The authors studied comparatively a number of indices of nonspecific immune protection in 32 patients with paraneoplasia, in 34 patients with malignant (19) and benign (15) skin neoplasms, and also in 20 healthy persons. It has been found that in patients with paraneoplasias and skin cancer the most sensitive tests for decreased immune responses are as follows: qualitative and quantitative changes in the autoflora of non-involved skin covers, lysozyme titre and general bactericidity of blood serum. A progressive increase of dissemination of the skin cover against the background of the reduced lysozyme titre and general bactericidity of blood serum and also the appearance of C-reactive protein in serum render it reasonable to suspect malignant tumor process in patients suffering eczema, psoriasis and other skin lesions.

In vitro degranulation of polymorphonuclear leukocytes, which were stimulated either with synthetic chemotactic peptide (N-formyl-methionyl-leucyl-phenylalanine, FMLP) or with C3b-opsonized zymosan as a promotor of phagocytosis, was studied in 66 patients with psoriasis, 18 lesion-free psoriatics, 18 healthy subjects, and 14 other dermatological disorder controls. Stimulated release of lysozyme (from specific granules and azurophil granules) and beta-glucuronidase (from azurophil granules) in the presence of both FMLP and serum-activated zymosan was markedly reduced in patients with actively spreading guttate psoriatic lesions, in whom relapse of lesions lasted for less than 1 month and papules involved about 13-25% of skin surface. In contrast, stimulated degranulation was within normal range in active plaque psoriasis, stationary plaque psoriasis, symptomless psoriatics, and patients with disseminated eczema. Spontaneous release of lysozyme and beta-glucuronidase (background) was found to be not different in all groups studied; however, patients with active guttate psoriasis had significantly lower total lysozyme activity than those with active and stationary plaque psoriasis as well as psoriatics in the remission. These data are in favor of in vivo activation of neutrophils in active guttate psoriasis by some factors related to the early relapse of the lesions. This results in a possible combination of the following phenomena: (1) in vivo partial degranulation of neutrophils; (2) induction of "unresponsiveness state" of these cells to subsequent in vitro stimulation; and/or (3) migration of highly responsive neutrophils to skin lesions, which leaves in the circulation the subpopulation less reactive to chemotactic and phagocytic stimuli.

The objective was to compare impact of indoor office environment on employees with eczema with those without eczema. Exposure was measured at 56 sites and modelled for 173 work places. Tear film stability, lysozyme in nasal lavage, immunoglobulin E (IgE), and Phadiatop were assessed, and symptoms and perceptions collected by questionnaires. Multiple regression analyses were applied, adjusted for age, gender, strain, current smoking, and respiratory infections. Those with eczema perceived temperature too high but not associated with measured temperature. They had increased lysozyme in nasal lavage associated with increased air temperature difference between 6 and 10 AM, more general and mucosal symptoms, and "dry or flushed facial skin" associated with airborne particulate matter less than 10 microns in diameter (PM(10)). Impact of PM(10) was most pronounced among those with eczema previous 30 days. Having eczema might be an important predictor for subjective and objective responses to indoor environment.
