Non-Invasive, Non-Contact Heart Monitoring of Hemodialysis Patients with a Micropower Impulse Radar Technique

Background The accurate assessment of liver fibrosis among hemodialysis patients with chronic hepatitis C (CHC) is important for both treatment and for follow up strategies. Applying the non-invasive methods in general population with viral hepatitis have been successful but the applicability of the aminotransferase/platelet ratio index (APRI) or the fibrosis-4 index (FIB-4) in hemodialysis patients need further evaluation. Materials and methods We conducted a prospective, multi-center, uremic cohort to verify the applicability of APRI and FIB-4 in identifying liver fibrosis by reference with the standard transient elastography (TE) measures. Results There were 116 CHC cases with valid TE were enrolled in our analysis. 46 cases (39.6%) were classified as F1, 35 cases (30.2%) as F2, 11 cases (9.5%) as F3, and 24 cases (20.7%) as F4, respectively. The traditional APRI and FIB-4 criteria did not correctly identify liver fibrosis. The optimal cut-off value of APRI was 0.28 and of FIB-4 was 1.91 to best excluding liver cirrhosis with AUC of 76% and 77%, respectively. The subgroup analysis showed that female CHC hemodialysis patients had better diagnostic accuracy with 74.1% by APRI. And CHC hemodialysis patients without hypertension had better diagnostic accuracy with 78.6% by FIB-4. Conclusions This study confirmed the traditional category level of APRI and FIB-4 were unable to identify liver fibrosis of CHC hemodialysis patients. With the adjusted cut-off value, APRI and FIB-4 still showed suboptimal diagnostic accuracy. Our results suggest the necessary of TE measures for liver fibrosis in the CHC uremic population.

Accuracy Measures

Abstract Background Assessment of the central venous pressure (CVP) is an essential hemodynamic parameter for monitoring the dialyzing patients. Our objective of the present study is to investigate the accuracy of CVP measurement by internal jugular vein US in comparison to the direct measurement by the central venous catheters for hemodialysis patients. We included 106 patients; where their CVP was assessed in two different non invasive US methods (CVPni) separately and in combination and the obtained measurements were correlated to the invasive measurements (CVPi) by catheters. Results By method 1, there is a highly significant positive correlation between CVPni and CVPi (ρ < 0.001) and a Pearson correlation coefficient (r = 0.913 n = 93), and by method 2, there is also a highly significant positive correlation between the CVPni and CVPi in both groups (r = 0.832, 95%, n = 106, p < 0.001), 1.935 was the cut-off point for prediction of CVP ≥ 10cmH20. For differentiation between patients with CVP < 10cmH20 and ≥ 10cmH20, the accuracy measures (sensitivity, specificity, PPV, NPV, and overall accuracy) were 100%, 79.31%, 74.47%, 100%, and 87.10% by method 1, and were 91.11%, 85.48%, 82.00%, 92.98%, and 87.85% by method 2, while the combination of both methods had gained 88.57%, 89.66%, 83.78%, 92.86%, and 89.25%, respectively. Conclusion The US offered a reliable and non-invasive tool for monitoring CVP. The present study has a novelty of combining more than one US method and this had reported higher accuracy measures and outperformed the use of a single method.

The Impact

Vit-D deficiency (20 ng / mL) and deficiency (20-29 ng / mL) are common side effects in people with chronic disease V or End stage Renal Disease on dialysis. In addition to the lack of exposure to nutrients and sun, reduced Vit-D and body composition, obesity, and racial differences also play a role. In addition, due to a deficiency of 25 (OH) D, serum levels of 1, 25 (OH) 2D decreased over time in CKD patients, as well as non-invasive detection of 25 (OH) D by associated renal cells, increased fibroblast factor -23, and a decrease in functional tissue. Vit-D deficiency causes secondary hyperparathyroidism and associated side effects, such as high hyperparathyroidism and hypercalcemia, requiring surgical parathyroidectomy or the use of calcimimetics. This document examines the available evidence and underscores the importance of Vit-D supplementation in hemodialysis patients. To assess the strength and critically review the available evidence on impact of Vit-D in survival of hemodialysis patients. Vit-D has a survival advantage in patients with CKD-MBD, however we need randomized controlled trial in hemodialysis patients with matched controls given placebo, to prove benefits of Vit-D in terms of all cause and cause specific mortality.
