Treatment of Infant Botulism

Introduction to Treatment

The California Department of Public Health and the Centers for Disease Control and Prevention (CDC) recommend immediate administration of BabyBIG® (Human Botulism Immune Globulin Intravenous) for the treatment of infant botulism, which should be obtained through consultation with the California Department of Public Health Infant Botulism Treatment and Prevention Program 1
Upon suspicion of infant botulism, immediate actions include contacting local or state health department for emergency clinical consultation and arranging for BabyBIG® procurement 1

The CDC recommends that infant botulism be treated with BabyBIG® as soon as possible, as early administration is critical, with treatment within 3 days of hospital admission shown to reduce hospital stay, intensive care duration, mechanical ventilation, and tube/IV feeding 1
If BabyBIG® is not available, the American Academy of Pediatrics (AAP) may consider equine botulinum antitoxin (EqBA) as an alternative, which has been shown to reduce hospital stay, ICU stay, mechanical ventilation, and lower sepsis incidence 1
Infant botulism presents with characteristic symptoms, including constipation, poor feeding, weak cry, decreased movement, difficulty sucking or swallowing, and progressive descending flaccid paralysis in severe cases 1

The CDC recommends continuous monitoring for respiratory compromise, mechanical ventilation if needed, and frequent assessment of respiratory function for infants with botulism 1
The AAP also recommends nasogastric or intravenous feeding until swallowing function returns, as well as monitoring of cardiac rhythm, blood pressure, urinary retention, constipation/ileus, and dry mouth and eyes 1
Supportive care may include respiratory support, feeding assistance, and management of complications, and with appropriate treatment, complete recovery is possible 1

The CDC and the AAP advise against feeding honey to infants under 12 months of age, as honey is a known source of C. botulinum spores, and recommend reading food labels carefully to ensure products do not contain honey 1
Parents and caregivers should be aware of other potential risk factors, such as household pet reptiles and certain herbal teas, and carefully read food labels to ensure products do not contain honey 1

The CDC notes that true infant botulism syndrome is caused by intestinal colonization with Clostridium botulinum and in situ toxin production, and if an infant is part of a group outbreak, they likely have ingested preformed toxin and should receive BAT (Botulism Antitoxin Heptavalent) rather than BabyBIG® 1
Infant botulism is a rare but potentially life-threatening condition that occurs when infants ingest Clostridium botulinum spores, which can then colonize the intestine and produce botulinum toxin 1
