  • Clinical implications of fetuin-A
    • Abstract: Publication date: Available online 8 February 2019Source: Advances in Clinical ChemistryAuthor(s): Peter Jirak, Lars Stechemesser, Elena Moré, Michael Franzen, Albert Topf, Moritz Mirna, Vera Paar, Rudin Pistulli, Daniel Kretzschmar, Bernhard Wernly, Uta C. Hoppe, Michael Lichtenauer, Hermann Salmhofer Fetuin-A, also termed alpha2-Heremans-Schmid glycoprotein, is a 46 kDa hepatocyte derived protein (hepatokine) and serves multifaceted functions.(i)It acts as systemic inhibitor of extraosseous calcification, serves as transport protein for calcium and phosphate in colloidal calciprotein particles and is involved in bone mineralization. Severe derangements of this system occur in chronic renal disease and are associated with mineral bone disorder. Fetuin-A levels have been associated with survival of renal and transplant patients. Low fetuin-A and high calcification propensity each increase mortality.(ii)An independent second aspect of fetuin-A is its interaction with the insulin receptor. Associations of fetuin-A levels with metabolic syndrome as well as pursuant atherosclerotic vascular effects have been established. This could be explained by differences in patient characteristics, different stages of vascular calcifications, presence of diabetes and kidney dysfunction.(iii)A further issue is the acute phase response of fetuin-A to various inflammatory stimuli and injuries. Dependent on the mode of stimulation, fetuin-A may work as a positive or negative acute phase protein. It may also serve as a protective agent in severe systemic inflammation. A suggestive role of fetuin-A may evolve in wasting and malnutrition–inflammation–atherosclerosis syndromes of chronic disease. A novel aspect is the putative role of fetuin-A in adipose tissue inflammation.(iv)With respect to heart disease, aspects of coronary arterial disease, heart failure and valvular stenosis and calcification have been elucidated. Associations of fetuin-A levels have been found with coronary artery disease, ischemic cardiomyopathy and aortic stenosis.
       
  • Implementing circulating tumor DNA analysis in a clinical laboratory: A
           user manual
    • Abstract: Publication date: Available online 28 January 2019Source: Advances in Clinical ChemistryAuthor(s): Thibaud Koessler, Alfredo Addeo, Thierry Nouspikel Liquid biopsy, the analysis of cell-free circulating tumor DNA (ctDNA), is becoming one of the most promising tools in oncology. It has already shown its usefulness in selecting and modulating therapy via remote analysis of the tumor genome and holds important promises in cancer therapy and management, such as assessing the success of key therapeutic steps, monitoring residual disease, early detection of relapses, and establishing prognosis. Yet, ctDNA analysis is technically challenging and its implementation in the laboratory raises multiple strategic and practical issues. As for oncology clinics, integration of this novel test in well-established therapeutic protocols can also pose numerous questions. The current review is intended as a field guide for (1) diagnostic laboratories wishing to implement, validate and possibly accredit ctDNA testing and (2) clinical oncologists interested in integrating the various applications of liquid biopsies in their daily practice. We provide advice and practical recommendations based on our own experience with the technical validations of these methods and on a review of the current literature, with a focus toward gastro-intestinal, lung and breast cancers.
       
  • Laboratory assessment of multiple myeloma
    • Abstract: Publication date: Available online 22 January 2019Source: Advances in Clinical ChemistryAuthor(s): Tracy Morrison, Ronald A. Booth, Kristin Hauff, Philip Berardi, Alissa Visram Laboratory testing plays an essential role in the diagnosis and management of patients with multiple myeloma. A variety of chemistry and molecular assays are routinely used to monitor patient progress, response to treatment and relapse.Here, we have reviewed current literature and core guidelines on the details of laboratory testing in myeloma-related investigations. This includes the use and value of protein electrophoresis, serum free light chain and cytogenetic testing. Furthermore, we discuss other traditional chemistry assays essential to myeloma investigation, and potential interferences that may arise due to the disease nature of myeloma, that is, the presence of a monoclonal immunoglobulin. Finally, we discuss the importance of communication in protein electrophoresis results, where laboratorians are required to relate clinically relevant myeloma-relevant information to the ordering physician on the background of a complex pattern of serum or urine proteins.Laboratory testing in myeloma-related investigation relies on several traditional chemistry assays. However, we anticipate new tests and technologies to become available in the future with improved analytical sensitivity, as well as improved clinical sensitivity in identifying patients who are at high risk of progression to multiple myeloma.
       
  • Glycosylation markers in cancer
    • Abstract: Publication date: Available online 17 January 2019Source: Advances in Clinical ChemistryAuthor(s): Atit Silsirivanit Alteration of glycosylation, a hallmark of cancer, results in the production of tumor-associated glycans or glycoproteins. These molecules are subsequently secreted or membrane-shed into the blood stream and thus serve as tumor-associated markers. Increased glycosylation in cancer is triggered by overexpression of glycoproteins that carry certain specific glycans, increase or decrease of nucleotide sugar donors and altered expression of glycosyltransferase and glycosidase enzymes. In this chapter, the biochemistry and function of glycoprotein, glycan and enzyme markers are reviewed. These glycosylation markers, applicable for detection and monitoring of cancer, include CA19-9, CA125, CEA, PSA and AFP. Because of their specific affinity to distinct sugar moieties, lectins are useful for developing assays to detect these tumor associated glycans and glycoproteins in clinical samples. As such, various enzyme-linked lectin assays (ELLA) have been developed for diagnosis, monitoring and prognosis. Because glycosylation changes occur early in cancer, the detection of tumor associated glycosylation markers using lectin based assays is an effective strategy to improve diagnosis and treatment resulting better outcomes clinically.
       
  • Probing the endogenous peptidomes of cancer for biomarkers: A new endeavor
    • Abstract: Publication date: Available online 27 December 2018Source: Advances in Clinical ChemistryAuthor(s): Pey Yee Lee, Teck Yew Low, Rahman Jamal The life span of cancer patients can be prolonged with appropriate therapies if detected early. Mass screening for early detection of cancer, however, requires sensitive and specific biomarkers obtainable from body fluids such as blood or urine. To date, most biomarker discovery programs focus on the proteome rather than the endogenous peptidome. It has been long-established that tumor cells and stromal cells produce tumor resident proteases (TRPs) to remodel the surrounding tumor microenvironment in support of tumor progression. In fact, proteolytic products of TRPs have been shown to correlate with malignant behavior. Being of low molecular weight, these unique peptides can pass through the endothelial barrier of the vasculature into the bloodstream. As such, the cancer peptidome has increasingly become a focus for biomarker discovery. In this review, we discuss on the various aspects of the peptidome in cancer biomarker research.
       
  • Extracellular vesicle-associated MMPs: A modulator of the tissue
           microenvironment
    • Abstract: Publication date: Available online 23 November 2018Source: Advances in Clinical ChemistryAuthor(s): Masayuki Shimoda Extracellular vesicles (EVs) are small particles that mediate intercellular communications in local and distant microenvironments. Due to their ability to carry bioactive materials such as proteins, nucleic acids, and lipids, and to transfer their cargo into target cells, EVs are thought to be crucial mediators under pathological and physiological conditions. Recent investigations of their protein profiles have revealed the presence of metalloproteinases such as matrix metalloproteinases (MMPs) in EVs from various cell types and body fluids. Although information regarding the biological and clinical significance of MMPs in EVs is still limited, EV-associated MMPs can alter EV cargo by ectodomain shedding, exerting proteolytic activity following uptake by target cells, or directly contributing to degradation of extracellular matrix proteins surrounding cells. This review focuses on recent findings regarding EV-associated MMPs, and we further discuss their potential involvement in human diseases.
       
  • Clinical metabolomics of exhaled breath condensate in chronic respiratory
           diseases
    • Abstract: Publication date: Available online 22 November 2018Source: Advances in Clinical ChemistryAuthor(s): Mauro Maniscalco, Salvatore Fuschillo, Debora Paris, Adele Cutignano, Alessandro Sanduzzi, Andrea Motta Chronic respiratory diseases (CRDs) are complex multifactorial disorders involving the airways and other lung structures. The development of reliable markers for an early and accurate diagnosis, including disease phenotype, and prediction of the response and/or adherence to treatment prescribed are essential points for the correct management of CRDs. Beside the traditional techniques to detect biomarkers, “omics” sciences have stimulated interest in clinical field as they could potentially improve the study of disease phenotype. Perturbations in a variety of metabolic and signaling pathways could contribute an understanding of CRDs pathogenesis. In particular, metabolomics provides powerful tools to map biological perturbations and their relationship with disease pathogenesis.The exhaled breath condensate (EBC) is a natural matrix of the respiratory tract, and is well suited for metabolomics studies. In this article, we review the current state of metabolomics methodology applied to EBC in the study of CRDs.
       
  • Novel glomerular filtration markers
    • Abstract: Publication date: Available online 16 November 2018Source: Advances in Clinical ChemistryAuthor(s): Jaya A. George, Verena Gounden Chronic kidney disease is currently assessed by estimated glomerular filtration rate, a mathematical construct based on creatinine or creatinine and cystatin concentration. Creatinine-based equations have improved with standardization efforts and the Modification of Diet in Renal Disease Study (MDRD) and CKD-Epidemiology Collaboration Study (CKD-EPI).Because the measurement of creatinine is subject to interference from non-GFR determinants, alternative markers have long been sought. These have included cystatin C and low molecular weight proteins like β2-microglobulin and beta trace protein. Tubular disease often occurs before glomerular filtration is impaired and investigators have investigated the excretion of other low molecular weight proteins such as Neutrophil Gelatinase-Associated Lipocalin (NGAL) and Kidney Injury Molecule-1 and N-acetyl-β-d-glucosaminidase. While preliminary, there is some evidence linking these analytes with GFR, disease stage and mortality.Although asymmetrical dimethyl arginine, an inhibitor of nitric oxide, has been shown to be associated with progression of renal disease, symmetric dimethyl arginine may be a better marker. Recent work has also explored the potential of microRNA (miRNA) analysis and metabolomics studies to further elucidate this complex pathophysiologic disease process.Investigators hope to improve our ability to detect CKD by the use of test panels, i.e., various marker combinations thereof. Unfortunately, most of these markers lack standardization unlike traditional measures that rely on creatinine and cystatin C measurement.
       
  • Anti-angiogenic isoform of vascular endothelial growth factor-A in
           cardiovascular and renal disease
    • Abstract: Publication date: Available online 16 November 2018Source: Advances in Clinical ChemistryAuthor(s): Ryosuke Kikuchi, Megan Stevens, Kazuhiro Harada, Sebastian Oltean, Toyoaki Murohara Accumulating evidence suggests that pathologic interactions between the heart and the kidney can contribute to the progressive dysfunction of both organs. Recently, there has been an increase in the prevalence of cardiovascular disease (CVD) and chronic kidney disease (CKD) due to increasing obesity rates. It has been reported that obesity causes various heart and renal disorders and appears to accelerate their progression.Vascular endothelial growth factor-A (VEGF-A) is a major regulator of angiogenesis and vessel permeability, and is associated with CVD and CKD. It is now recognized that alternative VEGF-A gene splicing generates VEGF-A isoforms that differ in their biological actions. Proximal splicing that includes an exon 8a sequence results in pro-angiogenic VEGF-A165a, whereas distal splicing inclusive of exon 8b yields the anti-angiogenic isoform of VEGF-A (VEGF-A165b).This review highlights several recent preclinical and clinical studies on the role of VEGF-A165b in CVD and CKD as a novel function of VEGF-A. This review also discusses potential therapeutic approaches of the use of VEGF-A in clinical settings as a potential circulating biomarker for CVD and CKD.
       
  • Emicizumab (ACE910): Clinical background and laboratory assessment of
           hemophilia A
    • Abstract: Publication date: Available online 16 November 2018Source: Advances in Clinical ChemistryAuthor(s): Giuseppe Lippi, Emmanuel J. Favaloro Congenital hemophilia A, a relatively common and sometimes life-threatening bleeding disorder, is caused by inherited deficiency of clotting factor (F) VIII. The adoption of an appropriate medical and environmental prophylaxis is critical for long-term management of hemophilia because it will considerably reduce the number of both mild and severe bleeding episodes. Among the many therapeutic options that have become available over the past decades, ACE910 (also known as emicizumab) is a bispecific immunoglobulin G antibody characterized by its unique ability to bind FIX or FIXa on one arm and FX on the other, thus abrogating FVIII activity in vivo. Several phase I to III clinical trials have now been published, confirming the clinical efficacy and relative safety of this new agent for long-term prophylaxis of hemophilia A, especially those patients having FVIII inhibitors. The recent regulatory clearance of ACE910 in many countries will hence impose additional challenges to clinical laboratories because the panel of available tests will need to address the emerging issue of monitoring patients treated with this novel anti-hemophilic agent by using conventional as well as innovative approaches. Therefore, this article is aimed to provide an update on clinical background and challenges of laboratory assessment in hemophilia A patients undergoing ACE910 administration.

  • Fecal Calprotectin
    • Abstract: Publication date: Available online 1 October 2018Source: Advances in Clinical ChemistryAuthor(s): Ruth M. Ayling, Klaartje Kok Calprotectin is a 36 kDa member of the S100 family of proteins. It is derived predominantly from neutrophils and has direct antimicrobial effects and a role within the innate immune response. Calprotectin is found in various body fluids in proportion to the degree of any existing inflammation and its concentration in feces is about six times that of plasma. Measurement of fecal calprotectin is a useful surrogate marker of gastrointestinal inflammation. It has a high negative predictive value in ruling out inflammatory bowel disease (IBD) in undiagnosed, symptomatic patients and a high sensitivity for diagnosing the disease making it useful as a tool for prioritising endoscopy. In patients with known IBD, fecal calprotectin can be a useful tool to assist management, providing evidence of relapse or mucosal healing to enable therapy to be intensified or reduced.There are a number of commercial calprotectin assays with marked difference in performance as judged by external quality assessment and at present no standardised reference material exists. Various factors may affect results including age, medication and day to day variation. Laboratories should therefore be mindful of the characteristics of their own assay and factors that may affect results.
       
  • Serum Ethanolamine Plasmalogen and Urine M yo-Inositol as Cognitive
           Decline Markers
    • Abstract: Publication date: Available online 30 August 2018Source: Advances in Clinical ChemistryAuthor(s): Ryouta Maeba, Atsushi Araki, Yoshinori Fujiwara Recent studies have suggested that metabolic disorders, particularly type 2 diabetes mellitus (T2DM), and dementia, including Alzheimer's disease (AD), were linked at the clinical and molecular levels. Brain insulin deficiency and resistance may be key events in AD pathology mechanistically linking AD to T2DM. Ethanolamine plasmalogens (PlsEtns) are abundant in the brain and play essential roles in neuronal function and myelin formation. As such, PlsEtn deficiency may be pathologically relevant in some neurodegenerative disorders such as AD. Decreased brain PlsEtn associated with dementia may reflect serum PlsEtn deficiency. We hypothesized that myo-inositol plays a role in myelin formation through its facilitation of PlsEtn biosynthesis. Excessive urinary myo-inositol (UMI) loss would likely result in PlsEtn deficiency potentially leading to demyelinating diseases such as dementia. Accordingly, measurement of both serum PlsEtn and baseline UMI excretion could improve the detection of cognitive impairment (CI) in a more specific and reliable manner. To verify our hypothesis, we conducted a clinical observational study of memory clinic outpatients (MCO) and cognitively normal elderly (NE) for nearly 4.5 years. We demonstrated that serum PlsEtn concentration associated with UMI excretion was useful for predicting advancing dementia in patients with mild CI. Because hyperglycemia and associated insulin resistance might be a leading cause of increased baseline UMI excretion, serum PlsEtn quantitation would be useful in detecting CI among the elderly with hyperglycemia. Our findings suggest that myo-inositol is a novel candidate molecule linking T2DM to AD.
       
  • Glutathione as a Marker for Human Disease
    • Abstract: Publication date: Available online 23 August 2018Source: Advances in Clinical ChemistryAuthor(s): Garrett Teskey, Rachel Abrahem, Ruoqiong Cao, Karo Gyurjian, Hicret Islamoglu, Mariana Lucero, Andrew Martinez, Erik Paredes, Oscar Salaiz, Brittanie Robinson, Vishwanath Venketaraman Glutathione (GSH), often referred to as “the master antioxidant,” participates not only in antioxidant defense systems, but many metabolic processes, and therefore its role cannot be overstated. GSH deficiency causes cellular risk for oxidative damage and thus as expected, GSH imbalance is observed in a wide range of pathological conditions including tuberculosis (TB), HIV, diabetes, cancer, and aging. Consequently, it is not surprising that GSH has attracted the attention of biological researchers and pharmacologists alike as a possible target for medical intervention. Here, we discuss the role GSH plays amongst these pathological conditions to illuminate how it can be used as a marker for human disease.
       
  • Long Noncoding RNAs: Advances in Lipid Metabolism
    • Abstract: Publication date: Available online 23 August 2018Source: Advances in Clinical ChemistryAuthor(s): Yongzhi Zeng, Kun Ren, Xiao Zhu, Zhi Zheng, Guanghui Yi Long noncoding RNAs (lncRNAs) are an important group of pervasive noncoding RNAs (>200 nt) proposed to be crucial regulators of numerous physiological and pathological processes. Through interactions with RNA, chromatin, and protein, lncRNAs modulate mRNA stability, chromatin structure, and the function of proteins (including transcription factors). In addition, to their well-known roles in the modulation of cell growth, apoptosis, neurological disease progression and cancer metastasis, these large molecules have also been identified as likely mediators of lipid metabolism. In particular, lncRNAs orchestrate adipogenesis; fatty acid, cholesterol, and phospholipid metabolism and transport; and the formation of high-density and low-density lipoproteins (HDLs and LDLs). LncRNAs also appear to target several transcription factors that play essential roles in the regulation of lipid metabolism, such as liver X receptors (LXRs), sterol regulatory element binding proteins (SREBPs), and peroxisome proliferator-activated receptor γ (PPARγ). Better understanding the regulatory roles of lncRNAs in dyslipidemia, atherosclerosis, and adipogenesis will reveal appropriate strategies to treat these diseases. In this review, we review recent progress in lncRNA-mediated regulation of lipid metabolism, as well as its role in the regulation of adipogenesis.
       
  • Protein Carbamylation in Chronic Kidney Disease and Dialysis
    • Abstract: Publication date: Available online 23 August 2018Source: Advances in Clinical ChemistryAuthor(s): Joshua Long, Xavier Vela Parada, Sahir Kalim Protein carbamylation is a nonenzymatic posttranslational protein modification that can be driven, in part, by exposure to urea's dissociation product, cyanate. In humans, when kidney function is impaired and urea accumulates, systemic protein carbamylation levels increase. Additional mediators of protein carbamylation have been identified including inflammation, diet, smoking, circulating free amino acid levels, and environmental exposures. Carbamylation reactions on proteins are capable of irreversibly changing protein charge, structure, and function, resulting in pathologic molecular and cellular responses. Carbamylation has been mechanistically linked to the biochemical pathways implicated in atherosclerosis, dysfunctional erythropoiesis, kidney fibrosis, autoimmunity, and other pathological domains highly relevant to patients with chronic kidney disease. In this review, we describe the biochemical impact of carbamylation on human proteins, the mechanistic role carbamylation can have on clinical outcomes in kidney disease, the clinical association studies of carbamylation in chronic kidney disease, including patients on dialysis, and the promise of therapies aimed at reducing carbamylation burden in this vulnerable patient population.
       
  • Free Circulating miRNAs Measurement in Clinical Settings: The Still
           Unsolved Issue of the Normalization
    • Abstract: Publication date: Available online 23 August 2018Source: Advances in Clinical ChemistryAuthor(s): Martina Faraldi, Marta Gomarasca, Giuseppe Banfi, Giovanni Lombardi Circulating molecules that are released into the circulation in response to specific stimuli are considered potential biomarkers for physiological or pathological processes. Their effective usefulness as biomarkers resides in their stability and high availability in all the biological fluids, combined with the limited invasiveness of intervention. Among the circulating molecules, miRNAs represent a novel class of biomarkers as they possess all the required characteristics such as sensitivity, predictivity, specificity, robustness, translatability, and noninvasiveness.miRNAs are small non-coding RNAs, that act as inhibitors of protein translation, and intervene in the complex network of the post-transcriptional mechanisms finely regulating gene expression.The emerging role of miRNAs as potential biomarkers for clinical applications (e.g., cancer and cardiovascular diseases diagnosis and prediction, musculoskeletal disease diagnosis and bone fracture risk prediction), however, requires the standardization of miRNA processing, from sample collection and sample storage, to RNA isolation, RNA reverse-transcription, and data analyses. Normalization is one of the most controversial issues related to quantitative Real-Time PCR data analysis since no universally accepted normalization strategies and reference genes exist, even more importantly, for circulating miRNA quantification. As it is widely demonstrated that the choice of different normalization strategies influences the results of gene expression analysis, it is important to select the most appropriate normalizers for each experimental set. This review discloses on the different strategies adopted in RT-qPCR miRNA normalization and the concerning issues to highlight on the need of a universally accepted methodology to make comparable the results produced by different studies.
