From age 30 onwards, kidney function physiologically decreases although this deterioration cannot yet be called chronic kidney disease. The latter appears in those exposed to cardiovascular risk factors associated with inflammation and oxidative stress. A diffuse atherosclerosis then develops Patients with a decreased glomerular filtration rate, especially below the threshold of 45 ml/min, are characterised by a poor physical heath and by cognitive disorders, leading to frailty. In these conditions, a management strategy to reduce the increased risk of acute kidney injury should be outlined and the need for renal replacement therapy be considered. One must try to maintain the best possible quality of life, promoting in some situations a conservative approach. [less ▲]

Assessing bone turnover is a key diagnostic tool in the global management of chronic kidney disease-mineral and bone disorder (CKD-MBD). Since bone biopsy is invasive and cannot be repeated in clinical practice and because bone histomorphometry is less available due to the lack of specialized laboratories, we will focus on potential biomarkers used to assess and monitor bone turnover. After briefly reviewing the pathophysiology of bone turnover in CKD and haemodialysis patients, we will focus on the strengths and limitations of the now recommended biomarkers, i.e. parathormone and bone-specific alkaline phosphatase. We will consider the clinical and also the biological aspects of the topic and also insist on the use of these biomarkers for the monitoring, and the follow-up of the turnover in haemodialysis subjects. Finally, we will discuss some of the most promising, but still not recommended, emerging biomarkers. [less ▲]

Background: Parathyroid carcinoma (PCa) is rare and often difficult to differentiate initially from benign disease. Because PCa oversecretes amino PTH that is detected by third-generation but not by second-generation PTH assays, the normal generation PTH ( 1) is inverted in PCa (ie, 1). Objective: The objective of the investigation was to study the utility and advantages of automated generation PTH ratio measurements using the Liaison XL platform over existing manual techniques. Setting: The study was conducted at a tertiary-referral academic center. Design: This was a retrospective laboratory study. Subjects: Eleven patients with advanced PCa (mean age 56.0 y). The controls were patients with 1°-hyperparathyroidism (n 144;meanage 53.8 y), renal transplantation (n 41;meanage 50.6 y), hemodialysis (n 80; mean age 65.2 y), and healthy elderly subjects (n 40; mean age 72.6 y). Results: The median (interquartile range) generation PTH ratio was 1.16 (1.10 –1.38) in the PCa group, which was significantly higher than the control groups: 0.74 (hemodialysis, 0.71–0.75), 0.77 (renal transplant, 0.73–0.79), 0.80 (healthy elderly, 0.74–0.83), and 0.76 (1°-hyperparathyroidism, 0.74–0.78). An inverted -generation PTH ratio ( 1) was seen in 9 of 11 PCa patients (81.8%) and in 7 of 305 controls (2.3%), 3 of 80 hemodialysis (3.8%), and 4 of 144 1°-hyperparathyroidism patients (2.8%). Of four PCa patients who had a normal PTH ratio with the manual method, two had an inverted -generation PTH ratio with the automated method. Conclusions: Study of the -generation PTH ratio in large patient populations should be feasible using a mainstream automated platform like the Liaison XL. The current study confirms the utility of the inverted -generation PTH ratio as a marker of PCa (sensitivity: 81.8%; specificity: 97.3%). [less ▲]

The National Kidney Disease Education Program group demonstrated that MDRD equation is sensitive to creatinine measurement error, particularly at higher glomerular filtration rates. Thus, MDRD-based eGFR above 60 mL/min/1.73 m2 should not be reported numerically. However, little is known about the impact of analytical error on CKD-EPI-based estimates. This study aimed at assessing the impact of analytical characteristics (bias and imprecision) of 12 enzymatic and 4 compensated Jaffe previously characterized creatinine assays on MDRD and CKD-EPI eGFR. In a simulation study, the impact of analytical error was assessed on a hospital population of 24 084 patients. Ability using each assay to correctly classify patients according to chronic kidney disease (CKD) stages was evaluated. For eGFR between 60 and 90 mL/min/1.73 m2, both equations were sensitive to analytical error. Compensated Jaffe assays displayed high bias in this range and led to poorer sensitivity/specificity for classification according to CKD stages than enzymatic assays. As compared to MDRD equation, CKD-EPI equation decreases impact of analytical error in creatinine measurement above 90 mL/min/1.73 m2. Compensated Jaffe creatinine assays lead to important errors in eGFR and should be avoided. Accurate enzymatic assays allow estimation of eGFR until 90 mL/min/1.73 m2 with MDRD and 120 mL/min/1.73 m2 with CKD-EPI equation. [less ▲]
