To investigate platelet functions in patients suffering from allergic diseases including asthma, blood was collected from ten asthmatic patients (five females, five males) and ten healthy controls (five females, five males) and by using whole-blood electrical impedance system; platelet count and platelet aggregation studies (maximum aggregation extent, maximum aggregation rate) were performed. Allergy screening was performed with skin test reactions and with high total and specific immunoglobulin E levels (CAP-Phadiatop system). Platelet count (333.1 ± 41.1 x 109/L), collagen induced the response of platelet aggregation (12.95 ± 4.19) and maximum rate of aggregation (8.00 ± 5.22) in allergic patients were found significantly higher than those of controls (252.1 ± 49.1 x 109/L; 8.33 ± 1.19; 4.28 ± 1.31) (p< 0.05). Also ADP induced response of platelet aggregation (18.21 ± 3.56) and maximum rate of aggregation (10.64 ± 2.12) in asthmatic patients were higher than controls (12.37 ± 2.63; 7.80 ± 1.64) with statistical significance (p< 0.01). Secretion products of activated platelets such as histamine, serotonin, PGF2α and PAF may play role in bronchial responsiveness in allergic asthma. The results of this study showed that platelet function tests were effected in asthmatic patients. The changes in platelet functions are thought to be related with increased IgE levels and stimulation of platelets by these antibodies.
