Abstract
Levosimendan and milrinone may be used in place of dobutamine to increase cardiac output in septic patients with a low cardiac output due to impaired cardiac function. The effects of the two inotropic agents on cardiac inflammation and left ventricular (LV) performance were examined in mice with cecal ligation and puncture (CLP)-induced sepsis. CLP mice displayed significant cardiac inflammation, as indicated by highly increased pro-inflammatory cytokines and neutrophil infiltration in myocardial tissues. When continuously given, levosimendan prevented but milrinone exaggerated cardiac inflammation, but they significantly reduced the elevations in plasma cardiac troponin-I and heart-type fatty acid-binding protein, clinical markers of cardiac injury. Echocardiographic assessment of cardiac function showed that the effect of levosimendan, given by an intravenous bolus injection, on LV performance was impaired in CLP mice, whereas milrinone produced inotropic responses equally in sham-operated and CLP mice. A lesser effect of levosimendan on LV performance after CLP was also found in spontaneously beating Langendorff-perfused hearts. In ventricular myocytes isolated from control and CLP mice, levosimendan, but not milrinone, caused a large increase in the L-type calcium current. This study represents that levosimendan and milrinone have cardioprotective properties but provide different advantages and drawbacks to cardiac inflammation/dysfunction in sepsis.

Levosimendan beyond inotropy and acute heart failure: Evidence of pleiotropic effects on the heart and other organs: An expert panel position paper. Int J Cardiol 2016; 222:303-312. [PMID: 27498374 DOI: 10.1016/j.ijcard.2016.07.202] [Citation(s) in RCA: 84] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2016] [Accepted: 07/28/2016] [Indexed: 02/04/2023]
Abstract
Levosimendan is a positive inotrope with vasodilating properties (inodilator) indicated for decompensated heart failure (HF) patients with low cardiac output. Accumulated evidence supports several pleiotropic effects of levosimendan beyond inotropy, the heart and decompensated HF. Those effects are not readily explained by cardiac function enhancement and seem to be related to additional properties of the drug such as anti-inflammatory, anti-oxidative and anti-apoptotic ones. Mechanistic and proof-of-concept studies are still required to clarify the underlying mechanisms involved, while properly designed clinical trials are warranted to translate preclinical or early-phase clinical data into more robust clinical evidence. The present position paper, derived by a panel of 35 experts in the field of cardiology, cardiac anesthesiology, intensive care medicine, cardiac physiology, and cardiovascular pharmacology from 22 European countries, compiles the existing evidence on the pleiotropic effects of levosimendan, identifies potential novel areas of clinical application and defines the corresponding gaps in evidence and the required research efforts to address those gaps.

Abstract
BACKGROUND We aimed to investigate the effect of levosimendan on biomarkers of myocardial injury and systemic hemodynamics in patients with septic shock. MATERIAL AND METHODS After achieving normovolemia and a mean arterial pressure of at least 65 mmHg, 38 septic shock patients with low cardiac output (left ventricular ejective fraction), LEVF £45%) were randomly divided into two groups: levosimendan dobutamine. Patients in the levosimendan and dobutamine groups were maintained with intravenous infusion of levosimendan (0.2 μg/kg/minute) and dobutamine (5 μg/kg/minute) for 24 hours respectively. During treatment we monitored hemodynamics and LVEF, and measured levels of heart-type fatty acid binding protein (HFABP), troponin I (TNI), and brain natriuretic peptide(BNP). In addition, the length of mechanical ventilation, intensive care unit (ICU) stay, hospital stay, and 28-day mortality were compared between the two groups. RESULTS The levosimendan group and the dobutamine group were well matched with respect to age (years, 55.4 ± 1 7.5 versus 50.2 ± 13.6) and gender (males, 68.4% versus 57.9%). Levosimendan-treated patients had higher stroke volume index (SVI), cardiac index (CI), LVEF, and left ventricular stroke work index (LVSWI), and lower extravascular lung water index (EVLWI) compared to dobutamine-treated patients (p<0.05). HFABP, TNI, and BNP in the levosimendan group were less than in the dobutamine group (p<0.05). There was no difference in the mechanical ventilation time, length of stay in ICU and hospital, and 28-day mortality between the two groups. CONCLUSIONS Compared with dobutamine, levosimendan reduces biomarkers of myocardial injury and improves systemic hemodynamics in patients with septic shock. However, it does not reduce the days on mechanical ventilation, length of stay in ICU and hospital, or 28-day mortality.

Abstract
PURPOSE There is controversy about the use of inotropes in the treatment of severe sepsis and septic shock. The objective of this study was to evaluate if levosimendan, as compared with standard inotropic therapy (eg, dobutamine), reduces mortality in septic patients. MATERIALS AND METHODS BioMedCentral, PubMed, EMBASE, and the Cochrane Central Register were searched for pertinent studies, up to 1st May 2015. Randomized trials on the use of levosimendan in patients with severe sepsis and septic shock were included if reporting mortality data. The primary outcome was mortality, whereas secondary outcomes were blood lactate, cardiac index, total fluid infused, norepinephrine dosage, and mean arterial pressure. RESULTS Seven studies for a total of 246 patients were included in the analysis. Levosimendan was associated with significantly reduced mortality compared with standard inotropic therapy (59/125 [47%] in the levosimendan group and 74/121 [61%] in the control group; risk difference = -0.14, risk ratio = 0.79 [0.63-0.98], P for effect = .03, I(2) = 0%, numbers needed to treat = 7). Blood lactate was significantly reduced in the levosimendan group, whereas cardiac index and total fluid infused were significantly higher in the levosimendan group. No difference in mean arterial pressure and norepinephrine usage was noted. CONCLUSIONS In patients with severe sepsis and septic shock, levosimendan is associated with a significant reduction in mortality compared with standard inotropic therapy. A large ongoing multicenter randomized trial will have to confirm these findings.

Abstract
To investigate the effects of dobutamine hydrochloride on early postoperative cognitive dysfunction (POCD) and plasma tumor necrosis factor (TNF)-α concentration in patients undergoing hip arthroplasty, 124 patients undergoing unilateral total hip arthroplasty, aged 70-92 years old, were randomly assigned to four groups (n=31) as follows: a control group of patients receiving only saline (intravenous infusion, i.v.); and groups receiving 2, 4, or 6μgkg(-1)min(-1) (i.v.) of dobutamine hydrochloride. Cognitive functions were assessed on the day before surgery (T1), and the 1st day (T2), 3rd day (T3), and 7th day (T4) postsurgery using the Mini Mental State Examination (MMSE). The plasma TNF-α protein level was determined 10min before anesthesia (Ta), and 10min (Tb), 30min (Tc), and 60min (Td) after anesthesia by an enzyme-linked immunosorbent assay. Cognitive disorder was observed within the first 3 days after hip arthroplastic surgery, and it had recovered 7 days after the operation in the control group of patients. Administration of 2 or 4μgkg(-1)min(-1) dobutamine hydrochloride was able to reverse the early POCD. Simultaneously, an increase of plasma TNF-α levels 30min after anesthesia was observed (41.34±9.61 vs. 27.75±5.45), which was significantly suppressed by the administration of low-dose dobutamine hydrochloride (29.23±7.32 vs. 41.34±9.61) but not by high-dose dobutamine hydrochloride (45.9±12.11 vs. 41.34±9.61). Together, our data indicated that the plasma concentration of TNFα was engaged in the effect of dobutamine hydrochloride on POCD.

Abstract
INTRODUCTION The purpose of the present study was to investigate microcirculatory blood flow in patients with septic shock treated with levosimendan as compared to an active comparator drug (i.e. dobutamine). The primary end point was a difference of ≥ 20% in the microvascular flow index of small vessels (MFIs) among groups. METHODS The study was designed as a prospective, randomized, double-blind clinical trial and performed in a multidisciplinary intensive care unit. After achieving normovolemia and a mean arterial pressure of at least 65 mmHg, 40 septic shock patients were randomized to receive either levosimendan 0.2 μg·kg(-1)·min(-1) (n = 20) or an active comparator (dobutamine 5 μg·kg(-1)·min(-1); control; n = 20) for 24 hours. Sublingual microcirculatory blood flow of small and medium vessels was assessed by sidestream dark-field imaging. Microcirculatory variables and data from right heart catheterization were obtained at baseline and 24 hours after randomization. Baseline and demographic data were compared by means of Mann-Whitney rank sum test or chi-square test, as appropriate. Microvascular and hemodynamic variables were analyzed using the Mann-Whitney rank sum test. RESULTS Microcirculatory flow indices of small and medium vessels increased over time and were significantly higher in the levosimendan group as compared to the control group (24 hrs: MFIm 3.0 (3.0; 3.0) vs. 2.9 (2.8; 3.0); P = .02; MFIs 2.9 (2.9; 3.0) vs. 2.7 (2.3; 2.8); P < .001). The relative increase of perfused vessel density vs. baseline was significantly higher in the levosimendan group than in the control group (dMFIm 10 (3; 23)% vs. 0 (-1; 9)%; P = .007; dMFIs 47 (26; 83)% vs. 10 (-3; 27); P < .001). In addition, the heterogeneity index decreased only in the levosimendan group (dHI -93 (-100; -84)% vs. 0 (-78; 57)%; P < .001). There was no statistically significant correlation between systemic and microcirculatory flow variables within each group (each P > .05). CONCLUSIONS Compared to a standard dose of 5 μg·kg(-1)·min(-1) of dobutamine, levosimendan at 0.2 μg·kg(-1)·min(-1) improved sublingual microcirculatory blood flow in patients with septic shock, as reflected by changes in microcirculatory flow indices of small and medium vessels.

Abstract
Asiaticoside (AS), a major triterpenoid saponin component isolated from Centella asiatica, has been described to exhibit antioxidant and anti-inflammatory activities. The present study aimed to determine the protective effects and the underlying mechanisms of AS on septic lung injury induced by cecal ligation and puncture (CLP). Mice were pretreated with the AS (45 mg/kg) or AS as well as GW9662 at 1h before CLP, the survival, lung injury, inflammatory mediators and signaling molecules, and Peroxisome proliferator-activated receptor-γ (PPAR-γ) were determined 24 h after CLP. The results showed that AS significantly decreased CLP-induced the mortality, lung pathological damage, the infiltration of mononuclear, polymorphonuclear (PMN) leucocytes and total proteins. Moreover, AS inhibited CLP-induced the activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-κB (NF-κB), the expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) protein in lung tissues, and the production of serum tumor necrosis factor (TNF-α) and interleukin-6 (IL-6). Interestingly, the expression of PPAR-γ protein in lung tissue was up-regulated by AS. Furthermore, GW9662 (the inhibitor of PPAR-γ) significantly reversed these beneficial effects of AS in septic mice. These findings suggest that AS could effectively protect from septic lung injury induced by CLP and the underlying mechanisms might be related to up-regulation of PPAR-γ expression to some extent, which inhibits MAPKs and NF-κB pathway.

Abstract
PURPOSE This study aimed to investigate the apoptotic mechanisms, oxidative stress, and mechanisms of effect of antibiotics and ursodeoxycholic acid (UDCA) in total parenteral nutrition (TPN)-associated liver injury. METHODS Four groups of young rabbits were used in the study as follows: Group 1 (n: 7): TPN + Metronidazole (30 mg/kg IV) + Gentamicin (6 mg/kg IV); Group 2 (n: 7): TPN + UDCA (15 mg/kg per oral); Group 3 (n: 6): TPN only; and Group 4 (n: 7): Control group. After 10 days, the animals were killed and livers were removed. Hepatic apoptosis, apoptotic proteins, malondialdehyde (MDA) and myeloperoxidase (MPO) levels were studied in liver, and direct bilirubin values were assessed in the blood samples. RESULTS Direct bilirubin increased with TPN, and antibiotic combination, as the most effective group, significantly lowered its levels (p < 0.01). MDA values also showed significant differences in comparisons between G1 and G3 (p < 0.05) and G1-G4 (p < 0.01). An increased number of apoptotic cells was detected particularly in G2 and G3, whereas the lowest levels, other than in the control group, were found in G1. All TUNEL-positive cell number data were statistically significant except between G2 and G3(p < 0.05). Caspase-3 and Bax immunoreactivities were greatest in G2. Significant differences were shown in caspase-3 immunoreactivity between the groups (p < 0.01), except between G1 and G3 (p > 0.05). All comparisons between the groups were significant for Bax (p < 0.01). In contrast, Bcl-2 immunoreactivity was moderate and highest in G1: comparisons between G1 and the other groups demonstrated statistically significant differences (p < 0.01). Fas-L immunoreactivity was greatest in G2, and all comparisons between the groups were statistically significant (p < 0.01). CONCLUSIONS Metronidazole and gentamicin combination is effective on TPN-induced liver injury by the Bcl-2 anti-apoptotic pathway, total anti-apoptotic effect and by decreasing bilirubin levels. Oxidative injury in the liver increased with therapy. UDCA seems less effective on TPN-associated liver injury.
