Background: The utility of serum cystatin C (SCysC) as a filtration marker in kidney transplantation is uncertain. We took advantage of the recent validation of a reference calibrator for SCysC and of newly developed CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equations (2012) expressed for use with standardized SCysC level to reassess the performance of SCysC as a filtration marker in kidney transplant recipients. Study Design: Study of diagnostic test accuracy. Setting & Participants: 670 kidney transplant recipients from 3 centers undergoing glomerular filtration rate (GFR) measurements from December 2006 to November 2012. Index Test: Estimated GFR (eGFR) using the 2012 SCysC-based and serum creatinine (SCr)/SCysCbased CKD-EPI equations (eGFRcys and eGFRcr-cys, respectively) and the 2009 SCr-based CKD-EPI equation (eGFRcr), with SCysC and SCr measured at a single laboratory between April 2011 and June 2011. Reference Test: Measured GFR (mGFR) using urinary clearance of inulin. Results: Bias (the difference between mGFR and eGFR) was significantly smaller for eGFRcys and eGFRcr-cys versus eGFRcr ( 2.82 and 0.54 vs 4.4 mL/min/1.73 m2, respectively; P 0.001). Precision (standard deviation of the mean bias) also was better for eGFRcys and eGFRcr-cys versus eGFRcr (12 and 11 vs 13 mL/min/1.73 m2 [P 0.001 for both comparisons]). Accuracy (percentage of GFR estimates within 30% of mGFR) was greater for eGFRcys and eGFRcr-cys versus eGFRcr (81% and 86% vs 75%, respectively [P 0.004 and P 0.001]). Net reclassification index with respect to mGFR of 30 mL/min/1.73 m2 for eGFRcr-cys and eGFRcys versus eGFRcr was 18.8% [95% CI, 8.6%-28.9%] and 22.5% [95% CI, 10.2%-34.9%]. Limitations: Patients were exclusively of European descent; association with transplant outcome was not evaluated. Conclusions: Our data validate the use of both the newly developed SCysC-based and SCr/SCysC-based CKD-EPI equations (2012) in kidney transplant recipients. Both equations perform better than the SCr-based CKD-EPI equation (2009). [less ▲]

Among the different potential mechanisms that could lead to brain edema and intracranial hypertension in fulminant hepatic failure (FHF), the inflammatory hypothesis implies that systemic inflammation might be in part responsible for an increase in cerebral blood flow (CBF) and brain water content. In this study, the authors used a validated ischemic FHF swine model to evaluate the effects of 80 kDa large-pore membrane hemofiltration (LPHF) on intracranial pressure (ICP) and CBF, in relation with the clearance of proinflammatory cytokines and blood liver tests, as primary end points. Fifteen pigs were randomized into one of three groups: SHAM, FHF, and FHF + LPHF. All experiments lasted 6 h. In the FHF groups, liver failure was induced by liver ischemia. After 2 h, the FHF + LPHF group underwent 4 h of a zero-balance continuous veno-venous hemofiltration using a 0.7-m(2) , large-pore (78 A) membrane with a cutoff of 80 kDa. ICP, CBF, mean arterial pressure, central venous pressure, and heart rate were continuously monitored and recorded. Arterial aspartate aminotransferase, total bilirubin, creatinine, international normalized ratio, glucose, lactate and serum cytokines interleukin (IL)-6, IL-10, and tumor necrosis factor-alpha were measured at T0, T120, and T360. Over the 6 h following liver ischemia, the FHF group developed a significant increase in ICP. This ICP rise was not observed in the SHAM group and was attenuated in the FHF + LDHF group. However, the ICP levels were not different at T360 in the FHF + LDHF group compared to the FHF group. No significant effect of LPHF on liver tests or levels of proinflammatory cytokines could be demonstrated. In this model, 80 kDa LPHF was not efficient to control FHF intracranial hypertension and to decrease serum cytokine levels. [less ▲]

BACKGROUND: The recent evaluation of the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation for estimating the glomerular filtration rate (GFR) in multiple ethnicities has raised the question on how well this equation performs for African-American and Asian subjects. There is no doubt that serum creatinine (Scr) concentration differs between ethnicities and sexes. We show that creatinine-based equations for white populations may be inaccurate for estimating GFR in other ethnic/gender groups, especially in populations from Asia. METHODS: This study presents a mathematical analysis of the CKD-EPI-equation complemented with a literature review of median and reference values for IDMS-standardized Scr-concentrations for multiple ethnicities. RESULTS: The study shows that at equal eGFR-CKD-EPI-values, the ratio of Scr between females and males equals 0.79 and between other ethnicities/sexes and white males is constant too. From this information, it is possible to calculate mean Scr-values that correspond very well with literature values directly obtained from Scr-distributions in healthy white males and females and in black males, but the discrepancy is larger for other populations. CONCLUSIONS: Our results confirm the criticism that has been raised for using the CKD-EPI-equation for these ethnicities. An alternative eGFR-model is proposed based on a population-normalized Scr that needs further validation. [less ▲]
