Abstract

BACKGROUND: Hypopituitarism has been widely described in adults after traumatic brain injury (TBI); however, the available data in paediatric populations are scarce. Here, we report the results of a prospective, long-term study in children, adolescents and young adults. STUDY GROUP: Thirty-seven children (age, 2 months to 19·9 years) of 51 eligible patients were followed for 1 year. Clinical and baseline endocrine variables were assessed in all 3 and 12 months after TBI; children ≥ 6 years underwent two stimulation tests (glucagon stimulation and megatest). RESULTS: In the group ≥6 years, 11 of 23 patients (47·8%) had a subnormal GH peak 3 months after TBI that persisted in 8 of 23 patients (34%) after 1 year. The GH response showed no correlation with injury severity (GCS, Marshall classification). Growth velocity was normal in all patients, except for one. Body mass index (BMI) SDS increased significantly in the group with low GH response. A suboptimal cortisol was observed in 10 of 23 subjects, which normalized in all but three, 1 year thereafter. All patients but one showed a pubertal response to GnRH testing. No clinical or hormonal abnormalities were detectable in children <6 years. CONCLUSION: Our results recommend to prospectively follow children after TBI: firstly, because the impairment of pituitary function cannot be predicted, and secondly, to avoid the potential consequences of pituitary dysfunction. Prospective clinical trials are needed before recommending a systematic screening after TBI and/or GH therapy either in postpubertal children or in prepubertal children who grow normally.

    “Only one of 16 peripubertal children followed for one year after TBI failed to respond to GnRH testing [48].”
  • The lack of standardized diagnostic criteria and follow-up protocols has significantly contributed to the heterogeneity of findings on GHD after pediatric TBI.

    “The lack of standardized diagnostic criteria and follow-up protocols has significantly contributed to the heterogeneity of findings [6,29].”
  • In children, TBI severity has not shown any correlation with hormone deficiency rates.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
