Objective To summarise the long term efficacy of antiobesity drugs in reducing weight and improving health status.Design Updated meta-analysis of randomised trials. Data sources Medline, Embase, the Cochrane controlled trials register, the Current Science meta-register of controlled trials, and reference lists of identified articles. All data sources were searched from December 2002 (end date of last search) to December 2006. Studies reviewed Double blind randomised placebo controlled trials of approved anti-obesity dugs used in adults (age over 18) for one year or longer.
Studies evaluating the long-term efficacy of anti-obesity agents are limited to orlistat and sibutramine. Both drugs appear modestly effective in promoting weight loss; however, interpretation is limited by high attrition rates. Longer and more methodologically rigorous studies of anti-obesity drugs that are powered to examine endpoints such as mortality and cardiovascular morbidity are required to fully evaluate any potential benefit of such agents.

Oral glucocorticoids are commonly used across every field of medicine; however, discontinuing them in patients can be challenging. The risk of acute adrenal crises secondary to glucocorticoid withdrawal can be fatal and arises from chronic suppression of the adrenal glands. Identifying risk factors for adrenal suppression in dermatological patients, such as doses greater than 5 to 7.5 mg of prednisone equivalent, duration of glucocorticoid use greater than 3 weeks, certain medications, and comorbidities, can help risk-stratify patients. The use of adrenal gland testing such as basal cortisol levels and adrenocorticotropic hormone stimulation tests can confirm adrenal suppression in patients. This review article provides an approach that dermatologists can use to minimise the risk of adrenal insufficiency in patients discontinuing glucocorticoids and when it may be appropriate to use adrenal gland testing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
