Targeted Antibiotic Treatment for Ludwig's Angina Based on Empirical Evidence

Ludwig's Angina is a severe and potentially life-threatening bacterial infection that originates in the lower part of the floor of the mouth and can spread to the neck. This condition is often polymicrobial, involving both aerobic and anaerobic bacteria.

The most common bacteria causing Ludwig's Angina are streptococci, especially Streptococcus species, which are often linked to dental sources of infection. Various anaerobic bacteria, such as Bacteroides and Fusobacterium species, also contribute to this infection. Less commonly, other aerobic bacteria may be involved, but streptococci and anaerobes predominate as part of a polymicrobial infection.

Poor dental hygiene is the primary cause of Ludwig's Angina, accounting for approximately 90% of reported cases. Other causes include periapical abscesses, trauma or injury, tonsillitis, weak immunity, diabetes, HIV/AIDS, alcohol abuse, malnutrition, and certain dental infections.

In emergency cases, immediate treatment is crucial. Empiric Antibiotic Therapy is the initial antibiotic therapy given to a patient based on the signs and symptoms of Ludwig's Angina when the causative agent is not yet identified. Penicillin + metronidazole is a common empiric antibiotic regimen for Ludwig's Angina, as it has broad-spectrum effects against both aerobic and anaerobic bacteria.

Clindamycin is a first-line treatment for patients who show resistance to penicillin and is a common broad-spectrum drug prescribed. Amoxicillin, given in combination with clavulanic Acid, is another antibiotic that targets aerobic bacteria.

Targeted antibiotic therapy decreases the risk of antibiotic resistance as the person is only exposed to one specific type of antibiotic. However, it is a delayed therapy because the culture test of the bacteria takes time. Clinical guidelines recommend starting empiric therapy immediately if the person shows extreme symptoms, and switching to targeted antibiotic therapy once the bacterial culture results are back.

Symptoms of Ludwig's Angina may include fever, drooling, hoarse voice, difficulty swallowing food, difficulty breathing, limited tongue movement, and swelling in the back of the mouth and neck. If you experience these symptoms, seek medical attention immediately.
