, there remains a high unmet need to treat residual disease activity. The objective of the current study was to quantify residual disease activity and burden of disease in Canadian patients with PsA. This was a multiregion, observational, retrospective analysis of patient data extracted from the Rhumadata and the International Psoriasis and Arthritis Research Team (IPART) registries, analyzing deidentified data from patients who had initiated advanced therapy for the treatment of PsA between January 2010 and December 2019. The primary endpoint was the proportion of patients failing to achieve minimal disease activity (MDA) within 6 months; secondary endpoints included clinical and patient-reported burden of disease. Descriptive statistics included summaries by region, treatment class, and number of prior advanced therapies. One thousand five hundred ninety-six patients were included. The proportions of patients who failed to achieve MDA within 6 months of an advanced therapy were 64.8% in Ontario, 68.3% in Western Canada, 74.8% in Quebec, and 75% in the Atlantic/East region. Failure to achieve MDA was higher among patients receiving an IL-17i compared with a TNFi in all regions except the Atlantic/East. Between 73.2% and 78.6% of patients reported pain at 6 months, and continuing functional impairment varied from 24% in the West to 83.3% in the Atlantic/East. There is substantial burden and unmet need for improved therapies for Canadians with PsA. There is a wide regional variation in outcomes that requires further assessment.

Racial and ethnic determinants of psoriatic arthritis phenotypes and disease activity.

Individuals of racially and ethnically diverse backgrounds are underrepresented in psoriatic arthritis (PsA) research/clinical trials, despite evidence that their disease presentation, severity and course may be distinct. Here we aim to describe how race, ethnicity and other socioeconomic factors inform disease characteristics in PsA. 817 consecutive patients with PsA from a large, diverse metropolitan area, were enrolled in an observational, longitudinal registry. Demographics, medical history, medication use, and psoriatic disease phenotype and activity were all recorded and analyzed. The population was 77.4% non-Hispanic White, 2.2% Black, 7.1% Asian, and 9.9% identified as other races or multiracial, and 11.8% identified as Hispanic. Hispanic and non-White individuals had higher tender joint counts (p= 0.033) with similar swollen joint counts (p= 0.308) and medication use (p= 0.171). They also had high rates of radiographic axial disease. Hispanic individuals were significantly more likely to have higher tender joint counts (p= 0.029), higher RAPID3 scores (p= 0.004), and moderate-severe psoriasis (p= 0.010) compared with non-Hispanic White individuals. In this diverse cohort, 22.6% of patients identified as underrepresented racial and/or ethnic groups, mostly Asian or Hispanic. Despite similar swollen joint counts and medication use, non-white individuals have higher tender joint counts compared with white individuals. Phenotypically, they also were more likely to have radiographic axial involvement. These findings may reflect differences in PsA presentation, experience and outcomes in individuals of various racial and ethnic groups, which need to be taken into consideration in clinical care and research design.

Comparative Effectiveness of Bimekizumab in Psoriatic Arthritis: A Model-Based Meta-Analysis of American College of Rheumatology Response Criteria.

A model-based meta-analysis (MBMA) was conducted to compare the efficacy of bimekizumab with other psoriatic arthritis (PsA) treatment regimens using ≥ 20%/50%/70% improvements in American College of Rheumatology (ACR) criteria (ACR20/50/70) for patients with PsA. Forty-nine trials of 16 drugs were identified in the literature, comprising 21,340 patients. Trial-level covariates, including prior biologic use, concomitant methotrexate use, time since diagnosis, trial completion year, and active comparator were considered for exploratory models. The final model was selected using leave-one-out cross-validation (LOO CV) to assess predictive performance based on prespecified criteria. LOO CV was conducted for 15 trials; the final model demonstrated that 91.5% (952/1,040) of the observed treatment differences, and 96.1% of the observed ACR20/50/70 response rates were within the 95% prediction interval (PI). Median ACR50 response rates (95% PI) at week 16 in biologic-naïve patients were predicted to be 44% (40-49%) for bimekizumab 160 mg, among the highest of all treatments analyzed. Response rates for secukinumab 150 mg and risankizumab 150 mg were 28% (25-32%) and 27% (24-31%), respectively. The MBMA was also used to predict the probability of success (PoS) of potential head-to-head trials using ACR50 response as the end point with varying sample sizes: vs. secukinumab 150 mg, the PoS for bimekizumab 160 mg was 62% (N = 200) and 90% (N = 400). Versus risankizumab 150 mg, the PoS for bimekizumab 160 mg was 68% (N = 200) and 94% (N = 400). In summary, a predictive MBMA described ACR20/50/70 outcomes in PsA, allowing accurate and precise treatment comparisons and robust PoS calculations.

How Early Should We Use b/tsDMARDs in Active PsA? - Data from a 1-year Prospective Cohort in Hong Kong

Background Despite the wide availability of biologic/targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs) for treating psoriatic arthritis (PsA), there remain controversies regarding the positioning of b/tsDMARDs in the management algorithm for patients with active peripheral disease. While the European League Against Rheumatism (EULAR) recommends conventional synthetic DMARDs (csDMARDs) as the first-line treatment (1), the American College of Rheumatology (ACR) guideline takes a more aggressive approach, and suggests upfront use of b/tsDMARDs (2). The study aimed to evaluate whether earlier use of b/tsDMARDs might increase the likelihood of achieving minimal disease activity (MDA) in patients with PsA under the treat-to-target framework. Method Consecutive patients with PsA who fulfilled the CASPSA criteria with active peripheral disease were recruited in this prospective cohort study. The analysis included patients who were (1) given b/tsDMARDs during the study period and (2) completed 1-year follow-up. A standardized treat-to-target strategy was adopted. Patients were categorized into csDMARDs-naïve group, single-csDMARD-inadequate response (IR) group and multiple-csDMARDs-IR group. The rate of achieving MDA at the end of one year was compared. Result A total of 100 PsA patients were recruited and 27 patients (mean age: 51± 13, 15 [68%] male, disease duration: 5.6± 6.9 years) were included in the analysis. At baseline, all patients exhibited moderate to high disease activity. Prior to initiating b/tsDMARDs, 4 patients were csDMARDs-naïve, 10 patients had failed 1 csDMARD and 13 patients had failed 2 or more csDMARDs. There was no significant difference between clinical features and disease activity among the 3 groups at baseline (Table 1). Within the study period, 3 (11%) and 24 (89%) patients were given anti-TNF and anti-IL-17 agents respectively. After 1-year, there was substantial improvement in disease activity in the whole cohort (Disease Activity in Psoriatic Arthritis [DAPSA]: 22.7 at baseline vs 9.0 at 1-year, p=0.039), and 17(63%) patients achieved MDA. A differential MDA achievement rate was observed across different groups. All csDMARDs-naïve patients achieved MDA, compared to 70% in the single-csDMARD-IR and 46.2% in the multiple-csDMARDs-IR groups (p=0.046) (Figure 1). There was also a trend of better DAPSA response at one-year in the csDMARDs-naïve group (4.9± 1.6 vs 10.2± 11.8 [single-csDMARD-IR] and 9.4± 8.1 [multiple-csDMARDs-IR]). Conclusion A lower MDA achievement rate was observed in b/tsDMARDs users with prior csDMARD exposure. Earlier initiation of b/tsDMARDs might improve treatment outcome in PsA.

The protocol of a clinical effectiveness trial comparing standard step-up care, early combination DMARD therapy and early use of TNF inhibitors for the treatment of moderate to severe psoriatic arthritis: the 3-arm parallel group SPEED randomized controlled trial.

The aim of the Severe Psoriatic arthritis - Early intervEntion to control Disease trial is to compare outcomes in psoriatic arthritis (PsA) patients with poor prognostic factors treated with standard step-up conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), combination csDMARDs or a course of early biologics. This multicentre UK trial was embedded within the MONITOR-PsA cohort, which uses a trial within cohort design. Patients with newly diagnosed PsA and at least one poor prognostic factor (polyarthritis, C-reactive protein >5 mg/dL, health assessment questionnaire >1, radiographic erosions) were randomized equally and open-label to either standard care with 'step-up' csDMARD therapy, initial therapy with combination csDMARDs (methotrexate with either sulfasalazine or leflunomide) or to early biologics induction therapy (adalimumab plus methotrexate). The primary outcome is the PsA disease activity score at week 24. Ethical approval for the study was granted by the South Central Research Ethics Committee (ref 18/SC/0107). Treatment recommendations for PsA suggest more intensive therapy for those with poor prognostic factors but there are no studies that have previously used prognostic factors to guide therapy. Applying initial intensive therapy has shown improved outcomes in other inflammatory arthritides but has never been tried in PsA. Combination csDMARDs have shown some superiority over single therapies but there are limited data and concerns about side effects. Early use of biologics has also been shown to be superior to methotrexate but these drugs are costly and not usually funded first line. However, if a short course of biologics can rapidly suppress inflammation allowing treatment to be withdrawn and response maintained on methotrexate, this may be a cost-effective model for early use.

Upadacitinib Efficacy for the Treatment of Concomitant Psoriasis and Alopecia Areata

Upadacitinib is a selective JAK-1 inhibitor initially approved for the treatment of rheumatoid arthritis and recently psoriatic arthritis (PsA). We present a patient with Atopic Dermatitis (AD), Psoriasis (PsO), PsA and Alopecia Areata (AA) refractory to multiple agents however, successfully treated with upadacitinib. Our patient initially presented with refractory PsO and PsA, leading to treatment with ixekizumab. However, subsequent development of pruritic, erythematous scaly lesions, along with AA, prompted a shift to dupilumab. When distressing PsA and suboptimal outcomes with previous treatments persisted, prior biologics were discontinued and upadacitinib was initiated. Over a three-month period, the patient achieved complete clearance of PsO, significant improvement in AA and resolution of her PsA and AD. This report highlights the therapeutic benefits of upadacitinib in treating inflammatory cutaneous conditions like AA and PsO and further suggests a need for clinical trials to explore its broad therapeutic spectrum.

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

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. 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). 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. 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. clinicaltrials.gov, NCT05171270.

Molecular Background and Clinical Implications of Glucose Disorders in Patients with Psoriatic Arthritis.

Psoriatic arthritis (PsA) is an inflammatory musculoskeletal disease characterized by joint and entheses involvement. This condition is often associated with an increased prevalence of obesity, encompassing more than one-third of all patients. Given the presence of metabolic disorders, it becomes crucial to enhance clinical oversight of metabolic parameters. An early diagnosis of glucose irregularities in PsA allows for the assessment of an effective treatment strategy. The approach proves valuable in preventing the development of insulin resistance (IR) or diabetes mellitus type 2 (DMt2). Similar pathways characterize the pathomechanism of PsA and DMt2, offering an innovative perspective on treatment management. The cytokines and adipokines synthesized in the course of PsA significantly impact the development process of IR and DMt2 in different mechanisms of action. Conversely, glucose disorders influence the activity of PsA and therapy outcomes. Given the chronic inflammatory background shared by PsA, obesity, and DMt2, it is evident that inadequate management of any of the mentioned conditions can exacerbate the others. Thus, when PsA coincides with DMt2, a comprehensive multidimensional approach is necessary. This includes an effective immunosuppressive regimen complemented by appropriate anti-diabetic and insulin therapies. Moreover, often overlooked recommendations concerning overall well-being and lifestyle adjustments hold significance. This manuscript explores the connections and the relationship between the molecular background of PsA and glucose disorders. It provides a detailed exposition of specific therapeutic approaches for both conditions.

Psoriatic arthritis: improvement in outcomes but persistent sex difference – 5-year follow-up study of a Norwegian outpatient clinic population

Objective This study aimed to explore long-term changes in disease activity and remission rates, and potential sex-related differences in these outcomes, in psoriatic arthritis (PsA) patients treated in an outpatient clinic. Method This prospective longitudinal cohort study included 114 patients. The Disease Activity Index for Psoriatic Arthritis (DAPSA), clinical DAPSA (cDAPSA), 28-joint Disease Activity Score (DAS28), Simplified and Clinical Disease Activity Indices (SDAI, CDAI), Boolean remission for PsA, and minimal and very low disease activities (MDA, VLDA) were assessed. For group characteristics, parametric statistics and linear regression were used. Results At 5 year follow-up, improvement was noted for multiple measures reflecting disease activity and patient-reported outcomes. Statistically significant increases in remission rates were observed using DAS28 (+21.2%), CDAI (+9.7%), and cDAPSA (+7.6%), but not SDAI, DAPSA, Boolean remission, MDA, or VLDA. During the study period, the proportion of patients treated with biological disease-modifying anti-rheumatic drugs (bDMARDs) increased from 37.7% to 48.3% (p = 0.007). At baseline, women reported higher pain and fatigue, and had higher tender joint counts, DAPSA, cDAPSA, SDAI, CDAI, and DAS28 than men. Despite higher mean baseline C-reactive protein, men more often achieved remission, regardless of the definition applied. A higher proportion of men than women was treated with bDMARDs (baseline: 46.6% vs 28.6%; follow-up: 58.6% vs 33.9%). Conclusion This study adds evidence supporting recent improvements in PsA outcomes. Women had higher disease activity and were less likely to achieve remission than men. Despite progress in achieving remission goals, there is still room for improvement in therapeutic approaches for PsA patients.

The Psoriatic Arthritis Experience in Saudi Arabia from the Rheumatolo-gist and Patient Perspectives.

Psoriatic arthritis (PsA) is a musculoskeletal disease that adversely affects physical mobility and quality of life. It is challenging to manage because of the heterogeneous na-ture of the symptoms and the current treatment options. To explore the patient and rheumatologist perspectives of PsA to help improve understanding of the disease experience and improve disease management. A descriptive, observational cross-sectional study of Saudi Arabian dermatologists and rheumatologists and patients with psoriasis or PsA was conducted. Questionnaire data were collect-ed from 31 dermatologists, 34 rheumatologists, 90 patients with psoriasis, and 98 patients with PsA and analysed using descriptive statistics. Here, data from rheumatologists and patients with PsA are presented. The results revealed similarities and differences in the rheumatologist and patient perspec-tives of PsA. Rheumatologists and patients agreed on the impact that PsA had on patients' quality of life and that more education was needed. However, they differed on several aspects of disease man-agement. Rheumatologists estimated the time to diagnosis as four times shorter than what patients experienced. Patients accepted their diagnosis more than rheumatologists perceived them to; rheu-matologists perceived patients to be worried or fearful. Patients perceived joint pain as their most severe symptom, in contrast to rheumatologists, who presumed skin appearance was the most severe symptom. Reported input into PsA treatment goals differed significantly. More than half of the rheumatologists reported equal patient-physician input into goal development as opposed to <10% of patients reporting the same. Almost half of patients reported no input into the development of their treatment goals. The management of PsA could benefit from enhanced screening and re-evaluation of what PsA outcomes have the most value to patients and rheumatologists. A multidisciplinary ap-proach is recommended with increased patient involvement in disease management and individual-ized treatment options.

Paradoxical Effects of Depression on Psoriatic Arthritis Outcomes in a Combined Psoriasis-Psoriatic Arthritis Center.

Psoriatic arthritis (PsA) is a chronic, inflammatory arthritis that, when left untreated, can lead to erosions, deformities and decrease in quality of life. PsA is known to be associated with multiple comorbidities, including cardiovascular, metabolic and mental health syndromes, all of which can increase its overall morbidity and mortality. To characterize a cohort of patients with PsA and understand the impact of depression on PsA outcome measures. 527 consecutive patients with PsA were enrolled in an observational, longitudinal registry that followed them prospectively at standard of care visits. Demographics, medical history, medication use, and clinical exam were all recorded. Depression was reported in 22.8% of the population, anxiety in 18%, and attention deficit hyperactivity disorder in 4%. Depression was more common in female participants (P < .001). At baseline, individuals with PsA and concomitant depression had similar tender and swollen joint counts and RAPID3 compared to those without depression, and had lower body surface area affected by psoriasis (P = .04). At year one, all patients had improvement in clinical outcomes. However, patients with depression had a significantly higher tender joint count compared to those without depression (P = .001), despite similar swollen joint count and body surface area. In patients with depression, there is a discrepancy between improvement in physician assessed measures and patient reported outcomes. These observations underscore the importance of addressing depression and psychological distress as part of PsA treatment outcomes and points towards the need to address residual pain through co-adjuvant approaches.
