ALBIOS: Albumin Replacement in Patients with Severe Sepsis or Septic Shock
Caironi et al for the ALBIOS Study Investigators. N Engl J Med 2014; 370(15):1412–21.
Clinical Question
- In adults with severe sepsis or septic shock, does 20% albumin solution with crystalloid fluid compared to crystalloid fluid alone reduce death with 28 days?
Design
- Randomised, controlled clinical trial
- Stratified according to participating ICU and time between onset of sepsis and randomisation (<6 hours vs >6 hours)
- Open-label (non-blinded)
Setting
- 100 intensive care units in Italy
- August 2008 to February 2012
Population
- Inclusion: adults who met the clinical criteria for severe sepsis (SIRS + proven or suspected infection + at least one organ dysfunction as measured by SOFA score)
- Exclusions: Head injury, congestive heart failure, over 24 hours since inclusion criteria met, objection to blood products, albumin indicated for specific clinical reason.
- 1818 participants
Intervention
- 20% albumin and crystalloid solution
- 300ml of 20% albumin daily to maintain serum albumin at 30 g/l or more
- Crystalloid as clinically indicated at physician’s discretion
- 20% albumin accounted for median daily average of 4.3% of the total administered fluid
- Median total daily fluid was 3,738ml for first 7 days (compared with control this was a non-statistically significant difference [p=0.10])
Control
- Crystalloid as clinically indicated at physician’s discretion
- Median total daily fluid was 3,825ml for first 7 days
Outcome
- Primary outcome: mortality at 28 days was not different between groups
- 31.8% in albumin group versus 32.0% in crystalloid group; RR 1.00 (CI 0.87–1.14; p=0.94).
- Secondary outcome: mortality at 90 days was not different between groups
Authors’ Conclusions
- The addition of albumin to crystalloids during the first 28 days of treatment to maintain a serum albumin level of 30 g/l or more is safe, but does not provide a survival advantage over crystalloids alone over a follow-up period of 90 days
Strengths
- Pragmatic study directly relevant to clinical practice.
- Only 29 participants lost-to-follow-up (1.6%), which is well below primary outcome rate (minimal attrition bias).
Weaknesses
- Open-label, non-blinded methodology may have influenced clinicians’ decisions, which may have biased toward either intervention or control.
- Lower incidence of death compared to anticipated rate (45% used in power calculation) may have lead to type 2 error (failure to detect a true positive outcome).
The Bottom Line
- The use of 20% albumin in adults with severe sepsis will improve haemodynamic indices, but will not reduce mortality. It’s use is safe but not recommended for routine fluid resuscitation. Targeting a serum albumin of 30g/l or more does not appear to have a survival advantage.
