Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body. The disease may also affect other parts of the body, including skin, eyes, lungs, heart, nerves, and blood. This may result in a low red blood cell count, inflammation around the lungs, and inflammation around the heart. Fever and low energy may also be present. Often, symptoms come on gradually over weeks to months.
Rheumatology is a branch of medicine devoted to the diagnosis and management of disorders whose common feature is inflammation in the bones, muscles, joints, and internal organs. Rheumatology covers more than 100 different complex diseases, collectively known as rheumatic diseases, which includes many forms of arthritis as well as lupus and Sjögren's syndrome. Doctors who have undergone formal training in rheumatology are called rheumatologists.
Ankylosing spondylitis (AS) is a type of arthritis from the disease spectrum of axial spondyloarthritis. It is characterized by long-term inflammation of the joints of the spine, typically where the spine joins the pelvis. With AS, eye and bowel problems—as well as back pain—may occur. Joint mobility in the affected areas sometimes worsens over time. Ankylosing spondylitis is believed to involve a combination of genetic and environmental factors. More than 90% of people affected in the UK have a specific human leukocyte antigen known as the HLA-B27 antigen. The underlying mechanism is believed to be autoimmune or autoinflammatory. Diagnosis is based on symptoms with support from medical imaging and blood tests. AS is a type of seronegative spondyloarthropathy, meaning that tests show no presence of rheumatoid factor (RF) antibodies.
Disease-modifying antirheumatic drugs (DMARDs) comprise a category of otherwise unrelated disease-modifying drugs defined by their use in rheumatoid arthritis to slow down disease progression. The term is often used in contrast to nonsteroidal anti-inflammatory drugs and steroids.
Spondyloarthritis (SpA), also known as spondyloarthropathy, is a collection of clinical syndromes that are connected by genetic predisposition and clinical manifestations. The best-known clinical subtypes are enteropathic arthritis (EA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and reactive arthritis (ReA). Spondyloarthritis typically presents with inflammatory back pain and asymmetrical arthritis, primarily affecting the lower limbs, and enthesitis, inflammation at bone-adhering ligaments, tendons, or joint capsules.
Leflunomide, sold under the brand name Arava among others, is an immunosuppressive disease-modifying antirheumatic drug (DMARD), used in active moderate-to-severe rheumatoid arthritis and psoriatic arthritis. It is a pyrimidine synthesis inhibitor that works by inhibiting dihydroorotate dehydrogenase.
A nurse-led clinic is any outpatient clinic that is run or managed by registered nurses, usually nurse practitioners or Clinical Nurse Specialists in the UK. Nurse-led clinics have assumed distinct roles over the years, and examples exist within hospital outpatient departments, public health clinics and independent practice environments.
Golimumab, sold under the brand name Simponi, is a human monoclonal antibody which is used as an immunosuppressive medication. Golimumab targets tumor necrosis factor alpha (TNF-alpha), a pro-inflammatory molecule and hence is a TNF inhibitor. Profound reduction in C-reactive protein (CRP) levels, interleukin (IL)-6, intercellaular adhesion molecules (ICAM)-1, matrix metalloproteinase (MMP)-3, and vascular endothelial growth factor (VEGF) demonstrates golimumab as an effective modulator of inflammatory markers and bone metabolism. Golimumab is given via subcutaneous injection.
Patient education is a planned interactive learning process designed to support and enable expert patients to manage their life with a disease and/or optimise their health and well-being.
Aurotioprol is a gold salt used as an antirheumatic agent.
A rheumatoid nodule is a lump of tissue, or an area of swelling, that appears on the exterior of the skin usually around the olecranon or the interphalangeal joints, but can appear in other areas. There are four different types of rheumatoid nodules: subcutaneous rheumatoid nodules, cardiac nodules, pulmonary nodules, and central nervous systems nodules. These nodules occur almost exclusively in association with rheumatoid arthritis. Very rarely do rheumatoid nodules occur as rheumatoid nodulosis in the absence of rheumatoid arthritis. Rheumatoid nodules can also appear in areas of the body other than the skin. Less commonly they occur in the lining of the lungs or other internal organs. The occurrence of nodules in the lungs of miners exposed to silica dust was known as Caplan’s syndrome. Rarely, the nodules occur at diverse sites on body.
Anti-citrullinated protein antibodies (ACPAs) are autoantibodies that are directed against peptides and proteins that are citrullinated. They are present in the majority of patients with rheumatoid arthritis. Clinically, cyclic citrullinated peptides (CCP) are frequently used to detect these antibodies in patient serum or plasma.
Arthritis mutilans is a rare medical condition involving severe inflammation damaging the joints of the hands and feet, and resulting in deformation and problems with moving the affected areas; it can also affect the spine. As an uncommon arthropathy, arthritis mutilans was originally described as affecting the hands, feet, fingers, and/or toes, but can refer in general to severe derangement of any joint damaged by arthropathy. First described in modern medical literature by Marie and Leri in 1913, in the hands, arthritis mutilans is also known as opera glass hand, or chronic absorptive arthritis. Sometimes there is foot involvement in which toes shorten and on which painful calluses develop in a condition known as opera glass foot, or pied en lorgnette.
ACR score is a scale to measure change in rheumatoid arthritis symptoms. It is named after the American College of Rheumatology. The ACR score is more often used in clinical trials than in doctor patient-relationships, as it allows a common standard between researchers.
Enteropathic arthropathy commonly referred to as enteropathic arthritis, is a type of arthritis linked to Crohn's disease, ulcerative colitis, and chronic inflammatory bowel diseases.
The Rheumatoid Arthritis Quality of Life Questionnaire (RAQoL) is a disease-specific patient-reported outcome measure which determines the effect rheumatoid arthritis has on a patient's quality of life. The RAQoL has 30 items with a yes and no response format and takes about six minutes to complete.
The Psoriatic Arthritis Quality of Life (PsAQoL) measure is a disease specific patient-reported outcome measure which measures the effect that psoriatic arthritis has on a patient’s quality of life.
Axial spondyloarthritis is a chronic, immune-mediated disease predominantly affecting the axial skeleton. The term itself is an umbrella term characterizing a diverse disease family united by shared clinical and genetic features, such as the involvement of the axial skeleton. The 2009 introduced term axial spondyloarthritis is a preferred term nowadays and substitutes the old term ankylosing spondylitis.
Daniel Aletaha is an Austrian physician and professor of rheumatology. He has been head of the Department of Rheumatology at the Medical University of Vienna since 1 July 2019, and the President of the European Alliance of Associations for Rheumatology (EULAR) since 2023.
Iain Blair McInnes is a Scottish rheumatologist, Vice Principal and Head of the College of Medical, Veterinary and Life Sciences, Muirhead Chair of Medicine and Versus Arthritis Professor of Rheumatology at the University of Glasgow. His research has focused on inflammatory diseases, particularly rheumatoid arthritis and psoriatic arthritis.
