METHODS: We systematically searched MEDLINE, EMBASE, and CENTRAL from inception to 01/06/2023 for relevant randomised controlled trials (RCTs) and non-randomised studies of intervention (NRSI). The primary outcome was overall mortality. Random effect meta-analyses were conducted in RevMan 5.4.1. Study quality was evaluated using Cochrane's risk of bias tool. (PROSPERO: CRD42023389198).
RESULTS: Ten studies (2 RCTs and 8 NRSIs) with 481 patients were included. None had low risk of bias. Treatment using oXiris® was associated with reduced overall mortality (RR 0.78, 95%CI 0.62-0.98; p = 0.03; 6 NRSI). One RCT reported 28-day mortality, finding no significant difference between groups. Besides, pooled NRSIs results showed significant reductions in SOFA scores, norepinephrine dosage, and several inflammatory biomarkers (C-reactive protein [CRP], lactate, and interleukin-6 [IL-6]) post oXiris® treatment. However, other clinical outcomes (ICU and hospital length of stay, mechanical ventilation duration) were similar between groups.
CONCLUSION: In critically ill patients, the use of oXiris® membrane was associated with reduced overall mortality, norepinephrine dosage, CRP, IL-6, lactate levels, along with improved organ function. However, the certainty of evidence was very low, necessitating high-quality RCTs to further evaluate its efficacy in this population.
METHODS: We analyzed data from the India and Southeast Asia Renal Replacement Therapy (InSEA-RRT) registry, a multicenter cohort study conducted between April 2019 and December 2023 across 24 hospitals in Southeast Asia and India. Critically ill patients with AKI stage 3, as defined by the Kidney Disease Improving Global Outcomes (KDIGO) criteria, were enrolled. The primary outcome was 2-year MAKE, defined as a composite of persistent kidney dysfunction, long-term dialysis, and all-cause mortality at 2 years post-enrollment.
RESULTS: A total of 2,315 patients were enrolled, of whom 1,033 (47%) died during hospitalization. Among surviving patients, the incidence of 2-year MAKE was 46.6 per 100 person-years (95% CI 42.7-50.6). Notably, mortality (32%) was the dominant component of MAKE. The incidence of new chronic kidney disease (CKD) and CKD progression at 2 years post-AKI was 58.6 and 35.4 per 100 person-year (95% CI 51.0-67.0 and 26.0-47.0), respectively. Multivariable-adjusted models identified older age, male sex, preexisting CKD, malignancy, cardiac-associated AKI, and non-recovery of kidney function after AKI as independent risk factors for 2-year MAKE.
CONCLUSIONS: Patients with severe AKI face a high incidence of 2-year MAKE and poor long-term clinical outcomes. Early recognition and close follow-up of these patients are crucial. Further research is needed to identify effective strategies to improve long-term outcomes in this high-risk population.
