History And Admission Findings5 heroin addicts (aged 31-44 years; 1 female, 4 men) presented with a history of blurred vision and diplopia followed by dysarthria. 3 of the patients also developed respiratory failure requiring long-term ventilatory support. Physical examination revealed cranial nerve deficits and abscesses at injection sites in 3 of them.DiagnosisIn 4 patients wound botulism was diagnosed on the basis of symptoms, course of the illness and response to specific treatment. Clostridium botulinum was grown from wound swab in one patient.Treatment And CourseTwo of the patients, having been injected with antitoxin immediately after admission, were discharged almost symptom-free after only a few days. Adjuvant antibiotics and, in 3 patients, surgical débridement of the abscesses were needed.ConclusionsProgressive cranial nerve pareses in addicts who inject drugs intravenously or intramuscularly should raise the suspicion of wound botulism and require hospitalization. While indirect demonstration of toxin supports the diagnosis, false-negative results are common.
