Abstract
OPC-61815 is an intravenous formulation vasopressin antagonist designed to treat heart failure patients, especially who have difficulty in oral intake. Tolvaptan together with DM-4103 and DM-4107 are considered as the major metabolites of OPC-61815 biotransformed in the liver via cytochrome P450 (CYP) 3A. An efficient and robust ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for quantification of OPC-61815 and its three metabolites in human plasma was developed and fully validated. To our best knowledge, it was the first published method that simultaneously quantified all of these four analytes in only one run. Simple and rapid sample preparation procedure and very short UPLC-MS/MS run time (3.5 min) offered OPC-61815 and its metabolites relatively high throughput detection, which was greatly beneficial to further clinical bio-sample analysis. The method showed good linearity and sufficient sensitivity in the range of 2.00-1000 ng/mL with a low limit of quantitation (2.00 ng/mL) for each analyte. For samples with concentrations above 1000 ng/mL, 100-fold dilution with blank plasma before sample preparation was accepted. High precision and accuracy, high selectivity and satisfactory recovery of this method were demonstrated. For all of the four analytes, no significant matrix effect or carry-over was observed. The stability of analytes and internal standards under different conditions were evaluated to ensure they were stable during the whole period of storage, preparation and detection. Also, re-injection reproducibility was investigated. In addition, the conversion test showed that almost no OPC-61815 converted into DM-4103 and DM-4107 during sample processing, while attention should be paid to the concentration difference between OPC-61815 and tolvaptan in bioanalysis. The developed UPLC-MS/MS method was successfully applied to an open, single and multiple dose administration phase I trial for monitoring the pharmacokinetics of OPC-61815. This work provided a promising way for further pharmacokinetic study of OPC-61815.

Abstract
Late kidney injury (LKI) in patients with acute heart failure (AHF) requiring intensive care is poorly understood.We analyzed 821 patients with AHF who required intensive care. We defined LKI based on the ratio of the creatinine level 1 year after admission for AHF to the baseline creatinine level. The patients were categorized into 4 groups based on this ratio: no-LKI (< 1.5, n = 509), Class R (risk; ≥ 1.5, n = 214), Class I (injury; ≥ 2.0, n = 78), and Class F (failure; ≥ 3.0, n = 20). Median follow-up after admission for AHF was 385 (346-426) days. Multivariate logistic regression analysis revealed that acute kidney injury (AKI) during hospitalization (Class R, odds ratio [OR]: 1.710, 95% confidence interval [CI]: 1.138-2.571, P = 0.010; Class I, OR: 6.744, 95% CI: 3.739-12.163, P < 0.001; and Class F, OR: 9.259, 95% CI: 4.078-18.400, P < 0.001) was independently associated with LKI. Multivariate Cox regression analysis showed that LKI was an independent predictor of 3-year all-cause death after final follow-up (hazard ratio: 1.545, 95% CI: 1.099-2.172, P = 0.012). The rate of all-cause death was significantly lower in the no-AKI/no-LKI group than in the no-AKI/LKI group (P = 0.048) and in the AKI/no-LKI group than in the AKI/LKI group (P = 0.017).The incidence of LKI was influenced by the presence of AKI during hospitalization, and was associated with poor outcomes within 3 years of final follow-up. In the absence of LKI, AKI during hospitalization for AHF was not associated with a poor outcome.

Abstract
BACKGROUND Cardiogenic shock (CS) is caused by primary cardiac dysfunction and induced by various and heterogeneous diseases (e.g., acute impairment of cardiac performance, or acute or chronic impairment of cardiac performance). MAIN BODY Although a low cardiac index is a common finding in patients with CS, the ventricular preload, pulmonary capillary wedge pressure, central venous pressure, and systemic vascular resistance might vary between patients. Organ dysfunction has traditionally been attributed to the hypoperfusion of the organ due to either progressive impairment of the cardiac output or intravascular volume depletion secondary to CS. However, research attention has recently shifted from this cardiac output ("forward failure") to venous congestion ("backward failure") as the most important hemodynamic determinant. Both hypoperfusion and/or venous congestion by CS could lead to injury, impairment, and failure of target organs (i.e., heart, lungs, kidney, liver, intestines, brain); these effects are associated with an increased mortality rate. Treatment strategies for the prevention, reduction, and reversal of organ injury are warranted to improve morbidity in these patients. The present review summarizes recent data regarding organ dysfunction, injury, and failure. CONCLUSIONS Early identification and treatment of organ dysfunction, along with hemodynamic stabilization, are key components of the management of patients with CS.

Abstract
BACKGROUND Early decongestion with diuretics could improve clinical outcomes. This study aimed to examine the impact of the time-to-target rate of urine volume (T2TUV) concept on the outcome of acute decompensated heart failure (ADHF). METHODS This multicenter retrospective study included 1670 patients with ADHF who received diuretics within 24 h of admission. T2TUV was defined as the time from admission to the rate of urine volume of 100 ml/h. The primary outcomes were in-hospital death, mortality, and re-hospitalization for 1 year. RESULTS A total of 789 patients met the inclusion criteria (T2TUV on day 1, n = 248; day 2-3, n = 172; no target rate UV, n = 369). In-hospital mortality in the day 1 group was significantly lower (2.7% vs. 5.9% vs. 11.1%; p < 0.001) than that of other groups. The mortality and re-hospitalization for 1 year in the day 1 group was significantly lower (event-free rate: 67.7% vs. 54.1% vs. 56.9%; log-lank p = 0.004) than that of other groups. In multivariate analysis, predictors of T2TUV at day 1 were age (odds ratio [OR]: 1.02, 95% confidence interval [CI]: 1.01-1.04, p = 0.007), previous hospitalized heart failure (OR: 1.47, 95% CI: [1.03-2.12], p = 0.03), N-terminal-pro B type natriuretic peptide per 1000 pg/ml (OR: 1.02, 95% CI: 1.01-1.04, p = 0.007), carperitide (OR: 0.69, 95% CI: 0.48-0.99, p = 0.05), and early administration of tolvaptan (OR: 0.6, 95% CI: 0.42-0.85, p = 0.004). CONCLUSIONS T2TUV of less than day 1 was associated with lower in-hospital mortality and decreased mortality and re-hospitalization at 1 year.

Abstract
Tolvaptan sodium phosphate (Samtas®; Otsuka Pharmaceutical, Tokyo, Japan) is a newly available intravenous aquaretic diuretic (commercially available from May 2022), which acts as an arginine vasopressin V2 receptor antagonist. Thus far, optimal patient selection as well as safety and efficacy in real-world practice remain unknown. We experienced two patients with congestive heart failure treated with tolvaptan sodium phosphate. In one patient with right-sided heart failure, oral tolvaptan was converted to intravenous tolvaptan sodium phosphate, and another one with right and left-sided heart failure and impaired swallowing function received intravenous tolvaptan sodium phosphate on a de novo basis. Following the initiation of tolvaptan sodium phosphate, their congestive symptoms ameliorated immediately without any complications. Tolvaptan sodium phosphate may be safe and effective in real-world practice, although further studies are warranted to establish optimal patient selection and clinical management. Learning objective We report here an initial experience of newly-introduced intravenous tolvaptan sodium phosphate in real-world practice. The novel medication might be particularly suitable for those with severe thirst, congestive gut edema, or requiring rapid amelioration of systemic/pulmonary congestion, although further accumulating experiences are warranted to establish optimal therapeutic strategy.

Abstract
AIMS This multicentre, randomized, controlled, double-blind, parallel-group Phase III study was conducted to confirm the non-inferiority of OPC-61815 (tolvaptan sodium phosphate) intravenous injections to oral tolvaptan tablets in patients with congestive heart failure and volume overload despite receiving diuretics other than vasopressin antagonists. METHODS AND RESULTS Congestive heart failure patients with volume overload despite receiving diuretics other than vasopressin antagonists were randomly assigned (1:1) to receive OPC-61815 (16-mg injection; n = 149) or oral tolvaptan (15-mg tablet; n = 145) once daily for 5 days. Most patients were male; the mean age and weight were 74.7 years and 62.1 kg, respectively; other demographic and clinical characteristics were similar between groups. In this study, the primary endpoint was the change in body weight from baseline to the day after the last dose. Secondary endpoints included improvement from baseline in congestive findings and New York Heart Association classification. The change in body weight was -1.67 kg [95% confidence interval (CI): -1.93, -1.41] and -1.36 kg (95% CI: -1.62, -1.10) in the OPC-61815 group and tolvaptan group, respectively; the difference in the least squares mean between the groups was -0.31 kg (95% CI: -0.68, 0.06). Given the upper CI did not exceed the pre-specified limit of 0.48, this confirmed the non-inferiority of injectable OPC-61815 to oral tolvaptan. Daily urine volume and daily fluid intake increased, and daily fluid balance was negative throughout the treatment period; changes were similar for both groups. All evaluated congestive symptoms and New York Heart Association classifications showed improvement and safety findings were similar between the groups. The incidence of hyperkalaemia was higher in the OPC-61815 group, and the incidence of thirst and dry mouth was higher in the tolvaptan group. Most treatment-emergent adverse events were mild to moderate; one serious treatment-emergent adverse event of hyperkalaemia in the OPC-61815 group was considered treatment related. CONCLUSIONS OPC-61815 (16-mg injection) was confirmed as non-inferior to oral tolvaptan (15-mg tablet) in patients with congestive heart failure and inadequate response to diuretics; no new safety concerns were observed.
