Abstract

Summary: Introduction: The analysis of the core biomarkers of Alzheimer's Disease (AD) in the cerebrospinal fluid (CSF) is recommended in the clinical units where it is available. Because of the absence of universal validated values, the determination of specific cut-off points for each center and its population is recommended. The main objective of the CORCOBIA study was to determine the cut-off points of core AD CSF biomarkers for several centers (Parc de Salut Mar, Barcelona and Hospital General de Granollers), which work with the same reference laboratory (Laboratori de Referència de Catalunya). Methods: prospective study including cognitively healthy subjects (HC, n=42), subjects with amnestic mild cognitive impairment (aMCI, n=35) and patients with dementia due to Alzheimer's Disease (AD, n=48), in whom clinical and neuropsychological assessment, neuroimaging, APOE genotyping and lumbar puncture to analyze amyloid beta peptides (Aβ42, Aβ40), total tau (tTau) and phosphorylated Tau (pTau181) using the Lumipulse G600II (Fujirebio) was performed. The values of Sensitivity (Se), Specificity (Sp), predictive values and area under the curve (AUC) were calculated, determining the cut-off point according to the Youden index by comparing the groups of HC and AD. Results: the resulting cut-offs and their AUC were the following: Aβ42 750pg/ml (AUC 0.809); Aβ42/Aβ40 0.062 (AUC 0.78); pTau181 69.85pg/ml (AUC 0.81); tTau 522.0 pg/ml (AUC 0.79); Aβ42/tTau 1.76 (AUC 0.86); Aβ42/pTau181 10.25 (AUC 0.86). Conclusions: the determination of cut-off points of core AD CSF biomarkers for the participating centers allows a better diagnostic accuracy. The ratio CSF Aβ42/pTau181 shows the highest AUC and better balance between sensitivity and specificity.

19. Sensitive sequential-injection system for the determination of 2-phenylbenzimidazole-5-sulphonic acid in human urine samples using on-line solid-phase extraction coupled with fluorimetric detection

Abstract

2-Phenylbenzimidazole-5-sulphonic acid (PBS) is an UV-filter contained in many cosmetics as a sunscreen. A direct, selective and sensitive method to determine traces of PBS is presented. The on-line separation of this compound from urine matrix was directly coupled with fluorimetric detection in a sequential-injection system. The separation was performed using a SAX microcolumn in which the analyte was retained and eluted selectively. The determination is carried out without any derivatization reaction, by directly measuring the intrinsic fluorescence of the analyte. The wavelengths of excitation and emission were 301 and 681 nm, respectively. On-line standard addition calibration is performed into the system, and only one standard solution is required. The limit of detection was 12 ng ml−1. The method was satisfactorily used to determine PBS in both, spiked and unspiked human urine samples, without any pretreatment. The relative standard deviations of the results were in the order of 2–13%. The concentrations of the analyte obtained for unspiked samples taken from sunscreen users were higher than the limit of detection. [Copyright &y& Elsevier]
