Dr. Refaai's clinical service is in Transfusion Medicine with subspecialty involvement in laboratory coagulation/thrombosis testing.

Qualifications

M.D., Aleppo University School of Medicine, Syria 1993
Resident in Clinical Pathology, Barnes-Jewish Hospital, Washington University 2003-06

Research Overview

Dr. Refaai's recent studies have included:

Analysis of fatty acid ethyl ester (FAEE) concentrations in binge drinking, chronic alcoholics, and postmortem biopsies. FAEE are non-oxidative ethanol metabolites. Studies of qualitative and quantitative variations of FAEE in rats' plasma and tissue from different organs. Rats have been studied before, during, and after alcohol exposure.

Comparison of tissue factor pathway inhibitor (TFPI) concentration and activity in mononuclear cells from normal individuals versus patients with Paroxysmal Nocturnal Hemoglobinuria. Comparison of TFPI concentrations in normal mouse plasma and endothelial cells versus a diabetic mouse model.

Generation of a polyclonal human protein Z (HPZ) ELISA assay to measure HPZ concentrations in patients with thrombosis disorders.
