Abstract
OBJECTIVES To evaluate the efficacy of the simultaneous hypertonic saline solution and IV furosemide (HSS+Fx) for patients with fluid overload compared with IV furosemide alone (Fx). DATA SOURCES Electronic databases (MEDLINE, EMBASE, CENTRAL, Cochrane Database of Systematic Reviews, PsycINFO, Scopus, and WOS) were searched from inception to March 2020. STUDY SELECTION Randomized controlled trials on the use of HSS+Fx in adult patients with fluid overload versus Fx were included. DATA EXTRACTION Data were collected on all-cause mortality, hospital length of stay, heart failure-related readmission, along with inpatient weight loss, change of daily diuresis, serum creatinine, and 24-hour urine sodium excretion from prior to post intervention. Pooled analysis with random effects models yielded relative risk or mean difference with 95% CIs. DATA SYNTHESIS Eleven randomized controlled trials comprising 2,987 acute decompensated heart failure patients were included. Meta-analysis demonstrated that HSS+Fx was associated with lower all-cause mortality (relative risk, 0.55; 95% CI, 0.46-0.67; p < 0.05; I2 = 12%) and heart failure-related readmissions (relative risk, 0.50; 95% CI, 0.33-0.76; p < 0.05; I2 = 61%), shorter hospital length of stay (mean difference, -3.28 d; 95% CI, -4.14 to -2.43; p < 0.05; I2 = 93%), increased daily diuresis (mean difference, 583.87 mL; 95% CI, 504.92-662.81; p < 0.05; I2 = 76%), weight loss (mean difference, -1.76 kg; 95% CI, -2.52 to -1.00; p < 0.05; I2 = 57%), serum sodium change (mean difference, 6.89 mEq/L; 95% CI, 4.98-8.79; p < 0.05; I2 = 95%), and higher 24-hour urine sodium excretion (mean difference, 61.10 mEq; 95% CI, 51.47-70.73; p < 0.05; I2 = 95%), along with decreased serum creatinine (mean difference, -0.46 mg/dL; 95% CI, -0.51 to -0.41; p < 0.05; I2 = 89%) when compared with Fx. The Grading of Recommendation, Assessment, Development, and Evaluation certainty of evidence ranged from low to moderate. CONCLUSIONS Benefits of the HSS+Fx over Fx were observed across all examined outcomes in acute decompensated heart failure patients with fluid overload. There is at least moderate certainty that HSS+Fx is associated with a reduction in mortality in patients with acute decompensated heart failure. Factors associated with a successful HSS+Fx utilization are still unknown. Current evidence cannot be extrapolated to other than fluid overload states in acute decompensated heart failure.

European review for medical and pharmacological sciences. 2021;(14):4729-4737
Abstract
OBJECTIVE A meta-analysis was performed to evaluate the effect of furosemide combined with hydration therapy on the incidence and prognosis of contrast-induced acute kidney injury (CI-AKI) in patients after coronary intervention. MATERIALS AND METHODS Through the PubMed, EMBASE, Cochrane Library and Web of Science databases, all relevant literature from database establishment until October 1, 2020, was retrieved and screened. Quality evaluation was performed using the risk of bias evaluation tool recommended by the Cochrane Collaboration network, data extraction was performed based on pre-selected effect indicators, and statistics were calculated using Review Manager 5.3 analysis software. RESULTS A total of 2084 patients in 9 studies were included in the meta-analysis. The results showed that furosemide combined with hydrotherapy had no effect on the incidence of CI-AKI (OR = 0.85, 95% CI [0.46, 1.60], p = 0.62) and can significantly decrease the incidence of major adverse cardiovascular events (MACEs) (OR = 0.43, 95% CI [0.27, 0.67], p = 0.0003) and mortality (OR = 0.24, 95% CI [0.08, 0.79], p = 0.02) in patients. However, it had no significant impact on the need for postoperative dialysis treatment, postoperative creatinine level or length of hospital stay. CONCLUSIONS Furosemide combined with hydration therapy has no significant effect on the incidence of CI-AKI in patients after coronary intervention but can reduce the incidence of MACEs and mortality, thereby providing clinical benefits.

Abstract
Although torsemide's oral bioavailability and half-life theoretically render it a more efficient diuretic than furosemide, the clinical outcomes of torsemide compared with furosemide remain unclear. We performed a systematic review and meta-analysis, including all published studies that compared torsemide and furosemide use in heart failure patients from January 1996 through August 2019. Nineteen studies (9 randomized control trials [RCTs] and 10 observational studies) with a total of 19,280 patients were included. During a mean follow-up duration of 15 months, torsemide was associated with a numerically lower risk of hospitalization due to heart failure (10.6% vs 18.4%; odds ratio [OR] 0.72, 95% confidence interval [CI] [0.51, 1.03], p = 0.07, I2 = 18%; number needed to treat [NNT] = 23) compared with furosemide. Torsemide was associated with statistically significant more improvement in functional status from New York Heart Association (NYHA) class III/IV to I/II (72.5% vs 58%; OR 2.32, 95% CI (1.32, 4.1), p = 0.004, I2 = 27%; NNT = 5) and lower risk of cardiac mortality (1.5% vs 4.4%; OR 0.37, 95% CI (0.20, 0.66), p <0.001, I2 = 0%, NNT = 40) compared with furosemide. However, there was no difference in all-cause mortality or medication side effects between the 2 groups. In conclusion, compared with furosemide, torsemide use was associated with significant more improvement in functional status and lower cardiac mortality; and numerically fewer hospitalizations in patients with heart failure.

High-volume forced diuresis with matched hydration using the RenalGuard System to prevent contrast-induced nephropathy: A meta-analysis of randomized trials.
Shah, R, Wood, SJ, Khan, SA, Chaudhry, A, Rehan Khan, M, Morsy, MS
Clinical cardiology. 2017;(12):1242-1246
Abstract
BACKGROUND Contrast-induced nephropathy (CIN) is a well-recognized complication of coronary angiography that is associated with poor outcomes. Several small randomized controlled trials (RCTs) have recently shown that in patients with chronic kidney disease (CKD), furosemide-induced forced diuresis with matched hydration using the RenalGuard system can prevent its occurrence. However, individual studies have been underpowered and thus cannot show significant differences in major clinical endpoints. HYPOTHESIS Forced diuresis with matched hydration using the RenalGuard system improves clinical outcomes in patients undergoing coronary angiography. METHODS Scientific databases and websites were searched for relevant RCTs. The pooled risk ratios were calculated using random-effects models. The primary endpoint was CIN, and the secondary endpoints were major adverse clinical events (MACEs) and the need for renal replacement therapy. RESULTS Data from 3 trials including 586 patients were analyzed. High-volume forced diuresis with matched hydration using the RenalGuard system decreased risk of CIN by 60% (risk ratio: 0.40, 95% confidence interval: 0.25 to 0.65, P < 0.001), MACE rate by 59%, and the need for renal replacement therapy by 78%, compared with the standard of care. CONCLUSIONS In patients with CKD undergoing coronary angiography, high-volume forced diuresis with matched hydration using the RenalGuard system significantly reduces the risk of CIN, MACE rate, and the need for renal replacement therapy. Larger RCTs with sufficient power are needed to confirm these findings.

Abstract
We conducted a meta-analysis of pharmacogenomic substudies of three randomized trials conducted in patients with decompensated heart failure (HF) that were led by National Heart Lung and Blood Institute (NHLBI)-funded HF Network to test the hypothesis that candidate genes modulate net fluid loss and weight change in patients with decompensated HF treated with a furosemide-based diuretic regimen. Although none of the genetic variants previously shown to modulate the effects of loop diuretics in healthy individuals were associated with net fluid loss after 72 h of treatment, a set of rare variants in the APOL1 gene, which codes for apolipoprotein L1 (P=0.0005 in the random effects model), was associated with this end point. Moreover, a common variant in the multidrug resistance protein-4 coding gene (ABCC4, rs17268282) was associated with weight loss with furosemide use (P=0.0001). Our results suggest that both common and rare genetic variants modulate the response to a furosemide-based diuretic regimen in patients with decompensated HF.

Abstract
BACKGROUND Blood transfusions are associated with significant morbidity and mortality. Prophylactic administration of loop diuretics (furosemide, bumetanide, ethacrynic acid, or torsemide) is common practice, especially among people who are at risk for circulatory overload, pulmonary oedema or both. OBJECTIVES This review aimed to determine if the prophylactic administration of loop diuretics (furosemide, bumetanide, ethacrynic acid, or torsemide) provides a therapeutic advantage (that is, a favourable risk benefit ratio) in adults and children who are recipients of any blood product transfusion versus placebo, no treatment, or general fluid restriction measures. SEARCH METHODS We searched the Cochrane Renal Group's Specialised Register to 13 January 2015 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA All randomised controlled trials (RCTs) and quasi-RCTs assessing a loop diuretic in patients receiving any blood transfusion were considered for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently assessed study quality and extracted data. Study authors were contacted for additional information. Results were to be expressed as risk ratios (RR) and their 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) and 95% CI for continuous outcomes. Mean effect sizes were to be calculated using the random-effects models. MAIN RESULTS We included four studies that involved 100 participants. Furosemide was the only diuretic investigated in all four studies.None of the included studies assessed the clinically important outcomes noted in our protocol. The studies focused on various markers of respiratory function. An improvement in fraction of inspired oxygen (in favour of furosemide) was noted in one study. An improvement in pulmonary capillary wedge pressure (in favour of furosemide) was noted in two studies. AUTHORS' CONCLUSIONS There was insufficient evidence to determine whether premedicating people undergoing blood transfusion with loop diuretics prevents clinically important transfusion-related morbidity. Due to the continued use of prophylactic loop diuretics during transfusions, and because this review highlights the absence of evidence to justify this practice, well-conducted RCTs are needed. Given the high mortality, severe morbidity and increasing incidence of transfusion-associated circulatory overload, determining the therapeutic utility of pre-transfusion loop diuresis is an urgent need.

Abstract
BACKGROUND The clinical efficacy of furosemide administration in preventing contrast-induced nephropathy (CIN) remains uncertain. This meta-analysis was designed to update data on the incidence of CIN with additional furosemide treatment beyond saline hydration in comparison with hydration alone in patients undergoing percutaneous coronary intervention (PCI). MATERIAL/METHODS A computerized literature search of MEDLINE, EMBASE, and Cochrane databases was performed. Trials were eligible if they enrolled patients undergoing coronary angiography and randomly allocated participants to receive furosemide administration in addition to saline hydration or saline hydration alone. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for combinations of studies. RESULTS Five trials involving 1294 patients (640 for additional furosemide treatment and 654 for hydration alone) were included in the meta-analysis. In the synthesis of data, additional furosemide administration had little impact on the incidence of CIN post-PCI compared with peri-procedural saline hydration alone (OR=0.96; 95% CI 0.33-2.84, p=0.95). Moreover, as for the subsequent need for dialysis, there was no statistical significant difference between the 2 groups (OR=1.01; 95% CI 0.38-2.67, p=0.99). Sensitivity analyses did not show any relevant influence on the overall results. There was no publication bias in the meta-analysis. CONCLUSIONS Furosemide administration did not achieve additional benefit beyond saline hydration in reducing the incidence of CIN in patients undergoing PCI.

Hypertonic saline with furosemide for the treatment of acute congestive heart failure: a systematic review and meta-analysis.
Gandhi, S, Mosleh, W, Myers, RB
International journal of cardiology. 2014;(2):139-45
Abstract
BACKGROUND Advanced congestive heart failure (CHF) therapies include intravenous inotropic agents, change in class of diuretics, and venous ultrafiltration or hemodialysis. These modalities have not been associated with improved prognosis and are limited by availability and cost. Compared to high-dose furosemide alone, concomitant hypertonic saline solution (HSS) administration has demonstrated improved clinical outcomes with good safety profile. METHODS A literature search was conducted for randomized controlled trials that investigated the use of HSS in patients admitted to hospital with acute CHF. RESULTS 1032 patients treated with HSS and 1032 controls, demonstrated decreased all-cause mortality in patients treat with HSS with RR of 0.56 (95% CI 0.41-0.76,p=0.0003). 1012 patients treated with HSS and 1020 controls, demonstrated decreased heart failure hospital readmission with RR of 0.50 (95% CI 0.33-0.76,p=0.001). Patients treated with HSS also demonstrated decreased hospital length of stay (p=0.0002), greater weight loss (p<0.00001), and preservation of renal function (p<0.00001). CONCLUSION The results of this meta-analysis demonstrate that in patients with advanced CHF concomitant hypertonic saline administration improved weight loss, preserved renal function, and decreased length of hospitalization, mortality and heart failure rehospitalization. A future adequately powered, multi-centre, placebo controlled, randomized, double dummy, blinded trial is needed to assess the benefit of hypertonic saline in patients with renal dysfunction, in diverse patient populations, as well using a patient population on optimal current heart failure treatment. Pending further validation, there is promise for hypertonic saline as an advanced therapy for the management of acute advanced CHF.

Continuous infusion versus intermittent bolus furosemide in ADHF: an updated meta-analysis of randomized control trials.
Amer, M, Adomaityte, J, Qayyum, R
Journal of hospital medicine. 2012;(3):270-5
Abstract
OBJECTIVE Administering intermittent boluses of furosemide to patients with acute decompensated heart failure (ADHF) often leads to unfavorable hemodynamic changes. Continuous infusion may induce similar or greater diuresis without adverse hemodynamic consequences. We conducted a systemic review and meta-analysis of randomized clinical trials that compared the effects of continuous infusion and intermittent bolus of furosemide in patients hospitalized with ADHF. METHODS We searched PubMed, EMBASE, and The Cochrane Central Register of Controlled Trials databases from their inception until March 2011. Two investigators independently abstracted data on study characteristics, quality, and selected outcomes. Differences between investigators were resolved by mutual consensus. Comparisons were reported as the weighted mean difference (WMDs). RESULTS Ten trials involving a total of 564 patients were included. When administered as a continuous infusion, furosemide resulted in greater diuresis (WMD, -240.54 mL/24 hours/100 mg furosemide; 95% confidence interval [CI], -462.42 to -18.66) and reduction in total body weight (WMD, -0.78 kg; 95% CI, -1.54 to -0.03), than when administered in intermittent boluses. Urinary sodium excretion (WMD, -20.26 mmol/24 hours; 95% CI, -60.48 to 19.96) and duration of hospital stay (WMD, 0.99 days; 95% CI, -2.08 to 4.06) were not different between the 2 groups. CONCLUSION This meta-analysis showed statistical support for administering furosemide as a continuous infusion for greater diuresis and reduction in total body weight in patients hospitalized with ADHF. With the exception of greater diuresis, available data are homogenous for the reported outcomes but lack information on clinical endpoints. Larger studies are needed to provide robust recommendations for clinical practice.

Nebulized furosemide for the management of dyspnea: does the evidence support its use?
Newton, PJ, Davidson, PM, Macdonald, P, Ollerton, R, Krum, H
Journal of pain and symptom management. 2008;(4):424-41
Abstract
Dyspnea is a common and distressing symptom associated with multiple chronic illnesses and high levels of burden for individuals, their families and health care systems. The subjective nature dyspnea and a poor understanding of pathophysiological mechanisms challenge the clinician in developing management plans. Nebulized furosemide has been identified as a novel approach to dyspnea management. This review summarizes published studies, both clinical and experimental, reporting the use of nebulized furosemide. The search criteria yielded 42 articles published in the period 1988 to 2004. Although nebulized furosemide appeared to have a positive influence on dyspnea and physiological measurements, caution must be taken with the results primarily coming from small-scale clinical trials or observation trials. Despite the limitations of the studies reported, given the range of conditions reporting effectiveness of nebulized furosemide, further investigation of this potential novel treatment of dyspnea is warranted.
