Progress of high-flux hemodialysis in clinical application, complications and treatment

Hemodialysis is the main method of clinical renal replacement therapy, and its effectiveness and safety have been widely confirmed. High-flux hemodialysis, as a constantly updating new mode in the field of blood purification, has effectively improved the efficiency of hemodialysis and reduced the incidence of hemodialysis complications. High-flux hemodialysis has been widely used in clinical practice, and mainly plays its role through adsorption, convection and dispersion. High-flux hemodialysis has some advantages not possessed by conventional hemodialysis, including protecting injured renal function, reducing the incidence of cardiovascular complications in hemodialysis patients, improving the patients' nutritional status, reducing the occurrence of renal osteopathy and delaying the occurrence time of dialysis-associated amyloidosis. However, high-flux hemodialysis also has some limitations, such as the elimination of drugs and nutrients, and the backfiltration caused by increased pressure on the dialysis membrane and dialysate side. In this review, the related progress of high-flux hemodialysis in clinical application, mechanism, complications and treatment are discussed in order to provide a reference for its more rational clinical use.

Effects of High-Flux Hemodialysis on Inflammatory Factors and Nutritional Status in Patients with Severe Renal Failure

Objective:To investigate the effects of high-flux hemodialysis on inflammatory factors and nutritional status in patients with severe renal failure.Methods:A total of 72 patients with severe renal failure who underwent dialysis treatment in the hospital from January 2017 to March 2019 were selected as the research subjects,and they were randomly divided into 2 groups with 36 patients each.The control group underwent low-flux hemodialysis,and the observation group underwent high-flux hemodialysis.The levels of inflammatory factors and nutritional status were compared between the two groups after treatment.Results:The levels of various inflammatory factors in the observation group were lower than those in the control group and the nutritional indexes were higher than those in the control group after 4 weeks of treatment(P<0.05).Conclusion:High-throughput hemodialysis in patients with severe renal failure can significantly reduce the levels of inflammatory factors and improve nutritional status.

Effects of high-flux hemodialysis on plasma adrenomedullin and sustained hypotension in elderly hemodialysis patients

Background Sustained hypotension during hemodialysis （HD） is an important clinical issue. Plasma adrenomedullin （AM） is increased in HD patients with sustained hypotension, but little is known about whether removing AM can improve hypotension. The objective of this study was to investigate the beneficial effects of hemodialysis using a high-flux dialyzer on removal of increased plasma AM levels and improving low blood pressure in elderly HD patients with sustained hypotension.Methods Forty-eight elderly patients （age 65 or older） who had undergone maintenance HD for more than one year were recruited and studied. We evaluated plasma levels of AM in sustained hypotension （SH; n=28） and normotensive （NT; n=20） patients. The patients with hypotension were further divided into two subgroups and treated with eitherhigh-flux dialyzer or low-flux dialyzer for 3 months. Plasma adrenomedullin levels and blood pressure were analyzed at days 0 and 181.Results Plasma levels of AM were significantly higher in SH than in NT patients （（24.92±3.7） ng/L vs. （15.52±6.01） ng/L,P〈0.05）, and were inversely correlated with mean arterial blood pressure （MAP） at pre-HD. After 3 months, the level of plasma AM in high-flux group was decreased （（24.58±4.36） ng/L vs. （16.18±5.08） ng/L, P 〈0.05）, but MAP was increased （（67.37±4.31） mmHg vs. （74.79±3.59） mmHg, P〈0.05）. There was no obvious change in low-flux group.Conclusions Plasma AM levels were significantly elevated in elderly HD patients with SH. High-flux dialyzer therapy can decrease plasma AM level and improve hypotension.

Refining safety considerations for intradialytic blood flow restriction exercise. Commentary on “Concerns on the application of blood-flow restriction resistance exercise and thrombosis risk in hemodialysis patients”

High-resolution neutronics model for ^(238)Pu production in high-flux reactors

We proposed and compared three methods(filter burnup,single energy burnup,and burnup extremum analysis)to build a high-resolution neutronics model for 238Pu production in high-flux reactors.The filter burnup and single energy burnup methods have no theoretical approximation and can achieve a spectrum resolution of up to~1 eV,thereby constructing the importance curve and yield curve of the full energy range.The burnup extreme analysis method combines the importance and yield curves to consider the influence of irradiation time on production efficiency,thereby constructing extreme curves.The three curves,which quantify the transmutation rate of the nuclei in each energy region,are of physical significance because they have similar distributions.A high-resolution neutronics model for ^(238)Pu production was established based on these three curves,and its universality and feasibility were proven.The neutronics model can guide the neutron spectrum optimization and improve the yield of ^(238)Pu by up to 18.81%.The neutronics model revealed the law of nuclei transmutation in all energy regions with high spectrum resolution,thus providing theoretical support for high-flux reactor design and irradiation production of ^(238)Pu.

Concerns about the application of resistance exercise with blood-flow restriction and thrombosis risk in hemodialysis patients

Background:Hemodialysis(HD) per se is a risk factor for thrombosis.Considering the growing body of evidence on blood-flow restriction(BFR) exercise in HD patients,identification of possible risk factors related to the prothrombotic agent D-dimer is required for the safety and feasibility of this training model.The aim of the present study was to identify risk factors associated with higher D-dimer levels and to determine the acute effect of resistance exercise(RE) with BFR on this molecule.Methods:Two hundred and six HD patients volunteered for this study(all with a glomerular filtration rate of <15 mL/min/1.73 m2).The RE+BFR session consisted of 50% arterial occlusion pressure during 50 min sessions of HD(intradialytic exercise).RE repetitions included concentric and eccentric lifting phases(each lasting 2 s) and were supervised by a strength and conditioning specialist.Results:Several variables were associated with elevated levels of D-dimer,including higher blood glucose,citrate use,recent cardiovascular events,recent intercurrents,higher inflammatory status,catheter as vascular access,older patients(>70 years old),and HD vintage.Furthermore,RE+BFR significantly increases D-dimer after 4 h.Patients with borderline baseline D-dimer levels(400-490 ng/mL) displayed increased risk of elevating D-dimer over the normal range(≥500 ng/mL).Conclusion:These results identified factors associated with a heightened prothrombotic state and may assist in the screening process for HD patients who wish to undergo RE+BFR.D-dimer and/or other fibrinolysis factors should be assessed at baseline and throughout the protocol as a precautionary measure to maximize safety during RE+BFR.

Sleep quality in middle-aged and elderly hemodialysis patients:Impact of a structured nursing intervention program

BACKGROUND Poor sleep quality is common among hemodialysis patients and can significantly impact their well-being.This study aimed to evaluate the effectiveness of a structured nursing intervention program in improving sleep quality in middleaged and elderly hemodialysis patients.AIM To evaluate the impact of nursing intervention on sleep quality in hemodialysis patients.METHODS This cross-sectional study was conducted in a tertiary hospital,the First Affiliated Hospital of Nanchang University,in 2023.This study included 105 middle-aged and elderly hemodialysis patients aged≥45 years who underwent maintenance hemodialysis for at least 3 mo,utilizing the Pittsburgh Sleep Quality Index(PSQI)to identify poor sleepers.Those identified underwent a 12-wk nursing intervention program focusing on education,relaxation techniques,and counseling.Post-intervention,sleep quality was reassessed using the PSQI.RESULTS The study found that 68.6%of hemodialysis patients were poor sleepers.Following the 12-wk nursing intervention program,there was a significant decrease in the mean global PSQI score from 8.9±3.2 to 5.1±2.7(P<0.001),indicating improved sleep quality.This demonstrated the effectiveness of the structured nursing intervention in enhancing sleep quality for middle-aged and elderly hemodialysis patients.CONCLUSION The structured nursing intervention program focusing on sleep hygiene education,relaxation techniques,and counseling effectively improved sleep quality among middle-aged and elderly hemodialysis patients.The significant decrease in the mean global PSQI score post-intervention indicates the positive impact of tailored nursing interventions in addressing poor sleep quality in this patient population.These findings emphasize the importance of implementing targeted nursing interventions to enhance the quality of life for hemodialysis patients by addressing the prevalent issue of poor sleep quality.

Effect of high-flux and low-flux hemodialysis on the side metabolites and cytokines in patients with uremia

Objective:To study the effect of high-flux and low-flux hemodialysis on the side metabolites and cytokines in patients with uremia.Methods: A total of 50 patients with uremia who accepted high-flux hemodialysis and 140 patients with uremia who accepted low-flux hemodialysis in our hospital between March 2015 and March 2016 were selected and included in high-flux group and low-flux group respectively. Before and after dialysis, serum was collected respectively to determine the levels of side metabolites, calcium-phosphorus metabolism indexes and cytokines.Results: 3 months after dialysis, serum Ca levels of two groups of patients were not significantly different from those before dialysis while BUN, Scr,β2-MG, sTfR, P, PTH and AKP levels were significantly lower than those before dialysis;3 months after dialysis, serum BUN, Scr and Ca levels of high-flux group were not significantly different from those of low-flux group whileβ2-MG, sTfR, P, PTH, AKP, TNF-α, IL-1β, IL-6, IL-8 and IL-10 levels were significantly lower than those of low-flux group.Conclusion:Compared with low-flux hemodialysis, high-flux hemodialysis treatment of uremia can more effectively remove middle molecular and macromolecular toxins, correct calcium-phosphorus metabolism disorder and relieve micro-inflammatory state.

Ferritin and mortality in hemodialysis patients with COVID-19:A systematic review and meta-analysis

Objective:To investigate the difference in serum ferritin levels between deceased and surviving regular hemodialysis patients with COVID-19.Methods:We conducted a systematic search across four databases following the PRISMA statement guidelines.Studies reporting ferritin levels and mortality of regular hemodialysis patients with COVID-19 were included.Employing the random-effects model,we performed a meta-analysis to determine the mean difference in serum ferritin levels between the studied groups,along with their corresponding 95%confidence intervals.The meta-analysis was carried out using Review Manager 5.4 and Stata 16.Results:A total of 1013 patients from seven studies were included in this study.Our meta-analysis showed higher mean serum ferritin in the deceased compared to surviving regular hemodialysis patients with COVID-19,with a mean difference of 449.43 ng/mL[95%CI(244.07,654.80),P<0.0001;I2=58%,P=0.003].Conclusions:Our study found a higher mean of serum ferritin levels in the deceased compared to surviving regular hemodialysis patients with COVID-19.

Antioxidants Enzymes Activities and NO Levels in Hemodialysis and Continuous Ambulatory Peritoneal Dialysis—A Comparative Study

It consists of a retrospective study with twenty-two individuals diagnosed with DRC: fourteen HD and eight CAPD, followed up in the dialysis center of Antonio Pedro University Hospital (HUAP) of Fluminense Federal University (UFF), between 2015 and 2017. Fifteen healthy control (HC) subjects were included, without diagnosed CKD. Patients with HIV positive, hepatitis A, B, and C, pregnant, cancer, smokers, alcoholics and those exposed to X-rays in the last 3 months, were excluded. Objectives: As oxidative stress and endothelial dysfunction may be linked to the higher prevalence of CVD in CKD patients, we measured the activities of the antioxidants enzymes: SOD and GPx and total NO levels in the plasma and serum of end-stage CKD patients undergoing dialysis therapy, comparing with the HC group. Methods: Quantification of NO levels was performed by fluorometric kit, while activities of SOD and GPx were determined using kinetic methods. Results: We found higher plasma SOD activity in HD (8.58 U/ml) and CAPD (10.14 U/ml), compared to C (3.73 U/ml) group, while GPx activity was decreased in HD (115.38 nmol/h/ml) and CAPD (122.76 nmol/h/ml) groups compared to HC group (275.83 nmol/h/ml). Total serum NO concentration was decreased in HD (14.09 pmol/μl) and CAPD (10.26 pmol/μl), compared to non-CKD patients (49.65 pmol/μl). Conclusion: Decreased total serum NO and GPx activities may lead to endothelial dysfunction and consequently a higher prevalence of CVD in CKD patients.

Normal Range of Neutrophile to Lymphocyte Ratio in Healthy, Chronic Kidney Disease Stage 4 - 5 and Hemodialysis Participant in a Sub-Saharan African Context

Background: Neutrophile to lymphocyte ratio (NLR) is a well-established marker of inflammation. It has been reported to be high in chronic kidney disease (CKD) and it is described as a prognosis factor in hemodialysis patients. However, limited data are available about the normal range of NLR in healthy adults as well as CKD patients including hemodialysis black Africans in Sub-Saharan countries. We sought to study NLR in healthy and advanced CKD in a single Cameroonian health facility. Methods: Blood samples were obtained from blood donors, CKD stage 4 and non-dialysis stage 5, and hemodialysis patients for more than 6 months. Patients with confounding factors such as positive CRP, infection, and recent use of steroids were excluded. RNL means standard deviations (SDs), and 95% confidence intervals (95% CI) were determined. RNL range was defined as percentiles P2.5 to P97.5. Results: A total of 102 participants were included. Mean age was 40.45 ± 9.97 years and 58.8% were male. Age and sex distribution were similar in the three groups. Leucopenia and neutropenia were common in all the groups. Means NLR was 1.29 ± 0.57 (95% CI 1.08 - 1.49) range between 0.55 to 2.67;2.31 ± 1.3 (95% CI 1.75 - 2.88) with range between 0.69 to 4.31 and 2.14 ± 0.98 (95% CI 1.85 - 2.44) with range between 0.77 to 4.32 respectively in controls, CKD, and hemodialysis participants. NLR was comparable in CKD and hemodialysis patients (p = 0.99). Compared to controls, NLR was significantly elevated in CKD (p = 0.043) and hemodialysis patients (p Conclusion: Our data suggest that the normal range for NLR in adult nongeriatric healthy and advanced CKD patients including those on chronic hemodialysis may vary between 0.55 to 2.67 and 0.69 to 4.32 respectively.

Correlation between Wnt Signalling Inhibitors (Dickkopf-1 & Sclerostin) and the Intimal Medial Thickness in Children on Maintenance Hemodialysis

Background: Wnt signalling inhibitors (Dickkopf-1 and Sclerostin) signalling play a role in vascular development and may contribute to calcification. Aim: To investigate the association between Dickkopf-1 and sclerostin serum concentrations in children undergoing maintenance hemodialysis with intimal medial thickness and peak systolic velocity of the main arteries. Patients and Methods: A study was conducted on 40 children undergoing maintenance hemodialysis and controls of the same age and sex. The study measured the initial medial thickness (IMT) and peak systolic velocity (PSV) of the main vessels (carotid, ulnar, and femoral). Dickkopf-1 and sclerostin serum levels in both groups were assessed, and a routine investigation was performed. Results: The findings indicate that the levels of serum Dickkopf-1 and Sclerostin were significantly higher in the hemodialysis group 2540.65 (2215.4 - 2909.2 pg/ml) and 1.17 (0.85 - 2.03 ng/ml)respectively (P = 0.001), compared to their control group it was 1110.45 (885.45 - 1527.65 pg/ml) and 0.28 (0.25 - 0.32 ng/ml)) respectively P = 0.001. Additionally, there was a significant increase in intima-media thickness (IMT) with a decrease in peak systolic velocity (PSV) in the main blood vessels, including the carotid, ulnar, and femoral arteries. A significant correlation was also observed between Dickkopf-1 and sclerostin levels and IMT of the carotid, ulnar, and femoral arteries. Conclusion: Wnt signalling inhibitors (Dickkopf-1 and Sclerostin) exert effects beyond the bone and significantly contribute to early vascular calcification in pediatric patients undergoing maintenance hemodialysis.

A Look to Nursing Care Perceived by Adolescents in a Hemodialysis Unit

Background: Adolescent’s perception of nurse care imparted in the hemodialysis unit and the needs that they do not always express are an important starting point to optimize attention and care given by nurse professional;the goal is to reach the holistic focus characteristic of the discipline, and then generate scientific evidence that will help other health professionals, regarding given attention to patients in this step of their lives suffering chronic renal damage subjected to hemodialysis. Objective: To analyze the perception of adolescents with chronic kidney disease about nurse care in a hemodialysis unit. Methods: Qualitative and phenomenological study under the philosophic scope of Merleau Ponty, with a descriptive design;the information collection was through semi-structured interviews, field notes, and participants’ observation from three adolescents’ informers subjected to renal substitution by hemodialysis three times per week, in a high specialty medical unit in Mexico City. Selection of informers was by convenience and their previous authorization was requested by signed informed consent. The analysis of qualitative data was according to Rodríguez et al. Results: Four categories with seven subcategories emerged: Category 1, Adolescent’s perception regarding nursing care on hemodialysis;Category 2, Care during hemodialysis process;Category 3, The world of hemodialysis;Category 4, Corporeity from adolescent’s look. Conclusion: Nursing care to adolescents during hemodialysis must be accompanied by comprehension, communication, and knowledge of patients, regarding their needs perceived to know the way they live their chronic kidney illness, through their body, their world and the way they see themselves. The main characteristics of nurse care are communication and constant interaction with nurse-adolescent, this openness to an unknown world for them is seen as a pleasant interaction, perceived as necessary and it helps them to feel good in their hemodialysis treatment.

Humoral Response and Tolerance of Vaccination against SARS-CoV-2 in Adults Senegalese Patients Undergoing Hemodialysis: A Multicenter Prospective Study

Introduction: Following the COVID-19 pandemic, vaccination has been proposed in several countries as the main preventive measure despite very limited data, particularly in dialysis patients. We conducted this study to assess the immunological response to vaccination in Senegalese hemodialysis patients. Patients and Methods: We conducted a prospective study, in two dialysis centers in Dakar from March 30th to August 30th, 2021 including patients on hemodialysis for >6 months, vaccinated against SARS-CoV-2 according to the vaccination schedule recommended by WHO. A vaccine response was considered positive when seroconversion was observed after one dose of vaccine. The clinical efficacy of immunization was defined as the absence of new COVID-19 infection in patients who received a complete vaccination. Results: Among the 81 patients included in the study, 7.4% had anti-Spike IgM antibodies before their first vaccination. Seroprevalence of IgM antibodies was 38.3% one month after the first vaccine dose (at M1) and 8.6% one month after the second dose (at M4). Anti-Spike IgG antibodies were present in 40.3% of patients before vaccination, in 90.1% at M1, and in 59.7% at M4. Among patients previously infected with SARS-CoV-2, 10.2% had IgM antibodies at M0, 31.6% at M1, and 10.5% at M4 post-vaccination. Similarly, seroprevalences of IgG antibodies in this subgroup were 31.5%, 61.3%, and 50.0% respectively at M0, M1, and M4 post-vaccination. A comparison of seroconversion rates between M0 and M4 showed significant differences only for IgG in COVID-19 naive patients. Mean duration in dialysis and the existence of previous COVID-19 infection were associated with patients’ vaccinal response after the two doses. Age, gender and the use of immunosuppressive treatment did not influence post-vaccinal antibody production. Conclusion: Vaccination against COVID-19 in Senegalese hemodialysis patients induced a low seroconversion rate but it was well tolerated. Moreover, the induced protection was neither strong nor durable, particularly in patients with longer duration in dialysis.

Advancing Pediatric Hemodialysis Care through the Novel Intervention in Children’s Healthcare (NICH) Program

Racial, ethnic, and socioeconomic disparities present daunting hurdles that prevent equitable health outcomes for patients with end-stage kidney disease (ESKD) on hemodialysis. Additional resources, such as the Novel Intervention in Children’s Health (NICH) at Lucille Packard Children’s Hospital Stanford, provide individualized support to best assist families by assessing barriers to care with the goal of improving health outcomes. In this retrospective cohort study, we reviewed patients with ESKD on hemodialysis involved in NICH to explore if NICH serves as a liaison between the patients and multidisciplinary medical team and to explore if NICH helps patients better manage the challenges of end-stage kidney disease. Through the electronic medical record system, EPIC, we reviewed the patients’ surveys to identify barriers to care, which included school and life engagement difficulty, lack of mental health resources, food and transportation insecurity, and cultural/language barriers. We also tracked the number of hospitalizations and ED visits before and during the patients’ enrollment in NICH. We discovered that through NICH, the aforementioned barriers to care were eliminated, the number of hospitalizations and emergency department visits was reduced, and all patients transitioned from inactive to active on the transplant list. NICH successfully improved the health outcomes of these patients and empowered patients to be more engaged in their care.

Causes and Prognosis of Cases of Acute Obstructive Renal Failure Managed at the Donka National Hemodialysis Center

Introduction: Acute obstructive renal failure (AORF) is a frequent clinical situation, secondary to obstruction of the urinary excretory tract. Whatever the cause, urinary tract obstruction suddenly opposes glomerular filtration and is responsible for tubulointerstitial lesions. It accounts for 10% of acute renal failure (ARF). The aim of this study was to identify the causes and prognosis of cases of acute obstructive renal failure managed at the Centre National d’hémodialyse Donka. Material and Methods: This was a prospective descriptive study lasting 6 months, from September 1, 2022 to February 29, 2023. All patients undergoing haemodialysis for acute obstructive renal failure who agreed to participate in the study and whose medical records were complete were included. Results: During the course of the study, we registered 97 haemodialysis patients, including 20 cases (20.62%) of acute obstructive renal failure. The mean age of the patients was 57.8 ± 10.54 years, with a male predominance of 11 cases (55%) and a sex ratio of 1.22. The reasons for consultation were dominated by physical asthenia 11 cases (55%), lumbar pain 9 cases (50%), vomiting 6 cases (30%) and acute urine retention 6 cases (30%). Arterial hypertension 16 cases (80%) and urinary tract infection 10 cases (50%) were the most common antecedents. The etiologies of RAOI were dominated by lithiasis 10 cases (50%), neoplasia 6 cases (30%) and benign prostatic hypertrophy 3 cases (15%). mean creatinine was 1267.60 ± 710.76 μmol/l with extremes of 243 μmol/l and 2822 μmol/l, mean urea was 39.56 ± 18.36, hyperkalemia in 14 cases (70%) and hyponatremia in 8 cases (40%). After hemodialysis, 9 cases (45%) recovered renal function, 4 cases (20%) became chronic and 7 cases (35%) died. Conclusion: The frequency of AKI remains non-negligible in our department, and early detection and prompt management would considerably reduce the morbidity and mortality associated with this pathology.

The impact of foot reflexology on fatigue and sleep quality in school-aged children undergoing hemodialysis

Objective:This study aimed to evaluate the effects of foot reflexology on fatigue and sleep quality in school-aged children receiving hemodialysis.Methods:A quasi-experimental pretest-posttest design was utilized.Thirty children of ages 6-12 undergoing in-center hemodialysis were recruited.The Pittsburgh Sleep Quality Index(PSQI)and Inventory of Fatigue Symptom(IFS)scales were administered at baseline.Participants then received 30 min of foot reflexology massage before hemodialysis sessions 3 days per week for 12 weeks.Posttest administration of the sleep and fatigue scales occurred after the intervention period.Results:Reflexology massage led to significant improvements in sleep quality components,including duration(0%-30%normal sleepers),efficiency(0%-50%>85%),latency(50%-0%>60 min),disturbances,and daytime dysfunction.The mean PSQI score decreased from 18.2 to 9.7(P<0.05).Fatigue severity substantially decreased,with the mean IFS score improving from 105.7 to 64.1(P<0.05).Conclusion:Foot reflexology is an effective nursing intervention for reducing fatigue and improving sleep quality in children on hemodialysis,warranting integration into routine care.

Outcomes of Hemodialysis Patients in Public Centres in Abidjan from September 2018 to October 2021: Data from the Renal Registry of Cote d’Ivoire

Background: Hemodialysis is the most widely used renal replacement therapy in developing countries such as Cote d’Ivoire. Objective: To study the outcome of chronic hemodialysis patients in public centres in Abidjan using data from the Renal Registry of Cote d’Ivoire (2RCI). Method: This was a prospective analytical cohort study of End Stage Kidney Disease (ESKD) patients undergoing iterative hemodialysis in the network of public hemodialysis centres in Abidjan and who had been registered in the 2RCI register by September 2018. Results: Our study involved 363 cases out of 379 patients registered in the 2RCI registry database in 2018. The mean age of the patients was 47.3 ± 12.1 years, with a male predominance (sex ratio 1.97). In 70.24% of cases, they had no health insurance. The average duration of dialysis for our patients was 6.94 ± 4.1 years, with extremes of 2 and 28 years. This duration was less than 5 years in 44.3% of cases, between 6 and 10 years in 42.9% and more than 10 years in 12.6% of cases. The comorbidities found were hypertension in 95.6% of cases, diabetes in 7.8% and HIV in 4.6%. Anemia was found in 68% of cases and stroke in 8.6%. During the study period, 161 deaths were observed, representing a mortality rate of 44.35%. Acute lung oedema (29.8%), stroke (6.8%) and other cardiovascular diseases (19.3%) were the main causes of death. In multivariate analysis, factors such as age ≥ 65 years (HR = 3.66;CI 95% = 1.55 - 8.67;p = 0.003), “married/coupled” status (HR = 2.02;CI 95% = 1.24 - 3.31;p = 0.005) and normal weight at the start of dialysis (OR = 9.59, CI95% = 4.19 - 21.95;p = 0.001) were associated with the risk of death. Conclusion: Hemodialysis is performed in Abidjan on young patients. The mortality rate after three years of dialysis is very high. Hence the need to pursue the policy of decentralizing public centres and optimizing access to dialysis in terms of quality and quantity in order to improve patient survival.
