Understanding neutropenia in children with Duffy-null phenotype

Retrospective Analysis of a Cohort of Duffy-null Associated Neutrophil Count (DANC) Pediatric Patients

Observational Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico · NCT06547931

This study looks at how common and severe low white blood cell counts are in children with a specific genetic trait and whether these low counts are linked to more infections.

What this trial studies

This observational study aims to characterize neutropenia associated with the Duffy-null phenotype in pediatric patients. It focuses on defining the frequency of immune neutropenia and evaluating the severity of neutropenia in this specific cohort. Additionally, the study will assess the potential relationship between varying degrees of neutropenia and the occurrence of infections. Data will be collected and analyzed to provide insights into this condition.

Who should consider this trial

Good fit: Ideal candidates for this study are pediatric patients who exhibit the Duffy-null phenotype.

Not a fit: Patients without the Duffy-null phenotype will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding and management of neutropenia in children with the Duffy-null phenotype.

How similar studies have performed: There is limited existing data on this specific condition, making this approach novel and untested.
