Background: Parathyroid carcinoma (PCa) is a rare disease that can be difficult to differentiate initially from severe benign parathyroid adenoma. PCa oversecrete the amino form of PTH, which is recognized by third-generation but not by second-generation PTH immunoassays. In normal individuals, the third-generation to second-generation PTH ratio should be less than 1. Objective: Our objective was to study the utility of the third-generation to second-generation PTH ratio as a means of distinguishing PCa patients (n = 24) from control groups with and without disorders of calcium secretion, including patients on renal hemodialysis (n = 74), postrenal transplantation (n = 60), and primary hyperparathyroidism (PHP; n = 30). Setting and Design: We conducted a retrospective, laboratory-based study at tertiary referral academic centers. Results: The mean third-generation to second-generation ratio was 0.58 ± 0.10 in the dialysis patients, 0.54 ± 0.10 in the renal transplant group, 0.54 ± 0.12 in the elderly healthy patients, and 0.68 ± 0.11 in the PHP group. All 245 of these patients presented a PTH third-generation to second-generation ratio of less than 1. In contrast, we observed an inverted third-generation to second-generation PTH ratio of more than one in 20 PCa patients, whereas only four PCa patients had a normal ratio of less than 1. Conclusions: An inverted third-generation to second-generation PTH ratio occurred in the majority of patients with advanced PCa and was absent in all 245 relevant controls. A third-generation to second-generation PTH ratio higher than 1 had a sensitivity of 83.3% and a specificity of 100% among PHP patients as a marker for PCa. This ratio may be useful to identify patients with PCa earlier and to detect patients either at risk of developing PCa or those in whom recurrence is taking place. [less ▲]

Background: Prevalence of stage 3 chronic kidney disease (CKD) is increasing according to the NHANES study. Prevalence has been calculated using the MDRD study equation for estimating glomerular filtration rate (GFR). Recently, a new estimator based on creatinine, the CKD-EPI equation, has been proposed which is presumed to better perform in normal GFR ranges. The aim of the study was to measure the difference in prevalence of stage 3 CKD in a population using either the MDRD or the CKD-EPI study equations. Methods: CKDscreening is organized in the Province of Liège, Belgium. On a voluntary basis, people aged between 45 and 75 years are invited to be screened. GFR is estimated by the MDRD study equation and by the "new" CKD-EPI equations. Results: The population screened consisted in 1992 people (47% of men). Mean serum creatinine was 0.86 ± 0.20 mg/dl. The prevalence of stage 3 CKD in this population using the MDRD or the CKD-EPI equations was 11.04 and 7.98%, respectively. The prevalence of stage 3 CKD is significantly higher with the MDRD study equation (p <0,0012). Conclusions: Prevalence of stage 3 CKDvaries strongly following the method used for estimating GFR, MDRD or CKDEPI study equations. Such discrepancies are of importance and must be confirmed and explained by additional studies using GFR measured with a reference method. [less ▲]

Serum creatinine is certainly one of the most prescribed biological parameters. In this review article, we remind some historical data regarding creatinine. Different methodologies to measure creatinine in blood and urine are deeply described. We also discuss the physiological reason for its use as a glomerular filtration rate marker. However, analytical and physiological limitations are described and discussed. Creatinine clearance usefulness is finally largely discussed. [less ▲]

Introduction: Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as a promising marker for the detection of acute kidney injury. This marker has been proposed for urinary measurement. However, in the literature, authors indistinctly use "absolute" value or NGAL to creatinine ratio. Up to now, there are no strong arguments favouring for one. This question is of importance as this marker is sensed to be used only on urine random samples. To find an answer to this very practical matter, one approach could be to compare biological CV(intra-individual variation) of the "absolute" and ratio results. [less ▲]
