Background. Respiratory symptoms are usually underestimated in patients with chronic kidney disease undergoing maintenance hemodialysis. Therefore, we set out to investigate the prevalence of patients chronic dyspnea and the relationship of the symptom to lung function indices.Methods. Twenty-five clinically stable hemodialysis patients were included. The mMRC dyspnea scale was applied before and after hemodialysis. Spirometry, single breath nitrogen test, arterial blood gases, static maximum inspiratory (Pimax⁡) and expiratory (Pemax⁡) muscle pressures, and mouth occlusion pressure (P0.1) were also measured.Results. Despite normal spirometry, all patients (100%) reported mild to moderate degree of chronic dyspnea pre which was reduced after hemodialysis. The sole predictor of (Δ) mMRC was the (Δ)P0.1(r=0.71,  P<0.001). ThePimax⁡was reduced before and correlated with the duration of hemodialysis (r=0.614,  P<0.001), whilst after the session it was significantly increased (P<0.001). Finally (Δ) weight was correlated with the (Δ)Pimax⁡  %pred(r=0.533,  P=0,006) and with the (Δ) CV(%pred)(r=0.65,  P<0.001).Conclusion. We conclude that dyspnea is the major symptom among the CKD patients that improves after hemodialysis. The neuromechanical dissociation observed probably is one of the major pathophysiologic mechanisms of dyspnea.

Aim: (1) To describe the whole blood content of thiamine diphosphate (TDP), a biologically active form of vitamin B1 in end-stage kidney disease patients treated with hemodialysis (HD); (2) to establish the impact of a single HD procedure on TDP blood concentrations; and (3) to describe potential explanatory variables influencing TDP dialysis related losses, including dialysis prescription, vitamin B1 dietary intake and supplementation. Methods: Single-center, cross-sectional study in 50 clinically stable maintenance HD patients. The assessment of whole blood TDP with the High Performance Liquid Chromatography method, before and after a single, middle-week dialysis session and analysis of clinical and laboratory parameters potentially influencing TDP status Results: We report a significant difference in TDP levels before and after HD sessions - 42.5 (95% CI 38.7-46.2) μg/L and 23.6 (95% CI 18.9-28.2) μg/L, respectively (p = 0.000). The magnitude of intradialytic TDP changes is highly variable among individuals and is negatively associated only with the body weight of the patients (p < 0.013). Vitamin B1 dietary intake and supplementation do not influence whole blood TDP and dialysis-related loss of TDP. Conclusions: TDP, a bioactive compound of vitamin B1, is substantially lost during the HD procedure, and the magnitude of its loss is associated with the patient's body weight but it is not influenced by vitamin B1 dietary intake and standard supplementation dose.

Abstract Background and Aims Patients with end-stage kidney disease (ESKD) are known to have higher plasma concentrations of metabolic waste products than healthy individuals. Patients with Primary Hyperoxaluria (PH), a rare congenital cause of ESKD, suffer from hepatic overproduction of the metabolic end product oxalate. Plasma oxalate (POx) levels are determined in the diagnostic and therapeutic work-up for PH. Remarkably, correct interpretation of these values is hampered by the absence of knowledge concerning POx levels in patients with ESKD due to common causes. Method In this observational study, we obtained POx values in patients with ESKD due to another cause than PH, to establish reference values in this patient group. We collected blood samples from 120 adults with eGFR &lt; 15 mL/min/1.73 m2 who required maintenance hemodialysis or peritoneal dialysis at the Amsterdam UMC. Results While there was a wide variation in POx levels in patients with ESKD, the median was 50 umol/L and lowest values were twice the upper reference limit that applies to healthy individuals (6.7 umol/L). Conclusion This study shows that POx levels of 50 umol/L are not necessarily suggestive for PH which contradicts the current literature. This study could lead to a paradigm shift in the diagnostic and therapeutic work-up for patients with ESKD.

Increased serum levels of uric acid have been associated with the onset and development of chronic kidney disease (CKD), cardiovascular disease, and mortality, through several molecular pathogenetic mechanisms, such as inflammation and oxidative stress. Oxidative stress is present even in the early stages of CKD, progresses parallelly with the deterioration of kidney function, and is even more exacerbated in end-stage renal disease patients undergoing maintenance hemodialysis. Although acting in the plasma as an antioxidant, once uric acid enters the intracellular environment; it behaves as a powerful pro-oxidant. Exogenous intake of antioxidants has been repeatedly shown to prevent inflammation, atherosclerosis and oxidative stress in CKD patients. Moreover, certain antioxidants have been proposed to exert uric acid-lowering properties. This review aims to present the available data regarding the effects of antioxidant supplements on both oxidative stress and uric acid serum levels, in a population particularly susceptible to oxidative damage such as CKD patients.

Pleural effusions occur frequently in mechanically ventilated patients, but no consensus exists regarding the clinical benefit of effusion drainage. We sought to determine the impact of thoracentesis on gas exchange in patients with differing severities of acute lung injury (ALI). A retrospective analysis was conducted on therapeutic thoracenteses performed on intubated patients in an adult surgical intensive care unit of a tertiary center. Effusions judged by ultrasound to be 400 mL or larger were drained. Subjects were divided into groups based on their initial P:F ratios: normal >300, ALI 200 to 300, and acute respiratory distress syndrome (ARDS) <200. Baseline characteristics, physiologic variables, arterial blood gases, and ventilator settings before and after the intervention were analyzed. The primary end point was the change in measures of oxygenation. Significant improvements in P:F ratios (mean ± SD) were seen only in patients with ARDS (50.4 ± 38.5, P = 0.001) and ALI (90.6 ± 161.7, P = 0.022). Statistically significant improvement was observed in the pO2 (31.1, P = 0.005) and O2 saturation (4.1, P < 0.001) of the ARDS group. The volume of effusion removed did not correlate with changes in individual patient's oxygenation. These data support the role of therapeutic thoracentesis for intubated patients with abnormal P:F ratios.

Pulmonary and systemic hemodynamics and arterial blood gases were measured in anesthetized and mechanically ventilated dogs before and after oral or intravenous administration of ethanol. Increases in mean pulmonary artery pressure and pulmonary vascular resistance occurred. Platelet antiserum-induced thrombocytopenia inhibition of prostaglandin synthesis with meclofenamate, or alpha-adrenergic blockade did not alter the pulmonary pressor response to ethanol. However, the increase in resistance following ethanol was abolished by hyperoxia and potentiated by hypoxia. Thus, it appears that the effect of ethanol is to augment hypoxic pulmonary vasoconstriction, whereas ethanol per se has no independent pulmonary pressor activity.

Background: Procalcitonin (PCT) has emerged as a marker of infection and it could be useful for detection of systemic bacterial infections in patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). The aim of this study was to assess the influence of HD membrane permeability to PCT serum levels in noninfected HD patients on maintenance HD. Methods: In a prospective comparative study, we measured PCT serum levels and C reactive protein (CRP) before and after HD in 36 sessions (18 sessions of HD with low-flux = Group L; and 18 sessions with high flux membranes = Group H), in 18 chronic HD patients without history of infection. Results: Sessions of HD by high-flux membranes (Group H) displayed median PCT values that were significantly decreased after dialysis (0.21 ng/mL [0.13-0.41] vs. 0.18 ng/mL [0.10-0.24], p <0.001) but median PCT significantly increased after HD sessions by low-flux membranes (Group L) (0.21 ng/mL [0.14-0.33] vs. 0.25 ng/mL [0.14-0.36]; p = 0.008). CRP values were significantly increased after HD in both groups. CRP correlated with PCT values only in group H before HD (r = 0.49; p = 0.36). Conclusions: PCT represents a useful diagnostic marker for systemic bacterial infection. However, there is a need for specific reference ranges to be developed in patients with renal failure undergoing HD; also, PCT serum levels must be interpreted according to the HD membrane permeability.
