Chasing the Mystery of the Etiology of Acute Kidney Injury in Pediatric Severe Malaria
Acute kidney injury (AKI) is increasingly recognized in pediatric severe malaria, but an understanding of contributory mechanisms is lacking. We evaluated potential hemodynamic contributors to AKI in children with cerebral malaria. Structural AKI was defined using urine neutrophil gelatinase–associated lipocalin (uNGAL) values >125 ng/mL. We included 62 patients (median age 53.5 [31, 71] months), and 38 (61%) had AKI at hospital admission. Blantyre Coma Score <2 (aOR 9.1, 95%CI 1.8-43, P = .003), a low-flow phenotype on transcranial doppler ultrasound (TCD) (aOR 2.3, 95%CI 1.1-7.7, P = .05), and thrombocytopenia <75,000 × 106/L (aOR 4.2, 95%CI 1.3-12.8, P = .03) were associated with AKI. Cardiac index (CI) was lower (P = .01) and systemic vascular resistive index (SVRI) higher (P = .03) in children with AKI compared to those without. AKI was associated with poor outcome (sequelae or death: OR 5.7, 95%CI 1.5-19, P = .01). AKI is common in children with cerebral malaria. Hemodynamic measurements suggest increased vascular tone contributes to AKI.
期刊介绍:
Seminars in Nephrology is a timely source for the publication of new concepts and research findings relevant to the clinical practice of nephrology. Each issue is an organized compendium of practical information that serves as a lasting reference for nephrologists, internists and physicians in training.
