    Notizen: Although the precise aetiology of lichen sclerosus is unknown, evidence for an autoimmune basis to the disorder is emerging. Indeed, circulating IgG autoantibodies to the glycoprotein extracellular matrix protein 1 (ECM1) have been demonstrated in the sera of about 75% of affected individuals. To assess this humoral immune response further, immunoblotting was performed using bacterial recombinant proteins spanning different domains of the ECM1 protein. The aim was to identify autoantibody-reactive sites recognized by 90 lichen sclerosus sera. The subclass distribution of anti-ECM1 IgG autoantibodies was also determined in 54 lichen sclerosus sera. Immunoblotting showed that the IgG autoantibodies from lichen sclerosus patients recognize multiple antigenic reactive sites on the ECM1 protein within both the amino terminus (50/90, 55.6%) and the protein loop cysteine-rich repeat domains (54/90, 60%), although few sera (7/90, 7.8%) had antibodies to the carboxyl terminus of ECM1. IgG subclass analysis revealed that the anti-ECM1 autoantibodies belong predominantly to the IgG2 subclass (48/54, 88.9%), either IgG2 alone (28/54, 51.9%) or in combination with one or more other IgG subclasses. No correlation was found between the site(s) of the ECM1 epitopes or the anti-ECM1 IgG profile and any specific clinical parameters. Nevertheless, characterization of anti-ECM1 antibodies does provide further insight into humoral immune responses and understanding disease mechanisms in lichen sclerosus.

    Widespread morphoea following radiotherapy for carcinoma of the breast (2003)
    Oxford, UK : Blackwell Science Ltd

    Notizen: Summary We report a case of a 60-year-old lady who was treated with radiotherapy for breast cancer of both breasts 8 years apart. Thirteen years after the first dose of radiotherapy she developed localized morphoea in all the irradiated skin of the chest wall and also the gaiter regions of both lower legs. Radiation-induced localized morphoea has been previously reported; however, there is no previous publication of an occurrence at a distant site as in this case. This case demonstrates that morphoea can occur distant to the original breast carcinoma and site of radiotherapy. We postulate that radiotherapy can induce neoantigen formation, which initiates a T cell response and subsequent tissue growth factor α release. Tissue growth factor α induces fibroblast activation and collagen production may persist due to a positive feedback mechanism within the fibroblast. The reason why the disease did not generalize remains unclear.

    Notizen: John Laws Milton, a 19th-Century surgeon, founded the St John's Hospital for Diseases of the Skin close to Leicester Square in London in 1863. This article reviews his single-minded effort to establish dermatology as a medical subspeciality and to create a proper skin diseases hospital. The review also details his many contributions to the medical and dermatological literature, including his insightful description of the pregnancy dermatosis, herpes (pemphigoid) gestationis.

    Psoriasis bullosa acquisita (2002)

    Notizen: Summary We report a 51-year-old man with a 20-year history of chronic plaque psoriasis who developed an autoimmune subepidermal blistering eruption that had clinical features of bullous pemphigoid, erythema multiforme and epidermolysis bullosa acquisita. Investigations revealed a 1 : 400 titre circulating and in vivo bound IgG autoantibody that mapped to the dermal side of 1 m NaCl-split skin and localized to the lower lamina lucida/upper lamina densa on immunogold electron microscopy. Immunoblotting, using dermal extracts, showed serum binding to antigens of ≈ 200- and ≈ 260 kDa. Indirect immunofluorescence microscopy, using the patient's serum on archival skin sections taken from selected individuals with different forms of inherited epidermolysis bullosa as substrate, showed normal basement membrane labelling on all samples apart from recessive dystrophic epidermolysis bullosa skin (with inherent mutations in the type VII collagen gene): in these cases there was a complete absence of immunostaining. Clinically, the patient responded rapidly to combination treatment with intravenous immunoglobulin and oral corticosteroids, dapsone and mycophenolate mofetil. Autoimmune subepidermal blistering has been reported in other patients with psoriasis, although no specific target antigen has ever been determined. Our study provides preliminary evidence that, for this patient at least, the autoantibody may be targeted against a skin component closely associated with type VII collagen (the epidermolysis bullosa acquisita antigen). Therefore, we propose the term ‘psoriasis bullosa acquisita’ for this and possibly other patients with similar skin eruptions.

    Dermatitis herpetiformis evolving into bullous pemphigoid: a probable example of ‘epitope spreading’ (2000)

    Notizen: We report a case of dermatitis herpetiformis which, 11 years after its original diagnosis, evolved into bullous pemphigoid. Only a few similar cases supported by immunfluorescence studies have been reported previously, and we believe that they represent examples of ‘epitope spreading’, an increasingly recognized phenomenon used to explain the coexistence of autoimmune diseases.

    Bullous subacute cutaneous lupus erythematosus (2004)

    Thema: Medizin
    Notizen: We describe a 59-year-old woman, with a history of autoimmune disease and disseminated uterine leiomyosarcoma, who developed a photoaggravated, blistering skin eruption. An initial rash, at the outset of treatment with chemo- and radiotherapy, resembled erythema multiforme. Review of the original skin biopsy showed it to be subacute cutaneous lupus erythematosus. There were no systemic symptoms or signs to suggest systemic lupus erythematosus. The much later photoaggravated rash consisted mainly of bullae and eventual epidermal denuding which resembled toxic epidermal necrolysis. We propose that the clinical and histological diagnosis is one of bullous subacute cutaneous lupus erythematosus in a patient with no other features of systemic lupus erythematosus.

    Collagen XVII/BP180: a collagenous transmembrane protein and component of the dermoepidermal anchoring complex (2005)

    Thema: Medizin
    Notizen: Collagen XVII, or BP180, is a collagenous transmembrane protein and a structural component of the dermoepidermal anchoring complex. Molecular studies reveal that it has a globular cytosolic amino-terminal domain and flexible-rod extracellular carboxyterminal domain. The extracellular portion of collagen XVII is constitutively shed from the cell surface by ADAMs (proteinases that contain adhesive and metalloprotease domains). Cell biological analyses suggest that collagen XVII functions as a cell–matrix adhesion molecule through stabilization of the hemidesmosome complex. This concept is supported by investigations into human diseases of the dermoepidermal junction, in which collagen XVII is either genetically defective or absent (as in some forms of nonlethal junctional epidermolysis bullosa). Autoantibodies against collagen XVII (BP180) are seen in bullous pemphigoid, pemphigoid gestationis, mucous membrane pemphigoid, linear IgA disease, lichen planus pemphigoides and pemphigoid nodularis. In vivo and in vitro studies provide evidence for a pathogenic role of these autoantibodies, and suggest that the serum level and epitope specificity of these antibodies influences disease severity and phenotype. This review summarizes the structural and biological features of collagen XVII and its role in diseases of the basement membrane zone.
