The present disclosure provides methods of diagnosing a subject as having a pulmonary disease or disorder, e.g., an eosinophilic disease or disorder based on the determination of white blood cell ratios. The disclosure also provides white blood cell ratio-based methods of treating, prognosing, or monitoring a pulmonary disease or disorder, as well as methods of methods of predicting a dosage regimen, identifying a candidate therapeutic agent, identifying a patient as a candidate for a therapeutic agent, and methods of designing a personalized therapy.

Methods of diagnosing and treating pulmonary diseases or disorders

Compositions and methods for reducing or preventing graft-versus-host disease associated with allogeneic stem cell transplantation are described. A method includes harvesting hematopoietic cells from a patient with an immunologic disorder and harvesting hematopoietic cells from a donor. The harvested hemaptopoietic cells from the patient and the donor are mixed ex vivo for a period of time sufficient to activate lymphocytes within the hematopoietic cells harvested from the donor such that an immune reaction occurs and an activated portion and an unactivated portion is produced. A rhodamine B derivative is then added to the mixture of cells and the mixture is irradiated at a suitable wavelength and intensity for the selective destruction and/or inactivation of the activated portion without substantially affecting the unactivated portion or causing systemic toxicity in said patient. The irradiated cells are then infused into the patient.

Rhodamine derivatives for photodynamic diagnosis and treatment

The present invention relates to the use of the photoactivable derivatives for the photodynamic treatment for the selective destruction and/or inactivation of immunologically reactive cells without affecting the normal cells and without causing systemic toxicity for the patient, wherein appropriate intracellular levels of said derivatives are achieved and irradiation of a suitable wavelength and intensity is applied.
