Features, reason for testing, and changes with time of 583 paroxysmal nocturnal hemoglobinuria clones from 529 patients: a multicenter Italian study.

In this study, we aimed at disclosing the main features of paroxysmal nocturnal hemoglobinuria (PNH) clones, their association with presentation syndromes, and their changes during follow-up. A large-scale, cooperative collection (583 clones from 529 patients) of flow cytometric and clinical data was entered into a national repository. Reason for testing guidelines were provided to the 41 participating laboratories, which followed the 2010 technical recommendations for PNH testing by Borowitz.

Diagnostic accuracy and prognostic value of the CD64 index in very low birth weight neonates as a marker of early-onset sepsis.

Objective: To assess the diagnostic and prognostic utility of CD64 expression as a marker of early-onset sepsis (EOS) in very low birth weight (VLBW) neonates.

Methods: Neutrophil CD64 expression (CD64 index) was assessed in 129 VLBW neonates within 72 h after birth. The accuracy of the CD64 index in predicting EOS was determined by receiver operating characteristic curve analysis.

Congenital Plasmodium vivax malaria mimicking neonatal sepsis: a case report.

Although malaria in pregnancy can cause very significant neonatal morbidity, congenital malaria is a very rare condition in both endemic and non-endemic areas. A case of congenital malaria by Plasmodium vivax, initially mistaken for neonatal sepsis, is described. The correct diagnosis was accidentally done, as congenital malaria had been missed in the initial differential diagnosis.
