  ABSTRACT: A monoacetyldiglyceride (MADG) markedly improves survival in a murine model of abdominal sepsis. MADGs have been shown to stimulate hematopoiesis in vitro. We examined effects of MADG administration in setting of cecal ligation and puncture (CLP) and hypothesized that oral (p.o.) administration of MADG would result in alterations of cytokine and chemokine expression after CLP. Four groups of 20 mice: sham group underwent celiotomy but not CLP; control group underwent CLP and administration of phosphate buffer solution; simultaneous treatment group had administration of 50 mg/kg MADG p.o. Immediately, before CLP and at 24, 48, and 72-hour post-CLP, posttreatment group had initial administration of MADG at 1-hour post-CLP, and at 24, 48, and 72-hour postoperative. We followed survival to 10-day postoperative. Serum and tissue levels of pro- and anti-inflammatory cytokines were measured. Serum levels of chemokines stromal cell-derived factor (SDF-1) and stem cell factor (SCF) were measured to ascertain if effects of MADG involve stimulation of bone marrow stromal and stem cells. Polymerase chain reaction was used to measure SDF and SCF mRNA expression in liver and lung. Administration of MADG (p.o.) significantly improved survival in mice after CLP with associated systemic alterations of a variety of cytokines. Increased levels of mRNA coding for SCF and SDF in lung and liver were found after CLP. Administration of MADG (p.o.) after CLP results in marked improvement in survival. Cytokine level changes demonstrate associated immunomodulatory effects. These effects may be mediated by bone marrow stromal and stem cell activation, evidenced by increases in SDF and SCF. Further study of behavior of bone marrow-derived stem cells in setting of sepsis is warranted. MADG may hold promise for use in treatment of sepsis.

  ABSTRACT: Hepatic angiography (HA) and hepatic angioembolization (HAE) are increasingly used to diagnose and treat intrahepatic arterial injuries. This study was performed to review indications, outcomes, and complications of HA/HAE in blunt trauma patients who underwent HAE as adjunct management of hepatic injury. A retrospective review of consecutive cases of HA/HAE at a Level I trauma center during an 8-year period. Data include demographics, physiologic condition, liver injury grade, HA/HAE indications, outcomes, morbidity, and mortality. Seventy-nine patients underwent diagnostic HA; 31 (39%) had subsequent HAE. Fifty-eight hemodynamically stable patients had computerized axial tomographic (CT) scan followed by HA. HA was performed for contrast blush on CT in 30 (52%) of 58 patients, high-grade liver injury in 4 (7%), subsequent hemodynamic instability in 15 (27%), and angiography planned for other purpose in 9 (17%). HA confirmed arterial injury and led to HAE in 50% of patients with contrast blush on CT or high-grade liver injury. HA was negative when performed for hemodynamic instability or for other primary purposes. Twenty-one hemodynamically unstable patients underwent emergent laparotomy followed by postoperative HA with 11 (50%) requiring HAE. Overall mortality in HAE group was 16%, and liver-related morbidity was 29% usually presenting as gallbladder or liver necrosis. HA/HAE should be used when CT scan suggests associated intrahepatic arterial or high-grade injury in the management of hepatic injuries and should also be considered after laparotomy and perihepatic packing to control inaccessible intrahepatic hemorrhage. Mortality related to HAE is uncommon, but morbidity occurs frequently.
