Post-dilution high convective transport improves microinflammation and endothelial dysfunction independently of the technique.
We examined the effects of different online hemodiafiltration techniques on microinflammation and endothelial damage/repair. ⋯ An increase in convective transport improves the microinflammatory state and the endothelial damage/repair of these patients independently of the technique used.

Citrate anticoagulation in hemodialysis (HD) is increasingly drawing attention in the nephrology community. One of the major deterrents to a more widespread use are the monitoring requirements for fear of systemic calcium derangements. Means of accurately predicting systemic ionized calcium (iCa) may help to overcome this challenge. We have previously presented a mathematical model of regional citrate anticoagulation (RCA) to address this need. Here, we present a refined model and show results in an independent validation cohort of maintenance HD patients on Citrasate®, a calcium- and citrate-containing dialysate. ⋯ This study demonstrates that the novel hybrid model is an improvement over the previously published model and that it is capable of predicting end-dialysis systemic iCa levels with improved accuracy and precision even in a citrate dialysis setting which was much different from the original derivation cohort.

We hypothesized that sepsis could have an impact on the sensitivity of serum and urinary neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (CysC) for acute kidney injury (AKI) diagnosis in critically ill children. ⋯ uNGAL, sCysC and uCysC were not altered by sepsis and were good predictors of AKI. In a septic state, sNGAL alone did not discriminate patients with AKI from those without AKI.

Acute kidney injury (AKI) is a common complication in pediatric and neonatal intensive care units (ICU). Renal replacement therapy (RRT) is frequently needed in children in whom supportive therapy is not enough to satisfy their metabolic demands or to be able to provide adequate nutrition. The decision to begin dialysis should not be delayed since experience in infants shows that the shorter the time from the insult to the beginning of dialysis, the higher the survival rate. ⋯ Nonetheless, when Kt/V has been applied to acutely ill children, it has been shown that PD can provide adequate clearances for most infants. The outcomes of critically ill patients with AKI treated with PD are comparable to other dialysis modalities. Therefore, the decision about dialysis modality should be based on local expertise, resources available, and patient's clinical status.
