    Abstract:
    AIM: To study content and clinical correlations of sTNF-RI in patients with systemic sclerosis (SS). MATERIAL AND METHODS: Thirty nine SS patients were examined with enzyme immunoassay for serum levels of sTNF-RI and soluble adhesion molecules (sSAM) sVSAM-1, sISAM-1 and sR-selectine using R&D System kits (USA). The control group consisted of 14 healthy subjects (donors). Content of sTNF-RI and sSAM was considered as elevated if it exceeded relevant mean values by 1SD. RESULTS: sTNF-RI content was significantly higher in the patients than in the controls (p = 0.0001) and was similar in patients with diffuse and limited forms of the disease. A rise in sTNF-RI correlated with a rise in pulmonary artery pressure. In patients with pulmonary hypertension or restrictive pulmonary affection sTNF-RI was higher than in patients free of pulmonary hypertension or impaired external respiration function. A marked correlation was found between sTNF-RI and sVSAM-1. Patients with high CRP had significantly higher sTNF-RI level than patients with normal CRP. CONCLUSION: SS is characterized by elevated content of sTNF-RI. This content may serve a diagnostic marker of the disease progression.
