Arthritis (RA)

Rheumatoid arthritis, arthritis (RA) often attacks fingers and wrists in both hands. Pxhere. CC0

Definition

Rheumatoid arthritis (RA) is also called "arthritis". Occasionally confused with arthritis Osteoarthritis ("osteoarthritis"), psoriatic arthritis, gout and rheumatic pain syndroms like Fibromyalgia.

  • Symptoms of Arthritis are Chronic Arthritis (Arthritis) in several joints at the same time (polyarthritis) and one feels sick

The joint swellings are quite soft to feel, usually easy to distinguish from normal joints and from osteoarthritis which has severe thickening. Blood tests show typical changes (see below). Not everyone has strengths joint pain, but stiffness of joints is common, often before the swellings appear.

  • Early diagnosis and treatment are essential to avoid permanent joint damage

Occurrence and causes of illness

About one in 0,5% -1.0% of the population has RA (prevalence), and new cases (incidence) appear to be diminishing (reference: Gabriel SE, 2009)

Climate and arthritis

Climate with changes in temperature, humidity and expression is said to affect the symptoms: "Weather changes, cold and moisture are bad, hot, dry air is good for arthritis"

  • Research has been done that shows increased pain in arthritis when the humidity is high. Studies also show that people with arthritis benefit most from rehabilitation in hot climates. However, changes in temperature and air pressure have not been shown to affect rheumatic pain, and the use of air-conditioned rooms and suitable clothing seems protective anyway. The studies show small results, but do not exclude that some are more affected by climate than others (references: Smedslund G, 2011, Patberg WR, 2004)

Symptoms of arthritis

Without known cause, multiple joints become stiff and sore at the onset of disease. The joints are somewhat hot and swollen (Arthritis) upon examination

  • Typical are persistent, swelling of the wrists, finger joints ("knuckles") and in forefeet (feeling of "walking on cushions")
  • Also knees, ankles, elbows, shoulders, fever and neck are often attacked. The extremities of the fingers (closest to the nails) are not attacked by the thumbs
  • Typically, the same joints on both sides of the body are attacked, but not necessarily at the same time (symmetrical joint manifestations)
  • Many have a "flu" sensation in the body
  • About 7% get "Rheumatic nodes"Later in the process. They are harmless, hard knots beneath the skin, often over the strech side of elbows or fingers
  • Symptoms of rheumatoid arthritis that have been on for more than two weeks should be referred to the rheumatologist
  • In the event of suspicion of rheumatoid arthritis, rheumatological examination should be performed within six weeks of symptom onset

Diagnosis

The diagnosis must be made by a doctor, preferably a specialist in rheumatology

  • General practitioner / physician assesses symptoms, takes current blood tests and refers to the nearest rheumatology department or to a practicing rheumatologist
  • Special examinations of joints to confirm the diagnosis may include examinations with:
    • Ultrasound
    • MRI (magnetic resonance imaging)
    • Radiographs
  • Blood tests are important. Almost everyone has elevated CRP and "erythrocyte sedimentation rate" (ESR). Most also have the more typical anti-CCP (ACPA), and rheumatoid factor (RF) even before the disease breaks out
  • In research, special criteria are used to make arthritis diagnosis
  • When the diagnosis is made, the rheumatologist will register for later comparison:
    • Number of joints that are painful and sore
    • Which joints (and numbers) that are swollen
    • Often, the patient (and doctor) evaluates the disease activity (subjectively) on a scale from 0-10
  • When treating RA, it is important to start early. The treatment effect is then greatest

Complications

Serious joint damage

  • Occurs within a few years if the disease is not adequately treated with appropriate medication

blood

The number of a group of white blood cells (granulocytes) may become too low and the spleen size increases. This may be a sign of Felty's syndrome or LGL syndrome

Depression

Rheumatoid arthritis often results in pain, reduced nighttime sleep, fatigue, rheumatic inflammation / inflammation and reduced physical function. These are the factors they have at their disposal to develop depression. Studies show that about 15% with RA have depression. Early attention to the problem and the implementation of relevant measures is important (reference: Engelbrecht M, 2019)

Heart

"Pericardial fluid" (pericarditis) occurs (reference: Carmona L, 2003)

Lungs

The lungs are attacked at approximately 4 - 10%, usually after several years of disease progression (Reference Kelly C, 2014)

Rheumatoid nodules (nodules)

Revma nodules are harmless hard spheres, most often on the stretch side (extensor) of the elbows and over the fingers. They can also occur in lung tissue

Treatment of arthritis

Treatment of Rheumatoid arthritis (RA) can stop the disease in an early stage.

Treatment av rheumatoid arthritis

Before starting treatment, it is important to be informed about the disease, what the target is, and any side effects that may occur.

  • Treatment goals are to stop the disease completely, that is, obtain remission. Unfortunately, there is no treatment to cure the disease.

Data indicate that the need for hip prostheses was 3 times higher and knee prostheses 14 times higher before more extensive use of disease-reducing treatment (most Methotrexate og Biological drugs) began (1996 versus 2011 in Denmark, Reference Cordtz RL, 2018)

However, adequate physical activity is sensible diet, non-smoking and aids for a simpler everyday life are still important remedies for Rheumatoid Arthritis (Arthritis)

Painkillers

Paracetamol (Paracet, Pinex, Pamol and others) is the first choice because the risk of serious side effects is generally relatively small

  • NSAIDs is an alternative to Paracetamol, but generally at greater risk of side effects
  • Potentially addictive drugs are avoided because long-term treatment and addiction are often needed and other side effects occur in the long term

Cortisone Injections

Swollen joints can be tapped and injected with cortisone which has good effect. Nevertheless, the symptoms will recur after weeks - months (recurring). Cortisone injections are therefore only a supplement to disease-curing treatment.

Cortisone / Prednisolone

Over the first few weeks is Prednisone (cortisone) commonly used, but in quite low doses (15 - 5 mg / day). The effect comes quickly (within a few days). Later the dose is reduced.

  • Some recommend a slightly higher initial dose of prednisolone (15-30mg / day) with gradual termination of termination within six months. It requires initiation of methotrexate (see below) concomitantly with Prednisolone

Methotrexate

To reduce the side effects of cortisone in the long term and to reduce joint damage, supplementation with Methotrexate in the form of tablets one day a week or weekly an injection (Metex) . The dose is often 15-20mg / week. The effect of Methotrexate is felt after 6-8 weeks of treatment.

  • Methotrexate has contributed to people with arthritis now having less aggressive disease and causing less damage to the joints

Other effective drugs

There are a number of other drugs that, like Methotrexate, have effects on both symptoms and the course of the disease

Biological drugs

Medications such as Remicade, Enbrel, Humira, Cimzia, MabThera, RoActemra are often called "Biological". They are designed to block specific parts of the immune system, thereby reducing the activity of the disease. (Reference: Smolen JS, 2015)

JAK inhibitors

JAK inhibitors are a relatively new group of antidepressants in the form of tablets for rheumatoid arthritis. They reduce rheumatic inflammation and the immune system by inhibiting the janus kinase enzymes JAK1, JAK2, JAK3 and to a lesser extent TyK2. This attenuates the interleukins (IL-2, -4, -6, -7, -9, -15, -21) and interferon I and II.

Hormones

Medicines that inhibit the release of ovarian hormones (GnRH antagonists) has shown promising, rapid onset in research studies led by the Norwegian doctor Anita Kåss (reference: Kåss A, 2015). It remains (per 2019) to see if such drugs become available for approved use except in research studies

Other therapeutic measures

Most rheumatology departments work closely with physiotherapists, occupational therapists, social workers and specialty nurses.

  • Physiotherapists can examine joints, muscular strength and physical function. They can set up a plan for individual activity and exercises to maintain mobility and strength
  • Occupational therapists see the need for aids to master everyday life and special tasks in the best possible way when joints and muscles fail.
  • Social workers can, among other things, inform about rights and benefits
  • Nurses with a good knowledge of rheumatic diseases can provide supplementary information, follow up after treatment and be coordinating

Rheumatoid arthritis (RA) and diet

Arthritis (RA) Usually have better medical prognosis / living expectations now than before today's medications were available. Nevertheless, the disease can lead to reduced health. Symptoms are weight loss and fatigue. Blood tests may show low protein (albumin), iron deficiency, vitamins and other trace elements. Protein rich energy drinks, small, but frequent meals (every 2. hour by malnutrition, otherwise every 3-4 hour), and intake of vitamins and minerals are recommended. Meals may consist of fruit, yogurt, oily fish, peanut butter, pasta, egg and chicken. Avoid much sugar. Regular medical checkup with blood tests to measure albumin, iron, folic acid, B12, other vitamins, salts and trace elements is recommended. Measures against osteoporosis is recommended (see above).

Arthritis (RA) contributes to increased risk Atherosclerosis (atherosclerosis) (reference: Dessein PH, 2015). In the process, heart attack and stroke may occur. In arthritis, optimal drug treatment is important, but also risk factors must be reduced as high cholesterol (via diet and drugs), smoking, poorly regulated diabetes (diabetes) and obesity. High intake of multi-unsaturated fatty acids via "Mediterranean diet" reduces the risk of atherosclerosis. Treatment with biological drugs probably has a beneficial effect on atherosclerosis in arthritis (reference: Provan SA, 2015).

A combination of several immunosuppressive drugs (eg Prednisolone, Methotrexate, MabThera, Remicade / Remsima / Inflectra) increases the risk of infection. Avoid foods that may contain bacteria. This can be raw meat, raw fish (sushi), raw eggs, non-pasteurized cheese, milk or unwashed vegetables.

"Difficult RA": When arthritis does not respond to treatment

Despite today's good drugs and other measures, the treatment is still not successful in everyone with RA. This is due to several different reasons listed below. Obviously, each case must be considered separately to achieve the best possible result (Reference: Roodenrijs NMT 2018)

  • Resistance to DMARDs means that the disease modyfying drugs no longer work. Development of antibody by Biological treatment is an possibility.
  • Side effects or intolerance cause few or no good drugs to be relevant
  • Difficulties in taking the drugs
  • Memory problems or reluctance to do the treatment
  • Concomitant other diseases (co-morbidity) that limit the range of drugs that can be used
    • Infections
    • Heart failure
    • Kidney failure
    • Severe lung disease
  • Other conditions that cause persistent rheumatic symptoms despite treatment

Five non-drug measures against rheumatoid arthritis

  1. Quit smoking
    • Smoking is a risk factor for the disease and for a bad prognosis
  2. Ensure good dental status
    • Bad teeth can cause infections that may spread during immunosuppressive treatment
  3. Avoid overweight
    • Obesity can increase inflammation and reduce the effect of biological drugs (see above)
  4. Diet / Diet
  5. Be sure to be vaccinated

Prognosis

Most people have the effect of methotrexate, which is often perceived as the "gold standard" in the treatment. In case of ongoing disease activity, treatment should start immediately after the diagnosis is given, at the latest within 3 months. Nevertheless, many will still have active disease that causes pain and reduces the physical function in the long run. By adding a "biological" drug, most often a TNF inhibitor (such as Remicade, Enbrel, Humira), approximately 70% of patients have better treatment effect. Survival after 5 years with RA is now equal to the rest of the population. Smoking exacerbates the prognosis more by arthritis than expected.

Follow-up of arthritis (RA)

Arthritis needs follow-up and check with a specialist when the disease is in an active phase or the treatment is with special immunosuppressive drugs.

Follow-up by a specialist for rheumatoid arthritis - Arthritis

Regular follow-up of a specialist in rheumatic diseases is internationally recommended for active inflammation, progressive disease or when treatment is given with immunosuppressive drugs (DMARDs or biological drugs).

The role of the specialist is to assess disease activity and signs of side effects. One can not expect patients, GPs and other healthcare professionals to have sufficient competence:

  • If the disease has resolved, it is a specialist task to assess whether the drug doses can be reduced or treatment terminated.
  • The specialist can assess whether the drugs have lost their effect over time
  • Younger patients may want to become pregnant. At the forefront, changes in medication are often required
  • Older people often get other diseases and drugs that affect the anti-rheumatic drugs. Overdose or loss of action is then possible. The specialist is aware of this and may change the treatment
  • When the disease is in a stable phase without special medication, there is no need for follow-up by a specialist
  • Internationally approved recommendations for the follow-up have been prepared and published (EULAR recommendations; Smolen JS 2017)

RA disease develops very differently from person to person and the treatment response is also individual. Nevertheless, the course is generally much milder now than before methotrexate and the newer drugs came on the market. This is shown in the fact that the need for joint operations has been greatly reduced among persons with RA.
