Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) is a heterogeneous group of 7 chronic arthritides categories that affects children younger than 16 years. This case series elucidates the characteristics of patients from a single center diagnosed with JIA at younger than 12 months. METHODS We included patients who presented to the rheumatology clinic for JIA with symptom onset at younger than 1 year. Chart review was conducted to complete case report forms that included demographics, historical features, examination features, laboratory results, imaging results, and treatment courses. RESULTS We identified 12 patients who met our inclusion criteria. Eight of our patients were diagnosed with oligoarticular JIA, 3 had polyarticular JIA, and 1 was diagnosed with systemic JIA. Overall, 58% (7/12) of patients had joint contractures at their initial visit. Of the patients with oligoarticular JIA, 50% (4/8) required a disease-modifying antirheumatic drug to achieve disease remission; 12.5% (1/8) required biologic therapy. All of the polyarticular JIA patients had highly positive antinuclear antibodies, as well as elevated inflammatory markers. CONCLUSIONS Children with infantile JIA are overall similar to the larger population of patients with JIA. Disease severity may not be different compared with that of older children with JIA; however, there is likely a larger delay in diagnosis and the presence of contractures, which occurred in more than half of our patients.

Abstract
BACKGROUND Kawasaki disease (KD) is a pediatric inflammatory disorder causes coronary artery complications. The disease overlapping manifestations with a set of symptomatically like diseases such as bacterial and viral infections, juvenile idiopathic arthritis, Henoch-Schönlein purpura, infection of unknown etiology, group-A streptococcal and adenoviral infections, and incomplete KD could lead to misdiagnosis of the disease. METHODS In the present study, we applied weighted gene co-expression network analysis (WGCNA) to identify network modules of co-expressed genes in GSE73464 and also, limma package was used to identify the differentially expressed genes (DEGs) in KD expression arrays composed of GSE73464, GSE18606, GSE109351, and GSE68004. By merging the results of WGCNA and limma, we detected hub genes. Then, analyzed the peripheral blood mononuclear cells (PBMCs) of 16 patients and 8 control subjects using Real-Time Polymerase Chain Reaction (RT-PCR) to evaluate the previous results. RESULTS We assessed the diagnostic potency of the screened genes by plotting the area under curve (AUC). We finally identified 2 genes CASP5(Caspase 5) and CR1(Complement C3b/C4b Receptor 1) which were shown to potentially discriminate KD from other similar diseases and also from healthy people. CONCLUSIONS The results of RT-PCR and AUC confirmed the diagnostic potentials of two suggested biomarkers for KD.

Abstract
OBJECTIVES Kawasaki disease (kDa) is an immune-mediated vasculitis of childhood with multi-organ inflammation. We determined the risk of subsequent immune-mediated inflammatory disease (IMID), including arthritis, type 1 diabetes, inflammatory bowel disease (IBD), autoimmune liver disease (ALD), primary sclerosing cholangitis (PSC) and multiple sclerosis (MS). METHODS We conducted a matched population-based cohort study using health administrative data from Ontario, Canada. Children aged <18 years born between 1991-2016 diagnosed with kDa (n = 3,753) were matched to 5 non-kDa controls from the general population (n = 18 749). We determined the incidence of IMIDs after resolution of kDa. Three- and 12-month washout periods were used to exclude kDa-related symptoms. RESULTS There was an elevated risk of arthritis in kDa patients compared with non-kDa controls starting three months after index date (103.0 vs 12.7 per 100 000 person-years (PYs); incidence rate ratio (IRR) 8.07 (95% CI 4.95-13.2); hazard ratio (HR) 8.08 (95% CI 4.95-13.2), resulting in the overall incidence of IMIDs being elevated in kDa patients (175.1 vs 68.0 per 100 000 PYs; IRR 2.58 (95% CI 1.93-3.43); HR 2.58, 95% CI 1.94-3.43). However, there was no increased risk for diabetes, IBD, ALD, PSC or MS in kDa patients. Similar results were observed using a 12-month washout period. CONCLUSIONS Children diagnosed with kDa were at increased risk of arthritis following the acute kDa event, but not other IMIDs. Health care providers should monitor for arthritis in children following a diagnosis of kDa.

Abstract
BACKGROUND Kawasaki disease (KD) is an acute systemic vasculitis that predominantly affects patients younger than 5 years. In the absence of an available, affordable diagnostic test, detailed clinical history and physical examination are still fundamental to make a diagnosis. METHODS We present five representative cases with KD-like presentations: systemic onset juvenile idiopathic arthritis, mycoplasma-induced rash and mucositis, staphylococcal scalded skin syndrome, BCGosis, and the recently described multisystemic inflammatory syndrome in children (MIS-C) associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) virus. RESULTS Rash, fever, and laboratory markers of inflammation can be present in several childhood diseases that may mimic KD. CONCLUSION The term 'Kawasaki syndrome' instead of 'Kawasaki disease' may be more appropriate. Physicians should consider an alternative diagnosis that may mimic KD, particularly considering MIS-C during the present pandemic, as an aggressive diagnostic and therapeutic approach is needed.

Abstract
Objective To screen for immune genes that play a major role in Kawasaki disease and to investigate the pathogenesis of Kawasaki disease through bioinformatics analysis. Methods Kawasaki disease‐related datasets GSE18606, GSE68004, and GSE73461 were downloaded from the Gene Expression Omnibus database. Three microarrays were integrated and standardized to include 173 Kawasaki disease samples and 101 normal samples. The samples were analyzed using CIBERSORT to obtain the infiltration of 22 immune cells and analyze the differential immune cells in the samples and correlations. The distribution of the samples was analyzed using principal component analysis (PCA). Immune‐related genes were downloaded, extracted from the screened samples and analyzed for differential analysis (different expression genes [DEG]) and weighted gene co‐expression network analysis (WGCNA). We constructed coexpression networks, and used the cytohobbe tool in Cytoscape to analyze the coexpression networks and select the immune genes that played a key role in them. Results Immune cell infiltration analysis showed that B cells naive, T cells CD8, natural killer (NK) cells activated, and so forth were highly expressed in normal samples. T cells CD4 memory activated, monocytes, neutrophils, and so forth were highly expressed in Kawasaki disease samples. PCA results showed a significant difference in the distribution of normal and Kawasaki disease samples. From the screened samples, 97 upregulated and 103 downregulated immune‐related genes were extracted. WGCNA analysis of DEG yielded 10 gene modules, of which the three most relevant to Kawasaki disease were red, yellow, and gray modules. They were associated with cytokine regulation, T‐cell activation, presentation of T‐cell receptor signaling pathways, and NK cell‐mediated cytotoxicity. CXCL8, CCL5, CCR7, CXCR3, and CCR1 were identified as key genes by constructing a coexpression network. Conclusion Our study shows that we can distinguish normal samples from Kawasaki disease samples based on the infiltration of immune cells, and that CXCL8, CCL5, CCR7, CXCR3, and CCR1 may play important roles in the development of Kawasaki disease.

Abstract
Kawasaki disease (KD) is associated with several musculoskeletal manifestations. Although arthritis has been reported to occur in 2.3-31% of children with KD, there is paucity of detailed studies on the subject. We report our experience on arthritis in children with KD. Data were collated from a review of records of patients diagnosed with KD and arthritis during the period January 1994-June 2019. Eight hundred sixty-five children (male:female 29:11) were diagnosed with KD during this period-of these, 40 (4.6%) had arthritis. Median day of diagnosis of KD was 17 days. Twenty-nine (72.5%), 8 (20%), and 3 (8.6%) children developed arthritis in acute, subacute, and convalescent phases of KD, respectively. Oligoarticular involvement was observed in 32 (80%) children and among these, 7 (20%) had monoarthritis. Predominant joints involved were knee (74.3%), ankle (40%), and hip (28.6%). Thirty-two children (80%) were treated with non-steroidal anti-inflammatory drugs (NSAIDs). Median duration of arthritis was 10 days (range, 2-180 days) with uneventful recovery in all cases. Three (7.5%) children had coronary artery ectasia which regressed on follow-up.Conclusion: Arthritis in KD is usually non-erosive, self-limiting, and responds well to a short course of NSAIDs.What is Known:• Arthritis has been reported to occur in 2.3-31% of children with KD.• Arthritis in KD is usually oligoarticular, non-erosive, and responds well to short course of non-steroidal anti-inflammatory drugs.What is New:• Children with KD and arthritis do not appear to be at increased risk of development of coronary artery abnormalities.• Arthritis in children with KD can result in diagnostic confusion, and diagnosis of KD may get delayed.

Abstract
Introduction: Kawasaki disease (KD) is one of the commonest pediatric vasculitides and is associated with a significant risk of development of coronary artery abnormalities if left untreated. Areas covered: In this review, we have highlighted the incomplete and unusual presentations of KD and also emphasize the controversies pertaining to 2D echocardiography in KD. A PubMed search was performed regarding diagnosis and unusual presentations of KD. Expert opinion: Diagnosis of KD is essentially clinical and based on recognition of typical clinical features that may appear sequentially and all signs and symptoms may not be present at one point of time. There is no confirmatory laboratory test for diagnosis of this condition. Further complicating the picture is the fact that incomplete and atypical forms KD may be seen in up to 50% patients. Although 2D echocardiography continues to be the preferred imaging modality for cardiac assessment in patients with KD, it has its limitations.

Abstract
Kawasaki disease (KD) has features that appear supporting an infectious cause with a secondary deranged inflammatory/autoimmune response. The association of KD in adults with human immunodeficiency virus infection and the presence of KD in patients with immunodeficiency disorders support the infectious theory. We present four KD patients associated with immunodeficiencies: one with X-linked agammaglobulinemia, one with HIV infection, and two with leukemia; one of these patients also had Down syndrome. We did a literature search to find out all reported cases of immunodeficiency with KD in children. In immunodeficiency disorders, the inability of the immune system to eradicate the pathogens coupled to an exaggerated inflammatory response, especially in chronic granulomatous disease, may lead to the development of KD. The study of patients with immunodeficiencies complicated with KD may shed light into the etiopathogenesis of the disease.

Abstract
The present study was conducted to screen serum exosomal microRNAs (miRNAs) for the early diagnosis of Kawasaki disease (KD) and to investigate their underlying mechanisms by analyzing microarray data under accession numbers GSE60965 [exosomal miRNA, including three pooled serum samples from 5 healthy children, 5 patients with KD and 5 patients with KD following intravenous immunoglobulin (IVIG) therapy] and GSE73577 (mRNA, including peripheral blood mononuclear cell samples from 19 patients with KD prior to and following IVIG treatment) from the Gene Expression Omnibus database. Differentially expressed miRNAs (DE-miRNAs) and genes (DEGs) were identified using the Linear Models for Microarray data method, and the mRNA targets of DE-miRNAs were predicted using the miRWalk 2.0 database. The functions of the target genes were analyzed using the Database for Annotation, Visualization and Integrated Discovery (DAVID). As a result, 65 DE-miRNAs were identified with different expression patterns between the healthy children and patients with KD and between patients with KD and patients with KD following IVIG therapy. The target genes of 15 common DE-miRNAs were predicted. Following overlapping the target genes of DE-miRNAs with 355 DEGs, 28 common genes were identified and further screened to construct a network containing 30 miRNA-mRNA regulatory associations. Of these associations, only miR-328-spectrin α, erythrocytic 1, miR-575-cyclic AMP-responsive element-binding protein 5/b-1,4-galactosyltransferase 5/WD repeat and FYVE domain-containing 3/cystatin-A/C-X-C motif chemokine receptor 1/protein phosphatase 1 regulatory subunit 3B, miR-134-acyl-CoA synthetase long chain family member 1/C-type lectin domain family 1 member A and miR-671-5p-tripartite motif containing 25/leucine rich repeat kinase 2/kinesin family member 1B/leucine rich repeat neuronal 1 were involved in the negative regulation of gene expression. Functional analysis indicated that the identified target genes may be associated with inflammation. Accordingly, serum exosomal miR-328, miR-575, miR-134 and miR-671-5p may act as potential biomarkers for the diagnosis of KD and the prediction of outcomes of the IVIG therapy by influencing the expression of inflammatory genes.

Abstract
Kawasaki disease (KD) is an acute systemic vasculitis of childhood that does not have a known cause or aetiology. The epidemiological features (existence of epidemics, community outbreaks and seasonality), unique age distribution and clinical symptoms and signs of KD suggest that the disease is caused by one or more infectious environmental triggers. However, KD is not transmitted person-to-person and does not occur in clusters within households, schools or nurseries. KD is a self-limited illness that is not associated with the production of autoantibodies or the deposition of immune complexes, and it rarely recurs. Regarding the underlying pathophysiology of KD, innate immune activity (the inflammasome) is believed to play a role in the development of KD vasculitis, based on the results of studies with animal models and the clinical and laboratory findings of KD patients. Animal studies have demonstrated that innate immune pathogen-associated molecular patterns (PAMPs) can cause vasculitis independently of acquired immunity and have provided valuable insights regarding the underlying mechanisms of this phenomenon. To validate this concept, we recently searched for KD-specific PAMPs and identified such molecules with high specificity and sensitivity. These molecules have structures similar to those of microbe-associated molecular patterns (MAMPs), as shown by liquid chromatography-tandem mass spectrometry. We propose herein that KD is an innate immune disorder resulting from the exposure of a genetically predisposed individual to microbe-derived innate immune stimulants and that it is not a typical infectious disease.

Abstract
OBJECTIVES To estimate the incidence of systemic-onset juvenile idiopathic arthritis (SoJIA) within 6 months after treatment for presumed Kawasaki disease (KD) (presumed patients with KD with subsequent diagnosis of SoJIA [pKD/SoJIA]) and describe presentation differences from sole KD. STUDY DESIGN We identified patients treated for KD at Nationwide Children's Hospital and from the Pediatric Health Information System from 2009-2013. We then identified the subset of children, pKD/SoJIA, who received an International Classification of Diseases, Ninth Revision code for SoJIA and had it listed at least once 3 months after and within 6 months after KD diagnosis. Demographic characteristics, readmission rates, treatments, and complications were noted. A literature review was also performed to identify clinical, laboratory, and echocardiographic data of previously documented patients with KD later diagnosed with SoJIA. RESULTS There were 6745 total treated patients with KD in the Pediatric Health Information System database during the study period; 10 patients were identified to have pKD/SoJIA (0.2% of cohort). Those with pKD/SoJIA were predominantly Caucasian compared with patients with KD (90% and 46.8%, respectively; P=.003). Macrophage activation syndrome was more common in patients with pKD/SoJIA than in sole patients with KD (30% and 0.30%, respectively; P<.001). Fifteen cases of pKD/SoJIA were identified by literature and chart review, 12 of whom were initially diagnosed with incomplete KD. CONCLUSIONS We reported a 0.2% incidence of pKD/SoJIA, which was associated with Caucasian race, macrophage activation syndrome, and an incomplete KD phenotype.

Abstract
The authors report an 18-mo-old girl who presented with features of incomplete Kawasaki disease and was refractory to intravenous immunoglobulin and infliximab treatment. She subsequently responded to pulse intravenous methylprednisolone therapy. The diagnostic dilemma arose after 2 mo when she developed clinical features suggestive of systemic onset juvenile idiopathic arthritis. Since both diseases have overlapping clinical features and no specific diagnostic laboratory tests, it is difficult for the clinicians even in the best of centers to reach a definitive diagnosis as illustrated by the index case.

Abstract
BACKGROUND In the absence of a specific test, the diagnosis of clinically incomplete Kawasaki disease (KD) can be challenging. The 2004 American Heart Association guidelines state that the diagnosis of KD is supported by the presence of coronary artery dilation documented by echocardiography. However, the specificity of coronary artery dilation and its prevalence in children with other acute illnesses associated with fever has not been studied. METHODS A 2-center, prospective study compared the internal diameters and Z-scores (standard deviation [SD] units from the mean internal diameter normalized for body surface area) of the proximal left anterior descending and right coronary arteries measured by echocardiography in febrile children (FC) and children with KD. RESULTS The median Z-score (interquartile range) of the left anterior descending coronary artery was -0.05 (-0.86, 0.62) and 1.06 (0.36, 2.06) SD units for the 45 FC and the 145 KD patients, respectively (P < 0.0001). For the right coronary artery, the median Z-score was 0.21 (-0.20, 0.87) and 1.04 (0.31, 1.85) SD units for the FC and KD patients, respectively (P < 0.0001). There was no correlation between body temperature at the time of echocardiography and coronary artery Z-score. No febrile child had a coronary artery Z-score ≥ 2.5 SD units. CONCLUSIONS Z-scores ≥ 2.5 SD units were not observed in our cohort of FC. Therefore, echocardiographic evidence of coronary artery dilation can be used to support the diagnosis of KD.

Abstract
More than 40 years have passed since Kawasaki syndrome (KS) was first described. Yet KS still remains an enigmatic illness which damages the coronary arteries in a quarter of untreated patients and is the most common cause of childhood-acquired heart disease in developed countries. Many gaps exist in our knowledge of the etiology and pathogenesis of KS, making improvements in therapy difficult. In addition, many KS features and issues still demand further efforts to achieve a much better understanding of the disease. Some of these problem areas include coronary artery injuries in children not fulfilling the classic diagnostic criteria, genetic predisposition to KS, unpredictable ineffectiveness of current therapy in some cases, vascular dysfunction in patients not showing echocardiographic evidence of coronary artery abnormalities in the acute phase of KS, and risk of potential premature atherosclerosis. Also, the lack of specific laboratory tests for early identification of the atypical and incomplete cases, especially in infants, is one of the main obstacles to beginning treatment early and thereby decreasing the incidence of cardiovascular involvement. Transthoracic echocardiography remains the gold-standard for evaluation of coronary arteries in the acute phase and follow-up. In KS patients with severe vascular complications, more costly and potentially invasive investigations such as coronary CT angiography and MRI may be necessary. As children with KS with or without heart involvement become adolescents and adults, the recognition and treatment of the potential long term sequelae become crucial, requiring that rheumatologists, infectious disease specialists, and cardiologists cooperate to develop specific guidelines for a proper evaluation and management of these patients. More education is needed for physicians and other professionals about how to recognize the long-term impact of systemic problems related to KS.

Abstract
Kawasaki disease (KD) is the most common systemic vasculitis in childhood after Henoch-Schonlein purpura, and the most common cause of acquired heart disease among children living in Western countries. Its diagnosis relies on clinical findings; laboratory tests are useful to rule out other causes of unexplained fever but are not specific for the diagnosis of KD. Numerous efforts to produce a diagnostic algorithm have been made, but without success. Expert opinion is therefore required in doubtful cases, especially those that lack classical criteria (the so-called atypical or incomplete cases). Renal, gastrointestinal, neurologic, pulmonary and ocular involvements have all been described. Infants may be at higher risk of complications since recognising manifestations of the disease might be more difficult in this group. Approaches to treatment and follow-up of KD are changing in parallel with changes in concepts of what constitutes classical and incomplete KD. Guiding this evolution is the probability that the diagnosis is actually KD, the duration of the child's illness and the desired effects of therapy. Until a gold standard for diagnosing KD is available, these therapeutic decisions will continue to be made on an individual basis.

Abstract
Kawasaki disease is an acute febrile condition seen in children. However, it is also well recognized that some patients do not fulfill the classic diagnostic criteria for the diagnosis of kawasaki disease. The incomplete form of kawasaki disease is termed as ‘Incomplete KD’ or ‘Atypical KD’. We present a case of a 6 year old child with a history of prolonged fever, periorbital, oral and lip changes, changes in the extremities and an erythamatous, maculopapular rash. Based on the physical exam and her echocardiogram that showed right coronary artery dilatation, Intravenous immune globulin was administered in this patient. This patient was refractory to two doses of intravenous immune globulin and therefore was started on methylprednisolone, to which she responded dramatically. The diagnostic dilemma primarily arose when this child presented with joint pain a day after her discharge from the hospital and a positive laboratory workup. So, was this a case of incomplete Kawasaki refractory to intravenous immuno globulin therapy or systemic juvenile idiopathic arthritis? We suggest that physicians should be cognizant of the fact that they must individualize every patient’s management to the best of their knowledge and judgment, rather than merely going by the guidelines.
