Multiorgan Dysfunction Syndrome

Polyacrylonitrile (AN69) filter membranes adsorb cytokines during continuous venovenous hemofiltration (CVVH). Although high-volume hemofiltration has shown limited benefits, the dose-effect relationship in CVVH with AN69 membranes on severe sepsis remains undetermined. This multi-centered study enrolled 266 patients with sepsis-induced multiorgan dysfunction syndrome (MODS) who underwent CVVH with AN69 membranes between 2014 and 2015. We investigated the effects of ultrafiltration rates (UFR) on mortality. We categorized patients that were treated with UFR of 20–25 mL/kg/h as the standard UFR group (n = 124) and those that were treated with a UFR >25 mL/kg/h as the high UFR group (n = 142). Among the patient characteristics, the baseline estimated glomerular filtration rates (eGFR) <60 mL/min/1.73 m2, hemoglobin levels <10 g/dL, and a sequential organ failure assessment (SOFA) score ≥15 at CVVH initiation were independently associated with in-hospital mortality. In the subgroup analysis, for patients with SOFA scores that were ≥15, the 90-day survival rate was higher in the high UFR group than in the standard UFR group (HR 0.54, CI: 0.36–0.79, p = 0.005). We concluded that in patients with sepsis-induced MODS, SOFA scores ≥15 predicted a poor rate of survival. High UFR setting >25 mL/kg/h in CVVH with AN69 membranes may reduce the mortality risk in these high-risk patients.

Background: While recommended timing of pegfilgrastim administration is ≥24 h after chemotherapy, patient barriers to next day administration, available adult evidence, and pharmacokinetic data have led to earlier administration in some pediatric patients with solid and central nervous system tumors. The purpose of this study was to compare patient outcomes by timing of pegfilgrastim after chemotherapy. Methods: A retrospective chart review examined timing of 932 pegfilgrastim administrations to 182 patients, 0–29 years of age. The primary outcome was febrile neutropenia (FN); the secondary outcome was neutropenic delays (ND) ≥7 days to next chemotherapy cycle. To account for multiple pegfilgrastim administrations per patient, a generalized mixed model was used with a logit link for the dichotomous outcomes (FN & ND), timing as the dichotomous independent variable, and random effect for patient. Results: FN occurred in 196 of 916 cycles (21.4%); and ND in 19 of 805 cycles (2.4%). The fixed effect of pegfilgrastim administration < or ≥24 h after chemotherapy was not significant, p = .50; however, earlier or later than 20 h was significant, p = .005. FN odds were significantly higher when pegfilgrastim was given <20 h (OR 1.78, 95% CI: 1.19–2.65) after chemotherapy, which may be attributable to differences in chemotherapy toxicity regardless of pegfilgrastim timing. Discussion: While attempts should be made to administer pegfilgrastim ≥24 h after chemotherapy, if barriers exist, modified timing based on individual patient characteristics should be considered. Prospective randomized trials are needed to identify lower risk patients for early pegfilgrastim administration.

Abstract BackgroundThis study evaluated the performance of a novel fast broad range PCR and sequencing (FBR-PCR/S) assay for the improved diagnosis of invasive fungal disease (IFD) in high-risk patients in a large Canadian healthcare region.MethodsA total of 114 clinical specimens (CS) including bronchoalveolar lavages (BALs) were prospectively tested from 107 patients over a 2-year period. Contrived BALs (n=33) inoculated with known fungi pathogens were also tested to increase diversity. Patient characteristics, fungal stain and culture results were collected from the laboratory information system. Dual-priming oligonucleotide (DPO) primers targeted to the ITS (~350 bp) and LSU (~550 bp) gene regions were used to perform FBR-PCR/S assays on extracted BALs/CS. The performance of the molecular test was evaluated against results of fungal stains and culture, and where available, histopathology, and clinical review for the presence of IFD.ResultsThe 107 patients were predominantly male (67, 62.6%%) with a mean age of 59 yrs. (range = 0 to 85 yrs.): 74 (69.2%) patients had at least one underlying comorbidity: 19 (34.5%) had confirmed and 12 (21.8%) had probable IFD. Culture recovered 66 fungal isolates from 55 BALs/CS with Candida spp. and Aspergillus spp. being most common. For BALs, the molecular assay vs. fungal culture had sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), and efficiency of 88.5% vs.100%, 100% vs. 61.1%, 100% vs. 88.5%, 61.1% vs. 100%, and 90.2% for both. For other CS, the molecular assay had similar performance to fungal culture with sensitivity, specificity, PPV, NPV and efficiency of 66.7%, 87.0%, 66.7%, 87.0% and 81.3% for both methods. Both methods also performed similarly, regardless of whether CS stain/microscopy showed yeast/fungal elements. FBR-PCR/S assays results were reported in ~8h compared to fungal cultures that took between 4 to 6 weeks.ConclusionsRapid molecular testing compared to culture has equivalent diagnostic efficiency but improves clinical utility by reporting a rapid species-level identification the same dayshift (~8h).

Background/Aim: Here, we investigated whether bortezomib as a maintenance therapy affected outcomes in transplant-ineligible patients with multiple myeloma (MM). Patients and Methods: Following induction therapy with bortezomib, maintenance therapy with bortezomib (1.3 mg/m2) and dexamethasone (20 mg) was administered once or twice every 4 weeks until disease progression. The endpoints of this study were time to next treatment and overall survival. Results: Seventy-six newly diagnosed, transplant-ineligible patients were treated with a bortezomib-based regimen; 28 discontinued induction therapy, 27 did not receive maintenance therapy after induction therapy (the non-maintenance group), and 21 did (the maintenance group). In the three groups, the median times to the next required treatment were 3, 14, and 37 months, respectively. The 3-year overall survival rates were 55%, 69%, and 85%, respectively. There were no significant differences in patient characteristics between the non-maintenance and maintenance groups, except for poorer estimated glomerular filtration rates in the maintenance group. Conclusion: Bortezomib maintenance therapy may be a useful option for transplant-ineligible patients with MM.
