Endocrine dysfunction following traumatic brain injury in children

Area of Science:

• Pediatric Endocrinology
• Pediatric Neurology
• Neuroendocrinology

Background:

• Traumatic brain injury (TBI) can disrupt hormonal regulation.
• Endocrine dysfunction is a potential complication following pediatric TBI.

Purpose of the Study:

• To determine the incidence of endocrine dysfunction in children after TBI.
• To evaluate the temporal pattern and types of endocrine abnormalities post-TBI.

Main Methods:

• Prospective study of 31 children (age 1.5-18 years) with TBI (Glasgow Coma Scale ≤ 12).
• Hormonal assessments (thyroid, IGF-1, IGFBP-3, cortisol, prolactin, growth hormone) at multiple time points (1, 3, 6, 12 months).
• Specific tests included overnight growth hormone secretion and adrenal reserve at 6 months.

Main Results:

• High incidence of endocrine dysfunction observed: 15% at 1 month, 75% at 6 months, and 29% at 12 months.
• At 12 months, specific dysfunctions included precocious puberty (14%), hypothyroidism (9%), and growth hormone deficiency (5%).
• Injury severity did not correlate with endocrine dysfunction at 1 year.

Conclusions:

• Endocrine dysfunction is frequent in children post-TBI, with a peak incidence at 6 months.
• Most endocrine issues resolve within one year.
• Recommend endocrine surveillance at 6 and 12 months after moderate to severe TBI for timely intervention.
