** **Rheumatoid Arthritis (RA)** is a chronic autoimmune disorder characterized by inflammation and degeneration of the joints, leading to pain, stiffness, and limited mobility. **CONTENT:** ### **Overview** Rheumatoid Arthritis (RA) is a complex and multifaceted condition that affects millions of people worldwide. It is a chronic autoimmune disorder, meaning that the body's immune system mistakenly attacks its own tissues, leading to inflammation and damage to the joints. RA can affect any joint, but it most commonly affects the hands, feet, wrists, elbows, knees, and ankles. The symptoms of RA can be debilitating, causing pain, stiffness, and limited mobility, making everyday activities a challenge. RA is a systemic disease, meaning that it can affect multiple systems in the body, including the musculoskeletal, nervous, and cardiovascular systems. In addition to joint damage, RA can also cause inflammation in other parts of the body, such as the eyes, lungs, and skin. If left untreated, RA can lead to significant disability and a reduced quality of life. ### **History/Background** The exact cause of RA is still unknown, but research suggests that it is a combination of genetic and environmental factors. The first recorded description of RA dates back to 1800 BC, in the Ebers Papyrus, an ancient Egyptian medical text. However, it wasn't until the 19th century that RA was formally described as a distinct medical condition. In the early 20th century, the discovery of the rheumatoid factor (RF) antibody, which is present in the blood of most people with RA, marked a significant milestone in the understanding of the disease. The development of disease-modifying antirheumatic drugs (DMARDs) in the mid-20th century revolutionized the treatment of RA, allowing for the control of symptoms and slowing of disease progression. ### **Key Information** RA is characterized by several key features, including: * **Joint inflammation**: RA causes inflammation in the joints, leading to pain, stiffness, and swelling. * **Joint damage**: The inflammation and swelling caused by RA can lead to permanent damage to the joints, including cartilage loss and bone erosion. * **Systemic symptoms**: RA can cause inflammation in other parts of the body, including the eyes, lungs, and skin. * **Autoantibodies**: RA is characterized by the presence of autoantibodies, such as RF and anti-CCP antibodies, which are present in the blood of most people with the disease. The diagnosis of RA is typically made based on a combination of clinical evaluation, laboratory tests, and imaging studies. The American College of Rheumatology (ACR) has established a set of criteria for the diagnosis of RA, which includes the presence of joint inflammation, systemic symptoms, and the presence of autoantibodies. ### **Significance** RA is a significant public health concern, affecting millions of people worldwide. The impact of RA on quality of life, productivity, and healthcare costs is substantial. According to the Arthritis Foundation, RA costs the US healthcare system over $20 billion annually. In addition to its impact on individuals, RA also has significant economic and social implications. The loss of productivity and the need for medical care and treatment can have a significant impact on families and communities. **INFOBOX:** - Name: Rheumatoid Arthritis (RA) - Type: Autoimmune disorder - Date: 1800 BC (first recorded description) - Location: Global - Known For: Chronic joint inflammation and damage **TAGS:** Rheumatoid Arthritis, Autoimmune disorder, Joint inflammation, Joint damage, Systemic symptoms, Autoantibodies, Diagnosis, Treatment, Public health concern.

** This encyclopedia entry is about **Rheumatoid Arthritis (RA)**, a chronic autoimmune disorder that causes inflammation and pain in the joints. **CONTENT** ### Overview Rheumatoid Arthritis (RA) is a complex and multifaceted condition that affects millions of people worldwide. It is a chronic autoimmune disorder that causes inflammation and pain in the joints, leading to stiffness, swelling, and deformity. RA is a systemic disease, meaning it can affect multiple systems in the body, including the skin, eyes, lungs, heart, and blood vessels. Despite significant advances in treatment and management, RA remains a significant public health concern, with a substantial impact on quality of life, productivity, and economic burden. RA is characterized by a combination of genetic and environmental factors, which trigger an abnormal immune response that leads to inflammation and joint damage. The exact cause of RA is still not fully understood, but research suggests that a combination of genetic predisposition, hormonal influences, and environmental triggers, such as infections or stress, may contribute to the development of the disease. ### History/Background The history of RA dates back to ancient civilizations, with descriptions of joint inflammation and pain found in the writings of Hippocrates and Galen. However, it wasn't until the 19th century that RA was formally described as a distinct medical condition. The term "rheumatoid arthritis" was first coined in 1859 by British physician Alfred Baring Garrod, who recognized the disease as a chronic and debilitating condition that affected the joints. In the early 20th century, the discovery of the rheumatoid factor (RF) antibody marked a significant breakthrough in understanding RA. RF is a protein that is produced by the immune system in response to inflammation and is often present in people with RA. The development of more sensitive tests for RF and other biomarkers, such as anti-citrullinated protein antibodies (ACPAs), has improved diagnosis and monitoring of the disease. ### Key Information **Key Facts:** * RA affects approximately 1% of the global population, with women being more likely to develop the disease than men. * The disease typically affects people between the ages of 30 and 60, although it can occur at any age. * RA is a systemic disease, meaning it can affect multiple systems in the body, including the skin, eyes, lungs, heart, and blood vessels. * The disease is characterized by a combination of genetic and environmental factors, which trigger an abnormal immune response that leads to inflammation and joint damage. * Treatment for RA typically involves a combination of medications, including disease-modifying antirheumatic drugs (DMARDs), biologics, and corticosteroids. **Symptoms:** * Joint pain and stiffness * Swelling and redness of the joints * Fatigue and weakness * Loss of appetite and weight loss * Fever and chills **Complications:** * Joint deformity and disability * Osteoporosis and bone loss * Eye inflammation and vision loss * Lung disease and respiratory failure * Heart disease and cardiovascular complications ### Significance RA is a significant public health concern, with a substantial impact on quality of life, productivity, and economic burden. The disease is a leading cause of disability and work loss, with estimated annual costs exceeding $100 billion in the United States alone. Despite significant advances in treatment and management, RA remains a challenging condition to manage, with many people experiencing persistent symptoms and complications. **INFOBOX** - **Name:** Rheumatoid Arthritis (RA) - **Type:** Chronic autoimmune disorder - **Date:** 1859 (first described by Alfred Baring Garrod) - **Location:** Global - **Known For:** Chronic inflammation and pain in the joints, leading to stiffness, swelling, and deformity. **TAGS:** Rheumatoid Arthritis, Autoimmune disorder, Chronic disease, Joint inflammation, Pain management, Disease-modifying antirheumatic drugs (DMARDs), Biologics, Corticosteroids, Quality of life, Productivity, Economic burden.
