The aim of our work was to provide comprehensive data to the study of the Parathyroid hormone (Parathormone, or PTH). In the first part of the manuscript, we studied the “laboratory” aspects of PTH determination. We thus studied the stability of the peptide when stored at different temperatures (pre-analytical phase). From an analytical point of view, we compared different methods for PTH determination and the impact of any change in PTH determination on the follow-up of the hemodialyzed patients. We also studied some analytical interferences and provided a validation strategy that takes into consideration these interferences. Finally, for the post-analytical phase, we established the reference range of PTH with two different methods. We provided guidelines on the way to establish this reference range and studied the clinical impact of applying these reference ranges in the daily routine. The second part of the manuscript is more dedicated to the “clinical” aspects of PTH determination. We thus focused on the problems encountered when determining PTH in CKD and hemodialyzed patients. We also studied different bone markers in these patients to see if one of them could, in the future, replace PTH for the follow-up of these patients. Finally, we studied the “amino-PTH”, a newly discovered form of PTH, in a large population of patients suffering from parathyroid cancer. We thus presented the PTH ratio as a potential marker of parathyroid carcinoma. [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 ▲]
