ciclesonide and Adrenal-Insufficiency

The purpose of this review is to compare and contrast the newer inhaled corticosteroid (ICS) ciclesonide with older ICSs in terms of pharmacodynamic and pharmacokinetic properties and how these affect comparative efficacy. In addition, clinical dosing strategies for ICSs including as-needed use will be explored.. Ciclesonide has demonstrated similar efficacy to that of fluticasone propionate and mometasone furoate in equipotent doses with a potentially improved therapeutic index. Once-daily administration of ICSs is generally not as effective as twice-daily. Continuous administration of ICSs does not change the natural history of asthma in either children or adults. Long-term administration of medium dose ICSs does not increase the risk of cataracts or osteopenia in children and young adults. Studies of as-needed ICSs in mild persistent asthma in adults and children have demonstrated mixed results, with some showing equal efficacy to continuous therapy and others showing superiority of continuous therapy.. Ciclesonide provides a newer ICS with favorable pharmacokinetics that may improve the therapeutic index, but assessment of its systemic effects such as growth await further studies. Continuous administration of ICSs in low to medium dose over many years is well tolerated. The use of as-needed ICSs in patients with mild persistent asthma is promising as a potential step-down therapy but awaits further studies.

Asthma is a complex disease of the respiratory tract associated with chronic inflammation in which an intricate network of cells and cellular factors plays a major role. Asthma is one of the most common chronic diseases, with an estimated 300 million cases worldwide, imposing a considerable burden on society in morbidity, quality of life, and healthcare costs. Inhaled corticosteroids (ICSs) form the gold standard, first-line therapy in the effective management of persistent asthma and reduce morbidity and mortality from asthma. However, long-term use of high-dose ICS therapy has potential to cause systemic side effects-impaired growth in children, decreased bone mineral density, skin thinning and bruising, and cataracts. Hypothalamic-pituitary-adrenal-axis suppression, measured by serum or urine cortisol decrease, correlates with the occurrence of systemic side effects of high-dose ICSs. Therefore, cortisol may be a relevant surrogate marker to identify the potential for adverse effects from ICS therapy. Ciclesonide is a new generation ICS with demonstrable safety and efficacy in the treatment of asthma. The unique pharmacologic characteristics of ciclesonide, such as reduced local adverse effects, lack of cortisol suppression, and the option for once-daily dosing, may improve compliance with therapy and allow long-term use of ICSs without fear of systemic adverse effects.

This case series intends to highlight the association between decreased linear growth velocity and adrenal suppression in patients receiving inhaled corticosteroids for asthma. A potential treatment option is also discussed. Adrenal suppression secondary to inhaled corticosteroids has previously been reported and is often underrecognized. A decrease in linear height velocity has also been associated with inhaled corticosteroids. However, a decrease in height velocity has not been shown to predict adrenal suppression.. This case series of 15 patients receiving inhaled corticosteroids for control of asthma were noted to have a decrease in linear growth velocity ultimately associated with adrenal suppression. A change in inhaled corticosteroid to ciclesonide led to recovery of adrenal function without impacting asthma control.. Chart review from a pediatric pulmonology clinic was performed. Growth parameters and laboratory studies were recorded and analyzed. A mean decrease in height standard deviation score in the year prior to diagnosis of adrenal suppression was -0.59, -0.11, and -0.18, in pre-puberty, peri-puberty, and post-puberty patients, respectively. After ciclesonide therapy was initiated, a mean change in height standard deviation score of +0.40, +0.13, and -0.13, was noted for pre-puberty, peri-puberty, and post-puberty patients, respectively. A change in growth velocity of +5.3 cm/yr, +2.1 cm/yr, and -1.9 cm/yr, was noted for pre-puberty, peri-puberty, and post-puberty patients, respectively, after starting ciclesonide.. Height velocity should be monitored closely during routine asthma visits to identify potential adrenal suppression associated with inhaled corticosteroids use. Ciclesonide is a good option for asthma treatment that allows for adrenal recovery.
