ACUTE

foodborne botulism

Back
1st line – 

supportive care

Supportive care is the mainstay of botulism therapy.[41]

Patients with suspected or confirmed botulism should undergo serial vital capacity assessments in the intensive care unit.

In addition, patients should be assessed for the adequacy of gag and cough reflexes, control of oropharyngeal secretions, oxygen saturation, and inspiratory force.

Mechanical ventilation should be considered for any patient with upper airway compromise (due to pharyngeal muscle paralysis) or a decline in vital capacity.

Back
Plus – 

botulism antitoxin

Treatment recommended for ALL patients in selected patient group

Swift administration of antitoxin is essential.[41]

Toxin types A, B, and E account for most cases of foodborne botulism.

In March 2013 the Food and Drug Administration approved the use of the heptavalent botulism antitoxin (HBAT).

HBAT, available only through the Centers for Disease Control and Prevention (CDC), replaces previously licensed botulism antitoxin AB and investigational botulism antitoxin E.[63] The potential for anaphylaxis, delayed allergic reactions (serum sickness), and lifelong sensitization to equine proteins, in addition to short half-lives, limits the use of antitoxins derived from equine plasma (such as HBAT) in the infant (<1 year) population.[64]

A dose of HBAT contains equine-derived antibody to 7 botulinum toxin types (A-G) with a minimum potency of 4500 units of serotype A antitoxin, 3300 units of serotype B antitoxin, 3000 units of serotype C antitoxin, 600 units of serotype D antitoxin, 5100 units of serotype E antitoxin, 3000 units of serotype F antitoxin, and 600 units of serotype G antitoxin.

CDC contact number in US: 770-488-7100 (24-hour line).

Primary options

botulism antitoxin heptavalent (equine): consult specialist for guidance on dose

Back
Consider – 

gastric lavage or enemas

Treatment recommended for SOME patients in selected patient group

Gastric lavage may be attempted if the food exposure was relatively recent.

In the absence of an ileus, enemas may be used to eliminate unabsorbed toxin from the gastrointestinal tract.

Back
1st line – 

supportive care

Supportive care is the mainstay of botulism therapy.[41]

Respiratory status must be monitored closely through frequent monitoring of patient’s respiratory rate, pulse oximetry, and arterial blood gases, as needed.

In addition, patients should be assessed for the adequacy of gag and cough reflexes, control of oropharyngeal secretions, oxygen saturation, and inspiratory force.

Mechanical ventilation should be considered for any patient with upper airway compromise (due to pharyngeal muscle paralysis) or a decline in vital capacity.

Back
Plus – 

botulism immunoglobulin

Treatment recommended for ALL patients in selected patient group

Swift administration of intravenous botulism immunoglobulin (human), also known as BabyBIG™, is essential in infants <1 year of age with botulism type A or B.

It has been shown to be safe and effective for the treatment of infected infants in a randomized, controlled trial. Treatment was associated with reduction in the mean length of hospital stay, duration of mechanical ventilation, and associated costs when compared with treatment with intravenous immunoglobulin.[64][65]

A single dose is used in suspected or confirmed cases. Its half-life is 28 days.

Information and supply is from the California Department of Health Services. Infant Botulism Treatment and Prevention Program Opens in new window

Human-derived botulism immunoglobulin is preferred in the infant (<1 year) population because antitoxins derived from equine plasma (such as heptavalent botulism antitoxin) have shorter half-lives, and have been associated with anaphylaxis, delayed allergic reactions (serum sickness), and lifelong sensitization to equine proteins.[64]

Primary options

botulism immune globulin (human): dose may vary with each manufactured lot; consult specialist for guidance on dose

wound botulism

debridement and antibiotics

Treatment recommended for ALL patients in selected patient group

Patients with wound botulism should undergo careful debridement.

Clostridium botulinum abscess formation may be treated with penicillin G, or metronidazole in penicillin-allergic patients. Aminoglycosides should be avoided in cases of confirmed or suspected botulism as they have been shown to cause neuromuscular blockade, and may therefore potentiate the toxin's effects.[66]

Primary options

debridement

penicillin G potassium: children: consult specialist for guidance on dose; adults: 10-20 million units/day intravenously given in divided doses every 4-6 hours
