Comparative Study
Serum matrix Gla protein concentrations in patients with mild and severe acute pancreatitis.
Acute pancreatitis (AP) causes an increase in proinflammatory cytokine and acute phase protein levels. Our previous studies in AP showed the role of fetuin A as a negative acute phase protein. Matrix Gla protein (MGP), beside fetuin A, is one of the main inhibitors of extraosseous calcification. In the present preliminary study we evaluated the relationship between MGP, lipase, and inflammation in AP patients. ⋯ Our preliminary results indicate that the MGP level correlated negatively with all of the proinflammatory cytokines and acute phase proteins studied in patients with AP, and positively with lipase, fetuin A, and albumin measurements. These findings may indicate the role of MGP in calcium and phosphate metabolism disturbances in the course of AP.

Rapid and reliable exclusion of acute myocardial infarction during emergency department triage is an important clinical need. The purpose of this study was to evaluate the potential role of copeptin, a marker of acute endogenous stress, together with high sensitive troponin-I for a rapid and early rule-out of acute myocardial infarction. ⋯ Copeptin concentrations are more sensitive than myoglobin as an early marker of myocardial damage. Although copeptin provides significant incremental value on top of high sensitivity troponin-I, myoglobin does not.

Comparative Study Controlled Clinical Trial
Correlation between rotation thrombelastometry ROTEM analysis and standard haemostatic parameters during liver transplantation.
The determination of the correlations between simultaneously performed rotation thrombelastometry ROTEM analysis and standard haemostatic analysis during liver transplantations is indispensable for performing an adequate perioperative haemostatic monitoring. ⋯ The correlations found in the present study suggest to perform the haemoststic liver transplantation monitoring through a parallel systematic analysis of both standard and rotation thrombelastometry parameters and confirm the ROTEM method as preferable and highly informative.

Aneurysm and ectasia have similar pathological pathways. TH2-associated cytokines are stimulated by aneurismal tissue and correspondingly lack mediators associated with TH1 response. In this study, we measured serum TNF-alpha and IL-18 levels which are strong TH1 stimulating cytokines and also investigated the expression of CD11a, CD11b, CD18 adhesion molecules and CD45 on leukocytes in patients with coronary artery ectasia (CAE) and controls with normal coronary arteries (NCA). ⋯ The decreased levels of TNF-alpha may indicate predominance of TH2 and lack of TH1 type immunity in CAE patients, similar to patients with aortic aneurysms. Increased levels of cell surface adhesion molecules in CAE are an indicator of activation of leukocytes for adherence and transmigration through the vessels for the initiation of inflammation.

Procalcitonin (PCT) and C-reactive protein (CRP) measurements in pleural fluid and plasma have been proposed to facilitate differential diagnosis of pleural effusion (PE). The primary aim of this study was to evaluate the usefulness of these measurements when differentiating between benign (BPE) and malignant pleural effusion (MPE). ⋯ CRP levels in the pleural fluid and plasma were higher in patients with BPE, particulary infectious PE. However, the measurement of CRP and PCT is not a useful parameter for discriminating between BPE and MPE and does not provide useful information in clinical practice.
