Thymopentin treatment of herpes simplex infections. An open, monitored, multicenter study.

Twenty-seven patients suffering from long-standing, severe, recurrent herpes simplex (14 labial and 13 genital) who had not responded adequately to prior therapy were recruited for this open, monitored study. They were treated with thymopentin 50 mg subcutaneously three times weekly for a period of 6 weeks. Clinical controls were performed once a week and then again 6 weeks after cessation of therapy; laboratory investigations were done at time points 0, 3, and 6 weeks. Additionally, information was collected with regard to the clinical course during the following year. Thirteen of 14 patients with labial infection and 10 of the 13 with genital herpes improved markedly (p less than 0.05) as shown by decrease in the relapse rate of at least 50%, shorter relapse episodes, and improvement of symptoms such as pain and itching. Fourteen of these 27 patients experienced no relapse for a period longer than 4 months after cessation of therapy. These favorable results were paralleled by a statistically significant increase in the T cell helper/suppressor ratio. This finding indicates that thymopentin acts as an immunodomulator; it is assumed that the activation of T helper cells induces-presumable via interleukin 2-the proliferation of cytotoxic T lymphocytes and natural killer cells which play a major role in the natural immune defense. No serious side effects of thymopentin were recorded.

The effect of thymopentin treatment on the relapse rate in frequently relapsing herpes simplex virus infections.

Twenty-four patients suffering from longstanding severe recurrent herpes simplex, who had not responded to prior therapy, were treated with s.c. thymopentin injections 50 mg, three times weekly, over a period of six weeks. They were followed up at weekly intervals over this period and then six weeks later. Moreover, the longest relapse-free period observed in the year after the treatment was recorded in the investigator's documentation. Thirteen of the 14 patients with labial herpes simplex and 10 of the 13 patients with genital herpes simplex improved markedly as shown by a decrease in the relapse rate of at least 50%, shorter episodes of relapse and improvement of symptoms such as pain and itching. Fourteen of these 27 patients experienced no relapse for a period longer than four months after cessation of the therapy. No serious side-effects were observed. Laboratory examinations before, during and after thymopentin did not reveal significant alterations except for an increase in the T-helper/T-suppressor ratio. The effect of thymopentin is assumed to be due to T-helper cell activation resulting in enhanced interleukin-2 production with subsequent proliferation of cytotoxic T lymphocytes and natural killer cells which are capable of producing immune interferon.

Clinico-immunologic correlations in pemphigus and bullous pemphigoid.

Specific immunopathologic data can be found in 95% of patients with pemphigus vulgaris and in 70% of patients with bullous pemphigoid. Antibodies in pemphigus vulgaris can belong to different classes of immunoglobulins and can be destroyed by immunosuppression. Twenty percent of the pemphigus patients had differing results suggesting early recurrence of disease. In patients with bullous pemphigoid, there is great variability in anti-basal zone antibodies. When the disease clears, there is still a wide range of immunologic patterns.

The biosynthesis of prostaglandins in psoriatic skin.

The biosynthesis of prostaglandins (PGs) was studied in biopsy material taken from 8 psoriatics and 7 healthy controls. The psoriatic skin showed a statistically significant reduction in the capacity for PG synthesis: in psoriatic skin PGE2 was 301 +/- 74 ng/g wet weight and PGF2 alpha 425 +/- 89 ng/g wet weight, whereas in healthy skin the synthesizing capacity of PGE2 was 507 +/- 45 ng/g wet weight and of PGF2 alpha 730 +/- 206 ng/g wet weight.

Alantolactone sensitivity in chrysanthemum contact dermatitis.

A case of occupational chrysanthemum contact dermatitis is reported. Patch tests showed the patient to be sensitized to Chrysanthemum morifolium (Chr M) leaves, flowers, and stems (alcoholic extracts) and to alantolactone. An attempt at desensitization appears to have been successful. Gas chromatography indicated the presence of alantolactone in all the various parts of Chr M, mostly in the flowers. The "maximization test" succeeded in sensitizing guinea pigs to alantolactone.

Ultrastructural findings in bullous pemphigoid.

In four bullous pemphigoid patients electron microscopic and direct immunofluorescence examinations were carried out on sections of the border of a blister, apparently normal skin surrounding the blister, apparently normal skin distant from the blister, and apparently normal skin subjected to the stimulus of a xenon lamp. The bullous pemphigoid blister was formed by cleavage of the basal cells away from the basal lamina which remained intact. The intercellular spaces were widened and the half-desmosomes reduced in number in the skin surrounding the blister. Xenon lamp irradiation produced a pattern similar to that of the skin surrounding the blister, but without immunoglobulins and complement fixed in vivo.
