Corticosteroids constitute an ideal treatment for various inflammatory and autoimmune disorders due to their anti-inflammatory and immunomodulatory actions. However, corticosteroids have a considerable number of side effects, including hypertension, diabetes, lipid disorders, sleep apnea, osteoporosis, myopathy, and disorders of coagulation and fibrinolysis, which are components of Cushing's syndrome (CS). Corticosteroid-induced side effects are dependent on the formulation, route, dose, and time of exposure. However, the underlying pathogenetic mechanisms have not been clearly defined. A large body of evidence supports the role of an imbalance between vasoconstriction and vasodilation with possible links to nitric oxide, prostanoids, angiotensin II, arginine vasopressin, endothelins, catecholamines, neuropeptide Y, and atrial natriuretic peptide. Increased oxidative stress, renin-angiotensin system activation, increased pressor response, metabolic syndrome, and sleep apnea appear to be pathogenetically involved as well. The ideal treatment is the withdrawal of corticosteroids, which is most often impossible due to the exacerbation of the underlying disease. Alternatively, a careful plan, including the proper selection of the formulation, time, and route, should be made, and each side effect should be treated properly. The focus of the research should be to develop synthetic corticosteroids with anti-inflammatory effects but fewer metabolic effects, which so far has been unsuccessful.

Morbid obesity is a chronic disease affecting millions of Americans. The disorder is likely to increase in prevalence because currently one third of the American population is obese. Many factors are associated with morbid obesity, including psychological (eg, depression), physiological (eg, hypothyroidism) mechanisms, sleep disorders (eg, sleep apnea), drug therapy (antidepressants, antidiabetic agents, steroids), and genetics. Increasing numbers of morbidly obese patients are requiring critical care, presenting major challenges to professional staff across the disciplines. This manuscript presents a case study describing the experiences of a morbidly obese woman in the final years of her life from the perspective of her health professional relative. The patient typifies many of the major risk factors for morbid obesity; her story reveals many of the issues faced as she revolved in and out of the critical care and acute care system. Her substantive health problems affected multiple body systems and included hypothyroidism, congestive heart failure, hyperlipidemia, and subclinical Cushing's Syndrome, likely related to previous medical therapy (cortisone) for rheumatic fever in childhood. The case description addresses many integumentary system issues the patient experienced; skin injuries and infections that can pose serious life-threatening situations for the morbidly obese patient must be prevented or treated efficiently. Health professionals can learn a great deal and improve the care they provide by listening to morbidly obese patients.

The daily rhythm of the hypothalamo-pituitary-adrenal (HPA) axis is regulated by the central clock in the suprachiasmatic nucleus. Cortisol, a glucocorticoid, acts as a secondary messenger between the central clock and the peripheral tissues. Changes in clock time, as seen in shift workers, alters the HPA axis and results in metabolic disturbances associated with ill health. Depression, anorexia nervosa and obstructive sleep apnoea, are associated with cortisol rhythm phase shifts and increased cortisol exposure. Higher nocturnal cortisol exposure is observed in patients with Cushing's syndrome and adrenal incidentalomas with autonomous cortisol secretion and is associated with insulin resistance, and increased cardiovascular risk and mortality. A decrease in cortisol rhythm amplitude is seen in adrenal insufficiency, and despite replacement, patients have an impaired quality of life and increased mortality. Research on cortisol replacement has focused on replacing the cortisol daily rhythm by subcutaneous hydrocortisone infusions and oral modified release hydrocortisone formulations with the aim of improving disease control and quality of life.
