Insights

Secondary adrenal insufficiency (AI) is common in children after traumatic brain injury (TBI). This condition, particularly when intracranial hypertension is present, requires systematic pituitary function assessment and may necessitate hormonal replacement therapy.

Area of Science:

  • Pediatric Intensive Care
  • Neuroendocrinology
  • Trauma Management

Background:

  • Secondary adrenal insufficiency (AI) is increasingly recognized post-traumatic brain injury (TBI).
  • Adult studies suggest AI can occur acutely after TBI, impacting patient management.
  • Pediatric TBI patients may be at risk for acute AI.

Purpose of the Study:

  • To determine the prevalence and characteristics of AI in the acute phase of pediatric TBI.
  • To investigate the association between AI and TBI severity markers.

Main Methods:

  • Systematic evaluation of adrenal function in pediatric TBI patients admitted to the ICU.
  • Serial cortisol and adrenocorticotropic hormone (ACTH) measurements were collected post-admission.
  • AI defined by specific cortisol and ACTH levels.

Main Results:

  • Secondary AI was identified in 36% of evaluated pediatric TBI patients.
  • AI was significantly more frequent in patients with intracranial hypertension.
  • AI was associated with longer mechanical ventilation duration.

Conclusions:

  • Secondary AI is a frequent complication during the acute phase of pediatric TBI.
  • Intracranial hypertension is a key factor associated with AI in these patients.
  • Systematic pituitary function assessment and consideration of hormonal replacement are crucial.

Adrenal Gland Disorders

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
Cushing Syndrome I: Introduction01:26

Cushing Syndrome I: Introduction

Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
