2 Clinical Trials for Various Conditions
Patients receiving intravenous immunoglobulin (IVIG) therapy for primary immunodeficiency and neurologic conditions may experience adverse drug reactions (ADRs). The mechanism of the ADR is unknown. Currently, the standard practice for these patients is to change from IV to subcutaneous IG (SCIG) but because of the need of immunomodulation or patient preference, SCIG may not be an option. Data has shown that some levels of complement decrease from pre- to post-infusion of IVIG. This study is to determine if replacing this complement protein may ameliorate ADRs.
This is an observational, case-control study with a single blood draw among two cohorts, patients with antibody deficiency (e.g., CVID) and healthy controls. Samples will be analyzed by mass cytometry (CyTOF) to examine the major signaling pathways of all circulating innate and adaptive immune cell types, as well as whole exome sequencing. The goal is to improve our general understanding of the human immune response to infections and the diagnosis of CVID.
