Long-term Follow-up of Pituitary and Hypothalamic Dysfunction in Children Who Have Suffered Moderate to Severe Head Trauma Included in the ENDOC TC Cohort (ENDOC TC 2)

May 20, 2026 updated by: Hospices Civils de Lyon

The annual incidence of traumatic brain injury (TBI), all causes combined, varies between 180 and 300 per 100,000. TBI increases the risk of death or serious sequelae by a factor of 8.

Studies conducted in adults have shown an anterior pituitary deficit in 28% to 68% of patients with TBI. The variability of these studies does not currently allow for standardization of the management of these children in either the acute or late phases.

Several studies, including a Lyon-based study called Endoc TC (Ref. Clinical Trials: NCT01250132), have aimed to investigate the association between anterior pituitary deficits in the acute phase and those identified a few months after the trauma.

Since then, few studies have been conducted more than five years after the trauma to study its pituitary consequences.

To date, the investigators have sought to study the long-term prevalence of pituitary and hypothalamic dysfunction in patients who suffered moderate to severe head trauma during childhood, specifically patients included in the initial Endoc TC study in Lyon.

To this end, the main objective is to determine the current height of these patients and whether there are any associated growth delays or other clinical signs that may suggest the presence of a pituitary or hypothalamic hormone deficiency.

This study consists of a telephone questionnaire lasting approximately 15 minutes, with participants from Lyon who took part in ENDOC TC study, designed to determine the growth of these patients and the presence or absence of symptoms that may be related to post-traumatic damage to the hypothalamic-pituitary system linked to head trauma.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Inclusion Criteria:

  • Consent of the child if under 18 years of age and no objection from both parents, or no objection from the adult patient

  • Patients included in the Princeps Endoc TC study in Lyon

    • Patients who have suffered a traumatic brain injury
    • Children aged 2 months to 16 years inclusive
    • Admitted to pediatric intensive care

Cohort of Children with Moderate-to-Severe Traumatic Brain Injury Admitted to Intensive Care
Patients who suffered moderate to severe head trauma during childhood requiring hospitalization in the intensive care unit at the Femme Mère Enfant hospital in Lyon, included in the Endoc TC study Telephone interview to obtain current measurements and endocrine symptoms. Extraction of data from initial Endoc TC study via Easily, secure patient software used by investigators' team.
Other: Telephone questionnaire
After receiving parental non-opposition for minor patients and non-opposition for adults patients, a structured telephone questionnaire is conducted. The interview is not recorded. It lasts approximately 15 minutes.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Final height difference in standard deviation (SD), relative to the genetic target height range
Time Frame: From Month 0 through Month 6

Final height difference corresponds to the child's current height, collected by telephone interview.

The genetic target height range is calculated using the following formula: (Father's Height + Mother's Height) ÷ 2 [+6.5 for boys/ -6.5 for girls]. The investigators will use the reference growth curves from the Center for Research in Epidemiology and Statistics (CRESS) to determine heights in SD.
From Month 0 through Month 6
