Adrenal insufficiency

CONTEXT: Patients with adrenal insufficiency require increased hydrocortisone cover during major stress to avoid a life-threatening adrenal crisis. However, current treatment recommendations are not evidence-based. OBJECTIVE: To identify the most appropriate mode of hydrocortisone delivery in patients with adrenal insufficiency who are exposed to major stress. DESIGN AND PARTICIPANTS: Cross-sectional study: 122 unstressed healthy subjects and 288 subjects exposed to different stressors (major trauma [N = 83], sepsis [N = 100], and combat stress [N = 105])...

The past decade has seen several critical advances in our understanding of hypothalamic-pituitary-adrenal (HPA) axis regulation. Homeostatic physiological circuits need to integrate multiple internal and external stimuli and provide a dynamic output appropriate for the response parameters of their target tissues. The HPA axis is an example of such a homeostatic system. Recent studies have shown that circadian rhythmicity of the major output of this system-the adrenal glucocorticoid hormones corticosterone in rodent and predominately cortisol in man-comprises varying amplitude pulses that exist due to a subhypothalamic pulse generator...

PURPOSE OF REVIEW: Adrenal insufficiency is a rare disease characterized by cortisol deficiency. The evaluation of patients suspected of having adrenal insufficiency can be challenging because of the rarity of the disease and limitations in the biochemical assessment of the cortisol status by either basal or dynamic testing [adrenocorticotropic hormone (ACTH) stimulation test]. Prompt and adequate diagnosis is of paramount importance to avoid adverse outcomes. We aimed to summarize the recent developments in the conduction and interpretation of the ACTH stimulation test for the diagnosis of adrenal insufficiency...

Congenital adrenal hyperplasia is one of the most prevalent genetic endocrine diseases. A new guideline from the endocrine society offers expert opinion and evidence-based recommendations on the diagnosis and management of this challenging condition.

OBJECTIVE: This clinical practice guideline addresses the diagnosis and treatment of primary adrenal insufficiency. PARTICIPANTS: The Task Force included a chair, selected by The Clinical Guidelines Subcommittee of the Endocrine Society, eight additional clinicians experienced with the disease, a methodologist, and a medical writer. The co-sponsoring associations (European Society of Endocrinology and the American Association for Clinical Chemistry) had participating members...

CONTEXT: The diagnosis of adrenal insufficiency is clinically challenging and often requires ACTH stimulation tests. OBJECTIVE: To determine the diagnostic accuracy of the high- (250 mcg) and low- (1 mcg) dose ACTH stimulation tests in the diagnosis of adrenal insufficiency. METHODS: We searched six databases through February 2014. Pairs of independent reviewers selected studies and appraised the risk of bias. Diagnostic association measures were pooled across studies using a bivariate model...

OBJECTIVE: We aimed to estimate pooled percentages of patients with adrenal insufficiency after treatment with corticosteroids for various conditions in a meta-analysis. Secondly, we aimed to stratify the results by route of administration, disease, treatment dose, and duration. METHODS: We searched seven electronic databases (PubMed, MEDLINE, EMBASE, COCHRANE, CENTRAL, Web of Science, and CINAHL/Academic Search Premier) in February 2014 to identify potentially relevant studies...

Addison's disease may be complicated by hypertension and less commonly by heart failure. We review the pathophysiology of the renin-angiotensin-aldosterone axis in Addison's disease and how this is altered in the setting of hypertension and heart failure. An essential first step in management in both conditions is optimizing glucocorticoid replacement and considering dose reduction if excessive. Following this, if a patient with Addison's disease remains hypertensive, the fludrocortisone dose should be reviewed and reduced if there are clinical and/or biochemical signs of mineralocorticoid excess...

OBJECTIVE: Patients with Addison's disease (AD) on conventional replacement therapy have impaired health-related quality of life (HRQoL). It is possible that lower hydrocortisone (HC) doses recommended by current guidelines could restore HRQoL. We compared HRQoL in AD patients treated according to current HC recommendations to that of the age- and gender-standardized general population. SUBJECTS, DESIGN AND MEASUREMENT: We assessed HRQoL in a cross-sectional setting with the 15D instrument in a Finnish AD cohort (n = 107) and compared the results with those of a large sample of general population (n = 5671)...

CONTEXT: Conventional glucocorticoid replacement therapy fails to mimic the physiological cortisol rhythm, which may have implications for morbidity and mortality in patients with Addison's disease. OBJECTIVE: The objective of the study was to compare the effects of continuous sc hydrocortisone infusion (CSHI) with conventional oral hydrocortisone (OHC) replacement therapy. DESIGN, PATIENTS, AND INTERVENTIONS: This was a prospective crossover, randomized, multicenter clinical trial comparing 3 months of treatment with thrice-daily OHC vs CSHI...

PURPOSE OF REVIEW: The purpose of this article is to review the current therapy of Addison's disease and to highlight recent developments in this field. RECENT FINDINGS: Conventional steroid replacement for Addison's disease consists of twice or three-times daily oral hydrocortisone and once-daily fludrocortisone; however, new treatment modalities such as modified-released hydrocortisone and continuous subcutaneous hydrocortisone infusion have recently been developed...

Adrenal insufficiency is the clinical manifestation of deficient production or action of glucocorticoids, with or without deficiency also in mineralocorticoids and adrenal androgens. It is a life-threatening disorder that can result from primary adrenal failure or secondary adrenal disease due to impairment of the hypothalamic-pituitary axis. Prompt diagnosis and management are essential. The clinical manifestations of primary adrenal insufficiency result from deficiency of all adrenocortical hormones, but they can also include signs of other concurrent autoimmune conditions...
