Abortive Viral Infection Becomes Macrophage Activation Syndrome in Mice with Chronically Elevated Interleukin-18: Evidence for Synergy with Cytotoxic Impairment
Background/Purpose: Macrophage Activation Syndrome (MAS) and Hemophagocytic lymphohistiocytosis (HLH) are clinically similar life-threatening hyperinflammatory syndromes, often triggered by viral infection. HLH is associated with cytotoxic…Abstract Number: 982 • 2018 ACR/ARHP Annual Meeting
In the Presence of IL-18, IL-10 but Not IL-6 Induces IFN-γ Production and the Surface Expression of TRAIL on NK Cells
Background/Purpose: Adult-onset Still’s disease (AOSD) is a systemic inflammatory disease, the cause of which is largely unknown. AOSD has been recently classified as one of…Abstract Number: 923 • 2018 ACR/ARHP Annual Meeting
Neutrophils from Children with Systemic JIA Exhibit Persistent Proinflammatory Activation Despite Long-Standing Clinically Inactive Disease
Background/Purpose: Systemic juvenile idiopathic arthritis (SJIA) is a chronic childhood arthropathy with features of autoinflammation. New-onset SJIA is associated with expansion and activation of neutrophils…Abstract Number: 938 • 2017 ACR/ARHP Annual Meeting
A Germline Macrophage Activation Syndrome-Associated Nlrc4 Mutation Causes Chronic, Systemic, Non-Hematopoietic IL-18 Elevation and Intestinal MHC-II Upregulation
Background/Purpose: Patients prone to the development of Macrophage Activation Syndrome (MAS) can have extreme and often chronic elevation in the pro-inflammatory cytokine interleukin-18 (IL-18). In…Abstract Number: 1895 • 2017 ACR/ARHP Annual Meeting
Serum Interleukin 18 As a Biomarker for Systemic Juvenile Idiopathic Arthritis and Macrophage Activation Syndrome and Use of Recombinant Human IL-18 BP in a Patient with Refractory Disease
Background/Purpose: Systemic juvenile idiopathic arthritis is an autoinflammatory childhood arthritis with prominent innate immune activity. Macrophage activation syndrome is a severe and potentially fatal complication…Abstract Number: 1896 • 2017 ACR/ARHP Annual Meeting
IL-18 As a Diagnostic Biomarker, Differentiating Systemic JIA from Acute Leukaemia, Severe Bacterial Infections and Other Auto-Immune Disorders
Background/Purpose: Systemic onset Juvenile Idiopathic Arthritis (sJIA) is a disease characterized by systemic inflammation in addition to arthritis and it’s diagnosis currently still depends on…Abstract Number: 2772 • 2017 ACR/ARHP Annual Meeting
Unbound IL-18 Distinguishes Human Macrophage Activation Syndrome from Familial Hemophagocytic Lymphohistiocytosis and Affects Innate Versus Adaptive Murine Lymphocytes Differently
Background/Purpose: Persistently and extremely elevated serum IL-18 has been associated with Macrophage Activation Syndrome (MAS). Chronic IL-18 is hypothesized to contribute to excessive interferon (IFN)-g…Abstract Number: 142 • 2017 Pediatric Rheumatology Symposium
Neutrophils and monocytes in the early inflammatory cascade of systemic onset Juvenile Idiopathic Arthritis
Background/Purpose: Systemic onset Juvenile Idiopathic Artritis (sJIA) is an acquired systemic autoinflammatory disease characterized by spiking fever, arthritis and skin rash. Patients display high inflammatory…Abstract Number: 31 • 2017 Pediatric Rheumatology Symposium
Predicting therapy response to IL-1 blockade in systemic JIA: a biomarker search
Background/Purpose: Systemic onset juvenile idiopathic arthritis (sJIA) is an autoinflammatory disease, characterized by fever, rash and arthritis. The IL-1 and IL-6 pathway are crucial in…Abstract Number: 251 • 2016 ACR/ARHP Annual Meeting
Persistent Pruritic Skin Lesions with Dyskeratotic Cells in Upper Layer of Epidermis Are Specific and Associated with High Levels of Serum IL-18 in Adult-Onset Still’s Disease
Background/Purpose: Adult-onset Still’s disease (AOSD) is an acute and systemic inflammatory disorder that is characterized by high spiking fever, evanescent rash, arthralgia/arthritis and hyperferritinemia. However,…Abstract Number: 663 • 2016 ACR/ARHP Annual Meeting
Cytokine and Chemokine Levels in Serum and Tears As Disease Activity Biomarkers in Patients with Primary Sjögren´s Syndrome
