RAPID RISK ASSESSMENT - Wound botulism in people who inject heroin: Norway and the United Kingdom
Since December 2014, and as of 10 February 2015, 23 cases of botulism have been reported in Norway (eight cases) and Scotland (15 cases), affecting people who inject drugs (PWID). All the reported cases used heroin, and it is assumed that the source of the infections is contaminated heroin. The batch or batches of the heroin suspected of being contaminated with the spores of Clostridium botulinum have so far not been identified. It is therefore not possible to estimate the volume and distribution of contaminated heroin. However, the clustering of the cases in time and place suggest that the 23 cases could be linked to heroin from a common contaminated batch. People who inject drugs are known to be at risk of wound botulism. Guidance on drug treatment and prevention and control of infections among people who inject drugs has been issued by ECDC and the EMCDDA in 2011 [1]. No person-to-person transmission has ever been reported. The following measures are relevant for mitigating the r...
Wound botulism in injectors of drugs: upsurge in cases in England during 2004
Eurosurveillance, 2005
Wound infections due to Clostridium botulinum were not recognised in the UK and Republic of Ireland before 2000. C. botulinum produces a potent neurotoxin which can cause paralysis and death. In 2000 and 2001, ten cases were clinically recognised, with a further 23 in 2002, 15 in 2003 and 40 cases in 2004. All cases occurred in heroin injectors. Seventy cases occurred in England; the remainder occurred in Scotland (12 cases), Wales (2 cases) and the Republic of Ireland (4 cases). Overall, 40 (45%) of the 88 cases were laboratory confirmed by the detection of botulinum neurotoxin in serum, or by the isolation of C. botulinum from wounds. Of the 40 cases in 2004, 36 occurred in England, and of the 12 that were laboratory confirmed, 10 were due to type A. There was some geographical clustering of the cases during 2004, with most cases occurring in London and in the Yorkshire and Humberside region of northeast England.
MMWR. Morbidity and Mortality Weekly Report, 2019
During September 29-October 6, 2017, the County of San Diego Public Health Services (COSD) was notified of two patients with suspected wound botulism and a history of using black tar heroin. On October 9, COSD, which had reported an average of one wound botulism case per year during 2001-2016, sent a health alert through the California Health Alert Network, notifying Southern California providers of these two patients, including their signs and symptoms and black tar heroin exposure. In collaboration with the California Department of Public Health, COSD conducted an investigation to identify additional cases, determine risk factors for illness, estimate cost of medical care, and develop recommendations to prevent further illness. By April 18, 2018, nine (eight confirmed and one probable) patients with wound botulism were identified, all of whom were hospitalized; one of the nine died. All nine were persons who inject drugs; seven specifically reported using black tar heroin and six practiced subcutaneous injection known as skin popping. Clinically compatible signs and symptoms included muscle weakness, difficulty swallowing, blurred vision, drooping eyelids, slurred speech, difficulty breathing, loss of facial expression, or descending paralysis. All patients were treated with heptavalent botulism antitoxin (BAT). Wound botulism is likely underrecognized because of its rarity and the overlapping signs and symptoms with opioid intoxication, overdose, and other neurologic syndromes including Guillain-Barré syndrome, the Miller Fisher variant of Guillain-Barré syndrome, and myasthenia gravis. Prompt diagnosis, administration of BAT, and provision of supportive care can help stop the progression of paralysis and be lifesaving.
Wound botulism in drug users: a still underestimated diagnosis
Neurological Sciences, 2010
Wound botulism is a rare infectious disease that is becoming a frequent complication of parental drug use. Diagnosis is often difficult and based on clinical suspicion. We report the first Italian case of wound botulism due to intramuscular heroin injection in a 48-year-old man with an acute onset of slurred speech and dysphagia. The most considerable finding of electrophysiological study was the reduction in amplitude of compound muscle action potential which should be considered a useful initial electrodiagnostic sign in the clinical context of botulism. Alerting clinicians to botulism is crucial for a rapid diagnosis and appropriate treatment and thus decreasing mortality and complications.
Botulism and Botulism-like Illness in Chronic Drug Abusers
From 1982 to 1983 we received reports of a neurologic illness characterized by a symmetric descending paralysis in six drug abusers from widely separated geographic areas. Botulism was confirmed in two patients; type B botulinal toxin was found and Clostridium botulinum was isolated from a small abscess in one, and type A botulinal toxin was found in the serum of the other. The clinical illness in the remaining four patients, although not laboratory confirmed, was also compatible with botulism. None of the patients had histories suggestive of foodborne botulism, and wound botulism was suspected as the cause of illness. There are several reports of tetanus associated with parenteral drug abuse; wound botulism is another toxin-mediated clostridial infection that may occur as a complication of chronic drug abuse.

Background Clostridium botulinum remains a major threat to a select population of subcutaneous and intramuscular drug users. We conducted a retrospective study of patients who were diagnosed with wound botulism and their clinical presentations to the Emergency Department (ED). Results A total of 21 patients met the inclusion criteria and all had a confirmed history of heroin use disorder. Initial presentation to the ED included generalized weakness ( n = 20, 95%), difficulty swallowing ( n = 15, 71%), and speech/voice problems ( n = 14, 79%). Sixteen patients (76%) also presented with visible skin wounds and fifteen (71%) required mechanical ventilation (MV). Patients who presented with dysphagia as well as dysarthria and/or dysphonia were more likely to require a percutaneous endoscopic gastrostomy (PEG) tube. Patients who required MV and PEG tubes were noted to have a longer hospital length of stay (LOS) due to the severity of the disease progression. Conclusions Emergency physici...
Botulism in the United States: A Clinical and Epidemiologic Review
Annals of Internal Medicine, 1998
Botulism is caused by a neurotoxin produced from the anaerobic, spore-forming bacterium Clostridium botulinum. Botulism in humans is usually caused by toxin types A, B, and E. Since 1973, a median of 24 cases of foodborne botulism, 3 cases of wound botulism, and 71 cases of infant botulism have been reported annually to the Centers for Disease Control and Prevention (CDC). New vehicles for transmission have emerged in recent decades, and wound botulism associated with black tar heroin has increased dramatically since 1994. Recently, the potential terrorist use of botulinum toxin has become an important concern. Botulism is characterized by symmetric, descending, flaccid paralysis of motor and autonomic nerves, usually beginning with the cranial nerves. Blurred vision, dysphagia, and dysarthria are common initial complaints. The diagnosis of botulism is based on compatible clinical findings; history of exposure to suspect foods; and supportive ancillary testing to rule out other causes of neurologic dysfunction that mimic botulism, such as stroke, the Guillain-Barré syndrome, and myasthenia gravis. Laboratory confirmation of suspected cases is performed at the CDC and some state laboratories. Treatment includes supportive care and trivalent equine antitoxin, which reduces mortality if administered early. The CDC releases botulism antitoxin through an emergency distribution system. Although rare, botulism outbreaks are a public health emergency that require rapid recognition to prevent additional cases and to effectively treat patients. Because clinicians are the first to treat patients in any type of botulism outbreak, they must know how to recognize, diagnose, and treat this rare but potentially lethal disease.
