Concentrated X-ray contrast media can act as universal antigens and can inhibit or prevent allergic reactions
View Patent ↗The present application is directed to the use of X-ray contrast media that act as universal antigens that are labeled herein as “pseudoantigens.” X-ray contrast media have the potential to exist in an aggregated state that is greater in increased concentrations. In this aggregated state, contrast media assume the role of multivalent antigens and can successfully compete with any other antigens involved in antibody-antigen reactions that lead to anaphylaxis. In this competition, the large quantity of contrast media serves to inhibit the adverse effects of antibody-antigen reactions without the contrast media itself creating antibodies or creating toxicity problems.
1. A method of treating allergic conjunctivitis comprising the step of administering an amount of an X-ray contrast media effective to produce a decrease in histamine release to an eye of a mammal suffering from allergic conjunctivitis, wherein said X-ray contrast media comprises a triiodinated, benzene moiety, wherein said benzene moiety is completely or partially substituted, and wherein said contrast agent is a non-ionic monomer, an ionic monomer, a non-ionic dimer, or an ionic dimer.
2. The method of claim 1 , wherein the X-ray contrast media is selected from the group consisting of IOTROLAN, OPTIRAY, HEXABRIX, IOTHALAMATE, ISOVIST, IOXAGLATE, IOVERSOL and IODIXANOL.
3. The method of claim 1 , wherein the X-ray contrast media is IODIXANOL.
4. A method of treating allergic rhinitis comprising administering an amount of an X-ray contrast media effective to produce a decrease in histamine release into the nose of a mammal suffering from allergic rhinitis wherein said X-ray contrast media comprises a triiodinated, benzene moiety, wherein said benzene moiety is completely or partially substituted, and wherein said contrast agent is a non-ionic monomer, an ionic monomer, a non-ionic dimer, or an ionic dimer.
5. The method of claim 4 , wherein the X-ray contrast media is selected from the group consisting of IOTROLAN, OPTIRAY, HEXABRIX, IOTHALAMATE ISOVIST, IOXAGLATE, IOVERSOL and IODIXANOL.
6. The method of claim 5 , wherein the X-ray contrast media is IODIXANOL.
7. A method of treating allergic conjunctivitis comprising the step of administering an amount of IODIXANOL effective to produce a decrease in histamine release to an eye of a mammal suffering from allergic rhinitis.
8. A method of treating allergic rhinitis comprising administering an amount of IODLXANOL effective to produce a decrease in histamine release into the nose of a mammal suffering from allergic conjunctivitis.
