RESUMEN

The multidimensional view of disease is fundamental in the care of complex diseases such as chronic kidney disease (CKD). It is appropriate to define and unify concepts that allow the different professionals involved in care to provide a multidisciplinary approach tailored to the needs of each individual. Given the increasing incidence of CKD worldwide and the fact that the disease may progress at different rates, there is a need to establish personalized, comprehensive approaches for each patient and their families at an earlier stage. This approach goes beyond the simple control of uremic symptoms or congestion and consists of addressing not only symptomatic but also functional, social and coping problems at an early stage, facilitating decision making both in the CKD and in acute situations, potentially irreversible or interventions that do not improve life expectancy. To ensure excellence in care, it is important to assess indicators of palliative care and kidney support, such as the presence of advance and shared care planning, the inclusion of psychosocial, ethical, spiritual and bereavement care. This enables the provision of comprehensive, humanized, and high-quality care for patients and their families. Palliative and kidney care is not just about patients in the last days of life. Defining, unifying, and evaluating the concepts will allow them to be applied in a timely manner at each specific moment of the CKD trajectory.

RESUMEN

Up to 50% of patients admitted for heart failure (HF) have congestion at discharge despite diagnostic and therapeutic advances. Both persistent congestion and diuretic resistance are associated with worse prognosis. The combination of hypertonic saline and loop diuretic has shown promising results in different studies. However, it has not yet achieved a standardized use, partly because of the great heterogeneity in the concentration of sodium chloride, the dose of diuretic or the amount of sodium in the diet. Classically, the movement of water from the intracellular space due to an increase in extracellular osmolarity has been postulated as the main mechanism involved. However, chloride deficit is postulated as the main up-regulator of plasma volume changes, and its correction may be the main mechanism involved. This "chloride centric" approach to heart failure opens the door to therapeutic strategies that would include diuretics to correct hypochloremia, as well as sodium free chloride supplementation.

RESUMEN

BACKGROUND: Congestion, marked by elevated cardiac filling pressures and their repercussions, is a contributing factor to morbidity and mortality in heart failure and critical illness. Relying on traditional methods for bedside evaluation often leads to inadequate decongestion and increased hospital readmissions. Point-of-care ultrasound (POCUS), particularly multi-organ POCUS, including the Venous Excess Ultrasound (VExUS) score, offers a promising approach in this scenario. VExUS enables the quantification of systemic venous congestion, aiding in fluid overload states by assessing inferior vena cava and venous Doppler waveforms. SUMMARY: This comprehensive review delves into the latest developments in comprehending and evaluating congestion, shedding light on technical intricacies to enhance the effective application of VExUS. Recent studies emphasize the importance of evaluating signs of hemodynamic congestion before administering intravenous fluids, highlighting the concept of "fluid tolerance." Moreover, VExUS-guided decongestion significantly improves decongestion rates in acute decompensated heart failure patients with acute kidney injury. Newer studies also highlight the prognostic implications of VExUS in the general ICU cohorts not confining to cardiac surgery patients. However, performing VExUS without understanding technical pitfalls may lead to clinical errors. Technical considerations in performing VExUS include nuances related to inferior vena cava and internal jugular vein ultrasound and familiarity with Doppler principles, optimal settings, and artifacts. Additionally, local structural alterations such as those seen in liver and kidney disease impact Doppler waveforms, emphasizing the need for careful interpretation. KEY MESSAGE: Overall, VExUS presents a valuable tool for assessing congestion and guiding management, provided clinicians are familiar with its technical complexities and interpret findings judiciously.

RESUMEN

Acute kidney injury (AKI) in patients with cirrhosis is a diagnostic challenge due to multiple and sometimes overlapping possible etiologies. Many times, diagnosis cannot be made based on case history, physical examination or laboratory data, especially when the nephrologist is faced with AKI with a hemodynamic basis, such as hepatorenal syndrome. In addition, the guidelines still include generalized recommendations regarding withdrawal of diuretics and plasma volume expansion with albumin for 48 h, which may be ineffective and counterproductive and may have iatrogenic effects, such as fluid overload and acute cardiogenic pulmonary edema. For this reason, the use of new tools, such as hemodynamic point-of-care ultrasound (PoCUS), allows us to phenotype volume status more accurately and ultimately guide medical treatment in a noninvasive, rapid and individualized manner.

RESUMEN

La hiponatremia es un trastorno multifactorial definido como una disminución en la concentración plasmática de sodio. Su diagnóstico diferencial requiere una evaluación adecuada del volumen extracelular. Sin embargo, la determinación del volumen extracelular, simplemente basada en la historia clínica, las constantes vitales, el examen físico y los hallazgos de laboratorio, conducen en ocasiones a un diagnóstico erróneo por lo que el enfoque terapéutico puede ser equivocado. El empleo de ecografía a pie de cama (Point-of-Care Ultrasound [PoCUS]), mediante la combinación de ecografía pulmonar (Lung Ultrasound [LUS]), Venous Excess UltraSound (VExUS) y la ecocardioscopia (Focused Cardiac Ultrasound [FoCUS]) permiten, en combinación con el resto de los parámetros, una valoración holística mucho más precisa del estado del volumen extracelular del paciente.(AU)

RESUMEN

Hyponatremia is a multifactorial disorder defined as a decrease in plasma sodium concentration. Its differential diagnosis requires an adequate evaluation of the extracellular volume (ECV). However, ECV determination, simply based on the clinical history, vital signs, physical examination, and laboratory findings can leads to misdiagnosis and inappropriate treatment. The use of Point-of-Care Ultrasound (POCUS), through the combination of Lung Ultrasound (LUS), Venous Excess UltraSound (VExUS) and Focused Cardiac Ultrasound (FoCUS), allows a much more accurate holistic assessment of the patient's ECV status in combination with the other parameters.

RESUMEN

INTRODUCTION: This study aimed to evaluate the association between the NephroCheck® test AKIRisk® score, diuretic efficiency (DE), and the odds of worsening kidney function (WKF) within the first 72 h of admission in patients hospitalized for acute heart failure (AHF). METHODS: The study prospectively enrolled 125 patients admitted with AHF. NephroCheck® test was obtained within the first 24 h of admission. DE was defined as net fluid urine output per 40 mg of furosemide equivalents. RESULTS: The median AKIRisk® score was 0.11 (IQR 0.06-0.34), and 38 (30.4%) patients had an AKIRisk® score >0.3. The median cumulative DE at 72 h was 1,963 mL (IQR 1317-3,239 mL). At 72 h, a total of 10 (8%) patients developed an absolute increase in sCr ≥0.5 mg/dL (WKF). In a multivariable setting, there was an inverse association between the AKIRisk® score and DE within the first 72 h. In fact, the highest the AKIRisk® score (centered at 0.3), the higher the likelihood of poor DE (below the median) and WKF at 72 h (odds ratio [OR] 2.04; 95%; CI: 1.02-4.07; p = 0.043, and OR 3.31, 95% CI: 1.30-8.43; p = 0.012, respectively). CONCLUSION: In patients with AHF, a higher NephroCheck® AKIRisk® score is associated with poorer DE and a higher risk of WKF at 72 h. Further research is needed to confirm the role of urinary cell cycle arrest biomarkers in the AHF scenario.

RESUMEN

BACKGROUND: The coexistence of heart and kidney diseases, also called cardiorenal syndrome, is very common, leads to increased morbidity and mortality, and poses diagnostic and therapeutic difficulties. There is a risk-treatment paradox, such that patients with the highest risk are treated with lesser disease-modifying medical therapies. SUMMARY: In this document, different scientific societies propose a practical approach to address and optimize cardiorenal therapies and related comorbidities systematically in chronic cardiorenal disease beyond congestion. Cardiorenal programs have emerged as novel models that may assist in delivering coordinated and holistic management for these patients. KEY MESSAGES: (1) Cardiorenal disease is a ubiquitous entity in clinical practice and is associated with numerous barriers that limit medical treatment. (2) The present article focuses on the practical approaches to managing chronic cardiorenal disease beyond congestion to overcome some of these barriers and improve the treatment of this high-risk population.

RESUMEN

BACKGROUND: Limited data are available on the long-term trajectory of estimated glomerular filtration rate (eGFR) in patients with chronic heart failure. OBJECTIVES: The authors evaluated eGFR dynamics using the 2009 Chronic Kidney Disease Epidemiology Collaboration equation and its prognostic significance in a real-world cohort over a 15-year follow-up. METHODS: A prospective observational registry of ambulatory heart failure outpatients was conducted, with regular eGFR assessments at baseline and on a 3-month schedule for ≤15 years. Urgent kidney function assessments were excluded. Locally weighted error sum of squares curves were plotted for predefined subgroups. Multivariable longitudinal Cox regression analyses were conducted to assess associations with all-cause and cardiovascular death. RESULTS: A total of 2,672 patients were enrolled consecutively between August 2001 and December 2021. The average age was 66.8 ± 12.6 years, and 69.8% were men. Among 40,970 creatinine measurements, 28,634 were used for eGFR analysis, averaging 10.7 ± 8.5 per patient. Over the study period, a significant decline in eGFR was observed in the entire cohort, with a slope of -1.70 mL/min/1.73 m2 per year (95% CI: -1.75 to -1.66 mL/min/1.73 m2 per year). Older patients, those with diabetes, a preserved ejection fraction, a higher baseline eGFR, elevated hospitalization rates, and those who died during follow-up experienced more pronounced decreases in the eGFR. Moreover, the decrease in kidney function correlated independently with all-cause mortality and cardiovascular death. CONCLUSIONS: These findings highlight the sustained decline in eGFR over 15 years in patients with heart failure, with variations based on clinical characteristics, and emphasize the importance of regular eGFR monitoring in this population.

RESUMEN

Kidneys have an amazing ability to adapt to adverse situations, both acute and chronic. In the presence of injury, the kidney is able to activate mechanisms such as autoregulation or glomerular hyperfiltration to maintain the glomerular filtration rate (GFR). While these adaptive mechanisms can occur in physiological situations such as pregnancy or high protein intake, they can also occur as an early manifestation of diseases such as diabetes mellitus or as an adaptive response to nephron loss. Although over-activation of these mechanisms can lead to intraglomerular hypertension and albuminuria, other associated mechanisms related to the activation of inflammasome pathways, including endothelial and tubular damage, and the hemodynamic effects of increased activity of the renin-angiotensin-aldosterone system, among others, are recognized pathways for the development of albuminuria. While the role of albuminuria in the progression of chronic kidney disease (CKD) is well known, there is increasing evidence of its negative association with cardiovascular events. For example, the presence of albuminuria is associated with an increased likelihood of developing heart failure (HF), even in patients with normal GFR, and the role of albuminuria in atherosclerosis has recently been described. Albuminuria is associated with adverse outcomes such as mortality and HF hospitalization. On the other hand, it is increasingly known that the systemic effects of congestion are mainly preceded by increased central venous pressure and transmitted retrogradely to organs such as the liver or kidney. With regard to the latter, a new entity called congestive nephropathy is emerging, in which increased renal venous pressure can lead to albuminuria. Fortunately, the presence of albuminuria is modifiable and new treatments are now available to reverse this common risk factor in the cardiorenal interaction.

RESUMEN

INTRODUCTION: In cardiorenal syndrome type 1 (CRS1), vascular congestion is central to the pathophysiology of heart failure and thus a key target for management. The venous evaluation by ultrasound (VExUS) system could guide decongestion effectively and thereby improve outcomes. METHODS: In this randomized clinical trial, patients with CRS1 (i.e., increase in creatinine ≥0.3 mg/dL) were randomized to guide decongestion with VExUS compared to usual clinical evaluation. The primary endpoint was to assess kidney function recovery (KFR), and the key secondary endpoint was decongestion evaluated by physical examination and changes in brain natriuretic peptide (BNP) and CA-125. Exploratory endpoints included days of hospitalization and mortality. RESULTS: From March 2022 to February 2023, a total of 140 patients were randomized 1:1 (70 in the VExUS and 70 in the control group). KFR was not statistically different between groups. However, VExUS improved more than twice the odds to achieve decongestion (odds ratio [OR]: 2.6, 95% CI: 1.9-3.0, p = 0.01) and the odds to reach a decrease of BNP >30% (OR: 2.4, 95% CI: 1.3-4.1, p = 0.01). The survival at 90 days, recongestion, and CA-125 were similar between groups. CONCLUSION: In patients with CRS1, we observed that VExUS-guided decongestion did not improve the probability of KFR but improved the odds to achieve decongestion.

RESUMEN

BACKGROUND: Cardiorenal syndromes constitute a spectrum of disorders involving heart and kidney dysfunction modulated by a complex interplay of neurohormonal, inflammatory, and hemodynamic derangements. The management of such patients often poses a diagnostic and therapeutic challenge to physicians owing to gaps in understanding of pathophysiology, paucity of objective bedside diagnostic tools, and individual biases. SUMMARY: In this narrative review, we discuss the role of clinician who performed bedside ultrasound in the management of patients with cardiorenal syndromes. Novel sonographic applications such as venous excess ultrasound score (VExUS) are reviewed in addition to the lung and focused cardiac ultrasound. Further, underrecognized causes of heart failure such as high-flow arteriovenous fistula are discussed. KEY MESSAGE: Bedside ultrasound allows a comprehensive hemodynamic characterization of cardiorenal syndromes.

RESUMEN

Worsening kidney function (WKF) is common in patients with acute heart failure (AHF) syndromes. Although WKF has traditionally been associated with worse outcomes on a population level, serum creatinine concentrations vary greatly during episodes of worsening heart failure, with substantial individual heterogeneity in terms of their clinical meaning. Consequently, interpreting such changes within the appropriate clinical context is essential to unravel the pathophysiology of kidney function changes and appropriately interpret their clinical meaning. This article aims to provide a critical overview of WKF in AHF, aiming to provide physicians with some tips and tricks to appropriately interpret kidney function changes in the context of AHF.

RESUMEN

Cardio-renal syndrome is a clinical condition that has recently been well defined. In acute kidney disease, this interaction might trigger chronic processes determining the onset of cardiovascular events and the progression of chronic kidney disease. Moreover, the high mortality rate of acute kidney injury (AKI) is also linked to the fact that this condition is often complicated by dysfunctions of other organs such as lungs or heart, or is associated with septic episodes. In this context the role and the potential link between bone, heart and kidney is becoming an important topic of research. The aim of this review is to describe the cardiac alterations in the presence of AKI (cardiorenal syndrome type 3) and explore how bone can interact with heart and kidney in determining and influencing the trend of AKI in the short and long term. The main anomalies of mineral metabolism in patients with AKI will be reported, with specific reference to the alterations of fibroblast growth factor 23 and Klotho as a link between the bone-kidney-heart axis.

RESUMEN

BACKGROUND: Advances in the treatment of gynecological cancers have led to increased survival in patients with gynecological cancers. Nevertheless, patients may still experience prevalent long term consequences, including lower limb lymphedema, depression, anxiety, sexual dysfunction, malnutrition, and sarcopenia, that negatively impact their quality of life. PRIMARY OBJECTIVE: To assess the impact on self-perceived quality of life of systematic screening and early treatment of lower limb lymphedema, anxiety and depression, sexual dysfunction, and sarcopenia and malnutrition compared with standard practice. STUDY HYPOTHESIS: Systematic screening with validated questionnaires leading to early diagnosis and treatment of side effects will have a positive impact on quality of life. TRIAL DESIGN: This prospective clinical trial will randomize candidates for surgery to either standard of care or systematic screening every 2 months for 2 years. Quality of life data will be collected every 4 months. After randomization, patients in the control group will follow standard usual care. Their screening scales will not be considered. In the experimental group, positive screenings will generate an alert to the physician, and patients will be referred to the corresponding specific area (rehabilitation unit, psycho-oncology unit, sexual health unit, or nutrition unit). MAJOR INCLUSION AND XCLUSION CRITERIA: Patients aged ≥18 years with ovarian, cervical, or endometrial cancer who are candidates for surgery will be included. PRIMARY ENDPOINT: Self-reported quality of life questionnaire score. SAMPLE SIZE: 168 patients will be randomized to detect a difference of 6 points in the questionnaires. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Study completion is estimated for January 2026 and the results will be presented in May 2026. TRIAL REGISTRATION NUMBER: NCT05918770.
