New diagnostic approach to central hypothyroidism after traumatic brain injury in children and adolescents
Authors' conclusion
The longer follow-up, valorization of clinical manifestations, nontraditional laboratory approach and therapeutic trial with levothyroxine in the present study revealed a higher rate of post-TBI CH in children and adolescents than that reported in the literature.
Study context
- Population
- Children and adolescents with a history of traumatic brain injury (TBI) with at least 1 year of follow-up
- Participants
- 31 children
- Outcome
- Long-term incidence of post-TBI central hypothyroidism (CH)
Methodological detailsEvaluated at hospital admission and every 3 months; CH diagnosis based on clinical and laboratory findings and a therapeutic trial with LT4
- Evaluated at hospital admission and every 3 months; CH diagnosis based on clinical and laboratory findings and a therapeutic trial with LT4
Main finding
As reported in the abstract
≥1 year of follow-up
Patients who developed CH
5
16%
CH with associated adrenal insufficiency
3
Observational data: associations, not effects.
Further findings
| Outcome | P value |
|---|---|
| FT4 at 3 and 12 months, CH vs no anterior pituitary dysfunction (n = 18)Median FT4 lower with CH | P = 0.01 |
Response to LT4 in CH
- Median FT4 increased (ng/dL)
- from 0.92 to 1.47
- Median IGF-1 increased (standard deviation scores (SDS))
- from −2.08 to −0.22
- Clinical resolution
Temporary suspension of LT4 in CH
- Median FT4 decreased (ng/dL)
- 1.02
- Median IGF-1 decreased (SDS)
- −1.07
- Clinical symptoms reappeared, resolved once LT4 reinitiated
