Abstract:Objective To investigate the clinical effects of micafungin combined with continuous renal replacement therapy (CRRT) in patients with sepsis complicated by fungal infection.Methods A total of 100 patients with sepsis complicated by fungal infection who were admitted to The 910th Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from June 2023 to June 2025 were enrolled. According to the treatment received, the patients were divided into a fluconazole group (n = 53) and a micafungin group (n = 47). The fluconazole group received fluconazole combined with CRRT, whereas the micafungin group received micafungin combined with CRRT. Organ function, hemodynamic indices, inflammatory factors, prognostic indicators, and survival were compared between the two groups.Results After treatment, the total bilirubin (TBil) and serum creatinine (Scr) levels and the Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were lower in the micafungin group than in the fluconazole group (P < 0.05). Mean arterial pressure (MAP) was higher, whereas heart rate (HR) and lactate (Lac) levels were lower in the micafungin group (P < 0.05). The levels of C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6) were lower in the micafungin group than in the fluconazole group (P < 0.05). The intensive care unit (ICU) stay was shorter in the micafungin group (P < 0.05). No statistically significant differences were observed between the two groups in the 7-day or 28-day mortality rate or the overall survival rate (P > 0.05).Conclusion Micafungin combined with CRRT has favorable clinical effects in patients with sepsis complicated by fungal infection.
