Abstract
PURPOSE To report the use of tofacitinib in ten patients with scleritis where the traditional immunomodulation was not successful or could not be used. METHOD A retrospective chart review. RESULT Tofacitinib was successful in the treatment of scleritis in patients either recalcitrant to or intolerant to conventional therapy in 9 out of 10 cases reported here. Two patients had developed reactivation of herpetic infection after 1 month of starting tofacitinib. The duration from diagnosis of scleritis to the institution of tofacitinib therapy varied from 1 month to 60 months. Duration of follow-up varies from 2 months to 11 months. CONCLUSION Tofacitinib can be used as an important future option for managing recurrent and recalcitrant cases of scleritis.

Abstract
Juvenile Idiopathic Arthritis (JIA) is the most common chronic rheumatic disease in childhood, and is associated with uveitis in up to 20-25% of cases. Typically, the uveitis is chronic, asymptomatic, non-granulomatous and anterior. For this reason, screening for uveitis is recommended to identify uveitis early and allow treatment to prevent sight-threatening complications. The management of JIA associated uveitis requires a multidisciplinary approach and a close collaboration between paediatric rheumatologist and ophthalmologist. Starting the appropriate treatment to control uveitis activity and prevent ocular complications is crucial. Current international recommendations advise a step-wise approach, starting with methotrexate and moving on to adalimumab if methotrexate alone is not sufficient to control the disease. If the uveitis remains active despite standard treatment other therapeutic options may be considered including anti-IL6 or other anti-TNF agents such as infliximab, although the evidence for these agents is limited.

Safety and efficacy of tofacitinib for the treatment of patients with juvenile idiopathic arthritis: preliminary results of an open-label, long-term extension study. Ann Rheum Dis 2024:ard-2023-225094. [PMID: 38849152 DOI: 10.1136/ard-2023-225094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 05/22/2024] [Indexed: 06/09/2024]
Abstract
OBJECTIVES We report the safety, tolerability and efficacy of tofacitinib in patients with juvenile idiopathic arthritis (JIA) in an ongoing long-term extension (LTE) study. METHODS Patients (2-<18 years) with JIA who completed phase 1/3 index studies or discontinued for reasons excluding treatment-related serious adverse events (AEs) entered the LTE study and received tofacitinib 5 mg two times per day or equivalent weight-based doses. Safety outcomes included AEs, serious AEs and AEs of special interest. Efficacy outcomes included improvement since tofacitinib initiation per the JIA-American College of Rheumatology (ACR)70/90 criteria, JIA flare rate and disease activity measured by Juvenile Arthritis Disease Activity Score (JADAS)27, with inactive disease corresponding to JADAS ≤1.0. RESULTS Of 225 patients with JIA (median (range) duration of treatment, 41.6 (1-103) months), 201 (89.3%) had AEs; 34 (15.1%) had serious AEs. 10 patients developed serious infections; three had herpes zoster. Two patients newly developed uveitis. Among patients with polyarticular course JIA, JIA-ACR70/90 response rates were 60.0% (78 of 130) and 33.6% (47 of 140), respectively, at month 1, and generally improved over time. JIA flare events generally occurred in <5% of patients through to month 48. Observed mean (SE) JADAS27 was 22.0 (0.6) at baseline, 6.2 (0.7) at month 1 and 2.8 (0.5) at month 48, with inactive disease in 28.8% (36 of 125) of patients at month 1 and 46.8% (29 of 82) at month 48. CONCLUSIONS In this interim analysis of LTE study data in patients with JIA, safety findings were consistent with the known profile of tofacitinib, and efficacy was maintained up to month 48. TRIAL REGISTRATION NUMBER NCT01500551.

Comparison of efficacy and safety of tofacitinib and azathioprine in patients with alopecia areata and variants: a double-blind, randomized controlled trial. Arch Dermatol Res 2024; 316:458. [PMID: 38967866 DOI: 10.1007/s00403-024-03203-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 06/21/2024] [Accepted: 06/23/2024] [Indexed: 07/06/2024]
Abstract
BACKGROUND Alopecia areata (AA) is an autoimmune pathology manifested by loss of hair. OBJECTIVE To evaluate and compare the efficacy and safety of tofacitinib and azathioprine in patients with AA and variants. METHODS In this double-blind randomized controlled trail (RCT) carried out at the Department of Dermatology, Medical Teaching Institute-Lady Reading Hospital (MTI-LRH), Peshawar, Pakistan, patients aged ≥ 12 years diagnosed with AA, alopecia totalis (AT) or alopecia universalis (AU) with minimum 50% scalp hair loss for a period ≥ 06 years were included. Patients were randomly assigned to receive oral tofacitinib 5 mg twice daily (Group I) or oral azathioprine 2 mg/kg body weight once daily (Group II). The primary endpoint was Severity of Alopecia Tool (SALT) score, evaluated at baseline and 06 months follow-up. Safety was consistently assessed during the study. RESULTS A total of 104 patients underwent random allocation into either the tofacitinib group (n = 52) or the azathioprine group (n = 52). The mean (SD) age of patients was 20.23 (7.14) years and 22.26 (8.07) years, while the mean (SD) disease duration was 6.59 (4.01) years and 7.98 (4.40) years in in Group I and II, respectively. Overall, 40 (38.5%) patients were adolescents while 70 (67.3%) were male. 52 (50%) had AA, 37 (35.5%) had AT and 15 (14.5%) had AU. Mean baseline SALT score in tofacitinib group was 91.02 ± 10.21 and azathioprine group was 91.02 ± 10.63, which at 06 months follow-up improved to 14.1 ± 24.6 and 63.9 ± 33.9, respectively (difference, 11.5 points; 95% confidence interval, 38.3-61.3, p < 0.0001). Overall, no major adverse effects and no difference among the minor adverse effects in the two groups (04 adverse events for tofacitinib group and 08 for azathioprine group: p = 0.23) was observed. CONCLUSIONS Efficacy of tofacitinib was significantly higher than azathioprine, whilst both drugs were well-tolerated in patients with AA and variants.

JAK inhibitors in refractory juvenile rheumatic diseases: Efficacy, tolerance and type-I interferon profiling, a single center retrospective study. J Autoimmun 2024; 147:103248. [PMID: 38797048 DOI: 10.1016/j.jaut.2024.103248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 04/16/2024] [Accepted: 05/06/2024] [Indexed: 05/29/2024]
Abstract
OBJECTIVES - Janus Kinase inhibitors (JAKi) are a new class of drugs available for pediatric rheumatic diseases. This study aimed to describe the safety and effectiveness of JAKi in these diseases, with a focus on longitudinal interferon-stimulated genes (ISG) assessment. METHODS - We present a single-center retrospective study of children with refractory pediatric rheumatic diseases including connective tissue diseases, monogenic type I interferonopathies or juvenile idiopathic arthritis, receiving JAKi. According to physicians' assessment, treatment effectiveness was classified at 12 months as a complete response in the total absence of disease activity, partial response in case of significant (>50%) but incomplete improvement or no response in the case of non-response or improvement of less than 50% of the clinical and biological parameters. ISG were monitored longitudinally using Nanostring technology. RESULTS - 22 children were retrospectively included in this study, treated either by baricitinib or ruxolitinib. Complete response was achieved at 12 months in 9/22 (41%) patients. 6/22 (27%) patients were non-responders and treatment had been discontinued in five of them. Within the interferon (IFN)-related diseases group, ISG-score was significantly reduced 12 months after JAKi onset (p = 0.0068). At 12 months, daily glucocorticoid doses had been reduced with a median dose of 0.16 mg/kg/day (IQR 0.11; 0.33) (p = 0.0425). 7/22 (32%) patients had experienced side effects, infections being the most common. Increase of the body mass index was also recorded in children in the first 6 months of treatment. CONCLUSION - JAKi represent a promising treatment of immune-mediated pediatric diseases, enabling to decrease type-I IFN transcriptomic signature in responding patients, especially in the context of juvenile dermatomyositis. JAKi represent steroid-sparing drugs but they induce metabolic changes linked to weight gain, posing a concern in the treatment of young patients and teenagers. More data are required to define the efficacy and safety of JAKi in the management of refractory pediatric rheumatic diseases.

Abstract
PURPOSE OF REVIEW This review summarizes latest developments in treatment of juvenile spondyloarthritis (JSpA), specifically enthesitis-related arthritis (ERA) and juvenile psoriatic arthritis (JPsA). RECENT FINDINGS There has been addition of biologic disease modifying antirheumatic drugs (bDMARDs) beyond tumor necrosis factor inhibitors (TNFi) for JSpA such as IL-17 blockers, IL-23 blockers, and janus activating kinase inhibitors with favorable safety profile. Conducting robust clinical trials for this subpopulation of JIA remains a challenge; extrapolation studies are being used to obtain approval from regulatory agencies. SUMMARY Newer drug therapies have expanded the scope of treatment for patients with JSpA. bDMARDs such as adalimumab, etanercept, infliximab, and secukinumab have demonstrated clinically significant treatment efficacy in ERA and JPsA. Based on extrapolation studies, intravenous golimumab, etanercept, abatacept, and ustekinumab have gained Food and Drug Administration (FDA) approval for JPsA. Long-term follow-up studies continue to demonstrate acceptable safety profiles. There is need for more real-world data on drug efficacy from Registry studies and research on effective de-escalation strategies.

Abstract
Individuals with Down syndrome (DS), the genetic condition caused by trisomy 21 (T21), display clear signs of immune dysregulation, including high rates of autoimmune disorders and severe complications from infections. Although it is well established that T21 causes increased interferon responses and JAK/STAT signaling, elevated autoantibodies, global immune remodeling, and hypercytokinemia, the interplay between these processes, the clinical manifestations of DS, and potential therapeutic interventions remain ill defined. Here, we report a comprehensive analysis of immune dysregulation at the clinical, cellular, and molecular level in hundreds of individuals with DS. We demonstrate multi-organ autoimmunity of pediatric onset concurrent with unexpected autoantibody-phenotype associations. Importantly, constitutive immune remodeling and hypercytokinemia occur from an early age prior to autoimmune diagnoses or autoantibody production. We then report the interim analysis of a Phase II clinical trial investigating the safety and efficacy of the JAK inhibitor tofacitinib through multiple clinical and molecular endpoints. Analysis of the first 10 participants to complete the 16-week study shows a good safety profile and no serious adverse events. Treatment reduced skin pathology in alopecia areata, psoriasis, and atopic dermatitis, while decreasing interferon scores, cytokine scores, and levels of pathogenic autoantibodies without overt immune suppression. Additional research is needed to define the effects of JAK inhibition on the broader developmental and clinical hallmarks of DS. ClinicalTrials.gov identifier: NCT04246372.

Abstract
INTRODUCTION Juvenile dermatomyositis (JDM) is a rare autoimmune disease most commonly with proximal weakness due to inflammation and characteristic skin rashes. Most patients have a chronic or polycyclic disease course on standard therapy so better treatments are needed. An interferon signature is well-established in key tissues of JDM. Janus kinase inhibitors (jakinibs), which can decrease IFN signaling, are therefore appealing as a targeted therapy. AREAS COVERED Herein is a review of the growing literature on JDM patients in jakinibs, including specifics of their jakinib exposure, summary of efficacy, disease features, and characteristics of patients treated, and safety parameters. EXPERT OPINION The vast majority of refractory JDM patients respond to jakinib therapy, though they have varied features, doses, and previous/concurrent medications, and data is largely retrospective. Jakinibs are an exciting and promising treatment in JDM. Evaluation with larger prospective controlled studies is needed to answer remaining questions about jakinibs in JDM regarding dosing, which JDM patients to treat with jakinibs, potential biomarkers to use, and how best to monitor safety risks in JDM.

Abstract
(1) Background: Achieving inactive disease decreases long-term joint damage in patients with polyarticular juvenile idiopathic arthritis (polyJIA). The aim of our study was to describe average time to treatment and medication changes over time. (2) Methods: Incident polyJIA patients were retrospectively identified in the InGef and WIG2 longitudinal health claims databases. Drug escalation level changes were evaluated longitudinally and cross-sectionally across three years, as follows: no treatment, glucocorticoids (GCs) and/or non-steroidal anti-inflammatory drugs (NSAIDs), conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and biological disease-modifying antirheumatic drugs (bDMARDs). (3) Results: On average, newly diagnosed polyJIA patients received their first csDMARD prescription after 128 days and their first bDMARD prescription after 327 days. More patients were treated with csDMARDs than with bDMARDs at diagnosis; however, 24% and 12% (InGef and WIG2 databases, respectively) had no JIA treatment. After three years, 45% and 31% were not taking any treatments, while 18% and 36% were prescribed bDMARDs. Among patients initiating bDMARDs, most continued treatment for three years, with some switching to csDMARDs or discontinuing treatment. Patients treated only with csDMARDs took them longer, compared to those additionally taking other DMARDs. Patients treated with bDMARDs took them about twice as long as the csDMARDs they took prior. (4) Conclusion: A substantial number of patients with polyJIA are not treated as intensively as guidelines recommend.

Comparative efficacy and safety of different drugs in patients with systemic juvenile idiopathic arthritis: A systematic review and network meta-analysis. Medicine (Baltimore) 2024; 103:e38002. [PMID: 38701278 PMCID: PMC11062668 DOI: 10.1097/md.0000000000038002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 04/04/2024] [Indexed: 05/05/2024] Open
Abstract
BACKGROUND The goal of this study was to estimate the relative efficacy and safety of different biological agents (infliximab, canakinumab, baricitinib, anakinra, adalimumab, tofacitinib, tocilizumab, and rilonacept) compared with placebo for systemic juvenile idiopathic arthritis (JIA) patients, through a network meta-analysis. METHODS Pubmed, Embase, and Cochrane Library were searched from database inception to July 2023 for randomized controlled trials comparing different biological agents (infliximab, canakinumab, baricitinib, anakinra, adalimumab, tofacitinib, tocilizumab, and rilonacept) or placebo directly or indirectly in JIA. Bayesian network meta-analyses were conducted. Data was extracted and analyzed by R with gemtc package. The treatment options were ranked using the surface under the cumulative ranking curve (SUCRA) value. RESULTS We identified 10 randomized controlled trials and analyzed 898 participants. Canakinumab (odds ratio 55.0, 95% credible intervals 2.4-67.0) was more effective than the placebo, and the difference was statistically significant. However, there was no statistical significance between other drugs versus placebo in terms of the modified ACRpedi30 (P > .05). The SUCRA shows that canakinumab ranked first (SUCRA, 86.9%), anakinra ranked second (SUCRA, 77.7%), adalimumab ranked third (SUCRA, 61.9%), and placebo ranked the last (SUCRA, 6.3%). Nevertheless, there were no notable discrepancies in the occurrence of adverse events, hepatic-related adverse events, infectious adverse event, serious adverse events, and serious infection following treatment with canakinumab, anakinra, tocilizumab, rilonacept, or the placebo. Based on the clustergram of modified ACRpedi30 and adverse events, canakinumab is suggested for JIA according to the surface under SUCRAs considering the symptom and adverse events simultaneously. CONCLUSIONS Among patients with JIA, canakinumab exhibited the highest likelihood of being the optimal treatment for achieving the modified ACRpedi30 response rate, and neither of the tested biological agents carried a significant risk of serious adverse events.

Validation of new medication use algorithms as proxies for worsening disease activity in patients with juvenile idiopathic arthritis. Pharmacoepidemiol Drug Saf 2024; 33:e5803.

Abstract
PURPOSE To facilitate claims-based research on populations with juvenile idiopathic arthritis (JIA), we sought to validate an algorithm of new medication use as a proxy for worsening JIA disease activity. METHODS Using electronic health record data from three pediatric centers, we defined new JIA medication use as (re)initiation of disease-modifying antirheumatic drugs or glucocorticoids (oral or intra-articular). Data were collected from 201 randomly selected subjects with (101) or without (100) new medication use. We assessed the positive predictive value (PPV) and negative predictive value (NPV) based on a reference standard of documented worsening of JIA disease activity. The algorithm was refined to optimize test characteristics. RESULTS Overall, the medication-based algorithm had suboptimal performance in representing worsening JIA disease activity (PPV 69.3%, NPV 77.1%). However, algorithm performance improved for definitions specifying longer times after JIA diagnosis (≥1-year post-diagnosis: PPV 82.9%, NPV 80.0%) or after initiation of prior JIA treatment (≥1-year post-treatment: PPV 89.7%, NPV 80.0%). CONCLUSION An algorithm for new JIA medication use appears to be a reasonable proxy for worsening JIA disease activity, particularly when specifying new use ≥1 year since initiating a prior JIA medication. This algorithm will be valuable for conducting research on JIA populations within administrative claims databases.

Abstract
Juvenile psoriatic arthritis (JPsA) is a heterogeneous type of non-systemic chronic inflammatory arthritis affecting children and young people. This review focuses on highlighting challenges in harmonising recommendations for the use of available therapies in JPsA, according to its distinct clinical phenotypes, and explores the similarities and differences between the disease classification and management across age. We further explore the emerging therapeutic landscape, summarising the recently completed clinical trials in JPsA, and ongoing studies in both JPsA and adults with psoriatic arthritis, highlighting unmet needs and barriers for translational research in JPsA. The novel therapeutic agents in clinical development in JPsA range from monoclonal antibodies targeting interleukin (IL)-17, IL-12/23 and IL-23 blockades to synthetic small molecules targeting Janus kinase and tyrosine kinase and phosphodiesterase-4 inhibition. In addition, there are head-to-head clinical trials comparing tumour necrosis factor-α blockade with both IL-17 and IL-23 inhibition. Most of these new therapies have been tested in adults with psoriatic arthritis and have advanced to the phase III stage of drug development or received license for use, suggesting promising signals for efficacy and potentially acceptable safety and tolerability for JPsA. Further translational research in JPsA is required to improve our understanding of the impact of age at onset on treatment efficacy, as well as to provide opportunities for better management of refractory disease and improved long-term outcomes in JPsA, for ultimate patient benefit.

Abstract
OBJECTIVE Our objective was to develop and validate cutoff values in the systemic Juvenile Arthritis Disease Activity Score 10 (sJADAS10) that distinguish the states of inactive disease (ID), minimal disease activity (MDA), moderate disease activity (MoDA), and high disease activity (HDA) in children with systemic juvenile idiopathic arthritis, based on subjective disease state assessment by the treating pediatric rheumatologist. METHODS The cutoff definition cohort was composed of 400 patients enrolled at 30 pediatric rheumatology centers in 11 countries. Using the subjective physician rating as an external criterion, six methods were applied to identify the cutoffs: mapping, calculation of percentiles of cumulative score distribution, the Youden index, 90% specificity, maximum agreement, and receiver operating characteristic curve analysis. Sixty percent of the patients were assigned to the definition cohort, and 40% were assigned to the validation cohort. Cutoff validation was conducted by assessing discriminative ability. RESULTS The sJADAS10 cutoffs that separated ID from MDA, MDA from MoDA, and MoDA from HDA were ≤2.9, ≤10, and >20.6, respectively. The cutoffs discriminated strongly among different levels of pain, between patients with and without morning stiffness, and among patients whose parents judged their disease status as remission or persistent activity or flare or were satisfied or not satisfied with current illness outcome. CONCLUSION The sJADAS cutoffs revealed good metrologic properties in both definition and validation cohorts and are therefore suitable for use in clinical trials and routine practice.

Abstract
PURPOSE Autoimmune bullous diseases, connective tissue diseases, and vasculitis represent a group of severe rare skin diseases. While glucocorticoids and immunosuppressive agents serve as standard treatments for these diseases, their efficacy is limited due to adverse side effects, indicating the need for alternative approaches. Biologics have been used in the management of some rare skin diseases. However, the use of biologics is associated with concerns, such as infection risk and high costs, prompting the quest for efficacious and cost-effective alternatives. This study discusses the safety issues associated with tofacitinib and its potential in treating rare skin diseases. METHODS This narrative review focuses on the pharmacodynamic properties of tofacitinib and its impact on the JAK/STAT pathway. In addition, we present a comprehensive discussion of the effects and mechanism of action of tofacitinib for each severe rare skin disease. RESULTS This role of tofacitinib in treating severe rare skin diseases has been discussed, shedding light on its promising prospects as a treatment modality. Few reports of serious adverse events are available in patients treated with tofacitinib. CONCLUSION We explored the mechanism of action, efficacy, and safety considerations of tofacitinib and found that it can be used as a treatment option for rare skin diseases. However, multicenter clinical studies are needed to confirm the efficacy and safety of JAK inhibitors.

Abstract
These analyses characterized tofacitinib pharmacokinetics (PKs) in children and adolescents with juvenile idiopathic arthritis (JIA). Data were pooled from phase I (NCT01513902), phase III (NCT02592434), and open-label, long-term extension (NCT01500551) studies of tofacitinib tablet/solution (weight-based doses administered twice daily [b.i.d.]) in patients with JIA aged 2 to less than 18 years. Population PK modeling used a nonlinear mixed-effects approach, with covariates identified using stepwise forward-inclusion backward-deletion procedures. Simulations were performed to derive dosing recommendations for children and adolescents with JIA. Two hundred forty-six pediatric patients were included in the population PK model. A one-compartment model with first-order elimination and absorption with body weight as a covariate for oral clearance and apparent volume of distribution sufficiently described the data. Oral solution was associated with comparable average concentration (Cavg) and slightly higher (113.9%) maximum concentration (Cmax) versus tablet, which was confirmed by a subsequent randomized, open-label, bioavailability study conducted in healthy adult participants (n = 12) by demonstrating adjusted geometric mean ratios (90% confidence interval) between oral solution and tablet of 1.04 (1.00-1.09) and 1.10 (1.00-1.21) for area under the curve extrapolated to infinity and Cmax, respectively (NCT04111614). A dosing regimen of 3.2 mg b.i.d. solution in patients 10 to less than 20 kg, 4 mg b.i.d. solution in patients 20 to less than 40 kg, and 5 mg b.i.d. tablet/solution in patients greater than or equal to 40 kg, irrespective of age, was proposed to achieve constant Cavg across weight groups. In summary, population PK characterization informed a simplified tofacitinib dosing regimen that has been implemented in pediatric patients with JIA.

Abstract
Juvenile idiopathic arthritis (JIA) is a chronic clinical condition characterized by arthritic features in children under the age of 16, with at least 6 weeks of active symptoms. The etiology of JIA remains unknown, and it is associated with prolonged synovial inflammation and structural joint damage influenced by environmental and genetic factors. This review aims to enhance the understanding of JIA by comprehensively analyzing relevant literature. The focus lies on current diagnostic and therapeutic approaches and investigations into the pathoaetiologies using diverse research modalities, including in vivo animal models and large-scale genome-wide studies. We aim to elucidate the multifactorial nature of JIA with a strong focus towards genetic predilection, while proposing potential strategies to improve therapeutic outcomes and enhance diagnostic risk stratification in light of recent advancements. This review underscores the need for further research due to the idiopathic nature of JIA, its heterogeneous phenotype, and the challenges associated with biomarkers and diagnostic criteria. Ultimately, this contribution seeks to advance the knowledge and promote effective management strategies in JIA.

Biologic and targeted synthetic DMARDs (b/tsDMARDs) have revolutionized the management of multiple rheumatic inflammatory conditions. Among these, polyarticular JIA (pJIA) and RA display similarities in terms of disease pathophysiology and response pattern to b/tsDMARDs. Indeed, the therapeutic efficacy of novel targeted drugs is variable among individual patients, in both RA and pJIA. The mechanisms and determinants of this heterogeneous response are diverse and complex, such that the development of true 'precision'-medicine strategies has proven highly challenging. In this review, we will discuss pathophysiological, patient-specific, drug-specific and environmental factors contributing to individual therapeutic response in pJIA in comparison with what is known in RA. Although some biomarkers have been identified that stratify with respect to the likelihood of either therapeutic response or non-response, few have proved useful in clinical practice so far, likely due to the complexity of treatment-response mechanisms. Consequently, we propose a pragmatic, patient-centred and clinically based approach, i.e. personalized instead of biomarker-based precision medicine in JIA.

Abstract
Psoriatic arthritis (PsA) is a complex inflammatory disease characterized by musculoskeletal and non-musculoskeletal manifestations. It is a distinct disease entity at the interface between rheumatology and dermatology, making it challenging to manage. The diverse clinical presentation and severity of PsA require a multidisciplinary approach for optimal care. Early diagnosis and management are necessary to improving quality of life for patients. In Saudi Arabia, there is currently no unified national consensus on the best practices for managing PsA. This lack of consensus leads to debate and uncertainty in the treatment of the disease, resulting in over or under prescribing of biological agents. To address this issue, a multidisciplinary work group was formed by the Saudi Ministry of Health. This group, consisting of dermatologists, rheumatologists, and pharmacists, aimed to develop evidence-based consensus recommendations for he use and monitoring of biological therapy in PsA management. The work group conducted five consensus workshops between December 2021 to March 2022. Using the nominal group technique, they discussed various aspects of PsA management, including eligibility criteria for biological treatment, monitoring of disease activity, treatment goals, screening, precautions, and management of PsA with biologic therapies. The group also considered special considerations for patients with comorbidities, pregnant and lactating women, as well as pediatric and adolescent populations. The resulting consensus document provides recommendations that are applicable to the Saudi setting, taking into account international guidelines and the specific needs of PsA patients in the country. The consensus document will be regularly updated to incorporate new data and therapeutic agents as they become available. Key Points • In Saudi Arabia, there is a lack of unified national consensus on the optimal management of PsA, therefore, this article aims to provide up-to-date evidence-based consensus recommendations for the optimal use and monitoring of biologic therapy in the management of PsA in Saudi Arabia. • The consensus development process was undertaken by a multidisciplinary work group of 13 experts, including two dermatologists, six rheumatologists, and five pharmacists. • There is more than one disease activity tool used in PsA disease, depending on the disease domain - peripheral arthritis Disease Activity Index in Psoriatic Arthritis (DAPSA) or Minimal Disease Activity (MDA), axial PsA Ankylosing Spondylitis Disease Activity Score (ASDAS), and dactylitis and enthesitis MDA. • The main goal of therapy in all patients with PsA is to achieve the target of remission, or alternatively, low disease activity in all disease domains and improve quality of life (QoL).

Abstract
In the past two decades, the treatment of juvenile idiopathic arthritis (JIA) has evolved markedly, owing to the availability of a growing number of novel, potent and relatively safe therapeutic agents and the shift of management strategies towards early achievement of disease remission. However, JIA encompasses a heterogeneous group of diseases that require distinct treatment approaches. Furthermore, some old drugs, such as methotrexate, sulfasalazine and intraarticular glucocorticoids, still maintain an important therapeutic role. In the past 5 years, information on the efficacy and safety of drug therapies for JIA has been further enriched through the accomplishment of several randomized controlled trials of newer biologic and synthetic targeted DMARDs. In addition, a more rational therapeutic approach has been fostered by the promulgation of therapeutic recommendations and guidelines. A multinational collaborative effort has led to the development of the recommendations for the treat-to-target strategy in JIA. There is currently increasing interest in establishing the optimal time and modality for discontinuation of treatment in children with JIA who achieve sustained clinical remission. The aim of this Review is to summarize the current evidence and discuss the therapeutic approaches to the management of non-systemic phenotypes of JIA, including oligoarthritis, polyarthritis, enthesitis-related arthritis and psoriatic arthritis.

Abstract
INTRODUCTION The management of refractory juvenile idiopathic associated uveitis (JIAU) or childhood-onset chronic anterior uveitis (CAU) is a challenge. There is no clear consensus or evidence base for to suggest the most appropriate therapy after primary or secondary failure of biweekly adalimumab. In this scenario, most clinicians advocate switching to another anti-tumor necrosis factor alpha inhibitor; however, there are a variety of other disease modifying agents to choose from albeit with a differing levels of evidence. AREAS COVERED We discuss how to define nonresponse and potential treatment options for patients with JIAU and CAU refractory to biweekly adalimumab. EXPERT OPINION Uncontrolled CAU and JIAU remain one of the most challenging diseases to manage and can lead to irreversible loss of vision in a third of those affected. Amongst the possible choices, weekly adalimumab, infliximab, tocilizumab and abatacept have more evidence to support their use. JAK inhibitors seem to be a promising option. Golimumab and Rituximab has also been thought to be partially effective in some refractory cases, whereas IL-17, IL-23, and IL-12 inhibition along with apremilast seem not to be a therapeutic option currently. The route of administration should also be considered as there can be significant pros and cons for different children.

EBioMedicine 2024; 100:104946.

Abstract
BACKGROUND Methotrexate (MTX) is the gold-standard first-line disease-modifying anti-rheumatic drug for juvenile idiopathic arthritis (JIA), despite only being either effective or tolerated in half of children and young people (CYP). To facilitate stratified treatment of early JIA, novel methods in machine learning were used to i) identify clusters with distinct disease patterns following MTX initiation; ii) predict cluster membership; and iii) compare clusters to existing treatment response measures. METHODS Discovery and verification cohorts included CYP who first initiated MTX before January 2018 in one of four UK multicentre prospective cohorts of JIA within the CLUSTER consortium. JADAS components (active joint count, physician (PGA) and parental (PGE) global assessments, ESR) were recorded at MTX start and over the following year. Clusters of MTX 'response' were uncovered using multivariate group-based trajectory modelling separately in discovery and verification cohorts. Clusters were compared descriptively to ACR Pedi 30/90 scores, and multivariate logistic regression models predicted cluster-group assignment. FINDINGS The discovery cohorts included 657 CYP and verification cohorts 1241 CYP. Six clusters were identified: Fast improvers (11%), Slow Improvers (16%), Improve-Relapse (7%), Persistent Disease (44%), Persistent PGA (8%) and Persistent PGE (13%), the latter two characterised by improvement in all features except one. Factors associated with clusters included ethnicity, ILAR category, age, PGE, and ESR scores at MTX start, with predictive model area under the curve values of 0.65-0.71. Singular ACR Pedi 30/90 scores at 6 and 12 months could not capture speeds of improvement, relapsing courses or diverging disease patterns. INTERPRETATION Six distinct patterns following initiation of MTX have been identified using methods in artificial intelligence. These clusters demonstrate the limitations in traditional yes/no treatment response assessment (e.g., ACRPedi30) and can form the basis of a stratified medicine programme in early JIA.

Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) is a prevalent childhood chronic arthritis, often persisting into adulthood. Effective transitional care becomes crucial as these patients transition from pediatric to adult healthcare systems. Despite the concept of transitional care being recognized, its real-world implementation remains inadequately explored. This study aims to evaluate the thoughts and practices of healthcare providers regarding transitional care for JIA patients. METHODS A cross-sectional survey was conducted among pediatric and adult rheumatologists in Turkey. Based on the American Academy of Pediatrics' six core elements of transitional care, the survey included 86 questions. The respondents' demographic data, attitudes towards transitional care, and practical implementation were assessed. RESULTS The survey included 48 rheumatologists, with 43.7% having a transition clinic. The main barriers to establishing transition programs were the absence of adult rheumatologists, lack of time, and financial constraints. Only 23.8% had a multidisciplinary team for transition care. Participants agreed on the importance of coordination and cooperation between pediatric and adult healthcare services. The timing of the transition process varied, with no consensus on when to initiate or complete it. Participants advocated for validated questionnaires adapted to local conditions to assess transition readiness. CONCLUSIONS The study sheds light on the challenges and perspectives surrounding transitional care for JIA patients in Turkey. Despite recognized needs and intentions, practical implementation remains limited due to various barriers. Cultural factors and resource constraints affect the transition process. While acknowledging the existing shortcomings, the research serves as a ground for further efforts to improve transitional care and ensure better outcomes for JIA patients transitioning into adulthood.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. The International League of Associations for Rheumatology (ILAR) has defined JIA as "arthritis of unknown etiology persisting for ≥6 wk with an onset at <16 y of age, after excluding other causes of joint inflammation". Synovial inflammation is the result of a complex interplay of aberrant immune systems (both adaptive and innate) in a genetically susceptible individual, with possible external stimuli/triggers. Diagnosis of JIA essentially remains clinical, and laboratory investigations usually help to assess the severity of disease activity. Few investigations like antinuclear antibodies (ANA), human leukocyte antigen (HLA)-B27, and rheumatoid factor (RF) help to categorize or prognosticate a child with JIA. Timely use of effective therapeutic interventions including biological has shown good long-term outcomes of JIA.

Abstract
OBJECTIVES To characterise redactions in clinical trials and estimate a time when all protocols are fully removed (RAPTURE). DESIGN Redacted cross sectional study. SETTING Published phase 3 randomised controlled trials from 1 January 2010 to ██████████████. PARTICIPANTS New England Journal of Medicine, ██████████, and Journal of the American Medical Association. MAIN OUTCOME MEASURES █████ ████████ ██████████████ ██████ ██████████ ████████ ████████ ██████████ ███████████ ████████████ ████████████ ████████████████████████ ██████████████████ RESULTS: ████████████████████ met the inclusion criteria, with 268 (56.7%) research protocols available and accessible. The rate of redactions in protocols has increased from 0 in 2010 to 60.8% in 2021 (P<0.001). The degree of data redaction has also increased, with the average cumulative redactions among industry funded trials rising from 0 in 2010 to 3.5 pages in 2021 (P<0.001). Modelling predicts that RAPTURE is expected to occur between 2073 and 2136. Redactions featured predominantly in ████████ sponsored trials and mostly occurred in the statistical design. CONCLUSIONS This study highlights the rise in protocol redactions and predicts that, ██████████████████████████████████████████ will be entirely redacted between 2073 and 2136. A legitimate rationale for the redactions could ███ be found. A multipronged strategy against protocol redactions is required to maintain the integrity of science. AVAILABILITY This paper is partially redacted, but for the sake of ███████████, a version without any redactions can be found in the supplementary material.

Abstract
BACKGROUND Janus kinase (JAK) inhibitors, including baricitinib, block cytokine signaling and are effective disease-modifying treatments for several autoimmune diseases. Whether baricitinib preserves β-cell function in type 1 diabetes is unclear. METHODS In this phase 2, double-blind, randomized, placebo-controlled trial, we assigned patients with type 1 diabetes diagnosed during the previous 100 days to receive baricitinib (4 mg once per day) or matched placebo orally for 48 weeks. The primary outcome was the mean C-peptide level, determined from the area under the concentration-time curve, during a 2-hour mixed-meal tolerance test at week 48. Secondary outcomes included the change from baseline in the glycated hemoglobin level, the daily insulin dose, and measures of glycemic control assessed with the use of continuous glucose monitoring. RESULTS A total of 91 patients received baricitinib (60 patients) or placebo (31 patients). The median of the mixed-meal-stimulated mean C-peptide level at week 48 was 0.65 nmol per liter per minute (interquartile range, 0.31 to 0.82) in the baricitinib group and 0.43 nmol per liter per minute (interquartile range, 0.13 to 0.63) in the placebo group (P = 0.001). The mean daily insulin dose at 48 weeks was 0.41 U per kilogram of body weight per day (95% confidence interval [CI], 0.35 to 0.48) in the baricitinib group and 0.52 U per kilogram per day (95% CI, 0.44 to 0.60) in the placebo group. The levels of glycated hemoglobin were similar in the two trial groups. However, the mean coefficient of variation of the glucose level at 48 weeks, as measured by continuous glucose monitoring, was 29.6% (95% CI, 27.8 to 31.3) in the baricitinib group and 33.8% (95% CI, 31.5 to 36.2) in the placebo group. The frequency and severity of adverse events were similar in the two trial groups, and no serious adverse events were attributed to baricitinib or placebo. CONCLUSIONS In patients with type 1 diabetes of recent onset, daily treatment with baricitinib over 48 weeks appeared to preserve β-cell function as estimated by the mixed-meal-stimulated mean C-peptide level.

Abstract
Rheumatic diseases are often complicated by lung disease, commonly presenting as interstitial lung disease (ILD), with potentially detrimental consequences for patient survival. Although less frequent in pediatric patients, pulmonary involvement may be observed in almost all childhood-onset rheumatic conditions. The development of biological disease-modifying anti-rheumatic drugs has significantly improved clinical outcomes. However, disease remission is not always complete or long-lasting, and treatment may need to be discontinued due to adverse effects. A novel class of drugs, namely Janus kinase inhibitors (JAKis), has been proposed to provide a significant survival benefit for patients with rheumatic diseases. Despite the ample literature on the efficacy and safety of JAKis in rheumatic disease, only a few studies have investigated the effectiveness of these drugs in patients with pulmonary involvement, and only two case reports have presented results in pediatric patients. We provide an overview of the rationale for using JAKis in ILDs associated with rheumatic disease and summarize the main studies evaluating their efficacy in both adult and pediatric patients. The present review highlights the need for controlled long-term studies to assess the efficacy and safety of JAKis in pediatric rheumatic disease complicated by lung disease.

Abstract
Protein kinases play a major role in cellular activation processes, including signal transduction by diverse immunoreceptors. Given their roles in cell growth and death and in the production of inflammatory mediators, targeting kinases has proven to be an effective treatment strategy, initially as anticancer therapies, but shortly thereafter in immune-mediated diseases. Herein, we provide an overview of the status of small molecule inhibitors specifically generated to target protein kinases relevant to immune cell function, with an emphasis on those approved for the treatment of immune-mediated diseases. The development of inhibitors of Janus kinases that target cytokine receptor signalling has been a particularly active area, with Janus kinase inhibitors being approved for the treatment of multiple autoimmune and allergic diseases as well as COVID-19. In addition, TEC family kinase inhibitors (including Bruton's tyrosine kinase inhibitors) targeting antigen receptor signalling have been approved for haematological malignancies and graft versus host disease. This experience provides multiple important lessons regarding the importance (or not) of selectivity and the limits to which genetic information informs efficacy and safety. Many new agents are being generated, along with new approaches for targeting kinases.

Abstract
Several non-randomized clinical trials and retrospective studies have demonstrated encouraging efficacy and well-tolerated safety of tofacitinib in the treatment of alopecia areata. However, there are scarce data on a large cohort of patients with alopecia areata in long-term real-world practice. This single-centre, retrospective, observational cohort study included 126 patients with alopecia areata treated with tofacitinib between February 2021 and December 2022. The aims of this study are to evaluate drug survival, effectiveness and safety of tofacitinib for treatment of alopecia areata, and to identify potential factors influencing long-term outcomes. Median duration of treatment was 23.00 (interquartile range (IQR) 15.00, 47.25) weeks. Median all-cause survival time of 126 patients treated with tofacitinib was 44 weeks (95% confidence interval (95% CI) 36.3, 51.7), and the all-cause drug retention rate at 12 weeks, 24 weeks and 48 weeks were 90.0%, 66.4% and 42.3%, respectively. The most common reason for discontinuation was complete remission/satisfaction. A total of 80 patients treated with tofacitinib for over 6 months were included in the efficacy analysis, the overall complete response rate at 24 weeks was 33.8% (27/80). No life-threatening serious adverse events occurred. Sex is an independent risk factor in predicting patient outcomes. This real-world study confirmed the high effectiveness and acceptable safety profile of tofacitinib in alopecia areata, with a satisfactory drug survival rate, and provides supporting data for the clinical application of tofacitinib in Chinese patients with alopecia areata.

Abstract
Suppressor of cytokine signaling 1 (SOCS1) is a negative regulator of cytokine signaling that inhibits the activation of Janus kinases. A human disease caused by SOCS1 haploinsufficiency was first identified in 2020. To date, 18 cases of SOCS1 haploinsufficiency have been described. These patients experience enhanced activation of leukocytes and multiorgan system immunodysregulation, with immune-mediated cytopenia as the most common feature. In this review, the authors provide an overview on the biology of SOCS1 and summarize their knowledge of SOCS1 haploinsufficiency including genetics and clinical manifestations. They discuss the available treatment experience and outline an approach for the evaluation of suspected cases.

Abstract
Over the last decade, there has been an increase in the use of targeted therapy using small molecules such as Janus kinase (JAK) inhibitors. Since the introduction of ruxolitinib, the first non-selective JAK inhibitor approved for use in myelofibrosis, many other JAK inhibitors have been tried in a wide spectrum of immune-mediated disorders. Although various trials have shown the promising efficacy of JAK inhibitors in immune-mediated inflammatory disorders (IMIDs), there is a growing concern over the major cardiovascular events and malignancies associated with the use of these molecules in older adults, particularly those over 65 years of age. In this review, we aim to discuss the immunology of the JAK-STAT pathway, the scope of use of JAK inhibitors, and their safety in paediatric practice. Here, we discuss high-quality evidence favouring the use of JAK inhibitors in children with juvenile idiopathic arthritis (JIA) who are refractory to one or more conventional/biological disease-modifying drugs, demonstrated in two randomised controlled trials (RCTs). In addition to JIA, there are reports favouring the role of JAK inhibitors in other IMIDs such as systemic-onset JIA and interferonopathies. Thus far, the existing literature suggests an acceptable safety profile for JAK inhibitors in children. With the expanding scope of JAK inhibitors in a wide range of IMIDs in children, there is a significant need for long-term close vigilance for any potential harm.

Abstract
Polyarticular course juvenile idiopathic arthritis (pcJIA) is a form of arthritis that affects at least five joints at a time and presents before the age of 16. Its most common symptoms are pain, swelling, redness, and a limited range of motion, making it incredibly difficult for patients diagnosed to function in daily life. Historically, the leading treatment options have consisted of non-steroidal anti-inflammatory drugs (NSAIDs) and disease-modifying antirheumatic drugs (DMARDs) such as methotrexate. However, these drugs have serious toxic side effects associated with long-term use in addition to being ineffective in refractory cases. Recently, small molecule biologics have emerged as an alternate treatment to pcJIA. Tofacitinib is a small molecule JAK inhibitor that blocks the JAK/STAT cascade and decreases the transcription of genes responsible for immune function. We conducted a risk-benefit analysis to determine the viability of tofacitinib as a treatment for pcJIA. In our review, we found the side effect profile of tofacitinib to be relatively mild, with many of the serious adverse side effects occurring in those immunocompromised and those with impaired renal and hepatic metabolism. Overall, we have determined that tofacitinib has the potential to be effective in reducing flare-ups and lowering erythrocyte sedimentation rate (ESR) in immunocompetent patients with pcJIA. Additionally, our review has found that tofacitinib has the potential to be effective in patients who are refractory to traditional treatment. However, large-scale clinical trials are needed to determine if this effect holds true in younger pediatric populations, as limited data surrounds this demographic.

Abstract
OBJECTIVE To describe the efficacy and safety data of children with polyarticular-course juvenile idiopathic arthritis (pcJIA) treated with abatacept (ABA) + methotrexate (MTX) or ABA monotherapy when prior MTX use was either ineffective or not tolerated. METHODS Posthoc analysis of 2 phase III trials of subcutaneous (SC) and intravenous (IV) ABA over 2 years in patients with pcJIA (aged 2-17 years). Patients were stratified by treatment with ABA + MTX or ABA monotherapy and further by prior biologic use. Efficacy outcomes included JIA-American College of Rheumatology (JIA-ACR) responses, Juvenile Arthritis Disease Activity Score in 27 joints using C-reactive protein (JADAS27-CRP), and safety. Descriptive pharmacokinetic analyses were also performed. RESULTS Efficacy responses (JIA-ACR and JADAS27-CRP) were similar between patients receiving ABA + MTX (n = 310) or ABA monotherapy (n = 99) and persisted over 2 years. Clinical response rates were similar in biologic-naïve patients and prior biologic users; this was independent of MTX use. Across both studies, ABA + MTX and ABA monotherapy displayed similar safety profiles. Pharmacokinetic results revealed similar minimum steady-state trough ABA concentrations between studies. Further, baseline MTX did not influence ABA clearance and was not a significant predictor of JIA-ACR responses. CONCLUSION ABA monotherapy (SC and IV) was effective and well tolerated in children with pcJIA when prior MTX use was ineffective or not tolerated. Treatment effects of ABA appear to be independent of MTX coadministration. Consequently, ABA monotherapy can be considered for those with prior biologic therapy if MTX use is inappropriate.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children and comprises of multiple subtypes. The most relevant disease subtypes, grouped upon current insight in disease mechanisms, are nonsystemic (oligo- and polyarticular) JIA and systemic JIA (sJIA). In this review, we summarize some of the main proposed mechanisms of disease in both nonsystemic and sJIA and discuss how current therapeutic modalities target some of the pathogenic immune pathways. Chronic inflammation in nonsystemic JIA is the result of a complex interplay between effector and regulatory immune cell subsets, with adaptive immune cells, specifically T-cell subsets and antigen-presenting cells, in a central role. There is, however, also innate immune cell contribution. SJIA is nowadays recognized as an acquired chronic inflammatory disorder with striking autoinflammatory features in the first phase of the disease. Some sJIA patients develop a refractory disease course, with indications for involvement of adaptive immune pathways as well. Currently, therapeutic strategies are directed at suppressing effector mechanisms in both non-systemic and sJIA. These strategies are often not yet optimally tuned nor timed to the known active mechanisms of disease in individual patients in both non-systemic and sJIA. We discuss current treatment strategies in JIA, specifically the 'Step-up' and 'Treat to Target approach' and explore how increased insight into the biology of disease may translate into future more targeted strategies for this chronic inflammatory disease at relevant time points: preclinical disease, active disease, and clinically inactive disease.

Abstract
Enthesitis-related arthritis (ERA) represents 5-30% of all cases of juvenile idiopathic arthritis (JIA) and belongs to the spectrum of the disorders included in the group of juvenile spondyloarthritis. In the last decade, there have been considerable advances in the classification, diagnosis, monitoring, and treatment of ERA. New provisional criteria for ERA have been recently proposed by the Paediatric Rheumatology INternational Trials Organisation, as part of a wider revision of the International League of Associations for Rheumatology criteria for JIA. The increased use of magnetic resonance imaging has shown that a high proportion of patients with ERA present a subclinical axial disease. Diverse instruments can be used to assess the disease activity of ERA. The therapeutic recommendations for ERA are comparable to those applied to other non-systemic JIA categories, unless axial disease and/or enthesitis are present. In such cases, the early use of a TNF-alpha inhibitor is recommended. Novel treatment agents are promising, including IL-17/IL-23 or JAK/STAT pathways blockers.

Abstract
OBJECTIVE Stakeholders met to address persistent challenges facing the development of therapeutics for polyarticular juvenile idiopathic arthritis (pJIA), which result in fewer approved therapies for children with pJIA than adults with rheumatoid arthritis (RA) and long lag times from adult RA approval to pediatric labeling. Ensuring that new medications are authorized in a timely manner to meet the needs of JIA patients worldwide is critically important to multiple stakeholders. METHODS The Food and Drug Administration in collaboration with the University of Maryland Center for Regulatory Science and Innovation held a public workshop entitled "Accelerating Drug Development for pJIA" on October 2, 2019, to address challenges surrounding access to new medications for children and adolescents with pJIA. Regulatory, academic, and industry stakeholders, as well as patient representatives, participated in the workshop, which consisted of 4 sessions, including panel discussions. RESULTS The workshop facilitated broad public discussion of challenges facing the development of pJIA therapeutics, highlighting areas of need and outlining opportunities to expedite development, while underscoring the necessity of close collaboration between all stakeholders, including patients and families. CONCLUSION This report summarizes key aspects of the workshop, including the appropriate application of innovative approaches to the development of pJIA therapeutics, including extrapolation, to address current challenges and provide timely access to newer safe and effective treatments. Long-term safety assessment is of pressing concern to stakeholders and cannot be fully extrapolated from adult studies but requires consistent postmarketing long-term follow-up.

Abstract
OBJECTIVE The goal of juvenile idiopathic arthritis (JIA) treatment is to maintain clinical remission. It is also important to reduce drug exposure, whenever possible, in order to avoid or decrease potential side effects. We aimed to analyze remission survival after systemic treatment withdrawal and to determine which factors can influence it. METHODS We conducted a multicenter, observational, longitudinal study. All patients included had a diagnosis of JIA. We analyzed remission survival using Kaplan-Meier curves according to the systemic treatment received (methotrexate [MTX] alone or in combination with biologic disease-modifying antirheumatic drugs [bDMARDs]) and JIA subgroups (oligoarticular and polyarticular course, juvenile spondyloarthritis, and systemic JIA). In addition, risk factors were examined using multivariate analysis. RESULTS We included 404 patients with JIA; 370 of them (92%) had received systemic treatment at some point and half of them (185 patients) had withdrawn on at least 1 occasion. There were 110 patients who flared (59%) with a median time of 2.3 years. There were no differences in remission survival between JIA subcategories. Twenty-nine percent of patients with JIA who received MTX and bDMARDs, in which MTX alone was withdrawn, flared; median time to flare of 6.3 years. However, if only the bDMARD was withdrawn, flares occurred 57% of the time; median time to flare of 1.1 years. CONCLUSION Flares are frequent when systemic treatment is withdrawn, and uveitis or joint injections could be related risk factors. In MTX and biologic-naïve patients, the frequency of flares occurred in more than half of patients, although they were less frequent when clinical remission lasted for > 1 year.

Abstract
Juvenile idiopathic arthritis (JIA) comprises a group of heterogenous disorders characterized by childhood-onset chronic joint inflammation. It is the most common rheumatologic disease in the pediatric population and an important cause of chronic illness in children. Early recognition and treatment are vital to prevent sequelae of uncontrolled inflammation on the developing skeleton. JIA can have significant complications that general pediatricians should be aware of, especially uveitis, which can be insidious and asymptomatic in very young children, and macrophage activation syndrome, which can be life-threatening if not recognized and appropriately treated. Although advances have been made in the past few decades, the etiology of JIA remains incompletely understood. Efforts are underway to refine the classification of JIA. The currently accepted classification scheme identifies subsets of JIA that are important clinically in terms of prognosis and tailoring treatment approaches. However, it is limited in identifying homogenous groups of children with early childhood onset and antinuclear antibody positivity, which may have different pathogenic mechanisms that could be important in developing more targeted and effective treatment approaches in the future. Treatment strategies for JIA have changed significantly in recent years with the availability of multiple newer targeted therapies, often modeled after medications used in adult-onset forms of arthritis. These treatments, and likely many others to come, have markedly improved symptom control and reduced complications in patients with JIA.

Abstract
Cardiovascular involvement in juvenile rheumatic diseases is the primary manifestation in paediatric vasculitis and a major organ manifestation in paediatric connective tissue diseases. Though coronary vasculitis is the prototypical manifestation of Kawasaki disease, it can also be seen in patients with polyarteritis nodosa. Pericarditis is the most common manifestation seen in juvenile rheumatic diseases like systemic onset JIA, and lupus. Cardiac tamponade, valvular insufficiency, aortic root dilatation and arrhythmias are seen rarely. Cardiac involvement is often recognized late in children. The development of cardiac disease in juvenile systemic sclerosis is associated with a poor outcome. In long term, childhood onset of rheumatic diseases predisposes to diastolic dysfunction and premature atherosclerosis during adulthood. Key Points • Pericarditis is the most common cardiac manifestation in SLE and can lead to tamponade. • Conduction defects are common in juvenile mixed connective tissue disease and systemic sclerosis. • Pulmonary hypertension is a significant contributor to mortality in juvenile systemic sclerosis. • In Kawasaki disease, early treatment can reduce risk of coronary artery aneurysms.

Abstract
Alopecia areata (AA) is a common cause of hair loss in children. Despite numerous therapeutic options for paediatric AA, none have been found to be both effective and safe. Recent studies have demonstrated the efficacy and safety of the Janus kinase (JAK) inhibitor tofacitinib in adult patients with AA, whereas data on paediatric patients with AA in real-world practice are limited. This was a single-centre, retrospective study that included 11 pre-adolescent patients with AA treated with tofacitinib between December 2021 and September 2022. Clinical characteristics of patients, clinical response and adverse events were evaluated. Overall, 82% (9/11) of patients experienced hair regrowth and 64% (7/11) of patients experienced over 50% improvement in their Severity of Alopecia Tool (SALT) scores. Adverse events were mild. In the literature, tofacitinib has been used to treat AA in 31 children ≤12 years of age who failed to respond to prior treatments. Eighty-seven percent (27/31) of these patients showed significant responses based on changes in their SALT scores. This case series demonstrates that oral tofacitinib is an effective and safe treatment option for paediatric AA, particularly for children who have failed to respond to traditional treatments or are not suitable for such treatments.

Abstract
It is well known that fatigue is a highly disabling symptom commonly observed in inflammatory rheumatic diseases (IRDs). Fatigue is strongly associated with a poor quality of life and seems to be an independent predictor of job loss and disability in patients with different rheumatic diseases. Although the pathogenesis of fatigue remains unclear, indirect data suggest the cooperation of the immune system, the central and autonomic nervous system, and the neuroendocrine system in the induction and sustainment of fatigue in chronic diseases. Fatigue does not correspond with disease activity and its mechanism in IRDs. It is suggested that it may change over time and vary between individuals. Abnormal production of pro-inflammatory cytokines such as interleukin-6 (IL-6), interferons (IFNs), granulocyte-macrophage colony-stimulating factor (GM-CSF), TNF, IL-15, IL-17 play a role in both IRDs and subsequent fatigue development. Some of these cytokines such as IL-6, IFNs, GM-CSF, and common gamma-chain cytokines (IL-15, IL-2, and IL-7) activate the Janus Kinases (JAKs) family of intracellular tyrosine kinases. Therapy blocking JAKs (JAK inhibitors - JAKi) has been recently proven to be an effective approach for IRDs treatment, more efficient in pain reduction than anti-TNF. Therefore, the administration of JAKi to IRDs patients experiencing fatigue may find rational implications as a therapeutic modulator not only of disease inflammatory symptoms but also fatigue with its components like pain and neuropsychiatric features as well. In this review, we demonstrate the latest information on the mechanisms of fatigue in rheumatic diseases and the potential effect of JAKi on fatigue reduction.

Abstract
Therapeutic options for the treatment of pediatric inflammatory bowel disease include aminosalicylates, enteral nutrition, corticosteroids, immunomodulators, biologics, and emerging small molecule agents. Infectious risk due to systemic immunosuppression should be mitigated by appropriate screening before therapy initiation. Rare but serious malignancies have been associated with thiopurine use alone and in combination with anti-tumor necrosis factor agents, often in the setting of a primary Epstein-Barr virus infection. Potential agent-specific adverse events such as cytopenias, hepatotoxicity, and nephrotoxicity warrant regular clinical and laboratory monitoring.

Abstract
Fibrodysplasia ossificans progressive (FOP) is an ultra-rare genetic disorder that is caused by a mutation in the ACVR1 gene and provokes severe heterotopic ossification. Since flares of the disease are associated with inflammation, it is assumed that JAK inhibitors can control active FOP due to blocking multiple signaling pathways.

Baricitinib in juvenile idiopathic arthritis: an international, phase 3, randomised, double-blind, placebo-controlled, withdrawal, efficacy, and safety trial. Lancet 2023; 402:555-570. [PMID: 37423231 DOI: 10.1016/s0140-6736(23)00921-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 04/25/2023] [Accepted: 05/02/2023] [Indexed: 07/11/2023]
Abstract
BACKGROUND Juvenile idiopathic arthritis can be refractory to some or all treatment regimens, therefore new medications are needed to treat this population. This trial assessed the efficacy and safety of baricitinib, an oral Janus kinase 1/2-selective inhibitor, versus placebo in patients with juvenile idiopathic arthritis. METHODS This phase 3, randomised, double-blind, placebo-controlled, withdrawal, efficacy, and safety trial was conducted in 75 centres in 20 countries. We enrolled patients (aged 2 to <18 years) with polyarticular juvenile idiopathic arthritis (positive or negative for rheumatoid factor), extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis, or juvenile psoriatic arthritis, and an inadequate response (after ≥12 weeks of treatment) or intolerance to one or more conventional synthetic or biologic disease-modifying antirheumatic drugs (DMARDs). The trial consisted of a 2-week safety and pharmacokinetic period, a 12-week open-label lead-in period (10 weeks for the safety and pharmacokinetic subcohort), and an up to 32-week placebo-controlled double-blind withdrawal period. After age-based dosing was established in the safety and pharmacokinetic period, patients received a once-daily 4 mg adult-equivalent dose of baricitinib (tablets or suspension) in the open-label lead-in period. Patients meeting Juvenile Idiopathic Arthritis-American College of Rheumatology (JIA-ACR) 30 criteria (JIA-ACR30 responders) at the end of the open-label lead-in (week 12) were eligible for random assignment (1:1) to receive placebo or continue receiving baricitinib, and remained in the double-blind withdrawal period until disease flare or up to the end of the double-blind withdrawal period (week 44). Patients and any personnel interacting directly with patients or sites were masked to group assignment. The primary endpoint was time to disease flare during the double-blind withdrawal period and was assessed in the intention-to-treat population of all randomly assigned patients. Safety was assessed in all patients who received at least one dose of baricitinib throughout the three trial periods. For adverse events in the double-blind withdrawal period, exposure-adjusted incidence rates were calculated. The trial was registered on ClinicalTrials.gov, NCT03773978, and is completed. FINDINGS Between Dec 17, 2018 and March 3, 2021, 220 patients were enrolled and received at least one dose of baricitinib (152 [69%] girls and 68 [31%] boys; median age 14·0 years [IQR 12·0-16·0]). 219 patients received baricitinib in the open-label lead-in period, of whom 163 (74%) had at least a JIA-ACR30 response at week 12 and were randomly assigned to placebo (n=81) or baricitinib (n=82) in the double-blind withdrawal period. Time to disease flare was significantly shorter with placebo versus baricitinib (hazard ratio 0·241 [95% CI 0·128-0·453], p<0·0001). Median time to flare was 27·14 weeks (95% CI 15·29-not estimable) in the placebo group, and not evaluable for patients in the baricitinib group (<50% had a flare event). Six (3%) of 220 patients had serious adverse events during the safety and pharmacokinetic period or open-label lead-in period. In the double-blind withdrawal period, serious adverse events were reported in four (5%) of 82 patients (incidence rate [IR] 9·7 [95% CI 2·7-24·9] per 100 patient-years at risk) in the baricitinib group and three (4%) of 81 (IR 10·2 [2·1-29·7]) in the placebo group. Treatment-emergent infections were reported during the safety and pharmacokinetic or open-label lead-in period in 55 (25%) of 220 patients, and during the double-blind withdrawal period in 31 (38%) of 82 (IR 102·1 [95% CI 69·3-144·9]) in the baricitinib group and 15 (19%) of 81 (IR 59·0 [33·0-97·3]) in the placebo group. Pulmonary embolism was reported as a serious adverse event in one patient (1%; IR 2·4 [95% CI 0·1-13·3]) in the baricitinib group in the double-blind withdrawal period, which was judged to be related to study treatment. INTERPRETATION Baricitinib was efficacious with an acceptable safety profile in the treatment of polyarticular juvenile idiopathic arthritis, extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis, and juvenile psoriatic arthritis, after inadequate response or intolerance to standard therapy.

[PMID: 37558928 DOI: 10.1007/s00296-023-05418-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Accepted: 08/02/2023] [Indexed: 08/11/2023]
Abstract
BACKGROUND Inflammatory skin diseases (ISDs), are characterized by dysregulated activation of innate and adaptive immune systems, with inflammatory cytokines playing a crucial role in their pathogenesis. OBJECTIVES This study aimed to investigate the involvement of Janus kinase/signal transduction and activator of transcription (JAK/STAT) signaling pathway in the pathogenesis of ISDs. METHODS The study analyzed a total of 117 skin biopsies, comprising 31 from pyoderma gangrenosum (PG), 25 from hidradenitis suppurativa (HS), 35 from psoriasis patients, and 26 from control subjects. To assess the expression levels of JAK/STAT pathway components, immunohistochemical staining was performed on both the dermal and epidermal layers of the skin. The Histo score (H score) was utilized as the immunoexpression score to evaluate the staining intensity. RESULTS The results indicated that all components of the JAK/STAT signaling pathway, except JAK2 and STAT6 in PG, JAK1, STAT4, and STAT6 in HS, and JAK1 in psoriasis, were overexpressed in the dermal skin compared to the control group (p < 0.05). Psoriatic skin had higher expression of STAT6 than both PG and HS and higher expression of JAK2 than PG (p < 0.05). Additionally, HS biopsies had higher expression of JAK2 and STAT6 compared to PG (p < 0.05). JAK1 expression was higher in PG than in HS, psoriasis, and the control group (mean H score was 265.8, 184.8, 191.4, and 113.1, p < 0.05, respectively). CONCLUSIONS This study provides new insights into the potential contribution of the JAK/STAT pathway to the pathogenesis of ISDs. The findings suggest that targeting this pathway could be a promising therapeutic strategy for treating these disorders.

Abstract
Juvenile idiopathic arthritis (JIA) is a heterogeneous group of diseases with probably differential underlying physiopathology. Despite the revolutionary era of biologics, some patients remain difficult to treat because of disease severity, drug adverse events, drug allergy or association with severe comorbidities, i.e., uveitis, interstitial lung disease and macrophagic activation syndrome. Janus Kinase (JAK) inhibitors are small molecules that target JAK/Signal Transducers and Activators of Transcription (STAT) pathways, which could then prevent the activity of several proinflammatory cytokines. They may provide a useful alternative in these cases of JIA or in patients actually affected by Mendelian disorders mimicking JIA, such as type I interferonopathies with joint involvement, and might be the bridge for haematopoietic stem cell transplantation in these disabling conditions. As these treatments may have side effects that should not be ignored, ongoing and further controlled studies are still needed to provide data underlying long-term safety considerations in children and delineate subsets of JIA patients that will benefit from these promising treatments.
