How to prevent rheumatic fever?

Secondary prevention of rheumatic fever requires antibiotic prophylaxis to reduce the likelihood of recurrent attacks in persons with a history of acute rheumatic fever. Because acute rheumatic fever frequently recurs with subsequent group A strep pharyngitis infections, long-term prophylaxis duration should be individually tailored but is usually indicated at least until age 21. Prophylaxis typically involves an intramuscular injection of benzathine penicillin every 4 weeks or oral penicillin V twice daily. Sulfadiazine or oral macrolides can be taken daily by individuals who are allergic to penicillin. 5,7 Current American Heart Association guidelines no longer recommend bacterial endocarditis prophylaxis for patients with rheumatic heart disease, unless the patient has a prosthetic valve. 8

A 2015 revised version of the Jones Criteria endorsed by the American Heart Association now includes the addition of subclinical carditis as a major criteria and stratification of the major and minor criteria based upon epidemiologic risk (e.g., low, moderate, or high risk populations). 2

What is the best treatment for rheumatic fever?

Primary prevention of acute rheumatic fever is accomplished by proper identification and adequate antibiotic treatment of group A β-hemolytic streptococcal (GAS) tonsillopharyngitis. Diagnosis of GAS pharyngitis is best accomplished by combining clinical judgment with diagnostic test results, the criterion standard of which is the throat culture. Penicillin (either oral penicillin V or injectable benzathine penicillin) is the treatment of choice, because it is cost-effective, has a narrow spectrum of activity, and has long-standing proven efficacy, and GAS resistant to penicillin have not been documented. For penicillin-allergic individuals, acceptable alternatives include a narrow-spectrum oral cephalosporin, oral clindamycin, or various oral macrolides or azalides. The individual who has had an attack of rheumatic fever is at very high risk of developing recurrences after subsequent GAS pharyngitis and needs continuous antimicrobial prophylaxis to prevent such recurrences (secondary prevention). The recommended duration of prophylaxis depends on the number of previous attacks, the time elapsed since the last attack, the risk of exposure to GAS infections, the age of the patient, and the presence or absence of cardiac involvement. Penicillin is again the agent of choice for secondary prophylaxis, but sulfadiazine or a macrolide or azalide are acceptable alternatives in penicillin-allergic individuals. This report updates the 1995 statement by the American Heart Association Rheumatic Fever, Endocarditis, and Kawasaki Disease Committee. It includes new recommendations for the diagnosis and treatment of GAS pharyngitis, as well as for the secondary prevention of rheumatic fever, and classifies the strength of the recommendations and level of evidence supporting them.

How long does rheumatic fever last?

In general, prophylaxis should continue in these patients until the patient reaches 21 years of age or until 5 years has elapsed since the last rheumatic fever attack, whichever is longer (Class I, LOE C). In all situations, the decision to discontinue prophylaxis or to reinstate it should be made after discussion with the patient of the potential risks and benefits and careful consideration of the epidemiological risk factors enumerated above.

How often should I give penicillin?

An injection of 1 200 000 U of this long-acting penicillin preparation every 4 weeks is the recommended regimen for secondary prevention in most circumstances in the United States (Class I, LOE A; Table 4 ). In populations in which the incidence of rheumatic fever is particularly high, the administration of benzathine penicillin G every 3 weeks is justified and recommended, because serum drug levels may fall below a protective level before the fourth week after administration of this dose of penicillin (Class I, LOE A). 69,70 In the United States, the administration of benzathine penicillin G every 3 weeks is recommended only for those who have recurrent acute rheumatic fever despite adherence to an every-4-week regimen (Class I, LOE C). Long-acting penicillin is of particular value in patients with a high risk of rheumatic fever recurrence, especially those with rheumatic heart disease, in whom the consequences of recurrence may be serious. The advantages of benzathine penicillin G must be weighed against the inconvenience to the patient and the pain of injection, which causes some individuals to discontinue prophylaxis. Although there has been concern about the risk of serious allergic reactions in patients receiving long-term intramuscular benzathine penicillin G prophylaxis for rheumatic fever, a large, international, prospective study determined that life-threatening allergic reactions are rare in these patients. 71 It has been demonstrated that the long-term benefits of such prophylaxis far outweigh the risk of serious allergic reactions.

What causes rheumatic fever?

GAS infections of the pharynx are the precipitating cause of rheumatic fever. During epidemics over a half century ago, as many as 3% of untreated acute streptococcal sore throats were followed by rheumatic fever; in endemic infections, the incidence of rheumatic fever is substantially less. 12 Appropriate antibiotic treatment of streptococcal pharyngitis prevents acute rheumatic fever in most cases. 13 Unfortunately, at least one third of episodes of acute rheumatic fever result from inapparent streptococcal infections. 14 In addition, some symptomatic patients do not seek medical care. In these instances, rheumatic fever is not preventable.

How long does it take for penicillin to work?

31 Therefore, a 24- to 48-hour delay to process the throat culture before antibiotic therapy is started does not increase the risk of rheumatic fever.

Is rheumatic fever a recurrence?

The individual who has had an attack of rheumatic fever is at very high risk of developing recurrences after subsequent GAS pharyngitis and needs continuous antimicrobial prophylaxis to prevent such recurrences (secondary prevention).

How to prevent rheumatic fever?

Primary prevention of rheumatic fever is theoretically feasible but practically almost impossible to achieve at the community level. It can be practised on an individual basis by identification of group-A beta hemolytic streptococcal sore throat and use of penicillin to eradicate the streptococci from the throat. Improving public awareness regarding danger of rheumatic fever from sore throat, identification of sore throat as being streptococcal and use of injectable penicillin to cure the streptococcal infection are the measures which are likely to be useful. Primary prevention is difficult to achieve because of the following factors. Only 3 – 20% of sore throats are streptococcal in origin. Of these only 0.3 – 3% result in rheumatic fever. If 10,000 sore throats are treated, of which 300 to 2000 will be streptococcal, it will prevent rheumatic fever in 1 to 6 children. Hence primary prevention is not a feasible option at the community level. Primary prevention is quite difficult to achieve. Oral penicillin may not be effective in preventing rheumatic fever. Rheumatic fever occurred in 15% to 48% children given oral penicillin for 10 days in a US epidemic. 400,000 units of procaine penicillin twice daily for 10 days may be needed.

What is ARF in medical terms?

Introduction. Acute rheumatic fever (ARF) is primarily the result of a bacterial infection with potentially serious consequences for the heart. ARF develops from contact with a specific bacterium called Group A Streptococcus (GAS). 1, 2 After exposure, the body generates antibodies to help destroy the bacteria.

Can a sore throat lead to ARF?

Although not all sore throat leads to ARF, it is important that parents are educated to take their children to the doctor if they have symptoms of a sore throat ( Figure 2 ). The doctor can identify whether the sore throat is attributable to the GAS bacterium by taking a swab and then treating with antibiotics.
