[Botulism: Diagnosis and Therapy].

Background  Botulism is a rare, life-threatening, time-critical neuroparalytic disease that is frequently a subject of differential diagnostic considerations. But there is much uncertainty regarding diagnosis and therapy. Rapid diagnosis, early antitoxin dose, consistent food hygiene and the sensitization of the population can help to reduce incidence, morbidity and mortality. Methods  This overview is based on an epidemiological data inquiry (RKI, ECDC, CDC, WHO) and a selective literature research (pubmed till March 2017). Additionally, the German botulism guideline (2012) and own diagnostical experiences were taken into account. Results  The incidence of botulinum toxin intoxication induced by ubiquitous spore-forming Clostridium botulinum (main representative) is < 0.01/100 000 EU citizens. Foodborne botulism is a pure intoxication syndrome (most common form) due to improperly prepared or incorrectly stored food. Wound and infant botulism are kinds of "toxico-infections". A "bulbar" neuroparalysis is a main symptom progressing to a flaccid tetraparesis up to respiratory paralysis. Infant botulism is presented non-specific and is treated only symptomatically; but a special human-derived antitoxin is available at international pharmacies. In case of suspected foodborne or wound botulism antitoxin must be administered as soon as possible, which may also be effective 24 hours after symptoms onset. There is no evidence for adjuvant treatment except of intensive care unit (ICU) therapy. Conclusion  Despite typical symptomatology botulism is often diagnosed too late. Early antitoxin administration and ICU therapy are crucial for survival. A consultant laboratory should be contacted for advice.
