Background: Chronic Kidney Disease (CKD) is associated with mineral and bone disorders (MBD). International guidelines suggest that levels of serum parathormone (PTH) or bone-specific alkaline phosphatase (b-ALP) can be used to evaluate MBD in dialysis patients. The evidence remains moderate and based on transversal studies. <br />Methods: We retrospectively investigated the variations of PTH (ΔPTH) and b-ALP (Δb-ALP) serum concentrations over a short (6-weeks) and a long (one-year) period in a monocentric hemodialysis population. The proportion of patients reaching the critical difference (CD) (50% for PTH and 25% for b-ALP) was calculated. <br />Results: Seventy-seven patientswere included. A significant correlation between PTHand b-ALP levelswas found at baseline (r=0.51). By contrast, no correlation was observed between ΔPTH and Δb-ALP over a 6-week interval (r=0.07). The CD for PTH and b-ALP was reached by 19 and 11 patients, respectively, with 2 patients showing consistent variations of both biomarkers. One year later, measurements were repeated in 48 survivors. <br />No correlation was found between ΔPTH and Δb-ALP (r=0.27). The CD for PTH or b-ALP was reached by 24 patients and 28 patients, respectively, with 6 patients (12.5%) showing opposite results for both biomarkers. <br />Conclusion: This study shows the lack of correlation between ΔPTH and Δb-ALP over time in patients under chronic hemodialysis.

Abstract Background. The evaluation of the peritoneal transport characteristics is mandatory in peritoneal dialysis (PD) patients. This is usually performed in routine clinical practice with a peritoneal equilibration test (PET) using conventional dialysates, with low pH and high glucose degradation product (GDP) concentrations. An increasing proportion of patients are now treated with biocompatible dialysates, i.e. with physiological pH and lower GDP concentrations. This questions the appropriateness to perform a PET with conventional solutions in those patients. The aim of our study is to compare the results of the PET using biocompatible and conventional dialysates, respectively. Methods. Nineteen stable PD patients (13 males, 6 females; mean age: 67.95 ± 2.36 years, mean body surface area: 1.83 ± 0.04 m2, dialysis vintage: 2.95 ± 0.19 years) were included, among which 10 were usually treated with biocompatible and 9 with conventional solutions. Two PETs were performed, within a 2-week interval, in each patient. PET sequence (conventional solution first or biocompatible solution first) was randomized in order to avoid ‘time bias’. Small (urea, creatinine and glucose), middle (beta-2-microglobulin) and large molecules’ (albumin and alpha-2-macroglobulin) dialysate/plasma (D/P) concentration ratios and clearances were measured during each PET. Ultrafiltration (UF) and sodium filtration were also recorded. Results of both tests were compared by the Wilcoxon paired test. Results. No statistical difference was found between both dialysates for small molecule transport rates or for sodium filtration and UF. However, a few patients were not similarly classified for small-solute transport characteristics within the PET categories. Beta-2-microglobulin and albumin D/P ratios at different time points of the PET were significantly higher with the biocompatible, when compared with the conventional, solutions: 0.10 ± 0.03 versus 0.08 ± 0.02 (P < 0.01) and 0.008 ± 0.003 versus 0.007 ± 0.003 (P = 0.01), respectively. A similar difference was also observed for beta-2-microglobulin that was higher with biocompatible dialysates (1.04 ± 0.32 versus 0.93 ± 0.32 mL/min, respectively). Conclusion. Peritoneal transport of water and small solutes is independent of the type of dialysate which is used. This is not the case for the transport of beta-2-microglobulin and albumin that is higher under biocompatible dialysates. Vascular tonus modification could potentially explain such differences. The PET should therefore always be carried out with the same dialysate to make longitudinal comparisons possible. [less ▲]

Orthostatic hypotension (OH) is a rather common phenomenon in clinical practice. It may occur in 5-10 % of normal individuals, but its prevalence increases with age and various pathologies, so that it may rise above 35 % in certain subgroups of patients. OH is associated with various comorbidities, in particular cardio-cerebro-vascular accidents and falls (especially in the elderly), and may even increase mortality. It is, however, difficult to determine whether OH is simply a marker of frailty or whether it is really a risk factor. OH treatment involves physical manoeuvres or medications, which aim at inducing a peripheral vasoconstriction (midodrine, etilefrine) or an increase of circulating blood volume (9-alpha-fluohydrocortisone). However, their use should be cautious, because of a risk of arterial hypertension in supine position. [less ▲]

Orthostatic hypotension (OH) is defined by a drop in arterial blood pressure (BP) of at least 20 mmHg for systolic BP and 10 mmHg for diastolic BP after standing. Symptoms are generally quite typical, but may also be rather vague. Diagnosis may be easily made by the physician in his/ her office, and confirmed, if necessary, by more sophisticated measurements. Pathophysiology is generally rather complex, but mostly involves a defect in the autonomic nervous system, in its sympathetic component. Failure of peripheral vasoconstriction seems to play a more important role than the defect in reflex tachycardia. Causes of OH are multiples. OH may occur in healthy subjects, when exposed to exceptional circumstances, but is more generally associated with various diseases, either neurological disorders or pathologies characterized by hypovolemia. Medications can also aggravate the risk of OH, among which some antihypertensive or psychotropic agents. Elderly people, especially frailty subjects, are exposed to a high risk of OH, whose origin is often multifactorial, and this complication may have serious medical consequences. [less ▲]
