Abstract
Use of low-dose (1,000 IU/dose) oral IFNa as a mixture of all subspecies in specific proportions in the treatment of Acquired immune-deficiency syndrome (AIDS) caused by human immunodeficiency virus types I and II (HIV-I, HIV-II) in both paediatric and adult cases, asymptomatic individuals who are positive for both HIV-I and HIV-II, viral hepatitis, retroviral and retroviral infections, viral stomatitis, myotrophic lateral scerosis, disseminated sclerosis and other chronic degenerative neurological disorders, opportunistic and other microbial infections.
Description
BACKGROUND TO INVENTION
Interferon alpha (IFNcx.) is a family of leukocyte-derived proteins with immunomodulatory, antiproliferative and antiviral properties. Recombinant and natural IFN have been applied in the treatment of hairy cell leukemia, condyloma acuminatum and Kaposi’s sarcoma.
IFN'oC may be produced:
(a) naturally by cells, (b) through hybridization techniques as a recombinant product (c) by cell lines through stimulation with viruses, a procedure commonly referred to a:- Cantell procedure.
The present invention relates to an improved formulation of interferon alpha in the treatment of viral, opportunistic and other microbial infections. Patients suffering from HIV-1 infection and WITH characteristic features of acquired immunodeficiency syndrom (AIDS) treated with low-dose interferon alpha have responded positively. Signs and symptoms that arc routinely associated with AIDS, together with decreased levels lymphocytes bearing CD4+ markers have been observed to resolve without any other treatments. There has also been scrodcconvcrsion in some cases. In addition, positive response has been observed using low-dose oral interferon alpha in viral stomatitis patients. The improved formulation is also applied in the treatment of other viral infections as well as chronic degenerative neurological disorders.
This invention recognizes and supports other related inventions as contained in US Patent Nos. 4,462,985 (1984); 4,497,795(1985); 4,820,514(1989); and 4,820,515(1989). It further supports International Application Publication No. WO88/0341I (1988) published under the Patent Cooperation Treaty (PCT) of the World Interlcclual Property Organization (WIPO).

1. US Patent No. 4.462,985 (1984); Cummins JM
Interferon gycoprotcins isolates of heterologous species origin are subjected to treatment in a digestive environmcl and non-spccie-spccific bioogically active fractions thereofare administered, preferably through digestive tract tissue, to the circulatory system of mammals, including humans, to secure antiviral, antiproliferative (e.g neoplastic) and immunomodulatory (e.g immunopotentiating) effects ordinarily associated only with parenteral administration of homologous species interferon.

2. US-Patent No, 4,497.795 (19S?h Cummins JM
The appetite of a uurm-blooded vertebrate ean be regulated by administering to the vertebrate a biological active fraction of interferon in an amount effective to modulate the vertebrate's food intake or efficiency in utilizing food. The appetite of a cow can be stimulated by the oral or intravenous administration of bovine fibroblast interferon or by interferon secreted nasally by the cow in response to inoculation with a vaccinal virus strain such as that of infectious bovine erhinotraeheitis virus. The appetite of swine can be enhanced by oral administration of bovine fibroblast interferon.
3. US Patent No 4.820.514 (1989): Cummuns JM
A biologically active interferon can be adminstered to an animal in conjunction with the administration of a vaccine to improve the vaccine efficiency and allow the use of a smaller vaccination dose. This procedure will cause a less severe vaccine infection in the animal than if no interferon was administered.
4. US Patent No, 4,820.515 (1989): Cummins JM
Warm-blooded vertebrates can be given very low dosages of interferons, especially huma interferon alpha, to increase efficiency in food utilization. Very low dosages of interferon can also be used to prevent and treat bovine respiratory disease complex. Optimum daily dosages may be as low as 0.10 IU/Ib of body weight and possibly even lower.
5. PCT/WIPO International Publication No. W088Z03411: Cummins JM
Neoplastic disease, hypcrallergenicily, antoimmune disorders characterized by chronic tissue degenerative inflammation an dimmuno-resislanl viral infections are treated by the administration of interferon at a dosage of about 1.0 to about 5 Iu/Ib per day by contacting said interferon with oral/pharyngeal mucosa. Interferon is administered in solution or in a novel solid unitary dosary form adapted to be dissolved in saliva when placed in the mouth.
