Background: Matrix Gla protein (MGP) is known to act as a potent local inhibitor of vascular calcifications. However, in order to be active, MGP must be phosphorylated and carboxylated, with this last process being dependent on vitamin K. The present study focused on the inactive form of MGP (dephosphorylated and uncarboxylated: dp-ucMGP) in a population of hemodialyzed (HD) patients. Results found in subjects being treated or not with vitamin K antagonist (VKA) were compared and the relationship between dp-ucMGP levels and the vascular calcification score were assessed. Methods: One hundred sixty prevalent HD patients were enrolled into this observational cohort study, including 23 who were receiving VKA treatment. The calcification score was determined (using the Kauppila method) and dp-ucMGP levels were measured using the automated iSYS method. Results: dp-ucMGP levels were much higher in patients being treated with VKA and little overlap was found with those not being treated (5604 [3758; 7836] vs. 1939 [1419; 2841] pmol/L, p <0.0001). In multivariate analysis, treatment with VKA was the most important variable explaining variation in dp-ucMGP levels even when adjusting for all other significant variables. In the 137 untreated patients, dp-ucMGP levels were significantly (p < 0.05) associated both in the uni- and multivariate analysis with age, body mass index, plasma levels of albumin, C-reactive protein, and FGF-23, and the vascular calcification score. Conclusion: We confirmed that the concentration of dp-ucMGP was higher in HD patients being treated with VKA. We observed a significant correlation between dp-ucMGP concentration and the calcification score. Our data support the theoretical role of MGP in the development of vascular calcifications. We confirmed the potential role of the inactive form of MGP in assessing the vitamin K status of the HD patients. [less ▲]

BACKGROUND: Bone-specific alkaline phosphatase (BAP) is now recommended to assess bone turnover in hemodialysis (HD) patients. However, little is known about potential variability between methods available to measure BAP. METHODS: We measured BAP in 76 HD patients with six different assays (Beckman-Coulter Ostase IRMA, Beckman-Coulter Ostase Access, IDS iSYS Ostase, IDS Ostase enzyme immunoassay, DiaSorin Liaison Ostase and Quidel MicroVue BAP). RESULTS: We observed a high correlation between all the assays ranging from 0.9948 (IDS iSYS vs. IDS EIA) to 0.9215 (DiaSorin Liaison vs. Quidel MicroVue). However, using the regression equations, the equivalent concentration of a Beckman-Coulter Access value of 10μg/L can range from 7.7 to 14.4μg/L and of 20μg/L can range from 16.9 to 27.9μg/L with other assays. According to Beckman-Coulter Access, 13%, 50% and 37% of the patients presented BAP values ≤10, between 10 and 20 and ≥20μg/L, respectively. Discrepancies are observed when other assays are used (concordance from 10 to 100%). CONCLUSIONS: Analytical problems leading to inter-method variation should be overcome to improve the usefulness of this marker in clinical practice. According to correlation results, recalibration of BAP assays is necessary but should not be a major issue. [less ▲]

Solid organ transplantation (SOT) currently represents the best therapeutic option in end-stage diseases caused by the irrevocable functional loss of an organ. Still, SOT is associated with immunological and non-immunological injuries, whose severity impacts on early functional recovery and long-term survival of the transplant. Current research focuses on the identification of innovative approaches to 1) attenuate ischemia/reperfusion-induced damage, 2) accelerate processes of tissue repair, and 3) induce in fine graft tolerance. Encouraging observations from both preclinical studies and clinical trials suggest that the administration of mesenchymal stromal cells at the time of SOT might be beneficial, as a result of theirs immunomodulatory, anti-inflammatory and regenerative properties.

From age 30 onwards, kidney function physiologically decreases although this deterioration cannot yet be called chronic kidney disease. The latter appears in those exposed to cardiovascular risk factors associated with inflammation and oxidative stress. A diffuse atherosclerosis then develops Patients with a decreased glomerular filtration rate, especially below the threshold of 45 ml/min, are characterised by a poor physical heath and by cognitive disorders, leading to frailty. In these conditions, a management strategy to reduce the increased risk of acute kidney injury should be outlined and the need for renal replacement therapy be considered. One must try to maintain the best possible quality of life, promoting in some situations a conservative approach. [less ▲]

High blood pressure is very frequent in the elderly; it represents a real threat for the patient’s health and a source of huge costs for the economic system. Systolic hypertension is the most frequent form observed in the old, due to large arteries stiffness. Antihypertensive therapy has proven effective to decrease significantly the cardiovascular morbi-mortality and total mortality in this population. A non pharmacological approach is also very useful, but should not be too restrictive. Blood pressure target in patients older than 65 (and, particularly, in octogenarians) is 150/80 mmHg. Blood pressure should be checked in the upright position before changing the drug dosage. The first line therapy in the old should generally be a calcium channel antagonist or a low dose diuretic.

Successivement au mois de juin 2013 et fin de l’année 2013 sont apparues trois recommandations sur la prise en charge de l’hypertension artérielle. La première relevait de la Société Européenne d’Hypertension et les deux autres de sociétés américaines et internationales. Ces directives accordaient toutes une importante place aux mesures de pression artérielle (PA) en dehors du cabinet de consultation (automesure et mesure ambulatoire de pression sur 24 heures). Elles ont voulu aussi simplifier les cibles de PA à viser qui apparaissent beaucoup moins exigeantes qu’auparavant. Chez les patients âgés, les cibles sont différentes de celles des patients plus jeunes et l’initiation du traitement est d’ailleurs moins rapide. Les bêtabloquants ont été réhabilités dans la stratégie de traitement possible lorsqu’on initie un médicament en présence d’une hypertension artérielle considérée comme nécessitant un médicament antihypertenseur et enfin une stratégie un peu plus claire a été proposée pour l’hypertension artérielle résistante.

The calcium-sensing receptor (CaSR) has been implicated in the ischemia/ reperfusion (I/R) cascade in heart, liver and brain. Renal I/R occurs at the time of transplantation (Tx), with a deleterious impact on early graft function. Here, we retrospectively investigated if the use of cinacalcet, a CaSR agonist, in kidney transplant recipients (KTR) influences early graft recovery. All KTR from 2007 to 2012 in our Academic Hospital were prospectively included in a database. Patients actively treated with cinacalcet on the day of Tx were retrospectively identified from this database and matched with controls on (i) type of donor (living [LD], deceased after brain or circulatory death [DCD]); (ii) cold ischemic time (CIT) ` 1 h; (iii) residual diuresis (` 500 ml); and (iv) donor age (` 5 years). Delayed graft function (DGF) was defined as dialysis requirement after Tx. Baseline characteristics were compared between groups with student’s t-test or Chi-2 as appropriate. The endpoint was the percentage of DGF in both groups. Among 337 KTR, 36 (10.7%) were treated with cinacalcet at Tx. Control group included 61 patients. Characteristics of patients and donors are summarized in the table. DGF occurred in 42 and 23% of cinacalcet-treated and control groups, respectively (p = 0.05). These retro- spective observations suggest that CaSR activation at the time of Tx impairs early graft recovery. [less ▲]

Acute kidney injury (AKI) represents a worldwide public health issue of increasing incidence, with a significant morbi-mortality. AKI treatment mostly relies on supportive manoeuvres in the absence of specific target-oriented therapy. The pathophysiology of AKI commonly involves ischaemia/reperfusion (I/R) events, which cause both immune and metabolic consequences in renal tissue. Similarly, at the time of kidney transplantation (KT), I/R is an unavoidable event which contributes to early graft dysfunction and enhanced graft immunogenicity. Mesenchymal stromal cells (MSCs) represent a heterogeneous population of adult, fibroblast-like multi-potent cells characterized by their ability to differentiate into tissues of mesodermal lineages. Because MSC have demonstrated immunomodulatory, anti-inflammatory and tissue repair properties, MSC administration at the time of I/R and/or at later times has been hypothesized to attenuate AKI severity and to accelerate the regeneration process. Furthermore, MSC in KT could help prevent both I/R injury and acute rejection, thereby increasing graft function and survival. In this review, summarizing the encouraging observations in animal models and in pilot clinical trials, we outline the benefit of MSC therapy in AKI and KT, and envisage their putative role in renal ischaemic conditioning.
