An 84-year-old male presented with a dermatophyte infection that had spread over nearly the entire body surface. The first signs had developed 48 years before. After treatment with galenic and corticosteroid preparations for diagnoses of "eczema" and "psoriasis", the lesions gradually extended over the body and to the nails. The cutaneous symptoms had worsened in recent year after the patient had started systemic cortisone treatment for bronchial asthma. He also developed diabetes mellitus, papulonodular lesions on the face and limbs, thinning of his hair and eyebrows and hyperkeratosis of the soles and palms.

Inhaled corticosteroids are considered by many to be the anti-inflammatory therapy of choice in adult asthma, given their remarkable efficacy and apparent safety. They are presently being prescribed to more patients, at larger doses, and for longer periods of time than ever before. Oropharyngeal candidiasis and dysphonia are the most commonly recognized adverse effects of therapy, but these topical phenomena cause no significant morbidity and are easily managed. By contrast, there is now increasing concern about the potential systemic effects of inhaled corticosteroids. These putative effects may include adrenal suppression, bone loss, skin thinning, increased cataract formation, decreased linear growth in children, metabolic changes, and behavioral abnormalities. Changes in adrenal function have been noted in patients using medications such as beclomethasone dipropionate and budesonide in doses exceeding 1,500 micrograms/day. The clinical relevance of these changes has yet to be clarified. Several short-term and cross-sectional studies have also revealed changes in biochemical markers of bone turnover and retrospective studies have found reduced bone density in asthmatics treated regularly with inhaled steroids. Long-term prospective studies assessing bone density changes remain to be done. Although much controversy exists, there is no unequivocal evidence that conventional doses of inhaled steroids significantly retard bone growth in children. Reports on skin changes, increased cataract formation, and behavioral changes are difficult to interpret because of several confounding factors. Although inhaled steroids should, at the present time, continue to be a recommended therapeutic option to all patients with symptomatic asthma, they should always be used in the lowest dosage compatible with disease control.

The role and adverse effects of methotrexate in the treatment of chronic corticosteroid-dependent asthma are discussed. Methotrexate is a folic acid antagonist that has been used as an anti-inflammatory agent in the treatment of arthritis. It also appears to be effective in reducing the corticosteroid requirements in patients with chronic corticosteroid-dependent asthma, a use that was first reported in 1986. Studies of this use of methotrexate in adults support a trial of methotrexate in patients with severe asthma who have been unable to discontinue corticosteroid use despite aggressive management of their asthma and who are experiencing severe corticosteroid toxicity. Experience with methotrexate in children with asthma is limited to case series. Adverse effects associated with the use of methotrexate for treatment of corticosteroid-dependent asthma include nausea, elevated serum aminotransferase, diarrhea, and thinning of hair. While methotrexate appears to reduce corticosteroid requirements in patients with chronic corticosteroid-dependent asthma, its role in asthma therapy still needs to be clarified.

Inhaled corticosteroids are being given to more patients, at increasing doses and for longer periods of time. This has led to renewed concern about side-effects, particularly when higher doses (> 1 mg day-1) are used. The side-effects of particular concern are adrenocortical suppression, bone resorption, decreased growth in children, skin thinning and cataract formation. Changes in adrenocortical function are seen in a small proportion of patients given doses of 1-2 mg day-1. Long-term studies of the effect of inhaled corticosteroids on bone density are not available. Cross-sectional studies of bone density have been performed, but confounding variables, such as previous courses of oral corticosteroids and poor matching of control groups, make the studies difficult to interpret. Short-term effects on markers of bone turnover have been demonstrated, but their relevance to the long-term risk of osteoporosis is unclear. Studies reporting an increased incidence of skin changes and cataract formation are difficult to interpret because of confounding variables and inadequate control groups. Further studies of the long-term side-effects of inhaled corticosteroids are now required to enable prescribers to judge better the relative benefits and risks of this important asthma therapy.

Asthma guidelines recommend the use of inhaled glucocorticoids (GCS). However, high doses increase the risk of systemic effects including suppression of the hypothalamic-pituitary-adrenal (HPA) axis by negative feedback, reduction of bone mass, inhibition of growth in children and skin thinning. Plasma concentration depends on the dose delivered from the inhaler, the distribution of delivery (ratio of lung to gut), and the degree of first-pass metabolism. Improving lung delivery increases lung absorption and reduces gut absorption and, depending on the extent of first-pass metabolism, may have significant effects on the systemic drug load. Qvar (3M Pharmaceuticals' hydrofluoroalkane beclomethasone dipropionate (HFA-BDP)), which produces an extra fine aerosol, improves lung delivery without producing clinically significant HPA suppression within the recommended dose range. Within this range Qvar produces no more HPA suppression than an equal dose of CFC-BDP and, in addition, lower doses of Qvar are effective in asthma control.

Inhaled corticosteroids are considered by many to be the therapy of choice in the treatment of asthma and allergic rhinitis. Systemic adverse effects are well known and are mainly dose dependent. Adverse cutaneous effects have also been characterized. Some of them are frequent and dose dependent, for example thinning of the skin and easy bruising. These adverse effects are probably present in about half of the patients treated with inhaled corticosteroids. The risk of these adverse effects is more important among elderly people and increases with the duration of the treatment and the daily dosage. Thinning of the skin and easy bruising are probably dependent on collagen synthesis modifications. Among rare or underestimated reactions, several adverse effects have been described such as angina bullosa hemorrhagica, acne and allergy. In this latter case, the attention should be paid to relevant clinical signs such as eczematous lesions of the face and aggravation of the nasal symptoms. Mucocutaneous infections related to inhaled corticosteroid use have also been reported, the most frequent being candidiasis. However, the frequency of symptomatic clinical infection is very rare. The risk of viral infection, especially with a herpes virus, has never been described. As cutaneous complications of corticosteroids are mainly dose dependent, these adverse effects could be prevented by attention to the daily dosage. Infection could be prevented by rising the mouth after inhalation and the use of a spacer device. If cutaneous adverse effects occur despite proper use of the inhaled corticosteroids and became unpleasant for the patient, discussion with a pneumologist or otorhinolaryngologist may be required but temporary halting therapy is rarely useful.

The incidence of drug-induced adverse effects is likely to increase as a result of advanced age and exposure of elderly patients to polypharmacy. Therefore, pharmacological therapy of asthma and chronic obstructive pulmonary disease (COPD) in the elderly patient can be potentially hazardous. beta(2)-agonists, administered as therapy for asthma and COPD, have recognised systemic sequelae, such as hypokalaemia and chronotropic effects, which may be life-threatening in susceptible patients. Adverse effects such as hypokalaemia can be aggravated by concomitant treatment with other drugs promoting potassium loss including diuretics, corticosteroids and theophyllines. In addition, relatively minor adverse events associated with the administration of beta(2)-agonists, such as tremor and blood pressure changes, may be of significance to the elderly patient leading to impairment in the quality of life. However, long-term treatment with beta(2)-agonists may reduce the incidence of drug-induced adverse effects as a result of beta-receptor subsensitivity. Oral and inhaled corticosteroids have been used for the treatment of acute asthma and COPD in the elderly patient. Long-term treatment with oral corticosteroids can result in serious systemic adverse effects such as suppressed adrenal function, bone loss, skin thinning and cataract formation. In contrast to beta(2)-agonists, oral corticosteroids can upregulate beta(2)-adrenoceptors and thereby potentiate the systemic sequelae of beta(2)-agonists. Hence, oral corticosteroids should be administered with caution for as short a duration as possible. Inhaled corticosteroids appear to be relatively well tolerated when administered at doses below approximately 1000 microg. However, larger doses of inhaled corticosteroids may affect hypothalamic-pituitary-adrenal function and bone turnover. In the case of inhaled corticosteroids, spacer devices, often used in older patients who cannot operate metered dose inhalers, can potentiate the systemic sequelae of both corticosteroids and beta(2)-agonists. The use of theophyllines in the treatment of COPD or chronic asthma is controversial. Theophyllines have a wide adverse effect profile and are prone to drug-drug interactions. The adverse effects may be mild or life threatening and include nausea and vomiting or sinus and supraventricular tachycardias. Therefore, theophyllines should be prescribed with extreme caution to elderly patients with asthma or COPD. In contrast, inhaled anticholinergic drugs such as ipratropium bromide and oxitropium bromide are generally safe in elderly patients and have useful bronchodilator function. Commonly reported adverse effects are an unpleasant taste and dryness of the mouth. When used as first-line therapy, anticholinergic drugs may optimise the bronchodilator effects of low-dose inhaled beta(2)-agonists in patients with chronic airflow obstruction, and hence obviate the need for higher doses.

Inhaled corticosteroids are considered to be the therapy of choice in the treatment of asthma and allergic rhinitis. However, various cutaneous adverse reactions have been described and are probably present in approximately half of patients. Some of these reactions are related to the daily dosage of steroids or the duration of treatment, for example: thinning of the skin, easy bruising, acne or peri-oral dermatitis, mucocutaneous infection and, especially, candidiasis. Other cutaneous side effects are independent of the dose, such as allergic reactions and a few other rare side effects. Adverse effects could be prevented by monitoring the daily dosage and the family history of the patients, and by following advice provided on the use of inhaled corticosteroids. Specific treatments for infection, acne or allergy can cure these side effects. However, cutaneous side effects can become unpleasant for the patient and temporarily withdrawing therapy has proven to be extremely effective.

Inhaled corticosteroids continue to be hallmark players in asthma control. In time, they induced fear, hope, and created numerous discussions in specialty literature. Usually, the studies focus more on their beneficial effects and less on adverse effects. Surprisingly, lately more was written about systemic effects. A detailed review of some recent studies demonstrates that the most feared systemic effects (risk for osteoporosis due to calcium and phosphate metabolic changes, adrenal suppression, skin thinning, cataract, growth problems in children and teenagers, glaucoma) are very rare. The local effects, if properly addressed by the physician and patient, can be largely diminished. The conclusion of this article is that there is a non-due fear for this class of medication with certain virtues in asthma and COPD therapy.

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.
