Recovery of pituitary-adrenal axis after withdrawal or reduction of systemic corticosteroids in patients with bronchial asthma.

In 36 patients with bronchial asthma a new inhalable corticosteroid (Fluocortin-butyl-ester) was administered to reduce systemic steroids and especially to study the recovery of pituitary-adrenal function. On the basis of the present results, it can be said that patients with the least degree of emphysema and obstruction and with good coughing dynamics and productive expectoration are most suitable for therapy with inhalable corticosteroids. If the systemic steroid reduction is adequate, the recovery phase of the pituitary-adrenocortical system begins after about 5 months and the response to ACTH appraoches normal values after about 8-9 months. About 4 mg prednisolone-equivalent per day can be assumed to be the systemically effective limiting dose. The reducibility as a percentage of the initial dose-regardless of its absolute value- and the maintenance dose achieved also appear to be of equal importance for the recovery of the functional reserve of the pituitary-adrenocortical system. No relationship to the duration of the disease and the initial steroid dose could be demonstrated. The clinical picture of the corticosteroid withdrawal syndrome is dependent on endogenous cortisol synthesis. The symptoms disappear spontaneously with increasing synthesis.

The possible role of bradykinin as a mediator in bronchial asthma.

A variety of antiasthmatic drugs were examined in a bioassay of uterine cornua of rats for determining their influence upon Bradykinin induced contractions. 4 different actions were seen: pronounced, moderate and weak suppression of enhancement of Bradykinin-activity. The most pronounced blocking effect was seen with Fenoterol, Adrenaline and Pheniramine, a moderate effect with Prednisolone and Tolazoline, a weak effect with Propranolol and DSCG. Noradrenaline showed a stimulating effect. It is postulated that Bradykinin acts via alpha-stimulation with concomitant cAMP-decrease after specific binding to Bradykinin-receptors. The results of the study suggest that Bradykinin still must be discussed as a possible mediator in obstructive airway-disease.

Semi-depot hyposensitization in severe hay fever: its clinical effectiveness and the therapeutic problems. (A four year study using intranasal challenge testing to monitor success).

Hyposensitization treatment for at least two years using pyridine-extracted alum precipitated (PEAP) extracts was carried out on 332 cases of severe hay fever, some of which were steroid dependent. Subjective self-assessment and weekly average use of additional medication were recorded, nasal challenge tests were conducted before and during treatment and related to the clinical picture. Successful treatment was unrelated to age, though distinctly limited where there was a history of more 15 years illness. It was however related to the pollen count from 1973 to 1976 and to the type and number of the antigens to which there was a clinical response. In spite of specific hyposensitization 4,2% of the pollinosis cases developed additional pollen asthma. In the course of treatment there were several instances of an enlargement of the individual antigen spectrum; sensitization to pollen, mould fungi, house dust and animal epithelia were recorded. In a total of 11,850 injections there were severe local reactions in 16,2% rhinoconjunctivitis in 1,6% asthma in 0,4% and urticaria in 0,4%. One female patient went into anaphylactic shock 12 hours after the administration of the antigen extract. In about 20% of the injections granulomas developed, about the size of a cherry-stone, which persisted for up to six months and which in some instances were reactivated by severe exposure to allergens. There was an unusually high percentage of organ and generalised reactions whenever the treatment was continued using a new antigen solution without reducing the dose.
