AbstractObjective : The aim of the study is to investigate the efficacy of intravenous immunoglobulin (IVIg) in treating sepsis-induced coagulopathy ( SIC ). Methods : A retrospective controlled analysis was conducted on 230 patients with SIC at Ganzhou People's Hospital from January 2016 to December 2022. All patients were screened using propensity score matching and treated according to the SSC2016 guidelines. Compared with the control group (n = 115), patients in the test group (n = 115) received IVIg (200 mg/kg.d) for 3 consecutive days after admission. The rating scales, coagulation function, survival, and treatment duration were evaluated. Results : On day 3 of treatment, both groups exhibited reduced platelet and thromboelastogram (TEG) maximum amplitude (MA) levels, with the control group showing a more significant decrease ( P < 0.05). By the fifth day, these levels had recovered in both groups. However, the test group experienced a significant increase by day 7 ( P < 0.05). Coagulation factors II and X began to increase on day 3, and normalization was significantly faster in the test group on day 5 ( P < 0.05). The levels of prothrombin time, international normalized ratio, activated partial thromboplastin time, d -dimer, fibrinogen, fibrin degradation products, TEG-R, and TEG-K exhibited a notable decline on day 3 and demonstrated significantly faster recovery on day 5 in the test group ( P < 0.05). In addition, both groups showed a reduction in Acute Physiology and Chronic Health Evaluation II, Sequential Organ Failure Assessment, disseminated intravascular coagulation, and lactate (LAC) levels on day 3, but the test group's scores decreased significantly more by day 7 ( P < 0.05). Within the test group, white blood cell count, C-reactive protein, procalcitonin, IL-6, and Tmax levels were lower ( P < 0.05). Furthermore, the test group demonstrated shorter duration for intensive care unit stay, mechanical ventilation, and continuous renal replacement therapy ( P < 0.05). No significant differences were observed in the duration of fever or vasoactive drug use between the groups. However, the log-rank method indicated a higher 28-day survival rate in the test group ( P < 0.05). Conclusion : IVIg can successfully increase platelet count and coagulation factors, correct coagulation disorders, enhance organ function, and reduce 28-day mortality in patients with SIC .Copyright © 2024 by the Shock Society.
