Systemic inflammatory response syndrome (SIRS) is a common clinical condition in patients in intensive care units that can lead to complications, including multiple organ dysfunction syndrome (MODS). MODS carries a high mortality rate, and it is unclear why some patients resolve SIRS, whereas others develop MODS. Although oxidant stress has been implicated in the development of MODS, several recent studies have demonstrated a requirement for NADPH oxidase 2 (NOX2)-derived oxidants in limiting inflammation. We recently demonstrated that NOX2 protects against lung injury and mortality in a murine model of SIRS. In the present study, we investigated the role of NOX2-derived oxidants in the progression from SIRS to MODS. Using a murine model of sterile systemic inflammation, we observed significantly greater illness and subacute mortality in gp91phox−/y(NOX2-deficient) mice compared with wild-type mice. Cellular analysis revealed continued neutrophil recruitment to the peritoneum and lungs of the NOX2-deficient mice and altered activation states of both neutrophils and macrophages. Histological examination showed multiple organ pathology indicative of MODS in the NOX2-deficient mice, and several inflammatory cytokines were elevated in lungs of the NOX2-deficient mice. Overall, these data suggest that NOX2 function protects against the development of MODS and is required for normal resolution of systemic inflammation.

Acute necrotizing pancreatitis (ANP) is associated with significantlyhighermorbidity and mortality. It is still difficult for the surgeon to choose and schedule the most appropriate treatment.In the early phase of the disease, surgical activity is considered to be ineffective and is associated with high risks. The only chance to save the patient is to conduct the intensive therapy in the intensive care unit, based on current pathogenetic approaches. The present review analyzed the current understanding of the pathogenesis of multiple organ dysfunction syndrome (MODS) in acute necrotizing pancreatitis. The role of inflammatory mediators, cytokines, biogenic amines, bradykinins, and lipid peroxidation products in the development of organ hypoperfusion is reflected. It is shown that the violation of the intestinal barrier function with the translocation of microorganisms exacerbates endogenous intoxication and contributes to the development of MODS. The endothelial dysfunction that develops in acute necrotizing pancreatitis has a significant effect on hemostasis. The literature analysis revealed the contradictory data on the functional activity of the coagulation and anticoagulation systems at different stages of the disease. The mechanisms of development of intra-abdominal hypertension and its multisystem negative impact are reflected. There are still controversialquestionof appropriatetiming and indications for surgical decompression. The analysis of the available literature data showed the need for further study of the mechanisms of multiple organ dysfunction development in acute necrotizing pancreatitis to work out new pathogenetically justified methods of its intensive therapy with an assessment of their effectiveness.

Dauginis organų nepakankamumo sindromas yra viena iš pagrindinių reanimacijos ir intensyviosios terapijos skyrių ligonių mirties priežasčių. Didėjant pažeistų organų sistemų skaičiui didėja ir mirštamumas. Nors pasiekta didelė pažanga gydant dauginį organų nepakankamumo sindromą (šiuolaikiniai dirbtinės plaučių ventiliacijos režimai, inkstų, kepenų pakaitinės terapijos metodai, ekstrakorporinė membraninė oksigenacija ir kiti gydymo būdai), tačiau ligonių, turinčių daugiau nei keturių organų nepakankamumą, mirštamumas viršija 70 % Todėl tikslinga daugiau dėmesio skirti organų nepakankamumo prevencijai ir ankstyvam kritinės būklės atpažinimui. Žalingas padidėjusio intraabdominalinio spaudimo poveikis visoms organų sistemoms yra įrodytas tiek eksperimentiniais tyrimais su gyvūnais, tiek klinikiniais tyrimais. Intraabdominalinė hipertenzija atlieka svarbų vaidmenį dauginio organų disfunkcijos sindromo patogenezėje, todėl intaabdominalinio spaudimo matavimas tapo rutininiu sunkios būklės ligonių stebėsenos rodikliu. Šioje apžvalgoje, remiantis naujausios literatūros duomenimis, apibendrinami intraabdominalinės hipertenzijos ir pilvo suspaudimo sindromo apibrėžimai, etiologija ir rizikos veiksniai, taip pat įvairūs intraabdominalinio spaudimo matavimo metodai, aptariamas intraabdominalinės hipertenzijos poveikis organų funkcijoms ir šiuolaikinės jos gydymo tendencijos.Reikšminiai žodžiai: intraabdominalinė hipertenzija, intraabdominalinis spaudimas, pilvo suspaudimo sindromas, dauginis organų disfunkcijos sindromas, dekompresinė laparotomija.Intra-abdominal hypertension and the abdominal compartment syndrome: diagnostics, effects on organ function and management The multiple organ dysfunction syndrome is one of the main causes of death in intensive care units. The more organ systems are injured the higher are mortality rates. Although there has been a significant progress in treating the multiple organ dysfunction syndrome (modern modes of mechanical lung ventilation, kidney, liver replacement therapy, extracorporeal membrane oxygenation and other techniques), the mortality rate in patients with more than four organ failures exceeds 70%. Therefore, it is reasonable to pay more attention to the prevention and early recognition of a critical illness. When the measurement of intra-abdominal pressure gradually became available in day-to-day practice, an increasing number of experimental animal testing and clinical trials have proved detrimental effects of the elevated intra-abdominal pressure on all organ systems and its role in the pathogenesis of the multiple organ dysfunction syndrome. In this review, we summarize the current literature data concerning the definitions, etiology and risk factors of intra-abdominal hypertension and the abdominal compartment syndrome as well as different techniques to measure the intra-abdominal pressure. We also discuss the pathophysiological implications of intra-abdominal hypertension on organ function and current treatment trends.Key words: intra-abdominal hypertension, intra-abdominal pressure, abdominal compartment syndrome, multiple organ dysfunction syndrome, decompressive laparotomy
