[Some clinical symptoms and allergens on asthma-prurigo syndrome].

The group of 146 patients suffering from asthma-prurigo syndrome (85 adults and 64 children) have been inquired in many various clinical centers. It was established that in 79.6% of the patients the first symptoms of illness appeared already in infancy and only 28.2% of the patients had negative familiar anamnesis on the allergy. In 73.2% of the patients with asthma-prurigo syndrome the symptoms of atopic dermatitis persisted longer than asthma symptoms and in 89.9% of them asthma-prurigo symptoms accompanied other form of allergic diseases. The most important causal allergens provoking asthma-prurigo symptoms were: house dust (in 64.4% of the patients), chocolate (in 42.2%), cat epithelia (in 40.2%) and cow milk proteins (in 29.5% of the patients).

[Changeability of respiratory tract and skin symptoms in patients with asthma-prurigo syndrome under the influence of emotional and environmental factors].

In a group of 228 patients suffering from asthma-prurigo syndrome the influence of emotional state, permanent residence and season time on dynamic of the clinical symptoms were studied. The evaluation of emotional state in 80 adult patients was carried-out by means of Eysenck Personality Inventory. The emotional state had less negative influence on the exacerbation of the symptoms upon children then in adults (especially on their skin symptoms). It was confirmed that the patients with high level of neurotic symptoms revealed easier the exacerbation of asthma and skin disorders under the influence of emotional stress. The climatic treatment on the sea-side was more efficient for them than any mountain climatic cure, especially in the treatment of airways symptoms. Similarly, the summer season brought the relief of their symptoms from both the respiratory and skin symptoms.

Frequency and significance of the major and minor features of Hanifin and Rajka among patients with atopic dermatitis.

In 481 patients with atopic dermatitis (AD), 4 major features of Hanifin and Rajka were found in 72%, and in 96% over 6 minor features were seen, which is much more than the minimum required by these authors for making a 'firm diagnosis'. The incidence of particular minor features in all patients was varying significantly, and in subgroups of patients they appeared with different frequency. For example, asthma occurred more often in AD patients with the onset of skin lesions before the 6th month of life, and food intolerance was more frequently observed in patients with very high serum IgE level. In the control groups some minor features also occur but less frequently than in AD patients. We conclude that the anterior neck folds and Dennie-Morgan infraorbital fold should be regarded as minor AD features.

Acitretin decreases tumor cell-induced angiogenesis.

The effects of acitretin and etretinate on angiogenesis induced in Balb/c mice by intradermal injection of keratinocyte tumor cell lines were evaluated. It was shown that both retinoids are capable of inhibiting angiogenesis evoked by a human epidermoid carcinoma cell line (A431). Acitretin, but not etretinate, inhibited also angiogenesis induced by the spontaneously transformed murine keratinocyte cell line Pam 212 and by the established tumorigenic SKv cell line harboring the HPV16 genome. We suggest that inhibition of blood vessel formation may be one of the mechanisms responsible for the anticancerogenic effect of retinoids.

Lymphocyte-induced angiogenesis assay--in cutaneous malignancies and cutaneous and genital warts.

Lymphocyte-induced angiogenesis assay (LIA) was used to evaluate immunocompetence of lymphocytes obtained from patients with basal cell carcinoma, squamous cell carcinoma, genital viral warts and from renal allograft patients under immunosuppressive therapy with multiple cutaneous warts. LIA revealed no abnormalities of angiogeneic capabilities of lymphocytes, except these from immunosuppressed patients which evoked significantly lower angiogeneic reaction than lymphocytes from healthy controls.

Increased natural killer cell activity in patients with epidermodysplasia verruciformis.

Six patients with epidermodysplasia verruciformis (EV) were studied for natural killer cell (NKC) cytotoxic response of their peripheral blood mononuclear cells against K-562 target cells in an 18-hour chromium 51-release assay. Four patients displayed higher cytotoxic responses than controls did, whereas two others did not differ from controls. Patients with EV who had increased NKC activity were found to be infected with potentially oncogenic human papillomaviruses (types 5, 8, 9, 14, 17, 19, 22, 24, and others), and they have had multiple skin carcinomas and/or Bowen's precancerous dermatosis. Two patients with EV who had normal cytotoxic response were free of skin malignancies.

The adherence to human endothelium and plastic of neutrophils from psoriatic patients, and the effects of psoriatic patients' sera on normal neutrophils.

Circulating polymorphonuclear neutrophils (PMNs) from 50 patients with psoriasis vulgaris and from 38 control individuals (28 healthy blood donors and 10 patients with systemic sclerosis) were tested for their ability to adhere to human endothelial cell monolayer and a plastic surface. We also studied the effect of sera from psoriatic patients on the adherence and chemotactic activity of normal human neutrophils. The neutrophils from patients with psoriasis were much more adherent to the endothelium and the plastic surface, and this correlated positively with the activity of the disease, but inversely with the extent of the skin lesion. The sera from patients with active psoriasis were found to enhance the adherence and chemotaxis of normal human PMNs. Treatment of the sera by heat (56 degrees C for 30 min) did not affect their enhancing effect on the adherence but significantly decreased their effect on the chemotactic activity of normal PMNs.

Angiogenic capability of peripheral blood mononuclear cells in psoriasis.

The angiogenic capability of peripheral blood mononuclear cells (MNCs) from patients with psoriasis was tested by lymphocyte-induced angiogenesis assay. The study was performed in 36 patients with psoriasis vulgaris, six with generalized pustular psoriasis of the von Zumbusch type, and five with palmo-plantar pustular psoriasis. When patients with psoriasis vulgaris were considered as a whole, no significant differences in the angiogenic capability of their MNCs could be detected, as compared with controls. However, when cases of psoriasis were classified into various types, the differences in angiogenic capability of MNCs became evident. This capability was found to be markedly increased in the active form of psoriasis vulgaris and decreased in the stationary stage of the disease. It was increased in palmo-plantar pustular psoriasis but markedly decreased in generalized pustular psoriasis of the von Zumbusch type.

Inhibition of tumour-induced angiogenesis by systemically administered protamine sulphate.

Systemic administration of protamine sulphate significantly decreased the intensity of angiogenesis induced in X-ray immunosuppressed (BALB/c X DBA/2W) F1 mice by either HEp-2 (human larynx carcinoma) cells or semi-syngeneic splenocytes injected intradermally. In vitro experiments have shown that protamine sulphate markedly decreases the proliferation of human endothelial cells as assessed by 3H-TdR incorporation assay. In contrast, the proliferation of HEp-2 cells was not affected, and only slight inhibition of normal human fibroblasts could be demonstrated. Heparin abolished the inhibitory effect of protamine sulphate, both in vivo and in vitro. These results suggest that the observed inhibitory effect of protamine sulphate on angiogenesis in vivo may be at least partially due to the interaction of this compound with endothelial cells.

Protease-mediated enhancement of lymphocyte-induced angiogenesis in X-ray irradiated mice.

Angiogenesis was induced in mice by intradermal injection of semi-syngeneic splenocytes, and after three days the number of newly formed blood vessels at the injection site was counted. When recipients were total-body irradiated with 700 R 2 hours before the lymphocyte injection, the angiogenesis was significantly higher than in non-irradiated mice. The angiogenesis enhancement was of a systemic (not local) character as revealed in experiments with shielding of irradiated animals. This enhancement was not due to X-ray dependent immunosuppression, as shown in experiments with non-irradiated, pharmacologically immunosuppressed mice. Decreased angiogenesis was observed in irradiated mice after treatment with cortisone acetate, aprotinin, and EACA. The results suggest that proteases might be involved in mediating the angiogenesis enhancement after X-irradiation.

Heterotopic transplantation of syngeneic lymphoid tissues in mice. The ability of graft repopulation cells to enhance cell-mediated immunity as measured in the lymphocyte-induced angiogenesis assay.

Fragments of murine spleen and Peyer's patches were transplanted under the kidney capsule of syngeneic recipients. The ability of graft-repopulating cells to enhance cell-mediated immunity was tested in a lymphocyte-induced angiogenesis assay. The ability to evoke angiogenesis expressed by cells isolated from 10-day-old grafts of both tissues was significantly lower than that of cells isolated from organs in situ and was restored to control levels in both types of grafts 30 days after transplantation. Cells of Peyer's patch grafts showed weaker ability to induce angiogenesis than cells of spleen grafts regardless of the graft's age. Cells isolated from Peyer's patches in situ also showed weaker angiogenesis-inducing ability compared with normal spleen cells. Hence the results suggest that the repopulation of lymphoid tissue graft is specifically influenced by the graft's microenvironment.

Enhancing effect of X-ray irradiation on a new blood vessel formation in mice tested by lymphocyte induced angiogenesis assay.

X-irradiation enhanced a new blood vessel formation occurring in the course of a local GvH reaction in mice. Maximal enhancing effect was exerted by single total body irradiation doses ranging from 700 to 1050 R. Fractionation in daily doses smaller than 200 R did not exhibit enhancing effect. Proliferative ability of angiogenesis inducing cells is not necessary for enhancing effect of irradiation.

[Local use of leukotriene inhibitor--NDGA in psoriasis].

NDGA is known as an inhibitor of leukotrienes and may exert some effect on psoriatic lesion formation. The aim of the study was to test the influence of this drug on appearance of psoriatic plaques. 7 day application of 0.015% NDGA on psoriatic lesions under occlusion in 23 patients, gave some flattening of lesions as compared to controls. However, after finishing of application all the changes reappeared in previous form. We have never observed permanent beneficial effect in any patient.
