Acquired subepidermal bullous diseases associated with psoriasis: a clinical, immunopathological and immunogenetic study.

Clinical, immunopathological and immunogenetic studies of four patients with a subepidermal bullous disease associated with psoriasis were carried out to determine the true nature of the blistering disease and to investigate further the relationship between psoriasis and acquired subepidermal bullous diseases. Autoantibodies in all four patients bound to the epidermal side of salt-split skin by indirect immunofluorescence and detected the major bullous pemphigoid (BP) antigens by immunoblotting. One had additional IgA autoantibodies binding an epidermal polypeptide of 270/280 kDa and another had circulating IgG autoantibodies which detected both BP and epidermolysis bullosa acquisita (EBA) antigens. All patients had active psoriasis at the onset of the bullous disease. Three patients were being treated with tar when blisters developed; one patient also received UVB radiation and experienced a relapse after exposure to sunlight. HLA phenotypes in three patients were determined. All the patients responded well to methotrexate. These findings demonstrate that BP is the subepidermal bullous disease most associated with psoriasis. Changes at the basement membrane zone in psoriasis may be responsible for the heterogeneous antibody response and may trigger the bullous disease, as may antipsoriatic treatment including tar and UV radiation. However, common immunogenetic mechanisms may play a crucial part in this disease association.

Semen contact urticaria.

An allergic reaction to human seminal fluid was first reported by Halpern et al. 1967. Since then there have been more than 30 cases recorded in the literature but it remains a rare cause of dyspareunia.

Chronic bullous dermatosis of childhood--clinical and immunological features seen in African patients.

During the period 1985-88, 30 children with a chronic blistering dermatosis were studied. Of these 25 were found to have chronic bullous dermatosis of childhood (CBDC) and five had bullous pemphigoid (BP). No case of dermatitis herpetiformis (DH) was seen in the same period. Except for the difference in immunofluorescence (IMF) there were no definite clinical, histological or therapeutic differences between the two groups. All the children were Africans with the exception of one Indian girl. Their ages ranged from 1 year to 12 years with a mean of 5 years. The females outnumbered the males in a ratio of 3:2. All children had a generalized eruption consisting of large tense blisters arising on normal skin. The blisters were more profuse on the lower trunk, pelvic region and limbs. Face and scalp were also affected. Histological features of BP and DH were seen. Direct IMF in the CBDC patients showed linear deposits of IgA at the basement membrane zone (BMZ) while linear deposits of IgG were seen in the BP group. Complement and IgM were also seen in some cases in both groups. Sixty per cent of the CBDC patients showed IgA BMZ antibodies by indirect IMF. There were no symptoms or signs of malabsorption. Serum vitamin B12 and folate levels were normal. HLA studies showed the B-8 antigen in five of the 20 patients studied. Therapy was difficult in most cases. All patients haemolysed on therapeutic doses of dapsone, sulphapyridine and/or prednisone had to be added. Follow-up was generally poor as six patients failed to return after discharge from hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

Autoimmune progesterone dermatitis responding to Tamoxifen.

A case of autoimmune progesterone dermatitis is described. Exacerbation occurred premenstrually and after intramuscular and oral challenge with synthetic progesterone. The condition failed to respond to oestrogen, but there has been a marked improvement with the anti-oestrogen drug Tamoxifen.

Anti-androgen treatment in women with acne: a controlled trial.

Ninety female patients with acne were allocated randomly to one of three groups and treated either with Diane, a high dose cyproterone acetate (CPA) regime with ethinyloestradiol, or Minovlar. The same dose of oestrogen was common to all three treatment groups. Patients were assessed every 2 months for 6 months, by grading for severity of the acne, lesion counts and photography, and subjectively using a visual analogue scale. In addition, bacteriological sampling and sebum excretion rate (SER) measurements were performed. The results showed a clinical improvement in all three treatment groups, but a more rapid and complete response was seen in those groups who received CPA. There was also a consistent trend suggesting a more favourable response in those in the high dose CPA group. Although there was a marked reduction in SER in the groups treated with CPA, there was no correlation between reduction in SER and clinical improvement in individuals, nor could a reduction in the surface bacterial population be shown to be a primary event in the success of anti-androgen therapy. We have shown that the addition of CPA to oestrogen adds significantly to the therapeutic effect in acne and that anti-androgen and oestrogen combinations are more effective than standard oestrogen and progestagen contraceptive pills.
