Subacute Bacterial Endocarditis (SABE) is a type of endocarditis, an infection of the inner lining of the heart chambers and valves. This condition is generally less aggressive than acute bacterial endocarditis and develops more slowly. Below is an overview of SABE, including its causes, symptoms, diagnosis, treatment, and prevention.
What is Subacute Bacterial Endocarditis?
Subacute Bacterial Endocarditis is a serious heart condition that occurs when bacteria enter the bloodstream and attach to damaged areas of the heartโs endocardium or valves. This can lead to severe complications if not treated promptly.
Causes
SABE is primarily caused by the following bacteria:
- Streptococcus viridans: Commonly found in the mouth, often entering the bloodstream during dental procedures.
- Enterococcus species: Found in the gastrointestinal and urinary tracts.
- Staphylococcus aureus: Though more common in acute endocarditis, it can also cause subacute infections.
Risk factors include:
- Pre-existing heart conditions such as congenital heart defects or valve abnormalities.
- History of endocarditis.
- Intravenous drug use.
- Recent dental or surgical procedures.
- Presence of prosthetic heart valves.
Symptoms
Symptoms of SABE can develop slowly over weeks or months and may include:
- Fever and chills.
- Fatigue and weakness.
- Night sweats.
- Shortness of breath.
- Persistent cough.
- Joint and muscle pain.
- Weight loss.
- Skin changes, such as small red or purple spots on the skin, inside the mouth, or under the fingernails.
Diagnosis
Diagnosing SABE involves several steps:
- Medical History and Physical Examination: Identifying risk factors and checking for signs such as heart murmurs.
- Blood Cultures: To detect the presence of bacteria in the bloodstream.
- Echocardiogram: An ultrasound of the heart to look for vegetations (clumps of bacteria and cells) on the valves.
- Other Imaging Tests: CT or MRI scans to identify complications or areas of infection.
Treatment
Treatment of SABE typically involves:
- Antibiotics: Prolonged course of intravenous antibiotics tailored to the specific bacteria causing the infection.
- Surgery: In severe cases, surgery may be needed to repair or replace damaged heart valves.
- Management of Complications: Treating any heart failure or other complications resulting from the infection.
Prevention
Preventive measures are crucial for individuals at high risk of developing SABE:
- Prophylactic Antibiotics: Given before dental or surgical procedures for those with predisposing heart conditions.
- Good Oral Hygiene: Regular dental check-ups and maintaining good oral health.
- Avoiding Intravenous Drug Use: To reduce the risk of introducing bacteria into the bloodstream.
- Regular Medical Check-ups: Monitoring and managing heart conditions effectively.
Conclusion
Subacute Bacterial Endocarditis (SABE) is a potentially life-threatening infection that requires prompt medical attention. Understanding the causes, recognizing the symptoms, and seeking timely treatment are essential for managing this condition. Preventive measures, especially for those at higher risk, can significantly reduce the likelihood of developing SABE and its associated complications.
