Abstract

Objectives Childhood traumatic brain injury (TBI) is a public health issue. Our objectives were to determine the prevalence of permanent pituitary hormone deficiency and to detect the emergence of other pituitary dysfunctions or central precocious puberty several years after severe TBI. Design Follow-up at least 5 years post severe TBI of a prospective longitudinal study. Patients Overall, 66/87 children, who had endocrine evaluation 1 year post severe TBI, were included (24 with pituitary dysfunction 1 year post TBI). Main outcome measures In all children, the pituitary hormones basal levels were assessed at least 5 years post TBI. Growth hormone (GH) stimulation tests were performed 3-4 years post TBI in children with GH deficiency (GHD) 1 year post TBI and in all children with low height velocity (<-1 DS) or low IGF-1 (<-2 DS). Central precocious puberty (CPP) was confirmed by GnRH stimulation test. Results Overall, 61/66 children were followed up 7 (5-10) years post TBI (median; (range)); 17/61 children had GHD 1 year post TBI, and GHD was confirmed in 5/17 patients. For one boy, with normal pituitary function 1 year post TBI, GHD was diagnosed 6.5 years post TBI. 4/61 patients developed CPP, 5.7 (2.4-6.1) years post-TBI. Having a pituitary dysfunction 1 year post TBI was significantly associated with pituitary dysfunction or CPP more than 5 years post TBI. Conclusion Severe TBI in childhood can lead to permanent pituitary dysfunction; GHD and CPP may appear after many years. We recommend systematic hormonal assessment in children 1 year after severe TBI and a prolonged monitoring of growth and pubertal maturation. Recommendations should be elaborated for the families and treating physicians.

  • Studies indicate that the majority of children diagnosed with TBI-related GHD show onset of symptoms between 6 months and 2 years post-injury, with some cases taking longer.

    “Studies indicate that the majority of children diagnosed with TBI-related GHD show onset of symptoms between 6 months and 2 years post-injury, with some cases taking longer to manifest [24,25,26,27].”
  • Longitudinal follow-up studies indicate that GH secretion may normalize within 1 to 2 years after injury in some children, especially when the initial injury was less severe and no major structural damage to the HPA occurred.

    “Longitudinal follow-up studies have indicated that GH secretion may normalize within 1 to 2 years after the injury in some children, especially when the initial injury was less severe and no major structural damage to the HPA occurred [24,27].”
  • Dassa et al. reported GHD in 17 of 61 children one year after TBI, with one case diagnosed 6.5 years post-injury.

    “In another study, Dassa et al. reported GHD in 17 of 61 children one year after TBI, with one case diagnosed 6.5 years post-injury [27].”
  • Research suggests that persistence of GHD beyond two years is more common in cases of significant hypothalamic or pituitary trauma.

    “Research suggests that the persistence of GHD beyond two years is more common in cases of significant hypothalamic or pituitary trauma [24,27].”
  • The presence of pituitary dysfunction one year after TBI was significantly associated with increased likelihood of persistent pituitary abnormalities or subsequent CPP more than five years after the initial trauma.

    “Importantly, the presence of pituitary dysfunction one year after TBI was significantly associated with increased likelihood of persistent pituitary abnormalities or subsequent CPP more than five years after the initial trauma [6,27].”

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.
