Insights

CHARGE association can include hypogonadotrophic hypogonadism. This case highlights a rare instance of pituitary/hypothalamic hypoadrenalism in CHARGE syndrome, alongside 22q11 deletion overlap and cervical vertebral anomalies.

Area of Science:

  • Endocrinology
  • Genetics
  • Pediatric Medicine

Background:

  • Hypogonadotrophic hypogonadism is a recognized feature of CHARGE association.
  • Previous literature has not extensively documented broader pituitary dysfunction in CHARGE syndrome.

Observation:

  • A patient with CHARGE association presented with hypogonadotrophic hypogonadism.
  • Further evaluation revealed hypoadrenalism originating from the pituitary/hypothalamic axis.
  • The patient also exhibited features overlapping with 22q11 deletion syndrome and a unique cervical vertebral abnormality.

Findings:

  • This case expands the known spectrum of endocrine dysfunction in CHARGE association.
  • It demonstrates pituitary/hypothalamic hypoadrenalism as a potential, albeit rare, manifestation.
  • The co-occurrence of CHARGE, 22q11 deletion features, and cervical vertebral anomalies is noteworthy.

Implications:

  • Clinicians should consider comprehensive pituitary function testing in patients with CHARGE association.
  • This finding may refine diagnostic criteria and management strategies for CHARGE syndrome.
  • Further research is warranted to understand the genetic and clinical correlations between these overlapping syndromes.

Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.
Adrenal Gland Disorders01:27

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...
Hypertension II: Pathophysiology01:29

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
Hypothyroidism II: Pathophysiology01:23

Hypothyroidism II: Pathophysiology

Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
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...
Cushing Syndrome II: Pathophysiology01:19

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...
