AIMS: Serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP) levels are rarely evaluated simultaneously in the acute phase of acute heart failure (AHF). METHOD AND RESULTS: A total of 1207 AHF patients were enrolled, and 1002 patients were analysed. Blood samples were collected within 15 min of admission. Patients were divided into two groups according to the median value of the NT-proBNP/BNP ratio [low-NT-proBNP/BNP group (Group L) vs. high-NT-proBNP/BNP group (Group H)]. A multivariate logistic regression model showed that the C-reactive protein level (per 1-mg/dL increase), Controlling Nutrition Status score (per 1-point increase), and estimated glomerular filtration rate (eGFR, per 10-mL/min/1.73 m2 increase) were independently associated with Group H [odds ratio (OR) 1.049, 95% confidence interval (CI) 1.009-1.090, OR 1.219, 95% CI 1.140-1.304, and OR 1.543, 95% CI 1.401-1.698, respectively]. A Kaplan-Meier curve analysis showed that the prognosis was significantly poorer in Group H than in Group L, and a multivariate Cox regression model revealed Group H to be an independent predictor of 180-day mortality [hazard ratio (HR) 3.084, 95% CI 1.838-5.175] and HF events (HR 1.963, 95% CI 1.340-2.876). The same trend in the prognostic impact was significantly observed in the low-BNP (<810 pg/mL, n = 501), high-BNP (≥810 pg/mL, n = 501), and low-eGFR (<60 mL/min/1.73 m2, n = 765) cohorts, and tended to be observed in normal-eGFR (≥60 mL/min/1.73 m2, n = 237) cohort. CONCLUSION: A high NT-proBNP/BNP ratio was associated with a non-cardiac condition (e.g. inflammatory reaction, nutritional status, and renal dysfunction) and is independently associated with adverse outcomes in AHF.

Thrombocytopenia, anasarca, fever, reticulin myelofibrosis/renal insufficiency, and organomegaly (TAFRO) syndrome is treated using corticosteroids and/or immunosuppressive agents as first-line therapy. We report the case of a 69-year-old female with TAFRO syndrome in which the patient presented multiple organ failure and steroid resistance, which was successfully treated using plasma exchange (PE) followed by rituximab. Decisions regarding the next treatment, including PE, are urgent for patients with steroid-resistant TAFRO syndrome. Since it is considered that immunosuppressive agents may be removed by PE, the performance of PE before treatment with immunosuppressive agents might be an option for steroid-resistant TAFRO syndrome.

Ongoing myocardial damage at the acme of the sepsis status has not been sufficiently evaluated. The clinical data of 160 sepsis patients who require intensive care and 127 outpatients with chronic heart failure (HF) were compared as a retrospective cohort study. Thereafter, the sepsis patients were divided into 3 groups according to the serum heart-type fatty acid-binding protein (H-FABP) quartiles [low H-FABP = Q1 (n = 39), middle H-FABP = Q2/Q3 (n = 81), and high H-FABP = Q4 group (n = 40)]. The H-FABP level was measured within 15 min of admission. The serum H-FABP levels in the sepsis patients [26.6 (9.3-79.0) ng/ml] were significantly higher than in the choric HF patients [6.6 (4.6-9.7) ng/ml]. A Kaplan-Meier curve showed that the survival rate of the high-H-FABP group was significantly lower than that of the middle- and low-H-FABP groups. The multivariate Cox regression analysis for the 365-day mortality showed that the high-H-FABP group (hazard ratio: 6.544, 95% confidence interval [CI] 2.026-21.140; p = 0.002) was an independent predictor of the 365-day mortality. The same trend in the prognostic impact was significantly (p = 0.015) observed in the cohort that had not been suffering from the cardiac disease before admission. The serum H-FABP level was an independent predictor of the 365-day mortality in the patients who were emergently hospitalized in the intensive-care unit due to sepsis. Ongoing myocardial damage was detected in the majority of patients with sepsis, suggesting that ongoing myocardial damage might be a candidate predictor of adverse outcomes in sepsis patients.

The Fibrosis-4 (FIB4) index could indicate the liver fibrosis in patients with chronic hepatic diseases. It was calculated using the following formula: (age × aspartate aminotransferase [U/L]) / (platelet count [103/μL] × √alanine aminotransferase [U/L]). However, the clinical impact of the FIB4 index in the acute phase of acute heart failure (AHF) has not been sufficiently investigated.A total 1,468 AHF patients were analyzed. The median FIB4 index was 2.71 [1.85-4.22]. The patients were divided into three groups according to the quartiles of their FIB4 index (low-FIB4 [Q1, ≤ 1.847], middle-FIB4 [Q2/Q3, 1.848-4.216], and high-FIB4 [Q4, ≥ 4.216] groups). A Kaplan-Meier curve analysis showed that the prognosis, such as all-cause mortality and HF events within 365 days, was significantly poorer in the high-FIB4 group than in the middle-FIB4 and low-FIB4 groups. A multivariate Cox regression model identified high FIB4 index as an independent predictor of 365-day all-cause death (hazard ratio (HR): 1.660, 95% CI: 1.136-2.427) and HF events (HR: 1.505, 95% CI: 1.145-1.978). The multivariate logistic regression analysis showed that the high plasma volume status (PVS) (Q4, odds ratio [OR]: 2.099, 95% CI: 1.429-3.082), low systolic blood pressure (SBP) (< 100 mmHg, OR: 3.825, 95% CI: 2.504-5.840), and low left ventricular ejection fraction (< 40%, OR: 1.321, 95% CI: 1.002-1.741) were associated with a high FIB4 index.A high FIB4 index can predict adverse outcomes in AHF patients, which indicate that congestive liver and liver hypoperfusion occur due to low cardiac output in the acute phase of AHF.
