Abstract
BACKGROUND Tolvaptan preserves kidney function in adults with autosomal dominant polycystic kidney disease (ADPKD) at elevated risk of rapid progression. A trial (NCT02964273) evaluated tolvaptan safety and pharmacodynamics in children (5-17 years). However, progression risk was not part of study eligibility criteria due to lack of validated criteria for risk assessment in children. As risk estimation is important to guide clinical management, baseline characteristics of the study participants were retrospectively evaluated to determine whether risk of rapid disease progression in pediatric ADPKD can be assessed and to identify parameters relevant for risk estimation. METHODS Four academic pediatric nephrologists reviewed baseline data and rated participant risk from 1 (lowest) to 5 (highest) based on clinical judgement and the literature. Three primary reviewers independently scored all cases, with each case reviewed by two primary reviewers. For cases with discordant ratings (≥ 2-point difference), the fourth reviewer provided a secondary rating blinded to the primary evaluations. Study participants with discordant ratings and/or for whom data were lacking were later discussed to clarify parameters relevant to risk estimation. RESULTS Of 90 evaluable subjects, primary reviews of 69 (77%) were concordant. The proportion considered at risk of rapid progression (final mean rating ≥ 3.5) by age group was: 15-17 years, 27/34 (79%); 12- < 15, 9/32 (28%); 4- < 12, 8/24 (33%). The panelists agreed on characteristics important for risk determination: age, kidney imaging, kidney function, blood pressure, urine protein, and genetics. CONCLUSIONS High ratings concordance and agreement among reviewers on relevant clinical characteristics support the feasibility of pediatric risk assessment.

Abstract
BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) leads to progressive renal cyst formation and loss of kidney function in most patients. Vasopressin 2 receptor antagonists (V2RA) like tolvaptan are currently the only available renoprotective agents for rapidly progressive ADPKD. However, aquaretic side effects substantially limit their tolerability and therapeutic potential. In a preliminary clinical study, the addition of hydrochlorothiazide (HCT) to tolvaptan decreased 24-h urinary volume and appeared to increase renoprotective efficacy. The HYDRO-PROTECT study will investigate the long-term effect of co-treatment with HCT on tolvaptan efficacy (rate of kidney function decline) and tolerability (aquaresis and quality of life) in patients with ADPKD. METHODS The HYDRO-PROTECT study is an investigator-initiated, multicenter, double-blind, placebo-controlled, randomized clinical trial. The study is powered to enroll 300 rapidly progressive patients with ADPKD aged ≥ 18 years, with an eGFR of > 25 mL/min/1.73 m2, and on stable treatment with the highest tolerated dose of tolvaptan in routine clinical care. Patients will be randomly assigned (1:1) to daily oral HCT 25 mg or matching placebo treatment for 156 weeks, in addition to standard care. OUTCOMES The primary study outcome is the rate of kidney function decline (expressed as eGFR slope, in mL/min/1.73 m2 per year) in HCT versus placebo-treated patients, calculated by linear mixed model analysis using all available creatinine values from week 12 until the end of treatment. Secondary outcomes include changes in quality-of-life questionnaire scores (TIPS, ADPKD-UIS, EQ-5D-5L, SF-12) and changes in 24-h urine volume. CONCLUSION The HYDRO-PROTECT study will demonstrate whether co-treatment with HCT can improve the renoprotective efficacy and tolerability of tolvaptan in patients with ADPKD.

Abstract
Tolvaptan is the first disease-modifying drug proven to slow eGFR decline in high-risk patients with ADPKD. However, barriers from the patient perspective to its use in real-life settings have not been systemically examined in a large cohort. This was a single-center, retrospective study of 523 existing or new patients with ADPKD followed at the Center for Innovative Management of PKD in Toronto, Ontario, between January 1, 2016 to December 31, 2018. All patients underwent clinical assessment including total kidney volume measurements and Mayo Clinic Imaging Class (MCIC). Those who were deemed to be at high risk were offered tolvaptan with their preference (yes or no) and reasons for their choices recorded. Overall, 315/523 (60%) patients had MCIC 1C-1E; however, only 96 (30%) of them were treated with tolvaptan at their last follow-up. Among these high-risk patients, those not treated versus treated with tolvaptan were more likely to have a higher eGFR (82 ± 26 vs. 61 ± 27 ml/min/1.73 m2), CKD stages 1-2 (79% vs. 41%), and MCIC 1C (63% vs. 31%). The most common reasons provided for not taking tolvaptan were lifestyle preference related to the aquaretic effect (51%), older age ≥ 60 (12%), and pregnancy/family planning (6%). In this real-world experience, at least 60% of patients with ADPKD considered to be at high risk for progression to ESKD by imaging were not treated with tolvaptan; most of them had early stages of CKD with well-preserved eGFR and as such, were prime targets for tolvaptan therapy to slow disease progression. Given that the most common reason for tolvaptan refusal was the concern for intolerability of the aquaretic side-effect, strategies to mitigate this may help to reduce this barrier to tolvaptan therapy.

Abstract
PURPOSE Tolvaptan, a selective vasopressin V2-receptor antagonist, is approved for the treatment of SIADH-related hyponatremia, but its use is limited. The starting dose is usually 15 mg/day, but recent clinical experience suggests a lower starting dose (<15 mg/day) to reduce the risk of sodium overcorrection. However, long-term low-dose efficacy and safety has not been explored, so far. Aim of our study is to characterize safety and efficacy of long-term SIADH treatment with low-dose Tolvaptan. METHODS We retrospectively evaluated 11 patients receiving low-dose Tolvaptan (<15 mg/day) for chronic SIADH due to neurological, idiopathic and neoplastic causes. Plasma sodium levels were measured before and 1, 3, 5, 15 and 30 days after starting Tolvaptan and then at 3-month intervals. Anamnestic and clinical data were collected. RESULTS Mean time spanned 27.3 ± 29.8 months (range 6 months-7 years). Mean plasma sodium levels were within normal range 1, 3 and 6 months after starting Tolvaptan as well as after 1, 2, 3, 5 and 7 years of therapy. Neither osmotic demyelination syndrome nor overcorrection were observed. Plasma sodium levels normalization was associated with beneficial clinical effects. Neurological patients obtained seizures disappearance, improvement in neurological picture and good recovery from rehabilitation. Neoplastic patients were able to start chemotherapy and improved their general condition. Patients did not show hypernatremia during long-term follow-up and reported mild thirst and pollakiuria. CONCLUSIONS The present study shows that long-term low-dose Tolvaptan is safe and effective in SIADH treatment. No cases of overcorrection were documented and mild side effects were reported.

Abstract
BACKGROUND AND AIMS Tolvaptan has been approved for the management of cirrhosis-related complications according to the Japanese and Chinese practice guidelines, but not the European or American practice guidelines in view of FDA warning about its hepatotoxicity. This study aimed to systematically evaluate its efficacy and safety in cirrhosis. METHODS The PubMed, EMBASE, and Cochrane library databases were searched to identify randomized controlled trials (RCTs) evaluating the efficacy and/or safety of tolvaptan in cirrhosis. Risk ratios (RRs) and weight mean differences (WMDs) were calculated. The incidence of common adverse events (AEs) was pooled. RESULTS Eight RCTs were included. Tolvaptan was significantly associated with higher rates of improvement of ascites (RR = 1.49, P < 0.001) and hyponatremia (RR = 1.80, P = 0.005) and incidence of any AEs (RR = 1.18, P = 0.003), but not serious AEs (RR = 0.86, P = 0.410). Tolvaptan was significantly associated with reductions in body weight (WMD = -1.30 kg, P < 0.001) and abdominal circumference (WMD = -1.71 cm, P < 0.001), and increases in daily urine volume (WMD = 1299.84 mL, P < 0.001) and serum sodium concentration (WMD = 2.57 mmol/L, P < 0.001). The pooled incidences of dry mouth, thirst, constipation, and pollakiuria were 16%, 24%, 6%, and 17%, respectively. CONCLUSION Short-term use of tolvaptan may be considered in cirrhotic patients with ascites who have inadequate response to conventional diuretics and those with hyponatremia.

Abstract
INTRODUCTION Furosemide, a loop diuretic, is often empirically used to treat acute decompensated heart failure (ADHF) initially. Conversely, decongestion using tolvaptan, an aquaretic, is thought to maintain renal function compared to furosemide. However, it has not been investigated in patients with advanced chronic kidney disease (CKD) at high risk of developing acute kidney injury (AKI). This study aimed to investigate AKI incidence using tolvaptan add-on treatment, compared to increased furosemide treatment for patients with ADHF complicated by advanced CKD. METHODS We retrospectively studied patients with advanced CKD (estimated glomerular filtration rate [eGFR] <45 mL/min/1.73 m2) who developed ADHF under outpatient furosemide treatment. The exposure was set to tolvaptan add-on treatment, and the control was set to increased furosemide treatment. RESULTS Of the 163 patients enrolled, 79 were in the tolvaptan group and 84 in the furosemide group. The mean age was 71.6 years, the percentage of males was 63.8%, the mean eGFR was 15.7 mL/min/1.73 m2, and patients with CKD stage G5 were 61.9%. AKI incidence was 17.7% in the tolvaptan group and 42.9% in the furosemide group (odds ratio [95% confidence interval]: 0.34 [0.13-0.86], p = 0.023 in multivariate logistic regression analysis). Persistent AKI incidence was 11.8% in the tolvaptan group and 32.9% in the furosemide group (odds ratio [95% confidence interval]: 0.34 [0.10-1.06], p = 0.066 in the multinomial logit analysis). CONCLUSION This study suggests that tolvaptan may be better than furosemide in patients with ADHF experiencing complicated advanced CKD.

Abstract
BACKGROUND/AIM We evaluated the efficacy and safety of tolvaptan for autosomal dominant polycystic kidney disease (ADPKD) in real-world practice. PATIENTS AND METHODS We retrospectively reviewed the cases of 27 patients who had been diagnosed with ADPKD between January 2014 and December 2022. Among them, 14 patients received tolvaptan (60 mg/day; morning: 45 mg, night: 15 mg) after being admitted for 2 days. In the outpatient clinic, blood and urine samples were taken monthly. RESULTS The mean age, pretreatment estimated glomerular filtration rate (eGFR), treatment duration, and total kidney volume were 60 years, 45.6 ml/min/1.73 m2, 2.8 years, and 2,390 ml, respectively. One month later, the patients' renal dysfunction had worsened slightly, and their serum sodium concentrations had significantly increased. After one year, the mean reduction in the eGFR was -5.5 ml/min/1.73 m2 Moreover, at 3 years the patients' renal function was stable. No hepatic dysfunction or electrolyte abnormalities were noted, although discontinuation occurred in two cases. Tolvaptan treatment is considered to be safe. CONCLUSION Tolvaptan was effective against ADPKD in a real-world setting. Moreover, the safety of tolvaptan was confirmed.

Abstract
BACKGROUND Tolvaptan (TLV) is a selective vasopressin receptor 2 antagonist administered for congestive heart failure (CHF) after inadequate response to other diuretics. The effectiveness and safety of TLV have been evaluated well in adult patients. However, reports on its use in pediatric patients, especially infants, are scarce. METHODS We retrospectively evaluated 41 children younger than 1 year of age who received TLV for CHF for congenital heart disease (CHD) between January 2010 and August 2021. We monitored the occurrence of adverse events, including acute kidney injury and hypernatremia, as well as laboratory data trends. RESULTS Of the 41 infants included, 51.2% were male. The median age when TLV was initiated was 2 months, interquartile range (IQR) 1-4 months, and all infants had been administered other diuretics previously. The median dose of TLV was 0.1 mg/kg/day (IQR, 0.1-0.1). Urine output increased significantly after 48 h of treatment: baseline, 315 mL/day (IQR, 243-394); 48 h, 381 mL/day (IQR, 262-518) , p = 0.0004; 72 h, 385 mL/day (IQR, 301-569), p = 0.0013; 96 h, 425 mL/day (IQR, 272-524), p = 0.0006; and 144 h, 396 mL/day (IQR, 305-477), p = 0.0036. No adverse events were observed. CONCLUSIONS Tolvaptan can be used safely and efficiently in infants with CHD. From the perspective of adverse effects, initiating administration at a lower dosage is preferable because this was found to be sufficiently effective.

Abstract
BACKGROUND Tolvaptan slows expansion of kidney volume and kidney function decline in adults with autosomal dominant polycystic kidney disease (ADPKD). Progression during childhood could be treated before irreversible kidney damage occurs, but trial data are lacking. We evaluated the safety and efficacy of tolvaptan in children/adolescents with ADPKD. METHODS This was the 1-year, randomized, double-blind, portion of a phase 3b, two-part trial being conducted at 20 academic pediatric nephrology centers. Key eligibility criteria were ADPKD and eGFR ≥60 ml/min per 1.73 m2. Participants aged 12-17 years were the target group (group 1, enrollment goal n≥60); participants aged 4-11 years could additionally enroll (group 2, anticipated enrollment approximately 40). Treatments were tolvaptan or placebo titrated by body weight and tolerability. Coprimary end points, change from baseline in spot urine osmolality and specific gravity at week 1, assessed inhibition of antidiuretic hormone activity. The key secondary end point was change in height-adjusted total kidney volume (htTKV) to month 12 in group 1. Additional end points were safety/tolerability and quality of life. Statistical comparisons were exploratory and post hoc. RESULTS Among the 91 randomized (group 1, n=66; group 2, n=25), least squares (LS) mean reduction (±SEM) in spot urine osmolality at week 1 was greater with tolvaptan (-390 [28] mOsm/kg) than placebo (-90 [29] mOsm/kg; P<0.001), as was LS mean reduction in specific gravity (-0.009 [0.001] versus -0.002 [0.001]; P<0.001). In group 1, the 12-month htTKV increase was 2.6% with tolvaptan and 5.8% with placebo (P>0.05). For tolvaptan and placebo, respectively, 65% and 16% of subjects experienced aquaretic adverse events, and 2% and 0% experienced hypernatremia. There were no elevated transaminases or drug-induced liver injuries. Four participants discontinued tolvaptan, and three discontinued placebo. Quality-of-life assessments remained stable. CONCLUSIONS Tolvaptan exhibited pharmacodynamic activity in pediatric ADPKD. Aquaretic effects were manageable, with few discontinuations. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER Safety, Pharmacokinetics, Tolerability and Efficacy of Tolvaptan in Children and Adolescents With ADPKD (Autosomal Dominant Polycystic Kidney Disease) NCT02964273.

Abstract
<b><i>Background:</i></b> Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary cause of end-stage kidney disease. Currently, tolvaptan is the only treatment that has proven to delay disease progression. The most notable side effect of this therapy is drug-induced liver injury; however, recently, there have been two reports of creatine kinase (CK) elevation in ADPKD patients on tolvaptan treatment. We set out to monitor and determine the actual incidence of CK elevation and evaluate its potential association with other clinical factors. <b><i>Methods:</i></b> This is an observational retrospective multicenter study performed in rapidly progressive ADPKD patients on tolvaptan treatment from Barcelona, Spain. Laboratory tests, demographics, treatment dose, and reported symptoms were collected from October 2018 to March 2021. <b><i>Results:</i></b> Ninety-five patients initiated tolvaptan treatment during follow-up. The medication had to be discontinued in 31 (32.6%) patients, primarily due to aquaretic effects (12.6%), elevated liver enzymes (8.4%), and symptomatic or persistently elevated CK levels (3.2%). Moreover, a total of 27 (28.4%) patients had elevated CK levels, with most of them being either transient (12.6%), mild and asymptomatic (4.2%), or resolved after dose reduction (3.2%) or temporary discontinuation (2.1%). <b><i>Conclusion:</i></b> We present the largest cohort that has monitored CK levels in a real-life setting, finding them elevated in 28.4% of patients. More research and monitoring will help us understand the clinical implications and the pathophysiological mechanism of CK elevation in this population.

Abstract
Background Autosomal dominant polycystic kidney disease (ADPKD) is a progressive condition that eventually leads to end-stage renal disease. A phase 3 trial of tolvaptan (TEMPO 3:4; NCT00428948) and its open-label extension (TEMPO Extension Japan: TEMPO-EXTJ; NCT01280721) were conducted in patients with ADPKD. In this post hoc analysis, effects on renal function and the safety profile of tolvaptan were assessed over a long-term period that included the 3-year TEMPO 3:4 and the approximately 3-year TEMPO-EXTJ trials. Methods Patients from Japanese trial sites who completed TEMPO 3:4 were offered participation in TEMPO-EXTJ. Patients whose efficacy parameters were measured at year 2 in TEMPO-EXTJ for efficacy evaluation were included. The annual slope of the estimated glomerular filtration rate (eGFR) and growth in total kidney volume (TKV) were analyzed. Results In patients who received tolvaptan in TEMPO 3:4 and TEMPO-EXTJ, the annual slope of eGFR (mL/min/1.73 m2) was − 3.480 in TEMPO 3:4 and − 3.417 in TEMPO-EXTJ, with no apparent effect of an approximately 3.6-month off-treatment interval between the two trials. In patients who received a placebo in TEMPO 3:4 before initiating tolvaptan in TEMPO-EXTJ, the slope of eGFR was significantly less steep from TEMPO 3:4 (− 4.287) to TEMPO-EXTJ (− 3.364), a difference of 0.923 (P = 0.0441). Conclusion The TEMPO-EXTJ trial supports a sustained beneficial effect of tolvaptan on eGFR. In patients who received a placebo in TEMPO 3:4, initiation of tolvaptan in TEMPO-EXTJ was associated with a significant slowing of eGFR decline.

Abstract
The purpose of this study was to determine the efficacy and safety of tolvaptan in Japanese patients with hyponatremia secondary to syndrome of inappropriate secretion of antidiuretic hormone (SIADH). This multicenter, open-label, dose-escalation, phase III study enrolled Japanese patients (20-85 years old) with hyponatremia secondary to SIADH who were unresponsive to fluid restriction. Oral tolvaptan was administered for up to 30 days, initially at 7.5 mg/day, but escalated daily as necessary, based on the serum sodium concentration and safety, over the first 10 days until the optimal maintenance dose was determined for each patient (maximum 60 mg/day). The primary endpoint was the proportion of patients with normalized serum sodium concentration on the day after the final tolvaptan dose. Secondary endpoints included the mean change in serum sodium concentration from baseline on the day after the final dose. Sixteen patients (male, 81.3%; mean ± standard deviation age 71.9 ± 6.1 years) received tolvaptan treatment and 11 patients completed the study with one patient re-administered tolvaptan in the treatment period. Serum sodium concentrations normalized in 13 of 16 (81.3%) patients on the day after the final tolvaptan dose. The mean change in serum sodium concentration from baseline on the day after the final dose was 11.0 ± 4.3 mEq/L. Adverse events considered related to tolvaptan (10 [62.5%] patients) were generally of mild to moderate severity. Oral tolvaptan corrects hyponatremia in Japanese patients with SIADH with a similar efficacy and safety profile as that noted in non-Japanese patients.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent monogenic kidney disease, alone responsible for over 10% of patients with end-stage renal disease, and with an important impact on public health. Tolvaptan (TOLV) has recently been approved in many European countries for its ability to slow disease progression in patients that are eligible for treatment. Nevertheless, the doctor's choice to prescribe the drug and the patient's compliance are strongly influenced by the aquaretic effect complications. In a cohort of patients pertaining to the Nephrology clinic of the AOU Federico II of Naples and treated with TOLV, we assessed not only the adherence to the treatment and the safety of the drug, but also the real feasibility of this therapy through specific questionnaires on sleep quality, abdominal-renal pain, quality of life and patients' general satisfaction. Within the limits of preliminary data and on the basis of the responses of our population, followed for a period of at least one year and administered the maximum titration dosage, it can be asserted that the doubts regarding the real compliance of the patients can be overcome.

Abstract
This study aimed to investigate the short-term efficacy and safety of tolvaptan as an add-on to traditional diuretics in patients with acute heart failure (AHF). The PubMed, EMBASE, Cochrane Library, and Web of Science databases were comprehensively searched for all randomized controlled trials (RCTs) that examined AHF patients treated with tolvaptan as a combination therapy with traditional diuretics published on or before December 2, 2019. Efficacy indicators such as improved dyspnea, reduced edema, and changes in urine output and body weight were evaluated. In-hospital mortality and worsening renal function (WRF) were measured as safety indicators. Data from the published literature included in this study were independently extracted by two reviewers. The Cochrane risk of bias tool was used to evaluate the quality of the included RCTs. Twelve RCTs involving 5577 patients admitted for AHF were included. Compared with traditional diuretics alone, add-on tolvaptan significantly relieved dyspnea, reduced weight, increased total urine volume and changes in urine volume from baseline, reduced edema, and increased serum sodium concentration in the short term without increasing the mortality. Most importantly, a low dose of tolvaptan (7.5-15 mg/d) significantly reduced the incidence of WRF, while a high dose (30 mg/d) had the opposite effect. Short-term add-on tolvaptan in hospitalized AHF patients could significantly relieve shortness of breath, reduce body weight, improve edema, and increase urine output and serum sodium concentrations without increasing mortality. The protective effects of add-on tolvaptan against WRF, however, were observed at low doses, but not at high doses.

Abstract
RATIONALE Tolvaptan (TLV) is a selective vasopressin type 2 receptor antagonist, which has an active effect on patients with congestive heart failure especially combined with hyponatremia. Increasingly, evidence has demonstrated that low-dose tolvaptan can dramatically relieve patients' dyspnea and the dose would not cause severe electrolyte abnormalities. Even hypernatremia is a major adverse effect of tolvaptan, treatment with tolvaptan shows good security and is well-tolerated. Few cases have reported that patients who developed severe hypernatremia induced by low-dose Tolvaptan. PATIENT CONCERNS A 68-year-old man was admitted to our hospital with dyspea and general fatigue. He was diagnosed with acute decompensated heart failure due to ischemic cardiomyopathy. In order to improve fluid retention and relieve his dyspnea, low-dose TLV (7.5 mg qd) was performed. After the 3-day treatment using TLV, we observed that he became delirious and his limbs shook uncontrollably. High serum sodium 173 mmol/L was noted compared to the results of the first examination (137 mmol/L). After intensive rescue, serum sodium was restored to normal (135 mol/L). Later, when the patient refused continuous renal replacement therapy (CRRT), we tried again to use a lower dose of TLV to improve diuretic resistance. Two days later, Serum sodium rose again (162 mmol/L). DIAGNOSES During the course of therapy, we did not strictly require the patient to control the fluid intake. No other medication could cause elevation of serum sodium. Therefore, we suspected a high sensitivity to the side effect of TLV. INTERVENTION Stop the use of TLV and encourage the patient to drink plenty of water. Gastric tube was inserted orally to increase the intake of fresh water. OUTCOMES His serum sodium decreased gradually and his psychiatric symptom recovered. During this period, Overall condition of the patient was stable. After being discharged from the hospital, the patient eventually died of cardiac arrest due to critically ill heart failure. LESSONS Hypernatremia is a severe side effect of TLV. For critical patients, TLV should be used at a low dose and electrolyte should be detected in time.

Abstract
OBJECTIVES Our objective was to explore the effects of tolvaptan as a new therapeutic approach in patients with right heart failure with tricuspid insufficiency (TI). METHODS This prospective, multicenter, non-randomized controlled pilot study enrolled patients (N = 40) with TI from the Shanghai Chest Hospital and Shanghai Tongren Hospital who fulfilled inclusion criteria between March 2015 and June 2016. Participants were assigned to receive either tolvaptan combined with torasemide (n = 20) or torasemide monotherapy (n = 20; control group). The primary endpoints were changes in patient weight and in tricuspid annular plane systolic excursion (TAPSE) after 10 days of treatment. The secondary endpoints included net fluid balance and cardiac functions before and after medication from the first to the tenth day of treatment. Safety was evaluated by monitoring adverse and serious adverse events. RESULTS TAPSE significantly increased in the tolvaptan group compared with the control group after 10 days of medication (P = 0.029). Daily weight losses in the tolvaptan group significantly increased as the time of treatment increased (time × group, P = 0.022). Recovery to New York Heart Association (NYHA) grade I occurred 4 days earlier in the tolvaptan group. In addition, the net fluid balance and median net fluid balance were significantly higher in the tolvaptan group. Eight adverse events and one serious adverse event were recorded in the tolvaptan group and 15 adverse events were recorded in the control group. CONCLUSIONS Our results indicate that tolvaptan might be a useful and safe drug to improve heart function in patients with right heart failure with TI after left heart valve replacement.

Abstract
BACKGROUND The protocol of this study will be proposed for systematic evaluation of the efficacy and safety of tolvaptan in the treatment of chronic heart failure (CHF). METHODS We will retrieve the following electronic databases for randomized controlled trials assessing the efficacy of tolvaptan in patients with CHF: PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, Scopus, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Information, and Wanfang Data. Each database will be retrieved from inception to February 1, 2019 without any limitations. The entire process of study selection, data extraction, and methodological quality evaluation will be conducted by 2 independent authors. RESULTS The protocol of this proposed study will compare the efficacy and safety of tolvaptan in the treatment of patients with CHF. The outcomes will include all-cause mortality, change in body weight, urine output, change in serum sodium; and incidence of all adverse events. CONCLUSION The findings of this proposed study will summarize the current evidence of tolvaptan for CHF. ETHICS AND DISSEMINATION All data used in this systematic review will be collected from the previous published trials. Thus, no research ethics approval is needed for this study. The findings of this study will be published at a peer-reviewed journal. PROSPERO REGISTRATION NUMBER PROSPERO CRD42019120818.

Abstract
Increased re-hospitalization due to acute decompensated heart failure (ADHF) is a modern issue in cardiology. The aim of this study was to investigate risk factors for re-hospitalization due to worsening heart failure, and the effect of tolvaptan (TLV) on decreasing the number of re-hospitalizations. This was a multicenter, retrospective study. The re-hospitalization factors for 1191 patients with ADHF were investigated; patients receiving continuous administration of TLV when they were discharged from the hospital (n = 194) were analyzed separately. Patients were classified into 5 risk groups based on their calculated Preventing Re-hospitalization with TOLvaptan (Pretol) score. The total number of patients re-hospitalized due to worsening heart failure up to one year after discharge from the hospital was 285 (23.9%). Age ≥80 years, duration since discharge from the hospital after previous heart failure <6 months, diabetes mellitus, hemoglobin <10 g/dl, uric acid >7.2 mg/dl, left ventricular ejection fraction (LVEF) <40%, left atrial volume index (LAVI) >44.7 ml/m2, loop diuretic dose ≥20 mg/day, hematocrit <31.6%, and estimated glomerular filtration rate (eGFR) <50 ml/min/1.73m2 were independent risk factors for re-hospitalization for worsening heart failure. There was a significant reduction in the re-hospitalization rate among TLV treated patients in the Risk 3 group and above. In conclusions, age, duration since previous heart failure, diabetes mellitus, hemoglobin, uric acid, LVEF, LAVI, loop diuretic dose, hematocrit, and eGFR were all independent risk factors for re-hospitalization for worsening heart failure. Long-term administration of TLV significantly decreases the rate of re-hospitalization for worsening heart failure in patients with a Pretol score of 7.

Abstract
BACKGROUND Currently, the vasopressin V2 receptor antagonist tolvaptan is the only available treatment for autosomal dominant polycystic kidney disease (ADPKD), but there are tolerability issues due to aquaretic side-effects such as polyuria. A possible strategy to ameliorate these side-effects may be addition of a thiazide diuretic, this is an established treatment in nephrogenic diabetes insipidus, a condition where vasopressin V2 receptor function is absent. CASE PRESENTATION We describe a 46-year-old male ADPKD-patient, who was prescribed tolvaptan, which caused polyuria of around 5 l per day. Hydrochlorothiazide was added to treat hypertension, which resulted in a marked decrease in urine production. While using tolvaptan, rate of eGFR decline was - 1.35 mL/min/1.73m2 per year, whereas after hydrochlorothiazide was initiated this was - 3.97 mL/minute/1.73m2 per year. CONCLUSIONS This case report indicates that while addition of hydrochlorothiazide may improve tolerability of vasopressin V2 receptor antagonists, co-prescription should only be used with great scrutiny as it may decrease tolvaptan effect on rate of ADPKD disease progression.

Abstract
BACKGROUND Tolvaptan is an orally administered selective vasopressin 2 receptor antagonist that promotes aquaresis. This study aimed to evaluate the efficacy and safety of tolvaptan on management of systemic fluid balance after cardiovascular surgery using cardiopulmonary bypass. . METHODS Sixty-four patients who underwent cardiovascular surgery using cardiopulmonary bypass in our hospital were enrolled for this prospective, randomized study. These patients were divided into three groups: tolvaptan 15 mg+furosemide 20 mg (TH group), tolvaptan 7.5 mg+furosemide 20 mg (TI group), and furosemide 40 mg+spironolactone 50 mg (C group). The endpoint was safety management of systemic fluid balance using tolvaptan without renal dysfunction and electrolyte imbalance. RESULTS The mean daily urine output in the TH and TL groups (2656±767 and 2505 ±684 mL) was significantly higher than that in the C group (1956±494 mL, TH vs C: p<0.01 and TL vs C: p=0.03). The lowest serum sodium level during medication in the TH group (139.3 ±2.3 mEq/L) was significantly higher than that in the C group (137.1±2.9 mEq/L, p=0.03) The lowest serum osmolality during medication in the TH group was significantly higher than that in the C group (284.8 ±4.3 vs 279.5± 6.3 mOsm/kg, p<0.01). None had critical hypernatremia, hyperosm6lality, or renal dysfunction in any. of the groups. CONCLUSIONS Tolvaptan exerts, a strong diuretic effect compared with conventional diuretics (furosemide and spironolactone) during the postoperative period after an operation using cardiopulmonary bypass without adverse effects on electrolyte balance and renal function.
