[more ▼] L’insuffisance rénale voit son incidence augmenter. Un diagnostic précoce et précis est requis. Le diagnostic de l’insuffisance rénale repose sur la mesure du débit de filtration glomérulaire. Les formules basées sur la créatinine pour déterminer ce débit ont, par rapport à la créatinine sérique seule, apporté un plus mais, dans certaines situations, elles fournissent des résultats erronés. Le recours à la mesure de la clairance de créatinine sur une récolte d’urines de 24 heures peut être, dans ces situations où les caractéristiques anthropométriques sont hors normes, utile, mais avec toujours la difficulté d’une récolte minutée correcte. Si une mesure précise du débit de filtration glomérulaire est absolument nécessaire, une méthode de référence doit être choisie telle celle au chrome EDTA ou à l’iohexol. Enfin, tout bilan néphrologique doit, outre le dosage de créatinine, comprendre au moins une analyse d’urine à la tigette. Toute positivité pour la protéinurie lors de ce test mérite de réaliser un dosage quantitatif de la protéinurie soit sur 24 heures, soit plus aisément sur un échantillon [less ▲] Detailed reference viewed: 105 (19 ULg) Microarrays for allergyGadisseur, Romy ; Cavalier, Etienne ![]() Conference (2009, January 30) Detailed reference viewed: 18 (0 ULg) Vitamine D : actualités sur les dosages - effets phosphocalciques et non phosphocalciquesCavalier, Etienne ![]() Conference (2009, January 15) Detailed reference viewed: 3 (0 ULg) La vitamine D : effets « classiques », « non classiques » et évaluation du statut du patientCavalier, Etienne ; in Médecine Nucléaire : Imagerie Fonctionnelle et Métabolique (2009), 33 Detailed reference viewed: 59 (7 ULg) Allergie au venin d'hyménoptère et tests de laboratoires : de nouvelles approches pour la prise en charge des patients à haut risque de réaction sévèreGadisseur, Romy ; Cataldo, Didier ; Collard, Laurence et alin Revue Médicale de Liège (2009), 64(11), 570-5 The consequences of Hymenoptera venom anaphylaxis are very severe but it is not obvious to predict which reactions will occur in one single patient when he is stung for the second time.

[more ▼] The consequences of Hymenoptera venom anaphylaxis are very severe but it is not obvious to predict which reactions will occur in one single patient when he is stung for the second time. For a couple of years, many new laboratory tests have been experimented and many studies published. CAST, BAT, WB, tryptase, sIgE and sIgG4 are the new valuable additional diagnostic tools that can help the decision to perform an immunotherapy or to discontinue this therapy after 3 years. The aim of our study was to determine which could be the profile of a desensitized patient and to screen for good candidates for venom immunotherapy.

[more ▼] Background: Patients with anorexia nervosa (AN) are at high risk of renal failure. Glomerular filtration rate (GFR) is overestimated when estimated by the creatinine-based equations. We have studied the accuracy and precision of cystatin C-based equations. Method: 27 AN patients were included. GFR was measured with the chromium-51-ethylenediaminetetraacetate (51Cr-EDTA) method. We have compared the accuracy and precision of creatinine-based equations (MDRD and Cockcroft) with those of different new cystatin C-based equations. Results: The creatinine-based equations overestimate measured GFR, especially the MDRD study equation. All the cystatin C-based equations also overestimate measured GFR. The Cockcroft and Gault formula and the cystatin C-based equation published by Rule have the best accuracy and precision, but these last performances remain unsatisfactory. Conclusion: Both creatinine and cystatin C-based equations strongly overestimate measured in patients with AN.

[more ▼] Background . The prevalence of stage 3 chronic kidney disease (CKD) is increasing, calculated using the modification of diet in renal disease (MDRD) study equation for estimating glomerular filtration rate (GFR). Cystatin C-based equations are also being used to estimate GFR. Using creatinine-based and cystatin C-based equations, the aim of our study was to measure the difference in prevalence of stage 3 CKD in a population. Methods . CKD screening is organized in the Province of Liege, Belgium. On a voluntary basis, people aged between 45 and 75 years are invited for screening. GFR is estimated using the MDRD study equation and by the three recent cystatin C-based equations proposed by Levey's group. The Levey 1 equation is based on cystatin C only and the Levey 2 equation on cystatin C corrected for age and sex. The Levey 3 equation combines cystatin C, creatinine, age and sex. Results . The population screened comprised 754 people. Cystatin C is highly correlated with creatinine (r = 0.6196, p<0.0001). Prevalence of stage 3 CKD when GFR is estimated by the MDRD equation study is 17.2 %, which is significantly and much higher than the prevalence obtained when cystatin C-based equations are used. Indeed, prevalence is 2 %, 3.3 % and 5.8 % with the Levey 1, 2 and 3 equations, respectively. Conclusions . The prevalence of stage 3 CKD varies strongly following the method used for estimating GFR, creatinine-based or cystatin C-based equations. Such discrepancies must be confirmed and explained in additional studies using GFR measured with a reference method.
