    Description / Table of Contents: Summary Pharmacologically or immunologically induced hypersensitivity to penicillin is frequent. Immunological, i.e., allergic, hypersensitivity reactions are among the most important side effects and can lead to severe and life-threatening reactions. All types of allergic reactions have been described secondary to penicillin therapy. Immediate type hypersensitivity reactions, the symptoms of which range from urticaria and angioedema to respiratory and cardiovascular symptoms, and finally to life threatening full anaphylactic shock are particularly dangerous. This case-report demonstrates that in a patient allergic to penicillin, in whom there is a vital indication to administer this compound, the drug can be given safely after tolerance induction.
    Notes: Zusammenfassung Pharmakologisch oder immunologisch bedingte Unverträglichkeitsreaktionen gegenüber Penicillinen sind häufig. Immunologische, also allergische Überempfindlichkeitsreaktionen gehören zu den wichtigsten Nebenwirkungen und können zu schweren und z.T. lebensbedrohlichen Reaktionen führen. Prinzipiell sind durch Verabreichung von Penicillinen alle Formen allergischer Reaktionen möglich. Besonders gefürchtet sind Soforttypreaktionen, deren Symptome von Urtikaria und Quincke-Ödem über leichte Atemnot und Herz-Kreislauf-Reaktionen bis hin zum lebensbedrohlichen anaphylaktischen Schock reichen. Mit dem hier dargestellten Fallbericht soll gezeigt werden, daß bei wichtiger Behandlungsindikation die Anwendung von Penicillin auch bei Patienten mit Penicillinallergie nach Toleranzinduktion möglich ist.

    Notes: Background: Hyposensitization with bee venom leads to full protection in most, but not all patients with IgE-mediated systemic reactions to bee stings.Objective: To determine the relationship of clinical reactivity to the release of mediators and to changes of antibody concentrations in the peripheral circulation at a bee sting challenge test.Methods: Blood was sampled before (0 min) and at 15, 60 and 180 min after a sting challenge from 19 patients on hyposensitization. Of these, six still reacted and 13 were protected. Histamine, mast cell tryptase, bee venom-specific IgE and IgG in the serum, and histamine release from peripheral blood leucocytes (PBL) upon exposure to bee venom were determined.Results: Tryptase above the detection level was found only at 15 (60)min in 4/6 (1/6) patients who reacted. After the sting challenge there was a significant increase of the histamine levels in patients who reacted at 15 min (P 〈 0.05) and in patients who did react at 60 and 180 min (P 〈 0.01). The total histamine content of PBL was significantly decreased after 15 and 60 min in patients who reacted (P 〈 0.01) and in those that did not (P 〈 0.05). Bee venom-induced histamine release was significantly reduced in patients reacting and those that did not at 15 min (P / 0.05), and was significantly decreased in reactors also at 60 and 180 min (P 〈 0.05/0.01). Specific IgG antibodies showed a minor decrease (P 〈 0.05) after the sting challenge in both groups, whereas specific IgE did not change significantly.Conclusion: These results indicate that bee venom anaphylaxis is associated with the release of mediators from both mast cells as well as basophils. Successful hyposensitization does not induce a state of immunological non-reactivity, but rather alters the magnitude and the pattern of mediator release.

    Notes: Background Disturbances of β2-adrenoceptors are discussed as a pathogenic factor in atopic diseases.Methods In this study tbe expression and function of β2-adrenoceptors on peripheral blood leucocytes (PBL) of seven atopic patients with seasonal rhinoconjunctivitis and their seven healthy controls was evaluated in relation to disease activity. Earlier reported data during pollen. season were now compared with data obtained from the same subjects after their allergic symptoms had subsided.Results The variables that had indicated a β2-adrenoceptor subsensitivity in tbe patients during pollen season returned to control values, i.e. the reduced β2-adrenoceptor affinity, the reduced β2-adrenoceptor sensitivity, the reduced increase of intracellular cyclic adenosine monophosphate (cAMP) content upon stimulation with isoproterenol, and the reduced cAMP plasma concentration (values no longer significantly different from those of controls). However, the variable that had suggested an increase in activity of the cAMP degrading enzyme phosphodiesterase (PDE), i.e. the reduced basal intracellular cAMP content of the patients, remained reduced after the pollen season (4.9 ± 1.1 pmol/lO6’cells in patients vs 8.2 ± 0.9pmol/106 cells in controls: P 〈 0.05). There were no significant differences in β2-adrenoceptor density between patients and controls at both investigations.Conclusions Atopic seasonal rhinoconjunctivitis is associated with various alterations in the PBL β2-adrenoceptor/cAMP system that depend on disease activity. The reversible β2-adrenoceptor subsensitivity is likely to be a consequence of the disease, whereas the irreversibly decreased basal intracellular cAMP content, suggested an elevated PDE activity, might be a basic trait of atopy.

    Notes: Summary Basalomalosis is an uncommon skin condition characterized by the occurrence of multiple basal cell carcinomas. Many cases reported in the literature have been attribuled to arsenic treatment in psoriasis patients. We report a patient with basalomatosis caused by cobalt-60 (60Co) irradiation. A 55-year-old farmer developed 43 basal cell carcinomas 20 years after treatment of an immuno-blastoma with 60Co irradiation. All the tumours were located within the radiation fields. Other possible causes of basalomatosis, such as arsenic intoxication and basal cell naevus syndrome, were excluded. The patient's multiple superficial basal cell carcinomas probably represent a late adverse effect of the 60 irradiation.

    Notes: Immediate-type allergy to natural rubber latex (NRL) is common in highly exposed groups, particularly in health-care workers and patients with spina bifida. The occurrence of NRL allergy was investigated in subjects not belonging to such risk groups. A total of 493 patients presenting with various diseases for allergologic evaluation was studied. A questionnaire-based history was taken, skin prick tests with NRL milk and common aeroallergens were done, and NRL-specific serum IgE antibodies were measured. A total of 317 subjects (64.3%) was atopic. There were skin prick test reactions to NRL in 80 (16.2%) and NRL-specific IgE in the serum in 79 (16.0%) subjects; both were found in 25 patients (5.1%). Altogether, NRL sensitization was found in 134 patients (27.2%). By history and/or challenge tests. 13 subjects (2.6%) were diagnosed as having clinically relevant NRL allergy. In five of these, anaphylactic reactions had occurred during dental procedures, and in four during general anesthesia; 10 subjects reported immediate-type reactions to NRL products in daily life. AU patients with clinically relevant NRL allergy had a skin prick test reaction to NRL milk (sensitivity 100%). Nine had specific IgE antibodies in the serum (sensitivity 69.2%); respective specificity was 86.0% or 85.4%. Nine of the 13 patients (69.2%) with NRL allergy were atopic. Despite exclusion of those at risk, many patients had clinically relevant allergy to NRL, and many of these had had severe reactions. NRL allergy is an important health issue also beyond the known risk groups.

    Notes: Determination of Hymenoptera venom (HV)-specific serum IgE antibodies is a useful diagnostic method in patients with systemic anaphylactic reaction (SAR) to Hymenoptera stings. In a general population cohort, we determined the prevalence of SAR and HV-specific IgE antibodies and assessed parameters associated with the latter. A total of 277 voluntarily participating inhabitants of rural Bavaria (Germany) (232 adults, mean age 38.0 years; 45 children, mean age 8.4 years) were investigated for a history of atopic disease or SAR to insect stings; in 258 of these, total IgE and specific IgE antibodies to HV (Apis melliferu, Vespulu vulguris/germanica) and four common aeroallergens (birch pollen, grass pollen, house-dust mite, and cat dander) in the serum were determined. Nine (3.3%) subjects reported SAR to insect stings. In 27.1% of the sera, specific IgE antibodies to HV were found, to bee venom in 24.8%, and to wasp venom in 8.5% (P〈0.000l) Of those exhibiting HV-specific IgE, 7.1% reported SAR to insect stings. A personal history of atopic disease (hay fever, asthma, or atopic eczema) was present in 16.7%, specific IgE to common aeroallergens was found in 32.6%, and total IgE〉 100 kU/1 was found in 22.5%. Specific serum IgE to HV was significantly associated with male sex (female vs. male, OR =0.47; CI 0.25-0.86), young age (children vs. adults, OR =2.80; CI 1.25-6-28), a history of SAR to insect stings (OR=4.16; CI 1.15-15.03), total sIgE〉 100 kU/1 (OR=3.88; CI 1.98-7.60), and specific IgE antibodies to three of the four aeroallergens (grass pollen, OR = 7.24 CI 3.66-14.38; birch pollen, OR=3.67 CI 1.54-8.81; and house-dust mite, ORz4.61 CI 2.08–10.32). It is concluded that immunologic sensitization to HV is common in the general population and is associated with atopy-related I humoral IgE hyperresponsiveness.

    Notes: The efficacy and tolerance of short-term immunotherapy (STI) by seven preseasonal injections of tree-pollen allergens (ALK7 FrUhbltihermischung®) was investigated in a double-blind, placebo-controlled, multicenter study with 111 rhinoconjunctivitis patients. Nasal and bronchial symptoms simultaneously analyzed, and nasal symptoms as a single end point, but not the overall score of nasal, bronchial, and conjunctival symptoms, showed a significantly lower increase with STI during birch-pollen exposure (both P= 0.033, n= 105, Mann-Whitney U-test). However, a selective analysis with patients from centers with high recruitment figures (nS10 patients, n=29 STI, n=32 placebo) showed a significantly lower increase of nasal, bronchial, and overall symptom score (STI 11.0 vs placebo 18.0, P=0.001, U-test). STI had equidirected effects on conjunctival, nasal, and bronchial symptoms analyzed as multiple end points, although conjunctival symptoms were not significantly different as a single end point. The seasonal increase in drug use was reduced by 62% in the STI group compared with placebo (P=0.032, Mest), Specific IgG4 increased only after STI (P〈0,001); IgE was not significantly different. Eosinophil cationic protein remained unchanged with STI, but significantly increased with placebo in the pollen season (P=Qm3). STI was well tolerated. In conclusion, STI was shown to be efficacious and safe for the treatment of patients with tree-pollen rhinoconjunctivitis.
