What is rheumatoid arthritis (RA)?

Rheumatoid arthritis often causes joint pain and swollen

Understand how your rheumatoid arthritis, as well as the effects and side effects of its treatment, will be monitored.

Rheumatoid arthritis (RA) is an autoimmune disease that causes chronic inflammation of the joints. Autoimmune diseases are illnesses that develop when the body's immune system attacks its tissues. The immune system contains a complex organization of cells and antibodies designed normally to "seek and destroy" invaders of the body, particularly infections. People with autoimmune diseases have antibodies and immune cells in their blood that target their body tissues, which can be associated with inflammation. It is not known what triggers the onset of rheumatoid arthritis. Regardless of the exact trigger, the result is an immune system that is geared up to promote inflammation in the joints and occasionally other tissues of the body. Immune cells, called lymphocytes, are activated and chemical messengers (cytokines, such as tumor necrosis factor/TNF, interleukin-1/IL-1, and interleukin-6/IL-6) are expressed in the inflamed areas.

While joint tissue inflammation and inflammatory arthritis are classic RA features, the disease can also cause extra-articular inflammation and injury in other organs.

Because it can affect multiple other organs of the body, RA is known as a systemic illness and is sometimes called rheumatoid disease.

Rheumatoid arthritis that begins in people under 16 years of age is referred to as juvenile idiopathic arthritis or JIA (formerly juvenile rheumatoid arthritis or JRA).

Osteoarthritis is a noninflammatory joint disease whereby the cartilage of the joint thins, typically asymmetrically -- so only one knee or hand may be affected.

What causes rheumatoid arthritis?

Causes of rheumatoid arthritis

Certain factors increase the risk of RA. The common risk factors are as follows: sex, age, family history, obesity, smoking, and environmental exposures to asbestos or silica.

The cause of the autoimmune reaction in rheumatoid arthritis is unknown. Even though infectious agents such as viruses, bacteria, and fungi have long been suspected, none has been proven as the cause. The cause of rheumatoid arthritis is a very active area of worldwide research.

RA symptoms come and go, depending on the degree of tissue inflammation. When body tissues are inflamed, the disease is active. When tissue inflammation subsides, the disease is inactive (in remission).

Remissions can occur spontaneously or with treatment and can last weeks, months, or years. During remissions, symptoms of the disease disappear, and people generally feel well. When the disease becomes active again (relapse), symptoms return. The return of disease activity and symptoms is called a flare.

The course of rheumatoid arthritis varies among affected individuals, and periods of flares and remissions are typical.

What does rheumatoid arthritis feel like?

When the disease is active, RA symptoms and signs can include:

People with active inflammation of joints from RA can also experience:

Muscle and joint stiffness are usually most notable in the morning and after periods of inactivity. This is referred to as morning stiffness and post-sedentary stiffness. Arthritis is common during disease flares. Also, during flares, joints frequently become warm, red, swollen, painful, and tender. This occurs because the lining tissue of the joint (synovium) becomes inflamed, resulting in the production of excessive joint fluid (synovial fluid). The synovium also thickens with inflammation (synovitis).

How serious is rheumatoid arthritis?

Rheumatoid arthritis usually inflames multiple joints and affects both sides of the body. In its most common form, therefore, it is referred to as asymmetric polyarthritis.

Diagnosis of rheumatoid arthritis

There is no singular test for diagnosing rheumatoid arthritis. The diagnosis is based on the clinical presentation.

What are the diagnostic criteria for rheumatoid arthritis?

Understand that many forms of joint disease mimic rheumatoid arthritis.

Is there a genetic marker for rheumatoid arthritis?

Four known genetic markers associated with rheumatoid arthritis (RA) include:

  1. Human leukocyte antigens: The most common and significant genetic mutation associated with RA.
  2. Signal transducer and activator of transcription 4 (STAT4): Responsible for the regulation and activation of the immune system.
  3. Tumor necrosis factor receptor-associated factors (TRAF1/C5): Have a major role in chronic inflammation.
  4. Protein tyrosine phosphatase 22 (PTPN22) genes: Influence the progression and expression of RA.

What specialists treat rheumatoid arthritis?

The primary specialist for diagnosing, managing, and monitoring rheumatoid arthritis is a rheumatologist. The rheumatologist works together with the primary doctor and other specialists to maximize health outcomes and minimize comorbid health conditions.

Other specialists involved in the care of RA patients include the following:

Ancillary health care providers who can be involved in the care of patients with rheumatoid arthritis include physical therapists, occupational therapists, and massage therapists.

What are the four stages of rheumatoid arthritis?

The American College of Rheumatology has developed a system for classifying rheumatoid arthritis that is primarily based on the X-ray appearance of the joints. This system helps medical professionals classify the severity of your rheumatoid arthritis concerning cartilage, ligaments, and bone. The system defines the four stages of RA as follows:

Stage I (early RA)

Stage II (moderate progressive)

Stage III (severe progression)

Stage IV (terminal progression)

Rheumatologists also classify the functional status of people with rheumatoid arthritis as follows:

What are the treatments for rheumatoid arthritis?

What are types of rheumatoid arthritis medications?

Two classes of medicines are used in treating rheumatoid arthritis: fast-acting "first-line drugs" and slow-acting "second-line drugs" (also referred to as disease-modifying antirheumatic drugs or DMARDs).

The degree of the destructiveness of RA varies among affected individuals. Those with less destructive RA or disease that has quieted after many active years can manage their RA with rest plus pain control and anti-inflammatory drugs. Early treatment with second-line drugs (DMARD) improves function and minimizes disability and joint destruction, even within months of the diagnosis. Most people require more aggressive second-line drugs, such as methotrexate, in addition to anti-inflammatory agents. Sometimes these second-line drugs are used in combination.

Non-steroidal anti-inflammatory medications for rheumatoid arthritis

Acetylsalicylate (aspirin), naproxen (Naprosyn), ibuprofen (Advil, Medipren, Motrin), etodolac (Lodine), and diclofenac (Voltaren) are examples of non-steroidal anti-inflammatory drugs (NSAIDs).

Corticosteroid medicines can be given orally or injected directly into joints (intra-articular injections) and tissues. They are more potent than NSAIDs in reducing inflammation and in restoring joint mobility and function.

Second-line (slow-acting) rheumatoid arthritis medications

While "first-line" medicines (NSAIDs and corticosteroids) can relieve joint inflammation and pain, they do not necessarily prevent joint destruction or deformity. Rheumatoid arthritis requires medicines other than NSAIDs and corticosteroids to stop progressive damage to cartilage, bone, and adjacent soft tissues.

Hydroxychloroquine (Plaquenil) is related to quinine and has also been used in the treatment of malaria. It is used over long periods for the treatment of rheumatoid arthritis.

Sulfasalazine (Azulfidine) is an oral medication traditionally used in the treatment of mild to moderately severe inflammatory bowel diseases, such as ulcerative colitis and Crohn's colitis. Azulfidine is used to treat rheumatoid arthritis in combination with anti-inflammatory medicines. Azulfidine is generally well tolerated.

Methotrexate (Rheumatrex, Trexall, Otrexup, Rasuvo) has gained popularity among doctors as an initial second-line drug because of its effectiveness and infrequent side effects.

Gold salts were used to treat rheumatoid arthritis throughout most of the past century. Gold the glucose (Solganal) and gold thiomalate (Myochrysine) are given by injection, initially weekly, for months to years. Oral gold, auranofin (Ridaura), was introduced in the 1980s.

Immunosuppressive medicines are powerful medicines that suppress the body's immune system. Several immunosuppressive drugs are used to treat rheumatoid arthritis. They include methotrexate as described above, azathioprine (Imuran), and cyclophosphamide (Cytoxan). Immunosuppressive medicines can depress bone marrow function and cause anemia, a low white cell count, and low platelet counts. A low white count can increase the risk of infections, while a low platelet count can increase the risk of bleeding. Methotrexate rarely can lead to liver cirrhosis, as described above, and allergic reactions in the lung. Because of potentially serious side effects, immunosuppressive medicines are used in low doses, usually in combination with anti-inflammatory agents.

Leflunomide (Arava) is available to relieve the symptoms and halt the progression of the disease. It seems to work by blocking the action of an important enzyme that has a role in immune activation. Leflunomide can cause liver disease, diarrhea, hair loss, and/or rash in some people. It should not be taken just before or during pregnancy because of possible birth defects and is generally avoided in women who might become pregnant.

Etanercept (Enbrel), infliximab (remicade), and adalimumab (Humira) are examples of biologic drugs that intercept tumor necrosis factor (TNF) in the joints; TNF promotes joint inflammation in RA. These TNF-blockers intercept TNF before it can act on its natural receptor to "switch on" the process of inflammation. This effectively blocks the TNF inflammation messenger from recruiting the cells of inflammation. Symptoms can be significant, and often rapidly, improved in those using these drugs.

Anakinra (Kineret) is another biologic DMARD treatment that is used to treat moderate to severe rheumatoid arthritis. Anakinra works by binding to a cell messenger protein (IL-1, a pro-inflammatory cytokine). Anakinra is injected under the skin daily. Anakinra can be used alone or with other DMARDs.

Rituximab (Rituxan) is an antibody that was first used to treat lymphoma, a cancer of the lymph nodes. Rituximab can be effective in treating autoimmune diseases like RA because it depletes B-cells. These are important cells of inflammation that produce abnormal antibodies that are common in these medical conditions. Rituximab is used to treat moderate to severely active rheumatoid arthritis in patients who have failed treatment with TNF-blocking biologics.

Tofacitinib (Xeljanz) is the first in a newer class of medicines used to treat rheumatoid arthritis called JAK inhibitors. Baricitinib (Olumiant) and upadacitinib (Rinvoq) are also JAK inhibitors. Tofacitinib, baricitinib, and upadacitinib treat adults with moderately to severely active RA in which methotrexate did not work well and who have failed a TNF-blocker biologic.

What is the prognosis for rheumatoid arthritis? Is there a cure for RA?

Rheumatoid arthritis is not a curable disease at this time. As the science of genetics and disease, as well as autoimmunity, evolve, it is very likely that cures for rheumatoid arthritis will become available.

What are the complications of rheumatoid arthritis?

Carpal Tunnel Syndrome

Nerves can become pinched in the wrists to cause carpal tunnel syndrome.

Since rheumatoid arthritis is a systemic disease, its inflammation can affect organs and areas of the body other than the joints.

Is it possible to prevent rheumatoid arthritis?

Currently, there is no specific prevention of rheumatoid arthritis. Because cigarette smoking, exposure to silica minerals, and chronic periodontal disease all increase the risk for rheumatoid arthritis, these conditions should be avoided.

Rheumatoid arthritis diet, exercise, therapy, home remedies, and alternative therapy

There is no special RA diet or diet "cure" for rheumatoid arthritis. However, it is thought that a healthy diet is an important complement to medication in the treatment of rheumatoid arthritis. Research is suggesting that the different kinds of bacteria in our intestines (microbiome) have a big impact on rheumatoid arthritis.

What foods worsen rheumatoid arthritis?

What type of diet is recommended for people with rheumatoid arthritis?

Diets higher in fish, grains, and vegetables decrease the risk of developing RA. The Western diet, defined as including more processed meats, increases the risk. It is not certain whether this is because of a direct anti-inflammatory effect of the fish, grains, and vegetables or because of changes in the natural bacteria in the gut.

Some home remedies may be helpful, although these are not considered as potent or effective as disease-modifying drugs. Fish oils, such as salmon, and omega-3 fatty acids supplements are beneficial in some short-term studies in rheumatoid arthritis. This suggests that there may be benefits to adding more fish to the diet, such as in the popular Mediterranean diet. The anti-inflammatory effects of curcumin in dietary turmeric, an ingredient in curry, may be beneficial in reducing symptoms of rheumatoid arthritis.

Diets and food recommendations for people with rheumatoid arthritis

Supplements for rheumatoid arthritis

Supplements such as calcium and vitamin D prevent osteoporosis in patients with rheumatoid arthritis. Folic acid is used as a supplement to prevent the side effects of methotrexate treatment of rheumatoid arthritis. Alcohol is minimized or avoided in rheumatoid arthritis patients taking methotrexate.

The benefits of cartilage preparations such as glucosamine and chondroitin for rheumatoid arthritis remain unproven. Symptomatic pain relief can often be achieved with oral acetaminophen (Tylenol) or over-the-counter topical preparations, which are rubbed into the skin. Antibiotics, in particular the tetracycline drug minocycline (Minocin), have been tried for rheumatoid arthritis recently in clinical trials. Early results have shown mild to moderate improvement in the symptoms of arthritis. Minocycline has been shown to impede important mediator enzymes of tissue destruction, called metalloproteinases, in the laboratory as well as in humans.

Exercises and home remedies for rheumatoid arthritis

Impact-loading joints can aggravate inflamed, active RA; it's also difficult when joints have been injured in the past by the disease. So, it is important to customize activities and exercise programs according to each individual's capacity. Physical therapy can be helpful. Exercises that are less traumatic for the joints, including yoga and tai chi, can be beneficial in maintaining flexibility and strength. They also lead to an improved general sense of well-being.

Regular exercise is vital in maintaining joint mobility and strengthening the muscles around the joints. Swimming is particularly helpful because it allows exercise with minimal stress on the joints. Physical and occupational therapists are trained to provide specific exercise instructions and can offer splinting supports. For example, wrist and finger splints can help reduce inflammation and maintain joint alignment. Devices such as canes, toilet seat raisers, and jar grippers can assist in the activities of daily living. Heat and cold applications are modalities that can ease symptoms before and after exercise.
