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...
Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining, normally used to...

Structures of the Endocrine System00:59

Structures of the Endocrine System

The intricate framework of the endocrine system encompasses a diverse array of glands, with their target tissues and organs strategically distributed throughout the body. Central to this network are the endocrine glands, specialized structures that lack ducts and release hormones directly into the interstitial fluid. Notably, the hypothalamus, a vital neuroendocrine organ situated in the brain, governs neural functions and serves as a potent source of hormonal regulation. Near the hypothalamus...
The Endocrine System01:29

The Endocrine System

The endocrine system is an extensive network of glands – organs or tissues in the body that create chemicals that control many bodily functions, that secrete hormones, which are chemical messengers that play essential roles in regulating various bodily functions. These hormones are secreted into the bloodstream and travel throughout the body. They require specific receptors to convey signals to cells possessing these corresponding receptors. This complex signaling mechanism ensures that every...
Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...

Summary
This summary is machine-generated.

Systemic amyloidosis frequently impacts the endocrine system, causing dysfunction, particularly in the thyroid and testes. Early recognition of adrenal or gonadal issues is crucial for timely diagnosis and management.

Area of Science:

  • Endocrinology
  • Nephrology
  • Internal Medicine

Background:

  • Systemic amyloidosis is a rare condition characterized by amyloid protein deposition in organs.
  • Endocrine involvement is increasingly recognized but often underdiagnosed.
  • Distinguishing systemic from local amyloidosis is critical for appropriate management.

Purpose of the Study:

  • To review and summarize existing literature on endocrine system involvement in systemic amyloidosis.
  • To highlight the prevalence and clinical significance of endocrine dysfunction in affected patients.
  • To clarify the diagnostic role of amyloid detection in specific endocrine glands.

Main Methods:

  • Comprehensive literature review of MEDLINE database.
  • Inclusion of clinical trials, in vitro studies, and case reports.
  • Focus on pituitary, thyroid, parathyroid, pancreatic, adrenal, and gonadal systems.

Main Results:

  • Systemic amyloidosis primarily affects the thyroid and testes, leading to functional impairment.
  • Adrenal insufficiency due to amyloid infiltration is a life-threatening condition requiring prompt evaluation.
  • Amyloid deposition in the pituitary and pancreas is typically local, not systemic.

Conclusions:

  • Systemic amyloidosis frequently involves the endocrine system, with dysfunction being more common than previously assumed.
  • Clinical signs like rapid goiter or adrenal/gonadal dysfunction warrant suspicion of amyloid infiltration.
  • Further large-scale studies are needed to fully characterize endocrine involvement and guide clinical practice.
