Mayo Clinic Q and A: Understanding adrenal insufficiency - Mayo Clinic News Network
Patients receiving long-term glucocorticoid treatment are at risk of developing adrenal insufficiency during treatment. Adrenocorticotrophic hormone ACTH concentrations were generally low and anti-adrenal antibodies were negative indicating secondary adrenal insufficiency as the most likely diagnosis. Adrenal function did not depend on sex or seropositivity of rheumatoid arthritis. We demonstrate a high prevalence of adrenal insufficiency during ongoing low-dose prednisolone treatment.
The results urge to increase focus on the condition to ensure identification and correct management of insufficient patients during stress and withdrawal. Strategies for adrenal function evaluation during ongoing low-dose glucocorticoid treatment need to be established. Glucocorticoids are used in the treatment of a variety of inflammatory and autoimmune diseases, seldom with any doubt about the clinical indication and effect, but often with many side effects.
Glucocorticoid-induced adrenal insufficiency is a potentially life-threatening side effect as it renders the patient unable to produce an adequate cortisol response to stress. Clinically relevant hypocortisolism can occur after withdrawal from glucocorticoid treatment, but also during ongoing treatment if there is a mismatch between glucocorticoid requirements to overcome stress and the sum of the endogenous cortisol production capacity and exogenous glucocorticoid intake.
High-dose prednisolone treatment often ensures sufficient glucocorticoid intake to overcome most stressful situations, but low-dose prednisolone treatment might not. If the adrenal function is suppressed these patients are thus not sufficiently covered during stress by the prednisolone treatment itself.
Glucocorticoid-induced adrenal insufficiency is probably underestimated in clinical practice 34. In rheumatoid arthritis, low-dose prednisolone treatment for 2 years in addition to disease-modifying anti-rheumatic drugs reduces joint destruction and increases disease remission 5and is thus widely used both as initial, but also maintenance therapy 67.
It is currently not recommended to evaluate adrenal function routinely during the course of glucocorticoid treatment 8which potentially leaves a large group of patients with long-lasting adrenal insufficiency, who are not adequately informed about the risk and treatment of adrenal insufficiency during intercurrent stress.
Patients with rheumatoid arthritis were retrieved from four rheumatology departments located in the greater Copenhagen area in Denmark. The diagnosis of rheumatoid arthritis was based on the American Rheumatism Association classification 9. In total consecutive patients were identified.
The patients were recruited as part of a larger study ClinicalTrials. Nbiband were screened for four specific polymorphisms of the glucocorticoid receptor gene NR3C1 and grouped accordingly before being invited to a Synacthen test. In total, 42 patients underwent assessment of adrenal function. Disease history and data on history of treatment with prednisolone and other glucocorticoid containing formulations were obtained from medical records and confirmed by patient interview.
The protocol was approved by the local Ethics Committee J. H and the Data Protection Agency J. All participants gave written informed consent before enrolment. After the Synacthen test patients continued the prednisolone treatment. Samples were analyzed in few series.
Cut-off for normal cortisol response to the Synacthen test was validated locally for the new assay 11 and defined as the 25th percentile — 1. Plasma concentrations of adrenocorticotrophic hormone ACTH and anti-adrenal antibodies were measured at baseline to distinguish patients with primary autoimmune adrenal insufficiency.
Briefly, one drop of patient sample diluted in phosphate-buffered saline PBS was applied to each well on substrate slides. A sample was considered positive if the specific staining was observed to be greater than a negative control.
Ninety-five percent confidence intervals for proportions were calculated by the Wilson Score interval formula. Comparison between groups was made by independent t -test for normally distributed continuous data and Chi-square test for categorical data, since data were equally distributed among cells. All statistical analyses were performed by SAS version 9. Patients in the study were generally younger mean age 65 years s.
The characteristics of the study population at the time of the Synacthen test are shown in Table 1. The 42 patients had been treated with prednisolone for a median of 66 months range: 6— months.

Higher occurrence was observed in the total cohort, which also included patients who had received concomitant treatment with other glucocorticoid formulas.
Glucocorticoid-induced adrenal insufficiency is often believed to occur in patients who have been treated with more than the equivalent of 7.
We here show that glucocorticoid-induced adrenal insufficiency is also a problem during ongoing low-dose prednisolone treatment. This was chosen to investigate the prevalence of adrenal insufficiency during ongoing prednisolone treatment in the particular situation, where the prednisolone dose is too low to cover extra needs during stress.
Adrenal insufficiency can occur after all locally applied glucocorticoids 417and high prevalence has especially been demonstrated after intra-articular glucocorticoid injections 418192021 and in patients using multiple glucocorticoid forms concomitantly 4.
Adrenal suppression after a single intra-articular glucocorticoid injection has been shown to last up to 4 weeks 1920 Six patients had received higher doses at some point within the 6 months before the Synacthen test. The patient cohort was representative of patients with rheumatoid arthritis in low-dose prednisolone treatment where variations in disease activity lead to short periods of increased prednisolone dose or intra-articular or -muscular corticosteroid injections.
Likewise, the cohort is comparable to other patient populations in glucocorticoid treatment where increased disease activity is treated with increased glucocorticoid intake increased dose or additional formula.
Our findings are similar to studies of patients receiving more varying 22 or slightly higher glucocorticoid doses 23 We found no association between adrenal function and duration of prednisolone treatment. However, it is possible that such an association would be clearer for shorter durations than we have investigated in the present study.
The risk of adrenal insufficiency generally increases with increased duration of glucocorticoid treatment 424but glucocorticoid-induced adrenal suppression is at the same time associated with a substantial individual variation with less strong association to glucocorticoid dose or duration of treatment 322 The study has confirmed a strong suspicion that adrenal insufficiency is highly prevalent during ongoing low-dose prednisolone treatment, which was the aim of the study.
As patients already suffered from one autoimmune disease rheumatoid arthritis we aimed at excluding primary adrenal insufficiency. Since ACTH concentrations were generally low and anti-adrenal antibodies were negative this was very unlikely, and the diagnosis of secondary, glucocorticoid-induced adrenal insufficiency was considered accurate. For reliable assessment of adrenal function, it is generally agreed that a stimulation test is necessary 32627 The low-dose test has been found to be more sensitive in detecting mild adrenal insufficiency as the stimulation is at a more physiological level 3132but technical details can influence its accuracy, resulting in reduced specificity 3234 There is no published consensus on which test is preferred.
P-cortisol measurement was performed with a new generation assay, the Roche Elecsys Cortisol II assay, performing more specific and thus lower cortisol measurements than the older Roche Elecsys Cortisol assay. All cortisol samples were frozen and analyzed in few series. Local assay-specific cut-off for normal adrenal function was validated for the new assay 11 based on Synacthen tests performed in previously described healthy controls 12minimizing the risk of methodological bias.
The prednisolone pause of mean The reported prevalence in this study may be surprising to clinicians who could argue that symptomatic patients would nevertheless be identified. However, in a meta-analysis only 10 of 98 patients with glucocorticoid-induced adrenal insufficiency reported symptoms of adrenal insufficiency, concluding that the diagnosis would have been missed in 88 patients if only symptomatic patients underwent assessment of adrenal function 4.
Adrenal insufficiency most often presents with very unspecific symptoms. Patients may present with symptoms such as fatigue, loss of energy, muscle and joint pain which could result from increased disease activity of rheumatoid arthritis, but could as well relate to adrenal insufficiency. Adrenal insufficiency should especially be suspected when other signs and symptoms of disease activity of the rheumatoid arthritis C-reactive protein, joint swelling, etc.
It is a general clinical observation that prednisolone tapering is very difficult in many patients with rheumatoid arthritis and other rheumatologic diseases Two patients in our study had failed attempts to taper the prednisolone dose shortly before enrolment in the study.
Both of these patients were found to have adrenal insufficiency. During the h prednisolone pause before the study Synacthen test several patients experienced an increase in muscle and joint pain and some felt generally unwell. Although not systematically registered it was a clinical observation that there was a connection between having notable symptoms during the prednisolone pause and a reduced response to the Synacthen test.
All patients were informed to contact the department or simply resume prednisolone and postpone the Synacthen test if they felt unwell, but none chose this option. Also signs and symptoms of an acute adrenal crisis are mostly unspecific and can be confused with an exacerbation of the underlying disease or symptoms of the triggering stressful event such as gastroenteritis or influenza-like illnesses.
Thus, there is a high risk of misclassification of adrenal crises in glucocorticoid-treated patients without verified adrenal insufficiency and retrospective studies investigating the incidence of glucocorticoid-induced adrenal crises cannot account for all the dark numbers of incorrectly classified and coded crises The incidence of glucocorticoid-induced adrenal crisis is thus difficult to clarify.
In 28 patients with an established diagnosis of glucocorticoid-induced adrenal insufficiency the reported incidence of adrenal crises was 15 per patient-years This was higher than the incidence of 5. Similar, a prospective study has reported an incidence of 8.
Overall, these data suggest that adrenal crisis can occur in patients during ongoing low-dose prednisolone treatment who have severely suppressed adrenal function. Our results call for increased focus on the adrenal function during long-term low-dose prednisolone treatment.
We argue that all patients receiving glucocorticoid treatment should be informed about the risk of adrenal insufficiency and should carry a steroid emergency card 43 Whether insufficient patients on ongoing low-dose prednisolone treatment could benefit from receiving supplemental glucocorticoid doses during intercurrent illness and stress has not been shown, but it is standard procedure in all other types of adrenal insufficiency.
Our findings make a case for routine evaluation of adrenal function in patients on ongoing low-dose glucocorticoid treatment, but there are some concerns in regard to defining correct timing and frequency of such routine evaluation and the increased cost and workload.
It might not be feasible everywhere. Future perspectives such as using baseline morning P-cortisol measurements as an initial diagnostic screening tool should be further explored 45 If the activity of the underlying disease for which the prednisolone is prescribed allows prednisolone tapering and potentially withdrawal the need for daily replacement therapy should be considered.
Hydrocortisone is preferred for replacement therapy over prednisolone as its shorter half-life enables a more physiological mimic of the normal circadian rhythm of cortisol secretion 4748 with low nightly levels improving chances for adrenal recovery.
Adrenal function evaluation and treating the adrenal insufficiency with physiological doses of hydrocortisone might enable reduction or even withdrawal of prednisolone, thereby reducing other prednisolone-induced side effects such as osteoporosis, diabetes and hypertension. In conclusion, we have investigated secondary adrenal insufficiency in the particular clinical situation where patients receive ongoing prednisolone treatment in a dose that in itself is too low to cover extra glucocorticoid needs during stress.
We found that more than one-third of the patients had adrenal insufficiency. As low-dose glucocorticoid treatment is widely used, not only in rheumatoid arthritis, but in many different conditions, the prevalence is alarming and many patients might have unidentified adrenal insufficiency.
If future studies were to find the same benefit from hydrocortisone replacement strategy in patients with glucocorticoid induced adrenal insufficiency as for other patients with adrenal insufficiency, clinical management guidelines would have to be implemented for this patient group.
The authors declare that there is no conflict of interest that could be perceived as prejudicing the impartiality of this clinical study. S W Borresen made primary contributions to data collection and analysis, interpretation of results, and writing of the manuscript.
❿Risk for Adrenal Crisis – Download PJ's Protocol - Parent Project Muscular Dystrophy
Background: Patients on long-term glucocorticoid treatment are at risk of adrenal insufficiency during glucocorticoid treatment. High-dose glucocorticoid treatment is often sufficient to overcome most stressful situations. Contrary to patients in replacement therapy for adrenal insufficiency, patients treated with long-term low-dose glucocorticoids for various reasons are often not instructed in self-administration of supplemental doses in stressful situations.
P-cortisol was measured before and 30 min after Synacthen injection. Since prednisolone treatment is often sustained for years in these patients, adrenal suppression is likely equally prolonged. Our findings raise the question whether a Synacthen test should be routinely performed in patients on long-term low-dose glucocorticoid treatment and insufficient patients handled with the same cortisol replacement strategies as other patients with verified adrenal insufficiency.

❾-50%}Adrenal crisis caused by prednisone
This explains the fact that although only one or two doses of glucocorticoid are sufficient to suppress the HPA axis, the recovery is usually rapid. On the other hand, with prolonged use of glucocorticoids, the recovery of the HPA axis is much delayed 1 , 2.
Glucocorticoids have been used for their anti-inflammatory and pharmacological effects in multiple different disease entities including rheumatologic disorders, asthma, oncological disorders and many others. There are different studies that looked into effect of exogenous chronic glucocorticoid use on the HPA axis, and timing of recovery. However, depending on the glucocorticoids formulation used, the duration of therapy, the use of a variety of weaning protocols and the different diagnostic tests used to assess adrenal function, it is rather difficult to draw general conclusions.
In this review, we will focus on a few most common medical conditions for which glucocorticoids are encountered in children. Glucocorticoids have been widely used in the treatment of childhood leukemia. These patients are at a high risk for infectious complications, which makes identification of secondary adrenal insufficiency in these children critical. There are multiple studies that looked into the effect of chronic glucocorticoid use on the HPA axis and timing of recovery in this population of patients.
Felner et al. All patients were noted to have testing consistent with adrenal insufficiency on day 1 after cessation of glucocorticoid therapy.
Time for recovery of the HPA axis ranged from 4—8 weeks. Mahachoklertwattana et al. Most patients showed recovery of the HPA axis by 4—12 weeks. Einaudi et al. One arm received 22 days of prednisone tapering over 9 days and the second group received 22 days of dexamethasone which was weaned over 9 days. All patients demonstrated recovery of HPA axis by 10 weeks. Based on the above studies, it appears that most patients demonstrated recovery of HPA axis between 4—10 weeks after cessation of therapy.
Glucocorticoids are widely used for treatment of hemangiomas in infants. Mendoza-Cruz et al. The infants received high dose of prednisolone for an average of 3—6 months, weaned over 4—6 weeks. Salivary cortisol was used to assess recovery of circadian rhythm, as this would be the first sign of recovery of HPA axis.
Circadian rhythm was noted to be established by 6 weeks after cessation of oral steroids. All infants recovered and none had persistent adrenal insufficiency by 10—12 weeks after cessation of glucocorticoid therapy.
Inhaled corticosteroids ICS have been widely used in the treatment of persistent asthma for a long time. It was believed that when used within recommended doses, the risk for clinically relevant adrenal suppression is minimal 7. However, with increasing case reports of adrenal insufficiency with the use of ICS, the importance of understanding the risk factors associated with HPA suppression have become more obvious.
Fluticasone propionate is much more likely to cause clinically symptomatic adrenal suppression compared to other ICS like beclomethasone, triamcinolone and budesonide. Eid et al. These patients had early morning cortisol levels assessed after using the medication for 3—13 months. Seventeen percent of patients on low dose ICS had morning cortisol levels of less than 5. Those children who were switched to different formulations or lower doses were noted to demonstrate improvement in cortisol levels after changing the medication.
Breborowicz et al. These children had their adrenal function evaluated by early morning cortisol and low dose ACTH stimulation test. None of the patients demonstrated any evidence of adrenal suppression The current guidelines for screening for adrenal insufficiency in the setting of ICS use recommend screening high risk patients including: chronic use of moderate to high dose of high potency ICS for longer than 6 months; concurrent use of inhaled or topical corticosteroids; frequent medication with oral glucocorticoids, and low body mass index BMI There are multiple provocative tests which may be used for evaluation of the HPA axis.
These provocative agents test different levels of the HPA axis. Insulin tolerance test ITT has long been considered the gold standard as it assesses the integrity of the full HPA axis. However, ITT has not been widely used in many institutions given the risk of hypoglycemia and the usual presence of multiple contraindications.
In addition, it can be resource intensive and expensive Metyrapone stimulation test is considered to be a sensitive test and comparable to ITT since it evaluates integrity of the HPA axis as a whole. It is based on the fact that metyrapone inhibits 11 hydroxylases, leading to decreased cortisol level, and thus stimulating the pituitary secretion of ACTH.
The use of this test has been challenging due to unavailability of metyrapone and risk of inducing an adrenal crisis. The variation in ACTH assays and availability of 11 deoxycortisol assays make this test a suboptimal modality for testing in these children 16 , However, there are some challenges in regards to techniques for dilution of the ACTH preparation due to lack of standardized protocols and cut off thresholds.
This has led to controversies about the accuracy value of the test. Since prednisolone treatment is often sustained for years in these patients, adrenal suppression is likely equally prolonged. Our findings raise the question whether a Synacthen test should be routinely performed in patients on long-term low-dose glucocorticoid treatment and insufficient patients handled with the same cortisol replacement strategies as other patients with verified adrenal insufficiency.

Secondary adrenal insufficiency can result from inadequate stimulation of the adrenal glands due to either insufficiency or inadequate secretion of adrenocorticotropic hormone ACTH.
This may occur due to a variety of reasons including hypothalamic defects, hypopituitarism, defects in synthesis and processing of ACTH and chronic glucocorticoid use.
The mortality and morbidity associated with secondary adrenal insufficiency depends on the underlying etiology. However, missing the diagnosis could lead to detrimental consequences. In addition to being used as a replacement therapy for adrenal insufficiency, glucocorticoids have been widely used for their anti-inflammatory and pharmacological effects in a variety of medical conditions. The hypothalamic-pituitary-adrenal HPA axis can be suppressed after a single dose of steroid, but typically recovers quickly.
With chronic glucocorticoid, recovery of HPA axis might take longer. Understanding the timeline for recovery of the HPA axis and tests used to assess adrenal function and the HPA axis is crucial to both avoiding missing a diagnosis of adrenal insufficiency and the use of unnecessary steroids for replacement therapy. Steroidogenesis is controlled by multiple factors including the HPA axis.
ACTH, secreted by the anterior pituitary gland, stimulates synthesis of cortisol and androgens in the adrenal cortex. ACTH is also thought to have an effect on stimulating growth and maturation of the adrenal gland.
In the absence of ACTH, the adrenal glands undergo atrophy 1. The HPA axis, like many endocrine systems, is a classic example of the feedback system Figure 1. Glucocorticoids, whether endogenous or exogenous, exert negative feedback inhibition at the pituitary and hypothalamus levels. The glucocorticoid effects may be divided into acute and delayed phases. The acute phase usually occurs within minutes after administration. The delayed phase, on the other hand, occurs after 2—20 h and extends up to days.
This phase is mainly related to the inhibition of gene transcription factors of the pro-opiomelanocortin POMCleading to decreased synthesis of ACTH. The delayed phase is dependent on the dose and duration of glucocorticoid use but typically occurs with chronic glucocorticoid use. This explains the fact that although only one or two doses of glucocorticoid are sufficient to suppress the HPA axis, the recovery is usually rapid.
On the other hand, with prolonged use of glucocorticoids, the recovery of the HPA axis is much delayed 12. Glucocorticoids have been used for their anti-inflammatory and pharmacological effects in multiple different disease entities including rheumatologic disorders, asthma, oncological disorders and many others. There are different studies that looked into effect of exogenous chronic glucocorticoid use on the HPA axis, and timing of recovery.

This has led to controversies about the accuracy value of the test. Suggestions have been made about increasing the cut off range for HDST to improve sensitivity of the test.
Giordano et al. The use of glucagon as a provocative agent for assessment of HPA axis has also been studied. Its use in conjunction with growth hormone GH assessment in GH provocative testing protocols makes it particularly useful. Bottner et al. Another cortisol cutoff was suggested at The widespread use of glucocorticoids for their potent anti-inflammatory and pharmacological effects comes at the risk of side effects such as secondary adrenal insufficiency.
Identifying patients at high risk for developing adrenal insufficiency and the appropriate testing protocols is crucial to avoid unnecessary glucocorticoid replacement on one hand, and missing a diagnosis of adrenal insufficiency with detrimental consequences on the other.
Use of exogenous glucocorticoids is known to cause suppression of the HPA axis. Secondary adrenal insufficiency may be noted with oral and inhaled glucocorticoid administration. Typically, the HPA axis recovers fairly quickly if glucocorticoids have been used for less than 10—14 days. If glucocorticoids have been used for 2 weeks or longer then weaning of steroids and assessment of the integrity of the HPA axis are recommended.
In the meantime, patients should be educated about the use of steroid coverage for stress until recovery of HPA axis is documented. The optimal time to test for HPA axis recovery following prolonged glucocorticoid use remains controversial due to variability of data for timelines of when that occurs.
In general, the earliest that HPA axis recovery may be seen is about 4 weeks post-cessation of prolonged glucocorticoid use. It would be therefore reasonable to plan assessment of HPA axis around that time and then every 1—2 months until recovery is documented. ITT is considered to be the gold standard but is not widely used due to risk of side effects.
Metyrapone stimulation test is believed to be comparable to ITT and is a good alternative test. However, the risk of adrenal crisis and limited availability of metyrapone itself make this test less appealing. Low dose ACTH stimulation test is a highly sensitive test for secondary adrenal insufficiency. It does not evaluate recovery of the axis at the hypothalamus and pituitary level.
Moreover, there are some technical concerns about the dilution techniques and lack of standardized protocols for this testing which further complicate the issue. Glucagon stimulation test is an alternative as well, but again there are different cortisol cutoff thresholds published which makes standardization difficult.
Figure 1 The figure demonstrates the hypothalamic-pituitary-adrenal axis. Both endogenous and exogenous glucocorticoids exert negative feedback effect on both pituitary and hypothalamus levels. This negative feedback effect of exogenous glucocorticoid administration may lead to secondary adrenal insufficiency.
Recovery of steroid induced adrenal insufficiency. Transl Pediatr ;6 4
Secondary adrenal insufficiency is most commonly caused by medications, such as prednisone, intra-articular injections with steroids. If stress doses of steroids are not given, the body can experience adrenal crisis, which can be life-threatening. Missing doses of daily steroids for more than. If stress doses of steroids are not given, the body can experience adrenal crisis, which can be life-threatening. Missing doses of daily steroids for more than. We here show that glucocorticoid-induced adrenal insufficiency is also a problem during ongoing low-dose prednisolone treatment. Our study differs from previous. AI caused by oral corticosteroids (OCS) is not well-recognized or commonly diagnosed but is often associated with reduced well-being and can be. Signs and symptoms of adrenal insufficiency often come on gradually and progressively worsen over months. Inhaled corticosteroids ICS have been widely used in the treatment of persistent asthma for a long time.Adrenal suppression, or adrenal crisis, is a potentially life-threatening complication of steroid use. It is important to know that you may be at risk of an adrenal crisis when:.
If you experience any signs of adrenal crisis, go to the Emergency Room and alert your neuromuscular team. Cortisol is a hormone that is produced by your adrenal glands, which sit on top of the kidneys. Cortisol impacts the function of many body systems. When the body is under any kind of stress serious injury, severe infection, etc. When you are taking steroids, your daily dose of steroids provides your body with cortisol, so your adrenal glands temporarily shut down and do not produce cortisol.
During normal daily stress, your daily dose of steroid is generally an adequate amount of cortisol for your body. However, when your body experiences additional stresses such as serious injury, severe infection, etc. If stress doses of steroids are not given, the body can experience adrenal crisis, which can be life-threatening.
Missing doses of daily steroids for more than 24 hours can also cause adrenal crisis. Although side effects to steroids can be serious, your child should not suddenly stop taking steroids if side effects first appear. There are many ways to manage the side effects of steroids, including changing the type of steroid taken, changing the dose, and changing the dosing schedule.
Make sure your NMS tries everything to manage the side effects, and to institute these changes before steroids are discontinued. At this time, steroids are the only medicines known to help to maintain strength and function for people living with Duchenne. If you do make the decision to stop taking steroids, it is important that you do so under the supervision of a medical provider preferably, the prescribing medical provider and follow the corticosteroid therapy withdrawal guidelines outlined in the PJ Nicholoff Steroid Protocol download.
Watch very carefully for signs of life-threatening adrenal crisis during the corticosteroid taper, and for one year post-taper during times of serious injury or illness. Missing doses of daily steroids for more than 24 hours can also cause life-threatening adrenal crisis.
If oral corticosteroids are missed on days when they are normally given for more than 24 hours, IV doses should be given. Be sure to share the PJ Nicholoff Steroid Protocol download with your doctor and create a plan together about what to do in case of a missed dose. Recommendations for supplemental stress doses are provided in the PJ Nicholoff Steroid Protocol download.
It is important that you share this critical information with your doctor during times of severe illness, surgery, or trauma to avoid life-threatening adrenal crisis. Keep the PJ Nicholoff Steroid Protocol download available to you, and your medical providers, in case of a medical emergency or admission.
