Apple allergy: the IgE-binding potency of apple strains is related to the occurrence of the 18-kDa allergen.

Low-temperature, acetone powder extracts were prepared from mature fruit of 16 apple strains. SDS-PAGE and immunoblot analysis revealed great variation in the relative amounts of the 18-kDa apple allergen in these extracts. EAST (RAST) scores, measured with individual and pool sera from patients allergic to birch pollen and apples, ranged from 0.2 to 4.0 and were related to the relative amount of the 18-kDa protein. These findings were confirmed by ELISA-inhibition assays, dose-related histamine release, semiquantitative evaluation of immunoblots by absorption/reflection densitometry, and skin prick tests with extracts of Golden Delicious, Boskoop, and Jamba apples (corresponding to a high, low, and very low 18-kDa allergen content). Additional open oral challenge tests were performed with two apple-allergic patients and 15 and 16 apple strains. With all methods, the deduced allergenic potency decreased in the following order: Golden Delicious > Boskoop > Jamba. Therefore, we concluded that the IgE-binding potency of apple strains depends on the occurrence of the 18-kDa allergen.

[Symptomatic therapy of pruritus (author's transl)].

The symptomatic therapy of generalized primary pruritus is reviewed. The topical therapy consists of skin care measures; more or less greasy ointments or creams should be used depending on the degree of dryness of the skin. It is to be noted that tenside-containing bath additives may promote drying of the skin, in pruritus patients they should be replaced with oil-based bath additives. Antihistamines have proved valuable in systemic therapy. The pharmacological effects of these H2 receptor antagonists is dealt with. The principles for selection of individual preparations from the vast number of substances available are commented on; combination therapy is gone into and also possible side-effects, particularly of ethylenediamine and piperazine antihistaminics. Glucocorticoids and antiphlogistics have no place in the treatment of generalized primary pruritus.

[Pharmacokinetics and metabolism of 3H-synephrine (author's transl)].

The physiological disposition of 1-(4-hydroxyphenyl)-2-methylamino-ethanol-tartrate (synephrine, Sympatol) in man had not been investigated to date. Therefore, we studied pharmacokinetics and metabolism of tritiated synephrine in man. Following short i.v. infusion in six patients about 80% of the administered radioactivity was recovered in urine. Two-thirds of the urinary tritium activity consisted of the deaminated p-hydroxymandelic acid. 10% were excreted as unchanged synephrine only. Following oral ingestion in ten patients the total urinary radioactivity was quite comparable to the i.v. experiments. Therefore, complete enteric absorption has to be stated. The amount of unchanged synephrine amounted, however, only to 2.5% of the dose. The resulting bioavailability has to be calculated to 22% only. The pharmacokinetic parameters are quite comparable to the sympathomimetics similar in structure. The biological half-life was about 2 h. After oral ingestion absorption was fast, the peak concentrations were observed between 1 and 2 h after administration.

[Successful treatment of a supraventricular re-entry tachycardia in a patient with WPW and sick-sinus syndrome with permanent rapid atrial and QRS-inhibited ventricular pacemaker stimulation (author's transl)].

A supraventricular re-entry tachycardia was successfully treated in a patient with WPW and sick-sinus syndrome by permanent rapid atrial pacing and ventricular demand pacing. The use of a demand pacemaker with bipolar electrode avoided slow ventricular rates resulting from second degree A-V block during rapid atrial pacing. The trigger system of this pacemaker was not disturbed by unipolar atrial stimulation. Ventricular rates responded satisfactorily to physical and to emotional stress as a result of improved A-V conduction in these circumstances. Rapid atrial pacing has prevented the re-entry tachycardia. In an emergency the atrial pacemaker can be inhibited by a magnet, but otherwise discharges permanently at a constant rapid rate.

[Clinical and pharmacokinetic studies in patients with digitalis intoxication (author's transl)].

6 patients with severe digitalis intoxication were studied while hospitalised in a coronary care unit. 2 and 4 patients had ingested high doses of lanatosid C and digoxin, respectively. In three cases ventricular arrhythmias, in one of these and two further cases SA blocking and an additional A-V-block in one case were observed. Maximum blood levels of digoxin between 3.4 and 20 ng/ml were determined several hours after the ingestion. The maximal blood levels were achieved in one patient only 52 h after ingesting lanatosid C and in one patient taking digoxin after 12.5 h. Potassium concentrations in plasma were elevated in 4 patients. Antiarrhythmic and electrolyte therapy is discussed and the usefulness of a stomach lavage for diminishing the quantity of absorbed lanatosid C is shown in one patient who had a maximal blood level of 3.4 ng/ml after taking 23.7 mg of lanatosid C. Cumulative urinary excretion of this patient was 0.68 mg within 5.5 days. This result confirms the minimal enteral absorption under the therapy chosen.
