What Are The Causes Of Rheumatoid Arthritis
Our immune system releases antibodies when a foreign material like bacteria and fungus enters the body. Those antibodies fight the foreign material and kill them. However, in some cases, the immune system can mistakenly send antibodies to attack their own cells. This is the root cause of Rheumatoid Arthritis.
List Of Different Types Of Arthritis
Synopsis: General information and list of over 150 various types of arthritis, a form of joint disorder that involves inflammation of one or more joints in humans. The most 5 common types of arthritis are Osteoarthritis, Fibromyalgia, Gout, Rheumatoid Arthritis, and Systemic Lupus Erythematosus. Children and teens get a type of arthritis called juvenile idiopathic arthritis . “Juvenile” means young and “idiopathic” means cause unknown.
Amplification In The Synovium
Once the generalized abnormal immune response has become established which may take several years before any symptoms occur plasma cells derived from B lymphocytes produce rheumatoid factors and ACPA of the IgG and IgM classes in large quantities. These activate macrophages through Fc receptor and complement binding, which is part of the intense inflammation in RA. Binding of an autoreactive antibody to the Fc receptors is mediated through the antibody’s N-glycans, which are altered to promote inflammation in people with RA.
This contributes to local inflammation in a joint, specifically the synovium with edema, vasodilation and entry of activated T-cells, mainly CD4 in microscopically nodular aggregates and CD8 in microscopically diffuse infiltrates. Synovial macrophages and dendritic cells function as antigen-presenting cells by expressing MHC class II molecules, which establishes the immune reaction in the tissue.

Ra Types: What Distinguishes Types Of Rheumatoid Arthritis
The mystery that remains surrounding the direct cause of rheumatoid arthritis makes it difficult to fully categorize the disease. Different symptoms and progression rates turn up in different patients. Though it isnt totally clear what drives these differences, researchers do know that it largely depends on genetics.
Further and further, researchers are finding ways to classify the types and sub-types of rheumatoid arthritis by the actual symptoms patients experience, in addition to other factors. Because of the progressive nature of the disease as well as its tendency to evolve over time, it may be that patients are told they have multiple types or subtypes over the course of their lives.
Further research is being conducted into a deeper classification of rheumatoid arthritis into sub-types that each define unique sets of symptoms and progressions. This will help provide more personalized therapy and medical treatment options.
Who Should Diagnose And Treat Ra
A doctor or a team of doctors who specialize in care of RA patients should diagnose and treat RA. This is especially important because the signs and symptoms of RA are not specific and can look like signs and symptoms of other inflammatory joint diseases. Doctors who specialize in arthritis are called rheumatologists, and they can make the correct diagnosis.

What Are Newer Rheumatoid Arthritis Medications And Side Effects
Newer “second-line” drugs for the treatment of rheumatoid arthritis include the following:
Each of these medicines can increase the risk for infections, and the development of any infections should be reported to the doctor when taking these newer second-line drugs.
While biologic drugs are often combined with DMARDs in the treatment of RA, they are generally not used with other biologics due to the risk of serious infections. Similarly, JAK inhibitor medication is not used with traditional biologic medicines.

Arthritis is a very dangerous disease that affects the body joints. Since the disease gets progressively dangerous with time, it is better for one to have an earlier diagnosis. According to various research studies, arthritic therapies are known to work well when they are started much earlier. The following are some of the types of arthritis that you need to know.

Difference Between Osteoarthritis And Rheumatoid Arthritis
There are several different types of arthritis. Osteoarthritis and rheumatoid arthritis are two of the most common forms. Although the symptoms of these two types of arthritis can be similar, it’s very important to distinguish between them in order to determine the proper treatment.
At the University of Michigan Health System, our experienced rheumatologists will do appropriate tests to determine which type of arthritis you have. Then we will develop an effective treatment plan and will explain your options.
Osteoarthritis occurs when the smooth cartilage joint surface wears out. Osteoarthritis usually begins in an isolated joint.
Rheumatoid arthritis is an autoimmune disease, which means that the immune system malfunctions and attacks the body instead of intruders. In this case, it attacks the synovial membrane that encases and protects the joints. Rheumatoid arthritis often targets several joints at one time. The symptoms of rheumatoid arthritis include:
- the symmetrical nature of the disease ,
Arthritis Prevalence In The Us
Arthritis and other rheumatic conditions are the most common cause of disability among U.S. adults and have been for the past 15 years.
- Nearly 50% of people may develop symptomatic knee OA by age 85 years.
- An estimated 52.5 million adults in the United States reported being told by a doctor that they have some form of arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia.
- 26.0% of women and 19.1% men report doctor-diagnosed arthritis.
- An estimated 27 million adults had osteoarthritis in 2005.
- An estimated 5.0 million adults had fibromyalgia in 2005.
- An estimated 1.5 million adults had rheumatoid arthritis in 2007.

New Symptoms May Change The Diagnosis
Eventually, people with seronegative disease may be diagnosed with a different disease altogether, according to the Arthritis Foundation. If, say, a person diagnosed with seronegative RA develops a skin rash, her diagnosis might change to psoriatic arthritis. Other changes or new test results could lead to a new diagnosis of chronic gout or osteoarthritis. The most important thing at the time you see a rheumatologist is determining whether you have inflammatory arthritis or mechanical arthritis, where there is less that can be done to treat it, says Domingues.
Stage : Antibodies Develop And Swelling Worsens
In many cases, RA progresses to the second stage without being diagnosed. In the second stage the body makes the antibodies and the joints start swelling up, Dr. Bhatt says. It can affect other organ systems and cause inflammation there: the lungs, the eyes, a skin rash, and it can even affect the heart. Lumps on the elbows called rheumatoid nodules may also develop.
When it comes to imaging results, the second stage is more confirmative for the diagnosis, Dr. Bhatt says. It has kind of a moth-eaten, chipped off appearance on the X-rays. Ultrasound can also be done, and the most sensitive is an MRI, which would pick up if there are any problems even if the X-ray is normal.

What If You Dont Respond To The Standard Disease Modifying Drugs
For some people, maybe 10% to 20% of people with RA, the disease is more aggressive and more difficult to get under swift control. But a range of injectablebiologic drugs have revolutionised treatment for people who dont respond to the standard DMARDs. Biologic drugs are a more complex form of DMARD. More recently, another class of drugs called JAK inhibitors have become available which are taken orally in the form of tablets which are as similarly highly effective as biologic drugs.
The NHS follows guidance set out by the National Institute for Health and Care Excellence about when biologics or JAK inhibitors can be prescribed. They are used after standard DMARDs havent worked sufficiently well, so theyre not usually prescribed for people who are newly diagnosed. They are also used if someone does not respond sufficiently well to the first biologic or JAK inhibitor given after standard DMARDs. In many cases, biologic drugs and JAK inhibitors are used with concomitant methotrexate therapy as an anchor drug, as mentioned earlier, as this boosts the overall benefits.
The Presence Or Absence Of Rf Or Acpa Doesnt Make Or Break An Ra Diagnosis
Testing for rheumatoid factor in people suspected of having RA was popularized in the 1960s, and experts still dont fully understand the exact link between these factors and the development of the disease. RF can be positive in multiple diseases, such as hepatitis C, endocarditis, and multiple myeloma.
Rheumatoid factor clearly plays a role in how serious rheumatoid arthritis can be, says John J. Cush, MD, a professor of internal medicine and rheumatology at UT Southwestern Medical Center in Dallas. A different blood test checks for ACPA, which may be more closely linked to the development of the disease than RF. A study published in the journal Autoimmunity Reviews in July 2016 found that ACPA antibodies represent an independent risk factor for developing RA. Having ACPA suggests theres a genetic risk factor for the disease, but its not necessary for either antibody to be present in the blood for a diagnosis of seronegative RA.

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 upon the X-ray appearance of the joints. This system helps medical professionals classify the severity of your rheumatoid arthritis with respect to cartilage, ligaments, and bone. The system defines the four stages of RA as follows:
- No damage was seen on X-rays, although there may be signs of bone thinning
Foods to avoid with RA
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 has a big impact on rheumatoid arthritis. Diet is likely important, but we do not know of specific foods or food groups that should be universally avoided by individuals 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.

What Rheumatoid Arthritis Medications Are In Development
Rheumatoid arthritis treatment is an active area of research. In fact, according to the Pharmaceutical Research and Manufacturers of America, more than 50 drugs for rheumatoid arthritis are in various stages of clinical testing. Many of these are new biologics. Others target histamine receptors and glucocorticoid receptors.

How Is Rheumatoid Arthritis Treated
The goals of rheumatoid arthritis treatment are to:
- Control a patient’s signs and symptoms.
- Prevent joint damage.
- Maintain the patients quality of life and ability to function.
Joint damage generally occurs within the first two years of diagnosis, so it is important to diagnose and treat rheumatoid arthritis in the window of opportunity to prevent long-term consequences.
Treatments for rheumatoid arthritis include medications, rest, exercise, physical therapy/occupational therapy, and surgery to correct damage to the joint.
The type of treatment will depend on several factors, including the person’s age, overall health, medical history, and the severity of the arthritis.
How Is Rheumatoid Arthritis Diagnosed
The diagnosis of rheumatoid arthritis is based on a combination of factors, including:
- Morning stiffness that lasts at least one hour and has been present for at least six weeks
- Swelling of three or more joints for at least six weeks
- Swelling of the wrist, hand, or finger joints for at least six weeks
- Swelling of the same joints on both sides of the body
- Changes in hand x-rays that are hallmarks of rheumatoid arthritis
- Rheumatoid nodules of the skin
- Blood test that is positive for rheumatoid factor* and/or anti-citrullinated peptide/protein antibodies
* The rheumatoid factor may be present in people who do not have rheumatoid arthritis. Other diseases can also cause the rheumatoid factor to be produced in the blood. A test called CCP antibody can sometimes help to determine whether the rheumatoid factor antibody is due to rheumatoid arthritis or some other disease. This is why the diagnosis of rheumatoid arthritis is based on a combination of several factors and NOT just the presence of the rheumatoid factor in the blood.
It is also important to note that not all of these features are present in people with early rheumatoid arthritis, and these problems may be present in some people with other rheumatic conditions.
In some cases, it may be necessary to monitor the condition over time before a definitive diagnosis of rheumatoid arthritis can be made.

What Makes Ra Get Worse
Different factors affect the pace and progression of individual patients RA. Some things you cant control, like whether you have a family history of the disease. In addition, although women are more likely to get RA, when men get rheumatoid arthritis, their prognosis is generally worse, Dr. Bhatt says.
But there are factors you can control and change. We know smoking makes RA more aggressive, so smoking cessation is key, Dr. Lally says. Also, people with heavy manual occupations might stress the joints further and might have quicker progression, Dr. Bhatt says. If your workplace can make accommodations for your disease, that will help. Read more about how to make working with arthritis easier.
Exercise and maintaining a healthy weight can also help reduce stress on the joints, Dr. Bhatt says. But talk to your doctor before starting a workout regimen. A physical therapist can advise patients on the right type of exercise, he says. If patients do exercises wrong it could stress the joints even further. In addition, getting enough sleep, starting an anti-inflammatory diet, eating less red meat, and possibly using herbal remedies like turmeric may help control RA, Dr. Bhatt says. Here are more healthy habits to adopt if you have RA.
Seronegative Ra Could Become Seropositive Down The Road
Your rheumatoid arthritis markers may change over time from negative to positive, since many people with seronegative rheumatoid arthritis begin to develop RF or ACPA antibodies. It happens, but its not that common, says Dr. Domingues. Dr. Cush says people with seronegative rheumatoid arthritis may start to develop RF or ACPA within the first two years of diagnosis.

If your feet are significantly affected, apodiatrist is an essential member of the team. He or she can advise you about looking after your feet and footwear and provide appropriate insoles for your shoes.
Types Of Rheumatoid Arthritis Seropositive Or Seronegative Ra
February 11, 2016 | Blog
Rheumatoid arthritis is an autoimmune disease wherein the immune system attacks parts of the body leading to inflammation of the joints. While the exact cause of RA is still a mystery, it is believed that an infection can confuse the immune system causing it to start attacking the joints. Scientists think that two chemicals in our body, specifically the tumor necrosis factor and interleukin-1 trigger the immune system in rheumatoid arthritis. Symptoms such as pain, stiffness and swelling in multiple joints of the hands, wrists, knees, feet, shoulders, can develop gradually or come on suddenly. RA symptoms are very similar to a number of other diseases, and therefore correct diagnosis even through clinical examination, x-rays, and lab tests can prove difficult. Without early treatment, the disease can damage the fibrous connective joints tissues, which eventually damages the bones.
Rheumatoid Factor Positive RA
Rheumatoid Factor Negative RA
People who test negative for the presence of antibodies or RF in the blood are referred to as seronegative. But they can still have RA. Diagnosis cannot be just based on this test, as clinical symptoms, X-rays, and other laboratory tests will be taken into account. While there is no certainty of this, people who test RF negative are likely to have a milder form of RA than those who test positive.
