Abstract
Background: Acute kidney injury (AKI) is one of the major complications of Plasmodium falciparum malaria, especially among non-immune adults. It has recently been revealed that activation of transcription factor nuclear factor kappa B (NF-κB) induces pro-inflammatory gene expression involved in the development of progressive renal inflammatory diseases. The aim of this study was to determine whether urinary sediment NF-κB p65 can act as a biomarker for AKI in patients with P. falciparum malaria. Methods. Urinary sediments from malaria patients, including Plasmodium vivax malaria, uncomplicated P. falciparum malaria, complicated P. falciparum malaria without AKI (serum creatinine-Cr <3 mg/dl) and complicated P. falciparum malaria with AKI (Cr ≥3 mg/dl) were used to determine NF-κB p65 level by sandwich enzyme-linked immunosorbent assay (ELISA). Urinary sediments obtained from healthy controls were used as a normal baseline. Correlations between levels of urinary sediment NF-κB p65 and pertinent clinical data were analysed. Results: Urinary sediment NF-κB p65 levels were significantly increased on the day of admission (day 0) and on day 7 post-treatment in complicated P. falciparum malaria patients with AKI, compared with those without AKI (p = 0.001, p <0.001, respectively), P. vivax patients (all p <0.001) and healthy controls (all p <0.001). NF-κB p65 levels in urinary sediment cells showed a significant positive correlation with serum Cr (Day 0: rs= 0.792; p <0.001, Day 7: rs= 0.605; p <0.001) and blood urea nitrogen (BUN) (Day 0: rs= 0.839; p <0.001, Day 7: rs= 0.596; p <0.001). Conclusions: Urinary sediment NF-κB p65 level is a useful indicator for estimating renal tubular epithelial cell damage and subsequent development of AKI among patients with P. falciparum malaria. © 2014 Punsawad and Viriyavejakul; licensee BioMed Central Ltd.
