1. A method for the stimulation of bactericidal permeability increasing protein (BPI) in a subject'"'"'s tissue, comprising the step of administering to a subject infected with BPI sensitive bacteria a therapeutically effective amount of an eicosapentaenoic acid (EPA) analog, such that the subject'"'"'s tissues express increased levels of BPI to treat the BPI sensitive infection, wherein the EPA analog is selected from the group consisting of:
- wherein each P, independently, is a hydrogen atom and R is a hydrogen atom, an alkyl group or a pharmaceutically acceptable salt.
