Patent number: 6187767Abstract: The present invention is related to a method for preventing or reducing the effects of ischemia. The ischemia may be associated with injury or reperfusion injury, such as occurs as a result of infarctions, thermal injury (burns), surgical trauma, accidental trauma, hemorrhagic shock and the like. The invention is also related to methods for preventing or reducing bacterial translocation, adult respiratory distress syndrome, adherence of blood cells and platelets to endothelial cells and pulmonary hypertension. In accordance with the present invention, these conditions are prevented or reduced by administering a dehydroepiandrosterone (DHEA) derivative as defined herein.Type: GrantFiled: May 14, 1999Date of Patent: February 13, 2001Assignees: University of Utah Research Foundation, Pharmadigm, Inc.Inventors: Barbara A.

Suitable immune response augmenting agents include, but are not limited to, DHEA, DHEA-derivatives and DHEA congeners.The invention also relates to a method for enhancing a vaccine-induced humoral immune response which comprises administering a vaccine which comprises an antigen and an immunomodulator. The immunomodulator may be an immune response augmenting agent, a lymphoid organ modifying agent or a mixture of the immune response augmenting agent and lymphoid organ modifying agent. Suitable lymphoid organ modifying agents include, but are not limited to, 1,25-dihydroxy Vitamin D.sub.3, 25-hydroxy Vitamin D.sub.3, biologically active 1,25-dihydroxy Vitamin D.sub.3, derivatives which are capable of activating the intra-cellular Vitamin D.sub.Type: GrantFiled: June 7, 1995Date of Patent: November 17, 1998Assignee: University of Utah Research FoundationInventors: Raymond A.

Patent number: 5827841Abstract: Disclosed is a method for enhancing the production of T cell lymphokines, which comprises exposing T cell lymphocytes which have a potential to make selected T cell lymphokines to an appropriate concentration of at least one particular steroid hormone prior to cellular activation. Also disclosed are applications of the method for clinically diagnosing abnormal interleukin production, maintaining in vitro tissue cultures of T cells, overcoming certain types of immunosuppression caused by elevated GCS levels, caused by endogenous production or exogenous administration, use as a vaccine adjuvant to selectively direct the vaccine-induced immune response down a protective, rather than a potentially pathologic or non-protective, immunologic pathway, as a treatment for naturally occuring aging-related decreases in immune function, as a treatment for stress or trauma-induced decreases in immune function, and as a means to facilitate desensitization to agents to which a warm-blooded animal is allergic.Type: GrantFiled: September 20, 1994Date of Patent: October 27, 1998Assignee: University of Utah Research FoundationInventors: Raymond A.

Patent number: 5824313Abstract: The invention relates to a vaccine which comprises an antigen and a lymphoid organ modifying agent. Suitable lymphoid organ modifying agents include, but are not limited to, 1,25-dihydroxy Vitamin D.sub.3, biologically active Vitamin D.sub.3 derivatives which are capable of activating the intracellular Vitamin D.sub.3 receptor, all trans-retinoic acid, retinoic acid derivatives, retinol, retinol derivatives and glucocorticoid. The vaccine composition may further comprise an immune response augmenting agent. The immune response augmenting agent enhances T cell lymphokine production. Suitable immune response augmenting agents include, but are not limited to, dehydroepiandrosterone (DHEA), DHEA congeners and DHEA-derivatives. The invention also relates to a method for inducing an antigen-specific mucosal immune response in a subject vertebrate animal which comprises administering a vaccine which comprises an antigen and a lymphoid organ modifying agent to a site which drains into a peripheral lymph compartment.Type: GrantFiled: June 7, 1995Date of Patent: October 20, 1998Assignee: University of Utah Research FoundationInventors: Raymond A.

Patent number: 5811418Abstract: The present invention is directed to a method for preventing or reducing ischemia following injury, such as reperfusion injury following ischemia, cellular damage associated with ischemic episodes, such as infarctions or traumatic injuries, and thus to prevent or reduce the consequent progressive necrosis of tissue associated with such ischemia. This effect is achieved by administering DHEA, DHEA derivatives or DHEA congeners to a patient as soon as possible after the injury. The present invention is further directed to methods for preventing or reducing bacterial translocation or adult respiratory distress syndrome in a patient. Similarly, bacterial translocation and adult respiratory distress syndrome are prevented or reduced by administering DHEA, DHEA derivatives or DHEA congeners to a patient.Type: GrantFiled: June 7, 1995Date of Patent: September 22, 1998Assignee: University of Utah Research FoundationInventors: Raymond A.
