One of the primary objectives of the AFE Foundation is to advance research of amniotic fluid embolism (AFE) to better understand what causes an AFE. Through this understanding, we hope to establish more effective treatments, devise a mechanism for predictability, establish a gold standard diagnosis, and ultimately save the lives of mothers and their babies.
In 2012, the AFE Foundation joined into a formal collaboration with Baylor College of Medicine in Houston, Texas to establish the Amniotic Fluid Embolism Registry. The registry is a secure database of medical information, family history, and other related medical and non-medical information gleaned from medical records and interviews with patients and surviving family members. This comprehensive collection of information allows for a deeper understanding of individual cases of AFE and allows researchers the ability to gather vital information on the efficacy of treatments, and the reproductive and long-term health of survivors of AFE, and serves as a basis for clinical research.
In 2019, Wayne State University and the Perinatology Research Branch of the National Institute of Health (NIH) joined our research efforts and established a biorepository where samples of blood, tissue, cells, DNA, RNA, and protein from cases of AFE are stored and studied.
Our research efforts have gained international recognition. Our registry is the largest database of AFE cases ever amassed and has resulted in 11 abstracts and publications. These publications have been cited in over 150 other research papers spanning over 10 countries.
One of our most successful endeavors was helping establish a uniform diagnostic criteria to be used for research publication purposes. The intent is to help focus efforts on publications where all of the included cases meet the classic definition of AFE which includes the presence of hemodynamic and respiratory compromise accompanied by strictly defined disseminated intravascular coagulopathy. It is our hope that by limiting research reports involving amniotic fluid embolism to women who meet these criteria will enhance the validity of published data and assist in the identification of risk factors, effective treatments, and possibly useful biomarkers for this condition.
