BACKGROUND: Prednisolone (PSL) has been suggested to be useful for the treatment of patients with Kawasaki disease (KD) resistant to intravenous immunoglobulin (IVIG). However, much remains to be elucidated regarding its proper use. METHODS: Two-stage multicenter prospective studies involving 1,087 subjects were performed to study the effects of acute phase therapy on IVIG-resistant KD. Subjects resistant to the first dose of IVIG were classified into high (≥ 10 mg/dL) and low (< 10 mg/dL) CRP groups according to serum CRP levels after the first dose of IVIG...

BACKGROUND AND PURPOSE: The optimal use of antiplatelet therapy for intracranial branch atheromatous disease (BAD) is not known. METHODS: We conducted a prospective multicenter, single-group trial of 144 consecutive patients diagnosed with probable BAD. All patients were treated within 12 h of symptom onset to prevent clinical progression using dual antiplatelet therapy with cilostazol plus one oral antiplatelet drug (aspirin or clopidogrel). Endpoints of progressive BAD in the dual therapy group at 2 weeks were compared with a matched historical control group of 142 patients treated with single oral antiplatelet therapy using either cilostazol, aspirin, or clopidogrel...

Although liver function test abnormality is frequently noted in children, there is no report about the distribution of the etiology and natural recovery time of the abnormal liver function. From March 2005 to February 2014, clinical information was retrospectively collected from 559 children who had abnormal liver function and were hospitalized or visited the outpatient clinic at the Jeju National University Hospital. The etiology of abnormal liver function was classified into groups and the natural recovery time of abnormal liver function was analyzed...

Background.  Pediatric Kawasaki disease (KD) and human immunodeficiency virus (HIV)(+) adult Kawasaki-like syndrome (KLS) are dramatic vasculitides with similar physical findings. Both syndromes include unusual arterial histopathology with immunoglobulin (Ig)A(+) plasma cells, and both impressively respond to pooled Ig therapy. Their distinctive presentations, histopathology, and therapeutic response suggest a common etiology. Because blood is in immediate contact with inflamed arteries, we investigated whether KD and KLS share an inflammatory signature in serum...

OBJECTIVE: Kawasaki disease (KD) is the leading cause of acquired heart disease among children in developed countries. Human KD coronary lesions are characterized by increased presence of infiltrating CD3(+) T cells, however the specific contributions of the different T cell subpopulations in coronary arteritis development remains unknown. Therefore, we sought to investigate the function of CD4(+) , CD8(+) , Regulatory T cells (TReg ), and NK T cells in the pathogenesis of the KD. METHODS AND RESULTS: T cell subsets function in KD development was addressed by using a well-established murine model of Lactobacillus casei cell wall extract (LCWE)-induced KD vasculitis...

Kawasaki disease (KD) is a multisystem vasculitis that predominantly targets the coronary arteries in children. Phenotypic similarities between KD and recurrent fever syndromes point to the potential role of inflammasome activation in KD. Mutations in NLRP3 are associated with recurrent fever/autoinflammatory syndromes. We show that the KD-associated genetic polymorphism in inositol-triphosphate 3-kinase C (ITPKC) (rs28493229) has important functional consequences, governing ITPKC protein levels and thereby intracellular calcium, which in turn regulates NLRP3 expression and production of IL-1β and IL-18...

Calprotectin, a heterodimer of S100A8 and S100A9, has been reported to be a useful biomarker in inflammatory bowel disease (IBD); however, the relationship between the fecal level of S100A9 and the extent of inflammation in IBD remains unclear. Our aim was to develop a new enzyme-linked immunosorbent assay (ELISA) for rat S100A9, and to investigate whether changes in fecal S100A9 levels reflect the inflammatory conditions in the intestinal tracts of rats with dextran sulfate sodium (DSS)-induced colitis. Anti-rat S100A9 monoclonal antibodies were raised in mice and used for the development of a novel ELISA for rat S100A9...

OBJECTIVES: To characterize patients experiencing late recurrence after primary radical surgery for renal cell carcinoma and to approach the mechanism of late recurrence. METHODS: We retrospectively analyzed 657 consecutive patients who underwent radical surgery for pathologically confirmed ≤stage III renal cell carcinoma in a single institution between January 1981 and December 2008. Early or late recurrence was defined as a recurrence occurring before or after 60 months after primary surgery...

BACKGROUND: Atopic dermatitis (AD) is a multifactorial inflammatory skin disease characterized by skin barrier dysfunction, allergic inflammation and intractable pruritus resistant to conventional antipruritic treatments, including H1-antihistamines. Granzymes (Gzms) are a family of serine proteases expressed by cytotoxic T lymphocytes and natural killer cells that have been shown to modulate inflammation. However, the relationship between Gzms and pathology in AD remains unclear. OBJECTIVE: This study assessed the correlation between plasma GzmB levels and severity of pruritus and dermatitis, in AD patients...

BACKGROUND: Kawasaki disease (KD) is the leading cause of acquired heart disease in children. Signal average electrocardiogram changes in patients during the acute phase of KD with coronary artery anomalies (CAA) include depolarization changes. We set out to determine if 12-lead-derived atrioventricular depolarization differences can identify CAA in patients with KD. METHODS: A blinded, retrospective case-control study of patients with KD was performed. Deep Q waves, corrected QT-intervals (QTc), spatial QRS-T angles, T-wave vector magnitudes (RMS-T), and a novel parameter for assessment of atrioventricular depolarization difference (the spatial PR angle) and a two dimensional PR angle were assessed...

Kawasaki disease is an acute, self-limited vasculitis of childhood and has become the leading cause of acquired pediatric heart disease in the USA. Prompt treatment is essential in reducing cardiac-related morbidity and mortality. The underlying etiology remains unknown. The disease itself may be the characteristic manifestation of a common pathway of immune-mediated vascular inflammation in susceptible hosts. The characteristic clinical features of fever for at least 5 days with bilateral nonpurulent conjunctivitis, rash, changes in lips and oral cavity, changes in peripheral extremities, and cervical lymphadenopathy remain the mainstay of diagnosis...

Netrin 1 was initially identified as an axon guidance factor and recent reports indicate that it inhibits chemokine-directed monocyte migration. Despite its importance as a neuroimmune guidance cue, the role of netrin 1 in osteoclasts is largely unknown. Here we detected high netrin 1 levels in the synovial fluid of rheumatoid arthritis patients. Netrin 1 is potently expressed in osteoblasts and synovial fibroblasts, and IL17 robustly enhances netrin 1 expression in these cells. The binding of netrin 1 to its receptor UNC5b on osteoclasts resulted in activation of SHP1, which inhibited VAV3 phosphorylation and RAC1 activation...

Perception of microbe-associated molecular patterns by host cell surface pattern recognition receptors (PRRs) triggers the intracellular activation of mitogen-activated protein kinase (MAPK) cascades. However, it is not known how PRRs transmit immune signals to MAPK cascades in plants. Here, we identify a complete phospho-signaling transduction pathway from PRR-mediated pathogen recognition to MAPK activation in plants. We found that the receptor-like cytoplasmic kinase PBL27 connects the chitin receptor complex CERK1-LYK5 and a MAPK cascade...

Importance: Kawasaki disease (KD) is the most recognized vasculitis of childhood. The condition's characteristic high fever, rash, mucositis, conjunctivitis, lymphadenopathy, and extremity changes are superficially unexceptional, and resolve spontaneously within a mean of 12 days. It is the acuity and the potential for life-changing damage to the coronary arteries that distinguish KD from conditions that mimic it and exemplify the unique aspects and challenges of vascular inflammation in children...

Kawasaki disease (KD) is an acute, self-limiting, medium-vessel vasculitis that occurs predominantly in young children. The treatment of KD consists of intravenous immunoglobulin (IVIG) along with aspirin and, in IVIG-resistant cases, corticosteroids. Crystalline keratopathy with corneal deposition of the immunoglobulin is a rare complication of IVIG therapy. We report the case of a 12-year-old girl who received IVIG for KD and developed visual complaints, which were attributable to crystalline keratopathy and corneal edema...
