[Effect of the syndrome of asthma of effort on work fitness of bronchial asthma patients].
A total of 133 patients aged 35 to 55 years with bronchial asthma (BA) were examined. Of these 85 patients showed an infection-dependent and 48 a steroid-dependent clinico-pathogenetic disease pattern. Physical performance was studied with regard to the character of occupation, the degree of respiratory function impairment and the effects of intal and orciprenaline sulfate on the reproducibility of asthma of effort (AE) and performance of that category of patients. The development of AE was found to lead to a further decrease of work fitness of BA patients irrespective of the clinico-pathogenetic disease pattern, the degree of external respiratory function impairment and the character of occupation, resulting in the limitation of physical work possibilities of BA patients. The data are also presented concerning the effects produced by intal and orciprenaline sulfate on AE reproducibility and work fitness of this group of patients and on the relationship between tracheobronchial hyper-reactivity and physical stimulus in the development of AE. Intal action was more pronounced as compared to orciprenaline sulfate. The data thus obtained can promote the improvement of the activity of the medical expert commission for evaluation of working capacity as well as of the standards of work recommendations in BA patients.
