The ACR recommends that pharmacologic therapy should be individualized for each patient.  The goals of therapy for patients with RA should be to maintain and/or improve joint function,reduce symptoms including pain,and slow disease progression. Ultimately,helping the patient to achieve full remission is desirable,but few are ever able to do so.
 
NSAIDs are used in RA to reduce joint inflammation and resultant pain and to improve function. The antiinflammatory property of these agents may take several weeks to reach maximal efficacy,while their pain relieving property is more immediate  Patients should be counseled about the importance of taking these agents as prescribed and not combining them with non-prescription agents without the approval of their physicians. NSAIDs cannot alter disease progression but play a important role in symptom relief for patients with RA. For patients with risk of gastrointestinal toxicity from NSAIDs,the prostaglandin analog,misoprostol,or a proton-pump should be added to prevent ulceration. An alternative would be to use the newer COX- -2 inhibitors approved for the treatment of RA.
 
DMARDs should be used for patients,who,despite the use of an adequate trial of NSAIDs,continue to experience pain and swelling in their joints,morning stiffness or fatigue,or elevations in other indicators of inflammation,such as the erythrocyte sedimentation rate or CRP. While they relieve pain and inflammation,NSAIDs cannot prevent the irreversible joint damage that can occur even early in the disease. DMARDs on the other hand,are effective at reducing or preventing joint damage,maintaining and improving joint function, and improving the overll care of the RA patient. These agents should be started during the first 3 months following diagnosis of RA if NSAIDs are ineffective. Currently available DMARDs include methotrexate, gold salts, hydroxychloroquine,sulfasasalazine,D-penicillamine,azathioprine,and a recently released agent leflunomide. Hydroxichloroquine and sulfasalazine are often the first DMARDs used in therapy because of their low side effect profiles. However,it appears that these agents may be less efficacious than some of the other DMARDS,and they often need to be replaced by other agents, dependant  upon the disease severity.
 
Despite the many side effects that may occur with DMARD therapy,current evidence supporting the use of these agents early in therapy to prevent inflammatio,is essential to preserving joint function. Methotrexate has become the most widely prescribed DMARD for RA. It has several side effects that include gastrointestinal problems,rare-liver and pulmonary toxicity and lymphoma. Patients prescribed this agent should be monitored closely for these side effects and educated about ways to monitor themselves for toxicity. Despite these side effects,more patients continue on methotrexate therapy than any other DMARD.
 
DMARDs do not have an immediate onset of action. They may take up to 6 to 10 weeks to see improvements in symptoms,and cocomitant therapy with steriods should be employed during this time. Patients should understand how these agents work and the importance of taking them on a regular basis for maximal benefit. Know when a drug once efficacious has declined in effectiveness. Newer studies are looking at different ways to use these agents,ways to reduce side effects,and to the importance of early intervention. The updated ACR recommendations for RA treatment is that all patients use DMARDs early.
 
Steriods can be used at anytime in the treatment of RA. They are often applied for symtomatic relief of inflammation,but can be combined with DMARD therapy for a more aggressive treatment approach Steriods can be given orally or injected into swollen joints. Long-term administeration of oral steriods has many serious side effects,and may limit their use in treatment. It is important, therefore,that the lowest possible dose to be used for the shortest possible time and remain efficacious. When these agents are prescribed for patients they should be aware of the importance of taking them as prescribed,especially during tapering. Steriods should not be stopped suddenly. Locally injected steriods are unlikely to cause systemic side effects,but the antiinflammatory effect of the injection is often short-lived. The effect can be dramatic and welcome to relieve pain in  a single or few joints when administered.

When selecting a DMARD for the patient, many factors must be taken into consideration, such as time until a benefit is expected, potential for toxicity, and the frequency and potential seriousness of toxicities.
 
Methotrexate (MTX) is often the initial DMARD selected by most rheumatologists. A benefit can be expected 1 to 2 months after initiation of treatment. MTX has a moderate potential for toxicities. Monitoring and controlling adverse reactions are relatively simple. MTX is normally prescribed at a starting dose of 2 to 4 pills per week (5 to 10 mg). The dose can be individualized according to the patient. The starting dose is then increased,up to 6 to 8 pills per week,depending upon the course of the disease. Most patients respond well to MTX,between 50% and 80% achieve effective control of RA. When benefit is incomplete, methotrexate may be given by injection (25 mg). The most common problems with methotrexate are nausea, heartburn,inflammation in the mouth,and hair loss. Normally,the side effects can be reversed,either by decreasing the dose,if the disease is under control,or by adding a vitamin pill containing folic or folinic acid,12 to 18 hours after the MTX dose Most physicians add 5 mg of folic acid 5 days a week,to the methotrexate regimen from the beginning. Most serious,but uncommon problems with MTX include inflammation and scarring in the liver or the lungs. Most patients who develop liver problems have underlying medical conditions that make them susceptible to the side effects: diabetes,alcoholism,liver, hepatitis or obesity.
 
Hydroxychloroquine (HCQ) treatment results in a benefit that is detectable 2 to 6 months after initiation of treatment. Its potential for toxicity is relatively low and patients should be monitored for retinal toxicity. A yearly eye examination is desirable. The dose of HCQ (Plaquenil) is one or two pills (200 mg) taken at bedtime. Patients may experience nausea,but other side effects is relatively uncommon. Plaquenil is an inexpensive,safe,easily monitored DMARD that works well in early and mild RA
 
Leflunomide (LEF) is the newest traditional DMARD, with benefits seen 4 to 12 weeks after treatment begins. A loading dose of 100 mg daily for 3 days and then 25 mg daily is a frequently used routine to follow. It also has a relatively low potential for toxicity. Patients should be monitored for diarrhea, alopecia, rash, headache, and risk of immunosuppression infection. LEF is a useful drug for patients that cannot tolerate MTX or when MTX alone,is subpar,it can be used in combination. Most physicians will rate LEF somewhat on par with SSZ and perhaps less efficacious then MTX when used alone.
 
Sulfasalazine (SSZ) results in treatment benefits 1 to 3 months after the drug is initiated. It also has a low potential for toxicity, of which myelosuppression, nausea, gastrointestinal pain,malaise,dizziness,and headache is common. However,allergic skin rashes and a decrease in all blood cells do occur in some patients. Most side effects occur during the first 3 months of therapy. SSZ is usually taken as a daily dose of 2 to 3 grams. Ideally,the dose is increased s;owly: 500 mg daily diring week 1; 1000 mg daily during week 2; 1500 mg. daily during week 3; and 2 grams daily during week 4. Blood tests should be scheduled for the first 3 months,then every 3 months. SSZ may interact with other drugs. A review with your physician is warranted. Its initial beneficial effects may decrease more rapidly then other DMARDs.
 
Patients can expect a benefit 4 to 8 weeks after beginning treatment with cyclosporine. The drug has a high potential for toxicity and is associated with renal insufficiency, anemia, and hypertension. It is used primarily for patients with refractory disease (when other therapies have failed).
 
Treatment with oral or parenteral gold also results in benefits from 3 or 4 months to 6 months after treatment initiation. The potential for toxicity for oral gold is low, while that for parenteral gold is moderate. Toxicities to monitor include myelosuppression and proteinuria. Approximately 30% of patients taking gold experience side effects. Most side effects are mild and common; they include an itchy skin rash,protein in the urine and inflammation of the mouth. A more severe side effect is kidney damage (nephrotic syndrome),seen in 5 % of patients. This can occur within the first 6 months of treatment. The most serious side effect of gold is suppression of the bone marrow,probably due to hypersensitivity reaction. this marrow suppression can result in a decreased number of blood clotting cells,or platelets (thrombocytopenia),a decreased number of white cells (neutropenia),or an absence of all types of cells (bone marrow failure,or aplasia). Bone marrow suppression is the most serious and feared side effect of gold treatment,it is the main reason it is not prescribed frequently,as MTX.
 
Patients treated with azathioprine can expect a benefit 2 to 3 months later. The potential for toxicity is moderate with this drug, and rheumatologists should monitor patients for myelosuppression, hepatotoxicity, and lymphoproliferative disorders. It is getting a recent revival,when used in combination with MTX.
 
Minocycline is a tetracycline that results in a treatment benefit within 1 to 3 months of treatment. Its potential for toxicity is low. Toxicities include hyperpigmentation, dizziness, and vaginal yeast infections. It is employed in the milder type of disease.
 
The results of some recent monotherapy trials with the traditional DMARDs MTX, SSZ, and LEF:
 
In patients with early RA (median disease duration of approximately 1 year), ACR20 response rates achieved with MTX (7.5 mg to 20 mg/wk) ranged from 59% to 65%. The Dougados study reported that 38% of patients were European League Against Rheumatism (EULAR) "good" responders; ACR50 response rates were achieved by 42% of patients in the second early RA study, conducted by Bathon and colleagues.
 
The efficacy of MTX is decreased in those patients with a longer disease duration (median, 6 years) in the study by Strand and colleagues. In this study, 35% of patients achieved ACR20 and 23% achieved ACR50 criteria.
 
In monotherapy trials of SSZ at a dose of 2 to 3 g/d, 59% of patients with early RA (median disease duration of 1 year) achieved an ACR20 response; 34% of patients were EULAR "good" responders. Response rates were somewhat reduced in patients who had RA for a median of 7 years; 44% of patients achieved ACR20 and 30% achieved ACR50 criteria.
 
Two recent studies evaluated the efficacy of LEF 20 mg/d in patients who had RA for 7 to 8 years. ACR20 response rates were 41% and 48%, while ACR50 response rates were 33% to 34% in these studies.
 
O'Dell and colleagues evaluated the efficacy of triple-drug combination therapy with traditional DMARDs for the treatment of patients with RA. They compared the efficacy of combination therapy with MTX (up to 17.5 mg/week) and HCQ (200 mg bid), MTX and SSZ (up to 1 g bid), and all three drugs in 171 RA patients who had not previously been treated with combinations of the study medications in a 2-year, double-blind, placebo-controlled trial.
 
The primary end point was the percentage of patients who had a 20% response to therapy according to the ACR20 criteria at 2 years.
 
Intent-to-treat analysis revealed that patients receiving the triple combination responded best, with 78% achieving an ACR20 response at 2 years, compared with 60% of those treated with MTX and  HCQ (p = 0.05) and 49% of those treated with MTX and SSZ (p = 0.002).
 
Similar trends were seen for the ACR50 response, with 55%, 40%, and 29% of patients in the three treatment groups, respectively, achieving these results at 2 years (p < 0.10 for the triple combination group versus MTX and HCQ and p = 0.005 versus the MTX and SSZ group). The respective values for ACR70 were 26%, 16%, and 18%.
 
The triple combination of MTX, SSZ, and HCQ is superior to the double combination of MTX and SSZ and marginally superior to that of the double combination of MTX and HCQ.
 
In the COBRA trial (Combinatietherapie Bij Reumatoide Artritis), Boers and colleagues demonstrated the effectiveness of a step-down approach for suppressing disease in patients with RA. These investigators assessed the value of intensive combination therapy in early RA in a multicenter, double-blind, randomized trial (COBRA).
 
They compared the combination of SSZ (2000 mg/d), MTX (7.5 mg/week), and prednisone (initially 60 mg/d, tapered in 6 weekly steps to 7.5 mg/d) with SSZ alone in 155 patients with early RA.
 
The main outcomes were the pooled index (a weighted change score of five disease activity measures) and the Sharp/van der Heijde radiographic damage score in hands and feet.
 
At week 28, the mean pooled index was 1.4 in the combined treatment group and 0.8 in the SSZ group (p < 0.0001); 55 patients (72%) and 39 patients (49%), respectively, were improved according to ACR criteria.  The clinical difference between the groups decreased and was no longer significant after prednisone was stopped, and there were no further changes after MTX was stopped.  At 28 weeks, the radiographic damage score had increased by a median of one in the combined therapy group and by four in the SSZ group
(p < 0.0001).  These investigators concluded that combined therapy immediately suppressed damage progression, whereas SSZ alone was less effective.
 
While traditional DMARDs are able to modify disease progression, the long-term effectiveness of these drugs may be less than optimal.  A recent observational study that examined the long-term discontinuation rates of traditional DMARDs in 1,132 patients who received 2,296 DMARDs found that 54% of the DMARD regimens had been discontinued.
 
The median time patients were on traditional DMARD therapy prior to discontinuation varied from 9 months for oral gold to 33 months for MTX. The most common reason for discontinuation was lack of efficacy, a cause for 25% of patients. Drug toxicity, cited by 20% of patients, was the second most common reason for discontinuation of therapy.
 
Among the different traditional DMARDs, discontinuation rates varied from 34% for MTX to 70% for oral gold. A higher percentage of patients on oral gold and SSZ discontinued as a result of lack of efficacy; discontinuation because of toxicity occurred with highest frequency (34%) among those patients taking D-penicillamine.

A longitudinal treatment plan needs to be developed with the patient. The discussion should address disease prognosis and treatment options, taking into account the costs,adverse effects,expected time for response, and monitoring requirements of pharmacologic agents,in addition to the patient's preferences.
 
Expectations for treatment and potential barriers to carrying out the recommendations should be discussed. Patient education is critical to engaging the patient in an effective partnership for managing the disease The aggressiveness and timing of the treatment program require an assessment of prognosis. Poor prognosis is suggested by earlier age of onset,high titer of RF,elevated ESR,and swelling of  >20 joints.
 
Extra-articular manifestations of RA,including rheumatoid nodules, Sjogren's syndrome,episcleritis and scleritis, intestitial lung disease, systemic vasculitis,and Felty's syndrome,indicate a worse prognosis. These manifestations may vary in severity and significance.
 
Even if inflammation is successfully controlled or eliminated with medication, patients with chronic RA may be symptomatic from joint damage. If,in spite of optimal medical treatment,the patient has unacceptable pain and/or limitation of function because of structural damage,surgery should be considered. Surgery is not for everyone, however, and the decision should be made after careful consideration by patient and doctor:
 
Joint replacement-- This is the most frequently performed surgery for RA,and it is done primarily to relieve pain and improve or preserve joint function. Artificial joints are not always permanent and may eventually have to be replaced.This may be a issue for younger people. Upgrade and research into superior longer-lasting implants is on-going.
  
Tendon recontruction: RA can damage and even rupture tendons,the tissues that attach muscle to bone.This surgery,which is used most frequently on the hands,reconstructs the damaged tendon by attaching an intact tendon to it.This procedure can help to restore function, especially  if the tendon is completely ruptured.
 
Synovectomy: in this surgery,the doctor actually removes the inflamed synovial tissue. Synovectomy by itself is seldom performed now because not all of the tissue can be removed,and it grows back Synovectomy is done as part of reconstructive surgery,especially tendon reconstruction.
 
Essential component of management include: 1) Establishment of the diagnosis of RA (versus other forms of polyarthritis). 2) Systemic and regular evaluation of disease activity. (monitoring)  3) Patient education/rehabilitation interventions and initial treatment with NSAIDs. 4) Use of DMARDs.(early)5) Possible use of local or low-dose oral glucocorticoids. 6) Minimization of the impact on the individuals's function. 7) Assessment of the adequacy of the treatment program and general health maintenance.
 
The course of rheumatoid arthritis cannot be predicted in a given patient. Several patterns have been described *A spontaneous remission particularily in the seronegative patient (mild RA) within the first 24 months of symptoms (less than 10%). *Recurrent explosive attacks followed by periods of quiescence,most commonly in the early phases. *The usual pattern of persistant and progressive disease that wanes and waxes in intensity. *There is mild-prominent stiffness-moderate-severe RA patients. *Some patients will have extra-articular features associated with the disease that can affect the whole body. *The pattern of disease activity,severity and disease progression will be individualized in most patients -this also applies to medication and therapy.
 
Disability is higher among patients with RAwith 60 % being unable to work 10 years after the onset of disease. Recent studies have demonstrated an increased mortality in rheumatoid arthritis patients. Median life expectancy was shortened an average of 7 years for men and 3 years for women compared to controlled populations in more than 5000 patients with RA from four centres.
 
The mortality rate was two times greater than in the control population. Patients at risk for shortened survival are those with with systemic extra-articular involvement,low functional capacity,low social-economic status,low education and predisone use,according to the study.
 
Rheumatoid arthritis usually starts gradually,but it can start suddenly in some. You might feel tired and achy,like you have the flu. Most people feel pain and stiffness in one or more joints,usually the hands, wrists, or feet. The joints may not be swollen at the beginning but will probably start to swell within a couple of months.
 
The joints pain almost always occurs in symmetrical joints,i.e.,the same joints on both sides of the body. E.G.,you might feel pain in both wrists or in the same finger on both hands. This is the usual case. Some people do not het joint pain right away,they just feel stiff all over,especially when they get up in the morning. The stiffness usually lasts 1 hour or more,others say the stiffness never goes away.
 
Other patients feel achy and stiff, particularily in the hips and shoulders,and this may continue for weeks or months before the joints start to swell-feel warm (inflammation ). This course occurs more in older patients and may be confused with a disease called polymyalgia rheumatica.
 
Other people have swollen joints that are not painful at onset. There is much variation in the symptoms of rheumatoid arthritis and that also applies to patient efficacy of medication. One drug will work wonders for one patient and do nothing for another.
 
Side effects follow a similiar pattern in some  patients. However,a symmetric painful series of joints particularily in the hands,feet,and wrists is the most common presentation of this disease.
 
In some people,the joints are painful and swollen,then they get better,then worse again. RA can also,but very rarely,be asymmetric,i.e.,it can occur in a joint on one side of the body but not in the other side corresponding joint on the other side. Eventually,even in these people,the joints on the other side is also affected.-the disease becomes symmetric,the typical course of rheumatoid arthritis.
 
It was traditionally taught that 70-80% of RA patients could be controlled with NSAIDs alone. These NSAIDs were given on the false premise that most people with time will go into remission. Second-line drugs were considered "highly toxic" and were reserved for those patients who could not be controlled by the first-line drugs. It is now,well established,that spontaneous remission are not common and that early treatment with DMARDs is essential.
 
The importance of treating RA early cannot be overemphasized. There is a window of opportunity for good control of the disease and prevention of joint damage early in the course of the illness. Irreversible erosion can be seen on x-ray films within the first 1-2 years after the onset of the disease,and even earlier using magnetic resonance  imaging. Delays in treatment as short as 8-9 months nd shorter-have been associated with significantly damage and disability at 3 years and 5 years of follow-up.
 
Current recommendations include starting DMARD therapy as soon as the diagnosis of RA has been established. This means after 6 weeks of inflammation despite treatment with anti-inflammatory drugs. The aim of therapy is no longer simply to control the symptoms at a level of comfort that is satisfactory to the patient but also to eradicate inflammation,and thus have a greater impact on the associated disability. 
 
More aggressive therapy means continuous use of DMARDs, increasing the doseage to maximum tolerated or recommended until miminal or no inflammation is achieved, switching to a different DMARD if no benefit is obtained after a trial at the maximum dose for an appropriate duration,and using combination therapy. Although DMARDs are potentially toxic,their skillful use by a experienced clinician can help prevent problems. The incidence of serious side effects in long-term studies is rare.
 
Consultation with a rheumatologist is desirable before initiating DMARD treatment. It is important to have a definite diagnosis of RA before beginning DMARD therapy to avoid exposing patients to the risk of serious side effects for a benign transient arthritis.
 
The trend toward earlier and more aggressive treatment is not limited to RA. It has also shown to affect the prognosis of other rheumatic diseases,such as lupus nephritis, polymyositis, dermatomyositis and vasculitides.
 
Exercise helps lessen the symptoms of RA and can make you feel better overall. Appropriate and moderate stretching and strengthening will help relieve the pain,and keep the muscles,and tendons around the affected joint flexibile,and strong. Low impact exercises like swimming, walking,water aerobics,and perhaps stationary bicycling (if the knee is affected consult your doctor) can all reduce pain while maintaining strength, flexibility,and cardiovascular function
 
Physical therapists (preferably trained in rheumatic disease treatment) can teach you other techniques to manage the pain,and restore joint motion,and muscle strength. With the aid of properly trained occupational  therapists,they can assist the patient  in maintaining optimal function at work,in the home,and during leisure activities. There are also nurses specifically trained in rheumatic diseases.
 
Patients may be referred to physiotheraphy and occupational therapy for treatments such as icing,the applying of wax and ultrasonography to reduce the symptom of inflammation. They may be referred to the Arthritis Self-Management Program.or other educational programs, offered by the Arthritis Society of Canada (http://www.arthritis.ca/) and others,to help them understand their disease and,thus,improve their ability to cope with symptoms. Patients must be made aware of the need for monitoring. The incidence of serious side effects is markedly reduced with regular monitoring,because adverse effects are more likely  to be discovered before serious serious or irreversible consequences arise.
 
Despite the long list of side effects which intimidates patients,long-term series of RA patients treated with DMARDs have found that serious side effects are rare.
 
When counselling a patient who express concern about potential side effects,it is also important to remind him or her of the consequences of the alternative, doing nothing will result in irreversible disability,progressive joint damage and premature death. Drugs such as methotrexate and cyclosporine, which are used in cancer therapy and transplant therapy respectively,are used in lower doses for RA.and the incidense of adverse side effects is lower. Persistence in the use of DMARD is of great importance.
 
DMARDs are used to treat incurable chronic diseases when treatment will be lifelong and the number of options is limited. Typically a patient with RA will use a succession of DMARDs over the years. After an initial response,a drug is often eventually discontinued,either because of adverse side effects or loss of effect.
 
To ensure the best result,it is important to give each drug a full trial, namely,the maximum dose for sufficient time,before declaring a drug is not efficacious. There are a number of strategies for dealing with common side effects.
 
The use of combination DMARDs is now widely practised,Some physicians advocate the use of combination therapy at the onset of disease early control,with a subsequent gradual withdrawal of therapy,as necessary to maintain control. Others prefer the opposite strategy successively adding DMARDs to agents to which the patient has shown a partial response. Proponents of the latter view,believe it prevents unnecessary exposure to potentially toxic drugs of patients who may respond to single therapy
 
Commonly used combinations include hydroxychloroquine with most DMARDs,especially methotrexate,or intramuscular gold,sulfasalazine and methotrexate with or without hydroxychloroquine,and cyclosporine and methotrexate.
 
The most accurate and most often used measurement of inflammation is the sedimintation rate or "sed rate".This test is based on how quickly  red blood cells settle at the bottom of the test tube.The ESR is useful in differentiating RA from other types of arthritis. If your joints are very swollen your doctor may take a small sample from the swollen joint.Normal synovial fluid is clear,thick and oily,it becomes cloudy because it is infiltered with usually white blood cells and debris
 
Baseline laboratory evaluations should include complete blood count (CBC), platelet count,chemistery profile,RF measurement,and measurement of ESR or CRP. Evaluation of renal and hepatic function is necessary since many antirheumatic agents have renal or hepatic toxicity and may be contraindicated if these organs are impaired.
 
There's a wide variety of topical creams and gels available that provide temporarily pain relief-including a prescription cream made from the active ingredient (capsaicin) in hot chili peppers. Some creams contain the active ingrediant (acrtylsalicylic acid) in ASA,which is absorbed through your skin and should be factored into your total daily dose if you're taking ASA or ibuprofen in tablet form. Since it's difficult to calculate how much ASA you've absorbed into a cream,try to avoid using a cream and tablets on the same day. And keep in mind that all such creams are for pain relief only,they aren't effective as NSAIDs.
 
The majority of creams and gels (and liniments and poulticies)are counter irritants,which work by pitting one pain against another, inducing the body to lower its sensitivity. Applied to a painful joint,they produce a temporary local reaction that may cause skin irritation,mild swelling or a temperature change-and a lessening of pain.Most such counterirritants use heat or cold to'distract' the brain from recognizing the signal from the pain source by amplifying the nerve signals recieved by your brain's pain centres. Overwelmed by the influx of chemical messages,the brain temporarily'switches' them off,thus providing pain relief.
 
According to a 1995 ,November issue of Letters,at the University of Berkeley,clinical studies into capsaicin's use have been small and short-term,and not much is known about the effect of long-term use. Still,they note that many people find capsaicin helps. 'As the package direction should say,you need to use the cream 3 or 4 times a day,and you may not notice much improvement until you've applied the cream for a week or more. Many people can't tolerate it-skin becomes irritated. Never use the cream under a bandage,and don't get it into your eyes. or an open cut.
 
For some people,rubbing one of these salves on a arthritic joint is as effective as the pain relief they experience from NSAIDs. Capsaicin,the alkaloid that gives chili peppers their fire,has been recruited as a counterirritant. Nonprescription salves or lotions,such as Zostrix,Capzasin-P and Capsin contains 0.025 to 0.25 % capsaicin, through a tube of cream may contain as much pure capsaicin as hundreds of chili peppers. While such creams generate a feeling of warmth on the skin,their effect is muted enough that you can apply the treatment several times a day.
 
Some promising combinations include: 1) Methotrexate (MTX) and Sulfasalazine (SSZ) and Hydroxychloroquine.(HCQ) 2) MTX and Intramuscular Gold .3) MTX and Etanercept. (Enbrel )4) MTX and Leflunomide ( Arava )5) MTX and Infliximab. ( Remicade )6) MTX and Cyclosporin has been tried ,but due to higher toxicity of cyclosporin it is not used commonly,today.
 
7) MTX and Arava ( Leflunomide ) might not work for everyone. Monitoring and selection will  vary due to differences in patient efficacy.
 
Methotrexate has become the gold standard in North America. It promises early onset of action,usually within 4 to 6 weeks. MTX is usually given as tablets,but can be given subcutaneously.
 
The effective weekly dose for a patient may be low as two 2.5 mg tablets,or as high as ten. The average is 5 tablets (12.5mg.) once a week. Because the effective dose range is so wide,its best to start low (3 tablets / week). and only slowly increase the dose by one tablet each time. changes in dose should occur no more often than every 3 weeks;once a month is the usual.
 
It is unusual to notice a good response at a fairly low dose at first,but then to require a higher dose later on to maintain that response. A complete blood count (hemoglobin,white cell and platelet counts ) is usually done every 2 weeks until the final dose is selected,then every 4 to 6 weeks Liver function test may be performed,depending on the patient situation. Some patients claim better response with the injection procedure with less side effects.
 
NSAIDs don't interact with MTX when MTX is taken in the doses recommmended; however,sulfa-containing antibiotics increase the risk of side effects and should be avoided. Side effects are ofen dealt with by decreasing the dose or temporarily stopping MTX and then restarting it.
 
Gold has the potential of disease suppression.,but it is more toxic The regular dose is (50 mg./weekly). To make sure the patient isn't sensitive to gold,two small test doses of aurothiomalate are given,one week apart. The practise in the past was to do this,once a week,until 1,000 mg. had been given,and some doctors may still do this. If the patient is no better,then they try another drug
 
The major disadavantage include the need to visit the doctor each week,the longer time for efficacy (12 to 20 weeks), Blood tests and urine tests are usually done prior to injection. Twenty weeks is a long time to wait to see if the drug works or not. If it does not work,it is valuable "wasted time" w.r.t. to the ongoing disease process.
 
Azathioprine is taken daily. The initial dose is one tablet (50 mg) and later the dose is adjusted according to the patient's weight. Later,if the patient has done well,the dose can be reduced without losing the effect. Once a regular dose has been settled on complete blood counts (CBC) are needed less frequently than with mtx and gold,but it should still be checked at least every 3 months.
 
Sulfazaline is used more in Europe. The British rank it somewhere near intramuscular gold. Its safety profile is excellent. It takes action in 2 to 3 months
 
There are some conflicting reports as to whether SSZ is useful in some of the seronegative arthritis cases, PA and AS. SSZ should be started with a low dose and gradually built up. Start with one tablet (500 mg) a day for a week,then increase the daily dose by one tablet each week until, by the fourth week the patient is taking two tablets twice a day, there are other variations to this schedule.
 
Hydroxychloroquine HCQ) is considered to be much weaker than almost all the other DMARDs(plaquenil). It's safety profile is excellent It takes effect in 3 to 6 months ,but its long-term benifit is not so good as the others. In the case of severe RA,six months is a long time to wait,and find the drug ineffective.
 
It's very important to get a annual eye check up. The maximum daily dose is 400 mg-calculated w.r.t. bodyweight--200 mg/twice/daily.
 
Auranofin-oral gold has been proven to be a disappointment. There is little flexibility in the dose of auranofin- one 3 mg. tablet twice a day. A complete CBC and urinalysis /monthly.
 
D-penicillamine and cyclosporin is not commonly used today. With the many alternative,including the newer biologics the two are on the "back-burner" but when every thing else fails, they are available-they have higher toxicity levels,and hard to control,at times
 
The development of genetically engineered biologic agents that selectively block cytokines (anticytokine therapy) in the short term,represents a major advance in the treatment of RA. Etanercept is a recombinant soluable TNF-fc fusion protein,and infliximab is a chimeric (mouse-human ) anti-TNF monoclono antibody.
 
Infliximab is currently recommended for use only with concomitant MTX therapy. MTX may be used with etanercept or used alone. Several randomized trials have demonstrated that patients with etanercept alone or with infliximab plus MTX have less radiographic progression after 1 year rhan patients treated with MTX alone. In the trial with patients made up of early RA patients,the symptoms and signs of RA improved more rapidly over the first 6 months,with compare able efficacy of the two agents at 12 months.
 
The ACR guidlines for monitoring liver toxicity in patients recieving MTX is that a liver biopsy should be performed in patients who develop abnormal findindings on liver function studies,that persist during treatment or upon discontinuing the drug. Liver toxicity with MTX is rare.
 
Although data from randomized trials have not shown an increased frequency of adverse effects,such as infections or malignancies,for either anti-TNF agent,concerns about the short-term and long-term safety of these agents continue. Enbrel was recently given a 5 year safety approval in clinical trials.
 
Clinical trials have demonstrated the efficacy of infliximab and etanercept in improving clinical symptoms and signs in patients with RA,according to the ACR 20, 50, and ACR 70 improvement criteria. Patients with early active RA and those that had failed previous conventional therapy showed improvements. Anti-TNF agents should be used with caution in patients susceptible to infection or a history of T.B.,should be avoided in patients with significant chronic infections and should be discontinued,temporarily in all patients with acute infection
 
Postmarketing surveillance has yielded reports of septis,tuberculosis.a typical mycobacterial infections,but it not common. At this time there appears to be no need of routine laboratory testing. Not all patients will respond to TNF therapy. The main disadavantage is high cost and parental administration.
 
Conventional treatment with a single DMARD often fails to adequately control clinical symptoms or to prevent disease progression. As a result rheumatologists are increasingly prescribing combination DMARD therapy. Controversy remains whether to initiate this type of therapy in a sequential "step-up" approach in patients with persistent active disease in whom single agents have failed or whether to initiate combination therapy early in the disease course and then apply a "step-down" approach once adequate disease control is attained. In either case rheumatology referrel is strongly recommended,when considering this route.
 
Since DMARDs control rather then cure RA,the management of RA is an iterative process and patients should be periodically reassessed for evidence of disease or limitation of function with significant alteration of joint anatomy. Reconstructive surgery can be done at any point in the course of RA.
 
Some patients have resistant disease and experience a progressive course despite exhaustive trials of DMARDs, whether used alone or in combination. At each followup visit the physician must asess whether the disease is active or inactive. Symptoms of inflammatory (as contrasted with mechanical ) joint disease,which includes prolonged morning stiffness,duration of fatigue,and active joint synovitis on joint examination,indicate active disease and necessitate consideration of changing the treatment regimen
 
Occassionally,findings of the joint examinations alone may not adequately reflect disease activity and structural damage.therefore,periodic measurements of the ESR and CRP level and functional status as well as radiographic examinations of involved joints should be performed.
 
Functional status may be determined by questionnaires such as the Arhtritis Impact Measurement Scales or the Health Assessment Questionnaire. It is important to determine whether a decline in function is the result of inflammation,mechanical damage or both,treatment strategies will differ,accordingly.
 
The American College of Rheumatology (ACR) has developed criterias for defining improvement and clinical remission in RA. These criteria is accepted world-wide in rheumatology circles.
 
People living with RA will need to become more familiar with the treatment regimen,know when therapy is working and when it is not. Familiarize themselves with side effects so that when they occur,intelligently inform their physicians as to change of dose or medication to ensure safety,health,and success of the whole treatment and managment process.
 
Instruction in joint protection,conservation of energy,and a home program of joint range of motion and strengthenining exercises are important in achieving the treatment goal of maintaining joint function. Occupational therapy and physical therapy may help the patient who is compromised in activities of daily living.
 
Regular participation in dynamic and even aerobic conditioning programs improves joint mobility,muscle strength,aerobic fitness and function and psychological well being without increasing fatigue or joint symptoms.
 
Given the chronic waxing and waning course of RA,a longitudal treatment plan needs to be developed and the patient should be involved in the treatment plan The discussion should include disease progression,prognosis and treatment options,taking into account the cost,adverse risk factors and comorbid conditions monitoring disease activity (i.e., ongoing disease activity after 3 months of maximum therapy ),or progressive joint damage require consideration of significant changes in the DMARD regimen.
 
Active joint disease may impair physical activity. Therefore,consultation with a physical therapist, occupa tional therapist and /or nurse trained in rheumatic diseases may be necessary
 
Periods of rest,job modification,time off from work, changes in occupation or termination of of work may be necessary Reconstructive surgery should be considered for patients with end-stage joint damage that is causing unacceptable pain or mobility problems.
 
The initial evaluation of the patient with RA should document symptoms of active disease (i.e. presence of joint pain,duration of morning stiffness,degree of fatigue ) functional status,objective evidence of disease activity (i.e., synovitis, as assessed by tender swollen joint counts and the ESR or CRP level )mechanical joint problems (i.e.,loss of motion, cripitus, instability,and/or deformity ) malalignment,the presence of extraarticular disease,and the presense of radiographic damage.
 
The presence of comorbid conditions should also be assessed. The patient's and physician's global assessments of disease activity and a quantitative assessment of pain using a analog scale or other validated measure of function or quality of life are useful parameters to follow during the course of the disease.
 
The baseline laboratory evaluations should include a complete blood cell count (with white blood cell differential and platelet counts ),rheumatoid factor (RF) measurement,and measurement of ESR or CRP
 
Evaluation of renal and hepatic function is necessary,since many antirheumatic drugs cause renal or hepatic toxicity,and may be contraindictated if these organs are impaired.
 
Since the hands and feet are so frequently involved in RA,radiographs of these joints as well as other affected joints establish a baseline for future assessment of structural damage. Arresting and preventing structural damage is a primary goal of therapy.and radiographic studies of major involved joints may be neded periodically
 
Selection of the treatment regimen requires an assessment of prognosis. Poor prognosis is suggested by earlier age of disease onset,higher titer of RF,elevated ESR,and swelling of > 20 joints, Extraarticular manifestations of RA such as rheumatoid nodules,Sjogren's syndrome,episcleritis and scleritis, interstitial lung disease,pericardial involvement,systemic vasculitis and Felty's syndrome,may indicate a worse prognosis,but they have not ben widely adopted for clinical practice.
 
The ACR criteria for 20 % clinical improvement (the ACR 20) requires a 20 % improvement in the tender and swollen joint count,as well as a 20 % improvement in 3 of the following 5 parameters: 1) Patient's global assessment. 2) Physician's global assessment. 3) Patient's assessment of pain. 4) Patient assessment of degree of disability. 5) Patient assessment level of acute-phase reactant
 
These criteria have been expanded to include criteria for 50 % improvement measures (i.e. ACR 50,ACR 70 )> Other criteria such as the Paulus criteria have also been employed. More recently,radiographic progression (e.g.,the Sharp Score) has been utilized as a outcome measure.
 
Start by trying to find out where the individual who has rheumatoid arthritis is with the particular illness. Different things affect people in different ways. Some people may be very anxious about the future and be coping with the present very well. Others may have difficulty even thinking about how to get up in the morning and proceed with their day. Often start with where the patient is.
 
The initial thing is try to find out is whether they have support from their husband, wife, or other family members. If they're employed, does their boss understand what's going on with them? People need a sense that this illness is not going to isolate them. They need to be understood and have a feeling that other people care about them.
 
Getting support from family members and employers is very important. Oftentimes, feeling understood gratifies people so much - they feel like other people care about them. It's often very important that they discuss the frustration and the depression with their primary physician. The doctor may suggest a referral, so they can have an opportunity to really pour their heart out about what's troubling them and what they're frightened of.
 
A psychiatrist,may suggest the use of antidepressant medication, though not necessarily right away. This often can be quite helpful in lifting someone's mood and also can be helpful in terms of pain control even though it doesn't necessarily do anything for the underlying arthritis process.

Not everyone needs a antidepressent,it depends on their coping skills. It depends on what their previous history has been. If you have someone who has never been ill and all of a sudden has this diagnosis mentioned to them, the way that they react to it will often reflect how they've dealt with other traumas in their life. If there is someone who has had multiple illnesses, this additional illness can often give them an overwhelming sense of "What's going to happen to me?" and a complete loss of control.
 
People like to feel like they're in control of themselves and in control of their health. When this starts to be preyed upon, everyone feels a little bit of loss of self and somewhat of a loss of self-esteem. But we're talking about degrees here.
 
Depression and anger go hand-in-hand, as we all know. What do you tell a person who's living with rheumatoid arthritis and who's frustrated with their inability to do the simple things that they used to be able to do? Number one,try and empathize with them about how difficult that must be. Number two,tell them express themselves, how angry they're feeling, even if they tell the therapist they're not angry. The therapist try to get to the point where they understand that it's very normal to be angry, and they don't need to be afraid of their anger or feel guilty about their anger.
 
The therapist then work with them on how they're going to begin to get some of their expectations met and how they're going to go on in life with a more positive focus rather than being so consumed with the idea that this disease is going to take everything away from them."It's very normal to be angry. Patient's are encouraged to get involved in learning about their illness and in learning about good health in general."
 
As somebody coping with diabetes, which is another long-term chronic condition, sometimes it's not the disease thats the problem, it's the stress of coping with the disease. It always depends on the degree of involvement and how much rheumatoid arthritis takes away from a person's everyday functioning. It is helpful is to get people involved with other rheumatoid arthritis patients so that they hear that their complaints are similar to other patients struggling with the illness. Try to encourage patients to do as many things as possible that they like to do and things that they used to do. Patients need encouragement to get involved in learning about their illness and in learning about good health in general.
 
There are a lot of things like exercise and proper diet which we hear a lot about today that really do make some sense for people who don't have a particular illness. But especially if you have a chronic illness, that's something that you have to watch. The more you can help a person focus on the positive things about their life, the better they're going to be able to tolerate having this particular illness
