Do corticosteroids weaken your immune system

Corticosteroids affect the nervous system indirectly in a number of ways, by maintaining normal plasma glucose levels, adequate circulation, and normal electrolyte levels. Direct effects of corticosteroids on the central nervous system occur, but are not well defined. Corticosteroid levels influence mood, behavior, electroencephalograph patterns, memory consolidation, and brain excitability. Chronic glucocorticoid treatment causes cell death in hippocampal neurons in rats, and elevated glucocorticoid in the hippocampus is thought to play a role in altered cognition, dementia, and depression in aging humans. 62 Patients with Addison disease are subject to apathy, depression, irritability, and psychosis, 63 symptoms that are alleviated by glucocorticoid, but not mineralocorticoid, therapy. Cushing disease patients sometimes develop neuroses and psychoses that are reversible with the removal of excess hormone. 64 Increases in brain excitability in hypercorticism and after mineralocorticoid treatment are a result of electrolyte imbalances. However, increased brain excitability induced by cortisol is not due to changes in sodium concentration. Chronic glucocorticoid treatment can also result in pseudotumor cerebri, primarily in children. 65

The low systemic exposure of des-ciclesonide following ciclesonide nasal aerosol administration was confirmed in a crossover trial in 29 healthy adults. The median C max of des-ciclesonide was 59 pg/mL following a single dose of ciclesonide nasal aerosol (296 mcg) compared to 602 pg/mL following a single dose of orally inhaled ciclesonide (320 mcg) and 12 pg/mL following a single dose of ciclesonide aqueous nasal spray (300 mcg). The pharmacokinetics of intranasally administered ciclesonide have been assessed in perennial allergic rhinitis patients resulting in similar exposure compared to healthy subjects.

In a study of asthmatic children 5-12 years of age, those treated with budesonide administered via a dry powder inhaler 200 mcg twice daily (n=311) had a -centimeter reduction in growth compared with those receiving placebo (n=418) at the end of one year; the difference between these two treatment groups did not increase further over three years of additional treatment. By the end of four years, children treated with the budesonide dry powder inhaler and children treated with placebo had similar growth velocities. Conclusions drawn from this study may be confounded by the unequal use of corticosteroids in the treatment groups and inclusion of data from patients attaining puberty during the course of the study. The growth of pediatric patients receiving inhaled corticosteroids, including PULMICORT RESPULES, should be monitored routinely (., via stadiometry). The potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the risks and benefits associated with alternative therapies. To minimize the systemic effects of inhaled corticosteroids, including PULMICORT RESPULES, each patient should be titrated to his/her lowest effective dose [see Dosage and Administration (2) , Warnings and Precautions () ] .

Patients requiring oral corticosteroids should be weaned slowly from systemic corticosteroid use after transferring to ALVESCO. Prednisone reduction can be accomplished by reducing the daily prednisone dose by mg on a weekly basis during ALVESCO therapy [see DOSAGE AND ADMINISTRATION ]. Lung function (FEV 1 or AM PEFR), beta-agonist use, and asthma symptoms should be carefully monitored during withdrawal of oral corticosteroids. In addition to monitoring asthma signs and symptoms, patients should be observed for signs and symptoms of adrenal insufficiency, such as fatigue, lassitude , weakness, nausea and vomiting, and hypotension .
