transphenoidal surgery........noresponse-------use dopamin agonists-----still no responce-------octrotide------no responce------lastly radiotherapy....guide me if incorrect..thanks.

its correct.

let us give some detail about it......hypothalam secrete GHRH, this stimulate pituit to secrete GH and GH stimulate liver to produce IGF-1 which promote growth of bone , cartilage, muscle and other organs. At the same time hypothala secrete somatostatin which inhibit secretion of GH as regulatory
Excess growth hormone and IGF-1 in the blood cause most of the physical problems in acromegaly.
•Too much IGF-1 causes the bone growth that leads to changes in physical appearance and function.
•It causes thickening of soft tissues such as skin, tongue, and muscles. Enlargement of the tongue can lead to breathing problems and sleep apnea. Overgrowth of muscles can entrap nerves, causing pain syndromes such as carpal tunnel syndrome.
•Excess IGF-1 causes enlargement of organs such as the heart, which can result in heart failure and rhythm disorders.
•Excess growth hormone changes the way the body processes sugar and fats. This can cause diabetes and high levels of fats such as triglycerides in the blood. This in turn can lead to atherosclerosis and heart disease.
In more than 95% of cases of acromegaly, the excess growth hormone is produced by a tumor of the pituitary gland called adenoma.
•Secretion of growth hormone by a pituitary tumor is not controlled by the feedback loop. The end result is an excess of IGF-1, which causes abnormal tissue growth.
•They can, however, grow to considerable size and cause problems by pressing on and invading surrounding tissues.
Pt ususally come to office bec of headache or visual issues ....usually in their 40's 50s
complete PE
then you order routine testing based on PE results
CBC, BMP, LFT, FINGER STICK GLU, EKG, CXR,PRL, LIPID PROFILE , TSH, CT of head
GH, GHRH,IGF-1 LEVEL,cortisol,testo,lh,fsh,acth, bhcg if pt is female
if symptoms of arthritis, then order esr, ana, rf
SEND HOME TO SCHEDULE IN FEW DAY, during this time, you get all lab results and imaging.
when patient arrives, do focus Exam, if patient selected for surgery.
then admit to ward.
If patient taking thyroxine or hydrocortison keep taking medication
if pt taking ocp, stop them
if pt taking aspirin or ibuprofen stop 10 days before surgery, reschedule surgery
if pt taking aceta...continue

pt is very happy that dr sami treat him/her...and goes home well....

First treatment choice Transphenoidal surgery depending on size of tumor and Gh level
Tumor less than 10 mm or Gh less than 45 ng
If more we will give medical treatment to lower the size of pituitary and Gh level. Once level/ size achieved schedule for surgery. watch for adh hormone abnormalities after surgery..
Medical treatment for tumor size more than 10 mm or gh more than 45
doc is Somatostatin analogs (SSAs) are the first medication group used to treat acromegaly
so one injection once a month
second is GH receptor antagonists (GHRAs) once daily.
third is dopamine agonists are sometimes effective in patients who have mild degrees of excess GH and have both acromegaly and hyperprolactinemia
For those patients in which surgery could not remove whole tumor, people are not suitable for surgery, medical and surgical treatment have not relieved Acromegaly we use Radiotherapy. Watch for gradual decline of all pituitary hormones overtime with radiotherapy and supplement all hormone if the need be.
