Comparing adsorptive blood purification modalities for sepsis patients: A systematic review and network meta-analysis.

PURPOSE: Hemoadsorption is a promising therapeutic modality for sepsis, however, the most effective approach is unknown. This meta-analysis aimed to compare the efficacy of different adsorptive blood purification (ABP) modalities in patients with sepsis.

MATERIALS AND

METHODS

Randomized controlled trials (RCTs) investigating the clinical efficacy of ABP modalities in patients with sepsis were retrieved from English databases from inception up to October 14, 2024. The data were analyzed using Stata15 and R software. Quality assessment and publication bias were assessed using the Cochrane Risk of Bias Assessment Tool and funnel plots, respectively. The outcomes of the meta-analysis were hospital mortality, oxygenation index, ICU stay days, and blood lactate concentration.

RESULTS

A total of 47 RCTs were identified, comprising 9 ABP modalities. In terms of cumulative ranking probability, the HA330 modality achieved the highest reduction in hospital mortality (99.5 %) and ICU stay days (97.2 %), whereas CPFA showed the highest reduction in oxygenation index (94.9 %) and oXiris had the highest reduction in lactate (95.7 %).

CONCLUSIONS

HA330 and PMX showed superior overall efficacy in sepsis patients compared with other modalities, although there was potential heterogeneity. However, further RCTs with large samples are advocated to test new approaches of hemosorption and validate the present findings.
