Neonatal tetanus (trismus nascentium) is a form of generalised tetanus that occurs in newborns. Infants who have not acquired passive immunity from an immunized mother are at risk. It usually occurs through infection of the unhealed umbilical stump, particularly when the stump is cut with a non-sterile instrument.
Tetanus immunoglobulin (TIG), [1] also called tetanus antibodies or tetanus antitoxin. [46] It can be given as intravenous therapy or by intramuscular injection. Antibiotic therapy to reduce toxin production. Metronidazole intravenous (IV) is a preferred treatment. [48] Benzodiazepines can be used to control muscle spasms.
CDC recommends seeking medical attention for evaluation if these signs and symptoms occur during or after the month of PEP. If follow-up laboratory antibody tests reveal HIV infection, HIV treatment specialists should be sought out and PEP should not be discontinued until person is evaluated and treatment plan is established.
Anti-tetanus immunoglobulin, also known as tetanus immune globulin (TIG) and tetanus antitoxin, is a medication made up of antibodies against the tetanus toxin. [1] It is used to prevent tetanus in those who have a wound that is at high risk, have not been fully vaccinated with tetanus toxoid , or have HIV/AIDS .
Tetanus antiserum was developed in 1890, with its protective effects lasting a few weeks. [9] [10] The tetanus toxoid vaccine was developed in 1924, and came into common use for soldiers in World War II. [2] [11] Its use resulted in a 95% decrease in the rate of tetanus. [2] It is on the World Health Organization's List of Essential Medicines. [12]
In 2016, the CDC reported that 80.4% of children in the US had received four or more DTaP vaccinations by 2 years of life. [20] Vaccination rates for children aged 13–17 with one or more TDaP shots was 90.2% in 2019. [20]
Tetanus toxin (TeNT) is an extremely potent neurotoxin produced by the vegetative cell of Clostridium tetani [1] in anaerobic conditions, causing tetanus. It has no known function for clostridia in the soil environment where they are normally encountered. It is also called spasmogenic toxin, tentoxilysin, tetanospasmin, or tetanus neurotoxin.
[6] [1] Tetanospasmin ("tetanus toxin") is a potent toxin with an estimated lethal dose less than 2.5 nanograms per kilogram of body weight, and is responsible for the symptoms of tetanus. [6] [1] Tetanospasmin spreads via the lymphatic system and bloodstream throughout the body, where it is taken up into various parts of the nervous system. [6]
