An interdisciplinary and collaborative environment is a critical factor for the advancement of basic science and clinical research in the academic environment, says William J. Koopman, MD, former director of the University of Alabama at Birmingham’s (UAB’s) Division of Clinical Immunology and Rheumatology. And in 1977, when he was being recruited by Division Director J….
The serine-threonine protein phosphatase 2A (PP2A) enzyme is critical for regulatory T cells to function—without it, they don’t have the ability to suppress effector T cells and can’t protect against autoimmunity, according to new research published in Nature Immunology. Researchers found that conditional knockout mice—in which PP2A expression is knocked out only in regulatory T cells—developed…
A variety of immune and nonimmune pathophysiologic mechanisms causing the disruption of alveolar capillaries with bleeding into the alveolar spaces can lead to diffuse alveolar hemorrhage (DAH). Immune-mediated mechanisms can cause DAH with or without the presence of capillaritis. The antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) syndromes—granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA)—are the…
May is recognized as National Arthritis Awareness Month, a time to bring attention to the more than 46 million Americans living with arthritis and related inflammatory diseases. In honor of the occasion, the Rheumatology Research Foundation is launching #RheumLife, a social media campaign to bring awareness to the severity of rheumatic disease. Through Twitter and…
April 5, 2016, marks a revolutionary day in the treatment of autoimmune diseases: The U.S. Food and Drug Administration (FDA) approved an infliximab (Remicade) biosimilar, known as Inflectra (infliximab-dyyb). Infliximab-dyyb, which is administered by intravenous infusion, is the first biosimilar drug approved to treat rheumatic disease in the U.S.1 Infliximab-dyyb has received approval for almost…
Psoriatic arthritis (PsA) is remarkably diverse in presentation and course. To assist clinicians in its management, the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) published treatment recommendations in 2009 based on a systematic evidence review. To be clinically relevant, such recommendations must be dynamic, and significant developments in PsA pathophysiology and disease assessment, particularly regarding the important contribution of comorbidities coupled with major therapeutic advances, necessitated an update of the GRAPPA recommendations…
The human intestinal microbiota is home to more than 1,000 bacterial species, containing approximately 3 million genes, many of which code for functions that have the potential to affect human physiology.1 Smaller numbers of organisms are also present in the skin, upper gastrointestinal tract, female reproductive tract and the oro- and nasopharynx. As tools have…
Arthritis is the primary cause of disability among U.S. military veterans and the second most common reason for medical discharge from the U.S. Army. One in three veterans is diagnosed with arthritis, compared with one in five members of the general U.S. population. It is important to keep in mind that these statistics reflect only…
Since 2005, the ACR’s Committee on Research has been responsible for advancing the research goals of the organization and providing leadership in research and research training in rheumatology via the ACR’s Research Agenda. The ACR Research Agenda is designed to address critical areas of research in rheumatic diseases, including the need for new technology, new…
The microbiome comprises diverse microbial flora, including bacteria, viruses and fungi, that live on mucosal surfaces, predominantly the skin and digestive tract. Microbes evolved billions of years prior to the development of modern Homo sapiens 200,000 years ago; we have always existed with their ubiquitous presence. Despite this, the first microbe was not visualized until…
