RESUMO

Cardiovascular-kidney-metabolic (CKM) syndrome is a novel construct recently defined by the American Heart Association in response to the high prevalence of metabolic and kidney disease. Epidemiological data demonstrate higher absolute risk of both atherosclerotic cardiovascular disease (CVD) and heart failure as an individual progresses from CKM stage 0 to stage 3, but optimal strategies for risk assessment need to be refined. Absolute risk assessment with the goal to match type and intensity of interventions with predicted risk and expected treatment benefit remains the cornerstone of primary prevention. Given the growing number of therapies in our armamentarium that simultaneously address all 3 CKM axes, novel risk prediction equations are needed that incorporate predictors and outcomes relevant to the CKM context. This should also include social determinants of health, which are key upstream drivers of CVD, to more equitably estimate and address risk. This scientific statement summarizes the background, rationale, and clinical implications for the newly developed sex-specific, race-free risk equations: PREVENT (AHA Predicting Risk of CVD Events). The PREVENT equations enable 10- and 30-year risk estimates for total CVD (composite of atherosclerotic CVD and heart failure), include estimated glomerular filtration rate as a predictor, and adjust for competing risk of non-CVD death among adults 30 to 79 years of age. Additional models accommodate enhanced predictive utility with the addition of CKM factors when clinically indicated for measurement (urine albumin-to-creatinine ratio and hemoglobin A1c) or social determinants of health (social deprivation index) when available. Approaches to implement risk-based prevention using PREVENT across various settings are discussed.

RESUMO

BACKGROUND: The incidence, risks, and outcomes associated with pulmonary hypertension (P-HTN) in the kidney transplant (KTx) population are not well described. METHODS: We linked US transplant registry data with Medicare claims (2006-2016) to investigate P-HTN diagnoses among Medicare-insured KTx recipients (N = 35 512) using billing claims. Cox regression was applied to identify independent correlates and outcomes of P-HTN (adjusted hazard ratio [aHR] 95%LCLaHR95%UCL) and to examine P-HTN diagnoses as time-dependent mortality predictors. RESULTS: Overall, 8.2% of recipients had a diagnostic code for P-HTN within 2 y preceding transplant. By 3 y posttransplant, P-HTN was diagnosed in 10.310.6%11.0 of the study cohort. After adjustment, posttransplant P-HTN was more likely in KTx recipients who were older (age ≥60 versus 18-30 y a HR, 1.912.403.01) or female (aHR, 1.151.241.34), who had pretransplant P-HTN (aHR, 4.384.795.24), coronary artery disease (aHR, 1.051.151.27), valvular heart disease (aHR, 1.221.321.43), peripheral vascular disease (aHR, 1.051.181.33), chronic pulmonary disease (aHR, 1.201.311.43), obstructive sleep apnea (aHR, 1.151.281.43), longer dialysis duration, pretransplant hemodialysis (aHR, 1.171.371.59), or who underwent transplant in the more recent era (2012-2016 versus 2006-2011: aHR, 1.291.391.51). Posttransplant P-HTN was associated with >2.5-fold increased risk of mortality (aHR, 2.572.843.14) and all-cause graft failure (aHR, 2.422.642.88) within 3 y posttransplant. Outcome associations of newly diagnosed posttransplant P-HTN were similar. CONCLUSIONS: Posttransplant P-HTN is diagnosed in 1 in 10 KTx recipients and is associated with an increased risk of death and graft failure. Future research is needed to refine diagnostic, classification, and management strategies to improve outcomes in KTx recipients who develop P-HTN.

RESUMO

Acute heart failure (HF) management is a complex and often involves a delicate balance of both cardiac and renal systems. Although pharmacologic diuresis is a mainstay of the pharmacologic management of decompensated HF, ultrafiltration (UF) represents a nonpharmacologic approach in the setting of diuretic resistance. We conducted a cross-sectional analysis of the 2009 through 2014 hospitalization data from the National Inpatient Sample. The study population consisted of hospitalizations with a discharge Diagnosis Related Groups of HF who were older than 18 years of age, did not have end-stage kidney disease, acute kidney injury and had not undergone hemodialysis or hemofiltration. There were 6,174 hospitalizations which included UF among the 7,799,915 hospitalizations for HF. Hospitalizations which included UF were among patients significantly younger in age (68.1 ± 1.0 vs 73.8 ± 0.1 years), male (61.9% vs 47.7%), and with higher prevalence of co-morbid conditions including chronic kidney disease (58% vs 31%), diabetes mellitus (53% vs 42%), and higher rates of co-morbidity (Charlson comorbidity score ≥2, 92% vs 80%). All-cause mortality was significantly higher among hospitalizations which included an UF (4.68% vs 2.24%). Hospitalizations with UF had a longer mean length of stay (6.2 vs 4.3 days, p <0.01) average total charges ($42,035 vs 24,867 USD, p <0.01) as compared with those without UF. Hospitalizations with UF were associated with a greater adjusted odds of all-cause mortality (odds ratio: 3.36, [95% confidence interval 1.76,6.40]), greater than DRG-level target length of stay (odds ratio, 2.46; [95 confidence interval 1.65,3.67]), and a 72% increase in the average hospital charges. In conclusion, hospitalizations which included UF identified a subgroup of HF patients with more co-morbid conditions who are at higher risk of mortality and increased resource burden in terms of length of stay and costs. These findings also highlight that the need for UF may identify patients who are most likely to benefit from a multidisciplinary cardiorenal approach to alter the trajectory of their disease.

RESUMO

The interface between nephrology and other fields of medicine continues to expand. With the advent of novel therapies in cancer, diagnostics and therapeutics in lithology, novel devices in cardiology, advances in women's health issues, novel diagnostics and therapies in glomerular diseases, and the national priority in home-based dialysis, several subspecialties in nephrology have emerged. This article will discuss the subspecialties of onconephrology, cardionephrology, obstetric nephrology, uronephrology, glomerular disease specialization, and home-based dialysis in nephrology. We discuss the current state of each subspecialty, recommended educational content, length of training, available training opportunities, and potential career pathways for each.

RESUMO

Kidney transplantation (KT) is the optimal therapy for end-stage kidney disease (ESKD), resulting in significant improvement in survival as well as quality of life when compared with maintenance dialysis. The burden of cardiovascular disease (CVD) in ESKD is reduced after KT; however, it still remains the leading cause of premature patient and allograft loss, as well as a source of significant morbidity and healthcare costs. All major phenotypes of CVD including coronary artery disease, heart failure, valvular heart disease, arrhythmias and pulmonary hypertension are represented in the KT recipient population. Pre-existing risk factors for CVD in the KT recipient are amplified by superimposed cardio-metabolic derangements after transplantation such as the metabolic effects of immunosuppressive regimens, obesity, posttransplant diabetes, hypertension, dyslipidemia and allograft dysfunction. This review summarizes the major risk factors for CVD in KT recipients and describes the individual phenotypes of overt CVD in this population. It highlights gaps in the existing literature to emphasize the need for future studies in those areas and optimize cardiovascular outcomes after KT. Finally, it outlines the need for a joint 'cardio-nephrology' clinical care model to ensure continuity, multidisciplinary collaboration and implementation of best clinical practices toward reducing CVD after KT.

RESUMO

The field of cardiorenal medicine is vast, rapidly expanding, and complex. Conventional nephrology training programs provide the fellows with the necessary core knowledge to provide general care for patients with renal and cardiovascular diseases. However, there is a need for focused training of interested physicians to master the specialized aspects of these exceedingly common clinical scenarios and optimize the care of such patients. A cardionephrology-focused training can add value to the nephrology subspecialty and potentially increase its attractiveness for a significant subset of trainees. Herein, we provide a proposal for the framework and content of such an educational activity. Creation of an international multidisciplinary workgroup to formulate a comprehensive curriculum for a dedicated cardionephrology track would be the first step. A variety of practical aspects such as implementation methods, the identification of the required skills, and the development of educational assessment tools are discussed. While this proposal primarily focuses on the integration of the curriculum into the training of nephrology fellows, it would also be appropriate (albeit in a modified and customized format) for a wider range of trainees, including cardiology fellows.

RESUMO

OBJECTIVES: To assess the impact of end stage kidney disease (ESKD) on the outcomes of Clostridium difficile infection (CDI), including complications of infection, length of hospital stay, overall mortality, and healthcare burden. METHODS: The National Inpatient Sample (NIS) database created by the Agency of Healthcare Research and Quality (AHRQ) was used, covering the years 2009 through 2013. Manufacturer-provided sampling weights were used to produce national estimates. RESULTS: All-cause unadjusted in-hospital mortality was significantly higher for patients with CDI and ESKD than for patients without ESKD (11.6% vs. 7.7%, p<0.001). The in-hospital mortality remained higher even after adjusting for age, sex, race, and Charlson index group using multivariate logistic regression (odds ratio 1.47, confidence interval 1.41-1.53). The median length of stay was found to be longer by 2days in the ESKD group (9 vs. 7 days, p<0.001). The average cost of hospitalization for patients with CDI and ESKD was also significantly higher compared to the non-ESKD group (USD $35 588 vs. $23 505, in terms of the 2013 value of the USD, p<0.001). CONCLUSIONS: The presence of end stage kidney disease in hospitalized patients with Clostridium difficile infection is associated with higher mortality, a longer length of stay, and a higher cost of hospitalization.
