This study will examine pathophysiology and immune response of anthrax in infected or exposed individuals to learn more about the disease symptoms, prevention and response to treatment. In addition, it will evaluate immune response to the anthrax vaccine AVA (Anthrax Vaccine Adsorbed) in healthy, non-infected individuals.
The following individuals may be eligible for this study:
Those enrolled in the study will undergo the following tests and procedures.
Infected and exposed individuals:
All infected and exposed individuals will have periodic medical history and physical exam evaluations and be offered treatment or prophylaxis (treatment to prevent infection) with antibiotics, according to the guidelines of the Centers for Disease Control and Prevention (CDC). Patients will be monitored for at least 24 months after antibiotic treatment, or longer if circumstances warrant.
Non-infected, vaccinated individuals
The intentional use of Bacillus anthracis as a bioterrorism weapon with fatal consequences has renewed interest in past epidemiological and animal research about pathogenesis and posed new dilemmas about diagnosis and treatment. Cases in the October 2001 US outbreak were theoretically exposed via the same dispersal method: aerosolization of chemically treated Ames strain spores. While some developed the cutaneous form, others sustained the more serious inhalational disease. Inhaled spores are known to travel to alveolar macrophages and then onto the mediastinal lymph nodes where germination to the bacterium form and toxin release are thought to occur. Infective dose, significance of dormant spores after long-term antibiotic therapy, spectrum of disease and even precise cause of death remain unknown. In this observational, prospective natural history study, participants at various stages of disease or exposure will be followed for at least two years. Persons with acute and resolving disease will undergo laboratory, microbiological, and imaging testing at regular time points and receive standard antimicrobial therapy. In the setting of potential acute exposure, individuals with positive nasal swabs for Bacillus anthracis will be assessed in a similar fashion. Healthy vaccinated participants may also be included to evaluate serum titers in relation to dose and frequency of AVA vaccine.
