Matching-Adjusted Indirect Comparison of Risankizumab Versus Deucravacitinib in Patients with Moderate-to-Severe Plaque Psoriasis.

Despite advancements in the treatment of psoriasis (PsO), there are few head-to-head studies assessing comparative effectiveness of the newest therapies approved to treat PsO. Our objective was to assess the comparative clinical effectiveness of risankizumab and deucravacitinib in patients with moderate-to-severe PsO. This placebo-anchored matching-adjusted indirect comparison (MAIC) analysis utilized data from UltIMMa-1/2 risankizumab and POETYK PSO-1/2 deucravacitinib trials. Individual patient data from UltiMMA-1/2 were weighted via propensity score to match POETYK PSO-1/2 published summary data. Rate differences between risankizumab and deucravacitinib were assessed for Psoriasis Area and Severity Index (PASI) 75/90/100, the Static Physician Global Assessment (sPGA = 0 or 0/1), and the Dermatology Life Quality Index (DLQI) 0/1. At 16weeks, risankizumab-treated patients demonstrated statistically significantly higher rates of skin clearance and greater improvement in quality of life (QoL) compared to those treated with deucravacitinib. Across all outcomes, risankizumab demonstrated a lower number needed to treat compared to deucravacitinib. Limitations are potential bias due to unobserved/unmeasurable differences and limited generalizability of the results. This indirect comparison demonstrates that risankizumab has higher rates of skin clearance and greater improvements in QoL than deucravacitinib. This study will help inform healthcare providers in their treatment and management strategy of PsO.

Contributors to Organ Damage in Childhood Lupus: Corticosteroid Use and Disease Activity.

Awareness of paediatric-specific predictors of damage in Childhood-lupus is needed to inform mitigation measures. To ascertain how clinical and demographic variables correlate with damage accrual and identify predictors of damage. Analysis included UK JSLE Cohort Study participants. Univariable and multivariable Prentice-Williams-Peterson models investigated how demographic and clinical factors influenced hazards of new damage. Analyses were performed across the entire cohort, in patients with minimal disease activity marked by a time-adjusted average SLEDAI-2K score (AMS)≤2, low activity (AMS ≤ 4), moderate-high activity (AMS > 4) and those with no corticosteroids. Within the entire cohort (n = 430), factors associated with damage included: any methylprednisolone (Hazard Ratio, HR 2.20, [CI 1.33-3.62]), time-adjusted mean Physicians Global Assessment (PGA) (HR 2.87, [CI 1.48-5.56]) and AMS score (HR 1.13, [CI 1.03-1.24], all p< 0.05). Within the low activity subgroup, any methylprednisolone (HR 2.61, [CI 1.04-6.53]) and time-adjusted mean PGA (HR 3.41, [CI 1.52-7.76]) were associated with damage (both p< 0.05). Within the moderate-high activity subgroup, any methylprednisolone (HR 2.29, [CI 1.31-4.00]), time-adjusted mean PGA (HR 2.66, [CI 1.20-5.87]) and AMS score (HR 1.15, [CI 1.03-1.29]), were predictive of damage (all p< 0.05). Baseline organ damage was predictive of subsequent damage accrual in the minimal activity (HR 1.33, CI [1.78-8.08]) and no corticosteroids subgroups (HR 3.64, CI [1.83-7.24], both p< 0.005). Disease activity levels (AMS/PGA) and proxy indicators (methylprednisolone exposure, baseline damage) were found to be key predictors of damage accrual. This highlights the importance of practical strategies, to reduce disease activity and long-term treatment toxicity, such as treat-to-target.

Deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, in patients from China mainland, Taiwan, and South Korea with moderate to severe plaque psoriasis: a phase 3 randomized clinical trial.

Deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, is approved in the United States, European Union, Japan, South Korea, China, and other countries for treatment of moderate-to-severe plaque psoriasis. To evaluate the efficacy and safety of deucravacitinib in Asian patients with moderate to severe plaque psoriasis. In the 52-week, blinded, phase 3 POETYK PSO-3 trial (NCT04167462), patients were randomized 1 : 2 to placebo (n = 74) or deucravacitinib 6 mg once daily (n = 146) for 16 weeks followed by deucravacitinib alone. Coprimary endpoints were achievement of ≥ 75% reduction from baseline in Psoriasis Area and Severity Index (PASI 75) and static Physician Global Assessment score of 0 (clear) or 1 (almost clear) (sPGA 0/1) at Week 16. Efficacy and safety were evaluated throughout. At Week 16, significantly higher proportions of patients receiving deucravacitinib versus placebo achieved PASI 75 (68.8% vs. 8.1%; P < 0.0001) and sPGA 0/1 (55.6% vs. 6.8%; P < 0.0001). Response rates with deucravacitinib were maintained through Week 52. Common adverse events included upper respiratory tract infection and nasopharyngitis. Serious adverse event and discontinuation rates were low. Deucravacitinib was efficacious and well tolerated in Asian patients with moderate to severe plaque psoriasis.

Soluble urine activated leukocyte cell adhesion molecule is a strong predictor of lupus nephritis.

To evaluate urinary activated leucocyte cell adhesion molecule (ALCAM) and CD6 as predictors of lupus nephritis (LN) progression or disease resolution across a 1-year study. Serum and urine samples from biopsy proven LN subjects (n = 122) were prospectively collected over the course of a year at 3- or 6-month intervals (weeks 0, 12, 26, and 52) across multiple study sites and assessed for soluble ALCAM and CD6 levels. Urine creatinine from the same urine sample was used to normalize the levels of urinary ALCAM and urinary CD6. Measured levels of serum and urine ALCAM and CD6 were then analyzed against disease metrics cross-sectionally and longitudinally. Cross-sectional analysis at baseline revealed that urinary ALCAM significantly correlated with urine protein creatinine ratio (UPCR), renal SLEDAI, and the Physician Global Assessment (PGA), and negatively correlated with serum C3 and C4. Receiver operating characteristic (ROC) curve analysis demonstrated that urinary ALCAM is a predictor of LN with an area under the curve (AUC) of 0.97, compared with urinary CD6 with an AUC of 0.71. Importantly, the change in urinary ALCAM over a 3-month period distinguished between non-responders and responders at week 52. Urinary ALCAM is reflective of changes in LN and may be predictive of response status.

A 3-Year Multicentric Study on Switching from Ustekinumab to Guselkumab in Partial Responders with Psoriasis-IL PSO (Italian Landscape Psoriasis).

Guselkumab, a human monoclonal antibody targeting the p19 subunit of interleukin-23 (IL-23), has shown efficacy in psoriasis and psoriatic arthritis. However, long-term real-world data on its effectiveness in patients with inadequate response to ustekinumab are limited. This study investigates guselkumab's long-term effectiveness and safety in patients with psoriasis with partial response to ustekinumab. We performed a retrospective multicentric study analyzing data of patients with psoriasis from seven Italian hospitals between January 2021 and May 2024. The study included 169 patients who switched from ustekinumab to guselkumab. Primary endpoints were Psoriasis Area and Severity Index (PASI) 75, PASI 90, PASI 100, and absolute PASI ≤ 2. Site-specific Physician Global Assessment (PGA) scores were also collected for difficult-to-treat areas. The study included 169 patients. After 3years of treatment, PASI 75, PASI 90 and PASI 100 were achieved by 88.4%, 55.8%, and 32.6% of patients, respectively. Site-specific PGA showed significant improvements, especially in the scalp and genital areas. After 3years of treatment, no significant impact of higher body mass index (BMI) or cardiometabolic comorbidities on guselkumab effectiveness was detected. No severe adverse events were reported during the study period. In our study, guselkumab provided significant long-term effectiveness and safety in patients partially responsive to ustekinumab, improving both PASI score and site-specific PGA and confirming its potential use for patients with psoriasis switching from ustekinumab.

Physical component of SF-36 is associated with measures of disease activity in patients with psoriatic arthritis: a real-life study from a tertiary referral centre.

Psoriatic arthritis (PsA) can lead to chronic disability. The aim of this study was to explore the association between disease activity and quality of life (QoL) in patients with PsA from the usual clinical practice. The study involved 143 consecutive adult patients with PsA (49.6% women and 50.4% males), with mean age of 57.75 ± 10.91 years, and duration of disease 11.6 ± 9 years. Tender (TJC) and swollen joints count (SJC), Disease activity score (DAS) 28, patient's global assessment (PtGA), physician's global assessment (PhGA), enthesitis score, number of fingers with dactylitis, sedimentation rate (ESR) and C-reactive protein (CRP) were evaluated. The functional assessment of chronic illness therapy - fatigue scale (FACIT-F) questionnaire was used in fatigue assessment and physical health domains of Short Form (SF)-36 questionnaire were chosen to assess subjective QoL: physical functioning (PF), role limitations due to physical health (RP), bodily pain (BP) and general health (GH). Significant correlations (p < 0.001) were found between FACIT-F and all SF-36 domains. DAS28, PtGA and PhGA were significantly correlated to two or three SF-36 domains, while ESR and CRP were not significantly correlated to any of SF-36 domains. Regression analysis showed, when controlling for age, that FACIT-F, dactylitis and DAS28 were the most significant predictors of SF-36 physical health domains. Regression and factor analyses confirmed that FACIT-F was most consistently associated with SF-36 physical health domains. In our real-life study most of the analyzed clinical measures of PsA were significantly associated with physical health domains of SF-36 questionnaire. Considering the strength of those associations, we conclude that PsA activity has mild to moderate impact on health-related Qol.

Efficacy of Ixekizumab in Chinese Patients with Moderate-to-Severe Psoriasis and Special Body Area Involvement: Sub-analysis of a Randomized, Double-Blind, Multicenter Phase 3 Study.

Special body area involvement is common in psoriasis and can be challenging to treat. We investigated the efficacy of ixekizumab (IXE) in Chinese patients with moderate-to-severe psoriasis and fingernail, scalp, or palmoplantar involvement. A post-hoc sub-analysis of a phase 3 trial, in which patients were randomized to receive placebo, IXE 80mg every 2 (IXE Q2W) or 4 (IXE Q4W) weeks. At Week 12, patients classified as IXE responders [static Physician's Global Assessment (sPGA) score of 0 or 1 [0,1)] were re-randomized (2:1) to IXE Q4W or placebo until Week 60. Efficacy was assessed by body-regionspecific parameters including Nail Psoriasis Severity Index (NAPSI), Psoriasis Scalp Severity Index (PSSI), and Palmoplantar Psoriasis Area Severity Index (PPASI). Of 438 patients, 99.1% (434) had≥1 special area involvement [fingernail (76.5%, 335), scalp (97.3%, 426), palmoplantar (27.9%, 122)]. Significantly greater improvements from baseline in NAPSI score were observed with IXE Q4W and Q2W at Week 12 versus placebo (p<0.001 for both). These improvements were further increased and sustained over 60weeks in IXE Q4W and Q2W responders who were re-randomized to IXE Q4W, who achieved a 77.9% and 89.7% improvement from baseline, respectively, at Week 60. Significantly higher proportions of patients receiving IXE Q4W and Q2W achieved NAPSI 50 at Week 12 versus placebo (44.4%, 36.6% vs. 14.1%; p<0.001 and<0.01, respectively). Similarly, significantly higher proportions of patients receiving IXE Q4W and Q2W achieved PSSI 100 and PPASI 100 at Week 12 versus placebo (60.6% and 65.1% vs. 1.2%, and 67.4%, 84.3% vs. 21.4%, respectively; p<0.001 for all comparisons). Improvements across all outcomes were sustained in patients re-randomized to IXE Q4W until Week 60. IXE led to a rapid onset of action and sustained efficacy over 60weeks in Chinese patients with moderate-to-severe psoriasis and special body area involvement. gov identifier, NCT03364309.

Efficacy of Alexandrite Laser in the Treatment of Pigmented Actinic Keratoses: A Pivotal Study.

Pigmented actinic keratoses (PAKs), a pigmented variant of actinic keratosis, present diagnostic challenges due to their resemblance to both benign and malignant lesions. Conventional therapies have inconsistent outcomes and may cause undesirable side effects. This study investigates the efficacy of the Alexandrite laser, a pulsed laser with selective melanin absorption, for PAK treatment. Through dermoscopic analysis pretreatment, it aims to identify predictive patterns for better treatment outcomes. Patients with PAKs were enrolled in a multicenter study, receiving standardized Alexandrite laser therapy. Detailed dermoscopic evaluations were conducted pretreatment. The Physician's Global Assessment (PGA) and Target Lesion Pigmentation (TLP) scales measured treatment efficacy. The study included 50 patients with 60 PAKs. Following treatment, there was a statistically significant reduction in TLP scores, particularly in lesions with pigmented pseudo-networks and gray-brownish dots, which were linked to improved outcomes. No adverse effects were reported, suggesting the safety and tolerability of the laser treatment. The Alexandrite laser emerges as a promising modality for the management of PAK pigmentation, with specific dermoscopic patterns being indicative of a favorable response. This study reinforces the critical importance of dermoscopic expertise in the selection and optimization of treatment for PAKs. Future research should focus on comparative studies with different lasers or combination therapies to develop a more comprehensive treatment framework for PAKs.

Anti-pentraxin 3 antibodies and residual disease activity in rheumatoid arthritis.

This study quantified anti-PTX3 antibodies in the serum of seropositive and seronegative rheumatoid arthritis (RA) patients, examining their associations with disease activity and patient-reported outcomes (PROMs). In this cross-sectional study, RA patients diagnosed per ACR/EULAR 2010 criteria were recruited. Seronegative RA was defined as ACPA < 7 kU/l. Data on demographics, clinical characteristics, medications, and PROMs were collected. Serum anti-PTX3 antibodies were measured using an in-house ELISA method. Comparative analyses were conducted with historical controls having psoriatic arthritis (PsA) and fibromyalgia (FM). The cohort included 83 RA patients (42 seropositive, 41 seronegative). Seropositive patients had lower anti-PTX3 antibody levels than PsA (p= 0.001) and FM (p= 0.004) controls. Seronegative patients had higher levels than seropositive ones (p= 0.032). Anti-PTX3 antibodies correlated with CDAI (r = 0.255), PtGA (r = 0.257), VAS-GH (r=-0.235), VAS-pain (r = 0.233), and HAQ (r = 0.311), but not with joint counts, inflammatory markers, or physician's global assessment. The PtGA association remained significant when adjusted for BMI, SJC28, ESR, and prednisone dosage (β = 0.206, p= 0.042). Patients with near-controlled RA (SJC28 ≤ 2, PtGA > 2) had higher anti-PTX3 levels than those with controlled disease (SJC28 ≤ 2, PtGA ≤ 2; p= 0.048). Tocilizumab or abatacept-treated patients had lower levels compared with those on TNFi or JAKi. Elevated anti-PTX3 antibodies in RA indicate residual active disease despite controlled inflammation. They may serve as a biomarker for true active disease, especially in seronegative RA patients who might be undertreated.

Responsiveness of different disease activity indices in moderate-to-severe ulcerative colitis.

Clinical, endoscopic, histological, and composite instruments are currently used to measure disease activity in patients with ulcerative colitis (UC). We compared the responsiveness of the Mayo Clinic score (MCS), modified MCS (mMS; excluding physician global assessment), partial MCS (pMS; MCS without endoscopic subscore), Robart's Histopathology Index (RHI), and UC-100 score to change after ustekinumab treatment in patients with moderately to severely active UC. Post hoc analysis of the phase 3UNIFI induction trial (ClinicalTrials.gov: NCT02407236) was conducted. Participants with moderately to severely active UC were randomized to receive ustekinumab or placebo. Treatment assignment was the criterion to assess responsiveness, which was quantified using the probability of a treated participant having a larger change in score than a placebo participant, termed the win probability (WinP), and estimated using nonparametric methods. The UC-100 score demonstrated large responsiveness (WinP 0.72 [95% confidence interval: 0.66-0.78]), and the MCS (0.68 [0.62-0.73]), mMS (0.69 [0.63-0.75]), and pMS (0.65 [0.59-0.71]) demonstrated similar effect sizes. Of the component items of the Mayo score, the endoscopic subscore (WinP 0.76 [0.69-0.82]) and the stool frequency subscore (WinP 0.74 [0.69-0.79]) were the most responsive. The Inflammatory Bowel Disease Questionnaire (IBDQ) quality-of-life questionnaire was also responsive (WinP 0.78 [0.72-0.82]). UC disease activity indices are similarly responsive. Depending on the treatment setting, time point of evaluation, and feasibility of measurement, different scores may be used to demonstrate response. These results support the use of mMS as a composite primary endpoint, incorporating both patient-reported and endoscopic outcome measures. The UC-100 score may be more appropriate in settings that also routinely incorporate histological evaluation. There is no funding for this study.

Long-term real-world data of ustekinumab in ulcerative colitis: the Stockholm Ustekinumab Study (STOCUSTE).

Ustekinumab (UST) is an anti-interleukin-12/23 antibody used in the treatment of inflammatory bowel disease. This study includes patients treated at four hospitals in Stockholm to provide long-term real-world data. Retrospective study including patients diagnosed with ulcerative colitis and treated with UST between the years 2019 and 2021. Patients were followed until withdrawal of treatment, or until a predefined end of study, 31 July 2021. Disease activity was assessed with Physician Global Assessment (PGA); Ulcerative Colitis Endoscopic Index of Severity (UCEIS), laboratory parameters, and drug persistence. The primary outcome was steroid-free remission (PGA = 0) and response (decrease PGA ≥ 1 from baseline) at 3 and 12 months, respectively. A total of 96 patients, 44 women and 52 men were included. The patients had either extensive colitis (69%), left-sided colitis (29%), or proctitis (3%). All but two patients were anti-TNF-experienced; 94 (98%) had failed ≥1, 59 (61%) ≥ 2, and 34 (35%) had failed ≥ 3 anti-TNF drugs. In addition, 28 (29%) had failed vedolizumab. At inclusion, 92/96 patients (96%) had active disease and four patients were in remission. Among patients who were treated with UST, 9/71 (13%) were in steroid-free remission at 3 months, and 26/33 (78%) were at 12 months. Withdrawal rates at 3 and 12 months, were 12 and 26%, respectively, mainly due to persisting disease activity (20%). In this group of patients with difficult-to-treat ulcerative colitis, UST was shown to be effective in the majority, with high drug persistence at 12 months in combination with a favorable safety profile.

Tofacitinib treatment for plaque psoriasis and psoriatic arthritis: A meta-analysis of randomised controlled trials.

Objectives Tofacitinib is used as an oral Janus-associated kinase (JAK) inhibitor acting on JAK1 and JAK3, in treating psoriatic disease. However, there is still no consensus on the optimal dosage and duration of tofacitinib. In this study, we aimed to evaluate the effects of tofacitinib in treating psoriatic disease. Methods and Materials A literature search was done utilising Cochrane library, Medline, EMBASE, Wiley Online library, Web of Science and BIOSIS Previews through December 18, 2022. We performed a meta-analysis of published original studies to assess the impact of tofacitinib in plaque psoriasis or psoriatic arthritis therapy based on seven randomised controlled trials (RCTs) involving 2,672 patients (receiving tofacitinib) and 853 controls (receiving placebo). Results Compared with placebo, the treatment of 5 mg twice-daily (BID) tofacitinib for 12 weeks is sufficient to significantly alleviate the main clinical manifestations of psoriasis [≥75% decrease in Psoriasis Area and Severity Index score (PASI 75): Risk ratio (RR)=4.38 (95% Confidence interval (CI) 2.51 to 7.64); ≥90% decrease in PASI score (PASI 90): RR=21.68 (95% CI 4.20 to 111.85); Physician's Global Assessment of 'clear' or 'almost clear' (PGA 0/1): RR=3.93 (95%CI 3.03 to 5.09)]. Interestingly, there was no significant difference in improvement in PGA 0/1 with 5 mg BID tofacitinib given for 16 weeks when compared with 5 mg BID tofacitinib for 12 weeks [RR=1.11 (95%CI 0.98 to 1.25)]. Additionally, the 5 mg BID tofacitinib for 16 weeks treatment schedule significantly increased the incidence of upper respiratory tract infection (URTI) [RR=1.89 (95%CI 1.06 to 3.38)] as compared to 5 mg BID tofacitinib for 12 weeks treatment schedule [RR=1.15 (95%CI 0.60 to 2.20)]. Conclusion The 5 mg BID tofacitinib for 12 weeks treatment significantly improved psoriasis without causing too many specific adverse events. This indicated that tofacitinib is an effective treatment plan for psoriatic disease by reasonably controlling dosage and dosing time.

Disease activity score for still's disease.

To develop the Still's Disease Activity Score (SDAS). We used data from the prospective adult-onset Still's disease cohort study and evaluated the disease activity. An expert group selected the most frequent, reproducible, and objective variables significantly modified in statistical analysis when comparing patients in the active group and in the remission group. These criteria were weighted to design the Still's Disease Activity Score (SDAS). The Delphi method was used to appreciate the level of disease activity. Total SDAS was calculated for each patient and compared to final consensus experts. At the diagnosis, all patients had an active disease (n = 80), while 48 patients were in remission at 6 months. The SDAS criteria were weighted as follows: fever ≥ 38.5 °C (1 point), rash (1 point), joint involvement (arthralgia: 1 point, swollen joints count "SJC": 1-3 SJC: 2 points, ≥ 4 SJC: 3 points), physician global assessment VAS ≥ 5/10 or a raise in physician VAS ≥ 2/10 (3 points), patient VAS ≥ 5 or a raise in patient VAS ≥ 2/10 (1 point), and CRP (> 10 mg/l: 1 point, ≥ 100 mg/l: 2 points). At 6 months, the consensus was achieved for 76 (95%) patients with 40 in remission (0-1 point), 8 in low disease activity (2-3 points), 16 in moderate disease activity (4-7 points), and 12 in severe disease activity (≥ 8 points). The Still's Disease Activity Score is a valid and sensitive assessment of the disease activity and the therapeutic response in Still's disease, despite its heterogeneous manifestations and patterns with systemic and articular forms. Key Points •The Still's Disease Activity Score (SDAS) is a good simple tool to assess the activity of the disease in a stable state for a week. •The SDAS is developed specifically for Still's disease without the need for an application or a calculator to calculate SDAS in routine clinical practice. •SDAS is a composite score classifying the disease activity in remission, low disease activity, moderate disease activity, and severe disease activity despite its heterogeneous patterns (systemic and articular forms). •The SDAS is a valid, reliable, and sensitive score and can be useful to guide the therapeutic strategy in clinical practice and in research.

Comparison of the Effectiveness of Platelet-Rich Plasma Versus Tranexamic Acid Plus Vitamin C Mesotherapy in the Treatment of Periorbital Hyperpigmentation: A Split-Site, Randomized Clinical Trial.

Periorbital hyperpigmentation (POH) is a common cosmetic problem with a negative impact on the patient's self-confidence, leading to a decrease in the quality of life. Current treatments include topical agents and mesotherapy, but research remains limited. Due to the undesirable effect of the available treatments, the present study was designed to compare the effectiveness of platelet-rich plasma (PRP) injection and intradermal injection of tranexamic acid plus vitamin C mesotherapy as a therapeutic method to treat POH. Patients received an intradermal injection of PRP randomly on one side and an intradermal injection of tranexamic acid + vitamin C on the other side of their face, for three sessions with an interval of 3 weeks. Digital photography was taken, and data were assessed based on physician global assessment (PGA) and patient satisfaction. Eighteen patients were studied. Among all, 12 patients had a positive family history, 2 had asthma, and 4 had a history of atopic dermatitis. Even though patient satisfaction was higher in the PRP group than in mesotherapy, it was not statistically significant. Both groups showed similar rates of improvement. However, improvement rates did not significantly differ based on various factors including gender, skin type, family history, or medical history. Age and the age of disease onset also did not significantly affect the improvement rates. Both methods revealed successful results in the reduction of POH. Comparing the efficacy of these two methods showed that both treatments had similar improvements.

Association of anti-HMGCR antibodies of the IgM isotype with refractory immune-mediated necrotizing myopathy.

Anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) autoantibodies are one of the myositis-specific antibodies which is associated with immune-mediated necrotizing myopathy (IMNM). However, the relationship between anti-HMGCR isotypes and prognosis has not yet been fully investigated. This study was conducted to gain insight into the association between anti-HMGCR isotypes and clinical, and prognosis in IMNM patients who were positive for anti-HMGCR antibodies. Levels of anti-HMGCR isotypes (IgG, IgA and IgM) were assessed by enzyme-linked immunosorbent assay (ELISA) in 123 consecutive serum samples obtained from 71 patients who were positive for anti-HMGCR IgG at baseline. Disease activity was assessed by manual muscle testing (MMT) 8, Physician's Global Assessment (PGA) visual analog scale (VAS), and muscle VAS. Baseline anti-HMGCR IgG levels were correlated with PGA VAS (r = 0.24; p = 0.04), muscle VAS (r = 0.32; p < 0.01), and MMT8(r=-0.24; p = 0.04), and baseline anti-HMGCR IgM levels were positively correlated with PGA VAS (r = 0.27, p = 0.02), muscle VAS (r = 0.24, p = 0.04). Anti-HMGCR IgM positive patients had a lower age of onset [29(25,46) vs. 51(33,65), p = 0.006], and a higher proportion of neck weakness (63.5% vs. 34.6%, p = 0.031) compared with anti-HMGCR IgM negative patients. Longitudinal analysis showed that the changes in anti-HMGCR IgG levels were correlated with the changes in the PGA VAS (β = 3.830; p < 0.0001), muscle VAS (β = 2.893; p < 0.0001), MMT8 (β=-19.368; p < 0.0001), and creatine kinase (CK) levels (β = 3900.05, p < 0.0001). Anti-HMGCR IgM levels were weakly correlated with anti-HMGCR IgA levels at baseline (r = 0.33, p < 0.01), and the variations in anti-HMGCR IgA levels were correlated with the changes in anti-HMGCR IgM levels during follow-up (β = 0.885; p < 0.0001). There were more patients with anti-HMGCR IgM who showed a refractory course than those who were with anti-HMGCR IgM negative (polycyclic course: 40% vs. 25%; chronic continuous course: 46.7% vs. 20.5%, p = 0.018). In anti-HMGCR IgG-positive IMNM patients, the levels of anti-HMGCR IgG are associated with disease activity, and anti-HMGCR IgM is associated with refractory outcome and poor prognosis.

Effect of joint hypermobility on outcomes of children with juvenile idiopathic arthritis.

Juvenile idiopathic arthritis (JIA) is common in pediatric rheumatology. Despite treatment, many patients experience persistent disease activity. Joint hypermobility (JH), defined by an excessive range of motion across multiple joints, is prevalent in children and adolescents and may influence disease outcomes in JIA. This study examines the impact of JH on symptoms in youth and young adults with JIA. Data were obtained from the PR-COIN network and included patients under 21years old with a diagnosis of JIA. Patients with JIA and JH were matched with those having JIA-only based on age, sex assigned at birth, JIA subtype, and medication exposure. Clinical data, including disease activity measures, patient well-being, and pain ratings, were collected at baseline and follow-up visits. The sample included 420 patients with JIA + JH and 2100 with JIA only. The JIA + JH group exhibited higher disease activity at baseline, more active arthritis joints, elevated physician global assessment of disease activity scores, and worse patient-reported well-being. These differences persisted over time. The JIA + JH group had a 19-20% greater likelihood of maintaining high disease activity scores and worsening over subsequent visits, indicating a significant impact of JH on disease progression. JH in youth with JIA is associated with higher and persistent disease activity, suggesting that JH significantly contributes to the disease burden in patients with JIA and should be considered in treatment strategies. Future research should further explore the mechanisms by which JH influences disease activity and investigate comprehensive management approaches to improve outcomes for this population. Key Points • Children with JIA and joint hypermobility (JH) exhibit significantly higher disease activity at baseline compared to those with JIA only, including more active arthritis joints and elevated physician global assessment scores. • The presence of JH in JIA patients is associated with poorer patient-reported well-being and higher overall disease activity scores, which persist over time despite treatment. • JIA + JH patients have a 19-20% greater likelihood of maintaining high disease activity and worsening over subsequent visits, indicating a significant impact of JH on disease progression. • The study suggests that JH should be considered an important clinical factor in the management of JIA, with targeted interventions needed to address the increased disease activity and improve overall patient outcomes.

Expert consensus on systemic therapy for plaque psoriasis with limited skin involvement in JAPAN: Results from a DELPHI study.

Our objective was to establish consensus on (1) which patients with plaque psoriasis and limited skin involvement (body surface area [BSA] <10%) are suitable for systemic treatment, and (2) a definition of 'topical therapy failure'. A steering committee refined 13 statements drawn from literature related to the study objectives. An independent panel of 45 clinical experts from Japan indicated their agreement to each statement using a 10-point Likert scale (Round 1; strong consensus, ≥70% of responses = 7-10 and median value ≥8). The steering committee reviewed Round 1 results and refined the statements for Round 2, as necessary. In Round 2, the panel indicated their agreement to each statement using a 3-point scale (strong consensus, ≥70% of responses and median value of 3) and were shown Round 1 responses before voting. Forty-five clinicians participated in Round 1 and 41 of those (91%) participated in Round 2. Consensus was achieved on the criteria of eligibility for systemic treatment among patients with limited skin involvement as disease involvement at special or difficult to treat areas, psoriasis-induced psychological distress, uncontrolled symptoms (e.g., scaling, bleeding, pruritus, insomnia) affecting their social life, psoriatic arthritis, or failure of topical therapy. Consensus on criteria for topical failure were persistent symptoms (e.g., itchiness, pain) and plaques, poor patient satisfaction with treatment, a need to increase medication quantity or application time after treatment with two topicals for 4 weeks; or if the Psoriasis Area Severity Index score of >3 or Physician Global Assessment Score of ≥2 after 8 weeks treatment. Our Delphi panel proposes criteria to help physicians identify patients with psoriasis and limited skin involvement who would benefit from systemic therapy and suggests a definition for topical therapy 'failure' which could indicate a move to systemic treatment is warranted.

Comparison of Three Physician Global Assessment Instruments in Systemic Sclerosis.

Physician global assessments (PhyGAs) are variably applied in systemic sclerosis (SSc) clinical trials. The comparability of different PhyGA results is unknown. We sought to assess the comparability of results from three different PhyGA instruments simultaneously applied in the Australian Scleroderma Cohort Study (ASCS). Using data from 1,965 ASCS participants, we assessed the correlation between results of three PhyGA assessments: (1) overall health, (2) activity, and (3) damage. We evaluated the concordance of change in each PhyGA between study visits. Ordered logistic regression analysis was used to evaluate the clinical associations of each PhyGA. The absolute scores of each PhyGA were strongly correlated at individual study visits. Concordant changes of the PhyGA scores occurred between 50% of study visits. Only patient-reported breathlessness was associated with all three PhyGA scores (overall health: odds ratio [OR] 1.67, P < 0.01; activity: OR 1.44, P < 0.01; damage: OR 1.32, P < 0.01). Changes in physician-assessed activity scores were also associated with patient-reported worsening skin disease (OR 1.25, P = 0.03) and fecal incontinence (OR 1.23, P = 0.01), whereas damage scores were associated with respiratory disease (pulmonary arterial hypertension: OR 1.25, P = 0.03; chronic obstructive pulmonary disease: OR 1.37, P = 0.04), as well as skin scores (OR 1.02, P < 0.01) and fecal incontinence (OR 1.21, P = 0.02). PhyGAs of overall health, activity, and damage are each associated with different SSc features, and changes in different PhyGA scores are discordant 50% of the time. Our findings suggest results of variably worded PhyGAs are not directly interchangeable and support the development of a standardized PhyGA.

Pregnancy outcomes among women with inflammatory bowel disease: A UK tertiary centre experience.

Optimal management of inflammatory bowel disease (IBD) in pregnancy is associated with better pregnancy outcomes. We describe management of IBD during pregnancy and maternal and fetal outcomes of patients from a tertiary UK IBD centre. This is a retrospective observational cohort study of all pregnancies occurring between 2015 and 2021 in a large tertiary IBD centre in the UK. IBD activity and management prior to, during and after pregnancy were recorded along with pregnancy and neonatal outcomes. Associations between IBD-focused interventions and any adverse pregnancy outcomes, as well as the association between IBD severity and treatments and adverse maternofetal outcomes were assessed. Pregnancies in 130 women with IBD were included for analysis. The mean maternal age at delivery was 30.5 (± 4.7) years. At conception, 73 women (56.2%) were in clinical remission and 24 (18.4%) were treated with a biologic agent. Active disease during pregnancy, measured by physician global assessment, was less frequent in women who were in clinical remission at conception, compared to those not in remission at conception (16/73 21.9% vs. 39/49 79.6%; data insufficient for eight women). Active IBD at conception was associated with pre-term birth (p = 0.04). Maternal corticosteroid use in any trimester was associated with low birth weight (T1 p = 0.02; T2 p = 0.005; T3 p = 0.007). Active disease (p = 0.008) and steroid use in the third trimester (p = 0.05) were both associated with neonatal infections up to sixmonths after birth. Women in clinical remission at the time of conception have favorable outcomes, consistent with prospective observational studies. Our observations emphasize the importance of high quality IBD care for women pre and post-partum in line with international recommendations.

Model-Informed Assessment of Probability of Phase 3 Success for Ritlecitinib in Patients with Moderate-to-Severe Ulcerative Colitis.

Ritlecitinib, an oral Janus kinase 3/tyrosine kinase expressed in hepatocellular carcinoma family inhibitor, was evaluated in patients with ulcerative colitis (UC) in a phase 2b trial. Model-informed drug development strategies were applied to bridge observations from phase 2b to predictions for a proposed phase 3 study design to assess the probability of achieving the target efficacy outcome. A longitudinal exposure-response model of the time course of the 4 Mayo subscores (rectal bleeding, stool frequency, physician's global assessment, and endoscopic subscore) in patients with UC receiving placebo or ritlecitinib was developed using population modeling approaches and an item response theory framework. The quantitative relationships between the 4 Mayo subscores accommodated the prediction of composite endpoints such as total Mayo score and partial Mayo score (key endpoints from phase 2b), and modified clinical remission and endoscopic remission (proposed phase 3 endpoints). Clinical trial simulations using the final model assessed the probability of candidate ritlecitinib dosing regimens (including those tested in phase 2b and alternative) and phase 3 study designs for achieving target efficacy outcomes benchmarked against an approved treatment for moderate-to-severe UC. The probabilities of achieving target modified clinical remission and endoscopic improvement outcomes at both weeks 8 and 52 for ritlecitinib 100 mg once daily was 74.8%. Model-based assessment mitigated some of the risk associated with proceeding to pivotal phase 3 trials with dosing regimens of which there was limited clinical experience.
