Cutaneous and Vascular Deposits of 18F-NaF by PET/CT in the Follow-Up of Patients with Pseudoxanthoma Elasticum. J Clin Med 2021; 10:jcm10122588. [PMID: 34208205 PMCID: PMC8230828 DOI: 10.3390/jcm10122588] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 06/02/2021] [Accepted: 06/08/2021] [Indexed: 12/19/2022] Open
Abstract
Active microcalcification of elastic fibers is a hallmark of pseudoxanthoma elasticum and it can be measured with the assessment of deposition of 18F-NaF using a PET/CT scan at the skin and vascular levels. It is not known whether this deposition changes over time in absence of specific therapy. We repeated in two years a PET/CT scan using 18F-NaF as a radiopharmaceutical in patients with the disease and compared the deposition at skin and vessel. Furthermore, calcium score values at the vessel wall were also assessed. Main results indicate in the vessel walls that calcification progressed in each patient; by contrast, the active microcalcification, measured and target-to-background ratio showed reduced active deposition. By contrast, at skin levels (neck and axillae) the uptake of the pharmaceutical remains unchanged. In conclusion, because calcification in the arterial wall is not specific for pseudoxanthoma elasticum condition, the measurement of the deposition of 18F-NaF in the neck might be potentially used as a surrogate marker in future trials for the disease.

Abstract
INTRODUCTION AND OBJECTIVE Familial hypercholesterolaemia (FH) is the most common genetic disorder associated with premature coronary artery disease due to the presence of LDL-C cholesterol increased from birth. It is underdiagnosed and undertreated. The primary objective of the ARIAN project was to determine the number of patients diagnosed with FH after implementing a new screening procedure from the laboratory. MATERIAL AND METHODS This project was designed as a retrospective analysis by consulting the computer system. We selected from databases serum samples from patients ≥ 18 years with direct or calculated LDL-C>250mg/dL from 1 January 2017 to 31 December 2018. Once secondary causes had been ruled out, the requesting primary care physician was notified that their patient might have FH and to arrange a priority appointment in the lipid unit. All patients with a score of ≥ 6 points according to the Dutch Lipid Clinic Criteria were proposed for a genetic study RESULTS: By December 30th, 2020, 24 centres out of the initial 55 had submitted results. The number of patients analysed up to that point was 3,266,341, which represents 34% of the population served in those health areas (9,727,434). CONCLUSIONS The identification of new subjects with FH through this new strategy from the laboratory and their referral to lipid units should increase the number of patients treated in lipid units and initiate familial cascade screening.

Abstract
OBJECTIVES To describe the prevalence of insulin resistance (IR) in patients with established rheumatoid arthritis (RA) and to analyse the contribution of cumulative inflammatory burden and other factors to its development. DESIGN Observational cross-sectional study. PARTICIPANTS Patients with RA and controls matched for age, sex and Body Mass Index. We excluded patients with diabetes. SETTINGS Patients from an RA inception cohort at Hospital Regional Universitario de Málaga, Spain, were recruited between September 2016 and May 2018. PRIMARY AND SECONDARY OUTCOME MEASURES IR was evaluated using the homeostasis model assessment for IR and beta-cell function and the quantitative insulin sensitivity check index. Other variables included the cumulative 28-Joint Disease Activity Score (DAS28) with C reactive protein (CRP) body composition and cytokines. Two logistic regression models were constructed to identify factors associated with IR in patients with RA. RESULTS Eighty-nine patients with RA and 80 controls were included. The prevalence of IR was similar in both cases and controls. Inflammatory activity was controlled appropriately in patients during follow-up (mean DAS28 3.1 (0.8)). The presence of IR in patients with RA was associated with obesity (OR 6.01, 95% CI 1.9 to 8.7), higher cumulative DAS28-CRP values during follow-up (OR 2.8, 95% CI 1.3 to 6.0), and higher interleukin-1β levels (OR 1.6, 95% CI 1.1 to 2.4). The second model showed that the risk of IR increased by 10% for each kilogram of excess body fat. CONCLUSION In patients with well-controlled, established RA, IR is associated mainly with poorer control of inflammation from diagnosis and with obesity, specifically total fat mass.

Abstract
Patients have been showing a growing interest in taking active participation in decision making, and having the opportunity to drive clinical investigation. This is more common for patients who have a rare disease than for those with more prevalent diseases. The EuroSoftCalc.Net COST Action, a group of clinicians and researchers involved in the dystrophic calcification process held a meeting in which three representatives of patients’ associations, coming from Portugal, France and Spain, discussed the role of patients and their associations, namely in the Action, and also the main concerns in their countries. The disparities in health care between European Union countries with regard to connective tissue calcifying diseases, and the existing conflicts of interest, were a matter of debate during the meeting. As a consequence of the presentations and the debate that followed, it became clear that, despite their countries, the main concerns of the patients are identical, namely a lack of specific therapy and follow-up clinical guidelines, delays in the diagnosis, difficulties in getting members to enrol to associations, and/or difficulties with doctors’ explanations for the diseases. The attendees also agreed that EuroSoftCalc.Net group should help to set up new associations where no Patient Associations presently exist, and, furthermore, should release diagnosis and follow-up guidelines, especially helpful in countries, and/or for diseases, where no multidisciplinary consultations are available.

Abstract
Pseudoxanthoma elasticum (PXE) is a genetic disease considered as a paradigm of ectopic mineralization disorders, being characterized by multisystem clinical manifestations due to progressive calcification of skin, eyes, and the cardiovascular system, resembling an age-related phenotype. Although fibroblasts do not express the pathogenic ABCC6 gene, nevertheless these cells are still under investigation because they regulate connective tissue homeostasis, generating the “arena” where cells and extracellular matrix components can promote pathologic calcification and where activation of pro-osteogenic factors can be associated to pathways involving mitochondrial metabolism. The aim of the present study was to integrate structural and bioenergenetic features to deeply investigate mitochondria from control and from PXE fibroblasts cultured in standard conditions and to explore the role of mitochondria in the development of the PXE fibroblasts’ pathologic phenotype. Proteomic, biochemical, and morphological data provide new evidence that in basal culture conditions (1) the protein profile of PXE mitochondria reveals a number of differentially expressed proteins, suggesting changes in redox balance, oxidative phosphorylation, and calcium homeostasis in addition to modified structure and organization, (2) measure of oxygen consumption indicates that the PXE mitochondria have a low ability to cope with a sudden increased need for ATP via oxidative phosphorylation, (3) mitochondrial membranes are highly polarized in PXE fibroblasts, and this condition contributes to increased reactive oxygen species levels, (4) ultrastructural alterations in PXE mitochondria are associated with functional changes, and (5) PXE fibroblasts exhibit a more abundant, branched, and interconnected mitochondrial network compared to control cells, indicating that fusion prevail over fission events. In summary, the present study demonstrates that mitochondria are modified in PXE fibroblasts. Since mitochondria are key players in the development of the aging process, fibroblasts cultured from aged individuals or aged in vitro are more prone to calcify, and in PXE, calcified tissues remind features of premature aging syndromes; it can be hypothesized that mitochondria represent a common link contributing to the development of ectopic calcification in aging and in diseases. Therefore, ameliorating mitochondrial functions and cell metabolism could open new strategies to positively regulate a number of signaling pathways associated to pathologic calcification.

Abstract
BACKGROUND The aim of this study is to confirm the diagnostic performance of the Chylomicron to very low-density lipoproteins triglycerides (CM/VLDL-TG) ratio, the triglycerides to cholesterol ratio (TG/TC) and a dichotomic rule including the tryglycerides to apolipoprotein B (TG/APOB) ratio for the presence of Type I hyperlipoproteinemia (HPLI) in patients with severe hypertriglyceridemia (sHTG) that were at high risk for familial chylomicronemia syndrome (FCS). METHODS Two cohorts (derivation and validation) of patients with sHTG were included in the study. Anthropometric, clinical, biochemical and genetic data were obtained. The CM/VLDL-TG, TG/TC and TG/APOB ratios were calculated. Finally, a diagnostic performance study was developed to establish sensitivity, specificity and cut-offs by a ROC curve analysis in the derivation cohort as well as agreement and predictive values in the validation cohort. RESULTS Patients with FCS in both cohorts showed an earlier presence in pancreatitis, greater number of acute pancreatitis episodes and lower BMI. FCS patients also showed higher ratios of CM/VLDL-TG, TG/TC and TG/APOB ratios, whereas their HDL-C, LDL-C and APOB levels were lower than in non-FCS patients. Sensitivity and agreement were low for both the TG/TC and TG/APOB ratios, although predictive values were good. The CM/VLDL-TG ratio showed greatest sensitivity, specificity, agreement and predictive values for cut-off of 3.8 and 4.5. CONCLUSIONS Our results suggest that in subjects at high risk of FCS a total serum TG/TC ratio or TG/APOB ratio are feasible to initially screen for HLPI; however, a CM/VLDL-TG ratio ≥4.5 is a better diagnostic criterion for HPLI.

Abstract
Objectives: The worldwide SARS-COV2 pandemic has impacted the health of workers and companies. The aim is to quantify it according to sick leave. Methods: Using ICD-9 codes, we analyzed Ibermutua records of all sick leaves during the first trimester of 2020, compared to during the same months of 2017, 2018, and 2019. We stratified the analysis by causes, patient sex, activity sectors, and regional data. All sick leaves were adjusted by the number of Ibermutua-affiliated persons in each period. Results: In March 2020, there was an unprecedented (116%) increase in total sick leaves, mainly due to infectious and respiratory diseases. Men and women were equally affected. All activity sectors were impacted, with the highest increase (457%) observed among health-related workers, especially due to contagious disease. The incidences of sick leaves were heterogeneous among different regions. Cost-analysis of sick leaves during the first trimester of 2020 compared with in previous years showed 40.3% increment (mean 2,813 vs. 2,005 € per 100 affiliated workers). Conclusions: The SARS-COV2 pandemic is having a huge impact on workers' health, as shown by data regarding sick leaves in March 2020. This is associated with greater economic burden for companies, both due to the cost associated with sick leaves and the losses in productivity due to confinement.

Abstract
Cardiovascular disease risk is increased in survivors of testicular cancer because of exposure to treatment (chemotherapy and radiotherapy), as well as modification in lifestyle. Our aim was to assess the presence of subclinical arteriosclerosis in survivors of testicular cancer in comparison with a control group. This was a cross-sectional, observational, case–control study including 50 survivors of Germ Cell Tumor (GCT) (14 years of follow-up) and 53 age-matched controls with no cancer. We registered clinical data, cardiovascular risk factors, physical and Mediterranean questionnaires, intima-media thickness and plaque at carotid and femoral arteries by ultrasound, calcium score at the abdominal aorta, and liver steatosis by computed tomography, and applied analytical tests to quantify metabolic risk factors and inflammation markers. Patients showed a trend toward greater intima-media thickness (IMT) and plaques than controls, as well as a higher calcium score in the abdominal aorta. Remarkably, patients had higher waist circumference, insulin resistance (HOMA-IR), and liver steatosis, but lower physical activity and high-density lipoprotein (HDL) cholesterol than controls (all p < 0.05). In multivariate analyses, only common vascular risk factors were associated with subclinical arteriosclerosis. As a conclusion, in our study, a higher rate of subclinical arteriosclerosis in testicular cancer survivors was associated with classical metabolic risk factors and lifestyle, but not with exposure to chemotherapy.

Abstract
AIMS Our primary objective was to improve risk assessment for fatal and non-fatal cardiovascular events in a working population, mostly young and healthy. METHODS We conducted a prospective cohort study to derive a survival model to predict fatal and non-fatal 10-year cardiovascular risk. We recruited 992,523 workers, free of diagnosed cardiovascular disease at entry, over six years, from 2004-2009. We divided the sample into two independent cohorts: a derivation one (626,515 workers; from 2004-2006) and a temporal validation one (366,008 workers; over 2007-2009). Then, we followed both cohorts over 10 years and registered all fatal and non-fatal cardiovascular events. We built a new risk calculator using an estimation of cardiovascular biological age as a predictor and named it IberScore. There were remarkable differences between this new model and Systematic Coronary Risk Evaluation (SCORE) (in both the specification and the equation). RESULTS Over the 10-year follow-up, we found 3762 first cardiovascular events (6‰) in the derivation cohort. Most of them (80.3%) were non-fatal ischaemic events. If we had been able to use our model at the beginning of the study, we had classified in the 'high-risk' or 'very high-risk' groups 82% of those who suffered a cardiovascular event during the follow-up. All the post-estimation tests showed superior performance (true positive rate: 81.8% vs 11.8%), higher discrimination power and better clinical utility (standardised net benefit: 58% vs 13%) for IberScore when compared to SCORE. CONCLUSION Risk assessment of fatal and non-fatal cardiovascular events in young and healthy workers was improved when compared to the previously used model (SCORE). The latter was not reliable to predict cardiovascular risk in our sample. The new model showed superior clinical utility and provided four useful measures for risk assessment. We gained valuable insight into cardiovascular ageing and its predictors.

Abstract
Background Inorganic pyrophosphate (PPi) plays a major role inhibiting dystrophic calcification. The aim was to analyze levels of PPi in patients having pseudoxanthoma elasticum (PXE), and controls as well as the enzymes who regulate the PPi plasma concentration. Methods We collected fasting blood samples from PXE patients and age- and sex-matched controls in ethylenediamine tetraacetic acid (EDTA) and citrate-theophylline-adenosine-dipyridamole (CTAD) containing tubes. We measured PPi, ENPP1 mass and activity, alkaline phosphatase (AP) and tissue non-specific alkaline phosphatase (TNAP), CD73 and Human Platelet Factor-4 (CXCL4). Results PPi in EDTA and CTAD samples were lower in PXE subjects than in controls (1.11±0.26 vs. 1.43±0.41 µM/L and 0.35±0.15 vs. 0.61±0.18 µM/L respectively, P<0.05). TNAP and liver TNAP activities were also higher in PXE than in controls (80.3±27.0 vs. 63.3±16.4 UI/L and 25.6±14.9 vs. 12.9±9.2 UI/L respectively, P<0.05). ENPP1 mass and activity as well as CD73 were almost identical. There was a weak but significant inverse correlation between TNAP activity and PPi levels (Pearson correlation -0.379, P<0.05) in both groups. Conclusions High TNAP activity seems to contribute to low plasma levels of PPi in subjects with PXE, reinforcing the idea that pharmacological reduction of TNAP activity may help to reduce dystrophic calcification in PXE patients.

Abstract
INTRODUCTION Pathogenic variants in lipoprotein lipase (LPL) and glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) have been described in patients with severe hypertriglyceridaemia. We aimed to optimise high resolution melting (HRM) assays to detect the presence of functional variants in these genes. METHODS One hundred and sixteen patients with severe hypertriglyceridaemia were studied. HRM assays were optimised to scan exons and splice junctions in LPL and GPIHBP1. Sanger sequencing was the reference method. Next-generation-sequencing (NGS) was performed in five patients, including one with Familial Chylomicronemia syndrome (FCS). RESULTS We identified 15 different variants in LPL and 6 in GPIHBP1. The variants revealed with NGS were also detected with HRM, including a rare premature stop codon in LPL (p.Trp421*) and two LPL pathogenic variants in the patient with FCS (p.His80Arg + p.Gly215Glu). Having multiple functional variant alleles was associated with pancreatitis onset at younger ages and higher baseline triglycerides. CONCLUSIONS Our HRM assays detected the presence of functional gene variants that were confirmed with Sanger and NGS sequencing. The presence of multiple functional variant alleles was associated with differences in the clinical profile. Therefore, these assays represent a reliable, cost-effective tool that can be used to complement the NGS approach for gene scanning.

Abstract
Abstract
Background/Introduction
Practice guidelines are agreed on the importance of lifestyle advice for cardiovascular risk reduction as well as cardiovascular risk prediction in planning preventive strategies.
Purpose
To assess the clinical usefulness of the application of the predictive model of cardiovascular risk (CVR) IberScore combined with the recommendations of “Life's Simple 7” (LS7) of the American Heart Association (AHA) in a working population.
Methods
IberScore model is a predictive function for fatal and non-fatal cardiovascular (CV) events derived from a cohort of 774,404 workers (70.4% of the target population) between 16–65 years (average of 35.7 (SD = 10.7)) without CV disease at admission, which was followed for a period of 10 years. Age, sex, total cholesterol, HDL, SBP, glycemia, obesity and a history of dyslipidemia, hypertension and diabetes were used as factors of CVR. Using this model, patients were classified into 4 risk levels. It was also assessed the ideal health status according to the recommendations of “Life's Simple 7” (which includes healthy diet, physical activity, smoking cessation, BMI <25 kg/m2, total cholesterol without treatment <200mg/dl, blood pressure without treatment <120/80 mmHg and basal glycemia <100 mg/dl). Finally, these classifications were compared with the appearance of CV events in a 10-year follow-up.
Results
The results showed a high sensitivity (given that the predictive capacity reached 82% of the cardiovascular events) by using the IberScore, a logistic flexible parametric model to predict 10-year cardiovascular risk. Likewise, the clinical usefulness of the “Life's Simple 7” recommendations could be verified in order to reduce the incidence of total CV events (fatal and non-fatal).
Conclusions
The integration of the predictive model IberScore with the preventive recommendations “Life's simple 7” of the AHA applied to the working population would allow a more efficient cardiovascular prevention.

Abstract
AIM To assess the atherosclerotic burden in hypertensive patients with prediabetes without cardiovascular disease. PATIENTS AND METHODS We included patients with hypertension and prediabetes (fasting blood glucose: 100-125mg/dL and/or glycohemoglobin A1c: 5.7-6.4%), excluding those with established cardiovascular disease or those at very high risk. We recorded major vascular risk factors. Subclinical arteriosclerosis was measured by the ankle/brachial index (ABI) and carotid intima-medial thickness (IMT). Subclinical arteriosclerosis was mild if IMT was >75p adjusted by age and sex and/or ABI was 0.7-0.9 and was considered moderate-severe when there was plaque and/or ABI<0.7. RESULTS We included 53 patients, 63±7 years-old; women: 50,9% (95%CI: 36.8-64.9). Atherosclerotic burden was detected in 66.0% (95%CI: 51.7-78.5) of subjects. 24,5% (95%CI: 13.8-38.3) of patients had mild arteriosclerosis disease and 41.5% (95%CI: 28.1-55.9) had moderate-severe. This allowed us to re-stratified as very high vascular risk the 41.5% (95%CI: 28.1-55.9) of patients. 45.4% (95%CI: 16-74.8) of subjects with moderate initial risk were considered high or very high risk. In multivariate analyses, only smoking was associated with atherosclerotic burden (P=.07). CONCLUSIONS Two thirds of hypertensive patients with prediabetes had subclinical arteriosclerotic disease when they were evaluated by the ankle/brachial index and carotid ultrasonography. Approximately forty percent of patients were re-stratified as very high vascular risk. Nearly half of the prediabetic hypertensive patients initially classified as moderate risk were considered high or very high risk.

Abstract
The introduction of singular therapies, such as proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i), to lower high cholesterol levels requires better classification of patients eligible for intensive lipid lowering therapy. According to the European Medicines Administration, PCSK9i are recommended in primary prevention only in familial hypercholesterolemia (FH) patients. Therefore, an FH diagnosis is not simply an academic issue, because it has many clinical implications. The bases of a diagnosis of FH are not entirely clear. The availability of genetic testing, including large genome-wide association analyses and whole genome studies, has shown that some patients with a clinical diagnosis of definite FH have no mutations in the genes associated with the disease. This fact does not exclude the very high cardiovascular risk of these patients, and an early and intensive lipid lowering therapy is recommended in all FH patients. Because an FH diagnosis is a cornerstone for decisions about therapies, a precise definition of FH is urgently required. This is an expert consensus document from the Spanish Atherosclerosis Society. We propose the following classification: familial hypercholesterolemia syndrome integrated by (1) heterozygous familial hypercholesterolemia: patients with clinically definite FH and a functional mutation in one allele of the LDLR, ApoB:100, and PCSK9 genes; (2) homozygous familial hypercholesterolemia: mutations affect both alleles; (3) polygenic familial hypercholesterolemia: patients with clinically definite FH but no mutations associated with FH are found (to be distinguished from non-familial, multifactorial hypercholesterolemia); (4) familial hypercholesterolemia combined with hypertriglyceridemia: a subgroup of familial combined hyperlipidaemia patients fulfilling clinically definite FH with associated hypertriglyceridemia.

Abstract
BACKGROUND 18F-FDG PET/CT predicts cardiovascular disease. To analyze the predictive value of cardiovascular events from inflammation and arterial calcification in patients who underwent an 18F-FDG PET/CT for lung cancer. METHODS A retrospective study of 274 patients with primary lung neoplasia. We determined: (i) TBR (target-to-background ratio), and (ii) the calcium score, at eight common arterial segments. We took as arteriosclerosis, a TBR ≥1.6 and ≥15 Calcium Score sum. We registered cardiovascular risk factors, comorbidities, histology, stage, treatment, status at the last clinical review, cause of death and cardiovascular event during the follow-up. RESULTS The territory presenting the greatest uptake of 18F-FDG, was the thoracic aorta with an average of 1.77 (± 0.27 TBR) in the aortic arch, while the greatest degree of calcification was obtained in the abdominal aorta (52% with a Calcium Score ≥ 3). 24% of the patients presented a sum Calcium Score ≥15, and 17% a TBR ≥1.6. Patients with high TBR, (17%), had not a higher frequency of cardiovascular comorbidities beforehand, nor did they in the follow-up. However, those with a sum Calcium Score ≥15 (24%), were older, had more cardiovascular risk factors and ischemic events during follow-up. The calcium score, but not the TBR, predicted the emergence of a cardiovascular event (HR 4.9 IC95% 2.1-9.1, P < 0.05). CONCLUSION In our cohort, a high Calcium Score was an independent predictor for developing cardiovascular events.

Abstract
A group of experts convened by the Spanish Society of Arteriosclerosis (SEA) has been in charge of updating the SEA document on the indications of PCSK9 inhibitors (PCSK9i) in clinical practice that was published in 2016. This update is justified by the fact that the data from clinical trials carried out on a large scale with PCSK9i have shown that in addition to their high potency to lower atherogenic cholesterol, they reduce the risk of atherosclerotic cardiovascular disease, both in patients with stable disease, and with recent disease, and with a high degree of security. This update provides the recommendations and level of evidence for the prescription of iPCSK9 in patients with homozygous and heterozygous familial hypercholesterolemia, with atherosclerotic cardiovascular disease, and in primary prevention in patients with very high cardiovascular risk. These recommendations have been established taking into account the concentration of LDL-C, the clinical situation of the patient, the additional risk factors and the cost-effectiveness of their use.

Abstract
BACKGROUND AND AIMS To assess the impact of obesity and being overweight on sickness absence (SA) as a function of healthy/unhealthy metabolic phenotype. METHODS AND RESULTS A total of 173 120 healthy workers who underwent a routine check-up, consisting of a structured interview, anthropometric measurements and blood pressure and fasting blood analysis, were included as the study sample (67.1% males; 49.2% manual workers; mean age 40.6 ± 21.9 years). Workers were classified according to their body mass index (BMI) and metabolic phenotype. A metabolically unhealthy phenotype was defined as the presence of three or more of the following criteria: glycaemia ≥110 mg/dL or previously diagnosed type I/II diabetes or treatment for diabetes; triglycerides ≥150 mg/dL or lipid-lowering therapy; HDL <40/50 mg/dL M/F; blood pressure ≥130/85 mmHg or previously diagnosed hypertension or antihypertensive therapy; waist circumference >102/88 cm M/F. A one-year follow-up was conducted to evaluate the incidence of work-related and non-work-related SA (WRSA/NWRSA). The association of BMI with SA was tested using Poisson regression (standard error correction), segmenting on the basis of metabolic phenotype. The overall percentages of workers who were overweight, obese and/or had a metabolically unhealthy phenotype were 37.7%, 16.3% and 8.8%, respectively. BMI was associated with increased incidence of NWRSA in both phenotypes. It was also associated with WRSA in subjects with a BMI in the range of 35-39.99 kg/m2 and in metabolically healthy individuals. WRSA was lower in subjects with a BMI ≥40 kg/m2 and among metabolically unhealthy individuals. CONCLUSION Obesity is associated with health problems that have a significant impact on SA.

Abstract
The physicochemical deposition of calcium-phosphate in the arterial wall is prevented by calcification inhibitors. Studies in cohorts of patients with rare genetic diseases have shed light on the consequences of loss-of-function mutations for different calcification inhibitors, and genetic targeting of these pathways in mice have generated a clearer picture on the mechanisms involved. For example, generalized arterial calcification of infancy (GACI) is caused by mutations in the enzyme ecto-nucleotide pyrophosphatase/phosphodiesterase-1 (eNPP1), preventing the hydrolysis of ATP into pyrophosphate (PPi). The importance of PPi for inhibiting arterial calcification has been reinforced by the protective effects of PPi in various mouse models displaying ectopic calcifications. Besides PPi, Matrix Gla Protein (MGP) has been shown to be another potent calcification inhibitor as Keutel patients carrying a mutation in the encoding gene or Mgp-deficient mice develop spontaneous calcification of the arterial media. Whereas PPi and MGP represent locally produced calcification inhibitors, also systemic factors contribute to protection against arterial calcification. One such example is Fetuin-A, which is mainly produced in the liver and which forms calciprotein particles (CPPs), inhibiting growth of calcium-phosphate crystals in the blood and thereby preventing their soft tissue deposition. Other calcification inhibitors with potential importance for arterial calcification include osteoprotegerin, osteopontin, and klotho. The aim of the present review is to outline the latest insights into how different calcification inhibitors prevent arterial calcification both under physiological conditions and in the case of disturbed calcium-phosphate balance, and to provide a consensus statement on their potential therapeutic role for arterial calcification.

Abstract
The role of renal excretion of Pi in relation to vascular calcification (VC) in patients in the early stages of chronic kidney disease (CKD) is controversial. Thus, we determine the relation between fractional excretion of phosphorus (FEP) and VC, measured using two methods in a cross-sectional study of patients with stage 3 CKD. We recorded demographic data, anthropometry, comorbidities and active treatment. We measured 24-hour urine FEP and, in serum, measured fibroblast growth factor 23 (FGF23), α-Klotho, intact parathyroid hormone (iPTH), calcium and phosphorus. VC was measured by lateral abdominal radiography (Kauppila index (KI)) and CT of the abdominal aorta (measured in Agatston units). In 57% of subjects, abnormal VC was present when measured using CT, and in only 17% using lateral abdominal radiography. Factors associated with VC using CT were age, cardiovascular risk factors, vascular comorbidity, microalbuminuria and levels of FGF23, phosphorus and calcium x phosphorus product (CaxP); although only age (OR 1.25, 95% CI 1.11 to 1.41), smoking (OR 21.2, CI 4.4 to 100) and CaxP (OR 1.21, CI 1.06 to 1.37) maintained the association in a multivariate analysis. By contrast, only age (OR 1.35, 95% CI 1.07 to 1.74), CaxP (OR 1.14, CI 1.13 to 1.92) and FEP (OR 1.07,95% CI 1004 to 1.14) were associated with abnormal VC in the lateral abdominal radiography. In conclusion, in patients with stage 3 CKD, the detection of VC by abdominal CT is more sensitive than conventional X-rays. Moreover, CaxP is associated with cardiovascular risk factors and vascular comorbidity; quantification of FEPi in these patients provides additional clinical information in advanced VC detected by KI.
