Abstract
- Purpose
The objective of this study was to evaluate the effect of Polymyxin B hemoperfusion (PMX-HP) on patients with sepsis.
Methods
A systematic review and meta-analysis was performed using relevant articles retrieved from 3 databases (PubMed, Cochrane Library, EMBASE). Randomized studies from 1 January 1999 to 28 February 2022 were examined to determine the clinical results of PMX-HP. A meta-analysis was carried out using the random-effects method, meta-regression with clinical variables, and assessment of risk of bias (ROB) tool (Cochrane ROB assessment tool). Mortality was evaluated within 60 days of hospitalization (in-hospital death 28-day, 30-day, and 60-day mortality) and predictors associated with mortality were determined using meta-regression.
Results
There were 11 randomized studies with 548 patients included in the meta-analysis. The pooled mortality was 35% (95% CI, 27%-42%, 95% CI 0.53-0.96). Further subgroup analysis was performed according to the duration of PMX-HP. An extension of PMX-HP treatment beyond 2 hours (pooled mortality, 43%; 95% CI, 9%-76%) compared with a 2-hour session (pooled mortality, 33%. 95% CI, 27%-38%) showed an increase in mortality rates. However, this was not statistically significant. Univariate meta-regression showed that patient’s age, the acute physiology and chronic health evaluation score, and the sequential organ failure assessment score did not significantly impact mortality.
Conclusion
While PMX-HP is valuable in the management of septic shock, treatment duration should be based on careful assessment of the patient's condition, the risks and benefits of prolonged therapy, and the overall treatment strategy including antimicrobial management and source control.
