Hemostatic Manifestations of Invasive Fungal Infections: A Comprehensive Review of Pathophysiological Mechanisms in Sepsis-Induced Hemostatic Disturbances, with a Focus on the Neonatal Population.

Sepsis is a life-threatening condition that has challenged many clinicians over the years. The immune and hemostatic systems are the primary pillars of sepsis pathogenesis. Dysregulation of these intricate mechanisms significantly worsens the prognosis. Coagulopathy is a critical aspect of sepsis, with the degree of hemostatic impairment being a key determinant of poor outcomes. Although the concept of sepsis caused by bacteria has been well investigated, the fungal impact in the complexity of sepsis related hemostatic derangement is not yet fully unraveled. In addition, sepsis occurs in patients across all age groups, with a particular concern for neonates, whose immature and vulnerable systems amplify the challenges. Notably, despite the high incidence of fungal septicemia in neonatal intensive care units (NICUs), along with its significant morbidity, mortality, and adverse neonatal outcomes, the impact of fungal sepsis on the neonatal hemostatic system-an essential determinant of prognosis-remains largely unexplored. The present review delves into the pathophysiologic mechanisms of sepsis induced coagulopathy attributed to fungal infection, the mechanisms of fungal involvement in the hemostatic derangement and attempts to contextualize this knowledge within the unique neonatal population. Finally, it aims to raise awareness of the critical need for a deep understanding of this hazardous condition in order to guide the development of optimal therapeutic strategies.
