Raccomandazioni ad interim di SIBioC per l’analisi sierologica dell’infezione da SARS-CoV-2
Ad interim SIBioC recommendations for serological assessment of SARS-CoV-2 infection
<p>The recent pandemic outbreak caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and associated with the pathology called COVID-19 (coronavirus disease 2019), has now become one of the most strenuous health care challenges since the emergence of the three pandemics caused by influenza viruses during the past century. Throughout the clinical decision-making of COVID-19, laboratory tests are essential for supporting the screening, diagnosis, prognostication and therapeutic monitoring of this severe infectious disease. Serological testing, that reflects the humoral immune response developing after interaction between the host and the virus (or its components), enables to garner a vast array of clinical information which can be especially used in seroprevalence or seroconversion studies. To this end, the Task Force on COVID-19 of the Italian Society of Clinical Biochemistry and Clinical Molecular Biology (SIBioC) has endorsed a series of technical, practical and clinical ad interim recommendations, aimed at facilitating and optimizing the introduction, clinical usage and governance of SARS-CoV-2 serological immunoassays in routine practice.</p>

Il “Libro Bianco” dei Giovani Professionisti di Medicina di Laboratorio in Italia: risultati dell’indagine del Gruppo di Studio SIBioC Young Scientists
The "white paper" of young Laboratory Medicine professionals in Italy: results from a survey by the SIBioC - Young Scientists Working Group
<p>Introduction: Laboratory Medicine is continuously changing because of the advent of new technologies and perspectives, such as automation, Big Data and omics sciences. Professionals&rsquo; profiles are changing concurrently, developing the new technological, clinical and management skills required nowadays. In order to assess training needs as well as education and working conditions, the SIBioC Young Scientists Working Group (YS-WG) promoted a questionnaire directed to professionals &le;40 years old.<br />Methods: the questionnaire was prepared using Survey Monkey and was sent to the 587 SIBioC members &le;40 years old; it was also diffused via the YS-WG social media pages, and through personal e-mails with the help of Specialty School Offices. The questionnaire included 54 questions examining different aspects: participation in SIBioC activities, scientific interests, working conditions, evaluations of training and education experiences, expectations for the future professional life.<br />Results: during three months, 282 responses have been collected. The most represented professionals are Biologists (PhD) (46%), followed by Medical Doctors (24%). 33% of participants has an open-ended contract, 15% temporary, 17% freelance and 17% has a scholarship/research grant; 46% of them do not receive any remuneration. Around 60% work in public institutions (Universities or Hospitals); 52% are involved in clinical area, 29% in research. Residents&rsquo; evaluation on educational quality of Specialty Schools is rather heterogeneous. Among the 193 SIBioC members, 35% is actively participating in at least one of the society&rsquo;s Working Group. Most of the participants are regular readers of the SIBioC official journal (Biochimica Clinica), consult LabTestsOnline web site, and participate to SIBioC scientific events and/or to the Society e-learning courses.<br />Conclusions: the results of the survey are a key point for the Society, allowing to understand the young laboratory professionals needs, so that they can be accompanied and encouraged in a full development of their future professional life.</p>

Valutazione precoce del danno cardiaco da farmaci chemioterapici: importanza della misura delle troponine cardiache I e T con metodi ad alta-sensibilità analitica
High-sensitivity cardiac troponin I and T methods for the early detection of myocardial injury in patients on chemotherapy
<p>Important advances achieved in pharmacological cancer treatment have led progressively to a reduction in mortality from many forms of cancer, and increasing numbers of previously incurable patients can now hope to become cancer-free. Yet, to achieve these improved outcomes a high price has been paid in terms of untoward side effects associated with treatment, cardiotoxicity in particular. Several recent studies have reported that cardiac troponin assay using high-sensitivity methods (hs-cTn) can enable the early detection of myocardial injury related to chemotherapy or abuse of drugs that are potentially cardiotoxic. Several authors have recently suggested that changes in hs-cTn values enable the early diagnosis of cardiac injury from chemotherapy, thus potentially benefitting cancer patients with increased troponin values by initiating early cardioprotective therapy. However, large randomised clinical trials are needed in order to evaluate the cost/benefit ratio of standardised protocols for the early detection of cardiotoxicity using the hs-cTn assay in patients treated with chemotherapy.</p>

Calcolo e valutazione dei valori di riferimento della troponina cardiaca I (cTnI) misurata in un gruppo di volontari sani italiani con metodi immunometrici ad alta sensibilità: uno studio multicentrico
Establishment and evaluation of cardiac troponin I reference values measured in a group of Italian healthy volunteers using high-sensitivity methods: a multi-center study.
<p>Introduction: this study compares the cardiac troponin I (cTnI) values measured with three high-sensitivity (hs) different methods in apparently healthy volunteers enrolled in a multicenter study.<br />Methods: heparinized plasma samples were collected from 1511 volunteers in 8 Italian clinical institutions (mean age 51.5 years, SD 14.2, range 18-86, female to male ratio 0.94). All volunteers denied chronic or acute diseases and had normal values of routine laboratory tests and ECG. The reference laboratory of the study (Laboratorio Fondazione CNR Regione Toscana G. Monasterio, Pisa, Italy) assayed all plasma samples with three hs-methods: Architect hs-cTnI, Access hs-cTnIand ADVIA Centaur XPT hs-cTnI. After the exclusion of outlier values, calculation of 99th percentile (Upper Reference Limit, URL) values was performed using both robust nonparametric and bias corrected and accelerated bootstrap methods.<br />Results: large between-method differences were found. ADVIA Centaur measured higher cTnI values (up to 2-fold) than the two other methods. cTnI values were significantly higher in men than in women, and progressively increased with age over 55 years. Moreover, 99th percentile URL values also depended on the statistical approach used for calculation (robust non-parametric versusbootstrap). All 99th percentile URL values calculated with non-parametric robust method were on average slightly lower than those suggested by manufacturers (mean difference 4.2 ng/L, standard error 1.7, p=0.0273).<br />Conclusion: clinicians should be advised that plasma samples from the same patient should be measured for hs-cTnI in the same laboratory. Specific clinical studies are needed to establish the most appropriate statistical approach to calculate 99th percentile URL values for hs-cTnI methods.</p>

La Medicina di Laboratorio: gli specialisti di domani
Laboratory Medicine: specialists of tomorrow
<p>Laboratory Medicine rides the wave of technological progress, the metamorphosis of information systems and data management. The Young Specialist is not a mere observer, but rather takes a leading role in this change, taking advantage of the opportunities offered by &ldquo;omics&rdquo; technologies, capturing new ideas and innovative stimuli that lead to a new concept of work and research oriented to health and prevention. Thanks to the support of international web platforms, training and exchange programs supported by the International Scientific Societies and Federations that favor professional and scientific growth, Young Scientists work in a global context. In this scenario, the SIBioC Young Scientists Study Group, with the auspices of SIBioC, EFLM and IFCC, organized a meeting on &quot;Laboratory Medicine: Specialists of tomorrow&quot; with the aim of discussing and highlighting some of the most important challenges, such as technological progress, training and internationalization of young people. Finally, the future of laboratory medicine looks at a multidisciplinary approach that leads to integrated diagnosis, identification of the frail patient, the use of the Point of Care Testing as an indispensable tool in crisis areas, making the dialogue between physician and laboratory specialist a fundamental step for the diagnosis and treatment with the final aim of a better outcome for the patient.</p>

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>

Glycated albumin is correlated to insulin resistance and β-cell secretory function in subjects at risk of developing diabetes
<p>Insulin resistance and &beta;-cell secretory function represent two main issues in the pathogenesis of type 2 diabetes mellitus (T2DM). Conflicting results have been obtained about the association between glycated albumin (GA) and body mass index (BMI), insulin resistance and &beta;-cell function in diabetic patients. Actually, the relationship (if any) between GA and the markers of glucose homeostasis and insulin resistance in subjects at risk of developing diabetes, has not been completely elucidated yet. Two hundred and one patients undergoing to oral glucose tolerance test (OGTT) were enrolled in the study. Routine laboratory tests, including fasting insulin, were performed at enrollment. GA was measured on plasma-EDTA by quantILab<sup>&reg;</sup> Glycated Albumin (Instrumentation Laboratory, A Werfen Company) on ILab Taurus analyzer. According to the plasma glucose concentration measured after 2 hours of glucose intake (2h- PG), 13 subjects (6.4%) were classified as impaired glucose tolerance (IGT). GA weakly correlated with fasting plasma glucose (FPG) (r=0.21; P=0.002), with HbA1c (r=0.16; P=0.024) but not with 2h-PG (P=0.7). GA, but not HbA1c, was negatively correlated to HOmeostasis Model Assessment for &beta; cell fuction (HOMA-&beta;) (r<sup>2</sup>=0.23; P&lt;0.001), to HOMA for insulin resistence (HOMA-IR) (r<sup>2</sup>=0.15; P&lt;0.0001) and to BMI (r<sup>2</sup>=0.05; P=0.001). In a stepwise multivariate regression analysis including HbA1c, HOMA-&beta;, plasma albumin, BMI, eGFR, age, FPG, and HOMA-IR as predictors of GA, only HbA1c (&beta;-coefficient: 0.04; P=0.038) and HOMA-&beta; (&beta;-coefficient: -0.01; P&lt;0.0001) were able to predict GA levels (r<sup>2</sup>=0.26; P&lt;0.001 for the model). Our results demonstrated that GA was associated to HOMA-&beta; and, to a lesser extent, to HOMA-IR and BMI. The increase of GA values can be explained by the reduction of &beta;-cell secretory function in subjects with no significant increase of FPG and 2h-PG.</p>

L’uso dei biomarcatori del liquido cerebrospinale nella diagnosi della malattia di Alzheimer: un’indagine tra i laboratori italiani
The clinical use of cerebrospinal fluid biomarkers for Alzheimer’s disease diagnosis: an Italian survey
<p>The use of cerebrospinal fluid (CSF) biomarkers amyloid <span style="font-family:symbol; font-size:12.0pt">b</span><sub>1-42</sub> (A<span style="font-family:symbol; font-size:12.0pt">b</span><sub>42</sub>), tau (T-tau), and phosphorylated tau (p-tau<sub>181</sub>) for the diagnosis of Alzheimer&rsquo;s Disease is limited to a restricted number of neurological centers. By a survey, we aimed to do a &ldquo;selfie&rdquo; of the use and diffusion of CSF biomarkers of dementia in Italy, the standardization of pre-analytical procedures, the harmonization of ranges, and the participation to Quality Control programs. The members of SIBioC and of the Piattaforma Italiana per le Malattie Neurodegenerative della Societ&agrave; Italiana di Neurologia per le Demenze (SINdem-ITALPLANED) together with other neurological clinics all over Italy have received an online questionnaire. Forty neurological centers require CSF analyses while 7/20 regions (35%) lack CSF laboratories. Standardization of pre-analytical procedures is present in 62.02% of laboratories and only 56% participate to International Quality Control Programs. There is no harmonization of the reported cut-offs. A cost-benefit analysis, with a program for standardization and harmonization should be promoted by Scientific Societies and National Health Services.</p>

Esami di laboratorio in Pronto Soccorso: una proposta di consenso SIBioC - Medicina di Laboratorio e Academy of Emergency Medicine and Care
Laboratory tests in the Emergency Department: a consensus document by SIBioC-Medicina di Laboratorio and the Academy of Emergency Medicine and Care
<p>Laboratory diagnostics in the emergency setting encompasses the identification of appropriate testing according to specific acute conditions. Since the pathway of ordering tests in the Italian Emergency Departments (EDs) is rather heterogeneous, SIBioC-Medicina di Laboratorio and the Academy of Emergency Medicine and Care designed a survey aimed to generate consensus pertaining to appropriate laboratory tests in most frequent acute conditions. A questionnaire including a panel of laboratory tests was administered to 8 representative members of each of the two societies, who were asked to provide a score between 1 and 3 for the various tests, where a score of 1 entailed &ldquo;highly recommended&rdquo;, 2 &ldquo;recommended in specific conditions&rdquo; and 3 identified &ldquo;highly discouraged&rdquo; tests. The results of the questionnaire are shown as mean (&plusmn;SD) of individual responses, thus allowing to define a scale of priority comprised between &ldquo;highly recommended&rdquo; and &ldquo;highly discouraged&rdquo;. Overall, 24 tests were classified as &ldquo;highly recommended&rdquo;, whereas 6 were &ldquo;highly discouraged&rdquo;. The remaining 16 tests were classified as &ldquo;somehow recommended&rdquo; or &ldquo;somehow discouraged&rdquo;. In the expectations of the two societies, this document may represent a first step towards harmonizing the laboratory test ordering in Italian EDs.</p>

Ferritina e siderofagi liquorali nella diagnosi di siderosi cerebrale superficiale
Cerebrospinal fluid ferritin and siderophages in the diagnosis of superficial cerebral siderosis
<p>We observed&nbsp;a case of superficial siderosis (SS) of the central nervous system caused by an hemorrhagic trauma forty years&nbsp;before. We questioned whether SS was the stabilized effect of a remote bleeding or an evolutionary process&nbsp;indirectly related to the trauma. Moreover, we aimed to evaluate whether an iron chelator can affect the level of iron&nbsp;deposition. Magnetic Resonance (MRI) demonstrated iron accumulation mainly on the surface of the cerebellum and&nbsp;brain stem. Cerebrospinal fluid (CSF) microscopic analysis revealed few siderophages; CSF ferritin level was 76&nbsp;ng/mL (reference value &lt;12). After treatment with an iron chelator (deferiprone) for three months, MRI was&nbsp;unchanged, but the CSF ferritin was about 20% less. The presence of few siderophages supported the hypothesis of&nbsp;a persistent subarachnoid microbleeding. CSF ferritin, as an iron deposition index, allowed a diagnosis of SS and a<br />more sensitive evaluation of the efficacy of the treatment than the MRI.</p>

Monitoring and improvement of intralaboratory turnaround time at the university hospital Campus Bio-Medico in Rome
<p>The aim of the present study was to evaluate the intralaboratory turnaround time (TAT) of the emergency samples at&nbsp;the laboratory of the university hospital Campus Bio-Medico. TAT for urgent tests was recorded during 7 months after&nbsp;the introduction of a system allowing TAT monitoring in real-time, from January to July 2012. TAT analysis was&nbsp;performed through five consecutive phases. At the end of each phase, TAT was evaluated and a corrective strategy,&nbsp;if needed, was introduced. The TAT evaluation at the end of phase I (January-March 2012) showed that all urgent&nbsp;tests were in extra-time. From the phase II (April 2012) to the phase IV (June 2012), three different consecutive&nbsp;corrective strategies, related to preanalytical and analytical phases were implemented. Each corrective action&nbsp;determined TAT improvement. In the last phase of the study (July 2012), no further corrective strategies were added,&nbsp;but a pure observation activity was decided to give time to the laboratory staff to adapt to changes introduced before.&nbsp;The intralaboratory TAT can improve through the introduction of TAT monitoring systems, gradual and step-by-step&nbsp;changes in sample management and staff adhesion to and awareness of the project.</p>
