BACKGROUND AND AIM The choice of resuscitation fluid in cirrhosis patients with sepsis-induced hypotension (SIH) is unclear. 5% albumin has been superior to normal saline in the FRISC study. We compared the efficacy and safety of 20% albumin, which has greater oncotic properties with plasmalyte in reversing SIH. METHODS Critically-ill cirrhosis(CIC) patients underwent open-label randomization to receive either 20% albumin
[0.5-1.0gm/kg over 3 hours; n=50] or plasmalyte (30ml/kg over 3 hours, n=50). The primary end-point of the study was the attainment of mean arterial pressure (MAP) above 65 mmHg at three hours. RESULTS Baseline characteristics were comparable in albumin and plasmalyte groups; arterial lactate(mmol/L) [6.16±3.18 vs. 6.38±4.77; p=0.78), MAP (mmHg) [51.4±6.52 vs. 49.9±4.45; p=0.17] and SOFA score [10.8±2.96 vs. 11.1±4.2; p=0.68] respectively. Most patients were alcoholics (39%) and had pneumonia (40%). In the intention-to-treat (ITT) analysis, albumin was superior to plasmalyte in achieving the primary end-point (62% vs. 22%; p<0.001). A rapid decline in arterial lactate (P=0.03), a lesser proportion of dialysis [48% vs. 62%; p=0.16], and a higher time to initiation of dialysis (in hours) [68.13±47.79 vs. 99.7± 63.4; p=0.06] was seen with albumin. However, the 28-day mortality was not different (58% vs. 62%, p=0.57). Patients in the albumin group required discontinuation of therapy in 11 (22%) patients due to adverse effects compared to none in plasmalyte group. CONCLUSION In patients with cirrhosis and SIH, 20% albumin transiently improves the hemodynamics with early lactate clearance than plasmalyte but needs monitoring as it is more often attended with pulmonary complications. Both fluids provide comparable 28 days survival. NCT02721238 LAY SUMMARY The current randomized controlled trial performed in critically ill patients with cirrhosis and sepsis-induced hypotension highlights that 20% albumin restores hemodynamics but causes more pulmonary complications than plasmalyte. The impact on renal functions was also modest. These effects did not result in improvement in deaths at 28-days. Plasmalyte is safer and well-tolerated and can be considered for volume resuscitation in patients with cirrhosis and sepsis-induced hypotension.
