Rheosorbilact action on antitoxic function of the kidneys has been analysed using the values of medium weight molecules in patients with severe sepsis. The study design includes the criteria of inclusion, exclusion and cessation. Patients with pyoceptic complications (mainly surgical abdominal sepsis) with signs of severe endotoxicosis, dopaminergic activity (5-10 mcg/kg min), biochemical criteria of SS (lactate >4 mmole/l, С-reactive protein >2 standard departures from the norm) and other signs of severe sepsis with generalized disorders in homeostasis (assessing the multiple organ damage course by H.Celye-I.A. Yeriuhin scale- 20-27 points, MODS scale – 6-10 points) corresponded to the inclusion criterion. All patients were provided with appropriate debridement and intensive traditional therapy. For control studies we involved patients with systemic inflammatory response syndrome who had 2-3 signs of SIRS in stage A. It was found that rheosorbilact activates the transportation of medium weight molecules out of the extracellular space and increases their excretion by the renal nephrons in patients with severe sepsis. It was established that in severe sepsis rheosorbilact provides a high level of excretion of medium weight molecules by suppressing processes of reabsorption in the proximal nephron portions caused by peptidase dependent metabolism.
