This proposal represents a unique opportunity to combine epidemiologic and basic science methodologies to understand and improve upon important limitations in our ability to diagnose and treat a reproductive disorder with important public health consequences. Utilizing access to a large number of geographically, racially and ethnically diverse women at risk for EP, we plan to conduct a series of multicenter case control studies using well phenotyped bio-specimens, and ultimately conduct a prospective cohort study to assess actual use in the intended patient population. The development of non invasive methods of diagnosis, such as a serum test to diagnose an EP and/or miscarriage with high accuracy, would have tremendous clinical impact. We plan to develop a multiple marker bio-signature profile to aid in the diagnosis of EP. We hypothesize that a small number of markers, used in combination, will be able to distinguish an EP from IUP (combination of ongoing IUP and miscarriage) and/or can be used to distinguish a nonviable gestation (combination of EP and miscarriage) from an ongoing IUP. In Specific aim 1 we will develop, refine and validate a serum (multiple marker) test to identify EP based on putative markers of early implantation and viability. In Specific Aim 2 we will validate the potential of newly discovered biomarkers of EP to add to (or replace) those in our current multiple marker panel. In Specific aim 3 we will conduct an unbiased three-way proteomic discovery study that will identify new, lower abundance biomarker candidates that distinguish between EP, IUP and miscarriage.
