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: The Association of VA and intervenTionAl Renal physicians (AVATAR) Foundation from India conducted a multinational online survey amongst nephrologists from the Asia-Pacific to determine the practice of IN in the planning, creation, and management of dialysis access. The treatment modalities, manpower and equipment availability, monthly cost of treatment, specifics of dialysis access interventions, and challenges in the training and practice of IN by nephrologists were included in the survey.
RESULTS: Twenty-one countries from the APR participated in the survey. Nephrologists from 18 (85.7%) countries reported performing at least one of the basic dialysis access-related IN procedures, primarily the placement of non-tunnelled central catheters (n-TCC; 71.5%). Only 10 countries (47.6%) reported having an average of <4% of nephrologists performing any of the advanced IN access procedures, the most common being the placement of a peritoneal dialysis (PD) catheter (20%). Lack of formal training (57.14%), time (42.8%), incentive (38%), institutional support (38%), medico-legal protection (28.6%), and prohibitive cost (23.8%) were the main challenges to practice IN. The primary obstacles to implementing the IN training were a lack of funding and skilled personnel.
CONCLUSION: The practice of dialysis access-related IN in APR is inadequate, mostly due to a lack of training, backup support, and economic constraints, whereas training in access-related IN is constrained by a lack of a skilled workforce and finances.
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.
