Background/Aims: Pneumonia is a common type of infection in maintenance hemodialysis (MHD) patients, while the treatment and prevention progress still keep limited. N-terminal-pro-brain natriuretic peptide (NT-proBNP) is an important marker in reflecting cardiac failure which also is a risk factor for pneumonia. This study aimed to determine the possible predictive value of NT-proBNP for pneumonia in MHD patients. Methods: In this prospective study, the basic information of 276 MHD patients was collected in Fudan university Zhongshan hospital, followed up for 1 year. The primary endpoint was the first pneumonia event during follow-up. The value of NT-proBNP in patients with pneumonia and without pneumonia was analyzed, to elucidate the predictive value of the NT-proBNP in hemodialysis patients with pneumonia. Results: Two hundred and seventy-six patients were finally enrolled in this prospective study, including 170 men. The mean age was 59.7 ± 14.0 years old. The average duration of hemodialysis is 56 (30–82.8) months. Enrolled patients were followed up for 1 year. During follow-up, 38 patients got pneumonia. After adjustment for other confounding factors, age (hazard ratio [HR] 1.031, 95% CI 1.003–1.060, p = 0.028), log NT-proBNP (HR 2.512, 95% CI 1.124–5.612, p = 0.025), history of smoking (HR 6.326, 95% CI 2.505–15.974, p < 0.001), β2-microglobin (HR 1.042, 95% CI 1.007–1.079, p = 0.019), and history of cerebrovascular disease (HR 2.303, 95% CI 1.107–4.719, p = 0.026) were independent predictors of pneumonia. Receiver operating characteristic curves of log NT-proBNP to predict 1 year pneumonia cases, log NT-proBNP had an area under the curve of 0.647 (95% CI [0.564–0.729], p < 0.01). Conclusions: NT-proBNP is a predictive factor of pneumonia in hemodialysis patients.

Purpose Fluorouracil (FU) is a cornerstone of colorectal cancer treatment; however, it has clinical and subclinical influence on the heart. This study aimed to clarify the pathophysiology, risk factors, and long-term effects of FU cardiotoxicity. Patients and Methods The study prospectively accrued colorectal cancer patients (n = 106) completely resected and adjuvantly treated with FU and oxaliplatin according to the FOLFOX4 regimen (infusional FU, folinic acid, and oxaliplatin). Serial measurements were made of systolic and diastolic features of the left ventricle by radionuclide ventriculography, plasma levels of N-terminal pro-brain natriuretic peptide (NT-proBNP), lactic acid, and ECG before chemotherapy, immediately after a treatment infusion, and at follow-up 2 weeks after cessation of the intended 12 treatment courses and were further evaluated by multivariate regression analysis that included cardiovascular history and its risk factors. Results In the entire cohort, NT-proBNP significantly increased from baseline 14.5 ± 3.2 pmol/L (mean ± standard error) to 28.3 ± 5.3 pmol/L during FU therapy (P < .001). Nine patients (8.5%) with cardiotoxicity had significantly higher NT-proBNP of 55.3 ± 40.8 pmol/L compared with 25.4 ± 4.1 pmol/L in those without (P < .001). In multivariate analysis, the FU-induced rise of NT-proBNP was significantly higher in females (P < .001). Plasma lactic acid significantly increased from baseline (1.3 ± 0.1 mmol/L to 1.8 ± 0.1 mmol/L) during FU therapy (P < .001). Left ventricular ejection fraction at baseline of 0.66 ± 0.01 remained unchanged at 0.65 ± 0.01 during FU therapy and 0.66 ± 0.01 at follow-up (P = .4). Conclusion FU therapy generally induces myocardial neuroendocrine changes with increasing plasma NT-proBNP and lactic acid but without long-term dysfunction of the left ventricle. The usability of NT-proBNP as a predictive marker for FU cardiotoxicity remains to be clarified.

Abstract Natriuretic peptides are produced within the heart and released in response to increased chamber wall tension and heart failure (HF). N-Terminal prohormone Brain Natriuretic Peptide (NT-proBNP) is a specific natriuretic peptide commonly assayed in persons at risk for HF. In these individuals, NT-proBNP is associated with future disease prognosis and mortality. However, its association with mortality among healthy older adults remains unknown. Therefore, we determined the association of NT-proBNP with all-cause mortality over a median follow-up of 10 years in 3253 individuals free from HF at baseline in the Long Life Family Study, a study of families recruited for exceptional longevity. We performed cox proportional hazards analysis (coxme in R) for time-to event (mortality), adjusted for field center, familial relatedness, age, sex, education, smoking, alcohol, physical activity, BMI, diabetes, hypertension, and cancer. In addition, we performed secondary analyses among individuals (N=2457) within the normal NT-proBNP limits at baseline (&lt;125pg/ml aged &lt;75 years; &lt;450pg/ml aged ≥75 years). Overall, individuals were aged 32-110 years (median 67 years; 44% male), had mean NT-proBNP of 318.5 pg/ml (median 91.0 pg/ml) and 1066 individuals (33%) died over the follow-up period. After adjustment, each 1 SD greater baseline NT-proBNP was associated with a 1.30-times increased hazard of mortality (95% CI: 1.24-1.36; P&lt;0.0001). Results were similar in individuals with normal baseline NT-proBNP (HR: 1.21; 95% CI: 1.11-1.32; P&lt;0.0001). These results suggest that NT-proBNP is a strong and specific biomarker for mortality in older adults independent of current health status, even in those with clinically-defined normal NT-proBNP.

The Impact

Introduction: Changes in N-terminal pro brain natriuretic peptide (NT-proBNP) have been demonstrated to correlate with outcomes in patients with heart failure (HF) and reduced ejection fraction (EF). However the prognostic value of a change in NT-proBNP in patients with heart failure and preserved ejection fraction (HFPEF) is unknown. Hypothesis: To assess the impact of changes in NT-proBNP on all-cause mortality, HF hospitalization and their composite in an unselected population of patients with HFPEF. Methods: 643 outpatients (age 72+12 years; 41% females) with HFPEF (ejection fraction ≥40%) enrolled in the Swedish Heart Failure Registry between 2005 and 2012 and reporting NT-proBNP levels assessment at initial registration and at follow-up were prospectively studied. Patients were divided into 2 groups according the median value of NT-proBNP absolute change that was 0 pg/ml. Median follow-up from first measurement was 2.25 years (IQR: 1.43 to 3.81). Adjusted Cox’s regression models were performed using total mortality, HF hospitalization (with censoring at death) and their composite as outcomes. Results: After adjustments for 19 baseline variables including baseline NT-proBNP, as compared with an increase in NT-proBNP levels at 6 months (NT-proBNP change>0 pg/ml), a reduction in NT-proBNP levels (NT-proBNP change<0 pg/ml) was associated with a 45.2% reduction in risk of all-cause death (HR: 0.548; 95% CI: 0.378 to 0.796; p:0.002), a 50.1% reduction in risk of HF hospitalization (HR: 0.49; 95% CI: 0.362 to 0.689; p<0.001) and a 42.6% reduction in risk of the composite outcome (HR: 0.574; 95% CI: 0.435 to 0.758; p<0.001)(Figure). Conclusions: Reductions in NT-proBNP levels over time are independently associated with an improved prognosis in HFPEF patients. Changes in NT-proBNP could represent a surrogate outcome in phase 2 HFPEF trials.

Background: People with kidney failure treated with hemodialysis (HD) are at increased risk of stroke compared to similarly aged people with normal kidney function. One concern is that treatment of renal anemia might increase stroke risk. We studied risk factors for stroke in a prespecified secondary analysis of a randomized controlled trial of intravenous iron treatment strategies in HD. Methods: We analyzed data from the Proactive IV IrOn Therapy in HaemodiALysis Patients (PIVOTAL) trial focusing on variables associated with risk of stroke. The trial randomized 2,141 adults, who had started hemodialysis <12 months earlier and who were receiving an erythropoiesis-stimulating agent (ESA), to high-dose IV iron administered proactively or low-dose IV iron administered reactively in a 1:1 ratio. Possible stroke events were independently adjudicated. We performed analyses to identify variables associated with stroke during follow-up and assessed survival following stroke. Results: During a median 2.1 years follow-up, 69 (3.2%) patients experienced a first post randomization stroke. 57 (82.6%) were ischemic strokes and 12 (17.4%) hemorrhagic strokes. There were 34 post randomization strokes in the proactive arm and 35 in the reactive arm (hazard ratio (95% confidence interval): 0.90 (0.56, 1.44), p=0.66). In multivariable models, female gender, diabetes, history of prior stroke at baseline, higher baseline systolic blood pressure, lower serum albumin and higher C-reactive protein were independently associated with stroke events during follow up. Hemoglobin, total iron or ESA dose were not associated with risk of stroke. 58% of patients with a stroke event died during follow-up, compared to 23% without a stroke. Conclusions: In hemodialysis patients, stroke risk is broadly associated with risk factors previously described to increase cardiovascular risk in this population. Proactive intravenous iron does not increase stroke risk.

Abstract Background N-terminal pro-brain natriuretic peptide (NT-proBNP) plasma levels are increased in patients with cancer. In this paper we test whether NT-proBNP may identify patients who are going to receive a future cancer diagnosis (CD) in the short term. Methods We studied 962 patients with stable coronary artery disease and free of cancer and heart failure at baseline. NT-proBNP, galectin-3, monocyte chemoattractant protein-1, high-sensitivity C-reactive protein, high-sensitivity cardiac troponin I (hsTnI), and calcidiol (vitamin D) plasma levels were assessed. The primary outcome was new CD. Results After 5.40 (2.81-6.94) years of follow-up, 59 patients received a CD. NT-proBNP [HR 1.036 CI (1.015-1.056) per increase in 100 pg/ml; p=0.001], previous atrial fibrillation [HR 3.140 CI (1.196-8.243); p=0.020], and absence of previous heart failure [HR 0.067 CI (0.006-0.802); p=0.033] were independent predictors of a receiving a CD in first three years of follow-up. None of the variables analyzed predicted a CD beyond this time. A previous history of heart failure was present in 3.3% of patients receiving a CD in the first three years of follow-up, in 0.0% of those receiving this diagnosis beyond three years, and in 12.3% of patients not developing cancer (p=0.036). Conclusions In patients with coronary artery disease, NT-proBNP is an independent predictor of CD in the first three years of follow-up but not later, suggesting that it could be detecting subclinical undiagnosed cancers. The existence of previous heart failure does not account for these differences. New studies in large populations are needed to confirm these findings.
