Rheumatic fever is a rare inflammation of the heart and other body parts (joints, nervous system, and skin) that usually results from a bout with strep throat. People who develop rheumatic fever tend to have an abnormal immune response to some strains of the Streptococcus bacterium. As their bodies fight this bacterial infection, inflammation occurs in their joints and the tissues of the heart and its internal valves.
Initial symptoms of rheumatic fever are those of strep throat -- sore throat, inflamed tonsils, fever, headache, and aching muscles. Swollen and painful joints (mostly in the knees, elbows, ankles, and wrists) later develop with abdominal pain, skin rash, shortness of breath, and chest pain. Most signs of rheumatic fever appear about one week to six weeks after a case of strep throat.
Complications of rheumatic fever include heart valve damage; heart failure; endocarditis; erratic heartbeats (arrhythmias); and a rare condition called Sydenham's chorea that causes moodiness, weakened muscles, and jerky movements of the face, feet, and hands. Rheumatic fever is treated with antibiotics and anti-inflammatory drugs. People typically recover fully but might need to take low-dose antibiotics for a number of years to prevent any recurrences and further damage to the heart.
Rheumatic fever is a complication of infection with group A Streptococcus bacteria.
Who's at Risk?
Children between the ages of 6 and 15 (more often girls) are at the highest risk of developing rheumatic fever. Those who have weakened immune systems are also more susceptible.
Some cases of rheumatic fever can occur following a "silent" strep throat infection that has no symptoms. The best defense against rheumatic fever is to treat a documented strep throat infection with antibiotics as soon as symptoms appear. If sore throat with a fever higher than 101 degrees Fahrenheit lasts more than 24 hours, contact a physician. Remember, rheumatic fever can lead to heart failure, valve damage or endocarditis, and thus, could be deadly. Look for the symptoms of these heart infections and act to ward off disaster.
Now that you're armed with information about rheumatic fever and endocarditis, you can take measures to prevent getting either infection.
