What is the next step in management for a patient with persistent tonsillitis for 3 weeks and leukocytosis (White Blood Cell count of 16)?

From the Guidelines

For a patient with persistent tonsillitis for 3 weeks and leukocytosis (White Blood Cell count of 16), the next step in management should be to initiate antibiotic therapy with penicillin V (250-500 mg, 2-3 times daily for 10 days) or amoxicillin (50 mg/kg once daily, maximum 1 g, for 10 days), as these are the recommended treatments for Group A Streptococcal (GAS) pharyngitis, which is a common cause of persistent tonsillitis 1.

Key Considerations

• The patient's elevated white blood cell count and prolonged duration of symptoms suggest a bacterial infection that requires antibiotic treatment.
• The American Heart Association recommends penicillin V or amoxicillin as first-line treatments for GAS pharyngitis, with a duration of 10 days 1.
• For patients allergic to penicillin, alternative antibiotics such as narrow-spectrum cephalosporins, clindamycin, azithromycin, or clarithromycin may be used, but with a lower level of evidence (Class IIa, LOE B) 1.

Additional Recommendations

• The patient should be advised to maintain hydration, use salt water gargles (1/2 teaspoon salt in 8 oz warm water) several times daily, and take acetaminophen or ibuprofen for pain and fever as directed on the packaging.
• A follow-up appointment should be scheduled to assess the patient's response to treatment and to consider further evaluation or referral to an ENT specialist if necessary.
• It is essential to note that the patient's symptoms and laboratory results should be closely monitored, and the treatment plan should be adjusted accordingly to prevent potential complications such as peritonsillar abscess or systemic spread of infection.

From the FDA Drug Label

1.3 Pharyngitis and Tonsillitis Cefixime for oral suspension and cefixime capsule is indicated in the treatment of adults and pediatric patients six months of age or older with pharyngitis and tonsillitis caused by susceptible isolates of Streptococcus pyogenes. In the treatment of infections due to Streptococcus pyogenes, a therapeutic dosage of cefixime should be administered for at least 10 days.

The next step in management for a patient with persistent tonsillitis for 3 weeks and leukocytosis (White Blood Cell count of 16) would be to continue or initiate antibiotic therapy with a drug such as cefixime for at least 10 days if the infection is suspected to be caused by Streptococcus pyogenes, as this is a common cause of pharyngitis and tonsillitis 2. However, the specific choice of antibiotic and duration of treatment should be based on culture and susceptibility information when available, or local epidemiology and susceptibility patterns in the absence of such data 2.

From the Research

Patient Management

The patient has persistent tonsillitis for 3 weeks and leukocytosis (White Blood Cell count of 16). To determine the next step in management, we need to consider the cause of the tonsillitis and the appropriate treatment.

Cause of Tonsillitis

• Tonsillitis can be caused by viral or bacterial infections, with group A beta-hemolytic streptococcus (Streptococcus pyogenes) being a common bacterial cause 3.
• The patient's leukocytosis suggests a bacterial infection, but further testing is needed to confirm the cause.

Diagnostic Tools

• Symptom-based validated scoring systems, such as the Centor score, can be used to diagnose tonsillitis 3.
• Oropharyngeal and serum laboratory testing can also be used to confirm the diagnosis and identify the cause of the infection.

Treatment Options

• If the cause of the tonsillitis is confirmed to be group A beta-hemolytic streptococcus, penicillin should be used as the first-line antibiotic 3.
• Alternative antibiotics, such as amoxicillin/clavulanic acid, can be used in patients who are allergic to penicillin or in cases where penicillin is not effective 4, 5.
• Macrolides, such as clarithromycin, can also be used as an alternative to penicillin, but their effectiveness may be limited by resistance 6, 7.

Next Steps

• Further testing is needed to confirm the cause of the patient's tonsillitis and to guide treatment.
• If the cause is confirmed to be bacterial, antibiotic treatment should be initiated, with penicillin being the first-line choice.
• If the patient is allergic to penicillin or if penicillin is not effective, alternative antibiotics should be considered.
