Several equations have been developed for estimated glomerular filtration rate (eGFR) in patients with chronic kidney disease (CKD), but none were developed based on data from elderly kidney transplant recipients (KTR). The primary aim of this study was to evaluate different creatinine based equations in stable elderly KTR. A national cross-sectional study was performed using data from 263 consecutive kidney transplant recipients 60 years or older who performed a routine GFR measurement one year after engraftment...

BACKGROUND/AIMS: A lack of baseline serum creatinine (SCr) data leads to underestimation of the burden caused by acute kidney injury (AKI) in developing countries. The goal of this study was to investigate the effects of various baseline SCr analysis methods on the current diagnosis of AKI in hospitalized patients. METHODS: Patients with at least one SCr value during their hospital stay between January 1, 2011 and December 31, 2012 were retrospectively included in the study...

Background: Chronic kidney disease (CKD) in cirrhosis is one of the dreaded complications associated with a steep rise in mortality and morbidity, including diabetes. There are limited data on the prevalence of CKD and the association with diabetes in outpatients with cirrhosis. Methodology: This is a cross-sectional study of 7,440 adult liver cirrhosis patients enrolled from August 2001 to April 2010 in a medical center. Case control matching by age and sex with 1,967 pairs, and conditional logistic regression for odds of diabetes was analyzed using adjusted model...

Bardet-Biedl Syndrome (BBS) is a rare multi-systemic disease with autosomal recessive transmission. BBS was at first considered to be homogeneous as for its genetics, but subsequent studies have shown an extensive gene variability. Currently, 21 genes (BBS1-21) present on different chromosomes have been mapped: these genes are responsible for BBS phenotypes and they show a great heterogeneity of mutations.The most common genes are BBS1 (locus 11q13) and BBS10.We show here the case of a 50 year old patient with BBS...

PURPOSE: Evaluating gamma camera image quality is a routine task required for annual physics surveys and laboratory accreditation. A common method is visual assessment of a planar view of the American College of Radiology (ACR) phantom, for which a satisfactory result is to resolve 7.9 mm diameter cold rods with high contrast. The objective is to investigate an automated quantitative measure of planar image quality for more precise evaluation of gamma camera performance. METHODS: Planar images were automatically co-registered to a template of the phantom's cold rod pattern...

REVIEW
Laura A Hart, Gail D Anderson
International guidelines recommend the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) method to monitor kidney function in chronic kidney disease using either creatinine- or cystatin C-based estimation methods. The choice of an estimation method to determine dosage for renally eliminated drugs is not as clear. For the majority of currently marketed drugs, the Cockcroft-Gault equation with the Jaffe method, a non-isotope dilution mass spectrometry, standardized serum creatinine, was used to estimate kidney function to recommend dosing adjustment in kidney impairment...

Creatinine-based glomerular filtration rate estimation (eGFRcr) has been improved and refined since the 1970s through both the Modification of Diet in Renal Disease (MDRD) Study equation in 1999 and the CKD Epidemiology Collaboration (CKD-EPI) equation in 2009, with current clinical practice dependent primarily on eGFR for accurate assessment of GFR. However, researchers and clinicians have recognized limitations of relying on creatinine as the only filtration marker, which can lead to inaccurate GFR estimates in certain populations due to the influence of non-GFR determinants of serum or plasma creatinine...

Renal tissue hypoxia is a final pathway in the development and progression of chronic kidney disease (CKD), but whether renal oxygenation predicts renal function decline in humans has not been proven. Therefore, we performed a prospective study and measured renal tissue oxygenation by blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI) in 112 patients with CKD, 47 with hypertension without CKD, and 24 healthy control individuals. Images were analyzed with the twelve-layer concentric objects method that divided the renal parenchyma in 12 layers of equal thickness and reports the mean R2* value of each layer (a high R2* corresponds to low oxygenation), along with the change in R2* between layers called the R2* slope...

BACKGROUND: Urinary NGAL (uNGAL)-associated acute kidney injury (AKI) is common following liver transplant (LT), but whether early AKI predicts chronic kidney disease (CKD) and mortality remains uncertain. METHODS: Adults with LT from 2008-2010 in a previously published prospective cohort evaluating serial uNGAL pre- and post-LT were retrospectively assessed to evaluate uNGAL as a predictor of long-term outcomes post-LT. The primary outcomes were post-LT CKD, defined as MDRD estimated glomerular filtration rate (GFR)<60 mL/min/1...

THE MAIN PROBLEM: Acute kidney injury (AKI) is reported as a common complication of marathon and ultramarathon running. In previous studies AKI was diagnosed on the basis of the creatinine level in serum and estimated glomerular filtration rate (eGFR). In the present study we calculated eGFR and also measured creatinine clearance after every 25 km of a 100 km run. METHODS: 20 healthy, amateur runners (males, mean age 40.75 ± 7.15 years, mean weight 76.87 ± 8.39 kg) took part in a 100 km run on a track...
