| Summary: | Sepsis is a life-threatening condition driven by a dysregulated host immune response to infection, with cytokine overproduction contributing to organ dysfunction and high mortality. Levosimendan, a calcium sensitizer used in acute heart failure, has been proposed to exert anti-inflammatory effects, but information on its immunomodulatory effects in early sepsis remains scarce. This study aimed to investigate the dose- and time-dependent effects of levosimendan on cytokine profiles in a rat model of lipopolysaccharide (LPS)-induced sepsis. Thirty-two male Wistar albino rats were randomly assigned to four groups: sham, sepsis control, low-dose levosimendan (1 mg/kg), and high-dose levosimendan (2 mg/kg). Cytokine levels (TNF-α, IL-1β, IL-6, IL-8, IL-17, MCP-1) were measured at 5 and 10 h post-LPS administration. High-dose levosimendan significantly reduced TNF-α, IL-1β, IL-6, and MCP-1 levels by the 10th hour, accompanied by improved Murine Sepsis Scores. IL-17 and IL-6 showed biphasic responses, increasing initially and decreasing significantly later, particularly with high-dose treatment. IL-8 reduction was observed only in the high-dose group. These findings support levosimendan’s dose and time-dependent anti-inflammatory effects and suggest it may modulate both early and late-phase cytokines in sepsis. Further studies are warranted to clarify its potential role in clinical sepsis management. |
