    Notizen: Busereline acetate is an LH-RH agonist that was found to induce local reactions at the injection site or generalized minor skin reactions in some patients. Since these reactions may represent the first reaction of systemic anaphylaxis, we tested the non-specific histamine releasing activity of this drug by intradermal skin tests. It was found that all subjects tested had a positive wheal and flare reaction, the flare being significantly decreased by terfenadine. Benzyl alcohol, the preservative used in commercial preparation of busereline acetate, did not elicit a positive wheal and flare reaction in two patients who had experienced a clinically noticeable reaction. It is concluded that busereline is likely to be a non-specific histamine releasing compound.

    Notizen: The heterogeneity of pollen-allergic persons is well known but poorly characterized. Cypress is one of the major pollen-producing plants of the Mediterranean area. A study was undertaken to characterize the symptoms presented by patients allergic to cypress pollen and the heterogeneity of the IgE immune response between patients allergic only to cypress pollen and those who are polysensitized. Eighty-nine patients allergic to cypress pollen were studied, 26 being allergic only to cypress pollen. The IgE response was assessed by skin prick tests and the titration of serum total IgE and cypress-specific IgE by RAST. Clinical reactivity was assessed by symptom scores during the cypress pollen season and skin tests. Pollen counts were obtained. The clinical reactivity was similar in both patient groups. Rhinitis was present in all patients, conjunctivitis in 73.7–88.5%, and asthma in only 7.4–19.2%. The age of onset of symptoms caused by cypress pollen allergy was significantly greater in patients allergic to cypress pollen only. Total serum IgE was within the normal range in the cypress pollen group and significantly lower than in the polysensitized groups. Cypress pollen RAST was higher in the polysensitized group. We concluded that conjunctivitis is particularly common in cypress pollen allergy. Patients allergic only to cypress pollen may be unique in their way of expressing serum total IgE levels.

    Notizen: Specific immunotherapy (SIT) using a standardized mite extract is effective and safe when administered under optimal conditions. However, the duration of its effectiveness after cessation of treatment remains unknown. Forty asthmatic subjects who had received SIT with a standardized Dermatophagoides pteronyssinus (Der p) extract under the same protocol were studied. All had received SIT for a period of 12–96 months and were not receiving pharmacologic treatment. The FEV1 was within normal range in all patients. After cessation of treatment, patients were followed for up to 3 years at 6-month intervals. The patient was considered to have relapsed when symptoms of asthma and/or rhinitis occurred and/or when pulmonary function tests were impaired. Skin tests with increasing concentrations of Der p were carried out before and at the end of SIT. Forty-five percent of the patients did not relapse. The duration of efficacy of SIT was related to the duration of SIT itself (P 〈 0.04). Most patients who did not relapse had a decrease in skin test reactivity at the end of SIT, whereas most patients who relapsed did not show any change (P 〈 0.003). The duration of efficacy of SIT after its cessation depends upon the duration of SIT and may be predicted by the effect of SIT on skin tests.
