    Notes: Twenty-nine patients with asthma and aspirin-sensitivity were studied in an attempt to induce tolerance to aspirin (ASA). Starting with the smallest ASA doses eliciting bronchial obstruction (threshold doses) we doubled the doses on subsequent days and finally achieved good tolerance of 600 mg ASA per day in 27 patients. It was more difficult to achieve tolerance in patients with low ASA-thresholds than in patients with high ones. Daily ASA administration led to prolongation of the refractory state but when the intervals between consecutive doses were increased aspirm hypersensitivity recurred. The pause sufficient for a recurrence of sensitivity to ASA was measured in 16 patients and ranged from 24 h to 9 days Twelve patients challenged with indomethauen after ASA-desensitisation showed good drug tolerance.

    Notes: Abstract To determine the role of mast cells in aspirin-induced bronchoconstriction, venous histaminemia was measured in 17 aspirin-sensitive patients before and after administration of aspirin. Ventilatory disturbances were measured spirographically. Venous histaminemia was determined according to Lorenz. In 11 patients the mean increase of histaminemia was from 39.6 ng/ml to 107.0 ng/ml. In the remaining 6 patients no change in histaminemia was observed after the challenge. In patients exhibiting the increase of histaminemia, symptoms of hypersensitivity to aspirin, other than dyspnea, were more common and stronger. The authors discuss a possible relationship of the aspirin effect, disturbances in prostaglandin synthesis and histamine release.
