How to Effectively Diagnose & Treat Macrophage Activation Syndrome
“As a resident, [I] felt pretty terrible when [we had] a very sick child and the teams [couldn’t] agree on what to do,” said Lauren Henderson, MD, MMS, on an episode of ACR on Air. She discussed the importance of collaboration across specialties in the identification and treatment of macrophage activation syndrome (MAS).
New Options Emerge for Treating Macrophage Activation Syndrome
ATLANTA—Macrophage activation syndrome (MAS), a subset of hemophagocytic lymphohistiocytosis (HLH) disease, can be a fatal result of rheumatic disease. But there’s good news: New therapeutic options for refractory MAS targeting individual cytokines are emerging. At the 2019 ACR/ARP Annual Meeting, possible therapeutic options were presented during a pediatric-focused clinical and translational research track, Therapeutic Approaches…
Alterations in Macrophage Activation May Signal a Lupus Flare
New data suggest myeloid cells in SLE patients skew B and T cell activation status toward the M1 proinflammatory phenotype, thereby directing SLE flares and remission…
Research Links Macrophages with Pathogenesis of Inflammation, Fibrosis
MADRID—Research into pharmacodynamic biomarkers has shown that macrophages may have an important role in the pathogenesis of several diseases, including systemic sclerosis, an expert said at the 2017 Annual European Congress on Rheumatology (EULAR). The findings were discussed in a session that also covered how an understanding of M1 macrophages’ role in fibrosis has evolved…
The Role of Macrophages in Inflammation & Fibrosis: Macrophages May Predict Progressive Skin Disease
MADRID—Research into pharmacodynamic biomarkers has shown that macrophages may have an important role in the pathogenesis of several diseases, including systemic sclerosis, an expert said at the 2017 Annual European Congress on Rheumatology (EULAR).

New Criteria Released for Macrophage Activation Syndrome in Juvenile Idiopathic Arthritis
Although most systemic juvenile idiopathic arthritis patients don’t develop macrophage activation syndrome (MAS), the approximately 10% who do have this serious complication can experience widespread, massive inflammation, debilitating symptoms and even death. To improve understanding of MAS among physicians and advance efforts to develop effective therapies to treat it, a panel of 28 international pediatric…
2015 ACR/ARHP Annual Meeting: Macrophage Polarization and Its Role in Inflammatory Disease
SAN FRANCISCO—To unravel how out-of-control inflammation begins in rheumatoid arthritis and other diseases, one target for immunologists is the macrophage. Researchers discussed macrophage activation and other key drivers of inflammation at the 2015 ACR/ARHP Annual Meeting on Nov. 7. How macrophages behave when recognizing damage-associated molecular pathways (DAMPs) tells us more about why some inflammation doesn’t…
Researchers Find the Switch that Underlies Macrophage Metabolism
During pro-inflammatory stimulation, a recent study found HIF1α—not Myc—is required for the regulation of glycolysis in macrophages. Researchers examined macrophages and the distinct transcriptional programs engaged in response to mitogenic and pro-inflammatory stimulation…
