The Glucagon Stimulation Test for Evaluation of Adult Growth Hormone Deficiency and Adrenocorticotropic Axis

Description

The purpose of this study is to find out if the Glucagon Stimulation Test (GST) is a reliable alternative to the Insulin Tolerance Test (ITT) for diagnosis of Growth Hormone Deficiency (GHD) and adrenal insufficiency. In some patients the accuracy of the GST for evaluation of adrenal insufficiency is compared to the adrenocorticotropin hormone (ACTH ) stimulation test.

Early Check: Expanded Screening in Newborns

Description

Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
