Levels of soluble interleukin-2 receptor in the sera and skin tissue fluids of patients with vitiligo.

In order to study the possible role of soluble interleukin-2 receptor (sIL-2R) in the pathogenesis of vitiligo, we measured the levels of sIL-2R in the sera and the tissue fluids from skin lesions and uninvolved skin from 41 patients with vitiligo, using the method of sandwich ELISA with monoclonal and polyclonal antibodies. The results showed that the overall level of serum sIL-2R from patients with vitiligo was significantly higher than that from normal control group (P<0.01). The serum level of sIL-2R in both generalized and focal types was significantly higher than that in normal control group (P<0.01), but there was no significant difference between the segmental type and normal control group (P>0.05). The level of serum sIL-2R from patients with vitiligo in progressive stage was significantly higher than that in stable stage (P<0.01). The level of sIL-2R in the tissue fluid from the skin lesion of the patient was significantly higher than uninvolved skin of the same patient (P<0.05). The above data indicate that there is an association between the expression of sIL-2R and the pathogenesis of vitiligo. The level of serum sIL-2R in vitiligo is related to the activity of the disease, therefore the measurement of it may be significant in estimating the severity and the prognosis of the disease.

Clinical significance of serum levels of soluble interleukin-2 receptor in patients with localized scleroderma

Summary Localized scleroderma has been reported to be accompanied by abnormal immune reactions, including autoantibody production and lymphocyte activation. Lymphocyte activation can be quantitatively detected by measuring soluble interleukin-2 receptor (sIL-2R) in serum samples. In this study, serum sIL-2R levels were assayed by a sensitive enzyme-linked immunosorbent assay, in 48 patients with localized scleroderma, in 20 with systemic sclerosis (SSc) and in 20 healthy controls. Serum levels of sIL-2R were significantly higher in patients with localized scleroderma than in healthy controls. The serum levels of sIL-2R were correlated with the number of sclerotic lesions, the number of involved areas, the levels of anti-ssDNA, and the levels of antihistone antibody immunoglobulin M. Moreover, sIL-2R levels in sera from patients with SSc were also significantly higher than in healthy controls. Elevated serum levels of sIL-2R in localized scleroderma suggest that lymphocyte activation is one of the early processes in the development of this disease.     

Alopecia areata and interleukin-2 receptor.

Interleukin-2 (IL-2) is a lymphokine produced by activated T cells and its receptor (IL-2R) is expressed on T cells; one of the IL-2R components can be measured as a soluble serum protein (sIL-2R). Levels of sIL-2R were measured as a sign of T cell activation in serum of 12 patients suffering from alopecia areata (totalis or universalis) and in a group of healthy control subjects. An enzyme-linked immunosorbent assay was used to determine the levels of sIL-2R in blood samples drawn during both the active and resting phase of the disease. In patients with alopecia areata in active phase the sIL-2R concentrations were significantly higher than in stable phase and in controls. The biologic role of sIL-2R is still unknown, but one could speculate that T lymphocyte activation with subsequent secretion of IL-2 and IL-2R expression may contribute to the immune inflammatory mechanism of alopecia areata.     

Production of interleukin-2 by mononuclear cells in vitro in patients with atopic dermatitis and psoriasis. Comparison with serum interleukin-2 receptor levels.

Atopic dermatitis is associated with profound immunological alterations, in particular decreased lymphoproliferative responses upon stimulation with T-cell mitogens. T-cell blastogenesis involves the production of the soluble cytokine interleukin-2 (IL-2), which in turn upregulates the expression of its own receptor. To investigate the potential role of this cytokine for the pathomechanisms present in atopic dermatitis, 24-h supernatants of PHA-stimulated peripheral blood mononuclear cells from patients with atopic dermatitis (n = 30) of a moderate to severe disease activity were tested for IL-2 activity. In addition, serum concentrations of soluble interleukin-2 receptor (IL-2R) were measured. Non-atopic healthy controls (n = 19) and patients with psoriasis (n = 20), an inflammatory skin disorder with distinct pathogenesis, served as controls. In comparison with psoriasis patients and normal controls, PHA-stimulated mononuclear cells of atopic dermatitis patients released significantly less IL-2 into supernatants. Moreover, there was an inverse correlation between IL-2 concentrations and body surface involvement or serum IgE levels. In contrast, serum IL-2R levels were significantly elevated in both atopic dermatitis and psoriasis, as compared with healthy controls. Furthermore, IL-2R levels in atopic dermatitis patients showed a significant correlation with IgE levels and body surface involvement. The data indicate that T cell activation may occur in both skin diseases. Atopic dermatitis, however, is further characterized by the decreased capacity of mononuclear cells to release IL-2 upon stimulation in vitro.     

Serum concentration of the soluble interleukin-2 receptor in vitiligo patients

Serum levels of sIL-2R can be used to monitor in vivo immune activation and its elevation have been shown to be correlated with T cell mediated immune disease such as atopic dermatitis, psoriasis, lymphoma and systemic sclerosis. Vitiligo is the disease of depigmentation caused by destruction of melanocytes, and there have been extensive studies on the immune pathogenesis. If the pathogenesis of vitiligo is correlated with the activation of T lymphocytes, the change of IL-2R will be detected compared with that of normal control. Therefore we sought the change in sIL-2R to determine whether T lymphocytes from patients with vitiligo show abnormal biological behavior. The quantitation of sIL-2R was done by sandwich enzyme-linked immunosorbent assay (ELISA) from the sera of 79 vitiligo patients and 40 normal controls. The results were summarized as following. The sIL-2R level in vitiligo patients (671.91 +/- 368.59 U/ml) was significantly increased compared with that of controls (370.8 +/- 71.8 U/ml; P < 0.005). According to clinical types, sIL-2R level in focal type of vitiligo patients was significantly higher than those in other types (segmental or generalized; P < 0.05). The sIL-2R level in patients less than 1 year duration was significantly higher than in patients more than 1 year duration (P < 0.05). The sIL-2R levels were not significantly different between active and inactive group. There was no significant differences among sIL-2R levels according to sex or age of onset. Our study showed that sIL-2R level was higher in vitiligo patients compared with that of normal controls, so the activation of T lymphocytes would be an important component in the pathogenesis of vitiligo. The higher sIL-2R levels in recent onset group would suggest that sIL-2R level might be an acute immunologic marker in vitiligo patients.     

Soluble interleukin-2 receptor, CD4 and CD8 levels in melanoma: a longitudinal study.

Serum levels of soluble(s) interleukin-2 receptor (IL-2R), sCD4 and SCD8 were analysed in 227 melanoma patients, using a sandwich enzyme immunoassay. Different stages of the disease were considered, and a longitudinal study with a 2-year follow-up was performed. Mean values of sIL-2R were significantly higher than in normal controls in all stages and correlated with the disease progression. sCD8 increases with stage progression were less striking, while sCD4 values were always in the normal range. We conclude that sIL-2R measurement is a useful clinical parameter in monitoring disease evolution in melanoma.     

The Levels of Plasma Interleukin-2 and Soluble Interleukin-2R in Behçet's Disease: A Marker of Disease Activity

It is well known that patients with Behçet's disease (BD) have an activated immune system, probably mediated by soluble factors in the circulation. The purpose of our study was to examine the roles of plasma interleukin-2 (IL-2) and soluble interleukin-2 receptor (sIL-2R) in the pathogenesis of BD. Thirty-two patients with BD diagnosed according to the Criteria of the International Study Group for Behçet's Disease and 20 age-matched healthy persons were included in the study. The plasma levels of cytokines were measured by ELISA. Plasma levels of IL-2 and sIL-2R were increased in BD over controls, but the differences were not statistically significant. sIL-2R levels in patients with active disease were significantly higher than in either patients with inactive disease (p<0.001) or the control group (p<0.05). Our results suggest that the level of sIL-2R in BD seems to be related to disease activity.
