Systemic administration of nac as an adjunct in the treatment of terrorism exposures such as radiation and for prophylaxis

Abstract

The invention is for the combination and related methods of N-acetyl-cysteine oral, inhaled, or intravenous, or glutathione inhaled or intravenous, generally in combination with antibiotic and / or antiviral therapy to ameliorate the toxic effects of infection with materials used in Bioterror incidents such as Bacillus anthracis and smallpox virus, and alternatively, upon exposure to radiation, during testing, and vaccination, as treatment prior to treatment with antibiotic or antiviral therapy to ameliorate the toxic effects of infection and exposure with these organisms.

AI Technical Summary

Benefits of technology

"The patent is about using a combination of N-acetyl-cysteine, glutathione, and antibiotic or antiviral therapy to treat the toxic effects of infection with bioterror agents like Bacillus anthracis and smallpox virus, as well as radiation exposure, during testing or vaccination. The technical effect is to provide a treatment to help mitigate the harmful effects of infection and exposure to these organisms."

Problems solved by technology

In cases of pulmonary anthrax, peribronchial hemorrhagic lymphadenitis blocks pulmonary lymphatic drainage, leading to pulmonary edema.

It is postulated that the macrophage accumulates the IL-1 until a critical level of toxin is reached which causes lysis of the cell and uncontrolled release of the accumulated IL-1 in a large amount that can lead to shock and death.

Dixon, Meselson, Guillemin and Hanna, “Anthrax,” N. Engl. J. Med. 341(11): 815-26, Sep. 9, 1999 specifically note “Unfortunately, anti-toxin preparations are not currently available in the United States.

Viruses cause problems by changing the machinery of the cell that it has commandeered and by creating so many copies of itself that the cell cannot maintain its normal function, ceases functioning normally and may even rupture, releasing large amounts of virus.

The pustules then dry up and shrink, leaving a hard crust that eventually flakes off leaving a sunken scar.

As a biological weapon, smallpox represents a serious threat as it has been reported to carry a case-fatality rate of 30% or more in unvaccinated populations.

The increase in oxidation decreases the available glutathione.

Thus, it may be difficult to identify the etiologic cause of the early stage symptoms of biological weapons or radiation.

Additional factors also play a role in limiting the individual's ability to combat infection.

Stress will also lower the response to vaccination and decrease protection to subsequent infection challenge in pigs immunized with a viral vaccine.

No patent, however, has claimed the use of a combination of NAC and DHEA or its metabolite AED as an immune enhancing combination for the treatment of viral diseases such as smallpox.

As the presence of viral infection will decrease the level of glutathione it is likely that the immunization response may be compromised in individuals who are already carrying smallpox.
