Without adequate steroid replacement therapy, this was .. who is medically unstable.3 Serum cortisol, ACTH, aldo- .. Plasma cortisol levels before and. Another patient treated with both types of hormone therapy in tandem, . Baseline serum cortisol levels (as well as serum ACTH levels for most. Unlike in Addison disease, hyperpigmentation does not occur and serum sodium and potassium levels are relatively normal. ACTH and cortisol levels both are.
However, the previous results are not confirmed by other studies 54 Additionally, an association of GCs use and the risk for atrial fibrillation and flutter has been established by several studies 56 - An interesting review of the existing literature published between shows that GC-induced hyperglycemia is common among patients with and without diabetes mellitus.
The OR for new onset diabetes mellitus ranges from 1. This is confirmed by several studies. Furthermore, there was a dose related relationship between prednisone use and pneumonia risk in RA The latter results were confirmed by additional studies that have identified GCs as an independent risk factor for infections 63 Also, caution about GC use in patients with active or dormant TB is well accepted as these individuals are susceptible to contract or to sustain activation of the disease An epidemiological study of patients with TB showed that they were nearly 5 times more likely to have been using GCs at the time of their diagnosis Systemic effects include a reduction in calcium absorption from the intestine and a reduction in calcium reabsorption in the kidney, both enhancing PTH secretion and thus bone loss.
Furthermore, the attenuation of sex steroids and growth hormone by GCs enhances bone loss. The direct effects of GCs on bone cells include induction of osteoblast and osteocyte apoptosis through activation of pro-apoptotic molecules, impairment of Wnt signaling, and induction of RANKL, a potent stimulator of osteoclastogenesis produced by osteoblasts As a result, GCs induced osteoporosis is the most common type of iatrogenic osteoporosis.
This has been confirmed by several studies.
One of them showed that therapy with high-dose oral GCs caused significant decrease in BMD even in the first 2 months of therapy Intermittent high-dose regimens with cumulative doses less than 1gr, however, did not show an increased risk.
Risk declines rapidly, the decrease beginning 3 months after cessation of therapy For additional details please see the Endotext chapter on Glucocorticoid-induced osteoporosis These disturbances can be detected by structural, functional, and spectroscopic imaging. Behavioral changes in feeding and sleeping are commonly observed. Among psychic AEs, hypomania and mania are the most common during acute GC therapy and depression during long-term treatment.
Suicides have also been reported Cognitive changes affect mostly declarative and working memory. There has to be greater concern for pediatric patients.

Several medications such as lithium, phenytoin, lamotrigine, memantine and other anti-seizure, anti-psychotics, and anti-depressants could be useful for treating such disorders 77 GCs exert multiple growth suppressing effects, such as inhibition of GH secretion and IGF-1 expression, reduction of bone and collagen formation, bone mineralization, and vascularization.
These effects are more pronounced with daily oral GCs than alternate day oral GC therapy According to a study of children with cystic fibrosis who have received alternate day treatment with prednisone, boys but not girls, had persistent growth impairment mean final height 4cm less than children who were treated with placebo after discontinuation of treatment Apart from growth retardation, children may also be more susceptible to other AEs associated with GCs such as osteoporosis, glaucoma and cataracts.
Moreover, fracture risk seems to be higher in GC-treated children Intrauterine exposure to GCs is able to affect fetal HPA axis development causing reduction in fetal and, in some cases newborn and infant HPA axis activity under basal conditions and more consistently after pain-related stress. Although baseline HPA axis function seems to recover within the first 2 weeks postpartum, there is initial evidence that blunted HPA axis reactivity to pain-related stress persists throughout the first 4 months of life.
Moreover, exposure to GCs during pregnancy has been linked to impaired fetal growth and modulated fetal immune functions, indicators of compromised cognitive, neurological and psychological functions, and increased blood pressure into adolescence.
It is also unknown if the risk of adrenal insufficiency is increased, if the alternative hormone therapy is used after the first hormone therapy, either when one is used immediately after the other i. Given the uncertainty of adrenal insufficiency following hormone therapy for infantile spasms, and a personal experience of clinical adrenal insufficiency following corticosteroid therapy in a patient with infantile spasms 18our guideline initially included a post-hormone endocrinologist-guided laboratory evaluation of adrenal function.
Here, we report our experience with monitoring of adrenal function following hormone therapy for infantile spasms as well as the occurrence of clinical adrenal insufficiency.
The medical records of patients were assessed for hormone treatments, adrenal function testing, and clinical signs of post-treatment adrenal insufficiency. The goal of this study was to determine the frequency of decreased adrenal reserve or signs of clinical adrenal insufficiency in infantile spasms patients treated with hormone therapy.
Our management guideline emphasizes the initial treatment with first-line therapies which at our program include ACTH, oral prednisolone, and vigabatrin. After physician-guided counseling, caregivers and clinicians work together to choose the desired treatment.

Given that some patients who fail to respond to ACTH will respond to oral corticosteroids, and vice versa 4some patients in this study received the alternative hormone therapy immediately after the first hormone therapy was deemed ineffective. Some patients received vigabatrin in between hormone therapies depending on the preferences for treatment.
Assessment of the Hypothalamic—Pituitary—Adrenal Axis From September to Julyour infantile spasms management guideline included a recommendation for an endocrinologist-guided laboratory assessment of adrenal function after completion of hormone therapy. Given the relatively low yield of this testing and the lack of clinical signs of adrenal insufficiency with laboratory testing in 14 patients, we subsequently discontinued these evaluations and instead relied upon clinical signs of adrenal insufficiency.
A laboratory assessment of adrenal function included an a. The ACTH stimulation test was chosen more frequently than the glucagon stimulation test given that the former is of shorter duration.
For both tests, a fasting state is not required. Baseline serum cortisol levels as well as serum ACTH levels for most patients were drawn upon placement of a peripheral indwelling intravenous line, which were then maintained by means of a heparin-lock needle. For glucagon stimulation testing, glucagon Glucagen-Bedford Laboratories at 0.
Blood samples for serum glucose and cortisol were obtained at 60, 90,and min after glucagon administration. Blood samples were obtained at 20 and 40 min for the measurement of serum cortisol. Serum cortisol was measured using chemiluminescent enzyme immunoassay by our institution laboratory. Statistics We use descriptive statistics as well as median, mean, and range where appropriate. Given the study design a retrospective medical record reviewa waiver of written or verbal consent was granted by the Institutional Review Board.
The authors have no conflicts of interest related to this research. Results During the study period, 59 patients with infantile spasms were referred to our Infantile Spasms Program. The effects of too much adrenocorticotropic hormone are mainly due to the increase in cortisol levels which result. Higher than normal levels of adrenocorticotropic hormone may be due to: Cushing's disease — this is the most common cause of increased adrenocorticotropic hormone.
It is caused by a non-cancerous tumour called an adenoma located in the pituitary gland, which produces excess amounts of adrenocorticotropic hormone. A tumour, outside the pituitary gland, producing adrenocorticotropic hormone also called ectopic adrenocorticotropic hormone tumour. Addison's disease although cortisol levels are low, adrenocorticotropic hormone levels are raised.
Congenital adrenal hyperplasia a genetic disorder with inadequate production of cortisol, aldosterone or both. What happens if I have too little adrenocorticotropic hormone? Lower than normal levels of adrenocorticotropic hormone may be due to: Cushing's syndrome related to an adrenal tumour. Cushing's syndrome due to steroid medication.
