General Information

Rheumatic fever is common worldwide and is responsible for many cases of damaged heart valves. In the Western countries, it became fairly rare since the 1950's, possibly due to higher hygienic standards. While it is far less common in the United States since the beginning of the 20th century, there have been a few outbreaks since the 1980s. Although the disease seldom occurs, it is serious and has a mortality of 2 - 5%.

Rheumatic fever primarily affects children between ages six and 15 and occurs approximately 20 days after strep throat or scarlet fever. In up to a third of cases, the underlying strep infection may not have caused any symptoms.

The rate of development of rheumatic fever in individuals with untreated strep infection is estimated to be 3 percent. The rate of development is far lower in individuals who have received antibiotic treatment. Persons who have suffered a case of rheumatic fever have a tendency to develop flare-ups with repeated strep infections.

The recurrence of rheumatic fever is relatively common in the absence of maintenance of low dose antibiotics, especially during the first three to five years after the first episode of rheumatic fever. Heart complications may be long-term and severe, particularly if the heart valves are involved.

Diagnosis: Modified Jones Criteria

T. Duckett Jones, MD first published these criteria in 1944. They have been periodically revised by the American Heart Association in collaboration with other groups. Two major criteria, or one major and two minor criteria, when there is also evidence of a previous strep infection support the diagnosis of rheumatic fever.

Major Criteria

  • Carditis: inflammation of the heart muscle which can manifest as congestive heart failure with shortness of breath, pericarditis with a rub, or a new heart murmur.
  • Migratory polyarthritis: a temporary migrating inflammation of the large joints, usually starting in the legs and migrating upwards.
  • Sydenham's chorea (St. Vitus' dance): a characteristic series of rapid movements without purpose of the face and arms. This can occur very late in the disease.
  • Erythema marginatum: a long lasting rash that begins on the trunk or arms as macules and spread outward to form a snakelike ring while clearing in the middle. This rash never starts on the face and is made worse with heat.
  • Subcutaneous nodules (a form of Aschoff bodies): painless, firm collections of collagen fibers on the back of the wrist, the outside elbow, and the front of the knees. These now occur infrequently.

Rheumatic fever
From Gale Encyclopedia of Alternative Medicine, 4/6/01 by Amy Cooper


Rheumatic fever (RF) is an illness that occurs as a complication of untreated or inadequately treated strep throat infection. Rheumatic fever causes inflammation of tissues and organs and can result in serious damage to the heart valves, joints, central nervous system and skin.

Rheumatic fever is rare in the United States, though there were outbreaks in both New York City and in Utah in the 1990s. The disease is more prevalent in the developing world, where rheumatic fever is the leading cause of heart disease . In some countries, as many as one to two percent of children are afflicted with it.


Though the exact cause of rheumatic fever is unknown, the disease usually follows the contraction of a throat infection caused by a member of the Group A streptococcus (strep) bacteria (called strep throat). The streptococcus A bacteria has also been linked to many serious diseases, including "flesh-eating" disease and toxic shock syndrome . About 9,700 cases of invasive diseases linked to strep A were reported in the United States in 1997. Rheumatic fever may occur in people of any age, but is most common in children between the ages of five and 15. Poverty, overcrowded living conditions, and inadequate access to medical care increase the likelihood of contracting the disease.

The initial strep throat is easily treated with a 10-day course of antibiotics taken orally. However, when a throat infection occurs without symptoms, or when a patient neglects to take the prescribed medication for the full 10-day course of treatment, there is up to an estimated 3% chance that he or she will develop rheumatic fever. Other types of strep infections (such as of the skin) do not put the patient at risk for RF.

Causes & symptoms

Two different theories exist as to how a bacterial throat infection can result in rheumatic fever. One theory, less supported by research evidence, suggests that the bacteria produce some kind of poisonous chemical (toxin). This toxin is sent into circulation throughout the bloodstream, thus affecting other systems of the body. Research more strongly supports the theory that the disease is caused by an interaction between antibodies produced to fight the group A streptococcus bacteria and the heart tissue. The body produces immune cells (antibodies), that are specifically designed to recognize and destroy invading agents. The antibodies are able to recognize the bacteria because the bacteria contain special markers called antigens on their surface. Due to a resemblance between Group A streptococcus bacteria's antigens and antigens present on the body's own cells, the antibodies mistakenly attack the body itself, specifically heart muscle.

It is interesting to note that members of certain families seem to have a greater tendency to develop rheumatic fever than do others. This could be related to the above theory, in that these families may have cell antigens which more closely resemble streptococcal antigens than do members of other families.

Symptoms of rheumatic fever usually begin one to six weeks after a sore throat . Symptoms may include fatigue and fever, stomach pain and vomiting. In about 75% of all cases of RF one of the first symptoms is arthritis. The joints (especially those of the ankles, knees, elbows, and wrists) become red, hot, swollen, shiny, and extremely painful. Unlike many other forms of arthritis, it may not occur symmetrically (affecting a particular joint on both the right and left sides, simultaneously). Rather, pain may move from joint to joint. The arthritis of RF rarely strikes the fingers, toes, or spine. The joints become so tender that even the touch of bedsheets or clothing is terribly painful.

A peculiar type of involuntary movement, coupled with emotional instability, occurs in about 10% of all RF patients (the figure used to be about 50%). The patient begins experiencing a change in coordination, often first noted by changes in handwriting. The arms or legs may flail or jerk uncontrollably. The patient seems to develop a low threshold for anger and sadness. This feature of RF is called Sydenham's chorea or St. Vitus' dance.

A number of skin changes are common in rheumatic fever patients. A rash called erythema marginatum develops (especially in those patients who will develop heart problems from their illness), which takes the form of pink splotches that may eventually spread into each other. It does not itch. Bumps the size of peas or larger may occur under the skin. These are called subcutaneous nodules; they are hard to the touch, but not painful. These nodules most commonly occur over the knee and elbow joint, as well as over the spine.

The most serious result of RF is called pancarditis (pan means total; carditis refers to inflammation of the heart). Pancarditis is an inflammation that affects all aspects of the heart, including the lining of the heart (endocardium), the sac containing the heart (pericardium), and the heart muscle itself (myocardium). Heart damage caused by RF has the most serious long-term effects. The valves within the heart (structures which allow the blood to flow only in the correct direction, and only at the correct time in the heart's pumping cycle) are frequently damaged, which may result in blood leaking back in the wrong direction, or being unable to pass a stiff, poorly moving valve. Damage to a valve can result in the heart having to work very hard in order to circulate the blood. The heart may not be able to "work around" the damaged valve, which may result in a consistently inadequate amount of blood entering the circulation. About 40-80% of all RF patients develop a form of carditis. Heart damage, however, may not be apparent until months or years after a bout with rheumatic fever. The effect of the disease on the heart also depends on the avoidance of recurrences. The severity of heart damage is often related to the number of attacks of RF a patient experiences.


The initial description of diagnostic criteria for RF were created by William Cheadle in 1889, during a virulent outbreak of the disease in London. In the 1950s, T. Duckett Jones created a list of both major and minor diagnostics for RF. According to the "Jones Criteria," a patient can be diagnosed with RF if he or she exhibits either two major criteria (conditions), or one major and two minor criteria. In either case, it must also be proven that the individual has had a previous infection with streptococcus.

The major criteria include:

  • carditis
  • arthritis
  • chorea
  • subcutaneous nodules
  • erythema marginatum

The minor criteria include:

  • fever
  • joint pain (without actual arthritis)
  • evidence of electrical changes in the heart (determined by measuring electrical characteristics of the heart's functioning during a test called an electrocardiogram, or EKG)
  • evidence (through a blood test) of the presence in the blood of certain proteins, which are produced early in an inflammatory/infectious disease

Tests are also performed to provide evidence of recent infection with group A streptococcal bacteria. The doctor may swab the throat and grow a culture to see if the bacteria will grow and multiply. The culture will be processed and examined to identify streptococcal bacteria. Blood tests can be performed to see if the patient is producing antibodies only made in response to a recent strep infection. A doctor may also do an electrocardiogram in order to check for abnormalities in the heartbeat. An echocardiogram, or ultrasound test, may be ordered to check the heart vales, cardiac function and the heart's structure.


Though there are no proven effective alternative remedies for rheumatic fever itself, alternative methods may help patients with the results and symptoms of the disease, such as pain relief and improved cardiac function. Rheumatoid arthritis can be treated with a number of alternative therapies:

  • Massage: A massage therapist uses gentle strokes to stimulate circulation in and around the joints.
  • Aromatherapy: Often combined with massage, the essential oils of rosemary, benzoin, German chamomile, camphor, juniper, or lavender are used to help relieve pain. Oils of cypress, fennel, lemon, and wintergreen may be used to detoxify or reduce inflammation.
  • Acupuncture: Uses small needles to stimulate appropriate acupoints for pain relief.
  • Osteopathy: Recommends stretching and trigger point therapy to improve mobility, as well as craniofacial massage.

Allopathic treatment

Penicillin is still the most effective treatment for rheumatic fever. A 10-day course of penicillin by mouth, or a single injection of penicillin G is the first line of treatment for RF. Patients will need to remain on some regular dose of penicillin to prevent recurrence of RF. This can mean a small daily dose of penicillin by mouth, or an injection every three weeks. Some practitioners keep patients on this regimen for five years, or until they reach 18 years of age (whichever comes first). Other practitioners prefer to continue treating those patients who will be regularly exposed to streptococcal bacteria (teachers, medical workers), as well as those patients with known RF heart disease.

Of major concern to medical professionals is compliance in taking oral penicillin. A full course of penicillin must be taken to prevent rheumatic fever. However, it is not always easy for patients to follow such a strict regimen. Researchers have found that the time-honored practice of thrice-daily dosing may be unnecessary. Research has shown that twice-daily dosing is just as effective as more frequent doses, and compliance may be improved, since both doses can be administered at home.

Arthritis typically improves quickly when the patient is given a preparation containing aspirin, or some other anti-inflammatory agent (ibuprofen). Mild carditis will also improve with such anti-inflammatory agents; although more severe cases of carditis will require steroid medications. A number of medications are available to treat the involuntary movements of chorea, including diazepam for mild cases, and haloperidol for more severe cases.

Expected results

The long-term prognosis of an RF patient depends primarily on whether he or she develops carditis. This is the only manifestation of RF that can have permanent effects. Those patients with no or mild carditis have an excellent prognosis. Those with more severe carditis have a risk of heart failure, as well as a risk of future heart problems, which may lead to the need for valve replacement surgery.


Initial prevention of rheumatic fever depends upon prompt medical attention. Patients should see a physician if they have sore throat that lasts for more than 24 hours and is accompanied by fever. Treatment of a streptococcal throat infection with an appropriate antibiotic will usually prevent the development of rheumatic fever. Prevention of RF recurrence requires continued antibiotic treatment, perhaps for life. Prevention of complications of already-existing RF heart disease require that the patient always take a special course of antibiotics when he or she undergoes any kind of procedure (even dental cleanings) that might allow bacteria to gain access to the bloodstream.

Because of the prevalence of the Strep A bacteria, it is difficult to completely eradicate rheumatic fever. However, in the late 1990s, some progress was made on identifying a genetic marker for predisposition to the disease. Researchers are also seeking to develop a rapid test for strep which would mean earlier detection and more prompt treatment of strep. In addition, in 1999, testing began on a vaccine against group A streptococcus. The development of such a vaccine was halted in the 1970s after children who received the experimental vaccine developed rheumatic fever. In 1979, the Food and Drug Administration (FDA) prohibited group A strep vaccines from ever being licensed for use, the only vaccine to carry such a prohibition. Clinical trials have been approved by the FDA, however, it will be several years before a vaccine is approved. Doctors at the National Institute of Allergy and Infectious Diseases remain hopeful that a vaccine will someday be available.
