[Wound botulism in heroin addicts in Germany]

Area of Science:

• Neurology
• Infectious Diseases
• Toxicology

Background:

• Wound botulism is a rare but severe form of botulism caused by Clostridium botulinum toxin.
• Intravenous drug use is a known risk factor for wound botulism.

Observation:

• Five heroin addicts presented with symptoms including blurred vision, diplopia, dysarthria, and cranial nerve deficits.
• Three patients developed respiratory failure requiring mechanical ventilation.
• Abscesses at injection sites were noted in three patients.

Findings:

• Wound botulism was diagnosed in four patients based on clinical presentation and treatment response.
• Clostridium botulinum was identified in a wound swab from one patient.
• Prompt antitoxin treatment led to rapid symptom improvement in two patients.

Implications:

• Progressive cranial nerve palsies in intravenous drug users should prompt suspicion of wound botulism.
• Hospitalization and specific treatment, including antitoxin and antibiotics, are critical.
• Diagnostic confirmation can be challenging due to potential false-negative toxin assays.
