RESUMEN

The quality of life (QoL) and sleep quality are closely linked to the physical and psychological health of end-stage renal disease (ESRD) patients, especially those underwent hemodialysis (HD) therapy. This study aims to investigate the impact of 830 nm laser treatment on improving QoL and sleep quality in HD patients. Forty ESRD patients participated in this study. 830 nm laser was used to radiate on the palm (at dose of 256.10 J/cm2), ST 36 and KI 1 acupoints (at dose of 109.76 J/cm2) of HD patients, and QoL and sleep quality questionnaires were utilized to assess changes following the treatment. After 830 nm laser radiation, lower global Pittsburgh Sleep Quality Index and Athens Insomnia Scale scores were observed, accompanied by higher physical and mental component summary scores in MOS 36-item short-form health survey version 2 and a global World Health Organization Quality of Life Brief Version score. The laser group also showed significant improvements in QoL and sleep quality indicators. Additionally, pain levels decreased on the third day and after one month according to visual analogue scale. This study revealed the positive effects of 830 nm laser on palm, KI 1 and ST 36 acupoints for improving the QoL and sleep quality in ESRD patients underwent HD treatment. The results suggest that 830 nm laser applied to specific targets could be used as a complementary and alternative approach to increase the QoL and sleep quality in ESRD patients.

RESUMEN

When elder individuals develop chronic kidney failure, doctors, patients, and family members are faced with the decision: Should dialysis (still) be initiated, or should a conservative-palliative therapy strategy be chosen? A prerequisite for shared decision-making is structured education about the various options, ensuring all necessary information and consequences are communicated. This article outlines the advantages and disadvantages of haemodialysis and peritoneal dialysis, as well as conservative-palliative therapy. Additionally, it discusses the option of a trial dialysis and the choice to discontinue ongoing dialysis.

RESUMEN

Long-term treatment of anemia involving frequent blood transfusions and intravenous iron administration increases the risks of hepatic iron overload and steatosis in the patients undergoing hemodialysis.Pathological accumulation of iron damages hepatocytes,not only elevating the risks of progressive hepatic fibrosis and cirrhosis but also potentially accelerating the process of hepatic steatosis.Iron overload and steatosis may interact with each other,exacerbating liver damage and ultimately leading to further deterioration of hepatic fibrosis and cirrhosis.MRI characterized by non-invasiveness and high repeatability,enables the simultaneous quantitative assessment of hepatic iron and fat content,providing crucial information for early diagnosis and intervention of liver diseases.In recent years,researchers have achieved significant advances in the application of MRI in the diagnosis and treatment of liver diseases.MRI can accurately reflect the extent of hepatic iron overload and steatosis in patients and predict the risk of liver diseases.This article reviews the latest advances,challenges,and perspectives in the application of MRI in assessing hepatic iron overload and steatosis in the patients undergoing hemodialysis,aiming to offer valuable references for clinical practice.

RESUMEN

In times in which climate change is becoming increasingly noticeable in the everyday lives of the global population, a rethinking towards an environmentally friendly and climate-neutral way of life is essential in all areas of human activity (including medicine). In the field of nephrology, a reorientation of resource-intensive renal replacement therapy is therefore absolutely necessary, keyword "green nephrology". To this end, awareness of the CO2 emissions caused in the field of nephrology must first be raised so that CO2 savings can then be implemented efficiently. Initially using the current conventional dialysis procedures. In addition, further technical developments such as portable and wearable haemodialysis and peritoneal dialysis machines will enable significant savings in energy and water consumption in the future. Furthermore, innovative research approaches are introducing new alternatives to organ transplantation, such as xenotransplantation, stem cell research and "artificial" organ replacement.A wide variety of promising approaches is therefore available for the renal replacement therapy of the future. The aim of nephrology must now be to drive forward further development and implement it in such a way that environmentally friendly patient care in nephrology is possible in the near future in order to make our contribution to climate protection while at the same time ensuring the treatment and its quality.

RESUMEN

This study is aimed to investigate the effect of hemodialysis (HD) on the lamina cribrosa (LC) of the optic nerve head (ONH) using swept-source optical coherence tomography (SS-OCT) and other ophthalmological parameters in patients with end-stage kidney disease (ESKD). This prospective observational study included 29 patients who underwent HD for ESKD. ONH parameters including neural canal diameter (NCD), peripapillary vertical height (PVH), and anterior LC depth (LCD), were assessed using SS-OCT. Changes in the ONH parameters before and after HD were statistically analysed. Correlations between changes in the LCD and other ocular and systemic measurements were identified using Pearson's correlation analyses. The mean anterior LCD significantly decreased from 441.6 ± 139.8 µm before HD to 413.5 ± 141.7 µm after HD (P = 0.001). Mean NCD and PVH did not show significant changes after HD (P = 0.841 and P = 0.574, respectively). A significant correlation was found between changes in the anterior LCD and the mean ocular perfusion pressure (r = 0.397, P = 0.036). We observed a significant decrease in anterior LCD after HD. Our study suggests that HD can influence the ONH, especially in the LC.

RESUMEN

The objective of this cross-sectional study was to examine the extent of sleep quality among individuals undergoing maintenance hemodialysis (MHD) and to scrutinize whether hope and family function serve as mediators in the association between anxiety and sleep quality in this cohort. A convenience sampling method was used to recruit 227 patients receiving maintenance hemodialysis from two tertiary hospitals in Wuhan. Participants completed several self-report questionnaires, including the Sociodemographic questionnaire, Hospital Anxiety and Depression Scale, Athens Insomnia Scale, Herth Hope Index, and Family APGAR Index. As per the findings of the chain mediation analysis, it was observed that the sleep quality scores were directly predicted by anxiety. Moreover, anxiety positively predicted sleep quality scores through hope and family function as mediators. The observed types of mediation were partial mediation. The total indirect effect value was 0.354, indicating the mediating effect of hope and family function, while the total effect value was 0.481, representing the overall effect of anxiety on sleep quality. The total effect size was 73.60% (0.354/0.481), indicating that the mediation accounted for a significant portion of the relationship. This study established the chain mediating effect of hope and family function between anxiety and sleep quality in patients receiving maintenance hemodialysis. The findings highlight the importance of addressing anxiety and promoting hope and family function to improve sleep quality in this population. The findings suggest that healthcare professionals should be attentive to the anxiety levels of these patients and implement targeted interventions to help alleviate anxiety, enhance hope, and improve family functioning, with the ultimate goal of improving sleep quality in this population.

RESUMEN

BACKGROUND: The emergence of new SARS-CoV-2 variants and the global COVID-19 pandemic spurred urgent vaccine development. While common vaccine side effects are well-documented, rare adverse events necessitate post-marketing surveillance. Recent research linked messenger RNA vaccines to thrombotic microangiopathy (TMA), a group of syndromes characterized by microvascular hemolytic anemia and thrombocytopenia. This report describes a new-onset atypical hemolytic-uremic syndrome (aHUS) occurring after COVID-19 vaccination and complements recent literature. CASE PRESENTATION: A previously healthy 25-year-old woman developed malaise, nausea, edema, and renal dysfunction 60 days postvaccination. Laboratory findings confirmed TMA diagnosis. Genetic testing for complement system mutations was negative. Kidney biopsy supported the diagnosis, and the patient required hemodialysis. CONCLUSION: This case illustrates the rare occurrence of aHUS following COVID-19 vaccination, with unique characteristics compared to previous reports. Despite the critical role of vaccination in pandemic control, emerging adverse events, such as vaccine-related TMA, must be recognized and investigated. Additional clinical trials are imperative to comprehend the clinical features and pathophysiological mechanisms underlying TMA associated with COVID-19 vaccination.

RESUMEN

This study aimed to identify differences in the composition of whole blood of patients with chronic kidney disease (CKD), before and after a hemodialysis session (HDS), and possible differences in blood composition between stages and between genders using Raman spectroscopy and principal component analysis (PCA). Whole blood samples were collected from 40 patients (20 women and 20 men), before and after a HDS. Raman spectra were obtained and the spectra were evaluated by PCA and partial least squares (PLS) regression. Mean spectra and difference spectrum between the groups were calculated: stages Before and After HDS, and gender Women and Men, which had their most intense peaks identified. Stage: mean spectra and difference spectrum indicated positive peaks that could be assigned to red blood cells, hemoglobin and deoxi-hemoglobin in the group Before HDS. There was no statistically significant difference by PCA. Gender: mean spectra and difference spectrum Before HDS indicated positive peaks that could be assigned to red blood cells, hemoglobin and deoxi-hemoglobin with greater intensity in the group Women, and negative peaks to white blood cells and serum, with greater intensity in the group Men. There was statistically significant difference by PCA, which also identified the peaks assigned to white blood cells, serum and porphyrin for Women and red blood cells and amino acids (tryptophan) for Men. PLS model was able to classify the spectra of the gender with 83.7% accuracy considering the classification per patient. The Raman technique highlighted gender differences in pacients with CKD.

RESUMEN

Purpose: The serum lipid level is strongly associated with atherosclerosis. However, research on the relationship between lipid-derived indices and acute ischemic stroke (AIS) occurrence in hemodialysis populations is limited. This study aimed to explore the predictive value of lipid-derived indices, including atherogenic index of plasma (AIP), Non- high density lipoprotein cholesterol (Non-HDL-C), Non-HDL-C/HDL-C, and lipoprotein combine index (LCI) in clinical practice for the occurrence and prognosis of AIS in hemodialysis patients. Methods: A total of 451 patients undergoing maintenance hemodialysis were screened and 350 were enrolled in this study. The lipid parameters exhibit a progressive increase across the tertiles, with values rising from Q1 through Q3. Enrolled patients were divided into three groups (Q1, Q2, and Q3) based on tertiles of AIP, Non-HDL-C, Non-HDL-C/HDL-C, and LCI values. Kaplan-Meier curves were performed to investigate the association between the AIP, Non-HDL-C, Non-HDL-C/HDL-C, LCI and AIS-free survival in hemodialysis patients. Chi-square analysis was used to explore the association between the AIP, Non-HDL-C, Non-HDL-C/HDL-C, LCI and AIS outcomes in hemodialysis patients. AIS outcomes were assessed using the modified Rankin Scale (mRS). Results: Kaplan-Meier analysis revealed that the AIS-free survival rates were significantly higher in the Q1 group compared to Q2 and Q3 groups for AIP, Non-HDL-C, Non-HDL-C/HDL-C, and LCI. Log rank tests showed statistically significant differences between the Q1 group and the Q2 and Q3 groups (p < 0.05 for all). The proportion of patients with a good outcome mRS was higher in the Q1 group compared to the Q2-Q3 groups (AIP: 0.818 vs 0.792; Non- HDL-C: 0.866 vs 0.767; Non- HDL-C/HDL-C: 0.867 vs 0.767; LCI: 0.938 vs 0.750). Conclusion: The four lipid-derived parameters are effective predictors of AIS in patients undergoing hemodialysis, and AIP has a strongest correlation with the risk of AIS. Hemodialysis patients with elevated levels of the four lipid-derived indices had a higher incidence of AIS and poorer functional outcomes compared to those with lower levels. Our conclusions may require confirmation by further research in the future.

RESUMEN

Patients receiving hemodialysis (HD) often develop gastrointestinal diseases. Recently, although in general population, clinical guidelines for Helicobacter pylori have strongly recommended its eradication in patients to prevent gastric cancer, optimal eradication regimen and optimal dosage of drugs for patients receiving HD have not been established, due to possible incidence of adverse events. Some antimicrobial agents used in eradication therapy, particularly amoxicillin, can exacerbate renal dysfunction. Given the delayed pharmacokinetics of drugs in patients receiving HD compared with those in healthy individuals, drug regimen and dosage should be considered to minimize adverse effects. Although previous studies have investigated the benefits of eradication therapy for patients receiving HD, because most studies were small in terms of the number of enrolled patients, it is hard to show evidence. The numbers of eradication in HD patients have recently increased, and it is important to provide an optimal regimen. The consideration of eradication in patients undergoing HD with a reduction in the drug dose by 1/2-1/3 may prevent adverse events. Additionally, another important consideration is whether adverse events can be prevented while maintaining a similar eradication rate with reduced drug dosages. Recent meta-analysis findings indicate comparable eradication rates in patients receiving HD and healthy individuals, both with the same dosage regimen and at a reduced dosage regimen, with no significant differences (relative risk [RR] for successful eradication: 0.85 [95% confidence interval (CI): 0.48-1.50]). Unlike with the same dosage regimen (RR for adverse events: 3.15 [95% CI: 1.93-5.13]), the adverse events in the dosage reduction regimen were similar to those in healthy individuals (RR: 1.26 [95% CI: 0.23-6.99]). From a pharmacological perspective, the eradication regimen in patients receiving HD should consider the dosage (1/2-1/3 dosage), dosing number (bid), dosing timing of drugs (after HD), and susceptibility to antimicrobial agents.

RESUMEN

BACKGROUND Heart failure and end-stage renal disease often coexist, and management of heart failure can be challenging in patients during hemodialysis. Sacubitril-valsartan (SV) is the first drug to receive regulatory approval for use in patients with chronic heart failure with reduced ejection fraction (HFrEF) and New York Heart Association (NYHA) classification II, III, or IV. This study aimed to evaluate the efficacy and safety of SV for use in chronic heart failure patients on maintenance hemodialysis (MHD). MATERIAL AND METHODS From September 2021 to October 2022, 28 patients on MHD with chronic heart failure at the hemodialysis center of Shaanxi Second Provincial People's Hospital were regularly followed. During the 12-week follow-up period, all patients were administered SV at doses of 100-400 mg per day. Biochemical indicators, echocardiographic parameters, life quality scores, and adverse events were evaluated. RESULTS We enrolled 28 patients. Compared with the baseline levels, NYHA class III in these patients treated with SV was significantly decreased from 60.71% to 32.14% (P<0.05), left ventricular ejection fraction (LVEF) was significantly improved from 44.29±8.92% to 53.32±7.88% (P<0.001), the Physical Component Summary (PCS) score was significantly improved from 40.0±6.41 to 56.20±9.86 (P<0.001), and the Mental Component Summary (MCS) score was significantly improved from 39.99±6.14 to 52.59±11.0 (P<0.001). CONCLUSIONS We demonstrated that SV improved NYHA classification and LVEF values of patients on MHD with chronic heart failure and also improved their quality of life.

RESUMEN

INTRODUCTION AND OBJECTIVES: Functional and durable vascular access is needed for adequate hemodialysis. Arteriovenous fistula is preferred over prosthetic grafts or central venous catheters, but it is associated with high rates of primary failure and maturation failure. Preoperative mapping of arm vessels with color Doppler ultrasound (CDU) has been shown to be helpful in achieving better short and long-term outcomes. Unfortunately, is more time-consuming than a physical examination and requires an experienced examiner and special equipment; some authors defend that CDU should not be part of the routine preoperative assessment. We reported our experience in preoperative vessel mapping using color Doppler ultrasound to purpose a vascular access to the surgical team, surveillance of vascular access, and evaluation of main outcomes (primary failure, maturation failure, and patency). METHODS: This is a single-center retrospective study that includes patients who attended a specific appointment for vascular access planning consultation between January 2019 and December 2021. A nephrologist performed the physical exam and vascular mapping and proposed to the vascular surgeon team a specific type and location of vascular access. Patients were followed until one month after the first hemodialysis through functioning vascular access. RESULTS: In this study, 167 patients were evaluated (114 incident patients - chronic kidney disease stage 4 or 5 - and 53 prevalent patients - under hemodialysis through central venous catheter). The vascular accesses proposed by nephrologist were radial-cephalic arteriovenous fistula in 70 patients (41.9%), brachio-cephalic arteriovenous fistula in 50 patients (29.9%), brachio-basilic arteriovenous fistula in 34 patients (20.4%), arteriovenous graft in 8 patients (4.8%) and central venous catheter in 2 patients (1.2%). Vascular access was constructed in 141 patients: distal arteriovenous fistula in 57 patients (40.4%), brachio-cephalic arteriovenous fistula in 54 patients (38.3%), brachio-basilic AVF in 27 patients (19.1%), and arteriovenous graft in 3 patients (2.1%). The created access corresponds to the proposed access in 129 patients (91.5%). Twenty-two (15.6%) primary failures were registered. Distal arteriovenous fistulas and diabetes mellitus were associated with a higher risk of primary failure (OR=3.929 (1.485-10.392), p=0.004; OR=3.867 (1.235-12.113), p=0.014, respectively). The incidence of maturation failure at eight weeks was 4.8%. The primary patency at 6, 12 and 24 months was 76.3%, 70.4% and 49.2%. Primary assisted patency was 84.8% at 6 and 12 months and 81.3% at 24 months. CONCLUSIONS: This study demonstrates that the study of the entire vascular territory performed with color Doppler ultrasound, within a multidisciplinary team of nephrologists and vascular surgeons, is associated with high rates of autologous access and very low rates of primary failure and maturation failure (almost unprecedented in the literature).

RESUMEN

End-stage renal disease (ESRD) patients are considered immunocompromised, putting them at high risk for infections, including cytomegalovirus (CMV). CMV can affect hematological parameters, causing further complications in ESRD patients. This study intended to determine the seropositivity of CMV infection in hemodialysis patients and its effect on different blood parameters in ESRD patients to help decrease the overall dialysis associated morbidity and mortality. Blood samples were collected from 45 ESRD patients and 45 controls. A complete blood count was performed using an automated cell counter. CMV-specific IgM and IgG levels were measured using immunochemistry testing. The seropositivity for CMV-IgG was 42.2% in ESRD patients which was significantly higher than in control group (22.2%) (p=0.042). The seropositivity for CMV-IgM was 6.7% in ESRD patients with no difference with the control group (4.4%). The prevalence of anemia was significantly higher in CMV seropositive (77.3%) compared to CMV seronegative (47.8%) ESRD patients. Other studied blood parameters were not different between CMV seronegative and seropositive ESRD patients. In conclusion, CMV infection is a significant concern for dialysis patients and can affect hematological parameters, leading to further complications. Early detection and treatment of CMV infection and monitoring of CMV IgM and IgG levels are critical to prevent further complications and improve clinical outcomes.
