    BACKGROUND: Prolonged duration of polymyxin B hemoperfusion (PMX-HP) for septic shock is not widely investigated. METHODS: We used BEAT-SHOCK, a prospective registry including 309 adult patients with septic shock requiring high-dose norepinephrine (≥ 0.2 μg/kg/min). Our post hoc analysis included 82 patients that underwent PMX-HP, dichotomized into either the ultra-long PMX-HP group (first session duration ≥ 12 h; n = 53) or the non-ultra-long PMX-HP group (< 12 h; n = 29). The primary outcomes were changes in vasopressor/inotrope dosage, represented by vasoactive-inotropic score (VIS), and sequential organ failure assessment (SOFA) score from baseline to day 3. RESULTS: The median durations of the first PMX-HP session in the ultra-long and non-ultra-long PMX-HP groups were 1290 and 358 min, respectively. Their median baseline VIS was 38.3 (IQR 26.0-49.5) in the ultra-long group, 38.1 (IQR 30.9-55.6) in the non-ultra-long PMX-HP group. The median baseline SOFA score was 11 (IQR 9-13) in both groups. The changes in these scores from baseline to day 3 did not differ between them (adjusted difference -3.8 [95% confidence interval -9.0 to 11.3] for VIS and -0.0 [95% confidence interval -1.5 to 1.5] for SOFA score). The 90-day mortality rate was 24.7% in the ultra-long PMX-HP group and 21.1% in the non-ultra-long PMX-HP group (adjusted hazard ratio 1.35; 95% confidence interval 0.49-3.69). CONCLUSIONS: Ultra-prolonged PMX-HP for ≥ 12 h was not associated with a greater reduction in vasopressor/inotrope dosage or improvement in organ dysfunction on day 3 than PMX-HP < 12 h in our patients with septic shock without endotoxin monitoring.

    Aim There are few assessments of sedatives during the acute phase under sedation protocols for patients with sepsis. We aimed to compare the influence of different sedation strategies using midazolam and propofol under light sedation on clinical outcomes of ventilated patients with sepsis. Methods This study was a post‐hoc analysis of data from the dexmedetomidine for sepsis in the ICU Randomized Evaluation (DESIRE) trial. Patients were divided into propofol and midazolam groups based on continuously used drug, and sedation control between groups compared on day three. We assessed the incidence of delirium, length of ICU stay, number of ventilator‐free days within the first 28 days, and mortality after 28 days. Results The midazolam and propofol groups consisted of 51 and 66 patients, respectively. Both groups had similar characteristics, except for age and emergency surgery. The number of well‐controlled sedation patients in the propofol group on day three was significantly higher than that in the midazolam group (odds ratio [OR] 3.9, 95% CI [1.30, 11.7]). The incidence of daily coma and delirium within the initial week was different between groups and increased with midazolam administration (P = 0.0138). The number of Confusion Assessment Method for ICU‐positive patients was significantly higher in the midazolam group than in the propofol group (OR 5.71, 95% CI [2.30, 14.2]). Conclusion In patients with sepsis required mechanical ventilation, sedation with midazolam based on a light sedation protocol may be associated with inappropriate sedation during the acute phase, with increased coma and delirium as compared to propofol.

    BACKGROUND: The distribution of body mass in populations of Western countries differs from that of populations of East Asian countries. In East Asian countries, fewer people have a high body mass index than those in Western countries. In Japan, the country with the highest number of older adults worldwide, many people have a low body mass index. Therefore, this study aimed to determine the association between a low body mass index and mortality in patients with sepsis in Japan. METHODS: We conducted this retrospective analysis of 548 patients with severe sepsis from a multicenter prospective observational study. Multivariate logistic regression analyses determined the association between body mass index and 28-day mortality adjusted for age, sex, pre-existing conditions, the occurrence of septic shock, Acute Physiology and Chronic Health Evaluation II scores, and Sequential Organ Failure Assessment scores. Furthermore, the association between a low body mass index and 28-day mortality was analyzed. RESULTS: The low body mass index group represented 18.8% of the study population (103/548); the normal body mass index group, 57.3% (314/548); and the high body mass index group, 23.9% (131/548), with the 28-day mortality rates being 21.4% (22/103), 11.2% (35/314), and 14.5% (19/131), respectively. In the low body mass index group, the crude and adjusted odds ratios (95% confidence intervals) for 28-day mortality relative to the non-low body mass index (normal and high body mass index groups combined) group were 2.0 (1.1-3.4) and 2.3 (1.2-4.2), respectively. CONCLUSION: A low body mass index was found to be associated with a higher 28-day mortality than the non-low body mass index in patients with sepsis in Japan. Given that older adults often have a low body mass index, these patients should be monitored closely to reduce the occurrence of negative outcomes.

    Peripheral blood (PB) contains several types of stem/progenitor cells, including hematopoietic stem and endothelial progenitor cells. We identified a population positive for both the pluripotent surface marker SSEA-3 and leukocyte common antigen CD45 that comprises 0.04% ± 0.003% of the mononuclear cells in human PB. The average size of the SSEA-3(+)/CD45(+) cells was 10.1 ± 0.3 µm and ∼22% were positive for CD105, a mesenchymal marker; ∼85% were positive for CD19, a B cell marker; and ∼94% were positive for HLA-DR, a major histocompatibility complex class II molecule relevant to antigen presentation. These SSEA-3(+)/CD45(+) cells expressed the pluripotency markers Nanog, Oct3/4, and Sox2, as well as sphingosine-1-phosphate (S1P) receptor 2, and migrated toward S1P, although their adherence and proliferative activities in vitro were low. They expressed NeuN at 7 d, Pax7 and desmin at 7 d, and alpha-fetoprotein and cytokeratin-19 at 3 d when supplied to mouse damaged tissues of the brain, skeletal muscle and liver, respectively, suggesting the ability to spontaneously differentiate into triploblastic lineages compatible to the tissue microenvironment. Multilineage-differentiating stress enduring (Muse) cells, identified as SSEA-3(+) in tissues such as the bone marrow and organ connective tissues, express pluripotency markers, migrate to sites of damage via the S1P-S1P receptor 2 system, and differentiate spontaneously into tissue-compatible cells after homing to the damaged tissue where they participate in tissue repair. After the onset of acute myocardial infarction and stroke, patients are reported to have an increase in the number of SSEA-3(+) cells in the PB. The SSEA-3(+)/CD45(+) cells in the PB showed similarity to tissue-Muse cells, although with difference in surface marker expression and cellular properties. Thus, these findings suggest that human PB contains a subset of cells that are distinct from known stem/progenitor cells, and that CD45(+)-mononuclear cells in the PB comprise a novel subpopulation of cells that express pluripotency markers.

    PURPOSE: Disseminated intravascular coagulations (DIC), acute respiratory distress syndrome (ARDS), and acute kidney injury (AKI) are major organ dysfunctions that occur in patients with sepsis. This study aimed to elucidate the impact of these organ dysfunctions on mortality in patients with severe sepsis. MATERIAL AND METHODS: A prospective observational study was performed in 10 ICUs to obtain data from patients with severe sepsis. Multivariate analyses to examine in-hospital mortality were performed. RESULTS: Data of 573 patients were analyzed. In-hospital mortality rate was 19.4% (111/573). The incidences of DIC, ARDS, and AKI were 58.4%, 18.7%, and 41.7%, while the associated mortality rates were 28.9%, 36.4%, and 31.8%, respectively. In multiple regression model, DIC (odds ratio 2.71, 95% confidence interval [CI] 1.45-5.27) and AKI stage 3 (odds ratio 1.98, 95% CI 1.07-3.63) were significantly associated with higher in-hospital all-cause mortality. DIC (hazard ratio 2.58, 95% CI 1.53-4.55) and AKI stage 3 (hazard ratio 1.73, 95% CI 1.07-2.80) were also significantly associated with longer survival durations. However, severe ARDS was not associated with these outcomes. CONCLUSIONS: DIC and AKI are frequent complications in patients with severe sepsis. In this study, DIC, and AKI stage 3 were independent risk factors of in-hospital mortality.
