Inflammatory pathways in transfusion-associated circulatory overload.

ABSTRACT: Transfusion-associated circulatory overload (TACO) is a leading cause of transfusion-associated mortality. TACO is thought to result from hydrostatic forces in the vascular space, leading to transudative pulmonary edema. Recent studies suggest that TACO is not solely a volume overload phenomenon, but may involve inflammatory processes. This study aimed to further explore the presence of inflammation in patients with TACO. We conducted a retrospective study with 3 cohorts receiving red blood cell transfusion: (1) patients having TACO as defined by a national hemovigilance case surveillance classification (conventional TACO [cTACO], n = 33); (2) patients having symptoms consistent with TACO but not completely meeting reporting criteria (institutional TACO [iTACO], n = 33); and (3) a patient
