[Asthma in the elderly].

INTRODUCTION
Asthma in the elderly is a growing clinical problem. It affects 6 to 7% of this age-group, but making the distinction between asthma and chronic obstructive pulmonary disease is more difficult as patients get older.


STATE OF THE ART
This difficulty is due to a number of factors: the confounding role of smoking, and also the physiological effects of ageing on the airways which renders airway obstruction more resistant to bronchodilation. Elderly asthmatics can be divided on clinical grounds into two arbitrary groups: "ageing asthmatics" who have had asthma since childhood or adolescence and "late-onset asthmatics" who may present following an infective episode. Certain features of asthma in the elderly include: poor perception of breathlessness, technical difficulties in making reliable pulmonary function measurements and the extrapulmonary manifestations (impact on quality of life).


PERSPECTIVES
The therapeutic strategy is much the same as for younger asthmatics but certain aspects take on greater importance: concerns about osteoporosis with long-term corticosteroid therapy (both oral and inhaled), the risk of arrhythmias with beta-2 adrenergic drugs and the significant side-effects of theophylline justifies, in difficult cases, consideration of anticholinergic and/or anti-leukotriene therapy.


CONCLUSION
Most importantly, for elderly asthmatics it is a treatment regimen that is as simple as possible and is backed up by a written self-management plan that will improve outcomes.
