ABSTRACT

ABSTRACT The CONVINCE study, recently published in the New England Journal of Medicine, reveals a groundbreaking 23% reduction in the relative risk of all-cause mortality among end-stage kidney patients undergoing high convective volume hemodiafiltration. This significant finding challenges the conventional use of high-flux hemodialysis and offers hope for improving outcomes in chronic kidney disease patients. While some controversies surround the study's findings, including concerns about generalizability and the causes of death, it is essential to acknowledge the study's design and its main outcomes. The CONVINCE study, part of the HORIZON 2020 project, enrolled 1360 patients and demonstrated the superiority of hemodiafiltration in reducing all-cause mortality overall, as well as in specific patient subgroups (elderly, short vintage, non-diabetic, and those without cardiac issues). Interestingly, it was shown that hemodiafiltration had a protective effect against infection, including COVID-19. Future research will address sustainability, dose scaling effects, identification of subgroups especially likely to benefit and cost-effectiveness. However, for now, the findings strongly support a broader adoption of hemodiafiltration in renal replacement therapy, marking a significant advancement in the field.


RESUMO O estudo CONVINCE, publicado recentemente no New England Journal of Medicine, revela uma redução inovadora de 23% no risco relativo de mortalidade por todas as causas entre pacientes renais em estágio terminal submetidos à hemodiafiltração de alto volume de convecção. Esse achado significativo desafia o uso convencional da hemodiálise de alto fluxo e oferece esperança de melhoria dos desfechos em pacientes com doença renal crônica. Embora algumas controvérsias cerquem os achados do estudo, incluindo preocupações sobre a generalização e as causas de óbito, é essencial reconhecer o desenho do estudo e seus principais desfechos. O estudo CONVINCE, parte do projeto HORIZON 2020, inscreveu 1.360 pacientes e demonstrou a superioridade da hemodiafiltração na redução da mortalidade por todas as causas em geral, bem como em subgrupos específicos de pacientes (idosos, HD de curta duração, não diabéticos e aqueles sem problemas cardíacos). Curiosamente, demonstrou-se que a hemodiafiltração teve um efeito protetor contra infecções, incluindo a COVID-19. Pesquisas futuras abordarão sustentabilidade, efeitos de escalonamento da dose, identificação de subgrupos especialmente propensos a se beneficiar e a relação custo-benefício. No entanto, por ora, os achados apoiam fortemente uma adoção mais ampla da hemodiafiltração na terapia renal substitutiva, marcando um avanço significativo na área.

ABSTRACT

ABSTRACT The desperate attempt to improve mortality, morbidity, quality of life and patient-reported outcomes in patients on hemodialysis has led to multiple attempts to improve the different modes, frequencies, and durations of dialysis sessions in the last few decades. Nothing has been more appealing than the combination of diffusion and convection in the form of hemodiafiltration. Despite the concrete evidence of better clearance of middle weight molecules and better hemodynamic stability, tangible evidence to support the universal adoption is still at a distance. Survival benefits seen in selected groups who are likely to tolerate hemodiafiltration with better vascular access and with lower comorbid burden, need to be extended to real life dialysis patients who are older than the population studied and have significantly higher comorbid burden. Technical demands of initiation hemodiafiltration, the associated costs, and the incremental benefits targeted, along with patient-reported outcomes, need to be explored further before recommending hemodiafiltration as the mode of choice.


RESUMO A tentativa desesperada de melhorar a mortalidade, morbidade, qualidade de vida e desfechos relatados pelos pacientes em indivíduos em hemodiálise levou a diversas tentativas de aprimorar os diferentes modos, frequências e durações das sessões de diálise nas últimas décadas. Nada foi mais atrativo do que a combinação de difusão e convecção na forma de hemodiafiltração. Apesar das evidências concretas de melhor depuração de moléculas de peso médio e melhor estabilidade hemodinâmica, evidências tangíveis para apoiar a adoção universal ainda estão distantes. Os benefícios de sobrevida observados em grupos selecionados que provavelmente toleram a hemodiafiltração com melhor acesso vascular e com menor carga de comorbidades precisam ser estendidos aos pacientes reais em diálise, que são mais velhos do que a população estudada e apresentam uma carga de comorbidades significativamente maior. As exigências técnicas do início da hemodiafiltração, os custos associados e os benefícios incrementais almejados, juntamente com os desfechos relatados pelos pacientes, precisam ser melhor explorados antes de se recomendar a hemodiafiltração como o modo de escolha.

ABSTRACT

Objective To study the risk factors of two-stage citrate anticoagulation in intermittent he-modialysis(IHD)and to establish an unplanned offline prediction model.Methods A retrospective analysis was conducted to include 34 patients and 118 times of treatment with two-stage citrate anticoagulation for IHD in the hospital from January 2019 to February 2023.According to whether the treatment did not reach the treatment time due to the coagulation of the extracorporeal circulation pipeline,118 treatments were divid-ed into the planned units(n=111)and the unplanned units(n=7).Univariate and multivariate logistic re-gression analysis were used to analyze the risk factors of unplanned weaning,and a risk prediction model was established.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of the regression model.Results Univariate analysis showed that there were statistically significant differences in hematocrit(HCT),platelet count(PLT),activated partial thromboplastin time(APTT),and treatment mode between the planned and unplanned units(P<0.05).Multivariate logistic regression analysis showed that HCT and APTT were independent influencing factors for unplanned weaning(P<0.05).The HCT level was represented by A,the APTT level was represented by B,and the prediction model was:Logit(P)=1.304+ 0.206×A-0.378×B.The area under the ROC curve(AUC)of the prediction model was 0.912(95%CI:0.825-0.995,P<0.001),the maximum Youden index was 0.782,the cut off value was 0.113,the sensitivity was 85.7%,and the specificity was 92.5%.Conclusion The prediction model established by multivariate logistic regression analy-sis can make a preliminary judgment on whether coagulation occurs in two-stage IHD treatment.

ABSTRACT

Objective:To observe of the effects of micro-video breakthrough education and thematic workshops in the care of internal fistulae in maintenance haemodialysis patients, to provide a basis for improving prognosis of patients.Methods:This study was a randomized controlled trial. A total of 90 cases of maintenance haemodialysis patients with endocardial fistula were selected in Huzhou Hospital of Traditional Chinese Medicine Affiliated to Zhejiang University of Traditional Chinese Medicine from January to December in 2022 as the observation samples using convenience sampling method. They were divided into the experimental group and the control group with 45 cases in each group by the method of random number table. The control group used the conventional nursing care for maintenance haemodialysis endocardial fistula to administer nursing care, the experimental group introduced the micro-video breakthrough education and thematic workshop as a combined mechanism of intervention. The self-care behaviors with arteriovenous fistula and other observation indexes between the two groups were compared.Results:There were 23 males and 22 females in the control group, aged (58.07 ± 3.00) years old. There were 24 males and 21 females in the experimental group, aged (58.93 ± 4.07) years old. After care, the total internal fistula self-care behaviour score in the experimental group was (49.44 ± 1.84) points, and (38.93 ± 2.19) points in the control group, the difference between the two groups were statistical significant ( t = 24.65, P<0.05). For health management adherence, the score of fluid intake, dialysis regimen, medication and dietary dimension were (15.82 ± 1.37), (12.87 ± 1.39), (17.24 ± 1.33) and (21.60 ± 1.03) points in the experimental group, and (11.20 ± 0.92), (9.98 ± 1.14), (12.11 ± 1.01) and (17.40 ± 1.10) points in the control group, the difference between the two groups were statistical significant ( t values were 10.78 to 20.62, all P<0.05). For positive psychological capital, the scores of self-efficacy, resilience, hope and optimism were (38.69 ± 1.22), (39.27 ± 1.10), (33.29 ± 1.52) and (33.40 ± 1.39) points, and were (31.16 ± 1.26), (31.04 ± 1.15), ( 26.13 ± 1.52) and (27.09 ± 7.28) points in the control group, the difference between the two groups were statistical significant ( t values were 5.71 to 34.77, all P<0.05). The total complication rate of the experimental group was 8.89% (4/45), lower than 28.89% (13/45) in the control group, and the differences were all statistically significant ( χ2 = 5.87, P<0.05).

ABSTRACT

ABSTRACT The development of hemodialysis (HD) membranes has substantially advanced in the last decade. This has resulted in the manufacturing of medium cut-off membranes (MCO) whose internal architecture is based on greater pore size and a smaller diameter, thus promoting the clearance of particles of greater size as well as retrofiltration. Multiple studies have proven their efficacy in the clearance of uremic mid-sized molecules such as β2-microglobulin, free light chains, and some interleukins; this clearance is far superior with MCO membranes when compared with high-flux HD, and similar to that obtained with online hemodiafiltration. This review summarizes the results of the most relevant clinical studies of this membrane in terms of uremic toxin clearance, as well as the features of some clinical outcomes such as quality of life and hospitalizations.

ABSTRACT

Background: Several studies have suggested that online hemodiafiltration (OL-HDF) may reduce the risk of mortality and improve quality of life of these patients compared with standard hemodialysis. Methods: Forty stable out patients on dialysis (20 patients on hemodialysis and 20 patients on online hemodiafiltration) above age of 18 years and dialysis vintage of more than 3 months were followed up for 18 months. Clinical, biochemical parameters of these patients along with the SF-36 score at baseline and after 18 months of follow up were assessed. Results: At 18 months, statistically significant difference was found between hemodialysis (HD) and OL- HDF groups in erythropoietin dose (p=0.047), urea reduction ratio (p=0.016), Kt/V (p=0.005), hemoglobin (p=0.043), serum albumin (p=0.002), phosphorus (p=0.024), parathyroid hormone (p=0.007), potassium (p=0.007), ?2 microglobulin (p=0.002), high sensitive c-reactive protein (p=0.037), and serum bicarbonate levels (p=0.022). We found statistically significant difference in intradialytic complications namely intradialytic hypotension, muscle cramps, simultaneous hypotension and muscle cramps and stoppage of dialysis. In terms of mortality, the difference was not statistically significant (p=0.052). Conclusions: Patients on OL- HDF were having better quality of life than patients on HD. Better solute clearance, anemia control, improved nutritional and Mineral bone disorder parameters were seen in OL-HDF. Less complications during dialysis were seen with OL-HDF. The difference in mortality rate between the HD group and OL- HDF group was not statistically significant.

ABSTRACT

Objective:To evaluate the therapeutic effect of hemopurification on acute chlorfenapyr poisoning according to the blood concentration of chlorfenapyr and to provide experience for clinical treatment.Methods:Two patients who presented to our Emergency Department following an ingestion of chlorfenapyr and then were treated with hemopurification in 2022 were included. The concentrations of chlorfenapyr and its highly toxic metabolite tralopyril were dynamically monitored, and the clinical data of the patients were collected.Results:Case 1 was given hemoperfusion for the first time 13 hours after ingestion. During l hour hemoperfusion, the tralopyril decreased by 28.82%. The concentration increased and exceeded the pre-perfusion level after 2 hours of hemoperfusion. After three times of hemoperfusion, the concentrations of chlorfenapyr and tralopyril were still higher than those before the first time, reaching 248 ng/mL and 1 307 ng/mL respectively. The concentration of chlorfenapyr showed a downward trend after 130 h, and the tralopyril in blood reached the peak 3 164 ng/mL at 130 h and decreased to 2 707 ng/mL at 178 h. In case 2, the blood chlorfenapyr and tralopyril concentration was 392 ng/mL and 7 598 ng/mL respectively 150 hours after ingestion. The blood chlorfenapyr concentration decreased by 37.75% respectively after first hemoperfusion, and the tralopyril concentration decreased by 38.02% respectively. During 85 hours of continuous veno-venous hemodiafiltration (CVVHDF), the concentration of tralopyril was maintained at 4 234~6 410 ng/mL. Case 1 was followed up to 12 days and lost follow-up. Case 2 died and the survival time was 247 hours.Conclusions:Hemoperfusion can scavenge tralopyril, but CVVHDF has poor scavenging ability for tralopyril. And the apparent volume of distribution (Vd) of chlorfenapyr and tralopyril are large. After ingestion, chlorfenapyr spreads to various tissues quickly, and it is easy to accumulate in the adipose tissue. The chlorfenapyr in the tissue slowly is released back to the blood and stays in the blood for a long time. The peak concentration of chlorfenapyr appeared earlier than that of tralopyril. Clinicians should pay attention to the early removal of toxins from the digestive tract.

ABSTRACT

Objective:To investigate the effects of different blood purification methods on their nutritional status and inflammatory response in elderly patients with chronic renal failure.Methods:A total of 120 elderly patients with chronic renal failure who were treated in Lishui People′s Hospital from January 2020 to January 2022 were selected as the research objects, and they were divided into the control group and the observation group according to the random number table method, with 60 cases in each group. The patients in the control group were given hemodialysis alone, and the patients in the observation group were given hemofiltration dialysis treatment on the basis of the patients in the control group. The nutritional status-related indicators, inflammation-related indicators and renal function-related indicators before and after treatment were compared between the two groups.Results:After treatment, the levels of serum total protein (TP), albumin (ALB), hemoglobin (HGB) and creatinine clearance (Ccr) in the observation group were significantly higher than those in the control group: (65.61 ± 4.82) g/L vs. (61.26 ± 3.51) g/L, (36.54 ± 4.52) g/L vs. (31.53 ± 3.32) g/L, (97.58 ± 5.84) g/L vs. (93.06 ± 5.17) g/L, (41.88 ± 4.87) ml/min vs. (34.51 ± 4.36) ml/min, while the levels of interleukin-6 (IL-6), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), creatinine (Cr) and blood urea nitrogen (BUN) were significantly lower than those in control group: (120.09 ± 9.36) ng/L vs. (157.17 ± 14.27) ng/L, (7.15 ± 1.16) mg/L vs. (14.17 ± 2.74) mg/L, (22.14 ± 6.67) ng/L vs. (33.87 ± 7.28) ng/L, (327.16 ± 44.35) μmol/L vs. (378.59 ± 48.27), (10.15 ± 2.03) mmol/L vs. (15.83 ± 3.31) mmol/L, there were statistical differences ( P<0.05). Conclusions:For elderly patients with chronic renal failure, the use of hybrid blood purification can significantly reduce toxins in the body and improve the nutritional status and inflammation of patients, which is worthy of clinical promotion.

ABSTRACT

Objective:To explore the risk factors and prevention strategies for autologous arteriovenous fistula failure in 120 maintenance hemodialysis (MHD) patients, and build a regression model.Methods:The clinical data of 120 patients received MHD treatment in Anji County People′s Hospital from January 2020 to February 2022 were retrospectively analyzed, and the selected patients were divided into the failure group (25 cases) and the patency group (95 cases) according to whether they had autologous arteriovenous fistula failure. The clinical data of the two groups were compared. Multivariate Logistic regression analysis method was used to analyze the risk factors of autologous arteriovenous fistula failure in MHD patients. And a Logistic regression model was established to analyze the predictive value.Results:The proportions of women, diabetes and temporary catheter dialysis patients in the failure group were higher than those in the patency group: 56.00% (14/25) vs. 33.68% (32/95), 44.00% (11/25) vs. 13.68% (13/95), 92.00% (23/25) vs. 65.26% (62/95); the time of catheterization, plasma parathyroid hormone, serum albumin (Alb), D-Dimer (D-D), fibrinogen (FIB) and phosphorus were higher than those in the patency group: (47.87 ± 18.43) d vs. (39.65 ± 16.58) d, (439.76 ± 23.45) ng/L vs. (354.54 ± 31.26) ng/L, (43.43 ± 2.54) g/L vs. (39.65 ± 2.31) g/L, (1.13 ± 0.32) mg/L vs. (0.23 ± 0.07) mg/L, (5.64 ± 2.14) g/L vs. (2.76 ± 0.76) g/L, (3.54 ± 1.02) mmol/L vs. (0.76 ± 0.05) mmol/L( P<0.05). The results of multivariate Logistic regression analysis showed that female, concomitant diabetes, temporary catheter dialysis, and high level of serum phosphorus were independent risk factors for autologous arteriovenous fistula failure in MHD patients ( OR = 2.654, 3.077, 3.721, 2.646; P<0.05). Regression equation model was: logit( P) = -12.763 + sex × 0.976 + diabetes × 1.124 + temporary catheter dialysis × 1.314 + level of blood phosphorus × 0.973. When Logistic ( P) > 18.542, the area under the curve (AUC) value for autologous arteriovenous fistula failure prediction in this model was 0.882 (95% CI from 0.811 to 0.934), and with sensitivity of 80.00%, and specificity of 83.16%. Conclusions:Female gender, diabetes mellitus, temporary catheter dialysis, and high blood phosphorus level were independent risk factors for autologous arteriovenous fistula failure in patients with MHD. The model had a good predictive value for failure of autologous arteriovenous fistula in patients with MHD. Corresponding treatment and intervention measures could be used for patients with the above conditions in order to reduce the risk of autologous arteriovenous fistula failure and improve the treatment effect.

ABSTRACT

Objective:To investigate the correlation between serum Vitamin D, uric acid levels and arterial calcification in maintenance hemodialysis patients.Methods:A total of 120 patients who received MHD treatment in Daxing Teaching Hospital, Capital Medical University, from March 2019 to March 2021 were retrospectively selected as research subjects, and their general clinical data were recorded in detail. X-ray was used to detect the arterial calcification of patients. Multivariate Logistic regression was used to analyze the risk factors of arterial calcification in MHD patients.Results:According to the arterial calcification score, 120 MHD patients were divided into non-calcification group (43 cases, 35.83%), mild calcification group (16 cases, 13.33%), moderate calcification group (42 cases, 35.00%) and severe calcification group (19 cases, 15.83%). There were significant differences in dialysis years, serum Vitamin D, serum uric acid, serum calcium, serum phosphorus, intact parathyroid hormone (iPTH) and arterial calcification score among the four groups ( P<0.05). According to serum Vitamin D level, 120 MHD patients were divided into deficient serum Vitamin D group (84 cases, 70.00%) and normal serum Vitamin D group (36 cases, 30.00%), serum calcium and phosphorus levels in the deficient serum Vitamin D group were lower than those in the normal serum Vitamin D group: (2.53 ± 0.28) mmol/L vs. (3.15 ± 0.31) mmol/L, (1.83 ± 0.26) mmol/L vs.(2.07 ± 0.31) mmol/L; serum uric acid and arterial calcification scores in the deficient serum Vitamin D group were higher than those in the normal serum Vitamin D group: (512.41 ± 65.21) μmol/L vs.(311.94 ± 72.56) μmol/L, (6.92 ± 2.34) scores vs. (2.18 ± 2.01) scores, there were statistical differences ( P<0.05). One hundred and twenty MHD patients were divided into hyperuricemia group (77 cases, 64.17%) and uric acid normal group (43 cases, 35.83%) according to the level of serum uric acid, the serum Vitamin D level in the hyperuricemia group was lower than that in uric acid the normal group: (12.28 ± 5.18) μg/L vs. (28.84 ± 4.69) μg/L; and iPTH level and arterial calcification scores were higher than those in the uric acid normal group: (372.45 ± 90.31) ng/L vs. (291.60 ± 98.52) ng/L, (6.22 ± 2.52) scores vs. (2.72 ± 2.63) scores, there were statistical differences ( P<0.05). The results of multivariate Logistic regression showed that serum Vitamin D and uric acid levels were risk factors for arterial calcification in MHD patients ( P<0.05). Conclusions:Serum Vitamin D and uric acid levels are correlated with arterial calcification in MHD patients, and are the risk factors leading to arterial calcification in patients.

ABSTRACT

Objective:To report a case of acute kidney injury caused by rhabdomyolysis and summarize its etiology, pathogenesis, and treatment strategy.Methods:The clinical data of a case of rhabdomyolysis complicated by acute kidney injury admitted to Affiliated Huadu Hospital of Southern Medical University on August 30, 2020, were collected, including clinical manifestation, auxiliary examination, and disease outcome. Referring to the previous literature reports of rhabdomyolysis complicated by acute kidney injury, this paper discusses its etiology, monitors and analyzes some indicators such as serum creatinine, blood urea nitrogen, creatine kinase, myoglobin, and 24-hour urine volume during the treatment, and summarizes the clinical diagnosis and treatment ideas of the disease.Results:This case developed an intestinal infection after an unclean diet, which induced rhabdomyolysis and acute kidney injury. Renal pathology after renal biopsy showed that renal biopsy result was consistent with an acute tubulointerstitial injury caused by myoglobin tubular nephropathy. The biochemical indexes such as creatine kinase and myoglobin decreased rapidly after ordinary hemodialysis, but the levels of serum creatinine and blood urea nitrogen did not decrease markedly, and there was continuous oliguria. After switching to hemodialysis filtration and continuous intensive dialysis treatment, the levels of serum creatinine and blood urea nitrogen decreased rapidly, the amount of urine increased gradually, and finally, the renal function recovered.Conclusion:For acute kidney injury caused by rhabdomyolysis, early sufficient blood purification can accelerate the clearance of myoglobin, promote the recovery of the injured kidney, and improve the prognosis of the disease.

ABSTRACT

Objective:To investigate the clinical effect of Shenqi Dihuang Decoction and Xiaochengqi Decoction enema combined with hemodialysis in the treatment of qi deficiency, blood stasis and dampness and turbidity in chronic kidney disease (CKD) stage 5.Methods:Randomized controlled trial. A total of 102 elderly CKD stage 5 patients with Qi and Yin deficiency and turbid poison inherent type were selected from May 2021 to January 2022 of the Beijing Longfu Hospital. The patients were divided into two groups by random number table method. Control group (51 cases) received hemodialysis treatment for 4 weeks, and the observation group (51 cases) received Shenqi Dihuang Decoction and Xiaochengqi Decoction enema combined with hemodialysis treatment for 4 weeks. The levels of BUN, SCr and β2-microglobulin (β2-MG), and K +, Ca 2+, P 3- content, hemoglobin were detected by automatic blood cell analyzer, and serum CRP and IL-6 levels were detected by latex enhanced immune scattering turbidimetry. The adverse reactions during the treatment and evaluate the clinical efficacy were observed and recorded. Results:During the treatment, 2 patients in the observation group withdrew from the study due to severe diarrhea, and other patients completed the study. There were significant differences in total response rate between observation group and control group [91.84%(45/49) vs. 74.51%(38/51); χ2=5.32, P=0.002]. After treatment, scores of lumbar and knee acerbity, tiredness and fatigue, edema, dizziness and tinnitus, fear of cold and warm, yellow face, dry stool and total score in observation group were significantly lower than those in the control group ( t=8.38, 13.44, 15.14, 13.09, 7.12, 7.73, 11.16, 11.45, P<0.01); the scores of SF-12-PCS and SF-12-MCS were significantly higher than those in the control group ( t=3.24, 4.22, P<0.01). After treatment, levels of serum BUN [(15.02±2.35)mmoL/L vs. (18.02±3.65)mmoL/L, t=4.87], SCr[(155.26±23.65) μmol/L vs. (184.49±35.49) μmol/L, t=4.83], β2-MG[(7.12±1.27)mg/L vs. (9.56±2.14)mg/L, t=6.90] and P 3-[(1.51±0.10) mmol/L vs. (2.02±0.19) mmol/L, t=16.70], K +[(3.65±0.54) mmol/L vs. (4.21±0.63)mmol/L, t=4.76] in observation group were significantly lower than those in the control group ( P<0.01); Ca 2+[(1.86±0.36)mmol/L vs. (2.35±0.42)mmol/L, t=6.25] was significantly higher than that of the control group ( P<0.01). No adverse reactions occurred during the treatment in the two groups ( P>0.05). Conclusion:Shenqi Dihuang Decoction and Xiaochengqi Decoction enema and hemodialysis can improve renal function, correct electrolyte disorder, reduce the level of inflammatory factors, improve the quality of life, and improve the therapeutic effect of the patients with CKD stage 5 and Qi and Yin deficiency and turbid poison inherent pattern.

ABSTRACT

Objective:To investigate the effect of maintenance hemodialysis (MHD) combined with levocarnitine on vascular sclerosis and vascular endothelial function in patients with chronic renal failure.Methods:Patients with chronic renal failure receiving MHD treatment admitted to Shanxian Central Hospital of Shandong Province from June 2019 to May 2020 were selected as the research object and they were divided into the observation group (53 cases) and the control group (49 cases) by the random number table method. The patients in the control group were treated with maintenance hemodialysis and the patients in the observation group were treated with combined levocarnitine on the basis of the control group. The levels of serum creatinine (SCr), blood urea nitrogen (BUN) and other renal function indicators were determined before and 6 months after the treatment. The levels of nuclear factor kappa B (NF-κB), tumor necrosis factor (TNF-α) and other microinflammatory indexes, and advanced oxidation protein products (AOPP), malondialdehyde (MDA), glutathione peroxidase (GSH-Px) and other oxidative response indexes were determined. The levels of endothelin-1 (ET-1), von Willebrand factor (vWF) and vascular reactive hyperemia index (RHI) were measured. Common carotid atherosclerosis β and pulse wave conduction velocity (PWV) were measured by color Doppler ultrasonography.Results:The levels of SCr, BUN in the two groups after treatment had no significant differences ( P>0.05). The levels of TNF-α and NF-κB in the observation group after treatment were lower than those in the control group: (20.22 ± 7.15) μg/L vs.(26.14 ± 5.96) μg/L, (6.10 ± 0.80) mg/L vs. (6.55 ± 1.10) mg/L, there were statistical differences ( P<0.05). The levels of AOPP, MDA in the observation group after treatment were lower than those in the control group and the level of GSH-PX was higher than that in the control group: (78.52 ± 17.41)μmol/L vs.(97.96 ± 18.29) μmol/L, (4.44 ± 1.02) μmol/L vs. (6.07 ± 1.26) μmol/L, (110.14 ± 22.17) mg/L vs.(90.63 ± 19.28) mg/L, there were statistical differences ( P<0.05). The levels of PWV, ET-1 and vWF in the observation group after treatment were lower than those in the control group and the RHI was higher than that in the control group: (7.29 ± 0.59) m/s vs. (7.89 ± 0.63) m/s, (44.15 ± 10.27) ng/L vs. (52.41 ± 12.74) ng/L, (30.26 ± 7.45) U/L vs. (35.71 ± 6.23) U/L, 1.54 ± 0.25 vs. 1.45 ± 0.20, there were statistical differences ( P<0.05). Conclusions:The combination of levocarnitine in the treatment of MHD can alleviate microinflammation, oxidative stress response and improve vascular endothelial function and arteriosclerosis.

ABSTRACT

ABSTRACT Online hemodiafiltration is potentially a superior mode of dialysis compared to conventional hemodialysis. However, prospective randomized controlled trials have failed to demonstrate such superiority. Post-hoc analyses of these trials have indicated that high volume post-dilution hemodiafiltration is associated with lower death rates than conventional dialysis. This study discusses whether the lower death rates ascribed to high volume hemodiafiltration are linked to convection volume or the time on dialysis needed to achieve high convection volumes.


RESUMO A hemodiafiltração on-line é uma modalidade de diálise com potencial de superioridade sobre a hemodiálise convencional. Entretanto, estudos prospectivos, randomizados e controlados falharam em demonstrar a superioridade da hemodiafiltração. Análises post hoc desses estudos sugerem que a hemodiafiltração pós-dilucional de alto volume apresenta taxa de mortalidade inferior à hemodiálise convencional. Neste estudo, discutimos se a menor taxa de mortalidade da hemodiafiltração de alto volume está associada ao volume de convecção ou ao tempo de diálise necessário para atingir um alto volume de convecção.

INTRODUCTION. The incorporation of new technologies such as online haemodiafiltration have improved metabolic/nutritional parameters in patients who were on conventional haemodialysis; At present, there are no registered data on the Ecuadorian population that is subjected to this kind of technology. OBJECTIVE. To compare the clinical-metabolic evolution of patients who were on conventional hemodialysis and changed to online hemodiafiltration, to determine if the migration from diffusive to convective hemodialysis therapy is favorable and to establish if the change in dialysis therapy caused favorable results. MATERIALS AND METHODS. Retrospective analytical study. Population and sample of 38 patients with chronic kidney disease in conventional hemodialysis modality renal replacement therapy who changed to online hemodiafiltration, regardless of the time of diagnosis and treatment in the hemodialysis unit of the Hospital de Especialidades Carlos Andrade Marín, Quito-Ecuador, during the period March 2016 to March 2017. RESULTS. The nutritional and metabolic effects could denote a greater weighting of favorable results in the hemodiafiltration modality. In hemodynamic stability and dialysis dose, a slight superiority was evidenced in the hemodiafiltration modality compared to hemodialysis. In the administered doses of Calcium, Iron, Erythropoietin and Calcitriol there were no significant differences between the two treatment modalities. CONCLUSION. The change of modality from conventional hemodialysis to online hemodiafiltration was favorable, and improved the clinical/metabolic parameters of patients requiring renal replacement therapy.

ABSTRACT

Objective:To investigate the effects of high-flux versus low-flux hemodialysis on end-stage renal disease in older adults and evaluate its effects on myocardial injury indexes and micro-inflammatory response indexes. Methods:Seventy-two patients with ESRD who received treatment in Affiliated Hospital of Shaoxing University from January 2019 to January 2020 were included in this study. They were randomly assigned to receive either low-flux hemodialysis (control group, n = 36) or high-flux hemodialysis (observation group, n = 36). All patients received 6 months of treatment. Micro-inflammatory response indexes and renal function indexes pre- and post-treatment, and reverse reactions were observed in each group. Results:Serum interleukin-6, tumor necrosis factor α, and high-sensitivity C-reactive protein levels post-treatment in the observation group were (7.16 ± 1.32) ng/L, (2.10 ± 0.36) pg/L, (2.20 ± 1.06) mg/L respectively, which were significantly lower than those in the control group [(10.45 ± 1.42) ng/L, (5.22 ± 0.65) pg/L, (3.84 ± 1.57) mg/L, t = 10.19, 25.19, 5.19, all P < 0.001]. Serum parathyroid hormone, B-type natriuretic peptide, and cardiac troponin T levels post-treatment in the observation group were (520.36 ± 95.65) pmol/L, (0.45 ± 0.10) μg/L, (15.05 ± 6.37) ng/L, respectively, which were significantly lower than those in the control group [(830.25 ± 102.35) pmol/L, (0.85 ± 0.13) μg/L, (30.25 ± 6.59) ng/L, t = 13.27, 14.63, 9.95, all P < 0.001]. The total response rate was significantly higher in the observation group than in the control group [75.00% (27/36) vs. 47.22% (19/36), χ2 = 3.85, P < 0.05]. The overall incidence of adverse reactions was significantly lower in the observation group than in the control group [19.44% (7/36) vs. 41.67% (15/36), χ2 = 4.18, P < 0.05). Conclusion:High-flux hemodialysis can highly improve the control effect of micro-inflammatory responses and alleviate myocardial injury in older adult patients with end-stage renal disease. High-flux hemodialysis is more effective and safer than low-flux hemodialysis.

ABSTRACT

Objective:To explore the effects of different blood purification modes on short-term complications, quality of life and survival prognosis of patients with uremia.Methods:The patients with uremia who received hemodialysis treatment at two blood purification centers in the First Affiliated Hospital of Dalian Medical University and Renal Care Hospital from January 1, 2017 to December 1, 2019 were enrolled in this study. According to the different blood purification modes, the patients were divided into high-flux hemodialysis (HFHD) group (HFHD group), HFHD+hemodiafiltration (HDF) per month group (HDF once a month group) and HFHD+HDF per week group (HDF once a week group). The three groups were matched with the ratio of 1∶1∶1 on the duration of hemodialysis based on the HDF once a week group. The differences of clinical indicators, medication and rehospitalization between baseline and end points were compared. The patients were followed up to 12 months after enrolled in the study or death. Patients in each group were divided into two subgroups, newly imported group and non-newly imported group based on whether or not they were newly enrolled in HD therapy from January 1, 2017 to December 1, 2019. Kaplan-Meier survival curve and Cox regression model were used to analyze the difference of survival prognosis in non-newly imported patients with different dialysis modes, and the EuroQol-5 Dimensions (EQ-5D-5L) was used to evaluate the difference of quality of life in newly imported patients after different dialysis modes treatment.Results:A total of 139 patients were enrolled, including 43 cases in the HFHD group, 47 cases in the HDF once a month group, and 49 cases in the HDF once a week group. After treatment, the levels of serum creatinine, serum urea nitrogen and serum potassium in the HDF once a week group were significantly lower than those in the other two groups (both P<0.05). Compared with the other two groups, the consumptions of erythropoietin and intravenous iron, the hospitalization times and hospitalization days in the HDF once a week group were significantly decreased, and the level of albumin in the HDF once a week group were significantly increased (all P<0.05). Kaplan-Meier survival curve analysis of non-newly imported hemodialysis patients showed that the survival rate in the HDF once a week group was higher than that in the other two groups (Log-rank χ2=7.020, P=0.030). Multivariate Cox regression analysis showed that HDF was a protective factor for post-dialysis survival in uremia patients ( HR=0.472, 95% CI 0.188-0.836, P=0.023). The total efficacy of EQ-5D-5L of the newly imported patients in the HDF once a week group was significantly higher than that in the other two groups ( F=7.293, P=0.002). Conclusions:The combination of HFHD with HDF per week therapy can significantly improve the short-term quality of life and nutritional status, and reduce the hospitalization frequency, length of hospital stay, the consumption of erythropoietin and intravenous iron and mortality risk in uremia patients.

ABSTRACT

Objective:To explore the correlation between plasma sclerostin (SOST) and bone turnover markers and inflammatory factors in hemodialysis patients.Methods:One hundred and eight patients admitted to Changsha Central Hospital Affiliated to Nanhua University from January 2018 to May 2019 were selected. The levels of plasma SOST at admission and at 3, 6 and 12 months of dialysis were determined by enzyme-linked immunosorbent assay. They were divided into low- SOSTgroup (56 cases) and high- SOSTgroup (52 cases) based on the mean value of SOST. The levels of serum bone turnover markers β-Ⅰ collagen carboxy-terminal peptide (β-CTX) and osteocalcin (OC), propeptide of type Ⅰ procollagen (PINP), full parathyroid hormone (iPTH), N-terminal osteocalcin (N-MID-OC), inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) were compared between the two groups, abdominal aortic calcification (ACC) score was performed, and Pearson linear correlation analysis was used to analyze the relationship between SOST level of hemodialysis patients and bone turnover markers, inflammatory factors and ACC scores.Results:The baseline levels of β-CTX, OC, PINP, iPTH, and N-MID-OC in the low- SOST group were higher than those in the high- SOST group: (976.03 ± 205.27) ng/L vs. (781.34 ± 150.45) ng/L, (175.31 ± 50.49) ng/L vs. (125.75 ± 40.17) ng/L, (321.45 ± 82.14) μg/L vs. (259.41 ± 75.36) μg/L, (345.26 ± 102.65) ng/L vs. (198.52 ± 45.71) ng/L, (19.96 ± 5.01) μg/L vs. (17.41 ± 4.23) μg/L, the differences were statistically significant ( P<0.05). The baseline levels of IL-1β, IL-6, CRP, TNF-α and ACC scores in the low- SOST group were higher than those in the high- SOST group: (19.31 ± 6.01) ng/L vs. (15.23 ± 4.75) ng/L, (76.85 ± 20.34) ng/L vs. (57.98 ± 15.02) ng/L, (8.15 ± 2.36) mg/L vs. (7.23 ± 1.79) mg/L, (178.37 ± 55.52) ng/L vs. (157.42 ± 10.15) ng/L, (5.96 ± 1.78) scores vs. (5.11 ± 1.15) scores, the differences were statistically significant ( P<0.05). After treated for 3, 6 and 12 months, the levels of β-CTX, OC, PINP, iPTH, N-MIC-OC in hemodialysis patients were increased, the level of SOST was decreased, the levels of IL-1β, IL-6, CRP, TNF-α increased and ACC scores were increased, the differences were statistically significant ( P<0.05). The Pearson linear correlation analysis showed that SOST level and bone turnover markers β-CTX ( r = -0.465, P<0.001), OC( r = -0.498, P<0.001), PINP( r = -0.511, P<0.001), iPTH ( r = -0.396, P = 0.012), N-MID -OC ( r = -0.323, P = 0.031) and inflammatory factors IL-1β( r = -0.305, P = 0.046), IL-6( r = -0.318, P = 0.041), CRP( r = -0.327, P = 0.034) and TNF-α( r = -0.378, P = 0.024) in hemodialysis patients were negatively correlated, and negatively correlated with abdominal aortic calcification scores ( r = -0.301, P = 0.048). Conclusions:Plasma SOST level in hemodialysis patients is lower, which is negatively correlated with bone turnover markers, inflammatory factors, and calcification scores. Low SOST level can induce vascular calcification by mediating bone metabolism disorders and aggravating the body′s inflammatory response, and increase the risk of hemodialysis vascular calcification.
