  • [Show abstract] [Hide abstract] ABSTRACT: Treatment-resistant hypertension, or resistant hypertension, is defined as blood pressure that remains above target despite concurrent use of at least 3 antihypertensive agents from different classes at optimal doses, one of which should be a diuretic. Important considerations in the diagnosis of treatment-resistant hypertension include the exclusion of pseudoresistance and the evaluation of potential secondary causes of hypertension and of concomitant conditions that maintain high blood pressure. The ability to diagnose true treatment-resistant hypertension is important for selection of patients who may be appropriately treated with an invasive therapy. Currently there are three interventional approaches to treat resistant hypertension, namely: (1) reduction of the activity of the sympathetic nervous system by renal nerve ablation, (2) stimulation of baroreceptors, and (3) creation of a peripheral arterial venous anastomosis. This review focuses on the rationale behind these invasive approaches and the clinical results.

  • [Show abstract] [Hide abstract] ABSTRACT: Drug-related laboratory test interference or drug/laboratory test interactions (DLTI) is a major source of laboratory errors. DLTI is of concern with regard to both the clinical diagnosis and the monitoring of patients. Although there have been numerous reports about specific drugs that interfere with laboratory tests, there has not been a recent review on the topic. We herein provide a review of the known DLTI of U.S. FDA-approved drugs based on a systematic search of DailyMed, a website containing the labels of U.S. FDA-approved drugs. The labels for all human single-ingredient prescription drugs included in the database (1,368) were searched using stemmed keywords, and were manually reviewed for their relevance to DLTI. A total of 134 labels were positive, which indicated that the drug interferes with at least one clinical laboratory test. Antibacterial agents, psychotropic drugs, and contrast media are the classes of drugs most likely to lead to DLTI. Urine was the clinical sample most frequently affected by DLTI. The FDA drug label is a source of information for studies of DLTI, although information is still lacking for most drugs, and additional improvements are needed for many of the existing records. Medical professionals, clinicians and laboratory staff should keep these possible interactions in mind when interpreting the results of laboratory tests, and should ensure that they obtain a complete and accurate record of all drugs being used by patients in order to anticipate potential DLTI. The development of a reporting system to address potential DLTI is warranted.

  • [Show abstract] [Hide abstract] ABSTRACT: This review summarizes present evidence for the role of YKL-40 in the diagnosis, prognosis and cause of cardiovascular and alcoholic liver disease. The question of whether YKL-40 is merely a marker or a causal factor in the development of cardiovascular and liver disease is addressed, with emphasis on the Mendelian randomization design. The Mendelian randomization approach uses genetic variants associated with lifelong high plasma YKL-40 levels that are largely unconfounded and not prone to reverse causation. Thus the approach mimics a controlled double-blind randomized trial, but it uses genetic variants rather than a drug and placebo, and like a blinded trial, it allows inference about causality. Moreover, the review also covers background on the molecular biology and functions of YKL-40, YKL-40 levels in healthy individuals and reference range, and the role of YKL-40 as a biomarker of cardiovascular and alcoholic liver disease.YKL-40 is a plasma protein named after its three N-terminal amino acids, Y (tyrosine), K (lysine) and L (leucine), and its molecular weight of 40 kDa. It is produced by local inflammatory cells in inflamed tissues, such as lipid laden macrophages inside the vessel wall and perhaps also hepatic stellate cells. Observational studies show that plasma YKL-40 levels are elevated in patients with cardiovascular and liver disease and are associated with disease severity and prognosis. Furthermore, elevated plasma YKL-40 levels in apparently healthy individuals are associated with a 2-fold increased risk of future ischemic stroke and venous thromboembolism, but not with myocardial infarction, suggesting that YKL-40 could play a role in the formation of embolisms rather than atherosclerosis per se. Further, elevated YKL-40 levels combined with eexcessive alcohol consumption are associated with 10-years risk of alcoholic liver cirrhosis of up to 7%, suggesting that YKL-40 can be used as a strong non-invasive marker of predicting alcoholic liver cirrhosis.Importantly, in Mendelian randomization studies, genetically elevated plasma YKL-40 levels were not associated with risk of cardiovascular and alcoholic liver disease, thus suggesting that plasma YKL-40 does not play a causal role in the development of these diseases. Despite this, plasma YKL-40 levels may play a role in disease progression after diagnosis, and inhibition of YKL-40 activity might be a novel therapy in some cardiovascular and liver diseases.

  • [Show abstract] [Hide abstract] ABSTRACT: Therapy for hepatitis C is currently undergoing a revolution. The arrival of new antiviral agents targeting viral proteins reinforces the need for a better knowledge of the viral strains infecting each patient. Hepatitis C virus (HCV) whole genome sequencing provides essential information for precise typing, study of the viral natural history or identification of resistance-associated variants. First performed with Sanger sequencing, the arrival of next-generation sequencing (NGS) has simplified the technical process and provided more detailed data on the nature and evolution of viral quasi-species. We will review the different techniques used for HCV complete genome sequencing and their applications, both before and after the apparition of NGS. The progress brought by new and future technologies will also be discussed, as well as the remaining difficulties, largely due to the genomic variability.

  • [Show abstract] [Hide abstract] ABSTRACT: Ebola virus disease (EVD) caused by Ebola virus (EBOV), is a potent acute infectious disease with a high case-fatality rate. Etiological and serological EBOV detection methods including techniques that involve the detection of the viral genome, virus-specific antigens, and anti-virus antibodies, are standard laboratory diagnostic tests that facilitate confirmation or exclusion of EBOV infection. In addition, routine blood tests, liver and kidney function tests, electrolytes and coagulation tests, and other diagnostic examinations are important for the clinical diagnosis and treatment of EVD. Because of the viral load in body fluids and secretions from EVD patients, all body fluids are highly contagious. As a result, biosafety control measures during the collection, transport, and testing of clinical specimens obtained from individuals scheduled to undergo EBOV infection testing (including suspected, probable, and confirmed cases) are crucial. This report has been generated following extensive work experience in the China Ebola Treatment Center (ETC) in Liberia and incorporates important information pertaining to relevant diagnostic standards, clinical significance, operational procedures, safety controls, and other issues related to laboratory testing of EVD. Relevant opinions and suggestions are presented in this report to provide contextual awareness associated with the development of standards and/or guidelines related to EVD laboratory testing.

  • [Show abstract] [Hide abstract] ABSTRACT: This review explores recent innovations in four seemingly-unrelated areas of medical diagnostics, which, when used concurrently, promise to revolutionize the future of medicine. Novel microfluidics and microelectronics, combined with smart phones, allow individuals to test themselves at anytime and anywhere, thus providing instant health information. An emerging development is the availability of genomic testing directly to consumers for assessing disease predisposition. Some organizations have opened diagnostic laboratories in pharmacies and other public outlets, are encouraging consumers to test themselves, and claim that by doing so consumers will be empowered to diagnose early disease that could be effectively treated or prevented. Another recent development is the initiation of large studies that aim to better understand wellness and disease processes, through the frequent and sometimes continuous monitoring of hundreds or thousands of parameters. These are then analyzed by health coaches who advise participants on follow-up steps to correct the abnormalities and return to wellness. A number of these approaches have now entered the health market and the services can be purchased. It is highly likely that further technological innovations will contribute to the popularity of these approaches among millions of health-conscious consumers. However, the evidence for the effectiveness of these strategies to prevent or detect early disease, or to promote wellness, does not yet exist. We here analyze the perceived benefits and (neglected) harms of these approaches, in an effort to balance the optimism about their utility, until the evidence for their benefit is clearly demonstrated.

  • [Show abstract] [Hide abstract] ABSTRACT: In recent decades, the study of biological variation of laboratory analytes has received increased attention. The reasons for this interest are related to the potential practical applications of such knowledge. Biological variation data allow the derivation of important parameters for the interpretation and use of laboratory tests, such as the index of individuality for the evaluation of the utility of population reference intervals for the test interpretation, the estimate of significant change in a timed series of results of an individual, the number of specimens required to obtain an accurate estimate of the homeostatic set point of the analyte, and analytical performance specifications that assays should fulfil for their application in the clinical setting. It is, therefore, essential to experimentally derive biological variation information in an accurate and reliable way. Currently, a dated guideline for the biological variation data production and a more recent checklist to assist in the correct preparation of publications related to biological variation studies are available. Here we update and integrate, with examples, the available guideline for biological variation data production to help researchers to comply with the recommendations of the checklist for drafting manuscripts on biological variation. Particularly, we focus on the distribution of the data, an essential aspect to be considered for the derivation of biological variation data. Indeed, the difficulty in deriving reliable estimates of biological variation for those analytes, the measured concentrations of which are not normally distributed, is more and more evident.

  • [Show abstract] [Hide abstract] ABSTRACT: In laboratory medicine, the terms "standardization" and "harmonization" are frequently used interchangeably as the final goal is the same: the equivalence of measurement results among different routine measurement procedures over time and space according to defined analytical and clinical quality specifications. However, the terms define two distinct, albeit closely linked, concepts based on traceability principles. The word "standardization" is used when results for a measurement are equivalent and traceable to the International System of Units (SI) through a high-order primary reference material and/or a reference measurement procedure (RMP). "Harmonization" is generally used when results are equivalent, but neither a high-order primary reference material nor a reference measurement procedure is available. Harmonization is a fundamental aspect of quality in laboratory medicine as its ultimate goal is to improve patient outcomes through the provision of accurate and actionable laboratory information. Patients, clinicians and other healthcare professionals assume that clinical laboratory tests performed by different laboratories at different times on the same sample and specimen can be compared, and that results can be reliably and consistently interpreted. Unfortunately, this is not necessarily the case, because many laboratory test results are still highly variable and poorly standardized and harmonized. Although the initial focus was mainly on harmonizing and standardizing analytical processes and methods, the scope of harmonization now also includes all other aspects of the total testing process (TTP), such as terminology and units, report formats, reference intervals and decision limits as well as tests and test profiles, requests and criteria for interpretation. Several projects and initiatives aiming to improve standardization and harmonization in the testing process are now underway. Laboratory professionals should therefore step up their efforts to provide interchangeable and comparable laboratory information in order to ultimately assure better diagnosis and treatment in patient care.

  • [Show abstract] [Hide abstract] ABSTRACT: Abstract Cardiac diseases have been extensively studied following diabetes and altered metabolism has been implicated in its initiation. In this context, there is a shift from glucose utilization to predominantly fatty acid metabolism. We have focused on the micro- and macro-environments that the heart uses to provide fatty acids to the cardiomyocyte. Specifically, we will discuss the cross talk between endothelial cells, smooth muscles and cardiomyocytes, and their respective secretory products that allows for this shift in metabolism. These changes will then be linked to alterations in the cardiovascular system and the augmented heart disease observed during diabetes. Traditionally, the heart was only thought of as an organ that supplies oxygen and nutrients to the body through its function as a pump. However, the heart as an endocrine organ has also been suggested. Secreted products from the cardiomyocytes include the natriuretic peptides atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP). Both have been shown to have vasodilatory, diuretic and antihypertensive effects. These peptides have been extensively studied and their deficiency is considered to be a major cause for the initiation of cardiovascular and cardiometabolic disorders. Another secretory enzyme, lipoprotein lipase (LPL), has been implicated in diabetic heart disease. LPL is a triglyceride-hydrolyzing enzyme that is synthesized within the cardiomyocyte and secreted towards the lumen under various conditions. For example, moderate or short-term hyperglycemia stimulates the release of LPL from the cardiomyocytes towards the endothelial cells. This process allows LPL to contact lipoprotein triglycerides, initiating their break down, with the product of lipolysis (free fatty acids, FA) translocating towards the cardiomyocytes for energy consumption. This mechanism compensates for the lack of glucose availability following diabetes. Under prolonged, chronic conditions of hyperglycemia, there is a need to inhibit this mechanism to avoid the excess delivery of FA to the cardiomyocytes, an effect that is known to induce cardiac cell death. Thus, LPL inhibition is made possible by a FA-induced activation of PPAR β/δ, which augments angiopoietin-like 4 (Angptl4), an inhibitor of LPL activity. In the current review, we will focus on the mediators and conditions that regulate LPL and Angptl4 secretion from the cardiomyocyte, which are critical for maintaining cardiac metabolic homeostasis.

  • [Show abstract] [Hide abstract] ABSTRACT: The aim of this review article is to give an update on the state of the art of the immunoassay methods for the measurement of B-type natriuretic peptide (BNP) and its related peptides. Using chromatographic procedures, several studies reported an increasing number of circulating peptides related to BNP in human plasma of patients with heart failure. These peptides may have reduced or even no biological activity. Furthermore, other studies have suggested that, using immunoassays that are considered specific for BNP, the precursor of the peptide hormone, proBNP, constitutes a major portion of the peptide measured in plasma of patients with heart failure. Because BNP immunoassay methods show large (up to 50%) systematic differences in values, the use of identical decision values for all immunoassay methods, as suggested by the most recent international guidelines, seems unreasonable. Since proBNP significantly cross-reacts with all commercial immunoassay methods considered specific for BNP, manufacturers should test and clearly declare the degree of cross-reactivity of glycosylated and non-glycosylated proBNP in their BNP immunoassay methods. Clinicians should take into account that there are large systematic differences between methods when they compare results from different laboratories that use different BNP immunoassays. On the other hand, clinical laboratories should take part in external quality assessment (EQA) programs to evaluate the bias of their method in comparison to other BNP methods. Finally, the authors believe that the development of more specific methods for the active peptide, BNP1–32, should reduce the systematic differences between methods and result in better harmonization of results.
