    Description / Table of Contents: Zusammenfassung Die derzeit gebräuchlichen i.v. Gammaglobuline (GG) zerfallen im wesentlichen in zwei Gruppen: Gespaltene und ungespaltene Produkte. Gespaltene GG erhält man durch Pepsin- oder Plasmin-Behandlung, ungespaltene durchβ-Propiolacton-Stabilisierung, Säure-pH-4-Behandlung oder Polyäthylenglykol-Hydroxyäthylstärke-(PEG/HÄS)-Fällung. Die einzelnen Präparate unterscheiden sich in ihrer biologischen Aktivität (bestimmte Funktionen der Komplementaktivierung und Opsonisierung sind an die Fc-Struktur gebunden) sowie im Eliminationsverhalten (ungespaltene GG haben längere intra- und extravasale Halbwertszeiten). Während die Wirkung von GG in tierexperimentellen Studien gesichert erscheint, stehen für die meisten klinischen Indikationen kontrollierte Studien noch aus. Eine prospektive Studie an chirurgischen Risikopatienten ergab, daß die prophylaktische Gabe von hohen Dosen eines 7 S-GG die Häufigkeit septischer Komplikationen im post-operative Verlauf zu senken vermochte. Die Zukunft der GG-Therapie scheint in der Entwicklung eines größeren Spektrums von Hyperimmunglobulinen zu liegen.
    Notes: Summary The presently available i.v. gammaglobulines (GG) can be classified into two groups: Degraded and intact GG. Degraded GG are produced by pepsin or plasmin digestion. Intact GG are obtained byβ-propiolactone treatment, acidification at pH 4 or precipitation with polyethylenglycol-hydroxyethylstarch (PEG/HES). The various products have different characteristics with regard to their biological activity (certain functions of complement activation and opsonization are connected with the Fc structure) as well as their elimination (intact GG have longer intra-and extravasal half-life times). While their is no doubt about an effect of GG in animal experiments, little controlled studies have been done for most of the clinical indications. One controlled prospective study showed that in surgical high risk patients the frequency of septic complications can be reduced by prophylactic application of high doses of 7 S-GG. For the future, the development of a broad spectrum of hyperimmunoglobulines seems desirable.

    Notes: Summary Adverse reactions to foods are not infrequent. They may be mediated by immunological mechanisms (food allergy) or non-immunologically (idiosyncrasy, pseudo-allergy, intolerance). Furthermore toxic effects of foods have to be clearly distinguished from food allergy as well as poorly defined conditions such as hyperkinesis or “tension-fatigue syndrome”, the causal relation of which to foods is not well established. The diagnosis of food allergy includes convincing history, positive provocation and demonstration of immunological sensitization (mostly IgE, however other types of immune reactions may also be of importance). In the treatment of food allergy specific elimination diets as well as pharmacotherapy with the use of mast cell blocking agents are recommended. In single cases oral hyposensitization may be tried.

    Notes: Plasma histamine concentrations were determined using a radio-enzymatic assay in fifty-four patients suffering from atopic eczema and in thirty-nine controls (contact dermatitis, psoriasis and normal non-alopic healthy volunteers). While in none of the controls histamine levels in plasma exceeded 1 ng/ ml, seventeen out of fifty-four patients with atopic eczema showed increased plasma histamine concentrations ranging between 1-2 and 5′2 ng/ml. Elevated plasma histamine levels were found mostly in patients with severe eczema and high serum IgE. levels. Longitudinal studies in seven patients revealed normal plasma histamine values during clinical remission.

    Notes: The in vitro effect of levamisole (LMS) on lymphocyte, neutrophil, basophil and platelet function was investigated in patients with severe atopic dermatitis and hyper-immunoglobulinaemia E. Lymphocyte stimulation by several concentrations of PHA, con A and PWM, polymorphonuclear leukocyte chemotaxis and basophil histamine release were unaffected by LMS (10 μg/ml). Platelet serotonin release induced by iodipamide was decreased in patient and control groups by LMS but release induced by methacholine, epinephrine and thrombin was not.

    Notes: Two sisters (monozygotic twins) suffering from severe atopic eczema with pronounced seasonal exacerbation during spring and early summer were treated with subcutaneous injections of either grass pollen extract or saline. After 2 years of preseasonal treatment the skin symptoms improved significantly in the patient treated with grass pollen extract, while the placebo produced minimal change in her twin. The therapeutic effect was paralleled by a greater decrease in total scrum IgE (from 4,200 to 1,370 ku/l) in the pollen-treated patient (compared with 3,500 to 2,580 ku/l in the control twin).

    Notes: Abstract In a clinical study the participation of histamine in the allergenic response of patients with food allergy was investigated. The resting levels of gastric tissue and plasma histamines of 10 patients were slightly higher than the respective values of normal volunteers. 5 minutes after local intragastral allergenic provocation a decline of the mucosal histamine content of the allergen-treated area was noticed. Parallel investigations on the mast cell content of the stomach mucosa revealed a parallel decrease of theo-phthaldialdehyde stained cells, whereas the number of toluidine blue stained cells remained unchanged. These data are in accordance with an antigen-induced IgE-dependent liberation of the mast cell histamine stores.
