Introduction and objectivesChronic kidney disease (CKD) is a risk factor for the development of acute kidney injury (AKI). Recent studies have revealed numerous biomarkers eligible for AKI prediction. However, the expression and performance of AKI biomarkers in acute injury superimposed on preexisting CKD (AonC) remain elusive. The aim of this study was to evaluate whether biomarkers which robustly expressed in acute kidney injury could predict acute injury based on CKD.Materials and methodsMice were classified into cohorts: AKI, CKD, AonC and sham. The AonC model mice were subjected to renal bilateral ischemia/reperfusion (I/R) injury fourteen days after intraperitoneally administrated with 20 mg/kg aristolochic acid. Severity of acute ischemic injury was stratified by clamping the dissected bilateral renal arteries with non-traumatic microvascular clips for 20 or 35 min. The AKI mice were induced with renal bilateral I/R injury and CKD mice were crafted with 20 mg/kg aristolochic acid administrated intraperitoneally. Histology, genetic and protein expression of biomarkers were measured in three cohorts.ResultsWe found that serum creatinine dramatically increased in severe (sAonC) but not in moderate (mAonC) injury mice. Upregulation of Kidney injury molecule-1 (KIM-1) mRNA, tissue inhibitor of metalloproteinase-2 (TIMP-2), Syndecan-1 (SDC-1) mRNA and insulin-like growth factor binding protein-7 (IGFBP7) protein indicated the onset of mAonC. An increase in neutrophil gelatinase-associated lipocalin (NGAL), rhomboid-like protein 2 (RHBDL2), Syndecan-1 (SDC-1) mRNA and protein, and a decrease in IGFBP7 protein were associated with sAonC.ConclusionsOur study revealed the variational expression of AKI biomarkers in AonC kidneys, and uncovered IGFBP7 protein can be used as a sensitive biomarker to predict and differentiate AonC severity. The performance of RHBDL2 and SDC-1 in predicting severe AonC was promising, providing new biomarkers for predicting AonC.  相似文献

Chronic kidney disease is one of the main comorbidities affecting liver transplant recipients. Most of those patients have some degree of acute or chronic kidney dysfunction at the time of transplantation, moreover they can also develop de novo chronic kidney disease once transplanted. An important increase in the incidence of chronic kidney disease in the «MELD era» has been observed. This phenomenon has partially been attributed to the weight that kidney function carries for organ allocation. In addition, the generalized use of calcineurin inhibitors has also been a contributing factor. It is of the utmost importance for us to be familiar with the current methods for evaluating kidney function before and after a liver transplantation. The two main biomarkers available today for that purpose are serum creatinine and cystatin C. Several equations have been derived from those biomarkers and have been tested in that context with mixed results, due to their biologic variability and the lack of standardization in their measurement. The gold standard continues to be the direct determination of the glomerular filtration rate through different methods; however, that is only done for research purposes. It is also essential to know the current classification of acute kidney injury and chronic kidney disease in order to make early diagnosis. The present review focuses on the recognition, diagnosis, and classification of chronic kidney disease and acute kidney injury in liver transplantation recipients.  相似文献

Urinary epidermal growth factor (uEGF) is primarily produced by the kidney, and alterations of it have been associated with several kidney diseases. The aim of this review was to describe uEGF levels in presence or progression of kidney diseases. We conducted a systematic review of observational studies with uEGF determination, patients with acute kidney injury, chronic kidney disease, primary or secondary nephropathy, or renal cancer were included. Studies were searched in Medline, Google Scholar, Science Direct, and EBSCO up to August 2, 2021. Participants and measurements characteristics from which uEGF were determined as the specificity, sensitivity, and the area under the ROC curve, whenever available, were gathered. 53 studies were included, the most frequent kidney diseases studied were acute kidney injury, chronic kidney disease, and diabetic nephropathy. In most studies, uEGF levels were lower in cases than in controls. Studies showed that uEGF levels can predict presence or progression of acute kidney injury, chronic kidney disease, and nephropathy. Heterogeneity in the reported uEGF values can be attributed to the different techniques, sampling, and ways of reporting uEGF values.Although uEGF values are lower in patients with almost all kidney diseases and their progression, uEGF evaluation methods should be standardised to be used as a biomarker in clinical practice.  相似文献

The term acute tubular necrosis was thought to represent a misnomer derived from morphological studies of human necropsies and necrosis was thought to represent an unregulated passive form of cell death which was not amenable to therapeutic manipulation. Recent advances have improved our understanding of cell death in acute kidney injury. First, apoptosis results in cell loss, but does not trigger an inflammatory response. However, clumsy attempts at interfering with apoptosis (e.g. certain caspase inhibitors) may trigger necrosis and, thus, inflammation-mediated kidney injury. Second, and most revolutionary, the concept of regulated necrosis emerged. Several modalities of regulated necrosis were described, such as necroptosis, ferroptosis, pyroptosis and mitochondria permeability transition regulated necrosis. Similar to apoptosis, regulated necrosis is modulated by specific molecules that behave as therapeutic targets. Contrary to apoptosis, regulated necrosis may be extremely pro-inflammatory and, importantly for kidney transplantation, immunogenic. Furthermore, regulated necrosis may trigger synchronized necrosis, in which all cells within a given tubule die in a synchronized manner. We now review the different modalities of regulated necrosis, the evidence for a role in diverse forms of kidney injury and the new opportunities for therapeutic intervention.  相似文献

Influenza virus infection is characterized by symptoms ranging from mild congestion and body aches to severe pulmonary edema and respiratory failure. While the majority of those exposed have minor symptoms and recover with little morbidity, an estimated 500,000 people succumb to IAV-related complications each year worldwide. In these severe cases, an exaggerated inflammatory response, known as “cytokine storm”, occurs which results in damage to the respiratory epithelial barrier and development of acute respiratory distress syndrome (ARDS). Data from retrospective human studies as well as experimental animal models of influenza virus infection highlight the fine line between an excessive and an inadequate immune response, where the host response must balance viral clearance with exuberant inflammation. Current pharmacological modulators of inflammation, including corticosteroids and statins, have not been successful in improving outcomes during influenza virus infection. We have reported that the amplitude of the inflammatory response is regulated by Linear Ubiquitin Assembly Complex (LUBAC) activity and that dampening of LUBAC activity is protective during severe influenza virus infection. Therapeutic modulation of LUBAC activity may be crucial to improve outcomes during severe influenza virus infection, as it functions as a molecular rheostat of the host response. Here we review the evidence for modulating inflammation to ameliorate influenza virus infection-induced lung injury, data on current anti-inflammatory strategies, and potential new avenues to target viral inflammation and improve outcomes.  相似文献

BackgroundColistimethate sodium (CMS) treatment has increased over the last years, being acute kidney injury (AKI) its main drug-related adverse event. Therefore, this study aimed to evaluate the incidence and risk factors associated with AKI, as well as identifying the factors that determine renal function (RF) outcomes at six months after discharge.Materials and methodsThis retrospective study included adult septic patients receiving intravenous CMS for at least 48 h (January 2007–December 2014). AKI was assessed using KDIGO criteria. The glomerular filtration rate (GFR) was estimated by the 4-variable MDRD equation. Logistic and linear models were performed to evaluate the risk factors for AKI and chronic kidney disease (CKD).ResultsAmong 126 patients treated with CMS; the incidence of AKI was 48.4%. Sepsis–severe sepsis (OR 8.07, P = 0.001), sepsis–septic shock (OR 42.9, P < 0.001), and serum creatinine (SCr) at admission (OR 6.20, P = 0.009) were independent predictors.Eighty-four patients survived; the main factors for RF evolution at the 6-month follow-up was baseline eGFR (0.58, P < 0.001) and at discharge (0.34, P < 0.001). Fifty-six percent (34/61) of the patients that developed AKI survived. At six months, 32% had CKD.ConclusionsThe development of AKI in septic patients with CMS treatment was associated with sepsis severity and SCr at admission. Baseline eGFR and eGFR at discharge were and important determinant of the RF at the 6-month follow-up. These predictors may assist in clinical decision making for this patient population.  相似文献

Background and rationaleChronic kidney disease remains an important risk factor for morbidity and mortality among LT recipients, but its exact incidence and risk factors are still unclear.Material and methodsWe carried out a retrospective cohort study of consecutive adults who underwent liver transplant (January 2009–December 2018) and were followed (at least 6 months) at our institution. CKD was defined following the Kidney Disease: Improving Global Outcomes (KDIGO) 2012 Clinical Practice Guidelines. Long-term kidney function was classified into 4 groups: no CKD (eGFR, ≥60 mL/min/1.73 m2), mild CKD (eGFR, 30–59 mL/min/1.73 m2), severe CKD (eGFR, 15–29 mL/min/1.73 m2), and end-stage renal disease (ESRD).ResultsWe enrolled 410 patients followed for 53.2 ± 32.6 months. 39 had CKD at baseline, and 95 developed de novo CKD over the observation period. There were 184 (44.9%) anti-HCV positive, 47 (11.5%) HBsAg positive, and 33 (8.1%) HBV/HDV positive recipients. Recipient risk factors for baseline CKD were advanced age (P = 0.044), raised levels of serum uric acid (P < 0.0001), and insulin dependent DM (P = 0.0034). Early post-transplant AKI was common (n = 95); logistic regression analysis found that baseline serum creatinine was an independent predictor of early post-LT AKI (P = 0.0154). According to our Cox proportional hazards model, recipient risk factors for de novo CKD included aging (P < 0.0001), early post-transplant AKI (P = 0.007), and baseline serum creatinine (P = 0.0002). At the end of follow-up, there were 116 LT recipients with CKD – 109 (93.9%) and 7 (6.1%) had stage 3 and advanced CKD, respectively. Only two of them are undergoing long-term dialysis.ConclusionThe incidence of CKD was high in our cohort of LT recipients, but only a slight decline in kidney function over time was recorded. Prevention of post-transplant AKI will improve kidney function in the long run. We need more studies to analyze the function of kidneys among LT recipients over extended follow-ups and their impact on mortality.  相似文献

The excessive chase for beauty standards and the rise of muscle dysmorphia have ultimately led to an increase in androgenic–anabolic steroids (AAS) and intramuscular injections of vitamins A, D and E (ADE) abuse, which is associated with several adverse effects and has become a public health issue. This review of literature discusses kidney injury associated with the use of AAS and ADE, highlighting the mechanisms of acute and chronic renal lesion, such as direct renal toxicity, glomerular hyperfiltration and hypercalcemia. Future perspectives regarding evaluation and early diagnosis of kidney injury in these patients are also discussed.  相似文献

ObjectivesTo describe the epidemiology, clinical profile, treatments, and to determine cardiovascular and renal outcomes after two years of follow-up in a contemporary chronic kidneay disease (CKD) population in Spain. This was also analyzed among the DAPA-CKD-like population (patients who met most inclusion criteria of DAPA-CKD trial).MethodsObservational, retrospective, population-based study using BIG-PAC database. The CKD population was defined as patients ≥18 years, with at least one diagnostic code of CKD prior to the index date (January 1st, 2018). CKD was defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 (CKD-EPI), or albuminuria >30 mg/g.ResultsWe identified 56,435 CKD patients after exclusions (76.4 years, 52.2% men, urine albumin-to-creatinine ratio 390.8 mg/g, eGFR 49.7 mL/min/1.73 m2). CKD prevalence was 4.91% and incidence 2.10 per 1000 patient-years. Regarding treatments, 69.2% were taking renin-angiotensin system inhibitors (only 4.2% at maximal doses) and 3.5% of diabetic patients SGLT-2 inhibitors. During the two years of follow-up, rates of heart failure, all-cause death, myocardial infarction, stroke, and CKD were 17.9, 12.1, 7.2, 6.3, and 5.9 events per 100 patient-years, respectively. During this period, 44% of patients were hospitalized, and 6.8% died during hospitalization. Cardiovascular outcomes were more common in the DAPA-CKD-like population.ConclusionsIn Spain, CKD population is older and comorbidities, including diabetes and heart failure, are common. Cardiovascular and renal outcomes are frequent. There is room for improvement in CKD management, particularly through the use of drugs with proven cardiovascular and renal benefit.  相似文献

Introduction and aimsObesity is a risk factor for incident chronic kidney disease (CKD). C1q/TNF related protein 3 (CTRP3) is an adipokine with multiple effects and may modulate the association between obesity and vascular diseases. The aim of the study is to explore potential links between obesity, CTRP3 levels and CKD progression.MethodsPatients with stage 3 and 4 CKD without previous cardiovascular events were enrolled and divided into groups according to body mass index (BMI) and sex. Demographic, clinical, analytical data and CTRP3 levels were collected at baseline. During follow-up, renal events (defined as dialysis initiation, serum creatinine doubling or a 50% decrease in estimated glomerular filtration rate were registered).Results81 patients were enrolled. 27 were obese and 54 non-obese. Baseline CTRP3 was similar between both groups (90.1 ± 23.8 vs 84.5 ± 6.2; p = 0.28). Of the sum, 54 were men and 27 women, with higher CTRP3 in women (81.4 ± 24.7 vs 106 ± 24.7; p < 0.01). During a mean follow-up of 68 months, 15 patients had a renal event. Patients in the higher CTRP3 tertile had less events but without statistical significance (p = 0.07). Obese patients in the higher CTRP3 tertile significantly had less renal events (p = 0.049). By multiple regression analysis CTRP3 levels could not predict renal events (HR 0.98; CI95% 0.96–1.06).ConclusionsCTRP3 levels are higher in woman than men in patients with CKD, with similar levels between obese and non obese. Higher CTRP3 levels at baseline were associated with better renal outcomes in obese patients.  相似文献

Pica is an individual entity in the patient with chronic kidney disease (CKD), which phenomenon has not been widely studied despite the high reported prevalence. Moreover, pica complications (anemia, altered electrolytes, poor absorption of micro and macronutrients and malnutrition) could be exacerbated in CKD and limit the quality of renal replacement therapy.The intake of non-caloric and non-nutritional substances could be harmful and cause effects on satiety and metabolic / electrolyte imbalance and modify the biocompatibility of micronutrients, toxins and pathogens worsening health status.In daily practice, pica could be under-reported because patient's shame to recognize it, or fear that such behavior influences their treatment. Additionally, clinicians who not investigate the presence of pica or its complications contribute to the lack of information about the magnitude and relevance of this problem in CKD.  相似文献

Objectives

To estimate early mortality in patients with chronic kidney disease who started emergency haemodialysis between 2012 and 2014 in a national referral hospital in Lima, Peru, and to identify risk factors.

Design, characteristics, participants and measurements

A retrospective cohort study was conducted by reviewing the medical records of all patients admitted to the hospital's Haemodialysis Unit from 2012 to 2014. Early mortality, defined as death within the first 90 days of starting haemodialysis, as well as age, gender, chronic kidney disease aetiology, comorbidities, cause of death, estimated glomerular filtration rate, vascular access and other variables were evaluated in patients who initiated emergency haemodialysis. Early mortality was estimated using frequencies and risk factors were determined by Poisson regression with robust variance.

Results

43.4% of patients were female, 51.5% were aged ≥ 65 years and the early mortality rate was 9.3%. The main risk factors were estimated glomerular filtration rate > 10 ml/min/1.73 m2 (RR: 2.72 [95% CI: 1.60-4.61]); age ≥ 65 years (RR: 2.51 [95% CI: 1.41-4.48]); central venous catheter infection, RR: 2.25 (95% CI: 1.08-4.67); female gender, RR: 2.15 (95% CI: 1.29-3.58); and albumin < 3.5 g/dl (RR: 1.97 [95% CI: 1.01-3.82]).

Conclusions

Early mortality was 9.3%. The main risk factor was starting haemodialysis with an estimated glomerular filtration rate > 10 ml/min/1.73 m2.  相似文献

IntroductionPatients with advanced chronic kidney disease (CKD) are at greatest risk of hyperkalemia (HK). The relationship between HK and negative outcomes (mortality or progression of renal insufficiency) in non-dialysis dependent CKD patients is controversial.AimsTo determine the incidence, prevalence, and factors related with HK in a cohort of CKD patients, and its relationship with mortality, hospitalization rate, CKD progression, and dialysis initiation.Material and methodsA retrospective, observational study in an incident cohort of adult patients with stage 4 or 5 CKD not on dialysis. Inclusion criteria were: having at least three consecutive estimated glomerular filtration rate (eGFR) measurements in a follow-up period >3 months. Decline in renal function was estimated as the slope of the individual linear regression line of eGFR over follow-up time. HK was defined as serum K levels ≥5.5 meq/l. Associations of HK with outcomes were adjusted for major confounding variables in the multivariate analysis.ResultsThe study group consisted of 1079 patients (574 males, mean age: 65±14 years) with mean baseline eGFR 14.8±4.5 ml/min/1,73 m2. Mean follow-up time was 15 months with a median of 7 serum sample determinations per patient. HK was observed at baseline in 26% of patients; in at least one serum sample during the individual follow-up period in 68%; or chronically (>50% of samples) in 33% of patients. By multivariate logistic regression, the best determinants of chronic HK were: male sex (OR = 1.529; 95% CI [1.154-2.025], p = .003), serum bicarbonate (OR = 0.863 [0.829-0.900], p <.0001), diuretic treatment (OR = 0.743 [0.556-0.992], p = .044), and angiotensin converting enzyme inhibitor and/or angiotensin receptor blockers (OR = 4.412 [2.915-6.678], p <.0001). Patients whose serum K levels were in the upper quartile showed a significantly faster CKD progression (?4.05±5.22 vs. ?2.69±5.61 ml/min/1.73 m2/year, p <.0001), and more frequent dialysis initiation (63% vs. 57%, p = .115), though lower mortality (9% vs. 17%, p = .003) and hospitalization rates (2.68±5.94 vs. 3.16±6.77 days per year, p = .301) than the other study patients. However, in the multivariate analysis, average serum K levels were not independently associated with the clinical outcomes investigated.ConclusionHK is a common biochemical finding in non-dialysis dependent CKD patients, mainly associated with prescribed medication. However, HK was not independently associated with major negative clinical outcomes.  相似文献

IntroductionThe incidence of acute kidney injury (AKI) in coronavirus disease 2019 (COVID-19) patients ranges from 0.5% to 35% and has been associated with worse prognosis. The purpose of this study was to evaluate the incidence, severity, duration, risk factors and prognosis of AKI in hospitalized patients with COVID-19.MethodsWe conducted a retrospective single-center analysis of 192 hospitalized COVID-19 patients from March to May of 2020. AKI was diagnosed using the Kidney Disease Improving Global Outcome (KDIGO) classification based on serum creatinine (SCr) criteria. Persistent and transient AKI were defined according to the Acute Disease Quality Initiative (ADQI) workgroup definitions.ResultsIn this cohort of COVID-19 patients, 55.2% developed AKI (n = 106). The majority of AKI patients had persistent AKI (n = 64, 60.4%). Overall, in-hospital mortality was 18.2% (n = 35) and was higher in AKI patients (28.3% vs. 5.9%, p < 0.001, unadjusted OR 6.03 (2.22–16.37), p < 0.001). In this multivariate analysis, older age (adjusted OR 1.07 (95% CI 1.02–1.11), p = 0.004), lower Hb level (adjusted OR 0.78 (95% CI 0.60–0.98), p = 0.035), duration of AKI (adjusted OR 7.34 for persistent AKI (95% CI 2.37–22.72), p = 0.001) and severity of AKI (adjusted OR 2.65 per increase in KDIGO stage (95% CI 1.32–5.33), p = 0.006) were independent predictors of mortality.ConclusionAKI was frequent in hospitalized patients with COVID-19. Persistent AKI and higher severity of AKI were independent predictors of in-hospital mortality.  相似文献

Background

Hyperkalaemia is a significant electrolyte imbalance in chronic kidney disease (CKD). Renin-angiotensin-aldosterone system inhibitors (RAASi) have beneficial cardio-renal properties, although they can often cause hyperkalaemia.

Objective

To examine the prevalence of hyperkalaemia in CKD, identify factors associated with its appearance and the relationship between hyperkalaemia and mortality.

Patients and methods

Retrospective observational study on patients with CKD in the period 1971-2017. The population was categorised into 3 groups: Group 1, patients with CKD without renal replacement therapy; Group 2, patients on haemodialysis; and Group 3, patients on continuous ambulatory peritoneal dialysis.

Results

A total of 2,629 patients were evaluated. The prevalence observed in the different groups was: 9.6%, 16.4% and 10.6%, respectively. Risk factors related to the appearance of hyperkalaemia in the CKD group were glomerular filtration rate (GFR) (P<.001), plasma creatinine (P<.001), plasma sodium (P<.001), haemoglobin (P=.028), diastolic blood pressure (P=.012), intake of ACE inhibitors and/or angiotensin ii receptor blockers (P=.008), treatment with metformin (P<.001) and diabetes (P=.045). Treatment with RAASi significantly increased hyperkalaemia as GFR decreased, as well as in patients with diabetes or heart failure.

Conclusions

Hyperkalaemia is a frequent metabolic alteration in CKD patients that increases in the presence of drugs with beneficial cardio-renal properties (RAASi), which means that patients often lose the benefit associated with these drugs. New, recently-appearing non-absorbable compounds, which bind to potassium in the gastrointestinal tract, enhancing faecal excretion and thus maintaining the cardio-renal benefit of the RAASi, could be relevant in the progress of patients with CKD.  相似文献

Objectives

We aimed to characterize the clinical, functional and inflammatory features of patients diagnosed diagnosed with ACO according to a new algorithm and to compare them with those of other chronic obstructive airway disease (COAD) categories (asthma and COPD).

Methods

ACO was diagnosed in a cohort of COAD patients in those patients with COPD who were either diagnosed with current asthma or showed significant blood eosinophilia (≥300 cells/μl) and/or a very positive bronchodilator response (>400 ml and >15% in FEV1).

Results

Eighty-seven (29.8%) out of 292 patients fulfilled the ACO diagnostic criteria (12.8% asthmatics who smoked <20 pack-years, 100% of asthmatics who smoked ≥20 pack-years, 47.7% of COPD with >200 eosinophils/μl in blood and none with non-eosinophilic COPD). ACO, asthma and COPD patients showed no differences in symptoms or exacerbation rate. Mean pre-bronchodilator FEV1 in ACO and asthma were similar (1741 vs 1771 ml), higher than in COPD (1431 ml, p < 0.05). DLCO was lower in ACO than in asthma (68.1 vs 84.1%) and similar to COPD (64.5%). Mean blood eosinophil count was similar in ACO and asthma (360 vs 305 cells/μl) and higher than in COPD (170 cells/μl). Periostin levels were similar in ACO to COPD (36.6 and 36.5 IU/ml) and lower than in asthma (41.5 IU/ml, p < 0.05), whereas FeNO levels in ACO were intermediate.

Conclusion

This algorithm classifies as ACO all smoking asthmatics with non-fully reversible airway obstruction and a considerable proportion of e-COPD patients, highlighting those who can benefit from inhaled corticosteroids.  相似文献

Patients with the dual burden of chronic kidney disease (CKD) and cardiovascular disease (CVD) experience unacceptably high rates of morbidity and mortality, which also entail unfavorable effects on healthcare systems. Currently, concerted efforts to identify, prevent and treat CVD in CKD patients are lacking at the institutional level, with emphasis still being placed on individual specialty views on this topic. The authors of this position paper endorse the need for a dedicated interdisciplinary team of subspecialists in cardio-nephrology that manages appropriate clinical interventions across the inpatient and outpatient settings. There is a critical need for training programs, guidelines and best clinical practice models, and research funding from nephrology, cardiology and other professional societies, to support the development of the subspecialty of cardio-nephrology. This position paper from the coordinating committee from the Working Group for Cardiorenal Medicine of the Spanish Society of Nephrology (S.E.N.) is intended to be the starting point to develop the subspecialty of cardio-nephrology within the S.E.N.. The implementation of the subspecialty in day-to-day nephrological practice will help to diagnose, treat, and prevent CVD in CKD patients in a precise, clinically effective, and health cost-favorable manner.  相似文献

Introduction

Left ventricular diastolic dysfunction (LVDD) is an independent predictor of mortality in Chronic Kidney Disease (CKD). The increase in the E/e’ ratio is an indicator of LVDD. The association between cardiovascular risk factors (CVRFs) and E/e’ in children with automated peritoneal dialysis (APD) has not been widely studied.

Objective

To measure the association between CVRFs and E/e’ in children with CKD on APD.

Methods

Cross-sectional, prolective, observational, analytical study of children aged 6–16 years on APD. We recorded age, gender, time since onset, time on dialysis, and measured weight, height, blood pressure, hemoglobin, albumin, calcium, phosphorus, parathyroid hormone, and C-reactive protein. E/e’ ratio was measured and considered to have increased when it was higher than 15.

Results

Twenty-nine children were studied, (19 females). Age was 14.0 ± 2.5 years, and 16.9 ± 11.2 months with substitutive therapy. One patient had reduced left ventricular ejection fraction, and 21 (72.4%) had increased E/e’. E/e’ correlated significantly with hemoglobin (r = –0.53, P = .003). Hemoglobin and albumin were significantly lower (9.72 ± 1.9 vs. 12.2 ± 1.8; P = .004 and 3.6 ± 0.5 vs. 4.0 ± 0.3; P = .035) and the proportion of patients with anemia and hypoalbuminemia was significantly higher (85.7% vs. 37.5%; P = .019 and 61.9% vs. 12.5%; P = .035) in patients with increased E/e’. Hemoglobin was the only independent predictor of E/e’ (β = –0.66; P = .020) and patients with anemia were 10 times more likely to have increased E/e’ (95% CI 1.5-65.6, P = .016).

Conclusions

75% of the children had increased E/e’. Anemia and hypoalbuminemia were significantly related with an increased E/e’.  相似文献

IntroductionHyponatremia is one of the most common electrolyte abnormalities in clinical practice. Data regarding factors that have impact on mortality of severe hyponatremia and outcomes of its therapeutic management is insufficient. The present study aimed to examine the factors associated with mortality and the outcomes of treatment in patients with severe hyponatremia.Materials and methodsPatients with serum Na ≤ 115 mequiv./L who were admitted to Ordu State Hospital and Ordu University Training and Research Hospital between 2014 and 2018 were included in the study. Demographic and laboratory features, severity of the symptoms, comorbid diseases, medications, and clinical outcome measures of the patients were obtained retrospectively from their medical records. Factors associated with in-hospital mortality, overcorrection and undercorrection were assessed.ResultsA total of 145 patients (median age 69 years and 58.6% female) met inclusion criteria. Diuretic use was the most common etiologic factor for severe hyponatremia that present in 50 (34.5%) patients. Sixty-seven (46.2%) patients had moderately severe while 8 patients (5.5%) had severe symptoms. The median increase in serum Na 24 h after admission in the study population was 8.9 mequiv./L (?6 to 19). Nonoptimal correction was seen in 92 (63.4%) patients. Hypertonic saline use was associated with overcorrection (OR, 3.07; 95% CI: 1.47–6.39; p = 0.002). Avoidance of hypertonic saline (aOR, 2.52; 95% CI: 1.12–5.66; p = 0.029) and having neuropsychiatric disorder (aOR, 2.60; 95% CI: 1.10–6.11; p = 0.025) were associated with undercorrection. In-hospital mortality rate was 12.4% and having CKD and cancer, undercorrection of sodium and presence of severe symptoms were significantly associated with in-hospital mortality.ConclusionSevere hyponatremia in hospitalized patients is associated with substantial mortality. The incidence of non-optimal correction of serum Na is high; under-correction, presence of severe symptoms, chronic kidney disease and cancer were the factors that increase mortality rate.  相似文献
