    Notes: Background Epidemiological evidence underlines the impact of prenatal environmental factors on the development of postnatal allergies. In this regard an inverse correlation between lipopolysaccharide (LPS) exposure and development of childhood allergy has been found.Objective To assess the impact of prenatal LPS exposure on the development of postnatal respiratory allergies in a mouse model of experimental asthma.Methods Female BALB/c mice were exposed to LPS before conception and during pregnancy. Several weeks after birth offspring were sensitized to ovalbumin (OVA) followed by aerosol allergen challenges.Results Prenatal, maternal LPS-exposure enhanced neonatal IFN-γ, but not IL-4 and IL-2 production. OVA sensitization of prenatally LPS-exposed mice was accompanied by a marked suppression in anti-OVA IgG1 and IgE as well as unchanged IgG2a antibody responses, paralleled by a significant reduction in IL-5 and IL-13 levels following mitogenic stimulation of splenic leucocytes. Assessment of bronchoalveolar lavage fluids following allergen challenges revealed a marked reduction in eosinophils and macrophages in these mice. Surprisingly, development of airway hyper-responsiveness, a hallmark of bronchial asthma, was not affected.Conclusion This study provides first experimental evidence that LPS may already operate in prenatal life in order to modulate the development of allergies in the offspring.

    Notes: Background and aim Atopic dermatitis (AD) is a common chronic inflammatory skin disease often accompanied by cutaneous Staphylococcus aureus colonization and, in this regard, especially complicated by the presence of superantigen-producing strains. Because IgG antibodies comprise an important defence mechanism of the adaptive immune system against bacteria, it was investigated whether AD patients have an abnormal pattern or distribution of superantigen-specific IgG subclass antibodies in association with disease severity and activity.Methods Staphylococcal enterotoxin B (SEB) and staphylococcal enterotoxin C1 (SEC1) specific IgG antibody subclasses were assessed in n=89 adult AD patients with mild to severe disease activity as determined by the SCORAD score and in n=28 healthy age-matched controls. Results were correlated with the current status of bacterial skin colonization and severity score.Results Thirty-eight per cent of the AD patients showed a selective deficiency in IgG2 antibodies against SEC1 compared with only 14% in the control group. The absence of these antibodies was found in both currently colonized and non-colonized AD patients and was associated with a severe phenotype (SCORAD more than 40 points in two-thirds of the deficient patients). However, these patients had normal production levels of IgG2 antibodies against pneumococcal capsular polysaccharide (PCP) and SEB, but higher IgG1 and IgG4 titres against SEC1. Except for elevated total IgG1, total IgG subclass levels were normal in this AD subgroup. Yet, peripheral blood mononuclear cells (PBMCs) derived from these patients clearly produced IL-4 and IL-5 upon SEC1 re-stimulation whereas PBMCs from those providing SEC1-specific IgG2 antibodies failed in the production of these cytokines.Conclusion A subgroup of AD patients suffers from a selective deficiency to produce anti-SEC1 IgG2 antibodies. This patient group is characterized by a severe AD phenotype.

    Notes: Background Bronchial asthma is characterized by chronic airway inflammation and airway remodelling which occurs in both proximal and distal airways. These changes are associated with development of airway hyper-responsiveness and airflow limitation.Objective This study was aimed to analyse whether chronic inhalative allergen challenges in mice lead to morphological and physiological changes comparable with this phenotype.Methods For this purpose, BALB/c mice were systemically sensitized to ovalbumin (OVA) followed by aerosol allergen challenges on 2 consecutive days per week for 12 weeks.Results In chronically challenged mice, tissue inflammation in proximal as well as distal airways was observed with a predominance of lymphocytes within the cellular infiltrate. In contrast, inflammation in the airway lumen decreased over time. These changes were associated by a shift in bronchoalveolar lavage–cytokine levels from IL-4, IL-5 and TNF-α production (during the acute phase) towards markedly increased levels of TGF-β during the chronic phase. Goblet cell hyperplasia and subepithelial fibrosis occurred throughout the airway tree. In terms of lung function, chronically challenged mice developed persistent bronchial hyper-responsiveness and progressive airflow limitation. Six weeks after OVA aerosol discontinuation, airway inflammation still persisted although lung function was normalized.Conclusion These data indicate that our model of chronic aerosol allergen challenges leads to a phenotype of experimental asthma with participation of distal airways and persistence of inflammation thereby resembling many morphological and physiological aspects of human bronchial asthma.

    Description / Table of Contents: Zusammenfassung Es wird ein Fall von Dysgammaglobulinämie Typ I (Einteilung nach Rosen und Janeway [20]) mitgeteilt. Der 7jährige Knabe zeigte die typischen Zeichen eines Antikörpermangelsyndroms seit seinem ersten Lebensjahr. Die Acetatfolienelektrophorese war unauffällig, trotzdem fehlten bei dem Patienten IgG und IgA vollständig. Erst die immunelektrophoretische Analyse deckte den Defekt auf: Eine im β2-Bereich nachweisbare Doppellinie entsprach zwei verschiedenen Typen von IgM-Molekülen, nämlich IgM-kappa und IgM-lambda, wie durch entsprechende Erschöpfung des Antiserums mit Bence-Jones-Proteinen vom kappa- und/ oder lambda-Typ gezeigt werden konnte. Die analytische Ultrazentrifugation und die Gelfiltration über Sephadex G 200 bestätigte das Vorliegen einer polyklonalen Makroglobulinämie, der Serum-IgM-Gehalt betrug etwa 880 mg/100 ml (Ergebnis der Ultrazentrifugation). Das exzessiv vermehrte IgM erschien inert, es konnten keine Isoagglutinine nachgewiesen werden.
    Notes: Summary A case of dysgammaglobulinaemia type I (according to Rosen and Janeway [20]) is reported. Since his first year of life, a seven year old boy suffered from symptoms typical of an antibody deficiency syndrome. Paper electrophoresis was normal, but IgG and IgA were completely missing. The defect was finally analysed by immune electrophoresis: A double band in the region of β2 corresponded to two different types of IgM molecules, namely kappa and lambda, as could be demonstrated by exhaustion of the antisera with Bence-Jones proteins of the kappa- and lambda-type. Macroglobulinaemia was confirmed by analytical ultracentrifugation and Sephadex G-200 gel filtration. The serum IgM level was approximately 880 mg/100 ml. Isohemagglutinins however were absent. It was concluded that the excessively increased IgM was functionally inert.
