Usefulness of suPAR in the risk stratification of patients with sepsis admitted to the emergency department.

To investigate the role of suPAR in patients with sepsis admitted to the Emergency Department (ED). We performed multicentre prospective trial including patients admitted to the ED of three different Italian hospitals. Patients were studied upon admission on day 1, 2, 4 and 7.

Therapeutic drug monitoring of levetiracetam: comparison of a novel immunoassay with an HPLC method.

Background: Therapeutic drug monitoring of the anticonvulsant levetiracetam may be indicated in patients with conditions that may alter pharmacokinetic characteristics, for tailoring individual dosage regimens or to investigate patient compliance. In this study, the Bio-Rad high-performance liquid chromatography (HPLC) method (in-use method) and the ARK immunoassay method (new method) for levetiracetam monitoring in serum were compared.

Methods: Levetiracetam concentrations were determined in 63 samples using: (1) "Levetiracetam by HPLC" kit by Bio-Rad (Hercules, CA) on the Agilent 1100 HPLC system, and (2) "ARK Levetiracetam" immunoassay by ARK Diagnostics Inc (Fremont, CA) on the CDx90 platform by ThermoFisher Scientific Inc.

High performance liquid chromatography evaluation of serum carbohydrate-deficient transferrin and more sialylated transferrin glycoforms in children.

Objectives: The evaluation of the age-specific distribution of transferrin glycoforms in paediatric patients may help in defining reference intervals which are critical for an improved and earlier diagnosis.

Design And Methods: Serum samples from 224 children (age: 2 months-14 years) were analyzed by HPLC (Bio-Rad CDT/HPLC kit) and glycoforms expressed as percentage of the total area of transferrin (Tf).

Results: Asialo- and Monosialo-Tf were not detectable in any patient.

Pregnancy and variations of carbohydrate-deficient transferrin levels measured by the candidate reference HPLC method.

Aims: Contrasting data are available on the diagnostic accuracy of carbohydrate-deficient transferrin (CDT) during pregnancy. These differences may depend in part on how CDT was evaluated and expressed. Here, we report on variations of CDT levels in pregnant women using the high performance liquid chromatography (HPLC) candidate reference method.
