Diagnosis of adrenal insufficiency in eosinophilic esophagitis: The importance of timing of cortisol measurements in interpreting low-dose adrenocorticotropic hormone stimulation testing

[Comparison of Different Doses of ACTH Used in ACTH Stimulation Test to Determine the Subtypes of Primary Aldosteronism]. To compare the diagnostic value of adrenocorticotropic hormone (ACTH) stimulation test (AST) with different doses of ACTH combined with midnight administration of 1 mg dexamethasone for the determination of the subtypes of primary hyperaldosteronism (PA

Plasma aldosterone response to ACTH stimulation test for diagnosis of primary aldosteronism: a cross-sectional study. The diagnosis of primary aldosteronism (PA) requires screening and confirmation testing. The present study examined whether the 1 µg ACTH stimulation test for plasma aldosterone concentration (PAC) can accurately diagnose PA by bypassing the regular confirmatory steps of PA diagnosis. A cross-sectional study with a total of 36 patients with an aldosterone-renin ratio (ARR) > 20 ng/dL per ng/m/hr were included. The confirmation test for PA was performed by saline infusion and the patients were categorized into PA and non-PA. PAC was collected at 20 and 40 min after 1 µg ACTH stimulation test. Multivariable logistic regression analysis was performed, and the associations

Low-Dose ACTH Stimulation Test in Obesity: A Randomized Dose Assessment. The short cosyntropin test is widely used for adrenal insufficiency screening and diagnosis. Lower cosyntropin doses may have greater sensitivity vs. the standard dose in detecting adrenal dysfunction. Obesity and overweight are increasing, impacting the clinical presentation of some diseases. Currently more than 50

Evaluating the low-dose ACTH stimulation test (LDST) in neonates: Ideal times for cortisol measurement. Low-dose adrenocorticotropic hormone stimulation testing (LDST) can be used to diagnose central adrenal insufficiency. However, uncertainty remains over optimal times to draw serum cortisol levels. To determine optimal times to draw serum cortisol levels for the LDST in neonates

Evaluating the low-dose ACTH stimulation test in children: Ideal times for cortisol measurement. Central adrenal insufficiency (AI) can be diagnosed with the low-dose ACTH stimulation test (LDST). Protocols determining timing of cortisol sampling vary, with 30 minutes after stimulation being most common. To determine optimal times to draw cortisol levels and factors predicting timing of peak

Validation of a low-dose adrenocorticotropic hormone stimulation test in healthy neonatal foals. To determine the lowest ACTH dose that would induce a significant increase in serum cortisol concentration and identify the time to peak cortisol concentration in healthy neonatal foals. Prospective randomized crossover study. 11 healthy neonatal foals. Saline (0.9% NaCl) solution or 1 of 4 doses

A Study to Evaluate Cortisol Reserve in Response to Adrenocorticotropic Hormone (ACTH) Stimulation Test Following Baxdrostat Treatment Compared to Placebo in Participants With Uncontrolled Hypertension The main purpose of this study is to assess the serum free cortisol response after ACTH stimulation test at baseline and at Week 8 in participants with uncontrolled hypertension. This is a placebo -controlled study to evaluate cortisol reserve after ACTH stimulation test following treatment with 2 milligrams (mg) baxdrostat versus placebo.The study consists of 3 period:4-week screening period.An 8-week double-blind treatment period.A safety follow-up 2 weeks after last dose.Participants will be randomized in a 2:1 ratio to one of 2 treatment arms:BaxdrostatPlaceboParticipants will receive either

Comparison of 2 Doses for ACTH Stimulation Testing in Dogs Suspected of or Treated for Hyperadrenocorticism Lowering the cosyntropin dose needed for ACTH stimulation would make the test more economical. To compare the cortisol response to 1 and 5 μg/kg cosyntropin IV in dogs being screened for hyperadrenocorticism (HAC) and in dogs receiving trilostane or mitotane for pituitary-dependent HAC . Healthy dogs (n = 10); client-owned dogs suspected of having HAC (n = 39) or being treated for pituitary-dependent HAC with mitotane (n = 12) or trilostane (n = 15). In this prospective study, healthy dogs had consecutive ACTH stimulation tests to ensure 2 tests could be performed in sequence. For the first test, cosyntropin (1 μg/kg IV) was administered; the second test was initiated 4 hours after

Multidrug-Resistant Tuberculosis and Its Association with Adrenal Insufficiency: Assessment with the Low-Dose ACTH Stimulation Test Background. Multidrug-resistant tuberculosis (MDR-TB) is a major public health care concern that affects the life of millions of people around the world. The association of tuberculosis and adrenal insufficiency is well known; however, it is thought to be less prevalent every time. A spike in TB incidence and a lack of evidence of this association in patients with MDR-TB call for reassessment of an illness (adrenal dysfunction) that if not diagnosed could seriously jeopardize patients' health. Objective. To determine the prevalence of adrenocortical insufficiency in patients with MDR-TB using the low-dose (1 μg) ACTH stimulation test at baseline and at 6-12

Diagnostic Value of ACTH Stimulation Test in Determining the Subtypes of Primary Aldosteronism. Adrenal venous sampling is recommended as the golden standard for subtyping primary aldosteronism (PA). However, it is invasive and inconvenient, and seeking a better way to make differential diagnosis of PA is necessary. The objective of the study was to evaluate the diagnostic value of ACTH ). An ACTH stimulation test under 1 mg DST was performed in all patients. Plasma aldosterone and cortisol levels were measured every 30 minutes until 120 minutes after the iv injection of 50 IU ACTH. During the ACTH stimulation test, aldosterone levels in APA and UAH were similar (P > .05) but higher than those in BAH (P < .001). Furthermore, stimulated aldosterone levels of unilateral PA (APA and UAH

Study of Adrenal Functions using ACTH stimulation test in Egyptian children with Sickle Cell Anemia: Correlation with Iron Overload Sickle-cell anemia is characterized by defective hemoglobin synthesis with production of sickle hemoglobin. Sickle red blood cells become deformed and rigid with difficulty to pass through narrow capillaries and frequent clotting and thrombosis leading to repetitive vascular occlusions and progressive organ damage. We conducted this work to study some adrenal functions using ACTH stimulation test in Egyptian children with sickle cell anemia in correlation with iron overload. This study was conducted on 60 children with sickle cell anemia who were attendants of Hematology unit, Pediatric department, Tanta university hospital in the period from April 2012 to May 2014

THE LOW-DOSE ACTH STIMULATION TEST: IS 30 MINUTES LONG ENOUGH? Controversy persists regarding the use of the low-dose adrenocorticotropic hormone (ACTH) stimulation test (LDST) for the diagnosis of adrenal insufficiency (AI) and optimal test result interpretation. However, many centers are now using the LDST to assess cortisol secretion adequacy, and some only use a 30-minute cortisol level
