Sickle cell disease (SCD) is a chronic, incurable hereditary disease. The vaso-occlusive crisis (VOC) is the most frequently occurring acute complication in sickle cell patients and accounts for the majority of SCD-related hospital admissions. Another major complication is the potentially fatal acute chest syndrome (ACS). The prototypic long pentraxin-3 (PTX3), an acute phase protein and a key component of innate immunity, is linked to ischemia-induced inflammation, a condition incriminated in SCD complications. ⋯ PTX3 levels were higher in SCD patients in VOC, being associated with longer hospital stay. Higher initial PTX3 concentrations were related to the development of ACS with a further increase in PTX3 levels observed upon progression to ACS. Thus, PTX3 could be used as a subjective method to predict occurrence and severity of SCD acute complications.
