Siero o plasma? Un quesito non nuovo che attende risposte nuove
Serum or plasma? An old question awaiting for new answers.
<p>There is a continual debate on what type of sample a clinical laboratory should use. While serum is still considered the gold standard and remains the required sample matrix for some assays, laboratories must consider turn-around time, which is an important metric for laboratory performance and, more importantly, plays a critical role in patient care. In addition, a body of evidence emphasize the choice of plasma samples in order to prevent modifications of some measurands due to the coagulation process and related interferences. Advantages and disadvantages of serum and plasma are discussed on the basis of current literature and evidence. In addition, data are provided on the current utilization of the matrix (serum or plasma) in Italy and in other Countries. Finally, a rational for a possible shift from serum to plasma is provided.</p>

Shaping the epigenetic basis of Werner Syndrome
<p>Werner syndrome is an autosomal recessive genetic disease responsible for a progeroid disorder including a plethora of premature clinical signs traditionally associated with physiological ageing. The molecular alterations that lead to all phenotypes associated the disease remain still unidentified. Here we describe our recent findings and results from literature about the possibility that epigenetic changes could be associated with Werner syndrome phenotype. Recent literature evidences that epigenetic mechanisms are at the basis of both physiological and pathological processes, like insulin production and secretion. Analysis of genome-wide DNA methylation profile in the whole blood from patients affected by Werner syndrome demonstrated enrichment of hypermethylated probes in glycosphingolipid biosynthesis, FoxO signalling and insulin signalling pathways, while hypomethylated probes were enriched in PI3KAkt signalling and focal adhesion pathways. Twenty-two differentially methylated genes belonging to the enriched pathways resulted differentially expressed in Werner syndrome fibroblasts. DNA methylation profiles analysis in Werner syndrome patients revealed differentially methylated regions in genes involved in other ageing phenotypes or associated syndromes like systemic sclerosis, dyskeratosis congenita and Down syndrome. Genome-wide epigenetics changes observed in the peripheral blood from patients with Werner syndrome provide new insight in the pathogenesis of the disease, highlighting in some cases a functional correlation of gene expression and methylation status</p>

Interferenza analitica sul conteggio dei leucociti
Analytical interference on leucocyte count
<p>Chronic lymphoproliferative disorders typically affect elderly patients with a median age at the diagnosis of 71 years. These disorders include a number of conditions characterized by an abnormal proliferation of lymphocytes towards a monoclonal lymphocytosis. The case of an 83-year-old man affected by chronic lymphocytic leukemia is presented; the peripheral blood cells count, performed on the analyzer Sysmex XN-20, showed significant differences between the white nucleated red (WNR) and white differentiation (WDF) channels that did not allow the differential counting of leukocytes. On the opposite, the reflex analysis channel white progenitor cell (WPC), returned the correct white blood cell count. Actually, when the peripheral blood sample was diluted (1:5) and resubmitted to analysis, leukocytes count resulting from WNR and WDF analysis channels corresponded to that obtained in the reflex WPC analysis channel on the undiluted sample. To verify if the instrumental anomaly found in the cell counting could be associated to an elevated plasma concentrations of immunoglobulins, a serum protein electrophoresis was performed, showing the presence of four monoclonal components. These data demonstrate that the WPC channel is an important tool for the clinical laboratory, since it is able to give a correct result even when interferents are present.</p>
