Methods of identifying responders to dopamine agonist therapy and treating metabolic conditions thereof

1. A method of identifying patients to be treated by dopamine agonist therapy comprising the steps of:

analyzing a plasma or urine sample from said patient for concentrations of norepinephrine (NE), norepinephrine metabolites (NE metabolites), dopamine, dopamine metabolites, serotonin, serotonin metabolites, or fasting triglycerides, wherein one or more of:

a) NE metabolites,

b) NE or NE metabolites: dopamine or dopamine metabolites,

c) NE and serotonin,

d) NE or NE metabolites and serotonin,

e) NE and serotonin metabolites,

f) NE or NE metabolites and serotonin metabolites, or

g) NE,

is/are greater than about 30% over normal level; or

dopamine or dopamine metabolites are less than about 30% below normal; or

fasting triglycerides are greater than about 150 mg/dl and/or said patient is suffering from hypertension.

2. The method of claim 1 , wherein said patient is further suffering from a condition selected from the group consisting of cardiovascular disease, Type 2 diabetes, pre-diabetes, Metabolic Syndrome, obesity, hyperglycemia, glucose intolerance, hyperinsulinemia, insulin resistance, elevated plasma lipid levels, and combinations thereof.

3. A method of treating a patient suffering from a metabolic condition, comprising the steps of:

(a) identifying patients to be treated by dopamine agonist therapy according to claim 1 , and

(b) administering to said identified patients a pharmaceutically effective regimen of dopamine agonist therapy;

wherein said metabolic condition is selected from the group consisting of cardiovascular disease, Type 2 diabetes, pre-diabetes, Metabolic Syndrome, obesity, hyperglycemia, glucose intolerance, hyperinsulinemia, insulin resistance, elevated plasma lipid levels, and combinations thereof.

4. The method of claim 2 , wherein said pharmaceutically effective regimen of dopamine agonist therapy comprises administration of bromocriptine.
