POSSIBLE CONTAMINATED HEROIN AT RISK OF CAUSING WOUND BOTULISM IN INJECTING DRUG USERS

The Health Protection Agency (HPA) has advised the Department of Health that in the week between 22/02/09 and 02/03/09, five heroin injecting drug users (IDUs) (four males and one female) have been reported to the Health Protection Agency Centre for Infections (HPA CfI), from London, East of England and the South Eastwith clinically diagnosed wound botulism.

Laboratory confirmation of Clostridium botulinum Type B has been reported in three of the cases, two males aged 30 and 45 years old and a female aged 35 years. C. botulinum Type A has been laboratory confirmed in one case - a male aged 38 years old reported to the HPA CfI on 11/01/09. These cases raise the possibility that a batch of heroin is contaminated with the anaerobic bacterium clostridium botulinum.

The HPA has also advised that there has also been a laboratory confirmed case (reported on 26/02/09) of, Clostridium novyi Type A in a Berkshire resident admitted to Hospital on 30/01/2009 with a perineal abscess who later died on 01/02/2009. This individual was injecting heroin into the perineum.

In IDUs, C.novyi and wound botulism result from common problems to do with what they inject and how they inject it. Specifically the use of contaminated heroin, skin popping (injecting into muscle) and heroin that requires the use of more citric acid than usual to dissolve it. All these factors increase the risks of anaerobic growth.

Taken together, the cluster of wound botulism cases in one week and the C.novyi case, are of significance and suggest that IDUs are at potentially increased risk of bacterial infection from a possibly contaminated batch of heroin that is in circulation.

Botulinum antitoxin is effective in reducing the severity of symptoms if administered early in the course of the disease. C. botulinum is sensitive to benzyl penicillin and metronidazole. In cases of wound infection, antimicrobial therapy and surgical debridement should reduce the organism load and therefore toxin production, but circulating toxin can only be neutralised by the early administration of antitoxin. The HPA has advised that where there is definite clinical suspicion of botulism,treatment with antitoxin should not be delayed for microbiological testing.

The Department of Health will be making information directly available through the National Treatment Agency for Substance Misuse and drug user networks, shortly after this alert has been sent to the NHS. The Home Office is also alerting police networks in the UK of the current position.
