A 37-year-old woman gradually developed painful wrists over 3 months; she consulted her doctor only when the pain and early morning stiffness stopped her from gardening. On examination, both wrists and metacarpophalangeal joints of both hands were swollen and tender but not deformed. There were no nodules or vasculitic lesions. On investigation, she was found to have a raised C-reactive protein (CRP) level (27 mg/l) (NR<10) but a normal haemoglobin and white cell count. A latex test for rheumatoid factor was negative and antinuclear antibodies were not detected.
The clinical diagnosis was early rheumatoid arthritis and she was treated with ibuprofen. Despite some initial symptomatic improvement, the pain, stiffness and swelling of the hands persisted and 1 months later both knees became similarly affected, she was referred to a rheumatologist.
Six months after initial presentation, she developed two subcutaneous nodules on the left elbow; these were small, painless, firm and immobile but not tender. A test for rheumatoid factor was now positive (titer 1/64). X rays of the hands showed bony erosions in the metacarpal heads. She still had raised CRP (43mg/l) but normal serum complement (C3 and C4) levels and she had a biopsy, pannus would have been demonstrable histologically.
This woman now had definite x-ray evidence of rheumatoid arthrotis and in view of the continuing arthropathy, her treatment was changed to weekly low dose methotrexate. This has controlled the arthritis for several years and no further erosions have developed.

Unfamiliar Term
·         C-reactive protein (CRP)
C-reactive protein (CRP) is a protein that can be measured in your blood. It appears in higher amounts when there's swelling (inflammation) somewhere in your body. A C-reactive protein (CRP) test is done to:
o Check for infection after surgery. CRP levels normally rise within 2 to 6 hours of surgery and then go down by the third day after surgery. If CRP levels stay elevated 3 days after surgery, an infection may be present.
o Identify and keep track of infections and diseases that cause inflammation, such as:
Cancer of the lymph nodes (lymphoma).
Diseases of the immune system, such as lupus.
Painful swelling of the blood vessels in the head and neck (giant cell arteritis).
Painful swelling of the tissues that line the joints (rheumatoid arthritis).
Swelling and bleeding of the intestines (inflammatory bowel disease).
Infection of a bone (osteomyelitis).
o Check to see how well treatment is working, such as treatment for cancer or for an infection. CRP levels go up quickly and then become normal quickly if you are responding to treatment measures.
·         latex test
The latex test is a laboratory method to check for certain antibodies or antigens in a variety of bodily fluids including saliva, urine, cerebrospinal fluid, or blood.
·         Rheumatoid Arthritis
Rheumatoid arthritis (RA) is an autoimmune disease where the body's immune system attacks normal joint tissues, causing inflammation of the joint lining. This inflammation of the joint lining (called the synovium) can cause pain, stiffness, swelling, warmth, and redness.

1.      Symptoms of Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic (long-term) disease. Rheumatoid arthritis symptoms can come and go, and each person with RA is affected differently. Some people have long periods of remission. Their rheumatoid arthritis is inactive, and they have few or no symptoms during this time. Other people might have near-constant rheumatoid arthritis symptoms for months at a stretch.
Although rheumatoid arthritis can involve different parts the body, joints are always affected. When the disease acts up, joints become inflamed. Inflammation is the body's natural response to infection or other threats, but in rheumatoid arthritis inflammation occurs inappropriately and for unknown reasons.
Rheumatoid Arthritis and Joint Inflammation
Joint inflammation is a hallmark of rheumatoid arthritis. That includes:
-          Stiffness. The joint is harder to use and might have a limited range of motion. "Morning stiffness" is one of the hallmark symptoms of rheumatoid arthritis. While many people with other forms of arthritis have stiff joints in the morning, it takes people with rheumatoid arthritis more than an hour (sometimes several hours) before their joints feel loose.
-          Swelling. Fluid enters into the joint and it becomes puffy; this also contributes to stiffness.
-       Pain. Inflammation inside a joint makes it sensitive and tender. Prolonged inflammation causes damage that also contributes to pain.
-     Redness and warmth. The joints may be somewhat warmer and more pink or red than neighboring skin.
Which joints does RA affect?
The hands are almost always affected, although literally any joint can be affected with rheumatoid arthritis symptoms: knees, wrists, neck, shoulders, elbows, feet, hips, even the jaw. Joints are usually affected in a symmetrical pattern -- the same joints on both sides of the body.
Rheumatoid Arthritis Symptoms That Affect the Entire Body
Rheumatoid arthritis can affect many areas of the body. These effects all result from the general process of inflammation, leading to a wide variety of symptoms of rheumatoid arthritis:
-   Fatigue
-   Malaise (feeling ill)
-   Loss of appetite, which can lead to weight lose
-   Muscle aches
These feelings have been compared to having the flu, although they are usually less intense and longer lasting. Rheumatoid arthritis may affect other areas of your body. Involvement of multiple areas of the body occurs and is more common with moderate to severe rheumatoid arthritis.
·  Rheumatoid nodules are bumps under the skin that most often appear on the elbows. Sometimes they are painful.
·  Lung involvement, due to either damage to the lungs or inflammation of the lining around the lungs, is common but sometimes causes no symptoms. If shortness of breath develops, it can be treated with drugs that reduce inflammation in the lungs.
·  Rheumatoid arthritis can even affect a joint in your voice box or larynx (cricoarytenoid joint), causing hoarseness.
·  Rheumatoid arthritis can cause inflammation in the lining around the heart, but it usually has no symptoms. If symptoms do develop, it may cause shortness of breath or chest pain. In addition, people with rheumatoid arthritis are more likely to develop clogged arteries in their heart, which can lead to chest pain and heart attack.
·  The eyes are affected in less than 5% of people with rheumatoid arthritis. When the eyes are affected, symptoms can include red, painful eyes or possibly dry eyes.
When you have symptoms of rheumatoid arthritis, early and aggressive treatment can help prevent further symptoms as well as stop progression of rheumatoid arthritis.
2.      The main causes of an elevated C-reactive protein?
In general, the main causes of increased CRP and other markers of inflammation are: burns, trauma, infections, inflammation, active inflammatory arthritis, and certain cancers.
3.      The diagnosis of RA
Diagnosis of rheumatoid arthritis (RA), in the early stages, can be difficult. There is no single test that can clearly identify rheumatoid arthritis. Instead, doctors diagnose rheumatoid arthrit based on the factors strongly associated with this disease. Using American College of Rheumatology criteria list:
1)   The morning stiffness in and around joints a minimum of one hour.
2)   Swelling or fluid around three or more joints simultaneously.
3)   Least one swelling in the wrist, hand, or finger joints.
4)   Arthritis involves the same joints on both sides of the body (symmetric arthritis).
5)   Rheumatoid nodules, bumps on the skin of patients with rheumatoid arthritis. These nodules are usually on pressure points of the body, most often the elbow.
6)   Amount of rheumatoid factor in the blood are abnormal.
7)   X-ray look at the changes in the hands and wrists typical of rheumatoid arthritis, with bone destruction around the joints involved.
4.      Ibuprofen for Rheumatoid arthritis
Information specific to: Ibuprofen 100mg/5ml oral suspension when used in Rheumatoid arthritis.
Ibuprofen (I-bue-proh-fen) is a medicine which is used in a number of conditions - an example is rheumatoid arthritis. The information in this Medicine Guide for ibuprofen varies according to the condition being treated and the particular preparation used.
Your medicine
Ibuprofen helps to reduce inflammation and to reduce pain. Ibuprofen works by blocking the production of some of the body chemicals that cause inflammation, pain, stiffness, tenderness, swelling and increased temperature.
By reducing inflammation in conditions affecting muscles and joints Ibuprofen helps to improve movement.
Other information about Ibuprofen: this medicine will normally be prescribed at the lowest possible dose for the shortest time to reduce the chance of side-effects
Do not share your medicine with other people. It may not be suitable for them and may harm them. The pharmacy label on your medicine tells you how much medicine you should take. It also tells you how often you should take your medicine. This is the dose that you and your prescriber have agreed you should take. You should not change the dose of your medicine unless you are told to do so by your prescriber. If you feel that the medicine is making you unwell or you do not think it is working, then talk to your prescriber.

If at any time it appears that Ibuprofen has become unsuitable, it is important that the prescriber is contacted immediately.
5.      Treatment for Rheumatoid arthritis
The main treatment goals with rheumatoid arthritis are to control inflammation and slow or stop the progression of RA. Treatment is usually a multifaceted program that consists of medications, occupational or physical therapy, and regular exercise. Sometimes, surgery is used to correct joint damage. Early, aggressive treatment is key to good results. And with today’s treatments, joint damage can be slowed or stopped in many cases.
Drugs for Rheumatoid Arthritis
NSAIDs
As part of rheumatoid arthritis treatment, your doctor will probably prescribe a nonsteroidal anti-inflammatory drug (NSAID). These drugs reduce pain and inflammation but do not slow progression of RA. Therefore, people with moderate to severe RA often require additional drugs to prevent further joint damage.
Over-the-counter NSAIDs include ibuprofen (Advil or Motrin) and naproxen sodium (Aleve). Most people with RA require a prescription NSAID as they offer a higher dose with longer lasting results and require fewer doses throughout the day. There are many prescription NSAIDs to choose from.
All prescription NSAIDs carry a warning regarding the increased risk of heart attack and stroke. NSAIDs can also raise blood pressure. In addition, NSAIDs can cause stomach irritation, ulcers, and bleeding.
You and your doctor can weigh the benefits of NSAIDs against the potential risks. You may have to try a few different ones to find the one that’s right for you.
DMARDs
Disease-modifying antirheumatic drugs (DMARDs) help slow or stop progression of RA. The most common DMARD used to treat rheumatoid arthritis is methotrexate. Other DMARDs include Arava, Azulfidine, Cytoxan, Imuran, Neoral, P laquenil, and Xeljanz.
In rheumatoid arthritis, an overactive immune system targets joints and other areas of the body. DMARDs work to suppress the immune system. However, they aren't selective in their targets. Thus, they decrease the immune system overall and increase the likelihood of catching some infections.
DMARDs, particularly methotrexate, have produced dramatic improvements in severe rheumatoid arthritis and can help preserve joint function.
Biologics
The newest and most effective treatments for rheumatoid arthritis are biologics. Biologics are genetically engineered proteins. They are designed to inhibit specific components of the immune system that play a pivotal role in inflammation, a key component in rheumatoid arthritis.
Biologics are usually used when other drugs have failed to stop the inflammation of rheumatoid arthritis. Biologics may slow or even stop RA progression.
TNF blockers help to reduce pain and joint damage by blocking an inflammatory protein called tumor necrosis factor (TNF). For some patients, TNF blockers stop the progression of rheumatoid arthritis. Studies show benefits when TNF blockers are combined with methotrexate. TNF blockers include Enbrel, Humira, Remicade, Cimzia, and Simponi.
Other biologics suppress different areas of the immune system and include Actemra, Kineret, Orencia, and Rituxan.
Since biologics suppress the immune system, they also increase the risk of infection. Severe infections have been reported with biologics.
Steroids
For severe RA or when RA symptoms flare, your doctor may recommend steroids to ease the pain and stiffness of affected joints. In most cases, they can be used temporarily to calm a symptom flare. However, in certain people, steroids are needed long term to control pain and inflammation.
Steroids can be given as injections directly into an inflamed joint or can be taken as a pill. Potential side effects of long-term steroid use include high blood pressure, osteoporosis, and diabetes. But when used appropriately, steroids are often effective and quickly improve pain and inflammation.
