    Notes: : The frequency of HLA-class l and DR antigen frequencies were studied in 38 (class 1) and 19 (DR) patients with bullous pemphigoid, respectively, and compared with controls. There was no important difference in the frequency of HLA-A,B,C and DR antigens between patients and controls. An increase in the HLA-B7 frequency in poor responders to immunosuppressants (50% vs. 27% in the control group and vs. 13% in the group of all patients) was noticed, and the possible role of this antigen as a marker for poor responders to therapy was suggested.

    Notes: Summary Expression of interleukin-2 (IL2) receptors was studied on peripheral blood lymphocytes (PBLs) in 25 patients with bullous pemphigoid. Analysis was carried out by flow cytometry. Without immunosuppressive therapy expression of IL2 receptors only on T cells (CD5) was significantly increased as shown by double staining (11.9%±7.8% vs 2.1%±1% in controls). After 2–3 weeks under immunosuppressive treatment with prednisolone and azathioprine, however, BP lymphocytes did not exhibit any IL2 receptors. PBLs of 18 BP patients showed an increase in IL2 production (1027.4±670.5 U/ml vs 270±100 U/ml in controls) during the acute stage of the disease after stimulation with phythaemagglutinin (PHA)/ phorbol myristate acetate (PMA). On the contrary, IL2 production of the same cells in five patients was only in the lowest range of control values after PHA stimulation without PMA (12.5±29.6 U/ml vs 40±20 U/ml in controls). Under treatment with immunosuppressants the IL2 production normalized after PHA/PMA stimulation and slightly decreased following PHA stimulation. From these results we conclude that a T-cell activation via activation antigens, as IL2 receptors, and the production of the specific ligand, IL2, may play a role in the pathogenesis of bullous pemphigoid, especially in the earliest stages, and serve as a marker of disease activity.

    Description / Table of Contents: Summary. Thirty strains of the lipophilic yeast Pityrosporum ovale were isolated from patients suffering from seborrhoeic dermatitis and dandruff and tested for susceptibility both to some classic antifungal agents and to several primarily non-antimycotic drugs. Minimal inhibitory concentrations (MIC) of altogether eleven agents were measured by the agar dilution technique. As expected, the tested imidazoles showed a good inhibition of growth of Pityrosporum. The most effective agents were ketoconazole (MIC 0.1 µg/ml) and itraconazole (MIC 0.05 µg/ml for some strains). MIC for fluconazole, clotrimazole and tioconazole were also low, indicating a good inhibition of Pityrosporum. In contrast, the range of MIC for bifonazole was moderate to high (for some strains 12.5 – 25 µg/ml). For zinc pyrithion a very good in vitro efficacy (MIC 0.78 – 1.56 µg/ml) was dedicated. The MIC for selenium disulphide was 1.56 – 3.13 µg/ml. The antipsoriatic drugs dithranol and liquor carbonis detergens also inhibited growth of all Pityrosporum ovale strains investigated but only at higher concentrations.
    Notes: Zusammenfassung. Von Patienten mit seborrhoischer Dermatitis und Kopfschuppen wurden 30 Pityrosporum ovale-Stämme isoliert und deren In-vitro-Empfindlichkeit sowohl gegenüber verschiedenen klassischen Antimykotika, als auch gegen einige antiseborrhoische und antipsoriatische Wirkstoffe getestet. Für die Ermittlung der minimalen Hemmkonzentration (MHK) wurde ein Agardilutionstest eingesetzt. Wie zu erwarten war, hemmten die getesteten Imidazolderivate das Wachstum von Pityrosporum ovale in vitro gut. Den besten Hemmeffekt hatten Ketoconazol (MHK 0,1 µg/ml) und Itraconazol (MHK-Werte von 0,05 µg/ml für einige Stämme). Aber auch die MHK-Werte der anderen untersuchten Azole Fluconazol, Tioconazol und Clotrimazol sowie des Polyen-Antimykotikums Natamycin waren niedrig, was ebenfalls für eine gute Hemmwirkung gegenüber Pityrosporum spricht. Zink-Pyrithion wies eine sehr gute Wirksamkeit gegen Pityrosporum ovale auf (MHK 0,78 – 1,56 µg/ml). Die MHK-Werte von Selendisulfid lagen im Bereich von 1,56 bis 3,13 µg/ml. Eine Wachstumshemmung von Pityrosporum konnte auch durch die Antipsoriatika Dithranol und Steinkohlenteer erzielt werden; es waren dafür jedoch höhere Wirkstoffkonzentrationen erforderlich.

    Notes: Abstract The antibacterial activity of the topical quinolone OPC-7251 against bacteria commonly found in acne vulgaris was tested in vitro by an agar dilution method. The MIC50 was 0.25 mg/l forPropionibacterium acnes, 0.125 mg/l forPropionibacterium granulosum, 0.03 mg/l forStaphylococcus aureus and 0.06 mg/l for coagulase-negative staphylococci. Compared with seven other antibiotics tested (ciprofloxacin, penicillin, erythromycin, tetracycline, clindamycin, fusidic acid and gentamicin), OPC-7251 had potent activity against both propionibacteria and staphylococci and the lowest incidence of resistant strains.
