Brief Resume

Dr. Nazeeh Hanna has been a faculty member and Chief of Neonatology at Winthrop University Hospital since 2007. He is currently an Associate Professor of Pediatrics, State University of New York at Stony Brook. Following his medical education from Ain-Shams University in Egypt, he received his Pediatric training at Albany Medical Center and his Neonatal fellowship training at Brown University. Before joining Winthrop University Hospital, Dr. Hanna was Associate Professor of Pediatrics and the Co-Chief of Neonatology at UMDNJ-Robert Wood Johnson Medical School. Dr. Hanna is an established investigator who has international recognition for his work in reproductive immunology. His research track is focused in the area of developmental immunology and the potential impact of maternal exposure to environmental toxicants on preterm births. Dr. Hanna research interests were funded by several national agencies including NIH, NICHD, American Lung Association and National Institute of Environmental Health Sciences. Dr. Hanna has been an invited speaker or a Chair in National conferences on Neonatology and Reproductive Biology/Immunology. He is currently a member of several professional organizations including the American Academy of Pediatrics, Society for Pediatrics Research, American Pediatric Society, American Medical Association, Eastern Society for Pediatrics Research and American Society of Reproductive Immunology. He was selected as a member for the American Diabetes Association (ADA) Research Grant Review Committee as well ad hoc reviewer for several NIH study sections. Dr. Hanna serves on the Editorial Board of American Journal of Reproductive Immunology. In addition, he is a regular reviewer for several prestigious journals.

Description of Research Interests/Activities

Infants born prematurely are at increased risk of early postnatal and later developmental problems. Approximately 25% of premature babies less than 25 weeks have severe disabilities. Very premature infants who do not have severe disabilities are nevertheless at increased risk for cognitive, perceptual and behavioral problems. With advances in prenatal and neonatal care, there has been improvement in survival, but improvements in function and outcome have lagged. The optimal way to reduce complications of prematurity is to reduce the incidence of prematurity itself.
Dr. Hanna’s research interest focuses on evaluating altered immune function in pregnancy and preterm labor and the potential impact of maternal exposure to environmental toxicants on this disorder. The results of these studies will help bridge the gap between clinical and basic research and set the stage for future collaborative interdisciplinary studies. Dr. Hanna’s work elucidates the role of cytokines in fetal immune defense, namely interleukin-10 (IL-10) which is an anti-inflammatory agent produced by the placenta and plays an important role in the maintenance of normal pregnancy. IL-10 will counteract the harmful functions of the maternal immune cells, hence protecting the fetus. The overall hypothesis is that premature withdrawal of immunoregulatory molecules such as IL-10 will allow for increased expression of parturition inducing pro-inflammatory mediators and collagen degrading matrix metalloproteinases that may lead to preterm labor.
Dr. Hanna is currently directing several ongoing studies including characterization of the molecular mechanisms signaling IL-10 expression in gestational tissues, understanding the role of progesterone and prostaglandins in regulating the production of placenta cytokines, investigating the role of COX-2 inhibitors in preventing preterm labor, as well as elucidating environmental toxins-linked mechanisms of preterm labor. Dr. Hanna was recently awarded NIH grant titled: New Model Leading to Preterm Delivery: Role of Exposure to Environmental Toxins. The major goal of this project is to explore the interactions between inflammation and environmental toxins in preterm birth. In addition, using specific methodology, Dr. Hanna recently identified specific set of cytokines present in cervical secretions during pregnancy that help monitoring intrauterine inflammatory milieu in pregnancy. This methodology provides an easy, non-invasive way to monitor and understand intracervical immunity and its contribution to certain perinatal disease processes such as prematurity, intrauterine growth restriction, recurrent pregnancy loss, and preeclampsia.
The studies done at Winthrop University Hospital will contribute significantly to our understanding of the molecular pathogenesis of preterm labor and the role of exposure to environmental toxicants on this pathologic process. This work is exciting because it provides a novel model on the pathogenesis of preterm labor. As our understanding of mechanisms behind preterm labor and the role of inflammation grows, Dr. Hanna’s findings may ultimately suggest new strategies to predict, treat or prevent preterm labor.
