Background: Inflammatory alterations of respiratory airways have been found in patients with non-allergic asthma, but the triggering event has not been defined. An autoimmune activation of inflammatory cells has been hypothesized. Objective: To evaluate whether histamine-releasing factors are present in sera from non-allergic asthmatics. Methods: Twenty-four patients with non-allergic asthma underwent in vivo autologous serum skin test (ASST) and in vitro basophil histamine release assay using autologous basophils as well as basophils from normal donors. Twenty-seven subjects with respiratory allergy and three normal subjects were chosen as control. Results: ASST was positive in 14/24 non-allergic asthmatics (58%) whereas it was negative in all 30 control subjects (P
