A randomized, double-blind, placebo-controlled 12-week trial of infliximab in patients with juvenile-onset spondyloarthritis. Arthritis Res Ther 2022; 24:187. [PMID: 35941676 PMCID: PMC9358905 DOI: 10.1186/s13075-022-02877-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Accepted: 07/24/2022] [Indexed: 11/19/2022] Open
Abstract
Objective To assess the efficacy and safety of infliximab versus placebo in the treatment of patients with juvenile-onset spondyloarthritis (JoSpA). Methods Phase III, randomized, double-blind, placebo-controlled trial of 12 weeks that included patients ≤ 18 years old with JoSpA not responding to nonsteroidal anti-inflammatory drugs, sulfasalazine, or methotrexate. Patients were randomly assigned 1:1 to the infusion of infliximab 5mg/kg or placebo; completers entered then an open-label extension (OLE) period of 42 weeks. The primary endpoint was the number of active joints. Secondary outcomes included the assessment of disease activity, tender entheses, spinal mobility, serum C-reactive protein (CRP), the Bath Ankylosing Spondylitis Disease Activity and Functional Index, and the Childhood Health Assessment Questionnaire (CHAQ). Results We randomized 12 patients to infliximab and 14 to placebo. No significant differences were found between groups at baseline. At week 12, the mean number of active joints was 1.4 (SD 2.4) in the infliximab group and 4.1 (SD 3.0) in the placebo group (p = 0.0002). A repeated-measures mixed model analysis that included all endpoints in the study demonstrated sustained favourable outcomes of infliximab for active joints, tender joints, swollen joints, and tender enthesis counts, as well as for CHAQ and CRP (p < 0.01). Adverse events were more frequent in the infliximab group, including infections and infusion reactions, but none of them was serious. Conclusion Infliximab is efficacious for patients with JoSpA with an inadequate response to conventional treatment. No serious adverse events with the use of infliximab were observed.

Abstract
Some studies have suggested children with juvenile onset spondyloarthritis (JoSpA) have a relatively poor outcome compared to other juvenile idiopathic arthritis (JIA) categories, in regards to functional status and failure to attain remission. Thus, in the interest of earlier recognition and risk stratification, awareness of the unique characteristics of this group is critical. Herein, we review the clinical burden of disease, prognostic indicators and outcomes in JoSpA. Of note, although children exhibit less axial disease at onset compared to adults with spondyloarthritis (SpA), 34–62% have magnetic resonance imaging (MRI) evidence for active inflammation in the absence of reported back pain. Furthermore, some studies have reported that more than half of children with “enthesitis related arthritis” (ERA) develop axial disease within 5 years of diagnosis. Axial disease, and more specifically sacroiliitis, portends continued active disease. The advent of TNF inhibitors has promised to be a “game changer,” given their relatively high efficacy for enthesitis and axial disease. However, the real world experience in various cohorts since the introduction of more widespread TNF inhibitor usage, in which greater than a third still have persistently active disease, suggests there is still work to be done in developing new therapies and improving the outlook for JoSpA.

Abstract
In our paper, we discuss how the early phases of ankylosing spondylitis (AS) are linked to peri-firbocartilagenous osteitis in the sacroiliac joint and entheseal bone related anchoring sites. This skeletal proclivity is linked to an abnormal immunological response to skeletal biomechanical stress and associated microdamage. A key event in the early stages of AS appears to be the association with subclinical Crohn's-like colitis with this gut inflammation being pivotal to the osteitis reaction. Whether this osteitis is consequent to non-specific intestinal innate immune activation or adaptive immune responses against specific microbiotal or self-antigens is unknown. Recurrent iritis is an HLA-B27 associated feature that may predate AS and pursues a course independent of joint involvement, and points toward the pivotal role of organ specific immunology over generalized systemic immune responses in disease expression. Human genetics and animal model studies strongly incriminate the IL23/17 axis and TNF-α in disease pathogenesis. Preliminary work shows a strong convergence of innate immune cells including type 3 innate lymphoid-cells (ILC3) and γδ T-cells in skin, gut, entheseal, and eye inflammation. Despite the HLA-B27 association, the role of adaptive immunity, especially CD8+ T-cells mediated responses remains unproven and alternative theories have been proposed. The emerging non-dependence of axial inflammation on IL-23 but dependence on IL-17A is an unexpected new twist that awaits full explanation. In this mini-review, we discuss the key events in the early stages of human AS from clinical and basic science aspects, which could be crucial for attempted disease prevention studies in at risk subjects.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common disease in pediatric rheumatism. There is no specific symptom or examination finding for JIA, and the diagnosis is made by exclusion and differentiation. Because non-pediatric rheumatologists are sometimes involved in medical care, 'proposal for JIA guidance on diagnosis and treatment for primary care pediatricians and non-pediatric rheumatologists' was first published in 2007. In these 10 years, a number of new findings on pathophysiology and treatment of JIA have been published; therefore, we propose this guidance of 2018th edition aiming at updating and standardization of JIA medical care in Japan. This edition included the management of uveitis, macrophage activation syndrome, infectious diseases before and during treatment. Moreover, details of biologics are also described. Although this guidance is tailored to adaptation of examinations and drugs, we do not purpose to limit the physicians' discretion in clinical practice. This guidance should be viewed as recommendations and be individualized according to the condition of the patient. We hope that medical care for JIA will advance and more patients will get benefit based on this guidance. Then, further revisions are needed due to changes in future conditions.

Abstract
The enthesitis-related arthritis (ERA) category of juvenile idiopathic arthritis (JIA) is the most common category in India. HLA B27 has a high prevalence in ERA, and ILAR classification includes it in exclusion criteria for other categories, but due to its cost, it is not routinely done. We undertook this study to assess the prevalence of HLA B27 in ERA and other groups of juvenile arthritis in India. Consecutive patients of JIA ERA and select patients from other categories were recruited from a single tertiary care hospital over a span of 3 years. HLA B27 was tested using PCR. Five hundred and eleven children were studied: 312 had ERA, and 199 had other categories (29 oligoarthritis, 107 polyarthritis, 44 systemic onset JIA, 9 psoriatic arthritis and 10 undifferentiated). The prevalence of HLA B27 was highest in the ERA group (87 %) and correlated with the presence of sacroiliitis. Prevalence was 10.3 % in oligoarthritis, 16 % in polyarticular rheumatoid factor (RF)-positive arthritis, 26 % in RF-negative polyarticular arthritis, 66 % in psoriatic arthritis and 40 % in the unclassified and 0 % in systemic onset category. Twenty-seven children had a change in category of JIA as per ILAR owing to HLA B27 testing positive, most commonly in the RF-negative polyarthritis group. Only six of these had clinical features suggestive of Spondyloarthropathy. There is high prevalence of HLA B27 in ERA. Though HLA B27 testing helps in correct classification, a minority of these patients have features suggestive of spondyloarthropathy like back pain, enthesitis or sacroiliitis.

Diagnositic value of pelvic enthesitis on MRI of the sacroiliac joints in enthesitis related arthritis. Pediatr Rheumatol Online J 2015; 13:46.

Abstract
BACKGROUND To determine the prevalence and diagnostic value of pelvic enthesitis on MRI of the sacroiliac (SI) joints in enthesitis related arthritis (ERA). METHODS We retrospectively studied 143 patients aged 6-18 years old who underwent MRI of the SI joints for clinically suspected sacroiliitis between 2006-2014. Patients were diagnosed with ERA according to the International League of Associations for Rheumatology (ILAR) criteria. All MRI studies were reassessed for the presence of pelvic enthesitis, which was correlated to the presence of sacroiliitis on MRI and to the final clinical diagnosis. The added value for detection of pelvic enthesitis and fulfilment of criteria for the diagnosis of ERA was studied. RESULTS Pelvic enthesitis was seen in 23 of 143 (16 %) patients. The most commonly affected sites were the entheses around the hip (35 % of affected entheses) and the retroarticular interosseous ligaments (32 % of affected entheses). MRI showed pelvic enthesitis in 21 % of patients with ERA and in 13 % of patients without ERA. Pelvic enthesitis was seen on MRI in 7/51 (14 %) patients with clinically evident enthesitis, and 16/92 (17 %) patients without clinically evident enthesitis. In 7 of 11 ERA-negative patients without clinical enthesitis but with pelvic enthesitis on MRI, the ILAR criteria could have been fulfilled, if pelvic enthesitis on MRI was included in the criteria. There is a high correlation between pelvic enthesitis and sacroiliitis, with sacroiliitis present in 17/23 (74 %) patients with pelvic enthesitis. CONCLUSIONS Pelvic enthesitis may be present in children with or without clinically evident peripheral enthesitis. There is a high correlation between pelvic enthesitis and sacroiliitis on MRI of the sacroiliac joints in children. As pelvic enthesitis indicates active inflammation, it may play a role in assessment of the inflammatory status. Therefore, it should be carefully sought and noted by radiologists examining MRI of the sacroiliac joints in children.

Abstract
Ankylosing spondylitis is a chronic inflammatory rheumatic disease, which is characterized by inflammation of the spine and the sacroiliac joints. To date, the disease etiology remains unclear. In the present study, the correlation of T lymphocyte subset changes with the progression of ankylosing spondylitis was investigated. A total of 55 patients with ankylosing spondylitis (22 severe and 23 mild cases) and 20 healthy individuals were selected. Firstly, the punctured cells in the lesions and the serum were collected, and the lymphocytes and the peripheral blood mononuclear cells were prepared. Secondly, quantitative PCR, ELISA and flow cytometry analyses were carried out to detect the levels of a series of immunoglobulins, complements, helper T cells, cytotoxic T cells, regulatory cells and cytokines. The expression levels of α-globulin, γ-globulin, immunoglobulin (Ig)G, IgA, IgM, serum complement C3, and complement C4 were found to be significantly increased in ankylosing spondylitis patients. In addition, the percentage of Th1 and Th17 cells was found to be significantly higher in the ankylosing spondylitis groups (mild and severe) compared with the healthy individuals. As a result, the Th1/Th2 and Th17/Treg ratios were significantly higher in patients with ankylosing spondylitis. In addition, T lymphocyte subset ratio imbalances contributed to an increased expression of immune mediators, including interferon (IFN)-γ and interleukin (IL)-17A. The mRNA and protein expression levels of IFN-γ and IL-17A were found to be higher in the ankylosing spondylitis groups compared with the control group. The present study provided further evidence on the function and underlying mechanism of T lymphocyte subsets, which may be useful in the diagnosis and treatment of ankylosing spondylitis.

The assessment of the spondyloarthritis international society concept and criteria for the classification of axial spondyloarthritis and peripheral spondyloarthritis: A critical appraisal for the pediatric rheumatologist. Pediatr Rheumatol Online J 2012; 10:14.

Abstract
This review refers to the origin and current state of the assessment of the SpondyloArthritis International Society (ASAS) criteria for the classification of axial and peripheral spondyloarthritis (SpA) and the possible implications in the pediatric population. The ASAS criteria evolved from the idea that the earlier the recognition of patients with ankylosing spondylitis, the better the efficacy of tumor necrosis factor blockers. Strategies included the development of new concepts, definitions, and techniques for the study of clinical signs and symptoms. Of relevance, the new definition of inflammatory back pain (IBP) and the introduction of sacroiliitis by magnetic resonance imaging represented the most important advance in the early identification of AS in the "pre-radiographic stage" of the disease. AS is considered in this paper as a disease continuum with symptoms depending on age at onset. The application of those specific strategies in children and adolescents with SpA seems limited because the most important manifestation in the early stage of disease is not IBP, but peripheral arthritis and enthesitis. In this instance, the logical approach to juvenile onset SpA according to ASAS criteria should not be through the axial criteria but rather the peripheral set of criteria.

Abstract
Although musculoskeletal ultrasound (MSUS) has emerged as an indispensible tool among physicians involved in musculoskeletal medicine in the last two decades, only recently has it become more attractive to pediatric rheumatologists. Thereafter, the use of MSUS in pediatric rheumatology has started to increase. Yet, an ever-growing body of literature shows parity and even superiority of MSUS when compared to physical examination and other imaging modalities.MSUS is suitable for examination of children of all ages and it has certain advantages over other imaging modalities; as it is cheaper, mobile, instantly accessible bedside, easy to combine with clinical assessment (interactivity) and non-invasive. It does not require sedation, which facilitates repetitive examinations. Assessment of multiple locations is possible during the same session. Agitation is rarely a problem and small children can be seated in their parents' lap or they can even play while being examined.

Abstract
BACKGROUND The presence of enthesitis (insertional inflammation) in patients with juvenile idiopathic arthritis (JIA) is difficult to establish clinically and may influence classification and treatment of the disease. We used ultrasonography (US) and color Doppler (CD) imaging to detect enthesitis at the small and deep-seated proximal insertion of the gluteus medius fascia on the posterior iliac crest where clinical diagnosis is difficult. The findings in JIA patients were compared with those obtained in healthy controls and with the patients' MRI results. METHODS Seventy-six proximal gluteus medius insertions were studied clinically (tenderness to palpation of the posterior iliac crest) and by US and CD (echogenicity, thickness, hyperemia) in 38 patients with JIA and in 38 healthy controls, respectively (median age 13 years, range 7-18 years). In addition, an additional MRI examination of the sacroiliac joints and iliac crests was performed in all patients. RESULTS In patients with focal, palpable tenderness, US detected decreased echogenicity of the entheses in 53% of the iliac crests (bilateral in 37% and unilateral in 32%). US also revealed significantly thicker entheses in JIA patients compared to healthy controls (p < 0.003 left side, p < 0.001 right side). There was no significant difference in thickness between the left and right sides in individual subjects. Hyperemia was detected by CD in 37% (28/76) of the iliac crests and by contrast-enhanced MRI in 12% (6/50). CONCLUSIONS According to US, the gluteus medius insertion was thicker in JIA patients than in controls, and it was hypoechoic (enthesitis) in about half of the patients. These findings may represent chronic, inactive disease in some of the patients, because there was only limited Doppler flow and MRI contrast enhancement. The present study indicates that US can be useful as an adjunct to clinical examination for improved assessment of enthesitis in JIA. This may influence disease classification, ambition to treat, and choice of treatment regimen.

Abstract
OBJECTIVE Pediatric rheumatologists may have an opportunity to diagnose sacroiliitis in its early stages, prior to the development of irreversible radiographic changes. Early diagnosis frequently requires magnetic resonance imaging (MRI), the use of which is limited by expense and requirement for sedation. We set out to identify features of juvenile spondyloarthritis (SpA) associated with the highest risk of sacroiliitis, to identify patients who may be candidates for routine MRI-based screening. METHODS We reviewed the charts of 143 children seen at Texas Scottish Rite Hospital for Children diagnosed with SpA based on the International League of Associations for Rheumatology criteria for enthesitis-related arthritis or the Amor criteria for SpA. We performed logistic regression analysis to identify risk factors for sacroiliitis. RESULTS A group of 143 children were diagnosed with SpA. Consistent with the diagnosis of SpA, 16% had psoriasis, 43% had enthesitis, 9.8% had acute anterior uveitis, and 70% were HLA-B27+. Fifty-three children had sacroiliitis, of which 11 cases were identified by imaging studies in the absence of suggestive symptoms or physical examination findings. Logistic regression analysis revealed that hip arthritis was a positive predictor of sacroiliitis, while dactylitis was a negative predictor. CONCLUSION Children with SpA are at risk for sacroiliitis, which may be present in the absence of suggestive symptoms or physical examination findings. The major risk factor for sacroiliitis is hip arthritis, while dactylitis may be protective. Routine screening by MRI should be considered in patients at high risk of developing sacroiliitis.

Abstract
Spondyloarthritis (SpA) refers to a spectrum of immune-mediated inflammatory diseases with overlapping features, which differ from other types of inflammatory arthritis in genetic predisposition, pathogenesis and outcome. SpA frequently involves the axial skeleton, and can result in abnormal bone formation with eventual ankylosis of the spine, resulting in substantial disability. SpA often begins as an 'undifferentiated' disease, the presentation of which differs in children and adults; most notably, spinal involvement is uncommon, while hip arthritis and enthesitis are frequently seen in juvenile-onset disease. Currently, the classification of SpA in adults and children is approached differently. Using the International League of Associations for Rheumatology (ILAR) system for juvenile idiopathic arthritis, most childhood SpA is classified as enthesitis-related arthritis. However, in contrast to adult SpA classification, the presence of, or a family history of, psoriasis dictates a separate category of juvenile idiopathic arthritis. More importantly, the ILAR system does not specifically recognize the presence of axial disease in juvenile SpA. Resolution of these issues will improve communication and the transitioning of patients from pediatric to adult clinics, will facilitate research in genetics and pathogenesis, and will be particularly important in the evaluation of tumor necrosis factor inhibitors and other biologic agents for early, axial SpA.

Abstract
Spondyloarthritides (SpAs) are a cluster of chronic inflammatory rheumatic diseases that typically involve inflammation of axial and peripheral joint or tendon and ligament insertions, distinct radiographic changes and diverse extra-articular features. Conventional treatments relieve the signs and symptoms but do not prevent disease progression. TNFalpha inhibitors provide clinicians with the potential to treat the underlying pathology and to alter disease progression. By targeting the underlying inflammatory mechanisms, TNFalpha blockade can treat any extra-articular manifestations of SpA.

Abstract
Plantar fasciitis is a common painful syndrome that is usually treated by irradiation with a fraction dose (fd) of 1 Gy up to a total dose (TD) of 6 Gy according to clinical experience. By analysing our experiences with numerous former patients, we have attempted to find the relationship between dose and effect. To evaluate the effectiveness of radiotherapy and assess the impact of fd and TD in plantar fasciitis radiotherapy, we assessed 1624 irradiations (856 patients) performed using a fd of 1-3 Gy and a TD of 1-45 Gy. Analysis was carried out on the 623 irradiations (327 patients) for which complete follow-up data were available. The mean follow-up period was 74 months. The following parameters were evaluated: pain relief level; period of anaesthetic effect preservation after treatment; presence of pain and the timing of its appearance; and the intake of analgesic drugs at the last follow-up. After treatment, 48% of the patients reported a lack of pain, 21% reported pain relief greater than 50% and 17% reported pain relief less than 50%. The mean pain relief duration was 72 months. The last follow-up found that pain at rest afflicted 25% of the patients, and pain during walking afflicted 32%. A dose-effect relationship was not found. In conclusion, radiotherapy is an effective treatment for plantar fasciitis. A fd of 1.5 Gy and TD of 9 Gy should probably not be exceeded.

Abstract
Ocular involvement is common in pediatric rheumatologic diseases, supporting the concept that these conditions cannot be understood simply as isolated entities, but rather as multisystem disorders. The reasons for the breach of the eye-brain barrier and the targeting of the usually well-shielded eye during a pan-inflammatory process remains unclear. Pediatric rheumatologists should become familiar with these ocular disorders, because as important members of the treatment team, they manage more serious cases of inflammatory eye disease. A close collaboration between the treating rheumatologist and the ophthalmologist is essential to prevent potentially devastating outcomes. Therapeutic interventions such as topical steroids, systemic immunosuppressants, and biologics must balance the necessity of controlling ocular inflammation and the adverse effects of these treatments on a growing child.

Abstract
Among undifferentiated spondyloarthropathies (uSpA) are included incomplete forms or early phases of definite seronegative spondyloarthritides and cases of spondyloarthritides that remain undifferentiated. The treatment of all spondyloarthritides is more conditioned by the disease localisation, number of involved districts and severity of inflammation rather than by the subtype of the spondyloarthritides itself. Specific studies focused on the pharmacological approach to uSpA are scarce. As a consequence, many drugs are used on the basis of the experiences that have been gained in the treatment of other spondyloarthritides. At present, non-steroidal anti-inflammatory drugs/COX-2 inhibitors and disease-modifying antirheumatic drugs are the main therapeutic agents for the involvement of peripheral joints in uSpA. In those cases in which severe symptoms persist despite these treatments or when there is a severe axial involvement, antitumour necrosis factor agents represent an effective choice. In these patients, antitumour necrosis factor treatment raises the important possibility of blocking a shift from uSpA to differentiated severe forms of spondyloarthritides such as ankylosing spondylitis. Local administration of corticosteroids is useful when a small number of joints are involved, as is also the case for the extra-articular localisations of soft tissues.

Abstract
Juvenile onset spondyloarthropathy (SpA) is a term that refers to a group of human leucocyte antigen (HLA)-B27 associated inflammatory disorders affecting children under the age of 16 years, producing a continuum of clinical symptoms through adulthood. This disease is characterised by enthesopathy and arthropathy affecting the joints of the lower extremities and seronegativity for IgM rheumatoid factor and antinuclear antibodies. Children usually present with undifferentiated SpA and progress to differentiated forms over time. Except for the prevalence of some clinical features at onset, the pathogenic and clinical aspects of juvenile onset SpAs resemble those of the adult disease. Thus application of the same or similar therapeutic measures for both juvenile and adult onset SpAs seems logical. Current treatments for juvenile onset SpA provide symptomatic improvement, but do not alter disease progression. The increased expression of tumour necrosis factor alpha (TNFalpha) in synovial tissue of patients with adult and juvenile onset SpA and its correlation with infiltration of inflammatory mediators into the synovia suggest a significant pathogenic role of this cytokine. Clinical trials of anti-TNFalpha antibody (infliximab) therapy in patients with adult onset SpA have demonstrated significant clinical improvement in inflammatory pain, function, disease activity, and quality of life in correlation with histological and immunohistochemical evidence of modulation of synovial inflammatory processes. These promising findings suggest that anti-TNFalpha therapy may confer similar benefits in patients with juvenile onset SpA.

Abstract
This chapter reviews the clinical events that occur in patients with juvenile-onset spondyloarthritides (SpA) with the purpose of developing core sets, domains and instruments to evaluate disease activity and disease damage. We discuss several aspects, from concept and classification to clinical features and instruments already in use for measuring adult-onset SpA and childhood arthritides. Similarly, comparisons between juvenile-onset SpA, its adult counterpart, and other forms of juvenile arthritis are made to consider the adaptation of existing instruments or to develop specific ones.

Abstract
The juvenile-onset spondyloarthritides comprise a group of HLA-B27-associated disorders, which are mainly characterized by enthesitis and arthritis affecting the lower extremities, and in a variable proportion of cases, the sacroiliac and spinal joints. Additional features include a variety of extra-articular manifestations, and in some cases, bacterial infections as triggers. Except for the prevalence of some clinical features at onset and severity throughout the course of the disease, juvenile-onset SpA resemble their adult counterpart in most clinical aspects, strength of HLA-B27 association, and the role of arthritogenic bacteria in their pathogenesis. Not surprisingly, several aspects, from nomenclature to classification, and diagnostic criteria reflect to some extent those developed in the adult onset populations.

Abstract
OBJECTIVE To assess the frequency of sacroiliitis and the radiographic and clinical outcome in juvenile idiopathic arthritis (JIA) and determine patient characteristics, early disease variables, and genetic markers that predict development of sacroiliitis. METHODS We performed a retrospective cohort study of 314 (79%) of the 400 JIA patients first admitted to the hospital between 1980 and 1985. The participants were examined after a median disease duration of 14.9 years (range 11.7-25.1). Radiographs of the sacroiliac joints, hips, ankles, and tarsi were obtained and studied in a blinded manner by 2 radiologists. The presence of HLA-DRB1 and DPB1 alleles was determined by genotyping and that of HLA-B27 by serologic testing. Variables relating to the onset and course of the disease were obtained by chart reviews. RESULTS Twenty (6%) of the JIA patients developed radiographic sacroiliitis according to the New York criteria. In 9 patients (45%), sacroiliitis had not been demonstrated before the followup examination. At followup, spinal flexion (lateral and anterior) was reduced in 70-75% of patients with sacroiliitis and in 30-35% of those without sacroiliitis. Compared with the JIA patients without sacroiliitis, those with sacroiliitis more frequently had inflammatory back pain, enthesitis, radiographic changes in the hips and calcanei, erosions of any peripheral joint, and uveitis. Predictors of sacroiliitis were HLA-B27, absence of DPB1*02, hip joint involvement within the first 6 months, and disease onset after age 8 years. The following factors were more common among patients in whom sacroiliitis developed than in other JIA patients: DRB1*04, male sex, family history of ankylosing spondylitis, psoriasis, inflammatory back pain, and enthesitis within the first 6 months. CONCLUSION In the current study, radiographically evident sacroiliitis had developed in 6% of JIA patients after a median disease duration of 14.9 years. HLA-B27, absence of DPB1*02, late onset of disease, and early hip involvement were predictors of sacroiliitis.

Abstract
In the search for its role in inflammatory joint diseases, soluble HLA-DR (sHLA-DR) was quantitated in 72 synovial fluids (SF) by a newly established immunoenzyme assay. Unlike other soluble receptors which accumulated only moderately (sCD25, sCD4) or negligibly (sHLA class I, sCD8) in the SF, SF sHLA-DR levels exceeded serum levels by up to 3 orders of magnitude and varied disease dependently from "control" values (traumatic synovitis and osteoarthritis: 9.9 +/- 6.1 ng/ml). Clear-cut different SF sHLA-DR values in HLA-DR-associated "rheumatoid-like" (136.5 +/- 130.0 ng/ml) vs HLA-B27-associated "spondylarthropathy-like" arthritic forms (28.4 +/- 29.1 ng/ml) were most significant comparing oligoarticular juvenile chronic arthritis type I (147.6 +/- 112.6 ng/ml) and type II (3.3 +/- 1.1 ng/ml), thus offering a new classification marker. Also ex vivo, large amounts of sHLA-DR were released spontaneously by SF mononuclear cells and found to be related to the T-cell activation state. SF sHLA-DR may be shed in large complexes or micelles, as it eluted mainly at >450 kDa on gel filtration. Western blotting revealed that the majority of SF sHLA-DR consisted of full-length alpha- and beta-chains. Minor fractions of smaller sized antigens seemed to be generated by proteolytic cleavage rather than by alternative splicing, since only minute amounts of HLA-DRB mRNA lacking the transmembrane exon could be amplified by RT-PCR. Distinct forms of high-dose sHLA-DR, able to provoke rather than to suppress T-cell responses, are discussed as contributing to some HLA-DR disease association.

Abstract
The aim of this study was to investigate the efficacy and toxicity of sulphasalazine (SASP) in the treatment of children with chronic arthritis. The medical records of 36 children (25 boys, 11 girls) who received SASP for the treatment of chronic arthritis were reviewed. Twenty-one patients had juvenile spondyloarthropathies (JSA) (eight juvenile ankylosing spondylitis (JAS), 13 undifferentiated JSA (uJSA) and 15 had juvenile rheumatoid arthritis (JRA). The patients received SASP therapy for a mean of 2.5 years (range 3 weeks to 8.1 years). Clinical and laboratory data were reviewed retrospectively to determine the effects of treatment. A clinically significant response occurred in 23 (64%) children: remission in 14 (39%) (JRA 5, JSA 9) and improvement (25% reduction in joint count) in nine (25%) (JRA 4, JSA 5). There was no difference in response rate between JRA and JSA patients (p = 0.11), but the time to remission was shorter in JSA patients (mean 5 months) than in JRA patients (mean 25 months) (p = 0.024). Twelve of the 36 patients discontinued non-steroidal anti-inflammatory drugs, and six of eight patients discontinued prednisolone. A significant fall in erythrocyte sedimentation rate and rise in haemoglobin occurred in SASP-treated patients (p < 0.005) comparing most recent results with pretreatment levels. Side-effects occurred in four of 36 patients (11%); only one patient who had persisting severe diarrhoea required discontinuation of SASP. It was concluded that SASP appears to be effective and safe in the treatment of JRA and JSA patients. As a second-line agent, SASP is the drug of first choice for patients with JSA; for JRA patients SASP may be a useful, possibly less toxic alternative to methotrexate.

Abstract
Enthesitis is a distinctive pathological feature of spondyloarthropathy and may involve synovial joints, cartilaginous joints, syndesmoses and extra-articular entheses. This review focuses on peripheral extra-articular enthesitis which is a clinical hallmark of spondyloarthropathy. The entheses of the lower limbs are more frequently involved than those of the upper limbs, and heel enthesitis is the most frequent. Entheseal pain may be mild or moderate as well as severe and disabling. Peripheral enthesitis may be observed in all forms of spondyloarthropathy, including the undifferentiated ones, and may for a long time be the only long-standing clinical manifestation of the B27-associated disease process. Various imaging methods have been suggested for studying peripheral enthesitis. Ultrasonography and magnetic resonance imaging are the most useful because they may show alterations of the structures involved. Therapy of peripheral enthesitis consists of NSAIDs, orthoses and physical therapy. Steroid injections, second line drugs such as sulphasalazine and radiotherapy are reserved for more severe cases.

Abstract
Seronegative spondylarthropathies include ankylosing spondylitis, Reiter's syndrome and reactive arthritis, psoriatic arthritis, arthritis associated with ulcerative colitis and Crohn's disease, plus other forms which do not meet the criteria for definite categories and are called undifferentiated. Recently two sets of classification criteria have been proposed for the entire group including undifferentiated forms: the European Spondylarthropathy Study Group and the Amor criteria. The prevalence of spondylarthropathies is directly correlated with the prevalence of the HLA-B27 antigen in the population. The highest prevalence of ankylosing spondylitis (4.5%) has been found in Canadian Haida Indians, where 50% of the population is B27 positive. Among Europeans the frequency of the B27 antigen in the general population ranges from 3 to 13% and the prevalence of ankylosing spondylitis is estimated to be 0.1-0.23%. Seronegative spondylarthropathies have common clinical and radiologic manifestations: inflammatory spinal pain, sacroiliitis, chest wall pain, peripheral arthritis, peripheral enthesitis, dactylitis, lesions of the lung apices, conjunctivitis, uveitis and aortic incompetence together with conduction disturbances. All of these may also occur in isolation.

Abstract
The concept of spondyloarthropathies in childhood is emerging. It should now be more easily recognized since more specific diagnostic criteria are available for young patients. It probably accounts for about 20% of the whole group of chronic arthritides seen in paediatric rheumatology clinics. Juvenile ankylosing spondylitis stricto sensu is very rare in childhood. Most children who present with peripheral arthritis at onset meet the diagnostic criteria of undifferentiated spondylo-arthropathies such as those of the SEA syndrome, or those of the ESSG or Amor criteria. At follow-up, quite a large proportion of children may develop axial involvement. Psoriatic arthritis differs from the other spondyloarthropathies with a different sex ratio, and an earlier onset. The role of immunogenetic, environmental and ethnic factors are important for a better understanding of these diseases.

Abstract
This article discusses the clinical spectrum and characteristics of juvenile-onset spondyloarthropathies and includes a review of the demographic, clinical, radiographic (and other imaging techniques), and laboratory data of conditions, syndromes, and diseases making up this group. The pathogenic role of several factors in the context of adult-onset patients, but also in regards to studies already performed in juvenile-onset patients, is discussed.

Abstract
The goal of this work was to evaluate clinico-radiological correlation of enthesitis in SNSA patients, selected for presenting at least one radiological enthesopathy. Out of 50 patients with SNSA, 40 were selected for having had at least one radiological enthesitis. In a cross-sectional study, 32 males and 8 females, whose mean age was 40.4 years and mean disease duration 13 years, were evaluated. Nineteen patients had ankylosing spondylitis, 15 psoriatic arthritis and 6 Reiter's syndrome. Sites evaluated were pelvis and lower limbs. Radiological enthesopathies were identified by the presence of calcifications, new bone formation and/or erosions in tendinous and ligamentous insertion sites, and clinical enthesitis due to pain or tenderness and/or swelling at such locations. The site most commonly involved radiologically was the sciatic tuberosity in 33/40 cases, followed by the calcaneus with 12/40 on its inferior and 11/40 on its posterior aspect. Fifteen patients (37%) presented clinical manifestations at tendinous insertion sites, but clinico-radiological correlation was found in only 4 (22%). We conclude that clinical and radiological manifestations correlate poorly in SNSA enthesitis, perhaps due to the wide diversity of developmental stages of the disease.

Abstract
The opportunity to examine the defleshed skeleton of an individual diagnosed in life (Hamann-Todd collection, individual 2036) afforded a unique opportunity to demonstrate the bone damage characteristic of at least one form of juvenile rheumatoid arthritis (JRA). Characteristics helpful for recognition of JRA in archaeological material include peripheral articular marginal and subchondral erosions, axial (e.g., zygapophyseal or sacroiliac) joint erosions, fusion of axial (cervical zygapophyseal) and/or peripheral joints, premature epiphyseal closure and/or ballooned epiphyses, growth retardation with underdeveloped (short and overtubulated) long bones, short mandibular rami with underdeveloped condyles and concomitant micrognathia, and demineralization (osteopenia). Distinguishing between JRA and juvenile spondyloarthropathy, however, is not always possible, as illustrated by this case.

Abstract
The term spondyloarthropathy, currently used to describe some forms of idiopathic arthritis of childhood, may be inappropriate because most children included in this category do not have arthritis of the spine, and inflammatory disease of the sacroiliac joints is an infrequent or late finding. Juvenile AS, the archetype, or "complete" disease may account for only one fifth of the so-called "spondyloarthropathies". "Incomplete" or "early" spondyloarthropathies are most frequent. Such children may not develop axial symptoms and signs for 5 to 10 years after onset, and they may be better characterized as having enthesitis-related arthritis, a term proposed by a recent task force of the International League Against Rheumatism (ILAR). Reactive arthritis, although etiologically linked with the spondyloarthropathies, uncommonly progresses to AS in childhood; most patients have peripheral arthritis with or without enthesitis resolving in the relatively short term. The arthritis associated with IBD is more commonly peripheral than axial. Although axial disease undoubtedly occurs in JPsA, in the authors' experience it is very uncommon.

Abstract
OBJECTIVE To determine which early clinical data differentiate juvenile-onset ankylosing spondylitis (AS) from juvenile rheumatoid arthritis (JRA). METHODS Medical records of 35 patients with juvenile-onset AS and 75 with JRA (excluding type II pauciarticular JRA), all of whom had disease onset at age < or = 16 years, disease duration of < or = 2 1/2 years at the initial visit to the rheumatology clinic, and followup of > or = 10 years, were analyzed retrospectively with regard to features of disease found 6 months, 12 months, and 10 years after onset. RESULTS At 6 months, various features appeared more frequently in the juvenile-onset AS group than in the JRA group, i.e., pauciarthritis (54.3% versus 30.7%; P = 0.03, odds ratio [OR] = 2.7), enthesopathy (82.9% versus 0%; P < 0.0001, OR = 321.4), tarsal disease (71.4% versus 1.3%; P < 0.0001, OR = 185.0), and lumbar/sacroiliac symptoms (11.4% versus 0%; P = 0.02, OR = 11.9). At 12 months, the features found more frequently among juvenile-onset AS patients than JRA patients were enthesopathy (88.6% versus 4.0%; P < 0.0001, OR = 186.0), tarsal disease (85.7% versus 10.7%; P < 0.0001, OR = 50.3), and knee disease (100.0% versus 82.7%; P = 0.04, OR = 8.0). Involvement of the upper extremities (especially the hands) was found in significantly fewer juvenile-onset AS patients compared with the JRA group. Definite involvement of the spine and sacroiliitis in juvenile-onset AS occurred after a mean +/- SD of 7.3 +/- 2.0 years. CONCLUSION Regardless of axial disease, enthesopathy and tarsal disease in children who have arthritis of the lower, but not of the upper extremities differentiate juvenile-onset AS from JRA within 1 year of symptoms. The discriminative value of these parameters approaches that of axial disease (the gold standard) throughout the followup period.

Abstract
Three more cases of B27-positive patients who developed peripheral arthritis immediately after trauma are reported. The first had an exacerbation of arthritis in the right hip after falling from her motor-bike. The second had arthritis of the distal interphalangeal (DIP) joint of the right forefinger after shutting his finger in the door of his car. The third had arthritis of the right sternoclavicular joint after a road-accident while fastening her safety belt.

Abstract
Patients with juvenile spondyloarthropathy who carry HLA B27 antigen or have a family history of ankylosing spondylitis may have marked tarsometatarsal arthritis. This may be associated with hindfoot involvement and result in a supination deformity. Spontaneous fusion with complete obliteration of the tarsometatarsal joints may occur.
