RESUMO

ABSTRACT: Intradialytic hypotension (IDH) may lead to a poor life quality and was associated with cardiovascular mortality in patients under hemodialysis. This study investigated the autonomic nerve and cardiovascular function in the IDH episodes.In this case-control study, 70 end stage renal disease patients (198 visits) were recruited. Pulse wave analysis and heart rate variability were evaluated before hemodialysis. Two definitions of IDH were confirmed by medical records. IDH-f indicated a drop of systolic blood pressure or mean arterial pressure, accompanied with symptoms; IDH-n indicated a low nadir systolic pressure during the hemodialysis. All parameters were evaluated for the possible predisposing factors under each definition.A total of 24 IDH-f and 37 IDH-n were noted in 177 visits. For both definitions, central pulse pressure seemed to be a consistent predisposing factor. Furthermore, lower sympathetic activity (odds ratio [OR] 0.55; 95% confidence interval [CI] 0.35-0.87), lower pulse pressure (OR 0.95; 95% CI 0.92-0.98), and higher augmentation index (OR 17.36; 95% CI 1.48-204.10) were the possible predisposing factors for IDH-f. On the contrary, lower mean arterial pressure (OR 0.87; 95% CI 0.78-0.98) was identified as the possible factor for IDH-n.It was suggested that the lower central pulse pressure and sympathetic activity might be involved in the development of IDH.

RESUMO

The new coronavirus disease (Covid-19) pandemic in Italy formally started on 21st February 2020, when a 38-years old man was established as the first Italian citizen with Covid-19 in Codogno, Lombardy region. In a few days, the deadly coronavirus swept beyond expectations across the city of Bergamo and its province, claiming thousands of lives and putting the hospital in Treviglio under considerable strain. Since designated Covid-dialysis hospitals to centrally manage infected hemodialysis patients were not set up in the epidemic areas, we arranged to treat all our patients. We describe the multiple strategies we had to implement fast to prevent/control Covid-19 infection and spread resources in our Dialysis Unit during the first surge of the pandemic in one of the worst-hit areas in Italy. The recommendations provided by existing guidelines and colleagues with significant experience in dealing with Covid-19 were combined with the practical judgement of our dialysis clinicians, nurses and nurse's aides.

RESUMO

OBJECTIVE: Kidney transplant is the treatmentof election of end-stage chronic renal disease, usually being heterotopic extraperitoneal in the iliac fossae, with successful results. This technique can be challenging or even not feasible, usually in cases of severe vasculopathy or previous grafts, so urologists should consider alternatives such as orthotopic transplant. MATERIAL AND METHODS: We present three cases oforthotopic kidney transplant (OKT) made in Cruces University Hospital from 2001 to 2019, out of 2580 cases. We review recipients' medical history, indication,surgical technique and post surgical evolution. RESULTS: The average age of the patients was 51.6 years. The indication was severe vasculopathy of iliac vessels. We made left nephrectomy, followed by venous renal end-to-end anastomosis, arterial end-to-side anastomosis to aorta and pyelo-pyelic anastomosis with catheter,with immediate function of the graft. The patients' evolution was favourable, without significant complications and no differences with heterotopic transplant. CONCLUSION: OKT is a good alternative when heterotopicis not feasible, with an acceptable number of complications and similar survival.

RESUMO

Early in the coronavirus-2019 (COVID-19) containment strategy, people with end-stage renal disease (ESRD) were identified as extremely clinically vulnerable and subsequently asked to 'shield' at home where possible. The aim of this study was to investigate how these restrictions and the transition to an increased reliance on telemedicine within clinical care of people living with kidney disease impacted the physical activity (PA), wellbeing and quality of life (QoL) of adults dialysing at home (HHD) or receiving in-centre haemodialysis (ICHD) in the UK. Individual semistructured telephone interviews were conducted with adults receiving HHD (n = 10) or ICHD (n = 10), were transcribed verbatim and, subsequently, thematically analysed. As result of the COVID-19 restrictions, PA, wellbeing and QoL of people with ESRD were found to have been hindered. However, widespread support for the continued use of telemedicine was strongly advocated and promoted independence and satisfaction in patient care. These findings highlight the need for more proactive care of people with ESRD if asked to shield again, as well as increased awareness of safe and appropriate PA resources to help with home-based PA and emotional wellbeing.

RESUMO

Red blood cells (RBCs) have been found to synthesize and release both nitric oxide (NO) and cyclic guanosine monophosphate (cGMP), contributing to systemic NO bioavailability. These RBC functions resulted impaired in chronic kidney disease (CKD). This study aimed to evaluate whether predialysis (conservative therapy, CT) and dialysis (peritoneal dialysis, PD; hemodialysis, HD) therapies used during CKD progression may differently affect NO-synthetic pathway in RBCs. Our data demonstrated that compared to PD, although endothelial-NO-synthase activation was similarly increased, HD and CT were associated to cGMP RBCs accumulation, caused by reduced activity of cGMP membrane transporter (MRP4). In parallel, plasma cGMP levels were increased by both CT and HD and they significantly decreased after hemodialysis, suggesting that this might be caused by reduced cGMP renal clearance. As conceivable, compared to healthy subjects, plasma nitrite levels were significantly reduced by HD and CT but not in patients on PD. Additionally, the increased carotid intima-media thickness (IMT) values did not reach the significance exclusively in patients on PD. Therefore, our results show that PD might better preserve the synthetic NO-pathway in CKD-erythrocytes. Whether this translates into a reduced development of uremic vascular complications requires further investigation.

RESUMO

Fabry disease is a rare X-linked hereditary storage disease caused by a mutation of the gene encoding alpha-galactosidase A. The clinical manifestation of the classical disease form is variable depending on the degree of individual organs involvement, including especially kidney, myocardium, central nervous system (CNS) and skin. We report a case of a 51-year-old man whose diagnostic manifestation was cardiac involvement leading to endomyocardial biopsy, which significantly contributed to the diagnosis. Although at that time he was already 9 years dependent on dialysis with terminal renal failure.

RESUMO

BACKGROUND: End-stage renal disease (ESRD) is associated with alterations in T-cell immunity, including increased CD28null and reduced regulatory T cells (Tregs). However, whether immune disturbances are due to ESRD or primary disease is not yet clear. As diabetes mellitus is the leading cause of ESRD, we evaluated its impact on the immune profile of ESRD patients. METHODS: CD28null, Tregs, and natural killer cells were initially analyzed by flow cytometry in 30 predialysis ESRD patients due to diabetes (DM), 30 non-DM (NDM), and 25 healthy controls. Measurements were repeated after 6 months on hemodialysis (HD) or peritoneal dialysis (CAPD). RESULTS: The percentage of CD4 + CD28null cells, CD8 + CD28null cells, and Tregs showed significant differences in DM, NDM, and controls; mean rank 33.71 vs. 25.68 vs. 18.88, p = 0.006, 37.79 vs. 28.82 vs. 17.08, p = 0.008, and 20.79 vs. 26.12 vs. 41.33, p = 0.001, respectively. DM vs. NDM had increased CD4 + CD28null and CD8 + CD28null cells, 11.5% (1.5%-24%) vs. 4.1% (0-42.3%), p = 0.02 and 61.3% (24%-76%) vs. 43% (5.7%-85%), p = 0.04, respectively. After 6 months on HD but not CAPD, DM showed a significant further increase in CD4 + CD28null cells, from 30 (14-100) to 52.7 (15-203), p = 0.02; and CD8 + CD28null cells, from 137 (56-275) to 266 (103-456), p = 0.01. CONCLUSIONS: Diabetes mellitus affects T-cell subtypes even at predialysis stage, though changes become more prominent after commencement on HD.

RESUMO

Cardiovascular disorders represent the leading cause of death in dialysis patients. Alterations of bone and mineral metabolism (BMM) and vascular calcifications play a fundamental role in it. The objective of this study was to evaluate the predictive role on cardiovascular mortality of the measurement of biomarkers of BMM and vascular calcifications. A prospective cohort study was performed. All prevalent patients on chronic dialysis in September 2009 at our institution, who completed the total of the complementary studies, were studied. BMM biomarkers were measured (FGF 23, fetuin A, PTH, calcium and phosphorus) and the vascular calcifications were evaluated using the Kauppila and Adragao scores. Follow-up was carried out until 1/1/2019, death or transplant. Of the 30 patients included, 7 (23.3%) died due to cardiovascular causes. The follow-up time was 44.1 ± 30.4 (range = 1.4-112) months. The Adragao score was the only predictive variable of long-term cardiovascular mortality (area under the curve = 0.82; 95% CI 0.64-0.94; p < 0.001). The best cut-off point was 5 (sensitivity = 85.7%; specificity = 78.3%). It was also an independent risk factor for cardiovascular mortality adjusted for age, diabetes mellitus, coronary heart disease, aortic calcifications, time spent on dialysis and follow-up time (adjusted OR = 1.77; 95% CI = 1.06-2.96; p = 0.028). The vascular calcifications quantified from the Adragao score were the only independent predictor of long-term cardiovascular mortality. This score represents a simple, useful and superior tool to the biomarkers of BMM.

RESUMO

This article describes an experience providing nursing care to a patient under hemodialysis with the end-stage renal disease who had developed depression, loathing, and other, negative personal perceptions and gradually gave up on life goals due to hopelessness. The duration of nursing care, from August 23rd through August 29th, 2019, was revisited to identify the patient`s hopelessness in the dimensions of physiology, mental status, society, and spirituality. The author applied Swanson`s Caring Theory to facilitate the process of "knowing" and "being with" while performing direct nursing care and attentive listening to assist the patient to become more open-minded and to express personal perceptions toward the disease with the goal of further engaging the patient to increase self-awareness recognition, sense of loss, and negative perceptions. Through "doing for" and "enabling," the author reinforced infection control and identified the symptoms of fluid-overload, moisture, and salinity to raise the patient`s self-awareness and self-caring techniques and to lower the risk of hospitalization. Meanwhile, by "maintaining the patient`s belief," accompanied by the encouragement and attention from family members and providing linkages to patient-support communities, the patient was guided to identify and aggregate to foster positive thinking and self-worth to increase acceptance of living with the disease. Nursing personnel may apply Swanson`s Caring Theory to better consider the patient`s perspective, provide individual caring schemes, and strengthen the recognition, self-caring techniques and supportive systems of patients, increasing patient perceptions of self-worth, restoring their confidence, promoting their adaption to their disease, and improving attentiveness.

RESUMO

Hemodialysis is the most common type of treatment for end-stage renal disease (ESRD). Frailty is associated with poor outcomes such as higher mortality. ESRD patients have a higher prevalence of frailty. This systematic review and meta-analysis aimed to identify the prevalence and associated factors of frailty and examine whether it is a predictor of mortality among ESRD patients undergoing hemodialysis. Five electronic databases including PubMed, Embase, CINAHL, Web of Science, and Cochrane Library were searched for relevant studies up to 30 November 2020. A total of 752 articles were found, and seven studies with 2604 participants in total were included in the final analysis. The pooled prevalence of frailty in patients with ESRD undergoing hemodialysis was 46% (95% Confidence interval (CI) 34.2-58.3%). Advanced age, female sex, and the presence of diabetes mellitus increased the risk of frailty in ESRD patients undergoing hemodialysis. Our main finding showed that patients with frailty had a greater risk of all-cause mortality compared with those without (hazard ratio (HR): 2.02, 95% CI: 1.65-2.48). To improve ESRD patient outcomes, healthcare professionals need to assess the frailty of older ESRD patients, particularly by considering gender and comorbidities. Comprehensive frailty screening tools for ESRD patients on hemodialysis need to be developed.

RESUMO

Both intradialytic and out-of-clinic exercise programs (EP) have been proven to be a safe and effective way to increase fitness levels in end-stage chronic kidney disease (CKD) patients. The actual COVID-19 pandemic situation has forced the suspension of EP offered in hemodialysis centers in many countries; as well as all activities considered as "non-essential" (i.e., sport facilities and fitness centers). Therefore, there is a high risk that movement restrictions would promote physical inactivity and its associated diseases in CKD patients; especially those undergoing domiciliary confinement situations. Given the importance for CKD patients' overall health to maintain exercise levels and reach physical activity recommendations, the aim of this Protocol was to design a personalized, well-structured, multicomponent physical EP that CKD patients can safely follow at home. We also aimed to provide an initial fitness evaluation tool that allows patients to adapt the EP to their fitness level. Current general exercise recommendations for people living with chronic conditions have been analyzed to develop the present home-based EP proposal.

RESUMO

[ABSTRACT]. Objective. To identify factors associated with chronic kidney disease of non-traditional causes among children in Guatemala. Methods. A cross-sectional survey was conducted. The study population was all pediatric patients with stage 5 chronic kidney disease active in FUNDANIER’s pediatric nephrology unit (N = 156). Simple random sampling led to a total of 100 participants. Data collection consisted of a questionnaire addressing individual and household characteristics, access and utilization of health care, and place of residence when the disease began. Chronic kidney disease etiology was obtained from medical records. Municipality-level secondary data were collected. Descriptive statistics were estimated. Logistic regression was used for bivariate and multivariate analysis. Results. The odds ratio (OR) for almost all variables approached 1. Notable exceptions in household characteristics were mother’s education level up to primary school (OR 2.2727) and living in an urban setting when symptoms began (OR 0.4035). Exceptions in municipal characteristics are zones with intensive small-scale agriculture (OR 3.8923) and those with intensive large-scale agriculture (OR 0.3338). P-values and confidence intervals show that the sample was not big enough to capture statistically significant associations between variables. Conclusions. Study findings suggest that factors associated with chronic kidney disease of non-traditional causes among children in Guatemala are intensive agricultural practices in their municipality of residence, and mother’s level of education. Future research in children could use case-control designs or population-based studies in agricultural communities. Public health interventions that involve kidney function screening among children are recommended.


[RESUMEN]. Objetivo. Determinar los factores asociados a la enfermedad renal crónica por causas no tradicionales en niños en Guatemala. Métodos. Se realizó una encuesta transversal. La población de estudio fue la totalidad de pacientes pediátricos con enfermedad renal crónica en fase 5 ingresados en la unidad de nefrología pediátrica de Fundanier (N = 156). Mediante el muestreo aleatorio simple se dispuso de un total de 100 participantes. La recopilación de datos consistió en un cuestionario que abordaba las características individuales y del hogar, el acceso y el uso de la atención de salud y el lugar de residencia al inicio de la enfermedad. La etiología de la enfermedad renal crónica se obtuvo a partir de los expedientes médicos y los datos secundarios se recopilaron a nivel municipal. Se calcularon las estadísticas descriptivas y se empleó el método de regresión logística para el análisis bifactorial y multifactorial. Resultados. La razón de posibilidades (OR) se aproximó a 1 en casi todas las variables. Dos excepciones destacables en lo relativo a las características domésticas fueron el nivel de escolaridad de la madre hasta la educación primaria (OR 2,2727) y el lugar de residencia en un entorno urbano en la aparición de los síntomas (OR 0,4035). Las excepciones con respecto a las características municipales fueron las zonas de agricultura intensiva a pequeña escala (OR 3,8923) y las zonas de agricultura intensiva a gran escala (OR 0,3338). Los valores P y los intervalos de confianza indican que la muestra no fue lo suficientemente amplia para recoger las asociaciones estadísticamente significativas entre variables. Conclusiones. Los resultados del estudio sugieren que los factores asociados a la enfermedad renal crónica por causas no tradicionales en niños en Guatemala son las prácticas agrícolas intensivas en el municipio de residencia y el nivel de escolaridad de la madre. Las futuras investigaciones con niños podrían incluir el diseño de casos o los estudios poblacionales en comunidades agrícolas. Se recomiendan intervenciones de salud pública que incorporen el tamizaje de la función renal en niños.


[RESUMO]. Objetivo. Identificar os fatores associados a doença renal crônica de etiologia não tradicional em crianças na Guatemala. Métodos. Foi realizado um estudo transversal em uma população que consistiu de todos os pacientes pediátricos com doença renal crônica ativa em estágio 5 atendidos na unidade de nefrologia pediátrica da Fundación para el Niño Enfermo Renal (FUNDANIER) (N = 156). O processo de amostragem aleatória simples determinou a obtenção de uma amostra com 100 participantes. Um questionário foi usado para a coleta de dados sobre as características pessoais e familiares dos participantes, acesso à assistência de saúde e utilização de serviços e local de residência ao início da doença. Informação sobre a etiologia da doença renal crônica foi obtida dos prontuários médicos. Também foram coletados dados secundários ao nível da localidade. Estatísticas descritivas foram estimadas e um modelo de regressão logística foi usado nas análises bivariada e multivariada. Resultados. As razões de chance (odds ratio, OR) de quase todas as variáveis se aproximaram de 1. As exceções nas variáveis relativas às características familiares foram escolaridade da mãe de nível fundamental (OR 2,2727) e residir em área urbana ao início dos sintomas (OR 0,4035). As exceções nas variáveis ao nível municipal foram áreas de agricultura intensiva em pequena escala (OR 3,8923) e em grande escala (OR 0,3338). Os valores de p e os intervalos de confiança indicam que o tamanho da amostra não foi grande o suficiente para detectar associações estatisticamente significativas entre as variáveis. Conclusões. O estudo demonstrou que práticas agrícolas intensivas na localidade de residência e nível de escolaridade da mãe são fatores associados a doença renal crônica de etiologia não tradicional em crianças na Guatemala. Outros estudos em crianças devem ser realizados como estudos de caso-controle ou estudos populacionais em comunidades agrícolas. Recomendam-se também intervenções de saúde pública com a avaliação preventiva da função renal em crianças.

RESUMO

The COVID-19 pandemic has resulted in major disruption to the delivery of both routine and urgent healthcare needs in many institutions across the globe. Vascular access (VA) for haemodalysis (HD) is considered the patient's lifeline and its maintenance is essential for the continuation of a life saving treatment. Prior to the COVID-19 pandemic, the provision of VA for dialysis was already constrained. Throughout the pandemic, inevitably, many patients with chronic kidney disease (CKD) have not received timely intervention for VA care. This could have a detrimental impact on dialysis patient outcomes in the near future and needs to be addressed urgently. Many societies have issued prioritisation to allow rationing based on clinical risk, mainly according to estimated urgency and need for treatment. The recommendations recently proposed by the European and American Vascular Societies in the COVID-19 pandemic era regarding the triage of various vascular operations into urgent, emergent and elective are debatable. VA creation and interventions maintain the lifeline of complex HD patients, and the indication for surgery and other interventions warrants patient-specific clinical judgement and pathways. Keeping the use of central venous catheters at a minimum, with the goal of creating the right access, in the right patient, at the right time, and for the right reasons, is mandatory. These strategies may require local modifications. Risk assessments may need specific "renal pathways" to be developed rather than applying standard surgical risk stratification. In conclusion, in order to recover from the second wave of COVID-19 and prepare for further phases, the provision of the best dialysis access, including peritoneal dialysis, will require working closely with the multidisciplinary team involved in the assessment, creation, cannulation, surveillance, maintenance, and salvage of definitive access.

RESUMO

BACKGROUND: Studies have shown increased anxiety, depression, and stress levels among different populations during the coronavirus disease 2019 (COVID-19) pandemic. However, the impact of the pandemic on the mental health of dialysis patients remains unknown. The aim of this study was to investigate the mental health of dialysis patients during the COVID-19 pandemic compared to the period preceding the pandemic. METHODS: Data originate from the ongoing multicentre observational Dutch nOcturnal and hoME dialysis Study To Improve Clinical Outcomes (DOMESTICO). Patients who filled in a health-related quality of life (HRQoL) questionnaire during the pandemic and six to three months prior were included. The mean difference in Mental Component Summary (MCS) score of the Short Form 12 (SF-12) was analysed with multilevel linear regression. A McNemar test was used to compare presence of mental health-related symptoms during and prior to the COVID-19 pandemic. RESULTS: A total of 177 patients were included. The mean MCS score prior to COVID-19 was 48.08 ± 10.15, and 49.00 ± 10.04 during the COVID-19 pandemic. The adjusted mean MCS score was 0.93 point (95% CI - 0.57 to 2.42) higher during the COVID-19 pandemic than during the period prior to the pandemic. Furthermore, no difference in the presence of the following mental health-related symptoms was found during the COVID-19 pandemic: feeling anxious, feeling sad, worrying, feeling nervous, trouble falling asleep, and trouble staying asleep. CONCLUSIONS: The mental health of dialysis patients appears to be unaffected by the COVID-19 pandemic. Dialysis patients may be better able to cope with the pandemic, since they have high resilience and are less impacted by social distancing measures. TRIAL REGISTRATION NUMBER: Netherlands Trial Register NL6519, date of registration: 22 August 2017.

RESUMO

BACKGROUND: Obesity and chronic kidney disease (CKD) are highly prevalent worldwide and result in substantial health care costs. Obesity is a predictor of incident CKD and progression to kidney failure. Whether weight loss interventions are safe and effective to impact on disease progression and clinical outcomes, such as death remains unclear. OBJECTIVES: This review aimed to evaluate the safety and efficacy of intentional weight loss interventions in overweight and obese adults with CKD; including those with end-stage kidney disease (ESKD) being treated with dialysis, kidney transplantation, or supportive care. SEARCH METHODS: We searched the Cochrane Kidney and Transplant Register of Studies up to 14 December 2020 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs of more than four weeks duration, reporting on intentional weight loss interventions, in individuals with any stage of CKD, designed to promote weight loss as one of their primary stated goals, in any health care setting. DATA COLLECTION AND ANALYSIS: Two authors independently assessed study eligibility and extracted data. We applied the Cochrane 'Risk of Bias' tool and used the GRADE process to assess the certainty of evidence. We estimated treatment effects using random-effects meta-analysis. Results were expressed as risk ratios (RR) for dichotomous outcomes together with 95% confidence intervals (CI) or mean differences (MD) or standardised mean difference (SMD) for continuous outcomes or in descriptive format when meta-analysis was not possible. MAIN RESULTS: We included 17 RCTs enrolling 988 overweight or obese adults with CKD. The weight loss interventions and comparators across studies varied. We categorised comparisons into three groups: any weight loss intervention versus usual care or control; any weight loss intervention versus dietary intervention; and surgical intervention versus non-surgical intervention. Methodological quality was varied, with many studies providing insufficient information to accurately judge the risk of bias. Death (any cause), cardiovascular events, successful kidney transplantation, nutritional status, cost effectiveness and economic analysis were not measured in any of the included studies. Across all 17 studies many clinical parameters, patient-centred outcomes, and adverse events were not measured limiting comparisons for these outcomes. In studies comparing any weight loss intervention to usual care or control, weight loss interventions may lead to weight loss or reduction in body weight post intervention (6 studies, 180 participants: MD -3.69 kg, 95% CI -5.82 to -1.57; follow-up: 5 weeks to 12 months, very low-certainty evidence). In very low certainty evidence any weight loss intervention had uncertain effects on body mass index (BMI) (4 studies, 100 participants: MD -2.18 kg/m², 95% CI -4.90 to 0.54), waist circumference (2 studies, 53 participants: MD 0.68 cm, 95% CI -7.6 to 6.24), proteinuria (4 studies, 84 participants: 0.29 g/day, 95% CI -0.76 to 0.18), systolic (4 studies, 139 participants: -3.45 mmHg, 95% CI -9.99 to 3.09) and diastolic blood pressure (4 studies, 139 participants: -2.02 mmHg, 95% CI -3.79 to 0.24). Any weight loss intervention made little or no difference to total cholesterol, high density lipoprotein cholesterol, and inflammation, but may lower low density lipoprotein cholesterol. There was little or no difference between any weight loss interventions (lifestyle or pharmacological) compared to dietary-only weight loss interventions for weight loss, BMI, waist circumference, proteinuria, and systolic blood pressure, however diastolic blood pressure was probably reduced. Furthermore, studies comparing the efficacy of different types of dietary interventions failed to find a specific dietary intervention to be superior for weight loss or a reduction in BMI. Surgical interventions probably reduced body weight (1 study, 11 participants: MD -29.50 kg, 95% CI -36.4 to -23.35), BMI (2 studies, 17 participants: MD -10.43 kg/m², 95% CI -13.58 to -7.29), and waist circumference (MD -30.00 cm, 95% CI -39.93 to -20.07) when compared to non-surgical weight loss interventions after 12 months of follow-up. Proteinuria and blood pressure were not reported. All results across all comparators should be interpreted with caution due to the small number of studies, very low quality of evidence and heterogeneity across interventions and comparators. AUTHORS' CONCLUSIONS: All types of weight loss interventions had uncertain effects on death and cardiovascular events among overweight and obese adults with CKD as no studies reported these outcome measures. Non-surgical weight loss interventions (predominately lifestyle) appear to be an effective treatment to reduce body weight, and LDL cholesterol. Surgical interventions probably reduce body weight, waist circumference, and fat mass. The current evidence is limited by the small number of included studies, as well as the significant heterogeneity and a high risk of bias in most studies.

RESUMO

A patient suffering from advanced chronic renal disease undergoes several dialysis sessions on different dates. Several clinical parameters are monitored during the different hours of any of these sessions. These parameters, together with the information provided by other parameters of analytical nature, can be very useful to determine the probability that a patient may suffer from hypotension during the session, which should be specially watched since it represents a proven factor of possible mortality. However, the analytical information is not always available to the healthcare personnel, or it is far in time, so the clinical parameters monitored during the session become key to the prevention of hypotension. This article presents an investigation to predict the appearance of hypotension during a dialysis session, using predictive models trained from a large dialysis database, which contains the clinical information of 98,015 sessions corresponding to 758 patients. The prediction model takes into account up to 22 clinical parameters measured five times during the session, as well as the gender and age of the patient. This model was trained by means of machine learning classifiers, providing a success in the prediction higher than 80%.

RESUMO

ABSTRACT: Major adverse cardiac and cerebral events (MACCE) are common complications, which prolong hospitalization and increase mortality rate in end-stage renal disease (ESRD) patients who underwent continuous ambulatory peritoneal dialysis (CAPD). Therefore, this study aimed to investigate MACCE occurrence and its potential predictive factors in those patients.In this prospective cohort study, 196 diagnosis of ESRD patients who underwent CAPD treatment in our hospital were eligible, and their clinical data (including demographic data and biochemical indexes) were documented. Besides, their MACCE occurrence was assessed within 3-year follow-up period.In patients, 1-, 2-, and 3-year MACCE occurrence rates were 5.1%, 11.7%, and 14.8%, respectively. Meanwhile, the mean duration of accumulating MACCE occurrence was 33.1 (95% confidence interval: 32.0-34.2) months. Furthermore, age, peritoneal dialysis duration (PDD), C-reactive protein (CRP), fasting blood glucose (FBG) and total cholesterol high correlated with increased accumulating MACCE occurrence, while high-density lipoprotein cholesterol (HDL-C) high correlated with decreased accumulating MACCE occurrence. Notably, by further multivariate Cox's proportional hazard regression analysis, age, PDD, CRP, serum uric acid, and FBG high were independent predictive factors for raised accumulating MACCE occurrence, while HDL-C high was an independent predictive factor for attenuated accumulating MACCE occurrence.MACCE are common; besides, age, peritoneal dialysis duration, C-reactive protein, serum uric acid, fasting blood glucose, and high-density lipoprotein cholesterol serve as potential markers for indicating MACCE in ESRD patients who underwent CAPD.

RESUMO

ABSTRACT: Chronic renal replacement therapy by either a kidney transplant (KTX) or hemodialysis (HD) predisposes patients to an increased risk for adverse outcomes of COVID-19. However, details on this interaction remain incomplete. To provide further characterization, we undertook a retrospective observational cohort analysis of the majority of the hemodialysis and renal transplant population affected by the first regional outbreak of severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV-2) in Germany. In a region of 250,000 inhabitants we identified a total of 21 cases with SARS-CoV-2 among 100 KTX and 260 HD patients, that is, 7 KTX with COVID-19, 14 HD with COVID-19, and 3 HD with asymptomatic carrier status. As a first observation, KTX recipients exhibited trends for a higher mortality (43 vs 18%) and a higher proportion of acute respiratory distress syndrome (ARDS) (57 vs 27%) when compared to their HD counterparts. As a novel finding, development of ARDS was significantly associated with the time spent on previous renal replacement therapy (RRT), defined as the composite of dialysis time and time on the transplant (non-ARDS 4.3 vs ARDS 10.6 years, P = .016). Multivariate logistic regression analysis showed an OR of 1.7 per year of RRT. The association remained robust when analysis was confined to KTX patients (5.1 vs 13.2 years, P = .002) or when correlating the time spent on a renal transplant alone (P = .038). Similarly, longer RRT correlated with death vs survival (P = .0002). In conclusion our data suggest renal replacement vintage as a novel risk factor for COVID-19-associated ARDS and death. The findings should be validated by larger cohorts.

RESUMO

Diabetic kidney disease (DKD) is the most common chronic complication of diabetes mellitus and the major cause of end stage renal disease (ESRD). Prediction, early diagnosis and evaluation of disease progression are crucial to improve the prognosis of DKD. Estimated glomerular filtration rate (GFR) and urinary albumin excretion rate (AER) are the main diagnostic biomarkers of DKD. However, the sensitivity and specificity are insufficient. In recent years, more and more attention has been paid to the value of novel biomarkers of DKD. This article reviews the clinical studies of novel biomarkers of DKD, in order to provide reference for clinical diagnosis and prognosis evaluation of DKD.
