The purpose of the update was to expand the clinical scenarios for sJIA, to include recent data regarding the efficacy of the interleukin (IL)-1 and IL-6 inhibitors, to include macrophage activation syndrome (MAS), and to update the recommendations for follow-up tuberculosis (TB) screening for children receiving biologics. The recommendations were developed using the RAND-UCLA Appropriateness Methodology. The primary phenotypes addressed in the update were active systemic features with varying degrees of synovitis: synovitis without systemic features, sJIA with features of concern for MAS (considered as present or absent), and repeat TB screening for all JIA patients.\u003C\/p\u003E\u003Cp id=\u0022p-3\u0022\u003EFor children with active sJIA and varying degrees of synovitis, depending on active joint count (AJC; 0 joints, 1 to 4 joints, \u0026gt;4 joints) and physician assessment of disease activity (MD global) score (\u0026lt;5 or \u22655), first-line therapy options include anakinra, glucocorticoid monotherapy (oral or intravenous), or nonsteroidal anti-inflammatory drugs (NSAIDs). In patients with disease activity continuing after 1 month of anakinra treatment, clinicians should consider using canakinumab, tocilizumab, methotrexate (MTX) or leflunomide, or a tumor necrosis factor-\u03b1 (TNF-\u03b1) inhibitor depending on the AJC but irrespective of the MD global score. If initial therapy is glucocorticoid monotherapy and activity continues after 2 weeks of treatment, anakinra, canakinumab, tocilizumab, MTX, or leflunomide may be considered depending on MD global score. For disease activity continuing after 1 month of NSAIDs, using anakinra, glucocorticoids, canakinumab, or tocilizumab depending on MD global and AJC score may be considered. Adjunct systemic or intra-articular glucocorticoids are appropriate as needed.\u003C\/p\u003E\u003Cp id=\u0022p-4\u0022\u003EDepending on the AJC, first-line therapy options when there are no active systemic features and varying degrees of synovitis include MTX or leflunomide, NSAIDs, or intra-articular glucocorticoids depending on AJC. For cases of continued disease activity after 3 months of MTX or leflunomide consider using abatacept, anakinra, TNF-\u03b1 inhibitor, or tocilizumab. In patients with continued disease activity after 1 month of NSAIDs or intra-articular glucocorticoids, anakinra, MTX, or leflunomide should be considered.\u003C\/p\u003E\u003Cp id=\u0022p-5\u0022\u003EFor children with the third phenotype, sJIA and MAS, appropriate therapeutic options include anakinra, calcineurin inhibitors, and systemic glucocorticoids. These treatment options are not mutually exclusive.\u003C\/p\u003E\u003Cp id=\u0022p-6\u0022\u003EFor children in all JIA categories and those on biologics with an initial negative screen, the recommendation is for repeat TB screening at any point if the patient\u0027s risk has changed to moderate or high as determined by regional infectious disease guidelines.\u003C\/p\u003E\u003Cp id=\u0022p-7\u0022\u003EDr. Weiss noted that these phenotypes and scenarios do not address all possible sJIA presentations and that the recommendations are limited by the lack of a validated disease activity score, the low level of evidence for many recommendations, the absence of a specification of glucocorticoid dosing, route, or tapering, and the limited recommendations for MAS.\u003C\/p\u003E\u003Cp id=\u0022p-8\u0022\u003EEdward M. Behrens, MD, Children\u0027s Hospital of Philadelphia, University of Pennsylvania, Philadelphia, Pennsylvania, USA, reviewed the current knowledge concerning the MAS, a systemic inflammatory response syndrome occurring in \u223c10% of patients with sJIA that is characterized by coagulopathy, pan-cytopenia, hypotension, and multisystem organ failure. Labs for the condition include a falling erythrocyte sedimentation rate (ESR) and hyperferritinemia.\u003C\/p\u003E\u003Cp id=\u0022p-9\u0022\u003EAlthough MAS is one of several cytokine storm syndromes (CSS), Dr. Behrens cautioned that clinicians should not attempt to generalize from one CSS to another. As an example, he noted while familial hemophagocytic lymphohistiocytosis (fHLH) is caused by a genetic mutation that results in disease, usually in the first year of life, MAS is associated with an underlying illness and can present at the onset or anytime during the chronic course of disease. Further, the majority of patients with MAS do not have any homozygous defects and many do not have natural killer cell killing defects. Dr. Behrens speculated that MAS may arise from some relationship with sJIA.\u003C\/p\u003E\u003Cp id=\u0022p-10\u0022\u003EOccult (subclinical) MAS is identified in \u223c33% of patients with sJIA who undergo bone marrow assay and may be integral to the pathogenesis of sJIA [Behrens E et al. \u003Cem\u003EJ Rheumatol\u003C\/em\u003E 2007]. The characteristics of subclinical MAS include a systemic inflammatory response, frequently a response of the immune system to infection, hyperferritinemia, falling ESR despite inflammation, central nervous system inflammation, and the presence of hemophagocytosis.\u003C\/p\u003E\u003Cp id=\u0022p-11\u0022\u003EDr. Behrens suggested two scenarios: subclinical MAS may be a spectrum of disease of sJIA, in which all patients with SJIA have some element of MAS, or there may be two types of sJIA patients\u2014those that will get MAS and those that will not. Support for the former hypotheses comes from Fall and colleagues who identified, 225 differentially expressed genes in which cluster patterns correlated gene expression with serum ferritin levels [\u003Cem\u003EArthritis Rheum\u003C\/em\u003E 2007]. Support for the existence of two distinct types of patients may be found in a study by Shimizu and colleagues that indicates that cytokine profiling may predict subgroups of sJIA predisposed to MAS (\u003Ca id=\u0022xref-fig-1-1\u0022 class=\u0022xref-fig\u0022 href=\u0022#F1\u0022\u003EFigure 1\u003C\/a\u003E) [\u003Cem\u003ECytokine\u003C\/em\u003E 2013].\u003C\/p\u003E\u003Cdiv id=\u0022F1\u0022 class=\u0022fig pos-float  odd\u0022\u003E\u003Cdiv class=\u0022highwire-figure\u0022\u003E\u003Cdiv class=\u0022fig-inline-img-wrapper\u0022\u003E\u003Cdiv class=\u0022fig-inline-img\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/18\/8\/F1.large.jpg?width=800\u0026amp;height=600\u0026amp;carousel=1\u0022 title=\u0022Cytokines Predict Patients With sJIA Predisposed to MAS\u0022 class=\u0022fragment-images colorbox-load\u0022 rel=\u0022gallery-fragment-images-1792612362\u0022 data-figure-caption=\u0022Cytokines Predict Patients With sJIA Predisposed to MAS\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003E\u003Cimg class=\u0022fragment-image\u0022 alt=\u0022Figure 1.\u0022 src=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/18\/8\/F1.medium.gif\u0022\/\u003E\u003C\/a\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cul class=\u0022highwire-figure-links inline\u0022\u003E\u003Cli class=\u00220 first\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/18\/8\/F1.large.jpg?download=true\u0022 class=\u0022highwire-figure-link highwire-figure-link-download\u0022 title=\u0022Download Figure 1.\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload figure\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00221\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/18\/8\/F1.large.jpg\u0022 class=\u0022highwire-figure-link highwire-figure-link-newtab\u0022 target=\u0022_blank\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EOpen in new tab\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00222 last\u0022\u003E\u003Ca href=\u0022\/highwire\/powerpoint\/13851\u0022 class=\u0022highwire-figure-link highwire-figure-link-ppt\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload powerpoint\u003C\/a\u003E\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\u003Cdiv class=\u0022fig-caption attrib\u0022\u003E\u003Cspan class=\u0022fig-label\u0022\u003EFigure 1.\u003C\/span\u003E \n            \u003Cp id=\u0022p-12\u0022 class=\u0022first-child\u0022\u003ECytokines Predict Patients With sJIA Predisposed to MAS\u003C\/p\u003E\n         \u003Cq class=\u0022attrib\u0022 id=\u0022attrib-1\u0022\u003EIL=interleukin; MAS=macrophage activation syndrome; sJIA=systemic juvenile idiopathic arthritis.\u003C\/q\u003E\u003Cq class=\u0022attrib\u0022 id=\u0022attrib-2\u0022\u003EReproduced from Shimizu M et al.

They have a common clinical end-stage phenotype, but different mechanisms, and are likely to have different criteria for diagnosis.

Significant changes were also seen in white blood cell count (p=0.004), hemoglobin (p=0.002), platelet count (p=0.001), and ESR (p=0.001).\u003C\/p\u003E\u003Cdiv id=\u0022F2\u0022 class=\u0022fig pos-float  odd\u0022\u003E\u003Cdiv class=\u0022highwire-figure\u0022\u003E\u003Cdiv class=\u0022fig-inline-img-wrapper\u0022\u003E\u003Cdiv class=\u0022fig-inline-img\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/18\/8\/F2.large.jpg?width=800\u0026amp;height=600\u0026amp;carousel=1\u0022 title=\u0022Anakinra Reduces Fever and Arthritis in Patients With sJIA\u0022 class=\u0022fragment-images colorbox-load\u0022 rel=\u0022gallery-fragment-images-1792612362\u0022 data-figure-caption=\u0022Anakinra Reduces Fever and Arthritis in Patients With sJIA\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003E\u003Cimg class=\u0022fragment-image\u0022 alt=\u0022Figure 2.\u0022 src=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/18\/8\/F2.medium.gif\u0022\/\u003E\u003C\/a\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cul class=\u0022highwire-figure-links inline\u0022\u003E\u003Cli class=\u00220 first\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/18\/8\/F2.large.jpg?download=true\u0022 class=\u0022highwire-figure-link highwire-figure-link-download\u0022 title=\u0022Download Figure 2.\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload figure\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00221\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/18\/8\/F2.large.jpg\u0022 class=\u0022highwire-figure-link highwire-figure-link-newtab\u0022 target=\u0022_blank\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EOpen in new tab\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00222 last\u0022\u003E\u003Ca href=\u0022\/highwire\/powerpoint\/13852\u0022 class=\u0022highwire-figure-link highwire-figure-link-ppt\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload powerpoint\u003C\/a\u003E\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\u003Cdiv class=\u0022fig-caption attrib\u0022\u003E\u003Cspan class=\u0022fig-label\u0022\u003EFigure 2.\u003C\/span\u003E \n            \u003Cp id=\u0022p-15\u0022 class=\u0022first-child\u0022\u003EAnakinra Reduces Fever and Arthritis in Patients With sJIA\u003C\/p\u003E\n         \u003Cq class=\u0022attrib\u0022 id=\u0022attrib-3\u0022\u003EsJIA=systemic juvenile idiopathic arthritis.\u003C\/q\u003E\u003Cq class=\u0022attrib\u0022 id=\u0022attrib-4\u0022\u003EReproduced with permission from MG Punaro, MD.\u003C\/q\u003E\u003Cdiv class=\u0022sb-div caption-clear\u0022\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cp id=\u0022p-16\u0022\u003EDr. Punaro then reviewed unpublished data from the 51 children (including the original 13) with a blood gene-expression profile compatible with sJIA who were treated with anakinra (2.67 mg\/kg SC QD) for at least 1 week at her institution. After a median of 5 years of follow-up, 38 patients (75%) had inactive disease while clinical remission (on medication) was noted in 31 patients (60%). Eight patients (16%) patients had a partial response and 5 (10%) had no response. Minor complications associated with anakinra treatment included pain, burning with injection, injection-site reaction, infections, and influenza. There was one death and four patients developed MAS while on anakinra. MAS patients responded to treatment with increased anakinra and added steroids. Patients flaring after discontinuation of anakinra may not be responsive on re-treatment.\u003C\/p\u003E\u003Cp id=\u0022p-17\u0022\u003EDr. Punaro said that the IL-1 receptor antagonist, anakinra, is an effective, safe, and well-tolerated treatment for sJIA.\u003C\/p\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2013 MD Conference Express\u00ae\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/13\/18\/8.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_figures.js?nzo5i1\u0022\u003E\u003C\/script\u003E\n\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nzo5i1\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
