Definition

ACTH

alpha and beta MSH

Term
What stimulates and inhibits Growth Hormone secretion?
Definition

GHRH - stimulates

Somatostatin - inhibits

Term
What is the mechanism of Growth Hormone?
Definition
stimulates liver and other tissues to release IGF-1 via tyrosine kinase
Term
What are Anabolic and growth-promotng effects mediated through?
Definition
IGF-1 and IGF-2
Term
What can a deficiency of GH cause? Excess?
Definition

deficiency -> pituitary dwarfism

 

excess -> gigantism, Acromegaly

Term
How does glucose effect GH?
Definition

Hypoglycemia stimulates GH release

 

Hyperglycemia inhibits GH release

Term
What is the Negative Feedback for GH?
Definition

GH -> (-)Hypothalamus -X-> GHRH

 

IGF-1 -> (-)Anterior Pituitary -X-> GH

Term
What is the biggest producer of IGF-1?
Definition
Liver
Term
What are the Direct and Indirect actions of GH?
Definition

Direct:

Decrease insulin sensitivity

Increase lipolysis

Increase IGF-1

Increase protein syntesis

Increase epiphyseal growth

 

Indirect:

IGF-1 actions -> protein syntesis, epiphyseal growth

Term
What Endocrine drug is the same as human GH?
Definition
Somatropin (Serstim, Genotropin, Humatrope)
Term
What side effects are there in children and adults using GH?
Definition

Children:

leukemia, increase ICP, nausea

 

Adults:

carpal tunnel, peripheral edema, arthralgia, myalgia

Term
What can excess IGF-1 cause?
Definition
Acromegaly
Term
What are the Dopamine Receptor Agonists used for?
Definition

(Pergolide and Cabergoline)

 

Increase Dopamine -> Decreases prolactin -> Treat hyperprolactinemia from pituitary adenomas

Term

What are patients at risk for if they use gonadotropins?
Definition
Multiple pregnancies
Term
What is Oxytocin used for?
Definition
Facilitating birth, Breast feeding
Term
What does GnRH stimulate?
Definition
Stimulates FSH and LH release -> stimulate gonads Necessary for fertility
Term
What type of Synthetic GnRH is used to Diagnose pituitary vs. hypothalamic defect if a pt has hypogonadotropism?
Definition
Factrel
Term
What should be tried first with male infertility before turning to Lutrepulse?
Definition
Androgens
Term
What analogue of GnRH is used to treat prostate cancer?
Definition
Leuprolide
Term
How do the GnRH analogues work to treat prostate cancer?
Definition

(Leuprolide)

 

Initially increases LH production, then decreases LH and testosterone dramatically due to receptor down regulation

Term
What Endocrine drugs can be used to treat uterine fibroids?
Definition

Leuprolide

 

(Decreases estrogen - estrogen simulates growth)

Term
What is the GnRH Antagonist?
Definition
Ganirelix
Term
What drugs are used in in vitro fertilization?
Definition

(GnRH Antagonists)

 

Ganirelix

 

Used to delay LH surge -> delay ovulation to allow collection of ova

Post-menopausal woman

 

Definition

Post-menopausal woman

Menotropin (LH, FSH, and hCG)

Treat female infertility
