Research studies in adults have shown that certain hormones may be decreased or may not work normally which contributes to how sick a person becomes. The purpose of this project is to study hormones in children. The investigators will look to see if a decrease of certain hormone levels affects how sick a child may become. This study is intended to develop a connection between hormone levels and severity of illness. It is hoped that the information gathered will help develop further studies that may more clearly explain the role of hormones in critically ill children and possibly the introduction of hormone replacement in critical illness.

Critical Illness

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Defining the Prevalence of Acute Neuroendocrine Dysfunction and Correlating the Dysfunction With Outcomes in Critically Ill Pediatric Patients: A Pilot Study

Further study details as provided by Children's Healthcare of Atlanta:

Primary Outcome Measures:
  • To determine the prevalence of neuroendocrine dysfunction in critically ill pediatric patients. [ Time Frame: 13 months ]
    Conclued that neuroendocrine deficiency is present in critically ill pediatric patients. Prevalence is not greater in septic patients. Seventy-three children were enrolled over 13-month period. Larger scale studies are necessary to determine if presence of NEAD, or specific combinations of axis deficiency, is important in predicting outcomes or benefit of early hormonal replacement therapies in critically ill children.

Enrollment: 73
Study Start Date: August 2004
Study Completion Date: August 2007
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Detailed Description:

Neuroendocrine dysfunction is an abnormality in the production or release of certain hormones. Studies completed in adult patients have shown abnormal hormone levels in critical illness can contribute to how long patients stay in the intensive care unit, how severe their illness is and whether or not they survive. In children hormones are produced differently and have different functions. Depending on the particular illness in question hormonal dysfunction may have grave clinical consequences.

Thus far, there have been few studies that have examined neuroendocrine dysfunction in children. The aim of our study is to identify the common hormone responses in children, and to identify any connection between hormone levels and outcomes (likelihood of child staying in the intensive care unit for multiple days, etc.).

To explore these aims we will draw blood from all critically ill patients admitted to the pediatric intensive care unit (PICU) and check various hormone levels. Only those patients who require blood samples as part of their admission will have blood tests for certain hormone levels. No change will be made from established standard of care for a patient's particular critical illness.

The study is designed to examine hormone responses to critical illness and identify a connection between hormone levels and severity of illness. Based on these lab values we intend to lay a foundation for further studies that may more clearly explain the role of hormones in critically ill children, and possibly the introduction of hormone replacement in critical illness.
