Anterior Pituitary Dysfunction in Survivors of Traumatic Brain Injury

Abstract

Recent data suggest that anterior pituitary dysfunction after traumatic brain injury (TBI) is common. We sought to confirm the results of earlier studies in a larger cohort of patients with dynamic testing of pituitary function. We studied 102 consecutive TBI survivors (85 males; median age 28, range 15-65 yr) who had survived severe or moderate TBI (initial Glasgow Coma Scale score 3-13) at a median of 17 months (range 6-36) post event. GH and ACTH reserves were initially assessed using the glucagon stimulation test (GST). Normative data on GH and cortisol responses to the GST were obtained from 31 matched healthy controls. Patients with subnormal GH or cortisol responses were further evaluated, using the insulin tolerance test (ITT) or arginine + GHRH test for GH assessment and the ITT or 250-microg short synacthen test for the assessment of ACTH reserve. Patients were considered to be GH or ACTH deficient if they failed both the GST and the second provocative test. Baseline thyroid function, prolactin, IGF-I, gonadotropins, testosterone, or estradiol was performed in all patients and compared with local reference ranges.In controls, normal response to the GST was a stimulated GH peak of greater than 5 microg/liter and cortisol peak greater than 450 nmol/liter (16 microg/dl). Eighteen TBI patients (17.6%) had GH response to the GST less than 5 microg/liter, 11 of whom also failed the ITT or the arginine + GHRH tests. GH-deficient patients had significantly higher body mass index (P = 0.003), and lower IGF-I concentrations (P < 0.001), than GH-sufficient patients. Twenty-three patients (22.5%) had cortisol responses to GST less than 450 nmol/liter, 13 of whom also failed the ITT or short synacthen test. GH or ACTH deficiencies were not related to age, Glasgow Coma Scale score, or the presence of other pituitary hormone abnormalities (P > 0.05). Twelve patients (11.8%) had gonadotropin and one (1%) had thyrotrophin deficiencies. Twelve patients (11.8%) had hyperprolactinemia. Twenty-nine patients (28.4%) had at least one anterior pituitary hormone deficiency. This is the largest study, to date, of hypopituitarism after TBI and confirms a high prevalence of undiagnosed anterior pituitary hormone abnormalities in survivors of TBI. Hypopituitarism is a treatable cause of morbidity after TBI. In addition to conventional pituitary hormone replacement, the potential of GH treatment to enhance recovery needs to be examined in a prospective study.

  • The paper relies on this without support.

    Normal GH and cortisol responses to the glucagon stimulation test are not well established.

    “Because normal GH and cortisol responses to the GST are not well established, we performed the GST in 31 healthy subjects (22 males) who were matched for age, sex, and body mass index (BMI) to the patient population.”

    This is the largest study to date of hypopituitarism after TBI.

    Under stressed conditions, such as intercurrent illness, mild untreated ACTH deficiency may become life threatening.

    “However, under stressed conditions, such as intercurrent illness, mild untreated ACTH deficiency may become life threatening.”

    No study in adults has compared the glucagon stimulation test with the arginine + GHRH test.

    “No study, in adults, has compared the GST with the arginine ϩ GHRH test.”
  • The authors state this as an assumption.

    The three patients without documented GCS scores were assumed to have a GCS of 13 or less because they were admitted to the intensive care unit.

    “The three remaining patients had no documented GCS scores but were admitted to the intensive care unit (ITU) and therefore were assumed to have a GCS of 13 or less.”
  • The paper relies on this without support.

    The GST has well-recognized false-fail results.

    “The discordance between the GST and ITT results in five of the 15 patients who failed the GST can be explained by the well-recognized false-fail results associated with the GST.”
  • The paper relies on this without support.

    Testosterone deficiency in males leads to reduced lean body mass and reduced bone mineral density; estrogen deficiency in females predisposes them to premature osteoporosis.

    The benefit of replacement of hormone deficiencies is well established.

    “Because hypopituitarism may impair recovery from TBI and because the benefit of replacement of hormone deficiencies is well established, identification of post-TBI hypopituitarism offers the potential to improve the chances of rehabilitation and enhance QoL.”
  • The paper relies on this without support.

    The study's patient sample was representative of survivors of TBI admitted to the study unit.

    “Although our patient sample was representative of survivors of TBI admitted to our unit, only a small number of our patients had long-term severe disability.”
  • The paper relies on this without support.

    Glucocorticoid deficiency can be life threatening, particularly in acutely ill patients, and may impair recovery and rehabilitation in the post-TBI period due to lethargy, muscle fatigue, and poor exercise capacity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Table 1 shows fewer GST responses below 3 than reported

    Minor

    The first 11 patients in Table 1 have GST responses below 3 g/liter. Of the remaining seven shown here, only patient 15 is below 3; patient 16 is reported as exactly 3. The table therefore shows 12, not 13, responses below the stated threshold.

  • BMI subgroup means imply different cohort-wide means

    Minor

    The Table 2 BMI means imply an overall mean of about 24.45 kg/m2 across 102 patients. The Table 5 means imply about 25.70 kg/m2 for the same 102 patients; rounding cannot account for the difference.

  • Hyperprolactinemia count differs for gonadotropin-deficient patients

    Minor

    The text says four gonadotropin-deficient patients had hyperprolactinemia, whereas Table 5 lists three.

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.

A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
