ABSTRACT

UNLABELLED: Chemokines promote leukocyte traffic into the site of inflammation. It depends on the repertoire of chemokines synthesized locally, and the temporal expression of chemokine receptors on leukocytes among them lymphocytes B and T which play crucial role in the pathogenesis of autoimmune diseases for example in systemic lupus erythematosus (SLE). RANTES (regulated upon activation in normal T cells expressed and secreted) is chemokine influencing T cells and BLC 1 (B-lymphocyte chemoattractant 1) is chemokine which affects B cells. The aim of the study was to evaluate serum concentration of the above mentioned chemokines in treated SLE patients and to analyze the relationships between their concentration in patients group and the control one. Another aim of our study was to assess the relationships between serum levels of these chemokines and the total peripheral blood leukocyte count and between serum levels of these chemokines and absolute peripheral blood counts of the individual forms of these cells in SLE patients. MATERIAL AND METHODS: Serum levels of RANTES and BLC 1 were determined in 48 treated women with SLE and mild-to-moderate disease severity. The results were compared between the total SLE group and the control (29 healthy women). The correlation between chemokines and between their levels and peripheral blood leukocyte count were evaluated. The relationships between the analyzed chemokines were also determined in the control group. RESULTS: Lower level of RANTES in serum was revealed in patients with SLE compared to the control and the tendency to higher concentration of BLC 1 in serum was observed. No relationships were observed between the levels of these chemokines both in the SLE patients and in the control group. Whereas the negative correlations between BLC 1 and total leukocyte count and BLC 1 and absolute number of neutrophils were found without such correlation between BLC 1 the subgroup of patients with concomitant neutropenia. CONCLUSION: We suggest that in treated patients with SLE lowered level of RANTES and tendency to higher level of BLC 1 is observed which have not any connections with the peripheral blood leukocyte counts and individual forms of these cells counts.

ABSTRACT

UNLABELLED: The relationships between different autoimmune diseases and among them the connections between systemic lupus erythematosus (SLE) and autoimmune thyroid diseases have been reported for a few years. The aim of this study is the assessment of the laboratory tests findings which are applied in the evaluation of the thyroid function and prolactin (PRL) concentration in serum in women with SLE during therapy. MATERIAL AND METHODS: In 41 women with SLE treated in the period of a few months to several years the following laboratory tests were performed: the concentration of thyroid stimulating hormone (TSH), PRL and free triiodothyronine (fT3) and free thyroxine (fT4) levels were measured by chemiluminescence technique, anithyroid antibodies (anti-thyroperoxidase - anti-TPO, and anti-thyroglobulin - anti TG) were tested by immunofluorescence assay. The control group consisted of 17 healthy women of a similar age to the SLE patients. RESULTS: The levels of fT3 and fT4 were statistically significantly lower in SLE patients comparing to the controls but the arithmetic means for the whole investigated patients were within the range of laboratory limits for these hormones. Considering other parameters no statistical differences between the mean values were observed. CONCLUSIONS: The results indicate that fT3 and fT4 concentrations are lower in SLE treated women with small and mild disease activity compared to the controls with the mean arithmetic values for the total group of patients which is within the laboratory limits for these hormones. Furthermore, the results seem to support the tendency of connections between the detection of antithyroid antibodies with higher level of serum PRL in SLE treated patients.
