Since the introduction of routine assay for natriuretic peptides (NP), there is an increasing number of clinical applications for these assays. Due to the continuously increasing number of prescription of those tests, a reappraisal of the use of natriuretic peptide assays, namely BNP and NT-proBNP in France was necessary. This ...

Laurence Piéroni, Pierre Delanaye, Anne Boutten, Anne-Sophie Bargnoux, Eric Rozet, Vincent Delatour, Marie-Christine Carlier, Anne-Marie Hanser, Etienne Cavalier, Marc Froissart, Jean-Paul Cristol, ,

Chronic kidney disease definition is based on glomerular filtration rate (GFR) estimations which are derived from creatinine-based equations. The accuracy of GFR estimation is thus largely dependent of those of serum creatinine assays. International recommendations highlight the need for traceable creatinine assays. The French Society of Clinical Biochemistry conducted a ... Read more >>

[Consequences for clinical biochemists of the modifications of the creatinine-based evaluation of glomerular filtration rate between 2005 and 2008].

S Séronie-Vivien, L Pieroni, M-M Galteau, M-C Carlier, A-M Hanser, J-P Cristol, ,

Since 2005, international guidelines propose a stadification for chronic renal failure based on the glomerular filtration rate (GFR) value. The performance of the creatinine-based equations allowing the estimation of GFR and the bias of the creatinine measurements is, more than ever, a crucial issue. The consequences for the clinical biologists ... Read more >>

Hepatic injury due to traditional aqueous extracts of kava root in New Caledonia.

Stefan Russmann, Yann Barguil, Pierre Cabalion, Marina Kritsanida, Daniel Duhet, Bernhard H Lauterburg,

Traditional aqueous kava extracts were the most probable cause of hepatitis in two patients presenting with markedly elevated transaminases and hyperbilirubinaemia. A consequent survey of 27 heavy kava drinkers in New Caledonia showed elevated gamma glutamyl transferase in 23/27 and minimally elevated transaminases in 8/27. We conclude that not only ...
