Two immunohistochemical methods, using the enzyme horseradish peroxidase, the direct immunoperoxidase (DIP) and the immunoglobulin-enzyme bridge (IEB) method were applied on 129 skin specimens of 81 patients with lupus erythematosus, bullous pemphigoid, pemphigus vulgaris and rosacea. These methods were compared with each other and with the immunofluorescence (IF) method. The DIP method was preferred to the IEB method because of the greater contrast between the specific staining and the nonspecific staining of the former. The results obtained with both peroxidase methods were comparable with those of the IF method.

Reagents and equipment are now readily available to make fluorescent antibody techniques routine diagnostic procedures. Antinuclear antibodies are detectable by such methods and are useful in the diagnosis of autoimmune disease. By defining not only the site of tissue damage but also the specific components deposted at that site, immunofluorescence applied to renal biopsies has helped to elucidate the nature of otherwise similar appearing processes. Fluorescent techniques also facilitate diagnosis of such skin diseases as lupus, bullous pemphigoid and pemphigus.

Immunofluorescence studies were made by the indirect method in 54 cases of pemphigus erythematosus, in 50 of which skin specimens from light-exposed and unexposed regions were investigated also by the direct IF method. IF Band was shown to be demonstrable in skin specimens from exposed regions in 81% of cases and from unexposed regions in 23%. ANA were found in some 31% of patients, though usually in titers below those of IC antibodies. There were 2 cases each of coexistence with myastenia gravis and thymoma and with SLE. Virus-like particles, however, were found by electron microscopy only in 1 case with coexisting SLE. Detection of IF Band in skin specimens from a significant majority of patients with pemphigus erythematosus, presence of ANA in some, and occasional coexistence of SLE suggest some relation of the disease with lupus erythematosus.

A simple technique using immunoperoxidase-labelled antibodies is reported for the ultrastructural localization of fixed immunoglobulins in tissue lesions. This technique allows the immunolabeling of frozen sections of 15 mu mounted on glass slides. These sections are then closed over for ultrastructural examination, using an Epon-filled gelatin capsule, and then returned to the glass slide. After polymerization, the capsule containing the tissue section is separated from the glass by immersion in liquid nitrogen. This technique is applied to the study of fixed Ig in the skin lesions of lupus erythematosus, pemphigus, bullous pemphigoid and dermatitis herpetiformis. The results obtained show a fine localization of fixed Ig, good tissue conservation and easy orientation of the biological material. It can be applied to the study of tissue antigens.

A comparative study of the sensitivities of the immunofluorescence (IF) and immunoperoxydase (IPo) techniques was undertaken. The material used was biopsies of various skin lesions and especially pemphigus, bullous pemphigoid, lupus erythematosus and dermatitis herpetiformis. Direct and indirect methods were performed for the detection of fixed immunoglobulins and complement deposits. With large deposits, immunoperoxydase and immunofluorescence show an equal sensibility and the labeling obtained with IPo is never more intensive than the labeling obtained with IF. In contrast, with small deposits, IPo was less sensitive than IF and appears negative in the majority of the cases and especially in dermatitis herpetiformis. These results are confirmed in using increasing dilutions of conjugates and can be explained by the difficulty in doing the observation of small positive deposits with IPo.

Occasional reports have appeared in the literature describing a relationship between pemphigus vulgaris and malignancy (Krain & Bierman, 1974; Tagami et al., 1976). Carcinoma of the ovary, stomach, breast, endometrium and bronchus have all been associated with pemphigus (Krain, 1974). The association between pemphigus and thymoma is well known (Stillmand & Baer, 1972). Pemphigus has also been described in connection with various lymphoproliferative malignancies (Naysmith & Hancock, 1976). The purpose of this paper is to describe a patient who suffered from a rare retroperitoneal tumour in association with pemphigus vulgaris. His serum contained a high titre of anti-skeletal muscle antibody, although he showed no clinical manifestations of myasthenia gravis. He also had immunological manifestations suggestive of lupus erythematosus.

The indirect immunofluorescence test has acquired great importance in the diagnosis of auto-immune skin diseases. Since it is sufficient only to send a sample of whole blood or blood serum to carry out the test, it is also of practical interest to the general practitioner. The test should be called upon if any of the following auto-immune skin diseases are suspected: pemphigus vulgaris (including p. vegetans, p. foliaceus, p. erythematosus), bullous pemphigoid (including benign mucosal pemphigoid) lupus erythematodes (systemic) and diffuse scleroderma.

The D-penicillamine (D-Pen.) treatment can induce some diseases accompanied by autoantibodies: lupus, pemphigus, myasthenia. The authors present the results of a systematic study of autoantibody occurrence during D-Pen.-treatment of the rheumatoid arthritis (RA): (1) Anti-nuclear antibodies are slightly positive in 34% of the untreated RA. They appear or enhance in 44% of the treated patients (22/50). They reach high titers (1/500) in two clinical-induced lupus and in three asymptomatic cases. (2) Anti-native DNA antibodies are not found in untreated patients. They become markedly enhanced in two clinical lupus as in three asymptomatic cases (3/50). (3) Anti-epidermal intercellular substance-antibodies are absent in non-treated as well as on pemphigus-free treated patients (0/40). They are slightly elevated in 5 induced pemphigus. (4) Anti-striated muscle antibodies are absent in non-treated patients, rarely and moderately elevated (3/40) in the asymptomatic D-Pen.-treated group. These findings could have a practical interest for the survey of the treatment.

Immunofluorescent studies are currently being done on patients with pemphigus, pemphigoid, dermatitis, lupus erythematosus and its variants, the cutaneous prophyrias, scarring alopecia, erosive mouth lesions, light-sensitive disorders, and cutaneous vasculitis. In this paper I shall review some of the recent advances in immunopathology and report the results that have been obtained in our laboratory.

The loss of intercellular and basement membrane antigens has been associated with the development of epidermal cell dysplasia and neoplasia. The antigenic components of the epidermis have been investigated in lichen planus, lupus erythematosus and eczema, using pemphigoid and pemphigus sera by the indirect immunofluorescent staining method. In areas of active lichen planus there was extensive reduction or complete absence of basement membrane antigen. Intercellular antigen was preserved in lichen planus although in some damaged rete ridges it appeared to be reduced. Both these antigens were well preserved in lupus erythematosus and eczema. Loss of epithelial antigens is therefore not confined to the development of neoplasia.
