Treatment of Botulism

Treatment of symptomatic botulism following documented or suspected exposure to botulinum neurotoxin serotypes A, B, C, D, E, F, or G;1 9 12 70 105 designated an orphan drug by FDA for treatment of botulism.2

Botulism is a potentially fatal neuroparalytic illness characterized by acute afebrile, symmetric, descending, flaccid paralysis.5 8 9 12 70 105 Caused by neurotoxin produced by Clostridium botulinum;5 8 9 10 12 70 105 certain strains of C. argentinense, C. baratii, and C. butyricum also can produce neurotoxin and cause botulism.9 10 12 70 105 C. botulinum spores are ubiquitous in the environment in soil and water sediments and can germinate into the vegetative bacteria that produce toxin.9 12 70 105 There are 7 known serotypes of botulinum toxin (A, B, C, D, E, F, G) and all cause similar disease;5 8 9 10 12 70 105 naturally occurring human botulism usually involves serotypes A, B, E, and F.5 8 9 10 12 70 105

Foodborne botulism occurs following ingestion of food contaminated with botulinum toxin (e.g., improperly canned food);5 8 9 10 105 symptoms usually begin 12–48 hours (range: 2 hours to 10 days) after ingestion.5 10 70 105 Wound botulism occurs following contamination of wounds with C. botulinum spores from the environment that then germinate and produce botulinum toxin;5 8 9 10 105 time between wound contamination and onset of symptoms usually is 4–14 days.105 Infant botulism occurs when infants <1 year of age ingest C. botulinum spores that then germinate, colonize the GI tract, and produce botulinum toxin;5 8 9 10 105 time between exposure and onset of symptoms estimated to be 3–30 days.105 Intestinal botulism (child or adult) occurs following intestinal colonization with C. botulinum and subsequent production of botulinum toxin.5 8 10

Botulism also could potentially occur from iatrogenic overdose or misinjection of commercially available botulinum toxin used therapeutically (e.g., abobotulinumtoxinA, incobotulinumtoxinA, onabotulinumtoxinA, rimabotulinumtoxinB) or from inhalation of aerosolized botulinum toxin (e.g., in the context of biologic warfare or bioterrorism).8 9 10 12 70 105 Symptoms of botulism may be evident within 12–72 hours following an inhalation exposure.12 70
