Compostions and methods for treating chemosensory dysfunction
The invention is directed to a method of detecting a biological substance in the nasal secretion and diagnosing a disease following the detection of the biological substance wherein the biological substance is not related to a respiratory disease. The invention also provides treatment of the diseases following the detection of the biological substance and/or diagnosis of the disease. In some embodiments, the diseases are cancer, hepatitis, smell loss, taste loss, diabetes, and leprosy. The invention also provides a kit for diagnosing a disease. The present invention includes methods of analyzing samples from the nose for the detection of biological substances. In particular, nasal secretion or nasal mucus is collected and analyzed for biological substances. The results of this analysis are then suitable for use in diagnosis, prognosis, and determination of suitability of therapeutic interventions.
1. A method of treating chemosensory dysfunction in a subject, the method comprising nasal administration of a pharmaceutical composition comprising an effective amount of a phosphodiesterase inhibitor to the subject.
2. The method of claim 1 , wherein the phosphodiesterase inhibitor is theophylline.
3. The method of claim 1 , wherein the phosphodiesterase inhibitor is cilostazol.
4. The method of claim 1 , wherein the pharmaceutical composition comprises a pharmaceutically acceptable aqueous solvent.
5. The method of claim 1 , wherein the pharmaceutical composition is a solution or suspension.
6. The method of claim 1 , wherein the pharmaceutical composition is a powder.
7. The method of claim 1 , wherein the chemosensory dysfunction is ageusia, hypogeusia, dysgeusia, anosmia, hyposmia, dysosmia, or a combination thereof.
8. The method of claim 1 , wherein the chemosensory dysfunction is ageusia, hypogeusia, dysgeusia, or a combination thereof.

13. The method of claim 1 , wherein the subject has a decreased level of a cyclic nucleotide in a nasal mucus sample from the subject in comparison to a cyclic nucleotide level of a control population with normal chemosensory function.
14. The method of claim 13 , wherein the cyclic nucleotide is cAMP.
15. The method of claim 13 , wherein the cyclic nucleotide is cGMP.
16. The method of claim 2 , wherein the chemosensory dysfunction is taste loss.
17. The method of claim 3 , wherein the chemosensory dysfunction is taste loss.
18. The method of claim 2 , wherein the chemosensory dysfunction is smell loss.
19. The method of claim 3 , wherein the chemosensory dysfunction is smell loss.
