A method is presented for treating viral and fungal infections by applying a topical immunosensitizer to the skin of a person infected with a virus or fungus and in need of treatment for the viral or fungal infection. Methods of improving anti-viral and anti-fungal immunity are also presented, and methods of increasing PBMC interferon gamma expression in response to a viral or fungal immune stimulus.

Topical immunosensitizers to treat viral and fungal infections

A method is presented for treating herpes simplex virus (HSV) infection comprising: (a) locally administering a substance that induces a delayed type hypersensitivity (DTH) response to a patient at a site of an HSV lesion to induce a DTH response at the site of the lesion during one or more outbreaks of the HSV infection.

Non-specific delayed-type hypersensitivity response to treat herpes simplex virus infection

The pharmaceutical composition is useful for treating epithelial tumors in a subject and contains at least two antigens and a pharmaceutically acceptable carrier, where each of the antigens induces or is capable of inducing a cutaneous delayed type hypersensitivity (DTH) response in the subject. This composition is particularly useful in treating epithelial tumors, such as warts or verrucae, that are induced by or related to papillomavirus. Antigens useful in the present pharmaceutical composition are anergy panel antigens, such as killed mumps virus, candida extract, trichophyton extract or comparable antigenic extracts. An additional pharmaceutical composition, also useful for treating epithelial tumors, contains at least one antigen that induces or is capable of inducing a cutaneous DTH response in a subject, at least one cytokine or colony stimulating factor and a pharmaceutically acceptable carrier. Kits containing these pharmaceutical compositions are useful for this immunotherapy.

Immunotherapy of epithelial tumors using intralesional injection of antigens that induce a delayed type hypersensitivity reaction

The present immunotherapy relates to a method of treating epithelial tumors and the pharmaceutical compositions and kits useful in treating such tumors. The immunotherapy comprises injecting an effective amount of a pharmaceutical composition containing at least one antigen into the tumor, wherein the antigen is selected for inducing or having the ability to induce a cutaneous delayed type hypersensitivity (DTH) response in the subject prior to the injection of the antigen into the tumors. This immunotherapy is particularly useful in treating epithelial tumors, such as warts or verrucae, that are induced by or related to papillomavirus. Antigens useful in the present immunotherapy are anergy panel antigens, such as killed mumps virus, candida extract, trichophyton extract or comparable antigenic extracts. Additionally, the method optionally includes the injection of an effective amount of at least one cytokine or colony stimulating factor into the tumor either simultaneously with or sequentially to the injection of the antigen. The subject treated by the present immunotherapy is preferably a mammal selected from a human, canine, bovine, feline, equine, ovine or rabbit subject.
