Abstract Background To verify that the single nucleotide polymorphisms (SNP) of vitamin D receptor (VDR) may lead to genetic susceptibility to left ventricular hypertrophy (LVH), the present study was designed to study four SNPs of VDR associated with LVH in maintenance hemodialysis (MHD) patients of Han nationality. Methods 120 MHD patients were recruited at Department of Nephrology, Zhongnan Hospital of Wuhan University to analyze the expression of genotype, allele and haplotype of Fok I, Bsm I, Apa I and Taq I in blood samples, and to explore their correlation with blood biochemical indexes and ventricular remodeling. Results The results showed that the risks of CVD included gender, dialysis time, heart rate, SBP, glycated hemoglobin, calcium, iPTH and CRP concentration. Moreover, LAD, LVDd, LVDs, IVST and LVMI in B allele of Bsm I increased significantly. Fok I, Apa I and Taq I polymorphisms have no significant difference between MHD with LVH and without LVH. Further study showed that VDR expression level decreased significantly in MHD patients with LVH, and the B allele was positively correlated with VDR Expression. Conclusion VDR Bsm I gene polymorphism may predict cardiovascular disease risk of MDH patients, and provided theoretical basis for early detection and prevention of cardiovascular complications.

<b><i>Background:</i></b> Patients with maintenance hemodialysis (MHD) generally have a microinflammatory state. The aim of this study was to investigate the effects of hemodialysis (HD) combined with hemoperfusion (HP) on microinflammatory state in elderly patients with MHD. <b><i>Methods:</i></b> One hundred and fifty elderly patients with MHD were randomly divided into the control group and the observation group. The control group received simple HD treatment, and the observation group received combined HD + HP treatment on the basis of the control group. After 6 months of continuous treatment, the patients were evaluated to compare the quality of life, inflammation, adverse reactions, and nutritional indicators in the 2 groups before and after treatment. <b><i>Results:</i></b> There was no significant difference in the quality of life between the 2 groups before treatment. After treatment, the scores of psychological aspects, physiological aspects, social aspects, environmental aspects, and independent ability in the observation group were higher than those in the control group, with statistical significance (<i>p</i> &#x3c; 0.05). There was no statistical significance in the level of inflammation between 2 groups before treatment. After treatment, the levels of hs-CRP, Hcy, IL-6, and TNF-α in the observation group were significantly lower than those in the control group, with statistical significance (<i>p</i> &#x3c; 0.05). The incidence of dry mouth, skin reaction, neuritis, and subcutaneous tissue fibrosis in the observation group was lower than that in the control group, with statistical significance (<i>p</i> &#x3c; 0.05). There was no statistical significance in nutritional level indexes between 2 groups before treatment (<i>p</i><sub>1</sub> &#x3e; 0.05). After treatment, the levels of hemoglobin, total protein, albumin, and transferrin in the observation group were significantly higher than those in the control group, with statistical significance (<i>p</i> &#x3c; 0.05). <b><i>Conclusion:</i></b> The clinical effect of HD combined with HP in elderly MHD patients is significant, which can effectively reduce the incidence of adverse reactions and inflammation in the patients and improve the quality of life and nutritional indicators of the patients.

Objective. To explore the clinical implications of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) for diagnosing frailty in patients with maintenance hemodialysis (MHD) and their correlations with patient prognosis. Methods. A total of 185 patients with MHD admitted to the hemodialysis center of our hospital were selected, 72 of whom were diagnosed with frailty according to the Chinese version of Tilburg Frailty Indicator (TFI). The relevant data were collected, and the influencing factors of frailty in MHD patients were analyzed by one-way analysis of variance (ANOVA) and multivariate logistic regression. The value of NLR and PLR in diagnosing frailty in MHD patients was observed, and patients’ all-cause mortality was compared during the 3-year follow-up. The influences of different levels of NLR and PLR on the survival of MHD patients were investigated. Results. Multivariate regression analysis identified that serum albumin, dialysis adequacy, NLR, and PLR are independent risk factors for frailty in MHD patients ( P < 0.05 ). The area under the receiver operating characteristic (ROC) curve of NLR and PLR in diagnosing frailty in MHD patients was 0.859 and 0.799, respectively. Compared with the nonfrailty group, the 3-year mortality was higher, and the 3-year survival rate assessed by survival analysis was lower in the frailty group ( P < 0.05 ). Patients with high NLR and PLR levels showed a lower 3-year survival rate. Conclusions. Dialysis adequacy, serum albumin, NLR, and PLR are independently associated with frailty in MHD patients. NLR and PLR are of a certain diagnostic value for frailty in MHD patients. MHD patients with frailty have an unfavorable prognosis, as of those with high NLR and PLR levels.

Abstract Introduction There is a high prevalence of hypertension in maintenance hemodialysis patients. Information regarding prevalent pattern of antihypertensive medications will help modify it to prevent future cardiovascular morbidity and mortality. Materials and Methods In this cross-sectional study, patients on maintenance hemodialysis, aged ≥18 years visiting Nephrology outpatient department (OPD) from April 2019 to May 2020 were included. The patients were divided into two groups based on their dialysis vintage, ≤12 months and >12 months. Their antihypertensive medication patterns and two-dimensional (2D) echocardiography (ECHO) findings were compared. Independent t-test was used to compare continuous variables. One-way analysis of variance was used to study the antihypertensive drug-dosing pattern in both the groups. Results Out of 250 patients, 131 had a dialysis vintage of ≤12 months, whereas 119 had a vintage of >12 months. There was no significant difference in the number of antihypertensive agents used in either of the vintage groups. Calcium channel blockers (87.02 and 89.07%, respectively, in ≤12 and >12 months' vintage groups) and β blockers (64.12 and 65.54%, respectively, in ≤12 and >12 months' vintage groups) were the commonly used antihypertensive agents. Metoprolol use was higher in ≤12 months' group, whereas carvedilol usage was higher in >12 months' group (p = 0.028). Mean pill burden was more than five in both the groups. Concentric left ventricular hypertrophy was significantly more common in >12 months' group. Renin–angiotensin system (RAS) blocking agent use was limited to 3% of patients. Conclusion This study shows a high antihypertensive pill burden in dialysis patients likely due to underlying chronic volume overload in addition to the perceived efficacy of certain class of drug in a frequent dosing pattern. Low use of RAS blocking agent was also underlined. This study highlights the need to bring about changes in the antihypertensive prescription pattern in line with the existing evidence.

AbstractWomen have a longer life expectancy than men in the general population. However, it has remained unclear whether this advantage is maintained in patients undergoing maintenance hemodialysis. The aim of this study was to compare the risk of mortality, especially infection-related mortality, between male and female hemodialysis patients. A total of 3065 Japanese hemodialysis patients aged ≥ 18 years old were followed up for 10 years. The primary outcomes were all-cause and infection-related mortality. The associations between sex and these outcomes were examined using Cox proportional hazards models. During the median follow-up of 8.8 years, 1498 patients died of any cause, 387 of whom died of infection. Compared with men, the multivariable-adjusted hazard ratios (95% confidence interval) for all-cause and infection-related mortality in women were 0.51 (0.45–0.58, P < 0.05) and 0.36 (0.27–0.47, P < 0.05), respectively. These findings remained significant even when propensity score-matching or inverse probability of treatment weighting adjustment methods were employed. Furthermore, even when the non-infection-related mortality was considered a competing risk, the infection-related mortality rate in women was still significantly lower than that in men. Regarding all-cause and infection-related deaths, women have a survival advantage compared with men among Japanese patients undergoing maintenance hemodialysis.

AbstractSome hemodialysis patients are not suitable for creation of an arteriovenous fistula (AVF) or arteriovenous graft (AVG). However, they can receive a tunneled cuffed central venous catheter (tcCVC), but this carries risks of infection and mortality. We aimed to evaluate the safety and effectiveness of brachial artery transposition (BAT) versus those of tcCVC. This retrospective study evaluated hemodialysis patients who underwent BAT or tcCVC placement because of severe heart failure, hand ischemia, central venous stenosis or occlusion, inadequate vessels for creating standard arteriovenous access, or limited life expectancy. The primary outcome was whole access circuit patency. Thirty-eight patients who underwent BAT and 25 who underwent tcCVC placement were included. One-year patency rates for the whole access circuit were 84.6% and 44.9% in the BAT and tcCVC groups, respectively. The BAT group was more likely to maintain patency (unadjusted hazard ratio: 0.17, 95% confidence interval: 0.05–0.60, p = 0.006). The two groups did not have significantly different overall survival (log-rank p = 0.146), although severe complications were less common in the BAT group (3% vs. 28%, p = 0.005). Relative to tcCVC placement, BAT is safe and effective with acceptable patency in hemodialysis patients not suitable for AVF or AVG creation.

Background and objectives: Fibrin sheath (FS) formation around tunneled central venous catheters (CVC) increases the risk of catheter-related bloodstream infections due to bacterial adherence to a biofilm. We sought to investigate whether FS disruption (FSD) at the time of CVC removal or exchange affects infectious outcomes in patients with CVC-related infections. Design, setting, participants, and measurements: Retrospective cohort study of 307 adult maintenance hemodialysis patients aged 18 years or older at a single center academic-based hemodialysis program (UHN, Toronto) who developed CVC-related infections requiring CVC removal or exchange between January 2000 and January 2019. Exposure was FSD at the time of CVC removal or exchange. Outcomes were infectious metastatic complications, recurrent infection with the same organism within 1 year, or death due to infection. We created a Markov Multi-State Model (MMSM) to assess patients’ trajectories through time as they transitioned between states. A time-to-event analysis was performed, adjusted for clinically relevant factors. Results: There was no significant relationship between FSD status at the time of CVC removal, the development of infectious complications in the multivariable model (adjusted HR = 0.71, 95% CI 0.09−5.80, p = 0.76), or mortality from infection (HR = 0.84, 95% CI 0.34−2.11, p = 0.73). Conclusions: FSD at the time of CVC removal was not associated with increased risk of infectious complications or death due to infection. Further prospective study is needed to determine whether FSD contributes to reducing CVC infectious related complications.

Background: Patients under maintenance hemodialysis are at increased risk of malnutrition, causing from multitude of factors. Present study aims to assess the prevalence of malnutrition among maintenance hemodialysis patients using both modified subjective global assessment score and body mass index, compare them and assess the sensitivity and specificity of body mass index for detecting malnutrition, along with determining a new cutoff value for BMI that better represent the maintenance hemodialysis patient’s nutritional status. Methods: This was a cross-sectional study conducted in the hemodialysis unit of Bangabandhu Sheikh Mujib Medical University, Sir Salimullah Medical College Mitford Hospital, BIRDEM General Hospital and National Institute of Kidney Diseases & Urology; among 80 adult CKD patients who were on regular (≥2 sessions per week) maintenance hemodialysis for more than 3 months without any acute infection, during the period of July 2016 to June 2017. Nutritional assessment was done for each patient using modified SGA score along with BMI. Sensitivity analysis of WHO recommended cutoff value for BMI was done among the study population using modified SGA score as gold standard test for detection of malnutrition among the respondents. ROC curve was used to estimate the best fitting cutoff value of BMI that showed highest sensitivity, specificity and accuracy for detracting malnutrition among maintenance hemodialysis patients. Results: The study participants were predominantly male (66.3%) and from age group 45 to 59 years (36.3%). Modified SGA score detected 90.0% of the study population as malnourished. WHO recommended 18.5 kg/m2 cutoff value was also used to detect malnutrition among study population and 13.8% were found to be malnourished, with a sensitivity and specificity of 12.5% and 75.0% respectively. Accuracy was found to be 18.8%. Using ROC curve, 23.1 kg/m2 was found to be the best fitting cutoff value of BMI for the study population to detect malnutrition. With a sensitivity of 47.2%, specificity of 37.5% and accuracy of 46.3%. Conclusion: BMI showed low sensitivity for detecting malnutrition among patients under maintenance hemodialysis, compared to modified SGA score and should be avoided as a screening tool, but 23.1 kg/m2 cutoff value for BMI showed potential to be used as an easy to use and quick tool for detecting malnutrition among such patients. Further study with larger sample size could shed more light on this. JOPSOM 2021; 40(1): 14-21
