Hématologie Adulte Prevalence of Adrenal Insufficiency Post-chemotherapy Adrenocorticotropia in...
Haematological MalignancyA recent meta-analysis involving 3753 patients treated with corticosteroids notes that the population with the highest prevalence of biological IS (68%) is onco-hematology. However, it is also the least studied population with no recent and significant prevalence study. A recent multicenter study including patients followed up oncology who received dexamethasone for antiemetic purposes at cumulative doses well below the doses used in Hematology, objective a prevalence of biological IS estimated at 16% at 3 months from the start of chemotherapy. The introduction of a substitution had led to an objective improvement in the quality of life estimated by EORTC QLQ-C30.
Optimising Steroid Replacement in Patients With Adrenal Insufficiency
Adrenal InsufficiencyAdrenal insufficiency is a condition where the adrenal glands do not produce an adequate amount of steroid hormones. The aetiology of adrenal insufficiency can be primary or secondary. Patients will adrenal insufficiency have increased morbidity and mortality. In recent years there has been concern regarding what is the optimal dose and regimen of steroid replacement for patients. Unfortunately there is no accurate way of monitoring if a patient is on too much or too little steroid. We have shown in hypopituitary patients with secondary adrenal insufficiency that higher doses of hydrocortisone may be harmful. This reason for this is not fully understood. In recent years, a modified release hydrocortisone tablet (Plenadren) taken once per day (unlike conventional immediate release hydrocortisone which requires twice or thrice daily regimen) has come on the market. This tablet has shown to a have a steroid profile that more closely resembles normal physiology, avoiding the peak steroid levels that occur during thrice daily regimens, which may be of importance for improving outcome in adrenal insufficiency patients. It also shown improved cardiovascular risk factors, glucose metabolism and quality of life in compared to conventional treatment. The aim of our study is to assess the effect of hydrocortisone therapy on how the body uses and breaks down (metabolises) steroids. This will be done by several different research methods: by measuring markers of steroid action and metabolism in blood, urine and within the fat tissue under the skin in the abdomen. These results will be compared in the same patient while on their usual hydrocortisone and after switching to modified release hydrocortisone for 12 weeks, and to results from a normal healthy control group who are not on steroid replacement. This will be the first study to assess the impact of this new modified release hydrocortisone in relation to tissue steroid metabolism. The results will potentially help us to improve the treatment of patients with steroid deficiency and reduce the side effects seen in these patients.
Modified-release Compared to Conventional Hydrocortisone on Diurnal Fatigue in Secondary Hypoadrenalism...
Adrenal InsufficiencyDespite optimized hydrocortisone replacement regimes, many patients with adrenal insufficiency (AI) suffer from impaired quality of life (QoL). Characteristically, patients report high fatigue levels at certain times during the day. A modified-release hydrocortisone has been shown to improve QoL, particularly fatigue, in patients with primary AI. However, it is unknown, if the same effect can be observed in patients with secondary AI. Further, no studies have evaluated the effect, taking into account the diurnal variation of fatigue. A novel survey method termed Ecological Momentary Assessments (EMA) has the potential to provide reliable measurements of diurnal variations in patient-reported outcomes, such as fatigue. We will compare the effect of modified-release compared to conventional hydrocortisone on fatigue in patients with secondary AI due to pituitary disease, and hereby assess the feasibility of EMA as outcome in future large-scale randomised clinical trials (RCTs).
Does Inhaled Busedonide or Fluticasone Impair Adrenal Function?
Adrenal InsufficiencyInhaled corticosteroids are largely used in patients with asthma or chronic obstructive lung diseases. The purpose of this study is to determine if the use of inhaled corticosteroids is associated with suppression of endogenous cortisol production, as seen in patients treated with pharmacologic doses of oral or parenteral steroids.
Prevalence of Hypoglycaemia in Congenital Adrenal Insufficiency
Adrenal InsufficiencyCongenitalChildren with congenital primary and secondary adrenal insufficiency, who are deficient in cortisol, are at risk for hypoglycaemia, irrespective of appropriate hydrocortisone treatment, which can lead to potentially serious neurological complications. Few series are described in pediatrics. The prevalence of hypoglycaemia is probably underestimated because it is often asymptomatic and capillary blood glucose monitoring is not always performed routinely. The objective of the study is to evaluate the prevalence of hypoglycaemia in children with adrenal insufficiency.
Effect of Treatment With Stress-Doses Glucocorticoid in Patients With Acute Respiratory Distress...
Acute Respiratory Distress SyndromeAdrenal InsufficiencyThe purpose of this study is to see if stress doses of hydrocortisone improve early outcome in patients who are in early stage of ARDS and with relative adrenal insufficiency.
Diagnosis of Central Adrenal Insufficiency in Patients With Prader-Willi Syndrome
Prader Willi SyndromeAdrenal InsufficiencyThe purpose of this study is to determine presence of central adrenal insufficiency in children with Prader Willi Syndrome using low dose (1 mcg) ACTH stimulation test compared to results of overnight metyrapone test.
Isolated ACTH Deficiency in Patients With Hashimoto Thyroiditis
Hashimoto DiseaseAdrenal InsufficiencyThe purpose of this study is to determine whether patients with Hashimoto thyroiditis and impaired well-being may have a partial secondary adrenocortical insufficiency.
Evaluation of the Muscular and Cutaneous Sodium Storage by 23Na MRI in Patients With Chronic Adrenal...
Adrenal InsufficiencyThis study investigates the sodium content in the calf muscle and the skin obtained via 23Na-magnetic resonance imaging in patients with chronic adrenal insufficiency compared to healthy controls.
Cortisol Response to Low Dose Cosyntropin Stimulation Test in the Late Afternoon
Adrenal InsufficiencyPrevious study showed that afternoon cosyntropin testing was associated with a sevenfold increased likelihood of failing the 1μg test. However, in that study, investigators used a 20.3 cm plastic tube, which might have led to uncompleted cosyntropin delivery. In ther current study investigators will study afternoon 1μg cosyntropin cortisol stimulation using a short 2.5 cm tube.
