Objective: While the low dose short Synacthen® test (LDSST) is considered to be the gold standard to evaluate adrenal function, it is labor-intensive, invasive and inconvenient. The aim of the study is to identify cut-offs for spot serum cortisol for in-patients and morning serum cortisol for out-patients. The study also aims to describe the disease spectrum leading to suspicion of adrenal insufficiency in a Chinese out-patient cohort. Methodology: Adult patients were recruited from a tertiary hospital in Hong Kong. 423 in-patients were included consecutively from July 2013 to December 2013, and 422 out-patients from June 2014 to October 2014. Serum cortisol responses at 0, 20 and 30 minutes were evaluated. Results: For in-patients admitted for acute illness, a spot serum cortisol of ≤92 nmol/L indicated adrenal insufficiency, and a value of ≥494 nmol/L signaled adequate adrenal reserve. The respective morning cortisol values for out-patients who were ambulatory and not under stress were ≤124 nmol/L and ≥428 nmol/L. The percentage of unnecessary LDSST was higher in the in-patient cohort than the out-patient cohort (43% and 37%, respectively). The most common referral for out-patient LDSST was for suspected iatrogenic Cushing’s syndrome (ie: iatrogenic adrenal suppression) from Rheumatology. Conclusions The LDSST is of little added value in in-patients with spot serum cortisol of ≤92 nmol/L or ≥494 nmol/L and out-patients with morning serum cortisol of ≤124 nmol/L or ≥428 nmol/L. Spot and morning cortisol levels, for in and out-patients respectively, should be incorporated into endocrine protocols preceding the LDSST in the workup of adrenal insufficiency

Addisons disease is relatively rare than secondary adrenal insufficiency and result from progressive adrenocortical destruction. The common causes are idiopathic autoimmune atrophy and tuberculosis of adrenal glands. It is generally regarded as incurable in the sense that substitution therapy is required for the rest of the patients life. We report a case of tuberculous primary adrenal insufficiency which was confirmed by biopsy. This case was treated with antituberculous medication and showen to have improved adrenocortical function after six months.

Objectives: Among critically ill patients, there is usually impairment of the hypothalamic-pituitary- adrenal axis, leading to a condition known as critical illness-related corticosteroid insufficiency (CIRCI). The aims of this investigation are to determine the incidence of and characterize CIRCI among patients with COVID-19 as well as to analyze the outcomes of these critically ill patients. Methodology: This is a single-center, retrospective, cohort study that investigated the occurrence of CIRCI among critically ill patients infected with COVID-19. Results: In this cohort, there were 145 COVID-19 positive patients with refractory shock included, which reflects that 22.94% of the COVID-19 admissions have probable CIRCI. Patients who were given corticosteroids were found to have statistically significant longer median days on ventilator (p= 0.001). However, those on the corticosteroid arm were at higher risk of morbidity and mortality and a greater proportion of patients with organ dysfunction. Multivariable logistic regression analysis revealed that SOFA score was a significant predictor of mortality in CIRCI (p=0.013). Conclusion CIRCI has a unique presentation among COVID-19 patients because of the presence of a high level of inflammation in this life-threatening infection. It possibly is a harbinger of markedly increased risk of mortality in these patients.

BACKGROUND: Rapid adrenocorticotropin (ACTH) stimulation test using 250ug of ACTH (1-24) has been used as a standard test in the initial assessment of adrenal function. However, it has recently been suggested that a rnaximal cortisol response can be achieved with a much lower ACTH dose, and reducing the dose might further enhance the sensitivity of the test in the detection of mild adrenal insufficiency. This study was performed to evaluate the role of low-dose (lug) ACTH stimulation test in the assessment of adrenal function and the diagnosis of subtle adrenal insufficiency. METHODS: Twenty-two subjects with suspected adrenal insufficiency due to long-term corticosteroid use were included in this study. The correlations between clinical features and the serum cortisol responses to low dose (lug) and high dose (250 ug) ACTH stimulation were evaluated. RESULTS: In high dose test, 10 (67%) out of 15 subjects with clinical features of adrenal insufficiency showed decreased serum cortisol response (peak cortisol level <18 ug/dL), but 5 (33%) subjects showed normal response (peak cortisol level > 18ug/dL). On the other hand, 14 (93%) subjects with clinical features of adrenal insufficiency showed decreased serum cortisol response in low dose test, while only one showed normal response. In 7 subjects without clinical features of adrenal insufficiency, 5 subject (71%) showed normal response, and 2 subjects (29%) showed decreased response in both low and high dose tests. CONCLUSION: These results suggest that the 1-ug low dose ACTH stimulation test might be more sensitive than conventional 250-ug test in the detection of mild adrenal insufficiency. Further studies are needed to determine the optimal dose of ACTH and the criteria for normal response to ACTH stimulation.
