Rheumatoid Arthritis: Symptoms, Causes and Treatment

 

1. Introduction to Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation of the joints. Autoimmune diseases occur when the body tissues are mistakenly attacked by its own immune system. The immune system contains a complex organization of cells and antibodies designed to recognize and destroy harmful substances in the body, such as infectious agents. This leads to the signs and symptoms of rheumatoid arthritis, and the disease can ultimately result in joint destruction and deformity. Rheumatoid arthritis is a chronic inflammatory disease that is also classified as an autoimmune disease. It affects about 1% of the population, and the average onset of the disease is between 40 and 60 years old. It is diagnosed two to three times more often in women than in men. In autoimmune diseases, the body’s immune system produces antibodies against body components as if they were foreign substances. In rheumatoid arthritis, the antibodies are produced against the synovium, which is the membrane that lines the joints. Since the synovium is found in the joint, this is an example of a localized autoimmune disease. The antibodies activate cells to attack the synovium, which gives rise to the disease.

1.1. Definition and Prevalence

Rheumatoid arthritis is a chronic disease that affects the joints, usually in a symmetrical pattern – both sides of the body. It can be incapacitating and painful. Over time, this condition can also affect other parts of the body. The condition is known as an autoimmune disease in which the body mistakenly attacks the healthy joint lining. This leads to the inflammation of the lining and can eventually cause joint deformity and bone erosion. Rheumatoid arthritis can affect people of all ages, although it mostly starts in middle adulthood. Women are more likely to be affected compared to men.

Rheumatoid arthritis produces symptoms that are associated with many other illnesses, resulting in difficulties in diagnosing the condition. The prevalence of this disease has been overestimated in the past due to the inclusion of patients with other similar conditions. However, it is now clear that 0.5%-1% of the population suffers from this disease. In many patients, rheumatoid arthritis can have mild symptoms and physical examination findings. These patients require little medicinal treatment and often suffer few significant long-term health consequences. In other patients, the disease can be more severe, causing joint damage and deformity. These patients require aggressive medical treatment. In a small percentage of patients, sustained inflammation leads to a variety of extra-articular manifestations, which could include an increased risk of cardiovascular disease and lymphoma.

1.2. Understanding the Pathophysiology

Rheumatoid arthritis is an autoimmune disease, which means that the immune system attacks the body's own tissues. In rheumatoid arthritis, the target of the immune attack is the joint synovium, which is the lining of the joint capsule that secretes fluid to lubricate the joint and provide nutrients to the cartilage. Rheumatoid arthritis usually starts in the small joints of the hands and feet and then proceeds to involve other joints in a relatively symmetrical fashion. The disease process destroys cartilage and erodes bone, often resulting in loss of movement and deformity of the affected joints.

Several types of immune cells are involved in the attack on the synovium, including T lymphocytes, B lymphocytes, and macrophages. These cells secrete a number of chemicals called cytokines that stimulate the inflammatory response and cause damage to the joint. There are several cytokines that play a role in rheumatoid arthritis, including tumor necrosis factor, interleukin-1, and interleukin-6. Recent advances in treatment have targeted these cytokines with drugs that inactivate them. However, not all patients respond to these drugs, and research is ongoing to discover other targets for therapy. The destruction of joint cartilage and bone results in the release of proteins into the bloodstream that can be detected and used to diagnose and monitor rheumatoid arthritis. In addition to the joints, rheumatoid arthritis can also affect other organs and systems in the body, including the heart, lungs, and blood vessels.

2. Clinical Presentation

Rheumatoid arthritis can start at any age, with women being affected two to three times more often than men. The disease usually starts in a gradual, subtle way with the slow development of signs and symptoms. The first symptom is frequently pain and stiffness in the small joints of the hands and wrists, although it can begin in any other joint as well. The start of symptoms in more than one joint is one of the features that helps to differentiate early rheumatoid arthritis from other types of arthritis affecting the small joints. The joint symptoms are often worse in the morning and after a period of inactivity, and the pain can be quite severe. Without treatment, joint inflammation can progress over a few weeks to several months and can lead to damage of cartilage and bone underlying the joint. This can result in deformity of the joint and loss of function. Rheumatoid arthritis is a symmetrical disease, meaning that it usually affects the same joint on both sides of the body. Thus, if you have pain, redness, swelling, and other symptoms in one joint, experiencing the same symptoms in the joint on the opposite side of your body is typical. However, asymmetrical joint involvement is also not uncommon, particularly in the early stages of the disease. In addition to the small joints of the hands and wrists, other joints frequently involved in rheumatoid arthritis include the elbows, shoulders, neck, jaw, hips, knees, ankles, and feet. In addition to pain and swelling in the affected joints, rheumatoid arthritis can cause generalized symptoms including weakness, fatigue, low-grade fever, and loss of appetite.

2.1. Symptoms and Signs

Symptoms and signs of rheumatoid arthritis can be divided into two types. First, those caused by inflammation within the joints: warmth, redness, swelling, and pain, usually in small or large joints in a symmetric distribution pattern. Rarely, only large joints are involved. The stiffness is classically worse in the morning and may last for hours. Progression of symptoms over weeks is more characteristic of inflammatory arthritis, in contrast to a mechanical pain pattern that would worsen with increased joint use. Other symptoms are called extra-articular symptoms that do not depend on joint inflammation. These may occur at any time and include fatigue, generalized weakness, low-grade fever, numbness, and tingling. More specific to the disease are rheumatoid nodules, which are flesh-like lumps under the skin. These are usually not painful and occur over pressure points on the body. The lungs, eyes, and mouth can also be affected in some people with rheumatoid arthritis.

3. Causes and Risk Factors

Over 20 million individuals 18 years of age or older in the United States reported having doctor-diagnosed arthritis; among them, over 2 million reported having RA. Females were more likely than males to report being told they had any form of arthritis, including RA. Based on doctor-diagnosed arthritis data, the prevalence of arthritis increases with age, physical inactivity, obesity or overweight, or both being present, and other chronic conditions were reported. As the U.S. population ages, the number of individuals who report having doctor-diagnosed arthritis and the number of individuals reporting symptoms of arthritis—such as pain, joint swelling, or stiffness—are likely to increase significantly. Even though the overall trends in doctor-diagnosed arthritis have been increasing over time for the U.S. population, the number of individuals self-reporting doctor-diagnosed arthritis has decreased in recent years.

While RA is an autoimmune disease, the exact environmental factors that contribute to the development of RA in those with certain genetic markers are unknown. Some researchers suspect that certain bacterial or viral infections in people with a genetic predisposition for RA may trigger the immune system to respond with an inflammatory reaction. The abnormal response leads to the symptoms associated with RA. There is no evidence linking RA to food allergies, such as those to milk, cheese, meat, or eggs, or to food additives or chemicals. Although antibiotics do not cause RA, stressful events, physical and psychological, may cause RA to begin in people with a genetic tendency for it. As nonsteroidal anti-inflammatory agents and analgesics do not prevent the joint damage that occurs in RA, these agents must not be used instead of proper anti-rheumatic treatment. Individuals with RA should eat a healthy, well-balanced diet, modified as needed for any accompanying conditions. RA has few if any direct nutritional implications. Individuals with RA, however, should be familiar with the Food Guide Pyramid so they can get the vitamins, minerals, and other nutrients they need each day.

4. Diagnosis and Tests

The specific details of the tests below are discussed in more detail in a previous section. However, a brief discussion of the steps to diagnosis will be included. The following tests are used either singularly or in combination with one another to assess symptoms and provide evidence of rheumatoid arthritis: blood tests, X-rays, ultrasound, MRI, and synovial fluid aspiration. It has established guidelines for diagnosis and classification that are very useful for physicians. It categorizes patients into one of the following groups: established RA, probable RA, and no RA. The reason for this is that classification is important for clinical trial design and helps in identifying a specific group to study RA in. These tests and criteria have been developed to help the patient and physician in the proper treatment of RA and to avoid unnecessary expensive testing or treatments.

The following lists detail general steps in the diagnosis of rheumatoid arthritis. This is not meant to be a step-by-step process to the diagnosis of RA, but rather a series of changes or steps most patients usually go through in the initial evaluation of their disease. The decision of what test or evaluation to carry out depends on the problems or symptoms a patient has. It is also ​ to remember that the diagnosis of rheumatoid arthritis relies on a number of things including medical history, physical examination, and the results of blood tests and X-rays. The process can take time, and some laboratory tests may have to be repeated specifically for monitoring purposes. In addition, tests and their interpretation may be very different depending on the age, physical condition, overall health, and ethnic background of the patient. Even the sex of a patient is important, as statistically, RA is three times more common in women than in men.

5. Treatment Options

There are many different options for treating rheumatoid arthritis (RA). Each person’s treatment plan will be different, and it is important to work with a doctor and other health professionals to develop a plan that is best for you. The most common type of treatment for RA is medication. There are several different types of medications, and each type works in a different way. Medication for RA can include simple pain relief medication, nonsteroidal anti-inflammatory drugs, corticosteroids, and disease-modifying antirheumatic drugs. Nonsteroidal anti-inflammatory drugs and corticosteroids work to reduce inflammation and to help ease the symptoms of RA. Disease-modifying antirheumatic drugs work to stop the immune system from attacking the joints, in addition to also easing symptoms. Physical therapy is another important part of managing RA. Physical therapy can help to keep joints moving and functioning, manage pain, and daily function. Surgery is not a very common treatment for RA, but it can be an important option for some people. Joint surgery can provide a lot of benefits to people with RA. Early, aggressive treatment of RA helps to slow down joint damage from the disease. Programs work to help people recognize the early signs of RA in themselves, in addition to awareness, to better treatments for people with RA, and work to help people with RA understand the best ways to take care of their health and manage their RA. These programs use different types of information to meet the different needs of people with RA and those who matter to them, such as caregivers.

Conclusion

In conclusion, rheumatoid arthritis is a chronic autoimmune disease that causes joint inflammation and can lead to long-term damage if untreated. While its exact causes are not fully understood, early diagnosis and a personalized treatment plan, including medications and physical therapy, can significantly manage symptoms and slow disease progression. Early intervention is key to improving outcomes and preserving joint function.
