RESUMEN

ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12-84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.

RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12-84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19.

RESUMEN

Background: End-stage kidney disease (ESKD) patients often face complications like anemia, malnutrition, and cardiovascular issues. Serological tests, which are uncomfortable and not frequently conducted, assist in medical assessments. A non-invasive, convenient method for determining these test results would be beneficial for monitoring patient health. Objective: This study develops machine learning models to estimate key serological test results using non-invasive cellular bioelectrical impedance measurements, a routine procedure for ESKD patients. Methods: The study employs two machine learning models, Support Vector Machine (SVM) and Random Forest (RF), to determine key serological tests by classifying cell bioelectrical indicators. Data from 688 patients, comprising 3,872 biochemical-bioelectrical records, were used for model validation. Results: Both SVM and RF models effectively categorized key serological results (albumin, phosphorus, parathyroid hormone) into low, normal, and high. RF generally outperformed SVM, except in classifying calcium levels in women. Conclusion: The machine learning models effectively classified serological test results for maintenance hemodialysis patients using cellular bioelectrical indicators, therefore can help in making judgments about physicochemical indicators using electrical signals, thereby reducing the frequency of serological tests.

RESUMEN

OBJECTIVES: Disparity in kidney transplant access has been demonstrated by a disproportionately low rate of kidney transplantation in socioeconomically disadvantaged patients. However, the information is not from national representative populations with end-stage kidney disease (ESKD). We aim to examine whether socioeconomic disparity for kidney transplant access exists by utilizing data from the All of Us Research Program. MATERIALS AND METHODS: We analyzed data of adult ESKD patients using the All of Us Researcher Workbench. The association of socioeconomic data including types of health insurance, levels of education, and household incomes with kidney transplant access was evaluated by multivariable logistic regression analysis adjusted by baseline demographic, medical comorbidities, and behavioral information. RESULTS: Among 4078 adults with ESKD, mean diagnosis age was 54 and 51.64% were male. The majority had Medicare (39.6%), were non-graduate college (75.79%), and earned $10 000-24 999 annual income (20.16%). After adjusting for potential confounders, insurance status emerged as a significant predictor of kidney transplant access. Individuals covered by Medicaid (adjusted odds ratio [AOR] 0.45; 95% confidence interval [CI], 0.35-0.58; P-value < .001) or uninsured (AOR 0.21; 95% CI, 0.12-0.37; P-value < .001) exhibited lower odds of transplantation compared to those with private insurance. DISCUSSION/CONCLUSION: Our findings reveal the influence of insurance status and socioeconomic factors on access to kidney transplantation among ESKD patients. Addressing these disparities through expanded insurance coverage and improved healthcare access is vital for promoting equitable treatment and enhancing health outcomes in vulnerable populations.

RESUMEN

AIMS: Angiotensin receptor-neprilysin inhibitor (ARNI) has played an increasingly important role in the management of heart failure (HF). However, the evidence on the benefits of ARNI in HF patients with end-stage kidney disease (ESKD) undergoing dialysis is limited. This study aimed to investigate the efficacy and safety of ARNI in patients with concomitant HF and ESKD on maintenance dialysis. METHODS AND RESULTS: We systematically searched the MEDLINE, Embase, Web of Science, Cochrane, and ClinicalTrials.gov databases for studies reporting outcomes after ARNI treatment in HF patients with ESKD on dialysis. All meta-analyses were performed using the random effects model. Twenty-six studies comprising 2494 patients with concomitant HF and ESKD undergoing dialysis were included. Our synthesis showed a significant improvement in left ventricular ejection fraction (LVEF) between before and after ARNI treatment (mean change: 8.05%; 95% confidence interval [CI] 5.57-10.54). Compared to the conventional group, the ARNI group showed a greater improvement in LVEF (mean difference: 4.03%; 95% CI 2.90-5.16). This effect was more pronounced in patients with HF with reduced ejection fraction (pinteraction < 0.0001). Patients treated with ARNI had a lower risk of all-cause mortality (risk ratio [RR] 0.64; 95% CI 0.45-0.92; p = 0.01) but had a similar rate of HF hospitalization (RR 0.71; 95% CI 0.43-1.18; p = 0.19). ARNI treatment showed benefits in the improvement of left ventricular end-systolic diameter, left ventricular mass index, left atrial diameter, and E/e' ratio (p < 0.05), while it did not significantly increase the risk of severe hyperkalaemia (p = 0.33) or symptomatic hypotension (p = 0.53). CONCLUSION: This meta-analysis provided insights into the benefits of ARNI in HF patients with ESKD undergoing dialysis by improving left ventricular function, reversing left ventricular remodelling, and reducing the risk of all-cause mortality, without increasing the risk of HF hospitalizations, severe hyperkalaemia, and symptomatic hypotension.

RESUMEN

Through a quality improvement project, we developed an initiative that leveraged patient- and community-level data to address health disparities and social vulnerability among patients receiving outpatient dialysis, including both incenter and home modalities. Using the Area Deprivation Index, we identified patients living in areas with the highest levels of deprivation and developed targeted interventions to help address adverse social determinants of health to improve patient health outcomes. Our quality improvement project demonstrates the potential of data-driven ap - proaches to identify and address health disparities in outpatient dialysis, and highlights the importance of addressing social determinants of health in improving patient outcomes.

RESUMEN

Rationale & Objective: The development of anuria has been linked to worse clinical outcomes in patients undergoing peritoneal dialysis (PD). Our objective was to investigate the incidence, risk factors, and associated clinical outcomes of anuria within the first year after starting PD. Study Design: Retrospective cohort study. Setting & Participants: Patients who started continuous ambulatory peritoneal dialysis at our center between 2006 and 2020 were included and followed up until January 31, 2023. Exposure: Age, sex, diabetes, temporary hemodialysis, angiotensin-converting enzyme inhibitors (ACEis) or angiotensin II receptor blockers (ARBs), diuretics, baseline urine volume, serum albumin, daily glucose exposure, peritonitis, and incremental PD. Outcomes: The primary outcome was early anuria, defined as 24-hour urine volume ≤100 mL within the first year of PD initiation. Secondary outcomes included all-cause mortality, cardiovascular disease mortality, technique failure, and peritonitis. Analytical Approach: Cox proportional hazards model. Results: A total of 2,592 patients undergoing continuous ambulatory peritoneal dialysis aged 46.7 ± 14.9 years were recruited. Among them, 58.9% were male, and 24.0% had diabetes. Within the first year of PD therapy, 159 (6.13%) patients developed anuria, with a median duration of 7.53 (interquartile range, 3.93-10.0) months. Higher baseline urine volume (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.90-0.97), higher serum albumin (HR, 0.92; 95% CI, 0.88-0.95), having diabetes before PD (HR, 0.57; 95% CI, 0.35-0.92), and prescribed incremental PD (HR, 0.27; 95% CI, 0.14-0.51) were associated with a reduced risk for early anuria, whereas a higher level of daily glucose exposure (HR, 1.01; 95% CI, 1.00-1.01) was identified as a risk factor for early anuria. Subgroup analyses showed that using ACEis or ARBs was linked to a lower risk of early anuria (HR, 0.25; 95% CI, 0.09-0.69) in diabetic patients. Treating early anuria as a time-dependent covariate, early anuria was associated with a higher risk for all-cause mortality (HR, 1.69; 95% CI, 1.23-2.32) and technique failure (HR, 1.43; 95% CI, 1.00-2.04) after adjusting for confounding factors. Limitations: Single-center and observational study. Conclusions: Among PD patients at a single center in China, early anuria was relatively uncommon but associated with an increased risk of mortality and PD technique failure. Incremental PD, higher baseline urine output and serum albumin, and lower daily glucose exposure were associated with a lower risk of early anuria. Clinical trials are needed to evaluate the optimal PD techniques to preserve residual kidney function and maximaze outcomes.

The development of anuria has been linked to worse clinical outcomes in patients undergoing peritoneal dialysis (PD). However, does the development of early anuria, which is defined as 24-hour urine volume ≤100 mL, within the first year after PD initiation influence the clinical outcomes of these patients? What are the predictors of early anuria? We conducted a single-center retrospective cohort study and found lower baseline urine volume, lower serum albumin, full-dose PD start, absence of diabetes mellitus, higher daily glucose exposure, and in patients with diabetes mellitus, non-use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers were associated with early anuria. Early anuria was related to a higher risk for all-cause mortality and technique failure. The results provide information for optimizing patient care and improving the prognosis of patients undergoing PD.

RESUMEN

BACKGROUND AND AIMS: The potential impact of peripheral artery disease (PAD) on kidney outcomes is not well understood. The aim of this study was to explore the association between PAD and end-stage kidney disease (ESKD) and chronic kidney disease (CKD). METHODS: Among 14,051 participants (mean age 54 [SD 6 years]) from the Atherosclerosis Risk in Communities study, we categorized PAD status as symptomatic PAD (intermittent claudication or leg revascularization), asymptomatic PAD (ankle-brachial index [ABI] ≤0.90 without clinical history of symptoms), and ABI 0.91-1.00, 1.01-1.10, 1.11-1.20 (reference), 1.21-1.30, and >1.30. We evaluated their associations with two kidney outcomes: ESKD (the need of renal replacement therapy or death due to kidney disease) and CKD (ESKD cases or an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 with a ≥25 % decline from the baseline) using multivariable Cox proportional hazards models. RESULTS: Over ∼30 years of follow-up, there were 598 cases of incident ESKD and 4686 cases of incident CKD. After adjusting for potential confounders, both symptomatic PAD and asymptomatic PAD conferred a significantly elevated risk of ESKD (hazard ratio 2.28 [95 % confidence interval 1.23-4.22] and 1.75 [1.19-2.57], respectively). Corresponding estimates for CKD were 1.54 (1.14-2.09) and 1.63 (1.38-1.93). Borderline low ABI 0.91-1.00 also showed elevated risk of adverse kidney outcomes after adjustment for demographic variables. Largely consistent results were observed across demographic and clinical subgroups. CONCLUSIONS: Symptomatic PAD and asymptomatic PAD were independently associated with an elevated risk of ESKD and CKD. These results highlight the importance of monitoring kidney function in persons with PAD, even when symptoms are absent.

RESUMEN

BACKGROUND: End-stage kidney disease (ESKD) patients are prone to bloodstream infections which may result in a higher risk of cardiac implantable electronic device (CIED) infections. OBJECTIVE: To assess the incidence, risk predictors, management strategies and long-term outcomes of CIED infections in ESKD patients undergoing de-novo CIED implantation. METHODS: This is a retrospective study utilizing the United States Renal Data System. ESKD patients with de-novo CIED implant between 1/1/2006-9/30/2014 were included. Patients were followed until death, kidney transplantation, end of Medicare coverage or 9/30/2015 to assess incidence of CIED infection. Management approach was determined from procedure codes for lead extraction within 60 days of CIED infection diagnosis. Patients with CIED infection were followed until 12/31/2019 to assess long-term outcomes. RESULTS: Among 15,515 ESKD patients undergoing de-novo CIED implant, incidence of CIED infection was 4.8% over a median follow-up of 1.3 years. The presence of a defibrillator (aHR 1.48), higher BMI (aHR 1.01), younger age (aHR 0.96) were independent risk factors for CIED infection. Lead extraction occurred in only 50.71% patients by 60 days. After propensity score matching, the 3-year mortality was higher in those who did not undergo lead extraction compared to those who did (80.3% vs 72.3%) and time to mortality was shorter (0.3 vs 0.6 years). Only 13.8% patients underwent reimplantation with a new CIED after lead extraction. CONCLUSION: CIED infections occur frequently in ESKD patients and are associated with a very high mortality. Early lead extraction is not performed routinely but is associated with improved survival.

RESUMEN

Background: Chronic kidney disease (CKD) and end-stage renal disease (ESKD) are significant global health challenges associated with progressive kidney dysfunction and numerous complications, including cardiovascular disease and mortality. This study aims to explore the potential association between plasma klotho levels and various prognostic outcomes in CKD and ESKD, including all-cause mortality, cardiovascular events, metabolic syndrome development and adverse renal events necessitating renal replacement therapies. Methods: A literature search was conducted through 3 June 2024 using the electronic databases Cochrane Library, Ovid MEDLINE, CINAHL, Web of Science, SCOPUS and PubMed. This systematic review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Fourteen studies were included. For all-cause mortality, comparing CKD patients with low versus high klotho levels showed a significant association {odds ratio [OR] 1.81 [95% confidence interval (CI) 1.34-2.44], P = .0001}, with substantial heterogeneity (I 2 = 69%). Excluding one study reduced heterogeneity (I 2 = 43%) while maintaining significance [OR 1.97 (95% CI 1.45-2.66), P < .0001]. Cardiovascular mortality was higher in patients with low klotho levels [OR 2.11 (95% CI 1.61-2.76), P < .00001], with low heterogeneity (I 2 = 25%). Excluding one study eliminated heterogeneity (I 2 = 0%) while maintaining significance [OR 2.39 (95% CI 1.83-3.12), P < .00001]. Composite cardiovascular events did not differ significantly between low and high klotho groups [OR 1.51 (95% CI 0.82-2.77), P = .18], but with high heterogeneity (I 2 = 72%). Patients with low klotho levels had a higher risk of adverse renal events [OR 2.36 (95% CI 1.37-4.08), P = .002], with moderate heterogeneity (I 2 = 61%). Sensitivity analysis reduced heterogeneity (I 2 = 0%) while maintaining significance [OR 3.08 (95% CI 1.96-4.85), P < .00001]. Specifically, for ESKD or kidney replacement therapy risk, low klotho levels were associated with an increased risk [OR 2.30 (95% CI 1.26-4.21), P = .007]. Similarly, CKD progression risk was higher in patients with lower klotho levels [OR 2.48 (95% CI 1.45-4.23), P = .0009]. Conclusion: Lower serum klotho levels serve as a significant predictor of adverse outcomes, including increased risks of all-cause mortality, cardiovascular mortality and progression to end-stage kidney disease among CKD patients.

RESUMEN

5wPatients with end stage kidney disease (ESKD) who receive in-center hemodialysis are disproportionately vulnerable to extreme weather events, including hurricanes and heat waves, that may disrupt access to healthcare providers, and life-sustaining treatments. This current era of climate-driven compounding disasters is progressively elevating the level of threat to the health and well-being of patients with ESKD. This analysis brings together multi-disciplinary expertise to explore the contours of this increasingly complex risk landscape. Despite the challenges, important advances have been made for safeguarding this medically high-risk patient population. Hemodialysis services providers have devised innovative systems for preparing their patients and sustaining, or rapidly reestablishing, hemodialysis services in the aftermath of a disaster, and maintaining open lines of communication with their caseloads of ESKD patients throughout all phases of the event. A description of lessons learned along the path towards improved patient support in disasters, is provided. The article concludes with a detailed case example, describing dialysis providers' effective response throughout Hurricane Ian's passage across the State of Florida in 2022. Based on lessons learned, this analysis outlines strategies for protecting patients with ESKD that may be adapted for future climate-potentiated disaster scenarios.

RESUMEN

BACKGROUND: Intraperitoneal pressure measurement offers therapeutic and prognostic benefits in predicting leak risks and gastrointestinal symptoms in Peritoneal Dialysis (PD) patients. This systematic review aims to evaluate the prognostic utility of intraperitoneal pressure measurements and different estimated intraperitoneal pressure equations in predicting the risk of non-infectious complications in PD patients. METHODS: Databases including MEDLINE, EMBASE and Cochrane were searched up to July 2023. Randomised and non-randomised trials were included, focusing on End-Stage Kidney Disease (ESKD) patients undergoing PD. Primary outcomes were variables associated with intraperitoneal pressure, while secondary outcomes included PD-related non-infectious complications and gastrointestinal symptoms. Data synthesis combined meta-analysis with narrative synthesis. This review has been registered on PROSPERO (CRD42023475138). RESULTS: Out of 1828 identified studies, 12 were included for systematic review and 10 for meta-analysis. Body Mass Index (BMI) and Body Surface Area (BSA) showed a consistent positive correlation with intraperitoneal pressure (BMI: r = 0.49, 95% CI 0.35-0.61, I2 = 67.39%, p = 0.003; BSA: r = 0.2, 95% CI 0.08-0.31, I2 = 14.10%, p = 0.324). Conversely, the association between intraperitoneal pressure and age, intraperitoneal volume, and Charlson Comorbidity Index were less consistent. Subgroup analysis demonstrated an association between higher intraperitoneal pressure in patients with increased BMI and BSA. However, the relationship between intraperitoneal pressure and non-infectious mechanical complications remained inconclusive. DISCUSSION: This review underscores a significant association between intraperitoneal pressure and anthropometric measures (BMI and BSA). The majority of the studies identified included a small sample and considerable bias. However, the association between intraperitoneal pressure and clinically relevant outcomes was not clear. CONCLUSIONS: While increasing body mass index and body surface areas are associated with increasing intraperitoneal pressure, the clinical relevance of measuring intraperitoneal pressure in an adult population remains unclear, particularly given the absence of an association with clinically relevant non-infectious outcomes.

RESUMEN

BACKGROUND: American Indian/Alaska Natives (AI/ANs) disproportionately suffer from diabetes compared to non-Hispanic whites (NHW). In 2013, 69% of end-stage kidney disease (ESKD) in AI/ANs was caused by diabetes (ESKD-D) but accounts for only 44% of ESKD diagnoses in the overall USA population. Moreover, the diagnosis of diabetes and ESKD-D may be significantly related to social determinants of health. The purpose of this study was to conduct a survival analysis of AI/ANs and NHWs diagnosed with ESKD-D nationally and by Indian Health Service region and correlate the survival analysis to the Area Deprivation Index® (ADI®). METHODS: This manuscript reports a retrospective cohort analysis of 2021 United States Renal Data System data. Eligible patient records were AI/AN and NHWs with diabetes as the primary cause of ESKD and started dialysis on January 1, 2014, or later. RESULTS: A total of 81,862 patient records were included in this analysis, of which 1798 (2.2%) were AI/AN. AI/ANs survive longer, with an 18.4% decrease in risk of death compared to NHW. However, AI/ANs are diagnosed with ESKD-D and start dialysis earlier than NHWs. ADI® variables became significant as ADI® ratings increased, meaning persons with greater social disadvantage had worse survival outcomes. CONCLUSIONS: The findings reveal that AI/ANs have better survival outcomes than NWH, explained in part by initiating dialysis earlier than NHW. Additional research is needed to explore factors (e.g., social determinants; cultural; physiologic) that contribute to earlier diagnosis of ESKD-D in AI/ANs and the impact of prolonged dialysis on quality of life of those with ESKD-D.

RESUMEN

The increasing prevalence of diabetes has led to a growing population of end-stage kidney disease (ESKD) patients with diabetes. Currently, kidney transplantation is the best treatment option for ESKD patients; however, it is limited by the lack of donors. Therefore, dialysis has become the standard treatment for ESKD patients. However, the optimal dialysis method for diabetic ESKD patients remains controversial. ESKD patients with diabetes often present with complex conditions and numerous complications. Furthermore, these patients face a high risk of infection and technical failure, are more susceptible to malnutrition, have difficulty establishing vascular access, and experience more frequent blood sugar fluctuations than the general population. Therefore, this article reviews nine critical aspects: Survival rate, glucose metabolism disorder, infectious complications, cardiovascular events, residual renal function, quality of life, economic benefits, malnutrition, and volume load. This study aims to assist clinicians in selecting individualized treatment methods by comparing the advantages and disadvantages of hemodialysis and peritoneal dialysis, thereby improving patients' quality of life and survival rates.

RESUMEN

Contraception, pregnancy and fertility are seldom discussed with women receiving dialysis and the medical staff of dialysis centres. Since the majority of women on dialysis are past childbearing age, these themes are not always given proper consideration and this category of patients may be missing important information. Young women of childbearing age who are on dialysis frequently experience sexual dysfunction and hormonal disorders of the hypothalamic-pituitary-gonadal axis. In addition, dialysis often has a relevant psychological impact and affects the person's social role. Physical changes may accompany kidney failure, including the presence of a vascular or peritoneal access. The dialysis ward is not a place that facilitates privacy, and discussing contraception is not always easy, particularly in some cultural contexts, or between a male doctor and a young woman. While pregnancy and contraception are routinely addressed with women waiting for a kidney transplant, they are less frequently discussed with women on dialysis. Numerous studies have found that over half of the pregnancies in women on dialysis are unplanned. How frequently patients are seen (at each dialysis session, or during periodic visits) does not necessarily make things better, as often some issues are taken for granted or discussing them is postponed. In our centre, over 160 patients are on chronic hemodialysis (HD) and 20 are on peritoneal or home HD. Only nine women were of childbearing age in our center, all on HD. We discussed with them on counselling about pregnancy, and to ensure that all women of childbearing age would be offered counselling on contraception and pregnancy, we designed simple leaflets and an infographic, in collaboration with our nursing team and residents, as a guide and a reminder for our staff to discuss these topics with the patients.

RESUMEN

Estimated glomerular filtration rate (eGFR) variation is associated with end-stage kidney disease (ESKD) development in patients with chronic kidney disease; whether annual variations in eGFR at health check-ups is associated with ESKD risk in the general population is unclear. We conducted a retrospective cohort study using Japanese national medical insurance claims from 2013 to 2020. Individuals who had their eGFR levels measured three times in annual health check-ups were included (N = 115,191), and the coefficient of variation of eGFR (CVeGFR) was calculated from 3-point eGFR. The end-point was ESKD as reported in the claims data. We analyzed the association between CVeGFR and ESKD incidence after adjusting for conventional ESKD risk factors. The CVeGFR median distribution was 5.7% (interquartile range: 3.5-8.5%). During a median follow-up period of 3.74 years, 164 patients progressed to ESKD. ESKD incidence was significantly higher in the highest quartile group (CVeGFR ≥ 8.5%) than in the other groups (P < 0.0001). After adjusting for risk factors, individuals with CVeGFR ≥ 8.5% had a significantly high ESKD incidence (adjusted hazard ratio: 3.01; 95% CI 2.14-4.30). High CVeGFR in annual health check-ups was associated with high ESKD incidence, independent of its other conventional risk factors, in the general population.

RESUMEN

OBJECTIVE: Characterize the health-related quality of life among patients undergoing kidney replacement therapy and to explore associated factors. METHOD: A descriptive observational study was conducted using the Kidney Disease Quality of Life Short Form questionnaire to assess health-related quality of life. The Dader Method was employed to evaluate negative outcomes associated with medications. Face-to-face interviews and clinical records were utilized to collect sociodemographic and clinical data from patients undergoing kidney replacement therapy at the Nephrology Department of Virgen de las Nieves University Hospital (Granada, Spain). We explored the association between independent variables (clinical and demographic factors) and dependent variables (Mental Component Score and Physical Component Score) using the linear regression method. RESULTS: Ninety-one participants were included, 47 (48.35%) were females. The mean age was 62 years, 52 patients (57.14%) were on hemodialysis, 13 patients (14.29%) on peritoneal dialysis, and 26 patients (28.57%) on other forms of kidney replacement therapy. The study revealed a mean Physical Component Score of 40.89 and a Mental Component Score of 47.19. Additionally, 98.90% of the patients experienced negative outcomes associated with medications. Influential factors include age, comorbid conditions, the number of medications, and clinical parameters such as vitamin D and calcium levels. CONCLUSIONS: This study underscores significant findings in patients undergoing kidney replacement therapy, indicating low Mental Component Score and Physical Component Score, accompanied by negative outcomes associated with medications.

RESUMEN

Background: Valvular calcification (VC) refers to the calcified valvular remodeling associated with kidney dysfunction, especially end-stage kidney disease (ESKD). ESKD patients with VC had significantly higher cardiovascular risk than those without. Factors interacted with VC regarding prognostic prediction in this population were seldom investigated. We aimed to examine the potential synergetic effects of VC and alkaline phosphatase (Alk-P) on ESKD patients' cardiovascular risk and mortality. Methods: ESKD patients undergoing hemodialysis were prospectively enrolled from a medical center in 2018. We identified patients with echocardiography and available serum Alk-P levels. Cox proportional hazard regression was performed to analyze the risk of major adverse cardiovascular events (MACEs), cardiovascular and overall mortality among 4 participant groups (with or without VC versus low or high Alk-P levels). The models were further adjusted for age, sex, and clinical variables. Results: Of the 309 ESKD patients, 38, 46, 112, and 113 had no VC with low Alk-P, no VC with high Alk-P, VC with low Alk-P, and VC with high Alk-P, respectively. After adjusting for age and sex, patients with VC and high Alk-P had a higher risk of developing MACE, cardiovascular and overall mortality (HR, 3.07, 3.67, 3.65; 95% CI 1.38-6.84, 1.1-12.24, 1.29-10.36, respectively). Patients with VC and high Alk-P remained at higher risk of MACE (HR, 2.76; 95% CI 1.17-6.48) than did those without VC and with low Alk-P. Conclusion: Serum Alk-P could be used to identify a subgroup of ESKD patients with elevated cardiovascular risk among those with VC.

RESUMEN

OBJECTIVES: Obesogenic medications are a putative contributor to the obesity epidemic. While 20% of adults take ≥1 obesogenic medication, the proportion in the end-stage kidney disease (ESKD) population-a group enriched for cardiometabolic complications-is unknown. Obesogenic medications may contribute to obesity and hamper weight loss efforts to achieve transplant listing. METHODS: Using 2017-2020 USRDS and Medicare claims, patients were identified as taking obesogenic medications if prescribed anticonvulsants, antidepressants, antidiabetics, anti-inflammatories, antipsychotics, and/or antihypertensives known to cause weight gain for ≥30 days in their first hemodialysis year. Ordinal logistic and Cox regression with inverse probability of treatment weighting were used to quantify obesogenic medications' association with body mass index (BMI) and listing, respectively. RESULTS: Among 271 401 hemodialysis initiates, 63.5% took ≥1 obesogenic medication. For those in underweight, normal weight, overweight, and class I, II, and III categories, 54.3%, 58.4%, 63.1%, 66.5%, 68.6%, and 68.8% took ≥1, respectively. Number of obesogenic medications was associated with increased BMI; use of one was associated with 13% increased odds of higher BMI (aOR [adjusted odds ratio] 1.14; 95%CI: 1.13-1.16; p < 0.001), use of three was associated with a 55% increase (aOR 1.55; 95%CI: 1.53-1.57; p < 0.001). Any use was associated with 6% lower odds of transplant listing (aHR [adjusted hazard ratio] 0.94; 95%CI: 0.92-0.96; p < 0.001). Within each BMI category, obesogenic medication use was associated with lower listing likelihood. CONCLUSIONS: Obesogenic medication use is common in ESKD patients-particularly those with obesity-and is associated with lower listing likelihood. Whenever possible, non-obesogenic alternatives should be chosen for ESKD patients attempting weight loss to achieve transplant listing.

RESUMEN

BACKGROUND: Family caregivers, mostly parents, are greatly involved in the care of their children with end stage kidney disease (ESKD) globally. Yet, the experiences of these caregivers and the demands placed on them by the caregiving role have not been explored or documented in Ghana. This study explored how caregiving affects the psychological, physical, social, and spiritual well-being of family caregivers of children with end stage kidney disease (ESKD) in Ghana. METHODS: A phenomenological approach with the purposive sampling technique was used to gather data from 12 family caregivers of children with ESKD at a pediatric renal unit in Ghana. A semi-structured interview guide was constructed based on the constructs of the City of Hope Quality of Life (QoL) Family Caregiver Model and the research objectives. Colaizzi's thematic analysis approach was utilized to analyze data for this study. Themes were organized under the domains of the chosen model, and a new theme outside these domains was also generated. RESULTS: The majority of the family caregivers experienced anxiety, fear, uncertainty, and hopelessness in response to the children's diagnosis and care. The thought of the possibility of the children dying was deeply traumatizing for our participants. Most participants reported bodily pains and physical ailments because of lifting and caring for the children. Financial constraint was also a key issue for all the family caregivers. Most of them received diverse support from their families and loved ones. Due to the demanding nature of the care, most family caregivers had to change or quit their jobs. They coped with the challenges through prayers, participating in religious activities, and being hopeful in God for healing. CONCLUSION: All the family caregivers had their psychological well-being compromised as a result of the challenges they encountered physically, socially, and spiritually. Continuous psychosocial support, funding support, and review of policies on leave for civil workers with children diagnosed with ESKD are urgently required.
