From the Guidelines
Treatment of a peritonsillar abscess complicated by toxic shock syndrome requires immediate administration of empiric antibiotics, such as clindamycin, within 1 hour of identification, along with early and aggressive source control, including surgical drainage of the abscess. The choice of empiric antibiotics should be guided by the local epidemiology of resistant organisms, as recommended by the Surviving Sepsis Campaign guidelines 1.
Key Considerations
- Empiric antibiotics should be administered promptly, without delay, to reduce morbidity and mortality associated with toxic shock syndrome.
- Clindamycin is a recommended option for the treatment of toxic shock syndrome, particularly in cases with refractory hypotension, due to its ability to inhibit toxin production 1.
- Early and aggressive source control, including surgical drainage of the peritonsillar abscess, is crucial to reduce the bacterial load and prevent further toxin production.
Antibiotic Regimen
- Clindamycin 600-900 mg IV every 8 hours is a suitable option for the treatment of peritonsillar abscess complicated by toxic shock syndrome.
- The addition of other antibiotics, such as penicillin G or beta-lactam antibiotics with beta-lactamase inhibitors, may be considered based on the suspected or confirmed causative organism and local resistance patterns.
Supportive Care
- Aggressive fluid resuscitation and vasopressor support may be necessary to maintain adequate blood pressure and perfusion of vital organs.
- Close monitoring in an intensive care setting is essential to promptly identify and manage any complications or deterioration in the patient's condition.
From the Research
Treatment for Peritonsillar Abscess (PTA) Complicated by Toxic Shock Syndrome (TSS)
- The treatment for PTA complicated by TSS involves abscess drainage and antimicrobial therapy 2, 3, 4.
- Antibiotics should be effective against both aerobic and anaerobic bacteria, with penicillin and metronidazole recommended as the initial regimen 5.
- In cases of TSS, antibiotics should include a penicillinase-resistant penicillin, cephalosporin, or vancomycin, along with either clindamycin or linezolid 4.
- Surgical intervention may be necessary, with options including needle aspiration, incision and drainage, and acute tonsillectomy 2, 3, 6.
- The choice of surgical method and antibiotic regimen may depend on the severity of the infection and the patient's response to treatment 2, 3, 4.
Specific Considerations for TSS
- TSS is a severe, toxin-mediated illness that requires prompt recognition and treatment 4.
- Early symptoms of TSS include fever, chills, malaise, rash, vomiting, diarrhea, and hypotension, with diffuse erythema and desquamation occurring later in the disease course 4.
- Laboratory assessment may demonstrate anemia, thrombocytopenia, elevated liver enzymes, and abnormal coagulation studies 4.
- Treatment of TSS involves intravenous fluids, source control, and antibiotics, with a focus on prompt recognition and treatment to prevent fatal outcomes 4.
Role of Anaerobic Bacteria in PTA
- Anaerobic bacteria, such as Fusobacterium necrophorum (FN), may play a significant role in the development of PTA 3.
- FN has been identified as a prevalent pathogen in PTA, with higher isolation rates in PTA patients compared to electively tonsillectomized controls 3.
- The development of anti-FN antibodies in FN-positive PTA patients suggests a pathogenic role for FN in PTA 3.
