RESUMO

INTRODUCTION: Non-oxidized (n-ox) PTH could better reflect PTH activity. We have evaluated the evolution of n-ox PTH and intact PTH (iPTH) in hemodialyzed (HD) patients over a period of 1 year. MATERIAL AND METHODS: We measured iPTH and n-ox PTH in 66 stable HD patients and we measured iPTH and n-ox PTH at baseline and after 1, 3, 6 and 12 months. We considered that no significant changes in iPTH and n-ox PTH occurred if two consecutives measurements of iPTH and n-ox PTH for the same patient remained in the baseline value ±43%. We also considered that changes over time were concordant if both values of the same patients increased or decreased together (in the same direction) by more than 43%. RESULTS: The median [p25; p75] was 229.4 [1.5,4; 352.5] pg/mL for iPTH and 24.4 [15,1; 38.7] pg/mL for n-ox PTH. N-ox PTH fraction represented 11.3 [9.0; 13.7]% of the total iPTH and the ratio n-oxPTH/iPTH ranged from 5.1 to 35.7%. After 1 year, 84% of the patients presented a perfect concordance of the evolution of the 2 moieties and no severe discordance was noticed. CONCLUSIONS: The percentage of n-ox PTH is stable over time in stable HD patients.

RESUMO

Historically, the determination of low concentration analytes was initially made possible by the development of rapid and easy-to-perform immunoassays (IAs). Unfortunately, typical problems inherent to IA technologies rapidly appeared (e.g. elevated cost, cross-reactivity, lot-to-lot variability, etc.). In turn, liquid chromatography tandem mass spectrometry (LC-MS/MS) methods are sensitive and specific enough for such analyses. Therefore, they would seem to be the most promising candidates to replace IAs. There are two main choices when implementing a new LC-MS/MS method in a clinical laboratory: (1) Developing an in-house method or (2) purchasing ready-to-use kits. In this paper, we discuss some of the respective advantages, disadvantages and mandatory requirements of each choice. Additionally, we also share our experiences when developing an in-house method for cortisol determination and the implementation of an "ready-to-use" (RTU) kit for steroids analysis.

RESUMO

Vitamin D deficiency and insufficiency has become a pandemic health problem with a consequent increase of requests for determining circulating levels of 25-hydroxyvitamin D [25(OH)D]. However, the analytical performance of these immunoassays, including radioimmunoassay and ELISA, is highly variable, and even mass spectrometric methods, which nowadays serves as the gold standard for the quantitatively determination of 25(OH)D, do not necessarily produce comparable results, creating limitations for the definition of normal vitamin D status ranges. To solve this problem, great efforts have been made to promote standardization of laboratory assays, which is important to achieve comparable results across different methods and manufacturers. In this review, we performed a systematic analysis evaluating critically the advantages and limits of the current assays available for the measure of vitamin D status, i.e., circulating 25(OH)D and its metabolites, making suggestions that could be used in the clinical practice. Moreover, we also suggest the use of alternatives to blood test, including standardized surveys that may be of value in alerting health-care professionals about the vitamin D status of their patients.

RESUMO

It has been more than 80 years since the discovery of vitamin D and its ability to cure rickets in children. Vitamin D is a secosteroid and comes in two distinct forms, vitamin D2 and vitamin D3. During the last 40 years, the synthesis and metabolism of vitamin D were elucidated and more than 50 metabolites of vitamin D have been discovered, though commercial measurement procedures have been developed for only a few of them. The clinical significance of vitamin D in calcium and phosphorus homeostasis is well appreciated. However, recent epidemiological data have indicated that it has several extra-skeletal physiologic actions which are still a matter of scientific debate. Both research findings and the debate around the interpretation of the research results have created increased interest in more measurements of vitamin D. With the ever growing family of measurable vitamin D metabolites and the measuring techniques comes a question: What metabolic product will provide the right answers and which is the best way to measure it. The right choice of analytical technique is connected with the question of which metabolite we aim to measure, what is its serum concentration, and the purpose of the measurement. The aim of the first part of this review is to provide a brief overview of vitamin D metabolism and a more detailed analysis of the existing methods and the status of standardization for the measurement of 25-hydroxyvitamin D.

RESUMO

Background Simultaneous measurement of 25(OH)D and 24,25(OH)2D is a new tool for predicting vitamin D deficiency and allows evaluating CYP24A1 lack of function. Interpretation of 24,25(OH)2D should be performed according to 25(OH)D levels and a ratio, called the vitamin D metabolite ratio (VMR) has been proposed for such a purpose. Unfortunately, the VMR can be expressed in different ways and cannot be used if 24,25(OH)2D concentrations are undetectable. Here, we propose evaluating the enzyme activity taking into consideration the probability that a normal population presents undetectable 24,25(OH)2D concentrations according to 25(OH)D levels. We thus retrospectively measured 25(OH)D and 24,25(OH)2D in a population of 1200 young subjects to evaluate the 25(OH)D threshold above which the enzyme was induced. Methods Serum samples from 1200 infants, children, adolescent and young adults were used to simultaneously quantify 25(OH)D and 24,25(OH)2D by LCMS/MS. Results Median (interquartile range [IQR]) levels were 20.6 (14.4-27.2) ng/mL for 25(OH)D. 172 subjects (14.3%) presented 24,25(OH)2D values below the LOQ. When 25(OH)D values were <11 ng/mL, 63.1% of subjects presented undetectable 24,25(OH)2D concentrations. Percentage decreased with increasing 25(OH)D values to become 19.7% for 25(OH)D comprised between 12 and 15 ng/mL, 5.1% for 25(OH)D between 16 and 20 and 0.7% for 25(OH)D >21 ng/mL. Conclusions We suggest using a statistical approach to evaluate CYP24A1 function according to 25(OH)D concentrations. Our results also show that vitamin D deficiency, as defined biochemically, could be around 20 ng/mL in infants, children, adolescent and young adults and that vitamin D deficiency could be evaluated on a more individual basis.

RESUMO

Background Previous studies have suggested that exercising may induce cardiac damage. Galectin-3 (Gal-3) and soluble suppression of tumorigenicity 2 (ST2) are very interesting biomarkers for heart failure and myocardial fibrosis. We aimed to compare the kinetics of emerging fibrosis cardiac biomarkers as Gal-3 and ST-2 in endurance runners, and recreational runners before and after a running event represented by a marathon and an ultratrail event. Methods Blood samples were taken from 19 healthy non-elite marathon runners (42 km), 27 ultratour runners (67 km), and 14 recreational runners who represented the control group (10 km) just before the run (T0), just after (T1) and 3 h after (T2), in order to analyze Gal-3, ST2, hsTnT, NT-proBNP, CKMB and hsCRP. We compared the percentage of evolution and the slopes obtained from T0 to T1 (pT0T1) and from T1 to T2 (pT1T2), between the different groups of runners participating in three different races. Results Plasma cardiac biomarker concentrations increased significantly from baseline to immediately post-exercise and most of the time decreased over the subsequent 3-h period. For pT0T1 and pT1T2, the markers Gal-3 and ST2 showed a significant difference between types of run (p < 0.05 and p < 0.0001, respectively). During the recovery time, Gal-3 returned to the baseline values but not ST2 which continued to increase. Conclusions Gal-3 and ST2 are considered as a reflection of cardiac fibrosis and remodeling. The evolution of both was different, particularly after the recovery time. ST2 values exceeding cutoff values at any time.

RESUMO

The assessment of fragility fracture risk based on bone densitometry and FRAX°, although commonly used, has shown some limitations. MicroRNAs (miRNAs) are promising biomarkers known to regulate post-transcriptional gene expression. Many studies have already shown that microRNAs are involved in bone homeostasis by modulating osteoblast and osteoclast gene expression. In this pilot study, we investigated the ability of an miRNA panel (namely, the OsteomiR° score) to predict fragility fracture risk in older people. miRNAs were extracted from the sera of 17 persons who developed a fracture within 3 years of collecting the serum and 16 persons who did not experience fractures in the same period. Nineteen miRNAs known to be involved in bone homeostasis were assessed, and 10 miRNAs were employed to calculate the OsteomiR° score. We found a trend towards higher OsteomiR° scores in individuals who experienced fractures compared to control subjects. The most suitable cut-off that maximized sensitivity and specificity was determined by ROC curve analysis, and a positive predictive value of 68% and a sensitivity of 76% were obtained. The OsteomiR° score was higher in osteopenic and osteoporotic subjects compared to subjects with a normal T score. Additionally, the OsteomiR° score predicted more fracture events than the recommended "need-to-treat" thresholds based on FRAX° 10-year probability. miRNAs reflect impairments in bone homeostasis several years before the occurrence of a fracture. The OsteomiR° score seems to be a promising miRNA panel for fragility fracture risk prediction and might have added value compared to FRAX°. Given the limited cohort size, further studies should be dedicated to validating the OsteomiR° score.

RESUMO

Increased cardiovascular morbidity and mortality in chronic kidney disease (CKD) represents an emerging major health problem. Indeed, disturbances in mineral and bone metabolism occur frequently in CKD and are termed chronic kidney disease - mineral and bone disorder (CKD-MBD). These can lead to cardiovascular pathology, resulting in an increased cardiovascular risk. Bone alkaline phosphatase (BALP) is essential for biomineralization. Recent findings demonstrate a crucial role for BALP in the pathogenesis of vascular calcification and identified it as a promising predictor of mortality in CKD. In conjunction with parathyroid hormone (PTH), serum BALP has been suggested as a biomarker of bone turnover in CKD-MBD. In contrast to PTH, serum BALP demonstrates a lower variability and may thus be better suited for the diagnosis and longitudinal follow-up of bone turnover. The linear association with mortality, compared to the U-shaped curve for PTH, is an additional advantage, making BALP more suitable than PTH as a treatment target in CKD. Here we review the main characteristics of alkaline phosphatase isozymes/isoforms and the various assays currently used in clinical routine laboratories. We also discuss the role of BALP in both physiological and pathological mineralization, and the clinical benefit of BALP determination in CKD.

RESUMO

Successful kidney transplantation (partly) corrects the physiologic and metabolic abnormalities driving chronic kidney disease - mineral and bone disorders. At the same time, renal transplant recipients are exposed to immunosuppressive agents that may affect bone metabolism. Bone biomarkers have been suggested as surrogates of or adjuncts to bone biopsy and imaging techniques to assess bone health and to classify risk of bone loss and fractures. Bone biomarkers may be classified as circulating factors that affect bone metabolism (commonly referred to as bone metabolism markers) or that reflect bone cell number and/or activity (commonly referred to as bone turnover markers). A growing body of evidence shows that successful renal transplantation has a major impact on both bone metabolism and bone turnover. Analytical issues, including the cross-reactivity with fragments, complicate the interpretation of bone biomarkers, especially in the setting of a rapid changing kidney function, as is the case after successful renal transplantation. Overall, bone turnover seems to decline following renal transplantation, but inter-individual variability is substantial. Preliminary evidence indicates that bone biomarkers may be useful in guiding mineral and bone therapy in renal transplant recipients.

RESUMO

BACKGROUND: Matrix-Gla-protein (MGP) is an inhibitor of vascular calcification. Its dephosphorylated and uncarboxylated inactive form, dpucMGP, is a marker of vitamin K status and of cardio-vascular outcomes in chronic kidney disease. We hypothesized that higher serum dpucMGP would be a biomarker of kidney stone disease. METHODS: We measured serum dpucMGP in incident symptomatic kidney stone-formers and non-stone formers at a baseline visit. Symptomatic stone recurrence was assessed in the stones formers over a 5-year period. The association of dpucMGP with incident or recurrent kidney stones was assessed with and without adjustment for clinical, blood, and urine characteristics. RESULTS: There was no significant difference in serum dpucMGP level between 498 stone formers and 395 non-stone former (510 vs 501 pmol/L; p = 0.66). In a multivariable model adjusting for clinical, blood and urine chemistries, higher MGP was associated with lower risk of stone formation (OR = 0.674, 95% CI 0.522-0.870), contrary to previous reports. Among 375 stone formers with 5 years of follow-up, 79 (21%) had symptomatic recurrence. No difference in serum dpucMGP was evident in recurrent versus non-recurrent stone-formers (482 vs 502 pmol/L; p = 0.26). Serum dpucMGP was correlated with cystatin C levels in non stone-formers, incident stone-formers and recurrent stone-formers (r > 0.3, p < 0.0001). CONCLUSION: Elevated serum dpucMGP was not associated with incident or recurrent symptomatic kidney stone events. However, higher level of dpucMGP was associated with lower risk of kidney stone in a multivariable logistic regression model.

RESUMO

With intermittent vitamin D supplementation, serum 25-hydroxyvitamin D (25OHD) levels may remain stable only if the dosing interval is shorter than 3 months, the ideal perhaps being about 1 month. Recent data support moderate daily vitamin D doses instead of high intermittent doses, notably in elderly patients prone to falls. The level of evidence is low, however, with no head-to-head comparisons of clinical outcomes such as fractures and falls in groups given identical dosages daily versus intermittently. A challenge to daily vitamin D supplementation in France is the absence of a suitable pharmaceutical formulation. In addition, daily dosing carries a high risk of poor adherence. Until suitable vitamin D3 formulations such as tablets or soft capsules each containing 1000 or 1500 IU become available, we suggest intermittent supplementation according to 2011 GRIO guidelines. Among the available dosages, the lowest should be preferred, with the shortest possible interval, e.g., 50,000 IU monthly rather than 100,000 every two months.

RESUMO

Sclerostin is sometimes presented as a promising biomarker in assessing bone health both in the general population and chronic kidney disease patients. However, it is still unclear whether it has any true added value compared to existing bone biomarkers in predicting bone turnover and/or bone density in chronic kidney disease patients. A wealth of papers has been published to evaluate the association between sclerostin and vascular calcifications development or even as prognostic biomarker for mortality, but often with conflicting results. Standardization and harmonization of analytical techniques is a prerequisite to advance clinical knowledge in sclerostin.

RESUMO

PURPOSE OF REVIEW: The review critically appraises the most recent and important meta-analyses that have assessed the effect of vitamin D supplementation on bone health in the older population. RECENT FINDINGS: Vitamin D status is generally lower in study participants with bone wasting. However, studies on the effects of vitamin D supplementation on bone health, summarized in different meta-analyses, have provided conflicting results, likely because of the heterogeneity between studies. Interventional studies performed using more physiological doses of vitamin D (i.e. avoiding very large, nonphysiological doses) or in study participants with low vitamin D status have provided more beneficial effects on bone health. SUMMARY: Meta-analyses assessing the impact of vitamin D in the treatment of osteoporosis are heterogeneous in their conception or their results and sometimes have included inappropriate studies to answer the useful research question for the clinician, making the interpretation and the clinical use of these conflicting meta-analyses quite difficult.

RESUMO

Age-related cognitive decline arises from alterations in brain structure as well as in sleep-wake regulation. Here, we investigated whether preserved wake-dependent regulation of cortical function could represent a positive factor for cognitive fitness in aging. We quantified cortical excitability dynamics during prolonged wakefulness as a sensitive marker of age-related alteration in sleep-wake regulation in 60 healthy older individuals (50-69 y; 42 women). Brain structural integrity was assessed with amyloid-beta- and tau-PET, and with MRI. Participants' cognition was investigated using an extensive neuropsychological task battery. We show that individuals with preserved wake-dependent cortical excitability dynamics exhibit better cognitive performance, particularly in the executive domain which is essential to successful cognitive aging. Critically, this association remained significant after accounting for brain structural integrity measures. Preserved dynamics of basic brain function during wakefulness could therefore be essential to cognitive fitness in aging, independently from age-related brain structural modifications that can ultimately lead to dementia.

RESUMO

CONTEXT: Hypophosphataemic rickets (HR) is a group of rare hereditary renal phosphate wasting disorders caused by mutations in the PHEX, FGF23, DMP1, ENPP1, CLCN5, SLC9A3R1, SLC34A1 or SLC34A3. OBJECTIVE: A large kindred with 5 HR patients were recruited with dominant inheritance. The study was undertaken to investigate underlying genetic defects in the HR patients. DESIGN: Patients and their family members were initially analyzed for PHEX and FGF23 mutations by PCR-sequencing and copy number analysis. Exome sequencing was subsequently performed to identify novel candidate genes. RESULTS: PHEX and FGF23 mutations were not detected in the patients. No copy number variation was observed in the genome by CytoScan HD Array analysis. Mutations in the DMP1, ENPP1, CLCN5, SLC9A3R1, SLC34A1 or SLC34A3 were not found as well by exome sequencing. A novel c.979-96 T>A mutation in the SGK3 gene was found to be strictly segregated with patients in a heterozygous pattern and was not present in the normal family members. The mutation is located 1 bp downstream of highly conserved adenosine branch point, resulted in exon 13 skipping and in-frame deletion of 29 amino acids, which is part of protein kinase domain and contains Thr-320 phosphorylation site required for its activation. Protein tertiary structure modelling showed significant structural change in the protein kinase domain following the deletion. CONCLUSIONS: The c.979-96 T>A splice mutation in the SGK3 gene causes exon 13 skipping and deletion of 29 amino acids in the protein kinase domain. The SGK3 mutation may cause autosomal dominant HR.

RESUMO

Mounting evidence indicates that sclerostin, a well-known inhibitor of bone formation, may qualify as a clinically relevant biomarker of chronic kidney disease-related mineral and bone disorder (CKD-MBD), including abnormal mineral and bone metabolism and extraskeletal calcification. For this purpose, in this study we investigate the extent to which circulating sclerostin, skeletal sclerostin expression, bone histomorphometric parameters, and serum markers of bone metabolism associate with each other. Bone biopsies and serum samples were collected in a cohort of 68 end-stage kidney disease (ESKD) patients. Serum sclerostin levels were measured using 4 different commercially available assays. Skeletal sclerostin expression was evaluated on immunohistochemically stained bone sections. Quantitative bone histomorphometry was performed on Goldner stained tissue sections. Different serum markers of bone metabolism were analyzed using in-house techniques or commercially available assays. Despite large inter-assay differences for circulating sclerostin, results obtained with the 4 assays under study closely correlated with each other, whilst moderate significant correlations with skeletal sclerostin expression were also found. Both skeletal and circulating sclerostin negatively correlated with histomorphometric bone and serum parameters reflecting bone formation and turnover. In this study, the unique combined evaluation of bone sclerostin expression, bone histomorphometry, bone biomarkers, and serum sclerostin levels, as assessed by 4 different assays, demonstrated that sclerostin may qualify as a clinically relevant marker of disturbed bone metabolism in ESKD patients.

RESUMO

Parathyroid hormone (PTH) is a key player of bone remodelling in patients suffering from Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD). Serum PTH concentrations are thus frequently measured in CKD patients. Nevertheless, this determination is far from simple. PTH stability can be an issue and degradation of the peptide can be important if storage is not properly done. Biologically active PTH circulates together with fragments, which can be detected by some immunoassays. There is, up to now, no standardization of the assays available on the market, which can lead to some confusion when patients are followed with different methods. The upper end of the reference ranges provided by some manufacturers have not been properly established and are sometimes far too high. Finally, PTH can be oxidized in vivo and thus become inactive, while still quantified by immunoassays. In this Editorial, we will try to highlight some of these issues on PTH measurement.

RESUMO

INTRODUCTION: Determination of creatinine and estimation of Glomerular Filtration Rate (GFR) rapidly before injection of contrast media provides early detection of high-risk patients for acute kidney failure. Hence, a rapid point-of-care (POC) device (result in 30 s) allowing creatinine measurement and eGFR could be of interest. To validate this method, we considered a population referred for measuring GFR. METHODS: Iohexol plasma clearance was used to measure GFR. For each subject, enzymatic creatinine was quantified with two different devices: in plasma with the Roche Cobas analyzer and in capillary blood with the Nova Biomedical POC device. Both values of creatinine were used in the CKD-EPI equation for estimated glomerular filtration rate (eGFR). eGFR using POC was compared to eGFR using Cobas and to mGFR by Passing Bablok regression, calculation of bias, precision and accuracy (or concordance) within 30%. Also, we calculated the rate of discrepant staging (eGFR >60 or ≤ 60 when mGFR is actually ≤60 and > 60) with both creatinine methods. RESULTS: 120 subjects (52 ±â€¯13 years, 49% of women) were included. Mean mGFR was 77 ±â€¯27 mL/min/1.73m2 with 29 patients presenting mGFR <60 mL/min/1.73m2. Passing- Bablok regression comparing eGFR obtained with the POC and the Cobas was: eGFRPOC = -0.1 (95% CI: -7.4; 3.0) + 1.06 (95% CI: 1.00; 1.15) x eGFRCOBAS. Mean bias was 3.7 ±â€¯14.1 mL/min/1.73m2. Concordance within 30% was 82%. Compared to mGFR, Passing-Bablok with POC was: eGFRPOC = -11.5 (95% CI: -22.9; -0.7) + 1.15 (95% CI: 1.02; 1.29) x mGFR. Mean bias was 0.1 ±â€¯17.6 mL/min/1.73m2. Accuracy within 30% was 81%. Between eGFRCOBAS and mGFR, mean bias was -3.7 ±â€¯12.5 mL/min/1.73m2. Accuracy within 30% was 95%. With POC (and Cobas), 3.3% (0.8%) of patients would have been considered with GFR > 60 mL/min/1.73m2 whereas mGFR it was ≤60 and 10% (9.2%) of them would have been considered with GFR ≤60 mL/min/1.73m2 when mGFR was >60. CONCLUSION: Creatinine measured with the POC has an acceptable performance when used with the CKD-EPI equation to estimate GFR. Its ability to detect GFR <60 mL/min/1.73m2 is not significantly different from the classical Roche assay. StatSensor Creatinine (Nova Biomedical) can be used for GFR screening before contrast media injection.

RESUMO

Healthy aging is defined as the process of developing and maintaining the functional ability that enables wellbeing in older age. Healthy aging is dependent upon intrinsic capacity, a composite of physical and mental capacities, and the environment an individual inhabits and their interactions with it. Maintenance of musculoskeletal health during aging is a key determinant of functional ability. Sarcopenia, osteoporosis and osteoarthritis, are a triad of musculoskeletal diseases of aging that are major contributors to the global burden of disease and disability worldwide. The prevention and management of these disorders is of increasing importance with pressure mounting from the aging population. In a new initiative, the Chinese Medical Association, Chinese Society of Osteoporosis and Bone Mineral Research, and the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases jointly organized a symposium to discuss current practices and policies in the management of musculoskeletal aging. The meeting allowed experts from Europe and China to share their experience and recommendations for the management of these three major diseases. Discussing and analyzing similarities and differences in their practice should lead, through a mutual enrichment of knowledge, to better management of these diseases, in order to preserve intrinsic capacity and retard the age-related degradation of physical ability. In future, it is hoped that sharing of knowledge and best practice will advance global strategies to reduce the burden of musculoskeletal disease and promote healthy aging tailored to meet the individual patient's needs.
