Human albumin: ICU


At the moment, there are at least four different large RCTs (either completed, planned or ongoing), which aim at evaluating the possible benefit of albumin administration compared with standard crystalloid infusion in this category of patients (see Table 1). The Early Albumin Resuscitation during Septic Shock – NCT00327704 (EARSS) and the Albumin Italian Outcome Sepsis trial – NCT00707122 (ALBIOS) trials have been recently completed (although still unpublished), whereas the PRECISE

patients, is a Brazilian multicentre, double-blind RCT that planned an enrolment of 360 patients with early severe sepsis, randomised to receive either 4% albumin or ringer lactate for fluid resuscitation. Thus, in the near future, novel findings will have the possibility of clarifying the potential benefits of albumin administration beyond a safe volume effect in case of hypovolaemia in patients with sepsis syndromes. Moreover, these trials, having both similarities and differences, will allow us to better dissect the effects of albumin, in terms of patient characteristics (severe sepsis versus septic shock), adequate timing of treatment (early versus late), adequate trigger for albumin administration (volume versus albumin replacement),

trial has undergone only a pilot phase, pending the publication of the findings observed in the two first trial so as to decide how to proceed.20


In particular,


the EARSS trial is a French multicentre, open-label RCT that enrolled 794 patients with early septic shock randomised to receive either 20% albumin or normal saline for the first three days of fluid resuscitation, at fixed doses (100ml every eight hours). In contrast, the ALBIOS trial is an Italian multicentre, open-label RCT that planned an enrolment of 1800 patients with severe sepsis from 100 Italian ICUs. Patients have been randomised to receive either 20% albumin and crystalloids or crystalloids alone during the first phase of volume replacement and targeting, during the next 28 days, serum albumin concentration equal to or greater than 30g/l.3


Similarly to the


EARSS study, the PRECISE trial (Fluid Resuscitation with 5% albumin versus Normal Saline in Early Septic Shock), designed as a Canadian multicentre, double-blind RCT, has planned to enrol 1800 patients with early septic shock, who will be randomised to receive either 5% albumin or normal saline as fluid challenges during volume resuscitation for a maximal period of 90 days.20

Conclusions


There is a strong biological and physiological rationale on which it is reasonable to hypothesise a potential beneficial effect of human albumin administration in the critically ill. At the same time, the available clinical evidence is limited. A key limiting factor is the large heterogeneity characterising the population of critically ill. Therefore, a crucial next step will be to characterise the effects of albumin administration in specific categories of patient. As an example, it is now recommended that human albumin should not be employed in patients with traumatic brain injury; in contrast, patients with severe sepsis or septic shock may benefit from its use. It is very likely that the upcoming novel findings from recently concluded RCTs will better clarify this issue. l
