title: Inflammatory Syndromes (SIRS, MARS, CARS) in Patients with Surgical Infection.
abstract: In the present study 37 patients with surgical infection were investigated and a new set of diagnostic tests for detection of major syndromes of systemic inflammation - systemic inflammatory response syndrome (SIRS), compensatory anti-inflammatory response syndrome (CARS) and mixed antagonist response syndrome (MARS) - was developed. In summary, we have demonstrated that patients with surgical infection were characterized by an immunodeficiency with significant reduction of mitogen-induced proliferation and IL-2/IL-4 production in vitro combined with decrease of HLA DR(+) monocytes. Furthermore, it was revealed that the patient's serum exhibited substantially enhanced suppressive and inflammatory activities as well as the level of C-reactive protein. We have defined the negative correlation between the serum inflammatory and suppressive activities (SIA and SSA) that was most prominent at the early stage of disease. Since the changes of serum bioactivity in the course of surgical infection were prominent and coherent, we supposed that tested activities might reflect the distinctive features of systemic inflammation. In according to this assumption, the patients were divided into 3 subgroups with predominance of SIRS, CARS and MARS by using the SIA and SSA expression. It has been shown that SIRS was more frequently detected at the early stage, whereas CARS - at the late stage of disease. Patients with SIRS, CARS or MARS significantly differed by the content of CD8(+) T and CD72(+) B lymphocytes, the concentration of IgG and IgA, the production of IL-2 and IL-4. Finally, the data obtained from patients, those were studied repeatedly, showed the possibility of transformation of the major systemic inflammatory syndromes during the disease course. Our findings suggest that measurement of serum inflammatory and suppressive activities may help to differentiate patients with SIRS, CARS or MARS and to select the appropriate strategy of immunotherapy.
