Horneff G, Minden K, Rolland C, Daly ACH, Borlenghi C, Ruperto N. Efficacy and safety of TNF inhibitors in the treatment of juvenile idiopathic arthritis: a systematic literature review. Pediatr Rheumatol Online J 2023; 21:20. [PMID: 36829225 PMCID: PMC9951426 DOI: 10.1186/s12969-023-00798-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Accepted: 01/29/2023] [Indexed: 02/26/2023] Open
Abstract
OBJECTIVE A systematic literature review was conducted to summarize efficacy and safety data from studies that evaluated tumor necrosis factor inhibitors in patients with juvenile idiopathic arthritis (JIA). METHODS Relevant publications were identified via online searches (cutoff: March 16, 2021). After screening search results, outcome data were extracted if the treatment arm included ≥ 30 patients. Outcomes were described narratively, with efficacy assessed by JIA-American College of Rheumatology (ACR) response criteria and safety assessed by the incidence of serious adverse events (SAEs) per 100 patient-years (100PY). RESULTS Among 87 relevant publications included in the qualitative synthesis, 19 publications described 13 clinical trials. Across the 13 trials, the percentages of patients who achieved JIA-ACR30/50/70/90 responses at Week 12 with adalimumab ranged 71-94%, 68-90%, 55-61%, and 39-42%, respectively; with etanercept (Week 12), 73-94%, 53-78%, 36-59%, and 28%; with golimumab (Week 16), 89%, 79%, 66%, and 36%; and with infliximab (Week 14), 64%, 50%, and 22% (JIA-ACR90 not reported). SAE incidence across all time points ranged 0-13.7 SAE/100PY for adalimumab, 0-20.0 SAE/100PY for etanercept, and 10.4-24.3 SAE/100PY for golimumab (1 study). SAE incidence could not be estimated from the 2 infliximab publications. CONCLUSION Tumor necrosis factor inhibitors are effective and well tolerated in the treatment of JIA, but additional evidence from head-to-head studies and over longer periods of time, especially in the context of the transition from pediatric to adult care, would be useful.

Biologic Disease-Modifying and Other Anti-Rheumatic Drugs Use in Patients with Moderate-to-Severe Juvenile Idiopathic Arthritis Based on a Japanese Nationwide Claims Database. Ther Clin Risk Manag 2022; 18:843-853. [PMID: 36046102 PMCID: PMC9422327 DOI: 10.2147/tcrm.s375890] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 08/08/2022] [Indexed: 11/25/2022] Open
Abstract
Purpose Biologic disease-modifying anti-rheumatic drugs (bDMARDs) are highly effective and safe against juvenile idiopathic arthritis (JIA), which is classified into systemic JIA (sJIA) and the other JIA categories (non-sJIA) according to differences in clinical symptoms and pathophysiology. The purpose of the current study was to investigate trends in patterns of prescribing bDMARDs for moderate-to-severe JIA using a relatively large sample size in Japan. Patients and Methods A descriptive epidemiological study based on a nationwide claims database in Japan was conducted from 2012 to 2018 using the “JMDC Claims Database” to explain annual changes based on the number of patients prescribed bDMARDs. Study drugs were identified based on the Anatomical Therapeutic Chemical codes, such as methotrexate, glucocorticoids, non-steroidal anti-inflammatory drugs, and bDMARDs. Results From a database of 6,862,244 patients, the following exclusion criteria were applied: aged ≥16 years, without “M08” in their ICD-10 code as disease, and missing the information of prescription date in the database during the study period, resulting in a final number of 111 JIA patients. We found an increasing trend for adalimumab and tocilizumab and a decreasing trend for methotrexate. Differences in medication use between sJIA and non-sJIA patients were also evident, being consistent with national and international guidelines. Conclusion Although the introduction of bDMARDs has markedly improved the efficacy of JIA therapy, there are still many short- and long-term safety issues to be examined, including the risk of infection and potential risk of associated malignancy. Future studies are needed to clarify these issues.

Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children. With the gradual expansion of the incidence of JIA in the population, the pathogenesis and treatment of JIA were further explored and analyzed, and JIA has achieved some success in drug therapy. DATA SOURCES A systemic literature search was conducted on PubMed, Cochrane Library, EMBASE, ISI Web of Science, the US National Institutes of Health Ongoing Trials Register, and the EU Clinical Trials Register. Through the searching of clinical trials of JIA in recent years, we summarized the progress of the clinical treatment of JIA. RESULTS The main treatment drugs for JIA include non-steroidal anti-inflammatory drugs, glucocorticoids, disease-modifying antirheumatic drugs and biological agents. So far, a variety of biological agents targeting the cytokines and receptors involved in its pathogenesis have been gradually approved for JIA in many countries. The application of biological agents in JIA showed good efficacy and safety, bringing unprecedented experience to children and adolescents with JIA. CONCLUSIONS The potential and advantages of biologic agents in the treatment of JIA are significant, and the application of biologic agents in the treatment of JIA will be more and more common.

Long-Term Outcomes of Pediatric Idiopathic Intermediate Uveitis. Am J Ophthalmol 2022; 237:41-48.

Abstract
PURPOSE To describe the course of childhood-onset intermediate uveitis without associated systemic disease, and investigate determinants of outcomes. DESIGN A retrospective clinical cohort study METHODS: This study was conducted in an institutional setting. A total of 125 children (221 eyes) aged 16 years and less participated. Outcomes of interest were visual acuity, severity of inflammation, and the occurrence of sight-threatening complications. Variables examined included age and clinical findings at presentation, treatment, and duration of follow-up. Multivariable analysis was undertaken to investigate potential predictors of outcomes. RESULTS The median follow-up duration was 57 months. At presentation, best-corrected visual acuity worse than 20/160 was recorded in 11 (4.4%) eyes and significant vitreous haze (≥2+Standardisation of Uveitis Nomenclature (SUN)) in 35 (14%) eyes. Corticosteroid-sparing agents were used in 41 children (33%), with methotrexate most commonly used (27 children, 21.6%). The most frequent complications were raised intraocular pressure (n = 65; 29.4%), cataract (n = 41; 18.5%), and cystoid macular edema (n = 29; 13.1%). At the last visit, 116 (92.8%) patients achieved best-corrected vision of 20/40 or better with quiescent uveitis. The absence of the use of a steroid-sparing immunomodulatory agent was the strongest predictive factor for the development of new macular edema (odds ratio = 6.3, 95% CI = 2.3-16.9, P < .001) or glaucoma (odds ratio = 6.6, 95% CI = 2.5-17.9, P < .001) over the period of observation. CONCLUSIONS The visual outcomes of childhood-onset idiopathic intermediate uveitis are favorable. The frequency of sight-threatening sequelae of inflammation, which confer a lifelong risk of further visual loss, is high. The use of immunomodulatory therapy is associated with a lower risk of developing macular edema and ocular hypertension.

The benefit–risk balance for biological agents in juvenile idiopathic arthritis: a meta-analysis of randomized clinical trials. Rheumatology (Oxford) 2020; 59:2226-2236. [DOI: 10.1093/rheumatology/keaa170] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Revised: 02/05/2020] [Accepted: 02/22/2020] [Indexed: 12/28/2022] Open
Abstract
Abstract
Objective
To assess the net benefit of biological agents (BA) used in JIA.
Methods
We systematically searched databases up to March 2019 for randomized controlled trials (RCT) performed in JIA disease. Separate random-effects meta-analyses were conducted for efficacy (ACR paediatric score 30%, ACRpedi30) and serious adverse events for safety. In order to standardize the baseline risk, we performed a meta-analysis of baseline risk in the control group (for both efficacy and safety meta-analysis). The net benefit was determined as the risk difference of efficacy subtracted by the risk difference of safety.
Results
We included 19 trials: 11 parallel RCTs (754 patients) and 8 withdrawal RCTs (704 patients). The net benefit ranged from 2.4% (adalimumab) to 17.6% (etanercept), and from 2.4% (etanercept) to 36.7%, (abatacept) in parallel and withdrawal trials assessing non-systemic JIA, respectively. In the systemic JIA category, the net benefit ranged from 22.8% (rilonacept) to 70.3% (canakinumab), and from 32.3% (canakinumab) to 58.2% (tocilizumab) in parallel and withdrawal trials, respectively.
Conclusion
The results suggest that a greater number of patients experienced therapeutic success without serious adverse events in the systemic onset JIA category compared with the BAs for non-systemic JIA categories. Baseline risk, design of trial and JIA categories impact the measure of net benefit of BAs in JIA patients.

Abstract
BACKGROUND Psoriasis, psoriatic arthritis, spondyloarthritis, rheumatoid arthritis, ulcerative colitis, and Crohn disease share similar underlying pathophysiological processes, providing the opportunity to treat the patients using similar biological therapies. Failure of biological treatments due to underexposure can be managed by therapeutic drug monitoring. Adjusting the treatment based on pharmacokinetic monitoring can be further improved by taking pharmacodynamic parameters such as clinical and molecular markers into account. METHODS Here, we critically evaluate the existing evidence, the hurdles to be taken, and the opportunities for a widespread implementation of pharmacodynamic monitoring. RESULTS Pharmacodynamic monitoring typically is the monitoring of biochemical markers. A pharmacodynamic marker preferably is specific for the pharmacological action of a drug, but most of the time nonspecific pharmacodynamic markers are used, such as C-reactive protein and the erythrocyte sedimentation rate. Clinical pharmacodynamic markers typically evaluate physical variables or symptoms. Although physician-reported outcomes have been studied for a longer time and often have been shown to correlate well with molecular pharmacodynamic markers and treatment outcomes, the introduction of mobile health or mHealth technologies caused a shift toward patient-reported outcomes, with the associated challenge to consistently reflect the inflammatory state, thereby preventing undertreatment or unnecessary overdosing of patients. CONCLUSIONS The primary goal of pharmacodynamic monitoring is to optimize the response, but it can also have an impact on safety, costs, patient adherence, etc. Ideally, the constant remote monitoring of patient-reported disease activity is expected to become the standard, facilitated by mHealth technologies.

Abstract
OBJECTIVE To determine the frequency, time to flare, and predictors of disease flare upon withdrawal of anti-tumor necrosis factor (anti-TNF) therapy in children with polyarticular forms of juvenile idiopathic arthritis (JIA) who demonstrated ≥6 months of continuous clinically inactive disease. METHODS In 16 centers 137 patients with clinically inactive JIA who were receiving anti-TNF therapy (42% of whom were also receiving methotrexate [MTX]) were prospectively followed up. If the disease remained clinically inactive for the initial 6 months of the study, anti-TNF was stopped and patients were assessed for flare at 1, 2, 3, 4, 6, and 8 months. Life-table analysis, t-tests, chi-square test, and Cox regression analysis were used to identify independent variables that could significantly predict flare by 8 months or time to flare. RESULTS Of 137 patients, 106 (77%) maintained clinically inactive disease while receiving anti-TNF therapy for the initial 6 months and were included in the phase of the study in which anti-TNF therapy was stopped. Stopping anti-TNF resulted in disease flare in 39 (37%) of 106 patients by 8 months. The mean/median ± SEM time to flare was 212/250 ± 9.77 days. Patients with shorter disease duration at enrollment, older age at onset and diagnosis, shorter disease duration prior to experiencing clinically inactive disease, and shorter time from onset of clinically inactive disease to enrollment were found to have significantly lower hazard ratios for likelihood of flare by 8 months (P < 0.05). CONCLUSION Over one-third of patients with polyarticular JIA with sustained clinically inactive disease will experience a flare by 8 months after discontinuation of anti-TNF therapy. Several predictors of lower likelihood of flare were identified.

Abstract
PURPOSE To describe the treatment and outcomes of a cohort of pediatric intermediate uveitis (IU) patients, with a particular focus on the use of immunomodulatory therapy (IMT). METHODS The disease course, treatment, and outcomes of 39 pediatric IU patients treated in the Uveitis Clinic at the University of Utah from 1999 to 2012 were reviewed, retrospectively. RESULTS Mean age at presentation was 7.7 years (SD 3.1). In total, 95% had bilateral involvement. Out of 77 total eyes involved, the most frequent disease complications were ocular hypertension (0.71 events per person year, PPY), cataracts (events PPY = 0.39), and cystoid macular edema (events PPY = 0.33). A total of 20 patients received IMT; 19/20 were tapered off systemic corticosteroids without a uveitis recurrence; 75% of eyes had inactive disease at final follow-up (mean 37 months). CONCLUSIONS The use of IMT, including biologic therapies, may effectively manage disease inflammation and reduce steroid dosages in pediatric IU patients.

Abstract
Psoriatic arthritis (PsA) is a chronic, progressive, inflammatory spondyloarthropathy that affects approximately one-third of patients with all types of psoriasis. Dermatologists are in a unique position to recognize early symptoms of PsA, initiate appropriate therapy, and prevent development of further disability. The course of PsA can be modulated by immunosuppressive therapy; patients with moderate-to-severe disease require aggressive management with medications proven to halt disease progression. It is essential for the dermatologist to understand the safety, tolerability, efficacy, cost, and potential to halt disease progression with available medications for this relatively common and potentially disabling disease.

Abstract
The identification and clinical demonstration of efficacy and safety of osteo- and chondro-protective drugs are met with certain difficulties. During the last few decades, the pharmaceutical industry has, in the field of rheumatology, experienced disappointments associated with the development of disease modification. Today, the vast amount of patients suffering from serious, chronic joint diseases can only be offered treatments aimed at improving symptoms, such as pain and acute inflammation, and are not aimed at protecting the joint tissue. This huge, unmet medical need has been the driver behind the development of improved analytical techniques allowing better and more efficient clinical trial design, implementation and analysis. With this review, we aim to provide a brief and general overview of biochemical markers of joint tissue, with special focus on neoepitopes. Furthermore, we highlight recent studies applying biochemical markers in joint degenerative diseases. These disorders, including osteoarthritis, rheumatoid arthritis and spondyloarthropathies, are the most predominant disorders in Europe and the USA, and have enormous socioeconomical impact.

Abstract
OBJECTIVES The influence of proteolytic-antiproteolytic enzymes and prooxidative-anti-oxidative factors on proteoglycan alterations in children with juvenile idiopathic arthritis (JIA) was evaluated in this study. DESIGN, METHODS, RESULTS Plasma and urinary glycosaminoglycans (GAGs), as well as plasma levels of matrix metalloproteinases (MMPs) (MMP-3, MMP-10), tissue inhibitors of metalloproteinases (TIMPs) (TIMP-1, TIMP-2), total oxidative status (TOS) and total antioxidative status (TAS), were quantified in samples obtained from 30 healthy subjects and 30 JIA patients before and after treatment. Significantly decreased plasma and urinary concentration of GAGs in JIA patients before treatment was observed. Therapy resulted in an increase in the concentration of the above listed parameters. However, the plasma GAG level still remained significantly lower compared to that in controls. Increased levels of MMP-3 and TIMP-1 in both JIA patient groups were recorded. The plasma MMP-10 and TIMP-2 concentrations in untreated patients were significantly decreased. Anti-inflammatory treatment led to normalization of these parameter concentrations. Significant increase of TOS but decrease of TAS was found in the blood of untreated patients. The treatment resulted only in the normalization of TOS concentration. We have revealed a significant correlation between plasma GAGs and: MMP-3 (r=0.54), TOS (r=0.64) and urinary GAGs (r=0.55), respectively. CONCLUSIONS Proteoglycan/glycosaminoglycan alterations in JIA patients, which are stimulated by MMP-3 and reactive oxygen species (ROS), indicate rather systemic disturbance of extracellular matrix metabolism, and not merely local changes which occur in articular structures. Given the destructive potential of ROS and MMPs and their hyperexpression in JIA, inhibition of these compounds should bring a substantial clinical benefit.

Abstract
OBJECTIVE To estimate the relative risk of incident cancer diagnosis among patients with juvenile idiopathic arthritis (JIA) compared to patients without JIA. METHODS A cohort of biologics-naive patients diagnosed with JIA between 1998 and 2007 and a matched cohort of comparators without JIA were assembled from the PharMetrics Patient-Centric Database. The primary outcome was any incident malignancy, excluding nonmelanoma skin cancer and carcinoma in situ. Claims profiles of patients with any cancer-related diagnosis codes were reviewed to determine outcomes. Incidence rates and 95% confidence intervals (95% CIs) of cancer were calculated and compared between cohorts using Cox proportional hazards regression. Standardized incidence ratios (SIRs) for each cohort compared to the general population were calculated using reference rates from the US Surveillance, Epidemiology, and End-Results (SEER) program. RESULTS The JIA and non-JIA cohorts included 3,605 and 37,689 patients, respectively, with a mean age of 11 years. The incidence rates of cancer were 67.0 (95% CI 1.3-132.5) cases/100,000 person-years (PY) for JIA and 23.2 (95% CI 12.2-34.2) cases/100,000 PY for non-JIA. The risk of cancer associated with biologics-naive JIA was elevated (hazard ratio 2.8, 95% CI 0.9-8.3). The JIA cohort had a significantly elevated SIR of 4.0 (95% CI 2.6-6.0); the non-JIA cohort SIR was not significantly above SEER rates (SIR 1.4, 95% CI 0.6-2.6). CONCLUSION We found a nearly 3-fold increased risk of cancer in biologics-naive JIA patients, which approached significance despite the small number of outcomes. This finding suggests an elevated underlying risk of cancer in this disease population.

Abstract
PURPOSE OF REVIEW In this review we report an update on the current knowledge on growth disorders in children with chronic inflammatory diseases, mainly inflammatory bowel disease and juvenile idiopathic arthritis, with a particular focus on the role of inflammatory cytokines as mediators of growth impairment. RECENT FINDINGS Growth disorders are common among patients with inflammatory diseases. Several factors can contribute to growth failure: poor nutrition, immobilization, drugs, disease activity, duration and severity. There is extensive evidence suggesting that inflammatory cytokines are key players in mediating growth failure. Recent studies have confirmed a direct association between levels of inflammatory cytokines, such as tumour necrosis factor-α and interleukin-6, and reduced growth velocity, as well as impaired body composition. Recent studies have also highlighted the beneficial effect of new drugs, such biologics, not only in controlling disease activity, but also in improving growth. SUMMARY Growth retardation remains a major problem in patients with chronic inflammatory diseases, and proinflammatory cytokines are key players in this context. New drugs, specifically targeting inflammatory cytokines appear to be promising for their effect on growth. Further studies are required to better characterize the cytokine profile in children with inflammatory disease and help in developing effective treatment strategies.
