Linear IgA bullous dermatosis. An immunologically defined disease.

Linear IgA bullous dermatosis (LABD) can mimic bullous pemphigoid (BP) and/or dermatitis herpetiformis (DH) both clinically and histologically. LABD, however, can be distinguished from BP and DH by direct immunofluorescent (IF) demonstration of linear IgA deposits along the basement membrane zone. A retrospective study of 234 cases of BP, 27 cases of LABD, 60 cases of DH, and 20 cases of cicatricial pemphigoid (CP) revealed that BP patients are significantly older than LABD or DH patients and LABD patients are significantly older than DH patients. BP and CP occur more frequently in women (65-70%) than LABD or DH (44-48%). The frequencies of C3 deposits in the basement membrane zone (BMZ) are significantly higher in BP (85%) compared with LABD (18.5%) and DH (28.3%). LABD patients varied in their response to various therapeutic agents. Some responded to corticosteroids and some to sulfones alone, whereas others required a combination of corticosteroids and sulfones.

In vitro effects of enzymes of polymorphonuclear leukocytes on the antigenicity of stratum corneum.

Anti-stratum corneum (SC) antibodies of human serum bind in vitro to the SC of frozen sections of normal skin of psoriatic patients and of healthy controls. Pretreatment of skin sections with selected dilutions of acid extracts from polymorphonuclear leukocytes (PMN) prior to the incubation with serum containing anti-SC autoantibodies enhances this binding in comparison with binding to untreated sections. Pretreatment of at least some specimens with higher concentrations of the same PMN extracts brings about a reduction in their reactivity with anti-SC autoantibodies. These findings indicate that enzymes of PMN are capable of altering SC antigens by first increasing and then decreasing their reactivity with SC autoantibodies.

13-cis-Retinoic acid and tetracycline versus 13-cis-retinoic acid alone in the treatment of nodulocystic acne.

A comparative clinical study on therapy of nodulocystic acne with 13-cis-retinoic acid was performed in 32 patients. 20 patients were treated with a dose of 1 mg/kg body weight daily, and 12 with a combined therapy: 0.25 mg/kg/day 13-cis-retinoic acid and 0.5 g of tetracycline daily. In both groups the therapy was carried out for 16 weeks. The effect of the combined therapy within 4 months was favourable in 75% of the cases versus 100% in the group treated with larger doses of 13-cis-retinoic acid. Thus, the time needed for clearing was longer in some patients (up to 6 months). However, the incidence of side effects was considerably lower in the group of combined therapy. In acne fulminans 13-cis-retinoic acid alone is not effective and should be combined with corticosteroids.

[Peritoneal dialysis and leukopheresis in psoriasis: indications and contraindications].

Twenty-four patients with severe psoriasis were treated with continuous peritoneal dialysis and ten patients with repeated leukopheresis, with comparable clinical results: about 20%-30% of the patients had complete remission of the lesions during the therapy, about 40% showed spontaneous regression of above 50% of psoriatic lesions, and the remaining patients had some improvement. However, despite partial improvement during treatment, the psoriatic lesions of the patients that were previously unresponsive to any external and internal treatment disappeared within 2-3 weeks, after discontinuation of dialysis or leukopheresis, with the use of anthralin or tar ointments. Peritoneal dialysis and leukopheresis seem to be useful methods of treatment for especially resistent and widespread psoriasis in patients having contraindications to other methods, i.e., PUVA and/or aromatic retinoids.

[Fasciitis eosinophilica--transition to an unusual scleroderma (scleroderma-fasciitis)].

Eosionophilic fasciitis (EF) was observed in a girl who suddenly developed indurations of the limbs accompanied by hypergammaglobulinaemia and peripheral eosinophilia. The deep fascia was impressively thickened and infiltrated with numerous inflammatory cells showing focal accumulations of eosinophils. The disease was progressive in spite of application of corticosteroids, and within three years, symmetrical sclerodermatous lesions developed on the face and trunk, going along with a severe sclerodactyly without Raynaud's phenomenon, as well as contractures of the upper and lower limbs causing complete disability. Visceral involvement was slight (decreased motility of the esophagus and restriction of pulmonal function); slight calcium deposits were disclosed at the soft tissue of the ankles; and nuclear antibodies of the speckled type appeared in a titer up to 320. The fascia was still the most involved tissue, but there was no peripheral or tissue eosinophilia. EF seems to be a special variant within the broad spectrum of scleroderma; and although it usually has a benign course, it may change into an unclassified variety of scleroderma and lead to severe disability.

Lowered angiogeneic capability of peripheral blood lymphocytes in progressive systemic sclerosis (scleroderma).

Peripheral blood lymphocytes isolated from 19 patients with progressive systemic sclerosis (7 with diffuse scleroderma and 12 with CREST syndrome) and from 19 healthy control individuals were tested in a lymphocyte-induced angiogenesis assay. The cells were injected intradermally into x-ray-immunosuppressed mice and their capability to induce new blood vessel formation was assessed by morphologic criteria. The lymphocytes derived from patients with systemic scleroderma showed a significant decrease in angiogeneic capability compared with controls. No significant difference in this capability was found between patients with diffuse scleroderma and those with CREST syndrome. The decrease in the angiogeneic capability of lymphocytes reflects a depression in cell-mediated immunity and might be relevant to the capillary loss observed in systemic scleroderma.

IgA anti-endomysium antibody. A new immunological marker of dermatitis herpetiformis and coeliac disease.

The recently described IgA anti-endomysial antibodies (IgA-EmA) are directed against the intermyofibril substance of the smooth muscle, which may correspond either to a reticulin-like structure or a surface component of smooth muscle fibrils. These antibodies occurred in about 80% of sera of thirty-eight patients with dermatitis herpetiformis (DH), in about 70% of twenty-eight patients with coeliac disease and in about 20% of nine patients with other enteropathies. IgG class anti-gliadin antibodies (AGA) also occur in each of these diseases. Both antibodies were detected on monkey oesophagus by immunofluorescence. The IgA-EmA could not be detected in 122 control sera from patients with other gut or skin diseases, including fifteen cases with ulcerative colitis and fifteen cases with linear IgA bullous dermatosis (LABD). The presence and the titre of IgA-EmA and AGA paralleled the severity of the jejunal changes in patients with coeliac disease.

Congenital fascial dystrophy--a noninflammatory disease of fascia: the stiff skin syndrome.

Our patient's disease was similar to the persons with stiff skin syndrome described by Esterly and McKusick (1). Stony-hard indurations of the skin and deeper tissue were generalized but most pronounced in the buttocks, thighs, and legs, with limitation of joint mobility and particularly extensive contractures in the lower limbs. The disease was noticed when the patient was 18 months old, and was nonprogressive within a follow-up period of 12 years. There was no visceral involvement except functional impairment of the lungs, probably due to thickened thoracic fascia. Biochemical, histologic, and electron microscopic studies of the skin and muscle were not remarkable. In skin fibroblasts, collagen synthesis was increased and was accompanied by elevated activity of the prolylhydroxylase and lysylhydroxylase, whereas the transferases were not altered. The fascia was considerably thickened, but contained no inflammatory infiltrates. The significant electron microscopic finding was the presence of amianthoid-like collagen fibers in the fascia.

Molecular cloning and characterization of the genomes of nine newly recognized human papillomavirus types associated with epidermodysplasia verruciformis.

The genomes of 11 human papillomaviruses (HPVs) found in benign lesions of eight patients suffering from epidermodysplasia verruciformis were cloned in Escherichia coli after insertion into plasmid pBR322. The study of the sensitivity of the cloned HPV DNAs to 14 restriction endonucleases permitted the construction of physical maps. DNA-DNA hybridization experiments, performed under stringent conditions, showed that these viruses represent nine new types, HPVs 14 (with subtypes a and b), 15, 17 (with subtypes a and b), 19, 20, 21, 22, 23, and 24. These HPVs were divided into three groups based on an absent or very weak cross-hybridization among the genomes of the viruses belonging to different groups.

Circulating immune complexes in systemic scleroderma.

Circulating immune complexes were detected by the immunoelectrophoretic method in 18 of 29 (62 per cent) of patients with systemic scleroderma. The presence of immune complexes did not correlate with that of antinuclear antibodies to dsDNA, DNP, RNP, and Sm. The mean levels of immunoglobulins G, A, and M as well as of C3 were significantly higher in patients with systemic scleroderma than in blood donors.

Capillary microscopy in eosinophilic fasciitis. A comparison with systemic sclerosis.

Capillary microscopy was performed on 19 patients with eosinophilic fasciitis. These patients were compared with 13 individuals with progressive systemic sclerosis (scleroderma). Capillary patterns were normal in 16 of 19 (84%) eosinophilic fasciitis patients; 3 exhibited either borderline or nonspecific changes, and none showed a definite scleroderma pattern. In contrast, characteristic nailfold capillary changes, consisting of both dilatation and loss of capillaries, were present in 11 of 13 (85%) scleroderma patients; the remaining 2 showed scleroderma-type abnormalities of only 1 finger and were, therefore, classified as borderline. These results suggest that capillary microscopy may help to distinguish these 2 disorders.
