Abstract:Systemic inflammatory response syndrome (SIRS) with activation of molecular cascades, cell activation, accumulation of interstitial fluid, organ dysfunction and, occasionally, organ failure is still a commonly recognized consequence of cardiac surgery. SIRS leads to costly complications and several strategies intended to ameliorate the symptoms that have been studied, including leukocyte reduction, using filtration. Although, the body of work suggests that leukoreduction attenuates SIRS, discrepancies remain w… Show more
“…In addition, there was less need for inotropic support and IABP in the filtered groups. These findings were consistent with previous research [22]. Mechanical interventions do not affect organ function, but full-dose aprotinin in clinically ill patients may interfere with metabolic activities in the early post-CPB period.…”
Leukofiltration on coated circuits significantly reduced bleeding and inflammatory response related to CPB with no adverse effects, and may be a possible alternative to pharmacological intervention.

“…Our previous studies indicated that leukocyte filters on uncoated circuits caused a pressure difference and platelet destruction (5,17,18). The uncoated surface induced an activation of platelets and complemented the inflammatory process.…”

“…Also filtration efficiency and duration was much better with additional coating. In our previous studies, we have compared leukocyte filtration on coated and uncoated circuits and concluded that leukofiltration on uncoated circuits did not have any additional advantage, even interfered platelet preservation (17,18).…”
“…Accumulating evidence have suggested that a subgroup of patients with severe COVID-19 may have a cytokine storm syndrome. [3] We recommend identification and treatment of hyperinflammation using existing, approved therapies with proven safety profiles to address the immediate need to reduce the rising mortality rates. Secondary hemophagocytic lymphohistiocytosis is a syndrome characterized by a fulminant and fatal hypercytokinemia associated with multiorgan failure.…”

“…Cytokine filtration (extracorporeal blood purification) is approved by the United States Food and Drug Administration (FDA) to treat patients 18 years of age or older with confirmed COVID-19 admitted to the operating room/intensive care unit with confirmed or imminent respiratory failure to reduce pro-inflammatory cytokines levels. [3] The issue of potential risk for aerosolization/ contamination of virus via oxygenator/chest drains is also an under-recognized means of viral spread, which may put patients and healthcare professionals at an utmost risk for infection. Although most membrane oxygenators used today are surface coated, there is no evidence-based in the literature to suggest that viruses cannot permeate these hollow fiber materials.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
