Outcomes Among Racial and Ethnic Minority Groups with X-linked Agammaglobulinemia from the USIDNET Registry

Health disparities are defined as undesirable health-related differences among groups associated with social, economic, and environmental factors.1 There are limited reports on health disparities among patients with rare primary immunodeficiency disorders (PIDs), including B-cell disorders such as X-linked agammaglobulinemia (XLA), where the reported prevalence is higher in White patients compared to Black and Hispanic patients.1,2 Studying and learning about health care disparities is a crucial initial step toward lessening them, which may be particularly important in rare disorders such as PIDs.
