Patients with severe sepsis assigned to fluid resuscitation with HES 130/0.42 had an increased risk of death at day 90 and were more likely to require renal-replacement therapy, as compared with those receiving Ringer's acetate. (Funded by the Danish Research Council and others; 6S ClinicalTrials.gov number, NCT00962156.).

Among patients with septic shock, mortality at 90 days and rates of ischemic events and use of life support were similar among those assigned to blood transfusion at a higher hemoglobin threshold and those assigned to blood transfusion at a lower threshold; the latter group received fewer transfusions. (Funded by the Danish Strategic Research Council and others; TRISS ClinicalTrials.gov number, NCT01485315.).

EGDN did not appear to affect physical quality of life at 6 months or other important outcomes as compared to standard nutrition care in acutely admitted, mechanically ventilated, adult ICU patients. Clinicaltrials.gov identifier no. NCT01372176.

Polymorphisms in the MBL2 gene, which affect the structure and influence on the serum concentration of mannose-binding lectin (MBL), are associated with inflammatory and infectious conditions. The importance of MBL2 polymorphisms on outcome in critical ill patients is unclear. Five hundred and thirty-two consecutive critically ill patients admitted to an intensive care unit (ICU) were included over a period of 18 months. Five hundred and thirty-three individuals served as controls. Vital status was obtained 15.5 months after the last patient was included. MBL2 polymorphisms were determined by a PCR-based assay. Homozygosity for MBL2 variant alleles (O/O) causing MBL structural defects was associated with the highest adjusted mortality rate followed by homozygosity for the normal MBL2 allele (A/A) encoding high MBL levels, whereas heterozygous A/O patients had the most favourable outcome (P = 0.015). MBL2 alleles were not associated with death in ICU (n = 166, P = 0.7), but the association appeared soon after discharge from ICU (n = 366): hazard ratio (HR) for O/O using A/A as reference was 1.33 (95% CI: 0.8-2.2) and for A/O it was 0.62 (95% CI: 0.4-0.8) respectively (P = 0.0045) at completion. No difference in MBL2 frequency was observed between patients and controls at baseline, and between patients classified as having sepsis or not. However, patients with the MBL2 O/O genotype had an increased frequency of Gram-positive bacterial infection (P = 0.01). Heterozygosity for MBL2 alleles confers a protective effect whereas homozygosity is associated with the worst outcome soon after discharge from ICU. This may be an example of heterosis.

Recombinant-activated factor VII (rFVIIa) represents a therapeutic advance for the treatment and prevention of haemorrhage in patients with the rare bleeding disorder, congenital FVII deficiency. Thirty-nine cases of the use of rFVIIa in 30 patients with congenital FVII deficiency were identified from the international, internet-based registry haemostasis.com, which is a repository of case reports on the investigational use of rFVIIa that have been voluntarily submitted by physicians worldwide. These registry data have limitations compared with clinical-trial data but give valuable insights into a treatment for a rare disease that is virtually impossible to assess in conventional clinical trials. rFVIIa was used in: elective surgery (13 cases); haematoma (9 cases); emergency surgery (6 cases); epistaxis (4 cases); menorrhagia (2 cases); cover during childbirth (2 cases); disseminated intravascular coagulation (1 case; premature infant); removal of intradermal stitches (1 case); and haematuria (1 case). In 22/39 cases, rFVIIa was used prophylactically. Total dose and dosing schedules varied; median individual dose was 13.3 mug/kg body weight (bw) (range 1.2-223.8 mug/kg bw), median total dose was 38 microg/kg bw (range 1.2-758 microg/kg bw) and median number of doses was 3 (range 1-55). rFVIIa was generally associated with bleeding cessation or markedly reduced bleeding. Two adverse events were reported, but neither was regarded as being related to rFVIIa. These 39 cases support data confirming the safety and efficacy of rFVIIa in its EU-licensed indications, including that for preventing and/or controlling haemorrhage in patients with congenital FVII deficiency.

Background: Rhabdomyolysis-induced acute kidney injury (AKI) is a common and serious condition. We aimed to summarise the available evidence on this topic and provide recommendations according to current standards for trustworthy guidelines. Methods: This guideline was developed using Grading of RecommendationsAssessment, Development, and Evaluation (GRADE). The following preventive interventions were assessed: (a) fluids, (b) diuretics, (c) alkalinisation, (d) antioxidants, and (e) renal replacement therapy. Exclusively patient-important outcomes were assessed. Results:We suggest using early rather than late fluid resuscitation (weak recommendation, very low quality of evidence). We suggest using crystalloids rather than colloids (weak recommendation, low quality of evidence). We suggest against routine use of loop diuretics as compared to none (weak recommendation, very low quality of evidence). We suggest against use of mannitol as compared to none (weak recommendation, very low quality of evidence). We suggest against routine use of any diuretic as compared to none (weak recommendation, very low quality of evidence). We suggest against routine use of alkalinisation with sodium bicarbonate as compared to none (weak recommendation, low quality of evidence). We suggest against the routine use of any alkalinisation as compared to none (weak recommendation, low quality of evidence). We suggest against routine use of renal replacement therapy as compared to none (weak recommendation, low quality of evidence). For the remaining PICO questions, no recommendations were issued. Conclusion:The quantity and quality of evidence supporting preventive interventions for rhabdomyolysis-induced AKI is low/very low. We were able to issue eight weak recommendations and no strong recommendations.
