Abstract
OBJECTIVES The main goal of this study was to characterise the frequency and phenotype of B, T follicular helper (Tfh) and T follicular regulatory (Tfr) cells in peripheral blood and the cytokine environment present in circulation in children with extended oligoarticular juvenile idiopathic arthritis (extended oligo JIA) and polyarticular JIA (poly JIA) when compared with healthy controls, children with persistent oligoarticular JIA (persistent oligo JIA) and adult JIA patients. METHODS Blood samples were collected from 105 JIA patients (children and adults) and 50 age-matched healthy individuals. The frequency and phenotype of B, Tfh and Tfr cells were evaluated by flow cytometry. Serum levels of APRIL, BAFF, IL-1β, IL-2, IL-4, IL-6, IL-10, IL-17A, IL-21, IL-22, IFN-γ, PD-1, PD-L1, sCD40L, CXCL13 and TNF were measured by multiplex bead-based immunoassay and/or ELISA in all groups included. RESULTS The frequency of B, Tfh and Tfr cells was similar between JIA patients and controls. Children with extended oligo JIA and poly JIA, but not persistent oligo JIA, had significantly lower frequencies of plasmablasts, regulatory T cells and higher levels of Th17-like Tfh cells in circulation when compared with controls. Furthermore, APRIL, BAFF, IL-6 and IL-17A serum levels were significantly higher in paediatric extended oligo JIA and poly JIA patients when compared with controls. These immunological alterations were not found in adult JIA patients in comparison to controls. CONCLUSIONS Our results suggest a potential role and/or activation profile of B and Th17-like Tfh cells in the pathogenesis of extended oligo JIA and poly JIA, but not persistent oligo JIA.

Moura RA, Fonseca JE. B Cells on the Stage of Inflammation in Juvenile Idiopathic Arthritis: Leading or Supporting Actors in Disease Pathogenesis? Front Med (Lausanne) 2022; 9:851532. [PMID: 35449805 PMCID: PMC9017649 DOI: 10.3389/fmed.2022.851532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 02/09/2022] [Indexed: 11/13/2022] Open
Abstract
Juvenile idiopathic arthritis (JIA) is a term that collectively refers to a group of chronic childhood arthritides, which together constitute the most common rheumatic condition in children. The International League of Associations for Rheumatology (ILAR) criteria define seven categories of JIA: oligoarticular, polyarticular rheumatoid factor (RF) negative (RF-), polyarticular RF positive (RF+), systemic, enthesitis-related arthritis, psoriatic arthritis, and undifferentiated arthritis. The ILAR classification includes persistent and extended oligoarthritis as subcategories of oligoarticular JIA, but not as distinct categories. JIA is characterized by a chronic inflammatory process affecting the synovia that begins before the age of 16 and persists at least 6 weeks. If not treated, JIA can cause significant disability and loss of quality of life. Treatment of JIA is adjusted according to the severity of the disease as combinations of non-steroidal anti-inflammatory drugs (NSAIDs), synthetic and/ or biological disease modifying anti-rheumatic drugs (DMARDs). Although the disease etiology is unknown, disturbances in innate and adaptive immune responses have been implicated in JIA development. B cells may have important roles in JIA pathogenesis through autoantibody production, antigen presentation, cytokine release and/ or T cell activation. The study of B cells has not been extensively explored in JIA, but evidence from the literature suggests that B cells might have indeed a relevant role in JIA pathophysiology. The detection of autoantibodies such as antinuclear antibodies (ANA), RF and anti-citrullinated protein antibodies (ACPA) in JIA patients supports a breakdown in B cell tolerance. Furthermore, alterations in B cell subpopulations have been documented in peripheral blood and synovial fluid from JIA patients. In fact, altered B cell homeostasis, B cell differentiation and B cell hyperactivity have been described in JIA. Of note, B cell depletion therapy with rituximab has been shown to be an effective and well-tolerated treatment in children with JIA, which further supports B cell intervention in disease development.

Summarizing current refractory disease definitions in rheumatoid arthritis and polyarticular juvenile idiopathic arthritis: systematic review. Rheumatology (Oxford) 2021; 60:3540-3552. [PMID: 33710321 PMCID: PMC8328502 DOI: 10.1093/rheumatology/keab237] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 01/27/2021] [Accepted: 02/23/2021] [Indexed: 12/13/2022] Open
Abstract
OBJECTIVES To identify how refractory disease (or relevant terminology variations) in RA and polyarticular JIA (polyJIA) is defined and establish the key components of such definitions. METHODS Searches were undertaken of English-language articles within six medical databases, including manual searching, from January 1998 to March 2020 (PROSPERO: CRD42019127142). Articles were included if they incorporated a definition of refractory disease, or non-response, in RA/polyJIA, with clear components to the description. Qualitative content analysis was undertaken to describe refractory disease in RA/polyJIA and classify each component within each definition. RESULTS Of 6251 studies screened, 646 met the inclusion criteria; 581 of these applied non-response criteria while 65 provided refractory disease definitions/descriptions. From the non-response studies, 39 different components included various disease activity measures, emphasizing persistent disease activity and symptoms, despite treatment with one or more biologic DMARD (bDMARD). From papers with clear definitions for refractory disease, 41 components were identified and categorized into three key themes: resistance to multiple drugs with different mechanisms of action, typically two or more bDMARDs; persistence of symptoms and disease activity; and other contributing factors. The most common term used was 'refractory' (80%), while only 16.9% reported explicitly how their definition was generated (e.g. clinical experience or statistical methods). CONCLUSION Refractory disease is defined as resistance to multiple drugs with different mechanisms of action by persistence of physical symptoms and high disease activity, including contributing factors. A clear unifying definition needs implementing, as the plethora of different definitions makes study comparisons and appropriate identification of patients difficult.

Abstract
OBJECTIVE To investigate the incidence and risk factors for hypogammaglobulinemia and infectious complications associated with rituximab treatment in childhood-onset rheumatic diseases. METHODS We performed a single-center retrospective study of patients (n = 85) treated at Boston Children's Hospital (BCH) from 2009 to 2019. Study subjects included patients (ages 6 to 24) who received rituximab for the treatment of a childhood-onset rheumatic disease. RESULTS New-onset hypogammaglobulinemia developed in 23 (27.1%) patients within 18 months of rituximab induction treatment. 22 patients (25.9%) developed at least one infectious complication in the 18 months following the first rituximab infusion; of these, 11 (50%) had serious infections requiring inpatient treatment. After adjusting for potential confounders, exposure to pulse corticosteroid therapy in the month prior to rituximab use was a significant predictor of both new-onset hypogammaglobulinemia (OR 3.94; 95% CI 1.07-16.0; p = 0.044) and infectious complications (OR 15.3; 95% CI 3.04-126.8; p = 0.003). Post-rituximab hypogammaglobulinemia was the strongest predictor of serious infectious complications (OR 7.89; 95% CI 1.41-65.6; p = 0.028). Younger age at rituximab use was also a significant predictor of new-onset hypogammaglobulinemia (OR 0.83; 95% CI 0.70-0.97; p = 0.021). Compared with other rheumatic diseases, patients with vasculitis had a higher likelihood of developing infectious complications, including serious infections. CONCLUSION Although rituximab was well tolerated in terms of infectious complications in the majority of patients with childhood-onset rheumatic diseases, a substantial proportion developed new-onset hypogammaglobulinemia and infectious complications following treatment. Our study highlights a role for heightened vigilance of rituximab-associated hypogammaglobulinemia and infections in pediatric patients with rheumatic conditions.

Abstract
Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease affecting the joints and other organs that occurs in 1 in 1,000 children in the United States. Given the various categories of JIA, interpretation of the literature can be difficult. In this review, new developments in understanding non-systemic JIA and its treatment will be covered. Recent advances in the journey toward personalized treatment in JIA will be highlighted, including a review of currently available biologic modifiers. Uveitis and the temporomandibular joint will be discussed as particularly challenging treatment issues. Recent guideline updates and literature-guided treatment decisions will be reviewed.

Abstract
Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease and an exclusion diagnosis that includes all forms of arthritis that persists for more than 6 weeks under the age of 16. Although there is not yet a cure for JIA, and recent advances in the therapeutic field have created a more hopeful present and future for the patients. In the past, therapies for JIA have depended on non-steroidal medication, conventional synthetic disease-modifying antirheumatic drugs and corticosteroids. However, over the last decades, the advent of biologic therapies in JIA contributed to the preservation of functional activity, control of pain, avoidance of joint damage, and extra-articular manifestations. Furthermore, over the last years, international institutions, such as the American College of Rheumatology, have released recommendations and guidelines for rheumatologists for optimal JIA management. All the above have revolutionized the treatment of JIA with promising outcomes. To this end, the relevant literature is reviewed and discussed appropriately.

Abstract
UNLABELLED In the past years, pediatric rheumatology has seen a revolution in the treatments for rheumatic diseases, particularly juvenile idiopathic arthritis. Even if nonsteroidal anti-inflammatory drugs (NSAID), intra-articular corticosteroids (IAC) injections, and methotrexate remain the mainstay of the treatment for JIA patients, in aggressive disease, these treatments may be not sufficient to reach disease remission and to prevent long-term disability. Comprehension of immunological mechanisms involved in the pathogenesis of the diseases allowed to conceive new drugs targeting specific steps of the immune response. Several cytokines, like TNF alpha and IL-1, represent a very interesting target for biologic therapies. Due to the efficacy of these therapies, nowadays, "disease remission" in pediatric rheumatology is more and more frequent, especially in juvenile idiopathic arthritis patients, and the long-term outcomes have been significantly improved. Crucial to these advancements have been multicenter controlled clinical trials and long-term safety monitoring. CONCLUSIONS Research in pediatric rheumatology has resulted in dramatic advances in diseases management. Biologic treatments have improved physical and functional outcomes and quality of life of patients with rheumatic disease. What is Known: • NSAID, intra-articular injection of corticoids, and methotrexate are the mainstay in treatment of JIA. • In aggressive JIA, these treatments may be not sufficient to reach disease remission and to prevent long term disability. What is New: • In recent years, management of JIA has significantly improved with the development of biologic therapies that allowed children with arthritis to reach a normal growth and to achieve a good long-term functional outcome.

Abstract
In a proportion of patients, chikungunya arthritis (CA) might run into a chronic persistent phase. The treatment for this phase is not very clear. In this randomized parallel group open label study of 24 weeks duration, we evaluated the efficacy of DMARD combination in persistent CA. Consecutive 139 patients with persistent CA (persistent arthritis for >1 year after the chikungunya fever either in 2008 or 2009 fulfilling epidemiological criteria for CA) were screened. Of these patients who were already taking hydroxychloroquine (HCQ) and had active arthritis were randomized to receive either fixed-dose combination therapy (methotrexate 15 mg/day, sulfasalazine 1 g/day, and HCQ 400 mg/day) or continue with HCQ 400 mg/day (dose optimized) monotherapy. Both groups received oral prednisolone up to 6 weeks. Assessments at every 4 weeks were carried out for primary efficacy (disease activity score; DAS ESR 28) and secondary efficacies, HAQ-Indian version and pain VAS100mm. Seventy-two patients were randomized (37 combination therapy, 35 monotherapy). Both groups were well matched in all respects. At 24 weeks, the combination therapy group showed significant improvement in both disease activity (mean ± SD DAS28; 3.39 ± 0.87 vs. 4.74 ± 0.65, p < 0.0001) and disability (mean ± SD HAQ; 1.4 ± 0.31 vs. 1.88 ± 0.47, p < 0.0001). At the study end, pain VAS was significantly less in the combination therapy group (46 ± 6.13 vs. 60.8 ± 11.6, p < 0.0001). Three patients withdrew from the combination group (inefficacy; 2, adverse event; 1) and seven from monotherapy (inefficacy; 7). This study provide evidence that for chronic persistent CA combination DMARD therapy with methotrexate, sulfasalazine and HCQ is superior to monotherapy with HCQ.

Abstract
Inflammation is all a pervasive phenomenon, which is elicited by the body in response to obnoxious stimuli as a protective measure. However, sustained inflammation leads to several diseases including cancer. Therefore it is necessary to neutralize inflammation. Sonapatha (Oroxylum indicum), a medicinal plant, is traditionally used as a medicine in Ayurveda and other folk systems of medicine. It is commonly used to treat inflammatory diseases including rheumatoid arthritis and asthma. Despite this fact its anti-inflammatory and analgesic effects are not evaluated scientifically. Therefore, the anti-inflammatory and analgesic activities of Sonapatha (Oroxylum indicum) were studied in Swiss albino mice by different methods. The hot plate, acetic acid, and tail immersion tests were used to evaluate the analgesic activity whereas xylene-induced ear edema and formalin induced paw edema tests were used to study the anti-inflammatory activity of Sonapatha. The administration of mice with 250 and 300 mg/kg b.wt. of O. indicum reduced pain and inflammation indicating that Sonapatha possesses analgesic and anti-inflammatory activities. The maximum analgesic and anti-inflammatory activities were observed in mice receiving 300 mg/kg b.wt. of O. indicum ethanol extract. Our study indicates that O. indicum possesses both anti-inflammatory and analgesic activities and it may be useful as an anti-inflammatory agent in the inflammation related disorders.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood. Without an effective therapy, patients may progress quickly to functional disability. Recently, depletion of B cells emerged as a new approach for the treatment of autoimmune diseases, including JIA. We describe six cases of JIA patients followed at a referral center for Rheumatology and Pediatric Rheumatology, submitted to treatment with rituximab (RTX) after refractoriness to three anti-TNF agents. Patients received RTX cycles with two infusions every six months. Response to treatment was assessed by DAS28, HAQ/CHAQ, and an overall assessment by the doctor and the patient. Of our six patients, four were girls (mean age at onset of disease: 6.1 years; mean disease evolution time: 15.1 years; mean age upon receiving RTX: 21.6 years). Four patients belonged to polyarticular subtype (1 rheumatoid factor [RF]-negative, 3 FR-positive), a patient with systemic JIA subtype with a polyarticular course and arthritis related to enthesitis. Of our six patients, five responded to treatment; and during the course of 12 months, the clinical response was maintained, although not sustained. However, discontinuation by infusion reactions caused the withdrawal of RTX in two patients. The use of RTX in JIA is restricted to cases refractory to other biological agents and, even considering that this study was held in a small number of advanced patients, RTX proved to be an effective therapeutic option.

Abstract
Juvenile idiopathic arthritis (JIA) is defined as arthritis of unknown cause that starts before 16 years of age and lasts at least 6 weeks. It is the most common chronic inflammatory disease in childhood and often persists through adulthood and can lead to severe disability. Biologics are an important therapeutic option for treating patients with JIA. The efficiency of rituximab has not been proven for this indication. Its use has rarely been reported in the literature. We report two new cases of severe and refractory polyarticular JIA with positive rheumatoid factor affecting two African females aged 17 and 18 years successfully treated with rituximab. According to our experience, the use of rituximab in the treatment of JIA, especially in severe polyarticular forms with positive rheumatoid factor, might be a good alternative. Larger therapeutic trials should be conducted in this direction in order to prove the effectiveness of this biotherapy for this indication.

Abstract
A generation ago, children with arthritis faced a lifetime of pain and disability. Today, there are a multitude of treatment options, including a variety of biologics targeting key cytokines and other inflammatory mediators. While non-steroidal anti-inflammatory drugs and corticosteroids were once the mainstay of therapy, they are now largely used as bridge or adjunctive therapies. Among the conventional disease-modifying anti-rheumatic drugs, methotrexate remains first-line therapy for most children with juvenile idiopathic arthritis (JIA) due to its long track record of safety and effectiveness in the management of peripheral arthritis. Sulfasalazine and leflunomide may also have a secondary role. The tumor necrosis factor inhibitors (TNFi) have shown tremendous benefit in children with polyarticular JIA and likely in enthesitis-related arthritis and psoriatic JIA as well. There may be additional benefit in combining TNFi with methotrexate. Abatacept and tocilizumab also appear to benefit polyarticular JIA; the role of rituximab remains unclear. For the treatment of systemic JIA, while the TNFi are of less benefit, blockade of interleukin-1 or interleukin-6 is highly effective. Additionally, interleukin-1 blockade appears to be effective treatment of macrophage activation syndrome, one of the most dangerous complications of JIA; specifically, anakinra in combination with cyclosporine and corticosteroids may obviate the need for cytotoxic approaches. In contrast, methotrexate along with the TNFi and abatacept are effective agents for the management of uveitis, another complication of JIA. Overall, the biologics have demonstrated an impressive safety record in children with JIA, although children do need to be monitored for rare but potentially dangerous adverse events, such as tuberculosis and other infections; paradoxical development of additional autoimmune diseases; and possibly an increased risk of malignancy. Finally, there may be a window of opportunity during which children with JIA will demonstrate most optimal responses to aggressive therapy, underscoring the need for rapid diagnosis and initiation of treatment.

Abstract
OBJECTIVE To assess the level of B-cell activating factor belonging to the tumor necrosis factor family (BAFF) also known as B-lymphocyte stimulator (BLyS) and A proliferation-inducing ligand (APRIL) in the serum of Juvenile idiopathic arthritis (JIA) patients and to detect their relation to the clinical manifestations and disease activity in the different subtypes of the disease. METHODS Seventy-four consecutively recruited JIA patients were clinically examined, the Juvenile arthritis disease activity score in 27 joints (JADAS-27) calculated and Childhood Health Assessment Questionnaire (CHAQ) used to measure the functional status. Thirty-four healthy matched children served as controls. Routine laboratory examinations were recorded and serum BAFF and April were determined. RESULTS The JIA patients were 20 systemic-onset, 31 oligoarticular and 23 polyarticular. Serum BAFF and APRIL were elevated in JIA patients being higher in systemic onset and both significantly correlated. APRIL significantly correlated with both JADAS-27 and CHAQ scores while BAFF correlated only with JADAS-27. The APRIL serum levels were significantly associated with the presence of RF and ANA. The BAFF serum levels were significantly higher in oligoarticular onset JIA patients with uveitis compared to those without. CONCLUSION Our results suggest increased BAFF and APRIL serum levels in JIA patients denoting their possible role in the disease and calling for additional research to elucidate the intrinsic mechanisms explaining APRIL and BAFF over expression.

Abstract
BACKGROUND Since initial approval for the treatment of rheumatoid arthritis (RA), rituximab has been evaluated in clinical trials involving various populations with RA. Information has also been gathered from registries. This report therefore updates the 2007 consensus document on the use of rituximab in the treatment of RA. METHODS Preparation of this new document involved many international experts experienced in the treatment of RA. Following a meeting to agree upon the core agenda, a systematic literature review was undertaken to identify all relevant data. Data were then interrogated by a drafting committee, with subsequent review and discussion by a wider expert committee leading to the formulation of an updated consensus statement. These committees also included patients with RA. RESULTS The new statement covers wide-ranging issues including the use of rituximab in earlier RA and impact on structural progression, and aspects particularly pertinent to rituximab such as co-medication, optimal dosage regimens, repeat treatment cycles and how to manage non-response. Biological therapy following rituximab usage is also addressed, and safety concerns including appropriate screening for hepatitis, immunoglobulin levels and infection risk. This consensus statement will support clinicians and inform patients when using B-cell depletion in the management of RA, providing up-to-date information and highlighting areas for further research. CONCLUSION New therapeutic strategies and treatment options for RA, a chronic destructive and disabling disease, have expanded over recent years. These have been summarised in general strategic suggestions and specific management recommendations, emphasising the importance of expedient disease-modifying antirheumatic drug implementation and tight disease control. This consensus statement is in line with these fundamental principles of management.

Abstract
Juvenile Idiopathic Arthritis (JIA) is the most common cause of chronic arthritis in childhood and adolescents and encompasses a heterogeneous group of different diseases. Due to the promising results of B-cell depleting therapies in rheumatoid arthritis the role of B-cells in autoimmune diseases has to be discussed in a new context. Additionally, experiments in mouse models have shed new light on the antibody-independent role of B-cells in the development of autoimmune diseases. In this review we will discuss the importance of B-cells in the pathogenesis of JIA appraising the question for an immunological basis of B-cell targeted therapy in JIA.

Abstract
We describe a patient with systemic onset juvenile idiopathic arthritis refractory to disease-modifying antirheumatic drugs, intravenous gamma globulin, and TNF inhibitors (etanercept and infliximab), in whom treatment with rituximab resulted in remission of systemic symptoms (rash and fever), a fall in erythrocyte sedimentation rate, C-reactive protein, and ferritin serum levels, with recovery in disability index and improvement of arthritis. A total of 4 cycles of rituximab were given over 18 months because of relapses. Since her last course, she remains stable and asymptomatic. To our knowledge, this is the first case reported on a long-lasting beneficial effect of rituximab in a patient with soJIA.

Abstract
Introduction In chronic inflammatory disorders, B cells can contribute to tissue damage by autoantibody production and antigen presentation to T cells. Here, we have characterized synovial fluid and tissue B-cell subsets in patients with oligoarticular juvenile idiopathic arthritis (JIA), an issue not addressed before in detail. Methods B cells from synovial fluid (SF) and peripheral blood (PB) of 25 JIA patients, as well as from PB of 20 controls of comparable age, were characterized by multicolor flow cytometry. Immunoglobulin-secreting cells were detected by ELISPOT. Immunohistochemical analyses of synovial tissue from three JIA patients were performed. Results JIA SF B cells were enriched in CD27+ and CD27- switch memory B cells, but not in CD27+ IgM memory B cells, compared with patient and control PB. Plasma blasts were more abundant in SF and secreted higher amounts of IgG. Lymphoid aggregates not organized in follicle-like structures were detected in synovial tissue sections and were surrounded by CD138+ plasma cells. Finally, transitional B cells were significantly increased in JIA PB versus SF or control PB. CCR5, CCR8, CXCR2, and CXCR3 were upregulated, whereas CCR6, CCR7, and CXCR5 were downregulated on SF CD27+ and CD27- switch memory B cells compared with their circulating counterparts. SF CD27+ and CD27- switch memory B cells expressed at high levels the costimulatory molecule CD86 and the activation marker CD69. Conclusions This study demonstrates for the first time an expansion of activated switch memory B cells and of IgG-secreting plasma blasts in the SF from oligoarticular JIA patients. Memory B cells belonged to either the CD27+or the CD27- subsets and expressed CD86, suggesting their involvement in antigen presentation to T cells. Patterns of chemokines-receptor expression on CD27+ and CD27- switch memory B cells delineated potential mechanisms for their recruitment to the inflamed joints.

Abstract
Pediatric non-infectious uveitis remains a rare but potentially sight-threatening group of diseases. However, early screening and treatment can improve outcomes. No single agent has proven to be efficacious in all cases. A wide variety of long-term immunomodulatory treatments are available; these agents differ in both their potency and side effect profiles. Corticosteroids remain an extremely valuable form of treatment in the short-term management of uveitis. Other major groups of immunomodulatory treatments include the calcineurin inhibitors and antimetabolites such as methotrexate, which is frequently used as the first-line agent. The biologics, including anti-tumor necrosis factor agents and interferons, are newer and potentially very useful therapies although side effects limit their use. Successful outcomes may be achieved with appropriate immunosuppressant therapy given early in the disease, although clinical trials are required to define the true efficacy of this strategy.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common autoimmune-autoinflammatory disease in childhood and affects approximately 1 in 1,000 children. Despite advances in diagnosis and treatment options, JIA remains a chronic condition for most affected children. Recent evidence suggests that disease control at onset may determine the tempo of subsequent disease course and long-term outcomes, and raises the concept of a therapeutic window of opportunity in patients with JIA. This underscores the importance of early aggressive treatment in patients with JIA. With the advent of novel biologic therapeutics, the repertoire of agents available for treatment of children with JIA has greatly increased. The present article will summarize recent developments in the medical treatment of children with JIA and will offer insights into emerging therapies.

Abstract
Biologics have advanced the therapy of adult and pediatric arthritis. They have been linked to rare serious adverse outcomes, but the actual risk of these events is controversial in adults, and largely unknown in pediatrics. Because of the paucity of safety and efficacy data in children, pediatric rheumatologists often rely on the adult literature. Herein, we reviewed the adult and pediatric literature on five classes of medicines: Tumor necrosis factor (TNF) inhibitors, anakinra, rituximab, abatacept, and tocilizumab. For efficacy, we reviewed randomized controlled studies in adults, but did include lesser qualities of evidence for pediatrics. For safety, we utilized prospective and retrospective studies, rarely including reports from other inflammatory conditions. The review included studies on rheumatoid arthritis and spondyloarthritis, as well as juvenile idiopathic arthritis. Overall, we found that the TNF inhibitors have generally been found safe and effective in adult and pediatric use, although risks of infections and other adverse events are discussed. Anakinra, rituximab, abatacept, and tocilizumab have also shown positive results in adult trials, but there is minimal pediatric data published with the exception of small studies involving the subgroup of children with systemic onset juvenile idiopathic arthritis, in whom anakinra and tocilizumab may be effective therapies.
