Effects of the biopsychosocial approach (BPSA) on exercise-induced asthma (EIA)

The Biopsychosocial Approach (BPSA) is a treatment program for allergic patients which includes therapy for psychological, behavioral and social factors as well as for physical problems, following basic principles of psychoneuroimmunology. BPSA was applied to patients with bronchial asthma and favorable results were obtained. The mechanism of the therapeutic effects of BPSA included normalization of the patient's autonomic nervous function, levels of blood histamine, and circadian rhythm of lymphocyte activity. BPSA was also used in patients with exercise induced asthma (EIA) and the same parameters were evaluated. Results showed that patients with EIA recovered physiological homeostasis after BPSA therapy normalized blood levels of histamine and substance P (SP), skin reactions to histamine and SP, and autonomic nervous function. We conclude that BPSA is effective for treating patients with EIA.
