Effect of mental state on sleep quality in patients receiving maintenance hemodialysis: A multiple mediation model of hope and family function.

The objective of this study was to investigate the current situation of sleep quality in patients receiving maintenance hemodialysis (MHD), and whether hope and family function play a mediating role between negative emotions and sleep quality. The Athens Insomnia Scale, Hospital Anxiety and Depression Scale, Herth Hope Index and Family Adaptation, Partnership, Growth, Affection and Resolve (APGAR) Index were used to investigate 227 MHD patients. The correlations among study variables were analyzed by Pearson correlation analysis. Structural equation model was used to construct and evaluate the mediation model. The sleep quality score of 227 patients receiving MHD was (7.57 ± 4.74), anxiety score was (4.36 ± 4.02), depression score was (5.91 ± 4.37), hope score was (34.64 ± 7.21), family function score was (6.21 ± 2.90). The negative emotions can directly predict sleep quality (β = 0.17, P = .046), positively predict sleep quality through hope (β = 0.12, P = .017), positively predict sleep quality through family function (β = 0.20, P < .001), and positively predict sleep quality through the chain mediating of hope and family function (β = 0.10, P < .001). The total effect size was 71.19%. It is concluded that negative emotions had a direct impact on the sleep quality of patients receiving MHD, and that improving the levels of family function and hope can help them sleep better.

Hepatitis C virus infection increases risk of peripheral arterial disease in end‐stage renal disease patients receiving maintenance hemodialysis therapy

AbstractBoth hepatitis C virus (HCV) infection and end‐stage renal disease are associated with an increased risk of developing peripheral arterial disease (PAD). Our objective was to explore the relationship between HCV infection and PAD in hemodialysis patients, using brachial‐ankle pulse wave velocity (baPWV) as the assessment method. Since 2016, we have actively been recruiting patients undergoing regular hemodialysis three times a week. All baPWV assessments for our patients were performed before the implementation of direct‐acting antiviral treatment. Furthermore, none of the uremic patients with HCV infection had received interferon‐based treatment in the past. An elevated baPWV measurement surpassing 2100 cm/s is indicative of an increased susceptibility to potential PAD. Our analysis utilized multivariate linear and logistic regression analysis. Individuals with HCV infection exhibited higher baPWV levels compared with those without HCV infection (2006.0 ± 687.4 vs. 1809.3 ± 466.1 cm/s, p = .039). The presence of HCV infection (β = 199.56, 95% CI: 10.56–388.56, p = .039) demonstrated a significantly positive correlation with baPWV levels. In the multivariate logistic regression analysis, HCV infection (OR = 2.67, 95% CI: 1.07–6.68, p = .036) significantly associated with baPWV &gt;2100 cm/s. Furthermore, individuals with a higher viral load (HCV RNA ≥60 × 103 IU/mL) (OR = 4.45, 95% CI: 1.12–17.68, p = .034) demonstrated a significant association with baPWV ≥2100 cm/s when compared with non‐HCV infection patients. Additionally, patients with genotype I exhibited a significant association with baPWV ≥2100 cm/s (OR = 8.13, 95% CI: 2.04–32.42, p = .003) in comparison to non‐HCV patients. The presence of HCV infection has been demonstrated to markedly increase baPWV levels. Particularly, HCV infection with higher viral load and genotype I is significantly linked to an elevated risk of PAD. It emphasizes the importance of HCV elimination in the specific population.

Breast and Prostate Cancer Screening by Life Expectancy in Patients with Kidney Failure on Dialysis.

The Choosing Wisely campaign suggests an individualized approach to cancer screening among patients receiving dialysis. We aimed to evaluate breast and prostate cancer screening among patients receiving maintenance hemodialysis (HD) by kidney transplant waitlist status and five-year survival probability. We conducted a retrospective cohort study using a nationally representative population of HD patients. Patients receiving HD each calendar year from 2003-2018, ≥1 year of Medicare as the Primary Payer, and age 50-69 years were included. The cohort was split into prognosis and cancer screening sets. Models of five-year survival were built in the prognosis set using logistic regression. Five-year survival probabilities were generated in the cancer screening set, excluding patients with prior breast or prostate cancer, and screening over the next year was assessed. 160,537 patients contributed 356,165 person-years to the cancer screening set (59% of the person-years were contributed by males, median age was 60 years). Compared to a benchmark rate of 50% (e.g., mammography every other year), 42% of waitlisted female-years were screened by mammography. Overall, 17% of non-waitlisted female-years were screened (20% among those with >50% probability of five-year survival and 8% among those with <10% probability of five-year survival). Compared to a benchmark rate of 20% [e.g., serum prostate-specific antigen (PSA) screening up to five years apart], 24% of waitlisted male-years were screened with serum PSA. Overall 15% of non-waitlisted male-years were screened (13% among those with >50% probability of five-year survival and 1% among those with <10% probability of five-year survival). Patterns were similar after age-standardization. Patients with higher predicted survival have higher rates of cancer screening, suggesting providers consider life expectancy. However, non-waitlisted patients with high probability of five-year survival were less likely to be screened compared to waitlisted patients. Interventions may be needed to close this screening gap.

Construction of frailty and risk prediction models in maintenance hemodialysis patients: a cross-sectional study.

As the prevalence of diabetic nephropathy and hypertensive nephropathy increases with age in mainland China, the number of patients with end-stage renal disease is increasing, leading to an increase in the number of patients receiving maintenance hemodialysis. Considering the harmful effects of frailty on the health of maintenance hemodialysis patients, this study aims to identify hemodialysis patients at risk for frailty at an early stage, in order to prevent or delay the progression of frailty in the early stage, so as to prevent the adverse consequences of frailty. A total of 479 patients admitted to the blood purification centers of two grade tertiary hospitals in Anhui Province, China, using convenient sampling. The Frailty Scale, the SARC-F questionnaire, the Simplified Food Appetite Questionnaire (SNAQ) and the mini nutritional assessment short-form (MNA-SF) were used in the study. Pearson correlation analysis was used to explore the correlation among the frailty influencing factors. The incidence of frailty was 24.0% among 479 Chinese hemodialysis patients. Gender (p < 0.05), Malnutrition (p < 0.001), sarcopenia (p < 0.001), and feel tired after dialysis (p < 0.001) were highly correlated with frailty in Chinese hemodialysis patients. Serum albumin concentration (p < 0.05) was a protective factor of frailty. This survey shows that frailty was highly prevalent among Chinese hemodialysis patients. Medical staff and their families should make early judgments and carry out interventions on the risk of frailty.

Utility of ultrasound in measuring quadriceps muscle thickness in patients receiving maintenance hemodialysis: comprehensive systematic review and meta-analysis.

Muscle wasting, a prevalent issue in hemodialysis patients, is effectively assessed by measuring quadriceps muscle thickness, a crucial health indicator. This meta-analysis integrates findings from various studies on the application of ultrasonography (US) for measuring the thickness of quadriceps muscles in patients undergoing maintenance hemodialysis. We conducted a thorough literature search across PubMed, Scopus, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science up to April 2023. The R software's Meta package was used for mean difference analysis of quadriceps rectus femoris thickness (QRFT) and quadriceps vastus intermedius thickness (QVIT) between hemodialysis patients and healthy controls. All of the patients entered the meta-analysis are Caucasians. Sub-group analyses based on measurement sites and pre- and post-dialysis comparisons were performed. Among 15 studies with 1584 patients, a significant decrease in QRFT and QVIT was observed in hemodialysis patients compared to healthy controls (mean difference = 0.40cm, 95% CI: -0.49 to -0.31 and 0.46cm, respectively). Right and left QRFT were notably thinner in hemodialysis patients (RT: mean difference = 0.39cm; LT: mean difference = 0.42cm). Similarly, right and left QVIT were notably thinner in hemodialysis patients (RT: mean difference = 0.45cm; LT: mean difference = 0.47cm). No significant pre- and post-dialysis QRFT differences were found. Ultrasonography is a reliable, accessible tool for assessing quadriceps muscle thickness in hemodialysis patients, revealing consistent muscle thickness reduction. These findings emphasize the need for routine muscle health monitoring in this population and support ultrasound use for regular assessments.

Mediterranean-DASH Diet Intervention for Neurodegenerative Delay Diet and Psychological Problems in Maintenance Hemodialysis Patients by the Structural Equation Modeling Analysis of Malnutrition and Inflammation Markers Approach

ObjectiveAlthough it is known that diet quality affects psychological problems in hemodialysis patients, there is need to explain the role of modifiable risk factors in this relationship. Therefore, the aim of this study was a) to investigate the relationship between diet quality and modifiable risk factors to depression and anxiety in end-stage renal disease (ESRD) patients receiving maintenance hemodialysis; b) to explore the mediating roles of modifiable factors in the relationship with diet quality to depression and anxiety. MethodsThis cross-sectional study included 216 patients with ESRD receiving maintenance hemodialysis treatment. We assessed participants' dietary records for Mediterranean-DASH Diet Intervention for Neurodegenerative Delay (MIND) quality, Global Leadership Initiative on Malnutrition (GLIM) criteria for malnutrition and Hospital Anxiety and Depression (HAD)-scale for psychological problems. Furthermore, biochemical findings and anthropometric measurements were performed to evaluate nutritional markers, metabolic risk factors and inflammation. We applied hierarchical regression analysis to estimate modifiable risk factors for depression and anxiety and Structural-Equation-Modeling analysis to determine the mediating role of modifiable risk factors between diet quality and psychological problems. ResultsDepression symptoms were observed in 59.2% (n=128) of the participants, whilst the rate was 35.1% (n=76) for anxiety. Depression and anxiety were found to be negatively correlated with MIND levels after covariate adjusting model, and the rates of explanation were found to be 16.2% and 12.2%, respectively. C-reactive protein (CRP), albumin levels and the presence of malnutrition were shown to be significant predictors of depression (ΔF=14.761 and ΔR2:0.071 for covariate-adjusted model). Albumin levels, CRP, hemodialysis duration, and malnutrition were found to be independent predictors of anxiety (ΔF=16.174 and ΔR2:0.077 for covariate-adjusted model). It was found that CRP and malnutrition partially mediated the association of MIND score with depression, and CRP mediated the association with anxiety. ConclusionIt was concluded that adherence to the MIND diet is associated with a better nutritional profile and reduced inflammation, which in turn may be linked to fewer psychological problems.These further studies are needed to validate and expand upon our findings.

Medication Burden and Adverse Cardiovascular Events and Death in Patients Treated with Maintenance Hemodialysis

Key Points A higher medication burden was associated with a higher risk of adverse events in patients receiving maintenance hemodialysis.Medication burden can serve as a clinically relevant risk indicator for cardiovascular events and all-cause death in patients on maintenance hemodialysis. Background A high medication burden is associated with adverse outcomes. Although patients with ESKD have a substantial medication burden, the relationship between the number of medications in use and clinical outcomes in these patients remains unclear. Hence, this study aimed to investigate the prognostic implications of medication burden regarding adverse outcomes in patients with ESKD on maintenance hemodialysis. Methods We analyzed 29,690 patients receiving maintenance hemodialysis who participated in the Periodic Hemodialysis Quality Assessment conducted by the Health Insurance Review and Assessment Service. The exposure of interest was the number of routinely prescribed oral medications. The main outcome was a composite of nonfatal cardiovascular events (nonfatal myocardial infarction, coronary revascularization, nonfatal stroke, or hospitalization for heart failure) or all-cause death (major adverse cardiac and cerebrovascular events [MACCEs]). The secondary outcomes were the individual components of the primary outcome. Results During a follow-up period of 146,749 person-years (median, 6.0 years), MACCEs occurred in 17,573 patients (59.2%). Higher medication burden was associated with progressively higher incidence of MACCEs (84.7, 107.2, 130.2, and 168.9 events per 1000 person-years in Q1–Q4, respectively). In a multivariable Cox proportional hazard model, the adjusted hazard ratios (95% confidence intervals) for the second, third, and highest quartiles were 1.05 (1.00 to 1.10), 1.12 (1.07 to 1.17), and 1.27 (1.21 to 1.33), respectively, compared with the lowest quartile. In continuous modeling, each increase in the number of medication was associated with a 1.03-fold (95% confidence interval, 1.03 to 1.04) higher risk of the primary outcome. Conclusion A high medication burden was independently associated with higher risk of adverse cardiovascular outcomes and all-cause death in patients receiving maintenance hemodialysis. These findings suggest that a high medication burden could be a useful indicator of adverse clinical outcomes in patients undergoing hemodialysis.

Acceptance of SARS-CoV-2 Surveillance Testing Among Patients Receiving Dialysis

Integrating routine SARS-CoV-2 testing in dialysis facilities may benefit patients receiving dialysis by mitigating risks of serious illness and reducing transmission. Patient acceptance of nonmandatory testing is unknown. To evaluate the acceptance of 2 SARS-CoV-2 testing strategies among patients in hemodialysis facilities nationwide. This nationwide cluster (dialysis facility-level) randomized trial investigated the acceptance of SARS-CoV-2 testing among patients receiving maintenance hemodialysis at facilities located in 22 states. Anterior nares real-time reverse transcriptase-polymerase chain reaction tests offered once every 2 weeks (static testing facilities) vs offered once a week, once every 2 weeks, or once a month depending on county COVID-19 infection prevalence (dynamic testing facilities). Facilities were randomized by county, and tests were offered for 3 months between February 4 and July 24, 2023. The primary outcome was test acceptance. Secondary outcomes included the proportion of patients who accepted at least 1 test. In total, 62 hemodialysis facilities were randomized and 57 participated. Among 2389 participating patients, the median age was 64 (IQR, 54-74) years, 1341 (56%) were male, 138 (6%) were categorized as American Indian, 60 (3%) Asian, 885 (37%) Black, 75 (3%) Native Hawaiian or Pacific Islander, 338 (14%) Hispanic, and 876 (37%) White; and 1603 (67%) had diabetes. A median of 6 (IQR, 6-6) tests were offered per patient in the static arm and 4 (3-6) tests in the dynamic arm. Test acceptance was low: 8% of offered tests were accepted in each of the test arms. Among 503 patients who accepted at least 1 test, the median percentage of offered tests that were accepted was 16% (IQR, 17%-42%) using the static testing strategy and 50% (IQR, 33%-75%) using the dynamic testing strategy (P < .001). Older patients (odds ratio [OR], 1.08 [95% CI, 1.01-1.16] per 5-year age increment), patients with (vs without) diabetes (OR, 1.59 [95% CI, 1.18-2.16]), and women compared with men (OR, 1.30 [95% CI, 0.98-1.73]) were more likely to accept multiple tests. Patients designated in the electronic health record as Hispanic were more likely than patients designated as White (OR, 1.78 [95% CI, 1.15-2.76]) to accept at least 1 test, whereas patients living in zip codes electing Republican representatives to Congress were less likely than patients living in zip codes electing Democratic representatives (OR, 0.34 [95% CI, 0.17-0.69]) to accept multiple tests. In this cluster randomized trial evaluating 2 SARS-CoV-2 testing strategies in dialysis facilities, test acceptance was low, and a dynamic testing strategy anchored to COVID-19 infection prevalence did not outperform a static testing strategy of every 2 weeks.

Symptom Burden in Patients on Maintenance Hemodialysis: Prevalence and Severity 17 Years Apart.

Objectives: The aim of this study is to compare data from two cohorts separated by a 17-year interval. We assessed the prevalence and severity of symptoms with the "dialysis symptom index" in these two groups, recruited in 2007 and 2024, to determine how advancements in dialysis therapy have influenced the symptom burden's prevalence and severity. Methods: End-stage renal diseases patients receiving maintenance hemodialysis three times a week in the hemodialysis unit of the university hospital were recruited between February and March 2007. In May 2024, in the same unit, another population sample was recruited and studied, as in 2007. The Dialysis Symptom Index (DSI) was administered to each patient, during the dialysis treatment. The DSI is made up of 30 questions, each of which addresses a specific physical or emotional symptom. The total symptom burden score, representing the total number of symptoms reported as being present, and the total symptom severity score, which represents the sum of individual severity scores, were generated for each patient. Results: We studied 71 patients in 2007 and 61 patients in 2024. The demographic, clinical and laboratory characteristics of the two study populations did not differ significantly. The total symptom burden score did not differ significantly between 2007 and 2024. The prevalence of most symptoms was similar in the two groups. The prevalence of constipation, decreased interest in sex and difficulty in becoming sexually aroused was higher in 2024 than in 2007. The total symptom severity was similar in the two periods. The severity of most symptoms was similar in the two groups. The severity of decreased interest in sex and difficulty in becoming sexually aroused was higher in 2024 than in 2007. Conclusions: The present study shows that, 17 years apart, the prevalence and severity of the symptom burden in patients on maintenance hemodialysis did not change significantly. These results suggest that studies investigating the causes and the pathogenesis of symptoms of patients on maintenance hemodialysis are urgently needed in the next future, as well as studies on therapeutic strategies.

HEPATITIS C VIRUS AND LEUKEMIA PATIENTS: PREVALENCE AND RISK FACTORS ASSOCIATED WITH INFECTION AMONG LEUKEMIA PATIENTS WHO ACHIEVE LONG-TERM REMISSION AFTER CHEMOTHERAPY

Aim and objective: Leukemia patients are at elevated risk of hepatitis C virus infections, with anti-HCV prevalence ranging from 4.3% to 70% post-chemotherapy remission. Long-term leukemia survivors' natural histories are unclear. We measured anti-HCV antibodies to investigate the frequency of HCV infections and the associated odds factors of contracting HCV among leukemia patients who achieved long-term remissions after chemotherapy. Methods: This study is a cross-sectional study, comprising leukemia patients at the oncology center at Kuwait Hospital in Sana'a, Yemen. It included people with leukemia of different ages and genders. Data was collected through a standard questionnaire prepared for this study, which includes clinical symptoms, risk factors, demographic data, and the results of diagnostic tests. Antibody tests for the hepatitis C virus (HCV) were done by ELISA. Results: The majority of patients with HCV are male, with a mean age of 12.8 years. The prevalence is 5.5%, with males having a higher prevalence. Most patients receive blood transfusions more than twice, with major blood banks, Al-Kuwait hospitals, and private hospitals being the primary sources. AML and ALL are the two most common leukemias. Male patients have a higher risk, and those over 15 years old have a higher risk. Conclusions: This study is the first in Yemen to investigate the prevalence of HCV infections in patients with leukemia. According to our research, leukemia patients had a greater prevalence of HCV than the general population's national prevalence. However, health care workers (HCWs) and patients receiving maintenance hemodialysis (HD) patients have prevalence's of HCV that are comparable.

Burden of Pulmonary Hypertension in End-Stage Renal Disease Patients Receiving Maintenance Hemodialysis: Evaluation Factors and Treatment Strategies.

Background Chronic kidney disease (CKD) is an emerging public health problem in India. Pulmonary hypertension (PH) is an overlooked cardiovascular complication of CKD. This study aimed to estimate the burden of PH among CKD patients undergoing hemodialysis in a selected tertiary care hospital. In addition, it aimed to determine the various factors associated with PH and response to various treatment modalities. Methodology This hospital-based, analytical, cross-sectional study was conducted in the nephrology department of a medical college hospital in Tamil Nadu from March 2023 to March 2024. The study included 150 adults diagnosed with stage 5 CKD and registered for hemodialysis. Results Of the 150 participants, 96 (64%) had PH. Of these, 81 (84%) were males and 15 (16%) were females. In the PH group, 58 (60.4%) had type 2 diabetes mellitus, 52 (54%) had been on dialysis for 6-12 months, 67 (69.8%) had chronic glomerulonephritis, 25 (26.04%) had chronic tubular interstitial nephritis, and 72 (75%) had microcytic anemia. PH patients had significantly higher rates of protein-energy malnutrition (26 (48.2%) vs. 67 (80.7%), p < 0.009) and more frequent hospitalizations (19 (35%) vs. 69 (71.9%)) compared to those without PH. Additionally, PH patients exhibited higher incidences of left ventricular hypertrophy (72% vs. 92%), pericardial effusion (0% vs. 65%), and tricuspid regurgitation (16% vs. 100%). Patients treated with a combination of isosorbide dinitrate (ISDN) and hydralazine; extended hemodialysis; and ISDN, hydralazine, and sildenafil showed significant improvement compared to other treatment modalities. Conclusions The high prevalence of PH among CKD patients undergoing hemodialysis underscores the importance of vigilant monitoring and targeted interventions.

A cross-sectional study on the impact of hemodialysis duration on retinal nerve fiber layer thinning in hemodialysis patients

This study aimed to investigate the relationship between hemodialysis duration (HDD) and retinal nerve fiber layer (RNFL) thickness. A total of 60 patients receiving maintenance hemodialysis and 67 healthy controls were analyzed. Spectral domain optical coherence tomography (SD-OCT) was employed to measure annular RNFL thicknesses. The hemodialysis group exhibited reduced temporal and inferior RNFL thicknesses relative to the control group. In hemodialysis patients, the inferior RNFL thickness was negatively correlated with HDD and positively correlated with intraocular pressure (IOP). Moreover, IOP was positively correlated with HDD. Mediation analysis showed that the negative correlation between HDD and inferior RNFL thickness was mediated by IOP. In conclusion, hemodialysis leads to temporal and inferior RNFL thinning, and the thickness reduction is proportional to hemodialysis duration. However, such changes are not induced by an increase in IOP.

Long-term humoral and cellular responses elicited by Gam-COVID-Vac vaccine in hemodialysis patients: A prospective cohort study

&lt;b&gt;Purpose: &lt;/b&gt;The aim of this study is to assess long-term immunogenicity of the recombinant adenoviruses 26 and 5 vector-based COVID-19 vaccine Gam-COVID-Vac (Sputnik V, developed by N. F. Gamaleya National Research Centre, Russia) in patients receiving maintenance hemodialysis (HD) compared to healthy subjects.&lt;br /&gt; &lt;b&gt;Materials &amp;amp; methods: &lt;/b&gt;A prospective cohort study included patients treated with maintenance HD (n=23) and healthy volunteers (n=28). The levels of anti-severe acute respiratory syndrome coronavirus-2 specific IgG as well as specific T-cell responses were quantified in all participants at two time points: one and six months after complete vaccination. All participates were adults, had been vaccinated twice with Gam-COVID-Vac and had no prior history of confirmed COVID-19.&lt;br /&gt; &lt;b&gt;Results: &lt;/b&gt;In both groups, IgG levels decreased from month one to six, however, antibodies did not decline more rapidly in HD group (analysis of variance p=0.7214 for the “time×group” interaction, non-adjusted model). At the end of the study, 48.0% of non-HD and 67.0% of HD participants showed T-cell positivity. T-spot counts dropped over time in non-HD controls, but not in HD subjects (p=0.0080 and p=0.1800, respectively).&lt;br /&gt; &lt;b&gt;Conclusions: &lt;/b&gt;Patients receiving HD maintain significant long-term humoral response after Gam-COVID-Vac vaccination, which is comparable to that in subjects with normal kidney function. Cellular response turned up to be more sustained over time in HD group.

Anxiety and sleep quality in patients receiving maintenance hemodialysis: multiple mediating roles of hope and family function

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.

Burden of CKD-Associated Pruritus and Adverse Clinical Outcomes in Patients Receiving Dialysis: The Stockholm Creatinine Measurements (SCREAM) Project

Pruritus is a common but not well-characterized complaint of patients receiving maintenance dialysis. This study sought to quantify the burden of pruritus and its associated adverse health outcomes in this population. Observational study. All patients receiving maintenance dialysis in Stockholm, Sweden, during 2005-2021. Clinically recognized pruritus defined using International Classification of Diseases, Tenth Revision codes or a prescription for antipruritus treatments (including UV therapy). All-cause mortality, severe infection-related hospitalizations (composite of endocarditis, peritoneal dialysis-related peritonitis, hemodialysis/peritoneal dialysis-related catheter infection, sepsis due to Staphylococcus spp., or skin infection) and incident diagnoses of anxiety/depression and sleep disorders. Multivariable logistic regression and cause-specific hazards models to analyze factors associated with prevalent and new-onset pruritus, respectively. Multivariable cause-specific hazards models with time-varying exposure were used to explore the association of prevalent and new-onset pruritus with adverse health outcomes. Among 3,281 dialysis recipients (median age, 64 years; 66% men; 69% receiving hemodialysis, 77% with incident dialysis), 456 (14%) had pruritus at enrollment. During a median follow-up of 3.3 (IQR, 1.3-9.2) years, 539 (19%) additional patients experienced pruritus. Older age, female sex, a lower serum albumin level, and higher C-reactive protein, serum calcium, and phosphorus levels were independently associated with pruritus. Compared with patients without pruritus, patients with pruritus were at a higher risk of sleep disorders (adjusted HR, 1.96; 95% CI, 1.60-2.39), developing anxiety/depression (adjusted HR, 1.56; 95% CI, 1.23-1.98), and being hospitalized for severe infections (adjusted HR, 1.36; 95% CI, 1.18-1.57), the latter attributed to higher risk of sepsis and peritoneal dialysis-related peritonitis. There was no detectable association between the development of pruritus and all-cause mortality. Potential misclassification bias if pruritus is not clinically recognized, lack of information on pruritus intensity/severity, use of diagnostic codes for exposure and outcome diagnoses. At least one third of patients experience pruritus during their first years undergoing dialysis, and pruritus was consistently associated with adverse health outcomes. Pruritus is a common but not well-characterized symptom of patients receiving dialysis. We analyzed data from 3,281 patients receiving maintenance hemodialysis or peritoneal dialysis in the region of Stockholm, Sweden. At baseline, 14% of patients had pruritus, and pruritus developed in an additional 19% of patients during their time receiving dialysis. We identified conditions associated with the development of pruritus (eg, older age, female sex, lower serum albumin level, and higher C-reactive protein, serum calcium, and phosphorus levels) and observed that the presence of pruritus was associated with higher risks of sleep disorders, developing anxiety and depression, and being hospitalized for severe infections. No association between pruritus and all-cause mortality was identified.

Expected usefulness of third dose of coronavirus disease 2019 vaccine for immunizing patients receiving maintenance hemodialysis

Expected usefulness of third dose of coronavirus disease 2019 vaccine for immunizing patients receiving maintenance hemodialysis
