Ocular involvement in benign botulism B.

Summary
Botulism B food poisoning causes acute eye and dry mouth symptoms. Guanidine treatment improved patient outcomes, while antitoxin was ineffective in later stages.
Area of Science:
- Neurology
- Toxicology
- Ophthalmology
Background:
- Botulism is a rare but serious paralytic illness caused by toxins produced by Clostridium botulinum bacteria.
- Foodborne botulism results from consuming contaminated food, leading to intoxication.
- Clostridium botulinum type B is a common cause of botulism in certain regions.
Observation:
- Nine patients with food poisoning due to botulism B infection presented with acute symptoms.
- Prominent clinical findings included accommodation paresis, mydriasis (dilated pupils), and dry-eye symptoms.
- Impairment of salivary secretion, affecting cholinergic autonomic innervation, persisted for months.
Findings:
- Guanidine hydrochloride demonstrated a beneficial effect in treating the observed symptoms.
- Late-stage administration of antitoxin proved ineffective in this cohort of patients.
- Cholinergic autonomic dysfunction was a significant and prolonged feature of botulism B.
Implications:
- Guanidine may be a viable therapeutic option for managing acute botulism B symptoms, particularly autonomic dysfunction.
- Early diagnosis and intervention are crucial for effective botulism treatment.
- Understanding the long-term effects of botulism B on autonomic function is important for patient management and recovery.
