Mortality prediction model from combined serial lactate, procalcitonin and calprotectin levels in critically ill patients with sepsis: A retrospective study according to Sepsis-3 definition.

Objective: 1) To evaluate the ability of baseline and on 24 h serum calprotectin, in comparison to canonical biomarkers (lactate and procalcitonin), for prognosis of 28-day mortality in critically ill septic patients; and 2) To develop a predictive model combining the three biomarkers.

Design: A single-center, retrospective study.

Setting: Intensive Care Unit of a university hospital.

Coffee Colored Serum, Adverse Reaction of Eltrombopag.

Serum index and macroscopic characteristics of samples can give valuable information and should be interpreted as a result. Following centrifugation of the sample, on gross inspection it was observed that the serum had a brown color. After ruling out the main causes that can cause a brown coloration, such as intravascular hemolysis or high concentrations of methemoglobin, it was noted that the patient was receiving a high-dose of Eltrombopag therapy.

Role of Pancreatic Stone Protein as an Early Biomarker for Risk Stratification of Acute Pancreatitis.

Background: Early risk stratification of acute pancreatitis is crucial to improve clinical outcomes. The objective of this study was to evaluate the ability of pancreatic stone protein (PSP) to predict acute pancreatitis severity and to compare it with the biomarkers and severity scores currently used for that purpose.

Patients And Methods: Prospective single-center observational study enrolling 268 adult patients with acute pancreatitis.

Increased concentrations of procalcitonin in patients with paracetamol intoxication.

Objectives: Paracetamol intoxication is one of the causes of elevated procalcitonin concentrations unrelated to infection. We report a case series of two patients intoxicated with paracetamol whose laboratory data revealed a significant elevation of serum procalcitonin concentrations without clinical, radiological and/or biological evidence of infection. The underlying mechanism by which paracetamol triggers an increase in procalcitonin concentrations is still unclear.

Influence of the matrix type over the concentration of GDF-15.

Growth differentiation factor 15 (GDF-15) has been suggested as a prognostic biomarker for bleeding and mortality in atrial fibrillation (AF). To date, serum and EDTA matrices are standardized for the GDF-15 assay but it is unclear if it can be measured also in citrate. In this study, we aim to investigate if the Elecsys GDF-15 assay (Roche Diagnostics, Mannheim, Germany) can be determined accurately in citrate samples in a cohort of 10 patients with AF and 10 healthy controls.
