StemCell Therapy

By Dr. Mercola

Rheumatoid arthritis affects about one percent of our population and at least two million Americans have definite or classical rheumatoid arthritis. This number has increased in recent years, as in 2010 about 2.5 percent of white women developed RA.

It is a much more devastating illness than previously appreciated. Most patients with rheumatoid arthritis have a progressive disability.

The natural course of rheumatoid arthritis is quite remarkable in that less than one percent of people with the disease have a spontaneous remission. Some disability occurs in 50-70 percent of people within five years after onset of the disease, and half will stop working within 10 years. The annual cost of this disease in the U.S. is estimated to be over $1 billion.

This devastating prognosis is what makes this novel form of treatment so exciting, as it has a far higher likelihood of succeeding than the conventional approach. Over the years I have treated over 3,000 patients with rheumatic illnesses, including SLE, scleroderma, polymyositis and dermatomyositis.

Approximately 15 percent of these patients were lost to follow-up for whatever reason and have not continued with treatment. The remaining patients seem to have a 60-90 percent likelihood of improvement on this treatment regimen.

This level of improvement is quite a stark contrast to the typical numbers quoted above that are experienced with conventional approaches, and certainly a strong motivation to try the protocol I discuss below.

There is also an increased mortality rate with this disease. The five-year survival rate of patients with more than 30 joints involved is approximately 50 percent. This is similar to severe coronary artery disease or stage IV Hodgkin's disease.

Thirty years ago, one researcher concluded that there was an average loss of 18 years of life in patients who developed rheumatoid arthritis before the age of 50.

Most authorities believe that remissions rarely occur. Some experts feel that the term "remission-inducing" should not be used to describe ANY current rheumatoid arthritis treatment, and a review of contemporary treatment methods shows that medical science has not been able to significantly improve the long-term outcome of this disease.

I first became aware of Doctor Brown's protocol in 1989 when I saw him on 20/20 on ABC. This was shortly after the introduction of the first edition of his book, The Road Back. Unfortunately, Dr. Brown died from prostate cancer shortly after the 20/20 program, so I never had a chance to meet him.

My application of Dr. Brown's protocol has changed significantly since I first started implementing it. Initially, I rigidly followed Dr. Brown's work with minimal modifications to his protocol. About the only change I made was changing Tetracycline to Minocin. I believe I was one of the first physicians who recommended the shift to Minocin, and most people who use his protocol now use Minocin.

In 1939, Dr. Sabin, the discoverer of the polio vaccine, first reported chronic arthritis in mice caused by a mycoplasma. He suggested this agent might cause human rheumatoid arthritis. Dr. Brown worked with Dr. Sabin at the Rockefeller Institute.

Dr. Brown was a board certified rheumatologist who graduated from Johns Hopkins medical school. He was a professor of medicine at George Washington University until 1970 where he served as chairman of the Arthritis Institute in Arlington, Virginia. He published over 100 papers in peer reviewed scientific literatureHe was able to help over 10,000 patients when he used this program, from the 1950s until his death in 1989, and clearly far more than that have been helped by other physicians using this protocol.

He found that significant benefits from the treatment require, on average, about one to two years. I have treated nearly 3000 patients and find that the dietary modification I advocate, which I started to integrate in the early 1990s, accelerates the response rate to several months. I cannot emphasize strongly enough the importance of this aspect of the program.

Still, the length of therapy can vary widely. In severe cases, it may take up to 30 months for patients to gain sustained improvement. One requires patience because remissions may take up to three to five years. Dr. Brown's pioneering approach represents a safer, less toxic alternative to many conventional regimens and results of the NIH trial have finally scientifically validated this treatment.

The dietary changes are absolutely an essential component of my protocol. Dr. Brown's original protocol was notorious for inducing a Herxheimer, or worsening of symptoms, before improvement was noted. This could last two to six months. Implementing my nutrition plan resulted in a lessening of that reaction in most cases.

When I first started using his protocol for patients in the late '80s, the common retort from other physicians was that there was "no scientific proof" that this treatment worked. Well, that is certainly not true today. A review of the bibliography will provide over 200 references in the peer-reviewed medical literature that supports the application of Minocin in the use of rheumatic illnesses.

In my experience, nearly 80 percent of people do remarkably better with this program. However, approximately five percent continue to worsen and require conventional agents, like methotrexate, to relieve their symptoms.

The definitive scientific support for minocycline in the treatment of rheumatoid arthritis came with the MIRA trial in the United States. This was a double blind randomized placebo controlled trial done at six university centers involving 200 patients for nearly one year. The dosage they used (100 mg twice daily) was much higher and likely less effective than what most clinicians currently use.

They also did not employ any additional antibiotics or nutritional regimens, yet 55 percent of patients improved. This study finally provided the "proof" that many traditional clinicians demanded before seriously considering this treatment as an alternative regimen for rheumatoid arthritis.

Dr. Thomas Brown's effort to treat the chronic mycoplasma infections believed to cause rheumatoid arthritis is the basis for this therapy. Dr. Brown believed that most rheumatic illnesses respond to this treatment. He and others used this therapy for SLE, ankylosing spondylitis, scleroderma, dermatomyositis, and polymyositis.

Dr. Osler was one of the most well respected and prominent physicians of his time (1849- 1919), and many regard him as the consummate physician of modern times. An excerpt from a commentary on Dr. William Osler provides a useful perspective on application of alternative medical paradigms:

Osler would caution us against the arrogance of believing that only our current medical practices can benefit the patient. He would realize that new scientific insights might emerge from as yet unproved beliefs. Although he would fight vigorously to protect the public against frauds and charlatans, he would encourage critical study of whatever therapeutic approaches were reliably reported to be beneficial to patients.

There are many variables associated with an increased chance of remission or improvement.

Although I used a revision of his antibiotic approach for nearly 10 years, my particular prejudice is to focus on natural therapies. The program that follows is my revision of this protocol that allows for a completely drug-free treatment of RA, which is based on my experience of treating over 3000 patients with rheumatic illnesses in my Chicago clinic.

If you are interested in reviewing or considering Dr. Brown's antibiotic approach, I have included a summary of his work and the evidence for it in the appendix.

Improving your diet using a combination of my nutritional guidelines, nutritional typing is crucial for your success. In addition, there are some general principles that seem to hold true for all nutritional types and these include:

With the vast majority of the patients I treated, some type of emotional trauma occurred early in their life, before the age their conscious mind was formed, which is typically around the age of 5 or 6. However, a trauma can occur at any age, and has a profoundly negative impact.

If that specific emotional insult is not addressed with an effective treatment modality then the underlying emotional trigger will continue to fester, allowing the destructive process to proceed, which can predispose you to severe autoimmune diseases like RA later in life.

In some cases, RA appears to be caused by an infection, and it is my experience that this infection is usually acquired when you have a stressful event that causes a disruption in your bioelectrical circuits, which then impairs your immune system.

This early emotional trauma predisposes you to developing the initial infection, and also contributes to your relative inability to effectively defeat the infection.

Therefore, it's very important to have an effective tool to address these underlying emotional traumas. In my practice, the most common form of treatment used is called the Emotional Freedom Technique (EFT).

Although EFT is something that you can learn to do yourself in the comfort of your own home, it is important to consult a well-trained professional to obtain the skills necessary to promote proper healing using this amazing tool.

The early part of the 21st century brought enormous attention to the importance and value of vitamin D, particularly in the treatment of autoimmune diseases like RA. From my perspective, it is now virtually criminal negligent malpractice to treat a person with RA and not aggressively monitor their vitamin D levels to confirm that they are in a therapeutic range of 50-70 ng/ml.

This is so important that blood tests need to be done every two weeks, so the dose can be adjusted to get into that range. Most normal-weight adults should start at 10,000 units of vitamin D per day. If you are in the US, then Lab Corp is the lab of choice. For more detailed information on vitamin D, you can review my vitamin D resource page.

The best way to raise your blood levels is by sensible exposure to large amounts of your skin. Most can't do this in the winter so if you take supplements make sure to take 500 mg to 1000 mg of magnesium and 150 mcg of vitamin K2, (not 1) which are important cofactors for optimizing vitamin D function.

One new addition to the protocol is low-dose Naltrexone, which I would encourage anyone with RA to try. It is inexpensive and non-toxic and I have a number of physician reports documenting incredible efficacy in getting people off of all their dangerous arthritis meds. Although this is a drug, and strictly speaking not a natural therapy, it has provided important relief and is FAR safer than the toxic drugs that are typically used by nearly all rheumatologists.

Your gut controls about 80% of your immune response so it is absolutely crucial that you optimize the bacterial colonies growing there. It is imperative to stop eating all refined sugars and processed foods and replace them with REAL food that is not processed. This will limit the growth of gut pathogens.

Ideally it would be great to add fermented vegetables as you can input many trillions of beneficial bacteria by this inexpensive food that you can make at home. If this is not an option for you than you would benefit from taking a high quality high potency probiotic but that will not provide as many bacteria and will be more expensive.

Limiting sugar is a critical element of the treatment program. Sugar has multiple significant negative influences on your biochemistry. First and foremost, it increases your insulin levels, which is the root cause of nearly all chronic disease. It can also impair your gut bacteria.

In my experience if you are unable to decrease your sugar intake, you are far less likely to improve. Please understand that the number one source of calories in the US is high fructose corn syrup from drinking soda. One of the first steps you can take is to phase out all soda, and replace it with pure, clean water.

It is very important to exercise and increase muscle tone of your non-weight bearing joints. Experts tell us that disuse results in muscle atrophy and weakness. Additionally, immobility may result in joint contractures and loss of range of motion (ROM). Active ROM exercises are preferred to passive There is some evidence that passive ROM exercises increase the number of white blood cells (WBCs) in your joints.

If your joints are stiff, you should stretch and apply heat before exercising. If your joints are swollen, application of 10 minutes of ice before exercise would be helpful.

The inflamed joint is very vulnerable to damage from improper exercise, so you must be cautious. People with arthritis must strike a delicate balance between rest and activity, and must avoid activities that aggravate joint pain. You should avoid any exercise that strains a significantly unstable joint.

A good rule of thumb is that if the pain lasts longer than one hour after stopping exercise, you should slow down or choose another form of exercise. Assistive devices are also helpful1 to decrease the pressure on affected joints. Many patients need to be urged to take advantage of these. The Arthritis Foundation has a book, Guide to Independent Living, which instructs patients about how to obtain them. Of course, it is important to maintain good cardiovascular fitness as well. Walking with appropriate supportive shoes is another important consideration. If your condition allows, it would be wise to move toward a Peak Fitness program that is designed for reaching optimal health.

One of the primary problems with RA is controlling pain. The conventional treatment typically includes using very dangerous drugs like prednisone, methotrexate, and drugs that interfere with tumor necrosis factor, like Enbrel. The goal is to implement the lifestyle changes discussed above as quickly as possible, so you can start to reduce these toxic and dangerous drugs, which do absolutely nothing to treat the cause of the disease. However, pain relief is obviously very important, and if this is not achieved, you can go into a depressive cycle that can clearly worsen your immune system and cause the RA to flare. So the goal is to be as comfortable and pain free as possible with the least amount of drugs. The Mayo Clinic offers several common sense guidelines2 for avoiding pain by paying heed to how you move, so as to not injure your joints.

Clearly the safest prescription drugs to use for pain are the non-acetylated salicylates such as:

They are the drugs of choice if there is renal insufficiency, as they minimally interfere with anticyclooxygenase and other prostaglandins. Additionally, they will not impair platelet inhibition in those patients who are on an every-other-day aspirin regimen to decrease their risk for stroke or heart disease.

Unlike aspirin, they do not increase the formation of products of lipoxygenase-mediated metabolism of arachidonic acid. For this reason, they may be less likely to cause hypersensitivity reactions. These drugs have been safely used in patients with reversible obstructive airway disease and a history of aspirin sensitivity.

They are also much gentler on your stomach than the other NSAIDs and are the drug of choice if you have problems with peptic ulcer disease. Unfortunately, all these benefits are balanced by the fact that they may not be as effective as the other agents and are less convenient to take. You need to take 1.5-2 grams twice a day, and tinnitus, or ringing in your ear, is a frequent side effect.

You need to be aware of this complication and know that if tinnitus does develop, you need to stop the drugs for a day and restart with a dose that is half a pill per day lower. You can repeat this until you find a dose that relieves your pain and doesn't cause any ringing in your ears.

If the non-acetylated salicylates aren't helping, there are many different NSAIDs to try. Relafen, Daypro, Voltaren, Motrin, Naprosyn. Meclomen, Indocin, Orudis, and Tolectin are among the most toxic or likely to cause complications. You can experiment with them, and see which one works best for you. If cost is a concern, generic ibuprofen can be used at up to 800 mg per dose. Unfortunately, recent studies suggest this drug is more damaging to your kidneys. If you use any of the above drugs, though, it is really important to make sure you take them with your largest meal as this will somewhat moderate their GI toxicity and the likelihood of causing an ulcer.

Please beware that they are much more dangerous than the antibiotics or non-acetylated salicylates. You should have an SMA blood test performed at least once a year if you are on these medications. In addition, you must monitor your serum potassium levels if you are on an ACE inhibitor as these medications can cause high potassium levels. You should also monitor your kidney function. The SMA will show any liver impairment the drugs might be causing.

These medications can also impair prostaglandin metabolism and cause papillary necrosis and chronic interstitial nephritis. Your kidney needs vasodilatory prostaglandins (PGE2 and prostacyclin) to counterbalance the effects of potent vasoconstrictor hormones such as angiotensin II and catecholamines. NSAIDs decrease prostaglandin synthesis by inhibiting cyclooxygenase, leading to unopposed constriction of the renal arterioles supplying your kidney.

The first non-aspirin NSAID, indomethacin, was introduced in 1963. Now more than 30 are available. Relafen is one of the better alternatives as it seems to cause less of an intestinal dysbiosis. You must be especially careful to monitor renal function periodically. It is important to understand and accept the risks associated with these more toxic drugs. Every year, they do enough damage to the GI tract to kill 2,000 to 4,000 people with rheumatoid arthritis alone. That is 10 people EVERY DAY. At any given time, 10 to 20 percent of all those receiving NSAID therapy have gastric ulcers.

If you are taking an NSAID, you are at approximately three times greater risk for developing serious gastrointestinal side effects than those who don't. Approximately 1.2 percent of patients taking NSAIDs are hospitalized for upper GI problems, per year of exposure. One study of patients taking NSAIDs showed that a life-threatening complication was the first sign of ulcer in more than half of the subjects. Researchers found that the drugs suppress production of prostacyclin, which is needed to dilate blood vessels and inhibit clotting. Earlier studies had found that mice genetically engineered to be unable to use prostacyclin properly were prone to clotting disorders.

Anyone who is at increased risk of cardiovascular disease should steer clear of these medications. Ulcer complications are certainly potentially life-threatening, but heart attacks are a much more common and likely risk, especially in older individuals.

Risk factor analysis can help determine if you will face an increased danger of developing these complications. If you have any of the following, you will likely to have a higher risk of side effects from these drugs:

The above drug class are called non steroidal anti inflammatories (NSAIDs). If they are unable to control the pain, then prednisone is nearly universally used. This is a steroid drug that is loaded with side effects. If you are on large doses of prednisone for extended periods of time, you can be virtually assured that you will develop the following problems:

You can be virtually assured that every time you take a dose of prednisone your bones are becoming weaker. The higher the dose and the longer you are on prednisone, the more likely you are to develop the problems. However, if you are able to keep your dose to 5 mg or below, this is not typically a major issue. Typically this is one of the first medicines you should try to stop as soon as your symptoms permit.

Beware that blood levels of cortisol peak between 3 and 9am. It would, therefore, be safest to administer the prednisone in the morning. This will minimize the suppression on your hypothalamic-pituitary-adrenal axis. You also need to be concerned about the increased risk of peptic ulcer disease when using this medicine with conventional non-steroidal anti-inflammatories. If you are taking both of these medicines, you have a 15 times greater risk of developing an ulcer!

If you are already on prednisone, it is helpful to get a prescription for 1 mg tablets so you can wean yourself off the prednisone as soon as possible. Usually you can lower your dose by about 1 mg per week. If a relapse of your symptoms occurs, then further reduction of the prednisone is not indicated.

Unlike conventional approaches to RA, my protocol is designed to treat the underlying cause of the problem. So eventually the drugs that you are going to use during the program will be weaned off. The following criteria can help determine when you are in remission and can consider weaning off your medications:

If you discontinue your medications before all of the above criteria are met, there is a greater risk that the disease will recur. If you meet the above criteria, you can try to wean off your anti-inflammatory medication and monitor for flare-ups. If no flare-ups occur for six months, then discontinue the clindamycin. If the improvements are maintained for the next six months, you can then discontinue your Minocin and monitor for recurrences. If symptoms should recur, it would be wise to restart the previous antibiotic regimen.

If you have received evaluations and treatment by one or more board certified rheumatologists, you can be very confident that the appropriate evaluation was done. Although conventional treatments fail miserably in the long run, the conventional diagnostic approach is typically excellent, and you can start the treatment program discussed above. If you have not been evaluated by a specialist then it will be important to be properly evaluated to determine if indeed you have rheumatoid arthritis. Please be sure and carefully review Appendix Two, as you will want to confirm that fibromyalgia is not present.

Beware that arthritic pain can be an early manifestation of 20-30 different clinical problems. These include not only rheumatic disease, but also metabolic, infectious and malignant disorders. Rheumatoid arthritis is a clinical diagnosis for which there is not a single test or group of laboratory tests that can be considered confirmatory.

You must also make certain that the first four symptoms listed in the table above are present for six or more weeks. These criteria have a 91-94 percent sensitivity and 89 percent specificity for the diagnosis of rheumatoid arthritis.

However, these criteria were designed for classification and not for diagnosis. The diagnosis must be made on clinical grounds. It is important to note that many patients with negative serologic tests can have a strong clinical picture for rheumatoid arthritis.

In a way, the hands are the calling card of rheumatoid arthritis. If you completely lack hand and wrist involvement, even by history, the diagnosis of rheumatoid arthritis is doubtful. Rheumatoid arthritis rarely affects your hips and ankles early in its course.

The metacarpophalangeal joints, proximal interphalangeal and wrist joints are the first joints to become symptomatic. Osteoarthritis typically affects the joints that are closest to your fingertips (DIP joints) while RA typically affects the joints closest to your wrist (PIP), like your knuckles.

Fatigue may be present before your joint symptoms begin, and morning stiffness is a sensitive indicator of rheumatoid arthritis. An increase in fluid in and around your joint probably causes the stiffness. Your joints are warm, but your skin is rarely red. When your joints develop effusions, hold them flexed at 5 to 20 degrees as it is likely going to be too painful to extend them fully.

Radiological changes typical of rheumatoid arthritis on PA hand and wrist X-rays, which must include erosions or unequivocal bony decalcification localized to, or most marked, adjacent to the involved joints (osteoarthritic changes alone do not count). Note: You must satisfy at least four of the seven criteria listed. Any of criteria 1-4 must have been present for at least 6 weeks. Patients with two clinical diagnoses are not excluded. Designations as classic, definite, or probable rheumatoid arthritis, are not to be made.

The general initial laboratory evaluation should include a baseline ESR, CBC, SMA, U/A, 25 hydroxy D level and an ASO titer. You can also draw RF and ANA titers to further objectively document improvement with the therapy. However, they seldom add much to the assessment. Follow-up visits can be every two to four months depending on the extent of the disease and ease of testing. The exception here would be vitamin D testing, which should be done every two weeks until your 25 hydroxy D level is between 65 and 80 ng/ml.

Many patients with rheumatoid arthritis have a hypochromic, microcytic CBC that appears very similar to iron deficiency, but it is not at all related. This is probably due to the inflammation in the rheumatoid arthritis impairing optimal bone marrow utilization of iron.

It is important to note that this type of anemia does NOT respond to iron and if you are put on iron you will get worse, as the iron is a very potent oxidative stress. Ferritin levels are generally the most reliable indicator of total iron body stores. Unfortunately it is also an acute phase reactant protein and will be elevated anytime the ESR is elevated. This makes ferritin an unreliable test in patients with rheumatoid arthritis.

Roadback.org is the oldest organization promoting this work and the one Dr. Brown originally worked with. They are an excellent resource to find health care professionals using this approach.

It is quite clear that autoimmunity plays a major role in the progression of rheumatoid arthritis. Most rheumatology investigators believe that an infectious agent causes rheumatoid arthritis. There is little agreement as to the involved organism, however. Investigators have proposed the following infectious agents:

This review will focus on the evidence supporting the hypothesis that mycoplasma is a common etiologic agent of rheumatoid arthritis. Mycoplasmas are the smallest self-replicating prokaryotes. They differ from classical bacteria by lacking rigid cell wall structures and are the smallest known organisms capable of extracellular existence. They are considered parasites of humans, animals, and plants.

Mycoplasmas have limited biosynthetic capabilities and are very difficult to culture and grow from synovial tissues. They require complex growth media or a close parasitic relation with animal cells. This contributed to many investigators' failure to isolate them from arthritic tissue.

In reactive arthritis, immune complexes rather than viable organisms localize in your joints. The infectious agent is actually present at another site. Some investigators believe that the organism binding in the immune complex contributes to the difficulty in obtaining positive mycoplasma cultures.

Despite this difficulty, some researchers have successfully isolated mycoplasma from synovial tissues of patients with rheumatoid arthritis. A British group used a leucocyte-migration inhibition test and found two-thirds of their rheumatoid arthritis patients to be infected with Mycoplasma fermentens. These results are impressive since they did not include more prevalent Mycoplasma strains like M salivarium, M ovale, M hominis, and M pneumonia. One Finnish investigator reported a 100 percent incidence of isolation of mycoplasma from 27 rheumatoid synovia using a modified culture technique. None of the non-rheumatoid tissue yielded any mycoplasmas.

The same investigator used an indirect hemagglutination technique and reported mycoplasma antibodies in 53 percent of patients with definite rheumatoid arthritis. Using similar techniques, other investigators have cultured mycoplasma in 80-100 percent of their rheumatoid arthritis test population. Rheumatoid arthritis can also follow some mycoplasma respiratory infections.

One study of over 1,000 patients was able to identify arthritis in nearly one percent of the patients. These infections can be associated with a positive rheumatoid factor. This provides additional support for mycoplasma as an etiologic agent for rheumatoid arthritis. Human genital mycoplasma infections have also caused septic arthritis.

Harvard investigators were able to culture mycoplasma or a similar organism, ureaplasma urealyticum, from 63 percent of female patients with SLE and only four percent of patients with CFS. The researchers chose CFS, as these patients shared similar symptoms as those with SLE, such as fatigue, arthralgias, and myalgias.

The full spectrum of human rheumatoid arthritis immune responses (lymphokine production, altered lymphocyte reactivity, immune complex deposition, cell-mediated immunity, and development of autoimmune reactions) occurs in mycoplasma induced animal arthritis Investigators have implicated at least 31 different mycoplasma species. Mycoplasma can produce experimental arthritis in animals from three days to months later. The time seems to depend on the dose given, and the virulence of the organism. There is a close degree of similarity between these infections and those of human rheumatoid arthritis.

Mycoplasmas cause arthritis in animals by several mechanisms. They either directly multiply within the joint or initiate an intense local immune response. Arthritogenic mycoplasmas also cause joint inflammation in animals by several mechanisms. They induce nonspecific lymphocyte cytotoxicity and antilymphocyte antibodies as well as rheumatoid factor.

Mycoplasma clearly causes chronic arthritis in mice, rats, fowl, swine, sheep, goats, cattle, and rabbits. The arthritis appears to be the direct result of joint infection with culturable mycoplasma organisms.

Gorillas have tissue reactions closer to man than any other animal, and investigators have shown that mycoplasma can precipitate a rheumatic illness in gorillas. One study demonstrated that mycoplasma antigens do occur in immune complexes in great apes.

The human and gorilla IgG are very similar and express nearly identical rheumatoid factors (IgM anti-IgG antibodies). The study showed that when mycoplasma binds to IgG it can cause a conformational change. This conformational change results in an anti-IgG antibody, which can then stimulate an autoimmune response.

If mycoplasma were a causative factor in rheumatoid arthritis, one would expect tetracycline type drugs to provide some sort of improvement in the disease. Collagenase activity increases in rheumatoid arthritis and probably has a role in its cause. Investigators have demonstrated that tetracycline and minocycline inhibit leukocyte, macrophage, and synovial collagenase.

There are several other aspects of tetracyclines that may play a role in rheumatoid arthritis. Investigators have shown minocycline and tetracycline to retard excessive connective tissue breakdown and bone resorption, while doxycycline inhibits digestion of human cartilage. It is also possible that tetracycline treatment improves rheumatic illness by reducing delayed-type hypersensitivity response. Minocycline and doxycycline both inhibit phosolipases, which are considered proinflammatory and capable of inducing synovitis. Minocycline is a more potent antibiotic than tetracycline and penetrates tissues better.

These characteristics shifted the treatment of rheumatic illness away from tetracycline to minocycline. Minocycline may benefit rheumatoid arthritis patients through its immunomodulating and immunosuppressive properties. In vitro studies have demonstrated a decreased neutrophil production of reactive oxygen intermediates along with diminished neutrophil chemotaxis and phagocytosis.

Minocycline has also been shown to reduce the incidence and severity of synovitis in animal models of arthritis. The improvement was independent of minocycline's effect on collagenase. Minocycline has also been shown to increase intracellular calcium concentrations that inhibit T-cells. Individuals with the Class II major histocompatibility complex (MHC) DR4 allele seem to be predisposed to developing rheumatoid arthritis.

The infectious agent probably interacts with this specific antigen in some way to precipitate rheumatoid arthritis. There is strong support for the role of T cells in this interaction. So minocycline may suppress rheumatoid arthritis by altering T cell calcium flux and the expression of T cell derived from collagen binding protein. Minocycline produced a suppression of the delayed hypersensitivity in patients with Reiter's syndrome, and investigators also successfully used minocycline to treat the arthritis and early morning stiffness of Reiter's syndrome.

In 1970, investigators at Boston University conducted a small, randomized placebo-controlled trial to determine if tetracycline would treat rheumatoid arthritis. They used 250 mg of tetracycline a day. Their study showed no improvement after one year of tetracycline treatment. Several factors could explain their inability to demonstrate any benefits. Their study used only 27 patients for a one-year trial, and only 12 received tetracycline, so noncompliance may have been a factor. Additionally, none of the patients had severe arthritis. Patients were excluded from the trial if they were on any anti-remittive therapy.

Finnish investigators used lymecycline to treat the reactive arthritis in Chlamydia trachomatous infections. Their study compared the effect of the medication in patients with two other reactive arthritis infections: Yersinia and Campylobacter.

Lymecyline produced a shorter course of illness in the Chlamydia induced arthritis patients, but did not affect the other enteric infections-associated reactive arthritis. The investigators later published findings that suggested lymecycline achieved its effect through non-antimicrobial actions. They speculated it worked by preventing the oxidative activation of collagenase.

The first trial of minocycline for the treatment of animal and human rheumatoid arthritis was published by Breedveld. In the first published human trial, Breedveld treated 10 patients in an open study for 16 weeks. He used a very high dose of 400 mg per day. Most patients had vestibular side effects resulting from this dose.

However, all patients showed benefit from the treatment, and all variables of efficacy were significantly improved at the end of the trial. Breedveld expanded on his initial study and later observed similar impressive results. This was a 26-week double-blind placebo-controlled randomized trial with minocycline for 80 patients They were given 200 mg twice a day. The Ritchie articular index and the number of swollen joints significantly improved (p < 0.05) more in the minocyline group than in the placebo group. Investigators in Israel studied 18 patients with severe rheumatoid arthritis for 48 weeks.
