Overview
Treatment involves appropriate hormone replacement therapy that results in complete recovery and reversal of symptoms.
Medical Therapy
- Treatment involves appropriate hormone replacement therapy, which must be taken for the rest of your life that results in significant improvement and reversal of not only the physical symptoms but also the psychological symptoms.[1][2][3][4][5][6][7][8][9][10][11][12]
ACTH deficiency:
- Cortisol deficiency is replaced with 15-25mg of hydrocortisone per day with increased doses in patients with severe deficiency, increased body weight and in times of surgery, illness, procedures and other stresses.
- Unfortunately, there is no established test to assess adequate hormonal replacement. Plasma ACTH measurement and serum/salivary/urinary cortisol values are all unreliable. So assessment of adequate hormonal replacement is based on clinical basis with Cushingoid features showing excessive replacement while symptoms of adrenal insufficiency suggesting insufficient hormonal replacement.
- Glucocorticoid relacement can cause polyuria due to unmasking of underlying central diabetes insipidus.
- Mineralocorticoids are rarely required as aldosterone secretion is primarily regulated by angiotensin II and potassium not by ACTH.
TSH deficiency:
- In patients with combined hypothyroidism and hypocortisolism, glucocorticoids (physiologic doses and increased doses in stress) are replaced first than thyroid hormone replacement because treating the hypothyroidism alone by levothyroxine can worsen the severity of cortisol deficiency by increasing the clearance of cortisol. So, it is important to assess adrenal function first including corticotropin (ACTH) reserve before adminstering T4 (levothyroxine).
- T4 (Levothyroxine) replacement therapy is usually started with weight-based T4 dose of 1.6 mcg/kg.
- American Thyroid Association (ATA) recommends dose adjustment to keep serum free T4 concentration in upper half of reference range.
- Pregnancy can be made possible by giving exogenous gonadotropins or pulsatile GnRH. Androgens can be given to females having low libido.[13]
- DDAVP is the treatment of choice for patients with DI.[14]
- GH is replaced on case to case basis starting with a low dose(0.1-0.3mg/day) and titrated upwards by 0.1mg/d/month with repeated measurement of hormone levels every month initially for the first 6 months followed by yearly measurements and is replaced once all other hormones have been replaced.[15]
