UMDNJ-Robert
Wood Johnson Medical School Kernicterus Research and Prevention Center
There has been recent concern in the United States over increased reports
of kernicterus. Kernicterus is a preventable disability that results from
brain damage caused by severe levels of jaundice. Symptoms of kernicterus
include athetoid cerebral palsy, sensorineural hearing loss, gaze paresis,
dental dysplasia, and mental retardation.
Kernicterus is easily prevented. Jaundice can be reduced to safe levels
with appropriate treatment such as phototherapy or an exchange transfusion.
One objective of Healthy People 2010 is to reduce or eliminate preventable
neurodevelopmental disability in infancy. The Centers for Disease Control
and Prevention (CDC) is funding the development of kernicterus research and
prevention programs. Two centers have been funded; one is in New Jersey and
the other is in Pennsylvania.
The UMDNJ-Robert Wood Johnson Medical School Kernicterus Research and
Prevention Center, New Brunswick, New Jersey will conduct the following
projects:
Monitoring Activities
The incidence of kernicterus and severe hyperbilirubinemia in neonates in
the United States is not known because, to date, these conditions have not
been routinely followed in this population.
The New Jersey center, along with the New Jersey Department of Health and
Senior Services, will develop and implement a monitoring system to track
and analyze new cases of kernicterus and severe hyperbilirubinemia, defined
as total bilirubin level during the neonatal period of > 20 mg/dl. The area
to be served by this program includes the entire state of New Jersey.
Preliminary research on infants born from 1992 through 2001revealed 82
kernicterus cases, with 7.5 cases for each 100,000 live births. There was
significant variation in rates by race and ethnicity. The lowest rate was
among Hispanics and the highest among Asians.
Epidemiologic
Study
The main goal of this project is to track cases of severe
hyperbilirubinemia and kernicterus in order to identify risk factors and
ways to prevent these conditions.
The New Jersey center will study the epidemiology of kernicterus morbidity
and mortality by using available national and regional databases. All
infants with kernicterus in New Jersey from 1992 through 2004 will be
looked at using maternal, neonatal, and infant medical records, as well as
a survey of parents. The same methods will also be applied to study new
cases of severe hyperbilirubinemia.
Special Projects
Kernicterus is a major public health concern because it causes permanent
brain damage and impairs a child’s quality of life. The New Jersey
kernicterus research and prevention center will establish kernicterus
education programs for medical students, fellows, primary care physicians,
and parents. In addition, a support program for families of children who
have kernicterus will be organized.
Sharing Information
The New Jersey center plans to train nurses, physicians, educators, and
other health care providers to enhance the awareness of risk factors for
neonatal hyperbilirubinemia. Information will be shared through mailings to
parents, support groups, and the media; scientific publications and
presentations at professional conferences will also be provided.
