Types of Hormones

Types of Hormones

Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Types of Hormones

Types of Hormones

Hormones are classified into four main groups: steroids, eicosanoids, amino acid-based derivatives, and peptide hormones.
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...

Hormonal Regulation

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Plant Hormones

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Gene Therapy

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Summary

Low-dose hydrocortisone effectively reduces vasopressor needs and hospital stay for critically ill patients. Monitoring blood glucose and sodium is advised, but major side effects are uncommon with this hormone therapy.

Area of Science:

Critical Care Medicine
Endocrinology
Pharmacology

Background:

Hormone therapy is explored for critical illness, with varying results across agents.
Glucocorticoids, particularly hydrocortisone, show promise in managing specific intensive care unit (ICU) complications.

Purpose of the Study:

To review the efficacy and safety of various hormone therapies in critical care.
To focus on the role of glucocorticoids in improving outcomes for critically ill patients.

Main Methods:

Literature review and meta-analysis of studies investigating hormone treatments in critical illness.
Analysis of outcomes such as vasopressor requirements, length of stay, infection rates, and mortality.

Main Results:

Low-dose hydrocortisone decreases vasopressor use, shortens hospital stays, and may reduce pneumonia and ventilator time.
Oxandrolone is linked to shorter hospital stays and reduced weight loss.
Erythropoietin did not improve neurological outcomes in traumatic brain injury but showed mortality benefits in specific subgroups.

Conclusions:

Low-dose hydrocortisone is a beneficial hormone therapy in critical care, requiring monitoring of glycemia and natremia.
Other hormones like progesterone and erythropoietin have shown limited or specific benefits.
Glucocorticoids represent the most studied hormone class for critical care interventions.
