    Notes: Acantholysis occurring in rhesus monkey skin explants cultured on sera of 9 pemphigus patients was found to be largely dependent on the titre of intercellular antibody, and not on the participation of complement. Skin explants cultured on normal human sera and pemphigoid sera failed to give rise to intercellular staining or to develop lesions.Six of eight ‘negative’ pemphigus sera with intercellular antibody titres of less than 20 on skin (and titres ranging from 20 to 160 on monkey oesophagus) reacted with the skin explants as revealed by direct immunofluorescence with an anti-IgG conjugate. The binding of antibodies from 3 of these 6 reactive sera resulted in some pathological changes in the explants. At least two of these 3 ‘negative’ sera came from pemphigus patients with skin lesions.

    Notes: A survey of 234 cases of pemphigus yielded three observations which suggest that different forms of pemphigus may have different etiologies.1. While the incidence of pemphigus in the age group of 21 and over was essentially the same in males and females (108 and 113) the incidence was significantly higher in females in the age group under 20. Only two of 13 patients in this group were males. Also pemphigus foliaceus and erythematosus was reported in a significantly higher proportion of the cases in the age group of 2 1/2 to 20 thus suggesting that the juvenile form of the discase differs from the adult form.2. In four of a group of 15 cases identified as pemphigus foliaceus the disease appeared to be provoked by minor physical insults, a frequency which is significantly higher than the five cases with similar histories in the group of 198 cases identified as pemphigus vulgaris.3. In the entire group of 234 cases two patients with pemphigus both proven by immunofluorescence had relatives with pemphigus. Also a third patient had a blood relative with bullous pemphigoid. This frequency of three per 234 is higher than would be expected by chance. Studies of one family (not included in this survey) with multiple skin antibodies suggest that such familial predispositions may be due to abnormal immune responses.

    Notes: : A patient with the clinical features of dermatitis herpetiformis and the histological features of pemphigus, subcorneal dermatosis and dermatitis herpetiformis did not respond to treatment with pyridine or sulfones. Systemic steroids and azothioprine were effective. Immunofluorescence studies demonstrated circulating pemphigus antibodies and IgG bound in vivo in the intercellular spaces of the epidermis.

    Description / Table of Contents: Zusammenfassung Immunofluorescenz-Beobachtungen sind diagnostisch bedeutsam bei Herpes gestationis. Untersuchungen bei zwei Patienten zeigten, daß Complement-Komponente (im wesentlichen C3 und C4, nicht aber C1q) bei fehlenden Immunglobulinen an der Basalmembranzone (BMZ) nachweisbar waren. Circulierende Anti-BMZ-Antikörper fehlten. In einer Biopsie war IgG an der Basalmembranzone sichtbar, weitere Gewebsentnahmen waren jedoch negativ. Die Ergebnisse der Immunfluorescenz lassen den alternierenden und den klassischen Weg der Complementaktivierung vermuten. Sie weisen auf eine Beziehung zwischen Herpes gestationis und bullösem Pemphigoid hin. Auch bei der letzteren Erkrankung sind Immunglobuline gelegentlich nicht nachweisbar, und das Immunfluorescenzbild wird dem des Herpes gestationis ähnlich.
    Notes: Summary Immunofluorescence findings are of diagnostic significance in herpes gestationis. The studies in two cases demonstrated some complement components (chiefly C3 and C4, but no C1q), without immunoglobulins at the basement membrane zone and with no circulating anti BMZ antibodies. In one case IgG were found at the BM zone in one biopsy specimen, but were not demonstrable in several other biopsies. The IF findings seem to indicate both the alternate and classical pathways of complement activation, and speak in favor of a relation between herpes gestationis and bullous pemphigoid, in which sometimes the immunoglobulins are also not demonstrable and the immunofluorescent pattern is very much like that of herpes gestationis.

    Description / Table of Contents: Zusammenfassung Immunofluorescenz(IF)-Untersuchungen mittels der Methode, die die Feststellung von Stratum corneum Antikörper im Serum und ihre in vivo-Fixierung ermöglicht, wurden bei 193 Psoriasis-Fällen und 89 Kontrollpersonen durchgeführt. Es wurde nachgewiesen, daß: 1. Im allgemeinen alle völlig entwickelten, aktiven Psoriasisläsionen IgG-Ablagerungen im Stratum corneum an den Antigenseiten, angeblich in Folge ihrer in vivo-Fixierung, enthalten. 2. In verschiedenen Psoriasisabarten waren die Antigenseiten des Stratum corneum völlig oder fast völlig von in vivo-fixierten IgG-Ablagerungen gesättigt, was man im Vergleich mit der Intensität der in vitro-Reaktion mit SC-Antikörpern aufzeigen konnte. 3. In der Mehrheit, aber nicht in allen Hautveränderungen waren die Komponente 3 und 5 des Komplements in vivo-fixiert und hatten ein gleiches IF Pattern wie IgG, besonders wenn man mehrere Biopsien in einzelnen Fällen durchführte. Eine teilweise oder komplette Sättigung konnte im Vergleich mit der Intensität der in vitro-Komplement-Reaktion festgestellt werden. 4. In allen Hautveränderungen mit typischem histologischem Bild von Psoriasis waren die IF-Befunde charakteristisch. Jedoch in manchen sehr frühen Psoriasisläsionen mit noch nicht gänzlich charakteristischem histologischem Bild wurden weder IgG noch Komplement festgestellt (in 2 von 17 Fällen).In zurücktretenden Läsionen waren schwache IgG-Ablagerungen nur in einzelnen Biopsien vorhanden und das Komplement war in der Regel nicht feststellbar. 5. In der Kontrollgruppe von 89 Fällen hatten nur einzelne Biopsien das psoriasis-ähnliche IF-Pattern, jedoch in ungefähr 30% der Biopsien wurden manche Ablagerungen im Stratum corneum festgestellt, obwohl sie ein unterschiedliches IF-Muster hatten.
    Notes: Summary Immunofluorescence (IF) studies using the test providing information on the reactivity of stratum corneum (SC) antibodies and their in vivo binding have been performed in 193 cases of psoriasis and 89 cases with other dermatoses. It has been shown that: 1. Essentially all fully developed, active psoriatic lesions had IgG deposits in the stratum corneum at the sites of the SC antigen, presumably due to in vivo binding of SC antibodies. 2. In various forms of psoriasis SC antigen sites appeared to be completely or almost completely satured with in vivo deposits of IgG as seen in tests with SC antibodies. 3. In most but not all lesions complement components C3 and/or C4 was found in a comparable pattern in the SC, especially when multiple specimens of single cases were studied. Partial or complete saturation of the SC antigen could be observed by the performance of complement indirect IF tests for SC antibodies in such specimens. 4. In lesions with typical histology of psoriasis the above-mentioned immunologic characteristics appeared to be a constant finding. However, in specimens of recent lesions which had not yet developed typical histology a proportion (2 of 17) were negative both for IgG and complement deposits. In receding lesions weak deposits of IgG were present only in a few specimens and complement deposits were as a rule negative. 5. cIn a group of 89 control specimens of other dermatoses only occasional cases gave the psoriasiform IF pattern, but about 30% of the specimens gave positive reactions in the SC though these were usually of a different pattern.

    Description / Table of Contents: Zusammenfassung Antikörper gegen Stratum corneum (SC) befinden sich in Seren aller Menschen und können mittels der indirekten Immunofluorescenzmethode festgestellt werden. In Psoriasis-Herden scheinen sie in vivo im Stratum corneum fixiert zu sein. Sie fixieren Komplement in vitro, was man durch Komplement-Fixierungs-Tests unter Benutzung von anti C4 oder anti C3 Konjugaten beweisen kann. IF-Teste mit unterschiedlichen Kontrollen haben aufgezeigt, daß Stratum corneum als Antigen in Psoriasis-Läsionen nicht nur von IgG, sondern in der Mehrheit der Veränderungen auch von Komplement umgeben ist. In völlig entwickelten Läsionen wurde das Komplement in 88% der Biopsien festgestellt, weniger häufig — in ungefähr 50% — in sehr frühen linearen Hautveränderungen vom Typ des zufälligen Köbnerschen Phänomens. Diese und frühere Beobachtungen erbrigen einen indirekten Beweis, daß Antikörper SC an der Entstehung der Psoriasisherde teilnehmen, und die Komplementfixierung hier von Bedeutung sein könnte.
    Notes: Summary The stratum corneum (SC) antibodies are present in all human sera as seen by indirect immunofluorescent (IF) staining. They appear to bind in vivo to the stratum corneum of psoriatic lesions. They fix complement in vitro in a two step complement IF test system using either anti C4 or anti C3 conjugates as indicators. IF tests with proper controls showed that the SC antigen in psoriatic scales is coated not only with IgG but in a majority of the lesions also with complement. In the present studies in fully developed lesions complement was detectable in 88% of the specimens studied and in about 50% of very fresh linear lesions of unintentional Köbner type. These as well as some previously published observations afford indirect evidence for the participation of SC antibodies and the ensuing fixation of complement in the development of psoriatic lesions.
