Older people who use steroid inhalers for asthma or chronic obstructive pulmonary disease (COPD) are more likely to suffer particular bacterial infections, according to a large study published in the European Respiratory Journal . Worldwide, asthma and COPD affect hundreds of thousands of people and they are commonly treated with steroid inhalers to reduce symptoms and improve lung function.

A neb treatment has 2500 mcg of Albuterol, while two puffs of an MDI is 200 mcg of the same medicine. The increase in heart rate often noted with the neb reflects the higher dose. So how do we explain the often reported similar subjective and lung response in patients regardless of delivery method ? I’m not sure, but I wonder if the neb dose could be lowered without sacrificing response for those instances where the MDI is effective. Or approach nebs like we do with an MDI: start with 500 – 1000 mcg, and if desired take a second treatment.

Sacks et al. (2005) reported the case of a 72-year-old man, described as professionally successful, intelligent, and cultivated, with polymyalgia rheumatica, who after being treated with prednisone developed a psychosis and dementia , which several behavioral neurology and neuropsychiatry consultants initially diagnosed as early dementia or Alzheimer's disease . [12] Large dosage variations in the patient's medication (including a self-increased dosage from 10 mg/day to as much as 100 mg/day for at least 3 months) produced extreme behavioral changes, from missed appointments to physical altercations, and eventually admission to a psychiatric ward and later to a locked Alzheimer facility. During this time, neuropsychological testing showed a decline in the patient's previously superior IQ as well as deficits in memory, language, fluency, and visuospatial function, which given the patient's age was considered to be compatible with early dementia. When the steroid treatment ended after a year, the patent's confusion and disorganized appearance stopped immediately. Within several weeks, testing showed strong improvement in almost all cognitive functions. His doctors were surprised at the improvement, since the results were inconsistent with a diagnosis of dementia or Alzheimer's. Testing after 14 months showed a large jump in Full Scale IQ from 87 to 124, but mild dysfunction in executive function, memory, attentional control, and verbal/nonverbal memory remained. [12]
