View clinical trials related to Adrenal Suppression.
Filter by:Recently there has been concern about the effect of inhaled steroids, routinely used in the treatment of asthma, on the body's ability to produce its natural stress hormone cortisol. Failure of adequate cortisol production in times of stress e.g. illness, can result in serious illness or death. Patients receiving longterm steroid treatment may have reduced levels of cortisol and not be able to produce adequate amounts in times of need, a process called adrenal suppression. Initially it was thought that the absorption of inhaled steroids into the bloodstream would be too low to cause adrenal suppression however high profile deaths followed by a national survey revealed a number of fatal or near fatal cases of adrenal suppression. The vast majority of these were in children. Since then doctors have been encouraged to ensure that children on high doses of inhaled steroids carry a steroid alert card and that the ability of their adrenal glands to produce adequate amounts of cortisol is checked. However it is unknown what dose of inhaled steroids puts one at risk, whether age or gender affects one's risk and when to check the function of the adrenal gland. The Short Synacthen Test (SST) investigates the ability of the body's adrenal glands to produce cortisol. Presently the SST requires intravenous (i.v) cannulation through which Synacthen is injected to stimulate the adrenal glands and multiple blood samples are collected to assess the response in terms of cortisol production. It is invasive, time consuming and unpleasant for the child. Our project aims to produce a noninvasive alternative to the current SST, with Synacthen given nasally and using saliva to measure the subsequent production of cortisol. A noninvasive test will allow us to establish the first normal ranges for children and determine which children with asthma are at risk of adrenal suppression.

Gynecologic Oncology patients have several different chemotherapy regimens, and dexamethasone is now routinely given to prevent allergic reactions to the chemotherapeutic agents. The most common chemotherapeutic agents used are paclitaxel and carboplatin. This combination regimen is given every three weeks for a total of 5-6 doses. Each dose is given after administration of 20 mg dexamethasone twelve hours prior to and the morning of chemotherapy. Dexamethasone is used for its antiemetic effects, but also to minimize the potentially fatal hypersensitivity reaction that can occur with paclitaxel. Another commonly used chemotherapy regimens is weekly cisplatin given with one dose of dexamethasone for cervical cancer. Chronic steroids are known to cause adrenal suppression, but it is not known if the amount of dexamethasone given with the gynecologic cancer chemotherapy regimens described above causes adrenal insufficiency in these patients. The investigators hypothesis is that some women receiving steroids with their chemotherapy may have adrenal insufficiency, and that they will have greater than normal chemotherapy-related fatigue.
